Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration equipment, specifically a filtration device for a dust removal pipeline. Background Technology
[0002] A lot of dust is generated during the feeding process of raw materials, so a dust removal device is often installed at the feeding port. The dust removal device can suck the dust out from the feeding port. The dust removal device at the feeding port can draw away the air at the feeding port through the fan, so that the dust at the feeding port is drawn into the dust removal pipe with the air under the action of negative pressure, and then enters the fan chamber with the dust removal pipe, thereby removing the dust raised at the feeding port.
[0003] According to the existing patent document CN215782300U, a filtration device for a dust removal pipeline includes a filter pipe and a filter section. The filter section is located inside the filter pipe and is coaxially arranged with the filter pipe. The filter section includes filter blades that are rotatably connected to the filter pipe. Filter sponges are provided on the filter blades. Fixed seats are provided at both ends of the filter pipe. A spring is fixedly connected to the end of the fixed seat away from the filter section. Snap-fit rings are fitted at both ends of the filter pipe. One end of the snap-fit ring is snapped onto the side of the fixed seat away from the spring, and the other end is fitted onto the dust removal pipe and fixedly connected to the spring. In use, under the action of the wind force in the dust removal pipe, the filter blades are blown to rotate, and the filter blades drive the filter sponge to rotate. During the rotation, the filter sponge intercepts dust in the dust removal pipe and adsorbs the dust onto the filter sponge, thereby filtering out the dust in the wind and reducing the amount of dust entering the fan chamber. Regarding the above technical solution, although this solution reduces the amount of dust, it cannot perform double filtration of dust during use, which is inconvenient. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a filtration device for dust removal pipelines, thereby solving the problems mentioned in the background art. This utility model has a novel structure. In use, it performs initial filtration through the filtration components. Later, when the filtration components are completely blocked, the airflow is filtered and discharged through the filter plate on the through hole, thus realizing the alternating operation of the filtration points and effectively increasing the filtration time of the equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for a dust removal pipeline, comprising a pipeline, a filter cylinder fixedly installed between the pipelines, fixed columns welded to both ends of the filter cylinder, a ring seat movably installed on the fixed column, an opening in the ring seat, the fixed column movably installed inside the opening, a fixing bolt rotatably installed on the ring seat, and an annular grooves opened at both ends of the filter cylinder, with a sealing ring fixed on the inner wall of the annular groove.
[0006] Furthermore, the sealing ring contacts the outer wall of the pipe, and a washer is fixed inside the ring groove, with the washer in movable contact with one end of the pipe.
[0007] Furthermore, a limiting ring is fixed on the inner wall of the filter cylinder, and a rotating seat is movably installed between the limiting rings. The rotating seat is installed inside the filter cylinder via a bearing.
[0008] Furthermore, a filter assembly and a rotating column are fixedly installed on the rotating base, and a fan blade is fixedly installed on the rotating column.
[0009] Furthermore, a fixing frame is welded to the inner wall of the filter cartridge, and a scraper is welded to one end of the fixing frame, the scraper being in contact with the filter assembly.
[0010] Furthermore, a through hole is formed on the inner wall of the filter cylinder, and a filter plate is fixedly installed inside the through hole.
[0011] Furthermore, one end of the through hole has an air cavity, and one end of the air cavity has an air outlet, which is installed on one side of the rotating seat.
[0012] Furthermore, both the ring seat and the fixing post have threaded holes, and the fixing bolt is rotatably installed inside the threaded holes.
[0013] The beneficial effects of this utility model are:
[0014] 1. The dust removal pipeline filtration device performs initial filtration through the filter components during use. Later, when the filter components are completely clogged, the airflow is filtered and discharged through the filter plate on the through hole, thereby realizing the alternating operation of the filtration points and effectively increasing the filtration time of the equipment.
[0015] 2. In this dust removal duct filtration device, the filter cartridge is mounted on a ring seat via a fixing column. The ring seat and the fixing column cooperate to provide a large area of fixed support for the filter cartridge. During subsequent installation of the filter cartridge, the fixing column and the ring seat cooperate to achieve rapid positioning and installation.
[0016] 3. In this dust removal duct filtration device, the airflow drives the fan blades to rotate, and the rotation of the fan blades drives the rotating seat to rotate. The rotation of the rotating seat cooperates with the scraper, and the scraper scrapes off the dust on the surface of the filter component, thereby effectively preventing the filter component from clogging.

A fixing frame 13 is welded on the inner wall of the filter cylinder 2, and a scraper 14 is welded to one end of the fixing frame 13. The scraper 14 is in contact with the filter assembly 12, which is a filter screen that filters dust in the airflow.
[0025] In this embodiment, a through hole 17 is opened on the inner wall of the filter cylinder 2, and a filter plate 18 is fixedly installed inside the through hole 17. An air cavity 19 is opened at one end of the through hole 17, and an air outlet 20 is opened at one end of the air cavity 19. The air outlet 20 is installed on one side of the rotating seat 10. Threaded holes are opened on both the ring seat 3 and the fixing column 4. The fixing bolt 6 is rotatably installed inside the threaded hole. The fixing bolt 6 passes through the threaded hole and contacts the outer wall of the pipe 1. The fixing and limiting of the ring seat 3 is achieved by the extrusion force of the fixing bolt 6.
[0026] In use, the ring seat 3 is movably installed on the pipe 1. After the ring seat 3 is installed, the filter cartridge 2 is installed between the pipes 1. One end of the pipe 1 is installed inside the annular groove 7. The washer 9 is in movable contact with one end of the pipe 1.
