Polystyrene receiving bin

Abstract

The invention relates to a device for manufacturing an EPS extruded sheet, in particular to a polystyrene receiving bin. The polystyrene receiving bin comprises a protective screen for a discharge hole of a stirring tank, a buffer bin and a charge bin which is arranged in an extending direction of the buffer bin and mutually communicates with the buffer bin, wherein the buffer bin comprises a buffer bin bottom plate, a buffer bin upper protective screen, protective screens on two side surfaces of the buffer bin and a buffer bin observation window arranged at one end opposite to the charge bin; a receiving hole of the protective screen for the discharge hole of the stirring tank is formed in the upper portion of the buffer bin upper protective screen, and communicates with a bin body; the buffer bin bottom plate is provided with gas ventilating slots which are inclined towards the charge bin; a gas dispersing cavity is formed below the buffer bin bottom plate; and the gas dispersing cavity communicates with an air blower. The polystyrene receiving bin provided by the invention is simple in structure, is convenient to operate, is low in manufacturing cost, is light in weight, can effectively prevent materials from floating to relieve expansion stress of the materials, and is convenient for a user to observe a material condition in the receiving bin.

Description

[0001] The invention relates to a device for making EPS extruded boards, in particular to a polystyrene blanking bin. Background technique [0002] The production of EPS extruded board is mainly made of polystyrene resin as raw material, supplemented with polymer and catalyst for mixing, stirring and foaming. After mixing, stirring and foaming, polystyrene becomes granular with very small density and released from the mixing tank. When it comes out, the prestress is very large, and it is very easy to fly away. Usually, a closed fence structure made of iron sheet is used to prevent the material from flying away, but it cannot buffer the expansion stress of the material, and the cost is high, the weight is heavy, and the inside of the warehouse cannot be seen. Material condition. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a polystyrene blanking bin with simple structure, convenient operation, which can effective...
