The inlet 13 of the oil mist removing device 100 can be connected with a machine, and oil mist waste gas generated by the machine is led into the cavity 11 of the oil mist removing device 100 through the inlet 13. The oil mist deoiling device 100 is simple in structure and convenient to maintain.
Referring to fig. 2 and 3, the oil mist removing device 100 further includes a plurality of baffles 20, a filter screen 30 and a scroll blower 40 disposed in the cavity 11, wherein the baffles 20, the filter screen 30 and the scroll blower 40 are disposed in sequence along a direction from the inlet 13 to the outlet 15, i.e. from bottom to top. The oil mist enters through the inlet 13, then passes through a plurality of baffles 20, a filter screen 30 and a scroll fan 40 in sequence, and finally is discharged from the outlet 15.
A plurality of baffles 20 are fixed to the wall of the chamber 11. Each baffle 20 is bent and extended from the inlet 13 to the outlet 15, and every two adjacent baffles 20 are arranged at intervals. In this application, as shown in fig. 4, each baffle 20 extends vertically upward (toward the outlet 15) and then bends.
The filter screen 30 is detachably inserted into the cavity 11 from the outside of the housing 10. The filter screen 30 comprises a woven metal mesh (e.g., stainless steel mesh) effective to capture the greasy dirt particles from the oil mist after passing through the baffle 20. In the embodiment of the present application, the thickness of the filter screen 30 is 20 mm, but not limited thereto.
As shown in fig. 2, the scroll blower 40 includes a scroll 41 and a blower 43 rotatably disposed inside the scroll 41. The scroll blower 40 is at least partially aligned with the outlet 15 to discharge the agitated exhaust gas through the outlet 15.

As shown in fig. 4, filter screen 30 includes an upper end 31 and a lower end 33 opposite upper end 31, wherein lower end 33 is closer to inlet 13 than upper end 31. That is, the filter screen 30 is inclined, and the height direction upper and lower ends 33 are lower than the upper end 31. The filter screen 30 is obliquely arranged in such a way, so that the greasy dirt on the filter screen 30 can be gradually transferred to the position of the lower end 33 by means of gravity for collection. An oil collecting pipe (not shown) may be provided at the position of the lower end 33 of the filter screen 30 to guide out the oil dirt collected at the lower end 33.

The limiting plate 34 is connected with a handle 35 to facilitate pulling the filter screen 30. When the filter screen 30 is installed, the lower end 33 of the filter screen 30 is aligned with the installation hole 17, and then the filter screen 30 is inserted into the cavity 11 in a sliding manner along the guide rail 18 until the limiting plate 34 abuts against the shell 10 and the filter screen 30 cannot slide continuously, and the upper end 31 of the filter screen 30 is located at the position of the installation hole 17.
As shown in fig. 4, the position of the scroll casing 41 facing the inlet 13 is provided with an oil leakage hole 42, and the oil leakage hole 42 is preferably provided at the lowest point of the scroll casing 41. In this way, the oil droplets thrown onto the scroll casing 41 by the centrifugal action of the fan 43 slowly accumulate on the scroll casing 41 and then flow out through the oil leakage hole 42.
Referring to fig. 3 and 4 in combination, a flat baffle 50 is also disposed between the scroll blower 43 and the filter screen 30, the baffle 50 including opposite first and second ends 51, 53, wherein the first end 51 is fixed in position at the lower end 33, the second end 53 is suspended in the cavity 11, and the first end 51 is closer to the inlet 13 than the second end 53. That is, the deflector 50 is disposed obliquely, and the first end 51 is lower than the second end 53 in height, so that the oil dirt on the deflector 50 can be collected in the direction of the first end 51 by gravity. The area size of the deflector 50 is smaller than that of the filter screen 30, the deflector 50 partially covers the filter screen 30, and the oil mist waste gas passing through the filter screen 30 bypasses the deflector 50 and enters the volute fan 43.
In addition, as shown in fig. 2 to 4, an arc plate 60 is further provided on the side of the scroll fan 40 near the inlet 13, and the arc plate 60 partially surrounds the scroll 41 of the scroll fan 40. The oil leakage holes 42 are aligned with the arcuate plate 60, and the arcuate plate 60 is at least partially aligned with the baffle 50. Thus, the oil droplets flowing out through the oil drain holes 42 flow onto the arc plate 60, then onto the flat-plate-shaped baffle 50, and finally into the oil collecting pipe at the position of the lower end 33 by gravity.
As shown in fig. 2 and 3, a partition 70 is further provided in the chamber 11, and the partition 70 is provided between the scroll fan 40 and the outlet 15. The baffle 70 includes opposing first and second surfaces 71, 72, wherein the first surface 71 faces away from the outlet 15 and the second surface 72 faces toward the outlet 15. The scroll fan 40 is fixedly mounted to a side of the partition 70 having the first surface 71.
The partition 70 is provided with an opening 73 at least partially aligned with the scroll fan 40 and the outlet 15 so that exhaust from the scroll fan 43 can be discharged through the outlet 15 after passing through the opening 73. The second surface 72 of the diaphragm 70 is provided with a ring of oil rims 77 surrounding the opening 73. Although most of the oil stains are intercepted by the baffle plate 20, the filter screen 30 and the volute fan 43, as the service time of the oil mist deoiling device 100 increases, some oil stains can be accumulated slowly when the positions of the baffle plate 70 and the outlet 15 are out, the oil baffle edge 77 can effectively prevent the oil stains above the baffle plate 70 in the cavity 11 from accumulating and falling back onto the filter screen 30, and the oil baffle edge 77 only enables the oil stains to be on the second surface 72.
In addition, as shown in fig. 2, the partition plate 70 is further provided with an oil drain hole 75 penetrating therethrough, the oil drain hole 75 is connected with a flow guide 78, and the flow guide 78 is connected to the first surface 71 of the partition plate 70 and aligned with the flow guide plate 50. Thus, by the matching arrangement of the oil baffle edge 77 and the guide pipe 78, the oil dirt collected on the second surface 72 of the partition plate 70 can drop onto the guide plate 50 through the oil drain hole 75 and the guide pipe 78 and finally flow into the oil collecting pipe at the position of the lower end 33; and further, the oil dirt can not drop on the filter screen 30, so that the maintenance frequency of the filter screen 30 can be effectively reduced.

The scroll fan 40 may be fixedly mounted to the partition 70 and the wall of the chamber 11 by fasteners (not shown). The shock pad 80 is arranged at the position of the fastening piece, so that the influence of vibration on the machine table and the oil mist degreasing device 100 during operation of the oil volute fan 40 can be effectively reduced.
The oil mist eliminator 100 may also be provided with an oil collecting funnel (not shown) provided at a position of the baffle plate 20 near the inlet 13. Thus, the oil dirt collected at the lower end 33 of the baffle plate 20 is recovered by the oil collecting hopper, and the oil dirt is prevented from flowing back to the inlet 13 to influence the operation of the machine.
As shown in fig. 3 and 4, the oil mist removing device 100 further includes a mounting plate 90, the mounting plate 90 surrounds and is connected to the housing 10, and the mounting plate 90 is mounted on a machine table by fasteners to mount the oil mist removing device 100 on the machine table. The shock pad 80 is arranged at the position of the fastener, so that the influence of vibration on the machine when the oil mist deoiling device 100 operates can be effectively reduced.
