[0002] Filter bags are the core component of baghouse dust collectors, mainly used to capture dust and purify gas. They are widely used in industrial dust removal, air purification and other fields. Filter bags are bag-shaped filter elements made of fiber materials. They separate dust particles from dust-laden gas through interception, inertial collision and diffusion, thereby achieving gas purification.

[0003] To this end, the patent specification with publication number CN204563731U discloses a filter bag, including a filter bag body, an elastic ring inside the bag opening of the filter bag body, and a silicone resin layer on the outside of the filter bag body; the filter bag body is made of woven yarn; and two elastic rings are provided inside the bag opening of the filter bag body; the filter bag of this utility model, because the filter bag body has a silicone resin layer on the outside, improves the surface wear resistance, is not easily damaged under the impact of dust and particles, and improves the service life of the filter bag; at the same time, it reduces the moisture absorption capacity of the filter bag and increases the filtration effect of the filter bag.

[0004] The above-mentioned technology improves the surface wear resistance by adding a silicone resin layer to the filter bag body during use. However, in the process of use, traditional single-layer filter bags are prone to poor filtration effect. Therefore, a combined filter bag is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a combined filter bag to solve the problem that existing traditional single-layer filter bags are prone to poor filtration effect during the filtration process.

[0007] The bottom end of the mounting head is provided with a first filter bag, the first filter bag has an internal assembly structure, and the connection between the mounting head and the first filter bag is provided with a sealing structure.

[0008] The combined structure includes a second filter bag, which is installed inside the first filter bag. The top of the first filter bag has an installation groove, and a limiting groove is provided at the top of one side of the installation groove. An installation block is fixed to the outside of the second filter bag, and a limiting block is fixed to the top of the installation block.

[0009] Preferably, the mounting blocks are provided in multiple sets, and the multiple sets of mounting blocks are connected to the mounting groove in a rotary manner.

[0010] Preferably, the limiting block is inserted into the interior of the limiting groove, and the limiting block and the limiting groove form a limiting structure.

[0011] Preferably, a second flange is installed on the outer side of the bottom end of the mounting head, a first flange is installed on the outer side of the top end of the first filter bag, a fixing bolt is fixed to the top end of the first flange, and a nut is installed on the outer side of the fixing bolt.

[0012] Preferably, a second sealing groove is provided inside the top of the first filter bag, a first sealing groove is provided at the top of the second filter bag, a first sealing ring is installed inside the second sealing groove, and a second sealing ring is installed inside the first sealing groove.

[0013] Preferably, the outer side of the fixing bolt is provided with external threads, and the inner side of the nut is provided with internal threads, forming a threaded connection between the fixing bolt and the nut.

[0014] Preferably, the bottom end of the mounting head presses the first sealing ring into the interior of the first sealing groove, and a sealed connection is formed between the mounting head and the first filter bag.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] With its modular structure, the use of a second filter bag allows for dual filtration in conjunction with the first filter bag, resulting in better filtration performance. Furthermore, the mounting block and mounting groove enable quick installation of the mounting block, making the installation and removal of the second filter bag more convenient.

[0017] By incorporating a sealing structure and utilizing the cooperation of the first and second sealing rings, a multi-stage seal can be achieved at the connection between the mounting head and the first filter bag. This ensures that the connection between the mounting head and the first filter bag will not leak during operation, thus completing the sealing process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model embodiment provides a combined filter bag, such as Figures 1-6 As shown, a combined filter bag includes an installation head 1 and a first filter bag 2;

[0027] The bottom end of the mounting head 1 is provided with a first filter bag 2, the inside of the first filter bag 2 is provided with a combination structure 4, and the connection between the mounting head 1 and the first filter bag 2 is provided with a sealing structure 3.

[0028] The combined structure 4 includes a second filter bag 401, which is installed inside the first filter bag 2. The top of the first filter bag 2 has an installation groove 403. A limiting groove 405 is provided at the top of one side of the installation groove 403. An installation block 402 is fixed to the outside of the second filter bag 401. A limiting block 404 is fixed to the top of the installation block 402. Multiple sets of installation blocks 402 are provided. Multiple sets of installation blocks 402 are connected to the installation groove 403 by a screw. The limiting block 404 is inserted into the limiting groove 405. The limiting block 404 and the limiting groove 405 form a limiting structure.

[0029] In a further preferred embodiment of this utility model, such as Figures 3-6As shown: When using the first filter bag 2, the second filter bag 401 is installed inside the first filter bag 2. During installation, the mounting block 402 is aligned with the mounting groove 403 and then inserted into the mounting groove 403. After insertion, the second filter bag 401 is rotated to one side, causing the mounting block 402 to rotate into one side of the mounting groove 403. When the mounting block 402 rotates to one side of the mounting groove 403, the limiting block 404 will be inserted into the limiting groove 405. Since the limiting block 404 is made of rubber and has a certain elasticity, it can be installed into the limiting groove 405, thus completing the installation of the mounting block 402. This makes it easier to install or remove the second filter bag 401. Through the combined use of the second filter bag 401 and the first filter bag 2, a double filtration can be performed, resulting in better filtration performance.
