Problems solved by technology

There is no other treatment before precipitation, the water impurities cannot be completely removed, and the suspended solids in the water cannot be removed well. In addition, the water hardening treatment has not been carried out. The hardness of the cooling water is too high during work, and scaling causes blockage of the pores of the EPS foam plastic mold. , affecting product quality and efficiency, and the water cooling device has a complex structure and high installation costs

Abstract

The invention discloses an EPS plastic foam cooling water circulating system, which comprises a cooling device, a first settling pond, a second settling pond and a reservoir, wherein a water outlet is formed in the cooling device; the water outlet is connected with a cooling water receiving system through a pipeline; the cooling water receiving system, the first settling pond, the second settling pond and the reservoir are sequentially connected with one another through a pipeline; a filter net or a filter is arranged between the first settling pond and the second settling pond; water softening equipment is arranged between the second settling pond and the reservoir; air cooling equipment is arranged between the water softening equipment and the reservoir; and the reservoir is connected with the cooling device through the pipeline. The overall pipeline cycle control is achieved; losses and waste of cooling water in the circulating process are reduced; a manual operation is reduced; the cooled water is clarified; pipe blockage is avoided; water hardness is softened; workshop production equipment and an EPS plastic foam mold are protected; the service lifetime is prolonged; the maintenance cost is reduced; and the yield of EPS foam is improved.

Description

technical field [0001] The invention relates to the field of foam cooling equipment, in particular to an EPS foam cooling water circulation system and a method for cooling EPS foam by the system. Background technique [0002] Polystyrene foam (Expanded Polystyrene referred to as EPS) is a light polymer. It uses polystyrene resin to add foaming agent, while heating to soften, generate gas, and form a foam plastic with a rigid closed-cell structure. Its processing method can be divided into pattern method and extrusion method according to the different foaming methods. This uniform and closed cavity structure makes EPS have the characteristics of low water absorption, good heat preservation, light weight and high mechanical strength. In the prior art, after the EPS foam is heated and formed, it needs to be cooled, and water cooling is generally used. After the water is cooled, it enters other processing steps, and the cooled water is usually drained directly. [0003] Chine...
