[0002] A pipeline filter refers to a device for filtering impurities inside a pipeline in a hydraulic system, and is commonly used in the fields of metallurgy, chemical industry, petroleum, and urban water supply.

[0003] However, corresponding filter screens are provided inside existing pipeline filters. The filter screens are clogged due to the accumulation of impurities during long-term use and need to be disassembled and cleaned regularly. Since the filter screens are usually arranged on the inner wall, the side plates of the filter need to be opened during disassembly, and then the filter screens are taken out for cleaning. However, the side plates are fixed by a screw structure, and the disassembly and installation are relatively cumbersome and complex. Content of the Utility Model

[0013] Preferably, the outer wall of the scraping ring is closely attached to the inner wall of the filter body, and the hole of the filter body close to the handle is the water inlet hole.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] (1) Through the arrangement of the filtering component of the new pipeline filter, the fixing frame is inserted into the filter body, and the filter screen can block impurities. When too many impurities accumulate, the limiting plate can be rotated upward so that the limiting plate no longer presses against the fixing frame. Hold the handle and pull out the fixing frame from the filter body, then the filter screen can be cleaned. After cleaning, the fixing frame can be reinserted into the filter body, and the limiting plate is released. Under the elastic force of the torsion spring, the limiting plate rotates downward and presses against the outer wall of the fixing frame to limit the fixing frame. The operation is simple and fast, without the need to use screws for installation, improving the efficiency of disassembly and installation.

[0016] (2) Through the arrangement of the cleaning component of the new pipeline filter, after the filter body is used for a long time, some impurities will also accumulate on the inner wall of the filter body. Before pulling out the fixing frame for cleaning, the handle can be rotated. The handle drives the lead screw to rotate, the lead screw drives the nut pair to move downward, the nut pair drives the support frame and the scraping ring to move downward, and the scraping ring can scrape off the impurities on the inner wall of the filter body and make them fall on the filter screen. When the fixing frame is pulled out later, these impurities can be cleaned together, improving the cleanliness inside the filter body. BRIEF DESCRIPTION OF THE DRAWINGS

The filter body 01, torsion spring 26, sealing bearing 33 and nut pair 34 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all prior arts well-known to those skilled in the art, so they will not be elaborated here.

[0025] Including: a filter body 01, a filtering component 02 is arranged inside the middle of the filter body 01, and a cleaning component 03 is arranged inside the upper part of the filter body 01;

[0026] The filtering component 02 includes a fixing frame 21, a filter screen 22 is fixedly installed inside the fixing frame 21, a handle 23 is fixedly arranged at the outer end of the fixing frame 21, a limiting plate 24 abuts against the outer wall of the fixing frame 21, the limiting plate 24 can abut against the fixing frame 21 to limit the fixing frame 21, a fixing rod 25 penetrates through the upper part of the limiting plate 24, a torsion spring 26 is arranged on the outer wall of the fixing rod 25, the torsion spring 26 provides elastic force, and under the action of the elastic force of the torsion spring 26, the limiting plate 24 rotates downward and abuts against the outer wall of the fixing frame 21 to limit the fixing frame 21.

[0027] Further, the cleaning component 03 includes a handle 31. Rotating the handle 31 can drive the lead screw 32 to rotate. The lead screw 32 is connected to the handle 31 under the middle and lower part of the handle 31. The lead screw 32 is connected to the filter body 01 through a sealing bearing 33. The sealing bearing 33 plays a sealing role. A nut pair 34 is connected to the outer wall of the lead screw 32. A support frame 35 is fixedly installed on the outer wall of the nut pair 34. A scraping ring 36 is fixedly arranged on the outer wall of the support frame 35. When the scraping ring 36 moves downward, it can scrape off the impurities on the inner wall of the filter body 01. A guiding block 37 is fixedly arranged at one end of the scraping ring 36. The guiding block 37 plays a guiding role to ensure that the scraping ring 36 can move up and down.

[0028] Furthermore, the fixing frame 21 is slidably connected to the filter body 01, and the limiting plate 24 is rotatably connected to the fixing rod 25. When the limiting plate 24 rotates upward, the fixing frame 21 can be pulled out from the filter body 01.

[0029] Furthermore, the limiting plate 24 is closely attached to the outer wall of the fixing frame 21 to ensure that the limiting plate 24 can resist the fixing frame 21 and limit the fixing frame 21. The fixing rod 25 is fixedly connected to the filter body 01 to ensure the firmness of the position of the fixing rod 25.

[0030] Furthermore, both ends of the torsion spring 26 are fixedly connected to the limiting plate 24 and the filter body 01 respectively. The torsion spring 26 provides elastic force. Under the action of the elastic force of the torsion spring 26, the limiting plate 24 rotates downward and abuts against the outer wall of the fixing frame 21 to limit the fixing frame 21. The handle 31 is rotatably connected to the filter body 01 to ensure that the filter body 01 does not affect the rotation of the handle 31. When the handle 31 rotates, the lead screw 32 can be driven to rotate.

[0031] Furthermore, the lead screw 32 is rotatably connected to the filter body 01 through a sealing bearing 33. The sealing bearing 33 plays a sealing role. The filter body 01 is provided with a sliding groove corresponding to the guide block 37. The guide block 37 plays a guiding role to ensure that the scraping ring 36 can move up and down.

[0032] Furthermore, the outer wall of the scraping ring 36 is closely attached to the inner wall of the filter body 01. When the scraping ring 36 moves downward, the impurities on the inner wall of the filter body 01 can be scraped off. The hole of the filter body 01 close to the handle 31 is a water inlet hole to ensure that the impurities in the water can fall on the filter screen 22, facilitating the centralized treatment of the impurities.

[0033] Working principle: When in use, first rotate the handle 31. The handle 31 drives the lead screw 32 to rotate. The lead screw 32 drives the nut pair 34 to move downward. The nut pair 34 drives the support frame 35 and the scraping ring 36 to move downward. The scraping ring 36 can scrape off the impurities on the inner wall of the filter body 01 and make them fall on the filter screen 22. Rotate the limiting plate 24 upward so that the limiting plate 24 no longer abuts against the fixing frame 21. Hold the grip 23 and pull out the fixing frame 21 from the filter body 01, and then the filter screen 22 can be cleaned. The above is all the working principle of the present utility model.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
