Description

Technical Field

[0001] The utility model relates to the technical field of liquid agent stirring, in particular to a sizing agent reaction device for papermaking. Background Technique

[0002] A papermaking additive can endow paper and paperboard with properties such as ink resistance, water resistance, emulsion resistance, and corrosion resistance to improve smoothness, strength, and application period. It can be divided into internal sizing agents and surface sizing agents. Internal sizing agents are roughly divided into three categories: rosin-based sizing agents, synthetic sizing agents, and neutral sizing agents. Surface sizing agents generally use anionic polymer substances, and different additives in equal proportions need to be added to the inside during the production process for reaction and mixing;

[0003] The existing stirring equipment often performs directional stirring when stirring the sizing agent, so the liquid agent inside has a certain regularity during stirring, and often only by increasing the stirring time can the corresponding stirring effect be achieved, which requires more time.

[0004] Therefore, we propose a sizing agent reaction device for papermaking. Content of the Utility Model

Detailed implementation mode

[0023] Next, in combination with the drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-6 , the present invention provides a technical solution: a surface sizing agent reaction device for papermaking, including a reaction kettle 1, and a motor 20 is fixedly connected to the upper end of the reaction kettle 1,

[0025] a stirring assembly 2, the stirring assembly 2 is arranged below the motor 20 and is located inside the reaction kettle 1, which can cause the liquid agent inside the reaction kettle 1 to form convection, avoid the formation of rules in the flow of the liquid agent, and stir the liquid agent evenly;

[0026] an adjusting assembly 4, the adjusting assembly 4 is arranged on the outer surface of the stirring assembly 2 and cooperates with the stirring assembly 2 to further improve the stirring effect.

[0027] The stirring assembly 2 includes a first stirring rod 21, the lower end of the first stirring rod 21 is fixedly connected to the output end of the motor 20, a stirring blade 28 is arranged on the outer circumferential surface of the first stirring rod 21 near the lower end, a first gear 23 is rotatably connected to one side of the inner surface of the reaction kettle 1 near the first stirring rod 21 through a rotating shaft, a second stirring rod 22 is rotatably connected to the upper end of the inner surface of the reaction kettle 1 through a rotating shaft, the second stirring rod 22 is sleeved outside the first stirring rod 21, the gear 23 is arranged between the first stirring rod 21 and the second stirring rod 22 and meshes with both of them, and tooth grooves 24 are provided at corresponding positions of the first stirring rod 21, the second stirring rod 22 and the gear 23. After the motor 20 is started, it drives the first stirring rod 21 to rotate, and drives the second stirring rod 22 to rotate through the rotation of the first stirring rod 21, so as to perform double-layer stirring on the liquid agent inside the reaction kettle 1, thereby causing the liquid inside the reaction kettle 1 to form convection, breaking the rules of the liquid agent flow, and thus improving the stirring efficiency.

[0028] A swinging wing 25 is rotatably connected to the outer circumferential surface of the second stirring rod 22 through a rotating shaft. The position where the swinging wing 25 is connected to the second stirring rod 22 is a corner of the swinging wing 25. The setting of the swinging wing 25 can change the angle of the swinging wing 25 under the action of the centrifugal force generated when the second stirring rod 22 rotates, so as to change the stirring range with more centrifugal force during stirring, further improve the stirring effect, and break the inherent flow rules.

[0029] A blade 31 is fixedly connected to the inner surface of the second stirring rod 22 near the lower end. An exhaust port 30 is formed on the outer surface of the second stirring rod 22. When the second stirring rod 22 rotates, it drives the blade 31 to rotate rapidly. The blade 31 rotates to draw the liquid agent inside the reaction kettle 1 into the space between the first stirring rod 21 and the second stirring rod 22, and then discharges the liquid agent through the exhaust port 30, further enhancing the stirring effect on the liquid agent.

[0030] The adjusting assembly 4 includes a sliding ring 26. The stirring blade 28 is fixedly connected to the outer surface of the sliding ring 26. A guiding block 42 is fixedly connected to the inner surface of the sliding ring 26. A guiding groove 40 is formed at the corresponding position of the first stirring rod 21 and the guiding block 42. The guiding block 42 is located inside the guiding groove 40 to prevent the liquid agent from stratifying. When the first stirring rod 21 rotates, the centrifugal force drives the counterweight 45 and the slider 44 to slide along the sliding groove 43, and at the same time drives the sliding ring 26 to slide upward along the guiding groove 40 through the guiding block 42, thereby changing the height of the stirring blade 28. A sliding groove 43 is formed on the surface of the stirring blade 28. A slider 44 is slidably connected inside the sliding groove 43. One end of the slider 44 away from the sliding groove 43 is fixedly connected to a counterweight 45. A towing rope 41 is fixedly connected to the upper end of the inner surface of the guiding groove 40. The other end of the towing rope 41 passes through the sliding ring 26 and is fixedly connected to the slider 44. To prevent the liquid agent from stratifying, when the first stirring rod 21 rotates, the centrifugal force drives the counterweight 45 and the slider 44 to slide along the sliding groove 43, and at the same time pulls the towing rope 41, driving the sliding ring 26 to slide upward along the guiding groove 40 through the guiding block 42, thereby changing the height of the stirring blade 28 and then breaking the original flow rule of the liquid agent.
