Description

Technical Field

[0002] As one of the most widely used materials in the world, plastic has become an increasingly prominent issue in terms of waste disposal as its production and consumption increase. In order to protect the environment, plastics need to be reused. In the production process of recycled plastic particles, wastewater usually contains various harmful substances, such as dyes, chemical additives, plastic decomposition products, oil and heavy metals. If these wastewaters are discharged directly into the environment without treatment, it will cause water pollution, destroy the ecological balance and affect the quality of water resources. Purification technology is needed to treat the wastewater and reuse it. This will not only reduce the demand for external water resources, but also greatly reduce the consumption of new water. The recycling of water resources in the manufacturing process will help alleviate the increasingly severe problem of water shortage and reduce production costs. Therefore, wastewater purification and reuse equipment can effectively remove these harmful substances and avoid pollution to the environment.

[0003] In the existing wastewater purification, the method is often to pour the agent into the reservoir to degrade and decompose the organic matter, and after physical natural sedimentation, the purified clean wastewater is discharged, thereby achieving the purification and reuse of the wastewater. However, when explaining and decomposing the organic matter in the wastewater, additional equipment is required to oxygenate the wastewater in the reservoir, which increases energy consumption and reduces the overall utilization rate of the equipment. In addition, when cleaning the sludge that naturally settles after the decomposition of the wastewater, a scraper is often used to clean it reciprocatingly. The sludge deposited at the bottom of the reservoir is usually dense and sticky, and the reciprocating scraper method cannot completely remove these sediments adhering to the bottom.

A plurality of through pipes 8 are installed on both sides of the water pump 7, and a door panel 4 is installed at the bottom of the other side of the water reservoir 1. The door panel 4 is located inside the water reservoir 1, and the door panel 4 and the water reservoir 1 are installed in a pull-out manner, and a sealing strip is used to seal the door panel 4 and the water reservoir 1. When the door panel 4 is in When in the closed state, when the wastewater is being purified inside the water reservoir 1, no wastewater leakage will occur inside the water reservoir 1. Cavities 12 are provided on both sides of the top of the water reservoir 1, and second chutes 37 are provided on both sides of the inside of the water reservoir 1. A first chute 11 is provided through the top of the water reservoir 1, and the first chute 11 is connected to the cavity 12. An integrated wastewater purification and cleaning mechanism is provided inside the water reservoir 1, which can fully cover the bottom of the water reservoir 1 to ensure that silt in all areas can be effectively removed. At the same time, the accumulation of silt is avoided to hinder the water flow, thereby improving the effective volume and water flow uniformity of the water reservoir 1 and ensuring the sedimentation and purification effect of the wastewater.

[0038] like Figure 3-Figure 11As shown, the integrated wastewater purification and cleaning mechanism includes two wedge blocks 18, one side of the wedge block 18 is slidably connected to a plurality of first rotating rods 20, the first rotating rod 20 is L-shaped, and the plurality of first rotating rods 20 are symmetrically distributed around the circumference, and the other end of the wedge block 18 is rotatably connected to a connecting plate 13, the connection between the connecting plate 13 and the wedge block 18 is located inside the first chute 11, and the connecting plate 13 is slidably connected to the water reservoir 1, and the synchronous stirring and oxygen supply can ensure the uniform distribution of oxygen in the wastewater, avoiding the uneven oxygen supply that causes oxygen in some areas. The first rotating rod 20 is slidably connected to the first circular plate 21 and the second circular plate 23 at the other end. When the first circular plate 21 and the second circular plate 23 rotate, the second rotating rod 24 is driven to rotate inside the first circular plate 21 and the second circular plate 23. At the same time, the second rotating rod 24 slides back and forth inside the first circular plate 21 and the second circular plate 23. When the cleaning roller 33 encounters different thicknesses of silt in different areas, the first circular plate 21 moves up and down under the action of the support rod 25. At the same time, the connecting frame 27 and its connecting components move up and down synchronously. , and the support rod 25 always remains stationary during the entire movement process and does not rotate. The bottom of the first circular plate 21 is rotatably connected to the support rod 25. The support rod 25 is an L-shaped structure. The support rod 25 and the second rotating rod 24 are located inside the drum 26 away from the second circular plate 23. The inside of the drum 26 is a hollow structure. Two hoses 35 are fixedly connected to the inner wall of the drum 26. One end of the hose 35 is connected to the outside of the drum 26, and the other end of the hose 35 is fixedly connected to the support rod 25. A rotor connecting rod 36 is provided inside the drum 26. The two ends of the sub-connecting rod 36 are respectively fixedly connected to the eccentric points of the two main gears 29. One end of the rotor connecting rod 36 squeezes the hose 35. The end of the support rod 25 away from the second circular plate 23 is located at the center of the main gear 29, and the interior of the support rod 25 is a hollow structure. The support rod 25 is slidably connected to the second circular plate 23. The support rod 25 and the second rotating rod 24 are slidably connected to the rotating plate 28 at one end away from the second circular plate 23. The rotating plate 28 is rotatably connected to the connecting frame 27, and the rotating plate 28 is located inside the connecting frame 27. One side of the rotating plate 28 is rotatably connected to the main gear 29.

