Their applications cover functions such as reducing pollutant emissions and enhancing product stability, and they are compatible with various petroleum derivatives such as lubricating oils and gasoline.
[0003] CN220758851U discloses a stirring device for producing petroleum additives. This device includes a stirring tank; a stirring shaft is installed in the stirring tank, and a stirring rod and a spiral stirring blade are mounted on the stirring shaft. The spiral stirring blade has several through holes. When the petroleum additive is pressed downwards by the spiral stirring blade, if the pressure is too high, the petroleum additive will move upwards through the through holes, reducing the volume of the petroleum additive clumps and ensuring the stable operation of the spiral stirring blade. Simultaneously, the passage of some clumps of petroleum additive through the through holes also means breaking up the clumps, which can improve stirring efficiency.
[0004] The existing petroleum additive production mixing device has the following disadvantages: the petroleum additive needs to be sampled before discharge, but the device lacks a sampling device. When sampling, the mixing tank needs to be opened, which is laborious and cumbersome due to the large size of the mixing tank.
[0005] Therefore, a circulating stirring device for preventing sedimentation of petroleum additives is proposed to solve the problems mentioned above. Utility Model Content

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.
[0025] Example:

A cover plate 2 is attached to the upper end of the stirring tank 1. A servo motor 6 is fixedly connected to the upper end of the cover plate 2. The lower end of the servo motor 6 is fixedly installed at the center of the upper end of the cover plate 2. A fixing rod 7 is fixedly connected to the output end of the servo motor 6 through the inner wall of the cover plate 2. Multiple stirring rods 8 are fixedly connected to the surface of the fixing rod 7. Multiple stirring blades 9 are fixedly connected to the surface of the fixing rod 7. A stirring plate 10 is fixedly connected to the bottom end of the fixing rod 7. A first sampling tube 12 is fixedly connected to the inner wall of the stirring tank 1. A sampling cylinder 14 is fixedly connected to the inner wall of the first sampling tube 12. A piston 21 is slidably sleeved on the inner wall of the sampling cylinder 14. A pull rod 18 is fixedly connected to the upper end of the piston 21. A spring 20 is sleeved between the piston 21 and the sampling cylinder 14. Multiple connecting rods 11 are fixedly installed on the inner wall of the stirring tank 1. A sealing cover 23 is sealed on the inner wall of the cover plate 2.
[0027] When the servo motor 6 controls the rotation of the fixed rod 7, it can simultaneously control the rotation of the stirring rod 8 and the stirring blade 9 and the stirring plate 10, thereby controlling the rotation of the petroleum additive in the stirring tank 1. By repeatedly rotating the petroleum additive to the top and then transferring it to the inner wall, the petroleum additive is circulated and stirred.
[0028] The inner wall of the cover plate 2 is provided with multiple through holes 4, and the inner wall of the mixing tank 1 is provided with multiple threaded holes 5. The multiple through holes 4 and the threaded holes 5 are positioned in a vertically opposite manner, and the cover plate 2 and the mixing tank 1 are connected by bolts 3.
[0029] When the bolt 3 is simultaneously inserted into the cover plate 2 and the mixing tank 1, a stable connection between the cover plate 2 and the mixing tank 1 is completed.
[0030] The bottom end of the spring 20 is fixedly connected to the upper end face of the piston 21, the top end of the spring 20 is fixedly connected to the inner wall of the sampling cylinder 14, and the surface of the pull rod 18 is fixedly connected to the first limiting plate 17, the lower end face of the first limiting plate 17 overlaps the upper end face of the sampling cylinder 14.
[0031] By setting the spring 20, when the spring 20 is no longer compressed, the spring 20 can reset the piston 21 by its own elastic force.
[0032] The lower end of the pull rod 18 is fixedly connected to the center of the upper end face of the piston 21, and the surface of the pull rod 18 is slidably sleeved inside the sampling cylinder 14.
[0033] By setting the lever 18, the movement of the piston 21 can be controlled;
[0034] The top end of the pull rod 18 is fixedly connected to the second limiting plate 16, and the top end of the pull rod 18 is fixedly connected to the center of the lower end face of the second limiting plate 16.
[0035] By setting the second limiting plate 16, it is convenient to operate when the pull rod 18 needs to be pulled.
[0036] The inner wall of the sampling cylinder 14 is provided with a first installation port 22, and a second sampling tube 15 is fixedly connected to the inner wall of the sampling cylinder 14.
[0037] By setting up a second sampling tube 15, it is convenient to sample petroleum additives;
[0038] The second sampling tube 15 has a second installation port 13 on its inner wall, and the sampling tube 14 has a through port 19 on its upper end face.
[0039] The working principle of the above embodiments is as follows:
[0040] In use, when the servo motor 6 is connected to the power supply and driven, the fixed rod 7 can simultaneously control the rotation of the stirring rod 8, stirring blade 9, and stirring disc 10, thereby driving the petroleum additives in the mixing tank 1 to rotate at high speed. Due to the force of the stirring blade 9, the petroleum additives rotate at high speed during rotation, forming a vortex. This causes the petroleum additives stationary at the bottom of the mixing tank 1 to move from the bottom to the inner wall, creating an upward force. Because the rotation of the stirring blade 9 forms a circular shape around the fixed rod 7, when the petroleum additives rise to a certain height, they will move downwards through the flow direction, thus achieving the purpose of circulating stirring. The stirring disc 10 can transport the petroleum additives at the bottom of the mixing tank 1 upwards, causing the bottom petroleum additives to rotate together with other petroleum additives, preventing sedimentation of the petroleum additives at the bottom of the mixing tank 1. During rotation, the stirring rod 8, by misaligning with the connecting rod 11, can disperse clumps of petroleum additives by flowing between the stirring rod 8 and the connecting rod 11. When sampling is required, a pre-prepared sampling bottle is inserted into one end of the second sampling tube 15. Then, the piston 21 is controlled by the second limiting plate 16 to slide upward on the inner wall of the sampling cylinder 14. The stirred petroleum additives are drawn into the second sampling tube 15 by negative pressure and simultaneously transported into the sampling bottle. This device is not only simple and convenient during sampling, but also avoids contamination of the petroleum additives. After sampling of the petroleum additives is completed, the upward pull of the pull rod 18 is released, allowing the surface of the pull rod 18 to slide inside the sampling cylinder 14. The spring 20 controls the piston 21 to return to its original position through its elastic force, so that the upper part of the piston 21 is below the first mounting port 22, facilitating sampling again.
[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
