Description

Technical Field

[0001] This utility model relates to the field of industrial dust collector technology, specifically an easily disassembled industrial dust collector. Background Technology

[0002] Baghouse dust collectors are core components in the industrial dust removal field, primarily used for industrial dust control. The filter bags are the core filtration elements of a baghouse dust collector, and their installation reliability directly affects dust removal efficiency and equipment operational stability. In existing technologies, filter bags are typically fixed using perforated plates, with mainstream installation methods including spring-loaded ring type, clamp / clamp type, and bolt connection type.

[0003] Existing spring-loaded installations achieve sealing and fixation through the friction and elasticity between the elastic ring at the bag opening and the perforated plate. While offering advantages such as tool-free installation and quick disassembly, this method relies on the installer's strength and alignment accuracy. Furthermore, the elastic ring may experience a decrease in sealing performance due to dust accumulation or aging over long-term use. Clamp / clamp installations secure the bag opening to the perforated plate flange with metal clamps, providing strong sealing but requiring tools and resulting in lower disassembly efficiency. Bolted connections achieve rigid fixation through flanges and bolts, suitable for harsh conditions such as high temperature and high pressure, but the disassembly process is cumbersome, requiring individual bolt tightening, which is time-consuming and labor-intensive. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an industrial dust collector that is easy to disassemble and assemble.

[0005] To achieve the objective of this utility model, the technical solution adopted is as follows: A disassembly-and-assemble industrial dust collector is designed, comprising:

[0006] The dust collector has a tube sheet inside its inner cavity. The tube sheet has multiple mounting holes, and each mounting hole contains a filter cartridge support. A dust collector bag is fitted over the outside of the filter cartridge support.

[0007] A disassembly and assembly mechanism, disposed between the filter cartridge support and the tube sheet, is used to achieve a detachable connection between the filter cartridge support and the tube sheet. The disassembly and assembly mechanism includes:

[0008] A retaining ring is fixedly connected to the top of the filter cartridge support, and the retaining ring is magnetic;

[0009] An arc-shaped permanent magnet is embedded in the flower plate outside the mounting hole and corresponds to the position of the fixing ring;

[0010] A positioning component is disposed between the tube sheet and the fixing ring for positioning the installed filter cartridge support.

[0011] Preferably, the positioning component includes positioning rods on both sides of the fixing ring near the end of the tube sheet and positioning holes on both sides of the mounting hole tube sheet, wherein the positioning rods and positioning holes are positioned correspondingly and are sized to fit each other.

[0012] Preferably, the outer sides of the fixing ring are provided with arc-shaped handles, and the ends of the two arc-shaped handles near the fixing ring are fixedly connected to a rotating shaft, and the other end of the rotating shaft is rotatably connected to the outside of the fixing ring through a bearing.

[0013] Preferably, a clamp is fitted on the outside of the dust collector bag, which is used to fix the dust collector bag to the outside of the filter cartridge support.

[0014] Preferably, the arc-shaped permanent magnet is integrally formed using neodymium iron boron permanent magnet material through powder metallurgy.

[0015] Preferably, the bottom of the dust collector is connected to a dust discharge pipe with a valve, one end of the dust collector is connected to a dust inlet pipe, the top of the dust collector is provided with a detachable tank cover, and one end of the tank cover is connected to an exhaust pipe.

[0016] Preferably, a rubber sealing gasket is fixedly connected to one end of the fixing ring near the filter cartridge support, and the rubber sealing gasket is elastic.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model achieves quick connection between the filter cartridge support and the tube sheet without tools through the magnetic attraction between the fixing ring and the arc-shaped permanent magnet. This avoids the cumbersome process of traditional clamp / clamp or bolt connection installations that require tools. At the same time, the magnetic connection method requires less force and alignment accuracy from the installer, reducing the difficulty of operation. In addition, compared with spring expansion ring installation, the magnetic structure is not easily affected by dust accumulation or aging, and can maintain stable connection performance even after long-term use, improving equipment maintenance efficiency and reliability.

[0019] 2. This utility model, through the cooperation of the positioning rod and the positioning hole, plays a pre-positioning role in the installation of the filter cartridge support, ensuring that the fixing ring and the arc-shaped permanent magnet are accurately aligned, thereby improving the efficiency and stability of the magnetic connection. At the same time, the positioning component can limit the lateral displacement of the filter cartridge support, enhance its installation stability on the tube sheet, and avoid positional deviation caused by airflow impact or vibration.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: An easily detachable industrial dust collector, see [link to example]. Figures 1 to 5 The system includes: a dust collector tank 1, the inner cavity of which is provided with a tube sheet 2, the tube sheet 2 having multiple mounting holes 21, each mounting hole 21 having a filter cartridge support 31, and a dust collector bag 32 fitted on the outside of the filter cartridge support 31; a disassembly and assembly mechanism, disposed between the filter cartridge support 31 and the tube sheet 2, for detachable connection of the filter cartridge support 31 and the tube sheet 2, the disassembly and assembly mechanism including: a fixing ring 3, fixedly connected to the top of the filter cartridge support 31, and the fixing ring 3 being magnetic; an arc-shaped permanent magnet 35, embedded in the tube sheet 2 outside the mounting holes 21, and corresponding to the position of the fixing ring 3; and a positioning component, disposed between the tube sheet 2 and the fixing ring 3, for positioning the installed filter cartridge support 31.

