[0012] Beneficial effects

[0013] This invention provides a methylamine wastewater treatment device. Compared with the prior art, it has the following advantages:

[0014] 1. This methylamine wastewater treatment device, by setting up an air pumping mechanism, starts the motor, and the motor drives the rotating rod to rotate through the bevel gear. The rotating rod drives the rotating plate to rotate, the rotating plate drives the movable rod to move, the movable rod drives the moving rod to move, and the moving rod drives the piston block to move. In this way, the gas inside the air cylinder is transported into the air pipe, then into the ring pipe, and finally discharged from the air outlet. This causes the liquid inside the treatment tower to bubble, thereby improving the liquid mixing efficiency.

[0015] 2. This methylamine wastewater treatment device, by setting a water-stopping mechanism, when the piston block pushes the gas inside the gas cylinder downward, the gas will push the lower blocking block to move, thus separating the lower blocking block and the lower blocking ring. The gas enters the interior of the gas pipe through the air inlet. When the piston block moves upward, the lower spring pushes the lower blocking block upward and closes with the lower blocking ring, sealing the bottom of the three-way pipe. This prevents liquid from being sucked into the gas pipe. At the same time, the external gas pushes the upper blocking block, and the external gas enters the interior of the three-way pipe and then enters the interior of the gas cylinder.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a methylamine wastewater treatment device, including a treatment tower 6, a support frame 7 fixed to the bottom of the treatment tower 6, a fixing frame 3 fixed to the top of the treatment tower 6, a motor 2 fixed to the top of the fixing frame 3, a stirring rod 22 provided inside the treatment tower 6, the output shaft of the stirring rod 22 passing through the treatment tower 6 and fixedly connected to the output shaft of the motor 2, a waste liquid inlet pipe 1 and a purified liquid inlet pipe 30 fixed to the top of the treatment tower 6, and an outlet pipe 8 fixed to the bottom of the treatment tower 6. An outlet pipe 19 is fixed to the top of the treatment tower 6. Activated carbon 20 is installed inside the outlet pipe 19. An air pumping mechanism 11 is installed on the outside of the treatment tower 6. The air pumping mechanism 11 includes a rotating rod 18, a rotating plate 15, a movable rod 14, a moving rod 13, a piston block 16, an air cylinder 9, an air pipe 12, and a ring pipe 21. A fixing block 17 is rotatably connected to the outer wall of the rotating rod 18. The bottom of the fixing block 17 is fixedly connected to the top of the treatment tower 6. The right end of the rotating rod 18 is fixedly connected to the left side of the rotating plate 15. The right end of the cylinder 9 is rotatably connected to the top of the movable rod 14, the bottom end of the movable rod 14 is rotatably connected to the top of the moving rod 13, the left side of the cylinder 9 is fixedly connected to the outer wall of the treatment tower 6, the outer wall of the piston block 16 is slidably connected to the inner wall of the cylinder 9, the bottom end of the moving rod 13 is fixedly connected to the top of the piston block 16, a water-stopping mechanism 10 is fixedly fixed at the bottom of the cylinder 9, the bottom end of the water-stopping mechanism 10 is fixedly connected to the right end of the air pipe 12, and the other end of the air pipe 12 is fixedly connected to the outer wall of the ring pipe 21. Multiple air outlets 29 are provided on the outer wall of the annular pipe 21. The output shaft of the motor 2 and the rotating rod 18 are connected by a bevel gear 4. When the motor 2 is started, the rotating rod 18 rotates the rotating plate 15. The rotating plate 15 moves the movable rod 14 and the moving rod 13. The moving rod 13 moves the piston block 16. In this way, the gas inside the air cylinder 9 can be transported into the interior of the air pipe 12, then into the interior of the annular pipe 21, and finally discharged from the air outlets 29. This can cause the liquid inside the treatment tower 6 to bubble.

[0023] Furthermore, the water-stopping mechanism 10 includes a three-way pipe 28, two fixing rings 23, two springs 24, two blocking blocks 25, and two blocking rings 26. The top end of the three-way pipe 28 is fixedly connected to the bottom end of the air cylinder 9, and the bottom end of the three-way pipe 28 is fixedly connected to the right end of the air pipe 12. The outer wall of the fixing ring 23 is fixedly connected to the inner wall of the three-way pipe 28. One side of the fixing ring 23 is fixedly connected to one end of the spring 24, and the other end of the spring 24 is fixedly connected to the blocking block 25. The outer wall of the blocking ring 26 is fixedly connected to the inner wall of the three-way pipe 28. The top of the blocking block 25 is opened... There are multiple air inlets 5, and multiple baffles 27 are fixed on the inner wall of the three-way pipe 28. When the piston block 16 pushes the gas inside the air cylinder 9 downward, the gas will push the lower blocking block 25 to move. The gas enters the air pipe 12 through the air inlet 5. When the piston block 16 moves upward, the lower spring 24 pushes the lower blocking block 25 upward and closes with the lower blocking ring 26, sealing the lower part of the three-way pipe 28. This prevents liquid from being sucked into the air pipe 12. At the same time, the external gas pushes the upper blocking block 25, and the external gas enters the interior of the three-way pipe 28 and then enters the interior of the air cylinder 9.

[0024] During operation, motor 2 is started, and motor 2 drives rotating rod 18 to rotate via bevel gear 4. Rotating rod 18 drives rotating plate 15 to rotate, rotating plate 15 drives moving rod 14 to move, moving rod 14 drives moving rod 13 to move, and moving rod 13 drives piston block 16 to move. This allows the gas inside the gas cylinder 9 to be transported into the gas pipe 12, then into the ring pipe 21, and finally discharged from the outlet 29. This causes the liquid inside the treatment tower 6 to bubble, improving the liquid mixing. When piston block 16 pushes the gas inside the gas cylinder 9 downward, the gas pushes the lower blocking block 25 to move, thus separating the lower blocking block 25 from the lower blocking ring 26. The gas then enters the gas pipe 12 through the inlet 5. When piston block 16 moves upward, the lower spring 24 pushes the lower blocking block 25 upward and closes it with the lower blocking ring 26, sealing the bottom of the three-way pipe 28. This prevents liquid from being sucked into the gas pipe 12. At the same time, external gas pushes the upper blocking block 25, and external gas enters the three-way pipe 28 and then into the gas cylinder 9.
