Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for purifying wastewater generated during the production of polyether polymers. Background Technology

[0002] Polymer polyols, which are generally white or light milky yellow in appearance, are a type of polyol containing organic fillers. They can replace inorganic fillers and not only enable polyurethane foam to have higher load-bearing capacity and good resilience, but also improve the foam's cell structure and physical and mechanical properties. However, the production process of polyols generates wastewater that pollutes the environment, which requires wastewater treatment.

[0003] For example, the treatment device for polyether polyol production wastewater disclosed in Chinese Patent Publication No. CN215479979U includes a sludge biochemical tank. The sludge biochemical tank is equipped with a regulator addition mechanism and a stirring mechanism inside. The top of the sludge biochemical tank has a first feed hole and a second feed hole. A second feed valve extends outward from the top of the second feed hole. The regulator addition mechanism includes a first rotary motor, a telescopic cylinder, and a feed plate. The main body of the first rotary motor is fixed above the second feed valve. The rotating part of the first rotary motor is fixedly connected to the top of the telescopic cylinder. The bottom of the telescopic cylinder is fixedly connected to the middle of the feed plate. The feed plate has several circular feeding holes. The top of the feeding holes is connected to a regulator feed pipe. The regulator feed pipe is equipped with a plunger metering pump. By independently adding production wastewater and various regulators, the pressure inside the tank can be kept as stable as possible.

[0004] In the process of realizing this application, the inventors discovered that the technology has at least the following problems: Although the above technical solution can independently add various regulating agents and try to ensure the stability of the gas pressure inside the tank, when a large amount of powder is added and stirred, it is easy to clump together, which will affect the mixing and stirring with wastewater and reduce the treatment efficiency of wastewater. Therefore, further improvements can be made. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: a device for purifying wastewater generated during polyether polymer production, comprising a tank, a top cover on the top of the tank, three support legs arranged in an array at the bottom of the tank, a water inlet pipe fixedly connected to the top of the top cover, a drain pipe fixedly connected to the center of the bottom of the tank, a servo motor fixedly installed at the center of the top of the top cover, an independent intermittent dosing component arranged at the eccentric position on the top side of the top cover, and a mixing component for stirring arranged inside the tank.

[0006] As an optimization, the independent intermittent dispensing component includes a shaft rotatably connected to the top side of the top cover, and the shaft is fixedly installed at one end of the output shaft of the built-in motor. A rotating plate is fixedly installed at the top of the shaft, and a rotating column is rotatably connected to the end of the rotating plate. A rotating rod is rotatably connected to the top of the top cover, and a turntable is fixedly installed at the top of the rotating rod. The turntable has a movable groove inside, and the rotation trajectory of the rotating column is located within the movable groove. An installation plate is fixedly installed on the top side of the turntable, and a medicine container is fixedly installed inside the installation plate. The medicine container array is set on the top of the turntable, and multiple sets can be set according to the shape of the turntable. A dispensing component is set below the medicine container. By starting the built-in motor, the rotating plate will rotate, which will then drive the rotating column to rotate into the movable groove. After that, the turntable will rotate a quarter turn, thereby allowing the medicine container above the dispensing component to be replaced.

[0007] As an optimization, a positioning component is provided on the outer side of the rotating rod to restrict the rotation of the turntable. The positioning component includes a limiting frame fixedly installed on the top side of the top cover. A locking block is slidably connected inside the limiting frame. A spring is fixedly installed between the locking block and the bottom wall of the limiting frame. A locking groove is opened on the outer side of the rotating rod corresponding to the locking block. The locking block is engaged in the locking groove. An annular slide is opened on the outer side of the rotating rod corresponding to the locking groove. The spring force itself will cause the locking block to insert into the locking groove, thereby restricting the rotation of the turntable.

[0008] As an optimization, the dispensing assembly includes an electric telescopic rod fixedly installed inside the top of the top cover. A connecting plate is fixedly installed at the telescopic end of the electric telescopic rod, and an insertion tube is fixedly installed at the end of the connecting plate. The insertion tube is installed directly below the medicine tank via a metering pump. A through pipe is provided directly below the insertion tube, and the through pipe passes through the top cover and enters the tank body. The top of the through pipe is connected to the bottom of the insertion tube. By activating the electric telescopic rod, the connecting plate is moved upward, which in turn causes the insertion tube to be inserted into the medicine tank.