[0028] During operation, the filter cartridge support 31 and the tube sheet 2 can be quickly connected without tools through the magnetic attraction between the fixing ring 3 and the arc-shaped permanent magnet 35. This avoids the cumbersome process of using tools in traditional clamp / clamp or bolt connection installations. At the same time, the magnetic connection method requires less force and alignment accuracy from the installer, reducing the difficulty of operation. In addition, compared with spring expansion ring installation, the magnetic structure is not easily affected by dust accumulation or aging, and can maintain stable connection performance even after long-term use, improving equipment maintenance efficiency and reliability.

[0029] For details, see Figure 4 and Figure 5The positioning component includes positioning rods 5 on both sides of the fixed ring 3 near the tube sheet 2 and positioning holes 51 on both sides of the tube sheet 2 of the mounting hole 21. The positioning rods 5 and the positioning holes 51 are corresponding in position and adapted in size. Through the cooperation of the positioning rods 5 and the positioning holes 51, the positioning component plays a pre-positioning role during the installation of the filter cartridge support 31, ensuring that the fixed ring 3 and the arc-shaped permanent magnet 35 are accurately aligned, improving the efficiency and stability of the magnetic connection. At the same time, the positioning component can limit the lateral displacement of the filter cartridge support 31, enhance its installation stability on the tube sheet 2, and avoid positional deviation caused by airflow impact or vibration.

[0030] Further, see Figure 3 Both sides of the fixed ring 3 are provided with arc-shaped handles 41. The ends of the two arc-shaped handles 41 near the fixed ring 3 are fixedly connected to a rotating shaft 4. The other end of the rotating shaft 4 is rotatably connected to the outside of the fixed ring 3 through a bearing. When installing or disassembling the filter cartridge support 31, the handles can be turned out to provide a force application point, making it easier for the operator to hold and apply force, reducing the difficulty of operation. When not in use, the handles can be turned to a position close to the fixed ring 3 to reduce space occupation and avoid interference with surrounding components. This improves the ease of disassembly and assembly while taking into account the compactness and practicality of the structure, making it especially suitable for the internal environment of industrial dust collectors with limited space.

[0031] It is worth noting that, see Figure 3 The dust collector bag 32 is fitted with a clamp 33 on its outer side. The clamp 33 is used to fix the dust collector bag 32 to the outer side of the filter cartridge support 31. Fixing the dust collector bag 32 to the outer side of the filter cartridge support 31 by clamping the clamp 33 can provide a more reliable sealing and fixing effect, thereby improving the efficiency of dust collector bag 32 assembly and disassembly.

[0032] It is worth noting that, see Figure 5 The arc-shaped permanent magnet 35 is integrally formed using neodymium iron boron permanent magnet material through powder metallurgy. Leveraging the high remanence, high coercivity, and high energy product of neodymium iron boron permanent magnet material, the integrally formed arc-shaped permanent magnet 35 through powder metallurgy ensures a uniform and stable magnetic field distribution, providing durable and reliable magnetic attraction. This effectively resists the effects of dust pollution and high-temperature environments, extends service life, reduces the risk of filter cartridge loosening due to magnetic attenuation, and improves the safety and stability of equipment operation.

[0033] It is worth mentioning that, see Figure 1The bottom of the dust collector 1 is connected to a dust discharge pipe 12 with a valve, and one end of the dust collector 1 is connected to a dust inlet pipe 11. The top of the dust collector 1 is provided with a detachable tank cover 13, and one end of the tank cover 13 is connected to an exhaust pipe 14. The dust discharge pipe 12 and the valve facilitate the regular cleaning of dust in the dust collector, avoiding excessive dust accumulation that could affect the filtration efficiency. The detachable tank cover 13 provides convenience for the inspection and replacement of internal components without the need to disassemble the entire tank, significantly shortening maintenance time.

[0034] It is worth mentioning that, see Figure 4 A rubber sealing gasket 34 is fixedly connected to one end of the fixing ring 3 near the filter cartridge support 31. The rubber sealing gasket 34 is elastic. By setting the rubber sealing gasket 34, the gap between the fixing ring 3 and the tube sheet 2 can be filled, the sealing performance can be enhanced, and dust leakage can be prevented. Its elasticity can compensate for the small displacement caused by processing errors or vibration, ensuring the stability of the sealing effect. In addition, the elastic sealing gasket can also absorb some vibration energy, reduce damage to the filter cartridge support 31 and the tube sheet 2, extend the service life of the components, and improve the overall reliability of the equipment.

[0035] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0036] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
