[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 4 As shown;

[0035] An energy-saving RO electrophoresis recovery system comprises a cylinder 1, wherein the interior of the cylinder 1 is hollow, and further comprises:

[0036] The sealing cap 2 has two upper and lower groups, which are symmetrically distributed, and the inner wall of the sealing cap 2 is sealed and connected to the cylinder 1 through a thread;

[0037] The liquid inlet and outlet pipes 3 have two groups, the upper and lower groups of the liquid inlet and outlet pipes 3 are symmetrically distributed, the liquid inlet and outlet pipes 3 are fixedly connected to the cover 2, and the hollow part of the liquid inlet and outlet pipes 3 is connected to the cover 2;

[0038] A circular slide rail 4, the inner wall of which is fixedly connected to the outer wall of the cylinder 1, and the circular slide rail 4 has two groups, upper and lower, and is symmetrically distributed;

[0039] Cleaning plates 5, there are two groups of cleaning plates 5, the cleaning plates 5 are arranged inside the cylinder 1, the cleaning plates 5 are symmetrically distributed inside the cylinder 1, and the cleaning plates 5 are made of a material that can be adsorbed by magnetic force;

[0040] An arc-shaped protrusion 6, wherein the arc-shaped protrusion 6 is evenly fixed to the inner wall of the cleaning plate 5;

[0041] A filter element 7, wherein the filter element 7 is disposed in the cylinder 1, and the surface of the filter element 7 is wrapped by the inner wall of the cylinder 1;

[0042] The interior of the cleaning plate 5 is hollow, and the hollow opening of the cleaning plate 5 is located at one end of the rotation direction of the cleaning plate 5;

[0043] The end of the cleaning plate 5 away from the hollow opening of the cleaning plate 5 is designed to be inclined to drain the liquid and impurities;

[0044] A through pipe 9 is fixedly connected to the bottom of the cleaning plate 5, the through pipe 9 is connected to the hollow part of the cleaning plate 5, and a one-way valve 10 is arranged inside the through pipe 9;

[0045] The device is used in conjunction with an electrophoretic paint recovery machine, and the device is used to replace the reverse osmosis membrane in the original electrophoretic paint recovery machine that is easy to clog and difficult to clean. The inlet and outlet pipes 3 of the device are connected to the inlet and outlet pipes in the electrophoretic paint recovery machine, so that when the waste water extracted by the electrophoretic paint recovery machine circulates in the electrophoretic paint recovery machine, it will continuously enter the cylinder 1 from the inlet and outlet pipes 3 on the lower cover 2. When the waste water passes through the cylinder 1, the impurities in the waste water will be blocked and filtered by the filter element 7 in the cylinder 1, and then the filtered waste water will be discharged from the inlet and outlet pipes 3 on the upper cover 2 back to the electrophoretic paint recovery machine, thereby completing the original function of filtering the electrophoretic waste water of the electrophoretic paint recovery machine. When the filter element 7 needs to be backwashed and cleaned, the circular slide rail 4 is energized and rotated, and the slider in the circular slide rail 4 adsorbs the cleaning plate 5 in the cylinder 1 through magnetic force, and makes it rotate along the inner wall of the cylinder 1 as the slider in the circular slide rail 4 rotates, and the backwash water is discharged from the upper cover 2 The inlet and outlet liquid pipes 3 on the upper side enter the cylinder 1, and the backwash water is continuously input into the cylinder 1 to wash the filter element 7 in the cylinder 1. At the same time, when the cleaning plate 5 rotates, the arc-shaped protrusions 6 also rotate, and the arc-shaped protrusions 6 circulate and squeeze the filter element 7 in the cylinder 1 to squeeze out the impurities blocked in the filter element 7. The extruded impurities flow into the electrophoretic paint recovery machine from the inlet and outlet liquid pipes 3 on the lower cover 2 with the backwash water, and then the sewage valve of the electrophoretic paint recovery machine is opened, and the backwash water and the impurities on the filter element 7 will be discharged from the sewage valve of the electrophoretic paint recovery machine, thereby cleaning the filter element 7 and reducing the backwashing time. The filter element 7 does not need to be taken out for cleaning, and the backwashing efficiency and the service life of the filter element 7 are effectively increased. After the cleaning is completed, the circular slide rail 4 is powered off, so that the slider of the circular slide rail 4 stops rotating, and the cleaning plate 5 also stops rotating, so as to avoid unnecessary influence on the electrophoretic waste liquid recovery device during normal use;

