Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of coal mine cleaning, and particularly relates to a coal mine cleaning device. BACKGROUND

[0002] A coal mine is a region where coal resources are mined in a coal-rich mining area, and is usually divided into underground coal mines and open-pit coal mines. During the mining process, part of the coal ash is carried. If the coal ash is not separated from the coal mine during the production process, the purity of the coal mine will be reduced, and the quality of the product will be affected. Therefore, a cleaning device needs to be used in the mining process to clean the coal mine and remove the coal ash on the surface of the coal mine.

[0003] The existing cleaning device is to convey the coal mine to the conveying belt, and the coal mine is cleaned by spraying water during the conveying of the conveying belt. However, the coal mines on the conveying belt are often stacked together, and the spray cleaning can only clean the outer surface of the coal mine stack. The water penetrating into the interior of the coal mine stack is difficult to clean the coal mine in the interior of the coal mine stack, thereby causing the overall cleaning of the coal mine stack to be uneven and the cleaning effect to be poor. SUMMARY

[0004] In view of the problems in the prior art, the present application proposes the following technical scheme:

[0005] A coal mine cleaning device, comprising an outer box body and a water inlet mechanism, the top of the outer box body is connected with a feeding port, and the inside of the outer box body is provided with a conveying belt assembly, and the cleaning device further comprises:

[0006] A cleaning mechanism is penetratingly rotatably connected to the outer box body;

[0007] A driving mechanism is arranged on the front outer wall of the outer box body, and the driving mechanism is used to drive the cleaning mechanism to rotate and spray water;

[0008] A filter screen mechanism comprises an inclined filter screen plate slidingly connected to the inner wall of the outer box body, the cleaning mechanism rotates to spray water, the coal mine above the inclined filter screen plate is cleaned in the first section, the coal mine falling from the end of the inclined filter screen plate is cleaned in the second section, and the water flow is downwardly cleaned in the third section to the coal mine conveyed outward by the conveying belt assembly.

[0009] The coal mine falls to the top of the obliquely arranged filter screen plate from the feeding port to the inside of the outer box body, and moves downward along the slope of the obliquely arranged filter screen plate, and drives the cleaning mechanism to rotate as a whole under the driving of the driving mechanism, and the water feeding mechanism injects water into the cleaning mechanism, so that the cleaning mechanism continuously rotates to spray water outward, and the cleaning mechanism sprays water to clean the coal mine above the obliquely arranged filter screen plate for the first time, and sprays water to clean the coal mine for the second time in the process of falling from the end of the obliquely arranged filter screen plate to the top of the conveying belt assembly, and sprays water to clean the coal mine on the conveying belt assembly for the third time, and the coal mine is cleaned more thoroughly and the cleaning effect is better.

[0010] As a preferred technical scheme of the above, the filter screen mechanism further comprises a fixed strip plate fixedly connected to the inside of the outer box body, and a spring fixedly connected to the top of the fixed strip plate, and the top end of the spring is fixed to the bottom of the obliquely arranged filter screen plate.

[0011] By arranging the fixed strip plate and the spring, the obliquely arranged filter screen plate and the coal mine above the obliquely arranged filter screen plate can be driven to vibrate up and down continuously in the process of the cleaning mechanism spraying water to the obliquely arranged filter screen plate, which is conducive to the downward conveying of the coal mine, and the vibration is also conducive to the flattening of the coal mine above the obliquely arranged filter screen plate, the cleaning effect is better, and the vibration can also avoid the residues of the coal mine from blocking the leakage holes of the obliquely arranged filter screen plate.

[0012] As a preferred technical scheme of the above, the filter screen mechanism further comprises a guide plate fixedly connected to the top of the obliquely arranged filter screen plate and a vertical filter screen plate fixedly connected to the inside of the outer box body.

[0013] The guide plate can guide the coal mine above the obliquely arranged filter screen plate to drop from the end of the obliquely arranged filter screen plate to the top of the conveying belt assembly, and not to the interval between the conveying belt assembly and the inner wall of the front and back of the outer box body, and the vertical filter screen plate can avoid the coal mine from being washed to the gap between the conveying belt assembly and the inner left wall of the outer box body under the action of the rotating water of the cleaning mechanism, so that the coal mine can fall to the top of the conveying belt assembly to be conveyed, and the dirty water after the coal mine is washed can pass through the vertical filter screen plate to fall to the gap between the conveying belt assembly and the inner left wall of the outer box body, so as to avoid the dirty water from falling to the coal mine above the conveying belt assembly to cause secondary pollution.

[0014] As the preferred of the above technical scheme, the cleaning mechanism comprises a main cylinder pipe, a plurality of fixed ring strips are fixedly connected to the periphery of the main cylinder pipe, a plurality of shunt pipes arranged along the periphery of the main cylinder pipe are fixedly connected to the plurality of fixed ring strips, a plurality of spray heads are interconnected on the outer wall of the shunt pipe, and a reinforcing band is arranged on the periphery of the shunt pipe.

