Nowadays, life is constantly progressing and developing. Of course, it also produces a lot of negative things. There are more and more garbage around us. If we do not deal with it in time, we will soon be buried by garbage. Generally speaking, garbage incineration is still a Now we use the common way of dealing with garbage. In order to prevent the continuous infestation of harmful substances, we can add calcium hydroxide to it.

I believe that friends who see it here will be confused and wonder if they are wrong. Yes, you read that right! In order to let everyone know how widely used calcium hydroxide is, the following calcium hydroxide production line manufacturers will introduce to you the applications of calcium hydroxide in waste incineration.

APPLICATION OF CALCIUM HYDROXIDE IN WASTE INCINERATION:

1. Garbage incineration is a method used by most cities to dispose of garbage. Therefore, incinerators have been built in various places. After the garbage is treated by incineration, the amount of garbage can be reduced, and land use can also be saved. Such a process can also eliminate a large number of pathogens and convert toxic and harmful substances into non-toxic and harmful substances.

2. For the flue gas generated during the combustion process, the flue gas temperature drops sharply from more than 400 degrees Celsius to about 120 degrees Celsius. After that, the activated carbon and calcium hydroxide are deacidified in the reaction tower, and the activated carbon adsorbs harmful gases such as dioxins; The flue gas enters the dust collector, is adsorbed to remove particulate matter, heavy metals, etc. in the flue gas, and then is discharged into the atmosphere through the chimney.

We know that the quality of the slewing bearing itself is the main factor affecting the service life of the bearing, but no, because in addition to the quality of the bearing, there is also a very important issue, that is, the maintenance and maintenance of the bearing during its use, but, How to maintain the slewing bearing during use?

Lubrication of slewing bearing

1. Lubrication

(1) Reduce friction and wear. In the mutual contact parts of the rings, rolling elements and cages that constitute the bearing, metal contact is prevented, and friction and wear are reduced.

(2) Extend the fatigue life. The rolling fatigue life of the bearing is extended when the rolling contact surface is well lubricated during rotation. Conversely, if the oil viscosity is low and the lubricating oil film thickness is not good, it will be shortened.

(3) Discharge frictional heat and cooling. The oil circulation method, etc., can use oil to discharge heat generated by friction or heat from the outside, and cool it. Prevent the bearing from overheating and prevent the aging of the lubricating oil itself.

(4) Others. It also has the effect of preventing foreign matter from entering the inside of the bearing, or preventing rust and corrosion.

2. Lubrication method

Bearing lubrication methods are divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to select a lubrication method suitable for the conditions of use and the purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing. Compare the advantages and disadvantages of grease lubrication and oil lubrication.

Cleaning of slewing bearing

1. Selection of cleaning materials

As the cleaning agent, cleaning agent and kerosene are generally used. In addition, pay attention to sealing the cleaning agent when not in use to avoid the entry of external magazines and contaminating the cleaning agent. In the case of inattentiveness, cleaning the bearing with the contaminated cleaning agent will not only not have a cleaning effect, but will contaminate the bearing and cause the bearing to be polluted. Running brings stress.

The conveyor is mainly used for the transportation of materials. It has the point that the direction is changeable and the conveying direction can be flexibly changed. We commonly have screw conveyors and belt conveyors, etc. Among them, belt conveyors are the main way of conveying bulk materials. When we use or maintain the machine improperly, the conveyor may fail and cause downtime. Do you know the reason for the downtime of the conveyor?

Reasons for screw conveyor downtime

The screw conveyor has the advantages of small cross-sectional size of the whole machine, good sealing performance, multi-point loading and unloading in the middle, and easy operation and maintenance. It is suitable for conveying powdery, granular and small block materials. It is widely used in building materials, metallurgy, Chemical, electric power, coal, machinery, grain, food and other industries; it is not suitable to transport materials that are perishable, viscous, and easy to agglomerate.

The reasons for the stoppage of the screw conveyor are:

1. The material is too large

Problem: The material to be conveyed is too large, the material cannot pass through the middle hanging bearing smoothly, and the material resistance at the middle bearing is too large, causing the screw conveyor to stop suddenly.

Solution: judge the size of the material before conveying to avoid the material being too large and stuck in the middle of the hanging bearing, resulting in downtime.

