[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] See also Figures 1 to 6 As shown, a plastic production wastewater environmental protection treatment equipment includes a treatment box 1, a water inlet pipe 14 is fixedly installed on one side of the treatment box 1, a first partition 32 and a third partition 33 are fixedly installed in the inner cavity of the treatment box 1, and two electronic valves 321 are fixedly installed on the bottom of the first partition 32; it also includes a solid cleaning mechanism for cleaning solids in the wastewater; the solid cleaning mechanism includes a first push plate 22, the first push plate 22 is slidably installed in the inner cavity of the treatment box 1, the first partition 32 and the inner wall of the treatment box 1 are slidably installed with a foam filter plate 2, a mud collecting box 322 is fixedly installed at the bottom of the treatment box 1, and a first medicine box 315 is fixedly installed on the top of the treatment box 1, a mud suction pipe 36 is fixedly installed between the first partition 32 and the third partition 33, one end of the mud suction pipe 36 is fixedly connected to a mud suction pump 361, and one side of the mud suction pump 361 is fixedly connected to a mud outlet pipe 362.

[0025] Existing wastewater treatment devices only consider the processing speed when treating wastewater. However, in actual use, the wastewater contains impurities of different volumes, and the impurities in the wastewater are easily aggregated in the wastewater treatment tank. The aggregated impurities are difficult to treat in the treatment tank.

[0026] When the present invention is in use, sewage is first input into the inner cavity of the treatment box 1 through the water inlet pipe 14, and the sewage enters between the first partition plate 32 and the inner wall of the treatment box 1. Then the sewage passes through the foam filter plate 2 and enters the bottom of the foam filter plate 2, while the impurities in the sewage will remain on the top of the foam filter plate 2. As the amount of sewage entering the inner cavity of the treatment box 1 increases, the foam filter plate 2 will also float up under the buoyancy of the sewage. When the top of the foam filter plate 2 floats to the same height as the bottom of the first push plate 22, the water is stopped from being discharged into the inner cavity of the treatment box 1. At this time, the first push plate 22 slides in the inner cavity of the treatment box 1, and the first push plate 22 can push the foam filter plate 2, and eventually push the impurities out of the treatment box 1. In the process of feeding water into the inner cavity of the treatment box 1, due to the balance of liquid pressure, the sewage will pass through the one-way valve 321 and enter between the first partition 32 and the third partition 33. At this time, the first medicine box 315 adds a medicine that can precipitate impurities in the sewage into the sewage. After the impurities in the sewage are precipitated, they will settle into the inner cavity of the mud collecting box 322. At this time, the mud suction pump 361 can be started to discharge the precipitated impurities through the mud discharge pipe 362 through the mud suction pipe 36, thereby achieving the removal of impurities in the sewage and avoiding the problem of disorderly accumulation of sewage in the inner cavity of the treatment box 1.

[0027] Further, such as Figure 2 As shown, two support rods 11 are fixedly installed in the inner cavity of the processing box 1, and two first grooves 12 and a second groove 13 are provided on the inner wall of the processing box 1. The foam filter plate 2 is slidably installed on the inner surfaces of the two first grooves 12. The inner walls of the first grooves 12 are fixedly installed with a sensor 21 and a first limiting rod 121, and the first limiting rod 121 is slidably connected to the foam filter plate 2; Two second limiting rods 271 are fixedly installed in the inner cavity of the processing box 1, and the first push plate 22 is slidably installed on the inner surface of the second groove 13. A threaded rod 25 is rotatably installed in the inner cavity of the processing box 1, and the threaded rod 25 is threadedly connected to the first push plate 22. One end of the threaded rod 25 is fixedly connected to the first motor 24, and the first motor 24 is fixedly installed on the outer surface of the processing box 1; A cleaning bucket 23 is fixedly installed on one side of the first push plate 22, and a plurality of brushes are fixedly installed in the inner cavity of the cleaning bucket 23. The two second limiting rods 271 and the threaded rod 25 are slidably connected to the second push plate 27. Two first springs 272 are fixedly installed on one side of the second push plate 27. The two first springs 272 are respectively wound and installed on the outer surfaces of the two second limiting rods 271. Two push rods 274 are fixedly installed on the other side of the second push plate 27, and a discharge block 273 is fixedly installed on one side of the processing box 1.

