Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil mist collector (oil mist) having a function of separating and collecting oil mist (oil fume) generated during grinding or cutting by an NC lathe or a multi-axis automatic lathe. The present invention relates to a collision collecting filter suitable for use in an oil mist collector, which is used in the technical field of (collector).

[0002]

2. Description of the Related Art An oil mist generated when performing metal grinding or metal cutting in a machine factory or when performing a cleaning operation using oil is disclosed in, for example, Japanese Patent Laid-Open No. 55-18256.
Or the oil mist collector found in Japanese Utility Model Publication No. 4-87721, or in Japanese Utility Model Publication No. 1-181.
Collection using an electric dust collector as seen in Japanese Patent Publication No. 95,
Have been removed.

However, in the latter electrostatic precipitator, the cleaning of the electrodes is very troublesome and there is a problem in terms of maintenance, the structure is complicated and the price is high, and the electrode is used in addition to water-soluble cutting oil. There was a problem we could not address.

[0004]

Therefore, in the case of separating and collecting oil mist such as water-soluble cutting oil, the oil mist collectors shown in the above-mentioned publications are used. An eliminator (collision collection filter), a demister, and a filter are provided side by side on the passage of the sucked airflow. By passing these airflows in the order of the eliminator, demister, and filter, the oil mist is removed from the airflow. To separate and collect
The collected oil mist adheres to the surface of each collision plate of the eliminator and hardens, or adheres to the inside of the metal mesh of the demister and hardens, which deteriorates air permeability. It is necessary to remove the eliminator and the demister from the inside of the machine body and clean them with an ultrasonic cleaning machine using a solvent, which is very troublesome for maintenance.

Therefore, the technical problem of the present invention is that the oil mist can be effectively separated and collected from the sucked airflow, and the maintenance of maintaining the oil mist collection capability without cleaning is very important. It is to provide a simple collision collection filter for an oil mist collector.

[0006]

Oil mist is adsorbed on the high-performance oil adsorbent in contact, separated and collected, and only clean air from which oil mist has been removed can be passed between the collision plates.
Also, the oil mist adsorbed on the high-performance oil adsorbent of each collision plate gradually grows and enlarges as it flows down to the bottom due to the weight and becomes an oil droplet, which naturally accumulates inside the bucket etc. through the drain pipe etc. Because you can
This makes maintenance such as filter cleaning unnecessary.

According to the means described in (2) above, due to the combination of a large number of collision plates formed in a substantially channel-shaped cross section, the respective passages are discontinuous on the passage of the suction airflow, and even if each passage is Since it is possible to provide a collision collection filter that is configured to bend intricately and suddenly change the passage speed of the airflow to generate turbulence, the oil mist contained in the airflow can be collided with each other. The high-performance oil adsorbent adhering to the front and back of the plate can be surely adsorbed, and an excellent collection effect can be exhibited.

According to the means described in (3) above, the combination of a large number of collision plates having a channel structure with a substantially U-shaped cross section makes the shape of the suction passage more complicated and changes the passing velocity and turbulence. Since the rate of occurrence can be further increased, it is possible to further enhance the effect of adsorbing oil mist by the high-performance oil adsorbent, and by combining the collision plates formed in the same shape, the manufacturing cost of the collision collection filter. Makes it possible to cheapen.

According to the means described in the above (4), the combination of a large number of collision plates formed in the shape of a polygonal channel having a bent portion in the middle makes the shape of the suction passage more complicated and makes the oil mist. It is possible to further increase the collection rate of.

As described above, the technical problems described above can be solved by the above means, and the problems of the conventional art can be solved.
