[0002] Chemical coatings are a kind of coatable materials that cover the surface of objects, mainly used to protect, beautify and change the surface characteristics of objects. The production and processing of coatings involves multiple steps. During the cleaning process of coating production equipment and pipelines, the cleaning agents and flushing water used may contain residual coatings and solvents, resulting in the generation of wastewater. These generated wastewaters usually contain organic matter, suspended solids, pigment particles and other pollutants. In order to meet the requirements of environmental protection, coating manufacturers need to take corresponding measures to treat and treat wastewater to reduce the impact on the environment. Chemical treatment is one of the most commonly used wastewater treatment methods. This method includes steps such as precipitation, flocculation, neutralization, oxidation and filtration. Through the addition and mixing of chemical agents, suspended matter, sediment and soluble substances in the wastewater can be removed or converted into insoluble substances, thereby achieving the purpose of purifying wastewater.

[0003] When the existing environmental protection treatment device stirs the wastewater generated by chemical coatings, the reagent will cause the suspended matter and sediment in the wastewater to flocculate, and the flocculated substances need to be separated from the water body.

The bottom of the outer side of the two-way screw 7 is threadedly connected with the pressing plate 5, and the pressing plate 5 is slidably connected with the inner wall of the processing box body 1. A sealing ring can be arranged at the bottom of the pressing plate 5 to fill the gap between the pressing plate 5 and the inner wall of the processing box body 1. When the sewage in the processing box body 1 is pressed down, the sewage is not easy to leak upward. A through hole 11 is opened inside the fixing plate 9, and the top of the fixing plate 9 is concave, and the center of the concave part is the through hole 11, so that the sewage on the top of the fixing plate 9 can enter the through hole 11 along the slope. The bottom of the inner side of the through hole 11 is detachably connected with a filter bag 12, and the concave top of the fixing plate 9 facilitates the subsequent sewage to flow into the interior of the filter bag 12 through the through hole 11 along the concave slope.

[0031] Flocculated substances: The sewage and flocculant generated in the process of chemical coating production are fed into the treatment box 1 through the feed pipe 3 on the top of the treatment box cover 2, and then the motor 6 is started, and the motor 6 drives the stirring assembly to rotate, stirring the sewage in the treatment box 1, so that the suspended matter and sediment in the sewage are flocculated;

[0033] Example 2

[0034] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 8The opposite extrusion mechanism includes a first screw sleeve 1301, both sides of the first screw sleeve 1301 are fixedly connected with a first connecting plate 1302, one side of the first connecting plate 1302 is movably connected with a first connecting column 1303, the top of the first connecting column 1303 is provided with a second connecting column 1304, and the top of the second connecting column 1304 is movably connected with a support plate 1305.

[0035] Opposite extrusion: When the bidirectional screw 7 rotates, the pressure plate 5 moves downward to squeeze the water in the sewage through the filter bag 12. At this time, in order to increase the extrusion force on the sewage, the technical solution is provided with a opposite extrusion mechanism. After the bidirectional screw 7 rotates and drives the pressure plate 5 to move downward, the bidirectional screw 7 will also drive the first screw sleeve 1301 to move upward, so that the first screw sleeve 1301 pushes the first connecting column 1303 and the second connecting column 1304 to move upward through the first connecting plate 1302. After the second connecting column 1304 moves, it will push the support plate 1305 to move upward, and the support plate 1305 will push the filter bag 12 to move upward. After moving upward, the filter bag 12 is compressed, so that the sewage in the filter bag 12 is further squeezed and filtered, thereby improving the extrusion efficiency of the filter bag 12.

[0036] See also Figures 1 to 8 A mounting groove 16 is provided on one side of the first connecting column 1303, and a bolt 17 is arranged inside the mounting groove 16. A threaded groove 18 is provided on one side of the second connecting column 1304, and one end of the bolt 17 extends into the inside of the threaded groove 18 and is threadedly connected to the threaded groove 18. There are several threaded grooves 18, and the several threaded grooves 18 are equidistantly distributed.

