Oven dry process for nature rubber

Abstract

The invention discloses a drying process of natural rubber, and relates to the deep-processing technical filed of natural rubber, in particular to a natural rubber drying process which dries by steam and can reduce cost, potential safety hazard and pollution. The drying process of the natural rubber comprises procedures of dehumidifying, drying by a two-stage drying system and cooling to dry the natural rubber, and the process is characterized in that the two-stage drying system dries the natural rubber by heat exchange of saturated steam. The natural rubber dried by the process has greatly enhanced heat source utilization rate. Compared with the fuel drying process and equipment in the present natural rubber processing field, the process can better control temperature stability, fully protect and enhance physical and chemical property indexes of the natural rubber, reduce rubber drying cost, and reduce fire risk.

Description

technical field

[0001] The invention relates to the technical field of natural rubber deep processing, in particular to a natural rubber drying process using steam for drying, which can reduce costs, reduce potential safety hazards and reduce pollution. Background technique

[0002] Rubber, steel, petroleum, and coal are known as the four major industrial raw materials. Rubber products are widely used in various fields of the national economy due to their high elasticity and high air tightness. Among them, tires are the leading products in the rubber processing industry, and their rubber consumption accounts for more than 70% of the total rubber consumption of rubber products. Radial tire is an updated product of the tire industry. It has the advantages of safe driving, low rolling resistance, fuel saving and wear resistance, so it is developing rapidly in all countries in the world. Natural rubber is the key raw material for the production of radial tires, which determine...

[0026] Example 1: A drying process for natural rubber with a design capacity of 5 tons / hour. First, the crushed natural rubber with a particularly high moisture content is dried by a suction fan to take away most of the moisture in the rubber material , and then enter the first-stage drying system, and the steam with a temperature of 100 ° C is transported from the steam pipe into the heat exchanger of the drying system; the surrounding air is heated through the heat exchanger to form hot air, and the hot air is drawn by the fan It flows in the opposite direction to the rubber material in the drying furnace; the moisture on the surface of the raw material is taken away by the hot air flow, and the raw material is cooked, and the hot air is transformed into a wet and cold air; the wet and cold air is drawn by the induced draft fan installed at the feed inlet It is led away and discharged from the exhaust gas treatment tower. After the first-stage drying system, most of the raw ...
