[0002] The wet strength agent is a new generation of non-toxic and odorless papermaking aid commonly used in the world at present, which can greatly improve the dry and wet strength of paper. It is suitable for the production of various papers with wet strength requirements. During the process of adding urea to the raw materials in the reaction kettle and the cooling process after the reaction, a large amount of ammonia gas will volatilize, so it is necessary to recycle and utilize the ammonia gas.

[0003] For example, an ammonia recovery and treatment device for wet strength agent processing with the patent number CN220918655U includes a box body and a water tank. A water tank is fixedly connected to the lower part inside the box body, and a motor is fixedly connected to the center of the bottom of the box body. A rotating shaft is fixedly connected to the output shaft of the motor. The top of the rotating shaft sequentially penetrates through the box body and the water tank and extends above the water tank.

When in use, through the mutual cooperation of the box body, water tank, motor, rotating shaft, stirring paddle, spraying mechanism, high-pressure water pump, water suction pipe, drain pipe, rotary joint, connecting pipe, water spraying pipe, atomizing nozzle, water outlet pipe and air inlet pipe, it solves the problem that the common ammonia recovery and treatment device for wet strength agent processing has a low recovery efficiency and cannot make ammonia dissolve in water quickly and thoroughly. However, when the ammonia gas in the above-mentioned document is incorporated into the interior of the tank body, the ammonia gas floats randomly in the tank body. The ammonia gas concentration near the air inlet pipe is relatively high, and the safety concentration on the side far from the air inlet pipe is relatively low. When treating the ammonia gas, the contact between the ammonia gas and water is relatively uneven. At the same time, when ammonia gas is introduced into the tank body through the air inlet pipe, the ammonia gas is easily discharged from the air inlet pipe. Content of the Utility Model

The connection positions of the rotating rod 7 with the tank body 1 and the water tank 5 are sealed;

[0023] The outer wall of the rotating rod 7 is rotatably connected to both the tank body 1 and the water tank 5 through bearings. A diffusion mechanism 3 is provided on the outer wall of the rotating rod 7. The diffusion mechanism 3 diffuses ammonia gas inside the tank body 1, increasing the contact area with water. A connecting rod 8 is fixedly connected to the outer wall of the rotating rod 7. The rotating rod 7 drives the connecting rod 8 to rotate. Both the tank body 1 and the water tank 5 are fixedly connected to the outer wall of one end of the first water pipe 9. The water tank 5 is communicated with the first water pipe 9. The other end of the first water pipe 9 is fixedly connected to a liquid pump 10. The first water pipe 9 is communicated with the liquid pump 10. The liquid pump 10 is fixedly connected to the outer wall of the tank body 1. The output end of the liquid pump 10 is fixedly connected to a second water pipe 11. The liquid pump 10 is communicated with the second water pipe 11. The outer wall of the end of the second water pipe 11 is fixedly connected to the tank body 1. A rotary joint 12 is fixedly connected to the end of the second water pipe 11. The internal structure of the rotary joint 12 is the same as that in a kind of ammonia gas recovery and treatment equipment for wet strength agent processing with the patent number CN220918655U. The rotary joint 12 is fixedly connected to a water spraying plate 13 through a pipeline. The water spraying plate 13 is fixedly connected to the upper end of the rotating rod 7. The rotating rod 7 drives the water spraying plate 13 to rotate.

[0024] The diffusion mechanism 3 includes a disc 301, a wedge-shaped ring 302, a cross plate 303, a slide rod 304, a sleeve 305 and a first spring 306. The outer wall of the disc 301 is slidably connected to the rotating rod 7. The rotating rod 7 drives the disc 301 to rotate. A keyway is provided between the rotating rod 7 and the disc 301. The lower surface of the disc 301 is fixedly connected to the wedge-shaped ring 302. The disc 301 drives the wedge-shaped ring 302 to rotate. The wedge-shaped ring 302 is in contact with the upper surface of the cross plate 303. The cross plate 303 drives the wedge-shaped ring 302 to move. The cross plate 303 is fixedly connected to the inner wall of the tank body 1.

[0025] The disc 301 is in contact with the lower end of the slide rod 304. The slide rod 304 can drive the disc 301 to move under the action of elasticity. The outer wall of the slide rod 304 is slidably connected to the sleeve 305. The slide rod 304 slides inside the sleeve 305. The sleeve 305 is fixedly connected to the inner wall of the tank body 1. A first spring 306 is provided inside the sleeve 305. Both ends of the first spring 306 are fixedly connected to the sleeve 305 and the slide rod 304 respectively.

