Furthermore, the cleaning solution is mostly for single use and lacks a recycling design. Utility Model Content

[0005] The purpose of this invention is to provide a precise dosing and cleaning device for reverse osmosis membranes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reverse osmosis membrane precision dosing and cleaning device, including a storage tank, the bottom of which is vertically inserted through the middle of the metering cylinder, the outlet end of which is horizontally inserted through one side of a container, and the other side of the container having a liquid outlet pipe horizontally inserted through the middle of the container, with a diversion pipe at the outlet end of the liquid outlet pipe.

[0007] The container is equipped with a reverse osmosis membrane.

[0008] The beneficial effects of this utility model are as follows: the top injection pipe of the medicine storage tank facilitates the injection of medicine, the bottom discharge pipe cooperates with the flow control valve to accurately control the amount of medicine flowing into the metering cylinder, the scale on the outer wall of the metering cylinder facilitates precise adjustment of the amount of medicine, the bottom delivery pipe can stably deliver the medicine to the placement container through valve A and pump A, the diversion pipe is divided into a return pipe and a drain pipe, and with the help of pump B, valve C and return valve, the cleaning solution can be recycled and discharged, which can save medicine and improve cleaning efficiency.

[0009] To achieve precise control of the amount of medicine discharged, the injection pipe at the top of the medicine storage tank is used to inject the medicine, while the discharge pipe at the bottom of the medicine storage tank, in conjunction with the flow control valve, is used:

[0010] The following configuration is further provided: a drug injection pipe is vertically inserted through the middle of the top of the drug storage tank, a drug discharge pipe is provided at the bottom of the drug storage tank, a flow control valve is provided on the outer wall of the drug discharge pipe, and the bottom end of the drug discharge pipe is vertically inserted through the middle of the top of the metering cylinder.

During the cleaning process, clean water can be injected to rinse the reverse osmosis membrane after the cleaning solution is applied. Valve B can control the water inlet volume and timing, and can be flexibly adjusted according to actual cleaning needs, thereby improving the flexibility and effectiveness of cleaning.

[0018] To achieve the recycling and discharge switching of the cleaning solution through the cooperation of the return pipe and drain pipe in the diversion pipe, as well as the liquid pump B, valve C, and the return valve on the drain pipe, and to improve cleaning efficiency:

[0019] Further configuration: the diversion pipe is divided into a return pipe and a drain pipe, the outer walls of the return pipe and the drain pipe are respectively equipped with a valve C and a return valve, the outlet end of the return pipe extends laterally through one side of the medicine storage tank, and the outer wall of the return pipe is equipped with a liquid pump B.

The liquid pump B and valve C on the return pipe and the return valve on the drain pipe work together to realize the recycling and discharge switching of the cleaning liquid. This allows the cleaning liquid to return to the storage tank to continue to participate in the circulation, saving the amount of liquid used. It also allows the waste liquid after cleaning to be discharged directly, making it convenient to replace the cleaning liquid or complete the cleaning operation, thus improving the cleaning efficiency.