[0037] Extrusion height adjustment: When the bidirectional screw 7 rotates, the pressure plate 5 and the first screw sleeve 1301 move the same distance. In order to adapt to different pollution conditions of sewage and prevent the flocculants in the filter bag 12 from easily overflowing when the pollution is serious, the technical solution sets the bolt 17 and the thread groove 18 so that the second connecting column 1304 can slide up and down in the first connecting column 1303 to adjust the position. After adjustment, the overall height of the first connecting column 1303 and the second connecting column 1304 can be changed and positioned by the bolt 17 after adjustment. When the overall height of the first connecting column 1303 and the second connecting column 1304 is reduced, the distance between the support plate 1305 and the first screw sleeve 1301 will also be reduced accordingly;

[0038] Furthermore, when the moving distance of the first screw sleeve 1301 remains unchanged, the upward extrusion distance of the support plate 1305 is reduced and the extrusion force on the filter bag 12 is also reduced. Conversely, when the overall height of the first connecting column 1303 and the second connecting column 1304 increases, the extrusion force on the filter bag 12 will increase accordingly.

[0039] Example 3

[0040] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1 to 8 The lateral extrusion mechanism includes a shell 1501, and the number of shells 1501 is several, and the several shells 1501 are distributed in a ring shape and equidistantly on the top of the support plate 1305, and one side of the extrusion cross plate 14 is in contact with the filter bag 12, and a sliding plate 1502 is arranged inside the shell 1501, and the sliding plate 1502 is slidably connected to the inner wall of the shell 1501, and a tension spring 1503 is fixedly connected to one side of the sliding plate 1502, and one end of the tension spring 1503 is fixedly connected to the inner wall of the shell 1501, and the other side of the sliding plate 1502 is fixedly connected to the first connecting plate 1302, and one end of the first connecting plate 1302 is fixedly connected to the extrusion cross plate 14, and one side of the sliding plate 1502 is slidably connected to an arc-shaped push plate 1511, and a connecting shaft 1505 is embedded in the internal eccentric position of the arc-shaped push plate 1511, and the bottom of the connecting shaft 1505 passes through the bottom of the support plate 1305.

[0041] See also Figures 1 to 8 A second screw sleeve 1506 is embedded in the interior of the filter plate 10, and the second screw sleeve 1506 is threadedly matched with the first connecting column 1303. The outer side of the first connecting column 1303 is provided with an external thread used in conjunction with the second screw sleeve 1506. A sleeve 1507 is fixedly connected to the outer side of the second connecting column 1304, and a connecting frame 1508 is fixedly connected to the outer side of the sleeve 1507. A first gear 1509 is fixedly connected to one side of the connecting frame 1508. The outer side of the first gear 1509 is meshedly connected to a second gear 1510, and the second gear 1510 is fixedly connected to the outer side of the connecting shaft 1505.

[0042] Lateral extrusion: When the first connecting column 1303 moves upward to a certain height, the first connecting column 1303 will contact the second screw sleeve 1506. At this time, the first connecting column 1303 will rotate while moving upward, so that the second connecting column 1304 at the top will follow the rotation. After the second connecting column 1304 rotates, it drives the first gear 1509 to rotate through the sleeve 1507 and the connecting frame 1508. The first gear 1509 drives the second gear 1510 to rotate. After the second gear 1510 rotates, it drives the connecting shaft 1505 to rotate. The connecting shaft 1505 will drive the arc-shaped push plate 1511 to rotate.

[0043] Due to the eccentric setting of the connecting shaft 1505 in the arc-shaped push plate 1511, the arc-shaped push plate 1511 can push the sliding plate 1502 to move to one side after it rotates. The sliding plate 1502 pushes the extrusion cross plate 14 to move to one side through the second connecting plate 1504. The number of extrusion cross plates 14 is set to be several and distributed in a ring shape. After the movement of several extrusion cross plates 14, the filter bags 12 placed inside will be squeezed. After the filter bags 12 are squeezed toward each other, the filter bags 12 are further squeezed laterally, so that the filter bags 12 are squeezed in multiple directions, and the moisture in the filter bags 12 is further discharged, thereby improving the solid-liquid separation effect.

