Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is, for example, wood processing used when coloring wood treated with a solvent vapor of a chlorinated organic solvent and water vapor accompanying it with a dye, or when processing such as incombustible processing with a chemical solution for incombustible processing. The present invention relates to a processing apparatus.
[0002]
[Prior art]
When coloring or non-combusting the wood, the wood is rapidly dried using methylene chloride as proposed in, for example, JP-A-6-137757 and JP-A-7-32315. The rapidly dried wood is subjected to a color processing treatment with a dye to a desired color or a non-flammable processing treatment with a chemical solution for non-combustion treatment.
In these coloring processing and non-combustible processing, after putting wood into a processing container fixed in the processing place and evacuating it, this processing container is filled with dyes or chemicals for non-combustible treatment, and wood is added to these chemicals. Immersion is performed to increase the pressure in the processing vessel and impregnate.
After that, after discharging the chemical solution from the processing container, the wood is taken out and dried.
[0003]
[Problems to be solved by the invention]
In the above-mentioned conventional wood processing, since the processing container is installed substantially horizontally in the processing plant, it takes a considerable time to discharge the chemical solution after finishing the processing of the wood from the processing container. For this reason, there is a problem that productivity is greatly reduced.
In order to deal with these problems, it is conceivable that the processing container is inclined in advance so that the discharge port side is lowered, but in this case, not only is it difficult to line up the timber, but part of the timber is exposed from the chemical solution. There is also a problem that unevenness occurs in the processing of wood.
Further, if a discharge gradient is provided on the bottom surface of the processing container, the amount of the chemical solution increases and it becomes uneconomical.
[0004]
In addition, since the processed wood is taken out of the processing container and dried, it takes time to take out the wood, and the wood to be taken out is moist with a chemical solution, and the risk of the chemical solution adhering to the worker There is also a problem that it is likely to cause a decrease in work environment.
Furthermore, when removing wood from a wood processing container, if the wood or chemicals are heated to a high temperature, you must wait while the temperature drops to a workable temperature. There was a problem that decreased.
Therefore, the present invention has been proposed in view of the above-described problems, and an object of the present invention is to provide a processing apparatus that is safe and has high processing efficiency without taking time and effort.
[0005]
