[0032] Working process of the present invention: The water machine of the present invention facilitates replacement of membrane tubes. During operation, the number of first water inlet branches 21 to be opened is determined according to the number of activated membrane tubes 5, and the valves and water pumps 22 on the corresponding first water inlet branches 21 are opened. Under the action of the water pump 22, water enters the membrane tube 5 from the first water inlet pipeline 2 through the first water inlet branch 21, the first water outlet pipeline 23, and the first water outlet branch 24 in sequence. The water can be preliminarily filtered when passing through the security filter 20 on the first water inlet branch 21. After the water is filtered by the membrane tube 5, the filtered water enters the second water outlet pipeline 3 from the second water outlet branch 31, and then enters the water tank 17 through the fourth water outlet pipe 32, and finally flows out from the water outlet pipe at the bottom of the water tank 17. The wastewater generated by the membrane tube 5 enters the third water outlet pipeline 4 from the third water outlet branch 41 and is discharged.

[0033] The water in the second water outlet branch pipe 31 and the water in the second water outlet pipeline 3 are regularly tested. Under normal circumstances, only one second water outlet branch pipe 31 is in the testing state at the same time. When the water in the second water outlet branch pipe 31 fails to pass the test, it means that the membrane tube 5 needs to be replaced. The control box 16 automatically closes the first water outlet branch pipe 24, the second water outlet branch pipe 31, and the third water outlet branch pipe 41 connected to the corresponding membrane tube 5, and reminds the maintenance personnel. After the maintenance personnel arrive at the scene, they operate the control box to open the corresponding opening and closing door 11, and the three electric clamping claws 55 corresponding to the membrane tube 5 loosen the connection assembly, and the push-pull device withdraws the membrane tube 5.

[0034] When the water in the second water outlet pipe 3 fails the inspection, the fourth water outlet pipe 32 is opened and closed, and the fifth water outlet pipe 33 is opened to discharge the water. All membrane tubes 5 are inspected simultaneously, and those that fail the inspection are processed according to the above steps, and those that pass the inspection are reopened, and then the fifth water outlet pipe 33 is closed and the fourth water outlet pipe 32 is opened.

[0035] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
