Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filter cartridge technology, and specifically provides a dust collector cage and filter unit that can be sealed and connected. Background Technology
[0002] In industrial dust collection systems, the dust collector cage, as the core supporting component of the filter bag, directly affects the operational stability of the filtration system. However, existing dust collector cages and filter units have significant technical defects in engineering applications, leading to reduced system filtration efficiency and high maintenance costs, specifically as follows:
[0003] 1. Insufficient sealing performance at connection points; traditional threaded or snap-fit connection structures are prone to forming micro gaps. Under high wind pressure conditions, fine dust particles can penetrate into the clean area through these gaps, leading to a decrease in filtration efficiency. In severe cases, this can cause equipment corrosion failure and pose a potential risk to the occupational health of workers. In addition, the periodic vibration load during the filtration process may exacerbate the loosening of the connection points.
[0004] 2. The installation and disassembly process is complex and time-consuming; the traditional connection method involves cumbersome steps, requires the use of special tools, and in some cases requires multiple people to work together, which significantly extends the equipment maintenance cycle.
[0005] Therefore, it is necessary to design a dust collector cage and filter unit that can be sealed and connected. Utility Model Content
[0006] To solve the above problems, this utility model provides a sealable dust collector cage and filter unit.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sealable dust collector cage, comprising a first connecting section and a second connecting section. Both the first and second connecting sections include a frame, a fixing seat, and a fixing member. The fixing seat and the fixing member are respectively fixedly installed at both ends of the frame. A rotating member is fixedly installed at the outer end of the fixing member of the first connecting section, and a connecting member is fixedly installed at the outer end of the fixing member of the second connecting section. A flanged connecting plate is uniformly integrally formed on the inner ring of the outer end of the rotating member. A guide plate is fixedly installed on the inner ring of the outer end of the connecting member. An opening groove corresponding to the flanged connecting plate is uniformly opened on the inner end of the connecting member. The first connecting section and the second connecting section are connected by the cooperation of the rotating member and the connecting member. A sealing gasket is provided between the rotating member and the connecting member.
[0008] Furthermore, the skeleton includes connecting ribs and rings, with a plurality of rings uniformly welded onto the connecting ribs.
[0009] Furthermore, a limiting cylinder is fixedly installed on the inner ring of the fastener, and a limiting protrusion is uniformly and integrally formed on the outer wall of the limiting cylinder. The ring at the end of the connecting rib is engaged with the limiting protrusion.
[0010] Furthermore, there are three flanged connecting plates, and the ends of the flanged connecting plates are bent outwards.
[0011] Furthermore, the guide plate includes an inclined guide section, a positioning section, and a limiting section. The inclined guide section and the limiting section are located on both sides of the positioning section, and the opening slot is located at the outer end of the inclined guide section. The height of the inclined guide section gradually increases from the outside to the inside. The height of the positioning section is equal to the height of the outer end of the inclined guide section, and the height of the limiting section is greater than the height of the inner end of the inclined guide section.
[0012] Furthermore, the thickness of the sealing gasket is greater than the height difference between the inner side of the bend of the flanged connecting plate and the positioning section.
[0013] A sealable dust collection and filtration unit includes a sealable dust collection cage as described above, and also includes a filter bag. The filter bag is sleeved on the outside of the cage, and both ends of the filter bag are fixedly installed in a fixing seat and a fixing member, respectively.
[0014] Furthermore, the inner side of the fixing base, the space between the fixing member and the limiting cylinder are all filled with polyurethane sealant, and both ends of the filter bag are fixed to the fixing base and the fixing member by polyurethane sealant.
[0015] The beneficial effects of using this utility model are:
[0016] This utility model is designed with rotating and connecting parts. Through the connection process of insertion, rotation and locking, the docking and fixing of two connecting sections can be completed quickly and accurately, and self-locking and anti-loosening can be achieved. It is simple to operate, requires no tools or multiple people to cooperate, greatly reduces installation time and improves connection stability.
