Description

A kind of crushing system with refrigerating function

Technical field

This utility model relates to technical field of chemical, particularly relates to a kind of crushing system with refrigerating function.

Background technology

Usually a kind of crystalline plastics of PET, PET bottle due to light weight, do not allow the advantages such as frangible, energy consumption is low, instead of some traditional packaging material, widely apply in fields such as food, beverage, cosmetics. From the viewpoint of energy-conserving and environment-protective etc., people would generally be undertaken waste and old PET bottle sheet reclaiming and in addition again with. In recent years, the research about the recycling aspect of waste PET bottle sheet is very many, and wherein, the production that waste and old PET bottle sheet is applied to water-soluble polyester is a kind of mode that chemical industry is try to.

Owing to waste PET bottle sheet is originally as reworked material, wherein contain diversified impurity, the inferior quality of the water-soluble polyester product of production. And, mechanical impurity such as iron block, screw etc., the badly damaged flour mill of meeting in later stage crushing process, reduces the service life of flour mill.

Being modified further, since water-soluble polyester product adds multiple supplementary material in process of production, the vitrification point of product is reduced to 55 degrees centigrade relative to conventional polyester product; And water-soluble polyester is in the grinding and processing process in later stage, owing to mechanical activation comminution operation makes temperature of charge significantly promote, near or above vitrification point. If water-soluble polyester is made directly packing processes after pulverizing, then too high temperature can be lumpd reunion after packaging, and (macromolecular material is thermoplastic to bring inconvenience, Ye Shi company to sustain a loss to client, heat can be produced under the effect of mechanical force, if got rid of not in time, material adhesion will be made, parking of gently then stopping work, heavy then damage machinery equipment), especially in hot summer, temperature is up to more than 35 degrees Celsius, and this phenomenon highlights especially. In order to solve this problem, the space that the water-soluble polyester granule after pulverizing is positioned over temperature relatively low is generally cooled down by people, treats that its temperature carries out packing processes again close to room temperature.
