Description

Technical Field

[0001] The utility model relates to the technical field of backwashing, in particular to a high-precision cyclone backwashing filter. Background Art

[0002] The high-precision cyclone backwashing filter is an efficient filtering device, which is realized by using cyclone and backwashing technologies. It generates a cyclone through a cyclone separator, causing solid particles to deposit in the central area. Then, the clean fluid passes through the filter for further filtration, providing a high-precision filtering effect. The equipped backwashing function can regularly clean the filter, prevent blockage, and extend the service life of the filter. This filter has the advantages of high-efficiency filtration, long service life, convenient maintenance, energy conservation and environmental protection, and is suitable for various industrial and commercial application scenarios.

[0003] After retrieval, a cyclone backwashing mechanism is disclosed in the publication number: CN205699640U, which is installed inside a filter tank. It includes a water outlet pipe arranged at the bottom of the filter tank. A plurality of arc-shaped cyclone elbows are installed on the inner section of the water outlet pipe located inside the filter tank. The cyclone elbows are arranged in a spiral shape and are all connected to the water outlet pipe. The bottom of the filter tank is funnel-shaped, and the water outlet pipe is located at the center of the bottom of the filter tank. The cyclone backwashing mechanism backwashes the filter media through the water flow forming a cyclone, enabling strong water flow in both the middle and around of the tank, and completely washing the filter media in the tank. The mechanism is located at the center of the bottom of the tank, making the formed cyclone distribution uniform, further ensuring uniform water flow intensity and improving the washing effect. In the existing filtration equipment of this application during backwashing, a fixed backwashing method is adopted, resulting in insufficient collision and friction between the filter media, poor backwashing effect, and large consumption of backwashing water and gas.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a swirl backwashing high-precision filter, which includes a tank body 1, a top cover 2 is fixedly connected to the upper surface of the tank body 1, a feed pipe 3 is fixedly connected to one side inside the tank body 1, a discharge pipe 4 is fixedly connected to the other side inside the tank body 1, fixed plates 5 are fixedly connected to the inner wall of the tank body 1 in an up-and-down symmetrical manner, a filter barrel 6 is fixedly connected between the two fixed plates 5, a pressure gauge 7 is disposed through the inside of the tank body 1, a sewage discharge pipe 8 is disposed through the lower side inside the tank body 1, a sewage pump 9 is fixedly connected to the outer wall of the sewage discharge pipe 8, a filter assembly 10 is disposed at one end of the sewage discharge pipe 8, a transmission pipe 12 is fixedly connected to one side of the filter assembly 10, a switch valve 13 is fixedly connected to the outer wall of the transmission pipe 12, and a controller 11 is fixedly connected to one side of the outer wall of the tank body 1; the filter assembly 10 includes a filter box 1001, the upper surface of the filter box 1001 is fixedly connected to one end of the sewage discharge pipe 8, a filter box 1002 is slidably connected inside the filter box 1001, and the filter box 1001 is fixedly connected to the transmission pipe 12;

[0031] Specifically, the sewage first enters through the connection to the feed pipe 3 and enters the inside of the filter barrel 6 for filtration treatment, and then the filtered clean water is discharged through the discharge pipe 4. During this process, the pressure gauge 7 can monitor the pressure change inside the filter barrel 6. Once the set value is reached, the controller 11 will start the equipment to perform a backwashing operation on the filter barrel 6. At the same time, by starting the sewage pump 9, the sewage inside the filter barrel 6 can be discharged through the sewage discharge pipe 8, and then the sewage is transmitted to the inside of the filter box 1001. Inside the filter box 1001, a filter box 1002 is equipped, and through its cooperative action, multiple filtrations of the sewage are realized. Finally, by opening the switch valve 13, the filtered sewage can be discharged from the system. This design not only realizes the efficient filtration and cleaning of sewage, but also ensures the stable operation and sustainable treatment of the system.

[0032] Referring to Figure 1 - Figure 3 , a turntable 14 is rotatably connected inside the fixed plate 5, and a limiting hole 15 is formed through the turntable 14; a speed reducer 16 is fixedly connected to the upper surface of the top cover 2, and a transmission shaft 17 is fixedly connected to the output end of the speed reducer 16; a cross-shaped limiting block 18 is fixedly connected to the lower surface of the transmission shaft 17, and the cross-shaped limiting block 18 is slidably connected to the inner wall of the limiting hole 15; a fixing rod 19 is fixedly connected to the outer wall of the transmission shaft 17, and a sleeve 21 is slidably connected to the outer wall of the fixing rod 19; a spring 20 is fixedly connected to one end of the fixing rod 19, and one end of the spring 20 is fixedly connected to the inner wall of the sleeve 21; a first cleaning brush 22 is fixedly connected to one side of the outer wall of the sleeve 21, and a plurality of second cleaning brushes 23 are fixedly connected to the outer wall of the transmission shaft 17;

[0033] Specifically, after the filter barrel 6 has been used for a long time, impurities that are difficult to clean may remain on its surface. To solve this problem, the speed reducer 16 can be started simultaneously during the backwashing operation. The speed reducer 16 drives the fixed rod 19 on the outer wall of the transmission shaft 17 to rotate, thereby driving the first cleaning brush 22 and the second cleaning brush 23 to rotate, making it easier to clean the impurities on the surface of the filter barrel 6. The spring 20 provided at one end of the fixed rod 19 can reduce the pressure generated during the rotation of the first cleaning brush 22 and improve the cleaning effect. In addition, by lifting the top cover 2, the cross-shaped limit block 18 can be disengaged from the limit hole 15, facilitating the disassembly of the first cleaning brush 22 to ensure the convenience and efficiency of maintenance operations.

[0034] Working principle: During use, sewage is connected to the feed pipe 3, and the sewage is sent into the interior of the filter barrel 6 through the feed pipe 3 for filtration, and then the filtered clean water is discharged through the discharge pipe 4. At this time, the pressure value inside the filter barrel 6 can be obtained through the pressure gauge 7. When the pressure value inside the filter barrel 6 reaches the set value, the device is controlled by the controller 11 to perform a backwashing operation on the filter barrel 6. At this time, by starting the sewage pump 9, it is convenient to discharge the sewage inside the filter barrel 6 through the sewage discharge pipe 8. At this time, through the transmission of the sewage discharge pipe 8, the effect of further transmitting the sewage to the interior of the filter box 1001 is achieved. Through the cooperation of the filter box 1002 inside the filter box 1001, the effect of multiple filtration is realized. By opening the switch valve 13, the filtered sewage can be discharged.

[0035] Secondly, when the filter barrel 6 is used for a long time, impurities that are difficult to clean will remain on its surface. During the backwashing operation, the speed reducer 16 can be started simultaneously. The speed reducer 16 drives the fixed rod 19 on the outer wall of the transmission shaft 17 to rotate, and the fixed rod 19 drives the first cleaning brush 22 and the second cleaning brush 23 to rotate, thereby achieving the effect of facilitating the cleaning of the filter barrel 6. Through the spring 20 provided at one end of the fixed rod 19, the effect of facilitating the reduction of the pressure generated by the rotation of the first cleaning brush 22 is achieved. By lifting the top cover 2, the cross-shaped limit block 18 can be disengaged from the limit hole 15, and then the effect of disassembling the first cleaning brush 22 is realized.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
