[0045] The coal transport and cooling device of the embodiment of the present invention comprises a water tank 1, a vibration frame 2, a support frame 3, a coal washing barrel 4, a vibration driving component 5, a spray assembly 6 and a cooling circulation component.

[0046] The vibration frame 2 can be set on the inner wall surface of the water tank 1 for reciprocating vibration, the support frame 3 is fixed on the water tank 1, and there is a gap between the support frame 3 and the vibration frame 2 to prevent the two from interfering with each other during vibration; the coal washing barrel 4 can be rotatably set on the vibration frame 2; the vibration driving member 5 includes an eccentric shaft 51 and a matching shaft 52, one of the eccentric shaft 51 and the matching shaft 52 is set on the vibration frame 2, and the other of the eccentric shaft 51 and the matching shaft 52 is set on the support frame 3, and the eccentric shaft 51 and the matching shaft 52 are rotatably matched, so that the relative position of the vibration frame 2 and the water tank 1 can be adjusted by the rotational matching of the eccentric shaft 51; the nozzle 63 of the spray assembly 6 is arranged opposite to the coal washing barrel 4 so that the spray assembly 6 sprays and cools down the raw coal in the coal washing barrel 4, and the cooling circulation member is used to circulate the spray water in the cooling water tank 1.

[0047] The coal transport and cooling device of the embodiment of the present invention can rotatably set the coal washing cylinder 4 on the vibration frame 2, and the spray assembly 6 can spray and cool the raw coal in all directions, thereby avoiding the problem of incomplete cooling caused by too thick coal seams during transportation. Therefore, the coal transport and cooling device has the advantage of good cooling effect, thereby improving the safety during transportation.

[0048] In addition, by dividing the vibration drive member 5 into an eccentric shaft 51 and a matching shaft 52, one of the eccentric shaft 51 and the matching shaft 52 is arranged on the vibration frame 2, and the other of the eccentric shaft 51 and the matching shaft 52 is arranged on the support frame 3, the eccentric shaft 51 rotates accordingly, and the eccentric shaft 51 continuously pushes the entire mobile frame to vibrate back and forth with the help of the contact force of the matching shaft 52, so that the mobile frame vibrates up and down, and the coal slag is vibrated and stirred. Then, the coal powder can be dropped into the water tank 1, which helps to reduce the floating of coal dust during transportation (when the coal dust is mixed with air to a certain concentration, it may explode when encountering a fire source or high temperature), thereby helping to further improve the safety during transportation.

[0049] Therefore, the coal transportation and cooling device of the coal mine according to the embodiment of the present invention has the advantage of improving transportation safety.

[0050] Optionally, the inner wall surface of the water tank 1 has one of the guide rail and the guide groove, and the vibration frame 2 has the other of the guide rail and the guide groove.

Then the transmission of the coal washing barrel 4 and the eccentric shaft 51 is realized. Therefore, the coal transport and cooling device of the coal mine realizes synchronous vibration during the rotation process, prevents the broken coal from forming water-retaining groups, and prevents the spray water from contacting with the coal blocks to affect the cooling effect of the coal seam. Therefore, the coal transport and cooling device of the coal mine further improves the advantage of uniformity of cooling.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, the coal transportation and cooling device of the coal mine embodiment of the present invention also includes a feed hopper 8, one end of which extends from the feed port of the coal washing tube 4 into the interior of the coal washing tube 4, and the feed hopper 8 and the coal washing tube 4 are gap-matched, and the coal washing tube 4 and the feed hopper 8 are sealed and connected by a buffer soft belt, and the feed hopper 8 is fixed on the water tank 1 through a support plate 13.

[0057] The coal transport and cooling device for coal mines of the embodiment of the present invention can transport raw coal from the feed hopper 8 to the coal washing barrel 4 through the feed hopper 8, which helps to improve the feeding rate. The coal washing barrel 4 and the feed hopper 8 are sealed and connected by a buffer soft belt, which helps to reduce the overflow of coal powder and further reduce the generation of coal dust.

[0058] Optionally, the feed hopper 8 can be a straight cylindrical structure, and the upper part is a bucket-shaped structure. In other embodiments, the feed hopper 8 can also be bent or obliquely arranged.

Therefore, the coal transport and cooling device of the coal mine helps to realize the continuity of the operation of the device.

[0061] Furthermore, the aperture of the mesh holes of the filter cylinder 9 is smaller than the aperture of the coal washing cylinder 4 .

[0062] Optionally, in another solution, a sedimentation tank may be provided at the bottom of the coal washing cylinder 4, so that the precipitated coal dust will fall into the sedimentation tank, thereby omitting the design of the filter cylinder 9.

[0064] like Figure 2 and Figure 3 As shown, the coal transport and cooling device of the embodiment of the present invention further includes a reset member 11, one end of which is fixed on the water tank 1, and the other end of which is fixed on the vibration frame 2 so as to reset the vibration frame 2 when the vibration frame 2 vibrates, and the reset member 11 can achieve a shaking function when resetting. Thus, the coal transport and cooling device of the coal mine further improves the cooling effect.

