Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, and in particular to a high-efficiency mixing and stirring device for lubricating oil production. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and machinery to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties. Additives compensate for and improve the shortcomings of the base oil, imparting certain new properties, and are an important component of lubricating oil. Therefore, mixing and stirring are necessary during the production process.

[0003] Existing mixing devices typically use a one-way mixing arm to mix lubricating oil raw materials. When the one-way mixing arm mixes the raw materials, a centrifugal effect occurs. After the raw materials are drawn into the centrifugal center, the mixing effect with other raw materials is reduced, which affects the production quality of lubricating oil and requires more time to mix, thus reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency mixing and stirring device for lubricating oil production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency mixing and stirring device for lubricating oil production includes a support frame. Three support legs are fixedly connected to the lower surface of the support frame, and a mixing cylinder is fixedly connected to the upper surface of the support frame. A cylinder cover is fixedly connected to the top of the mixing cylinder by four positioning bolts. A stirring assembly is fixedly connected to the upper surface of the cylinder cover. The stirring assembly includes a first motor, a connecting shaft is fixedly connected to the output end of the first motor, a strip plate is fixedly connected to the bottom end of the connecting shaft, two vertical rods are fixedly connected to the lower surface of the strip plate, and several first stirring arms are fixedly connected to the surfaces of the two vertical rods. A second motor is fixedly connected to the bottom end of the mixing cylinder, a circular shaft is fixedly connected to the output end of the second motor, and several second stirring arms are fixedly connected to the surface of the circular shaft.

[0007] Preferably, the length of the strip plate is less than the inner diameter of the mixing cylinder, and the positions of the first stirring arm and the second stirring arm are mutually crisscrossed.

[0008] Preferably, the lower surface of the strip plate is provided with a circular rotating groove, the position of the circular rotating groove corresponds to the position of the circular shaft, and the circular shaft is adapted to the circular rotating groove.

[0009] Preferably, the bottom wall of the mixing cylinder is fixedly connected to an inclined guide frame, the upper surface of the inclined guide frame is provided with a discharge hole, the inner wall of the discharge hole is fixedly connected to a discharge pipe, and the bottom end of the discharge pipe extends to the bottom end of the mixing cylinder and is fixedly connected to a sealing cap.

[0010] Preferably, the bottom end of the mixing cylinder is provided with a through hole that is compatible with the discharge pipe, and the position of the second motor does not correspond to the position of the discharge pipe.

[0011] Preferably, a transmission plate is fixedly connected to the surface of the circular shaft, and an inclined scraper is fixedly connected to the surface of the transmission plate. The inclined scraper is slidably connected to the inclined surface of the inclined guide frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] By configuring the stirring components, two sets of motors drive two sets of stirring arms to rotate in opposite directions during use. This prevents centrifugal effects from occurring within the mixing drum during the stirring process, ensuring that the raw materials are not drawn into the centrifugal center and thus reducing the uniformity of the mixture. The two sets of stirring arms can completely agitate the raw materials, resulting in a more uniform mixture. This improves the production quality and efficiency of the lubricating oil. In addition, the transmission plate and the inclined scraper work in conjunction with the inclined guide frame to scrape off the raw materials adhering to the bottom, ensuring that no raw materials remain and avoiding affecting subsequent mixing operations. This also reduces the difficulty of cleaning. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example:

[0020] Reference Figure 1-3 A high-efficiency mixing and stirring device for lubricating oil production includes a support frame 1, three support legs 2 fixedly connected to the lower surface of the support frame 1, a mixing cylinder 3 fixedly connected to the upper surface of the support frame 1, a cylinder cover 5 fixedly connected to the top of the mixing cylinder 3 by four positioning bolts 4, a stirring assembly fixedly connected to the upper surface of the cylinder cover 5, the stirring assembly including a first motor 6, a connecting shaft 7 fixedly connected to the output end of the first motor 6, a strip plate 8 fixedly connected to the bottom end of the connecting shaft 7, two vertical rods 9 fixedly connected to the lower surface of the strip plate 8, a plurality of first stirring arms 10 fixedly connected to the surface of the two vertical rods 9, a second motor 11 fixedly connected to the bottom end of the mixing cylinder 3, a circular shaft 12 fixedly connected to the output end of the second motor 11, and a plurality of second stirring arms 13 fixedly connected to the surface of the circular shaft 12.

