A fully automatic drying oven

Abstract

The invention discloses a fully automatic drying furnace. The fully automatic drying furnace comprises a furnace body with a heating chamber, a fresh air replenishment system connected with the heating chamber, and a moisture discharge device with one end connected with the heating chamber and the other end connected with the fresh air replenishment system. The pressure difference generated by the system, the fresh air supplement system and the moisture discharge system in the heating chamber creates a negative pressure in the furnace body. Furnace openings are opened at both ends of the furnace body, and the air entering the heating chamber from the furnace mouth is opposed to the airflow generated in the heating chamber. . The fully automatic drying furnace moisture discharge system disclosed in the present invention is connected with the fresh air replenishment system, and the hot moisture is discharged after exchanging heat with the fresh air, which improves the reuse of heat energy and reduces energy loss; The relative size of the discharge volume and the fresh air replenishment volume creates a negative pressure in the furnace body, which counteracts the airflow entering the heating chamber from the furnace mouth, prevents the rising airflow of the circulating air, and significantly reduces the occurrence of the chimney effect.

Description

technical field [0001] The invention relates to the technical field of carbon fiber drying equipment, in particular to a fully automatic drying furnace. Background technique [0002] The drying furnace is a device used for drying operations. By heating the material, the moisture contained in it is vaporized and escaped to obtain a solid material with a specified moisture content. [0003] Carbon fiber is a new type of material, which has the advantages of low density, high strength, high modulus, corrosion resistance and high temperature resistance, and has been widely used in aerospace, ships and automobiles and other fields. The surface treatment of carbon fiber is an important link in the production process of carbon fiber. Drying treatment is an indispensable key step after carbon fiber surface treatment and water washing. The drying furnace is an important equipment for drying. [0004] In the related technology, there are obvious structural and system defects in the c...

Problems solved by technology

[0004] In the related technology, there are obvious structural and system defects in the carbon fiber drying furnace. First, the moisture generated after heating the material in the furnace body is directly discharged to the outside, resulting in a waste of energy; The outlet is directly discharged, resulting in a significant chimney effect, resulting in a large temperature difference between the upper and lower sides of the furnace, and the drying effect is not good
