A kind of post-collection pretreatment method of rubber raw material

Abstract

The present invention relates to a method for pretreatment of rubber raw materials after collection, which uses a pretreatment device for rubber raw materials after collection. The pretreatment device for rubber raw materials after collection includes a filter mechanism and an extrusion mechanism. The filter mechanism The lower end is installed on the existing working ground by sliding fit, and the upper end of the filter collection mechanism is provided with an extrusion mechanism. This invention adopts the design concept of combining multiple filtering structures to carry out pretreatment of rubber raw materials after collection, and the filtration of multiple filtering structures is set. The degree increases in turn, which greatly improves the overall filtration degree of rubber raw materials. At the same time, the extrusion mechanism can realize the function of secondary filtration of rubber raw materials by squeezing the air and the rubber raw materials themselves to generate pressure, and this function can greatly improve the filtration efficiency of rubber raw materials. fineness of filtration.

Description

technical field [0001] The invention relates to the technical field of rubber processing, in particular to a method for preprocessing rubber raw materials after collection. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. After removing the external force, it can return to its original shape. Rubber is a completely amorphous polymer. Its glass The transition temperature is low, and the molecular weight is often large, more than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed after extracting gum from rubber trees, rubber grass and other plants. The processing process of natural rubber It mainly includes basic processes such as latex treatment (filtration purification, mixing, dilution), coagulation, mechanical treatment (dehydration, granulation)...

AI Technical Summary

Problems solved by technology

[0003] 1. The rubber raw material is subjected to less filtration times or the filtering structure with the same degree of filtration is used to filter the rubber raw material, so that the filtering effect of the rubber raw material is low, and at the same time, only the flow force and gravity of the rubber raw material itself can be used to achieve the improvement. The degree of filtering is less effective;

[0004] 2. The structure of the filter rubber is easy to adhere to the surface of the rubber material during the working cycle. When the rubber material adheres to a certain extent, it is easy to cause blockage of the filter structure, and the filtered impurities cannot be cleaned effectively and in time. Under the circumstances, it will also lead to the reduction of the filtering effect of the filtering structure
