Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically to a continuous treatment device for refined cotton wastewater. Background Technology

[0002] Wastewater is generated in multiple stages of the refined cotton production process, from cotton linters to finished refined cotton. These include processes such as cooking, bleaching, and washing. For example, cooking produces wastewater containing large amounts of lignin, hemicellulose, pectin, and other substances. Bleaching and acid treatment produce wastewater containing acidic substances such as sulfuric acid and nitric acid, as well as bleach residues. Washing and calcining also generate large amounts of wastewater. If discharged directly, this will cause serious pollution to water bodies, soil, and other environmental elements, threatening the ecological balance and the health of surrounding residents.

[0004] The aforementioned patent describes a continuous treatment device for refined cotton wastewater. This device can continuously and effectively treat refined cotton wastewater, enabling it to meet discharge standards. However, this device only considers wastewater treatment but ignores the possibility of generating toxic and harmful gases during the wastewater treatment process. These gases can cause certain degrees of damage to humans or the environment. Summary of the Invention

[0008] Preferably, the inner wall of the first cylinder is provided with a threaded groove, the first cylinder is threadedly connected to the disc, the ring is rotatably connected to the first cylinder, the output end of the electric telescopic rod moves, the output end of the electric telescopic rod drives the disc to move, when the disc moves upward, the spiral tooth groove of the disc will drive the spiral groove of the first cylinder to rotate, the agent inside the first cylinder moves upward with the disc and is squeezed out through the round rod, while mixing with the waste liquid, the rotation of the round rod driven by the first cylinder can also play a stirring role.

[0009] Preferably, one-way valves are installed inside pipe 1, pipe 2, pipe 3 and the drain hole. The end of pipe 3 away from the purification device is fixedly connected to a circular ring. The air inside cylinder 1 is squeezed out, the atmospheric pressure decreases, and the atmospheric pressure inside the reaction tank increases. At the same time, the reagent and waste liquid will produce gas after mixing. The gas in the reaction tank is discharged into the purification device through pipe 3. After being purified by the purification device, the gas is discharged through pipe 2, reducing pollution.

[0010] Preferably, the filter press further includes a grid plate, which is fixedly installed on the conveying mechanism. A rotating shaft is rotatably installed on the side of the grid plate, and a baffle is fixedly installed on the side of the rotating shaft. A spring is provided between the baffle and the grid plate.

A torsion spring is provided between the rotating shaft and the stop bar. A stop block is fixedly installed on the side of the box. A collection box is provided at the bottom of the box. Wastewater flows down the conveying mechanism. During the downward flow, the conveying mechanism moves the grid plate. The lint or large particulate impurities in the wastewater are filtered by the grid plate, and the liquid flows down normally.

[0011] Preferably, the baffle plate has a groove, and a spring is disposed inside the groove. Six baffle plates are provided, and the six baffle plates are evenly distributed on the surface of the conveying mechanism. When the baffle plate rotates downward with the conveying mechanism, the baffle plate no longer contacts the baffle plate, and the baffle plate returns to its original position due to the spring force. Impurities on the baffle plate will fall into the collection box below.

[0012] Preferably, the stirring device further includes a sedimentation tank, which is fixedly installed on the side of the housing 1. A storage tank is fixedly installed on the side of the sedimentation tank, and a pipe 4 is connected to the side of the storage tank. A rotating shaft 3 is rotatably installed on the inner wall of the sedimentation tank. A gear 1 is fixedly installed on the circumference of the rotating shaft 3. A cylinder 2 is fixedly installed on the circumference of the rotating shaft 3. A baffle is fixedly installed on the circumference of the cylinder 2.

A gear 2 is fixedly installed on the rotating shaft 4. A stirring rod is fixedly installed at the end of the rotating shaft 4 away from the gear 2. Wastewater flows into the sedimentation tank through a conveying mechanism. When the wastewater flows down, it impacts the baffle.

There are three stirring rods evenly distributed on the circumferential surface of the fourth rotating shaft. Gear one drives gear two to rotate, gear two drives the fourth rotating shaft to rotate, and the fourth rotating shaft drives the stirring rods to rotate, thereby stirring the wastewater inside the sedimentation tank to fully mix it and achieve rapid separation.

[0015] This invention provides a continuous treatment device for refined cotton wastewater. It has the following beneficial effects: (1) This continuous treatment device for refined cotton wastewater utilizes centrifugal force and stirring to rapidly and uniformly mix the reagents and wastewater, significantly improving reaction efficiency. The design of an electric telescopic rod driving the cylinder to reciprocate rotate automatically discharges the reagent tank using pressure changes, reducing manual intervention and ensuring continuous supply. The gas generated during the reaction is treated by a purification device before being discharged, effectively reducing the risk of environmental pollution. Utilizing the principle of communicating vessels, the liquid automatically flows into the next device when it reaches a set height, achieving automated process connection. This saves energy and avoids human error. The overall structure balances reaction efficiency, environmental protection requirements, and automated control, demonstrating strong practicality and innovation.

