DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0023] As Figures 1 to 4 shown, a rotary scraping structure for cleaning filter screen, including filter 1, filter screen assembly 2 and rotary scraping assembly 3. The top of filter 1 is provided with water inlet 15 and water outlet 16, and the bottom of filter 1 is provided with sewage outlet 17. Filter screen assembly 2 is cylindrical, and is installed in the middle of filter 1, and the top of filter screen assembly 2 is communicated with water inlet 15, and the bottom of filter screen assembly 2 is communicated with sewage outlet 17. Water enters from water inlet 15 at the top of filter 1 and is filtered through filter screen assembly 2. Filter screen assembly 2 is cylindrical, and its fine mesh structure can trap impurities in water, and clean water continues to flow to water outlet 16 and is discharged from filter 1.
[0024] Rotary scraping assembly 3 includes rotary support 4, fixed sleeve 5 and movable scraper 6, the top of rotary support 4 is rotatably connected with filter 1, and the bottom of rotary support 4 extends to the inner side of filter screen assembly 2, fixed sleeve 5 is fixedly connected with rotary support 4, movable sliding groove 7 is formed in the side of fixed sleeve 5, movable sliding rod 8 is slidably connected with movable sliding groove 7 on one side of movable scraper 6, and the other side of movable scraper 6 abuts against filter screen assembly 2.
[0025] Under the action of the filter screen assembly 2, impurities in the water (such as particulate matter, suspended matter, etc.) are effectively intercepted inside the filter screen assembly 2. As the use time increases, impurities on the filter screen assembly 2 will gradually accumulate. When the filter screen assembly 2 needs to be cleaned, the rotating support 4 is driven to rotate, such as an external power source (motor), which is fixedly arranged at the top of the filter 1, and the output end of the motor is coaxially fixedly connected with the rotating support 4 through the filter 1. The top of the rotating support 4 is rotatably connected with the filter 1 to ensure smooth rotation. The bottom of the rotating support 4 extends to the inside of the filter screen assembly 2 and drives the fixed sleeve 5 and the movable scraper 6 to rotate together.
[0026] One side of the movable scraper 6 is slidably connected with the movable sliding groove 7 of the fixed sleeve 5 through the movable sliding rod 8, ensuring that the scraper can move closely to the inner wall of the filter screen assembly 2. With the rotation of the rotating support 4, the movable scraper 6 will scrape off the impurities attached to the filter screen assembly 2. The scraped impurities are brought to the vicinity of the bottom of the filter screen assembly 2 or the blowdown port 17 with the rotation of the rotating support 4. Since the bottom of the filter screen assembly 2 is in communication with the blowdown port 17, the impurities are finally discharged from the filter 1 through the blowdown port 17.
[0027] By adjusting the position of the movable sliding rod 8 in the movable sliding groove 7, the distance between the movable scraper 6 and the rotating support 4 can be adjusted. This structure makes the rotating and scraping assembly 3 adaptable to filter screen assemblies 2 of different diameters, improving the versatility and flexibility of the rotating and scraping assembly 3.
[0028] The rotating and scraping structure realizes the cleaning of the filter screen assembly 2 by rotating the rotating support 4 and scraping off the impurities attached to the filter screen assembly 2, reduces the frequency and difficulty of manual intervention, and improves the cleaning efficiency. Regular cleaning of the filter screen assembly 2 can effectively prevent blockage and wear caused by impurity accumulation, thereby prolonging the service life of the filter screen assembly 2 and reducing replacement costs. The cleaned filter screen assembly 2 can maintain a high filtration efficiency, ensuring water quality safety, while reducing system pressure loss caused by filter screen assembly 2 blockage. By adjusting the distance between the movable scraper 6 and the rotating support 4, the rotating and scraping assembly 3 can adapt to filter screen assemblies 2 of different diameters, improving the versatility and flexibility of the rotating and scraping assembly 3.
[0029] Reference Figure 2 and Figure 3As shown, in some embodiments, the rotating support 4 comprises a rotating plate 9, a connecting rod 10 and a rotating shaft 11, and the inner side of the filter 1 is provided with a rotating groove 12, the rotating plate 9 is rotationally connected with the rotating groove 12 to ensure the stability of rotation. One end of the connecting rod 10 is fixedly connected with the rotating plate 9, and the other end of the connecting rod 10 is fixedly connected with the rotating shaft 11. When the rotating plate 9 rotates in the rotating groove 12, the rotating shaft 11 rotates with the rotating plate 9 through the connecting rod 10. The rotating plate 9 has a circular ring structure, and the axis of the rotating shaft 11 coincides with the axis of the rotating plate 9. The cross section of the connecting rod 10 has a cylindrical structure, which ensures the strength during torque transmission, so that the rotating power of the rotating plate 9 can be stably transmitted to the rotating shaft 11. At the same time, the arc surface of the cylindrical connecting rod 10 can guide the water flow to a certain extent. The water flow flows along the arc surface of the connecting rod 10, reducing the direct impact on the entire rotating structure.
