[0035] Example

[0036] like Figures 1-5As shown, this embodiment provides a mixing device for mixing oils, including a frame. The frame includes a base 100 and a lifting mechanism 200. The base 100 serves as the bottom support for the mixing device. Four universal casters 101 are provided around the bottom of the base 100 for easy movement and handling. The lifting mechanism 200 is fixed to the surface of the base 100 and is used to drive the mixing mechanism 400 to move up and down, allowing it to extend into or out of the mixing tank 300. The mixing tank 300 is placed on the surface of the base 100. Several ribs 301 are fixed to the inner wall of the mixing tank 300. During the mixing process, the ribs 301 can break up the oil stratification and prevent high-density liquid oil from continuously separating during the mixing process. Rotating in one direction prevents thorough mixing. The lifting mechanism 200 is connected to the stirring mechanism 400, which includes a drive assembly 401, a rotating shaft 402, and a stirring component. The drive assembly 401 is fixed to the lifting mechanism 200 and is connected to the rotating shaft 402, driving the rotating shaft 402 to rotate at high speed. The stirring component is located at the bottom of the rotating shaft 402 and rotates at high speed with the rotating shaft 402 to stir the material in the mixing tank 300. Furthermore, the bottom of the rotating shaft 402 is provided with an adjustment mechanism to adjust the angle of the stirring component, allowing the oil to dynamically adjust the angle of the stirring component during the mixing process, thereby improving the mixing efficiency.

[0037] Specifically, the stirring assembly includes a lifting component 403, a connecting rod 404, and a stirring component 405. The lifting component 403 has a ring-shaped structure, and multiple hinge seats are arranged in a circular array on its side. There are multiple connecting rods 404, with one end of each connecting rod 404 hinged to a hinge seat and the other end connected to the stirring component 405. The lifting component 403 is movably disposed inside the rotating shaft 402. An adjustment hole is provided on the side of the rotating shaft 402 at a position corresponding to the connecting rod 404. The height of the adjustment hole allows the connecting rod 404 to swing. The middle part of the connecting rod 404 is rotatably connected to the adjustment hole via the rotating shaft. When the lifting component 403 moves up and down, the connecting rod 404 can swing up and down around the rotating shaft, thereby driving the stirring component 405 to swing and change the angle between the stirring component 405 and the rotating shaft 402. The position of the stirring component 405 can be dynamically adjusted during the stirring process, thereby improving the mixing efficiency.

[0038] Furthermore, such as Figure 6As shown, the agitator 405 includes a cylindrical body 4051, which has a funnel-like structure. The cylindrical body 4051 has a conical inlet 4052 and a conical outlet 4053 at its two ends, respectively. The inner diameter of the cylindrical body 4051 gradually decreases from the conical inlet 4052 to the conical outlet 4053. During agitation, the accelerated laminar flow at the conical outlet and the turbulent flow generated by the dynamic pressure in opposite directions at the conical inlet meet during the circular motion, resulting in dynamic mixing and improving mixing efficiency.

[0039] Specifically, the adjustment mechanism includes a cylinder mounting bracket 501, an adjusting cylinder 502, and a drive shaft 503. The cylinder mounting bracket 501 is fixed to the bottom end of the rotating shaft 402, and the adjusting cylinder 502 is fixed to one side of the cylinder mounting bracket 501. The output shaft of the adjusting cylinder 502 is connected to the drive shaft 503 through a coupling. The drive shaft 503 is connected to the lifting member 403 through one end of the adjusting cylinder 502. The adjusting cylinder 502 drives the drive shaft 503 to move up and down, thereby driving the connecting member to move up and down, causing the connecting rod 404 to swing around the rotating shaft, thereby changing the angle of the stirring member 405.

[0040] Specifically, the lifting mechanism 200 includes a telescopic rod 201, a cylinder fixing plate 202, a lifting cylinder 203, and a motor fixing plate 204. The telescopic rod 201 consists of two hollow sleeves fixed to the base 100 and two solid optical shafts movably connected inside the sleeves. The two ends of the cylinder fixing plate 202 are fixed to the fixed ends of the telescopic rod 201. The lifting cylinder 203 is fixed on the cylinder fixing plate 202. The motor fixing plate 204 is fixed to the movable end of the telescopic rod 201. The output shaft of the lifting cylinder 203 is fixed to the motor fixing plate 204. The lifting cylinder 203 drives the motor fixing plate 204 to lift. The motor fixing plate 204 is used to fix the drive assembly 401. In this embodiment, the drive assembly 401 is a geared motor.

