Description

Technical Field

[0001] This utility model relates to the field of caprolactam alkaline solution recovery technology, specifically to a caprolactam alkaline solution recovery and wastewater treatment device. Background Technology

[0002] Caprolactam alkaline solution usually refers to an aqueous solution of caprolactam under alkaline conditions. Caprolactam alkaline solution recovery and wastewater treatment equipment is a complete set of process equipment mainly for the treatment and recovery of wastewater generated during the production of caprolactam.

[0003] A search of Chinese patent CN221027750U reveals a wastewater treatment device, including a treatment tank with an internal cavity. Multiple supports are evenly fixed to the bottom of the treatment tank. A water inlet pipe connects to the top of the treatment tank, a drain pipe connects to the bottom, and a feed pipe connects to one side. A driven rotating rod is rotatably connected inside the treatment tank, and multiple stirring plates are fixed to the outer surface of the driven rotating rod. A transmission chamber is fixed to the top of the treatment tank and connects to the middle of the water inlet pipe. The transmission chamber contains a drive assembly for rotating the driven rotating rod. The driving force generated by the driven rotating rod and the transmission chamber drives the driven rotating rod to rotate, achieving a stirring effect, further saving energy, and facilitating the initiation of the stirring function. The feed pipe also facilitates the filling of the treatment tank with water treatment agent.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. During the recovery of caprolactam alkaline solution and wastewater treatment, the staff needs to take samples for testing to understand the chemical reaction effect of the chemical agents on the solution. However, the solution inside the treatment equipment is not convenient for the staff to take samples, which makes the sampling work difficult. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a caprolactam alkaline solution recovery and wastewater treatment device.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] This utility model provides a caprolactam alkaline solution recovery and wastewater treatment device, including a treatment body. The treatment body is provided with an inlet, a drug inlet, a solid outlet, a liquid outlet, and a gas outlet. A fixed pipe is fixedly installed on the treatment body. A long pipe is movably installed inside the fixed pipe. A circular hole is opened at one end of the long pipe. A piston block is movably installed on the inner wall of the long pipe. A piston rod is fixedly installed on the piston block. A threaded shell is fixedly installed at the circular hole of the long pipe. A threaded opening is threaded on the threaded shell. A sampling bottle is connected to the end of the threaded opening. A stirring mechanism is provided at the other end of the long pipe. A driving mechanism is provided on the treatment body.

[0008] Furthermore, the long tube has two threads.

[0009] Furthermore, a sealing ring that fits into the piston rod is provided at one end of the long tube.

[0010] Furthermore, a sealing sleeve is installed on a common thread on one of the threads of the fixed tube and the long tube.

[0011] Furthermore, the stirring mechanism includes a limiting ring fixedly installed at the other end of the long tube, and the limiting ring abuts against the fixed tube, and two stirring rods are symmetrically fixedly installed on the limiting ring.

[0012] Furthermore, a first gear is fixedly installed at one end of the long tube.

[0013] Furthermore, the driving mechanism includes a drive motor disposed on the processing body, a limit plate is fixedly installed on the output end of the drive motor, and a second gear adapted to the first gear is fixedly installed on the limit plate.

[0014] The above-described solution of this utility model has at least the following beneficial effects:

[0015] 1. In this utility model, a long tube is inserted into the solution inside the treatment body, and then the piston block is moved out of the inside of the long tube by pushing the piston rod, so that the solution enters the inside of the long tube. Then, the piston block is moved back into the inside of the long tube by pulling the piston rod, and the solution in the long tube continues to enter the inside of the sampling bottle through the threaded shell and threaded opening. Then, by unscrewing the threaded opening, it is convenient for the staff to sample the solution inside the sampling bottle.

[0016] 2. In this utility model, by unscrewing the sealing sleeve out from the outside of the fixed tube and the current thread of the long tube, the sealing sleeve is moved to another thread of the long tube for fixation. The long tube is moved so that the first gear contacts the limiting plate. At the same time, the first gear meshes with the second gear, controlling the drive motor to run. The second gear and the first gear drive the long tube to rotate, so that the long tube drives the stirring rod through the limiting ring to stir the solution inside the treatment body. After stirring until uniform, the solution is sampled, thereby improving the accuracy of the sampling and testing results. Attached Figure Description

[0025] like Figures 1 to 5As shown, an embodiment of this utility model provides a caprolactam alkaline solution recovery and wastewater treatment device, including a treatment body 1, which is provided with an inlet 2, a drug inlet 3, a solid outlet 4, a liquid outlet 5 and a gas outlet 6.

