Description

Technical Field

[0001] This utility model belongs to the technical field of lubricating oil blending equipment, and relates to a lubricating oil stirring device. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant widely used in various automobiles and mechanical equipment. Its core function is to reduce friction and wear between relatively moving parts. This substance is formulated from base oil and various functional additives, possessing five core functions: lubrication and friction reduction, auxiliary heat dissipation, rust and corrosion prevention, cleaning and dispersion, and sealing and buffering. Its application essentially involves intervening at the contact interface of moving parts, reducing frictional resistance and suppressing mechanical wear by forming a lubricating film, thereby effectively extending the service life of the equipment.

[0003] The existing patent document with authorization publication number CN220214764U discloses an easy-to-stir lubricate mixing vessel, which includes a mixing vessel body, a pulse air inlet pipe, a feed pipe, a stirring drive motor, a stirring auxiliary mechanism, and a cleaning and splash-proof mechanism; the pulse air inlet pipe is fixedly connected to the bottom of the mixing vessel body; the feed pipe is fixedly connected to the top of the mixing vessel body; the stirring drive motor is fixedly connected to the top of the mixing vessel body; the stirring auxiliary mechanism is disposed inside the mixing vessel body; and the cleaning and splash-proof mechanism is disposed in the middle position inside the mixing vessel body.

[0004] However, the aforementioned existing technologies still have the following problems:

[0005] The pulse air inlet pipe of the above-mentioned prior art is set at the bottom of the mixing tank. The airflow impacts from bottom to top, so the energy of the airflow is exhausted when it impacts the middle or near the liquid surface. This results in poor stirring effect in the upper part of the material in the mixing tank, and it takes longer for the whole tank to achieve a qualified mixing effect, which is not conducive to the rapid and efficient operation of the mixing process. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lubricating oil stirring device to solve the problems mentioned in the background art. This utility model can make multiple air outlets located in various places inside the mixing vessel, and at the same time, it can be used in conjunction with a mechanical stirring structure to stir the lubricating oil in the mixing vessel, thereby improving the overall stirring effect of the materials in the mixing vessel, greatly reducing the time required for the whole tank to reach the qualified mixing effect, which is conducive to the rapid and efficient operation of the mixing process.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0008] A lubricating oil stirring device, comprising a mixing tank, characterized in that:

[0009] The top of the mixing tank is equipped with a protective cover, and an air inlet pipe is connected through the top of the protective cover. The inner wall of the air inlet pipe is connected to a connecting pipe through a sealed bearing. The connecting pipe passes through the top wall of the mixing tank and forms a sealed rotational fit with it.

[0010] The connecting pipe is provided with multiple radially extending stirring rods at one end inside the mixing tank, and the connecting pipe is connected to multiple first vent pipes equipped with first one-way valves at one end inside the mixing tank.

[0011] A motor is fixed inside the protective cover. The output shaft of the motor is connected to a first bevel gear. A second bevel gear that meshes with the first bevel gear is sleeved on the connecting pipe.

[0012] The mixing tank is equipped with an exhaust pipe located on one side of the protective cover at the top, and an exhaust valve is installed on the exhaust pipe.

[0013] Furthermore, at least one connecting rod is fixed to the outer wall of the connecting pipe, and a scraper is fixed to the end of the connecting rod. The arc-shaped outer edge of the scraper is in close contact with the inner wall of the mixing tank to scrape off the residue on the inner wall of the mixing tank.

[0014] Furthermore, a vertically arranged rotating shaft is fixed at the center of the bottom wall of the mixing tank, and a shaft hole matching the rotating shaft is opened at the bottom of the connecting pipe. An annular groove is opened on the inner wall of the shaft hole, and a rolling bearing is embedded in the annular groove. The rotating shaft passes through the shaft hole and is fixed to the inner wall of the inner ring of the rolling bearing, so that the connecting pipe can rotate stably around the rotating shaft.

[0015] Furthermore, the mixing tank is provided with a feed inlet and a discharge outlet, both of which are equipped with control valves, and the bottom of the mixing tank is fixed with four support legs arranged in a rectangular pattern.

