Description

Technical Field

[0001] This invention relates to the technical field of gas environmental purification, and in particular to a dust removal device with a filter bag that is easy to disassemble and replace. Background Technology

[0002] Fine particulate matter (PM10 and PM2.5) not only seriously endangers human health but also has a profound impact on the ecological environment and climate change. Against this backdrop, air pollution control, as an important component of ecological civilization construction, has become a key focus of national environmental protection policies, driving the rapid development and technological upgrading of the environmental protection industry.

[0003] However, existing fabric filters typically use flanges or pressure plates to fix the filter bags to the tube sheet. After long-term operation, the filter bags are prone to failure due to dust clogging, high-temperature aging, or chemical corrosion, requiring periodic replacement. However, disassembly not only easily damages the tube sheet sealing surface and is complicated, but also often causes secondary dust re-entrainment due to directly tearing the filter bags, resulting in environmental pollution and harming the health of operators. Summary of the Invention

[0004] To overcome the drawback of baghouse dust collectors where filter bags are difficult to disassemble and replace, this invention provides a dust collection device that allows for easy disassembly and replacement of filter bags.

[0005] A dust removal device for easy disassembly and replacement of filter bags includes a base, a housing fixedly mounted on the base, a fixing plate fixedly mounted inside the housing, and a mounting plate connected to the fixing plate by mounting bolts. Both the fixing plate and the mounting plate have several corresponding through holes. A connecting ring is fixedly mounted at each through hole of the mounting plate. The connecting ring has an annular fastening groove. A detachable and replaceable filter bag assembly is installed on the connecting ring through the fastening groove.

[0006] As an improvement to the above solution, the filter bag assembly includes an installation ring, an elastic buckle, a connecting frame, and a dust collection bag. The installation ring is engaged with the connecting ring by the interlocking of the elastic buckle and the fastening groove. The connecting frame and the dust collection bag are both installed on the installation ring, and the connecting frame is located inside the dust collection bag to fix and support the dust collection bag.

[0007] As an improvement to the above solution, it also includes circumferentially distributed connecting rods, which are fixed to the outer wall of the mounting ring. The inner wall of the connecting ring is provided with multiple protruding guide blocks along the circumferential direction. Each guide block corresponds to a connecting rod. The inner wall of the connecting ring has circumferentially distributed guide grooves, and the guide blocks are used to guide the connecting rods to the corresponding guide grooves.

[0008] As an improvement to the above solution, the lower part of the connecting ring is connected to a threaded ring via an internal thread, and a guide frame is provided on the threaded ring. The bottom of the guide frame is provided with a guide expansion surface that gradually narrows upward.

[0009] As an improvement to the above solution, it also includes locking blocks symmetrically distributed along the connecting ring, the locking blocks being slidably connected to the connecting ring, and the mounting ring being fixed with a retaining ring for limiting the locking blocks.

[0010] As an improvement to the above solution, the retaining ring has circumferentially distributed retaining teeth, and the interval between adjacent retaining teeth is set as a retaining groove. The retaining block moves and engages with any of the retaining grooves of the retaining ring.

[0011] As an improvement to the above solution, the end of the card block near the card ring is set as a V-shaped surface, and the outer ends of each tooth of the card ring are also set as V-shaped surfaces. The purpose of this is to allow the card block to move smoothly and engage in the slot of the card ring.

[0012] As an improvement to the above solution, the guide frame is slidably connected to the threaded ring, and a guide ring surface is provided on the side of the guide frame near the clamping block, and the guide ring surface is pressed and engaged with the clamping block.

[0013] The beneficial effects of this invention are as follows:

[0014] This invention, through the design of elastic buckles and connecting rings, allows dust bags to be quickly and easily installed onto dust collection devices without the need for tools. It also simplifies the disassembly process, especially when a thorough cleaning is required. All dust bags can be removed at once by simply removing a few key components, reducing the time and complexity required by traditional fixing methods.

[0015] During the disassembly process, the invention, due to its optimized design, can more effectively control the secondary raising of dust, reduce secondary pollution to the environment, and protect the health of workers.

