[0034] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] like Figures 1-8As shown, an automatic cleaning device for an emulsion polymerization reactor includes a 360° rotating spray head system 300, a water pressure control system 200, a waste gas recovery system 500, a reactor wall rinsing system 400, and a data unit control system 100. The water pressure control system 200 is connected to the 360° rotating spray head system 300 and the reactor wall rinsing system 400 to change the water pressure sprayed by the 360° rotating spray head system 300 and the reactor wall rinsing system 400. The data unit control system 100 is connected to the 360° rotating spray head system 300, the water pressure control system 200, the waste gas recovery system 500, and the reactor wall rinsing system 400 to control the normal operation of each system.

[0036] Specifically, the 360° rotating sprinkler head system 300 includes a first controller, a sprinkler head 301, and a connecting pipe 302. The sprinkler head 301 is connected to the connecting pipe 302, which provides water flow to the sprinkler head 301. The first controller is connected to the water pressure control system 200 to control the water pressure sprayed from the sprinkler head 301.

[0037] The vessel wall rinsing system 400 includes a second controller, a movable rod 401, several brushes 405, and a water supply pipe 402. The brushes 405 are mounted on the movable rod 401, which is connected to the water supply pipe 402. The movable rod 401 has multiple slots, and the water supplied by the water supply pipe 402 sprays out from the slots. The second controller is connected to the water pressure control system 200 to control the pressure of the water sprayed out from the movable rod 401.

[0038] The automatic cleaning device for emulsion polymerization reactor also includes a mounting plate 601, a rotating wheel 603, a first transmission wheel 607, and a first transmission ring 604. The rotating wheel 603, the first transmission wheel 607, and the first transmission ring 604 are rotatably connected to the mounting plate 601. The rotating wheel 603 and the first transmission wheel 607 are located inside the first transmission ring 604.

The nozzle 301 is provided on the rotating wheel 603, and the movable rod 401 is provided on the first transmission ring 604.

[0039] The mounting plate 601 is provided with a second transmission ring 605, which is located outside the first transmission ring 604. The side wall of the movable rod 401 contacts the inner wall of the second transmission ring 605 and forms a transmission engagement with the second transmission ring 605. The motor is in transmission engagement with the rotating wheel 603. When the rotating wheel 603 rotates, it drives the first transmission ring 604 to rotate using the first transmission wheel 607. When the nozzle 301 rotates 360° with the rotating wheel 603, it drives the movable rod 401 to make a circular motion along the vessel wall. When the movable rod 401 moves, it contacts the second transmission ring 605. Under the action of the second transmission ring 605, the movable rod 401 rotates on its own axis as it rotates with the first transmission ring 604, which improves the contact effect between the bristles 405 and the vessel wall, and cleans the vessel wall in conjunction with the water spray.

[0040] Furthermore, the movable rod 401 has a hollow structure and is provided with multiple connecting blocks 404. The connecting blocks 404 are located in a slot, and a connecting shaft 406 is provided in the slot. The connecting blocks 404 are provided with connecting holes corresponding to the connecting shaft 406. The bristles 405 are provided on the connecting blocks 404, and the connecting blocks 404 are provided with multiple first through holes 4041.

The first connecting ring 407 is provided with a first movable groove, and a connecting rod 408 is provided in the first movable groove. One end of the connecting rod 408 is provided with a connecting rope 410, and the other end is provided with a return spring 409. One end of the return spring 409 is connected to the bottom of the first movable groove, and one end of the connecting rope 410 is fixed to the bottom side wall of the connecting block 404.

[0042] A push rod 403 is inserted into the movable rod 401. A push block 4032 is provided on the side wall of the push rod 403. The push rod 403 passes through the first connecting ring 407. The push block 4032 is located above the connecting rod 408. A groove 4042 for accommodating the push block 4032 is provided on the connecting block 404. The side wall of the groove 4042 is inclined.

