Embodiment Construction

[0063] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0064] The following are three specific embodiments of the present invention.

[0065] Option One:

[0066] Such as figure 2 As shown, the fresh air is pressed into the heat exchanger (212a, 212a, 208c) inside the second volatilization section 230 by the air inlet (211a, 211d) of the solidification section 240 via the air intake fan (208a, 208c) controlled by the temperature sensor 213b and the temperature controller 214b. 212b), enter the solidification section 240 after heat exchange with the second volatilization section 230 , and become the source of fresh air for the solidification section 240 . The upper part of the curing section 240 is provided with an air curtain fan 209 a and a top sealing device 210 , preventing the gas in the curi...

Abstract

The invention discloses an energy-saving implementation method applied to preparing composite materials by means of vertical drying and curing. The method increases air pressure inside a curing section or reduces air pressure inside a first volatilizing section to change the circulation direction of hot air inside a drying oven body by arranging an air curtain fan, an axial flow fan and a heater in the drying oven body or introducing an external fan, the hot air inside the drying oven body flows from top to bottom, the utilization rate of the air and the volatilizing efficiency of solvents are increased by means of the principle of 'backwash', spillage of waste gas is reduced, solvent vapor pressure in the waste gas is increased, and the waste gas can be collected to be harmlessly treated. Besides, as the heat of the heated air inside the drying oven body is reasonably used, the temperature of the exhausted waste gas is greatly reduced, the energy consumption of equipment is greatly reduced, and the energy saving effect of the equipment is realized.

Description

Technical field: [0001] The invention relates to an energy-saving structure of a vertical traditional drying and curing oven, in particular to an energy-saving realization method of a vertical drying and curing method applied to the preparation of composite materials. Background technique: [0002] As we all know, many composite materials are manufactured by impregnating the base material (such as glass fiber, braided material, etc.) with a thermosetting resin (such as silicone resin, etc.) volatilized and solidified. [0003] Among them, the curing process of many thermosetting resins must first go through a low temperature (70-100 degrees Celsius) volatilization process, first volatilize the solvent, and then heat and cure in a high temperature (170-220 degrees Celsius) and clean solvent-free air. However, in an atmosphere saturated with volatile solvents in air, the curing process is prolonged or even impossible. [0004] Such as figure 1 As shown, it is a side cross-s...
