Problems solved by technology

[0002] The production of EPS extruded board is mainly made of polystyrene resin as raw material, supplemented by polymer and catalyst for mixing, stirring and foaming, and the polystyrene mixing tank is usually equipped with an inlet at the upper part and an outlet at the lower part. Due to the weight of the object, this kind of setting makes the material fall to the bottom of the tank quickly, which is easy to cause uneven spraying, and the humidity is not easy to control, which is not conducive to the mixing and foaming of the material, and will increase the spraying and stirring time. After mixing and foaming, polystyrene becomes granules with very small density. It is easy to fly after being released from the mixing tank, and has a large expansion stress. Usually, the closed warehouse is made of iron sheet to prevent the material from flying. But it cannot buffer the expansion stress, the cost is high, the weight is heavy, and it is not easy to observe the material situation in the warehouse

Abstract

The invention relates to a device for making EPS extruded boards, in particular to a polystyrene mixed buffer system, which includes a tank body, an automatic spray device and a blanking bin, and the bottom surface of the tank body is a slope structure with high surroundings and low middle , There is a lifting auger in the middle of the tank body, an arc-shaped discharge surface is provided on the top of the lifting auger, and the nozzle of the automatic spraying device is set directly above the arc-shaped discharge surface. The humidity sensor controls the nozzle, and the discharge port of the tank is set. There is a protective screen. The blanking bin includes a buffer bin and an inlet bin. The buffer bin is equipped with a protective screen and an observation window. The gas dispersion chamber communicated with the blower. The device provided by the invention is beneficial to prolong the suspension time of polystyrene particles in the tank, make the spraying and mixing more uniform, realize automatic control of the humidity in the tank, and effectively prevent materials from flying and buffer expansion stress.
