Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for rinsing during the preparation of chenodeoxycholic acid. Background Technology

[0002] By using genetically engineered microorganisms (such as Escherichia coli and yeast), inexpensive substrates (such as cholesterol and phytosterols) can be converted into chenodeoxycholic acid through heterologous expression of steroidal converting enzyme systems.

[0003] In the prior art, patent number CN106904680B, entitled "A Dissolved Air Flotation Machine," includes a dissolved air flotation tank, a sludge scraping device, a release device, a bubble generator, a motor, an outlet pipe, and a dissolved air system. The bubble generator is a tubular structure extending along the length of the dissolved air flotation tank. It is installed inside the release device, with one end connected to a motor installed on the outside of the tank. The motor drives the bubble generator to rotate axially inside the release device, allowing the dissolved air water, wastewater, and flocculant to fully rotate and contact, forming a flocculent mixture. This significantly reduces the residence time during the coagulation-flocculation process, improves treatment efficiency, and eliminates the need for a separate flocculation tank, reducing the footprint of the dissolved air flotation machine and making it more compact. Furthermore, the release device releases the mixture into the entire dissolved air flotation tank for contact and separation reactions, demonstrating a strong ability to handle fluctuations in water flow.

[0004] In the process of preparing deoxycholic acid, the wastewater first needs to be treated by an air flotation machine to remove grease and suspended pollutants. The microbubbles generated by the air flotation can quickly adsorb the scum formed by the pollutants. However, during the process of pushing the scum through the scum removal plate, some particles can easily adhere to the surface of the scum removal plate. When the scum removal plate rotates back into the water, the particles will fall back into the water, which reduces the efficiency of particle removal. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 10 The present invention provides a technical solution: Example 1: A wastewater treatment device for rinsing during the preparation of chenodeoxycholic acid, comprising: a treatment tank 1, wherein a reaction tank 8, a scum tank 9, and a purified water tank 10 are arranged inside the treatment tank 1; an air inlet pipe 2 and a vertical pipe 4 are arranged inside the treatment tank 1; an arc-shaped plate 27 and a groove 28 are fixed inside the treatment tank 1; a fixing block 11 is fixed on the surface of the treatment tank 1; a rotating shaft 12 is arranged on the surface of the fixing block 11; a conveyor belt 13 is arranged on the surface of the rotating shaft 12; a fixing plate 17 is fixed on the surface of the conveyor belt 13; a first scum plate 15 is arranged at one end of the fixing plate 17; a float ball 18 and a connecting rod 19 are arranged on the surface of the first scum plate 15; a first scraper 14 is arranged on the surface of the first scum plate 15; and a float ball 18 is fixed at the other end of the connecting rod 19. As the connecting rod 19 moves, and a spring 26 is provided on the outside of the connecting rod 19, one end of the spring 26 is fixed to the surface of the first scum plate 15 and the second scum plate 33. After the float 18 moves with the connecting rod 19, it can be held against the end of the spring 26. When the first scum plate 15 and the second scraper 22 pass through the arc plate 27 and the groove 28, the float 18 no longer floats due to buoyancy, so that the float 18 drives the connecting rod 19 to move, so that the first scraper 14 and the second scraper 22 move. When the first scum plate 15 and the second scum plate 33 pass through the bottom of the air outlet pipe 7, since the air outlet pipe 7 is inclined, the air blown out of the air outlet pipe 7 blows onto the surface of the force plate 32, so that the force plate 32 drives the first scraper 14 and the second scraper 22 to move.

[0030] Example 2: Based on Example 1, a fixing pipe 3 is fixed to the surface of the treatment tank 1. The fixing pipe 3 is fixed to the surface of the air inlet pipe 2. The vertical pipe 4 is located in the reaction tank 8, and an outlet hole 5 is opened on the surface of the vertical pipe 4. The interiors of the air inlet pipe 2 and the vertical pipe 4 are empty. The treatment liquid and air in the air inlet pipe 2 and the vertical pipe 4 can be injected into the reaction tank 8 through the outlet hole 5. Two sets of arc plates 27 are fixed. A groove 28 is provided between the two sets of arc plates 27. Discharge holes 29 are opened on both sides of the groove 28. The end of the discharge hole 29 is connected to the extraction device.

