Description

Technical Field

[0001] The utility model relates to the field of fluid purification, in particular to an oil-gas separator driving device and an oil-gas separator. Background Art

[0002] A gas-liquid separator is a device that uses the principle of centrifugal force to separate gas and liquid, achieving liquid removal. It can be used to separate gas-liquid mixtures emitted by automobile engines. The driving oil for the gas-liquid separator comes from the engine lubricating oil. Because some engines use oil from the oil filter as the driving oil for the gas-liquid separator, and the lubricating oil pressure before the oil filter is high, the gas-liquid separator's rotation speed exceeds the limit. Excessive rotation speed reduces the gas-liquid separator's service life. Utility Model Content

[0003] In order to overcome the defects in the prior art, the utility model provides an oil-gas separator driving device, the inner diameter of the nozzle of the device increases from its outlet end to its inlet end, and a plurality of steps are provided in the nozzle. When the lubricating oil passes through the inner wall of the nozzle, it collides with the steps, causing local loss of energy of the driving oil, reducing the driving oil pressure, and reducing the kinetic energy of the impact driving wheel.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an oil-gas separator driving device for driving the oil-gas separator to rotate, comprising:

[0005] A driving wheel, the driving wheel is sleeved on the central axis of the oil-gas separator, and a plurality of grooves are provided on the circumference of the driving wheel;

[0006] The nozzle has an inlet end connected to a power source, an outlet of the nozzle is arranged toward the inner wall of the groove, an inner diameter of the nozzle increases from the outlet end to the inlet end, and a plurality of steps are arranged inside the nozzle.

[0007] With this technical solution, the nozzle sprays liquid, which impacts the drive wheel, causing it to rotate. Because the nozzle's inner diameter increases from its outlet to its inlet, and because the nozzle is provided with multiple steps, the lubricating oil collides with the steps as it passes through the inner sidewall of the nozzle, partially losing its kinetic energy. This reduces the impact force of the lubricating oil striking the drive wheel, thereby reducing the drive wheel's rotational speed.

[0008] Furthermore, the number of steps within the nozzle ranges from one to four. The number of steps is adjusted based on the driving oil pressure: higher driving oil pressure results in more steps, while lower driving oil pressure results in fewer steps. Currently, four steps are sufficient to achieve the desired pressure reduction and speed reduction requirements for commercially available oil-gas separators, and are relatively simple to manufacture.

[0009] Furthermore, the inner diameter of the nozzle's outlet is between 1.6mm and 3mm. The size of the nozzle's outlet inner diameter is adjusted based on the driving oil pressure. The smaller the inner diameter, the greater the kinetic energy loss of the driving oil. That is, the greater the driving oil pressure, the smaller the inner diameter of the nozzle's outlet; conversely, the smaller the driving oil pressure, the larger the inner diameter of the nozzle's outlet. However, if the inner diameter of the nozzle's outlet is less than 1.6mm, it can easily become clogged by impurities in the driving oil.

[0010] Furthermore, the inner diameter of the nozzle outlet is 2 mm to 2.5 mm. The range of 2 mm to 2.5 mm makes the nozzle outlet less likely to be blocked by impurities in the driving oil, and the driving oil volume is moderate, thereby maximizing the driving efficiency.

[0011] Furthermore, in the radial direction of the drive wheel, the depth of the groove increases from one side to the other, that is, the inner sidewall of the groove is an inclined surface. The nozzle sprays lubricating oil onto the inclined surface, and the lubricating oil hits the deepest part of the groove along the inclined surface, causing the drive wheel to rotate. This design ensures that the nozzle drives the drive wheel to rotate in the same direction.

[0012] Furthermore, the outlet of the nozzle is oriented parallel to the radial direction of the driving wheel, so that the lubricating oil sprayed from the nozzle can directly hit the deepest part of the groove.

[0013] An oil-gas separator using the oil-gas separator driving device comprises:

[0014] A housing, wherein a bearing seat is provided in the housing, and a bearing is provided in the bearing seat;

[0015] an oil-gas separation device, the oil-gas separation device being disposed in the housing, and a central axis of the oil-gas separation device being passed through the bearing;

[0016] The driving wheel is arranged on the central axis of the oil-gas separation device.

[0017] By means of the above technical solution, the beneficial effects of the present invention are as follows:

[0018] 1. In this application, the inner diameter of the nozzle increases from its outlet end to its inlet end, and multiple steps are provided inside the nozzle. When the lubricating oil passes through the inner wall of the nozzle, it collides with the steps, causing the kinetic energy of the lubricating oil to be partially lost, thereby reducing the impact force of the lubricating oil hitting the drive wheel, thereby reducing the speed of the drive wheel;

[0019] 2. In the present application, in the radial direction of the driving wheel, the depth of the groove increases from one side to the other, that is, the inner side wall of the groove is a slope, and the nozzle is arranged parallel to the radial direction of the driving wheel. The nozzle sprays lubricating oil on the slope, and the lubricating oil hits the deepest part of the groove along the slope, causing the driving wheel to rotate. This design ensures that the nozzle drives the driving wheel to rotate in the same direction, while also preventing the driving oil from splashing.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] It should be noted that, in the description of this utility model, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0030] Combine Figure 1-5 As shown, embodiment 1 discloses an oil-gas separator driving device for driving the oil-gas separator to rotate, comprising:

[0031] The driving wheel 1 is used to be sleeved on the central shaft 21 of the oil-gas separator. Figure 2 As shown, a plurality of grooves 11 are provided at equal intervals on the circumference of the driving wheel 1. In the radial direction of the driving wheel 1, the depth of the grooves 11 increases from one side to the other. Figure 2 As shown, the inner side wall of the groove 11 is an inclined surface from left to right and from outside to inside.

