Oil mist recovery device

Abstract

The invention discloses an oil mist recovery device. An air inlet pipe is arranged on the side face of a shell, an air outlet is formed in the top face of the shell, a front air cavity and a rear air cavity which are communicated are formed in the shell, the front air cavity is communicated with the air inlet pipe, and the rear air cavity is communicated with the air outlet; and a fan is arranged in the rear air cavity, the periphery of the fan is sleeved with a housing, and a buffering cavity is formed between the housing and the fan and communicated with the rear air cavity. The housing is arranged outside the fan, on one hand, the housing provides a protection effect for the fan, the fan is prevented from being exposed under the air outlet, oil liquid, water liquid or dust and the like are prevented from entering the fan, internal elements of the fan are protected, and the service life of the fan is prolonged; on the other hand, the buffering cavity is formed in the periphery of the fan, airflow from the fan firstly enters the buffering cavity, is uniformly distributed in the buffering cavity and then flows into the rear air cavity from the air outlet channel, and the distribution uniformity of the airflow is better improved.

Description

technical field [0001] The invention relates to the technical field of air oil mist purification and recovery, in particular to an oil mist recovery device. Background technique [0002] During machining operations, it is often necessary to use various cutting oils or coolants to lubricate the tool and reduce the processing temperature of the workpiece, which will generate a large amount of oil mist, dust, oil smoke and smog in the working environment, causing physical fatigue of the operators on site. harm. The oil mist collector is mainly used to collect the oil mist, water mist or dust generated in mechanical processing, and through interception and filtration, the harmful substances in it are removed, and the metal cutting oil and other materials with recycling value are regenerated. Recycled, and finally discharged clean gas. [0003] Existing oil mist collectors usually have horizontal suction and horizontal gas outlet, that is, the gas is sucked in from the front si...

Problems solved by technology

[0006] (1) The air guide port of the oil mist recovery machine is located on the top of the second air chamber and directly connected to the second air chamber. After the gas is inhaled from the first air chamber, it is directly pushed upward into the second filter unit. The flow path of the air chamber is short, the residence time is short, the air conduction in the second air chamber is not uniform enough, and the utilization of the wind is still not sufficient;

[0007] (2) The turbine guide fan is directly exposed directly under the second filter unit, and the oil, water or dust filtered out by the second filter unit can easily enter the turbine guide fan, corroding or wearing the internal components of the turbine guide fan , affecting the service life of the turbo guide fan

[0008] The oil storage tank of the existing oil mist collector is set at the bottom of the frame, which is inconvenient to replace or clean the oil storage bottle
