Description

Technical Field

[0001] The present application relates to the technical field of pipeline filters, and in particular to a pipeline filter screen. Background Art

[0002] Pipeline filter, a hydraulic term, is a filter used for the pipeline part of the hydraulic system. Pipeline filter is a filter involved in the pipeline transportation process. Pipeline filter is mainly composed of a pipe, a cylinder, a filter basket, a flange, a flange cover and fasteners. It is installed on the pipeline to remove larger solid impurities in the fluid, so that machinery and equipment (including compressors, pumps, etc.) and instruments can work and operate normally, achieve a stable process, and ensure safe production.

[0003] The existing patent (publication number: CN220214217U) discloses a pipeline filter and a pipeline filter device. It solves the problem that the existing pipeline filter cannot perform good filtering and cleaning, and the pipeline filter installed in the air delivery pipe needs to be removed as a whole. The pipeline filter includes a filter body and a filter screen that can be detachably installed in the filter body. An opening is opened on the side wall of the filter body, and a filter screen track is provided in the filter body. The filter screen is installed on the filter screen track. An open and closed filter cover is hinged on the side wall of the filter body. The filter screen has a matching side surface that matches the inner surface of the filter cover in the circumferential direction, and a filter cover locking mechanism is provided between the filter cover and the filter body. Advantages of this application: It solves the problem that the pipeline filter cannot perform good filtering and cleaning, and filtering and cleaning can be achieved without removing the pipeline filter as a whole, which reduces production costs, and at the same time, improves the quality and efficiency of filtration.

[0004] During the use of the above-mentioned document, a large number of bolts and nuts are used. Special tools are required to remove the filter. Disassembly requires removing multiple bolts one by one, which is slow and inconvenient for replacing the filter. Utility Model Content

[0007] Through the above solution, the installed spring can push the block to reset through the deformation force of the spring. When the block is pulled out, the first frame, the conical filter screen and the second frame can be separated, which is convenient for replacing the conical filter screen.

[0008] Furthermore, the upper surfaces of the plurality of blocks are all configured to be arc-shaped.

[0009] Through the above solution, the upper end of the card block is set to an arc shape to facilitate contact with the top block to push the card block to slide in the card slot, so that the first frame, the conical filter screen, and the second frame can be stably connected together.

[0010] Furthermore, the plurality of top blocks are all configured to be arc-shaped.

[0012] Furthermore, the plurality of springs are all in a compressed state.

[0013] Through the above solution, the installation spring can eject the card block through the deformation force of the spring after the top block is separated from the card block, which is convenient for removing the card block and enables the first frame, the conical filter screen and the second frame to be separated.

[0014] Furthermore, two groups of limiting teeth are fixedly connected to the inner wall of the rotating ring, and two elastic baffles are fixedly connected to the upper surface of the second frame, and both of the two elastic baffles are in contact with the limiting teeth adjacent to them.

[0016] Furthermore, a protective frame is clamped on the upper surface of the second frame.

[0017] Through the above solution, installing the protection frame can prevent impurities in the pipe body from entering the connection between the first frame, the conical filter screen and the second frame, thereby avoiding affecting the connection between the first frame, the conical filter screen and the second frame.

[0018] Furthermore, the first frame is connected to the inner wall of the tube body by bolts.

[0019] Through the above solution, the first frame can be made more stable by connecting the first frame and the tube body together using bolts, so that the first frame can stably support the conical filter.

[0020] Furthermore, the first frame, the conical filter screen and the second frame are in close contact with each other.

[0021] Through the above solution, the close contact between the first frame, the conical filter screen and the second frame can make the conical filter screen more stable and facilitate filtering of impurities.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The filter screen of the pipeline filter can fix the first frame, the conical filter screen and the second frame together during the sliding process of the card block by means of the cooperation between the installation card block and the card slot; when the conical filter screen is to be disassembled, the second frame and the conical filter screen can be disassembled by reversing the rotating ring, so that they are easy to replace; installation and disassembly can be completed by only rotating the rotating ring, and the use is convenient and quick.

[0033] See also Figure 1 , Figure 2 and Figure 4A protective frame 12 is clamped on the upper surface of the second frame 4. Installing the protective frame 12 can prevent impurities in the tube body 1 from entering the connection between the first frame 2, the conical filter screen 3, and the second frame 4, and avoid affecting the connection between the first frame 2, the conical filter screen 3, and the second frame 4. The first frame 2 is connected to the inner wall of the tube body 1 by bolts. By using bolts to connect the first frame 2 and the tube body 1 together, the first frame 2 can be made more stable, so that the first frame 2 can stably support the conical filter screen 3.

At this time, the top block 9 and the clamping block 6 are separated, and the deformation force of the spring 7 will push the clamping block 6 to reset at this time. Then, the clamping block 6 can be taken out to separate the first frame 2, the conical filter 3, and the second frame 4, so as to facilitate the replacement of the conical filter 3.
