[0006]

Since the present invention is configured as described above, it has the following effects. Since it is attached to the automobile, it can be freely moved to the place of use and the water, sludge, etc. mixed in the kerosene tank or light oil tank can be quickly filtered. The operation is only required to insert the nozzle 12 into the bottom of the tank storing oil and light oil and drive the vacuum pump 7, so that the handling is extremely easy and the work can be continuously performed in a short time. . At this time, since the liquid enters the vacuum tank 5 through the first, second and third strainers, the inside of the vacuum tank is always clean. In this case, since the vacuum pump 7 has no liquid flow, there is no functional damage due to dirty liquid. Furthermore, the first, second and third strainers 2, 3, 4
The first strainer for filtering relatively coarse particles, the second strainer for filtering fine particles, the third strainer for filtering powder sludge, and the third strainer for filtering liquid impurities, so that strainer is not clogged and filtration efficiency is improved. The sludge can be discharged separately as coarse sludge, fine sludge, and powder sludge, so when sludge oil tank is filtered, sludge and water and mud can be treated separately. It's good. Moreover, since each of these operations can be performed by remote control by radio, it is a useful invention that enables efficient work with extremely labor-saving, without having to go to the vehicle one by one.
