Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically a cleaning device for stainless steel filters. Background Technology

[0002] Stainless steel filters, as a high-efficiency and durable separation device, are widely used in many industrial fields such as chemical, pharmaceutical, food and beverage, water treatment, and petrochemical industries due to their excellent corrosion resistance, high strength and good filtration accuracy. They are mainly used to intercept solid particles, impurities and other pollutants in fluids to ensure the stability of subsequent production processes and product quality.

[0003] As the core functional component of a stainless steel filter, the filter element's filtration performance directly determines the operating efficiency of the entire filtration system. During long-term use, a large amount of trapped impurities, dirt, colloids, and other pollutants will gradually accumulate on the surface and internal pores of the filter element, leading to increased filtration resistance, decreased flow rate, and even secondary pollution of the filter media. Therefore, it is necessary to clean and maintain the filter element regularly to restore its filtration performance.

[0004] Currently, the main methods for cleaning stainless steel filter elements are as follows: First, manual disassembly and cleaning, which involves manually disassembling the filter and removing the filter element, then wiping it with a brush, rinsing it with a high-pressure water gun, or soaking it in a chemical cleaning agent; second, online cleaning devices, which use fixed spray pipes inside the filter to rinse the surface of the filter element with high-pressure water.

[0005] The existing technology has the following shortcomings:

[0006] Manual disassembly and cleaning is not only labor-intensive and inefficient, but frequent disassembly and assembly can also lead to a decline in the filter's sealing performance. In addition, manual wiping is difficult to penetrate the internal pores of the filter element, resulting in incomplete cleaning. Online fixed spray pipe cleaning cannot fully rinse the filter element due to the fixed spray angle. Especially for filter elements with complex structures, it is difficult to effectively remove contaminants from the inside and dead corners. Utility Model Content

[0007] To overcome the above-mentioned defects, this utility model provides a stainless steel filter cleaning device, which solves the problems of manual disassembly and cleaning in the prior art, which is not only labor-intensive and inefficient, but also prone to causing a decline in the sealing performance of the filter due to frequent disassembly and assembly. At the same time, manual wiping is difficult to penetrate into the internal pores of the filter element, resulting in incomplete cleaning. Online fixed spray pipe cleaning cannot fully rinse the filter element due to the fixed spray angle, especially for filter elements with complex structures, where it is difficult to effectively remove contaminants on the inside and in dead corners.

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figures 1-6As shown, this utility model provides a technical solution:

[0027] A stainless steel filter cleaning device includes a filter body 1, with a top cover 2 and a bottom cover 3 at both ends of the filter body 1. A filter element 4 is installed inside the filter body 1. A second fixing block 10 is provided at the bottom of the bottom cover 3. A limiting rod 15 is fixedly connected to the top of the second fixing block 10. Fixing rods are provided on both sides of the second fixing block 10 in a symmetrical structure, and a first scraper 13 and a second scraper 14 are respectively connected to the top of the fixing rods. A cleaning mechanism is provided inside the limiting rod 15.

[0028] The cleaning mechanism includes a water inlet pipe 9, a connecting block 18 connected to the top of the water inlet pipe 9, a drain block 19 connected to the outside of the connecting block 18, a connecting pipe 20 connected to the end of the drain block 19, and the drain blocks 19 are connected in series through the connecting pipe 20. The connecting block 18 and the drain block 19 are slidably connected to the limiting rod 15. The cleaning mechanism is located inside the filter element 4, and a drive mechanism that moves up and down in coordination with the cleaning mechanism is provided at the bottom of the bottom cover 3.

[0029] Specifically, during routine cleaning of filter element 4, cleaning water is introduced through water inlet pipe 9. The water flows through the passage formed by connecting block 18, drain block 19 and connecting pipe 20 and then sprays out. At the same time, the driving mechanism drives the cleaning mechanism to move up and down along the limit rod 15. With the help of the annular structure of drain block 19, the inner side of filter element 4 can be thoroughly and evenly rinsed.

[0030] During the cleaning process, gas is introduced through the air inlet pipe 11 to raise the filter element 4 and separate its bottom from the second fixed block 10. This avoids the impurities accumulated at the bottom from affecting the cleaning effect and facilitates the smooth discharge of sewage from the filter body 1. When deep cleaning is required, after the cleaning mechanism completes the internal rinsing, the first fixed block 6 and the drive mechanism are removed first, and then the bottom cover 3 is opened. By manually rotating the second fixed block 10, the first scraper 13 and the second scraper 14 on both sides of it are driven to scrape the inner wall of the filter body 1 and the outer wall of the filter element 4 respectively, thoroughly removing the attached stubborn impurities.

[0031] Regular cleaning achieves efficient cleaning through mechanized up-and-down movement flushing and air lifting drainage, eliminating the need for frequent disassembly of parts and saving operation time. The scraper structure during deep cleaning can specifically handle stubborn stains. Combined with the removable bottom cover 3 design, it balances the convenience of daily maintenance with the thoroughness of deep cleaning. At the same time, the setting of the limit rod 15 and the fixing block ensures the stability of the cleaning mechanism and scraper during operation, which improves the overall cleaning efficiency and service life of the filter.

