Hybrid type oil mist collecting device {Hybrid type oil mist collecting device}

The present invention relates to a hybrid oil mist dust collecting device, and more particularly, to a hybrid oil mist dust collecting device in which a dust collecting method using a general filtration method and an electric dust collecting device using a discharge electrode and a dust collecting electrode are combined, and has a large dust collection area. will be.

In general, when machining metal materials using machine tools such as lathes or milling, cutting oil is supplied to the part to be cut by a bite. The above-described coolant reduces frictional resistance, lowers the temperature of the cutting point, and cools the bite. As a result, it has the advantage of extending the life of the tool and improving the machining accuracy.

However, when cutting a metal material rotating at high speed in a machine tool with a bite, etc., the cutting oil supplied to the part to be cut is scattered in all directions in the form of fine particles such as fog by the high-speed rotational force of the metal material. As such, the oil mist in the misty state that scatters in all directions is very harmful to the human body because it contains dust, metal powder, etc. Therefore, it is a device to suppress the occurrence of oil mist when cutting and processing metal materials using machine tools. As a result, a dust collecting device for suction treatment of oil mist has been proposed.

A typical dust collecting device includes a dust collecting body having an inlet through which foreign substances are introduced, and a dust collecting pump providing a dust collecting force to the dust collecting body. Here, one side of the dust collecting body includes an inlet through which foreign matter is introduced by being opened toward the machine tool or manufacturing facility, and a filter member provided on the other side facing the inlet to filter foreign matter. In addition, a connector is formed on the upper side thereof to provide a suction air flow to the inside of the dust collection body by being connected to the dust collection pump.

However, in the conventional dust collecting apparatus having the above configuration, the transmission of the dust collecting force of the dust collecting pump is not smooth at the inner edge of the dust collecting body. Therefore, the dust collection force of the dust collection pump is concentrated in the center of the dust collection body and is relatively low on the inner surface, and this deviation of the dust collection force remains only in the part or area where the dust collection power is high. There is a problem that the dust collection efficiency is lowered.

In order to compensate for this problem, the present applicant has developed a fusion dust collecting device that combines a general dust collecting device and an electric dust collecting device using a discharge electrode and a dust collecting electrode as disclosed in Korean Patent Publication No. 10-16012880.

The applicant of the present invention continuously researches and develops a fusion-type dust collector to develop a dust collector that can filter oil mist in multiple stages and secure a wider dust collection area.
