Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a filter that is easy to clean. Background Technology

[0002] Filters are an indispensable device in pipelines transporting media, typically installed at the inlet of pressure reducing valves, pressure relief valves, level control valves, or other equipment. A pipeline filter consists of a filter cartridge, internal components, and a discharge port. When the fluid to be filtered enters the pipeline filter, impurities within the fluid are blocked by the filter screen on the internal components, and the filtered fluid is discharged from the pipeline filter.

[0003] For example, application number CN202421710541.9 relates to the field of filters and discloses a pipe filter that is easy to clean. The filter includes a filter tube with an inlet at its left end and an outlet at its right end.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a scraper, enables the scraper to scrape and clean the bottom of the filter plate during the cleaning process of the filter plate by the cleaning rack. This solves the problem that while the cleaning rod on the cleaning plate pushes out the impurities blocking the filter plate to prevent clogging, it cannot clean the impurities attached to the bottom of the filter plate, which leads to incomplete cleaning and the filter plate becoming clogged again in a short time. This invention has the advantage of being an auxiliary cleaning tool.

[0015] 2. This utility model, by setting a rotating component, causes the fixed rod to move downward through the frustum block, which in turn causes the spiral groove on the surface of the transmission rod to move against the positioning pin on the inner wall of the mounting cylinder. As the transmission rod continues to move downward, the positioning pin and the spiral groove cooperate to rotate the transmission rod. By setting a transmission component, the rotation of the transmission rod can drive the connecting rod to rotate. The rotation of the connecting rod can then drive the driving rod to rotate through the movable sleeve on the surface of the driving rod. This allows the driving rod to drive the scraper plate to rotate, thus enabling the scraper plate to scrape and clean the bottom of the filter plate. At the same time, the use of the movable sleeve and the driving rod ensures that the transmission rod itself can still move downward while the connecting rod drives the scraper plate to rotate.

[0016] 3. This utility model sets a limiting ring so that the movable ring can be limited by the limiting ring, thereby enabling the movable ring to stably support the scraping plate to rotate. Furthermore, by setting a positioning block, the use of the positioning block can limit the movable sleeve on the surface of the drive rod, preventing the movable sleeve from separating from the drive rod.

[0021] 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.

[0022] like Figures 1 to 3 As shown, this utility model provides an easy-to-clean filter, including a filter tube 1, an inlet pipe 2, and an outlet pipe 3. The inlet pipe 2 is fixedly connected to the left side of the filter tube 1, and the outlet pipe 3 is fixedly connected to the right side of the filter tube 1. A filter plate 4 is fixedly installed inside the filter tube 1. A fixing frame 5 is provided at the top of the filter tube 1. Springs 6 are fixedly connected to both sides of the bottom of the fixing frame 5. The bottom ends of the springs 6 are fixedly connected to the top of the filter tube 1. Limiting rods 7 are fixedly connected to both sides of the top of the filter tube 1. The top ends of the limiting rods 7 penetrate to the top of the fixing frame 5 and are movably connected to the fixing frame 5. A fixing rod 8 is fixedly connected to the bottom of the fixing frame 5. The bottom end of the fixing rod 8 penetrates to the interior of the filter tube 1 and is movably connected to the filter tube 1. A frustum block 9 is movably embedded in the bottom end of the fixing rod 8. A transmission rod 10 is fixedly connected to the bottom of the filter tube 1. The top end of the transmission rod 10 extends through to the top of the filter plate 4 and is movably connected to the filter plate 4. A movable ring 11 is movably connected inside the filter tube 1. A scraper 12 is fixedly connected to the inner wall of the movable ring 11. Several scraper 12s are arranged in a ring and are evenly distributed. The scraper 12 is movably connected to the bottom of the filter plate 4. A rotating assembly 13 is fixedly connected to the bottom of the inner wall of the filter tube 1. A cleaning frame 14 is fixedly connected to the surface of the fixed rod 8. The cleaning frame 14 is movably connected to the filter plate 4. A transmission assembly 15 is fixedly connected to the top of both sides of the transmission rod 10. The bottom end of the transmission rod 10 extends through to the bottom of the filter tube 1 and is movably connected to the filter tube 1. A drain outlet 16 is opened at the bottom of the filter tube 1. A sealing plate 17 is fixedly connected to the bottom end of the transmission rod 10.

[0023] refer to Figure 2The rotating assembly 13 includes a mounting cylinder 131, with positioning pins 132 fixedly connected to both sides of the inner wall of the mounting cylinder 131, and spiral grooves 133 fixedly connected to both sides of the surface of the transmission rod 10, with the positioning pins 132 movably connected to the spiral grooves 133.

