Problems solved by technology

Insufficient dehydration in the dehydration tank, the particles need to be further dried, which increases the production cost
The traditional dehydration method is manual dehydration without the production line. This dehydration method makes the entire production process unable to operate continuously, the production efficiency is low, and the labor intensity of the operators is increased. The research and development structure is simple and compact, easy to manufacture, and can be used for continuous operation on the production line. , Dehydration devices with high production efficiency are necessary for enterprises

Abstract

The invention provides a cooling and dehydrating device for reducing internal stress of plastic particles and a production technology, and relates to the technical field of plastic processing. The cooling and dehydrating device comprises a cooling water tank, a dehydrating tank and a heat air blowing case. The dehydrating tank which is obliquely arranged is fixedly connected with the cooling watertank, a movable water barrier is arranged at a joint end of the dehydrating tank and the cooling water tank, the heat air blowing case is arranged on the upper portion of the dehydrating tank, and aplurality of rolling shafts are arranged inside the dehydrating tank. The production technology for reducing stress difference of plastic mainly includes steps of partitioned melting, sinking and cooling, dehydrating and air drying, dicing and the like. The cooling and dehydrating device and the production technology have the advantages that the cooling and dehydrating device is simple in structure and easy to operate, and the human cost can be reduced by the cooling and dehydrating device; the production technology can be used for preparing the plastic, accordingly, the internal stress difference of the plastic can be effectively reduced by the aid of the production technology, the stability of plastic products can be enhanced by the aid of the production technology, and the like.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a cooling and dehydrating device and a production process for reducing the internal stress of plastic particles. Background technique [0002] Plastic internal stress refers to an internal stress caused by factors such as the orientation of macromolecular chains and cooling shrinkage during plastic melting processing. The essence of internal stress is the imbalance formed by macromolecular chains during melting processing. Conformation, this unbalanced conformation cannot immediately return to the equilibrium conformation suitable for environmental conditions when it is cooled and solidified. The form is stored in plastic products. Under suitable conditions, this forced unstable conformation will transform into a free stable conformation, and the potential energy will be converted into kinetic energy and released. When the force between the macromolecular chains and t...