[0016] This invention forms an anti-slip mechanism through a connecting rod and guide block structure. By simply rotating the entire filter bag assembly, the connecting rod is fully screwed into the guide groove, which further reinforces the bag and avoids the risk of slipping down due to the increased weight caused by dust accumulation. This effectively prevents the dust bag from accidentally falling off during operation and improves the reliability and continuous operation capability of the dust removal system.

[0017] The guiding expansion surface of this invention not only assists in installation, but also plays a role in concentrating and guiding air during ventilation, ensuring that the gas is filtered upward along the optimal path, thereby improving filtration efficiency.

[0018] This invention utilizes wind force to guide the expansion surface, causing the guide frame to move upward and fixing the mounting ring with a locking block. This double reinforcement design enhances the stability of the overall structure, prevents loosening caused by vibration, and ensures that the dust collection bag remains stable even under high wind speed conditions, without being affected by vibration, thus guaranteeing the continuous and efficient operation of the dust collection system.

Detailed Implementation

[0028] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0029] Example 1: A dust removal device with easy disassembly and replacement of filter bags, please refer to the attached document. Figure 1 To be continued Figure 5The device includes a base 101 for supporting the entire dust removal unit. A housing 102 is fixedly connected to the upper part of the base 101. The top and bottom of the housing 102 are respectively provided with an outlet and an inlet. Dust-laden gas enters from the inlet and exits from the outlet, and is filtered and removed inside the housing 102. A fixing plate 103 is fixedly connected to the side of the housing 102 near the outlet. The fixing plate 103 is connected to a mounting plate 1031 by mounting bolts. Both the fixing plate 103 and the mounting plate 1031 have six corresponding through holes 1302. A connecting ring 104 is fixedly connected to each of the through holes 1302 of the mounting plate 1031. The connecting ring 104 has an annular fastening groove 1041. A detachable and replaceable filter bag assembly is installed on the connecting ring 104 through the fastening groove 1041.

[0030] The filter bag assembly includes an mounting ring 105, elastic buckles 106, a connecting frame 107, and a dust collection bag 108. The mounting ring 105 is engaged with the connecting ring 104 by the mutual engagement of the multiple elastic buckles 106 with the fastening groove 1041. The connecting frame 107 and the dust collection bag 108 are both mounted on the mounting ring 105. The connecting frame 107 is located inside the dust collection bag 108 and is used to fix and support the dust collection bag 108 to prevent the dust collection bag 108 from tightening, which would reduce its dust removal effect.

[0031] Please see the appendix Figure 5 and attached Figure 6 It also includes circumferentially distributed connecting rods 201, which are fixed to the outer wall of the mounting ring 105. The inner wall of the connecting ring 104 is provided with a plurality of protruding guide blocks 202 along the circumferential direction. Each guide block 202 corresponds to one of the connecting rods 201. The inner wall of the connecting ring 104 has circumferentially distributed guide grooves 203. The guide blocks 202 are used to guide the connecting rods 201 into the corresponding guide grooves 203. The guide grooves 203 are used to limit the connecting rods 201, so that the connecting rods 201 cannot move up and down at will, thereby preventing the mounting ring 105 from moving up and down at will.

[0032] The quick installation operation of the filter bag assembly is as follows: First, insert the mounting ring 105 upward into the connecting ring 104, so that the elastic buckles 106 on the mounting ring 105 are all engaged in the fastening grooves 1041 of the connecting ring 104. In this way, the entire filter bag assembly can be quickly installed on the connecting ring 104.

[0033] Furthermore, during the upward insertion process, the guide block 202 guides the connecting rod 201. When the connecting rod 201 is guided to the guide groove 203, the entire filter bag assembly is rotated so that the connecting rod 201 is fully screwed into the guide groove 203. In this way, the entire filter bag assembly is further reinforced, preventing the dust bag 108 from gradually increasing in weight due to the accumulation of dust during the filtration process. This would cause the elastic buckle 106 to automatically slide down from the fastening groove 1041, and consequently, the entire filter bag assembly to slide down.

[0034] The operation for quick disassembly and replacement of filter bag assembly is as follows: First, rotate the entire filter bag assembly in the opposite direction so that the connecting rod 201 rotates out of the guide groove 203 in the opposite direction. Then, pull the entire filter bag assembly downwards so that the elastic buckle 106 breaks out of the fastening groove 1041. Then, each filter bag assembly together with the filter material on the dust removal bag 108 can be taken down and cleaned.

