A waste tire cracking and discharging process and equipment

Abstract

A process and apparatus for scrap tire pyrolysis and material discharging. The apparatus comprises a material chamber (1). A material-discharging mechanism, a sealing apparatus, and a baffle (14) are arranged in the material chamber (1). The material-discharging mechanism comprises sequentially from outside to inside a drum (2), turntables (3), and an eccentric shaft. A rotary sleeve (4) is provided between the turntables (3) and the eccentric shaft. The eccentric shaft is constituted by shaft I (5) and shaft II (6) that are integrally arranged. The axis of shaft I (5) is located above the axis of shaft II (6). The drum is concentric with shaft I (5). The turntables (3) are sleevedly connected onto both ends shaft II (6) and are concentric with shaft II (6). An opening is provided on the drum (2). Connecting rods (8) are provided on the turntables (3). A telescopic rod set movably embedded into the opening is provided between two turntable connecting rods (8). The sealing apparatus is connected to the bottom extremity of the baffle (14). The sealing apparatus and the baffle (14) are arranged at where the telescopic rod is shortest on an outer barrel. By employing interactions of an eccentric structure and a sealing structure, implemented is whole-tire continuous pyrolysis and material discharging in a sealed state, thus providing a novel approach for scrap tire pyrolysis.

Description

technical field [0001] The invention relates to the field of chemical industry, and specifically provides a waste tire cracking and discharging process and equipment. Background technique [0002] As we all know, gasoline, diesel, carbon black and other products can be obtained after cracking waste rubber, which not only finds a good solution for the disposal of waste tires produced in large quantities in modern society, but also provides a new solution for resource reduction and energy shortage improvement. However, at present, all the cracking of waste rubber is to break the waste rubber into small pieces before cracking. During the production process, additional tire crushing equipment needs to be prepared, which virtually increases the production cost and production process. Therefore, the cracking of the whole tire becomes waste The inevitable trend of tire cracking, however, because the iron wire produced after the whole tire cracking is whole, with ash or other uncrac...

However, at present, all the cracking of waste rubber is to break the waste rubber into small pieces before cracking. During the production process, additional tire crushing equipment needs to be prepared, which virtually increases the production cost and production process. Therefore, the cracking of the whole tire becomes waste The inevitable trend of tire cracking, however, because the iron wire produced after the whole tire is cracked is whole, with ash or other uncracked components attached to it, making it difficult to discharge the material, and the existing discharge equipment is helpless