[0017] This invention features a sealing gasket between the rotating component and the connecting component. During the connection process between the rotating component and the connecting component, the gasket is always under compression. Through elastic deformation, it completely fills the microscopic gaps on the contact surface, achieving a stable and effective seal.
[0018] This utility model features a limiting protrusion on the fixing component, which facilitates the connection between the fixing component and the frame, forming a mechanical lock. This effectively prevents relative displacement between the frame and the fixing component, ensuring the overall stability of the cage and thus guaranteeing the stability of the dust removal and filtration unit.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0027] Example 1
[0028] Reference Figures 1 to 4 A sealable dust collector cage includes a first connecting section and a second connecting section. Both the first and second connecting sections include a frame 1, a fixing seat 2, and a fixing member 3. The fixing seat 2 and the fixing member 3 are respectively fixedly installed at both ends of the frame 1. A rotating member 4 is fixedly installed on the outer end of the fixing member 3 of the first connecting section, and a connecting member 5 is fixedly installed on the outer end of the fixing member 3 of the second connecting section. A flanged connecting plate 41 is uniformly integrally formed on the inner ring of the outer end of the rotating member 4. A guide plate 51 is fixedly installed on the inner ring of the outer end of the connecting member 5. An opening groove 52 corresponding to the flanged connecting plate 41 is uniformly opened on the inner end of the connecting member 5. The first connecting section and the second connecting section are connected by the cooperation of the rotating member 4 and the connecting member 5. A sealing gasket 6 is provided between the rotating member 4 and the connecting member 5.
[0029] The frame 1 serves as a support and allows gas to pass through smoothly.
[0030] Rotating component 4 and connecting component 5 are installed on fixed component 3 by welding.
[0031] The design of the rotating part 4 and the connecting part 5 involves placing the flanged connecting plate 41 on the guide plate 51 after passing through the opening groove 52. After rotation, the rotating part 4 and the connecting part 5 are connected. At the same time, a sealing gasket 6 is set between the rotating part 4 and the connecting part 5. When the rotating part 4 and the connecting part 5 are connected, the sealing gasket 6 will be squeezed to complete the sealing at the connection between the first connecting section and the second connecting section.
[0032] The sealing gasket 6 is made of rubber, which generates a large frictional force on the rotating part 4 and the connecting part 5 when it is squeezed, thus helping to connect and fix the rotating part 4 and the connecting part 5.
[0033] Specifically, the skeleton 1 includes connecting ribs 11 and rings 12, with multiple rings 12 evenly welded onto the connecting ribs 11.
[0034] The connecting rib 11 is a longitudinal support rod, and the ring 12 is welded on it to form a grid frame, which can ensure its strength and support effect, ensure that the cage will not deform under high wind pressure, and at the same time, the grid structure allows gas to pass freely and disperses dust load.
[0035] Specifically, the inner ring of the fastener 3 is fixedly installed with a limiting cylinder 31, and the outer wall of the limiting cylinder 31 is uniformly and integrally formed with a limiting protrusion 32. The ring 12 at the end of the connecting rib 11 is engaged with the limiting protrusion 32.
[0036] The connection between the fastener 3 and the frame 1 is achieved through the ring 12 and the limiting protrusion 32. The ring 12 at the end of the frame 1 is fixed by the limiting protrusion 32, and a firm connection is achieved through a simple structure.
[0037] The connection between the frame 1 and the fixing seat 2 can be achieved by welding, or a protruding structure can be set on the fixing seat 2 to fix the frame 1.
[0038] Specifically, there are three flanged connecting plates 41, and the ends of the flanged connecting plates 41 are bent outward.
[0039] The flanged connecting plate 41 is set in three, which can effectively determine the plane position, ensure that the cross-section of the rotating part 4 can be set parallel to the end face of the connecting part 5, ensure that the force is uniform during connection, and at the same time achieve a uniform sealing effect between the rotating part 4 and the connecting part 5.
