Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, and in particular to a mixing equipment for producing lubricating oil. Background Technology

[0002] Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil and determines its basic properties. Additives can compensate for and improve the shortcomings of base oil performance and give it certain new properties. They are an important part of lubricating oil. Therefore, in the production of lubricating oil, the required additives are added to the base oil in a mixing device and mixed to obtain the desired finished product.

[0003] Specifically, a concentration ratio adjustment device for ink processing, patent number CN221386322U, when used to produce lubricating oil, cannot perform preliminary mixing during the introduction of base oil and additives. At the same time, due to the influence of the introduction sequence, the base oil and additives are prone to stratification, resulting in a large amount of additives being distributed on the liquid surface. Even if the base oil and additives are mixed thoroughly by stirring later, it will affect the processing quality. Summary of the Invention

[0004] The purpose of this invention is to provide a mixing device for producing lubricating oil.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A mixing device for producing lubricating oil includes a barrel body, wherein a rotating shaft connected to a motor I at the top of the barrel body is disposed within the barrel body, and an agitator is disposed on the rotating shaft.

[0007] Multiple sets of circulation mechanisms are provided on the outside of the barrel body. A mixing barrel for the shaft to pass through is also provided at the top of the barrel body. A mixing rod is provided on the shaft inside the mixing barrel. A discharge pipe is provided at the bottom of the mixing barrel. Multiple sets of transparent cylinders connected to the mixing barrel through connecting pipes are also provided at the top of the barrel body. Scale values ​​are applied on the side wall of the cylinder. A conical boss driven by a hydraulic rod is provided inside the cylinder. The cylinder side walls on the upper and lower sides of the boss are connected by a coil pipe with valves installed. An inlet pipe is also provided on the cylinder below the boss.

[0008] The circulation mechanism includes a vertical circulation pipe located on the outside of the barrel. Both ends of the circulation pipe are connected to the barrel through mounting pipes. A pressure plate is installed inside the circulation pipe above the mounting pipe, and a lead screw driven by motor II is installed on the pressure plate.

[0009] Preferably, the size of the boss is adapted to the size of the internal opening of the cylinder, the cylinder is made of transparent resin, and the hydraulic rod is located at the top of the cylinder.

[0010] Preferably, both the unloading pipe and the connecting pipe are equipped with solenoid valves.

[0011] Preferably, a discharge pipe is provided at the bottom of the side wall of the barrel, and a manhole is also provided on the side wall of the barrel.

[0012] Preferably, a solenoid valve is installed on the upper mounting pipe, and a check valve is installed on the lower mounting pipe.

[0013] Preferably, the circulation pipe is sealed at both ends, the internal opening of the circulation pipe has a rectangular cross-section, the size of the pressure plate is adapted to the size of the internal opening of the circulation pipe, and the pressure plate is also provided with a screw hole for screwing with the lead screw.

[0014] The beneficial effects of this invention are as follows: This invention improves the mixing efficiency and effect between base oil and additives by introducing the mixture into the container after initial mixing. At the same time, the circulation mechanism guides the liquid from the top of the container to the bottom, preventing the additives from being located on the liquid surface and not easily coming into contact with the base oil at the bottom of the container, thus making the mixing of base oil and additives more thorough.

[0019] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] A mixing device for producing lubricating oil includes a barrel body 1, inside which a rotating shaft 3 connected to a motor 12 at its top is disposed, and a stirring paddle 4 is disposed on the rotating shaft 3.

[0021] Multiple sets of circulation mechanisms 5 are provided on the outside of the barrel body 1. A mixing barrel 15 for the rotating shaft 3 to pass through is also provided at the top inside the barrel body 1. A mixing rod 16 is provided on the rotating shaft 3 inside the mixing barrel 15. A discharge pipe 6 is provided at the bottom of the mixing barrel 15.

[0022] The top of the barrel 1 is also provided with a number of transparent cylinders 7 connected to the mixing barrel 15 via connecting pipes 8. The cylinders 7 have scale values ​​on their side walls. Inside the cylinders 7, there is a conical boss 9 driven by a hydraulic rod 10. The cylinders 7 on the upper and lower sides of the boss 9 are connected by a coil pipe 11 with a valve installed. The cylinder 7 below the boss 9 is also provided with a liquid inlet pipe 12.