2. Material blockage

Problem: Blockage of material in the screw conveyor can also cause the motor to be overloaded and shut down.
Solution: We must clean up the material in the screw conveyor, keep the conveyor unobstructed, and install a belt cleaner to avoid blockage due to excessive viscosity of the material.

3. Seal damage

Problem: The resistance at the intermediate bearing is too large and the seal is damaged. Material entering the bearing causes the bearing not to rotate or the bearing is damaged.

Solution: The seal needs to be replaced, and the abnormality at the intermediate bearing should be checked for repair.

4. Bearing burnt

Problem: The reducer bearing is burnt, resulting in downtime.

Solution: Replace the new parts to ensure the normal operation of the machine.

Forging is a processing method that uses a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size. Forging (forging and stamping) is one of the two major components. Through forging, defects such as as-cast looseness generated in the metal smelting process can be eliminated, and the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings of the same material. For important parts with high load and severe working conditions in related machinery, forgings are mostly used in addition to rolling plates, profiles or welded parts with simple shapes.

The initial recrystallization temperature of steel is about 727 °C, but 800 °C is generally used as the dividing line, and hot forging is higher than 800 °C; between 300 and 800 °C, it is called warm forging or semi-hot forging. called cold forging.

Forgings used in most industries are hot forging. Warm and cold forging are mainly used for forging parts such as automobiles and general machinery. Warm and cold forging can effectively save materials.

PROCESS CLASSIFICATION

According to the forging temperature, it can be divided into hot forging, warm forging and cold forging.

According to the forming mechanism, forging can be divided into free forging, die forging, ring rolling and special forging.

1. FREE FORGING

It refers to the processing method of forgings that use simple universal tools or directly apply external force to the blank between the upper and lower anvils of the forging equipment to deform the blank to obtain the required geometric shape and internal quality. Forgings produced by the free forging method are called free forgings. Free forging is mainly based on the production of small batches of forgings. Forging equipment such as forging hammers and hydraulic presses are used to form and process the blanks to obtain qualified forgings. The basic processes of free forging include upsetting, drawing, punching, cutting, bending, torsion, offset and forging. Free forging is all hot forging.

Advantages: Free forging has the characteristics of flexible process, high versatility of equipment and tools, and low cost. Since free forging is formed gradually, the required deformation force is small, so it is the only way to produce large forgings (above 300T).

Disadvantages: low productivity, low precision forgings, high labor intensity, mostly used for single-piece and small batch production of forgings with simple shapes and low precision requirements.

2. DIE FORGING

Die forging is divided into open die forging and closed die forging. The metal blank is compressed and deformed in a forging die cavity with a certain shape to obtain a forging. Die forging is generally used to produce parts with small weight and large batches. Die forging can be divided into hot forging, warm forging and cold forging. Warm forging and cold forging are the future development direction of die forging, and also represent the level of forging technology.

According to the material, die forging can also be divided into ferrous metal die forging, non-ferrous metal die forging and powder product forming. As the name implies, the materials are ferrous metals such as carbon steel, non-ferrous metals such as copper and aluminum, and powder metallurgy materials. Extrusion should belong to die forging, which can be divided into heavy metal extrusion and light metal extrusion.

Closed die forging and closed upsetting are two advanced processes of die forging. Since there is no flash, the utilization rate of materials is high. It is possible to complete the finishing of complex forgings in one or several operations. Since there is no flash, the stressed area of ​​the forging is reduced and the required load is also reduced. However, it should be noted that the blank cannot be completely restricted. For this reason, the volume of the blank should be strictly controlled, the relative position of the forging die should be controlled and the forging should be measured, and efforts should be made to reduce the wear of the forging die.

3. ROLLING RING

Ring rolling refers to the production of ring-shaped parts of different diameters through special equipment ring-grinding machines, and is also used to produce wheel-shaped parts such as automobile hubs and train wheels.

4. SPECIAL FORGING

Special forging includes roll forging, cross wedge rolling, radial forging, liquid die forging and other forging methods, which are more suitable for the production of parts with special shapes. For example, roll forging can be used as an effective preforming process to greatly reduce the subsequent forming pressure; cross wedge rolling can produce parts such as steel balls and drive shafts; radial forging can produce large forgings such as barrels and stepped shafts.
