[Prior art]

 As a method of cleaning the coolant. Conventional magnetic separators are generally used, but non-magnetic grinders, shaving machines, and other abrasive particles, as well as fine sludge, which has a weak suction force even with magnetic materials, cannot be captured or collected. Is difficult. Therefore, treatment with a filter device, a cyclone device, a centrifugal separator, or the like is required, but this increases the cost. Therefore, as shown in an example in Fig. 4, a magnetic separator 22 is attached to the precipitation separation tank 21. As an added simple device, the deposited sludge was manually scraped each time.

[0003]

[Problems to be solved by the device]

 Grinding machines, shaving machines, and other general machine tools have been improved in workability, and a large amount of chips and other sludge have been discharged. Most of them are collected and discharged by conventional magnetic separators or chip conveyors, but the fine sludge in them is not captured and circulates as it is mixed in the coolant, and the processing accuracy and surface roughness of the mother machine are improved. And causes troubles such as scratches. Further, this fine sludge gradually accumulates on the bottom of the tank, and progresses to a state where manpower is required to discharge it. Therefore, if the fine sludge is always separated and discharged, a magnetic separator having a stronger suction force is required because the magnetic sludge in the fine sludge is also fine, and a filter device or a cyclone device for the abrasive grains is required. Or, a centrifuge or the like is required, and it is becoming more and more difficult to install them for each machine because of the high cost and the expansion of space.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems. For the coolant used in the grinding machine or the coolant used in other general machine tools that gradually becomes polluted due to the accumulation of fine sludge. The machine is appropriately brought into contact with the machine, a powerful magnetic separator that can collect even the fine sludge is placed, and a filter is attached to the suction side of the coolant suction pump to extend the life of the pump and the powerful magnetic separator. This is a portable coolant cleaning device configured to clean the inside of the tank.

[0005]

[Action]

 A suction pump is placed on the carrier of the portable coolant cleaning device of the present invention, and the hose on the suction side extends to the coolant tank (hereinafter referred to as the main tank). A filter is attached to protect the separator.