[0039] like Figure 3-Figure 12As shown, driven gears 30 are connected to both sides of the bottom of the main gear 29, and the driven gears 30 are rotatably connected to the connecting frame 27. A connecting rod 32 is fixedly connected between each of the driven gears 30. The connecting rod 32 is fixedly connected to a cleaning roller 33. A plurality of brushes 34 are fixedly connected to the outer wall of the cleaning roller 33. The plurality of brushes 34 are symmetrically distributed around the circumference. The plurality of brushes 34 connected to the outer walls of the two cleaning rollers 33 are alternately engaged with each other. An arc-shaped baffle 31 is welded on one side of the connecting frame 27. One end of the arc-shaped baffle 31 is located at the roller The top of the drum 26, and the other end of the arc-shaped baffle 31 is located on the side of the cleaning roller shaft 33. The two main gears 29 are rotatably connected to the drum 26. The support rod 25 and the second rotating rod 24 are away from the end of the second circular plate 23 and are slidably connected with the rotating plate 28 and the main gear 29. When the main gear 29 rotates, the rotor connecting rod 36 rotates synchronously. Due to the relationship between the drum 26 and the main gear 29, when the main gear 29 rotates, it will not drive the drum 26 to rotate. In addition, since the rotor connecting rod 36 is fixed to the eccentric position of the main gear 29, the rotor connecting rod When the rotor connecting rod 36 rotates, one end of the rotor connecting rod 36 will slide and connect with the inner wall of the drum 26, thereby squeezing the hose 35, thereby forming a vacuum inside the hose 35. Under the action of atmospheric pressure, air is forced to enter the hose 35 through the support rod 25. As the rotor connecting rod 36 rotates continuously, air continuously enters the hose 35 and is discharged from the connection port of the drum 26, thereby achieving oxygenation of the wastewater in the water reservoir 1. The first circular plate 21 and the second circular plate 23 are slidably connected with a plurality of second rotating rods 24, and the second rotating rods 2 4 is arranged in an L-shaped structure. In a traditional system, stirring, oxygenation and sludge cleaning may be independently operated by different equipment. This decentralized operation may lead to duplication and waste of energy. The integrated wastewater purification and cleaning mechanism can avoid this problem and improve the overall energy utilization efficiency. The second rotating rod 24 does not intersect with the first rotating rod 20. The second rotating rod 24 and the first rotating rod 20 are arranged in the same shape. The second circular plate 23 is rotatably connected to the support plate 22. The support plate 22 is located inside the second chute 37 and is slidably connected to the water reservoir 1.

[0040] like Figures 1-9The wastewater purification and cleaning integrated mechanism includes two sliding rods 10, which are located inside the cavity 12 and are rotatably connected to the water reservoir 1. Limiting strips 19 are welded on both sides of the outer wall of the sliding rod 10, and the sliding rod 10 and the limiting strip 19 are slidably connected with a second bevel gear 16, and the limiting strip 19 limits the second bevel gear 16, and the second bevel gear 16 is rotatably connected to the connecting plate 13 away from the side of the wedge block 18. The connection between the connecting plate 13 and the second bevel gear 16 is hollow, and the sliding rod 10 and the limiting strip 19 are located at the hollow part of the connecting plate 13. A convex plate 15 is welded on the top of one of the connecting plates 13. Effective stirring can prevent pollutants and solid particles in the wastewater from accumulating at the bottom, reduce sediment formation, and improve the overall purification effect of the water body. The convex plate 15 is threadedly connected with a threaded rod 17. Under the action of the bottom sliding rod 10 and the limiting strip 19, the threaded rod 17 drives the convex plate 15 to move along the linear direction of the threaded rod 17. At the same time, the connecting plate 13 and its connecting components move synchronously, thereby prompting the support plate 22 to slide in the second slide groove 37, and both ends of the threaded rod 17 are rotatably connected to the water reservoir 1. The top of one side of the water reservoir 1 is rotatably connected with a synchronous belt assembly 9. The synchronous belt assembly 9 includes a synchronous belt and a synchronous wheel. The synchronous wheel connecting shaft in the synchronous belt assembly 9 is rotatably connected to the water reservoir 1. The through end of the synchronous wheel connecting shaft in the synchronous belt assembly 9 is fixedly connected to the slide rod 10. The first motor 2 and the second motor 3 are installed on the top of the other side of the water reservoir 1. The output ends of the first motor 2 and the second motor 3 are rotatably connected to the water reservoir 1, and the through end of the first motor 2 is fixedly connected to the slide rod 10, which can accurately clean the sludge and avoid harmful substances in the sludge from entering the water body again, thereby reducing secondary pollution to the water quality. At the same time, the cleaning task can be completed automatically, reducing errors caused by improper human operation or negligence, and improving the reliability of the entire wastewater treatment system.

