Description

Technical Field

[0001] The utility model relates to the technical field of filter bags, in particular to a combined filter bag that is easy to splice. Background Art

[0002] The filter bag is a key part in the operation of the bag dust collector. It has excellent chemical stability and heat resistance. It is the highest performance representative in the filter material industry and the highest performance variety among all commonly used filter materials. It has achieved a high level in terms of filtration efficiency and filtration accuracy.

[0003] For example, a combined installed filter bag disclosed in Chinese patent announcement number (CN210934178U) includes a filter bag fixing device and a filter bag device detachably connected to the filter bag fixing device; the filter bag fixing device is an inverted boss structure, a raised pipe is fixed on the bottom of the filter bag fixing device, and a hook is arranged on the outside of the pipe; a filter bag grid frame with a mesh structure is arranged inside the filter bag device; the filter bag grid frame with a built-in filter cloth supporting the filter bag device can improve the flexible structure of the filter bag into a rigid structure, which is convenient for vertical installation. At the same time, the filter bag device and the filter bag fixing device are a combined installation structure that can be double-fixed, the hook and the hook hanging hole are fixed by hanging, and the pipe and the pipe clamp are fixed by plugging. When disassembling and installing the two, only the connection between the hook and the hook hanging hole needs to be cancelled or fixed, and the disassembly, maintenance and cleaning can be carried out, which is convenient to use.

[0004] However, the above patent still has the problem of low efficiency in assembly and disassembly of the combined filter bag. For example, in the above patent, the connection between the hook and the hook hanging hole can be eliminated or fixed to perform disassembly, maintenance and cleaning. However, the filter bag needs to be connected to multiple hooks, which need to be disassembled one by one during assembly and disassembly, which greatly affects the splicing efficiency. In addition, the filter bag connected by the hook is prone to gaps outside the hook connection, which makes it impossible to completely filter the incoming air, affecting the filtering effect.