[0065] The coal transport and cooling device for coal mines of the embodiment of the present invention can cooperate with the rotation of the eccentric shaft 51 by providing the reset member 11, so that the vibration frame 2 can reciprocate in the direction, which is beneficial to improving the cooling effect.

[0066] Optionally, the other end of the reset member 11 is fixed to the side wall surface of the vibration frame 2 , thereby facilitating the installation and positioning of the reset member 11 .

[0068] like Figure 2 and Figure 3 As shown, the reset member 11 includes a base plate 111, a guide column 112, an elastic compression spring 113 and a connecting plate 114. The base plate 111 is fixed on the water tank 1, the elastic compression spring 113 is sleeved on the guide column 112, and the two ends of the elastic compression spring 113 are respectively abutted against the base plate 111 and the connecting plate 114, the guide column 112 is fixed on the base plate 111, the connecting plate 114 is connected to the vibration frame 2, and the connecting plate 114 can be slidably passed through the guide column 112.

[0069] The coal transport and cooling device of the embodiment of the present invention is provided by dividing the reset member 11 into a base plate 111, a guide column 112, an elastic compression spring 113 and a connecting plate 114, and fixing the guide column 112 on the base plate 111, connecting plate 114 on the vibration frame 2, and connecting plate 114 is slidably inserted on the guide column 112. Therefore, the coal transport and cooling device has the advantage of good structural stability.

[0070] like Figure 2 , Figure 4 and Fig. 9 As shown, the spray assembly 6 includes a water pressure pump 61 , a liquid guide pipe 62 and a plurality of nozzles 63 . The liquid guide pipe 62 extends along the axial direction of the coal washing barrel 4 . The plurality of nozzles 63 are arranged on the liquid guide pipe 62 at intervals along the axial direction of the coal washing barrel 4 .

[0071] The coal transport and cooling device of the embodiment of the present invention is provided by dividing the spray assembly 6 into a water pressure pump 61, a liquid guide pipe 62 and a plurality of nozzles 63, wherein the plurality of nozzles 63 are arranged on the liquid guide pipe 62 at intervals along the axial direction of the coal washing barrel 4 to continuously spray water. Therefore, the coal transport and cooling device has the advantage of good cooling performance.

[0072] like Figure 2 , Figure 4 and Fig. 9As shown, the water pressure pump 61 includes a pressure cylinder 611, a piston 612, a sliding rod 613, a force plate 614 and a return spring 615. The piston 612 is reciprocatingly arranged in the pressure cylinder 611 so as to divide the pressure cylinder 611 into a first cavity and a second cavity arranged in parallel. The first cavity is provided with a first inlet pipe and a first outlet pipe connected thereto on the outside, a first one-way inlet valve is installed inside the first inlet pipe, a first one-way outlet valve is installed inside the first outlet pipe, and a second inlet pipe and a second outlet pipe connected thereto on the outside of the second cavity are provided with a second one-way outlet valve on the inside of the first inlet pipe. Tube, a second one-way inlet valve is installed inside the second inlet tube, a second one-way outlet valve is installed inside the second outlet tube, a sliding hole is opened on the top of the pressure cylinder 611, a sliding rod 613 is sealed and slidably arranged in the sliding hole, two ends of the sliding rod 613 are respectively connected to the force plate 614 and the piston 612, a return spring 615 is sleeved on the sliding rod 613, two ends of the return spring 615 are respectively abutted against the force plate 614 and the piston 612, the force plate 614 is abutted against the bottom of the vibration frame 2 to provide driving force for the force plate 614 through the vibration frame 2.

[0073] Specifically, each branch of the liquid guide tube 62 is equipped with a nozzle 63 connected thereto, and the water spray of the nozzle 63 is set toward the coal washing cylinder 4, and the two ends of the vibration frame 2 and the filter cylinder 9 are respectively rotatably mounted on the vibration frame 2. During the vibration of the vibration frame 2, the lower end of the vibration frame 2 will squeeze the force plate 614. After the pressure plate is stressed, the sliding rod 613 will drive the piston 612 to move back and forth along the axial direction of the pressure cylinder 611, thereby changing the size and pressure of the first cavity and the second cavity. Under the change of the size and pressure of the first one-way inlet valve, the first one-way outlet valve and the first cavity, the water is pressed to the nozzle 63 end in the spray assembly 6 to realize the spray cooling of the raw coal. Similarly, under the action of the reset spring 615, the size and pressure of the second cavity will be changed. Under the change of the size and pressure of the second one-way inlet valve, the second one-way outlet valve and the second cavity, the spray cooling of the raw coal can also be realized. That is, while the vibration frame 2 is vibrating, the water pressure pump 61 can continuously provide the spray assembly 6 with the power of spraying. For example, when the sliding rod 613 and the piston 612 move downward, negative pressure is generated in the first cavity, water enters the first cavity from the first one-way inlet valve, and water in the second cavity enters the liquid guide tube 62 and the plurality of nozzles 63 from the second one-way outlet valve. Conversely, water enters the second cavity from the second one-way inlet valve, and water in the first cavity enters the liquid guide tube 62 and the plurality of nozzles 63 from the first one-way outlet valve. It can be seen from this that the nozzle 63 can continuously spray water, and waste water can be recycled to avoid waste.