[0026] In this embodiment of the invention, the operator connects the inlet 2, the drug inlet 3, the solid outlet 4, the liquid outlet 5, and the gas outlet 6 to external related equipment via connecting parts. The operator controls the external conveying equipment to transport the caprolactam alkaline solution recovery wastewater into the inner side of the treatment body 1 through the inlet 2. The operator controls the external drug delivery equipment to transport the chemical agent into the inner side of the treatment body 1 through the drug inlet 3 to react chemically with the solution. The treatment body 1 separates the solution. The operator controls the external pumping equipment to pump the filtered solids in the treatment body 1 through the solid outlet 4 and the filtered liquids through the liquid outlet 5. The operator controls the external suction equipment to extract the gas generated in the treatment body 1 through the gas outlet 6.

[0027] Figures 1 to 5 As shown, a fixed tube 7 is fixedly installed on the processing body 1. A long tube 8 is movably installed on the inner side of the fixed tube 7. A round hole is opened at one end of the long tube 8. A piston block 12 is movably installed on the inner wall of the long tube 8. A piston rod 13 is fixedly installed on the piston block 12. A threaded shell 18 is fixedly installed at the round hole of the long tube 8. A threaded opening 19 is threaded on the threaded shell 18. A sampling bottle 20 is connected to the end of the threaded opening 19. Two threads are opened on the long tube 8. A sealing ring 801 that fits into the piston rod 13 is provided at one end of the long tube 8. A sealing sleeve 9 is threaded on a common thread on one thread of the fixed tube 7 and the long tube 8.

[0028] In this embodiment of the invention, the operator inserts the long tube 8 into the solution inside the processing body 1, then pushes the piston rod 13 to move the piston block 12 out of the long tube 8, allowing the solution to enter the long tube 8. Then, by pulling the piston rod 13, the piston block 12 is moved back into the long tube 8, and the solution in the long tube 8 continues to flow through the threaded shell 18 and the threaded opening 19 into the sampling bottle 20. By unscrewing the threaded opening 19, the operator can easily sample the solution inside the sampling bottle 20.

[0029] Figures 1 to 5As shown, a stirring mechanism is provided at the other end of the long tube 8, and a driving mechanism is provided on the processing body 1. The stirring mechanism includes a limiting ring 10 fixedly installed at the other end of the long tube 8, and the limiting ring 10 abuts against the fixed tube 7. Two stirring rods 11 are symmetrically fixedly installed on the limiting ring 10. A first gear 14 is fixedly installed at one end of the long tube 8. The driving mechanism includes a driving motor 15 provided on the processing body 1. A limiting plate 16 is fixedly installed on the output end of the driving motor 15. A second gear 17 adapted to the first gear 14 is fixedly installed on the limiting plate 16.

[0030] In this embodiment of the utility model, the operator unscrews the sealing sleeve 9 from the outside of the fixing tube 7 and the current thread of the long tube 8, moves the sealing sleeve 9 to another thread of the long tube 8 for fixing, moves the long tube 8 so that the first gear 14 contacts the limiting plate 16, and at the same time, the first gear 14 meshes with the second gear 17. The long tube 8 drives the stirring rack to move into the solution inside the processing body 1 through the limiting ring 10, controls the drive motor 15 to run, and drives the long tube 8 to rotate through the second gear 17 and the first gear 14, so that the long tube 8 drives the stirring rod 11 to stir the solution inside the processing body 1 through the limiting ring 10. After stirring until uniform, sampling is performed, thereby improving the accuracy of the sampling and testing results.

[0031] Working principle: The operator controls an external conveying device to transport caprolactam alkaline solution recovery wastewater through inlet 2 into the inner side of the treatment body 1. An external dosing device delivers chemical agents through inlet 3 to the inner side of the treatment body 1 to react with the solution. The sealing sleeve 9 is unscrewed from the outer side of the fixing pipe 7 and the current thread of the long pipe 8, and then moved to another threaded location on the long pipe 8 for fixation. Moving the long pipe 8 causes the first gear 14 to contact the limiting plate 16. Simultaneously, the first gear 14 meshes with the second gear 17, controlling the drive motor 15 to operate. The second gear 17 and the first gear 14 drive the long pipe 8 to rotate, causing the long pipe 8 to drive the stirring rod 11 through the limiting ring 10 to stir the solution inside the treatment body 1. After stirring until uniform, the long pipe 8 is inserted... The solution is introduced into the solution inside the treatment body 1. Then, by pushing the piston rod 13, the piston block 12 is moved out of the inside of the long tube 8, allowing the solution to enter the inside of the long tube 8. Then, by pulling the piston rod 13, the piston block 12 is moved back into the inside of the long tube 8, and the solution in the long tube 8 continues to enter the inside of the sampling bottle 20 through the threaded shell 18 and the threaded opening 19. Then, the threaded opening 19 is unscrewed to perform sampling and testing. After the test is passed, the long tube 8 is moved back to the initial position and sealed using the sealing sleeve 9. The solution is separated by the treatment body 1. The external pumping device is controlled to pump the filtered solids in the treatment body 1 through the solid outlet 4 and the filtered liquid through the liquid outlet 5. The external suction device is controlled to extract the gas generated in the treatment body 1 through the gas outlet 6.
