Thermal regeneration device for waste rubber and thermal regeneration method thereof

Abstract

The invention discloses a thermal regeneration device for waste rubber and a thermal regeneration method thereof, belonging to the technical field of regeneration processing and utilization of waste rubber. The thermal regeneration device comprises: a base, wherein supporting legs are arranged at four corners of the bottom of the base; a stirring barrel, which is arranged on the upper side of thebase, wherein a plurality of T-shaped rotating supporting rods which are uniformly distributed are arranged at the bottom of the stirring barrel, a feeding hole is formed in the top of the stirring barrel, a sealing cover plate is arranged on the feeding hole, a discharging hole is formed in the lower left corner of the end part of the stirring barrel, and a discharging valve is arranged on the discharging hole; an annular T-shaped limiting rotating groove, which is formed in the top of the base, wherein the T-shaped ends of the T-shaped rotating supporting rods are arranged on the inner wallof the annular T-shaped limiting rotating groove in a sliding mode; and a first transmission mechanism, which is arranged on the top of the base and located at the left side of the stirring barrel. According to the stirring device, nitrogen is recycled and changed into liquid nitrogen for realizing better cooling, a conception is ingenious, stirring and heating effect is extremely good, and the device has outstanding substantive features and remarkable progress.

Description

technical field [0001] The invention relates to the technical field of recycling processing and utilization of waste rubber, and more specifically relates to a waste rubber heat regeneration device and a heat regeneration method thereof. Background technique [0002] Today is an era that emphasizes circular economy and sustainable development. The recycling of waste rubber should be necessary for my country, a country with poor rubber resources and serious environmental pollution, to practice circular economy and sustainable development, and to carry out economic construction and national rejuvenation. Focusing on the development of the Sunshine Industry, but due to the immature development of waste tire rubber regeneration technology that exceeds 60% of the total waste rubber, especially for the preparation of regenerated rubber from waste tires through crushing, separation, high-temperature sulfur breaking, etc. Technology, that is, the so-called "thermal regeneration" techn...

Problems solved by technology

[0012] The authorized publication number "CN102030934B" records "a method for thermal regeneration of waste rubber, which is to make the weight ratio of "waste rubber coarse powder / environmentally friendly softener / powder auxiliary material" in the range of 100 / 8-150 / 20-1500 The raw materials are put into the stirring heater, heated by anaerobic first, then introduced into the stirring cooler, cooled to below 100°C, and the product is obtained; Before the material that enters the stirring heater is discharged, add the powder auxiliary material deducted first into the stirring heater, or / and add it when the hot material is introduced into the stirring cooler, and wait until the mixture is cooled to below 100°C. discharge; or introduce the formula into the screw extruder after initial mixing, and after overheating and mixing, cool the material to 100°C to obtain the product; or regenerate the heat, and the known The thermal cracking of waste rubber, or the process of preparing carbon black from combustible fuel and combustible gas, establishes a multi-directional transfer relationship of materials or / and energy", and in the process of anaerobic heating in this method, nitrogen gas It can be realized, but after the nitrogen is blown in, there is no good circulation, so that the nitrogen cannot be fully utilized, and the subsequent cooling is performed separately. How to recycle nitrogen and its physical characteristics for cooling is what we need The problem to be solved is that the stirring and heating effect of the above-mentioned patented stirring heater is not ideal
