Description

Technical Field

[0001] This utility model relates to the field of oil separator technology, specifically to an anti-deformation structure for an oil separator filter screen. Background Technology

[0002] Oil separators play a crucial role in industrial production, refrigeration systems, and automotive engines. They intercept and separate oil droplets from oil-gas mixtures through filters to ensure gas purity and stable system operation. As the core component of the oil separator, the performance of the filter directly affects the oil separation efficiency and the service life of the equipment.

[0003] However, traditional oil separator filters are mostly simple planar or single-layer mesh structures with weak rigidity. When subjected to high-speed airflow impact or oil pressure fluctuations, they are prone to dents, wrinkles, or even breakage and deformation. In refrigeration systems, the pressure changes during startup and shutdown often cause the filter to deform due to the pressure impact, resulting in larger filter pores, reduced separation efficiency, or even loss of separation function. Therefore, there is an urgent need for an anti-deformation structure for oil separator filters to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant structure for oil separator filter screens, so as to solve the problem mentioned in the background art that traditional oil separator filter screens are prone to dents, wrinkles or even damage and deformation when subjected to high-speed airflow impact or oil pressure fluctuations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter screen anti-deformation structure for an oil separator, comprising a main body, wherein a filter screen is fixedly connected to the inner wall of the main body, and a support component is provided inside the main body;

[0006] The support assembly includes a sliding column, which is slidably connected to the inner wall of the main body. A movable frame is slidably connected to the surface of the sliding column, and a plurality of first connecting blocks are fixedly connected to the surface of the movable frame. A connecting rod is rotatably connected to the inner wall of the first connecting block, and a second connecting block is rotatably connected to the surface of the connecting rod. The side walls of two second connecting blocks are fixedly connected to the same support plate, and the surfaces of the plurality of support plates abut against the inner wall of the filter screen.

[0007] Preferably, the inner wall of the movable frame is provided with a plurality of sliding holes, and the inner walls of the plurality of sliding holes are slidably connected to the same sliding frame. The inner wall of the sliding frame is fixedly connected to the surface of the sliding column, and a compression spring is fixedly connected to the bottom surface of the sliding frame. The lower end of the compression spring abuts against the inner wall of the movable frame.

[0008] Preferably, the top surface of the main body is detachably connected to a fixing box by bolts, and the inner wall of the fixing box is threaded with a threaded post, the lower end of the threaded post abutting against the upper end of the sliding post.

[0009] Preferably, an outer support box is fixedly connected to the inner wall of the main body, and the inner wall of the outer support box abuts against the surface of the filter screen.

[0010] Preferably, a nut is threaded onto the surface of the threaded post, and the lower end of the nut abuts against the upper end of the fixing box.

[0011] Preferably, the surface of the outer support box is provided with multiple arc-shaped holes, and the multiple arc-shaped holes are matched in size.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Multiple support plates are positioned on the inner wall of the filter screen via a set support assembly. The downward movement of the movable frame, through the cooperation of the first connecting block, connecting rod, and second connecting block, pushes the multiple support plates outward, allowing their surfaces to press against the inner wall of the filter screen and support it. This prevents deformation of the filter screen surface when subjected to high airflow impact or oil pressure fluctuations. Simultaneously, the sliding column, movable frame, and compression spring work together. When the sliding column moves downward, it drives the sliding frame to move. The movement of the sliding frame compresses the compression spring, causing it to deform and apply force to the movable frame, thus moving it downward. This buffers the downward pressure from the sliding column, preventing rigid contact between the multiple support plates and the inner wall of the filter screen, and improving the stability of the support plates in supporting the filter screen.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a filter screen anti-deformation structure for an oil separator, including a main body 1. A filter screen 2 is fixedly connected to the inner wall of the main body 1. A support assembly 3 is provided inside the main body 1. The support assembly 3 includes a sliding column 301, which is slidably connected to the inner wall of the main body 1. A movable frame 302 is slidably connected to the surface of the sliding column 301. A plurality of first connecting blocks 306 are fixedly connected to the surface of the movable frame 302. A connecting rod 307 is rotatably connected to the inner wall of the first connecting block 306. A second connecting block 308 is rotatably connected to the surface of the connecting rod 307. Two second connecting blocks 308... The side wall of block 308 is fixedly connected to the same support plate 309. The surfaces of multiple support plates 309 abut against the inner wall of filter screen 2. Through the support assembly 3, multiple support plates 309 are set on the inner wall of filter screen 2, so that the moving frame 302 moves downward. The first connecting block 306, the connecting rod 307 and the second connecting block 308 work together to push multiple support plates 309 outward, so that the surfaces of multiple support plates 309 abut against the inner wall of filter screen 2 to support filter screen 2 and avoid deformation of the surface of filter screen 2 when high airflow impact or oil pressure fluctuation.

