It usually consists of two parts, the upper part is the distillation zone, and the lower part is the extraction zone. A series of evenly distributed sieve plates are arranged in the tower, and the sieve plates are covered with various fillers to increase the liquid-gas friction in the tower and improve the mass transfer and heat transfer effect. The working principle of the sieve plate distillation tower is to use the gas-liquid balance between components with different volatility to achieve the separation of substances. In the tower, the material flows up and down continuously under the action of gravity and siphon force, and gradually achieves the purification effect after multiple gas-liquid distribution, contact and turbulent mixing.

[0018] 1. The cleaning device for the sieve plate distillation tower starts the water pump and water tank, and the water pump and water tank will transport cleaning liquid into the rotating hexagonal tube through the connecting pipe. The cleaning liquid entering the rotating hexagonal tube will enter the four hose control cylinders and be evenly sprayed out from the lower ends of the four hose control cylinders. Then, the motor is started, and the output shaft of the motor drives another sprocket to rotate through the sprocket and chain thereon, and drives the gear shaft thereon to rotate at the same time. When the gear shaft rotates, it drives the helical gear thereon to rotate at the same time. When the helical gear rotates, it drives the helical gear ring and the rotating hexagonal tube thereon to rotate at the same time through its own teeth.

Through the operation of the above structure, every area on the inner wall of the sieve plate distillation tower body can be effectively flushed, avoiding the problem that when using flowing water to clean the inner wall of the sieve plate distillation tower body in the traditional way, the force of the water flow itself is not large enough, making it difficult to flush the residue clean, thus affecting the effect of next use.
[0019] 2. The cleaning device for the sieve plate distillation tower can enable the four elastic rubber hoses to rotate about the axis of the rotating hexagonal tube while swinging up and down through the uniform cleaning device, so as to directly wash most of the inner wall of the sieve plate distillation tower body to wash away the residues on the inner wall of the sieve plate distillation tower body, thereby avoiding the time-consuming and labor-intensive manual cleaning of the inner wall of the sieve plate distillation tower body in the traditional way, and improving the cleaning efficiency of the sieve plate distillation tower body to a certain extent.

A helical gear 12 is provided on the outer surface fixed sleeve of the gear shaft 11, and the helical gear 12 is meshed with the helical gear ring 10. A sprocket 13 is provided on the outer surface fixed sleeve of the gear shaft 11. A motor 15 is fixedly connected to the top cover 2 of the sieve plate distillation tower, and the outer surface fixed sleeve of the output shaft of the motor 15 is provided with the same sprocket 13. A chain 14 is transmission-connected between the two sprockets 13. A spring 18 is provided on the outer surface fixed sleeve of the rotating hexagonal tube 4, and the spring 18 is located between the rotating disk 9 and the helical gear ring 10. An eccentric wheel 19 is fitted with the lower surface of the rotating disk 9. A water pump water tank 16 is fixedly connected to the right surface of the gantry 3, and a connecting pipe 17 is fixedly connected to the output end of the water pump water tank 16. The end of the connecting pipe 17 away from the water pump water tank 16 is rotatably connected to the upper end of the rotating hexagonal tube 4.
[0027] Furthermore, when in use, by starting the water pump tank 16, the water pump tank 16 will transport cleaning liquid to the rotating hexagonal tube 4 through the connecting pipe 17, and the cleaning liquid entering the rotating hexagonal tube 4 will enter the four hose control tubes 7, and will be evenly sprayed out from the lower ends of the four hose control tubes 7, and then by starting the motor 15, the output shaft of the motor 15 drives another sprocket 13 to rotate through the sprocket 13 and the chain 14 thereon, and at the same time drives the gear shaft 11 thereon to rotate at the same time, and when the gear shaft 11 rotates, it will drive the bevel gear 12 thereon to rotate at the same time, and when the bevel gear 12 rotates, it will pass its own toothed belt The dynamic helical gear ring 10 and the rotating hexagonal tube 4 thereon can rotate at the same time. When the rotating hexagonal tube 4 rotates, the four elastic rubber hoses 5 thereon also rotate to evenly clean the inner wall of the sieve plate distillation tower body 1. The rotating output shaft of the motor 15 also drives the eccentric wheel 19 thereon to rotate. When the eccentric wheel 19 rotates, it applies an upward force to the rotating disk 9 through the eccentric protrusion thereon. When the rotating disk 9 is subjected to the force, it moves upward. At the same time, the spring 18 is compressed upward by its force until the eccentric protrusion on the eccentric wheel 19 rotates to the bottom.

At the same time, the cleaning liquid sprayed from the openings at the lower ends of the four flexible tube movable grooves 8 will move up and down on the inner wall of the sieve plate distillation tower body 1 to wash, until every area on the inner wall of the sieve plate distillation tower body 1 is aligned and washed. Through the operation of the above structure, every area on the inner wall of the sieve plate distillation tower body 1 can be effectively washed, avoiding the traditional method of using flowing water to wash the sieve plate distillation tower body. When the inner wall of the sieve plate distillation tower body 1 is cleaned, the force of the water flow itself is not strong enough to rinse the residues clean, which affects the effect of next use. By providing a uniform cleaning device, the four elastic rubber hoses 5 can rotate about the axis of the rotating hexagonal tube 4 while swinging up and down, so that most of the inner wall of the sieve plate distillation tower body 1 is directly rinsed to rinse off the residues on the inner wall of the sieve plate distillation tower body 1, avoiding the time-consuming and labor-intensive manual cleaning of the inner wall of the sieve plate distillation tower body 1 in the traditional way, and improving the cleaning efficiency of the sieve plate distillation tower body 1 to a certain extent.
[0028] Working principle: When in use, by starting the water pump tank 16, the water pump tank 16 will transport cleaning liquid to the rotating hexagonal tube 4 through the connecting pipe 17, and the cleaning liquid entering the rotating hexagonal tube 4 will enter the four hose control tubes 7, and be evenly sprayed out from the lower ends of the four hose control tubes 7, and then by starting the motor 15, the output shaft of the motor 15 drives another sprocket 13 to rotate through the sprocket 13 and the chain 14 thereon, and drives the gear shaft 11 thereon to rotate at the same time. When the gear shaft 11 rotates, it will drive the bevel gear 12 thereon to rotate at the same time. When the bevel gear 12 rotates, it will drive the bevel gear ring 10 and the rotating hexagonal tube 4 thereon to rotate at the same time through its own teeth. When the rotating hexagonal tube 4 rotates, the four elastic rubber hoses 5 thereon also rotate with it, so that the inner wall of the sieve plate distillation tower body 1 is evenly cleaned. The rotating output shaft of the motor 15 will also drive the eccentric wheel 19 thereon to rotate. When the eccentric wheel 19 rotates, it will apply an upward force to the rotating disk 9 through the eccentric protrusion thereon. The rotating disk 9 will move upward when the force is applied, and the spring 18 will be compressed upward by its force until the eccentric protrusion on the eccentric wheel 19 rotates downward. The spring 18 drives the rotating disk 9 downward to fit the outer contour of the eccentric wheel 19 through its own elastic force. When the rotating disk 9 moves up and down, it will drive the hose movable groove 8 on the hose control tube 7 to drive the four hose movable grooves 8 to open and close upward. At the same time, the cleaning liquid sprayed from the openings at the lower ends of the four hose movable grooves 8 will move up and down on the inner wall of the sieve plate distillation tower body 1 to flush until every area on the inner wall of the sieve plate distillation tower body 1 is aligned and flushed.