When the wedge-shaped ring 302 rotates, it is always in contact with the cross plate 303 under the action of the slide rod 304, the sleeve 305 and the first spring 306. When the wedge-shaped ring 302 rotates, the cross plate 303 drives the wedge-shaped ring 302 to move in the vertical direction. The wedge-shaped ring 302 drives the disc 301 to move. When the disc 301 moves up and down, it stirs the ammonia gas inside the tank body 1, causing the ammonia gas to diffuse inside the tank body 1, increasing the contact between ammonia and water flow, and making the contact between ammonia and water more uniform when treating ammonia gas.

[0027] The one-way mechanism 4 includes a vertical rod 401, a support rod 402, a piston 403, a second spring 404 and a ring 405. The vertical rod 401 is fixedly connected inside the intake pipe 2. The outer wall of the vertical rod 401 is slidably connected to the outer wall of the support rod 402. The support rod 402 slides inside the vertical rod 401. The end of the support rod 402 is fixedly connected with a piston 403, and the piston 403 moves together with the support rod 402;

[0028] The outer wall of the support rod 402 is sleeved with a second spring 404. The two ends of the second spring 404 are respectively fixedly connected with the piston 403 and the vertical rod 401. The second spring 404 can drive the piston 403 to move under the elastic action. The outer wall of the piston 403 is in contact with the ring 405. The piston 403 and the ring 405 are in contact to block the inside of the intake pipe 2. The ring 405 is fixedly connected inside the intake pipe 2. The model of the spring is selected according to the actual use requirements as long as it meets the working needs;

[0029] When ammonia gas is introduced into the inside of the intake pipe 2, the ammonia gas drives the piston 403 to move to the right and separate from the ring 405. The piston 403 drives the slide bar 402 to slide to the right and compresses the second spring 404. The gas enters the inside of the tank body 1 through the intake pipe 2. When the ammonia gas stops being introduced, the second spring 404 drives the piston 403 to move in the reverse direction under the elastic action. The piston 403 and the ring 405 are in contact to block the inside of the intake pipe 2. When ammonia gas is introduced into the inside of the tank body 1 through the intake pipe 2, the ammonia gas is not easily discharged from the intake pipe 2.

[0030] Working principle:

[0031] When using the ammonia recovery and treatment equipment for wet strength agent processing to recover and treat the ammonia gas generated during wet strength agent processing, the ammonia gas generated during wet strength agent processing is introduced through the intake pipe 2;

[0032] Stage of preventing ammonia gas from being discharged from the intake pipe:

[0033] When ammonia gas is introduced into the inside of the intake pipe 2, the ammonia gas drives the piston 403 to move to the right and separate from the ring 405. The piston 403 drives the slide bar 402 to slide to the right and compresses the second spring 404. The gas enters the inside of the tank body 1 through the intake pipe 2. When the ammonia gas stops being introduced, the second spring 404 drives the piston 403 to move in the reverse direction under the elastic action. The piston 403 and the ring 405 are in contact to block the inside of the intake pipe 2. When ammonia gas is introduced into the inside of the tank body 1 through the intake pipe 2, the ammonia gas is not easily discharged from the intake pipe 2;

[0034] Ammonia gas treatment stage:

[0035] When ammonia gas enters the interior of the tank body 1, the motor 6 and the liquid pump 10 are started. The liquid pump 10 pumps out the water in the water tank 5 through the first water pipe 9, and pumps the water into the interior of the water spraying plate 13 through the second water pipe 11 and the rotary joint 12 and sprays it out. The motor 6 drives the rotating rod 7 to rotate, the rotating rod 7 drives the connecting rod 8 and the disc 301 to rotate, the disc 301 drives the wedge-shaped ring 302 to rotate. When the wedge-shaped ring 302 rotates, it always fits with the cross plate 303 under the action of the slide rod 304, the sleeve 305 and the first spring 306. When the wedge-shaped ring 302 rotates, the cross plate 303 drives the wedge-shaped ring 302 to move in the vertical direction. The wedge-shaped ring 302 drives the disc 301 to move. When the disc 301 moves up and down, it stirs the ammonia gas inside the tank body 1, so that the ammonia gas diffuses inside the tank body 1, increasing the contact between the safety and the water flow. When treating the ammonia gas, the contact between the ammonia gas and the water is relatively uniform, thereby improving the treatment effect of the ammonia gas. The water after treating the ammonia gas falls into the water tank 5, and the connecting rod 8 stirs the water in the water tank 5, increasing the mixing effect of the ammonia gas entering the water tank 5 and the water.