[0021] The length of the strip plate 8 is less than the inner diameter of the mixing cylinder 3, and the positions of the first stirring arm 10 and the second stirring arm 13 are intersecting and corresponding to each other. A circular rotating groove is provided on the lower surface of the strip plate 8. The position of the circular rotating groove corresponds to the position of the circular shaft 12, and the circular shaft 12 is adapted to the circular rotating groove.

[0022] After the raw materials are placed into the mixing drum 3, the drum cover 5 is fixed to the top of the mixing drum 3 using the positioning bolts 4. At this time, the first motor 6 and the second motor 11 are turned on. The first motor 6 can drive the strip plate 8 to rotate clockwise through the connecting shaft 7. Therefore, the vertical rod 9 and the first stirring arm 10 can rotate clockwise. The second motor 11 drives the second stirring arm 13 to rotate counterclockwise through the circular shaft 12. Therefore, the two sets of stirring arms can prevent the raw materials in the mixing drum 3 from being subjected to centrifugal force, which can prevent the raw materials from being drawn into the centrifugal state and reduce the mixing uniformity, thus improving the mixing uniformity of the raw materials. In addition, the circular shaft 12 can be inserted into the circular rotating groove, and the circular shaft 12 and the strip plate 8 can support each other to ensure rotational stability.

[0023] An inclined guide frame 14 is fixedly connected to the inner bottom wall of the mixing cylinder 3. A discharge hole is opened on the upper surface of the inclined guide frame 14. A discharge pipe 15 is fixedly connected to the inner wall of the discharge hole. The bottom end of the discharge pipe 15 extends to the bottom end of the mixing cylinder 3 and is fixedly connected to a sealing cover 16. A through hole adapted to the discharge pipe 15 is opened at the bottom end of the mixing cylinder 3. The position of the second motor 11 does not correspond to the position of the discharge pipe 15. A transmission plate 17 is fixedly connected to the surface of the circular shaft 12. An inclined scraper 18 is fixedly connected to the surface of the transmission plate 17. The inclined scraper 18 is slidably connected to the inclined surface of the inclined guide frame 14.

[0024] During rotation, the circular shaft 12 can drive the inclined scraper 18 to slide on the inclined guide frame 14 via the transmission plate 17, thus scraping off the raw materials attached to the bottom, ensuring that no raw materials remain in the mixing drum 3 during the discharge process, reducing the cleaning difficulty for workers, and avoiding the waste of raw materials.

[0025] Working principle: First, open the cylinder cover 5 and put the raw materials into the mixing cylinder 3. At this time, turn on the first motor 6 and the second motor 11. The first motor 6 can drive the strip plate 8 to rotate clockwise through the connecting shaft 7. The strip plate 8 can drive several first stirring arms 10 to rotate clockwise through the two vertical rods 9. The second motor 11 drives several second stirring arms 13 to rotate counterclockwise through the circular shaft 12. Since the first stirring arms 10 and the second stirring arms 13 are cross-corresponding, there will be no collision during the rotation. The two sets of stirring arms can perform bidirectional stirring of the raw materials, avoiding centrifugal force in the mixing cylinder 3 and improving the uniformity of mixing in the mixing cylinder 3. In addition, during the rotation, the circular shaft 12 can drive the inclined scraper 18 to rotate on the surface of the inclined guide frame 14 through the transmission plate 17, which can scrape off the raw materials attached to the bottom, ensuring that no raw materials remain in the mixing cylinder 3 during the discharge process, thus improving the smoothness of discharge.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
