Description

A high-efficient agitating unit of circulation formula for latex silk production Technical Field The invention relates to the technical field of latex yarn production equipment, in particular to a circulating type efficient stirring device for latex yarn production. Background The latex yarn is usually prepared by taking natural latex as a basic raw material, adding a stabilizing system, a vulcanizing system, a filler and other process aids, and then carrying out the procedures of proportioning, filtering, extrusion, molding, cleaning, drying, vulcanizing and the like. The formula and technological data of the disclosed latex thread show that the latex thread precursor liquid is not a single liquid, but a composite system composed of natural latex and various functional components, wherein common components comprise natural latex, potassium hydroxide, oleic acid, zinc oxide, accelerator, sulfur, kaolin, titanium pigment, silicone oil and the like. In the preparation process of the latex yarn precursor liquid, the physical forms and the technological effects of different components are obviously different. For example, components such as KOH, oleic acid and the like are more involved in the stability adjustment of a latex system, inorganic fillers such as kaolin, titanium dioxide, diatomite and the like are more concerned with the dispersion uniformity, the sedimentation resistance and the influence on subsequent mechanical properties, and components of a vulcanization system such as zinc oxide, an accelerator, sulfur and the like are closely related to the uniformity of the formation of a subsequent crosslinked network. The related public researches show that the stability of the natural latex system is closely related to pH, alkaline components and a preservation system, the dispersion effect of the inorganic filler is influenced by the system state, the dispersion condition and the addition mode, and the distribution state of the components of the vulcanization system further influences the mechanical property and the network structure uniformity of the subsequent materials. The prior latex thread pre-liquid stirring equipment mostly adopts a single stirring cavity, a single stirring shaft or a local reinforced stirring mode to finish mixing. Although the mode can realize material mixing to a certain extent, when working conditions of staged addition of various fillers and ingredients are faced, obvious defects still exist that 1) part of fillers or ingredients need to undergo a more sufficient dispersing process after being added, if another ingredient is continuously added when the fillers or ingredients do not reach a more uniform state, the mixing process of the previous stage is often interrupted, a plurality of local high concentration areas exist in a system at the same time, the overall mixing difficulty is increased, 2) inorganic fillers have sedimentation tendency, if the inorganic fillers are only subjected to local disturbance at the bottom or single-cavity overall stirring, the problems that the local stirring range is limited, the materials at the corner area or the bottom area are difficult to continuously enter an effective stirring area are easy to occur, so that dead areas or bottom detention areas are formed, and 3) paths and moments of different materials entering a main stirring area are uncontrollable, so that certain ingredients are easy to stay too long before entering the stirring area, or are directly accumulated in the local areas, and the overall uniform dispersing is unfavorable. Especially in emulsion silk front liquid, if the fillers such as kaolin, titanium dioxide, diatomite and the like are intensively added when the stable state of the emulsion is not established or the previous stage of mixing is not completed, local agglomeration, aggravation of sedimentation or uneven dispersion easily occur, and if the components of the vulcanization system such as zinc oxide, accelerator, sulfur and the like are continuously added when the fillers are not fully dispersed, the inconsistent proportion of the components in different areas in the system can be further caused, and the difficulty of obtaining uniform crosslinked network in the follow-up process is increased. The related publications show that the dispersion state, sedimentation resistance and fluidity of the filler in the latex of the latex yarn can influence the 300% stretching stress, tensile strength, elongation at break and ageing resistance of the latex yarn, and meanwhile, the presulfiding time, the vulcanizing system composition and the auxiliary agent dispersion state in the natural latex system can obviously influence the final mechanical property. Therefore, the latex yarn precursor liquid preparation not only requires stirring, but also requires different ingredients to enter an effective stirring area according to proper time and proper mode and complete staged uniform mixing. Based on the problems, such as di
