Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically to an assembled dust collector filter bag. Background Technology

[0002] Dust collector filter bags are a type of high-efficiency dust collection filter material. They are made from raw materials such as polyester staple fiber, PPS fiber, PP polypropylene, and aramid fiber. They have good air permeability, high dust collection rate, and are easy to clean, with a dust removal efficiency of up to 98.99%.

[0003] Existing patent publication number CN213725380U discloses an easy-to-install assembled dust collector filter bag, belonging to the technical field of industrial dust removal equipment. This easy-to-install assembled dust collector filter bag includes a filter bag and filter bag clamping mechanisms for clamping and fixing the upper and lower ends of the filter bag. Two filter bag clamping mechanisms are arranged opposite to each other. Each filter bag clamping mechanism includes a main clamping ring, with an annular groove on its inner wall. An annular magnet is fixed to the bottom of the annular groove. Two arc-shaped clamping iron blocks are located on the inner wall of the main clamping ring outside the annular magnet, forming a circular structure. The arc-shaped clamping iron blocks match the annular groove. This solution utilizes the magnetic attraction effect of the annular magnet and the arc-shaped iron blocks to quickly clamp and position the filter bag, completing the assembly of the filter bag. Compared with other fixing methods in the prior art, it not only has a better fixing effect but also effectively avoids mechanical damage, and is easy to disassemble and use.

[0004] The above-mentioned solution has the following problems during implementation. In order to facilitate the cleaning of the filter bag, the device is designed with a disassembly structure that can separate the mounting ring from the filter bag. However, in order to make the mounting ring and the filter bag more secure, the disassembly structure is equipped with several sets of bolts for fixing. This requires tools to tighten the bolts one by one during installation and to unscrew them one by one during disassembly, which is time-consuming and troublesome. This makes it inconvenient to disassemble and assemble the mounting ring and the filter bag, greatly reducing the practicality of the device. Therefore, we provide an assembled dust collector filter bag to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an assembled dust collector filter bag, which solves the problem that in the prior art, the disassembly and assembly structure of the device uses several sets of bolts to fix the mounting ring and the filter bag to make the installation ring and the filter bag more secure. This requires tools to tighten the bolts one by one during installation and to unscrew them one by one during disassembly, which is time-consuming and troublesome. This makes it inconvenient to disassemble and assemble the mounting ring and the filter bag, and greatly reduces the practicality of the device.

[0006] This utility model provides the following technical solution: an assembled dust collector filter bag, including a filter cartridge and an mounting ring. A fixing ring is fixedly connected to the top of the filter cartridge, and a filter bag body is provided at the bottom of the mounting ring. Both the filter bag body and the mounting ring are sleeved on the surface of the filter cartridge. A magnetic attraction component is provided between the mounting ring and the fixing ring. A disassembly and assembly mechanism for installing the mounting ring and the filter bag body together is provided at the bottom of the mounting ring. The disassembly and assembly mechanism includes a fixing component for limiting and fixing the filter bag body and a locking component for locking the fixing component.

[0007] As a preferred embodiment of the above technical solution, the magnetic attraction assembly includes a magnet ring and an iron block ring. The magnet ring is installed at the bottom end of the fixing ring, and the iron block ring is installed at the top end of the mounting ring. The bottom end of the magnet ring and the top end of the iron block ring are attached to each other and adsorbed together.

[0008] As a preferred embodiment of the above technical solution, the fixing component includes a connecting ring, a first limiting sleeve, and a second limiting sleeve. The connecting ring is connected to the bottom end of the mounting ring, and the upper side of the filter bag body is sleeved on the surface of the connecting ring. The first limiting sleeve and the second limiting sleeve are rotatably mounted on the bottom end of the mounting ring and are sleeved on the outer side of the filter bag body. The lower and upper sides of the ends of the first limiting sleeve and the second limiting sleeve that are close to each other are respectively connected to a second connecting block and a first connecting block. The first connecting block and the second connecting block are engaged together by a locking component.

[0009] As a preferred embodiment of the above technical solution, the locking component includes a sliding groove and a limiting groove. The sliding groove is located at the bottom of the connecting block one, a spring is installed on the upper side of the sliding groove, and a limiting block is slidably installed at the lower opening of the sliding groove. The limiting groove is located at the top of the connecting block two, and the limiting block is inserted into the limiting groove.

