Double-layer polystyrene curing bin

Abstract

The invention relates to a device for manufacturing an EPS extruded plate, in particular to a double-layer polystyrene curing bin. The double-layer polystyrene curing bin comprises a supporting rack and bin bodies arranged on the supporting rack. The multiple bin bodies are arranged side by side. Each bin body comprises a bin body rack, an interior ventilation screen and a top ventilation screen, the interior ventilation screen and the top ventilation screen are connected to the bin body rack in a hung mode, and the interior ventilation screen comprises an upper layer and a lower layer; a material inlet is formed in the upper portion of the upper interior ventilation screen layer and is connected with a material inlet induced draft fan, an upper layer discharge outlet is formed in the bottom of the upper interior ventilation screen layer, a timer is arranged at the upper layer discharge outlet, and the timer control end is connected with a control valve; and a lower layer discharge outlet is formed in the bottom of the lower interior ventilation screen layer, a timer is arranged at the lower layer discharge outlet, and the timer control end is connected with a control valve and a discharge outlet induced draft fan. The device provided by the invention is simple in structure, convenient to operate, small in occupied space, low in cost and high in efficiency, materials can be effectively prevented from flying away, swelling stress can be further buffered and released, and the curing time can be better controlled.

Description

technical field [0001] The invention relates to a device for making EPS extruded boards, in particular to a double-layer polystyrene curing bin. Background technique [0002] The general production of EPS extruded board is mainly made of polystyrene resin as raw material, supplemented by adding a catalyst in the process of heating and mixing the polymer and foaming. The foaming ratio of polystyrene is generally dozens or even hundreds of times, and The curing time needs at least ten hours. The material is easy to fly and has a large expansion stress. Usually, a large curing bin is required, but the curing time of the materials entering the curing bin will vary greatly, and the curing time is also difficult. Control, if you set up multiple curing bins, it will increase the cost and occupy a relatively large area. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-layered product with simple structure, conve...
