Description

Technical Field

[0001] The invention relates to the technical field of papermaking wet strength agents, in particular to a quantitative conveying system for anti-deposition wet strength agents. Background Art

[0002] In the modern papermaking industry, the quality requirements for paper are becoming increasingly stringent. Wet strength agents are key chemical additives for improving the strength of paper in a wet state and are widely used. Many types of wet strength agents, such as common urea-formaldehyde resins and melamine formaldehyde resins, show a strong tendency to deposit during storage and transportation due to their own chemical structure and physical properties. From the perspective of chemical structure, these wet strength agent molecules often have a large molecular weight and complex functional groups, strong intermolecular interactions, and are easy to aggregate to form large molecular clusters, which then precipitate and deposit from the solution system. In terms of physical properties, the viscosity of their solutions is usually high, especially in low temperature environments or at high concentrations, the fluidity is significantly reduced, which further aggravates the occurrence of deposition.

[0003] Based on the above, the existing quantitative delivery system of anti-deposition wet strength agent has the following shortcomings:

[0004] In the storage stage, most conventional storage tanks only have a simple static function and lack an effective internal stirring or disturbance mechanism. As a result, the wet strength agent concentration in the bottom area gradually increases due to the influence of gravity during the long-term static process, and the molecular aggregation phenomenon becomes more serious, eventually forming a hard precipitation layer. These precipitations will not only lead to the loss of effective ingredients of the wet strength agent and reduce its utilization rate, but also cause blockage risks to the bottom structure and outlet pipeline of the storage tank, increasing the difficulty and cost of equipment maintenance; in the transportation process, the disadvantages of the traditional transportation system are more prominent. Due to the lack of pretreatment measures specifically targeting the deposition characteristics of the wet strength agent, when the wet strength agent flows in the pipeline, the friction with the pipe wall and the change in flow rate may cause it to deposit. Once deposition occurs, the inner diameter of the pipeline will gradually decrease, and the fluid resistance will increase accordingly. This will not only affect the stable transportation of the wet strength agent and cause fluctuations in the transportation flow, but may also cause pipeline blockage, forcing the entire transportation system to shut down. Cleaning and maintenance, this downtime event not only consumes a lot of manpower, material and time resources, but also seriously interrupts the papermaking production process, resulting in a significant reduction in production efficiency and a sharp increase in production costs; with the continuous development of papermaking technology, different paper varieties and production processes have extremely strict control standards for the amount of wet strength agent added, and the error range is usually required to be within a very small range. However, the metering equipment and control means used in traditional conveying systems are relatively simple, and it is difficult to accurately adjust the delivery amount of wet strength agent. For example, some conveying systems based on simple mechanical pumps and rough flow control valves have limited stroke accuracy of mechanical pumps and low control sensitivity of flow control valves. When facing different papermaking machine speeds, paper weights and changes in wet strength agent concentrations, it is impossible to adjust the delivery amount in a timely and accurate manner, resulting in fluctuations in paper quality, such as insufficient or excessive wet strength, which affects the physical properties and printing adaptability of the paper, thereby reducing the market competitiveness of the product. Summary of the invention

[0005] The disclosed embodiment relates to a quantitative conveying system for an anti-deposition wet strength agent, which drives a driving worm to rotate through an anti-deposition motor, and the driving worm drives an anti-deposition turntable to rotate through meshing with a transmission worm wheel. When the anti-deposition turntable rotates, an anti-deposition lever on the top of the anti-deposition turntable will stir the bottom of the storage tank, thereby preventing the wet strength agent from being deposited due to long-term storage, and when the anti-deposition turntable rotates, the wet strength agent will be pushed to a reflux port opened at the bottom of the inner wall of the storage tank, and the wet strength agent will be impacted from the reflux port to the top of the anti-deposition turntable through a pipe connected to the reflux port and the reflux outlet, thereby preventing the negative pressure area between adjacent anti-deposition levers on the top of the anti-deposition turntable from causing wet strength agent deposition, destroying the aggregation structure between wet strength agent molecules, keeping the wet strength agent in a dispersed state, and effectively preventing deposition in the storage tank. A heating ring cavity is provided in the middle of an outer conveying pipe of the storage tank, thereby appropriately heating the wet strength agent, adjusting the heating temperature according to the characteristics of the wet strength agent, so as to reduce its viscosity, further reducing the possibility of deposition, and conveying the wet strength agent through a spiral conveying rod connected to the conveying motor. Operation, while controlling the flow rate of the wet strength agent, prolonging the heating time of the wet strength agent, can prevent impurities from clogging the external delivery pipe, and reduce the impact on the quantitative delivery accuracy. By arranging a heating ring cavity in the middle of the external delivery pipe of the storage tank, the wet strength agent is moderately heated, and the heating temperature is adjusted according to the characteristics of the wet strength agent to reduce its viscosity, further reducing the possibility of deposition, and the wet strength agent is conveyed by a spiral conveying rod connected to a conveying motor. While controlling the flow rate of the wet strength agent, the heating time of the wet strength agent is prolonged, which can prevent impurities from clogging the external delivery pipe and reduce the impact on the quantitative delivery accuracy. The delivery flow of the wet strength agent is accurately controlled by a high-precision metering pump, and its flow adjustment range is wide, which can meet the requirements of different papermaking processes for the addition amount of the wet strength agent.