[0009] As an optimization, a retractable corrugated tube made of rubber is connected between the bottom of the insertion tube and the top of the through tube.

[0010] As an optimization, the bottom of the medicine container is fixedly equipped with a can opening, and the can opening is internally arranged with six plugs, which are inserted into the can opening.

[0011] As an optimization, the mixing component includes a rotating shaft fixedly installed at the bottom of the output shaft of the servo motor. A stirring frame is fixedly installed on the outside of the rotating shaft, and two sets of stirring frames are symmetrically arranged vertically. A stirring rod is rotatably connected between the ends of the two sets of stirring frames. A spiral blade is rotatably connected to the outside of the stirring rod. By starting the drain pipe, the rotating shaft will be driven to rotate, which in turn will drive the surrounding stirring rods to rotate around the rotating shaft, thus stirring and mixing the wastewater in the tank.

[0012] The beneficial effects of this utility model are: 1. This equipment can purify wastewater generated during the production of polyether polymers. The rotating plate drives the rotating column to slide into the movable tank, which in turn drives the turntable to rotate a quarter turn, so that the medicine tank can be changed intermittently. Then, the electric telescopic rod drives the connecting plate to move upward, so that the insertion tube is inserted into the tank opening, and the medicine in the medicine tank can be discharged into the tank along the through pipe, thus enabling independent intermittent drug dispensing.

[0013] 2. This equipment, which can purify wastewater generated during the production of polyether polymers, will cause the rotating shaft to rotate when the drain pipe is started. This will cause the surrounding stirring rods to rotate around the rotating shaft, thereby stirring and mixing the wastewater in the tank. At the same time, the spiral blades will rotate when in contact with the wastewater, which will further mix the wastewater locally and break up large pieces of powder, improving the mixing efficiency of wastewater and reagents.

[0017] 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.

[0018] Please see Figure 1 A device for purifying wastewater generated during the production of polyether polymers includes a tank 1, a top cover 2 on the top of the tank 1, three support legs 3 arranged in an array at the bottom of the tank 1, a water inlet pipe 4 fixedly connected to the top of the top cover 2, a drain pipe 5 fixedly connected to the center of the bottom of the tank 1, a servo motor 6 fixedly installed at the center of the top of the top cover 2, an independent intermittent dosing component 7 arranged at the eccentric position on the top side of the top cover 2, and a mixing component for stirring arranged inside the tank 1.

