供し、従来の欠点を解消することを目的とする。After a predetermined time according to the settings of the control system, the on-off valve 1 is opened and the impregnating liquid j is returned to the storage tank k by the air compressor f.
The product to be treated b is then taken out of the impregnating tank a to complete the impregnation process, but the impregnating liquid j remains in the storage tank k until the next impregnation starts. In addition to shutting down the exhaust system, control system, and piping system, it is often necessary to intervene to replenish the impregnating liquid that is consumed by repeated use of the impregnating process because it cannot be automatically refilled.
This has the disadvantage that idle time during the impregnation process accumulates, resulting in low productivity. The present invention has been made in view of these drawbacks, and in the first invention, two impregnation tanks are provided for accommodating the products to be treated, and each of the impregnation tanks has a sealed door at its upper end that can be opened and closed. At the same time, a communication pipe that communicates the bottoms of both impregnation tanks is connected via an on-off valve, and both impregnation tanks can be stored alternately, and a vacuum pump and an air compressor are installed at the top of both impregnation tanks. In the second invention, an auxiliary tank for automatically replenishing exhausted impregnating liquid is connected to a communication pipe connecting both impregnating tanks via an on-off valve. A third object of the present invention is to provide an impregnation method using two impregnating tanks in which the two impregnating tanks are operated alternately to shorten downtime, thereby solving the conventional drawbacks.
