[0002] Edible vegetable oils are an indispensable nutrient in human life and an important raw material for animal feed, medicine, and industrial applications. The production of edible vegetable oils requires refining crude oil extracted from various oilseeds to remove impurities and undesirable components, thereby improving the quality and stability of the oil. This refining process consumes a large amount of water resources and generates significant amounts of wastewater, necessitating wastewater treatment.

[0003] However, existing wastewater treatment devices for vegetable oil processing have some problems in use. They are not convenient to change their operating mode for different working conditions, which reduces the efficiency of the device. At the same time, during the cleaning process, it is not convenient to thoroughly clean the inner wall of the device, which may affect the subsequent use of the device. Summary of the Invention

[0007] Preferably, two T-shaped plates are fixedly connected to the side of the L-shaped plate near the connecting frame, and U-shaped plates are fitted on both the front and rear sides of the connecting frame. T-shaped grooves are opened on both the left and right sides of the U-shaped plates, and the T-shaped plates are located in adjacent T-shaped grooves. Two magnets are fixedly connected to the corresponding side of the two U-shaped plates, and the two adjacent magnets are fitted together.

[0008] Preferably, connecting plates are fixedly connected to both the front and rear sides of the crossbar, and a second threaded hole is provided on each of the connecting plates. Two third threaded holes are provided on the side of the L-shaped plate near the connecting frame. A threaded rod is threaded into each of the second threaded holes, and the threaded rod is threaded into the adjacent third threaded hole.

[0009] Preferably, each of the first sealing frames has a connecting hole at its center, and a first connecting cover is fixedly connected to each connecting hole. Each of the first connecting covers has a second annular groove on the side away from the connecting frame, and a fourth magnetic ring is fixedly connected to each of the second annular grooves. Each of the first connecting covers is equipped with a first solenoid valve.

[0010] Preferably, limiting holes are provided at the top of the second sealing frame on the left side near the four corners. A fixing tube is fixedly connected to each limiting hole. The bottom end of the fixing tube extends into the inner cavity of the fixing frame. Four through grooves are provided on the outer edge of the fixing tube near the bottom.

[0011] Preferably, the second connecting cover has a first annular groove on the side away from the telescopic tube, and a third magnetic ring is fixedly connected in the first annular groove.

[0012] A method for treating wastewater from edible vegetable oil processing includes the following steps:

[0013] S1: When the device starts working, the device has multiple working states. When it is necessary to filter vegetable oil wastewater, the vegetable oil wastewater is first introduced into the connecting frame through the first connecting cover above. The two filter plates inside the connecting frame will filter the impurities in the vegetable oil wastewater.

[0014] S2: Then stretch the second connecting cover on the left side. The second connecting cover on the left side drives the telescopic tube on the left side to stretch, and the telescopic tube on the left side drives the flexible tube on the left side to stretch. Connect the second connecting cover on the left side to the first connecting cover below. The second connecting cover on the left side and the first connecting cover below are connected through the third magnetic ring and the fourth magnetic ring. Open the first solenoid valve below and start the pump on the left side. The filtered vegetable oil wastewater will enter the telescopic tube and the flexible tube, and enter the left fixed frame through the pump on the left side.

[0015] S3: Then the fixed plate moves downward, the fixed plate drives the vertical rod to move downward, the fixed plate drives the elastic plate to compress, the vertical rod drives the movable plate to move downward inside the fixed tube, the coagulant at the top of the movable plate will enter the left fixed frame, the coagulant will come into contact with and mix with the vegetable oil wastewater, thereby coagulating the oil droplets and colloids in the vegetable oil wastewater, improving the removal efficiency of the device.

[0016] S4: The coagulated impurities will float on the surface of the vegetable oil wastewater. When it is necessary to retrieve the coagulated impurities, move the second sealing frame on the left upward. The second sealing frame on the left will drive the second magnetic ring on the left upward, exposing the top opening of the left fixed frame, so that the floating impurities can be retrieved.

[0017] S5: Next, move the U-shaped plate away from the surface of the connecting frame. At the same time, move the U-shaped plate away from the T-shaped plate. Rotate the threaded rod to move the threaded rod away from the connecting plate and the L-shaped plate. Rotate the connecting frame. The connecting frame rotates around the crossbar. Rotate the connecting frame 180 degrees. During the rotation of the connecting frame, the position of the filter plate inside the connecting frame will change. The filter plate will rotate through the hinge. The filter plate will change from its original horizontal state to a vertical state, which means that the connecting frame will no longer filter the vegetable oil wastewater at this time.