[0016] Furthermore, the outer wall of the connecting pipe is equidistantly distributed with multiple stirring branch pipes located inside the mixing tank along the axial direction, and the multiple stirring branch pipes are staggered in the circumferential direction; each stirring branch pipe is provided with multiple second vent pipes, and the second vent pipe is provided with a second one-way valve.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model, by setting up a connecting pipe and multiple first gas outlet pipes in cooperation, allows gas to be sent directly to all parts of the liquid after exiting from the outlet of the first gas outlet pipe, without having to travel a long path. This achieves effective control of energy attenuation, which is beneficial to ensuring the stirring and blending effect of the liquid in the blending tank and shortening the blending operation time of the whole tank. At the same time, this utility model uses a drive motor to drive the connecting pipe to rotate, and the connecting pipe drives multiple stirring rods to rotate, which can combine mechanical stirring and pulse blending stirring, which can greatly improve the blending effect and the blending quality.

[0019] 2. This utility model features multiple circumferentially staggered stirring branch pipes and multiple second air outlet pipes. Gas is injected into the connecting pipe through the air inlet pipe. The gas enters the stirring branch pipes and is released in layers and directions through the second air outlet pipes (with second one-way valves) on their surfaces, enhancing the uniformity of gas dispersion. The connecting pipe is rotated by a drive motor. As the stirring branch pipes rotate with the connecting pipe, the circumferentially staggered distribution enhances the liquid turbulence effect, ensuring the mixing and blending effect of liquids in all parts of the mixing tank and shortening the overall mixing time. At the same time, the rotation of the stirring branch pipes with the connecting pipe achieves mechanical mixing and blending of the lubricating oil, further improving the quality and efficiency of lubricating oil blending.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] like Figure 1-3 As shown, a lubricating oil stirring device includes a mixing tank 1, characterized in that:

[0031] The top of the mixing tank 1 is provided with a protective cover 2. An air inlet pipe 3 is connected through the top of the protective cover 2. The inner wall of the air inlet pipe 3 is connected to a connecting pipe 24 through a sealed bearing 4. The connecting pipe 24 passes through the top wall of the mixing tank 1 and forms a sealed rotational fit with it.

[0032] The connecting pipe 24 is provided with multiple radially extending stirring rods 5 at one end inside the mixing tank 1. The connecting pipe 24 is connected to multiple first gas outlet pipes 7 equipped with first one-way valves 6 at one end inside the mixing tank 1, which are used to inject gas into the mixing tank 1.

[0033] A motor 8 is fixed inside the protective cover 2. The output shaft of the motor 8 is connected to a first bevel gear 9. A second bevel gear 10 that meshes with the first bevel gear 9 is sleeved on the connecting pipe 24, driving the connecting pipe 24 to rotate around its own axis.

[0034] The mixing tank 1 is equipped with an exhaust pipe 11 located on one side of the protective cover 2. An exhaust valve 25 is installed on the exhaust pipe 11. The gas pressure inside the tank is controlled by adjusting the gas flow rate of the air inlet pipe 3; if necessary, the exhaust valve 25 of the exhaust pipe 11 is opened to balance the pressure inside the tank.

[0035] At least one connecting rod 12 is fixed to the outer wall of the connecting pipe 24. A scraper 13 is fixed to the end of the connecting rod 12. The arc-shaped outer edge of the scraper 13 is in close contact with the inner wall of the mixing tank 1 to scrape off residues on the inner wall of the mixing tank 1. The scraper 13 rotates with the connecting pipe 24, continuously scraping the inner wall of the mixing tank 1, reducing the amount of lubricating oil adhering to the inner wall of the mixing tank 1, and ensuring the processing quality of the lubricating oil.