[0015] As the preferred of the above technical scheme, the two sides of the main cylinder pipe are fixedly connected with mounting ring plates, and the main cylinder pipe is rotatably inserted into the outer wall of the outer box body. The two mounting ring plates are fixedly connected with transmission columns away from each other. A plurality of water holes are formed in the transmission columns, and the water holes are in communication with the shunt pipes.

[0016] Through the water inlet mechanism, water is injected into the cleaning mechanism. The water enters the inside of the shunt pipe through the water holes, and then is evenly sprayed from the plurality of spray heads through the shunt of the shunt pipe. The fixed ring strips are arranged to fixedly install the shunt pipes on the periphery of the main cylinder pipe, and the reinforcing band is arranged to further reinforce the installation firmness of the shunt pipes.

[0017] As the preferred of the above technical scheme, the driving mechanism comprises a motor carrier fixedly connected to the front face of the outer box body, a motor is mounted on the top of the motor carrier, and a rotating shaft is fixedly connected to the output shaft of the motor. The rotating shaft is drivingly connected with the transmission column through a belt pulley assembly.

[0018] The working principle of the driving mechanism is that the motor drives the rotating shaft to rotate, and the rotating shaft drives the transmission column to rotate under the transmission of the belt pulley assembly.

[0019] As the preferred of the above technical scheme, the water inlet mechanism comprises an outer cover disc fixedly connected to the outside of the transmission column. The outer cover disc is sealingly rotatably inserted with a water inlet pipe.

[0020] The water inlet pipe is connected with the external water supply mechanism. The water supply mechanism supplies water to the inside of the outer cover disc through the water inlet pipe, and then enters the water holes in the inside of the transmission column. Since the outer cover disc and the outer side wall of the transmission column are fixedly connected, the outer cover disc will rotate synchronously with the transmission column. The water inlet pipe is sealingly rotatably inserted into the outer side of the outer cover disc, which can ensure that the water inlet pipe can send water without moving. The sealingly rotatably inserted component is preferably a sealing bearing.

[0021] As the preferred of the above technical scheme, the lower part of the cleaning mechanism is provided with a flow guide mechanism. The flow guide mechanism comprises a flow guide inclined plate located below the cleaning mechanism. The two sides of the flow guide inclined plate are fixedly connected with side baffles. The outer wall of the side baffle is fixedly connected with a connecting column. The side away from the side baffle of the connecting column is fixedly connected with the inner wall of the outer box body.

[0022] After the cleaning mechanism rotates to spray water through the obliquely arranged filter screen plate to clean the coal above, the dirty water will fall downward through the obliquely arranged filter screen plate under the action of gravity, and then fall onto the flow guide inclined plate. Under the side blocking of the side baffle and the slope of the flow guide inclined plate, the dirty water flows to the interval area between the front inner wall and the back inner wall of the conveying belt assembly and the outer box body, thereby avoiding the dirty water flowing into the coal above the conveying belt assembly, and thereby avoiding secondary pollution.

[0023] The present application has the following advantages:

[0024] 1. The coal is put into the outer box body from the feeding port and falls onto the top of the obliquely arranged filter screen plate, and moves downward along the slope of the obliquely arranged filter screen plate. Meanwhile, the cleaning mechanism is driven to rotate as a whole under the driving of the driving mechanism, and the water inlet mechanism injects water into the cleaning mechanism, so that the cleaning mechanism continuously rotates to spray water outward. The cleaning mechanism rotates to spray water through the obliquely arranged filter screen plate to clean the coal above for the first time. In the process that the coal falls from the end of the obliquely arranged filter screen plate to the top of the conveying belt assembly, the cleaning mechanism rotates to spray water for the second time. When the coal falls onto the conveying belt assembly, the cleaning mechanism rotates to spray water to the right inner wall of the outer box body first, and then flows downward along the right inner wall, and then cleans the conveyed coal on the conveying belt assembly for the third time. Through the three times of cleaning, the coal is cleaned more thoroughly, and the cleaning effect is better.

[0025] 2. By arranging the fixed baffle and the spring, in the process that the cleaning mechanism rotates to spray water to the obliquely arranged filter screen plate, the spring can drive the obliquely arranged filter screen plate and the coal above to vibrate up and down continuously. This is not only beneficial to the downward conveying of the coal, but also beneficial to the flattening of the coal above the obliquely arranged filter screen plate, and the cleaning effect is better. In addition, the vibration can also avoid the residues of the coal from blocking the leakage holes of the obliquely arranged filter screen plate. BRIEF DESCRIPTION OF DRAWINGS
