Vertical drying shed and drying method

Abstract

The invention relates to a vertical drying shed and a drying method. The wall body of the drying shed is spliced into a relatively closed space with doors at the four corners by polyurethane composite boards. The inside of the space is divided into a rapid volatilization area, a preheating area, a heating area and a cooling area. A heating fan and a cooling fan are arranged at one side of the wall body; the heating fan is located at the upper part of the cooling fan; a heating area air outlet is arranged at one side of the heating fan and a preheating area upper air port is arranged at the other side; the wall body opposite to the heating fan is provided with a heater and an air channel; a fan is arranged at one side of the heater; a volatilization fan is arranged at the lower part of the fan and is communicated with an air channel port; and a lower air port of the cooling area is connected with an air outlet of the heating area. The invention has the advantages that firstly, the closed drying space is convenient for batch drying, improves the heat utilization ratio and is convenient to collectively process air dust and volatilized paint solvent; secondly, ideal combination of a heat field and an air field and the adjustment of the airflow are realized; and thirdly, the paint quality of spraying workpieces is ensured, and the effective rate of energy is improved.

Description

technical field [0001] The invention relates to a vertical drying room and drying method with high heat utilization rate, fast drying speed, stable quality, safety and reliability. Dry processing occasions. Background technique [0002] CN2463751, name "hot air dryer", this utility model includes a furnace, air inlet and outlet, and smoke outlet, the dryer has multiple layers of annular air ducts with different diameters, the lower part of the inner wall of the outer air duct and the lower end of the second air duct The inner wall of the second layer of air duct is the inner wall of the furnace, the upper end of the second layer of air duct communicates with the bottom end of the third air duct through a metal tube, and the upper end of the third annular air duct passes through the metal tube and the innermost layer. The upper ends of the air ducts of the inner layer communicate with each other, and the bottom of the inner layer air duct communicates with the air outlet pip...

AI Technical Summary

Problems solved by technology

Its disadvantages: first, mass production cannot be realized; second, low heat utilization rate, slow drying speed, and poor effect; third, poor safety

[0003] In the woodworking and furniture industry, the requirements for paint drying time, quality, and environmental protection are constantly increasing. The quality of the coating cannot be guaranteed under the conditions of manual spraying and natural drying of the paint. During the drying process, the handling of materials, placement space, and the degree of cleanliness of the air, The drying time, batch size, and the connection between the upper and lower processes are not compatible with the entire production line; although there are already horizontal upwind dryers and other drying equipment, they still occupy too much space, the production line is too long, and the drying time is not easy to match with the beat of the production line, etc. question
