Polystyrene stirring tank with automatic spraying device

Abstract

The invention relates to a device for making EPS extruded boards, in particular to a polystyrene mixing tank with an automatic spraying device, which includes a tank body provided with a material inlet and a material outlet and an automatic spraying device, The feed inlet is set at the bottom of the tank body, and the discharge port is set at the side of the tank body. 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, and a lifting auger at the bottom of the lifting auger. Feeding port, lifting auger The feeding port is located at the lowest point of the bottom of the tank, and the top of the lifting auger is equipped with an arc-shaped discharge surface. The automatic spraying device includes a humidity sensor and a nozzle. The humidity sensor controls the nozzle. The fan is connected with the silo, and the outlet is equipped with a protective screen. The device provided by the invention has simple structure and convenient operation, which is beneficial to prolonging the suspension time of polystyrene particles in the tank, making the spraying and mixing more uniform, and realizing automatic control of the humidity in the tank.

Description

[0001] The invention relates to a device for making EPS extruded boards, in particular to a polystyrene mixing tank with an automatic spraying device. Background technique [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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device with simple structure, convenient operation and high efficiency, which is beneficial to prolong the sus...
