Plastic foam particle laminating dryer

Abstract

A plastic foam particle laminating dryer comprises a rack. A laminating box is arranged on the rack. A stirring device is arranged in the laminating box. The stirring device is driven by a servo motor arranged on the rack. A storage box and a spraying device used for spraying fire retardant and a curing agent to particles in the laminating box are arranged above the laminating box. The rack is further provided with a drying box connected with the laminating box and used for drying the laminated particles, heat exchangers connected with the drying box and used for supplying heat to the drying box, and an induced draught fan used for performing impurity removing and screening on the dried particles. The heat exchangers are driven by an air blower. The plastic foam particle laminating dryer further comprises a metering weighing device connected with the storage box. Particles in the metering weighing device are conveyed to the storage box through a draught fan. The servo motor, the spraying device, the induced draught fan, the air blower, the draught fan and the metering weighing device are controlled by a control system through signals. The plastic foam particle laminating dryer is high in automation degree, even in adding and capable of effectively screening caked clusters, and disengaging is avoided after adding.

Description

technical field [0001] The invention relates to the technical field of foam processing machinery, in particular to a film-coated dryer for plastic foam particles. Background technique [0002] Plastic foam is a polymer material with plastic as the basic component and contains a large number of bubbles. Therefore, it can also be said to be a composite plastic filled with gas. Compared with pure plastic, it has many excellent properties, such as light weight and specific strength. High, can absorb impact load, good heat insulation and sound insulation performance, etc., so it has been widely used in industry, agriculture, construction, transportation and other fields. However, foam plastics have certain flammability, so it is necessary to add flame retardants to foam plastics to achieve flame retardant effects. The traditional way is to apply flame retardants on the surface to ensure that the flame retardant effect is not good, and It is easy to fall off, and the existing add...

Problems solved by technology

However, foam plastics have certain flammability, so it is necessary to add flame retardants to foam plastics to achieve flame retardant effects. The traditional way is to apply flame retardants on the surface to ensure that the flame retardant effect is not good, and It is easy to fall off, and the existing adding method has uneven addition of particles, and when the additives are attached to the particles, they will stick together and cause agglomeration, which cannot be cleaned effectively, which will affect the later processing
