Multi-segment adaptive telescopic bag cage assembly

Abstract

This utility model discloses a multi-segment adaptive telescopic bag cage assembly, including unit cages and a support assembly. Each unit cage consists of a front support ring, a rear support ring, and multiple support rods. The unit cage includes an outer unit cage and multiple inner unit cages. The support assembly is located on the inner unit cages and includes multiple connecting pieces. Each connecting piece is rotatably sleeved on the surface of the support rod of the corresponding inner unit cage, and a torsion spring is provided between the connecting piece and the support rod. The outer unit cage and multiple inner unit cages sequentially sleeved within the outer unit cage enable multi-segment telescopic movement of the bag cage assembly, allowing for flexible adjustment of the length according to actual needs. Under the action of the torsion spring, the connecting pieces in the support assembly can rotate out after the corresponding inner unit cage is pulled out to its final position, effectively supporting the pulled-out inner unit cage and preventing it from retracting inward, thus ensuring the structural stability of the bag cage assembly during use.

Description

Technical Field

[0001] This utility model belongs to the technical field of bag dust collectors, and in particular relates to a multi-segment adaptive telescopic bag cage assembly. 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] Traditional bag cages are long, bulky, and non-foldable, making them inconvenient to store and transport. Utility Model Content

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

[0005] A multi-segment adaptive telescopic bag cage assembly includes: a unit cage and a support assembly. The unit cage consists of a front support ring, a rear support ring and multiple support rods. The unit cage includes an outer unit cage and multiple inner unit cages, and the multiple inner unit cages are sequentially nested inside the outer unit cage.

[0006] The support assembly is located on multiple inner unit cages. The support assembly includes multiple connecting pieces. The connecting pieces are rotatably sleeved on the surface of the support rod of the corresponding inner unit cage, and the end of the connecting piece is flush with the surface of the support rod of the outer unit cage. A torsion spring is provided between the connecting piece and the support rod.

[0007] As a preferred embodiment of the above technical solution, the support rods of the inner unit cage are staggered with the support rods of the adjacent inner unit cages or the support rods of the outer unit cages.

[0008] As a preferred embodiment of the above technical solution, the front support ring and the rear support ring of the same unit cage are of the same size.

[0009] As a preferred embodiment of the above technical solution, the surface of the front support ring of the inner unit cage is provided with a flush ring, the outer diameter of the multiple flush rings is the same, and the outer surface of the multiple flush rings is flush with the surface of the front support ring of the outer unit cage.

[0010] As a preferred embodiment of the above technical solution, the rear support ring surface of the plurality of inner unit cages is provided with a plurality of limiting protrusions, one set of the limiting protrusions being in contact with the support rod surface of the outer unit cage, and the remaining plurality of the limiting protrusions being in contact with the connecting piece surface on the outer inner unit cage.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The outer unit cage and multiple inner unit cages nested sequentially within the outer unit cage enable multi-segment telescopic design of the bag cage assembly, allowing for flexible adjustment of the usage length according to actual needs. Under the action of a torsion spring, the connecting plate in the support assembly can rotate out after the corresponding inner unit cage is pulled out to its designated position, effectively supporting the pulled-out inner unit cage and preventing it from retracting inward. This ensures the structural stability of the bag cage assembly during use. Furthermore, both the connecting plate and the flush ring are flush with the surface of the support rod of the outer unit cage, effectively ensuring the neatness of the entire telescopic bag cage assembly after it is pulled out, thus improving the overall performance of the bag cage assembly.

[0013] 2. The support rods of the inner unit cage are staggered with the support rods of the adjacent inner unit cages or the support rods of the outer unit cages, which can be used to block the connecting pieces to complete the storage of the bag cage assembly. Attached Figure Description

[0018] 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.

[0019] Figures 1-3 In the middle, the multi-segment adaptive telescopic bag cage group includes: unit cage and support assembly. The unit cage is composed of front support ring 10, rear support ring 20 and multiple support rods 30. The unit cage includes an outer unit cage and multiple inner unit cages, and the multiple inner unit cages are sequentially nested inside the outer unit cage.

[0020] The support assembly is located on multiple inner unit cages. The support assembly includes multiple connecting pieces 40. The connecting pieces 40 are rotatably sleeved on the surface of the support rod 30 of the corresponding inner unit cage, and the end of the connecting piece 40 is flush with the surface of the support rod 30 of the outer unit cage. A torsion spring is provided between the connecting piece 40 and the support rod 30.

[0021] The outer unit cage and multiple inner unit cages nested sequentially within it enable multi-segment telescopic movement of the bag cage assembly, allowing for flexible adjustment of the usage length according to actual needs. The connecting piece 40 in the support assembly, under the action of a torsion spring, can rotate out after the corresponding inner unit cage is pulled out to its designated position, becoming flush with the surface of the support rod 30 of the outer unit cage. This effectively supports the pulled-out inner unit cage, preventing it from retracting inward and ensuring the structural stability of the bag cage assembly during use.

[0022] Figures 1-3 In this configuration, the support rods 30 of the inner unit cage are staggered with the support rods 30 of adjacent inner unit cages or outer unit cages.

[0023] The support rods 30 of the inner unit cage are staggered with the support rods 30 of the adjacent inner unit cage or the support rods 30 of the outer unit cage, so that the bag cage assembly can be stored by blocking the connecting piece 40.

[0024] Figures 1-3 In the same unit cage, the front support ring 10 and the rear support ring 20 are the same size.

[0025] The inner unit cage has a front support ring 10 with a flush ring on its surface. The outer diameter of the multiple flush rings is the same, and the outer surface of the multiple flush rings is flush with the surface of the outer unit cage's front support ring 10.

[0026] The rear support ring 20 of each of the multiple inner unit cages is provided with multiple limiting protrusions 50. One set of the limiting protrusions 50 is in contact with the surface of the support rod 30 of the outer unit cage, and the other sets of the limiting protrusions 50 are in contact with the surface of the connecting piece 40 on the outer inner unit cage.

[0027] Both the connecting piece 40 and the flush ring are flush with the surface of the support rod 30 of the outer unit cage, which can effectively ensure the neatness of the entire telescopic bag cage assembly after it is pulled out, and improve the overall performance of the bag cage assembly.

[0028] Working principle: When assembling the bag filter, first assemble the telescopic bag cage assembly. The front support ring 10 of the entire inner unit cage is moved by the flushing ring. When the limiting protrusion 50 contacts the adjacent rear support ring 20, the corresponding inner unit cage is fully pulled out. At this time, the connecting piece 40 is in a free state and is no longer blocked by the adjacent connecting piece 40 or the support rod 30 of the outer unit cage. The torsion spring in a torsional state rotates the connecting piece 40 out, making it flush with the surface of the support rod 30 of the outer unit cage. With the use of the flushing ring, the "neatness" of the entire telescopic bag cage assembly is ensured. The torsional connecting piece 40 supports the pulled-out inner unit cage and will not retract inward. It can only push multiple connecting pieces 40 away from the limiting position when storing. At the same time, bolts or other fixing methods can be used to fix the inner unit cage that does not need to be pulled out, thereby adjusting the length of use.

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