The application discloses a coal block crusher cleaning device, relates to the technical field of coal mine production, and improves the problems that if the effective interval adjustment of the brush plate is difficult, on one hand, it is difficult to maintain stable cleaning strength only by intermittent extrusion force, leading to incomplete cleaning of coal cinder, on the other hand, the coal cinder that is not cleaned in time can be mixed into a subsequent processing flow, affecting the quality of coal products, reducing the market competitiveness of products and the like, and comprises a box body, the cleaning mechanism comprises an electric cylinder and a push plate, and the other side surface of the push plate is fixedly provided with brush strips and spraying pipes respectively, the application can stably move the push plate installed at the output end through the cleaning mechanism, the brush strips and the spraying pipes connected with the push plate follow synchronously, through the linkage design, the brush strips and the spraying pipes can be accurately close to the crushing mechanism, efficient cleaning and flushing of residual materials on the surface of the crushing equipment are realized, and the cleaning effect is obviously improved.

This invention proposes a process for separating and dewatering lump coal, belonging to the field of coal washing technology. A plasma reactor is used to ionize and activate flocculant solution 1 to form flocculant solution 2. The ionized and activated flocculant solution 2 is then sprayed onto the lump coal using a venturi tube. Subsequently, a plasma spray gun is used to emit plasma onto the lump coal sprayed with flocculant solution 2, thereby modifying the surface of the coal lump coated with flocculant solution 2 to form a solidified hydrophobic film. The lump coal with the solidified hydrophobic film is then separated to separate gangue from the lump coal, obtaining the final product. This effectively improves the hydrophobicity and brittleness of the lump coal, ultimately improving the dewatering effect of the lump coal.

This invention discloses a coal briquetting and screening device for coal preparation, relating to the field of coal briquetting and screening technology. It includes a housing with support frames fixedly installed on both sides for securing the entire device. A briquetting component is housed inside the housing, and a dust treatment component is located at the back of the housing. The front of the dust treatment component is fixedly connected to the rear of the briquetting component, and a feeding component is fixedly installed on the top of the housing. Through the housing, support frames, briquetting component, and dust treatment component, the rotating disc causes the connecting column to slide inside the anti-rotation ring, thereby pushing the anti-rotation ring up and down. The anti-rotation ring then drives the sliding rod to slide up and down on the connecting frame, causing the fiberboard to rub against the inside of the plastic plate, adsorbing the dust generated during crushing onto the surface. This allows the device to automatically adsorb the dust generated while crushing coal, preventing dust from spreading and achieving the effect of protecting the environment and worker health.

The present application relates to a kind of coal tower suspension material cleaning equipment;Including positioning disc;The bottom of the positioning disc is fixedly connected with connecting pipe, the top of the connecting pipe is connected with water inlet pipe, the bottom of the positioning disc is provided with positioning groove, the inner side wall of the positioning groove is rotatably connected with driving wheel by positioning rod;The present application is positioned by the setting of positioning disc and driving wheel, so that driving wheel is attached to the inner wall of coal tower, ensure the stability of positioning disc in the lifting process in coal tower, to position connecting pipe, positioning disc enters coal tower, start pump water machine and pump into water to cleaning pipe, water is sprayed by nozzle and is impacted to the inner wall of coal tower, the broken blade of the bottom of connecting pipe rotates, broken blade is cut and broken to the coal block accumulated before high-pressure spray gun is cleaned to the inner wall of coal tower, avoid freezing due to temperature too low, at this time, high-pressure spray gun is more difficult to spray and clean coal block or cleaning time is longer.

The utility model relates to the technical field of coal washing, in particular to a coal medium distributing and screening device which comprises a top shell arranged in a pump pit. The inner side of the top of the top shell is bolted with a grate plate; the bottom surface of the top shell is in bolted connection with a filter cartridge shell; the bottom of the inner ring of the filter cartridge shell is bolted with a filter plate; a mounting column is mounted in the middle of the filter plate in a threaded manner; a push strip is arranged at the top of the mounting column in a surrounding manner; a first motor is fixedly connected to the bottom of the mounting column. A coal slime outlet pipe is arranged on the outer side of the filter cartridge shell; coal briquettes with large volumes in the filter medium are intercepted by the grate plate, and coal briquettes with small volumes are filtered and intercepted by the filter plate and are gathered on the top surface of the filter plate; the push strip is attached to the top surface of the filter plate to rotate, so that coal briquettes are discharged from a coal slime outlet pipe on the outer ring of the filter cartridge shell; therefore, the filtering, separating and recycling work of the medium rushing into the pump pit is realized, the recycling rate of the medium is further improved, and the economic loss is reduced.
