Polymerization device for butyronitrile latex production

Abstract

The invention discloses a polymerization device for butyronitrile latex production, which comprises a kettle body, a pipe frame and a support frame, a jacket is mounted on the outer side of the kettle body, a support shaft is mounted between the kettle body and the jacket, an impeller is connected to the support shaft, an air inlet pipe is mounted on one side of the jacket, and a water inlet pipe is mounted on the other side of the jacket. The reaction kettle has the beneficial effects that by arranging the connecting pipe, the pipe frame and the spray head, the connecting pipe can be connected with external pressurizing equipment, then high-pressure gas is conveyed to the spray head through the pipe frame, and the spray head blows the high-pressure gas into the kettle body, so that the flowing speed of materials can be increased, materials adhered to the inner wall of the kettle body can be blown, and the reaction kettle is convenient to use and high in practicability. By arranging a sampling pipe and an electromagnetic valve II, the on-off of the sampling pipe can be controlled through the electromagnetic valve II, so that a worker can conveniently use the sampling pipe to sample and observe the material in the polymerization process, and the reaction degree of the material is accurately mastered.

Description

technical field [0001] The invention relates to the technical field of a polymerization device for the production of nitrile latex, in particular to a polymerization device for the production of nitrile latex. Background technique [0002] Nitrile latex is the latex prepared by the emulsion polymerization of butadiene and acrylonitrile. In the production process of nitrile latex, a polymerization kettle is required, and the polymerization kettle is the main equipment for preparing polymer compounds. It is generally a vertical cylindrical autoclave. Jacketed for heating or cooling with steam or cold water. [0003] During the use of the existing polymerization device for the production of nitrile latex, the material after polymerization is discharged from the kettle body through the discharge pipe, and when discharged, the flow rate of the material is relatively slow, resulting in a long discharge time and inconvenient use , reduce the practicability of the device. In additi...

Problems solved by technology

[0003] During the use of the existing polymerization device for the production of nitrile latex, the material after polymerization is discharged from the kettle body through the discharge pipe, and when discharged, the flow rate of the material is relatively slow, resulting in a long discharge time and inconvenient use , reduce the practicability of the device. In addition, during the use of the existing polymerization device for the production of nitrile latex, the polymerization kettle adopts a sealed structure, which is not convenient for the staff to sample and observe the material during the polymerization process. In addition, the existing nitrile latex During the use of the polymerization device for latex production, heating or cooling is carried out by sending steam or cold water into the jacket, and the steam or cold water moves by its own fluidity, and the moving speed is slow, which increases the heating or cooling time of the kettle body and reduces device efficiency
