Panel drying device for wood industry

Abstract

The invention belongs to the technical field of wood industry processing, in particular to a panel drying device for wood industry. The panel drying device for wood industry comprises an outer room body, an inner room body and a hot air circulating system, wherein a hot air flowing space is formed between the inner room body and the outer room body; the hot air circulating system comprises a stainless steel heating tube with a fin, a fan and an air duct; the stainless steel heating tube is arranged on the inner side of the outer room body; the stainless steel heating tube with the fin is composed of a high resistance electric heating alloy wire, a connecting screw, an electric heating tube and a heat-dissipating fin; the high resistance electric heating alloy wire is arranged on the uppersurface of the connecting screw; the connecting screw is connected to the electric heating tube; the electric heating tube is arranged in the heat-dissipating fin; and an air guide tube unit for guiding hot air into the inner room body to dry panels is arranged on the inner room body. By generating and introducing hot air to the hot air flowing space by means of the hot air circulating system to dry the panels placed in the inner room body all around, the panel drying device for wood industry is good in drying effect and high in work efficiency. The electric heating efficiency is high by adopting the stainless steel heating tube with the fin.

Description

Technical field [0001] The invention belongs to the technical field of wood industry processing, and particularly relates to a board drying device for wood industry. Background technique [0002] In the wood processing process, the drying treatment of the board has become an important step in the processing of the board. The existing board drying treatment device usually uses a thermal pressure plate for drying to make it fully contact with the board and ensure that the board is dried. The heat is evenly heated during the process, but the heating plate is used for drying, and the plates need to be put in batches, which reduces the efficiency of plate drying. After the drying, the temperature needs to be quickly cooled to realize the removal of the plates and the placement of the next batch of plates. It is not only serious heat loss, but also not suitable for continuous production and processing of large quantities of plates. During the drying process of a conventional drying ov...

[0002] In the process of wood processing, the drying treatment of boards has become an important step in the processing of boards. The existing board drying treatment device usually uses a heat pressing plate for drying, so that it can fully contact with the boards, which can ensure that the boards are dry during drying. The heat is even during the process, but the heat pressing plate is used for drying, and the plates need to be placed in batches, which reduces the efficiency of the plate drying, and after the drying is completed, the temperature needs to be cooled quickly to realize the removal of the plates and the release of the next batch of plates. Not only the heat loss is serious, but also it is not suitable for the continuous production and processing of large batches of plates

During the drying process of the conventional drying furnace, the heat in the furnace is directly discharged with the flue gas, and the waste heat of the flue gas cannot be effectively used. After the plate is dried, it carries a large amount of heat output, and the waste heat of the plate cannot be recycled and saved. Reduce energy consumption and reduce plate drying costs
