Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wet strength agent formulation technology, specifically relating to an anti-flocculation wet strength agent formulation system. Background Technology
[0002] In industries such as papermaking, textiles, hygiene products, and others that require enhanced wet strength of materials, the application of wet strength agents is crucial, especially in the production of automotive filter paper, where higher demands are placed on wet strength agents. A wet strength agent is a chemical additive that significantly improves the strength and durability of materials in a wet state, preventing the material from rapidly losing its original structural strength and integrity upon contact with water.
[0003] Automotive filter paper is characterized by high bulk and high dust holding capacity. Especially during the external coating process, a large amount of lint is generated during the production of the filter paper base. Furthermore, due to its low strength, paper breaks are common. Using wet strength agents to increase the strength of the filter paper base can prevent paper breaks and waste during later coating processes caused by insufficient strength, thus affecting the quality of the final product and production efficiency. However, the use of wet strength agents also has its advantages and disadvantages. Especially in summer, the wet strength agent is relatively viscous and easily flocculates on the inner wall of the system pipes. Over time, it can deteriorate and turn black, forming dark spots on the paper surface through the flow system, affecting the quality of the finished product. Therefore, further improvements are needed in the uniform dispersion and prevention of agglomeration (flocculation) of wet strength agents.
[0004] Traditional methods for preparing wet strength agents often rely on simple stirring and mixing. However, this method is difficult to ensure the uniform distribution of wet strength agent particles in the solution, which can easily lead to agglomeration of wet strength agent particles. Agglomeration not only reduces the effective utilization rate of wet strength agents and affects the wet strength improvement effect of materials, but may also have adverse effects on the normal operation of production equipment, such as clogging pipes and affecting production efficiency.
[0005] Therefore, developing a formulation system that can effectively prevent the agglomeration of wet strength agents and achieve uniform dispersion of wet strength agent particles in solution has become an urgent technical problem to be solved in the field of wet strength agent formulation technology. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide an anti-flocculation wet strength agent preparation system. By rationally designing each preparation tank, the efficiency and stability of the wet strength agent preparation process are improved. At the same time, the internal non-stick cloth ensures the cleanliness of the prepared wet strength agent and reduces the impact of wet strength agent agglomeration on subsequent production.
[0007] The anti-flocculation wet strength agent preparation system of this utility model includes a storage tank and a pure water pipeline. The storage tank is connected to the mixing tank via a transfer pump A. The mixing tank is connected to a transition tank via a transfer pump B. The transition tank is connected to a feeding tank via a transfer pump C. The feeding tank is connected to a filter group. The filter group is connected to the feeding pipeline. The pure water pipeline is connected to the mixing tank. The feeding tank is equipped with a pipeline for returning to the transition tank.
[0008] The conveying pump A is equipped with a pipeline connected to the feeding tank, and the conveying pump A has a pipeline that returns to the storage tank, which is equipped with a level gauge.
[0009] The mixing tank is equipped with a differential pressure level gauge and a liquid concentration monitor. The bottom of the transition tank, the feeding tank, and the mixing tank are all equipped with drain outlets.
[0010] The mixing tank, transition tank, and feeding tank have the same internal structure. The inner side of each tank wall is covered with non-stick cloth, and a stirrer is fixed at the bottom of the tank. The stirrer has two layers of stirring blades. The lower stirring blade is anchor-type, and the upper stirring blade is inclined blade-type. The angle between the upper stirring blade and the horizontal plane is 55°.
[0011] The pure water pipeline is connected to the feeding tank, and both the feeding tank and the transition tank are equipped with differential pressure level gauges and liquid concentration monitors.
[0012] Specifically, the aforementioned anti-flocculation wet strength agent preparation system, during operation, uses a transfer pump A to transport the raw materials from the storage tank to the mixing tank. The top of the mixing tank is connected to a pure water pipeline. A liquid concentration monitor is installed on the mixing tank to monitor the concentration in real time, and a differential pressure gauge controls the liquid volume in the tank. When the liquid in the mixing tank reaches the prepared volume, the valve on the return pipeline connected to the storage tank by the transfer pump A is opened, and the raw materials flow back to the storage tank. At the same time, the liquid in the mixing tank is stirred and mixed, and after reacting for a period of time, it is transported to the transition tank by the transfer pump B, and then to the feeding tank by the transfer pump C. The liquid in the feeding tank is finally transported to the required device through a filter group and a feeding pipeline. The filter group is equipped with two filters, and there are two feeding pipelines, both equipped with flow meters. The filter group and feeding pipelines can be switched at any time according to the actual production situation. During the mixing process, due to the flocculation phenomenon of the wet strength agent, each of the mixing tank, transition tank, and feeding tank is equipped with a stirrer. The stirrer has two layers of stirring blades: the lower stirring blade is anchor-type, and the upper stirring blade is inclined-blade-type. The angle between the upper stirring blade and the horizontal plane is 55°. The combination of the two types of stirring blades ensures that the wet strength agent and pure water are fully mixed, avoiding flocculation caused by uneven mixing, and also ensures the stability of the concentration of the wet strength agent solution in the tank. Each tank has a non-adhesive cloth attached around its inner wall. One side of the non-adhesive cloth is made of a Velcro-like material that can be attached to the tank wall to prevent the wet strength agent system from becoming dirty due to flocculation on the tank wall. When replacing the non-adhesive cloth, it can be simply peeled off. At the same time, in order to ensure the stability of the concentration during the preparation process, liquid concentration monitors and differential pressure level gauges are installed on the mixing tank, transition tank, and feeding tank to achieve real-time monitoring of the concentration at each stage. Finally, the feeding tank is equipped with a pipeline for returning to the transition tank. The delivery pump A and the pure water pipeline are also connected to the feeding tank, which can provide raw materials and pure water when the concentration in the feeding tank changes, so as to achieve rapid concentration control.
[0013] Compared with the prior art, the present invention has the following beneficial effects: The anti-flocculation wet strength agent preparation system of the present invention has a reasonable design for each preparation tank, which improves the efficiency and stability of the wet strength agent preparation process. The non-stick cloth inside each preparation tank ensures the cleanliness of the prepared wet strength agent, and the non-stick cloth is easy to replace and simple to operate. Through the reasonable design of the stirring blade, it is ensured that the wet strength agent can still be stirred evenly and the concentration is stable when the viscosity is high. At the same time, the pipeline design adopts a dual pipeline design, which is reasonable and ensures the stability of the system operation. Attached Figure Description

