In the description of the present utility model, unless otherwise specified, "multiple" means more than two.

[0029] In one embodiment of the present invention, Figure 1-5As shown, a blockage-resistant coal suction assembly comprises an outer tube 1, an inner tube 2 and a coal shoveling pipe 3; the outer tube 1 is sleeved on the outer periphery of the inner tube 2, the outer tube 1 is provided with a water inlet hole 11, the water inlet hole 11 is connected to the outer periphery of the inner tube 2, the inner tube 2 is used to allow water on the outer periphery of the inner tube 2 to penetrate into the interior of the inner tube 2, and the interior of the inner tube 2 is connected to the interior of the coal shoveling pipe 3. In this embodiment, the inner tube 2 is made of porous material, and the porous material includes but is not limited to porous metal materials of powder metallurgy and porous ceramics of powder sintering. The bottom of the inner tube 2 is connected to the coal shoveling pipe 3. Specifically, the coal shoveling pipe 3 is sleeved on the bottom of the outer tube 1, so that the interior of the inner tube 2 is connected to the interior of the coal shoveling pipe 3. The top of the inner tube 2 is connected to an external negative pressure device to provide negative pressure for coal suction. The outer tube 1 is sleeved on the outer periphery of the inner tube 2, so that the water inlet 11 of the outer tube 1 can be connected to the outer periphery of the inner tube 2. When working, the negative pressure device starts to work and provides negative pressure, and injects high-pressure water into the water inlet 11 of the outer tube 1. The high-pressure water penetrates into the interior of the inner tube 2 from the outer periphery. Specifically, a water film will be formed on the inner wall of the inner tube 2. When the coal shoveling pipe 3 scoops up the coal slag in the car, under the action of negative pressure, the coal slag is sucked from the bottom of the inner tube 2 to the top of the inner tube 2, and then the coal slag is transferred to other equipment from the top of the inner tube 2. Further, under the action of the water film formed on the inner wall of the inner tube 2, the coal slag will not adhere to the inner wall of the inner tube 2, thereby preventing the coal slag from adhering to the inner wall of the inner tube 2 for a long time and clogging the coal suction component, and the water in the water film moves upward with the coal slag under the action of negative pressure and will not fall. The present application uses the outer tube 1, the water inlet 11, the inner tube 2 and the coal shoveling pipe 3 to form a water film of high-pressure water on the inner wall of the inner tube 2, thereby preventing the coal slag from adhering to the inner wall of the inner tube 2 for a long time and clogging the coal suction component, thereby achieving the effect of improving the working stability and working efficiency of the coal suction component.

[0030] like Figure 2-3As shown, it also includes a sealing partition 4; a plurality of the sealing partitions 4 are installed between the outer tube 1 and the inner tube 2, and the plurality of sealing partitions 4 are evenly arranged along the length direction of the inner tube 2, and a high-pressure water cavity 401 is provided between two adjacent sealing partitions 4 above and below, and the water inlet hole 11 is connected to the outer periphery of the inner tube 2 through the high-pressure water cavity 401. In this embodiment, multiple sealing partitions 4 are respectively installed on the outer periphery of the inner tube 2, and the outer tube 1 is sleeved on the outer periphery of multiple sealing partitions 4, that is, multiple sealing partitions 4 are arranged between the outer tube 1 and the inner tube 2, and the number of the sealing partitions 4 is six. The six sealing partitions 4 divide the area between the outer tube 1 and the inner tube 2 into five high-pressure water chambers 401, and each of the high-pressure water chambers 401 is respectively provided with a corresponding water inlet hole 11. During operation, water is injected into the high-pressure water chamber 401 through the water inlet hole 11, and then the water in the high-pressure water chamber 401 penetrates into the inner wall of the inner tube 2 from the outer periphery of the inner tube 2, thereby forming a water film, and dividing the area between the outer tube 1 and the inner tube 2 into multiple cavities, which can increase the water pressure in the high-pressure cavity 41, so that the water on the outer periphery of the inner tube 2 has sufficient pressure to penetrate into the inner wall of the inner tube 2.

[0031] like Figure 3 As shown, the sealing partition 4 is provided with a first placement groove 41 and a second placement groove 42; the first placement groove 41 is located above the second placement groove 42, the first placement groove 41 faces the outer periphery of the inner tube 2, and the second placement groove 42 faces the inner wall of the outer tube 1, and the second placement groove 42 and the first placement groove 41 are respectively used to place a sealing ring.

The bent pipe can make the coal slag be thrown into the silo along the pipeline from the vertical direction to the horizontal movement direction, reduce the coal material inhaled into the filter tank and reduce the pressure loss along the process, and play a guiding role in throwing.

[0034] like Figure 1-2 As shown, the end of the curved pipe 33 is provided with shovel teeth 331. In this embodiment, the shovel teeth 331 are provided at the end of the curved pipe 33, so that the coal slag stuck on the floor of the carriage can be easily shoveled, and the coal slag is prevented from being firmly stuck to the inner bottom surface of the carriage and cannot be sucked up, thereby achieving the effect of improving the working efficiency of the coal shoveling pipe 3.