[0018] S6: After that, it is not necessary to install the second sealing frame on the left side on top of the left fixed frame. Instead, install the second sealing frame on the right side on top of the left fixed frame. Connect the second connecting cover above to the first connecting cover above the rotating connecting frame. Similarly, the third and fourth magnetic rings are used for installation and connection. The pump above absorbs the vegetable oil wastewater inside the left fixed frame. The vegetable oil wastewater enters the connecting frame through the upper hose and the upper telescopic pipe. After the vegetable oil wastewater enters the connecting frame, a new container will be formed inside the connecting frame, which can then carry out subsequent biological or chemical treatment of the vegetable oil wastewater. The first sealing frames at the top and bottom of the connecting frame can be disassembled for easy use in different situations.

[0019] S7: The fixed frame on the right can store vegetable oil wastewater, which facilitates continuous treatment of vegetable oil wastewater.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention achieves the following through the cooperation between the connecting frame, filter plate, U-shaped plate, and first sealing frame: in the default state, the filter plate is horizontal and can filter vegetable oil wastewater; after rotating the connecting frame, the filter plate is vertical and the connecting frame becomes a container, facilitating subsequent treatment of vegetable oil wastewater; both the upper and lower first sealing frames are detachable, while the threaded rod and U-shaped plate limit the position of the connecting frame.

[0022] Through the cooperation of structures such as the fixed frame, the first connecting cover, the second connecting cover, and the pump, the first connecting cover and the second connecting cover can be connected. The pump can then absorb or discharge vegetable oil wastewater. When the coagulant is poured into the vegetable oil wastewater, the impurities in the wastewater can be coagulated, making it easier to remove the impurities. The positions of the two second sealing covers can be adjusted according to different working conditions. Attached Figure Description

A second annular groove is opened on the side of the first connecting cover 4 away from the connecting frame 2. A fourth magnetic ring 27 is fixedly connected to the second annular groove. A first solenoid valve 10 is provided on the first connecting cover 4.

[0036] In the default state, the filter plate 31 of the connecting frame 2 is horizontal and can filter vegetable oil wastewater. After the connecting frame 2 is rotated, the filter plate 31 is in a vertical state, and the connecting frame 2 becomes a container, which facilitates the subsequent treatment of vegetable oil wastewater. Both the upper and lower first sealing frames 3 have the function of disassembly, while the threaded rod 30 and the U-shaped plate 9 limit the connection frame 2.

[0037] Example 2:

[0038] The conveying mechanism includes two fixed frames 5, which are located on one side of the L-shaped plate 1. The side of the fixed frame 5 closest to the connecting frame 2 is fixedly connected to the adjacent L-shaped plate 1. Each fixed frame 5 has a second sealing frame 6 at its top. A second magnetic ring 8 is fixedly connected to the outer edge of the second sealing frame 6 near its bottom. A first magnetic ring 7 is fixedly connected to the outer edge of the fixed frame 5 near its top. The first magnetic ring 7 and the second magnetic ring 8 are fitted together. Through holes are provided at the top of the left second sealing frame 6 and at the bottom of the right fixed frame 5, and fixed connections are made in the through holes. A connecting pipe 11 is connected to the second solenoid valve 12. A pump 13 is fixedly connected to the bottom of the left fixed frame 5 and the top of the right second sealing frame 6. A hose 14 is fixedly connected to one side of the pump 13. A telescopic pipe 15 is fixedly connected to the end of the hose 14 away from the pump 13. A second connecting cover 16 is fixedly connected to the end of the telescopic pipe 15 away from the hose 14. A first annular groove is opened on the side of the second connecting cover 16 away from the telescopic pipe 15. A third magnetic ring 22 is fixedly connected in the first annular groove.

[0039] Limiting holes are provided at the top of the second sealing frame 6 on the left side, near the four corners. A fixing tube 17 is fixedly connected to each limiting hole. The bottom end of the fixing tube 17 extends into the inner cavity of the fixing frame 5. Four through slots are provided on the outer edge of the fixing tube 17 near the bottom.

The bottom end of each elastic plate 20 is fixedly connected to the top of the second sealing frame 6 on the left side.

[0040] By connecting the first connecting cover 4 and the second connecting cover 16, the pump 13 can absorb or discharge vegetable oil wastewater. When the coagulant is poured into the vegetable oil wastewater, the impurities in the wastewater can be coagulated, making it easier to remove the impurities. The positions of the two second sealing covers 6 can be adjusted according to different working conditions.

[0041] A method for treating wastewater from edible vegetable oil processing includes the following steps:

[0042] S1: When the device starts working, the device has multiple working states. When it is necessary to filter vegetable oil wastewater, the vegetable oil wastewater is first introduced into the connecting frame 2 through the first connecting cover 4 above. The two filter plates 31 inside the connecting frame 2 will filter the impurities in the vegetable oil wastewater.

