[0043] Embodiment 1
[0044] This embodiment provides a reverse osmosis membrane shell inner wall cleaning device, see Figure 1 , including a mobile mechanism 1, a flushing mechanism 2 and a spraying mechanism 3. The flushing mechanism 2 and the spraying mechanism 3 are arranged on the mobile mechanism 1. Specifically, a plurality of universal wheels 11 may be arranged below the mobile mechanism 1. More specifically, the mobile mechanism 1 is a movable cleaning vehicle. Figure 1 The flushing mechanism 2 includes a water tank 21, a water inlet pipeline 22 and a water pump 23. The water pump 23 is provided with a water pump water inlet end 231 and a water pump water outlet end 232. One end of the water inlet pipeline 22 is connected to the water tank 21, and the other end is connected to the water pump water inlet end 231. Specifically, a water inlet valve 221 is provided on the water inlet pipeline 22, and the water inlet valve 221 is used to control the amount of water entering the spray mechanism 3, so as to control the cleaning strength of the spray mechanism 3 on the inner wall of the reverse osmosis membrane shell.
[0045] The parameters of each mechanism in the flushing mechanism 2 are as follows: the volume of the water tank 21 is 300-700L, the flow rate of the water pump 23 is 1-3m 3 / h, the lift of the water pump 23 is 30-50m; preferably, the volume of the water tank 21 is 500L, the flow rate of the water pump 23 is 2m 3 / h, the lift of the water pump 23 is 40m.
[0046] Continue reading Figure 1 In a supplementary embodiment, the flushing mechanism 2 also includes a drainage pipe 24, one end of the drainage pipe 24 is connected to the water tank 21, and the other end passes through the mobile mechanism 1 for sewage discharge. A drainage valve 241 is provided on the drainage pipe 24, and the drainage valve 241 is used to drain the remaining water in the water tank.
[0047] Continue reading Figure 1, the spray mechanism 3 includes a spray pipe 31 and a spray bracket 32. The spray pipe 31 is provided with a spray pipe water inlet end 311 and a spray pipe water outlet end 312, the spray pipe water inlet end 311 is connected to the water pump water outlet end 232, the spray pipe water outlet end 312 is used to be arranged in the inner wall of the reverse osmosis membrane shell, and the spray bracket 32 is arranged on the spray pipe 31 near the spray pipe water outlet end 312. A spray head 33 is provided on the spray pipe water outlet end 312. Specifically, the spray head 33 is a stainless steel 360° spray ball, which can evenly clean the inner wall of the reverse osmosis membrane shell and improve the cleaning effect. It is worth noting that the spray pipe 31 is a hose. When the water flow rate is not large, it is difficult to move in the inner wall of the reverse osmosis membrane shell, which will cause stacking. Therefore, the spray bracket 32 should have a certain hardness, for example, the material of the spray bracket 32 is stainless steel, to ensure that the spray pipe 31 can be driven to move in the inner wall of the reverse osmosis membrane shell. In addition, the spray head 33 can be fixed at the center of the spray bracket 32. With this arrangement, the inner wall of the reverse osmosis membrane shell can be cleaned more evenly.
[0048] The parameters of the spray pipe 31 are set as follows: the spray pipe 31 generally uses a high-pressure hose, the nominal diameter of the spray pipe 31 is any one of DN 25, DN 32 or DN 40, the nominal pressure of the spray pipe 31 is PN 10, PN 20 or PN 30, and the length of the spray pipe 31 is 10 to 20 meters. Preferably, the nominal diameter of the spray pipe 31 is DN 25, the nominal pressure of the spray pipe 31 is PN10, and the length of the spray pipe 31 is 10 meters.
[0049] In a supplementary embodiment, the spray mechanism 3 further includes a pipeline tray 34, and the spray pipe 31 is arranged around the pipeline tray 34. The pipeline tray 34 can make a part of the spray pipe 31 neatly arranged in a circular ring shape, saving space on the mobile mechanism 1. In another supplementary embodiment, a check valve 35, a water outlet valve 36 and a pressure gauge 37 are also provided on the spray pipe 31 near the water inlet end 311 of the spray pipe. The check valve 35 is used to prevent the water in the spray pipe 31 from flowing back into the water pump 23 after the water pump 23 stops; the water outlet valve 36 plays a shut-off role, allowing water to pass through or intercepting the water; the pressure gauge 37 of the control spray pipe 31 is used to detect the real-time pressure of the spray pipe 31 to ensure that the spray pipe 31 is in a safe use state.
[0050] This embodiment also provides a method for using the reverse osmosis membrane shell inner wall cleaning device, and the specific method is as follows:
[0051] 1) Push the moving mechanism 1 to the reverse osmosis membrane shell to be cleaned. The reverse osmosis membrane shell is generally placed on a fixed bracket.
[0052] 2) Open the covers at both ends of the reverse osmosis membrane shell to be cleaned, so that the reverse osmosis membrane shell is in a state of opening at both ends, and insert the spray bracket 32 together with the spray pipe 31 into the reverse osmosis membrane shell through one end of the reverse osmosis membrane shell.
[0053] 3) Slowly push the spray pipe 31 to the other end outlet of the reverse osmosis membrane shell. During cleaning, water is sprayed out through the route of water tank 21->water inlet pipe 22->water pump 23->spray pipe 31->spray head 33 to complete the cleaning of the inner wall of the reverse osmosis membrane shell. The sewage flows into the ground through the opening at the other end of the reverse osmosis membrane shell. Generally, there will be a corresponding drainage trough on the ground.
[0054] 4) After cleaning, check whether the inner wall of the reverse osmosis membrane shell is clean. If it is clean, continue to clean the inner walls of other reverse osmosis membrane shells.
[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
