Description

Technical Field

[0001] This utility model belongs to the technical field of bag dust collectors, and particularly relates to a multi-section folding bag cage device. 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] Bag cages typically consist of support rings and connecting rods between them. However, traditional bag cages are long, bulky, and non-foldable, making them inconvenient to store and transport, and extremely difficult to use. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution: A multi-segment folding bag cage device includes: multiple support rings, and multiple connectors between adjacent support rings. Each connector consists of a central block and two retractable rods. One end of each retractable rod is rotatably inserted into the central block, and the other end is rotatably inserted into the support ring. When the support rings move, the two retractable rods rotate toward the center of the support ring from the insertion point of the central block. The two retractable rods fold to retract the entire bag cage device.

[0005] As a preferred embodiment of the above technical solution, a fixing component is provided inside the support ring. The fixing component includes two movable rings, and a spring is fixedly connected between the two movable rings. A stop block is provided at each of the movable rings at multiple retractable rod positions.

[0006] As a preferred embodiment of the above technical solution, the bottom of the stop block is in contact with the surface of the retractable rod, and the stop block is used to prevent the retractable rod from deflecting toward the center of the support ring.

[0007] As a preferred embodiment of the above technical solution, the fixing component further includes two blocking blocks, which are fixedly connected to the support ring by screws. The blocking blocks have sloping sides, and the contact points of the moving ring match them.

[0008] The beneficial effects of this utility model are as follows: 1. The connecting parts between the support rings consist of a central block and two retractable rods. The retractable rods are rotatably inserted into the central block and the support ring respectively. When the support ring moves, the two retractable rods can rotate towards the center of the support ring from the insertion point of the central block, realizing the folding and retraction of the entire bag cage device, which greatly reduces the volume of the bag cage device and facilitates transportation and storage. 2. By utilizing the cooperation between the blocking block and the support ring, the two moving rings move in opposite directions when the blocking block is inserted. The blocking block then extends out from inside the support ring until it fits against the surface of the retractable rod. This prevents the retractable rod from deflecting towards the center of the support ring, ensuring that the bag cage device will not fold accidentally during use and improving its stability.

[0011] 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.

[0012] Figures 1-4 The multi-segment folding bag cage device includes: multiple support rings 10, and multiple connectors 20 between adjacent support rings 10. Each connector 20 consists of a central block 21 and two retractable rods 22. One end of each retractable rod 22 is rotatably inserted into the central block 21, and the other end is rotatably inserted into the support ring 10. When the support ring 10 moves, the two retractable rods 22 rotate towards the center of the support ring 10 with respect to the insertion point of the central block 21. The two retractable rods 22 fold to retract the entire bag cage device.

[0013] The connecting piece 20 between the support rings 10 consists of a central block 21 and two retractable rods 22. The retractable rods 22 are rotatably inserted into the central block 21 and the support ring 10 respectively. When the support ring 10 moves, the two retractable rods 22 can rotate towards the center of the support ring 10 from the insertion point of the central block 21, realizing the folding and shrinking of the entire bag cage device, which greatly reduces the volume of the bag cage device and facilitates transportation and storage.

[0014] Figures 1-4In the middle, the support ring 10 is provided with a fixing component 30, the fixing component 30 includes two moving rings 31, and a spring 32 is fixedly connected between the two moving rings 31. Each moving ring 31 is provided with a stop block 33 at the position of a plurality of retractable rods 22.

[0015] The bottom of the stop block 33 is in contact with the surface of the retractable rod 22, and the stop block 33 is used to prevent the retractable rod 22 from deflecting toward the center of the support ring 10.

[0016] The fixing component 30 also includes two blocking blocks 34, which are fixedly connected to the support ring 10 by screws or other fixing methods. The two sides of the blocking block 34 are set with slopes, and the contact point of the moving ring 31 matches it.

[0017] By utilizing the cooperation between the blocking block 34 and the support ring 10, the two moving rings 31 move in opposite directions when the blocking block 34 is inserted. The abutment block 33 then extends out from inside the support ring 10 until it fits against the surface of the retractable rod 22. This prevents the retractable rod 22 from deflecting toward the center of the support ring 10, ensuring that the bag cage device will not fold accidentally during use and improving the stability of use.

[0018] Working principle: When using the bag cage device, because the two sides of the blocking block 34 are set with slopes and the contact point of the moving ring 31 matches it, pushing the blocking block 34 will move the two moving rings 31 in opposite directions. The spring 32 in its natural state will be stretched and deformed. Due to the movement of the moving ring 31, the corresponding blocking block 33 will extend out from the inside of the support ring 10 until the surface of the blocking block 33 is in contact with the surface of the shrinking rod 22. The shrinking rod 22 will deflect towards the center of the support ring 10, and after the blocking block 34 is fixed, the bag cage device will be in the unfolded state, stably supporting the filter bag. When the bag cage device needs to be folded and retracted, the fixing of the blocking block 34 is removed and pulled out. Under the action of the spring 32's restoring force, the two moving rings 31 move towards each other. The blocking block 33 moves away from the retracting rod 22 as the moving rings 31 move. At this time, the retracting rod 22 is no longer blocked, pushing the support ring 10 to move. The two retracting rods 22 rotate towards the center of the support ring 10 around the insertion point of the center block 21, realizing folding and retracting the entire bag cage device for easy transportation and storage.

[0019] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
