Description

Mist eliminator

More particularly, the present invention relates to a mist collecting apparatus for collecting fine particles of water or oil floating during exhaust, and more particularly, to a mist collecting apparatus which draws mist containing mist, The present invention relates to a mist collecting apparatus for collecting a mist while collecting a mist by an element mesh unit and for automatically cleaning an element mesh unit and a collecting body as needed.

In general, a large amount of processing oil (cooling oil, cutting oil, aqueous detergent, oil detergent, etc.) is used for cooling, lubrication and cleaning in machining processes such as cutting, turning, grinding and cleaning of metals. And fine particles that are volatilized and scattered along with fine chips in the turning or grinding process and suspended in the air are referred to as mist.

Since the above mist is very fine, it is not easy to confirm whether or not the occurrence of the mist is caused. Therefore, the worker performing the metal processing is unconsciously exposed to the mist and the disease caused by various cancers, non-malignant respiratory diseases, skin diseases and microorganisms, But also causes malfunction and short circuit of the machinery and affects the product.

The conventional mist collecting apparatus is largely divided into a collecting apparatus of a filter system and a collecting apparatus of a rotary filter system.

The filter type collecting device has a good initial mist removal efficiency, but it can not be removed if the mist is adhered to the filter. As a result, the pressure loss (excessive clogging of the filter due to filter clogging, There is a problem that the overall efficiency of the ventilation system is lowered and the oil adhered to the filter is corroded together with the filter to generate odors in the workplace.

In order to solve the above problem, expensive filters have to be frequently replaced, resulting in excessive maintenance costs, continuity of work, and loss of workforce.

The rotary filter type collecting device adopts the inner filtration method, so that it can not be removed when the metal chip or the foreign substance adheres to the inside of the filter. The blowing fan is installed inside the collecting device and the positive pressure is formed at the rear end of the collecting device There is a problem that the condensed oil leaks through the gap of the duct line and the collecting method depends on the rotational force of the blowing fan, so that the rotational force (RPM) is not sufficient and the mist can not be removed sufficiently This causes a direct failure of the exhaust system.

In order to solve the above-mentioned problem, according to a conventional art, a bottom surface is formed in a conical shape in Patent Registration No. 10-0506985 (2005.08.01), a mist inlet is provided in the tangential direction of the outer side and a mist outlet is provided in the other side A filter support of a multi-mesh network equipped with a filter is inserted and installed inside the filter housing in which the filter check window is installed, the rotary shaft of the filter support is connected to the lower motor of the filter housing, and the filter housing has a conical shape The present invention provides a centrifugal mist collecting apparatus for an outer filtration type centrifugal mist capable of purifying mist generated during metal working by centrifugal force by coupling a housing and controlling the motor by an inverter.

In addition, the mist removal system by the vacuum system is more important than the general blower or fan system maintenance, because it is directly related to the failure of the vacuum pump and maintenance.

Therefore, the mist trapping by the vacuum system was disassembled directly from the mist collecting device periodically (1 to 2 times per week), and the mist film was dissolved in the solvent for a long time or reused after cleaning using an ultrasonic cleaner or the like.
