Description

Oil mist collector {Oilmist collector}

The present invention relates to an oil mist precipitator. More specifically, the machine tool such as a lathe, a grinding machine, and a milling machine sucks foreign matter such as oil mist and smoke generated by cutting oil when machining a metal material together with air to condense and collect the oil mist, And to discharge only the air that has been supplied to the oil mist accumulator.

Generally, when machining a metal material by using a machine tool such as a lathe or a milling machine, cutting oil is supplied to a portion cut by a cutting tool or the like. The cutting oil reduces the frictional resistance, decreases the cutting point temperature, Thereby extending the service life of the tool and improving the accuracy of machining.

However, when cutting a metal material rotating at high speed in a machine tool by a cutting tool such as a cutting tool, the cutting oil supplied to the cutting part is scattered in a state of fine particles such as mist due to the high rotational force of the metal material. The oil mist in the mist state scattered in such a manner as described above is extremely harmful to the human body because dust and metal powder are contained therein. Therefore, a device for suppressing the generation of oil mist when cutting a metal material using a machine tool A dust collector for sucking and treating the oil mist is proposed in Japanese Patent No. 10-0564297,

In the above-mentioned prior art, when one impeller is rotated by using the power of the motor to suck air, the oil mist sucked together with the sucked air is filtered by a plurality of filters, Since a plurality of filters need to be frequently replaced, a maintenance cost is required, and the operation of replacing the filter is troublesome and troublesome. In addition, the above-mentioned prior patent discloses a problem that the above- The oil mist tends to be collectively collected in the filler, so that the above-mentioned filter must be frequently replaced.

SUMMARY OF THE INVENTION The present invention has been proposed in order to overcome the above-described problems in the prior art, and a filter for collecting oil mist is made of a stainless steel demister filter, In the present invention, the inside of the dust collector is divided into a first collecting chamber in the lower part, a second collecting chamber in the middle, and a third collecting chamber in the upper part, and the outside air is sucked into the second collecting room while being rotated by the rotation power of the motor And a second suction fan for sucking the air sucked by the main suction fan is provided in the first suction chamber, wherein the auxiliary suction fan is rotatably mounted on the main suction fan, The oil mist sucked together with the air is introduced into the primary and secondary demister filters installed in the first and second collecting chambers, The third trapping chamber is provided with an air filter for filtering the gas, odor and the like contained in the air, and means for mounting a tertiary demister filter to the machine tool The present invention was invented in order to purify the indoor air of the workplace where the metal material is processed.
