[0006] The mixing tank is equipped with an inner rotating frame and an outer rotating frame, and the inner rotating frame and the outer rotating frame are connected by a driving mechanism;

[0007] The inner rotating frame and the outer rotating frame rotate in opposite directions and automatically switch between each other in stages. Both the inner rotating frame and the outer rotating frame are equipped with main stirring blades.

[0008] The interior of the mixing tank is connected to the output end of the additive conduit. A pre-stirring mechanism is provided below the output end of the additive conduit. The pre-stirring mechanism is mounted on the inner rotating frame and rotates in cooperation with the inner rotating frame.

[0009] The mixing tank has a central column at its center that coincides with its central axis and extends through both the inner and outer sides of the mixing tank. The part of the central column located inside the mixing tank is rotatably fitted with the outer rotating frame and the inner rotating frame from top to bottom.

[0010] The outer rotating frame includes an upper rotating ring coaxially sleeved on the outside of the central column and rotatably connected thereto. Several horizontally arranged upper crossbars are evenly fixedly connected to the outer side of the upper rotating ring in a radial direction. Each upper crossbar is rotatably connected to a vertically downward-facing outer rotating rod at the bottom of one end away from the upper rotating ring. Several main stirring blades are evenly coaxially sleeved on the outer side of each outer rotating rod from top to bottom.

[0011] The inner rotating frame includes a lower rotating ring coaxially sleeved on the outside of the central column and rotatably connected thereto. The lower rotating ring is located below the upper rotating ring. Several horizontally arranged lower crossbars are uniformly fixedly connected to the outer side of the lower rotating ring in a radial direction. Each lower crossbar is rotatably connected to a vertically downward-facing inner rotating rod at the bottom of its end away from the lower rotating ring. Several main stirring blades are uniformly coaxially sleeved on the outer side of each inner rotating rod from top to bottom.

[0013] The drive mechanism includes a first bevel gear coaxially fixedly connected to the bottom of the upper rotating ring and facing downward, and a second bevel gear coaxially fixedly connected to the top of the lower rotating ring and facing upward;

[0014] A connecting rod is fixedly connected to the center of the central column between the first bevel gear and the second bevel gear, passing through both sides of the central column. The central axis of the connecting rod is perpendicular to the central axis of the central column. The two ends of the connecting rod are coaxially rotatably connected to a third bevel gear and a fourth bevel gear arranged opposite to each other.

[0017] One end of the rack is hinged to one end of the pull rod, and the other end of the pull rod away from the hinged end is provided with a collar. The collar is coaxially sleeved on the outside of the vertically set column. The top of the column is rotatably connected to the bottom of the mounting plate set above the top of the mixing tank. A first transmission disc is coaxially sleeved on the outside of the column.

[0018] A drive motor is installed on the top of the mixing tank. The output shaft of the drive motor is coaxially fixedly connected to a second transmission disc. A first transmission belt is sleeved between the second transmission disc and the first transmission disc.

[0019] An additive tank is provided on the top of the mixing tank, and the additive tank is connected to an infusion pump. The output end of the infusion pump is connected to the input end of the additive conduit.

[0020] The drive shaft of the infusion pump is coaxially fixedly connected to a third transmission disc, and the output shaft of the drive motor is coaxially fixedly connected to a fourth transmission disc. A second transmission belt is sleeved between the third transmission disc and the fourth transmission disc.

[0021] The additive conduit is inserted from the center of the top of the central column and extends all the way to below the lower rotating ring;

[0022] The pre-stirring mechanism includes a first ring horizontally positioned below the output end of the additive conduit. The outer wall of the first ring is fixedly connected to the bottom of the lower rotating ring. A rotating sleeve is coaxially positioned at the center of the first ring. Several upper blades are uniformly fixedly connected between the outer wall of the rotating sleeve and the inner wall of the first ring.

