Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to an oil mist filter with an easy-to-replace filter element. Background Art

[0002] Atomization is the process of converting mechanical energy into surface energy of liquid droplets. Due to the violent impact of the liquid on the fixed and rotating units in the machine tool system, it is broken into small droplets floating in the working environment. Evaporation occurs because a large amount of heat is generated in the cutting area. This heat is transferred to the cutting fluid, making its temperature significantly higher than the saturation temperature. Boiling occurs on the contact surface and steam is generated. This steam will then condense around small droplets or other particles in the surrounding air to form oil mist.

[0003] During the CNC machine tool processing process, a large amount of oil mist containing polyaminobiphenyls is generally generated, which not only implicitly damages the physical and mental health of workers, but also poses a health hazard if 2-10 micron particles are inhaled into the human body. In addition, the oil mist is deposited in the work area, which can easily cause work-related injuries and other accidents.

[0004] At the same time, the large amount of oil mist generated by high-speed cutting, which is adsorbed on equipment and workpieces for a long time, may cause malfunctions in the machine tool and electrical systems. This brings considerable trouble to machine tool maintenance and significantly reduces the machine tool's processing precision. In addition, the long-term accumulation of oil mist on walls and equipment poses a potential fire hazard. If the oil mist is discharged outdoors, it will damage the environment. If it can be effectively recovered, it can save resources.

[0005] Therefore, during the CNC machine tool processing, an oil mist filter is used to promptly deal with the oil mist generated during the machining process. The oil mist filter separator is a device that can solve workshop environmental problems such as oil mist, water mist or dust in mechanical processing. It is generally used in CNC machining centers, cleaning machines, die-casting machines, CNC lathes and other types of machining equipment to remove oil mist in the machining chamber, purify the air and protect the health of workers.

[0006] However, when some oil mist filters are actually used to filter a large amount of oil mist containing polychlorinated biphenyls generated during machining, when the filter element assembly inside the filter is regularly replaced, since the interior of the filter is generally in a closed state, a large number of accessories outside the filter need to be removed during the replacement process before the filter element assembly inside the filter can be removed and replaced. The replacement process is relatively cumbersome, time-consuming and labor-intensive, and has shortcomings, making it inconvenient to quickly replace the filter element assembly inside the oil mist filter.

[0007] Now, a novel oil mist filter that is easy to replace the filter element is proposed to solve the above-mentioned shortcomings. Utility Model Content

The protective cover 6 can be provided to provide auxiliary outer cover protection for the outside of the filter, resist external collisions, and provide anti-collision protection for the outside of the filter.

[0036] Openings 23 are respectively provided inside the lower partition 8 and the upper partition 12. An exhaust fan 16 is installed and fixed at the top of the interior of the box body 1. A fresh air outlet 18 is provided inside the top of the box body 1, and a first partition 17 is fixed inside the fresh air outlet 18. An air inlet 26 is provided inside the bottom end of the right side of the box body 1, and a second partition net 27 is fixed inside the air inlet 26.

A valve is fixed on the left side of the oil drain pipe 2.

[0037] Working principle: When the filter of the present invention is in use, the exhaust fan 16 is controlled by the control panel 30 to start suction. After the oil mist is drawn in from the air inlet 26, it first passes through the primary filter 3 to perform auxiliary filtration on the large particles of impurities contained in the oil mist, and then passes through the primary filter element 4 for primary filtration, and the secondary filter element 11 for secondary filtration. During the primary and secondary filtration, after the oil mist enters, the internal suspended particles will collide with the internal filter element fibers. At the same time, the oil mist particles will form larger droplets when flowing along the internal glass fibers, and will drip due to gravity, and eventually flow into the interior of the oil storage tank 28 for collection, and finally reach the top and undergo tertiary adsorption filtration by the tertiary filter element 15 to filter out the fine particles and untreated water vapor in the oil mist. After the tertiary filtration, it is driven by the exhaust fan 16 to be harmlessly discharged from the fresh air outlet 18. When replacing the filter element assembly inside the oil mist filter, turn off the power of the filter, and then respectively move the two sets of locking rods 32 to After the sealed box door 29 is unlocked and opened to the left at the front end of the box body 1, the primary filter 3 and the first-stage filter element 4 can be respectively pulled forward from the interior of the box body 1 by using the first plug-in block 7 at the front end of the box body 1, and then the secondary filter element 11 is pulled forward by using the second plug-in block 9, and the tertiary filter element 15 is pulled forward by using the third plug-in block 14, so that the filter element assembly inside the filter can be quickly disassembled and replaced. The drawer-type replacement method is used. At the same time, when the top control panel 30 at the front end of the filter is in use, a front cover 34 is hingedly installed at the front end of the control panel 30. The front cover 34 can be used to provide an auxiliary cover to the front end operation and display area of the control panel 30 to prevent accidental touch. Before the oil mist filter is used, the protective cover 6 can be fixed to the outside of the box body 1 at the rear end of the outside of the box body 1 using the mounting bolts 25. The protective cover 6 provided can provide an auxiliary outer cover protection for the outside of the filter to resist external collision.
