[0022] An automated SiC membrane device, such as Figures 1-5As shown, the system includes an outer casing 1, a protective door 3, a control panel 4, a drain pipe 7, an inlet pipe 8, a filter inlet valve 801, a basket filter 9, a circulating cleaning water pump 10, a primary membrane module 11, a secondary membrane module 12, a purified liquid valve 13, a purified liquid outlet pipe 14, a concentrate reflux control system, an automatic sampler 24, and a connecting pipe 25. The outer casing 1 has a protective door 3 on its exterior, and a control panel 4 is mounted on the protective door 3. An inlet pipe 8 is located on the left side of the outer casing 1, penetrating the casing 1. A filter inlet valve 801 is located on the outside of the inlet pipe 8, and the inlet pipe 8 is connected to a concentration tank. The end of the inlet pipe 8 furthest from the concentration tank is connected to a basket filter 9. A circulating cleaning water pump 10 is connected to the right side of the basket filter 9. The water delivery end of the circulating cleaning water pump 10... A primary membrane core assembly 11 is connected, and a connecting pipe 25 is connected to the bottom of the primary membrane core assembly 11. The end of the connecting pipe 25 away from the primary membrane core assembly 11 is connected to a secondary membrane core assembly 12. A concentrate reflux control mechanism is provided on the rear side of the secondary membrane core assembly 12. A purified liquid outlet pipe 14 is connected to the front side of the secondary membrane core assembly 12. An automatic sampler 24 and a purified liquid valve 13 are provided on the outside of the purified liquid outlet pipe 14. The distance between the automatic sampler 24 and the secondary membrane core assembly 12 is shorter than the distance between the purified liquid valve 13 and the secondary membrane core assembly 12. The automatic sampler 24 has a built-in valve and a turbidity sensor. The right end of the purified liquid outlet pipe 14 is connected to a drain pipe 7. The filter inlet valve 801, the circulating cleaning water pump 10, the purified liquid valve 13, and the automatic sampler 24 are all electrically connected to the control panel 4.

[0023] like Figure 5 As shown, the concentrate reflux control mechanism includes a concentrate reflux pressure sensor 21, a concentrate reflux pipe 22, and a concentrate reflux valve 23. The concentrate reflux pipe 22 is located on the rear side of the secondary membrane core assembly 12. The concentrate reflux valve 23 and the concentrate reflux pressure sensor 21 are located on the outside of the concentrate reflux pipe 22. The end of the concentrate reflux pipe 22 away from the secondary membrane core assembly 12 is connected to the top of the basket filter 9. The concentrate reflux valve 23 and the concentrate reflux pressure sensor 21 are both electrically connected to the control panel 4.

[0024] like Figure 1 As shown, it also includes a float flow meter 6 and a foot support 2. The float flow meter 6 is located on the outside of the drain pipe 7. A flow meter slot 5 is opened on the front side of the housing 1. The float flow meter 6 is located on the flow meter slot 5. The flow meter slot 5 allows the operator to directly observe the position of the float and understand the current flow situation in real time. The float flow meter 6 has a built-in liquid level float switch, which is electrically connected to the control panel 4. The bottom of the housing 1 is equipped with a foot support 2 to ensure that the equipment is placed stably to adapt to different installation environments.

[0025] like Figure 3-5As shown, it also includes a cleaning reflux valve 18, a cleaning reflux pipe 19, a cleaning inlet valve 26, and an acid / alkali washing tank 20. The cleaning reflux pipe 19 is connected to the right side of the secondary membrane core assembly 12. The cleaning reflux valve 18 is provided on the outside of the cleaning reflux pipe 19. The acid / alkali washing tank 20 is provided on the top of the inner side of the outer casing 1. One end of the cleaning reflux pipe 19 away from the secondary membrane core assembly 12 is connected to one end of the acid / alkali washing tank 20. The other end of the acid / alkali washing tank 20 is connected to the basket filter 9. The cleaning reflux valve 18 and the cleaning inlet valve 26 are both electrically connected to the control panel 4.

[0026] like Figure 4 As shown, it also includes a buffer pressure sensor 15 and a buffer bottle 16. The right end of the purified liquid outlet pipe 14 is connected to the buffer bottle 16. The buffer pressure sensor 15 is installed on the outside of the buffer bottle 16. The buffer pressure sensor 15 is electrically connected to the control panel 4. The liquid flowing out of the purified liquid outlet pipe 14 will be stored in the buffer bottle 16 first. When the flow rate changes instantaneously, the buffer bottle 16 can smooth the flow rate, ensuring that the float flow meter 6 and the drain pipe 7 will not be affected by the sudden change in flow rate. The buffer pressure sensor 15 monitors the pressure status in the buffer bottle 16 in real time and feeds the data back to the control panel 4. The control panel 4 adjusts the opening and closing degree of the filter inlet valve 801 according to the pressure data.

[0027] like Figure 2 As shown, it also includes an air backwash valve 17. The buffer bottle 16 is equipped with an air backwash valve 17 on its top. The air backwash valve 17 is electrically connected to the control panel 4. After cleaning the primary membrane core assembly and the secondary membrane core assembly with cleaning fluid, the control panel 4 opens the air backwash valve 17 to introduce compressed air to flush the drain pipe 7, remove dirt and particles from the drain pipe 7, and prevent blockage.

[0028] Open the filter inlet valve 801 via control panel 4 and start the circulating cleaning water pump 10. The liquid in the concentration tank flows into the basket filter 9 through the inlet pipe 8 for preliminary filtration. The basket filter 9 performs preliminary filtration, removing larger particles and other impurities. The liquid then enters the primary membrane module 11 and the secondary membrane module 12 for fine filtration under the suction of the circulating cleaning water pump 10. The valve is activated periodically, and the turbidity sensor detects whether the liquid quality meets the standards. If it does, the purified liquid valve 13 is opened, and the liquid flows to the outlet pipe through the purified liquid outlet pipe 14. If it does not meet the standards, the liquid continues to flow... Filtration occurs within the primary membrane module 11 and the secondary membrane module 12. As liquid is continuously pumped into the secondary membrane module 12, if the liquid level within the secondary membrane module 12 is not yet at the set threshold, the pressure within the secondary membrane module 12 will continuously rise. The concentrate reflux pressure sensor 21 continuously monitors the pressure within the secondary membrane module 12. If the pressure reaches the preset value, the control panel 4 will close the filter inlet valve 801 and then open the concentrate reflux valve 23. The liquid returns to the concentration tank through the concentrate reflux pipe 22. Once the pressure returns to normal, the control panel 4 will open the filter inlet valve 801 and close the concentrate reflux valve 23. Before flowing out of the drain pipe 7, the liquid passes through the float flowmeter 6. The level float switch within the float flowmeter 6 detects the flow rate of the liquid in this equipment. If the flow rate is too low or too high, the level float switch will trigger an alarm on the control panel 4, reminding the operator to stop the operation of the equipment.

[0029] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