[0010] As a preferred embodiment of the above technical solution, the inner wall of the slide groove is provided with a guide opening, and one end of the limiting block is connected to a pusher block through a connecting block, and the connecting block slides within the guide opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a disassembly and assembly mechanism. An upward-moving lever drives a limiting block until it is pulled out of the limiting groove and moves into the sliding groove, compressing the spring. At this point, the first and second limiting sleeves can be rotated to open them, allowing the filter bag to be removed from the connecting ring for easier cleaning. Alternatively, the upper side of the filter bag body can be placed on the connecting ring, and then the first and second limiting sleeves can be rotated to close them. Simultaneously, the second limiting sleeve drives the first connecting block, and when the first connecting block pushes the limiting block against the second connecting block, the limiting block... The spring will be pushed into the groove to compress the connecting block until the first connecting block and the second connecting block are fully engaged. The limiting block can then be pushed into the limiting groove by the spring's restorative force, thereby limiting and locking the first and second limiting sleeves. This fixes the filter bag body between the first and second limiting sleeves and the connecting ring, thus achieving installation. In this way, no tools are needed when disassembling and installing the mounting ring and the filter bag body. Moreover, the operation steps are simple, more convenient, and greatly increase the convenience of the device. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figure 1and Figure 2 As shown, this utility model provides a technical solution: an assembled dust collector filter bag, including a filter cartridge 1 and an mounting ring 2. A fixing ring 11 is fixedly connected to the top of the filter cartridge 1, and a filter bag body 21 is provided at the bottom of the mounting ring 2. Both the filter bag body 21 and the mounting ring 2 are fitted onto the surface of the filter cartridge 1. A magnetic suction assembly 3 is provided between the mounting ring 2 and the fixing ring 11. The magnetic suction assembly 3 includes a magnet ring 31 and an iron block ring 32. The magnet ring 31 is installed at the bottom of the fixing ring 11, and the iron block ring 32 is installed at the top of the mounting ring 2. The bottom of the magnet ring 31 and the top of the iron block ring 32 are attached and adsorbed together. By pulling the mounting ring 2 downward with force until the mounting ring 2 drives the iron block ring 32 to separate from the magnet ring 31, the mounting ring 2 and the filter bag body 21 can be removed from the filter cartridge 1. This makes it more convenient to clean or replace the filter cartridge 1 and the filter bag body 21.

[0023] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, the bottom end of the mounting ring 2 is provided with a disassembly and assembly mechanism for mounting the mounting ring 2 and the filter bag body 21 together. The disassembly and assembly mechanism includes a fixing component 4 for limiting and fixing the filter bag body 21 and a locking component 5 for locking the fixing component 4. The fixing component 4 includes a connecting ring 41, a first limiting sleeve 42 and a second limiting sleeve 43. The connecting ring 41 is connected to the bottom end of the mounting ring 2. The upper side of the filter bag body 21 is sleeved on the surface of the connecting ring 41. The first limiting sleeve 42 and the second limiting sleeve 43 are rotatably mounted on the bottom end of the mounting ring 2. The first limiting sleeve 42 and the second limiting sleeve 43 are sleeved on the outside of the filter bag body 21. The lower and upper sides of the ends of the first limiting sleeve 42 and the second limiting sleeve 43 that are close to each other are respectively connected to a second connecting block 45 and a first connecting block 44. The first connecting block 44 and the second connecting block 45 are engaged together by the locking component 5. This structure can be unlocked by releasing the locking component. By rotating component 5, the first limiting sleeve 42 and the second limiting sleeve 43 can be opened, allowing the filter bag to be removed from the connecting ring 41. This allows the filter bag to be rubbed during cleaning, making it easier and cleaner. Rotating the first limiting sleeve 42 and the second limiting sleeve 43 closes them, causing the connecting block 1 44 and the connecting block 2 45 to engage. Locking component 5 then locks the connecting block 1 44 and the connecting block 2 45 together, allowing the mounting ring 2 and the filter bag body 21 to be installed. The inner walls of the first limiting sleeve 42 and the second limiting sleeve 43 are equidistantly connected with protrusions 46, increasing the friction between the first limiting sleeve 42 and the second limiting sleeve 43 and the filter bag body 21, thus ensuring a more secure installation of the filter bag body 21.

