[0033] The opposite ends of the threaded rod 8 are provided with fixing members 9, one end of the fixing member 9 is fixedly connected with the inner surface of the surrounding pipe 3, and the threaded rod 8 is rotationally connected with the fixing member 9 through the rotating rod 10;

[0034] The diameter of the rotating connection part of the fixing member 9 and the threaded rod 8 is smaller than the diameter of the threaded rod 8, so that the dust collecting box 6 and the fine screen 4 are prevented from contacting the threaded rod 8 and being scratched when moving, and the contact part of the fixing member 9 and the threaded rod 8 is tightly fitted, so that the threaded rod 8 will not be offset and affect the operation.

[0035] The corresponding two inner surfaces of the surrounding pipe 3 are fixedly provided with support plates one 13 and two 18, and the inner vertical surfaces of the support plates one 13 and two 18 are provided with inclined grooves 11;

[0036] The support plates one 13 and two 18 are inclined, so that the fine screen 4 is in an inclined state when it is inside the surrounding pipe 3, and the larger particle impurities falling from above roll down to the lower side of the fine screen 4 due to the inclination of the fine screen 4 and their own gravity, and then will not fall into the lower fan 5 to cause damage thereto.

[0037] The inclined grooves 11 are arranged at the same inclination angle as the fine screen 4, and the fixing members 9 are fixedly arranged on the side surfaces of the inclined grooves 11;

[0038] The two inclined grooves 11 form a limiting space, the fine screen 4 is inserted into the limiting space, and the contact part of the fine screen 4 and the support plates one 13 and two 18 is tightly fitted, so as to prevent the impurities falling from above from falling into the gap between the fine screen 4 and the support plates one 13 and two 18 and causing damage to the threaded rod 8.

[0039] The outer surface of the surrounding pipe 3 is provided with hole one 12 and hole two 17, and the part of hole two 17 in contact with the fine screen 4 is tightly attached.

[0040] The outer surface of hole one 12 is adjacent to the outer surface of hole two 17, and hole one 12 is close to the lower end of hole two 17, so that the fine screen 4 is inserted into the surrounding pipe 3 from hole two 17, and the impurities on the upper surface of the fine screen 4 roll to the lower side, without causing congestion, and are discharged from hole one 12.

[0041] The inclination angle of hole two 17 is consistent with the fine screen 4, and the angle between the lower surface of hole one 12 and the upper surface of the fine screen 4 is greater than or equal to 180° and less than 270°.

[0042] The height of hole one 12 is greater than the mesh diameter of the coarse screen 2, so that the larger impurities falling through the coarse screen 2 can be smoothly discharged from hole one 12, preventing internal congestion and affecting production and operation, and the contact part between the lower surface of hole one 12 and the upper surface of the fine screen 4 will not have a low-lying part, preventing impurities from accumulating and being difficult to clean.

[0043] The bottom of the surrounding pipe 3 is provided with an air outlet 16.

[0044] The bottom of the dust collection box 6 completely covers the air outlet 16, so that the bottom of the surrounding pipe 3 supports the dust collection box 6, and the dust collection box 6 will not fall during use.

[0045] The working principle of the above embodiment is as follows:

[0046] In use, the fan 5 is electrically connected to the external power supply line, the clamping assembly 15 fixes the valve body, the polishing assembly 14 polishes the valve body, and the impurities generated during the polishing process of the valve body fall through the coarse screen 2. When the larger particles contact the fine screen 4, they will be blocked and roll down to the lower side of the fine screen 4 due to the inclination of the fine screen 4 and its own gravity, and are discharged from hole one 12. Smaller particles are attracted by the fan 5 and pass through the fine screen 4 to continue to fall, and when passing through the dust collection box 6, they will be attached to the filter. The filtered air is discharged from the air outlet 16, completing the filtration. When a force is applied to the dust collection box 6 and the fine screen 4 outwardly or inwardly, the half-thread grooves 7 on both sides of the dust collection box 6 and the fine screen 4 will drive the threaded rod 8 to rotate, thereby enabling the dust collection box 6 and the fine screen 4 to move smoothly inside and outside the surrounding pipe 3, and the disassembly and installation can be completed without the need for external tools.

[0047] The mounting mode, the connecting mode or the setting mode disclosed in the embodiment are all common mechanical connecting modes, and can be implemented as long as the beneficial effects can be achieved. In addition, the electrical components appearing in the embodiment are electrically connected with the master controller and the power supply. The master controller can be a conventional known device such as a computer which plays a control role. A person skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technology also belongs to the common knowledge in the field. Therefore, the specific structure, composition and working principle of the embodiment will not be described in detail.
