[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1 and Figure 2 and Figure 3 As shown, it includes a sealed box 1 and a detection component 2. A cavity 3 is arranged in the box 1. The filtering device cooperates with other equipment. An inlet 11 and an outlet 12 are also arranged on the box 1. The inlet 11 and the outlet 12 are both communicated with the cavity 3. The inlet 11 and the outlet 12 are respectively connected to two devices. The gas mixed with dust particles enters the cavity 3 from the inlet 11 and then goes out from the outlet 12.

[0031] The housing 1 is also provided with a rotating assembly 4, which includes a screw rod 41 and a positioning block 42. The screw rod 41 extends into the cavity 3, the screw rod 41 is rotatably arranged, and the positioning block 42 is rotatably arranged with the screw rod 41. By rotating the screw rod 41, the positioning block 42 can be moved.

[0032] The detection component 2 includes a hollow tube 21 and a tester 22. The hollow tube 21 is set on the positioning block 42. The hollow tube 21 can move with the positioning block 42. An air inlet hole 23 is set on the hollow tube 21. The air inlet hole 23 is aligned with the second filter 14. The tester 22 is connected with the hollow tube 21 in an adsorption manner. Dust particles remain on the inner surface of the second filter 14. The tester 22 inhales air, and the air inlet hole 23 is aligned with the inner surface of the second filter 14. In this way, the dust particles remaining on the inner surface of the second filter 14 are adsorbed into the tester 22. The tester 22 can detect the size of the dust particles. The tester 22 is set on the box 1.

[0033] If the tester 22 detects that the dust particle size is not within the set value range, the tester 22 will also issue an alarm when displaying the value, requiring manual verification.

[0034] Rotate the screw rod 41, and the positioning block 42 moves on the screw rod 41. The width of the hollow tube 21 is the same as the width of the second filter screen 14, and the length direction of the screw rod 41 is consistent with the length direction of the second filter screen 14. In this way, when the positioning block 42 moves back and forth on the screw rod 41, the hollow tube 21 moves back and forth, and the air inlet hole 23 adsorbs the inner surface of the second filter screen 14 back and forth, so that the inner surface of the second filter screen 14 is within the detection range of the tester 22.

[0035] The detection component 2 also includes a branch pipe 24, which is arranged on the positioning block 42. A vertical pipe 25 is also arranged on the branch pipe 24. The two ends of the vertical pipe 25 are respectively connected to the branch pipe 24 and the hollow tube 21. The dust particles on the inner surface of the second filter 14 enter the hollow tube 21 from the air inlet 23, and then enter the branch pipe 24 through the vertical pipe 25. The branch pipe 24 is connected to the tester 22.

[0036] The vertical pipe 25 can also support the hollow pipe 21 , and the number of vertical pipes 25 is not limited.

[0037] Furthermore, the detection component 2 also includes an adapter 26, a return air pipe 27 and an outlet pipe 28. The adapter 26 is connected to the branch pipe 24. The two ends of the return air pipe 27 are respectively connected to the adapter 26 and the tester 22. The adapter 26 can lift the return air pipe 27 to prevent the return air pipe 27 from falling on the screw 41. The tester 22 absorbs dust particles through the return air pipe 27 and the adapter 26 and detects the size of the dust particles. The outlet pipe 28 is set at the outlet end of the tester 22. After detection by the tester 22, the dust particles are discharged from the outlet pipe 28.

[0038] The rotating assembly 4 also includes a first guide rod 43, a second guide rod 44 and a motor 45. The first guide rod 43 and the second guide rod 44 are arranged in parallel on both sides of the screw rod 41. The positioning block 42 is slidably arranged on the first guide rod 43 and the second guide rod 44. The screw rod 41 is connected to the driving end of the motor 45. The motor 45 drives the screw rod 41 to rotate forward and reverse, so that the positioning block 42 can move back and forth, and the air inlet 23 can absorb dust particles back and forth.

[0039] The box body 1 is also provided with a device slot 5, which is arranged adjacent to the cavity 3. The motor 45 and the tester 22 are both arranged in the device slot 5, so as to prevent the motor 45 and the tester 22 from protruding outside.

[0040] A pressure gauge 6 is also provided in the equipment slot 5. The pressure gauge 6 is connected to the interior of the cavity 3 through a pipeline. The gas in the cavity 3 enters the pressure gauge 6 through the pipeline. The pressure gauge 6 tests the pressure in the cavity 3, and then the gas flows out from another pipeline. A cover plate 7 is also provided at the open end of the equipment slot 5. A display is provided on the cover plate 7. The test values ​​of the pressure gauge 6 and the tester 22 are displayed on the display.

[0041] like Figure 4 As shown, a first filter 13 is provided at the inlet 11, and a second filter 14 is provided at the outlet 12. The mixed gas is first filtered by the first filter 13, then enters the cavity 3, and then filtered by the second filter 14. The first filter 13 and the second filter 14 filter dust particles of different sizes respectively, that is, the mesh size of the first filter 13 and the mesh size of the second filter 14 are different.

[0042] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
