Application of coal centrifuge in coal industry

/in /by

With the development of clean coal technology, the coal slime water process in coal preparation plants shall be limited by 0.5mm to determine the classification of coal slime. In order to meet the needs of the market, especially the requirements for dehydration of coal slime with particle size of 2~0.5mm in the separation process segmentation , it is necessary to develop a new type of centrifuge.

In this way, the coal can be recovered to the maximum extent, thereby improving the recovery rate of clean coal, improving the economic benefits of coal preparation enterprises, protecting the environment, and saving energy. Such a centrifuge product has a large processing capacity and low product moisture, which greatly reduces the burden on the coal slime water treatment system, achieves good results, and can simplify the coal slime water treatment process.

The centrifuge machine developed this time is mainly used for the dehydration of 2~0.5mm fine coal. The coal centrifuge has the characteristics of small investment, small system transformation, and good process effect. It will become the first choice for the transformation of old plants and new coal preparation plants. , due to the small particle size of the separated solid particles, it can not only be used in the coal preparation industry, but also suitable for solid-liquid separation in the chemical, pharmaceutical, food and environmental protection industries, with good business and social prospects!

The separation and dehydration of coal centrifuge is to use gravity, mechanical force or heating and drying methods to separate solids and liquids to reduce the moisture content of wet materials. The use of wet dehydration operation is an important part of coal preparation in coal preparation plants. The main purpose of coal centrifuge dehydration separation is:

coal centrifuge

(1) Reduce the moisture in coal preparation products to ensure the transportation needs. In coal preparation plants, the comprehensive moisture content of various clean coals is generally required to reach 8% to 10%, and the requirement in alpine regions is below 8%. Wet coal preparation will contain a lot of moisture. If coking coal is used for coal preparation, the coal moisture will be high, not only the coking time will be longer, the production volume will be reduced, the amount of gas used for the coke oven will be larger, and the service life will be shortened.

(2) Wash and reuse to save water. Wet coal preparation consumes a lot of water. Under normal circumstances, the jig machine uses 3 tons of water for processing 1 ton of raw coal; 1 ton of raw coal uses 0.7 tons of water, and 1 ton of fine coal requires about 1.2 to 2.0 tons of water, so our water resources will cause a lot of waste.

In addition, before wind coal preparation, if the coal contains a lot of water, it needs to be dehydrated first. Coal separation and dehydration methods include: gravity dehydration, mechanical dehydration, thermal dehydration, physical chemistry, etc. Several commonly used methods are: gravity dehydration, mechanical centrifugal dehydration and thermal heating dehydration. In the coal preparation plant, the dehydration of coal is carried out in stages.

Cause Analysis and Repair Scheme of Welding Seam Cracking in Concrete Mixer Truck Raceway

/in /by

The mixing drum is the key component of the concrete mixer truck for loading, mixing and transporting concrete. A flange is welded at the head of the mixing drum, and a raceway is welded at the rear cone. The mixing drum is driven by the reducer, and is supported by the rollers in rolling contact with the raceway to rotate, so as to realize the loading and unloading and mixing functions of concrete. Due to the eccentric load generated by the concrete mixer truck during mixing and the starting and braking of the vehicle on complex roads, the force on the mixing drum is extremely complex, and the design or welding process defects may lead to cracking of the raceway welds. The concrete mixer truck manufacturer analyzes the cause of the cracking of the raceway weld and proposes a repair plan.

Cause Analysis of Weld Cracking

When the mixing drum is working, in addition to the bending moment caused by the self-weight of the drum and the weight of the concrete, it also bears the torque action caused by the rotary motion of the mixing drum and the force of the concrete in the circumferential and axial directions in the mixing drum. force is more complicated. Under the action of cyclic alternating load, initial micro-cracks may form in areas of high stress, and then develop into macro-cracks, and then the macro-cracks will continue to expand, eventually leading to cracking of the weld bead or base metal.

The main reasons for the initial microcracks affecting the raceway are as follows:

concrete-mixer-truck

(1) Stress concentration at the raceway weld

Reason: When the raceway and the cylinder are welded, stress concentration often occurs at the weld. In addition, during the use of the mixing drum, the concentrated load at the raceway and the supporting roller and the overall deformation of the raceway section will also cause stress concentration at the weld.

Countermeasures: Grind the stress concentration weld and re-weld. For the weld or base metal with macro cracks, punch holes to cut off the source of the crack and re-weld.

DETAILED EXPLANATION OF COLD FORGING FORMING PROCESS

/in /by

Cold forging is a general term for plastic processing such as cold die forging, cold extrusion, and cold heading. It is the forming process of the material below the recrystallization temperature, and the forging is carried out below the recovery temperature. In production, forging without heating the blank is called cold forging.

Most of the cold forging materials are aluminum and some alloys, copper and some alloys, low carbon steel, medium carbon steel, and low alloy structural steel with low deformation resistance and good plasticity at room temperature. Cold forgings have good surface quality and high dimensional accuracy, which can replace some cutting processes. Cold forging can strengthen the metal and increase the strength of the part.

INTRODUCTION OF COLD FORGING PROCESS

Locomotive forgings

Cold precision forging is a (near) net shape forming process. The parts formed by this method have high strength and precision and good surface quality. At present, the total amount of cold forgings used in an ordinary car abroad is 40~45kg, of which the total amount of toothed parts is more than 10kg. The single-piece weight of cold forged gears can reach more than 1kg, and the tooth shape accuracy can reach 7 grades.

Continuous process innovation has promoted the development of cold extrusion technology. Since the 1980s, domestic and foreign precision forging experts have begun to apply the split forging theory to the cold forging of spur and helical gears. The main principle of shunt forging is to establish a shunt cavity or shunt channel of material in the forming part of the blank or die.
