Description

The present invention relates to a chemical solution removing apparatus and a chemical solution coating apparatus that removes an extra chemical solution other than a chemical solution adhering to the wood after applying a chemical solution for preservatives and ants to wood having a large number of micropores formed therein.

  In order to prevent wood damage caused by termites, larvae, etc., and rotting by decaying fungi, an antiseptic and ant treatment is performed on wood. As an example of this antiseptic and ant processing, there is a method in which the eyes are cut in advance on the surface of the wood only at an appropriate interval, for example, with a blade, and the chemical solution is permeated into the wood from the eyes. The process of cutting fine holes such as is called insizing. For example, a chemical solution coating apparatus described in Patent Document 1 is known as a technique that uses this insizing process to achieve the penetration of a chemical solution for preserving and preventing ants into wood.

The chemical solution applicator is provided with a plurality of rotating brushes that rub the surface of the wood to which the chemical solution has been applied in the vertical and horizontal directions. The plurality of rotating brushes are attached to a rotating shaft that is rotated by a driving mechanism.