[0023] A second ring is coaxially arranged below the first ring. The rotating sleeve is rotatably connected to a downward-facing rotating shaft. Several lower blades are uniformly fixedly connected between the bottom side of the rotating shaft and the inner wall of the second ring along the circumferential direction.

[0024] The outer side of the second ring is evenly provided with a number of external tooth blocks, and each of the inner rotating rods is fitted with a first gear at the same height on the outer side. The external tooth blocks mesh with a number of the first gears.

The second gear meshes with the internal tooth blocks on the inner rail, and the third gear meshes with the internal tooth blocks on the outer rail.

[0027] An mounting cylinder is rotatably connected between the upper rotating ring and the lower rotating ring, and the first bevel gear, the second bevel gear, the third bevel gear, and the fourth bevel gear are all located inside the mounting cylinder.

[0028] The additive conduit output end is equipped with a funnel-shaped nozzle with a wide opening facing downwards.

[0029] In practical use, the invention works as follows: First, fuel oil is added to the mixing tank through the inlet, and additives are added to the additive tank. The drive motor is started, and the first transmission belt drives the first transmission disc to rotate. The first transmission disc drives the pull rod to rotate, and the pull rod pulls the rack hinged to it. The rack drives the drive gear to rotate. When the pull rod is pulled away from the drive gear, the rack drives the drive gear to rotate counterclockwise. When the pull rod moves from the farthest point to the drive gear, the rack drives the drive gear to move clockwise. This cycle repeats. The drive gear drives the outer rotating frame to rotate synchronously in the same direction. At the same time, the first bevel gear drives the second bevel gear to rotate in the opposite direction through the third and fourth bevel gears. The second bevel gear drives the inner rotating frame to rotate in the opposite direction to the outer rotating frame. Simultaneously, with the cooperation of the second gear and the inner rail, the inner rotating rod drives the main stirring blade connected to it to rotate in the opposite direction to the rotation direction of the inner rotating frame. With the cooperation of the third gear and the outer rail, the outer rotating rod drives the main stirring blade connected to it to rotate in the opposite direction to the rotation direction of the outer rotating frame. The rotation direction automatically switches as the rotation directions of the inner and outer rotating frames change.

[0030] After the drive motor starts, it simultaneously drives the fourth transmission disc to rotate, and through the second transmission belt and the third transmission disc, it drives the delivery pump to inject the additive into the center of the mixing tank at a certain pressure. The additive is first initially stirred by the pre-stirring mechanism. After the initial stirring, the additive continues to be stirred by the main stirring blades to achieve a good stirring effect and prevent sedimentation. After stirring is completed, the oil outlet valve is opened to discharge the oil. The working process of the pre-stirring mechanism is as follows: the lower rotating ring drives the first ring to rotate, the first ring drives the upper blade to rotate, and the first gear rotates under the drive of the inner rotating rod's rotation. It also drives the second ring to rotate by meshing with the toothed blocks on the outside of the second ring, which in turn drives the lower blade to rotate for stirring.

[0031] The beneficial effects of this invention are as follows:

[0032] 1. This invention can efficiently and quickly mix additives with aviation fuel, ensuring thorough and uniform mixing, avoiding the formation of sediment, and guaranteeing the production quality of aviation fuel oil.

[0033] 2. The present invention ensures that the mixing process is fully effective by having the inner and outer rotating frames drive the main stirring blades to rotate in opposite directions and repeatedly switch back and forth.

[0034] 3. In this invention, the additive is injected into the fuel under a certain pressure instead of being placed on the top surface of the fuel for stirring. The pre-stirring mechanism can perform local stirring as soon as the additive enters the fuel, and further utilizes the rapid dispersion and fusion of the additive to accelerate the stirring efficiency and stirring effect.

[0035] 4. The present invention has a reasonable structural design. The power of the main stirring blade and the pre-stirring mechanism both come from the drive motor and are cleverly coordinated with each other through the structure. This not only saves the cost of the device but also ensures the consistency and coordination of the overall operation of the equipment. Attached Figure Description
