[0002] A pipe filter is a device used to process substances flowing through a pipe. They are usually used in industrial production and processing processes to remove impurities, separate solids and liquids, and adjust flow rates. Pipe filters can use different filter materials and structures according to different needs and process requirements, such as filter screens, filter elements, filter membranes, etc. During the liquid filtration process, the filter screen inside the filter needs to be cleaned in time to ensure the normal flow rate of the liquid. However, the commonly used cleaning method is to disassemble the filter, take out the internal filter screen for cleaning, then reset the filter screen and install it, and close the filter as a whole again. The whole process has a slow cleaning efficiency for the filter and cannot meet the cleaning requirements. Therefore, the inventor proposed a pipe filter. Summary of the invention

[0025] Reference Figure 1 A pipeline filter comprises a filter body 1, and also comprises connecting pipes 3 arranged on both sides of the filter body 1, a handle 2 is fixed on the outer wall of the filter body 1, and a bottom plate 6 is hinged at the bottom of the filter body 1;

[0026] Reference Figure 2Two groups of fixed outer tubes 4 are fixed on the upper surface of the filter body 1. An operating rod 5 is vertically inserted into the fixed outer tube 4. The operating rod 5 is in a U-shaped structure and both ends pass through the fixed outer tube 4 and extend into the filter body 1. A driving rod 14 is provided inside the filter body 1. A stopper 17 is provided on the top of the driving rod 14. The driving rod 14 is vertically arranged and fixedly connected to the operating rod 5. One end of the operating rod 5 extending into the filter body 1 is fixedly connected to a scraper 12; an inner tube 13 is fixedly installed inside the filter body 1. The inner tube 13 corresponds to the connecting tube 3. A filter screen 11 is provided inside the inner tube 13. The filter screen 11 is vertically arranged. The end of the driving rod 14 away from the operating rod 5 is fixedly connected to a scraper 12. The scraper 12 fits the surface of the filter screen 11. The scraper 12 penetrates along the top of the inner tube 13, and the end of the scraper 12 penetrating into the inner tube 13 is inclined. A connecting block 9 is fixedly connected to the side wall of the baffle 7, and the connecting block 9 extends into the filter body 1. A fixing block 10 is fixedly connected to the outer wall of the filter body 1. An adjusting screw 8 is inserted into the internal thread of the fixing block 10, and the adjusting screw 8 is threadedly installed with the connecting block 9.

[0027] Reference Figure 3 A bottom block 16 is fixedly connected to the inner wall of the fixed outer tube 4 , and a lifting block 15 is fixedly connected to the outer wall of one end of the operating rod 5 that penetrates into the fixed outer tube 4 , and the lifting block 15 corresponds to the bottom block 16 .

[0028] A spring 18 is provided between the bottom block 16 and the lifting block 15 , and the spring 18 is arranged vertically.

[0029] Reference Figure 4 The bottom end surface of the inner tube 13 has an opening, and a sealing head 20 is inserted into the opening. The sealing head 20 corresponds to the position of the scraper 12. A baffle 7 is fixedly connected below the sealing head 20. The baffle 7 is arranged below the inner tube 13. A closed ring 21 is provided at one end of the baffle 7 close to the inner tube 13. The closed ring 21 fits the outer wall of the inner tube 13.

[0030] When in use, the filter body 1 is moved to the pipeline delivery position by the handle 2, and then the filter body 1 is installed on the pipeline. When the liquid is delivered, the filter screen 11 inside the filter body 1 isolates the impurities in the liquid to ensure the cleanliness of the liquid delivery. After a period of delivery, the liquid delivery can be stopped, and the filter screen 11 can be quickly cleaned. The operating rod 5 is pressed down and penetrated into the fixed outer tube 4, and the driving rod 14 is driven to move downward, and then the scraper 12 is pressed to move along the surface of the filter screen 11 to clean the surface of the filter screen 11. The impurities adhered to the filter screen 11 are scraped off to the bottom of the inner tube 13. At this time, the adjusting screw 8 is turned, and the adjusting screw 8 and the connecting block 9 are threadedly driven. The connecting block 9 is forced to drop, driving the baffle 7 to move downward, and the sealing head 20 on the baffle 7 is removed from the inner tube 13. Then the impurities can fall into the filter body 1. At this time, the bottom plate 6 can be opened to clean the impurities, and then the operating rod 5 is released. When the operating rod 5 is lowered, the lifting block 15 of the outer wall moves toward the bottom block 16 to compress the spring 18. When released, the spring 18 resets, the operating rod 5 moves up, driving the driving plate to move up, and then the scraper 12 moves up in contact with the filter screen 11 and returns to its original position. The scraper 12 will not completely withdraw from the inner tube 13. When the driving rod 14 moves up, it is blocked by the limit block 17 at the top. The surface of the scraper 12 facing the filter screen 11 is an oblique setting, which guides the water flow. When the impurities are discharged, the adjusting screw 8 can be rotated in the opposite direction, and the connecting block 9 moves up, driving the baffle 7 to block the inner wall of the inner tube 13, and the sealing head 20 enters the bottom of the inner tube 13 again to block the inner tube 13 to prevent the liquid from flowing out.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
