Embodiment Construction

[0049] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a schematic diagram showing the structure of the machine tool coolant purification device in the embodiment of the present invention. Such as figure 1 As shown, the coolant purification device for machine tools in this embodiment purifies the coolant in two stages.

[0050] First, the used coolant generated by the machine tool 1 is sent to the magnetic separation device 3 via the primary supply line 2 . In the magnetic separator 3 , grinding dust etc. which are magnetic bodies are mainly separated and recovered.

[0051] Next, the coolant from which the magnetic substance has been mainly removed in the magnetic separation device 3 is sent to a non-magnetic substance separation and filtration device (for example, a cyclone type removal device) 10 via a secondary supply line 4 . The non-magnetic material separation and filtration device 10 remove...

Abstract

The invention provides a coolant cleaning device for a machine tool, having only a cleaning tank for containing cleaned coolant to reduce the installation space of the device and to eliminate the need of cleaning of the inside of the tank. The coolant cleaning device has a magnetic separation device for removing mainly magnetic substances from a used coolant, a nonmagnetic substance separation and filtration device for removing mainly nonmagnetic substances from the coolant with magnetic substances removed, a clean tank for containing the clean coolant with nonmagnetic substances removed, and a pump for drawing coolant and supplying it to the nonmagnetic substance separation and filtration device. In the clean tank is provided a hopper for receiving the coolant with magnetic substances removed by the magnetism separation device. The hopper has an inlet opening for receiving the clean coolant contained in the clean tank. The pump draws the coolant in the hopper together with the clean coolant, which is taken in from the inlet opening, and supplies them to the nonmagnetic substance separation and filtration device.

Description

technical field [0001] The present invention relates to a coolant purification device for reusing coolant used in machine tools. In particular, it relates to a multi-stage cooling liquid purification device that combines a magnetic adsorption type magnetic separation device and a cyclone type centrifugal removal device, and the cooling liquid purification device for machine tools is provided only for storing Purified coolant tank (clean tank), and does not need to clean the tank. Background technique [0002] A coolant purification device that reuses the coolant used in machine tools, and discharges chips along with the coolant when metal materials, especially magnetic materials represented by steel materials, are cut and ground , grinding debris (cutting powder), etc. are separated from the liquid and recycled. Chips, grinding dust, and the like have various shapes, and therefore, various magnetic separation (recovery) devices have been developed from the viewpoint of rec...