[0043] S2: Then stretch the second connecting cover 16 on the left side. The second connecting cover 16 on the left side drives the telescopic tube 15 on the left side to stretch. The telescopic tube 15 on the left side drives the flexible tube 14 on the left side to stretch. Connect the second connecting cover 16 on the left side to the first connecting cover 4 below. The second connecting cover 16 on the left side and the first connecting cover 4 below are connected through the third magnetic ring 22 and the fourth magnetic ring 27. Open the first solenoid valve 10 below and start the pump 13 on the left side. The filtered vegetable oil wastewater will enter the telescopic tube 15 and the flexible tube 14 and enter the left fixed frame 5 through the pump 13 on the left side.

[0044] S3: Then the fixed plate 21 moves downward, the fixed plate 21 drives the vertical rod 18 to move downward, the fixed plate 21 drives the elastic plate 20 to compress, the vertical rod 18 drives the movable plate 19 to move downward inside the fixed tube 17, the coagulant at the top of the movable plate 19 will enter the left fixed frame 5, the coagulant will come into contact with and mix with the vegetable oil wastewater, thereby coagulating the oil droplets and colloids in the vegetable oil wastewater, improving the removal efficiency of the device;

[0045] S4: The coagulated impurities will float on the surface of the vegetable oil wastewater. When it is necessary to retrieve the coagulated impurities, move the left second sealing frame 6 upward. The left second sealing frame 6 will drive the left second magnetic ring 8 to move upward, exposing the top opening of the left fixed frame 5, so that the floating impurities can be retrieved.

[0046] S5: Then move the U-shaped plate 9 to remove it from the surface of the connecting frame 2. At the same time, move the U-shaped plate 9 away from the T-shaped plate 23. Rotate the threaded rod 30 to remove it from the connecting plate 29 and the L-shaped plate 1. Rotate the connecting frame 2. The connecting frame 2 rotates around the crossbar 28. Rotate the connecting frame 2 180 degrees. During the rotation of the connecting frame 2, the position of the filter plate 31 inside the connecting frame 2 will change. The filter plate 31 will rotate through the hinge 32. The filter plate 31 will change from the original horizontal state to the vertical state, which means that the connecting frame 2 will no longer filter the vegetable oil wastewater at this time.

[0047] S6: After that, it is not necessary to install the second sealing frame 6 on the left side on top of the fixed frame 5. Instead, install the second sealing frame 6 on the right side on top of the fixed frame 5. Connect the second connecting cover 16 above to the first connecting cover 4 above the rotating connecting frame 2. Similarly, the third magnetic ring 22 and the fourth magnetic ring 27 are used for installation and connection. The pump 13 above absorbs the vegetable oil wastewater inside the fixed frame 5. The vegetable oil wastewater enters the connecting frame 2 through the upper hose 14 and the upper telescopic pipe 15. After the vegetable oil wastewater enters the connecting frame 2, a new container will be formed inside the connecting frame 2, which can then carry out subsequent biological or chemical treatment of the vegetable oil wastewater. The first sealing frame 3 at the top and bottom of the connecting frame 2 can be disassembled for convenient use in different situations.

[0048] S7: The fixed frame 5 on the right can store vegetable oil wastewater, which facilitates continuous treatment of vegetable oil wastewater.

[0049] Working principle: When the device starts working, it has multiple working states. When it is necessary to filter vegetable oil wastewater, the vegetable oil wastewater first enters the connecting frame 2 through the first connecting cover 4 above. The two filter plates 31 inside the connecting frame 2 will filter the impurities in the vegetable oil wastewater. Then, the second connecting cover 16 on the left is stretched. The second connecting cover 16 on the left drives the left telescopic tube 15 to stretch. The left telescopic tube 15 drives the left hose 14 to stretch, connecting the second connecting cover 16 on the left with the first connecting cover 4 below. The second connecting cover 16 on the left and the first connecting cover 4 below are connected by the third magnetic ring 22 and the fourth magnetic ring 27. The first solenoid valve 10 below is opened, and the left pump 13 is started. The filtered vegetable oil wastewater will enter the telescopic tube 15 and the hose 14, and enter the left fixed frame 5 through the left pump 13.

[0050] Then, the fixed plate 21 is moved downward, which drives the vertical rod 18 to move downward. The fixed plate 21 drives the elastic plate 20 to compress. The vertical rod 18 drives the movable plate 19 to move downward inside the fixed tube 17. The coagulant at the top of the movable plate 19 will enter the left fixed frame 5. The coagulant will come into contact with and mix with the vegetable oil wastewater, thereby coagulating the oil droplets and colloids in the vegetable oil wastewater, improving the removal efficiency of the device. The coagulated impurities will float on the surface of the vegetable oil wastewater. When it is necessary to retrieve the coagulated impurities, the left second sealing frame 6 is moved upward. The left second sealing frame 6 drives the left second magnetic ring 8 to move upward, exposing the top opening of the left fixed frame 5, so that the floating impurities can be retrieved.

