Description

A bag cage for easy and quick installation and removal of filter bags Technical Field

[0001] This utility model relates to the field of bag cage technology, and in particular to a bag cage that facilitates quick installation and disassembly of filter bags. Background Technology

[0002] In pulse jet and box-type pulse jet dust collectors, dust adheres to the outer surface of the filter bags. When dust-laden gas passes through the dust collector, the dust is captured on the outer surface of the filter bags, while clean gas enters the interior. The bag cages inside the filter bags support them, preventing collapse, and also aid in the removal and redistribution of the dust cake. When installing the filter bags onto the bag cages, the connection between the cages and the filter bags is quite tight because the cages need to support and tighten the bags. This makes installation, disassembly, and cleaning of the filter bags very difficult. Forced installation or disassembly increases the probability of filter bag damage, affecting the filter bag's service life. Summary of the Invention

[0003] The purpose of this application is to provide a bag cage that facilitates quick installation and disassembly of filter bags, in order to solve the problem mentioned in the background art that when the filter bag is installed on the bag cage, the connection between the bag cage and the filter bag is relatively tight because the bag cage needs to support and tighten the filter bag. This makes it very difficult to install, disassemble and clean the filter bag. If the filter bag is forcibly disassembled, the probability of the filter bag being damaged will increase, affecting the service life of the filter bag.

[0004] To achieve the above objectives, this application provides the following technical solution: a bag cage for easy and quick installation and disassembly of filter bags, comprising a top ring and a transfer box, wherein the transfer box is located directly below the top ring, and a plurality of first extension tubes are fixedly arranged through the periphery of the transfer box, the plurality of first extension tubes being arranged in a circular array, two symmetrically arranged limiting rods being fixed to the inner wall of the first extension tubes, a first piston being slidably arranged inside the first extension tubes, a fixing block being fixed to the outer side of the first pistons, a limiting groove for sliding of the limiting rods being opened on the fixing block, a support rod being fixed to the upper surface of the fixing block, a T-shaped rod being fixed to the top end of the support rod, a sliding groove for sliding of the T-shaped rod being opened on the top ring, a water supply assembly being provided on the transfer box, and two reinforcing assemblies being provided between the support rod and the water supply assembly, the water supply assembly being used to adjust the water volume in the first extension tubes and the reinforcing assemblies, and the reinforcing assemblies being used to enhance the compressive strength of the support rod.

[0005] Furthermore, the water supply assembly includes a water supply pipe, the bottom end of which is connected to the transfer box, and a sealing plate is fixed to the top end of the water supply pipe.

[0006] Furthermore, the sealing plate is threaded with bolts, and the bottom end of the bolts is rotatably connected to a second piston via a bearing. The second piston slides in contact with the inner wall of the water supply pipe.

[0007] Furthermore, two water inlet pipes are fixedly connected through the water supply pipe, and valves are installed on the water inlet pipes.

[0008] Furthermore, the reinforcement component includes a second extension tube and a carrier block, one end of the second extension tube being connected to a water supply pipe, and the carrier block being fixedly sleeved on the outside of the support rod.

[0009] Furthermore, a third piston is slidably disposed inside the second extension tube, and a reinforcing rod is fixed to the outside of the third piston, with the carrier block fixedly mounted on the reinforcing rod.

[0010] In summary, the technical effects and advantages of this utility model are as follows:

[0011] 1. In this utility model, water is supplied to the inside of the first extension tube by the water supply component, which increases the water pressure inside the first extension tube. The water pressure can push the first piston in the first extension tube to slide outward, causing the fixing block to extend to the outside of the first extension tube. This causes several support rods to unfold outward, so that the support rods can support and tighten the filter bag. Similarly, after the water supply component draws water out of the first extension tube, the support rods will retract to the center. In this way, the loading and unloading of the filter bag on the bag cage becomes convenient, labor-saving and safe.

[0012] 2. In this utility model, a wrench is used to tighten the bolt, which adjusts the position of the second piston in the water supply pipe, forcing the second piston to regulate the water volume in the water supply pipe, thereby changing the water volume inside the first extension pipe, and thus controlling the expansion or contraction of the support rod; the water supply assembly can regulate the water volume inside the second extension pipe, allowing the third piston in the second extension pipe to slide inside the second extension pipe. The third piston can adjust the position of the carrier block with the help of the reinforcing rod. The carrier block is fixedly installed on the support rod, thus achieving reinforcement of the support rod position. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example: Referring to Figures 1-5, a filter bag cage for easy and quick installation and disassembly includes a top ring 1 and a transfer box 2. The transfer box 2 is located directly below the top ring 1. Multiple first extension tubes 3 are fixed through the periphery of the transfer box 2. The multiple first extension tubes 3 are arranged in a circular array. Two symmetrically arranged limiting rods 4 are fixed to the inner wall of the first extension tubes 3. A first piston 5 is slidably arranged inside the first extension tube 3. A fixing block 6 is fixed to the outer side of the first piston 5. A limiting groove 7 for sliding of the limiting rods 4 is opened on the fixing block 6. A support rod 8 is fixed to the upper surface of the fixing block 6. A T-shaped rod 9 is fixed to the top of the support rod 8. A sliding groove 10 for sliding of the T-shaped rod 9 is opened on the top ring 1. A water supply assembly is provided on the transfer box 2. Two reinforcing assemblies are provided between the support rod 8 and the water supply assembly. The water supply assembly is used to adjust the water volume in the first extension tubes 3 and the reinforcing assemblies. The reinforcing assemblies are used to enhance the compressive strength of the support rod 8.

