Description

Technical Field

[0001] The invention relates to the field of belt filter presses, in particular to a novel belt filter press loosening device for fine-grained coal. Background Art

[0002] At present, more than 90% of my country's coal is cleaned by wet method, and the processing volume of suspension in the coal cleaning process is as high as 6 billion m 3 / year, which gathers a large number of fine coal particles (less than 45μm), clay minerals that are easy to sludge and swell, such as kaolinite, montmorillonite, illite, and multi-ion components, forming a high-concentration complex unstable dispersion system. Coal slurry water has become one of the main sources of pollution in the coal industry. If the chemical agents remaining in the flotation, concentration and filtration stages and the various metal ions associated with coal are discharged with water, they will cause great harm to the water area and seriously pollute the surrounding environment. In order to use coal cleanly, the solid-liquid separation of fine coal is an indispensable process in the coal preparation plant. Effective dehydration of fine coal not only determines the clarity of circulating water and the recovery rate of coal slurry, but also affects the production efficiency of other production links, and also has a great impact on product quality and subsequent transportation links. Belt filter press is a highly efficient solid-liquid separation equipment, which has been widely used in the dehydration of materials such as coal preparation products, hydrometallurgical residues, and municipal sludge.

[0003] The fine coal to be processed is transported to the feed end of the belt filter medium (rubber belt) through a hopper. During the transmission of the fine coal on the rubber belt, the solid particles are suspended in the liquid and filtered through the filter holes of the rubber belt. The liquid enters the interior of the rubber belt through the filter holes, and the solids are retained on the surface to form a solid filter layer. Pressure is applied to the rubber belt in the form of a roller to gradually thicken the solid filter layer and promote the dehydration of the solid particles.

[0004] When feeding, fine coal is directly put into the feed hopper of the belt filter press, which is convenient for filtering the fine coal. However, the fine coal is easy to agglomerate during transportation and feeding, resulting in uneven distribution of the fine coal. Direct feeding makes the filtering effect of the filter press poor, which is not conducive to the reuse of the fine coal. Summary of the invention

[0026] On the outer sides of the front and rear limiting plates 407, two mounting blocks 418 are fixedly connected. A connecting pipe 419 is fixedly connected between the two mounting blocks 418. A plurality of suction heads 420 are fixedly connected to the outer side of the connecting pipe 419. A U-shaped pipe 421 is fixedly connected between the front and rear connecting pipes 419. A collection box 423 and an air box 424 are fixedly connected to the rear side of the vertical plate 3. A conveying pipe 422 is fixedly connected between the collection box 423 and the U-shaped pipe 421. A communicating pipe 431 is fixedly connected between the collection box 423 and the air box 424. An air outlet pipe 430 is fixedly connected to the upper side of the air box 424. The rear end of the eccentric shaft 425 is fixedly connected with a control disc 429.

The air enters the collection box 423 through the communicating pipe 431. When the piston plate 437 moves right, due to the check valve 436 on the air outlet pipe 430, the gas is discharged. Repeating the above process, the suction heads 420 repeatedly suck and collect the dust, avoiding the influence of excessive dust on the physical and mental health of the staff.

Under the action of the connecting frame 409, the lifting block 402 and the lifting plate 403, the lifting plate 403 drives the dispersion plate 406 to move up and down repeatedly, causing the fine coal to vibrate in the vertical direction. At the same time, the runner 410 drives the control block 411 to rotate. Under the action of the first rotating plate 412, the control plate 413, the second rotating plate 416 and the connecting block 417, the dispersion plate 406 is driven to move left and right repeatedly, causing the fine coal material to vibrate in the horizontal direction, facilitating the dispersion operation of the fine coal material, and enabling the fine coal material on the dispersion plate 406 to be evenly fed into the feed hopper of the belt filter press to avoid caking.
