Technical Field

[0001] The utility model relates to the field of lubricating oil mixing devices, and particularly relates to a mixing device for lubricating oil production. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts, mainly playing roles such as lubrication, cooling, rust prevention, cleaning, sealing, and buffering. During the production process of lubricating oil, various additives need to be mixed into the lubricating oil. During the mixing process, workers generally measure an appropriate amount of additives with a measuring cylinder and pour them into the mixing tank for mixing. The speed of adding additives is relatively slow, reducing the production efficiency. For this reason, a mixing device for lubricating oil production is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.

[0019] As shown Figure 1 Figure 2 shown, a mixing device for lubricating oil production includes a mixing tank body 3. A sealing end cover 2 is provided at the upper end of the mixing tank body 3. A liquid inlet 7 is provided on the sealing end cover 2 at the upper end of the mixing tank body 3. A liquid discharge port 4 is provided at the lower end of the mixing tank body 3. A stirring motor 1 is fixedly installed at the middle position of the sealing end cover 2 at the upper end of the mixing tank body 3. A pipeline structure 5 is connected to the sealing end cover 2. An adding mechanism 6 is connected to the docking port 501. The lubricating oil is poured into the mixing tank body 3 through the liquid inlet 7. After the lubricating oil is poured into the mixing tank body 3, the stirring rod can be rotated by the stirring motor 1 to stir the lubricating oil. During the stirring process, a quantitative additive can be added into the mixing tank body 3 through the cooperation of the pipeline structure 5 and the adding mechanism 6, thus replacing manual operation to quickly add the additive into the mixing tank body 3 and improving the production efficiency.

[0020] As shown Figure 3 shown, the pipeline structure 5 includes a tee joint 502 fixed on the sealing end cover 2. A docking port 501, a first one-way valve 503 and a second one-way valve 504 are respectively connected to the three ports of the tee joint 502. A conveying pipeline 505 is connected to the tee joint 502 at the position of the second one-way valve 504. The first one-way valve 503 on the port of the tee joint 502 extends into the mixing tank body 3. A connection hole is opened on the sealing end cover 2. The tee joint 502 is connected to the sealing end cover 2 through the connection hole. The hydraulic cylinder 604 is communicated with the mixing tank body 3 and the conveying pipeline 505 respectively through the tee joint 502. The second one-way valve 504 only allows the liquid in the conveying pipeline 505 to enter the hydraulic cylinder 604 through the tee joint 502. The first one-way valve 503 only allows the liquid in the hydraulic cylinder 604 to be discharged through the tee joint 502.

[0021] Specifically, the additive can be conveyed into the tee joint 502 through the conveying pipeline 505. When the hydraulic cylinder 604 sucks liquid, the first one-way valve 503 will prevent the liquid from entering the mixing tank body 3. When the liquid is squeezed into the hydraulic cylinder 604, the second one-way valve 504 can prevent the liquid from flowing back into the conveying pipeline 505.

[0022] As shown Figure 4As shown in the figure, the adding mechanism 6 includes a hydraulic cylinder 604 fixed on the docking port 501. One end of the hydraulic cylinder 604 is equipped with a sealing end cap 602. A servo electric push rod 601 is fixedly installed at the middle position of the sealing end cap 602. A piston 603 is fixedly installed at the output end of the servo electric push rod 601 inside the hydraulic cylinder 604. An air vent hole 606 is provided at the edge position of the sealing end cap 602. The sealing end cap 602 has internal threads and is installed at one end of the hydraulic cylinder 604 through the threads. An inlet and outlet notch 605 is provided at the middle position of the sealing end cap 602. The servo electric push rod 601 extends into the hydraulic cylinder 604 through the inlet and outlet notch 605. The servo electric push rod 601 is installed at one end of the hydraulic cylinder 604 through the sealing end cap 602. The piston 603 is movably installed inside the hydraulic cylinder 604 through the servo electric push rod 601.

[0023] Specifically, the conveying pipeline 505 is immersed in the additive. The servo electric push rod 601 can drive the piston 603 to reciprocate inside the hydraulic cylinder 604. When the piston 603 moves towards the outside of the hydraulic cylinder 604, the additive will be sucked into the hydraulic cylinder 604. When the piston 603 moves towards the inside of the hydraulic cylinder 604, the additive inside the hydraulic cylinder 604 will be pressed into the mixing tank body 3. And the rotating sealing end cap 602 can be detached from the hydraulic cylinder 604.

[0024] It should be noted that the present utility model is a mixing device for lubricating oil production. During actual use, first, lubricating oil is poured into the mixing tank body 3 through the liquid inlet 7. After the lubricating oil is poured into the mixing tank body 3, the stirring motor 1 can drive the stirring rod to rotate, thereby stirring the lubricating oil. During the stirring process of the lubricating oil, the servo electric push rod 601 can be controlled to reciprocate, so as to drive the piston 603 to reciprocate inside the hydraulic cylinder 604, thereby adding the additive into the mixing tank body 3. By controlling the stroke of the servo electric push rod 601, the addition amount of the additive can be accurately controlled, thus replacing manual operation to quickly add a fixed amount of additive into the mixing tank body 3, improving production efficiency. And after unscrewing the sealing end cap 602, the piston 603 can be taken out, which is convenient for cleaning the inside of the hydraulic cylinder 604.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