[0022] Water is supplied to the inside of the first extension tube 3 by the water supply assembly, which increases the water pressure inside the first extension tube 3. The water pressure pushes the first piston 5 in the first extension tube 3 to slide outward, causing the fixing block 6 to extend outward of the first extension tube 3. This causes multiple support rods 8 to unfold outward, so that the multiple support rods 8 can support and tighten the filter bag. Similarly, after the water supply assembly removes the water from the first extension tube 3, the multiple support rods 8 will retract towards the center. With the cooperation of the limiting rod 4 and the limiting groove 7, the range of movement of the first piston 5 in the first extension tube 3 is limited. With the cooperation of the T-shaped rod 9 and the sliding groove 10, the range of outward expansion of the support rods 8 is limited, preventing the support rods 8 from over-tightening the filter bag and causing damage to the filter bag.

[0023] The water supply assembly includes a water supply pipe 11, the bottom end of which is connected to the transfer box 2. A sealing plate 12 is fixed to the top end of the water supply pipe 11. A bolt 13 is threaded onto the sealing plate 12. A second piston 14 is rotatably connected to the bottom end of the bolt 13 via a bearing. The second piston 14 slides against the inner wall of the water supply pipe 11. Two water inlet pipes 15 are fixed through the water supply pipe 11, and valves are installed on the water inlet pipes 15.

[0024] Using a wrench to tighten bolt 13, bolt 13 adjusts the position of the second piston 14 in the water supply pipe 11, forcing the second piston 14 to regulate the water volume in the water supply pipe 11, thereby changing the water volume inside the first extension pipe 3, and thus controlling the expansion or contraction of the support rod 8.

[0025] The reinforcement component includes a second extension tube 16 and a carrier block 17. One end of the second extension tube 16 is connected to the water supply pipe 11. The carrier block 17 is fixedly sleeved on the outside of the support rod 8. A third piston 18 is slidably arranged inside the second extension tube 16. A reinforcement rod 19 is fixed on the outside of the third piston 18. The carrier block 17 is fixedly installed on the reinforcement rod 19.

[0026] The water supply component can be used to regulate the water volume inside the second extension pipe 16, so that the third piston 18 in the second extension pipe 16 can slide inside the second extension pipe 16. The third piston 18 can adjust the position of the carrier block 17 with the help of the reinforcing rod 19. The carrier block 17 is fixedly installed on the support rod 8, so the position of the support rod 8 can be reinforced.

[0027] The working principle of this practical application is as follows:

[0028] Initially, the second piston 14 is pressed tightly against the sealing plate 12. At this time, the multiple support rods 8 are in a retracted state, and the staff can easily put the filter bag on the outside of the multiple support rods 8. After the filter bag is put on, the staff takes out a wrench and uses the wrench to turn the bolt 13, so that the bolt 13 pushes the second piston 14 down. As the second piston 14 squeezes the water in the water supply pipe 11 into the interior of the second extension pipe 16 and the transfer box 2, the water pressure inside the transfer box 2 increases, which will supply water to the first extension pipe 3, causing the third piston 18 to move to the outside of the second extension pipe 16 and the first piston 5 to move to the outside of the first extension pipe 3. In this way, the multiple support rods 8 are pushed outward to complete the support and tension of the filter bag.

[0029] During the filter bag lifting process, the fixing block 6 is limited by the limiting rod 4, and the T-shaped rod 9 is limited by the sliding groove 10, so that the range of the support rod 8 cannot be expanded after the filter bag is lifted, thus avoiding excessive tension on the filter bag. When the filter bag needs to be removed, the bolt 13 can be reversed with a wrench to move the second piston 14 upward. In this way, the water in the second extension pipe 16 and the first extension pipe 3 will flow back into the water supply pipe 11, and the multiple support rods 8 will retract towards the center, no longer tensioning the filter bag, making the removal of the filter bag more convenient.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