[0028] When the present invention is in use, when there is no sewage in the inner cavity of the treatment box 1, the foam filter plate 2 is at the top of the support rod 11. As sewage enters, the sewage will lift the foam filter plate 2, and the two first limiting rods 121 will limit the foam filter plate 2 to prevent the foam filter plate 2 from tilting during the floating process. The floating foam filter plate 2 will touch the sensor 21. Here, a sensor with a control function is selected. Further, the sensor 21 controls the first motor 24 to start, and the output shaft of the first motor 24 rotates with the threaded rod 25. Under the limit of the two second limiting rods 271, the threaded rod 25 drives the first push plate 22 to slide, The cleaning bucket 23 and the brush can prevent impurities in the sewage from affecting the threaded rod 25 to drive the first push plate 22. The first push plate 22 slides on the top of the foam filter plate 2 and pushes the impurities on the top of the foam filter plate 2 to move. Then the first push plate 22 will touch the push rod 274, and then the push rod 274 will move with the second push plate 27. The second push plate 27 can reduce the diffusion of odor in the sewage. After the impurities are discharged through the discharge block 273, the first push plate 22 returns to its initial position, and the second push plate 27 also returns to its initial position under the action of the first spring 272 to continue to prevent the odor from spreading in the inner cavity of the treatment box 1.

[0029] Further, such as Figure 3 As shown, a fan blade 3 is rotatably installed in the inner cavity of the water inlet pipe 14, and a rotating shaft 31 is fixedly connected to one side of the fan blade 3. The rotating shaft 31 is rotatably installed on one side of the first partition 32. One end of the rotating shaft 31 is fixedly connected to a disc 311, and the outer surface of the disc 311 is slidably connected to a T-shaped rod 312. The outer surface of the T-shaped rod 312 is wrapped with a second spring 313. The T-shaped rod 312 is slidably installed on one side of the first partition 32, and one end of the T-shaped rod 312 is fixedly connected to a right-angle baffle 314. The bottom of the first medicine box 315 passes through the inner cavity of the treatment box 1.

[0030] When the present invention is in use, as sewage enters the inner cavity of the treatment box 1 through the water inlet pipe 14, the sewage will impact the fan blades 3, causing the fan blades 3 to rotate, and the fan blades 3 will rotate with the rotating shaft 31 and the disk 311, and the connection between the sensor 21 and the disk 311 is not at the center of the disk 311. Therefore, when the disk 311 rotates, the second spring 313 will be squeezed by the T-shaped rod 312, and the T-shaped rod 312 will move with the right-angle baffle 314. The squeezed second spring 313 will push the T-shaped rod 312 when it is extended. This will enable the right-angle baffle 314 to intermittently block the hole of the first medicine box 315 connecting to the inner cavity of the treatment box 1, thereby allowing the medicine in the first medicine box 315 to contact with the sewage in a controlled manner, avoiding waste caused by excessive dosage of medicine.

[0031] Further, such as Figure 5 As shown, the cleaning box 4 is fixedly connected to one side of the processing box 1, and the inner cavity of the processing box 1 and the inner cavity of the cleaning box 4 are both rotatably installed with stirring rods 34, and the tops of the two stirring rods 34 located between the first partition 32 and the third partition 33 are fixedly connected to the first pulley 342, and the two first pulleys 342 are driven by belts 344, and the top of one of the first pulleys 342 is fixedly connected to the second motor 341, and the second motor 341 is fixedly installed on the top of the processing box 1, and the bottom of one of the first pulleys 342 and the tops of the other two stirring rods 34 are respectively fixedly connected to the second pulleys 343, and the four second pulleys 343 are divided into two groups of two, and the two second pulleys 343 in the same group are driven by belts 344.

[0032] When the present invention is in use, the output shaft of the second motor 341 drives the first pulley 342 and the second pulley 343 to rotate, and the belt 344 transmits the transmission, which can drive several stirring rods 34 respectively. The rotation of the stirring rods 34 can accelerate the mixing when the medicine in the inner cavity of the first medicine box 315 is mixed with the sewage between the first partition 32 and the third partition 33.

[0033] Further, such as Figure 4 and Figure 5 As shown, a second partition 323 is fixedly installed on the top of the mud collecting box 322, and first water pipes 35 are fixedly installed on both sides of the third partition 33. One end of the two first water pipes 35 is fixedly connected to a first water pump 351, and the first water pump 351 is fixedly installed on one side of the processing box 1.

[0034] When the present invention is in use, in order to prevent the precipitated impurities from clogging the one-way valve 321, the impurities close to the one-way valve 321 can be reduced through the second partition 323. After the impurities in the sewage are precipitated, the sewage between the first partition 32 and the third partition 33 can be transferred to between the third partition 33 and the inner wall of the treatment box 1 through the first water pump 351.