[0030] Reference Figure 2 As shown, in some embodiments, the rotating scraping assembly 3 further comprises driving blades 13, which are arranged in a matrix on the top of the rotating support 4 and are integrally formed with the rotating support 4. When the water flow passes through, the impact force of the water flow acts on the driving blades 13. Since the driving blades 13 are arranged in a matrix, they can receive the water flow impact force omnidirectionally and uniformly, so that the rotating support 4 is more balanced in force. The driving blades 13 drive the rotating plate 9 to rotate after being subjected to force. The rotating plate 9 has a circular ring structure and is rotationally connected with the rotating groove 12 provided in the inner side of the filter 1 to ensure the stability of rotation.
[0031] Reference Figure 4 As shown, in some embodiments, the rotating scraping assembly 3 further comprises a spring 14, one end of which is connected with the movable sliding groove 7, and the other end of which is connected with the movable sliding rod 8. During the rotation of the rotating support 4, the spring 14 is always in a stressed state. When the movable scraping plate 6 contacts the impurities protruding on the filter screen assembly 2 or the filter screen assembly 2 is slightly deformed due to water pressure, the movable sliding rod 8 will produce a certain displacement in the movable sliding groove 7, and at this time the spring 14 will be elastically deformed. The elastic restoring force of the spring 14 can ensure that the movable scraping plate 6 is always tightly attached to the inner wall of the filter screen assembly 2, and can effectively remove impurities whether the surface of the filter screen assembly 2 is flat or not. Even if the filter screen assembly 2 is slightly deformed after being used for a period of time, the spring 14 can maintain effective contact between the movable scraping plate 6 and the filter screen assembly 2 through its own adjustment, ensuring the stable performance of the cleaning work.
[0032] Reference Figure 3As shown, in some specific embodiments, the movable scraper 6 is provided with a plurality of movable sliding grooves 7 arranged in a ring array on the side of the fixed sleeve 5, and a movable sliding rod 8 is arranged on the side of each movable scraper 6 and connected with the corresponding movable sliding groove 7 in a sliding fit. During rotation, the movable scrapers 6 move synchronously along the movable sliding grooves 7 arranged in a ring array, and the impurities on the filter screen are scraped off from different directions, so that the occurrence of cleaning dead angles is avoided, and the effective cleaning of each part of the filter screen is ensured.
[0033] In some specific embodiments, the movable scraper 6 is made of silica gel, which has good flexibility and wear resistance. During the process of contacting the filter screen to scrape off the impurities, the flexibility of the silica gel can make the movable scraper 6 better fit the curved surface of the filter screen, so that the movable scraper 6 can be in close contact with the filter screen even if the filter screen has slight unevenness, and the impurities can be effectively removed. At the same time, the good wear resistance ensures that the movable scraper 6 is not easily damaged during long-term use, prolongs the service life of the scraper, and further ensures the continuous and stable performance of the cleaning work.
[0034] Reference Figure 4 As shown, in some specific embodiments, the movable scraper 6 is integrally formed with the movable sliding rod 8, which eliminates the connection gap that may exist between the movable scraper 6 and the movable sliding rod 8, so that the movable scraper 6 can move more accurately along the movable sliding groove 7 when the fixed sleeve 5 rotates, ensuring the stability and reliability of the movement. The integrally formed structure also enhances the overall strength of the movable scraper 6 and the movable sliding rod 8, so that the movable scraper 6 and the movable sliding rod 8 are not easily broken or damaged when dealing with complex impurity scraping work, further improving the stability of the cleaning work.
[0035] In order to facilitate the understanding of the working principle of the embodiments of the present scheme by the personnel in the field, the working principle of the embodiments of the present scheme will be described in combination with specific application scenarios:
[0036] Water enters from the water inlet 15 at the top of the filter 1, passes through the filter screen assembly 2 for filtration. The filter screen assembly 2 is in a cylindrical shape, and its fine mesh structure can trap impurities in the water, while the clean water continues to flow to the water outlet 16 and is discharged from the filter 1. As the use time increases, the impurities on the filter screen assembly 2 will gradually accumulate.
[0037] By rotating the rotating support 4 through the motor or the driving blade 13, the movable scraper 6 can scrape off the impurities attached to the filter screen assembly 2 and carry them to the bottom of the filter screen assembly 2 or near the sewage outlet 17. Since the bottom of the filter screen assembly 2 is connected with the sewage outlet 17, the impurities are finally discharged from the filter 1 through the sewage outlet 17, realizing the cleaning of the filter screen assembly 2. By adjusting the position of the movable sliding rod 8 in the movable sliding groove 7, the distance between the movable scraper 6 and the rotating support 4 can be adjusted to adapt to filter screen assemblies 2 of different diameters.
[0038] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
