Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, specifically to a low-resistance, low-leakage bag filter. Background Technology

[0002] A baghouse dust collector, also known as a fabric bag filter, is a dry dust filtration device that uses bag-shaped filter elements made of woven fabric to capture solid particles in dust-laden gas. The structure of a baghouse dust collector generally includes three parts: the bag chamber, the cleaning mechanism, and the dust hopper. Its advantages include high dust removal efficiency, a wide range of air volume handling capabilities, simple structure, convenient maintenance and operation, and lower cost than electrostatic precipitators.

[0003] Application number CN202423090350.X discloses a low-resistance, low-leakage baghouse dust collector. The main inlet flue is placed directly inside the middle housing of the dust collection module unit, with a direct opening serving as a branch inlet for the flue gas to enter the filter chamber. This reduces the complex external flue structure found in traditional designs, thereby lowering the resistance of the flue gas during transmission and reducing heat loss from the flue. The top of the flue chamber has installation holes for easy access to the filter bag assembly, and the side walls have manholes for easy maintenance. No other openable structures are included, further reducing leakage and minimizing the intrusion of low-temperature gases. However, this design still has shortcomings. The connection structure between the flue gas inlet and the flue pipe lacks flexibility, and misalignment during installation can lead to difficulties in connection, affecting installation efficiency and sealing.

[0004] Therefore, we propose a low-resistance, low-leakage bag filter. Utility Model Content

[0005] The main objective of this invention is to provide a low-resistance, low-leakage bag filter. By setting up a transfer pipe, a folding pipe, and an assembly mechanism, and utilizing the bendable characteristics of the folding pipe and the rotating connection structure of the assembly mechanism, the connection angle can be adjusted according to the actual installation position of the flue pipe, compensating for positional deviations during installation, avoiding installation difficulties caused by rigid connections, improving installation efficiency, and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A low-resistance, low-leakage baghouse dust collector includes a baghouse dust collector body, a transfer pipe, and a folded pipe. One end of the baghouse dust collector body has a smoke inlet. The transfer pipe is connected to the end of the baghouse dust collector body at the smoke inlet via a locking assembly. A connecting pipe is installed at the end of the transfer pipe away from the baghouse dust collector body via the folded pipe. The end of the connecting pipe away from the folded pipe is connected to one end of the smoke pipe. Assembly mechanisms are fitted at both ends of the folded pipe. Each assembly mechanism includes a first fastener and a second fastener.

[0008] A horizontal crossbar is provided above the folded tube. One end of the crossbar is vertically connected to the upper part of one side of the support rod. The bottom end of the support rod is connected to one of the assembly mechanisms through a socket. The end of the crossbar away from the support rod is provided with a connector for installing a connecting rod. The connecting rod is rotatably connected to the crossbar. The end of the connecting rod away from the crossbar is connected to another assembly mechanism through a socket.

[0009] By adopting the above technical solution, and by setting up a transfer pipe, a folding pipe and an assembly mechanism, the connection angle can be adjusted according to the actual installation position of the flue pipe by utilizing the bendable characteristics of the folding pipe and the rotating connection structure of the assembly mechanism, thus compensating for positional deviations during installation, avoiding installation difficulties caused by rigid connections, and improving installation efficiency.

[0010] Specifically, the locking assembly includes a first kit, a insert plate, a second kit, a plug, and a first bolt. The first kit is fixedly fitted onto one end of the adapter tube from top to bottom. The adapter tube has a plug inserted into the smoke inlet opening at the end away from the folded tube.

[0011] Specifically, the second kit is located on the upper part of the outside of the smoke inlet interface. The second kit is arranged parallel to the first kit. The top and both sides of the first kit near the second kit are vertically connected to insert plates.

[0012] Specifically, the second kit has a slot at one end near the first kit that is compatible with one end of the insert plate, and the second kit is fixedly connected to one end of the insert plate by the first bolt.

[0013] Specifically, two sets of sockets are arranged in parallel, and the two sets of sockets are respectively adapted to one end of the support rod and the connecting rod.

[0014] Specifically, the first fastener is fastened to the top of the second fastener. The bottom of the first fastener and the top of the second fastener are both provided with arc-shaped grooves that are adapted to the two ends of the folded tube. The first fastener and the second fastener are fastened to the two ends of the folded tube and fixedly connected by the second bolt.

[0015] The beneficial effects of this utility model are as follows: The low-resistance, low-leakage bag filter described in this utility model, by setting up a transfer pipe, a folding pipe, and an assembly mechanism, utilizes the bendable characteristics of the folding pipe and the rotating connection structure of the assembly mechanism (such as the rotating connection between the connecting rod and the crossbar) to adjust the connection angle according to the actual installation position of the flue pipe, compensate for positional deviations during installation, avoid installation difficulties caused by rigid docking, and improve installation efficiency; the crossbar, support rod, and connecting rod together form a triangular support structure, which is connected to the assembly mechanism through a socket, and can provide rigid support for the folding pipe, preventing it from excessively deforming or displacing due to flue gas pressure or its own weight, ensuring the stability and sealing of flue gas transmission; by inserting the insert plate into the slot and fixing it with the first bolt, the connection between the transfer pipe and the flue gas inlet is tighter, reducing the risk of leakage at the connection point, and further reducing the overall leakage rate of the dust collector.