[0032] The drive mechanism includes a first fixed block 6, which is bolted to the bottom of the bottom cover 3. A symmetrical arrangement of electric push rods 7 is arranged inside the bottom cover 3. A movable plate 8 is fixedly installed at the output end of the electric push rod 7, and the movable plate 8 is fixed to the outside of the water inlet pipe 9. The water inlet pipe 9 passes through the first fixed block 6, and a retractable water hose is connected to the end of the water inlet pipe 9. Multiple sets of telescopic rods 16 are embedded in the second fixed block 10. The telescopic rods 16 have a piston cylinder structure, and a support block 17 is connected to the output end of the telescopic rod 16. The support block 17 is located on the filter element. 4. At the bottom, the telescopic rod 16 is connected to an air supply pipe. The second fixing block 10 is provided with an air inlet pipe 11 for use with the air supply pipe. The end of the air inlet pipe 11 is threaded with a sealing cap. The air inlet pipe 11 passes through the bottom cover 3. The lower part of the inner wall of the filter body 1 is snapped with a limit ring 12. The end of the fixing rod is located at the top of the limit ring 12 and is slidably connected to it. The first scraper 13 is in contact with the inner wall of the filter body 1. The second scraper 14 is in contact with the outer wall of the filter element 4. The outer side of the filter body 1 is provided with a ring-shaped support leg 5.

[0033] Specifically, during the cleaning operation, the first fixing block 6 is securely installed on the bottom of the bottom cover 3 with bolts, providing support for the overall drive mechanism. The electric push rods 7 symmetrically arranged inside the bottom cover 3 are activated, and their output ends drive the movable plate 8 fixed on the outside of the water inlet pipe 9 to move up and down, thereby causing the water inlet pipe 9 to move synchronously along the passage of the first fixing block 6. In conjunction with the retractable water supply hose connected to the end of the water inlet pipe 9, the cleaning mechanism can be stably raised and lowered on the limit rod 15, ensuring a thorough rinsing of the inside of the filter element 4.

[0034] When it is necessary to raise the filter element 4, open the sealing cap at the end of the air inlet pipe 11 and supply air to the air supply pipe in the second fixed block 10 through the air inlet pipe 11. After the gas enters the telescopic rod 16 of the piston cylinder structure, it pushes the support block 17 at its output end to rise, so that the support block 17 lifts the bottom of the filter element 4, realizing the separation of the filter element 4 from the second fixed block 10, which facilitates the discharge of sewage. After the operation is completed, close the sealing cap to block the gas from entering.

[0035] When deep cleaning is required, since the end of the fixing rod is located at the top of the limiting ring 12 which is snapped and connected to the inner wall of the filter body 1 and can slide, when the second fixing block 10 is rotated, the first scraper 13 can fit against the inner wall of the filter body 1 and the second scraper 14 can fit against the outer wall of the filter element 4 and move stably to scrape away impurities.

[0036] The symmetrical arrangement of the electric push rod 7 and the movable plate 8 ensures the smoothness of the lifting and lowering of the water inlet pipe 9. The telescopic water supply hose ensures the continuity of water supply and does not affect movement. The telescopic rod 16 with the piston cylinder structure, together with the air inlet pipe 11, enables the convenient lifting of the filter element 4. The operation is simple and the sealing is controllable. The limiting ring 12 enhances the stability of the scraper when it is scraping, and avoids deviation that affects the cleaning effect. The bolt connection of the first fixing block 6 is easy to disassemble and assemble. The ring structure of the support leg 5 improves the overall stability of the filter and the cleaning effect.

[0037] The working principle of this utility model is as follows:

[0038] First, the built-in cleaning mechanism works in conjunction with the drive mechanism to achieve efficient cleaning of the filter element 4. During regular cleaning, the electric push rod 7 in the drive mechanism drives the movable plate 8 and the water inlet pipe 9 to move up and down, causing the cleaning mechanism to rise and fall along the limit rod 15. At the same time, the cleaning water introduced by the water inlet pipe 9 is sprayed out through the passage composed of the connecting block 18, the drain block 19 and the connecting pipe 20. The structure of the annular drain block 19 is used to thoroughly flush the inside of the filter element 4.

[0039] Secondly, during the cleaning process, air can be supplied to the telescopic rod 16 inside the second fixed block 10 through the air inlet pipe 11. With the help of the telescopic rod 16 of the piston cylinder structure, the support block 17 is pushed up, raising the filter element 4 to separate it from the second fixed block 10. This not only avoids the accumulation of impurities affecting the cleaning effect, but also facilitates the smooth discharge of sewage.

[0040] It is worth mentioning that when deep cleaning is required, the first fixing block 6 and the drive mechanism can be removed and the bottom cover 3 can be opened. By manually rotating the second fixing block 10, the first scraper 13 and the second scraper 14 connected by the fixing rods on both sides can be used to scrape the filter body 1 inner wall and the filter element 4 outer wall respectively. The limiting ring 12 ensures the stability of the scraping process by limiting the fixing rods.

[0041] Finally, the bolted connection of the first fixing block 6 facilitates disassembly and assembly, the retractable water supply hose ensures that the water supply is not affected by lifting and lowering, and the ring design of the support leg 5 enhances the stability of the equipment placement. By combining mechanized cleaning with manual deep cleaning, a balance between efficient cleaning and convenient maintenance is achieved.

[0042] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
