[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally, underground roadways are dug to extract coal, which is an underground coal mine. When the coal seam is very close to the surface, generally, the surface soil layer is directly stripped to excavate coal, which is a surface coal mine. Most coal mines in China belong to underground coal mines. The scope of a coal mine includes a large area above and below the ground and related facilities. A coal mine is a reasonable space excavated by humans when digging a coal-rich geological layer, usually including roadways, shafts, and mining faces, etc. Coal is the most important solid fuel and a type of combustible organic rock. It is formed by lush plants growing in a certain geological era, gradually accumulating into thick layers in a suitable geological environment, and being buried under water or sediment, and undergoing natural coalification over a long geological era. With the increasing development of coal mine exploitation and production.

[0003] At present, in the fully mechanized caving face of industrial coal mines, coal is usually transported by a shearer for coal cutting, a scraper conveyor, a lapping transfer machine, a conveyor, and a belt conveyor. During the coal cutting in the fully mechanized mining face production, spray must be used for dust reduction at each transfer point. Due to the long-term use of the spray and the poor quality of the spray water, the dust-proof spray heads will be blocked. The only way to deal with it is to replace the spray heads, resulting in the consumption of materials and manpower. Content of the Utility Model

Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: a water filtration device for a fully mechanized mining face, including a first main pipe 2. A second main pipe 4 is arranged on one side of the first main pipe 2. A filter screen 3 is arranged near the joint port of the first main pipe 2 and the second main pipe 4, which can effectively filter impurities in water and prevent the nozzle from being blocked. Moreover, this device is simple to process, has extremely low production costs, is also very simple to install, has good use effects, and plays a very good filtering role. A motor 10 is embedded at the central position of the filter screen 3. A cleaning plate 8 is vertically arranged at the output end of the motor 10. A cleaning brush 9 is arranged on the surface of one side of the cleaning plate 8 relative to the filter screen 3. The motor 10 can be started to drive the cleaning plate 8 to rotate in real time, and the cleaning brush 9 is driven to rotate in real time through the cleaning plate 8 to brush the pollutants attached to the inner wall surface of the filter screen 3, avoiding the problem of blockage caused by long-term dense attachment of pollutants. A positioning block 14 is arranged around the outer edge surface of one side of the filter screen 3. A positioning stud 12 is movably arranged through the thread on the surface of the positioning block 14. Bearings 15 are rotatably arranged at the outer ends of the positioning studs 12. The outer rings of the bearings 15 are rotatably arranged with positioning seats 16. By manually twisting the positioning studs 12 to be threadedly engaged on the surface of the positioning block 14, the lifting adjustment is realized through the friction force generated by the thread, so that the fastening tips 11 on the outer end surface of the positioning seat 16 can be in real-time contact and clamping with the inner wall of the pipe, realizing the real-time installation and limitation of the filter screen. An adjusting knob 13 is arranged at one end of the positioning stud 12, which is convenient for manual holding and twisting for telescopic adjustment, making the overall operation more convenient and labor-saving.

[0020] On the outer surface of the positioning seat 16, fastening convex tips 11 are arranged in a circumferential layout. The fastening convex tips 11 are in the shape of a cylinder at the inner end and a sharp cone at the outer end, which can increase the contact friction between the positioning seat 16 and the inner wall of the pipe, making the installation and limit stability of the filter net 3 better. At the outer end of the first main pipeline 2, a water inlet 1 is integrally formed, and at the outer end of the second main pipeline 4, a water outlet 5 is integrally formed, which can conduct real-time import and export of water flow to achieve smooth flow of the whole pipeline. At one side port of the second main pipeline 4, a connector 6 is provided, and on the outer surface of the connector 6 and the inner surface of the port of the first main pipeline 2, twisting threads 7 are provided, which can limit and fix the pipeline main body together in real time through the friction of the threads, avoiding the problem of automatic falling off and separation during long-term use, resulting in leakage of the pipe body.

[0021] Working principle: When spray dust suppression work needs to be carried out, first, the filter net 3 and waste steel pipes can be used to compare and design the size of the filter according to the accumulation position of the water outlet pipe. By combining the filter principle and the convenience of the filter net 3, the two are rotated and screwed together for preliminary preparation. Two sections are processed in advance on the ground using waste steel pipes. One section is processed with threaded and threaded ports, connectors, and two 25 straight-throughs are welded. The grounding electrode shield of the mine is used as the frame, and cotton gauze and the filter screen are combined and fixed together to process and manufacture a set of spray water filtration devices with water connected at both ends to achieve the water filtration effect. By manually twisting the positioning stud 12 to twist and combine on the surface thread of the positioning block 14, the lifting adjustment is achieved through the friction generated by the thread, so that the fastening convex tip 11 on the outer surface of the positioning seat 16 can be in contact and clamped with the inner wall of the pipe in real time, realizing the real-time installation and limit of the filter net. During long-term use, the motor 10 can be started to drive the cleaning plate 8 to rotate in real time, and the cleaning brush 9 is driven to rotate in real time by the cleaning plate 8 to brush the pollutants attached to the inner wall surface of the filter net 3, avoiding the problem of blockage caused by long-term dense attachment of pollutants.
