The plug 4 is provided with a gas supply pipeline 5 and a gas extraction pipeline 7 penetrating through itself in the vertical direction. The gas supply pipeline 5 passes through a feeding bin 6, and the feeding bin 6 stores colored particles 15. The particle size of the colored particles 15 is greater than the inner diameter of the filter hole on the filter cartridge 11 to be detected. The gas extraction pipeline 7 passes through a filtering bin 8, and the filtering bin 8 is used for filtering and recycling the colored particles 15 in the gas extraction pipeline 7.
[0021] Specifically, the plug 4 is in a cylindrical structure, and the outer diameter of the plug 4 is substantially equal to the inner diameter of the filter cartridge 11 to be detected. Preferably, the plug 4 is made of silica gel or rubber, and the outer diameter of the plug 4 is slightly larger than the inner diameter of the filter cartridge 11 to be detected. After the plug 4 is inserted into the upper end of the filter cartridge 11, the plug 4 is slightly elastically deformed, and the outer contour of the plug 4 tightly abuts against the inner contour of the filter cartridge 11 to achieve sealing, thereby avoiding the gas and colored particles 15 at the plug 4 from being sprayed out of the upper end of the filter cartridge 11.
[0022] Specifically, the plug is below the compression ring, and the gas supply pipeline and the gas extraction pipeline on the plug penetrate through the plug in the vertical direction to avoid affecting the abutment of the compression ring.
[0023] In the embodiment, the support piece includes a bottom plate 1 and a support frame 2. The bottom plate 1 is horizontally arranged, and the support frame 2 is fixed to the bottom plate 1 and vertically extends upward. The upper end of the support frame 2 is fixed with a transversely extending cross beam 3.

[0024] Specifically, the bottom plate 1 is a circular plate or a square plate, and the central axes of the support ring 12 and the compression ring 10 pass through the center of the bottom plate 1. The support frame 2 is a vertical rod structure. The lower end of the support frame 2 is fixedly connected with the bottom plate 1 through an angle iron and a bolt, and the upper end of the support frame 2 is fixedly connected with the cross beam 3 through an angle iron and a bolt. One end of the cross beam 3 is fixed with the support frame 2, and the other end extends transversely and is suspended.
[0025] In this embodiment, the first lifting assembly 9 is installed between the support ring 12 and the bottom plate 1, and the second lifting assembly 14 is installed between the pressing ring 10 and the cross beam 3.
[0026] In this embodiment, the first lifting assembly 9 and the second lifting assembly 14 are respectively electric push rods or hydraulic cylinders.
[0027] In this embodiment, the first lifting assembly 9 is detachably fixed with the support ring 12, and the second lifting assembly 14 is detachably fixed with the pressing ring 10.
[0028] Specifically, taking the electric push rod as an example for the first lifting assembly 9 and the second lifting assembly 14. The extending rod of the first lifting assembly 9 extends upward and is fixed with the support ring 12 through bolts or buckle structures. The casing of the first lifting assembly 9 extends downward and is fixed with the bottom plate 1 through angle irons and bolts.
[0029] Similarly, the extending rod of the second lifting assembly 14 extends downward and is fixed with the lower pressing ring through bolts or buckle structures, and the casing of the second lifting assembly 14 extends upward and is fixed with the cross beam 3 through angle irons and bolts.
[0030] In this embodiment, the supply bin 6 has an inlet and an outlet, and the inlet and the outlet are located at the upper part of the supply bin 6 and are oppositely arranged.
[0031] Specifically, the supply bin 6 is a square bin, which has a square inner bin, and the projections of the inlet and the outlet along the extension direction of the gas supply pipeline coincide. A one-way valve is arranged on the gas supply pipeline, which is arranged to allow the gas supply pipeline to supply gas only to the plug 4 and the filter cartridge 11. When the gas passes through the supply bin 6, part of the colored particles 15 will enter the gas supply pipeline under the action of gas pressure and then be sprayed from the spray head.
[0032] In this embodiment, the filter bin 8 has a filter screen inside, which divides the filter bin 8 into a first bin body and a second bin body, wherein the first bin body is communicated with the plug 4, and the second bin body is communicated with the air extraction device.

[0035] Specifically, taking the support ring 12 as an example, it comprises a rigid ring and a flexible ring. The rigid ring is made of metal or plastic material, and the flexible ring is made of rubber or silica gel material. The rigid ring is used to connect the positioning rib, and the positioning rib is fixed with the upper end of the first lifting assembly. More specifically, the rigid ring and the flexible ring are coaxially arranged, and the end faces of the two are fixed by means of gluing or screw connection.

[0037] Working principle: when using the device, first make the compression ring 10 rise, the support ring 12 descend, and the distance between the compression ring 10 and the support ring 12 is adjusted to the maximum. Then the lower end of the filter cartridge 11 passes through the support ring 12 and is stopped by the positioning rib 13 to achieve support. Then control the first lifting assembly 9 and the second lifting assembly 14 to rise and fall, so that the compression ring 10 is pressed tightly at the upper end surface of the filter cartridge 11.
[0038] Insert the plug 4 into the upper end of the filter cartridge 11, and then the gas supply pipeline 5 delivers the gas with colored particles 15 into the filter cartridge 11. The user observes whether the outer contour of the filter cartridge 11 is contaminated or spouts colored particles 15.
[0039] If the colored particles 15 appear on the outer periphery of the filter cartridge 11, the remaining colored particles 15 in the filter cartridge 11 are recovered by using the air extraction pipeline 7, and then the filter cartridge 11 is recycled and repaired. If the colored particles 15 do not appear on the outer periphery of the filter cartridge 11, the remaining colored particles 15 in the filter cartridge 11 are recovered by using the air extraction pipeline 7, and then the filter cartridge 11 is placed back to the original position and accumulated for use.
