DETAILED DESCRIPTION

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0032] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, it is an embodiment provided by the utility model: a circulating concentration membrane cleaning device, including a base 1, a chassis 2 is fixedly connected to the top of the base 1, an inner tank 3 is fixedly connected to the top of the chassis 2, an outer tank 4 is slidably connected to the outer wall of the inner tank 3, the height of the outer tank 4 is higher than the height of the inner tank 3, and a permeate storage tank is composed of the chassis 2, the inner tank 3 and the outer tank 4. The outer wall of the outer tank 4 is fixedly connected to an outer shell 5, the height of the outer shell 5 is the same as the height of the outer tank 4, both ends of the bottom of the outer shell 5 are vertically penetrated by threaded sleeves 6, both ends of the bottom of the outer shell 5 are provided with through holes that penetrate up and down, the outer wall of the threaded sleeve 6 is inserted and fixed in the through hole, both ends of the top of the chassis 2 are fixedly connected to a rotating shaft 7, the movable ends of the rotating shaft 7 are rotatably connected to a gear shaft 8, and the outer end of the gear shaft 8 An internal gear swivel 9 is meshed with the wall, and a threaded rod 10 is fixedly connected to the top of the gear shaft 8. By setting a connection structure between the gear shaft 8 and the internal gear swivel 9, the rotating internal gear swivel 9 can rotate with the gear shaft 8. At this time, the rotation direction and speed of the two sets of gear shafts 8 are the same. The outer walls of the threaded rod 10 are threadedly connected to the inner wall of the threaded sleeve 6. By setting a connection method between the threaded rod 10 and the threaded sleeve 6, when the internal gear swivel 9 rotates with the gear shaft 8, the threaded rod 10 above the gear shaft 8 will also rotate together. At this time, the threaded sleeve 6 will move up and down on the outer wall of the rotating threaded rod 10, and the outer shell 5 and the outer tank 4 will also move up and down together, thereby playing a role in adjusting the size of the storage tank.

[0033] Reference Figure 2 , Figure 3 and Figure 6 As shown, the front ends of the outer tank 4 and the outer shell 5 are penetrated by an overflow pipe 11. By setting the overflow pipe 11, the excess permeate in the storage tank can be transported to a designated position. A liquid outlet pipe 12 is vertically penetrated in the chassis 2. A valve 13 is fixedly connected to the end of the liquid outlet pipe 12. A first liquid infusion pipe 14 is penetrated at the center of the front end of the valve 13. A first cleaning pump 15 is movably connected to the front end of the outer wall of the first liquid infusion pipe 14. When the valve 13 is opened, the permeate in the storage tank will flow into the first cleaning pump 15 through the first liquid infusion pipe 14. The output end of the first cleaning pump 15 is fixedly connected to the second liquid infusion pipe 16. The end of the second infusion pipe 16 is fixedly connected to a safety filter 17, and a third infusion pipe 18 passes through the top of one side of the inner wall of the safety filter 17, and the end of the third infusion pipe 18 is fixedly connected to a membrane system box 19. A circulating cleaning tank 20 is installed at the rear end of the membrane system box 19, and a fourth infusion pipe 21 passes through the bottom end of the other side of the inner wall of the membrane system box 19, and the end of the fourth infusion pipe 21 is fixedly connected to a drain valve 22, and the output end of the drain valve 22 is fixedly connected to a drain pipe 23, and the end of the drain pipe 23 is fixedly connected to a factory drainage system 24, and the end of the overflow pipe 11 is arranged directly above the factory drainage system 24.

[0034] Reference Figure 1 and Figure 2As shown, after the equipment production is completed, the collected permeate is first used to flush the inside of the membrane system box 19. The permeate passes through the first cleaning pump 15 and the safety filter 17 and enters the membrane system box 19, and directly enters the factory drainage system 24 from the drainage pipe 23 in the drainage valve 22. In this step, all the water in the permeate storage tank is used up. After the permeate flushing is completed, normal temperature or high temperature pure water is added to the circulation cleaning tank 20, and the system is continued to be flushed until the water flushed out of the membrane system box 19 becomes transparent. A circulation isolation valve 25 is passed through the top center of the drainage valve 22. During the above flushing process, the circulation isolation valve 25 remains closed, so that the water flow is directly pushed forward for flushing, which is easier to flush, and the residual cleaning liquid is also lower, which is more water-saving. The overflow pipe 11 can directly transport the excess permeate to the factory drainage system 24.

[0035] Reference Figure 2 , Figure 3 and Figure 7 As shown, the output end of the circulation isolation valve 25 is fixedly connected to the fifth infusion pipe 26, the end of the fifth infusion pipe 26 is fixedly connected to the large-flow circulation pump 27, the output end of the large-flow circulation pump 27 is fixedly connected to the sixth infusion pipe 28, the end of the sixth infusion pipe 28 vertically penetrates the top center of the circulation cleaning tank 20, the extended end of the sixth infusion pipe 28 is rotatably connected to the rotating spray ball 29, the top of one side of the inner wall of the circulation cleaning tank 20 penetrates the second cleaning pump 30, the output end of the second cleaning pump 30 is fixedly connected to the seventh infusion pipe 31, the end of the seventh infusion pipe 31 penetrates the top of one side of the inner wall of the membrane system box 19, the rear end of the circulation cleaning tank 20 is fixedly connected to the dosing tank 32, the top center of the dosing tank 32 penetrates the dosing pump 33, the output end of the dosing pump 33 is fixedly connected to the drug delivery pipe 34, and the top of the drug delivery pipe 34 penetrates the rear end of the inner wall of the circulation cleaning tank 20.

[0036] Reference Figure 2 , Figure 3 and Figure 7As shown, by setting the structure of the circulation isolation valve 25, the large-flow circulation pump 27, the second cleaning pump 30, the dosing tank 32 and the dosing pump 33, after the flushing is completed, high-temperature pure water is added to the circulation cleaning tank 20, the system automatically adds medicine, opens the circulation isolation valve 25, starts the second cleaning pump 30 and the large-flow circulation pump 27, and the water flow no longer enters the factory drainage system 24 through the sewage pipe 23, but circulates back to the circulation cleaning tank 20 for repeated drug washing. After the drug washing is completed, the system automatically opens all sewage valves 22 and drains water by gravity. By setting the rotating spray ball 29, when the drainage is about to end, pure water is automatically used to pass through the rotating spray ball 29 for a short time. Rinse the circulating cleaning tank 20 temporarily to flush the remaining stains, foam and cleaning liquid in the system into the sewer. After the chemical washing is completed, continue to repeat the pure water flushing process until the system is clean. When adding pure water to the circulating cleaning tank 20, the pressurized water flow impacts the rotating spray ball 29 set in the tank, so that the water flow is spirally sprayed in every corner of the tank body, so that the inner wall of the tank is completely rinsed clean. In general systems, the setting of the rotating spray ball 29 will cause the water flow rate to decrease. In order to avoid this problem, a bypass is set on the pipe in front of the rotating spray ball 29, which not only plays the role of the rotating spray ball 29, but also avoids the problem of reduced water flow.