[0046] In order to prevent the impurities from sticking to the inner wall of the cylinder 1, when the cleaning plate 5 rotates, the outer wall of the cleaning plate 5 will scrape the inner wall of the cylinder 1. The cleaning plate 5 is hollow, and the opening is located at one end of the rotation direction of the cleaning plate 5. The scraped impurities will enter the hollow part from the opening, and the liquid containing impurities squeezed out from the filter element 7 by the arc-shaped protrusion 6 will also enter the inner hollow part of the cleaning plate 5 from the opening of the cleaning plate 5. The rotation of the cleaning plate 5 can make the impurities and liquid containing impurities scraped off by the outer wall of the cleaning plate 5 against the inner wall of the cylinder 1 continue to flow into the hollow part of the cleaning plate 5. Since the cleaning plate 5 is inclined at one end away from the hollow opening of the cleaning plate 5, the cleaned impurities and the liquid containing impurities squeezed out by the arc-shaped protrusion 6 will flow into the hollow part along the inclined end after continuously flowing into the hollow part. The liquid flows downward to the bottom of the cleaning plate 5. A through pipe 9 is provided at the bottom of the cleaning plate 5. A one-way valve 10 is provided inside the through pipe 9. The liquid enters the through pipe 9 and is then discharged to the inner wall of the lower cover 2 after passing through the one-way valve 10. Then, it flows along the inner wall of the lower cover 2 to the liquid inlet and outlet pipe 3 on the lower cover 2 and is then discharged from the cylinder 1 to clean the inner wall of the cylinder 1. The use of the one-way valve 10 can prevent the waste liquid to be filtered from flowing into the hollow part of the cleaning plate 5 from the through pipe 9 when the present invention is used in conjunction with the electrophoresis waste liquid recovery device, and from being adsorbed by the middle or upper part of the filter element 7 when being discharged from the hollow opening of the cleaning plate 5, instead of being adsorbed by the bottom end of the filter element 7 and then discharged from the upper part of the filter element 7, thereby shortening the filtration process of the waste water adsorbed by the filter element 7 and reducing the filtration effect.

[0047] As a specific embodiment of the present invention, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the middle part of the arc-shaped protrusion 6 is hollow;

[0048] Each group of arc-shaped protrusions 6 is staggered with the arc-shaped protrusions 6 on the opposite side;

[0049] The cleaning plates are fixedly connected by fixing rods 8;

[0050] When in use, the cleaning plate 5 rotates, and the staggered arc-shaped protrusions 6 can fully squeeze the filter element 7 in the cylinder 1 to increase the cleaning efficiency. The hollow design of the arc-shaped protrusions 6 enables the impurities and liquid squeezed out by the arc-shaped protrusions 6 to flow downward along the hollow part when squeezing the filter element 7, and then flow to the opening of another arc-shaped protrusion 6 on the lower side, until it flows to the lower side cover 2 and is discharged from the cylinder 1 through the liquid inlet and outlet pipes 3 on the lower side cover 2. The hollow design can effectively increase the amount of impurities and liquid passing through, and prevent the impurities from being squeezed out of the filter element 7 without effective circulation and being adsorbed by the filter element 7, causing secondary clogging. In order to prevent the cleaning plates 5 from being misaligned when the inner wall of the cylinder 1 rotates, the cleaning plates 5 are fixedly connected by fixing rods 8 to achieve synchronous rotation and stop.

[0051] As a specific embodiment of the present invention, Figures 2 to 5 As shown, one end of the cleaning plate 5 in the rotation direction is designed to be arc-shaped;

[0052] When in use, the arc-shaped design of one end of the cleaning plate 5 in the rotation direction allows the cleaning plate 5 to easily slide across the surface of the filter element 7 in the cylinder 1 when rotating, without scratching the filter element 7, thereby causing damage to the filter element 7, resulting in a reduced service life of the filter element 7 and increased production consumption.

[0053] As a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, the top of the filter element 7 is fixedly connected to the inner wall of the upper cover 2;

[0054] The upper end of the arc-shaped protrusion 6 is designed to be inclined toward the side close to the cleaning plate 5;

[0055] When in use, when the narrow cleaning plate 5 rotates to squeeze the filter element 7, the top of the filter element 7 is fixedly connected to the inner wall of the upper cover 2 to prevent the cleaning plate 5 from contacting with the filter element 7 to generate a slight friction force that drives the filter element 7 to rotate slightly, resulting in a reduction in the squeezing and cleaning effect of the cleaning plate 5 on the filter element 7. In addition, when the arc-shaped protrusion 6 squeezes the filter element 7, the impurities and liquid squeezed out of the filter element 7 will slide toward the cleaning plate 5 along the inclined upper end surface of the arc-shaped protrusion 6 when falling on the upper end surface of the arc-shaped protrusion 6, and then fall on the inner wall of the lower cover 2 after passing through the hollow part of each group of arc-shaped protrusions 6, preventing the impurities and liquid remaining on the upper end surface of the arc-shaped protrusion 6 from being re-absorbed by the filter element 7, thereby reducing the cleaning effect of the cleaning plate 5.

