[0002] The stirring paddle in chemical equipment is generally used to stir mixed material, and the existing stirring paddle is generally of one-piece structure, and only the lower part is provided with paddle, so that it cannot achieve good stirring effect on large storage tank equipment.

[0003] The utility model patent with publication number CN219964545U discloses a large-diameter lining storage tank coated with spring four fluorine PTFE stirring paddle, and the technical points are to include circumferential stirring assembly, transverse stirring assembly and bottom stirring assembly to solve the technical problem of poor stirring effect of general stirring paddle on large-diameter lining storage tank. However, the stirring paddle provided by the utility model lacks a structure for making liquid flip up and down, which makes the stirring paddle prone to stratification similar to oil-water mixture or cutting similar to gel block when stirring relatively viscous liquid, and cannot fully stir the relatively viscous liquid. SUMMARY

[0004] The utility model aims at overcoming the technical problem that the existing stirring paddle cannot flip liquid up and down, and has poor stirring effect on viscous liquid.

[0005] To achieve the above-mentioned purpose, the technical scheme provided by the utility model is as follows:

[0006] A stirring paddle that flips liquid up and down includes a storage tank cover and a stirring shaft that passes through the storage tank cover. The stirring shaft is connected with the main shaft of a motor. The stirring shaft has a worm structure. A fixed frame extends downward from the storage tank cover. The fixed frame is rotationally provided with a worm wheel that engages with the worm. The side of the worm wheel is provided with a flip plate.

[0007] To facilitate the installation and use of the stirring paddle, the preferred technical scheme of the utility model includes that the fixed frame is provided with a rotating hole. The worm wheel is axially fixedly provided with a rotating shaft. The rotating shaft is provided with rotating heads that are adapted to the rotating hole.

[0008] Further, the storage tank cover has a certain thickness. The storage tank cover is also provided with a mounting hole. The upper end of the fixed frame is provided with a positioning hole. When the fixed frame passes through the mounting hole upwardly, a positioning pin is clamped into the positioning hole to fix the fixed frame. The height of the positioning hole is adapted to the engagement and installation of the worm wheel and the worm.

[0009] Further, the mounting hole is obliquely arranged. The oblique hole is adapted to the fixed frame.

[0010] In order to better realize the function of up and down turning of the viscous liquid, the technical scheme further comprises that the worm wheel is provided with the turning plate only on the same side, when the turning plate is provided on both sides, the length of the turning plate also needs to consider that the movement route of the adjacent worm wheel connecting the turning plate cannot interfere, and the length of the turning plate can be prolonged to the position of the adjacent worm wheel only by providing the turning plate on the same side.

[0011] Further, the worm wheel is provided with the turning plate on both sides.

[0012] Further, the turning plates of the worm wheels are arranged along the rotation shafts of the worm wheels, the turning plates arranged in the array are of the same structure, and the difference is that the rotation actions between each worm wheel have a certain phase difference, that is, the turning plates of each worm wheel have a phase difference. Since the same worm gear is used to drive the worm wheels, the rotation angles in a unit time are the same, and the phase difference between the turning plates avoids the action interference between the turning plates.

[0013] In order to realize the circumferential stirring, the technical scheme further comprises that the bottom end of the stirring shaft is further provided with a bottom stirring paddle.

[0014] Further, the stirring shaft is further provided with an arc-shaped paddle.

[0015] In order to prevent corrosion and prolong the service life of the stirring paddle, the technical scheme further comprises that the stirring paddle has a plastic layer, and the stirring paddle is preferably made of nylon material.

[0028] The specific embodiments of the utility model will be further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot be used to limit the protection scope of the utility model. Example 1

[0029] Please refer to Figures 1-2 , a stirring paddle that turns up and down, comprising a tank cover 1 and a stirring shaft 2 passing through the tank cover 1, the stirring shaft 2 is connected with the motor main shaft, the stirring shaft 2 has a worm 4 structure, the tank cover 1 is also detachably connected with a fixing frame 3 through a mounting hole 10, the fixing frame 3 is rotatably installed with a worm gear 5 engaging the worm 4 through rotary heads 8 arranged at both ends of the rotary shaft 6 and rotary holes 7 arranged on the fixing frame 3, and the worm gear 5 is provided with a turning plate 9 on the side. The bottom end of the stirring shaft 2 is also provided with a bottom stirring paddle 12. The stirring shaft 2 is also provided with an arc paddle 13. The stirring paddle is fully coated with PTFE.

[0030] Please refer to Figure 3 , the tank cover 1 has a certain thickness and is obliquely provided with a mounting hole 10, a positioning hole 11 is arranged at the upper end of the fixing frame 3, when the fixing frame 3 passes through the mounting hole upwardly, a positioning pin is clamped into the positioning hole 11 to fix the fixing frame 3, the height of the positioning hole 11 matches the position of the worm gear 5 and the worm 4 on the stirring shaft 2, so as to realize the meshing installation of the worm gear and the worm.

[0031] Please refer to Figure 4 , the worm gear 5 is only provided with a turning plate 9 on the same side, it can be understood that the length of the turning plate 9 arranged on one side can also be continued to extend beyond the diameter of the worm gear without interfering with the movement.

[0032] Working principle: first, the fixed frame and the rotating shaft are assembled through the rotating head and the rotating hole, then the fixed frame is obliquely inserted through the mounting hole of the storage tank cover, and the positioning pin is clamped in the positioning hole, and at this time, the worm gear and the worm should be engaged. When the motor drives the stirring shaft 2 to work, the stirring shaft will rotate relative to the storage tank cover, at this time, due to the engagement of the worm gear and the worm, the worm gear will rotate on the rotating shaft, and the turning plate fixedly connected with the worm gear will also rotate, and in the storage tank, the rotation of the turning plate will drive the liquid, especially the relatively viscous liquid, to move up and down, thereby improving the problem of uneven stirring of viscous liquid. Due to the structural consideration and the need of actual production, the utility model has the advantages of simple structure. A plurality of accessories can be coated with polytetrafluoroethylene, or directly made of polytetrafluoroethylene to reduce corrosion and improve service life. In particular, the rotating head and the rotating hole are made of polytetrafluoroethylene, which can also fully utilize the excellent self-lubricating property of polytetrafluoroethylene to reduce wear after long-term rotation. The arc-shaped paddle arranged on the side surface of the stirring shaft stirs the liquid in the storage tank in the circumferential direction, and the bottom stirring paddle stirs the liquid at the bottom of the storage tank, so that the liquid in the storage tank tends to be uniform. Example 2

[0033] Please refer to Figure 5 The difference from example one is that the worm gear 5 is provided with a turning plate 9 on both sides. The rotating action between each worm gear 5 has a certain phase difference, and since the same worm 4 drives each worm gear 5, the rotating angle in unit time is the same, and the phase difference between the turning plates avoids the interference between the turning plates.

[0034] Taking two worm gears with two turning plates 9 symmetrically along the center of the rotating shaft 6 as an example, each worm gear 5 coincides with the current position after rotating 180°, and the phase difference between the two worm gears is preferably 180° / 2=90°.

[0035] Taking two worm gears with one turning plate 9 along the radius direction of the worm gear 5 as an example, each worm gear 5 coincides with the current position after rotating 360°, and the phase difference between the worm gears 5 is preferably 360° / 2=180°.

[0036] Please refer to Figure 6 The utility model also provides a stirring paddle with three turning plates.

[0037] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection range of the utility model.