[0016] (2) This continuous treatment device for refined cotton wastewater uses a filter press to move a grid plate via a conveying mechanism, achieving dynamic separation of wastewater from large particulate impurities such as cotton fibers. During the movement of the grid plate, the baffle is squeezed, and the impurities are pressed by the reaction force of the spring, thus improving the solid-liquid separation efficiency. When the grid plate rotates to the bottom, the impurities fall into the collection box due to gravity, and at the same time, the baffle rod slides and scrapes the surface of the grid plate under the action of the torsion spring, thoroughly removing residual impurities and preventing filter screen blockage. The device integrates the functions of filtration, pressing, and scraping into the operation of the conveying mechanism, and achieves automated continuous operation through the linkage between mechanical structures, reducing the frequency of manual cleaning, improving wastewater treatment efficiency, and reducing operation and maintenance costs. The structure is compact and highly practical.

[0017] (3) The continuous treatment device for refined cotton wastewater uses the kinetic energy of the wastewater flow to impact the baffles, converting the kinetic energy of the water flow into mechanical power to drive the cylinder, rotating shaft and gear set to operate. It can achieve automatic addition of flocculant and stirring of wastewater without additional energy. The design of six baffles and grid plates in staggered contact ensures uninterrupted power transmission. When gear one rotates, the through hole accurately connects to the pipeline to achieve quantitative addition of flocculant. At the same time, gear two drives the stirring rod to continuously stir the wastewater, promote the full integration of the agent and the wastewater, and accelerate the coagulation and sedimentation of impurities. The device uses the water flow power linkage mechanical structure to recover and utilize the kinetic energy in the agent addition and stirring process, which not only reduces energy consumption, but also improves sedimentation efficiency through the automated process, achieving the dual advantages of energy saving and high-efficiency treatment.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 One embodiment of the present invention is: a continuous treatment device for refined cotton wastewater, including a box 1, a side panel 2 fixedly installed on the side of the box 1, a conveying mechanism 3 arranged in the middle of the side panel 2, and also including a feeding device, a filter press device and a stirring device. The feeding device further includes a reaction tank 4, with a cross plate 5 fixedly installed below the reaction tank 4 and an electric telescopic rod 6 fixedly installed above the cross plate 5. A reagent tank 7 is fixedly installed on the side of the reaction tank 4, and a pipe 8 connects the reagent tank 7 to the reaction tank 4. A purification device 9 is installed on the top of the reaction tank 4, with a pipe 10 connected to the side of the purification device 9 and a pipe 11 connected to the bottom of the purification device 9. A U-shaped pipe 12 connects to the side of the reaction tank 4. A cylinder 13 is rotatably installed at the bottom of the inner wall of the reaction tank 4. A disc 14 is fixedly installed at the output end of the electric telescopic rod 6. A circular rod 141 is fixedly installed on the circumference of the cylinder 13. A circular ring 15 is fixedly installed on the top of the inner wall of the reaction tank 4. The circular rod 141 has a drain hole inside, so that wastewater can be poured into the reaction tank 4. The reagent tank 7 transports the reagent into the cylinder 13 through the pipe 8. The electric telescopic rod 6 is activated, and the output end of the electric telescopic rod 6 moves. The output end of the electric telescopic rod 6 drives the disc 14 to move. When the disc 14 moves upward, the spiral groove of the disc 14 will drive the spiral groove of the cylinder 13 to rotate, and the cylinder 13 will also rotate. This device uses the dual action of centrifugal force and stirring to make the reagent and wastewater mix quickly and evenly, which significantly improves the reaction efficiency. The inner wall of cylinder 13 is provided with a threaded groove. Cylinder 13 is threadedly connected to disc 14. The ring 15 is rotatably connected to cylinder 13. The medicine inside cylinder 13 moves upward with disc 14 and is discharged through the drain hole of rod 141. While mixing with waste liquid, cylinder 13 drives rod 141 to rotate, which also plays a stirring role. The design of electric telescopic rod 6 driving cylinder to reciprocate is used to realize automatic feeding of medicine tank 7 by means of pressure change, reducing manual intervention and ensuring continuous feeding.

[0022] One-way valves are installed inside pipe 1 (8), pipe 2 (10), pipe 3 (11), and round rod 141. The end of pipe 1 (8) away from the reagent tank 7 is fixedly inserted through the ring 15. The end of pipe 3 (11) away from the purification device 9 is fixedly inserted through the inside of the reaction tank 4. The one-way valves can effectively prevent liquid backflow. At the same time, gas will be generated after the reagent and waste liquid are mixed. The gas in the reaction tank 4 is discharged into the purification device 9 through pipe 3 (11). After being purified by the purification device 9, the gas is discharged through pipe 2 (10), reducing pollution. The gas generated by the reaction is treated by the purification device 9 before being discharged, effectively reducing the risk of environmental pollution.

