Description

Technical Field

[0001] This utility model relates to the field of oil mixing, specifically an oil rotary jet mixer. Background Technology

[0002] A rotary jet mixer sprays fluid at high speed through a rotating nozzle while simultaneously agitating it, thus thoroughly mixing different fluid components.

[0003] In existing technologies, the vortex nozzle and the agitator rotate in the same direction, resulting in a relatively low relative speed. Therefore, there is room to further increase the relative speed between the liquid being agitated and the liquid being sprayed. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 In this embodiment of the present invention, an oil rotary spray mixer includes a mixing tank 1. The bottom end of the mixing tank 1 is integrally formed with a downwardly protruding feed pipe 2. A solenoid valve 3 is installed on the feed pipe 2. A stirring mechanism that penetrates into the inner cavity of the mixing tank 1 is rotatably installed on the top of the mixing tank 1. A rotating mechanism connected to the stirring mechanism is installed on one side of the top of the mixing tank 1. A rotary spray mechanism is rotatably installed at the bottom end of the stirring mechanism. A feed pipe 5 is rotatably installed on the top of the stirring mechanism. The horizontal part of the feed pipe 5 is fixedly connected to the top of the mixing tank 1 by a mounting bracket 6.

[0019] In this embodiment: First, a first type of oil raw material is added to the mixing tank 1 through the feeding pipe 18 at the top of the mixing tank 1. After the first type of oil raw material is added, the hydraulic pump connected to the feed pipe 5 is started. The hydraulic pump pumps the second type of oil into the stirring mechanism through the feed pipe 5. Then, the second type of oil enters the swirl spraying mechanism through the stirring mechanism. At the same time, the rotating mechanism is started, which drives the stirring mechanism to rotate. The rotating stirring mechanism stirs the oil in the mixing tank 1. The second type of oil sprayed out through the swirl spraying mechanism generates a reaction force during the spraying process, which drives the swirl spraying mechanism to rotate. At this time, the rotation direction of the swirl spraying mechanism is opposite to the rotation direction of the stirring mechanism. Therefore, the relative velocity between the second type of oil sprayed out from the swirl spraying mechanism and the oil being stirred is large, which generates stronger shear force, more complex flow field and enhanced convection. This can more effectively break the internal structure of the liquid, making it easier for the molecules in the liquid to mix with each other, thereby accelerating the stirring speed.

[0020] Please refer to this carefully. Figure 1 and Figure 2 The stirring mechanism includes a hollow rotating shaft 4 rotatably connected to the center of the top plate of the mixing tank 1. Multiple sets of stirrers 11 are fixedly installed on the outer wall of the hollow rotating shaft 4 and in the inner cavity of the mixing tank 1. The top of the hollow rotating shaft 4 is rotatably connected to the feed pipe 5 through an upper bearing 14, and a sealing ring is installed at the rotatable connection position between the feed pipe 5 and the hollow rotating shaft 4.

[0021] In this embodiment: when the rotating mechanism is running, the rotating mechanism drives the hollow rotating shaft 4 to rotate, the hollow rotating shaft 4 drives the agitator 11 to rotate, and the agitator 11 fully stirs the oil inside the mixing tank 1.

[0022] Please refer to this carefully. Figure 3 and Figure 4 The rotating mechanism includes a rotary motor 10 mounted on one side of the top of the mixing tank 1 via a bracket. The output shaft of the rotary motor 10 passes through the bracket, and a circular hole is provided on the bracket for the output shaft of the rotary motor 10 to pass through. The inner diameter of the circular hole is larger than the diameter of the output shaft of the rotary motor 10. A drive disc 9 is coaxially fixedly connected to the bottom end of the output shaft of the rotary motor 10. The drive disc 9 is connected to a driven disc 7 via a belt 8. The driven disc 7 is interference-fitted to the upper part of the outer wall of the hollow rotating shaft 4.

[0023] In this embodiment: the stirring mechanism is driven to rotate, the rotary motor 10 is running, the rotary motor 10 drives the active disk 9 at the output end to rotate, the active disk 9 drives the driven disk 7 to rotate through the belt 8, and the driven disk 7 can drive the rotating mechanism to rotate.

[0024] Please refer to this carefully. Figure 3 and Figure 4 The rotary spraying mechanism includes a connector 12 rotatably mounted on the bottom of the outer wall of the hollow rotating shaft 4 via a lower bearing 15. A sealing ring is installed at the rotatable connection between the hollow rotating shaft 4 and the connector 12. A rotary spray head 16 is integrally formed at the bottom of the connector 12. A liquid channel 17 is formed inside the rotary spray head 16 and is connected to the inner cavity of the hollow rotating shaft 4. The rotary spraying mechanism also includes a conical structure formed at the bottom of the lower bearing 15. The conical structure is wider at the top and narrower at the bottom. Multiple circumferentially equidistant rotary nozzles 13 are installed on the conical plate of the rotary spray head 16. The rotary nozzles 13 are set in an inclined downward position. The inner cavity of the rotary nozzles 13 is connected to the inner cavity of the liquid channel 17. The inclination direction of the rotary spray head 16 is the same as the rotation direction of the hollow rotating shaft 4.

[0025] In this embodiment: the second type of oil enters the hollow rotating shaft 4, enters the inner wall of the liquid channel 17 along the inner wall of the hollow rotating shaft 4, and enters multiple rotary nozzles 13 through the liquid channel 17, and is then sprayed out from the rotary nozzles 13. The reaction force generated by the second type of oil sprayed out from the rotary nozzles 13 will drive the rotary nozzles 16 to rotate. Since the tilt direction of the rotary nozzles 16 is the same as the rotation direction of the hollow rotating shaft 4, the generated reaction force causes the rotation direction of the rotary nozzles 16 to be opposite to the rotation direction of the hollow rotating shaft 4. Therefore, the sprayed second type of oil flows in the opposite direction to the oil being stirred in the mixing tank 1.

[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.