[0043] The first transmission ring 604 is provided with a second movable groove, and a second connecting ring 606 is provided in the second movable groove. The push rod 403 is connected to the second connecting ring 606. The bottom of the second connecting ring 606 is provided with multiple support springs 610. The water supply pipe 402 passes through the second movable groove. The push rod 403 is provided with a first infusion chamber. The side wall of the first infusion chamber is provided with multiple second through holes 4031. The second through holes 4031 are located on one side of the connecting block 404.

[0044] The bottom of the mounting plate 601 is provided with multiple connecting springs 609, and a support plate 608 is provided on the connecting springs 609.

[0045] The rotor 603 is equipped with a connecting post 602, which passes through the mounting plate 601 for easy connection to the motor. The connecting post 602 has a second infusion chamber with multiple openings on its side wall. A third connecting ring 303 is fitted onto the connecting post 602. The connecting pipe 302 is connected to the third connecting ring 303. The third connecting ring 303 has an annular groove, which connects the groove to the connecting pipe 302. The water flow delivered by the connecting pipe 302 enters the nozzle 301 through the annular groove and the groove. The design of the third connecting ring 303 and the groove ensures that water can enter normally when the nozzle 301 rotates, so that it can be sprayed onto the vessel wall for cleaning.

[0046] The waste gas recovery system 500 includes an extraction pipe, an air pump, and a waste gas treatment pipeline network. After the material discharge from the reactor is completed, the extraction pipe is inserted into the reactor, and the air pump operates to extract the waste gas from the reactor. The waste gas enters the waste gas treatment pipeline network through the extraction pipe for treatment. After the extraction pipe is pulled out of the reactor, the mounting plate 601 is moved to the top of the reactor and placed on top of the reactor. The support plate 608 rests against the reactor. The nozzle 301 and the movable rod 40... 1. Inside the reactor, the motor drives the rotor 603 to rotate. Water flows through the connecting pipe 302 and the water supply pipe 402 to the nozzle 301 and the first infusion chamber. The water supply pipe 402 moves downward, causing the second connecting ring 606 to move. The second connecting ring 606 drives the push rod 403 to move towards the bottom of the movable rod 401. As the push rod 403 moves, the push block 4032 pushes the connecting rod 408 to move. At the same time, the push block 4032 moves out of the groove 4042 and presses against it. On the side wall of the connecting block 404, the pusher 4032 pushes the bottom of the connecting block 404 to flip outward. When the second connecting ring 606 moves to the bottom of the second movable groove, the connecting block 404 flips to a vertical position, and the bristles 405 flip to a horizontal position to contact the reactor wall. When the rotating wheel 603 rotates, it drives the nozzle 301 to rotate, ensuring the coverage of the spray from the nozzle 301. When the movable rod 401 rotates, the water in the first water supply chamber sprays out from the second through hole 4031. The water sprays onto the reactor wall through the first through hole 4041, working with the bristles 405 to clean the reactor wall and ensure the cleaning effect. When the movable rod 401 cleans the inner wall of the reactor, the mounting plate 601 intermittently squeezes the support plate 608, causing the mounting plate 601 to move relative to the support plate 608. The mounting plate 601 drives the movable rod 401 to move, ensuring the coverage of the bristles 405 and allowing the bristles 405 to contact the entire inner wall of the reactor.

[0047] After the reactor is cleaned, the water pipe 402 moves upward, the support spring 610 pushes the second connecting ring 606 to move, the push rod 403 moves upward and drives the push block 4032 to the groove 4042 position of the connecting block 404, the reset spring 409 pushes the connecting rod 408 to move upward, the connecting rope 410 pulls the bottom end of the connecting block 404 to flip into the movable rod 401, the bristles 405 are tilted downward, the water continues to spray out from the second through hole 4031, the water in the movable rod 401 flows out from the first through hole 4041 to rinse the bristles 405, wash off the impurities on the bristles 405, and avoid the bristles 405 causing secondary pollution to the inner wall of the reactor.

[0048] The advantage of this device is that it truly realizes one-step operation for cleaning the reactor, and can directly achieve the effect of automated cleaning control. While the cleaning efficiency is high, it also eliminates the previous manual disassembly and assembly process, improves work efficiency, and reduces workload. Most importantly, it solves the environmental and physical and mental health impacts of residual raw material odors caused by manual cleaning.
