Description

Technical Field

[0001] The utility model relates to the technical field of separation mechanisms, in particular to a vacuum separation mechanism for an oil filter. Background Art

[0002] Vacuum oil filter is also called vacuum high-efficiency oil filter, oil filter and vacuum oil purifier. The vacuum oil purifier is designed based on the different boiling points of water and oil. The vacuum pump draws out the air in the vacuum tank to form a vacuum. Under the action of atmospheric pressure, the external oil enters the primary filter through the inlet pipe and then enters the heating tank. The heated oil is separated into semi-mist by the rapid rotation of the spray wing. The water in the oil evaporates rapidly into water vapor and is continuously sucked into the condenser by the vacuum pump.

[0003] In the prior art, a Chinese patent with publication number CN219836123U proposes a vacuum separation mechanism for a vacuum oil filter, which uses multiple baffles to extend the effective residence time of oil in the tank body, promotes the full separation of oil in the vacuum separation chamber, and uses multiple nozzles for multiple atomization to further improve the oil-water separation effect. However, in actual application, there are still multiple baffles that extend the residence time of oil in the tank body, and also hinder the rapid evaporation of water, so that the water in the oil is not sucked into the condenser by the vacuum pump in time after being separated, thereby causing the water to mix with the oil again, making the oil-water separation effect of the vacuum separation mechanism unsatisfactory. Therefore, we disclose a vacuum separation mechanism for an oil filter. Utility Model Content

[0004] In view of this, the purpose of the utility model is to propose a vacuum separation mechanism for an oil filter to solve the problem that the water in the oil is not sucked into the condenser by the vacuum pump in time after being separated, resulting in the water being mixed with the oil again.

[0005] Based on the above purpose, the utility model provides a vacuum separation mechanism of an oil filter, including a vacuum tank, wherein a plurality of first guide plates are fixedly connected to the inner wall of the vacuum tank, a first support frame and a second support frame are fixedly connected to the middle parts of the upper and lower ends of the first guide plates, respectively, a rotating assembly is arranged in the middle parts of the first support frame and the second support frame, the rotating assembly is used to slow down the descending speed of the oil, and the two ends of the rotating assembly are respectively connected to the first support frame and the second support frame.

[0006] Preferably, the rotating assembly comprises a rotating shaft rotatably connected between the first supporting frame and the second supporting frame, and a plurality of fan blades are fixedly connected to an outer wall of the rotating shaft.

[0007] Preferably, a rotation groove is opened in the middle of the first support frame, and the first limit plate rotatably connected in the rotation groove is fixedly connected to one end of the rotating shaft, and the rotating shaft is rotatably connected in the rotation groove. The rotation groove is a T-shaped groove, and the diameter value of the first limit plate is greater than the diameter value of the rotating shaft.

[0008] Preferably, the plurality of first spheres movably engaged in the rotating groove are all in contact with the outer wall of the first limiting plate.

[0009] Preferably, a rotation hole is opened in the middle of the second support frame, the other end of the rotating shaft passing through the rotation hole is fixedly connected to a second limiting plate, and a plurality of second spheres movably clamped in the middle of the second support frame fit with the outer wall of the second limiting plate.

[0010] Preferably, the plurality of second guide plates fixedly connected between the first guide plates are fixedly connected to the inner wall of the vacuum tank, and the second guide plates are in an inverted V shape.

[0011] Preferably, the vacuum tank is composed of a cylinder in the middle and semicircles at both ends, the first guide plate is vertically arranged relative to the horizontal plane, and the length of the first guide plate is equal to the length of the vacuum tank cylinder.

[0012] The beneficial effects of the utility model are as follows: when the oil is heated and flows into the vacuum tank, and is rapidly rotated into a semi-mist state by the spray wing at the end of the oil delivery pipe in the vacuum tank, the stirred airflow drives the fan blades to rotate, so that the fan blades blow the gas upward, thereby causing the fan blades to slow down the descending speed of the semi-mist oil, thereby prolonging the retention time of the oil in the vacuum tank, and does not affect the water evaporated in the oil being sucked into the condenser by the vacuum pump, so that the water evaporated in the oil can be sucked out of the vacuum tank in time, avoiding the situation where the water gathers in the vacuum tank and mixes with the oil again, thereby ensuring the water separation effect in the oil;

[0013] The oil gathered on the inner wall of the Yaohai vacuum tank adheres to the outer wall of the second guide plate, and is then guided by the second guide plate to the outer wall of the first guide plate, and then falls under the influence of gravity, thereby accelerating the speed at which the oil on the inner wall of the vacuum tank flows out of the inner cavity of the vacuum tank, further reducing the possibility of water separated from the heavy oil mixing with the oil again, thereby ensuring the water separation effect in the oil.

When in use, a plurality of first guide plates 2 are fixedly connected to the inner wall of the vacuum tank 1, and the middle parts of the upper and lower ends of the first guide plate 2 are respectively fixedly connected to the first support frame 3 and the second support frame 4, so that the vacuum tank 1 fixes the first support frame 3 and the first guide plate 2 through the first guide plate 2. The second support frame 4 is located at a position where a rotating assembly is arranged through the middle of the first support frame 3 and the second support frame 4. The rotating assembly includes a rotating shaft 5 rotatably connected between the first support frame 3 and the second support frame 4.

[0025] As a preferred implementation in this embodiment, Figure 3-Figure 5As shown, a rotation groove 7 is provided in the middle of the first support frame 3, and the first limit plate 9 rotatably connected in the rotation groove 7 is fixedly connected to one end of the rotating shaft 5, and the rotating shaft 5 is rotatably connected in the rotation groove 7.
