A feed inlet 41 communicated with the feed channel 2 is formed in the right side of the vertical cylinder 4, the inner width of the feed inlet 41 is equal to that of the feed channel 2, and the position of the feed inlet 41 is higher than that of the conveyor 1.

Thus, after entering the feed hopper 5, the coal mine falls with it onto the separation plate 8 and then through the feed channel 2 onto the conveyor 1.

Circulating dust fall mechanism is equipped with shower nozzle 10 including fixing the protecting frame 9 on feeder hopper 5 outside top in the inboard of protecting frame 9, and shower nozzle 10 bottom is equipped with bleeder 11, and bleeder 11 bottom is equipped with shunt tubes 12, and the one end of shunt tubes 12 is equipped with raceway 13, and the water pump 14 on base plate 3 is settled to the raceway 13 other end, and upright 4 surfaces are equipped with the inlet tube 18 that extends to upright 4 insides.

Clean water is pumped by a water pump 14 and flows into the shunt pipe 12, and then flows into the spray head 10 through the shunt pipe 11 to spray water mist, so that the aim of dust fall is fulfilled.

Wherein, the number of the nozzles 10 is 4, and the 4 nozzles 10 are respectively arranged at the central positions on the 4 side walls of the protective frame 9, the spraying directions of the nozzles 10 form an included angle of 45 degrees with the horizontal line, and the spraying directions of the 4 nozzles 10 are all towards the center of the feed hopper 5.

The water mist sprayed from 4 directions can fully cover the space above the whole feed hopper 5, so that the aim of dust fall is fulfilled as far as possible.

It should be noted that the separating plate 8 includes a plate 81 fixed on the top of the hydraulic damper 7, a plurality of water leaking holes 82 vertically penetrating the plate 81 are formed on the plate 81 at equal intervals, and a speed reducing bar 83 is fixedly mounted on the top surface of the plate 81 and at the side of the water leaking holes 82.

After the coal mine and the water are mixed together, the water can directly penetrate through the water leakage hole groove 82, so that solid-liquid separation is realized, the speed of falling of the coal mine can be reduced by the speed reducing strips 83, and the time of solid-liquid separation is longer and more thorough.

And, one end of plate 81 passes through feed inlet 41 and extends to the inside of feedstock channel 2, can guarantee that the colliery gets into in feedstock channel 2.

The input end of the water pump 14 is provided with a pipeline extending to the inside of the vertical cylinder 4, the other end of the pipeline is provided with a filter cover, and the inner wall of the vertical cylinder 4 is provided with a filtering component 15 below the supporting seat 6 for filtering sewage penetrating through the separating plate 8. A cleaning door 16 corresponding to the filter assembly 15 is hinged on the front surface of the upright barrel 4, and the cleaning door 16 can be opened periodically to take out the filter assembly 15 for cleaning or replacement.

A water level switch is arranged on the inner wall of the vertical cylinder 4 and below the filtering component 15 for detecting the water level in the vertical cylinder 4 in real time. The surface of the water inlet pipe 18 is provided with an electronic water valve 19 electrically connected with the water level switch 17.

Referring to fig. 4, the water level switch 17 includes a support plate 171 disposed on the inner wall of the vertical tube 4, a vertical rod 172 is disposed at the bottom of the support plate 171, a limit plate 173 is disposed at the bottom end of the vertical rod 172, a trigger switch 174 is disposed at one side of the limit plate 173 opposite to the support plate 171, a floating plate 175 is slidably mounted on the surface of the vertical rod 172, and a controller 176 is disposed at the top of the support plate 171.

When the water level rises, the floating plate 175 moves upwards along with the water level rise until the floating plate 175 contacts the top trigger switch 174, at which time, the controller 176 closes the electronic water valve 19 to stop the water injection, and when the water level falls, the floating plate 175 moves downwards along with the water level rise until the floating plate 175 contacts the bottom trigger switch 174, at which time, the controller 176 opens the electronic water valve 19 to start the water injection.

The working principle is as follows: when a coal mine enters the vertical barrel 4 through the receiving hopper 5, water is pumped by the water pump 14 and is injected into the flow dividing pipe 12, then water is divided into 4 strands by the 4 branch pipes 11, the water is sprayed out to the center of the receiving hopper 5 at an upward 45-degree angle through the 4 spray nozzles 10, after the water mist is contacted with the dust, large particles are rapidly formed and fall into the vertical barrel 4, the dust is reduced by the water mist, after the coal mine enters the vertical barrel 4, the coal mine falls onto the separating plate 8, then the coal mine automatically rolls into the feeding channel 2 under the action of gravity until the coal mine enters the conveyor 1 for conveying, in the process, the coal mine passes through the separating plate 8, the double buffering and speed reduction of the feeding channel 2, so that the impact of the coal mine on the conveyor 1 is reduced, meanwhile, when the coal mine falls onto the separating plate 8, the hydraulic shock absorber 7 performs buffering, the impact on the separating plate 8 is reduced, when the water mist and the coal mine fall onto the separating plate 8, liquid falls into the bottom space of the vertical barrel 4 through the water leakage hole grooves 82, the solid-liquid separation is realized, and liquid impact of the coal mine is further reduced through the speed reduction strips 83, and the solid-liquid impact of the coal mine is reduced more thoroughly. After the sewage passes through the water leakage hole groove 82, the sewage is filtered by the filtering component 15, the sewage is purified and then is supplied to the water pump 14 for dust fall, the water level switch 17 monitors the water quantity in real time, when the water quantity is lower than the lowest critical value, the electronic water valve 19 is controlled to be opened, the water inlet pipe 18 continues to inject clean water, and after the water level reaches the highest critical value, the electronic water valve 19 is closed, and then water injection is stopped.
