[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] like Figure 1-3The diagram shows a material filtration and circulation device, comprising a circulating water tank 2. A bottom valve 3 is installed at the bottom of the tank 2. The bottom valve 3 is connected to a drain valve 4 and the inlet of a magnetic circulation pump 5 via a three-way pipe. The outlet of the magnetic circulation pump 5 is connected to the inlet of a membrane assembly 6 via a pipe. The outlet of the membrane assembly 6 is connected to a pressure regulating valve 8 and a discharge valve 10 via a three-way pipe. The other end of the pressure regulating valve 8 is connected to a pipe extending to the top of the circulating water tank 2. The outlet of the membrane assembly 6 is connected to a drain valve 11 and a circulation valve via a three-way pipe. 12. The circulation valve 12 is connected to the waste liquid valve 13 and the backwash valve 14 via a three-way pipe. The cleaning water is repeatedly filtered through the membrane assembly 6 via the circulation pipeline, separating materials from the cleaning water. This allows the water to be circulated for cleaning, reducing water consumption and improving cleaning efficiency. The circulating water storage tank 2 and the magnetic circulation pump 5 are mounted on the mounting frame 1. The mounting frame 1, with pipe clamps, supports the pipes connecting the valves. The mounting frame 1 securely connects and supports the various parts of the device, ensuring a neat and stable setup and reliable operation. A diaphragm pressure gauge 7 is installed on the membrane assembly 6. The contact of the diaphragm pressure gauge 7 communicates with the cavity inside the membrane of the membrane assembly 6. A pressure gauge 16 is installed on the pipe between the pressure regulating valve 8 and the membrane assembly 6. The diaphragm pressure gauge 7 and the pressure gauge 16 can monitor and provide feedback on the pressure difference between the inside and outside of the filter membrane of the membrane assembly 6, allowing the operator to judge and adjust the filtration pressure accordingly to ensure the filtration effect. An electronic flow meter 9 is installed on the pipe connected to one end of the pressure regulating valve 8. The electronic flow meter 9 can directly and accurately determine the flow rate of the water treated by the filter membrane in the membrane assembly 6. The volume allows personnel to accurately and regularly position, maintain, and replace the membrane tube assembly 6. A control box 15 is installed on the mounting frame 1. The control box 15 is electrically connected to the magnetic circulation pump 5 and the electronic flow meter 9. The operator can conveniently control the operating status of the electrical appliances in the system through the control box 15. The backwash valve 14 is connected to a compressed air pipeline. After backwashing the membrane tube assembly 6 with clean water connected to the waste liquid valve 13, the backwash valve 14 can be opened to use compressed air to further blow away the material liquid on the surface of the filter membrane, improve the cleanliness of the system, and avoid contamination.

[0028] The working principle of this utility model is as follows: The feed liquid and cleaning liquid in the reactor to be cleaned are placed into the circulating water storage tank 2. Then, the drain valve 4, discharge valve 10, and circulation valve 12 are closed, while the tank bottom valve 3, pressure regulating valve 8, and drain valve 11 are opened. A hose is used to connect the drain valve 11 to a container for collecting clean water. The magnetic circulation pump 5 is started. When the magnetic circulation pump 5 is working, it draws the cleaning liquid from the circulating water storage tank 2 and sends the cleaning liquid into the membrane assembly 6 for filtration. By adjusting the valve size of the pressure regulating valve 8 and observing the pressure readings of the diaphragm pressure gauge 7 and pressure gauge 16, the cleaning liquid is filtered through the filter membrane in the membrane assembly 6 at a suitable pressure. When the cleaning liquid passes through the membrane assembly 6, molecules in the feed liquid with a size larger than the membrane pore size are trapped inside the filter membrane, while smaller water molecules flow through the micropores in the filter membrane towards the drain valve 11 under the action of water pressure, thereby achieving filtration of the cleaning liquid. The clean water can be circulated for cleaning, while the filtered liquid is returned to the circulating water storage tank 2 via the pressure regulating valve 8 and electronic flow meter 9, achieving circulating filtration. When it is necessary to discharge the filtered liquid remaining in the system, the discharge valve 10 is opened, the magnetic circulation pump 5 is activated, and the drain valve 11 is closed, allowing the liquid collected in the circulating water storage tank 2 to be pumped out through the discharge valve 10. When it is necessary to clean the membrane body of the membrane assembly 6, ensure that the drain valve 4, pressure regulating valve 8, and drain valve 11 are activated. With backwash valve 14 closed, connect the clean water pipe to waste liquid valve 13 and supply water to waste liquid valve 13. The cleaning water then enters the outside of the membrane body of membrane assembly 6 after passing through circulation valve 12. Under water pressure, it enters the inside of the membrane body and washes away the macromolecules blocking the membrane micropores. The wastewater is then discharged through discharge valve 10. Finally, close waste liquid valve 13 and open backwash valve 14 to allow compressed air to enter the system through backwash valve 14 to blow away the residual waste liquid on the filter membrane.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