[0040] The end of the flanged connecting plate 41 is bent outward to avoid obstructing the central space and thus avoid affecting the flow of gas.
[0041] Specifically, the guide plate 51 includes an inclined guide section 511, a positioning section 512, and a limiting section 513. The inclined guide section 511 and the limiting section 513 are located on both sides of the positioning section 512, and the opening slot 52 is located at the outer end of the inclined guide section 511. The height of the inclined guide section 511 gradually increases from the outside to the inside. The height of the positioning section 512 is equal to the height of the outer end of the inclined guide section 511, and the height of the limiting section 513 is greater than the height of the inner end of the inclined guide section 511.
[0042] Connector 5 is a passive component, which works with rotating component 4 to complete the connection.
[0043] When the rotating part 4 is connected to the connecting part 5, the bent part of the flanged connecting plate 41 passes through the opening groove 52. Then, while squeezing the sealing gasket 6, the rotating part 4 is deflected, so that the bent part of the flanged connecting plate 41 fits onto the inclined guide section 511 of the guide plate 51. Then, the rotating part 4 continues to rotate, so that the flanged connecting plate 41 passes through the inclined guide section 511 and reaches the positioning section 512. Under the restriction of the inner end of the inclined guide section 511 and the limiting section 513, the rotating part 4 is positioned. At this time, the sealing gasket 6 is in a squeezed state, providing a seal, thus completing the connection and fixation between the rotating part 4 and the connecting part 5.
[0044] Specifically, the thickness of the sealing gasket 6 is greater than the height difference between the inner side of the bend of the flanged connecting plate 41 and the height of the positioning section 512.
[0045] The inner side of the bend of the flanged connecting plate 41 mentioned above refers to the position where the flanged connecting plate 41 contacts the guide plate 51. Limiting the thickness of the sealing gasket 6 and the dimensions of the flanged connecting plate 41 and the guide plate 51 ensures that the sealing gasket 6 remains in a compressed state after the rotating part 4 and the connecting part 5 are connected and fixed, achieving good sealing performance. At the same time, it can increase the friction with the rotating part 4 and the connecting part 5, reducing the risk of vibration and loosening.
[0046] Example 2
[0047] like Figure 5 As shown, a sealable dust removal filter unit includes a sealable dust removal cage as in Embodiment 1, and also includes a filter bag 7. The filter bag 7 is sleeved on the outside of the frame 1, and the two ends of the filter bag 7 are respectively fixedly installed in the fixing seat 2 and the fixing member 3.
[0048] Filter bag 7 is installed to capture dust and perform filtration.
[0049] Specifically, the inner side of the fixing base 2, the space between the fixing member 3 and the limiting cylinder 31 are filled with polyurethane sealant, and the two ends of the filter bag 7 are fixed to the fixing base 2 and the fixing member 3 by polyurethane sealant.
[0050] Polyurethane sealant is used to fill the gaps, forming a chemical bond and secondary seal, ensuring that the filter bag 7 does not shift under high wind pressure or temperature changes, improving filtration accuracy and durability, while also having a buffering effect to absorb vibration and impact.
[0051] Example 3
[0052] A sealable dust collector cage also includes an intermediate connecting section. The main body of the intermediate connecting section consists of a frame 1 and a fixing member 3. Two fixing members 3 are respectively installed at both ends of the frame 1. Rotating members 4 and connecting members 5 are respectively installed on the two fixing members 3, which are used to connect with the first connecting section and the second connecting section respectively.
[0053] Multiple intermediate connecting sections can be spliced and extended by connecting the rotating part 4 and the connecting part 5, so that the length of the dust collector cage and the dust collector filter unit can be adjusted according to actual needs.
[0054] Example 4
[0055] For the frame 1, the connecting ribs 11 can be bent to make the frame 1 bend as a whole, so that it can be assembled into a bendable dust removal filter unit, thus expanding its application range.
[0056] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of this utility model. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this utility model.
