Reactor for EPS

Abstract

The invention discloses an expandable polystyrene reaction kettle which is quick to regulate the temperature and convenient to clean up, examine and repair. The expandable polystyrene reaction kettle primarily comprises a kettle body on which a thermometer and a pressure gauge are arranged; a frame is arranged at the upper end of the kettle body, and a motor and a decelerator are arranged on the frame; a plurality of blenders are arranged on a blending axle inside the kettle body; at least two detachable blocking pieces are symmetrically arranged inside the kettle body; a spiral semi-circulartube is spirally wound on the external side wall of the kettle body. The expandable polystyrene reaction kettle has the advantages that the expandable polystyrene reaction kettle is low in cost and the raw materials inside the reaction kettle will not adhere to the kettle; both the blocking pieces and the blenders are detachable and are convenient to clean up, examine and repair; meanwhile, the spiral semi-circular tube spirally wound on the external side wall of the kettle body can meet the requirements of raising and lowering the temperature quickly and effectively controlling the temperature inside the kettle during the reaction, thus improving the productive efficiency of the kettle.

Description

Reactor for expandable polystyrene technical field The invention relates to a production equipment of expandable polystyrene, in particular to a reaction kettle for producing expandable polystyrene. Background technique my country's current production of reactors for expandable polystyrene has always relied on imports. The structure of imported reactors for expandable polystyrene mainly includes: a tank body, which is equipped with a thermometer and a pressure gauge. The upper end of the body is also equipped with a frame, which is equipped with a motor and a reducer. The rotating shaft of the reducer is connected with the stirring shaft arranged on the frame through a coupling, and the stirring shaft extends through the opening at the upper end of the tank body. To the inside of the tank body, the opening at the upper end of the tank body is sealed by a mechanical seal, a feed port is set at the upper end of the tank body, a discharge port is set at the bottom of the tank b...

Problems solved by technology

The imported reactor for expandable polystyrene is not only expensive but also has the following disadvantages: the stopper in the reactor for expandable polystyrene of this structure is fixed inside the tank body, and the tank body During the reaction process, the raw materials often have the phenomenon of cascading, especially the cascade body is attached to the inner wall of the tank, which is very difficult to clean and overhaul, causing huge economic losses to the enterprise. In addition, the cooling tank installed on the outer wall of the tank The jacket cannot meet the technological requirements of rapid temperature rise and fall, and cannot effectively control the temperature in the tank during the reaction process, so that the production efficiency of the reactor is not high
