Oil mist collector for precision mechanical processing factory

Abstract

Belonging to the technical field of oil mist collecting equipment, the invention discloses an oil mist collector for a precision mechanical processing factory. The oil mist collector for a precision mechanical processing factory comprises a machine shell, the left half of the machine shell is cylindrical, an air suction pipe and an air outlet pipe are arranged on the left side and right side of the machine shell respectively, the position of the air outlet pipe is communicated with the inlet of an HEPA filter, the inner wall of the machine shell is fixedly connected to the side wall of a mounting disc through a connecting rod, the mounting disc is parallel to the left and right side faces of the machine shell, a motor is fixedly mounted on the right side of the mounting disc, a motor output shaft runs through the mounting disc to the left side and is fixedly sleeved with an impeller, a primary filtering mechanism is arranged at the left half in the machine shell, and the left end faceof a filter cartridge is fixedly connected to the right side face of the mounting disc and outside the motor. Through improvement of the primary filtering mechanism, the oil mist collector for a precision mechanical processing factory greatly increases the oil collecting speed, and can avoid the problem that the blockage of a primary filtering net affects the oil collecting efficiency.

Description

technical field [0001] The invention relates to the technical field of oil mist collection equipment, in particular to an oil mist collector for precision machinery processing plants. Background technique [0002] The processing of precision parts by machine tools often involves cutting processing. The formation of metal cutting fluid oil mist during processing can be mainly attributed to two mechanisms, atomization and evaporation: atomization is the process of converting mechanical energy into droplet surface energy. Mainly due to the violent impact of the liquid on the fixed and rotating units in the machine tool system, it is broken by it, forming fine droplets floating in the working environment; evaporation occurs because a large amount of heat is generated in the cutting area, and the heat is transmitted to the cutting fluid to make it Its temperature is significantly higher than the saturation temperature, and boiling occurs on the solid-liquid contact surface and st...

Problems solved by technology

[0003] The oil mist generated during the processing will cause great pollution to the working environment and pose a greater threat to the health of the staff. Therefore, the collection of oil mist is very necessary. The existing oil mist collection devices are usually made of The impeller of the motor rotates to form a negative pressure, and 1-3 layers of filters are set to filter the oil, and the oil is flowed down by gravity to complete the collection of the oil mist, but the oil mist generated during the processing often contains metal powder generated by cutting, which will increase The viscosity of the oil mist is not easy to flow down from the filter screen, and the filter screen will be blocked, which will affect the collection rate of oil mist
