Abstract

The invention relates to a kneader-type gel drier for removing light solvent oil in the process of synthesizing rubber. The kneader-type gel drier comprises an upper kneader body and a lower kneader body, wherein an upper kneader surface is arranged on the bottom of the upper kneader body, and a lower kneader surface is arranged on the top of the lower kneader body. The upper kneader surface is opposite to the lower kneader surface. The lower kneader body has a constant temperature liquor inlet and a constant temperature liquor outlet which are connected with a constant temperature water bathheater or a constant temperature oil bath heater. A glue liquor inlet, a glue liquor passage and a glue liquor outlet are also provided. A shaft fixed on the upper part of the upper kneader body is connected with a driving device which makes the shaft drive the upper kneader body to swing, translate or rotate, thereby producing the relative movement between the upper kneader surface and the lowerkneader surface. The kneader type gel drier has the advantages that the two kneader surfaces move relatively so as to heat and knead the glue liquor continuously flowing in; therefore, the light solvent oil in the glue liquor is heated and evaporated and the glue liquor is gradually turned into dry gel. The kneader-type gel drier opens up a new way to remove the light solvent oil in the process of synthesizing rubber.

Description

technical field [0001] The invention relates to the technical field of synthetic rubber, in particular to a device for removing light solvent oil used in the synthetic rubber process. Background technique [0002] In the synthetic rubber industry, the glue obtained from the polymerization kettle contains more than 80% light solvent oil, which needs to be removed to obtain dry raw rubber products. The solvent oil removal methods that people have used for a long time are mainly divided into wet coagulation and dry coagulation. [0003] The wet coagulation method refers to that in the coagulation kettle, the glue is put into boiling water and cooked with high-temperature steam, and most of the low-boiling solvents are volatilized, and then squeezed and dried on the extrusion dehydrator and expansion dryer. High temperature (180°C) expansion and other processes remove the remaining solvent oil and the water entrained in the boiling process, and finally get the dried finished ra...
