Problems solved by technology

[0003] In the process of production and preparation of expanded polystyrene, it is often necessary to foam the mixed slurry. The foaming operation of polystyrene production is generally heat-treated by heating. The usual heating and foaming treatment in the prior art , heat treatment is carried out in a small range of fixed points, and the slurry distributed in the vertical direction is often heated unevenly. During the long-term heating treatment process, local overheating often results in damage to the material and affects the actual Foaming effect

Abstract

The invention belongs to the technical field of polystyrene, and particularly relates to polystyrene production equipment. The following scheme is provided. The polystyrene production equipment comprises a foaming box, sealing covers are detachably connected to the two ends of the foaming box, and a heat exchange pipe is fixed to the middle position between the inner wall of the top and the inner wall of the bottom of the foaming box; a ventilation pipe is fixed to the position, located in the center of the heat exchange pipe, of the inner wall of the top of the foaming box, an air inlet pipe is connected to the top end of the ventilation pipe, a connecting net cylinder is connected between the bottom end of the ventilation pipe and the inner wall of the bottom of the foaming box, and a vertically-arranged first spring is fixed to the position, located in the center of the connecting net cylinder, of the inner wall of the bottom of the foaming box; and a first piston piece slidably connected with the inner wall of the ventilation pipe is fixed to the top end of the first spring. According to the invention, a large amount of high temperature in the ventilation cavity is wholly rushed out and quickly dispersed to all positions of the heat exchange cavity from the connecting net cylinder so that heat in the heat exchange pipe in the vertical direction is quickly and uniformly distributed, and slurry in the foaming box is heated and foamed.

Description

technical field [0001] The invention relates to the technical field of polystyrene, in particular to a polystyrene production equipment. Background technique [0002] Polystyrene belongs to polyolefin, which is formed by free radical polymerization of styrene. Polystyrene is a widely used brittle plastic. Expanded polystyrene, also known as expandable polystyrene, has a small relative density. , low thermal conductivity, small water absorption, impact vibration resistance, heat insulation, sound insulation, moisture resistance, vibration reduction, excellent dielectric properties, etc., widely used in mechanical equipment, instruments, household appliances, handicrafts and other fragile and precious Shockproof packaging materials for products and packaging for fast food. [0003] In the process of production and preparation of expanded polystyrene, it is often necessary to foam the mixed slurry. The foaming operation of polystyrene production is generally heat-treated by he...
