[0002] In the papermaking industry, the main function of wet strength agents is to improve the wet strength of paper, enabling it to maintain a certain strength and durability in humid environments. During production, wet strength agents need to be added to cold water in different proportions according to dosage and stirred evenly. After stirring evenly, the mixture is then slowly added to the post-refining tank or pulping tank for production operations. In traditional manual stirring operations, the operators are prone to fatigue due to high labor intensity, which can lead to uneven stirring of the wet strength agent. This results in uneven distribution of the wet strength agent in the pulp during subsequent production, thereby reducing the paper's wet strength properties, tensile strength, and tear resistance, causing paper quality problems.

Multiple thermometers 2 are also installed on the side of the temperature control panel 3, so that the operator can easily control the temperature of the mixing tank 4 according to the production needs.

[0018] like Figure 4 As shown, the stirring component includes a servo motor 7, a rotating shaft 22, scrapers 23, and stirring rods 24. The servo motor 7 is fixedly mounted on the sealing cover 5, with its output shaft facing the inner cavity of the stirring tank 4. A rotating shaft 22 is mounted on the output shaft of the servo motor 7, and several stirring rods 24 are horizontally and alternately inserted into the rotating shaft 22 from top to bottom. The servo motor 7 drives the rotating shaft 22 to rotate, causing the stirring rods 24 on the rotating shaft 22 to rotate and stir the solvent in the stirring tank 4. Scrapers 23 are provided at both ends of the stirring rods 24. Figure 7As shown, the scraper 23 is a triangular prism, with one edge of the prism facing the inner wall of the mixing tank 4. The dimensions of the stirring rod 24 and the scraper 23 are matched with the inner diameter of the mixing tank 4. The servo motor 7 drives the rotating shaft 22 to rotate, thereby driving the stirring rod 24 and the scraper 23 to rotate. The stirring rod 24 stirs the wet strength agent solvent, and the scraper 23 scrapes off the wet strength agent adhering to the inner wall of the mixing tank 4, ensuring that the wet strength agent is fully stirred and diluted.

[0019] like Figure 3 As shown, the filter component includes a filter tube 14, a filter screen 17, a fixing screw 18, a first connecting end cap 19, a sealing port 20, and a second connecting end cap 21. The filter tube 14 has multiple layers of filter screen 17 inside, which filters the diluted wet strength agent liquid to ensure that pure wet strength agent enters the pulp. One end of the filter tube 14 is equipped with a first connecting end cap 19, and the other end is equipped with a second connecting end cap 21. Sealing ports 20 are provided on both the first connecting end cap 19 and the second connecting end cap 21. Figure 2 As shown, the first connecting end cap 19 is connected to the second flange connecting pipe 13 by fixing screws 18, the end of the second connecting end cap 21 is connected to the third flange connecting pipe 15, and the third flange connecting pipe 15 is connected to the transport pipe 9.

[0020] like Figure 1 , Figure 5 As shown, the inlet end of the feed inlet 6 is connected to a wet strength agent and a pure water inlet pipe assembly. The inlet pipe assembly includes a Y-type connector 25, a first electric switch valve 26, a first flow meter 27, a second electric switch valve 28, a second flow meter 29, a pure water inlet pipe 35, and a wet strength agent inlet pipe 36. The inlet end of the feed inlet 6 is connected to the Y-type connector 25. One end of the Y-type connector 25 is connected to the pure water inlet pipe 35, and the other end is connected to the wet strength agent inlet pipe 36. The first electric switch valve 27 is installed on the pure water inlet pipe 35. 6. A first flow meter 27 is installed at the rear end of the first electric switch valve 26. The first flow meter 27 is used to detect the amount of pure water flowing in. When the amount of pure water reaches the required amount, the first electric switch valve 26 is activated, closing the pipeline passage. A second electric switch valve 28 is installed on the wet strength agent inlet pipe 36. A second flow meter 29 is installed at the rear end of the second electric switch valve 28. The second flow meter 29 is used to detect the amount of wet strength agent flowing out. When the amount of wet strength agent reaches the required amount, the second electric switch valve 28 is activated, closing the pipeline passage. Because the amount of pure water is greater than the amount of wet strength agent, the diameter of the pure water inlet pipe 35 is greater than the diameter of the wet strength agent inlet pipe 36.

[0021] like Figure 1 , Figure 6As shown, the discharge port of pump 11 is equipped with a first flange connecting pipe 12, which is connected to the discharge port connecting pipe 30. The discharge port connecting pipe 30 transports the wet strength agent used in the operation to the paper production area. A third flow meter 31 is installed on the discharge port connecting pipe 30. The third flow meter 31 is used to detect the amount of wet strength agent flowing out. A third electric switch valve 32 is installed at the rear end of the third flow meter 31. When the amount of wet strength agent flowing out reaches the required amount, the third electric switch valve 32 is activated to close the pipeline channel.

[0022] During equipment operation, the amounts of wet strength agent and purified water to be introduced into the mixing tank 4 are first set according to the required concentration of the wet strength agent after dilution. The wet strength agent is introduced into the mixing tank 4 through the wet strength agent inlet pipe 36, and the purified water is introduced into the mixing tank 4 through the purified water inlet pipe 35. After the first flow meter 27 detects that the purified water has reached the predetermined amount, the first electric switch valve 26 is activated, closing the pipeline channel of the purified water inlet pipe 35, and the purified water supply stops. After the second flow meter 29 detects that the wet strength agent has reached the predetermined amount, the second electric switch valve 28 is activated, closing the pipeline channel of the wet strength agent inlet pipe 36, and the wet strength agent supply stops. The servo motor 7 is started, and the servo motor... Machine 7 drives the rotating shaft 22 to rotate, which in turn drives the stirring rod 24 and scraper 23 to rotate. The stirring rod 24 stirs the wet strength agent solvent, and the scraper 23 scrapes off the wet strength agent adhering to the inner wall of the mixing tank 4, ensuring that the wet strength agent is fully stirred and diluted. The concentration sensor 34 monitors the stirring of the solvent in the mixing tank 4 in real time. When the solvent is stirred evenly, the pump 11 starts, and the solvent in the mixing tank 4 is output through the transport pipe 9. The evenly stirred solvent passes through the filter pipe 14 and the filter screen 17, and is output through the discharge port connecting pipe 30. The solvent is transported to the post-grinding tank or slurry tank for production operations. When the outflow of wet strength agent reaches the required amount, the third electric switch valve 32 starts to close the pipeline channel. During the production process, under the control of the control panel 10, the flow meter and electric switch valve automatically control the amount of pure water and wet strength agent added, the stirring components automatically stir, the concentration sensor determines the uniformity of the stirred mixed solution, and automatically outputs a quantitative amount of diluted solvent to the next production area. Automatic temperature control ensures the stability of the diluted solution, improves production efficiency, and ensures product quality.
