Description

Technical Field

[0001] The utility model relates to the field of lubricating oil, in particular to a lubricating oil blending pretreatment device. Background Art

[0002] Lubricating oil is a lubricant added between the contact surfaces of two relatively moving parts to achieve the purpose of reducing friction, reducing wear and extending the service life of mechanical equipment. Lubricating oil is composed of base oil and additives, of which base oil accounts for 70% or even higher and is the main body of lubricating oil. Base oil often contains a certain amount of impurities, so pretreatment is required before lubricating oil blending, that is, filtering the base oil. However, current lubricating oil filtering devices basically filter the lubricating oil in the oil storage tank at one go, and the filtering effect is not good.

[0003] To this end, announcement number CN209475762U announced a lubricating oil base oil impurity filtering device, which uses centrifugal force to throw the lubricating oil out of the filter hole, while the impurities are retained inside the filter hole, thereby separating the lubricating oil from the impurities. The rotation of the filter can increase the filtration speed of the lubricating oil. The impurity adsorption plate arranged at the bottom of the device can perform secondary filtration on the lubricating oil at the bottom of the filter tank, and the filtration effect is good.

[0004] Although the device in the above document has a good filtering effect on the base oil, impurities are easily dropped out of the opening at the bottom of the filter, thus affecting the filtering effect, and the impurity adsorption plate needs to be driven by a motor to rotate, which is more costly. Secondly, the impurity adsorption plate is designed horizontally. Due to the centrifugal force, the base oil is generally located on both sides, which will cause the impurities adsorbed by the impurity adsorption plates on both sides to be too much, affecting the filtering effect, while the impurity adsorption plate in the middle has a lower utilization rate. For this reason, the utility model provides a lubricating oil blending pretreatment device. Utility Model Content

[0005] The main purpose of the utility model is to provide a lubricating oil blending pretreatment device, in which a motor located on the top of the filter tank can drive the filter and the impurity adsorption plate to rotate, which can greatly save costs, and the impurity adsorption plate can rotate around the connecting rod, so that each impurity adsorption plate can effectively contact the impurities, and the bottom of the filter is designed to be sealed to avoid the leakage of impurities, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A lubricating oil blending pretreatment device comprises a filter tank, wherein a rotating rod driven by a motor at the top of the filter tank is installed inside the filter tank, a filter with filter holes and an upper opening formed on the top side wall is welded to the bottom end of the rotating rod, and the bottom end of the rotating rod is fixedly connected to the bottom surface of the filter, a connecting rod welded to an impurity adsorption plate on the outer wall is welded to the bottom end of the filter, an oil drain pipe equipped with a valve is interconnected to the lower part of the outer wall of the filter tank, and a refueling pipe is interconnected to the right part of the top end of the filter tank.

[0008] Furthermore, the bottom end of the filter tank is in a slope shape inclined toward the oil drain pipe.

[0009] Furthermore, a bearing for rotating the shaft is embedded and fixed at the top of the filter tank.

[0010] Furthermore, the rear portion of the top of the filter tank is fixedly connected to an L-shaped rod that fixes the head and the motor, the transmission shaft of the motor is fixedly connected to the top of the rotating shaft, and the bottom end of the rotating shaft is fixedly connected to the top of the rotating rod.

[0011] Furthermore, a base is welded to the bottom end of the filter tank.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the difference between the filter and the comparative document is that the bottom is closed, and the rotation of the rotating shaft is driven by the motor, and the rotating shaft rotates along the inside of the bearing, and the rotating shaft drives the rotation of the rotating rod, and the rotating rod drives the rotation of the filter. In this way, when the base oil enters the filter through the filling pipe, the base oil will be thrown out from the through hole on the filter due to the rotation of the filter, and the impurities will remain in the filter, and the filter will also drive the rotation of the connecting rod to drive the impurity adsorption plate to rotate around the connecting rod. In this design, each impurity adsorption plate can effectively contact the impurities, and a motor located at the top of the filter tank can drive the rotation of the filter and the impurity adsorption plate, which can save costs greatly. Finally, the filtered base oil is discharged from the oil drain pipe. In this way, the base oil is first filtered to pre-treat the lubricating oil blending. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-3 A lubricating oil blending pretreatment device is described, comprising a filter tank 1, wherein a rotating rod 2 driven by a motor 3 at the top of the filter tank 1 is installed inside, a filter 4 with a filter hole and an upper opening on the top side wall is welded to the bottom end of the rotating rod 2, and the bottom end of the rotating rod 2 is fixedly connected to the bottom surface of the filter 4, a connecting rod 5 welded to an impurity adsorption plate 6 on the outer wall is welded to the bottom end of the filter 4, an oil drain pipe 7 equipped with a valve is interconnected on the lower part of the outer wall of the filter tank 1, and a refueling pipe 10 is interconnected on the right part of the top end of the filter tank 1.

[0019] The bottom end of the filter tank 1 is in a slope shape inclined toward the oil drain pipe 7, which is more conducive to the discharge of the filtered base oil.

[0020] Among them, a bearing 8 for rotating the rotating shaft 9 is embedded and fixed at the top of the filter tank 1, and an L-shaped rod 12 for fixing the head and the motor 3 is fixedly connected at the rear part of the top of the filter tank 1. The transmission shaft of the motor 3 is fixedly connected to the top of the rotating shaft 9, and the bottom end of the rotating shaft 9 is fixedly connected to the top of the rotating rod 2.

[0021] It can be understood that the motor 3 drives the rotating shaft 9 to rotate, the rotating shaft 9 rotates along the inside of the bearing 8, the rotating shaft 9 drives the rotating rod 2 to rotate, and the rotating rod 2 drives the filter 4 to rotate.

[0022] A base 11 is welded to the bottom of the filter tank 1 . The base 11 has a certain height and can raise the filter tank 1 and the oil drain pipe 7 to a certain height.

[0023] It should be noted that the utility model relates to a lubricating oil blending pretreatment device. The difference between the filter 4 of the utility model and that in the comparative document is that the bottom is closed, and the rotation of the rotating shaft 9 is driven by the motor 3. The rotating shaft 9 rotates along the inside of the bearing 8, and the rotating shaft 9 drives the rotation of the rotating rod 2. The rotating rod 2 drives the rotation of the filter 4. In this way, when the base oil enters the filter 4 through the filling pipe 10, the base oil will be thrown out from the through hole on the filter due to the rotation of the filter 4, and the impurities will remain in the filter 4. The filter 4 will also drive the rotation of the connecting rod 5 to drive the impurity adsorption plate 6 to rotate around the connecting rod 5. In this way, each impurity adsorption plate 6 can effectively contact the impurities, and a motor 3 located at the top of the filter tank 1, that is, It can drive the filter 4 and the impurity adsorption plate 6 to rotate, which can save costs well. Finally, the filtered base oil is discharged from the oil drain pipe 7 (open its valve). In this way, the base oil is first filtered to pre-treat the lubricating oil blending. The bottom end of the filter tank 1 is a slope inclined toward the oil drain pipe 7, which is more conducive to the discharge of the filtered base oil. The base 11 has a certain height, and the filter tank 1 and the oil drain pipe 7 can be raised to a certain height, so that the oil barrel can be placed under the oil drain pipe 7 to collect the base oil. The top part of the filter tank 1 of the utility model is a top cover (as shown in the figure), which is detachably connected to the tank body of the filter tank 1 by bolts, wherein the filter components are all installed on the top cover, and the top cover can be removed for cleaning.
