[0026] In one embodiment, a fixed frame 5 is provided on one side of the screw compressor body 1, and the fixed frame 5 facilitates the effective fixing of the internal structure; a rectangular hole is provided on the top of the fixed frame 5, and the internal structure performs subsequent vertical displacement work; a No. 3 connecting plate 6 is welded on one side of the fixed frame 5, and the No. 3 connecting plate 6 serves to connect the structures; and a horizontal through hole is provided in the center of the No. 3 connecting plate 6 to facilitate the circulation of gas; a No. 2 pipe 7 is welded on one side of the No. 3 connecting plate 6 to facilitate the connection between the structures.

[0027] In one embodiment, a vertically movable sealing plate 8 is provided inside the rectangular hole at the top of the fixed frame 5, and the sealing plate 8 facilitates the effective sealing of the structure below; and sealing rings are bonded around the sealing plate 8 to improve the sealing efficiency; a handle 9 is welded on the top of the sealing plate 8 to facilitate the operator to hold it for subsequent lifting work.

[0028] In one embodiment, fixed blocks 10 are vertically welded on both sides of the fixed frame 5, and holes are provided on one side and the top of the fixed block 10, so that the fixed block 10 facilitates the stable rotation of the internal structure; an "L"-shaped limit block 11 is rotatably connected inside the hole of the fixed block 10, and the "L"-shaped limit block 11 is provided on both sides above the sealing plate 8, and when the "L"-shaped limit block 11 rotates, it is convenient to effectively limit and fix the structure below.

[0029] In one embodiment, a drive motor 12 is bolted to one side of the fixed frame 5, and the drive motor 12 is convenient for driving the structure on the output end to rotate. The output end of the drive motor 12 is connected to a threaded screw 13. When the threaded screw 13 rotates, it is convenient to drive the structure on the rod to move synchronously; guide rods 14 are arranged on both sides of the threaded screw 13, and the guide rods 14 can stabilize the structure on the rod when it is displaced, and improve the effective stability; and the guide rods 14 are welded inside the fixed frame 5, which can improve the effective stability; a movable plate 15 is connected to the threaded screw 13 and the guide rod 14, and the movable plate 15 can conveniently drive the structures on both sides to move synchronously when it is displaced; a No. 1 slide groove 16 is welded on both sides of the movable plate 15, and the No. 1 slide groove 16 can facilitate the subsequent vertical displacement of the internal structure; the internal vertical sliding connection of the two groups of No. 1 slide grooves 16 is connected with a cleaning brush 17, which is convenient for cleaning when the cleaning brush 17 is horizontally displaced, and convenient for subsequent disassembly when the cleaning brush 17 is vertically displaced.

[0031] The utility model is at work: when the gas is circulating, the gas contacts the protective net 19 through the No. 2 pipe 7. At this time, the impurities inside the gas can be isolated by the protective net 19, thereby improving the purity of the gas during circulation. When working for a long time, there are more impurities on the surface of one side of the protective net 19, which leads to a decrease in the efficiency of gas circulation. The drive motor 12 is started, and the drive motor 12 drives the threaded screw 13 on the output end of one side to rotate. When the threaded screw 13 rotates, it drives the movable plate 15 on the threaded screw 13 to stably move on the guide rod 14. At this time, the cleaning brush 17 inside the No. 1 slide groove 16 on both sides of the movable plate 15 is convenient for horizontal position When the cleaning brush 17 and the protective net 19 need to be disassembled and cleaned later, the "L"-shaped limit block 11 inside the fixed block 10 is held and rotated. When the "L"-shaped limit block 11 rotates, the sealing plate 8 below is no longer limited. At this time, the sealing plate 8 can be easily removed by holding the handle 9 above the sealing plate 8. At this time, the protective net 19 can be easily disassembled by sliding through the No. 2 slide groove 18, and the cleaning brush 17 can be easily disassembled by sliding through the No. 1 slide groove 16 for subsequent cleaning work.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
