[0037] The suction fan 62 in the present utility model is an existing publicly disclosed technology, and the selected model is CF-11.

[0038] The structures and operating principles of the coal washing device body 1, water supply component 2, and screening component 3 in the present utility model have been disclosed in a coal washing device for preventing blockage with a Chinese patent application number of 202321330498.9. Its working principle is as follows: Coal is added, and then water inside the storage tank is pumped by a pump body and injected into the storage tank through a water inlet pipe. The air pressure inside the storage tank is controlled by a breathing valve. At the same time, the water inside the pump body enters the inside of a water guide pipe. The water inside the water guide pipe enters the inside of a conduit and a pipeline respectively. The water in the conduit enters the inside of a first spray disc through a connecting pipe and is sprayed onto the coal on the second elastic screen through a first spray net for cleaning. Also, the water inside the pipeline enters a second spray disc through a fixed pipe, and the second spray net cleans the coal on the first elastic screen. At the same time, the coal blocks are filtered from the second elastic screen to the first elastic screen. The second pneumatic push rod drives the second connecting plate and the second elastic screen to bend and deform, ejecting the coal blocks blocked on the second elastic screen. Also, the large coal blocks filtered by the second elastic screen are discharged through a third outlet. At the same time, the coal falling on the first elastic screen is filtered by the first elastic screen, cleaned by the second spray net, and the first pneumatic push rod drives the first connecting plate and the first elastic screen to move up and down. The first elastic screen bends and deforms, ejecting the coal blocks blocked on the first elastic screen. Then, the coal filtered by the first elastic screen is discharged through a second outlet. The coal powder filtered by the first elastic screen and the second elastic screen falls on an inclined body and is discharged through a first outlet, which can conveniently avoid screen blockage and improve the screening efficiency.

[0039] Working principle and usage process of the present utility model: The present utility model is used for coal washing. During use, coal is added through the feed pipe 5. When adding coal, the flying coal powder is collected and processed by the dust suction component 6. Then, water is supplied to the interior of the device through the water supply component 2. After that, the coal washing is carried out through the cooperation of the coal washing device body 1 and the screening component 3. The waste water from the coal washing is treated by the waste water treatment component 4 and then recycled. When the waste water treatment component 4 is in use, the waste water is discharged into the waste water treatment tank 41, and then a flocculant is added and stirred and flocculated by the stirring component 42. After that, the solenoid valve 43 is opened and the water is discharged into the filter seat 44. After being filtered by the filter screen 46, the water is transported to the water supply component 2 through the water pump 47 and the delivery pipe 48 for continuous use. When the stirring component 42 is in use, the stirring rod 421 is driven to rotate by the stirring motor 423, so as to drive the stirring blade 422 to rotate, and the waste water and the flocculant are stirred and flocculated. The protective cover 424 is convenient for protecting the stirring motor 423, making it convenient to treat the waste water after coal washing during the use of the device, and improving the practicality of use. When the dust suction component 6 is in use, the exhaust fan 62 is started, and the coal powder flying out of the feed pipe 5 during feeding is collected and processed through the dust conveying pipe 63 and the dust collecting hood 64. When it is necessary to process the collected coal powder, the sealing cover 66 is removed, and then the disassembly and assembly box 65 can be pulled out to process the coal powder, making it convenient to collect and process the dust flying out of the feed pipe 5 during feeding during the use of the device, and improving the practicality of use.
