Oil mist recovery machine with purification mechanism

The utility model relates to an oil mist recovery machine, in particular to an oil mist recovery machine with a purification mechanism.

In the semi-finished product processing process using the machine tool for material removal, in the contact area between the workpiece and the tool, in order to reduce the friction and temperature of the area, a large amount of oil emulsion and lubricating emulsion are usually used. Cooling emulsions, etc., where most of the emulsion mixture will atomize in the surrounding space due to tool rotation during processing or evaporation due to temperature rise, usually these atomized substances will pass through the protection The obstructions are separated, but before the mixture of the atomized substance and the air is discharged to the external working environment, in order to prevent the pollution of the atmosphere and thereby ensure the health of the operator, a purifying device must be installed to filter the mixture.

Conventional purification devices typically use a series of filters to separate the air mixture from the oil portion or contaminants contained therein, such as a conventional oil mist filter device that draws the air mixture through a centrifugal impeller and The air mixture passes through a pipe member having a screw rod, and the vortex generated by the rotation of the screw rod causes micro-oil particles in the mixture to deposit on the inner wall of the pipe member, and then the micro-oil particles are collected by gravity at the bottom. Inside the container, then the remaining air mixture passes through a filter-type filter The filter is filtered and finally filtered and discharged through the centrifugal impeller.

However, the conventional oil mist filter device or other similar purification device often has the disadvantage of occupying a space due to its large volume, and is only suitable for the case of processing a large amount of air mixture. Therefore, the movement and position of the device are selected. A certain difficulty, in addition, another disadvantage is that inspection and maintenance are not easy, because the above-mentioned conventional device needs to remove the pipe for conveying the air mixture, or move a certain unit inside the device before the inspection and repair can be carried out. Work, and the unit may be installed in an inaccessible location, which takes a long time and a high cost. Furthermore, due to the purification of the air mixture, it is necessary to eliminate both fine-sized solid and liquid contaminants, however, Conventional purification devices often use low grade filters or inefficient parts, resulting in poor filtration efficiency.

Therefore, the object of the present invention is to provide an oil mist recovery machine with a purification mechanism with high purification efficiency and convenient maintenance.

Therefore, the novel oil mist recovery machine with a purification mechanism comprises a casing unit, a suction unit and a filtering unit.
