Dry-type filtering box for textile paint spraying

Abstract

The invention relates to a dry-type filtering box for textile paint spraying. The dry-type filtering box for textile paint spraying comprises a drying room body, a heat exchange structure and an exhaust blower; double open doors are arranged on the two sides of the drying room body correspondingly, and the bottom face of the interior of the drying room body is provided with a front rail, a rear rail and a plurality of uniformly-arranged air outlet plates, wherein the front rail and the rear rail are arranged in a corresponding mode; the rails are arranged in the extension direction of the drying room body, meanwhile air in-out openings are formed in the side wall of the drying room body, and a vertically-arranged air exhaust pipeline is arranged at the top of the drying room body and communicates with the drying room body; the heat exchange structure comprises a heat exchange room body, the heat exchange room body is placed on one side of the drying room body and arranged to be tightly close to the air in-out openings, and a heat exchanger and an air in-out pipeline connected with the heat exchanger are arranged in the heat exchange room body; the air in-out pipeline is vertically arranged, and the upper end of the air in-out pipeline is placed on the exterior of the heat exchange room body; and the exhaust blower is placed at the side edge of the exterior of the heat exchange room body. The dry-type filtering box for textile paint spraying has the advantages of being simple in structure, efficient, environmentally friendly and capable of reducing cost.

Description

Technical field: [0001] The invention relates to the field of textile painting, in particular to a dry filter box for textile painting. Background technique: [0002] Textiles often need to be painted on the surface. The paint atomized by high-pressure air during spray construction forms a large amount of paint mist. The paint mist is composed of paint particles and solvents. The specific gravity of paint mist is small. It floats in the air and settles on the surface of the workpiece. The quality of the workpiece, the operator’s inhalation of paint mist is harmful to health. Many textile manufacturers use water curtain spray booths to eliminate paint mist. The paint mist generated by the spray gun flows to the exhaust port of the water curtain to form a parallel flow of air flow, reducing the effect of paint mist on spraying. The interference of the workpiece improves the quality of the paint mist. The water cycle is used for repeated flushing, and the cost of adsorbing the paint...

Problems solved by technology

[0002] Textiles often need to be painted on the surface. The paint atomized by high-pressure air during spraying construction forms a large amount of paint mist. The paint mist is composed of paint particles and solvents. The paint mist has a small specific gravity, floats in the air, and settles on the surface of the workpiece. The quality of workpieces, the inhalation of paint mist by operators is harmful to their health. Many textile production enterprises use water curtain spray booths to remove paint mist. The interference of the workpiece improves the quality of the paint mist, and the water cycle is used for repeated showering. The cost of absorbing the paint mist is low, and the effective removal rate of the paint mist is 35%. The disadvantage of the water curtain spray booth: high humidity during operation, due to the use of water as the paint As an adsorbent for mist, in order to improve the adsorption performance, water must be circulated at a high speed, and the air containing paint mist must be sprayed and cleaned. A large amount of water sprayed and volatilized in the water curtain machine will increase the humidity of the spray booth, and the furniture will be painted. Many coatings in the installation are not suitable for construction in an environment with high humidity. High humidity will affect the quality and drying speed of the paint film; Disadvantage 2: Secondary sewage discharge, the discharged sewage will affect the environment
