Oil mist recovery machine

This creation is about an oil mist recovery machine, especially an oil mist recovery machine for processing machines.

In the processing of large lathes such as lathes, milling machines or drill presses, most of them must use cutting oil to assist the heat dissipation during the cutting process and improve the surface quality after cutting. Therefore, the processing machine will inevitably produce oil after cutting operations. A misty exhaust gas. Therefore, the manufacturer will add an oil mist recovery machine on the processing machine to recover the oil mist-like exhaust gas generated by the processing machine, thereby reducing the air quality of the working environment caused by the oil mist, and further filtering the dust in the oil mist. The cutting oil collected by the oil mist is recycled and reused.

The oil mist recovery machine uses the wind of the centrifugal fan to suck the oil mist into the body, so that the filter filters the recyclable cutting oil component, and then waits for the cutting oil to flow down the filter to the oil recovery port at the bottom of the body for recovery. However, the oil mist flow inhaling the body passes through the filter in an axial manner, and the area of the oil mist flow through which the filter passes is only a part of the filter mesh, and the oil mist cannot be effectively filtered in a large area, so that the impurities in the oil mist are concentrated. In the part of the effective filtration area of the filter, when the impurities in the oil mist block the effective filtration area of the filter, the effect of the filter filtration is greatly reduced, and the efficiency of the recovery of the cutting oil is also reduced.

For the above problems, the technology disclosed in the "Oil Mist Recovery Machine" of the Republic of China New Patent Publication No. M367750 can increase the filtration area of the filter for filtering oil mist, greatly increase the filtration effect of the filter, and also increase the recovery of cutting oil. effectiveness. However, the cutting oil accumulated around the inner wall of the body of the novel case will permeate the outside of the oil mist recovery machine at the rubber gasket between the body and the oil collection chamber, thereby reducing the efficiency of recovering the oil mist and causing oil mist. Dirty outside the recycling machine.

In view of the above problems, the object of the present invention is to provide an oil mist recovery machine which can recover the cutting oil oozing from the rubber gasket between the body and the oil collection chamber, thereby increasing the efficiency of recovering the oil mist, and thus does not cause oil. Dirty outside the fog recycling machine.

The aspect of the present invention provides an oil mist recovery machine, which comprises a body, a rubber gasket and an oil storage chamber, the body is mounted on the oil storage chamber, and the rubber gasket is placed on the body and the storage Between the oil chambers, the outer periphery of the mounting surface of the oil storage chamber forms an upwardly bent surrounding portion, the body is mounted on the mounting surface of the oil storage chamber, and is placed in the oil storage chamber Among the surrounding portions, an oil groove is formed in a space between the outer surface of the body and the surrounding portion of the oil storage chamber.

In FIGS. 1 to 7A and 7B, the oil mist recovery machine 14 includes a body 22, an oil storage chamber 52, a centrifugal fan 28, and a motor 30. The body 22 has a first body 24 and a second body 26, and the first body 24 and the second body 26 respectively form separate spaces.

A suction hole 32 is formed on the front side of the first body 24. A plurality of exhaust holes 34 are formed above the second body 26. A first oil drain hole 54 is defined in the oil reservoir 52 below the first body 24, and a second oil drain hole 56 is formed in the oil reservoir 52 below the second body 26. The centrifugal fan 28 is mounted inside the first body 24. The motor 30 is mounted outside the first body 24 and is located at a recessed position 50 outside the second body 26.

The first body 24 and the second body 26 are mounted side by side on the mounting surface of the oil storage chamber 52. A rubber gasket 53 is placed between the first body 24 and the second body 26 and the oil storage chamber 52. A rubber gasket 53 is formed between the first body 24 and the mounting surface of the oil reservoir 52 to form an aperture 55.

The outer periphery of the mounting surface of the oil storage chamber 52 forms an upwardly bent surrounding portion 58. The first body 24 and the second body 26 are mounted on the mounting surface of the oil storage chamber 52 and placed in the oil storage chamber 52. In the surrounding portion 58, an oil groove 60 is formed in a space between the outer surfaces of the first body 24 and the second body 26 and the surrounding portion 58 of the oil reservoir 52.

