[0002] In the existing bag dust removal technology, as the core filtering element, the performance of the dust removal filter bag directly determines the overall efficiency and operation stability of the dust collector.

[0003] At present, during the replacement process of traditional dust removal filter bags, due to a large amount of dust adhering to the surface of the filter bag, when the filter bag is taken out, the dust on the surface of the filter bag will also be taken out together and the dust will fly, which not only pollutes the working environment, but also affects the physical health of workers. In addition, when the filter bag is taken out for replacement, its surface will come into contact with the dust collector, and it is easy to be knocked and scratched, greatly reducing the dust removal effect and affecting the use, bringing many troubles to people. Therefore, based on the above shortcomings, a new type of dust removal filter bag is now introduced to improve this situation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of dust removal filter bag to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A new type of dust removal filter bag, including a first connection seat, a retaining ring is arranged on the outer wall of the first connection seat, a filter bag is installed at the bottom end of the first connection seat, a second connection seat is arranged at the bottom end of the outer wall of the filter bag, one end of a dust-proof cover is fixedly connected to the bottom end of the inner cavity of the second connection seat, the other end of the dust-proof cover extends out of the second connection seat and is installed with a connecting plate, a rubber pad is arranged on the inner wall of the connecting plate, one end of a connecting rope is installed on the top circumference of the connecting plate, and the other end of the connecting rope penetrates through the first connection seat and is installed with a handle.

[0006] Preferably, permanent magnetic blocks that attract each other are arranged on the outer walls of the second connection seat, the connecting plate and the first connection seat.

[0007] Preferably, the dust-proof cover and the filter bag are set to have the same length.

[0008] Preferably, the distance between the inner wall of the rubber pad and the filter bag is 1 cm.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1-2 , the present utility model provides a technical solution: A new type of dust removal filter bag, including a first connecting seat 1. An expansion ring 2 is arranged on the outer wall of the first connecting seat 1. The expansion ring 2 can clamp the whole on the dust collector. This is a known public technology and will not be elaborated here. The bottom end of the first connecting seat 1 is installed with a filter bag 3. The bottom end of the outer wall of the filter bag 3 is provided with a second connecting seat 4. The bottom end of the inner cavity of the second connecting seat 4 is fixedly connected to one end of a dust-proof cover 5. The other end of the dust-proof cover 5 extends out of the second connecting seat 4 and is installed with a connecting plate 6. A rubber pad 7 is arranged on the inner wall of the connecting plate 6. One end of a connecting rope 8 is installed on the top circumference of the connecting plate 6 on average. The other end of the connecting rope 8 penetrates through the first connecting seat 1 and is installed with a handle 9.

[0016] As a preferred solution, further, permanent magnet blocks 10 that attract each other are provided on the outer walls of the second connecting seat 4, the connecting plate 6, and the first connecting seat 1. The position of the connecting plate 6 can be adsorbed and fixed by the permanent magnet blocks 10.

[0017] As a preferred solution, further, the dust cover 5 and the filter bag 3 are set to have the same length, so as to ensure that the dust removal cover 5 can completely cover the filter bag 3.

[0018] As a preferred solution, further, the distance between the inner wall of the rubber pad 7 and the filter bag 3 is 1 cm.

[0019] As a preferred solution, further, anti-slip ridges are provided on the outer wall of the handle 9, and the handle 9 can be easily lifted by the anti-slip ridges.

[0020] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0021] When replacing and removing the filter bag 3, first pull the four handles 9 upward with force. The handles 9 will pull up the connecting plate 6 through the connecting ropes 8. At this time, the dust cover 5 will be gradually pulled out and cover the outside of the filter bag 3. When the dust cover 5 completely covers the filter bag 3, the staff can disconnect the expansion ring 2 from the dust collector and pull the first connecting seat 1 upward with force to perform the operation of replacing and removing the filter bag 3. During the process of removing the filter bag 3, due to the shielding of the dust cover 5, the dust attached to the filter bag 3 can be prevented from flying, and at the same time, the filter bag 3 can be prevented from being knocked and scratched by the dust cover 5. This device can not only suppress dust and effectively avoid the occurrence of dust flying when replacing the filter bag 3, but also protect the filter bag 3 from being scratched. The dust removal effect is significantly improved, ensuring the normal operation of the equipment. The operation is simple and convenient, the use is flexible, and the practicability is strong, which is suitable for popularization.
