Quick drying device for spraying

Abstract

The invention discloses a quick drying device for spraying. The quick drying device comprises an elongated tunnel, a heat exchanger, a blower and a heating device. A guide rail is fixed on the top wall of the tunnel, a product conveying frame capable of sliding along the guide rail is arranged on the guide rail, a plurality of hot air inlets are formed in the lower end of the side wall of the tunnel, a plurality of cold air outlets are formed in the upper end of the side wall of the tunnel, a heating medium outlet of the heating device is connected with a heating inlet of the heat exchanger through a pipeline, a heating outlet of the heat exchanger is connected with a heating medium return port of the heating device through a pipeline, the blower is connected with an air inlet of the heat exchanger, a hot air outlet of the heat exchanger is respectively connected with the hot air inlets in the side wall of the tunnel through pipelines, and the cold air outlets in the side wall of the tunnel are connected with an air inlet of the blower through a pipeline. Drying temperature is uniform, products are not easily cracked, the tunnel is long and large in volume and contains more products, and the quick drying device is low in cost, high in efficiency, low in energy consumption and high in productivity.

Description

technical field [0001] The invention belongs to the field of door and window processing, and relates to a quick-drying device for spraying doors and windows. Background technique [0002] Wooden doors and windows, wooden furniture or wooden parts of doors and windows have high requirements for anti-mildew, insect-proof and anti-corrosion properties. This leads to higher requirements for the spraying of paint during the processing of the wood used. After the paint is sprayed on these woods, the paint film needs to be dried evenly and thoroughly. The paint film takes a long time to dry and can only form surface dryness in a short time. The production speed is slow, such as drying in the sun, the labor cost is high, and a large drying yard is required. At the same time, an environment with sufficient conditions is required. The drying time is long and manual handling is required. If drying is used, the heating system and heat transfer system are not sealed, the energy consump...
