Description

Technical Field

[0001] This utility model relates to the field of nylon polymerization wastewater treatment technology, and in particular to a nylon polymerization wastewater treatment device. Background Technology

[0002] In the treatment of nylon polymerization wastewater, organic matter needs to be degraded and nitrified in an aerobic tank. During the treatment process, high organic matter content may cause bubbles to appear in the treatment tank, affecting the integration of oxygen into the treatment liquid and thus affecting the treatment process. At the same time, since the wastewater contains sludge, it will gradually sink to the bottom of the tank during the reaction process, resulting in insufficient contact between sludge and organic matter, which will affect the wastewater treatment. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nylon polymerization wastewater treatment device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A nylon polymerization wastewater treatment device includes a treatment tank. A rotary motor is fixedly installed on the treatment tank. A reciprocating screw is fixedly installed on the output shaft of the rotary motor. A moving block is threaded onto the reciprocating screw. An opening is opened on the moving block. Two sets of bubble scraping structures are installed in the opening. Each bubble scraping structure includes multiple rotating shafts rotatably installed in the opening. A spur gear is fixedly installed on each of the multiple rotating shafts. The multiple adjacent spur gears mesh with each other. A rack is fixedly installed in the treatment tank. The rack meshes with one of the spur gears. A scraper is installed at the lower end of each of the multiple rotating shafts. A stirring assembly is installed in the treatment tank.

[0006] Preferably, the stirring assembly includes two rotating rods rotatably mounted in the treatment tank, each of the two rotating rods having a turntable fixedly mounted on it, the two turntables having multiple rotating shafts rotatably mounted together, multiple stirring paddles fixedly mounted on each of the rotating shafts, and spur gears fixedly mounted on each of the multiple rotating shafts. A gear ring is fixedly mounted in the treatment tank, and the multiple spur gears mesh with the gear ring.

[0008] Preferably, a plurality of pads are fixedly installed at the lower end of the treatment pool, and the lower ends of the plurality of pads are all provided with anti-slip textures.

[0009] Preferably, two sliding rods are fixedly installed on the treatment pool, and both sliding rods are slidably connected to the moving block.

[0010] Preferably, all of the impellers are made of corrosion-resistant materials.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The reciprocating screw rotates, driving the moving block to move, causing the spur gear on it to rotate under the drive of the rack, which in turn causes the rotating shaft and scraper to rotate, thus treating the air bubbles on the surface of the pool and preventing oxygen from being blocked and unable to dissolve in the pool water.

[0013] 2. Simultaneously, the rotation of the turntable causes the second spur gear to rotate on the gear ring, which in turn drives the second rotating shaft to rotate in the center and rotate on its own axis. This drives the stirring paddle to rotate and stir the tank, ensuring that the sludge remains suspended in the tank water without settling, allowing the organic matter to be evenly mixed with the sludge.

[0019] Reference Figures 1-4A nylon polymerization wastewater treatment device includes a treatment tank 1. A rotary motor 2 is fixedly installed on the treatment tank 1. The rotary motor 2 is existing technology and can rotate an object connected to its output shaft. A reciprocating screw 3 is fixedly installed on the output shaft of the rotary motor 2. The reciprocating screw 3 is existing technology and can make the object connected to it reciprocate when the rotation direction of the main shaft remains unchanged. A moving block 4 is threaded on the reciprocating screw 3. The moving block 4 has an opening. Two sets of bubble scraping structures are installed in the opening. The bubble scraping structure includes multiple rotating shafts 5 rotatably installed in the opening. Each of the multiple rotating shafts 5 is fixedly installed with a spur gear 6. The multiple adjacent spur gears 6 mesh with each other. A rack 7 is fixedly installed in the treatment tank 1. The rack 7 meshes with one of the spur gears 6. A scraper 8 is installed at the lower end of each of the multiple rotating shafts 5. A stirring assembly is installed in the treatment tank 1. Since there are two sets of bubble scraping structures, there is no connection between the two spur gears 6 at the edges of the two sets.

[0020] By starting the rotary motor 2, its output shaft drives the reciprocating screw 3 to rotate, which in turn drives the moving block 4 to reciprocate. This, in turn, moves the rotating shaft 5 and the scraper 8 on the moving block 4 to scrape away the bubbles on the treatment tank 1. At the same time, since the spur gear 6 on the rotating shaft 5 rotates on the rack 7, the rotation of one rotating shaft 5, along with the meshing transmission between multiple adjacent spur gears 6, causes multiple spur gears 6 to rotate simultaneously. Therefore, multiple scrapers 8 will rotate simultaneously. Thus, the scrapers 8 continuously rotate while reciprocating, thereby improving the efficiency of bubble removal and covering a large area of ​​the surface of the treatment tank 1, making the bubble treatment more uniform.

