Central flow dividing type one-step rubber fining process and system

Abstract

The invention discloses a central flow dividing type one-step rubber fining process and system. In the invention, a rubber fining process with an internal mixer, a central open mill and a plurality of parallel open mills is adopted; after rubber materials are mixed and discharged, the rubber materials enter the central open mill and cooled by the central open mill, and then the master batch of a vulcanizing agent is added; then, the rubber materials enter a rubber material dividing and delivery system and assigned to a plurality of surrounding target open mills for further rubber fining, wherein the rubber fining time of each target open mill can be four times as long as the mixing time so as to guarantee the effect of uniform rubber fining; after four open mills discharge rubber, the discharged rubber materials enter a rubber material convergence and delivery system through a rubber material collecting system; and then a rubber slice cooling system is used for cooling and dischargingrubber slices so as to finish the whole rubber fining process. The process benefits the reduction of the floor area of a plant, the occupation area of equipment and the number of worker and the greatimprovement of the rubber fining quality and the rubber fining productivity so as to achieve the purposes of high quality, high efficiency, energy saving, low carbon and low cost of rubber fining.

Description

technical field [0001] The invention belongs to the technical field of manufacturing tires and other rubber products, and in particular relates to the banburying and mixing process of rubber materials in the manufacturing process of tires and other rubber products. Background technique [0002] The rubber mixing and mixing process is the first link in the production process of rubber products (especially tires). The quality of the rubber mixing effect is directly related to whether the following processes can be carried out smoothly and the final quality of the product. [0003] The rubber mixing process is the process of fully mixing natural rubber, synthetic rubber or other types of rubber with various fillers, plasticizers, anti-aging agents, vulcanizing agents and other chemical additives. In the traditional rubber mixing process, according to the formula and final Due to the different performance requirements of rubber mixing, the order of adding various non-rubber chem...

Problems solved by technology

[0007] The above-mentioned traditional mixing method and system need to put the rubber into the internal mixer for mixing three times repeatedly. After each mixing, it needs to go through steps such as tableting, cooling, and parking. The whole rubber mixing process needs to be parked for more than 24 hours in total, and It requires a large amount of rubber reserves and storage area. To ensure continuous production, it is necessary to equip 3 internal mixers of the same type or 1 large and 1 small 2 internal mixers at the same time. The equipment investment is more than 15 million yuan, and the plant area is about 6,000 square meters. Not only does it take up a lot of public engineering facilities, but it also takes a long time for rubber mixing, takes up a lot of equipment, and consumes a lot of manpower and material resources. It is a very uneconomical rubber mixing process.
