Dust collector for oil mist

The present invention relates to a dust collector for oil mist.

In general, numerically controlled automatic machine tools are essential for cooling, lubrication, and cleaning in machining processes such as cutting, turning, or grinding, and various mineral oils or water-based or oil-based detergents are widely used.

This oil mist not only causes deterioration of the working environment as described above, but also acts as a factor in fatal failures such as malfunction or short circuit of precision numerical control machine tools. has been developed and is being used.

An apparatus for removing oil mist uses an electric dust collector, a fiber bed filter, or centrifugal filters using centrifugal force generated by rotating a drum having a blower blade and a filter on the outer peripheral surface at high speed.

However, since these dust collectors are provided with additional components such as a high-speed rotating drum having a discharge device or a filter, manufacturing costs are relatively high, and there are many problems such as high maintenance cost of the device, and low processing efficiency.

In addition, the conventional dust collector for oil mist removal operates a fan to suck air into the dust collecting housing through the suction duct, passes through the filter, and then discharges the filtered air through the discharge duct. There were problems in that the cost of replacing the filter occurred because the filter was filtered, and the oil mist could not be removed during the filter replacement, making it difficult to manage the work.

In addition, the conventional dust collector for oil mist removal has a problem in that it is difficult to stably maintain the dust collecting efficiency because the dust collecting efficiency is lowered when the oil mist filtered through the filter is accumulated.

In addition, the first partition wall member 1100 and the second partition wall member 1200 have a structure in which the width can be adjusted in the horizontal direction, and in more detail, the first partition wall member 1100 and the second partition wall member 1200 are It includes a base wall 900a and an insertion wall 900b movably inserted in the width direction into the base wall 900a, respectively.

The first bulkhead member 1100 and the second bulkhead member 1200 include a base wall 900a and an insertion wall 900b, respectively, and can be adjusted in length in the width direction so that the elevating body 1320 is a housing for dust collection. It should be noted that it may be closely attached to the inner surface of the unit 100 or spaced apart from the inner surface of the housing unit 100 for dust collection.

The position of the first partition wall member 1100 or the second partition wall member 1200 is fixed while the elevating body part 1320 is attached to the inner surface of the dust collection housing part 100 by the magnetic force of the electromagnet part 1340. When the elevating traveling unit 1330 is inserted into the compressed state of the spring member 1350 within the wheel inserting unit 1320a, it is positioned.

And, when the electric power supply to the electromagnet unit 1340 is cut off and the magnetic force is released, the elevating traveling unit 1330 protrudes from the wheel inserting unit 1320a by the elastic restoring force of the spring member 1350 while elevating the elevating body portion ( 1320) is spaced apart from the inner surface of the housing unit 100 for dust collection, and thus the first bulkhead member 1100 or the second bulkhead member 1200 can be raised and lowered by the operation of the elevating travel unit 1330. .

In addition, in the first bulkhead member 1100 and the second bulkhead member 1200, when the elevating body part 1320 is in close contact with the inner surface of the dust collecting housing part 100, respectively, the outside of the elevating rail part 1310 A flange portion 1360 for sealing that is supported on the side and prevents oil mist from flowing into the elevating rail portion 1310 is positioned to protrude.

The flange portion 1360 for sealing is positioned to protrude from the front and rear surfaces of the first partition wall member 1100 and the front and rear surfaces of the second partition wall member 1200, respectively, so that the elevating body portion 1320 is the electromagnet portion 1340. When in close contact with the inner surface of the housing unit 100 for dust collection by the magnetic force of the support on the outer surface of the elevating rail unit 1310 prevents the oil mist from flowing into the elevating rail unit 1310.

In addition, the sealing flange portion 1360 has a sealing packing member (1370) that is in close contact with the outer surface of the elevating rail portion 1310 to seal between the sealing flange portion 1360 and the elevating rail portion 1310. is located

The sealing packing member 1370 is positioned on the sealing flange part 1360 in mutual directions so that when the lowering body part is in close contact with the inner surface of the dust collecting housing part 100 by the magnetic force of the electromagnet part 1340, the elevating rail part While in close contact with the outer surface of the 1310, it seals between the sealing flange portion 1360 and the elevating rail unit 1310 to completely block the inflow of oil mist into the elevating rail unit 1310.

That is, the electromagnet unit 1340 serves as a lock to fix the adjusted height of the first bulkhead member 1100 or the second bulkhead member 1200 , as well as a sealing flange part 1360 and a sealing packing member 1370 . ) serves to block the inflow of oil mist into the elevating rail unit 1310 through.

Accordingly, the oil mist does not flow into the elevating rail unit 1310, so the bulkhead elevating unit 1300 can prevent failure due to oil mist flowing into the elevating rail unit 1310, and the first bulkhead member 1100. Alternatively, the second partition wall member 1200 may be stably raised and lowered for a long period of time.

The present invention can effectively remove oil mist by using centrifugal force without a filter, greatly reducing maintenance costs and time, and ensuring stable oil mist dust collection efficiency.

According to the present invention, oil mist is collected by dropping it onto water, and the oil mist accumulated on the water can be removed with the oil skimmer (1000), thereby securing convenience for post-dusting treatment of oil mist and improving the dust collection efficiency of oil mist. can be improved

According to the present invention, oil mist can be more effectively removed without a filter through a plurality of passage walls, and the oil mist is collected by controlling the size of the passage through which air passes according to the particle size and amount of oil mist by raising and lowering the oil mist. efficiency can be maximized.

It should be noted that the present invention is not limited to the above-described embodiments, and can be implemented with various modifications without departing from the gist of the present invention, which is included in the configuration of the present invention.
