Description
Technical Field
The utility model relates to an oil mist filter in clarification plant field.
Background
In the metal processing process, because the oily cutting fluid is used for mechanical processing, the oily cutting fluid can be atomized to generate oil mist under normal conditions, the oil mist mainly exists in a droplet form, the diameter range of the droplets is wide, and the test result of the particle size of the oil mist shows that the total diameter content in the air of a processing workshop is much larger than the oil mist test value due to the fact that 95% of droplets with the diameter smaller than 3um. are evaporated in a large quantity, medical research proves that the oil mist is inhaled into a lung and exhaled out and deposited in the lung, so that the harm to a human body is caused, the smaller the particles are, the more polycyclic aromatic hydrocarbon and heterocyclic compounds are contained, the greater the harm is, and even diseases such as lung cancer can; moreover, the machine tool is polluted by oil dust, the service life of the machine tool is shortened, and the production efficiency is also reduced. The traditional oil mist filter is an electrostatic purification device, the purification efficiency is low, the energy consumption is high, and the used electrostatic liquid is easy to generate secondary pollution.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, an object of the utility model is to provide an oil mist filter that simple structure, purification rate are high and can not produce secondary pollution.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides an oil mist filter, includes rose box, filter body and high efficiency fan, and filter body and high efficiency fan setting are in the rose box, and high efficiency fan installs on filter body its characterized in that: the filter body is of a cylindrical structure and consists of a metal filter screen and a condensation type filter element, the condensation type filter element is positioned in the metal filter screen, the upper end of the filter body is provided with a high-efficiency fan, the high-efficiency fan comprises a motor and an impeller, and the impeller is connected with a rotating shaft of the motor; the impeller is positioned at the upper end of the filter body, the impeller is positioned in the exhaust channel, the side wall of the filter box is provided with an air inlet, a filter screen is arranged on the air inlet, oil mist gas enters the filter box through the air inlet, and is filtered by the filter body and then is exhausted from the exhaust channel; the technical scheme is further explained as follows: the lower end of the filter body is provided with a liquid collecting barrel, and the bottom of the liquid collecting barrel is provided with an automatic drain valve; the technical scheme is further explained as follows: an air outlet of the air exhaust channel is provided with an air exhaust high-efficiency filter; the technical scheme is further explained as follows: a differential pressure gauge is arranged on the filter box; the technical scheme is further explained as follows: a circle of isolation plate is arranged on the periphery of the motor in the filter box, the motor is positioned in a sealing cavity formed by the isolation plate and the sealing plate, and a rotating shaft of the motor penetrates through the sealing plate to be connected with the impeller; the technical scheme is further explained as follows: the metal filter screen is a stainless steel wire mesh; the technical scheme is further explained as follows: the filter box is provided with a controller, and the controller is provided with a work timing instrument and an ultrahigh pressure alarm lamp.