[0044] See also Figures 1 to 8 A switch door 19 is hinged on one side of the processing box 1, and a lock body is arranged inside the switch door 19. The lock body fixes the switch door 19 and the processing box 1. A sealing gasket 20 is fixedly connected to one side of the switch door 19, and the sealing gasket 20 is in close contact with the inner wall of the processing box 1.

[0045] By setting the switch door 19 and the sealing gasket 20, the filter bag 12 in the processing box 1 can be removed after the switch door 19 is opened. When removing the filter bag 12, the pins in the first plug board 22 and the second plug board 23 are pulled out. After the pins are pulled out, the filter bag 12 is moved downward and then the filter bag 12 is taken out of the processing box 1, and then the flocculant in the filter bag 12 can be processed. The sealing gasket 20 can prevent liquid from leaking from the gap between the switch door 19 and the processing box 1 when solid-liquid separation is performed in the processing box 1.

[0046] See also Figures 1 to 8 The top of the filter bag 12 is fixedly connected with a fixing frame 21, which can be made of steel, so that the fixing frame 21 can support and fix the filter bag 12. Both sides of the fixing frame 21 are fixedly connected with a first plug-in board 22, and the bottom of the fixing plate 9 is fixedly connected with a second plug-in board 23. The first plug-in board 22 and the second plug-in board 23 are detachably connected by a latch, and the latch can be inserted and removed between the first plug-in board 22 and the second plug-in board 23.

[0047] By setting the fixing frame 21, the first plug-in board 22 and the second plug-in board 23, the plugging and pulling out of the pins in the first plug-in board 22 and the second plug-in board 23 can achieve the effect of installing and disassembling the filter bag 12. After the filter bag 12 filters the flocculated material, it can be disassembled and taken out and the flocculated material inside it can be processed.

[0048] Both ends of the sliding plate 1502 are fixedly connected to the limit blocks 24. The inner wall of the shell 1501 is provided with a limit groove 25 used to cooperate with the limit block 24. The limit block 24 and the limit groove 25 are loosely matched. The length of the limit groove 25 is greater than the length of the limit block 24.

[0049] By providing the limiting block 24 and the limiting groove 25, the movement of the sliding plate 1502 can be restricted when the sliding plate 1502 moves, thereby preventing the sliding plate 1502 from shaking and causing the sliding plate 1502 to get stuck when moving.

[0050] A water inlet 26 is opened inside the pressure plate 5, and a fixing rod 27 is embedded inside the pressure plate 5. The bottom of the fixing rod 27 is slidably connected to an extension rod 28, and the bottom of the extension rod 28 is fixedly connected to a sealing float 29. The sealing float 29 is made of foam and is located at the bottom of the water inlet 26.

[0051] By setting the water inlet 26, the fixed rod 27, the extension rod 28 and the sealing float 29, the extension rod 28 can slide up and down in the fixed rod 27, and then when there is too much sewage in the treatment box 1, the sealing float 29 will be pushed to float up. After the sealing float 29 floats up, the water inlet 26 will be sealed. After sealing, it is convenient for the pressure plate 5 to push the sewage in the treatment box 1 downward through the filter bag 12.

[0052] The stirring assembly includes a fixed seat 8001, and a stirring rod 8002 is fixedly connected to the outer side of the fixed seat 8001. There are a plurality of stirring rods 8002, and the plurality of stirring rods 8002 are equidistantly distributed in a ring shape.

[0053] By setting up a stirring assembly, when the bidirectional screw 7 rotates, it will push the fixed seat 8001 to rotate, and the fixed seat 8001 will push the stirring rod 8002 to rotate. After the stirring rod 8002 rotates, it stirs the sewage in the treatment box 1, causing the suspended matter and sediment in the sewage to flocculate, thereby accelerating the flocculation effect.
