Problems solved by technology
Whether it is a single helix or a double helix, the quality of the product is unstable; the plasticizing temperature is high, reaching 270°C-330°C, and the energy consumption is high. Although reclaimed rubber is produced; but the production temperature is high, the energy consumption is high, and there is a small amount of exhaust gas emission. Unstable quality and low production efficiency

The invention discloses an intelligent environment-friendly constant-pressure medium-temperature fast rubber plasticizing unit, wherein the outlet of a pre-treatment tank is connected with an airtight storage tank installed on a frame, the outlet of the airtight storage tank connected with a vacuum feeding device driven by a motor is connected with a feed inlet of a waste rubber friction plasticizing reaction kettle through an airtight feeding valve, heating oil is arranged in an interlayer of the tank body of the reaction kettle, the material outlet of the reaction kettle is connected with a cooling tank through the airtight feeding valve, and air outlets uniformly distributed on the upper tank body of the cooling tank are respectively connected with a first-level exhaust treatment tank and a second-level exhaust treatment tank. The outlet at the top of the first-level exhaust treatment tank is connected with the inlet of the side wall of the second-level exhaust treatment tank through a pipeline, the outlet of the second-level exhaust treatment tank is connected with a third-level exhaust treatment tank, and the material outlet at the lower part of the cooling tank is connected with a cooling screw conveyer through the airtight feeding valve. Regenerated rubber is produced in a totally airtight condition in a dry state without wastewater and exhaust gas, so that the unit is high in production efficiency, energy-saving and environment-friendly.
Description
Technical field [0001] The invention belongs to equipment for producing reclaimed rubber, in particular to an intelligent and environmentally friendly normal pressure and medium temperature rapid rubber plasticizing unit. Background technique [0002] At present, some enterprises in our country adopt the dynamic method to produce reclaimed rubber. Although it can produce high-quality reclaimed rubber, it has high temperature, high pressure, high energy consumption, a large amount of exhaust gas emissions, secondary pollution, high pressure and unsafe. The normal pressure plasticization method used in recent years has solved the high pressure problem, but the product quality is unstable, the Mooney rebounds quickly, the reclaimed rubber is hard, the process performance is not good, and it needs high temperature, high energy consumption, low output , Equipment manufacturing lags behind and cannot meet the requirements of new processes. The normal pressure plasticization method is...