[0023] In this embodiment, during operation: wastewater is poured into reaction tank 4 via the feeding device. The reagent tank 7 delivers the reagent to cylinder 13 via pipe 8. The electric telescopic rod 6 is activated, causing its output end to move. This movement drives the disc 14 to move. As the disc 14 moves upward, its helical grooves rotate the helical grooves of cylinder 13, causing cylinder 13 to rotate as well. This reduces the internal pressure of cylinder 13. The ring 15 on the bottom surface of reaction tank 4 restricts the cylinder's rotation, causing it to rotate within the ring 15. The reagent inside cylinder 13 is discharged through the drain hole of the rod 141 as the disc 14 moves upward, mixing with the wastewater. Simultaneously, cylinder 13 drives the helical grooves of cylinder 13 to rotate. The rotation of rod 141 also serves as a stirrer. When disc 14 presses the top of the guide, the air inside cylinder 13 is squeezed out, reducing atmospheric pressure and increasing atmospheric pressure inside reaction tank 4. At the same time, the mixture of reagent and waste liquid produces gas. The gas in reaction tank 4 is discharged into purification device 9 through pipe 3 11. After purification by purification device 9, the gas is discharged through pipe 2 10, reducing pollution. When the electric telescopic rod 6 retracts, the pressure inside cylinder 13 increases, and the atmospheric pressure promotes the discharge of reagent tank 7. At this time, cylinder 13 rotates in the opposite direction. The retraction of electric telescopic rod 6 enables the cylinder to rotate back and forth. When the liquid level in reaction tank 4 reaches the height of U-tube 12, the wastewater is discharged through U-tube 12.

[0024] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the filter press further includes a grid plate 16, which is fixedly mounted on the conveying mechanism 3. A rotating shaft 17 is rotatably mounted on the side of the guardrail 2, and a baffle 18 is fixedly mounted on the side of the rotating shaft 17. A spring 19 is provided between the baffle 18 and the guardrail 2. A rotating shaft 20 is fixedly mounted on the side of the housing 1, and a stop bar 21 is fixedly mounted on the side of the rotating shaft 20. A torsion spring 22 is provided between the rotating shaft 20 and the stop bar 21. A baffle 23 is fixedly installed on the surface, and a collection box 24 is set at the bottom of the box 1. Wastewater flows down along the conveying mechanism 3. During the downward flow, the conveying mechanism 3 moves the grid plate 16. The cotton fibers or large particles in the wastewater are filtered by the grid plate 16. The liquid flows down normally. The filter press device moves the grid plate 16 through the conveying mechanism 3 to realize the dynamic separation of wastewater and large particles such as cotton fibers. During the movement of the grid plate 16, the baffle 18 is squeezed. With the help of the reaction force of the spring 19, the impurities and water are squeezed out, thereby improving the solid-liquid separation efficiency. The baffle plate 2 has a semi-circular groove, and six grid plates 16 are provided, which are evenly distributed on the surface of the conveying mechanism 3. When the grid plates 16 rotate downward with the conveying mechanism 3, the grid plates 16 no longer contact the baffle 18. The baffle 18 is reset by the spring force of the spring 19, and the impurities on the grid plates 16 will fall into the collection box 24 below. The device integrates the functions of filtration, pressing and scraping into the operation of the conveying mechanism 3. It realizes automated continuous operation through the linkage between mechanical structures, reduces the frequency of manual cleaning, improves wastewater treatment efficiency and reduces operation and maintenance costs. The structure is compact and highly practical.

