Description

A water-saving device for guide grooves for pre-painting treatment

technical field

The utility model relates to a pre-painting treatment device, in particular to a guide groove water-saving device for the pre-painting treatment.

Background technique

The coating production line is a process that consumes a lot of water due to the existence of many chemical treatment processes and water washing processes. As a pre-painting treatment technology, the traditional method of initial pre-treatment is tank immersion, which is dipped tank by tank according to the process flow. With the improvement and development of the process, two-in-one, that is, oil removal and rust removal, and three-in-one technology, that is, oil removal, rust removal, and passivation, have emerged. At present, domestic and foreign home appliance industries mostly use spray pretreatment, which is characterized by high production efficiency, easy operation, easy to realize automatic or semi-automatic production, good degreasing effect, and dense and uniform phosphating film. But no matter how it develops, the pre-treatment process of surface treatment is necessary. The traditional pre-painting cleaning process is: pre-degreasing water washing → draining liquid → degreasing water washing → draining liquid → hot water washing A → draining liquid → hot water washing B. For example, the announcement number is CN103357560B (2014-12-10), which discloses a pre-painting simulation device with tank immersion and spraying functions. Each process is also independent of each other, and each has its own water washing tank, water replenishment, and overflow sewage pipeline. . Each washing tank is supplemented with fresh tap water separately and discharged through the overflow, which consumes a lot of water and has a low water utilization rate, which not only wastes water, energy and cleaning agents, but also greatly increases the amount of sewage treatment. On the other hand, the large-scale shortage of water resources in my country is intensifying, and the shortage of water resources has increasingly become an important factor restricting my country's economic and social development. As my country's environmental protection regulations and sewage discharge regulations are becoming more and more perfect, environmental protection issues have been highly valued, sewage discharge standards are increasing, and sewage treatment costs are also increasing. How to design and formulate a reasonable coating production process, under the premise of ensuring product quality, use water rationally, save water, and minimize water consumption and sewage discharge are not only related to the survival and development of enterprises, but also a major factor in the national economy and people's livelihood. question.