[0019] Please see Figure 2 The independent intermittent dosing assembly 7 includes a shaft 8 rotatably connected to the top side of the top cover 2, and the shaft 8 is fixedly installed at one end of the output shaft of the built-in motor. A rotating plate 9 is fixedly installed on the top of the shaft 8, and a rotating column 10 is rotatably connected to the end of the rotating plate 9. A rotating rod is rotatably connected to the top of the top cover 2, and a turntable 11 is fixedly installed at the top of the rotating rod. A movable groove 12 is opened inside the turntable 11, and the rotation trajectory of the rotating column 10 is located within the movable groove 12. A mounting plate 13 is fixedly installed on the top side of the turntable 11. A medicine tank 14 is fixedly installed on the side. The array of medicine tanks 14 is set on the top of the turntable 11. Multiple sets can be set according to the shape of the turntable 11. A medicine dispensing component is set below the medicine tank 14. By starting the built-in motor, the rotating plate 9 will rotate, which will drive the rotating column 10 to rotate into the movable slot 12. Then, the turntable 11 will rotate a quarter turn, which can replace the medicine tank 14 above the medicine dispensing component. The medicine in different medicine tanks 14 can be dispensed into the tank through the medicine dispensing component, so that medicine can be added intermittently and independently. Please see Figure 3The outer side of the rotating rod is provided with a positioning component to restrict the rotation of the turntable 11. The positioning component includes a limiting frame 111 fixedly installed on the top side of the top cover 2. A locking block 112 is slidably connected inside the limiting frame 111. A spring 113 is fixedly installed between the locking block 112 and the bottom wall of the limiting frame 111. A locking groove 114 is opened on the outer side of the rotating rod corresponding to the locking block 112. The 112 is locked in the locking groove 114. An annular slide rail 115 is opened on the outer side of the rotating rod corresponding to the locking groove 114. The spring 113 will cause the locking block 112 to insert into the locking groove 114 by its own elastic force, thereby restricting the rotation of the rotating rod. The turntable 11 can be positioned after rotating a quarter turn. Please see Figure 4 The dispensing assembly includes an electric telescopic rod 15 fixedly installed inside the top of the top cover 2. A connecting plate 16 is fixedly installed at the telescopic end of the electric telescopic rod 15. An insertion tube 17 is fixedly installed at the end of the connecting plate 16. The insertion tube 17 is installed directly below the medicine tank 14 via a metering pump. A through pipe 18 is provided directly below the insertion tube 17. The through pipe 18 passes through the top cover 2 and enters the tank body 1. The top of the through pipe 18 is connected to the bottom of the insertion tube 17. By starting the electric telescopic rod 15, the connecting plate 16 is moved upward, which in turn causes the insertion tube 17 to be inserted into the medicine tank 14. Then, the metering pump is started to draw out the medicine from the medicine tank 14 in a quantitative manner, so that the medicine in the medicine tank 14 can be discharged downward into the tank through the through pipe 18. Please see Figure 4 A retractable corrugated tube 19 is connected between the bottom of the insertion tube 17 and the top of the through tube 18. The corrugated tube 19 is made of rubber. A can opening 20 is fixedly installed at the bottom of the medicine can 14. Six plugs 21 are arranged in an array inside the can opening 20, and the six plugs 21 are blocked inside the can opening 20. Please see Figure 5 The mixing component includes a rotating shaft 22 fixedly installed at the bottom of the output shaft of the servo motor 6. A stirring frame 23 is fixedly installed on the outside of the rotating shaft 22, and two sets of stirring frames 23 are symmetrically arranged vertically. A stirring rod 24 is rotatably connected between the ends of the two sets of stirring frames 23. A spiral blade 25 is rotatably connected to the outside of the stirring rod 24. By starting the drain pipe 5, the rotating shaft 22 will be driven to rotate, which will in turn drive the stirring rod 24 around the rotating shaft 22 to rotate. Therefore, the wastewater in the tank will be stirred and mixed. At the same time, the spiral blade 25 can further mix the wastewater locally and break up large pieces of powder, improving the mixing efficiency of wastewater and medicine.

[0020] In use, wastewater is first discharged into the tank 1 through the inlet pipe 4. Then, the built-in motor is started to drive the shaft 8 to rotate, which in turn drives the rotating column 10 to rotate into the movable groove 12 through the rotating plate 9. This causes the turntable 11 to rotate a quarter turn, allowing the medicine tank 14 at the top to be replaced intermittently. At the same time, by starting the electric telescopic rod 15, the connecting plate 16 drives the insertion tube 17 to be inserted upward into the tank opening 20, which then discharges the medicine in the medicine tank 14 downward into the tank along the through pipe 18. When the insertion tube 17 is pulled downward, the plug 21 will block the tank opening 20 to prevent the medicine from spilling. This allows for intermittent and independent dispensing of medicine. At the same time, starting the drain pipe 5 will drive the rotating shaft 22 to rotate, which will cause the surrounding stirring rods 24 to rotate around the rotating shaft 22, thereby stirring and mixing the wastewater in the tank. Meanwhile, the spiral blades 25 will rotate when in contact with the wastewater, which will further stir the wastewater locally and break up large pieces of powder.

[0021] In summary, this equipment for purifying wastewater generated during polyether polymer production uses a rotating plate 9 to drive a rotating column 10 into a movable trough 12, which in turn drives a turntable 11 to rotate a quarter turn. This allows for intermittent replacement of the medicine tank 14. Furthermore, an electric telescopic rod 15 drives a connecting plate 16 to move upward, which in turn drives a tube 17 to be inserted into the tank opening 20. This allows the medicine in the medicine tank 14 to be discharged downward into the tank along the through pipe 18, thus enabling independent intermittent drug dispensing.

[0022] Activating the drain pipe 5 will cause the rotating shaft 22 to rotate, which in turn will cause the surrounding stirring rods 24 to rotate around the rotating shaft 22, thereby stirring and mixing the wastewater in the tank. At the same time, the spiral blades 25 will rotate upon contact with the wastewater, further mixing the wastewater locally and breaking up large pieces of powder, thus improving the mixing efficiency of wastewater and medicine.
