[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] See also Figure 1-5As shown, a filter cartridge of a dust collector that is easy to replace includes a box body 1, a replacement disk 2 is provided in the box body 1, a rotating groove 21 extending from the outer surface of the box body 1 is provided on the inner wall of the box body 1, one side of the replacement disk 2 extends from the outer surface of the box body 1 through the rotating groove 21, and rotates in the rotating groove 21, two filter tubes 3 are provided on the side surface of the replacement disk 2 located in the box body 1, and filter elements are provided in the two filter tubes 3 for filtering exhaust gas, two mounting holes 31 are provided on the replacement disk 2, both of which extend out of the outside of the replacement disk 2, one end of the filter tube 3 extends out of the replacement disk 2 through the mounting hole 31, and slides in the mounting hole 31, two built-in cavities 32 are provided in the replacement disk 2, the built-in cavity 32 is located between the mounting hole 31 and the rotating groove 21, a fixed slide rod 33 is provided in the built-in cavity 32, one end of the fixed slide rod 33 slides through the mounting hole 31, and the other end slides through When the filter tube 3 is in the state of being pressed down, the filter tube 3 is fixed with the filter element 34, and the filter element 34, when the filter element 3 is in the state of being pressed down, is pressed down, and the filter tube 3 is fixed with the filter element 34.

[0023] When the filter tube 3 on the top of the replacement disk 2 needs to be replaced, the replacement disk 2 is controlled to rotate, and the fixed slide bar 33 slides on the inner wall of the rotating groove 21. When the top filter tube 3 rotates to the bottom of the replacement disk 2, the fixed slide bar 33 slides into the groove 37. At this time, the tension spring 36 loses its restriction, thereby pulling the fixed slide bar 33 to move out of the fixed groove 34, so that the filter tube 3 is no longer fixed. In this way, after the filter tube 3 is replaced, the filter tube that needs to be replaced can be directly taken down, and there is no need to manually release the filter tube 3, which reduces the operating steps of the staff and improves the efficiency of replacing the filter tube 3. At the same time, this structure does not need to fix the filter tube 3. When the filter tube 3 rotates from bottom to top, the filter tube 3 can be automatically fixed.

[0024] More preferably, the end of the fixed slide bar 33 that contacts the inner wall of the rotating groove 21 is hemispherical, which increases the smoothness of the surface of the fixed slide bar 23, reduces the friction generated when the fixed slide bar 23 slides on the inner wall of the rotating groove 21, and avoids the problem of jamming caused by excessive friction between the fixed slide bar 23 and the inner wall of the rotating groove 21, thereby ensuring the stability and smoothness of the structure during operation.

[0025] A control cavity 22 connected to the rotating groove 21 is opened in the side wall of the box body 1, and an outer gear ring 23 is fixedly sleeved on the outer surface of the replacement disk 2 close to the control cavity 22. A motor 24 is fixedly installed on the inner wall of the box body 1. The output shaft of the motor 24 rotates and penetrates into the control cavity 22. A gear 25 is fixedly connected to one end of the output shaft of the motor 24 located in the control cavity 22. The gear 25 is meshed with the outer gear ring 23, so the replacement disk 2 can be driven to rotate by the motor 24.

[0026] An air supply pipe 4 is provided on the outer surface of the side of the box 1 away from the replacement disk 2, and one end of the air supply pipe 4 passes through the box 1. A Z-shaped connecting pipe 5 is slidably sleeved on the outer surface of the end of the air supply pipe 4 located in the box 1. The upper horizontal pipe of the Z-shaped connecting pipe 5 is slidably sleeved on the outer surface of the filter tube 3. An electric push rod 6 is fixedly connected to the inner wall of the side of the box 1 facing the replacement disk 2, and one end of the telescopic rod of the electric push rod 6 is fixedly connected to the outer surface of the Z-shaped connecting pipe 5. Therefore, the Z-shaped connecting pipe 5 can be driven to move by the electric push rod 6, thereby facilitating separation from the filter tube 5.

[0027] More preferably, a sealing rubber ring is provided on the inner wall of the Z-shaped connecting tube 5 , thereby increasing the sealing performance between the Z-shaped connecting tube 5 and the filter tube 3 and the air supply tube 4 .

[0028] Working principle: when the top filter tube 3 needs to be replaced, the electric push rod 6 is started, pulling the Z-shaped connecting tube 5 to separate from the filter tube 3. At this time, the motor 24 is started, and the output shaft of the motor 24 drives the gear 25 to rotate, so the gear 25 meshes and drives the replacement disk 2 to rotate, thereby rotating the old filter tube 3 from top to bottom, and the newly replaced filter tube 3 rotates from bottom to top. At the same time, the fixed slide bar 33 slides on the inner wall of the rotating groove 21. When the old filter tube 3 rotates to the bottom of the replacement disk 2, the fixed slide bar 33 slides into the groove 37. At this time, the tension spring 36 loses its restriction, thereby pulling the fixed slide bar 33 to move out of the fixed groove 34, so that the filter tube 3 is no longer fixed, and the old filter tube 3 can be directly taken down.
