Wood electrothermal high-temperature processing device and heat treating device with combination drying function

Abstract

The invention relates to a wood electric heating high temperature processing device and a wood heat processing device which has the function of double-heat sources combined drying. The invention comprises a seal tank provided with a seal door, more particularly, the invention also comprises an electric heating sub-device, an air circulating sub-device and a heat exchanging sub-device. The heat sent out by the electric heating sub-device is uniformly distributed in the seal tank by the air circulating sub-device, thereby carrying out processing on the wood in the seal tank; the heat exchangingsub-device can be used for carrying out heating or temperature reducing on the wood. As the electricity is easy to be operated and controlled and the temperature control in the seal tank is accurate and reliable, the device of the invention has the advantages that the operation is simple and the using cost is low. The heat sent out by the electric heating sub-device is directly used for heating the wood by the air circulating sub-device in the seal tank, which has less heat loss and greatly improves the efficiency of the device greatly; furthermore, the device has less supporting facilities and is faster and simpler to be dismounted and mounted; the wood heat processing device which has the function of double-heat sources combined drying can carry out fast combined drying with high quality on the wood.

Description

technical field [0001] The invention relates to equipment for processing wood materials, in particular to equipment for high-temperature heat treatment of ordinary wood materials to improve their quality by changing their physical properties, and wood high-temperature heat treatment equipment with dual heat source combined drying functions. Background technique [0002] At present, the world's ecological environment has been severely damaged, and high-quality wood is becoming less and less. It is an important development direction of new wood materials in recent years to modify ordinary wood, especially artificial fast-growing wood, by chemical or physical methods, so as to greatly improve its color, stability, density, corrosion resistance and insect resistance. [0003] Most of the chemical modification of wood in the prior art adopts dyeing of wood to change its color sense, color difference, etc., and injects preservatives, insect repellents and resins to improve the cor...

AI Technical Summary

Problems solved by technology

[0006] 1. For the above-mentioned second high-temperature heat treatment equipment, the superheated steam heat injection device generally realizes temperature control by controlling the opening and closing of the valve, and it is not easy to realize a continuous and arbitrary temperature rise curve, so that it can be used for products with different moisture contents and different densities. When wood species and wood are mixed and placed together to receive high-temperature heat treatment, temperature control cannot be achieved in a targeted manner;

[0007] 2. The above-mentioned first and second high-temperature heat treatment equipment heat the water or oil in the boiler through fuel combustion, and then transfer heat through the heat exchanger to achieve high-temperature heat treatment of wood, so the heat loss is large, and the thermal efficiency of the equipment Low cost, high cost of use, and because the equipment requires many supporting devices, so the investment is high, the construction workload during installation is large, and it is inconvenient to disassemble and move; subject to certain restrictions;

[0008] 3. The heat treatment cycle of the above-mentioned first and second high-temperature heat treatment equipment is long, and generally takes 24 to 72 hours; the wood treated by the above-mentioned third high-temperature heat treatment equipment is not conducive to processing techniques such as painting and gluing, and the use cost is high;

[0009] 4. The above three kinds of wood high temperature heat treatment equipment all need to be equipped with boilers that use waste wood, fuel oil or coal as fuel. Disposal of dust removal equipment