[0056] The specific workflow is as follows:

[0057] The device is used in conjunction with an electrophoretic paint recovery machine, and the device is used to replace the reverse osmosis membrane in the original electrophoretic paint recovery machine that is easy to clog and difficult to clean. The inlet and outlet pipes 3 of the device are connected to the inlet and outlet pipes in the electrophoretic paint recovery machine, so that when the waste water extracted by the electrophoretic paint recovery machine circulates in the electrophoretic paint recovery machine, it will continuously enter the cylinder 1 from the inlet and outlet pipes 3 on the lower cover 2. When the waste water passes through the cylinder 1, the impurities in the waste water will be blocked and filtered by the filter element 7 in the cylinder 1, and then the filtered waste water will be discharged from the inlet and outlet pipes 3 on the upper cover 2 back to the electrophoretic paint recovery machine, thereby completing the original function of filtering the electrophoretic waste water of the electrophoretic paint recovery machine. When the filter element 7 needs to be backwashed and cleaned, the circular slide rail 4 is energized and rotated, and the slider in the circular slide rail 4 adsorbs the cleaning plate 5 in the cylinder 1 through magnetic force, and makes it rotate along the inner wall of the cylinder 1 as the slider in the circular slide rail 4 rotates, and the backwash water is discharged from the upper cover 2 The inlet and outlet liquid pipes 3 on the upper side enter the cylinder 1, and the backwash water is continuously input into the cylinder 1 to wash the filter element 7 in the cylinder 1. At the same time, when the cleaning plate 5 rotates, the arc-shaped protrusions 6 also rotate, and the arc-shaped protrusions 6 circulate and squeeze the filter element 7 in the cylinder 1 to squeeze out the impurities blocked in the filter element 7. The extruded impurities flow into the electrophoretic paint recovery machine from the inlet and outlet liquid pipes 3 on the lower cover 2 with the backwash water, and then the sewage valve of the electrophoretic paint recovery machine is opened, and the backwash water and the impurities on the filter element 7 will be discharged from the sewage valve of the electrophoretic paint recovery machine, thereby cleaning the filter element 7 and reducing the backwashing time. The filter element 7 does not need to be taken out for cleaning, and the backwashing efficiency and the service life of the filter element 7 are effectively increased. After the cleaning is completed, the circular slide rail 4 is powered off, so that the slider of the circular slide rail 4 stops rotating, and the cleaning plate 5 also stops rotating, so as to avoid unnecessary influence on the electrophoretic waste liquid recovery device during normal use;

[0058] In order to prevent the impurities from sticking to the inner wall of the cylinder 1, when the cleaning plate 5 rotates, the outer wall of the cleaning plate 5 will scrape the inner wall of the cylinder 1. The cleaning plate 5 is hollow, and the opening is located at one end of the rotation direction of the cleaning plate 5. The scraped impurities will enter the hollow part from the opening, and the liquid containing impurities squeezed out from the filter element 7 by the arc-shaped protrusion 6 will also enter the inner hollow part of the cleaning plate 5 from the opening of the cleaning plate 5. The rotation of the cleaning plate 5 can make the impurities and liquid containing impurities scraped off by the outer wall of the cleaning plate 5 against the inner wall of the cylinder 1 continue to flow into the hollow part of the cleaning plate 5. Since the cleaning plate 5 is inclined at one end away from the hollow opening of the cleaning plate 5, the cleaned impurities and the liquid containing impurities squeezed out by the arc-shaped protrusion 6 will flow into the hollow part along the inclined end after continuously flowing into the hollow part. The liquid flows downward to the bottom of the cleaning plate 5. A through pipe 9 is provided at the bottom of the cleaning plate 5. A one-way valve 10 is provided inside the through pipe 9. The liquid enters the through pipe 9 and is then discharged to the inner wall of the lower cover 2 after passing through the one-way valve 10. Then, it flows along the inner wall of the lower cover 2 to the liquid inlet and outlet pipe 3 on the lower cover 2 and is then discharged from the cylinder 1 to clean the inner wall of the cylinder 1. The use of the one-way valve 10 can prevent the waste liquid to be filtered from flowing into the hollow part of the cleaning plate 5 from the through pipe 9 when the present invention is used in conjunction with the electrophoresis waste liquid recovery device, and from being adsorbed by the middle or upper part of the filter element 7 when being discharged from the hollow opening of the cleaning plate 5, instead of being adsorbed by the bottom end of the filter element 7 and then discharged from the upper part of the filter element 7, thereby shortening the filtration process of the waste water adsorbed by the filter element 7 and reducing the filtration effect.
