Description

Technical Field [0001] The present invention relates to a high-performance cutting oil sludge separating device,

The present invention relates to a new concept of separating sludge contained in cutting oil more smoothly by interrupting the supply resistance of the cutting oil supplied to the cyclone separator.

Generally, when machining a workpiece using a machine tool such as a CNC machine or a machining center, a cutting machine, a pre-cutting machine, or other automatic cutting machine, high temperature is generated due to high speed machining, thereby shortening the service life of the cutting tool. And the coolant is also supplied to prevent scattering of chips generated during the machining process.

When such a cutting oil is supplied for the first time, there is no problem, but when used for a long time, the cutting powder contained in the cutting oil is precipitated to the bottom by its own weight and only the remaining cutting oil is reused as a circulating type. There is a problem that circulation occurs in a state in which the cutting fluid is contained due to the flow, thereby blocking the injection nozzle.

In addition, as described above, since the cutting powder contained in the cutting oil moves together with the cutting oil, it is excessively generated in the equipment, so that the loss of the power is excessively increased and the overheating of the cutting tool and the cutting tool occurs due to the defective supply of the cutting oil The cutting efficiency is extremely poor. On the other hand, there occurs a phenomenon that the cutting tool is broken or is seriously worn out, resulting in a time loss due to the replacement of the cutting tool, A problem of lowering occurred.

As a prior art for solving these problems, "Patent Registration No. 1673480, name / coolant regeneration and recycling system" is disclosed.

The prior art provides the effect of separating the cutting oil and the sludge while the cutting oil flowing through the cutting oil supply line is rotated along the inner circumferential surface by using the cyclone separator having the inner circumferential surface narrowed toward the lower end.

In the prior art, the coolant flowing into the cyclone separator is returned to the coolant inlet port by a strong flow rate in the process of pivotal motion, thereby pushing out the coolant flowing continuously, while supplying the coolant smoothly This causes a problem that causes performance degradation.

In addition, the cyclone separator is merely a principle function of separating the particles by the centrifugal force acting on the sludge by causing swirling motion, so that the performance of the cyclone is inevitably small.

In addition, a device for collecting the sludge separated from the cyclone separator and automatically discharging the sludge to the outside is not properly provided, so that it takes a separate time and manpower to collect the sludge.

In order to solve the above-mentioned problem, the present invention provides a method for preventing the supply resistance of the cutting oil by preventing returning to the coolant inlet port by the cutout oil return blocking wall during the process of turning the coolant flowing into the cone head of the cyclone separator. Technology.

Further, the present invention provides a technique for allowing sludge contained in cutting oil to be adsorbed to a sludge cone by static electricity generated by charging (-) / (+) electricity connected to a cutting oil and a sludge cone.

The present invention also provides a technique for collecting sludge separated and discharged from a cyclone separator into a sludge collection tank and then automatically discharging the sludge discharge conveyor to the outside.

According to the present invention, since the cutting oil is guided smoothly into the collecting space inside the cyclone separator, the cutting oil is prevented from returning to the coolant inflow port by the cutoff oil return blocking wall, thereby preventing the supply resistance of the coolant, Of course, it provides the effect of drastically improving the performance of separating sludge through smooth supply of cutting oil.

Further, according to the present invention, due to the electrostatic principle generated inside the sludge cone, the sludge contained in the cutting oil is adsorbed on the sludge cone, so that the sludge separation performance is greatly improved and a large amount of water treatment can be performed, It is possible to reduce the cost of the system.

In addition, the present invention reduces the time and manpower required for collection of sludge by automatically discharging the sludge separated and discharged from the cyclone separator to the sludge collection tank and discharging the sludge discharge conveyor to the outside, And provides an easy effect.