The motor 30 drives the centrifugal fan 28 to rotate such that a negative pressure is generated at the suction hole 32 of the first body 24 to suck the oil mist in the processing machine into the first body 24, and at the exhaust hole 34 of the second body 26. A positive pressure is generated to discharge the airflow in the second body 26 through the filtered oil mist out of the second body 26.

A spoiler (not shown) and a first filter 40 are disposed in the first body 24. The spoiler and the first filter 40 are mounted at an axial position of the suction hole 32 of the first body 24 and sucked into the airflow containing the oil mist.

When the airflow containing the oil mist is sucked by the suction hole 32 and passes through the spoiler and the first filter 40, the first filter 40 filters the oil mist of the part of the cutting oil, and the oil mist filtered by the first filter 40 gathers. After cutting the oil, it will flow down the first filter 40 to a first space of the oil storage chamber 52 below a portion of the corresponding first body 24. In 62, the cutting oil flows out from the first oil drain hole 54 of one of the oil storage chambers 52 and is recycled.

A second filter (not shown) is attached to the inner peripheral surface of the blades of the centrifugal fan 28. A second space 64 is formed in the oil reservoir 52 below the second body 26 below the other portion of the first body 24, and a second oil drain hole 56 is formed in the second space 64.

Due to the rotation of the centrifugal fan 28, a negative pressure is generated inside the first body 24, so that the airflow passing through the first filter 40 containing a part of the oil mist continues to flow through the second filter installed inside the centrifugal fan 28, so that the second filter can be The filter filters the oil mist in the gas stream.

Since the second filter is mounted on the inner peripheral surface of the blades of the centrifugal fan 28, the second filter also rotates with the centrifugal fan 28. After the oil mist filtered by the second filter is gathered into the cutting oil, the cutting oil is blown around the inner wall of the first body 24 by the centrifugal force generated by the rotation of the second filter, and adheres to the inner wall of the inner wall. The cutting oil attached to the periphery of the inner wall gathers the oil droplets and flows down to the bottom of the first body 24, and then flows to the second space 64 of the oil storage chamber 52 below the corresponding first body 24 to flow to the oil storage. Oil droplets (i.e., cutting oil) in the second space 64 of the chamber 52 flow out through the second oil drain hole 56 of the oil storage chamber 52 and are recycled.

However, when the oil droplets collected around the inner wall of the first body 24 flow to the rubber gasket 53 between the first body 24 and the oil reservoir 52, the oil droplets may seep out from the rubber gasket 53. Since the space between the outer surface of the first body 24 and the second body 26 and the surrounding portion 58 of the oil reservoir 52 forms the oil groove 60 (as shown in FIG. 1B), the oil droplets oozing from the rubber gasket 53 will It flows into the oil groove 60, and does not flow to the outside of the oil mist recovery machine 14, and it is prevented from being dirty outside the oil mist recovery machine 14.

The oil droplets flowing into the oil groove 60 flow to the pores 55 of the rubber gasket 53 (as shown in FIG. 4, FIG. 7A and FIG. 7B), and since the inside of the first body 24 is a negative pressure, the oil droplets will be The inside of the first body 24 is sucked from the oil groove 60 at the aperture 55, and the oil droplets sucked into the inside of the first body 24 flow down to the bottom of the first body 24, and then flow to the oil storage chamber below the corresponding first body 24. The second space 64 of the 52, the oil droplets flowing to the second space 64 of the oil storage chamber 52 flow out through the second oil drain hole 56 of the oil storage chamber 52 and are recycled.

The present invention provides an oil mist recovery machine, which is characterized in that the cutting oil which is oozing out from the rubber gasket between the body and the oil collection chamber is recovered, and the efficiency of recovering the oil mist is increased, so that the outside of the oil mist recovery machine is not caused. Dirty.
