Description

  The present invention relates to a mobile multi-function cleaner used for removing sludge or metal chips in a liquid storage tank.

  Conventionally, when cleaning metal chips contained in chemical precipitates and cutting oil during metal processing, a liquid storage tank, precipitate filtration, chip removal, and these recovery devices must be installed separately. It was. However, according to the gist of the patent document 1 filed earlier by the present applicant, a chip separation chamber and a specific gravity separation chamber are installed on the upper part of the apparatus body, and the precipitate in the liquid storage tank is sucked with a vacuum pump. Then, after separating the fine metal chips and the cutting oil contained in the precipitate, the refined cutting oil is reused, but when the precipitate and the metal chips are collected in a chip collection tank by a predetermined amount or more, There is a drawback that the operation of the cleaning machine must be temporarily stopped to remove the chip. In order to solve this problem, in Patent Document 2 filed earlier, the deposit and the metal chips are automatically collected in the chip collection tank by installing a transfer conveyor on one side of the filtration drum. It was to so.