[0051] Next, move the U-shaped plate 9 away from the surface of the connecting frame 2, simultaneously moving it away from the T-shaped plate 23. Rotate the threaded rod 30, moving it away from the connecting plate 29 and the L-shaped plate 1. Rotate the connecting frame 2, rotating it 180 degrees around the crossbar 28. During this rotation, the position of the filter plate 31 inside the connecting frame 2 changes. The filter plate 31 rotates via the hinge 32, changing from a horizontal to a vertical position. This means that the connecting frame 2 no longer filters the vegetable oil wastewater. After this, it is not necessary to install the left second sealing frame 6 on top of the left fixed frame 5; instead, install the right second sealing frame 6 on top of the left fixed frame 5. The second connecting cover 16 above is connected and installed to the first connecting cover 4 above the rotating connecting frame 2. Similarly, the third magnetic ring 22 and the fourth magnetic ring 27 are used for installation and connection. The pump 13 above absorbs the vegetable oil wastewater inside the left fixed frame 5. The vegetable oil wastewater enters the connecting frame 2 through the upper hose 14 and the upper telescopic pipe 15. After the vegetable oil wastewater enters the connecting frame 2, a new container will be formed inside the connecting frame 2, which can then carry out subsequent biological or chemical treatment of the vegetable oil wastewater. The first sealing frame 3 at the top and bottom of the connecting frame 2 can be disassembled for use in different situations. The fixed frame 5 on the right can store the vegetable oil wastewater for continuous treatment.

Connect the second connecting cover (16) on the left side to the first connecting cover (4) below. The second connecting cover (16) on the left side and the first connecting cover (4) below are connected through the third magnetic ring (22) and the fourth magnetic ring (27). Open the first solenoid valve (10) below and start the pump (13) on the left side. The filtered vegetable oil wastewater will enter the telescopic tube (15) and the hose (14) and enter the left fixed frame (5) through the pump (13) on the left side. S3: Then move the fixed plate (21) downwards. The fixed plate (21) drives the vertical rod (18) to move downwards. The fixed plate (21) drives the elastic plate (20) to compress. The vertical rod (18) drives the movable plate (19) to move downwards inside the fixed tube (17). The coagulant at the top of the movable plate (19) will enter the left fixed frame (5). The coagulant will come into contact with and mix with the vegetable oil wastewater, thereby coagulating the oil droplets and colloids in the vegetable oil wastewater and improving the removal efficiency of the device. S4: The coagulated impurities will float on the surface of the vegetable oil wastewater. When it is necessary to retrieve the coagulated impurities, move the left second sealing frame (6) upward. The left second sealing frame (6) will drive the left second magnetic ring (8) upward, exposing the top opening of the left fixed frame (5), so that the floating impurities can be retrieved. S5: Then move the U-shaped plate (9) first, and move the U-shaped plate (9) away from the surface of the connecting frame (2). At the same time, move the U-shaped plate (9) away from the T-shaped plate (23). Rotate the threaded rod (30) and move the threaded rod (30) away from the connecting plate (29) and the L-shaped plate (1). Rotate the connecting frame (2). The connecting frame (2) rotates around the crossbar (28) as the center. Rotate the connecting frame (2) 180 degrees. During the rotation of the connecting frame (2), the position of the filter plate (31) inside the connecting frame (2) will change. The filter plate (31) will rotate through the hinge (32). The filter plate (31) changes from the original horizontal state to the vertical state, which means that the connecting frame (2) no longer filters the vegetable oil wastewater at this time. S6: After that, it is not necessary to install the second sealing frame (6) on the left side on the top of the fixed frame (5). Install the second sealing frame (6) on the right side on the top of the fixed frame (5). Connect the second connecting cover (16) above to the first connecting cover (4) above the rotating connecting frame (2). Similarly, the third magnetic ring (22) and the fourth magnetic ring (27) are used for installation and connection. The pump (13) above absorbs the vegetable oil wastewater inside the fixed frame (5) on the left side. The vegetable oil wastewater enters the connecting frame (2) through the upper hose (14) and the upper telescopic pipe (15). After the vegetable oil wastewater enters the connecting frame (2), a new container will be formed inside the connecting frame (2), which can then carry out subsequent biological or chemical treatment of the vegetable oil wastewater. The first sealing frame (3) at the top and bottom of the connecting frame (2) can be disassembled for easy use in different situations. S7: The fixed frame (5) on the right side can store vegetable oil wastewater, which facilitates continuous treatment of vegetable oil wastewater.
