Oil mist collector

The present invention relates to an oil mist collector, and more particularly to an oil mist collector that can guide the discharge of purified air by a multi-step separation process performed in mutually different ways to make it more efficient The oil and air contained in the oil mist generated in various industrial sites are separated and discharged.

The present invention relates to an oil mist collector, and more particularly to an oil mist collector that can guide the discharge of purified air by a multi-step separation process performed in mutually different ways to make it more efficient The oil and air contained in the oil mist generated in various industrial sites are separated and discharged.

A typical oil mist collector is roughly classified into a screening program filtration method, a centrifugal separation method, and an electrostatic separation type collector. The filter of the screening program is the most common form of collector structure. A fan and a screening program are installed inside the body to suck in the oil mist, thereby filtering the impervious oil particles through a screening program. And only the purified air is discharged. However, in order to exhibit high filtration efficiency, it is necessary to frequently replace the filter element, and thus there is a problem of economical disadvantage in terms of maintenance cost.

The centrifugal separator uses a centrifugal separation device to form a swirling gas stream, thereby utilizing centrifugal force to separate oil and air. The shape and structure of the centrifugal separation device can be variously designed according to the nature of the separated object, and thus it is necessary to develop a most suitable and effective structure. On the other hand, compared with the above-described screening program filtration method, the centrifugal separation method can reduce the maintenance cost, but the filtration efficiency is also low, so that there is a problem that the fine particles are not separated.

Further, the collector of the electrostatic separation type is obtained by charging the oil mist to coagulate the oil particles and then separating them, and is usually used together with the above-described screening program filtration method or centrifugal separation method.

On the other hand, regarding the above-mentioned problem, the related content is disclosed in the Korean Laid-Open Utility Model Publication No. 20-0418713, and is a form of a collector including the centrifugal separation method and the screening program filtration method described above.

In this regard, the structure is briefly observed: in the internal structure of the body, a fan is disposed at the upper and lower portions of the body, and the oil mist is centrifugally separated at the lower portion, and after filtering at the upper portion by means of a screening program, Exhaust the purified air.

In this way, two different separation methods are mutually grafted to improve the filtration efficiency. However, due to the structural limitations of the internal structural elements, a smooth airflow is not formed between the lower portion and the upper portion, eventually resulting in the inevitable setting of more than one blower fan. problem.

Further, since the motor for driving the blower fan is directly exposed to the flow path of the airflow, there is a problem that the life of the device is shortened due to the adsorbed oil stain or the like, and thus it is urgently needed to develop more efficiently. Improved structure collector.

In other words, the present invention further provides a guide vane 53 having a curved shape, and the guide vane 53 guides the oil mist that has moved through the penetration portion 51 in accordance with the characteristics of the coil hovering guide unit 50 that rotates itself by the rotational force of the drive motor 70. A stronger spiral rotation, at which point the protruding length of the guide wings should not be too long or too short.

For example, in order to form the coil hovering guide unit 50, after preparing a circular plate, the edge faces are evenly cut in a fixed manner, thereby guiding the formation of the penetrating portion and the extending portion, and arranging the cut side faces. Thus, the generation of the guide wings disclosed in the present invention can also be guided.

The present invention formed according to the structure as described above has an effect that not only the discharge of the purified air can be guided more efficiently by the multi-step separation process performed in mutually different manners, but also the first collision separation and the second are sequentially performed. The secondary centrifugal separation and the third centrifugal separation, and the different centrifugal separation methods are carried out in parallel, thereby further maximizing the filtration efficiency and oil recovery rate by the oil mist.

The present invention has been described with reference to the embodiments shown in the drawings, but this is merely an exemplary embodiment, and it will be apparent to those skilled in the art Example. Therefore, the true technical protection scope of the present invention is to be construed as the scope of the invention, and all the technical ideas contained in the same scope are to be construed as being included in the scope of the invention.