[0023] The circulation mechanism 5 includes a vertical circulation pipe 51 located outside the barrel 1. The circulation pipe 51 is sealed at both ends. The internal opening of the circulation pipe 51 has a rectangular cross-section. Both ends of the circulation pipe 51 are connected to the barrel 1 through mounting pipes 52. A solenoid valve is installed on the upper mounting pipe 52, and a check valve is installed on the lower mounting pipe 52. A pressure plate 53 is installed inside the circulation pipe 51 above the mounting pipe 52. The size of the pressure plate 53 is adapted to the size of the internal opening of the circulation pipe 51. A lead screw 55 driven by a motor II 54 is installed on the pressure plate 53. The pressure plate 53 also has a screw hole for screwing the lead screw 55.

[0024] In this embodiment, the size of the protrusion 9 is adapted to the size of the internal opening of the cylinder 7. The cylinder 7 is made of transparent resin, and the hydraulic rod 10 is located on the top of the cylinder 7.

[0025] In this embodiment, both the unloading pipe 6 and the connecting pipe 8 are equipped with solenoid valves.

[0026] like Figure 1 , 2 As shown, a discharge pipe 13 is provided at the bottom of the side wall of the barrel 1, and a manhole 14 is also provided on the side wall of the barrel 1.

[0027] The method of using this invention is as follows: A specified amount of base oil and additives are injected into the cylinder 7 below the corresponding protrusion 9 through the liquid inlet pipe 12. Since the amount of base oil used is large, the volume of the cylinder 7 used to hold the base oil also needs to be increased accordingly during the design. The amount of liquid held inside the cylinder is known by the scale value on the cylinder 7.

[0028] When adding base oil and additives into the barrel 1, the solenoid valve on the connecting pipe 8 is opened to adjust its opening, so that the base oil or additives in the cylinder 7 are introduced into the mixing barrel 15 through the connecting pipe 8 at a certain flow rate. At this time, the motor I2 drives the mixing rod 16 and the stirring paddle 4 to rotate through the rotating shaft 3. The mixing rod 16 can initially stir and mix the liquid introduced into the mixing barrel 15. During this process, the solenoid valve on the discharge pipe 6 is in the closed state. When the liquid level in the mixing barrel 15 is high (a liquid level sensor can be installed in the mixing barrel 15 for detection), the discharge pipe 6 is opened to guide the liquid in the mixing barrel 15 into the bottom of the barrel 1. At this time, the discharge flow rate of the discharge pipe 6 is equal to the flow rate introduced by the multiple sets of connecting pipes 8, so as to ensure that there is a lot of liquid temporarily stored in the mixing barrel 15 and it is initially stirred and mixed by the rotating mixing rod 16.

[0029] When the liquid is introduced into the bottom of the tank 1, the rotating agitator 4 can stir and mix it to further improve the mixing efficiency and effect of the liquid. After the liquid in the cylinder 7 is drained, the hydraulic rod 10 can drive the protrusion 9 to move down to scrape and clean the inner wall of the cylinder 7, preventing liquid from adhering to the inner wall and causing confusion when adding fresh liquid later. The moving protrusion 9 can clean the cylinder 7. When the protrusion 9 moves down, a small amount of liquid may be on its top. When it moves up and resets, its top edge is flush with the top of the coil pipe 11. After the coil pipe 11 is opened, the liquid on the top of the protrusion 9 flows along its slope to the coil pipe 11, then flows to the cylinder 7 below the protrusion 9, and finally flows into the tank 1.

[0030] When the liquid inside the tank 1 is agitated and mixed by the rotating agitator 4, the liquid level overflows the uppermost mounting pipe 52. At this time, the solenoid valve on the upper mounting pipe 52 is opened, allowing the liquid at the top of the tank 1 to flow into the circulation pipe 51 below the pressure plate 53. When the circulation pipe 51 is full of liquid, the upper mounting pipe 52 is closed. At this time, the motor II 54 drives the lead screw 55 to rotate in the screw hole on the pressure plate 53, thereby driving the pressure plate 53 to move down in the circulation pipe 51 and squeezing the liquid in the circulation pipe 51 to flow into the bottom of the tank 1 through the lower mounting pipe 52. At this time, the check valve on the lower mounting pipe 52 can prevent the liquid in the tank 1 from flowing back. When the pressure plate 53 moves to the bottom of the circulation pipe 51, it can move upward and reset. Then, the above steps are repeated to achieve the circulation of liquid on both sides of the tank 1, so as to facilitate the agitator 4 to mix it thoroughly. This prevents the previous situation where a large amount of additives were located on the surface of the liquid due to the order of addition, which prevented them from making good contact with the base oil at the bottom of the tank 1 and thus affecting the purpose of mixing.

[0031] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