[0041] like Figure 2-14 As shown, the through end of the second motor 3 is fixedly connected to the threaded rod 17, and one side of the second bevel gear 16 is transmission-connected to the first bevel gear 14. The first bevel gear 14 rotates and synchronously drives the wedge block 18 to rotate. Since the first rotating rods 20 are symmetrically distributed on the circumference, the first rotating rod 20 rotates with the wedge block 18, and the first rotating rod 20 slides cyclically inside the wedge block 18, thereby pushing the first circular plate 21 and the second circular plate 23 at the bottom to rotate, which can effectively reduce the deposition or aggregation of particulate matter in the wastewater, ensure the uniform distribution of suspended matter in the wastewater, avoid local sedimentation affecting the subsequent treatment effect, help the flocculant in the wastewater to fully mix with the suspended matter, enhance the flocculation reaction, promote the aggregation, precipitation and removal of suspended matter, and slide back and forth on the first circular plate 21 and the second circular plate 23, the connecting shaft of the first bevel gear 14 is rotatably connected to the connecting plate 13, and the through end of the connecting shaft of the first bevel gear 14 is fixedly connected to the wedge block 18.

[0042] The working principle of this embodiment is as follows: after pouring wastewater into the water reservoir 1, and then pouring chemicals into the water reservoir 1, the organic matter in the wastewater is promoted to degrade and decompose. While pouring the chemicals, the first motor 2 and the second motor 3 rotate at the same time. The operation of the first motor 2 drives the slide bar 10 and the limit bar 19 to rotate at the same time, so that the second bevel gear 16 rotates and drives the first bevel gear 14 on one side to rotate, prompting the wedge block 18 to rotate synchronously, so that several first rotating rods 20 rotate simultaneously with the wedge block 18 and move back and forth inside the wedge block 18, thereby causing the first circular plate 21 and the second circular plate 23 to rotate synchronously.

[0043] When the first circular plate 21 and the second circular plate 23 rotate, they drive the plurality of second rotating rods 24 to rotate. At the same time, the plurality of second rotating rods 24 slide back and forth inside the first circular plate 21 and the second circular plate 23, while the support rod 25 is in a stationary state and does not rotate. As a result, the other end of the second rotating rod 24 drives the rotating plate 28 and the main gear 29 to rotate. Since the rotating plate 28 and the main gear 29 are respectively connected to the connecting frame 27 for rotation, when the rotating plate 28 and the main gear 29 rotate, the connecting frame 27 does not rotate accordingly, which prompts the rotor connecting rod to rotate. 36 rotates simultaneously with the main gear 29. Since the rotor connecting rod 36 is fixed at the eccentric point with the main gear 29, when the rotor connecting rod 36 rotates, one end of the rotor connecting rod 36 will slide and connect to the inner wall of the drum 26, thereby squeezing the hose 35, thereby forming a vacuum inside the hose 35. Under the action of atmospheric pressure, air is forced to enter the hose 35 through the support rod 25. As the rotor connecting rod 36 continues to rotate, air continues to enter the hose 35 and is discharged from the connection port of the drum 26 to perform an oxygenation process on the wastewater in the water reservoir 1.

[0044] The second motor 3 drives the threaded rod 17 to rotate. Under the action of the convex plate 15, the connecting plate 13 and its components move back and forth inside the water reservoir 1. The first rotating rod 20 and the second rotating rod 24 and other components on both sides of the water reservoir 1 rotate continuously, which can stir the wastewater in the water reservoir 1, help to distribute the dissolved oxygen in the wastewater more evenly, and avoid local oxygen deficiency. At the same time, stirring can promote the full contact between pollutants in the water and oxygen, improve the reaction efficiency, and thus accelerate the removal of organic matter.

[0045] After the equipment stops running for a period of time, the organic matter in the wastewater settles naturally, and the sludge accumulates at the bottom of the reservoir 1. The clean wastewater is located on top of the sludge. The water pump 7 runs to discharge the purified wastewater in the reservoir 1 into the clean water tank 5 through the pipe 8, and then discharged into the river through the drain pipe 6.

[0046] As for the silt accumulated at the bottom of the water reservoir 1, the staff can push and pull the door panel 4 to open the bottom of the water reservoir 1, repeat the above operation steps, the main gear 29 rotates to drive the driven gears 30 on both sides to rotate, and under the action of the connecting rod 32, the cleaning roller 33 rotates, and with the cooperation of the arc baffle 31, the silt moves toward the direction of one door panel 4, so that it is discharged.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
