Description

Technical Field

[0001] This utility model belongs to the technical field of bag dust collectors, and in particular relates to replaceable bag dust collector cages. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device that uses filter bags to filter gas, trapping dust on the outer surface of the filter bags. The filter bags are then cleaned by a reverse-flowing airflow from a blower pipe installed directly above. The bag cage is a crucial component of the baghouse dust collector; it is installed inside the filter bags to support them, prevent collapse, and ensure the baghouse dust collector can operate normally.

[0003] In the existing technology, the cages of bag filters are mostly integral structures. When the cages are partially corroded, deformed or damaged, the entire cage needs to be replaced, which not only increases maintenance costs, but also makes the replacement process cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] Replaceable bag filter cages include: unit cages and corresponding fixing components. Multiple unit cages are included, each consisting of a front support ring, a rear support ring, and multiple support rods. The fixing components include two sets of plug-in blocks, with two plug-in blocks in each set. Both sets of plug-in blocks are fixedly connected to the end of the front support ring. The surface of the rear support ring has plug-in slots corresponding to the plug-in blocks. Lateral movement of the unit cage allows the plug-in blocks on the front support ring to be laterally inserted into the plug-in slots of the rear support ring of another unit cage, thus completing the cage connection.

[0006] The cage frame is formed by combining multiple unit cages. When a unit cage is damaged, only the corresponding unit cage needs to be replaced, without the need to replace the whole cage, which greatly reduces maintenance costs.

[0007] As a preferred embodiment of the above technical solution, the fixing component further includes two limiting blocks. The front support ring has a first slot on both sides, and the rear support ring has a second slot on both sides. The limiting blocks are respectively inserted into the first slot of the front support ring and the second slot of the rear support ring of the other unit cage.

[0008] The limiting blocks are inserted longitudinally into the first and second slots of adjacent unit cages to restrict the lateral movement between the unit cages. Together with the plug-in blocks, the two unit cages are connected and fixed, which further strengthens the connection between adjacent unit cages and makes the cage frame more stable during use.

[0009] As a preferred embodiment of the above technical solution, the cross-section of the plug block is convex, and the plug groove matches the plug block.

[0010] The inverted convex plug-in block and the matching plug-in slot realize the lateral plug-in connection between adjacent unit cages. The connection method is simple, and the inverted convex structure can prevent the plug-in block from falling out of the plug-in slot. It can be quickly fixed and the replacement operation is also simple and quick.

[0011] As a preferred embodiment of the above technical solution, the end of the limiting plug is provided with an L-shaped protrusion, and the L-shaped protrusion of the limiting plug is movably inserted into the second slot.

[0012] The L-shaped protrusion at the end of the limiting plug can play a limiting role, preventing the limiting plug from sliding out of the second slot and improving the stability of the overall cage structure.

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

[0014] 1. Multiple unit cages are combined to form the cage frame. When a unit cage is damaged, only the corresponding unit cage needs to be replaced, without the need to replace the whole cage, which greatly reduces maintenance costs. In addition, the inverted convex plug-in block and the matching plug-in slot realize the lateral plug-in connection between adjacent unit cages. The connection method is simple, and the inverted convex structure can prevent the plug-in block from falling out of the plug-in slot. It can be quickly fixed and the replacement operation is also simple and quick.

[0015] 2. The limiting blocks are longitudinally inserted into the first and second slots of adjacent unit cages to restrict the lateral movement between unit cages. Together with the plug-in blocks, the two unit cages are connected and fixed, which further strengthens the connection strength between adjacent unit cages and makes the cage more stable during use. At the same time, the L-shaped protrusion at the end of the limiting blocks can play a limiting role to prevent the limiting blocks from sliding out of the second slot, thereby improving the overall stability of the cage structure.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0021] Figures 1-3 The replaceable bag filter cage includes: a unit cage and a fixing assembly corresponding to the unit cage. There are multiple unit cages. Each unit cage consists of a front support ring 11, a rear support ring 12, and multiple support rods 13. The front support ring 11 and the rear support ring 12 have the same diameter and are arranged in parallel. The fixing assembly includes two sets of plug-in blocks 21. There are two plug-in blocks 21 in the same set. The two sets of plug-in blocks 21 are fixedly connected to the end of the front support ring 11. The surface of the rear support ring 12 is provided with plug-in grooves 22 corresponding to the plug-in blocks 21. The unit cage moves laterally so that the plug-in blocks 21 on the front support ring 11 are laterally inserted into the plug-in grooves 22 of the rear support ring 12 of another unit cage to complete the cage connection.

[0022] The plug block 21 has an inverted convex cross section. The plug block 21 and the front support ring 11 are integrally formed. The plug groove 22 matches the plug block 21.

[0023] The cage frame is formed by combining multiple unit cages. When a unit cage is damaged, only the corresponding unit cage needs to be replaced, without the need for overall replacement, which greatly reduces maintenance costs. In addition, the inverted convex plug-in block 21 and the matching plug-in slot 22 realize the lateral plug-in connection between adjacent unit cages. The connection method is simple, and the inverted convex structure can prevent the plug-in block 21 from falling out of the plug-in slot 22. It can be quickly fixed and the replacement operation is also simple and quick.

[0024] Figures 1-3 In the process, the fixing component also includes two limiting blocks 23. The front support ring 11 has a first slot 24 on both sides, and the rear support ring 12 has a second slot 25 on both sides. The limiting blocks 23 are respectively inserted into the first slot 24 of the front support ring 11 and the second slot 25 of the rear support ring 12 of the other unit cage.

[0025] The end of the limiting plug 23 is provided with an L-shaped protrusion, and the L-shaped protrusion of the limiting plug 23 is movably inserted into the second slot 25.

[0026] The limiting plug 23 is longitudinally inserted into the first slot 24 and the second slot 25 of the adjacent unit cages to restrict the lateral movement between the unit cages. Together with the plug block 21, it connects and fixes the two unit cages, further strengthening the connection strength between the adjacent unit cages and making the cage more stable during use. At the same time, the L-shaped protrusion at the end of the limiting plug 23 can play a limiting role to prevent the limiting plug 23 from sliding out of the second slot 25, thereby improving the overall stability of the cage structure.

[0027] Working principle: Align the insertion slot 22 of the rear support ring 12 of the first unit cage with the insertion block 21 of the front support ring 11 of the second unit cage, and push the second unit cage laterally so that the insertion block 21 is inserted into the insertion slot 22. Then, insert one side of the limiting block 23 longitudinally into the second slot 25 of the rear support ring 12 of the first unit cage, and the other side into the first slot 24 of the front support ring 11 of the second unit cage. At the same time, make the L-shaped protrusion of the limiting block 23 engage in the second slot 25, thus completing the connection of the two unit cages. The inserted limiting block 23 restricts the lateral movement between the unit cages and, together with the insertion block 21, connects and fixes the two unit cages. In the same way, multiple unit cages can be connected as needed to form a cage of the required length.

[0028] When a unit cage is damaged and needs to be replaced, simply pull out the limiting block 23 between the unit cage and the adjacent unit cage, then move the unit cage laterally so that the plug block 21 comes out of the plug slot 22, and the damaged unit cage can be removed. After replacing it with a new unit cage, it can be reassembled.

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