Air jet cooling device, continuous hot-in and cold-out hot press, and continuous cooling method thereof

Abstract

The invention discloses an air jet cooling device, a continuous hot-in and cold-out hot press, and a continuous cooling method thereof. The air jet cooling device comprises a plurality of cooling pressure plates, a gas supply pipeline and a water atomizer; the multiple cooling pressure plates are arranged so that upper and lower layer structures are formed, and the side faces of the cooling pressure plates are provided with a plurality of long holes uniformly; one end of each long hole is closed, and the acting surface of a working area of the cooling pressure plates is provided with a plurality of air jet holes uniformly; each long hole communicates with a plurality of air jet holes, and the gas supply pipeline comprises a plurality of gas supply branch pipes and a gas supply main pipe; the gas supply branch pipes communicate with the gas supply main pipe, and further communicate with the other end of each long hole in the side faces of the cooling pressure plates; and the side wallsof the gas supply branch pipes of the former 1 / 5-1 / 3 of the cooling pressure plates of the upper and lower layer structures communicate with the water atomizer. The air jet cooling device has the advantages of the simple structure, good cooling effect, high efficiency, energy conservation, less heat loss of a cold-out method, short production cycle, energy saving and high quality of manufactured products.

Description

technical field [0001] The invention relates to the field of wood-based panels, in particular to an air jet cooling device, a continuous hot-in and cold-out hot press and a continuous cooling method thereof. Background technique [0002] For the thermosetting molding of bamboo plywood and other unit blank structures that are glued by dipping, due to their high moisture content, it is not easy to dry by conventional methods. When thermosetting and gluing, the water is not easy to evaporate. When using the hot pressing method of hot in and hot out, bubbling and sticking are prone to occur, which greatly affects product quality and production efficiency. Therefore, traditional bamboo mat plywood is mostly manufactured by cold-hot-cold method, but this The production cycle is long, the efficiency is low, the heat loss is large, the consumption of water and electricity is large, and the cost is high. . Contents of the invention [0003] In view of the above disadvantages, the...
