Example Embodiment

[0012] Example 1: Refer to the attached Figure 1~3 . Vertical drying room, which includes a drying room, the drying room is sealed by polyurethane composite panels, with doors at four corners, the interior of the panels is galvanized, and the base is all sealed in a sealed space. The interior of the space is divided into a rapid volatilization zone and preheating Zone, heating zone, cooling zone, heating fan 9 and cooling fan 2 are provided on one side of the enclosed space, and heating fan 9 is located on the upper part of cooling fan 12, and the heating zone air outlet 11 is provided on the side close to the heating fan. One side is provided with an upper air port 6 in the preheating zone, and is respectively connected to the heating fan 9 and the cooling fan 12 through the connecting air duct 10 and the air duct 3, and the heater 8 and the air duct are provided on the opposite side of the heating fan 9 and heating The device 8 is located on the upper part of the air duct 1...

Example Embodiment

[0015] Example 2: On the basis of Example 1, the drying method of the vertical drying room. The paint drying process is divided into a rapid volatilization zone, a preheating zone, a heating zone, and a cooling zone. The spraying wet material enters the working environment in the first link The high-speed air flow at room temperature blows the wet paint surface containing a lot of solvents, which promotes the large and rapid volatilization of paint solvents, prevents the blistering phenomenon caused by rapid heating in the heating zone, the paint begins to solidify and the solvent expands, and ensures the drying quality; The circulating transport mechanism of the pallet sends the wet materials vertically into the preheating zone, and under a certain temperature of hot air, it gradually meets the appropriate physical conditions for paint curing and solvent volatilization; after preheating, it is in the neutral zone for the paint to make full use of heat Make a short stay; then en...

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...
