With the use of the sealing mechanism 5, the hollow tube 2 and the filter cartridge 3 are disconnected for a short time. Subsequently, through the use of the adjusting mechanism 6, the fixing effect of the filter cartridge 3 at the center position of the positioning mechanism 4 can be released, and the filter cartridge 3 can be pushed. Subsequently, through the use of the rotating mechanism 7, the positioning mechanism 4 can drive the filter cartridge 3 to rotate one hundred and twenty degrees inside the housing 1, that is, at one side of the push plate 62. This structure can quickly replace the filter cartridge 3 without affecting the continuous filtering of dust.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, the positioning mechanism 4 includes a circular plate 41, a circular plate bottom 42 is arranged below the circular plate 41, the circular plate 41 and the circular plate bottom 42 are fixedly connected by a long shaft rod 43, the circular plate 41 and the circular plate bottom 42 are both provided with a guide groove 44, the filter cartridge 3 is inserted into the guide groove 44, a circular hole 45 is provided on the circular plate 41, a groove 46 is provided on one side of the guide groove 44, a telescopic rod 47 is fixedly installed in the groove 46, and one end of the telescopic rod 47 is provided with a circular hole 45, and a groove 46 is provided on one side of the guide groove 44. A clamping block 48 is fixedly connected and inserted into a clamping slot 49. The clamping slot 49 is opened on the outside of the filter cartridge 3. A spring 50 is arranged on the outside of the telescopic rod 47. As both ends of the filter cartridge 3 are in the guide groove 44, the spring 50 squeezes one end of the clamping block 48 so that the clamping block 48 can be inserted into the clamping slot 49, thereby limiting the position of the filter cartridge 3 without affecting the movement and replacement of the filter cartridge 3 in the guide groove 44.

[0029] like Figure 2 and Figure 4As shown, the sealing mechanism 5 includes a cylinder 51, and the cylinder 51 is fixedly installed on the top of the box body 1.

The other end of the rotating rod 74 is inserted into an annular groove 75, and the annular groove 75 is opened in the box body 1. As the servo motor 71 drives the worm 72 to rotate, the worm 72 can drive the worm wheel 73 to mesh and rotate, so that one end of the rotating rod 74 is in the annular groove 75 to drive the positioning mechanism 4 to rotate.

[0032] like Figure 3 As shown, a fixing rod 9 is fixedly installed on the outer side of the filter cartridge 3, and a handrail 10 is fixedly connected to the other end of the fixing rod 9. This structure facilitates personnel to take the filter cartridge 3 at a certain position.

[0033] The utility model provides a dust filter box, and the specific working principle is as follows:

[0034] When the structure is in use, the cylinder 1 51 drives the annular plate 52 to move, that is, the annular plate 52 is away from one side of the circular plate 41 and sleeved on the outer side of the hollow tube 2, and the cylinder 3 63 drives the top plate 64 to move, so that the top plate 64 is separated from the inside of the circular groove 66, so as to be accommodated in the inside of the circular hole 65, and then the cylinder 2 61 drives the push plate 62 to move, so that the push plate 62 pushes the filter cartridge 3 to move in the direction of the box door groove 8, that is, the two ends of the filter cartridge 3 are in the guide groove 44 to slide, during which the block 48 is separated from the inside of the card groove 49. The filter cartridge 3 is then removed from the housing 1 by the outer side of the fixing rod 9 and the worm 72 is driven by the servo motor 71 to rotate, so that the worm 72 drives the worm wheel 73 to engage and rotate, so that one end of the rotating rod 74 rotates in the annular groove 75, so that the positioning mechanism 4 can drive the filter cartridge 3 to rotate one hundred and twenty degrees, and then the sealing mechanism 5 and the adjusting mechanism 6 repeat the work to complete the replacement effect of the filter cartridge 3.