[0031] A U-shaped tube 6 is fixed to the surface of the treatment tank 1. The U-shaped tube 6 is located at the top of the treatment tank 1. An air outlet pipe 7 is fixed to the surface of the U-shaped tube 6. The air outlet pipe 7 is located at the bottom of the U-shaped tube 6. The interior of the air outlet pipe 7 and the U-shaped tube 6 is hollow. An air blowing device is connected inside the U-shaped tube 6. The gas in the U-shaped tube 6 is blown out through the air outlet pipe 7. Since the air outlet pipe 7 is inclined, the air blown out of the air outlet pipe 7 blows onto the surface of the force plate 32, causing the force plate 32 to drive the first scraper 14 and the second scraper 22 to move. After the float ball 18 moves, it presses against the surface of the spring 26, causing the first scraper 14 and the second scraper 22 to shake, further cleaning the residue on the surface of the first scum plate 15 and the second scum plate 33. The gas blown out of the air outlet pipe 7 can drive the scum to move.

[0032] Multiple sets of fixing blocks 11 are fixed to the surface of the processing tank 1. A driving device is installed inside each fixing block 11, driving a rotating shaft 12 to rotate. The rotating shaft 12 is inserted into the surface of the fixing block 11 and can rotate on the surface of the fixing block 11. A conveyor belt 13 is sleeved on the surface of the rotating shaft 12 and moves with the rotation of the rotating shaft 12. Two sets of conveyor belts 13 are provided, and fixing plates 17 are fixed to the surface of each conveyor belt 13. The fixing plates 17 move with the conveyor belts 13. A connecting rod 16 is fixed to the end of each fixing plate 17, and a first scum plate 15 and a second scum plate 33 are fixed to the end of each connecting rod 16. The first scum plate 15 and the second scum plate 33 move with the conveyor belt 13, and the first scum plate 15 and the second scum plate 33... The slag plate 33 is inclined. The first slag plate 15 and the second slag plate 33 are located between the two sets of connecting rods 16 and the fixed plate 17. The first slag plate 15 and the second slag plate 33 move at the top of the reaction tank 8. During the movement of the first slag plate 15 and the second slag plate 33, the bottom of the first slag plate 15 and the second slag plate 33 are in contact with the liquid surface inside the reaction tank 8. The surfaces of the first slag plate 15 and the second slag plate 33 are provided with through grooves 23. A connecting plate 21 is inserted into the through groove 23 and can move in the through groove 23. The ends of the connecting plate 21 are fixed with a first scraper 14 and a second scraper 22. The first scraper 14 and the second scraper 22 are respectively located on both sides of the first slag plate 15 and the second slag plate 33. As the docking plate 21 moves, one end of the first scraper 14 and the second scraper 22 abuts against the surface of the first scum plate 15 and the second scum plate 33. The surfaces of the first scum plate 15 and the second scum plate 33 are provided with telescopic holes 31 and limiting holes 30. A limiting rod 24 is inserted into the limiting hole 30, and a telescopic rod 25 is inserted into the telescopic hole 31. The telescopic rod 25 can move within the telescopic hole 31, and the limiting rod 24 can move within the limiting hole 30. A connecting rod 19 is inserted inside the first scum plate 15 and the second scum plate 33, and the end of the connecting rod 19 is connected to the end of the telescopic rod 25. The connecting rod 19 moves with the telescopic rod 25. A moving rod 20 is fixed to the end of the telescopic rod 25, and the moving rod 20 moves with the telescopic rod 25. The limiting rod 24... The end of the moving rod is fixed to the surface of the telescopic rod 25. The limiting rod 24 also moves with the telescopic rod 25. There are two sets of moving rods 20. One set of moving rods 20 is fixed to the surface of the first scraper 14, and the other set of moving rods 20 is fixed to the surface of the second scraper 22. After the moving rods 20 move, they drive the first scraper 14 and the second scraper 22 to move simultaneously. The sides of the first scraper 14 and the second scraper 22 that are close to each other abut against the surfaces of the first scum plate 15 and the second scum plate 33 and move to scrape off the scum on the surfaces of the first scum plate 15 and the second scum plate 33. There are two sets of force plates 32 fixed to the surfaces of the first scraper 14 and the second scraper 22. The force plates 32 are located at the two ends of the first scraper 14 and the second scraper 22 respectively.The position of the force-bearing plate 32 corresponds to the position of the air outlet pipe 7. When the first scum plate 15 and the second scum plate 33 move to the bottom of the air outlet pipe 7, the air blown out of the air outlet pipe 7 blows onto the surface of the force-bearing plate 32, causing the force-bearing plate 32 to move under force. The force-bearing plate 32 then drives the first scraper 14 and the second scraper 22 to move. The ends of the second scraper 22 and the first scraper 14 press against the surfaces of the first scum plate 15 and the second scum plate 33. The movement of the second scraper 22 and the first scraper 14 cleans the scum remaining on the surfaces of the first scum plate 15 and the second scum plate 33. When the first scum plate 15 and the second scraper 22 pass through the arc plate 27 and the groove 28, the float 18 no longer floats due to buoyancy, causing the float 18 to drive the connecting rod 19 to move.