[0021] The stirring assembly includes two rotating rods rotatably mounted inside the treatment tank 1. Each rotating rod is fixedly mounted with a turntable 9. Multiple rotating shafts 10 are rotatably mounted on both rotating shafts 9. Multiple stirring paddles 11 are fixedly mounted on the rotating shafts 10. Spur gears 12 are fixedly mounted on each of the multiple rotating shafts 10. A gear ring 13 is fixedly mounted inside the treatment tank 1. The multiple spur gears 12 mesh with the gear ring 13. One of the rotating rods is connected to the reciprocating screw 3 via a belt drive assembly 14. The belt drive assembly 14 consists of two pulleys and a belt body, which is used to drive the rotation of the reciprocating screw 3. The belt body causes the pulleys to drive the rotating rod to rotate.

[0022] When the reciprocating screw 3 rotates, it drives the rotating rod to rotate through the belt drive assembly 14, which in turn drives the turntable 9 to rotate. This causes the rotating shaft 10 on the shaft 10 to rotate between the two turntables 9. During the rotation, the spur gear 12 on the rotating shaft 10 meshes with the gear ring 13. Therefore, when the rotating shaft 10 rotates at the center, it will rotate on its own axis. As a result, the stirring paddle 11 on the rotating shaft 10 will rotate and stir the treatment tank 1. This can stir the sludge in the wastewater, suspend it in the tank, and mix it evenly with the organic matter.

[0023] The treatment tank 1 has an opening, a guide plate 15 is fixedly installed on the opening, a limiting groove is fixedly installed on the guide plate 15, a sliding groove is opened inside the opening, a baffle 16 is slidably connected to the sliding groove and the limiting groove, a threaded rod 17 is threadedly connected to the baffle 16, the threaded rod 17 is rotatably connected in the sliding groove, a rotary motor 18 is fixedly installed on the treatment tank 1, and the output shaft of the rotary motor 18 is fixedly installed on the threaded rod 17.

[0024] Through the opening and the guide plate 15, a portion of the wastewater in the middle section of the treatment tank 1 can be taken out to test the wastewater treatment status of the treatment tank 1. At the same time, by rotating the motor 18 to drive the threaded rod 17 to rotate, the baffle 16 moves up and down to open and close the opening.

[0025] Multiple feet 19 are fixedly installed at the lower end of the treatment tank 1. The lower ends of the multiple feet 19 are all equipped with anti-slip textures. With the feet 19 and anti-slip textures, the staff can place the entire device stably in the designated position. Two sliding rods 20 are fixedly installed on the treatment tank 1. The sliding rods 20 are slidably connected to the moving block 4. The sliding rods 20 have a limiting function, so when the moving block 4 moves, it can prevent the moving block 4 from shaking. Multiple stirring paddles 11 are all made of corrosion-resistant materials. Using corrosion-resistant materials for the stirring paddles 11 can reduce the erosion of the stirring paddles 11 by wastewater and extend their service life.

[0026] The working principle of this invention is as follows: Starting the rotary motor 2 causes its output shaft to drive the reciprocating screw 3 to rotate, which in turn drives the moving block 4 to reciprocate. This, in turn, moves the rotating shaft 5 and scraper 8 on the moving block 4, scraping away bubbles on the treatment tank 1. Simultaneously, because the spur gear 6 on the rotating shaft 5 rotates on the rack 7, the rotation of one rotating shaft 5, coupled with the meshing transmission between multiple adjacent spur gears 6, causes them to rotate simultaneously. Consequently, multiple scrapers 8 rotate simultaneously, thus continuously rotating while reciprocating. This improves the efficiency of bubble removal and provides a large-scale coverage of the surface of the treatment tank 1, resulting in more uniform bubble treatment. The rotation of the reciprocating screw 3 is achieved through belt drive... Component 14 drives the rotating rod to rotate, which in turn drives the turntable 9 to rotate. This causes the rotating shaft 10 on the shaft to rotate between the two turntables 9. During the rotation, the spur gear 12 on the rotating shaft 10 meshes with the gear ring 13. Therefore, when the rotating shaft 10 rotates at the center, it will also rotate on its own axis. As a result, the stirring paddle 11 on the rotating shaft 10 will rotate and stir the treatment tank 1. This stirs the sludge in the wastewater, suspending it in the tank and allowing it to be evenly mixed with organic matter. Through the opening and the guide plate 15, a portion of the wastewater in the middle section of the treatment tank 1 can be taken out for testing the wastewater treatment status of the treatment tank 1. At the same time, by rotating the motor 18, the threaded rod 17 is rotated, causing the baffle 16 to move up and down, opening and closing the opening.