[0022] Furthermore, the inner wall of the movable frame 302 is provided with multiple sliding holes 303, and the inner walls of the multiple sliding holes 303 are slidably connected to the same sliding frame 304. The inner wall of the sliding frame 304 is fixedly connected to the surface of the sliding column 301, and a compression spring 305 is fixedly connected to the bottom surface of the sliding frame 304. The lower end of the compression spring 305 abuts against the inner wall of the movable frame 302. Through the cooperation of the sliding column 301, the movable frame 302 and the compression spring 305, the sliding column 301 moves downward, causing the sliding frame 304 to move. The movement of the sliding frame 304 compresses the compression spring 305, causing the compression spring 305 to deform and apply force to the movable frame 302, thereby causing the movable frame 302 to move downward. This facilitates the buffering of the downward compression force of the sliding column 301, avoids rigid contact between the multiple support plates 309 and the inner wall of the filter screen 2, and improves the stability of the multiple support plates 309 supporting the filter screen 2.

[0023] Furthermore, a fixed box 312 is detachably connected to the top surface of the main body 1 by bolts. A threaded post 313 is threadedly connected to the inner wall of the fixed box 312. The lower end of the threaded post 313 abuts against the upper end of the sliding post 301. The fixed box 312 and the threaded post 313 cooperate with each other. The surface of the threaded post 313 is threadedly connected to the inner wall of the fixed box 312, so that rotating the threaded post 313 can easily press the lower end of the threaded post 313 against the upper end of the sliding post 301, thereby facilitating easy adjustment of the support force of the multiple support plates 309.

[0024] Furthermore, an outer support box 310 is fixedly connected to the inner wall of the main body 1. The inner wall of the outer support box 310 abuts against the surface of the filter screen 2. The outer support box 310 facilitates the support of the surface of the filter screen 2, thereby facilitating the connection of the support force of the multiple support plates 309.

[0025] Furthermore, a nut 314 is threadedly connected to the surface of the threaded post 313. The lower end of the nut 314 abuts against the upper end of the fixing box 312. The nut 314 facilitates the fixing of the threaded post 313 after adjustment, thereby improving the stability of the support.

[0026] Furthermore, the surface of the outer support box 310 is provided with multiple arc-shaped holes 311, the multiple arc-shaped holes 311 are matched in size, and the multiple arc-shaped holes 311 are provided to avoid obstructing the filtering effect of the filter screen 2.

[0027] Working principle: Multiple support plates 309 are mounted on the inner wall of the filter screen 2 via the support assembly 3. The downward movement of the movable frame 302, through the cooperation of the first connecting block 306, connecting rod 307, and second connecting block 308, pushes the multiple support plates 309 outward. This allows the surfaces of the support plates 309 to abut against the inner wall of the filter screen 2, supporting it and preventing deformation of the filter screen 2 due to high airflow impact or oil pressure fluctuations. Simultaneously, the sliding column 301, movable frame 302, and compression spring 305 work together. When the sliding column 301 moves downward, it drives the sliding frame 304 to move, and the movement of the sliding frame 304 compresses the compression spring 305. The compression spring 305 deforms and applies force to the movable frame 302, causing the movable frame 302 to move downward. This facilitates the buffering of the downward compression force of the sliding column 301, preventing rigid contact between the multiple support plates 309 and the inner wall of the filter screen 2, and improving the stability of the multiple support plates 309 in supporting the filter screen 2. Secondly, the fixed box 312 and the threaded column 313 work together. The surface of the threaded column 313 is threaded to the inner wall of the fixed box 312, so rotating the threaded column 313 allows the lower end of the threaded column 313 to be compressed against the upper end of the sliding column 301, thus facilitating easy adjustment of the support force of the multiple support plates 309.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
