The working process of the internal rotation type waste rubber and plastic thermal cracking equipment comprises the following steps:
the materials enter the first reaction kettle 1 and the second reaction kettle 2 in sequence for high-temperature thermal cracking, during the high-temperature thermal cracking, when the kettle bodies on the left side and the right side are raised to expand towards the middle line, the corrugated compensator 31 is extruded to contract towards the middle, and push rods of the cylinders 35 on the left side and the right side push the tension springs 37 in the spring sleeve 36 to compress; on the contrary, when the left and right kettle bodies shrink due to temperature decrease, the ripple compensator 31 is driven to extend, and since the kettle body generally has a large friction force during shrinkage, the ripple compensator 31 is prevented from being torn, the ripple compensator 31 is not enough to safely displace due to the tension of the tension spring 37, and at this time, the ripple compensator 31 needs to be assisted by the cylinders 35 on both sides to ensure that the ripple compensator 31 stretches according to the set technical parameters.
The reation kettle of above-mentioned equipment adopts multi-stage construction, can increase the module wantonly, and increase of production adopts internal rotation propulsion mode, has avoided the accumulation of the internal material of cauldron to and the drawback of cauldron internal wall coking, prolonged the life of equipment, compares with outer formula thermal cracking equipment of revolving, has reduced the sealed sealing device of the front-and-back dynamic static, and equipment can adopt the malleation operation, has avoided the leakage risk of oil steam.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