[0035] When it is necessary to remove all filter bag assemblies on the mounting plate 1031 at the same time, the above-mentioned operation of disassembling and replacing them one by one is omitted. Simply remove the mounting bolts between the fixing plate 103 and the mounting plate 1031, and then remove the mounting plate 1031 and all the filter bag assemblies on it as a whole for quick disassembly, cleaning and replacement.

[0036] In summary, by designing the elastic buckle 106 and the connecting ring 104, the present invention enables the dust bag 108 to be quickly and easily installed on the dust removal device without the use of tools. At the same time, it simplifies the disassembly process. Especially when a complete cleaning is required, all the dust bags 108 can be removed at once by removing only a few key components, reducing the time and complexity required by traditional fixing methods.

[0037] During the disassembly process, the invention, due to its optimized design, can more effectively control the secondary raising of dust, reduce secondary pollution to the environment, and protect the health of workers.

[0038] The present invention forms an anti-slip mechanism through the structure of the connecting rod 201 and the guide block 202. By simply rotating the entire filter bag assembly, the connecting rod 201 is fully screwed into the guide groove 203, which further strengthens the filter bag and avoids the risk of downward slippage due to the increased weight caused by dust accumulation. This effectively prevents the dust bag 108 from accidentally falling off during operation and improves the reliability and continuous operation capability of the dust removal system.

[0039] Example 2: Based on Example 1, specifically, please refer to the appendix. Figure 7 and attached Figure 8The lower part of the connecting ring 104 is connected to a threaded ring 301 via an internal thread 302. A guide frame 304 is slidably connected to the threaded ring 301 in the vertical direction. The bottom of the guide frame 304 is provided with a guide expansion surface 303 that gradually narrows upward. A guide ring surface 305 is provided on the upper side of the guide frame 304. A locking block 306 is slidably connected to the connecting ring 104 in the horizontal direction and is symmetrically distributed on the left and right sides of the connecting ring 104. A retaining ring 307 is fixedly connected to the mounting ring 105. The guide ring surface 305 and the locking block 306 are press-fitted. The retaining ring 307 has circumferentially distributed locking teeth. The interval between adjacent locking teeth is set as a locking groove. When the guide frame 304 moves upward, it presses the locking block 306 through the guide ring surface 305 to move horizontally and lock into any locking groove of the retaining ring 307.

[0040] The end of the locking block 306 near the locking ring 307 is set with a V-shaped surface, and the outer ends of each tooth of the locking ring 307 are also set with a V-shaped surface. The purpose of this is to enable the locking block 306 to move more smoothly into the slot of the locking ring 307, thereby optimizing the locking path.

[0041] During the upward insertion process, the guiding expansion surface 303 assists in guiding the mounting ring 105 into the connecting ring 104; and during the ventilation and dust removal process, the guiding expansion surface 303 has the effect of concentrating and guiding the air, allowing the gas to be filtered upward along the dust bag 108 and then pass upward through the through hole 1302; in addition, the converged wind force acts on the guiding expansion surface 303, causing the guide frame 304 to move upward, and the guide frame 304 presses the locking block 306 into the locking ring 307 through the guide ring surface 305 to fix the mounting ring 105, preventing the mounting ring 105 from rotating randomly due to wind vibration, which would cause the connecting rod 201 to rotate out of the guide groove 203 in the opposite direction, achieving a double reinforcement effect.

[0042] In summary, the guiding expansion surface 303 of the present invention not only assists in installation, but also plays a role in concentrating and guiding air during ventilation, ensuring that the gas is filtered upward along the optimal path, thereby improving filtration efficiency.

[0043] The present invention utilizes wind force acting on the guiding expansion surface 303 to cause the guide frame 304 to move upward and fix the mounting ring 105 through the locking block 306. This double reinforcement design enhances the stability of the overall structure, prevents loosening caused by vibration, and ensures that the dust bag 108 can remain stable even under high wind speed conditions, and will not be affected by vibration to work normally, thereby ensuring the continuous and efficient operation of the dust removal system.

These descriptions are merely for explaining the principles of the embodiments of the present invention and should not be construed as limiting the scope of protection of the embodiments of the present invention in any way.