[0025] The stirring device also includes a sedimentation tank 25, which is fixedly installed on the side of the housing 1. A storage tank 26 is fixedly installed on the side of the sedimentation tank 25, and a pipe 27 is connected to the side of the storage tank 26. A rotating shaft 28 is rotatably installed on the inner wall of the sedimentation tank 25. A gear 29 is installed through the circumference of the rotating shaft 28. A cylinder 30 is installed through the circumference of the rotating shaft 28. A baffle 31 is fixedly installed on the circumference of the cylinder 30. A short rod 32 is fixedly installed on the inner wall of the sedimentation tank 25. A rotating shaft 33 is rotatably installed at the end of the short rod 32 away from the sedimentation tank 25. A gear 34 is fixedly installed on the rotating shaft 33. A stirring rod 35 is fixedly installed at the end of gear 33 away from gear 34. Wastewater flows into sedimentation tank 25 through conveying mechanism 3. When the wastewater flows down, it will impact the baffle 31. The baffle 31 rotates, which drives cylinder 30 to rotate. Cylinder 30 drives rotating shaft 28 to rotate. The kinetic energy of water is converted into the rotation of rotating shaft 28 to provide power. With six baffles 31, the power transmission of water flow can be achieved without interruption. This stirring device uses the kinetic energy of wastewater flow to impact the baffles 31, converting the kinetic energy of water flow into mechanical power to drive cylinder, rotating shaft and gear set to operate. Automatic addition of flocculant and stirring of wastewater can be achieved without additional energy. Gear 1 29 has two through holes of the same size as pipe 4 27. Gear 1 29 meshes with gear 2 34. Gear 1 29 drives the through holes on its surface to rotate. When the through holes rotate to the same position as pipe 4 27, the flocculant inside storage tank 26 falls through pipe 4 27. The design of six baffles 31 and grid plate 16 in staggered contact ensures uninterrupted power transmission, so that the through holes of gear 1 29 accurately connect with the pipe when it rotates, realizing the quantitative delivery of flocculant. At the same time, gear 2 34 drives the stirring rod 35 to continuously stir the wastewater, promote the full integration of the agent and wastewater, and accelerate the coagulation and sedimentation of impurities.

[0026] There are six baffles 31, which are evenly distributed on the circumference of the second cylinder 30. The baffles 31 and the grid plate 16 are staggered and can contact each other. There are three stirring rods 35, which are evenly distributed on the circumference of the fourth rotating shaft 33. The first gear 29 drives the meshing gear 34 to rotate, the second gear 34 drives the fourth rotating shaft 33 to rotate, and the fourth rotating shaft 33 drives the stirring rods 35 to rotate, stirring the wastewater inside the sedimentation tank 25, so that it can be fully mixed and achieve rapid separation. The device uses a water flow dynamic linkage mechanical structure to recover and utilize kinetic energy in the reagent addition and stirring process, which not only reduces energy consumption, but also improves sedimentation efficiency through automation, achieving the dual advantages of energy saving and high-efficiency treatment.

[0027] In this embodiment, during operation: In the filter press device, wastewater is conveyed to the conveying mechanism 3 through the U-shaped pipe 12. The wastewater flows downward along the conveying mechanism 3. During the downward flow, the conveying mechanism 3 moves the grid plate 16. Fluff or large particles in the wastewater are filtered by the grid plate 16. The liquid flows downward normally. As the grid plate 16 carries the impurities and gradually moves upward, it squeezes the baffle 18. During the squeezing process, excess water is squeezed out of the impurities. The baffle 18, under the pressure of the grid plate 16, rotates along the rotating shaft 17. The slider of the baffle 18 squeezes the spring 19. The deformation of the spring 19 generates a counterforce, which makes the squeezing between the baffle 18 and the grid plate 16 more thorough. When the grid plate 16 rotates downward with the conveying mechanism 3, the grid... When the grid plate 16 and the baffle plate 18 are no longer in contact, the baffle plate 18 returns to its original position due to the elastic force of the spring 19. Impurities on the grid plate 16 will fall into the collection box 24 below. The grid plate 16 continues to move. At this time, the grid plate 16 touches the baffle bar 21. As the grid plate 16 moves, the baffle bar 21 is pushed and slides on the surface of the grid plate 16, scraping off the impurities that have not fallen off the surface of the grid plate 16. The baffle bar 21 rotates with the rotating shaft 20. The rotation of the rotating shaft 20 will cause the torsion spring 22 to rotate. The torsion spring 22 generates a force in the opposite direction. When the grid plate 16 is no longer in contact with the baffle bar 21, the baffle bar 21 returns to its original position. The baffle bar 21 stops rotating when it reaches the position of the stop block 23. The wastewater is cleaned and impurities are scraped off through the conveying mechanism 3, which further improves the efficiency.

[0028] In this embodiment, during operation: In the stirring device, wastewater flows into the sedimentation tank 25 through the conveying mechanism 3. As the wastewater flows down, it impacts the baffles 31. The rotation of the baffles 31 drives the rotation of the second cylinder 30, which in turn drives the rotation shaft 28. The kinetic energy of the water is converted into the rotation of the third shaft 28, providing power. The presence of six baffles 31 ensures uninterrupted power transmission of the water flow. Simultaneously, the staggered contact between the grid plate 16 and the baffles 31 also provides power for the rotation of the third shaft 28. The third shaft 28 drives the first gear 29 to rotate, which in turn drives the through hole on the surface to rotate. When the through hole rotates to the same position as the fourth pipe 27, the flocculant inside the storage tank 26 falls through the fourth pipe 27. The first gear 29 drives the meshing gear 34 to rotate, which in turn drives the rotation shaft 33 to rotate. The fourth shaft 33 drives the stirring rod 35 to rotate, stirring the wastewater inside the sedimentation tank 25 to achieve rapid separation.