[0024] As one implementation method in this embodiment, such as Figure 4and Figure 5 As shown, the locking assembly 5 includes a slide groove 51 and a limiting groove 54. The slide groove 51 is located at the bottom of the connecting block 44. A spring 52 is installed on the upper side of the slide groove 51, and a limiting block 53 is slidably installed at the lower opening of the slide groove 51. The two ends of the spring 52 are connected to the inner wall of the slide groove 51 and the top of the limiting block 53, respectively. The limiting groove 54 is located at the top of the connecting block 45, and the limiting block 53 is inserted into the limiting groove 54. A guide opening 55 is provided on the inner wall of the slide groove 51. One end of the limiting block 53 is connected to a lever 56 through the connecting block. The connecting block slides within the guide opening 55. By levering the lever 56, the limiting block 53 moves upward until it is pulled out of the limiting groove 54 and moves into the slide groove 51, compressing the spring 52, thus releasing the locking mechanism of the connecting block 44. The locking of connecting block 2 45 and connecting block 1 44, when closed, causes limiting block 53 to abut against connecting block 2 45. Limiting block 53 is then pushed into the slide groove 51 to compress spring 52 until connecting block 1 44 and connecting block 2 45 are fully engaged. When limiting block 53 corresponds to limiting groove 54, limiting block 53 can be pushed into limiting groove 54 by the spring force of spring 52. This can limit and lock the first limiting sleeve 42 and the second limiting sleeve 43, so that the filter bag body 21 is clamped and fixed between the first limiting sleeve 42 and the second limiting sleeve 43 and the connecting ring 41. In this way, no tools are needed when disassembling and installing the mounting ring 2 and the filter bag body 21. Moreover, the operation steps are simple, more convenient and time-saving, greatly increasing the convenience of the device.

[0025] As one implementation method in this embodiment, such as Figure 4 and Figure 5 As shown, an anti-accidental contact component 6 is provided on the lower side of the outer wall of the connecting block 44. The anti-accidental contact component 6 includes a fixing block 61, which is fixedly connected to the outer wall of the connecting block 44. A rotating rod 62 is rotatably installed on the top of the fixing block 61. This structure can limit the position of the toggle block 56 by rotating the top of the toggle block 56 with the rotating rod 62, thus better preventing the toggle block 56 from being accidentally touched and affecting the installation of the filter bag body 21, and greatly increasing the practicality of the device.

[0026] It should be noted that the fixed block 61 and the rotating rod 62 are located on one side of the dial block 56, and the fixed block 61 is spaced a little distance from the dial block 56. In this way, when the rotating rod 62 rotates away from the dial block 56, the fixed block 61 and the rotating rod 62 will not easily affect the longitudinal movement of the dial block 56.

[0027] Working principle: To remove the mounting ring 2 and filter bag body 21 from the filter cylinder 1, simply pull the mounting ring 2 downwards until it separates the iron block ring 32 from the magnet ring 31. This makes cleaning or replacing the filter cylinder 1 and filter bag body 21 easier. Alternatively, to separate the mounting ring 2 from the filter bag body 21, simply rotate the rotating rod 62 until it moves away from the lever 56. Then, rotate the lever 56 upwards. The lever 56 moves the limiting block 53 upwards until it is pulled out of the limiting groove 54 and moves into the slide groove 51 to compress the spring 52. Then, rotate the first limiting sleeve 42 and the second limiting sleeve 43 to open them, allowing the filter bag to be removed from the connecting ring 41. This allows the filter bag to be rubbed during cleaning, making it easier and cleaner.

[0028] When the filter bag is clean and ready for installation, simply slip the upper side of the filter bag body 21 onto the connecting ring 41, then rotate the first limiting sleeve 42 and the second limiting sleeve 43 to close them. At this time, the first limiting sleeve 42 and the second limiting sleeve 43 will also cause the connecting block 1 44 and the connecting block 2 45 to engage. Simultaneously, when the connecting block 1 44 causes the limiting block 53 to abut against the connecting block 2 45, the limiting block 53 will be pushed into the slide groove 51 to compress the spring 52 until the connecting block 1 44 and the connecting block 2 45 are fully engaged. When the limiting block 53 corresponds to the limiting groove 54, the limiting block 53 can be pushed into the limiting groove 54 by the spring force of the spring 52. Within 4, the first limiting sleeve 42 and the second limiting sleeve 43 can be limited and locked, so that the filter bag body 21 is clamped between the first limiting sleeve 42 and the second limiting sleeve 43 and the connecting ring 41 for fixation, thereby realizing installation. In this way, no tools are needed when disassembling and installing the installation ring 2 and the filter bag body 21, and the operation steps are simple, more convenient and time-saving, greatly increasing the convenience of the device. Finally, rotate the rotating rod 62, so that the rotating rod 62 rotates the top of the lever 56, which can limit the lever 56 and better prevent the lever 56 from being accidentally touched and affecting the installation of the filter bag body 21.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
