Automatic separation method and equipment for solid phase products of continuous pyrolysis of waste tire whole tire industry

Abstract

The invention discloses a method and equipment for automatic separation of solid phase products of continuous cracking of waste tire industry, including a special-shaped double-cone continuous feeding system connected by connecting parts, a cracking reactor main system, a separation system of cracking solid phase products, and steel wires. Conveying system, pyrolysis carbon black continuous output system, pyrolysis oil level automatic collection system, modular distributed intelligent tail gas comprehensive treatment system, pyrolysis non-condensable combustible gas recycling system, combustion heating system and catalytic cracking intelligent control system; cracking solid The phase product separation system includes a solid phase product separation blade and a steel wire conveying blade structure. There is a baffle between the solid phase product separation blade and the steel wire conveying blade, so that the cracked steel wire must cross the middle baffle during the conveying process; the solid phase product separation During the conveying process of the blades, the cracked steel wire clusters are always in the rolling process, so that the carbon black mixed in the cracked steel wires gradually leaks out. The invention solves the problem of low efficiency in the prior art and has high reliability.

Description

technical field [0001] The invention belongs to the technical field of solid waste recycling, and is oriented to the waste tire resource utilization industry, especially the continuous cracking of the waste tire whole tire industry. The separation, transportation method and device of cracked steel wire and cracked carbon black can realize continuous whole tire cracking in waste tire industry and save energy consumption in the cracking process. Background technique [0002] Rubber is an important strategic material related to the national economy and people's livelihood and national defense security. It is also known as the four basic industrial raw materials together with coal, steel and oil. It is widely used in various fields such as industry, agriculture, national defense, aerospace, transportation, and daily production. With the strong support of national policies, the rubber industry has become the main supporting industry of the national economy, with an annual domesti...

Problems solved by technology

According to the search information on waste tire cracking patents, the current cracking of waste tires is mainly based on intermittent cracking and waste tire crushing cracking. Among them, the intermittent cracking has low cracking efficiency, high labor intensity and relatively low level of intelligence. Low-level problems, the industry does not encourage the development of intermittent cracking technology; waste tire crushing cracking requires additional tire shredders, which increases the waste tire cracking process and energy consumption; therefore, waste tire cracking has become an industry The trend of development, but has not seen industrial application, this is mainly due to the small size of steel wire in the solid phase product of waste tire crushing continuous cracking, which can be transported out of the cracking reactor through the carbon black output device together with cracking carbon black, After the magnetic separation process, they can be separated from each other; while the tire belt layer and the steel wire in the carcass remain intact during the continuous cracking process of the whole waste tire, the traditional separation, transportation methods and devices cannot complete the separation of the steel wire and the pyrolysis carbon black. And transportation, which is also one of the main problems that the whole tire continuous cracking equipment has not appeared in the industry.
