Plastic forming and processing workshop cooling water recycling system and treatment process thereof

Abstract

The invention discloses a plastic forming and processing workshop cooling water recycling system and a treatment process thereof and belongs to the technical field of cooling water recycling. The recycling system comprises a plastic forming and processing device, a circulating pond, a water supply subsystem, a water return subsystem and a purification subsystem, the purification subsystem comprises a cooling and purification pond, and a plurality of roundabout tanks in sequential communication are arranged in the cooling and purification tank; a cooling water internal recycling device is arranged in the plastic forming and processing device, a water inlet of the cooling water internal recycling device is externally connected with the water supply subsystem while a water outlet of the sameis externally connected with the water return subsystem, the water return subsystem is communicated with a water incoming end of the cooling and purification pond, and the cooling and purification pond discharges water to the circulating pond which serves as a water source of the water supply subsystem. The problem of cooling and purifying the plastic forming and processing workshop cooling waterin an energy-saving manner is solved.

Description

technical field [0001] The invention relates to the technical field of cooling water recycling, in particular to a cooling water recycling system in a plastic molding processing workshop and a treatment process thereof. Background technique [0002] Injection molding and extrusion molding are two important plastic molding processing methods. During plastic injection molding, in order to improve production efficiency and ensure product quality, cooling water is often passed into the mold for cooling and heat preservation; during plastic extrusion molding, a large amount of cooling water is also required to cool and shape the molded product. The materials used in injection molding and extrusion molding are generally granular or powdery plastics. In order to prevent the molding materials from agglomerating and bridging, cooling water is often introduced near the feeding port of the injection molding machine or extruder to cool down to ensure granular or powdery plastics.