[0035] Further, such as Figure 4 and Figure 5 As shown, a water spray pipe 37 is fixedly installed in the inner cavity of the treatment box 1, one end of the water spray pipe 37 is fixedly connected to a second water pump 371, one side of the second water pump 371 is fixedly connected to a second water pipe 372, one end of the second water pipe 372 is fixedly installed in the inner cavity of the cleaning box 4, and a disinfectant tank 38 is fixedly installed on the top of the treatment box 1, and the disinfectant tank 38 is connected to the inner cavity of the treatment box 1; A third water pipe 41 is fixedly installed in the inner cavity of the processing box 1 and the cleaning box 4. One end of the two third water pipes 41 is fixedly connected to a third water pump 42. The third water pump 42 is fixedly installed on one side of the cleaning box 4.

[0036] When the present invention is in use, after the sewage enters between the third partition 33 and the inner wall of the treatment box 1, disinfectant is added to the sewage through the disinfectant tank 38, and the stirring rod 34 is rotated to accelerate the mixing of the disinfectant and the sewage. After the disinfection is completed, the sewage is pumped out to the inner cavity of the cleaning box 4 through the third water pump 42 and the third water pipe 41. In the process of mixing the sewage and the disinfectant, foam will be generated. By pumping out the sewage in the inner cavity of the cleaning box 4 and spraying it out through the water spray pipe 37, the foam on the top of the sewage can be eliminated.

[0037] Further, such as Figure 6 As shown, an activated carbon box 45 is slidably installed in the inner cavity of the cleaning box 4, and two L-shaped connecting rods 44 are fixedly installed on the top of the activated carbon box 45. The bottom of the L-shaped connecting rod 44 is fixedly connected to an electric telescopic rod 43, and the electric telescopic rod 43 is fixedly installed on one side of the cleaning box 4. A drainage outlet is opened on one side of the cleaning box 4.

[0038] When the present invention is in use, after the sewage enters the inner cavity of the cleaning box 4, the activated carbon in the activated carbon box 45 in the inner cavity of the cleaning box 4 can absorb the odor in the sewage. After a period of use, the activated carbon needs to be replaced. The output end of the electric telescopic rod 43 is lifted with the L-shaped connecting rod 44, so that the L-shaped connecting rod 44 can move the activated carbon box 45 out of the inner cavity of the cleaning box 4, which can facilitate the staff to replace the activated carbon. At the same time, the rotation of the stirring rod 34 in the inner cavity of the cleaning box 4 can accelerate the flow of sewage and improve the adsorption efficiency of the activated carbon.

[0039] Working principle: First, sewage is input into the inner cavity of the treatment box 1 through the water inlet pipe 14. The sewage flows into the bottom of the foam filter plate 2 through the foam filter plate 2 and lifts the foam filter plate 2. The impurities in the sewage will remain on the top of the foam filter plate 2. As the sewage increases, the water level will also rise. Finally, when the top of the foam filter plate 2 and the bottom of the first push plate 22 are at the same height, the top of the foam filter plate 2 will also touch the sensor 21. At this time, the sensor 21 controls the first motor 24 to start, and the output shaft of the first motor 24 rotates with the threaded rod 25. The threaded rod 25 cooperates to drive the second limit rod 271 to make the first push plate 22 move along The first push plate 22 slides along the top of the foam filter plate 2, and at the same time, the impurities on the top of the foam filter plate 2 are brought to the discharge block 273 for discharge. The sewage passes through the one-way valve 321 and enters between the first partition plate 32 and the third partition plate 33. The first medicine box 315 adds medicine into the sewage to precipitate the impurities in the sewage. The rotation of the stirring rod 34 in the sewage can accelerate the mixing of the medicine and the sewage, thereby accelerating the precipitation of impurities. After the precipitated impurities are settled in the mud collecting box 322, the mud suction pump 361 cooperates with the mud suction pipe 36 to suck out the impurities in the inner cavity of the mud collecting box 322 and discharge them through the mud discharge pipe 362.

[0040] Then, the sewage with precipitated impurities is pumped out into the cavity between the third partition 33 and the inner wall of the treatment box 1 through the first water pump 351, and then disinfectant is added to the sewage through the disinfectant tank 38. The stirring rod 34 is stuck in the sewage and rotated to further accelerate the disinfection of the sewage. Then, the disinfected sewage is discharged into the inner cavity of the cleaning box 4 through the third water pump 42, and the odor in the sewage is adsorbed by activated carbon. In order to remove the foam generated in the disinfection chamber, the sewage in the inner cavity of the cleaning box 4 is pumped out by the second water pump 371 and sprayed out through the water pipe 37 to eliminate the foam.
