Description

Technical Field

[0001] This utility model relates to the technical field of dustproof bag disassembly and assembly auxiliary devices, and in particular to an easy-to-close and disassemble dustproof bag. Background Technology

[0002] A baghouse dust collector is a dry dust collection device, the core component of which is the filter bag. These bags are typically made of woven filter cloth or non-woven adhesive materials, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, large, heavy dust particles settle due to gravity and fall into the ash hopper; while gas containing finer dust particles passes through the filter media, where the dust is trapped, thus purifying the gas.

[0003] In existing baghouse dust collectors, the dust bag interface adopts a fixed structure design, and the bag port adopts an open structure, which is not convenient for closing or sealing operations. During the bag disassembly process, dust is easily spilled out, causing a dirty and messy working environment. Therefore, it is particularly important to design an easy-to-close and disassemble dust bag to solve the above technical problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of fixed structure design of dust bag interface in existing bag dust collectors, open structure of bag port which is not convenient for closing operation or sealing operation, and dust overflow during bag disassembly, resulting in a dirty and messy working environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an easy-to-close and detachable dustproof bag, comprising an outlet pipe, a connecting pipe movably connected below the outlet pipe, a box installed at the bottom of the connecting pipe, a cloth bag installed at the bottom of the box, the cloth bag communicating with the box, an external thread provided on the outer wall of the connecting pipe, an internal thread provided on the inner wall of the outlet pipe, the connecting pipe being threadedly connected to the outlet pipe at the position, an insert plate slidably connected in the box, and the cross-section of the connecting pipe being a tubular structure.

[0006] Preferably, the outer wall of the connector has mounting holes evenly distributed circumferentially, and the connector is threadedly connected to the outlet pipe by fasteners.

[0007] Preferably, a limiting plate is fixedly connected to the insert plate, and the limiting plate is connected to the outer wall of the box by a spring, which is made of a high-resilience material.

[0008] Preferably, the housing is provided with a sliding groove, and the insert rod is fitted with the shape of the sliding groove.

[0009] Preferably, a retaining plate is movably connected to the insert plate, the retaining plate is disposed between the limiting plate and the outer wall of the box, and the relative position of the retaining plate does not interfere with the spring.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, during use, a box structure is set between the cloth bag and the connecting pipe, and an insert plate structure is slidably set in the box. Simultaneously, a sliding groove structure that matches the insert plate is provided in the box, allowing the insert plate to guide its movement within the groove. When the cloth bag is in operation, a locking plate structure is installed on the outer wall of the insert rod, limiting the insertion of the insert rod between the limiting plate and the outer wall of the box. At this time, the spring is in a stretched state, and the relative positions of the locking plate and the spring do not interfere with each other. Compared to conventional cloth bags, the opening is less prone to closing. The technical solution adopted by this utility model allows for quick disassembly of the connecting pipe at the outlet pipe position. A sliding insert plate structure is then installed in the housing to seal the open portion of the filter bag, preventing dust overflow and secondary pollution of the working environment. The overall structure is compact and the spatial layout is reasonable. This solves the problems of existing baghouse dust collectors where the dust bag interface uses a fixed structure design, the filter bag port is open, making it inconvenient to close or seal the opening, and dust easily overflows during filter bag disassembly, resulting in a dirty and messy working environment.

[0012] 2. In this utility model, during use, the sliding groove structure that matches the insert plate is provided in the box body, so that the insert plate plays a guiding role when sliding in the sliding groove. Attached Figure Description
