Description
Technical field
The present invention relates to a kind of changeable positive and negative mist of oil recover, belong to field of environment protection equipment.
Background technology
The course of work of metal working lubricant determines that its mist of oil generation form contains machinery, physics and physics one and changed
Mode exists simultaneously.In order to effectively lubricate, cool down and clean, metal working lubricant to undergo in use pump circulation,
Spraying, the cutter of jet and rotation at a high speed be fierce to be hit and the process such as high temperature evaporation.Mode caused by mist of oil is different, and its particle is straight
Footpath scope also has larger difference.Generally, mist of oil caused by mechanical atomization process mainly exists with droplet morphology, and drop is straight
Footpath wider range, usually 2~10um.Oil vapour caused by evaporation can also form very tiny cold of diameter in condensation process
Solidifying suspended substance, particle diameter is usually below 2um.Research shows that the maximum distribution of mist of oil particle diameter is 1um in air in workshop, right
The test result of mist of oil particle diameter shows that 95% liquid-drop diameter is less than 3um around grinding machine.A large amount of evaporations of lubricant make processing cart
Between total hydrocarbon content in air it is more much bigger than mist of oil test value.
Metal working lubricant is relevant with a variety of occupational diseases.The known occupational disease for causing the incidence of disease substantially to increase includes
Benign respiratory disease (including asthma, pneumonia etc.), anaphylaxis dermatosis and malignant tumour.Using animal as subjects
Result of study shows that dog contacts 5~100mg/m3 mist of oils more than 12 months, and fatty alveolar and macrophage fat occurs
Property granuloma, and there is the feature of morphologic change in respiratory tissue.Someone in 1996 is to one ball using emulsion in the U.S.
166 workers of bearing mnanufacture factory have carried out asthma investigation, and the oil mist concentration for as a result showing to work as in workshop is 0.65rng/m3
When, often in contact with thering is 4% to suffer from asthma in the worker of metal working fluid mist of oil；And it is not in contact with working fluid in same factory
In the worker of mist of oil, it is zero to suffer from asthma number.Statistics bureau of Ministry of Labour of the U.S. issue dermatergosis survey report also indicate that,
The dermopathic average attack rate of full-time worker is 0.77 ‰ within 1991；And the same year rigging screw and standard machinery processing industry
The incidence of disease is respectively 3.33 ‰ and 2.22 ‰, and the two industries are also oil mist concentration highest industry in working environment.
Therefore, reduce workshop in mist of oil can effective guarantee workers ' health, reduce the corrosion to equipment, existing mist of oil
The retracting device such as patent No.：CN106823595A discloses a kind of mist of oil recycling machine, including frame, and frame is provided with housing, described
The side of housing is provided with entrance, and the first level filtering device for carrying out by-pass filtration to mist of oil is sequentially provided with the housing, uses
In the two-stage filter that secondary filtration is carried out to mist of oil, for carrying out three-level filter device and the drive of three-stage filtration to mist of oil
Motivation structure, the drive mechanism and three-level filter device drive connection；The lower end of the three-level filter device is provided with collecting mechanism.
Although the invention can realize multiple mistake to mist of oil by first level filtering device, two-stage filter and three-level filter device
The effect of filter, taste removal processing and mist of oil cooling liquid recovery；But the inventive structure is complicated, screen pack needs easy long-pending oil, needs
Frequently to change, and air flux is small, and filter effect is bad.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of changeable positive and negative mist of oil recover.Structure of the present invention
Simply, mainly mist of oil is gathered into liquid using centrifugal action, filtering web service life length, without frequently changing, and filter effect
Fruit is good, and air flux is big, and filter efficiency is high, can realize the air inlet outlet of different directions by the rotating of motor in addition, from
And wherein a filter cotton cylinder long-pending oil when without changing immediately, only need to invert motor can be done as usual using another filter cotton cylinder
Work, and during filter cotton cylinder is replaced and cleaned, recover can still realize that mist of oil reclaims as usual.