[0033] Wastewater is located in reaction tank 8. Treatment liquid for the wastewater is injected into reaction tank 8 through outlet 5 via vertical pipe 4 and air inlet pipe 2, causing scum in the wastewater to float on the surface of the liquid. The drive mechanism inside fixed block 11 drives rotating shaft 12 to rotate, causing conveyor belt 13 to move. Fixed plate 17 and connecting rod 16 on the surface of conveyor belt 13 drive the first scum plate 15 and second scum plate 33 to move. During this movement, the first scum plate 15 and second scum plate 33 push the scum floating on the liquid surface into scum trough 9. The cleaned liquid enters from the bottom. In the clean water tank 10, the first scum plate 15 and the second scum plate 33 are inclined. Under the action of buoyancy, the float 18 floats in the liquid, allowing the connecting rod 19 to be inserted into the first scum plate 15. The connecting rod 19 is connected to the telescopic rod 25, allowing the telescopic rod 25 to extend out of the first scum plate 15. The first scum plate 15 drives the moving rod 20 and the limiting rod 24 to move. The limiting rod 24 acts as a limit and moves inside the first scum plate 15. After the moving rod 20 moves, it drives the first scraper 14 to move. The end of the first scraper 14 is fixed with a pair of... A connecting plate 21 is attached to the other end of which a second scraper 22 is fixed. The second scraper 22 moves together with the first scraper 14, and the ends of the second scraper 22 and the first scraper 14 press against the surfaces of the first scum plate 15 and the second scum plate 33. The movement of the second scraper 22 and the first scraper 14 cleans the scum remaining on the surfaces of the first scum plate 15 and the second scum plate 33. When the first scum plate 15 and the second scraper 22 pass through the arc plate 27 and the groove 28, the float 18 no longer floats due to buoyancy, causing the float 18 to drive the connecting rod 19 to move, so that the first scum plate 15 and the second scraper 22 move together. Scraper 14 and scraper 22 move, and when the first scum plate 15 and the second scum plate 33 pass the bottom of the vent pipe 7, the air blown out of the vent pipe 7 blows onto the surface of the force plate 32 because the vent pipe 7 is inclined. This causes the force plate 32 to drive the first scraper 14 and the second scraper 22 to move. After the float ball 18 moves, it presses against the surface of the spring 26, causing the first scraper 14 and the second scraper 22 to shake, further cleaning the residue on the surface of the first scum plate 15 and the second scum plate 33. The gas blown out of the vent pipe 7 can also drive the scum to move.