[0024] As a technical optimization of this utility model, by setting a rotating component 13, when the fixed rod 8 drives the transmission rod 10 to move downward through the frustum block 9, it will drive the spiral groove 133 on the surface of the transmission rod 10 to move on the positioning pin 132 on the inner wall of the mounting cylinder 131. As the transmission rod 10 continues to move downward, the positioning pin and the spiral groove 133 will cooperate to make the transmission rod 10 rotate.

[0025] refer to Figure 3 The transmission assembly 15 includes a connecting rod 151, with a movable sleeve 152 fixedly connected to the outer end of the connecting rod 151. A drive rod 153 is movably connected inside the movable sleeve 152, and the top end of the drive rod 153 is fixedly connected to the bottom of the scraping plate 12.

[0026] As a technical optimization of this utility model, by setting a transmission component 15, the transmission rod 10 can rotate to drive the connecting rod 151 to rotate. After the connecting rod 151 rotates, it can drive the driving rod 153 to rotate through the movable sleeve 152 on the surface of the driving rod 153. The driving rod 153 can drive the scraping plate 12 to rotate, so that the scraping plate 12 can scrape and clean the bottom of the filter plate 4. At the same time, the use of the movable sleeve 152 and the driving rod 153 can ensure that the transmission rod 10 itself can still move downward while the connecting rod 151 drives the scraping plate 12 to rotate.

[0027] refer to Figure 3 A limiting ring 18 is movably embedded in the inner wall of the filter tube 1, and the inner wall of the limiting ring 18 is fixedly connected to the surface of the movable ring 11.

[0028] As a technical optimization of this utility model, by setting a limiting ring 18, the movable ring 11 can be limited by the limiting ring 18, thereby enabling the movable ring 11 to stably support the scraping plate 12 to rotate.

[0029] refer to Figure 2 The bottom end of the drive rod 153 is fixedly connected to a positioning block 19, which is movably connected to the movable sleeve 152.

[0030] As a technical optimization of this utility model, by setting a positioning block 19, the use of the positioning block 19 can limit the movable sleeve 152 on the surface of the drive rod 153, so as to prevent the movable sleeve 152 from separating from the drive rod 153.

[0031] refer to Figure 3A limiting groove 20 is provided on the front side of the surface of the fixed rod 8. A limiting plate 21 is movably connected to the front side of the top of the filter tube 1. The limiting plate 21 is movably connected to the limiting groove 20. A movable pin 22 is movably embedded on the front side of the top of the filter tube 1. The movable pin 22 is fixedly connected to the bottom of the limiting plate 21.

[0032] As a technical optimization of this utility model, by setting a limiting groove 20, a limiting plate 21 and a movable pin 22, the limiting plate 21 can limit the fixed rod 8 after being inserted into the limiting groove 20, and the movable pin 22 can limit the limiting plate 21, thereby preventing the limiting plate 21 from separating from the filter tube 1.

[0033] refer to Figure 3 A gripping rod 23 is fixedly connected to the front side of the top of the limiting plate 21.

[0034] As a technical optimization of this utility model, by setting a grip lever 23, the user can easily grip the limiting plate 21, thereby facilitating the user to push the grip lever 23 to move it back and forth.

[0035] The working principle and usage process of this utility model are as follows: When in use, pushing the fixed frame 5 downwards compresses the spring 6, simultaneously moving the fixed rod 8 downwards. After the fixed rod 8 moves downwards, it drives the transmission rod 10 downwards via the frustum block 9, which in turn moves the cleaning frame 14 downwards. As the transmission rod 10 moves downwards, the engagement between the positioning pin 132 inside the mounting cylinder 131 and the spiral groove 133 on the surface of the transmission rod 10 causes the transmission rod 10 to rotate. This downward rotation of the transmission rod 10 simultaneously drives the connecting rod 151 to rotate and move. 151 can drive the movable sleeve 152 to rotate, which in turn drives the drive rod 153 to rotate. This, in turn, drives the scraper 12 inside the movable ring 11 to rotate. As the cleaning frame 14 inserts into the filter plate 4 to clean it, the scraper 12 rotates and scrapes the bottom of the filter plate 4. At this time, the transmission rod 10 will drive the sealing plate 17 to move downward, so that the sealing plate 17 releases the seal on the drain outlet 16, allowing the impurities cleaned on the filter plate 4 to be discharged through the drain outlet 16, thereby achieving the effect of auxiliary cleaning.

[0036] In summary, this easy-to-clean filter, by setting up a scraper 12, can scrape and clean the bottom of the filter plate 4 during the cleaning process of the cleaning frame 14. This solves the problem that while the cleaning rod on the cleaning plate can push out the impurities clogging inside the filter plate to prevent clogging, it cannot clean the impurities attached to the bottom of the filter plate. This would result in incomplete cleaning of the filter plate, causing it to become clogged again in a short time, thus presenting certain limitations.