[0036] like Figure 1-3 As shown, a vertically arranged rotating shaft 14 is fixed at the center of the bottom wall of the mixing tank 1. The bottom of the connecting pipe 24 has a shaft hole 15 that matches the rotating shaft 14. An annular groove is formed on the inner wall of the shaft hole 15. A rolling bearing 16 is embedded in the annular groove. The rotating shaft 14 passes through the shaft hole 15 and is fixed to the inner wall of the inner ring of the rolling bearing 16, so that the connecting pipe 24 can rotate stably around the rotating shaft 14. The mixing tank 1 is provided with a feed inlet 17 and a discharge outlet 18. Both the feed inlet 17 and the discharge outlet 18 are provided with control valves 19. The bottom of the mixing tank 1 is fixed with four support legs 20 arranged in a rectangular pattern.

[0037] The specific implementation method of Embodiment 1 of this utility model is as follows:

[0038] Close the discharge port 18 control valve 19 and open the inlet port 17 control valve 19 to inject the lubricating oil raw material into the mixing tank 1 through the inlet port 17;

[0039] Turn on the motor 8 inside the protective cover 2, and drive the connecting pipe 24 to rotate around its own axis through the meshing of the first bevel gear 9 and the second bevel gear 10.

[0040] Gas is supplied to the connecting pipe 24 through the air inlet pipe 3, and the gas is injected into the lubricating oil through the first air outlet pipe 7.

[0041] When the connecting pipe 24 rotates, the outer wall connecting rod 12 drives the scraper 13 to rotate synchronously, continuously scraping the inner wall of the mixing tank 1 to prevent residue from accumulating.

[0042] By setting up a connecting pipe 24 and multiple first gas outlet pipes 7 in coordination, the gas can be sent directly to all parts of the liquid after exiting from the outlet of the first gas outlet pipe 7, without having to go through a long path. This achieves effective control of energy attenuation, which is beneficial to ensuring the stirring and blending effect of the liquid in the blending tank 1 and shortening the blending operation time of the whole tank. By driving the connecting pipe 24 to rotate through the drive motor 8, the connecting pipe 24 drives the multiple stirring rods 5 to rotate, which can combine the mechanical stirring of the transmission and the pulse blending stirring, which can greatly improve the blending effect and the blending quality.

[0043] Example 2

[0044] like Figure 4-6 As shown, the outer wall of the connecting pipe 24 has multiple stirring branch pipes 21 located in the mixing tank 1, which are equidistantly distributed along the axial direction. The multiple stirring branch pipes 21 are staggered in the circumferential direction. The outer wall of the connecting pipe 24 has three stirring branch pipes 21 located in the mixing tank 1, which are equidistantly distributed along the axial direction.

[0045] Each stirring branch pipe 21 is equipped with multiple second vent pipes 22, and each second vent pipe 22 is equipped with a second one-way valve 23.

[0046] The specific implementation method of Embodiment 2 of this utility model is as follows:

[0047] When the motor 8 is turned on, the first bevel gear 9 meshes with the second bevel gear 10, driving the connecting pipe 24 to drive the stirring branch pipe 21 to rotate synchronously.

[0048] Gas is injected into the connecting pipe 24 through the air inlet pipe 3. The gas enters the stirring branch pipe 21 and is released in layers and multiple directions through the second air outlet pipe 22 (with a second one-way valve 23) on its surface, which enhances the uniformity of gas dispersion. When the stirring branch pipe 21 rotates with the connecting pipe 24, the circumferential staggered distribution enhances the liquid turbulence effect, ensuring the stirring and blending effect of liquid in all parts of the blending tank 1 and shortening the blending operation time of the whole tank. At the same time, when the stirring branch pipe 21 rotates with the connecting pipe 24, it realizes the mechanical stirring and blending of lubricating oil, further improving the blending quality and efficiency of lubricating oil.

[0049] Embodiment 2 of this utility model can combine mechanical stirring and pulse mixing, which can greatly improve the mixing effect and the mixing quality.

[0050] This utility model embodiment integrates mechanical stirring and gas injection pulse blending functions, improving production efficiency and the uniformity of lubricant mixing; dynamic scraping reduces raw material waste and is suitable for high viscosity lubricant production scenarios.

[0051] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
