Automatic devulcanizing and plasticizing device and method for waste rubber powder

Abstract

The invention provides automatic devulcanizing and plasticizing device and method for waste rubber powder. In the automatic devulcanizing and plasticizing device, a plastic highly stirring machine is applied to the automatic devulcanizing and plasticizing device for the waste rubber powder, which can realize high-speed stirring, enable ingredients to be mixed sufficiently and uniformly and realize the bulking, the immersing and the swelling of raw materials; a thermal reaction device comprises single or a plurality of plasticizing units; each screw material rod of a double-screw conveying device inside the thermal reaction device feeds by adopting differential motion; and if the thermal reaction device comprises a plurality of plasticizing units, the plasticizing units are arranged in a vertical spacing way, and each plasticizing unit is provided with an independent heating device which has short heating time and ensures the reaction to be sufficient. Because each screw material rod feeds by adopting the differential motion, the screw material rods are enabled to have self-cleaning function; meanwhile, the plasticizing units adopt a modular design, which enables the plasticizing units to be freely collated according to the different requirements of users on devulcanizing depth, thereby fully reducing equipment manufacturing cost and product production cost; and because of the adoption of a vertical spacing distribution structure, the equipment can be both expanded and conveniently maintained and overhauled.

Description

technical field [0001] The invention relates to an automatic sulfur breaking plasticizing device for plasticizing waste rubber powder in the field of waste rubber recycling and processing, and also relates to a plasticizing method for automatically breaking sulfur of waste rubber powder. Background technique [0002] At present, there are two main ways to apply vulcanized rubber powder from waste tires: one is to directly make vulcanized rubber powder into various products or add it to other materials to mix and process it into various products or applications; the other is to process vulcanized rubber powder into Reclaimed rubber that can be vulcanized again to replace virgin rubber in products. [0003] Due to the increasing scarcity of natural resources, the market for reclaimed rubber is growing, and the main link in the production of reclaimed rubber is the plasticization process of vulcanized rubber. Previously, the vulcanized rubber powder desulfurization and plastic...