[0021] The mixing tank 2, transition tank 3, and feeding tank 4 have the same internal configuration. The inner side of each tank wall is covered with non-stick cloth 201, and a stirrer 202 is fixed at the bottom of the tank. The stirrer 202 is equipped with two layers of stirring blades 203. The lower stirring blade 203 is anchored, and the upper stirring blade 203 is inclined. The angle between the upper stirring blade 203 and the horizontal plane is 55°.

[0024] The transition tank 3 is equipped with a differential pressure level gauge 13 and a liquid concentration monitor 12, and a drain outlet 14 is provided at the bottom of the transition tank 3.
[0025] The aforementioned anti-flocculation wet strength agent preparation system, during operation, uses a transfer pump A7 to transport the raw materials from storage tank 1 to batching tank 2. The top of batching tank 2 is connected to a pure water pipeline 10. A liquid concentration monitor 12 is installed on batching tank 2 to monitor the concentration in real time and controls the liquid volume in the tank through a differential pressure gauge. When the liquid in batching tank 2 reaches the preparation volume, the valve of the return pipeline connected to storage tank 1 by transfer pump A7 is opened, and the raw materials flow back to storage tank 1.

Filter group 5 is equipped with two filters, and there are two feeding pipelines 6, both equipped with flow meters. Filter group 5 and feeding pipeline 6 can be switched at any time according to the actual production situation. During the batching process, due to the flocculation phenomenon of the wet strength agent, each of the batching tank 2, transition tank 3, and feeding tank 4 is equipped with a stirrer 202. The stirrer 202 has two layers of stirring blades 203. The lower stirring blade 203 is anchor-type, and the upper stirring blade 203 is inclined blade-type. The angle between the upper stirring blade 203 and the horizontal plane is 55°. The combination of the two types of stirring blades 203 ensures that the wet strength agent and pure water are fully mixed, avoiding flocculation caused by uneven stirring, and also ensures the concentration of the wet strength agent solution in the tank. The concentration is stable; each tank has a non-adhesive cloth 201 attached around its inner wall. One side of the non-adhesive cloth 201 is made of a Velcro-like material, which can be adhered to the tank wall to prevent the wet strength agent system from becoming dirty due to flocculation on the tank wall.
