Description

Technical Field

[0001] The utility model relates to the technical field of filter protection, in particular to an air filter protection structure. Background Technique

[0002] A filter is an indispensable device on the conveying medium pipeline, usually installed on a pressure reducing valve, a pressure relief valve, and a constant water level valve. The filter cartridge with a certain specification filter screen in the filter can block impurities. Filters can generally be divided into liquid filters and air filters. The air often contains a lot of impurities. General air filters filter the impurities in the air through a filter screen. After the filter screen is used for a period of time, its mesh will be blocked, and then the filter screen needs to be replaced. The existing filter screens are generally fixed by fixing screws, which will make it inconvenient to replace the filter screen, reduce the replacement efficiency of the filter screen, and the long-term tightening and loosening of the screws will affect the service life of the screws. Therefore, we propose an air filter protection structure to solve the above problems. Content of the Utility Model

[0023] Embodiment

[0024] Please refer to Figures 1-4 , an air filter protection structure, including an air filter 1. An intake pipe 2 is connected and installed at the input end of the air filter 1, and an exhaust pipe 3 is connected and installed at the output end of the air filter 1. A support 4 is fixedly installed at the inner bottom end of the intake pipe 2. A fixing groove 5 is formed at the top end of the support 4. A filter screen plate 6 is slidably installed inside the fixing groove 5. A clamping mechanism is arranged at the bottom end of the intake pipe 2; the clamping mechanism includes a spring 7. The spring 7 is fixedly installed at the top end of the inner side wall of the intake pipe 2. A limiting plate 8 is fixedly installed at the bottom end of the spring 7. The outer side wall of the limiting plate 8 is attached to the outer side wall of the filter screen plate 6. A limiting mechanism is arranged at the top end of the inner side wall of the intake pipe 2 and is attached to one end of the outer side wall of the filter screen plate 6; the limiting mechanism includes a fixing plate 10. The fixing plate 10 is fixedly installed at the inner top end of the intake pipe 2. The outer side wall of the fixing plate 10 is attached to the outer side wall of the filter screen plate 6. By installing the fixing plate 10, it is convenient to perform a limiting operation on the filter screen plate 6. Two sealing plates 11 are symmetrically and fixedly installed at the top end of the support 4. The outer side walls of the two sealing plates 11 are both attached to the outer side wall of the filter screen plate 6. By installing the sealing plates 11, it is convenient to perform a filling operation on the gap between the filter screen plate 6 and the intake pipe 2.

[0025] Please refer to Figures 1-4 , a limiting cylinder 9 is fixedly installed at the top end of the inner side wall of the intake pipe 2. The limiting cylinder 9 is slidably connected to the outer side wall of the limiting plate 8. The spring 7 is located inside the limiting cylinder 9. In this air filter protection structure, the air discharged through the exhaust pipe 3 is filtered by the intake pipe 2 and the filter screen plate 6. The bottom area of the filter screen plate 6 is supported by the fixing groove 5 on the support 4. The top end of the filter screen plate 6 contacts the limiting plate 8, thereby driving the spring 7 to be compressed, so that the filter screen plate 6 is fixed inside the intake pipe 2 under the cooperation of the limiting mechanism. Through the extension of the spring 7, the limiting plate 8 is driven to be attached to the outer side wall of the filter screen plate 6, thereby completing the fixation of the filter screen plate 6, improving the installation efficiency of the device for the filter screen plate 6, replacing the fixing method of using screws for the filter screen plate 6, and improving the practicability.

[0026] Please refer to Figure 1, it should also be noted that the bottom end of the intake pipe 2 is fixedly connected to the outer wall of the air filter 1 through the bracket 12. By installing the bracket 12, the intake pipe 2 can be supported.

[0027] Please refer to Figure 1 , a bottom plate 13 is fixedly installed at the bottom end of the air filter 1, and a plurality of support columns 14 are fixedly installed around the bottom end of the bottom plate 13. By installing the bottom plate 13 and the support columns 14, the device can be supported.

[0028] Please refer to Figure 1 , a plurality of handles 15 are symmetrically and fixedly installed on the outer wall of the air filter 1. By installing the handles 15, it is convenient for the user to move the device.

[0029] In summary, when the air filter protection structure is in use, the device is moved to the working area through the handle 15, and the device is supported by the bottom plate 13 and the support columns 14. The bottom area of the filter mesh plate 6 is slidably clamped with the fixing groove 5 opened on the support 4, and the top area of the filter mesh plate 6 contacts the limiting plate 8. Then, the filter mesh plate 6 moves longitudinally through the limiting plate 8, driving the spring 7 to be compressed. Thus, the filter mesh plate 6 is fixed inside the intake pipe 2 under the limitation of the fixing plate 10. When the spring 7 returns to its initial state, the limiting plate 8 is driven to return to its initial state under the limitation of the limiting cylinder 9, so that the limiting plate 8 fits with the filter mesh plate 6, completing the installation of the filter mesh plate 6. When the filter mesh plate 6 needs to be replaced, the above operation process can be reversed.
