Problems solved by technology

[0003] (1) In the case of achieving a better uniform spray atomization effect, the required fuel consumption is still relatively large;
[0004] (2) Only when the oil supply reaches a large value can a better uniform spraying effect be achieved, and when the oil supply is lower than a certain value, the atomization effect of the oil is poor, which will lead to The direction of spraying is discontinuous and uniform;
[0005] (3) Better continuous and uniform spraying cannot be achieved in occasions that need to meet the requirements of extremely thin oil film thickness

Embodiment 1

[0026] A knife beam device for an electrostatic oiler. The device as figure 1 and image 3 Shown, this device comprises knife beam left piece 4, plastic film 5 and knife beam right piece 7. The length, width and height of the knife beam left piece 4 are equal to the length, width and height of the knife beam right piece 7 respectively, and the knife beam left piece 4 and the knife beam right piece 7 are connected by bolts 9. A circulating oil tank 6 is provided on the upper part between the left piece 4 of the knife beam and the right piece 7 of the knife beam. Double "V" shaped oil groove 1. Be provided with plastic film 5 between knife beam left piece 4 and knife beam right piece 7, plastic film 5 is positioned at the rectangular oil tank 2 top except circulating oil tank 6. The gap between the left piece 4 of the knife beam and the right piece 7 of the knife beam below the rectangular oil tank 2 is 0.1 to 0.2 mm , The two ends of knife beam left piece 4 and knife bea...

Embodiment 2

[0035] A knife beam device for an electrostatic oiler. This device is except following technical parameter, all the other are with embodiment 1:

[0036] l 1 = 0.018~0.02 l ; l 2 = 0.030~0.035 l ; l 3 = 0.25~0.3 l 0 ; l 4 = 0.28~0.37 l 0 ; The centerline distance between rectangular oil groove 2 and double "V" shaped oil groove 1 is 5~6 mm .

[0037] The gap between the knife beam left piece 4 and the knife beam right piece 7 of this specific embodiment is controlled by the thickness of the plastic film 5, and its gap is 0.1 ~ 0.2 mm . The knife beam baffle plate 8 is to prevent the working oil from overflowing from both ends of the knife beam device; the circulating oil tank 6 can preheat the knife beam device and the oil when the ambient temperature is low, which is beneficial to the working oil Smooth flow; the width of the rectangular oil tank 2 is smaller than the diameters of the first working oil inlet 10 and the second working oil inlet 13, so th...

Abstract

The invention relates to a blade device for a static oiling machine. The technical scheme is as follows: the device comprises a left blade piece (4), a plastic thin film (5) and a right blade piece (7). The left blade piece (4) and the right blade piece (7) are coupled through a bolt (9). A circular oil groove (6) is arranged at the upper part between the left blade piece (4) and the right blade piece (7). A rectangular oil groove (2) is arranged at the lower part between the left blade piece (4) and the right blade piece (7). A double V-shaped oil groove (1) is arranged below the rectangular oil groove (2). The plastic thin film (5) is arranged between the left blade piece (4) and the right blade piece (7) and located above the rectangular oil groove (2) outside the circular oil groove (6). The gap of the blade device below the rectangular oil groove (2) is 0.1-0.2mm. Blade baffles (8) are respectively arranged at both ends of the left blade piece (4) and the right blade piece (7). The blade device has the advantages of good spraying effect and low oil consumption under low oil supply, and the thickness of the oil film is below 60 microns.

Description

technical field [0001] The invention belongs to the technical field of an electrostatic oiler, and in particular relates to a knife beam device for an electrostatic oiler. technical background [0002] At present, electrostatic spraying mostly adopts knife-beam electrostatic atomization device, which has good spraying quality, uniform spraying and low fuel consumption, which overcomes the defects of uneven spraying, strip-shaped missing coating and large waste of oil in other devices. "Electrostatic oiling device" (ZL98232316.6) discloses that increasing the voltage of the knife beam is an effective way to increase the electric field strength, so as to achieve the purpose of improving the atomization effect of the oil; "Electrostatic oiling machine atomization knife beam Improved structure" (201020144406) is to improve the spraying effect by changing the cross-sectional shape of the oil groove inside the knife beam to prevent the gap inside the knife beam from being blocked....