[0032] Also includes a nozzle 3, such as Figure 1 As shown, the outlet of the nozzle 3 is oriented parallel to the radial direction of the drive wheel 1 and is located to the right of this radial line. The nozzle 3 sprays lubricating oil onto the inclined surface within the groove 11. The lubricating oil flows along the inclined surface and strikes the deepest part of the groove 11, causing the drive wheel 1 to rotate the central axis 21 of the oil-gas separator. This design ensures that the nozzle drives the drive wheel to rotate counterclockwise.

[0033] like Figure 3 As shown, the inner diameter of the nozzle 3 increases from its outlet end to its inlet end, and three steps are provided in the nozzle, namely a first step 31, a second step 32 and a third step 33, and the inner sidewalls of the nozzle 3 are connected between each step. In the present application, the inner sidewalls between each step are arranged parallel to each other.

[0034] Optionally, the inner sidewalls between the steps may be arranged horizontally, that is, the inner diameters of the nozzles 3 between two adjacent steps are equal.

[0035] Optionally, the number of steps provided in the nozzle 3 ranges from 1 to 4. The number of steps provided in the nozzle 3 can be adjusted according to the driving oil pressure. The higher the driving oil pressure, the more steps there are; conversely, the lower the driving oil pressure, the fewer steps there are. Currently, four steps are sufficient to achieve pressure reduction and speed reduction in oil-gas separators available on the market.

[0036] The inner diameter of the outlet end of the nozzle 3 is 2 mm, and the inner diameter of the inlet end of the nozzle 3 is 4 mm.

[0037] Optionally, the inner diameter of the outlet end of the nozzle 3, i.e., the side of the third step 33 facing away from the second step 32, can be set to 1.6 mm to 3 mm. The inner diameter of the outlet end of the nozzle 3 is adjusted according to the driving oil pressure. The higher the driving oil pressure, the smaller the inner diameter of the outlet end of the nozzle 3; conversely, the lower the driving oil pressure, the larger the inner diameter of the outlet end of the nozzle 3.

[0038] Preferably, the inner diameter of the nozzle 3's outlet is between 2 mm and 2.5 mm. This range of 2 mm to 2.5 mm prevents the nozzle 3's outlet from being clogged by impurities in the drive oil, maintains a moderate amount of drive oil, and maximizes drive efficiency. However, if the inner diameter of the nozzle 3's outlet is greater than 2.5 mm, the increase in the oil-gas separation device 2's rotational speed decreases as the inner diameter increases, resulting in lower drive efficiency.

[0039] Optionally, the inner diameter of the inlet end of the nozzle, that is, the side of the first step 31 away from the second step 32 , can be set to 3 mm to 5 mm.

[0040] The second embodiment discloses an oil-gas separator using the oil-gas separator driving device, comprising:

[0041] A housing 4, wherein a bearing seat is provided in the housing 4, and a bearing is provided in the bearing seat;

[0042] An oil-gas separation device 2, wherein the oil-gas separation device 2 is disposed in the housing 4, and a central axis 21 of the oil-gas separation device 2 is passed through the bearing;

[0043] The driving wheel 1 is installed on the central axis 21 of the oil-gas separation device 2;

[0044] The inlet end of the nozzle 3 is communicated with the lubricating oil tank of the automobile engine.

[0045] Among them, Figure 4 As shown, the housing 4 is provided with an inlet, a first outlet 43, and a second outlet 42. The inlet is connected to a first conduit 41, which is used to connect to the vehicle engine to direct the gas-oil mixture generated by the engine to the gas-oil separator. The second outlet 42 allows the separated liquid to flow out. After the gas-oil mixture is separated by the gas-oil separator, liquid lubricating oil is obtained. The liquid lubricating oil is discharged from the second outlet 42 and can be transferred to the engine oil sump for recycling. The first outlet 43 allows the separated gas to flow out.

[0046] Through the above-described technical solution, nozzle 3 sprays liquid onto drive wheel 1, causing it to rotate. Since the inner diameter of nozzle 3 increases from its outlet to its inlet, and since a first step 31, a second step 32, and a third step 33 are provided within the nozzle, lubricating oil collides with the first step 31, the second step 32, and the third step 33 in sequence as it passes through the inner sidewall of nozzle 3, causing localized energy loss in the driving oil, reducing its pressure and the kinetic energy of the impact on drive wheel 1. This reduces the rotational speed of oil-gas separator 2 driven by drive wheel 1, thereby increasing the service life of the oil-gas separator.

[0047] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
