[0002] A filter bag is a key component for filtration and dust removal. Usually, a cylindrical filter bag is vertically suspended in a dust collector. Its fabric and design pursue high-efficiency filtration, easy dust stripping and long durability. The main function of the filter bag is to separate dust from the flue gas to achieve dry and high-efficiency dust removal. The material of the filter bag can be natural fiber or synthetic fiber. Common materials include cotton, hemp, wool, cocoon silk, asbestos fiber, glass fiber and some synthetic fibers, etc. During the use of the filter bag, it is necessary to install the filter bag in the installation hole on the surface of the flower plate to ensure the normal operation of the filter bag; in the prior art, the installation of the filter bag mostly adopts an elastic clamping method. A spring piece is provided at the upper end of the filter bag. During installation, it is necessary for personnel to apply a force to the spring piece to deform the spring piece, and then move the spring piece into the installation hole of the flower plate. By using the elastic reset of the spring piece, the filter bag is in close contact with the installation hole of the flower plate to achieve the installation of the filter bag. However, in order to ensure the sealing effect between the filter bag and the flower plate, the elastic force of the spring piece is relatively large, and a large force needs to be applied by personnel during the installation process. Moreover, in order to ensure the accuracy of the installation position, it is also necessary to frequently adjust the installation position of the filter bag, resulting in inconvenient disassembly and assembly of the filter bag.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , this embodiment provides a technical solution: a filter cloth bag installation structure that is convenient for disassembly and assembly, including a flower plate 1 and a fixing mechanism 3;

[0021] Flower plate 1: An external thread ring 2 is provided on its upper surface, facilitating the connection between the flower plate 1 and the fixing mechanism 3;

[0022] Fixing mechanism 3: It includes an internal thread ring 31, a conical ring 32, a filter bag connection ring 33 and a sealing gasket 34. The internal thread ring 31 is threadedly connected to the outer arc surface of the external thread ring 2. The upper end of the internal thread ring 31 is provided with a conical ring 32. The inner arc surface diameter of the conical ring 32 gradually decreases from top to bottom. The lower end of the conical ring 32 is provided with a filter bag connection ring 33. The sealing gasket 34 is installed on the inner arc surface of the mounting hole of the flower plate 1. The sealing gasket 34 can move up and down. The sealing gasket 34 is installed in cooperation with the conical ring 32. By rotating the internal thread ring 31, through the threaded connection between the internal thread ring 31 and the external thread ring 2, the conical ring 32 is driven to move downward. The conical ring 32 is used to squeeze the sealing gasket 34 to cause it to deform, and the sealing between the flower plate 1 and the filter bag is carried out through the sealing gasket 34, and the connection between the flower plate 1 and the filter bag is quickly completed. The fixing mechanism 3 further includes a limiting thread ring 35. The limiting thread ring 35 is threadedly connected to the inner arc surface of the mounting hole of the flower plate 1. The upper end of the limiting thread ring 35 is fixedly connected to the lower surface of the sealing gasket 34. According to the working environment of the filter bag, by rotating the limiting thread ring 35, through the threaded connection between the limiting thread ring 35 and the flower plate 1, the limiting thread ring 35 moves upward, so that the deformation amplitude generated by the conical ring 32 squeezing the sealing gasket 34 is greater and the sealing effect is stronger. The fixing mechanism 3 further includes a chute 36, a sliding column 37 and a limiting insertion column 38. The chute 36 is arranged on the inner arc surface of the internal thread ring 31. The limiting insertion column 38 is slidably connected inside the chute 36. The limiting insertion column 38 is installed in cooperation with the limiting insertion hole on the surface of the external thread ring 2. A sliding column 37 is arranged in the middle of the limiting insertion column 38. The sliding column 37 is slidably connected to the guiding groove on the inner wall of the chute 36. The fixing mechanism 3 further includes a spring 39. The spring 39 is arranged between the limiting insertion column 38 and the inner wall of the chute 36. The spring 39 is movably sleeved on the outer arc surface of the sliding column 37. When the conical ring 32 moves downward to a certain position, the limiting insertion column 38 and the limiting insertion hole on the surface of the external thread ring 2 are horizontally coincident. Under the elastic force of the spring 39, the limiting insertion column 38 slides in the chute 36 until it is inserted into the limiting insertion hole. At the same time, a sound is emitted after the limiting insertion column 38 is inserted, reminding the personnel that the filter bag has been installed in place. The relative rotation of the internal thread ring 31 and the external thread ring 2 is restricted by the limiting insertion column 38, making the installation of the filter bag firm. The end of the sliding column 37 passes through the inside of the internal thread ring 31 and is provided with a pull ring 4, which is convenient for pulling the sliding column 37 to move. Reinforcing ribs 5 are respectively arranged on the inner arc surface of the limiting thread ring 35 to improve the strength of the limiting thread ring 35 and at the same time facilitate the rotation of the limiting thread ring 35. Anti-slip plates 6 are respectively arranged on the outer arc surface of the internal thread ring 31 to increase the friction force of the outer arc surface of the internal thread ring 31 and facilitate the rotation of the internal thread ring 31.

[0023] The working principle of an easy-to-disassemble and assemble filter bag installation structure provided by the utility model is as follows: When installing the filter bag, the filter bag is fixedly connected with the filter bag connecting ring 33. Rotate the internal thread ring 31. Through the threaded connection between the internal thread ring 31 and the external thread ring 2, drive the conical ring 32 to move downward. Use the conical ring 32 to squeeze the sealing gasket 34 to cause deformation, and seal between the flower plate 1 and the filter bag through the sealing gasket 34. When the conical ring 32 moves down to a certain position, the limit insertion post 38 and the limit insertion hole on the surface of the external thread ring 2 are horizontally coincident. Under the elastic force of the spring 39, the limit insertion post 38 slides in the chute 36 until it is inserted into the limit insertion hole. At the same time, a sound is emitted after the limit insertion post 38 is inserted, reminding the personnel that the filter bag has been installed in place. Use the limit insertion post 38 to restrict the relative rotation between the internal thread ring 31 and the external thread ring 2, so that the installation of the filter bag is firm. When it is necessary to disassemble the filter bag, use the pull ring 4 to pull the sliding column 37 to move, overcome the elastic force of the spring 39, make the limit insertion post 38 leave the limit insertion hole, cancel the restriction on the internal thread ring 31, and then rotate the internal thread ring 31 in the reverse direction to disassemble the filter bag. The disassembly and assembly process is simple and labor-saving.

[0024] The above are only the embodiments of the utility model, and do not limit the patent scope of the utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the utility model.
