Description

Technical Field

[0001] The utility model belongs to the technical field of gas drainage equipment, and specifically refers to a slag removal device for mine gas drainage. Background Art

[0002] In a mine gas drainage system, to prevent large objects, impurities, water, etc. from entering the drainage pipeline and affecting the drainage negative pressure and damaging the drainage equipment, generally a slag remover and a filter are installed at the connection between the drainage location and the main pipeline. This can effectively block the influence of sundries, water, etc. on the drainage system from the source, thereby maximizing the drainage of mine gas and ensuring the safety and production of the mine.

[0003] However, the existing slag removal device for mine gas drainage uses a filter for cleaning. The filter cannot continuously drain water and remove slag. When there is too much water and coal slag, it is necessary to stop the drainage to carry out the operation of draining water and removing slag. Content of the Utility Model

[0004] In view of the above situation, to overcome the defects of the prior art, the slag removal device for mine gas drainage proposed by the utility model effectively solves the problem that the existing slag removal device for mine gas drainage uses a filter for cleaning, the filter cannot continuously drain water and remove slag, and when there is too much water and coal slag, it is necessary to stop the drainage to carry out the operation of draining water and removing slag.

[0005] The technical solution adopted by the utility model is as follows: The slag removal device for mine gas drainage proposed by the utility model includes a support frame, a filtering structure, and an automatic drainage structure. The filtering structure is arranged on the support frame, the automatic drainage structure is arranged on the filtering structure. The filtering structure includes a filtering tank, a detachable sealing cover, an air outlet nozzle, a partition plate, a filter core, and an air inlet pipe. The filtering tank is fixedly arranged on the support frame, the detachable sealing cover is threadedly arranged above the filtering tank, the air outlet nozzle is fixedly arranged through the upper part of the filtering tank, the partition plate is fixedly arranged in the upper middle part of the filtering tank, the filter core is detachably arranged in the detachable sealing cover, and the air inlet pipe is fixedly arranged through the filtering tank.

[0006] Preferably, the automatic drainage structure includes a drainage hole, a plug, a connecting rod, and a buoyancy ball. The drainage hole is fixedly arranged through the lower part of the support frame, the plug is slidably arranged through the drainage hole, the connecting rod is fixedly arranged above the plug, and the buoyancy ball is fixedly arranged above the connecting rod.

[0007] To better achieve the effect of filtering and cleaning, the filter core is arranged below the air outlet nozzle and above the air inlet pipe.

[0008] To more quickly achieve the purpose of automatic blocking, the plug is arranged in a sealing structure that tightly fits and slides with the drainage hole.

[0009] Furthermore, the drainage hole is arranged in a hollow spherical structure.

[0010] To achieve the effect of automatic drainage, the drainage holes are made of plastic material.

[0011] With the above structure, the beneficial effects of the present utility model are as follows: In the coal mine gas drainage and slag removal device proposed in this solution, by arranging a buoyancy ball inside, when there is too much water, the buoyancy ball floats at this time, pulling the sealing plug on the connecting rod to slide out from the drainage hole, thereby opening the drainage hole. At this time, water and coal slag are discharged from the drainage hole, so as to realize continuous drainage work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the mine gas drainage and slag removal device proposed by the utility model includes a support frame 1, a filtering structure 2 and an automatic drainage structure 3. The filtering structure 2 is arranged on the support frame 1, and the automatic drainage structure 3 is arranged on the filtering structure 2. The filtering structure 2 includes a filtering tank 4, a detachable sealing cover 5, an air outlet nozzle 6, a partition plate 7, a filter element 8 and an air inlet pipe 9. The filtering tank 4 is fixedly arranged on the support frame 1. The detachable sealing cover 5 is threadedly arranged above the filtering tank 4. The air outlet nozzle 6 is fixedly arranged through the upper part of the filtering tank 4. The partition plate 7 is fixedly arranged in the upper middle part of the filtering tank 4. The filter element 8 is detachably arranged in the detachable sealing cover 5. The air inlet pipe 9 is fixedly arranged through the filtering tank 4. The filter element 8 is arranged below the air outlet nozzle 6 and above the air inlet pipe 9.

[0019] As Figure 1 , Figure 2 and Figure 3 shown in the figure, the automatic drainage structure 3 includes a drainage hole 10, a plug 11, a connecting rod 12 and a buoyancy ball 13. The drainage hole 10 is fixedly arranged through the lower part of the support frame 1. The drainage hole 10 is arranged in a hollow spherical structure. The drainage hole 10 is made of plastic material. The plug 11 is slidably arranged through the drainage hole 10. The plug 11 is arranged in a sealing structure that tightly fits with the drainage hole 10 in a sliding manner. The connecting rod 12 is fixedly arranged above the plug 11. The buoyancy ball 13 is fixedly arranged above the connecting rod 12.

[0020] During specific use, when the user uses this device, first connect the air outlet nozzle 6 to the gas drainage pump, and then connect the drainage pipe to the air inlet pipe 9. Control the gas drainage pump to start draining gas. A large amount of coal slag and groundwater in the coal seam will be drained out together. At this time, the gas mixed with coal slag and groundwater first enters the filtering tank 4. At this time, the groundwater and coal slag accumulate in the lower part of the filtering tank 4. At the same time, the coal dust contained in the gas passes through the filter element 8 for filtration. Thus, the clean gas is collected by being drained through the air outlet nozzle 6. When too much water accumulates in the filtering tank 4, at this time, the buoyancy ball 13 is floated by the water. At this time, the buoyancy ball 13 pulls the plug 11 on the connecting rod 12 to slide out of the drainage hole 10. At this time, the coal slag accumulated at the bottom of the filtering tank 4 flows out of the drainage hole 10 along with the accumulated water. After most of the water has flowed out, at this time, the buoyancy ball 13 drops downward with the water level. At this time, the plug 11 slides back into the drainage hole 10 and blocks the drainage hole 10. Thus, the drainage and slag removal are automatically cycled, avoiding frequent disassembly and cleaning. The above is the entire use process of the mine gas drainage and slag removal device.