[0041] In one embodiment, the liquid grease cannot be aerated during stirring, otherwise it will accelerate the deterioration of the grease. In this embodiment, an air extraction mechanism 600 is provided, including a vacuum pump 602 and a sealing cover 601. The sealing cover 601 is fixed to the motor fixing plate 204 and can be raised and lowered with the motor fixing plate 204 to close or open the top opening of the stirring tank 300. The output shaft of the drive component 401 passes through the sealing cover 601 and is connected to the rotating shaft 402. The sealing cover 601 is provided with a vacuum interface 6011 for connecting to a vacuum pipe. The vacuum pump 602 is connected to the vacuum interface 6011 through a pipe. During the stirring process, the vacuum pump 602 slowly extracts the air inside the stirring tank 300 to prevent air from mixing into the grease during stirring and to ensure the quality of the grease.

[0042] In one embodiment, the temperature of the grease gradually increases during stirring. This embodiment includes a cooling mechanism 700, comprising a liquid cooling pump 701 and a heat dissipation device 702. A liquid cooling pipe 302 is installed inside the stirring tank 300, embedded in the side wall of the stirring tank 300. An inlet 303 is located at the bottom of the side of the stirring tank 300, and an outlet 304 is located at the top. The two ends of the liquid cooling pipe 302 are respectively connected to the inlet 303 and the outlet 304. The output end of the liquid cooling pump 701 is connected via a pipe. The coolant is connected to the heat dissipation device 702. The output end of the heat dissipation device 702 is connected to the liquid inlet 303 through a pipe, and the liquid outlet 304 is connected to the input end of the liquid cooling pump 701 through a pipe, forming a loop. The liquid cooling pump 701 delivers the coolant through the heat dissipation device 702 for cooling, and then inputs it into the liquid cooling pipeline 302 from the liquid inlet 303 to cool the grease inside the mixing tank 300. Finally, the coolant flows out from the liquid outlet 304 and returns to the liquid cooling pump 701, and is delivered to the heat dissipation device 702 for cooling, thus continuously circulating.

[0043] Furthermore, a temperature probe is embedded inside the mixing tank 300. The temperature probe detects the temperature of the grease, and the cooling mechanism 700 is activated to cool the grease based on the rate of temperature rise, so that the grease can be maintained within a certain temperature range and the grease can be prevented from deteriorating due to excessive temperature.

[0044] Furthermore, there are four ribs 301 arranged in a circular array around the inner wall of the mixing tank 300, and / or the thickness of the ribs 301 is 2-5 cm. The thickness of the ribs 301 is sufficient to prevent them from breaking due to grease impact, and the four ribs 301 can effectively break up grease stratification and improve mixing efficiency.

[0045] The working principle of this invention is as follows: After the stirring mechanism 400 is raised by the lifting mechanism 200, the stirring tank 300 containing the oil to be mixed is placed on the base 100. Then, the stirring mechanism 400 and the sealing cover 601 are lowered by the lifting mechanism 200, and the sealing cover 601 seals the top opening of the stirring tank 300. The reduction motor is started to drive the rotating shaft 402 to rotate, which in turn drives the stirring component 405 to rotate and stir the oil. During the stirring process, the adjusting cylinder 502 drives the transmission shaft 503 to rise and fall, thereby driving the connecting component to rise and fall, and causing the connecting rod 404 to swing around the rotating shaft, thereby changing the angle of the stirring component 405. This dynamically adjusts the stirring assembly, changes the stirring angle and position, and accelerates the mixing of the oil. During the stirring process, the vacuum pump 602 is used to remove excess air to prevent the oil from mixing with a large amount of air and accelerating deterioration. During the stirring process, the temperature probe continuously monitors the oil temperature, and the cooling mechanism 700 is activated in advance to cool the oil based on the temperature change curve. This invention not only improves mixing efficiency, but also ensures that the oil does not deteriorate through operations such as vacuuming and cooling.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
