Description

Technical Field

[0001] The utility model relates to the technical field of stirring instruments and equipment, in particular to a stirring centrifugal structure. Background Art

[0002] The traditional stirring structure mainly adopts a one-way or multi-directional column stirring rod, and the stirring rod is superimposed with blades on the side to expand the stirring area. Intermittent stirring and on-off stirring methods are usually adopted. During the stirring process, the blades follow the movement mechanically, and the stirring range and height are always fixed. There is no local stirring effect, so neither intermittent stirring nor on-off stirring can stir the fluid in a small range, so its stirring effect cannot be optimized. In addition, at the moment of stopping rotation, the main rotating shaft will be subjected to axial stress impact due to the inertia of the fluid, which is easy to damage the stirring structure.

[0003] To achieve the above objectives, the present invention provides a centrifugal structure under stirring, which can solve the problems raised in the above background technology. Utility Model Content

[0017] The utility model generates a rotating centrifugal force to one end of the shaft seat disc by driving the main rotating shaft, so that the centrifugal disc connected to the bottom thereof rotates and centrifuges around the shaft seat disc, thereby expanding the basic area of ​​stirring and the stirring effect. In addition, by causing the centrifugal disc to generate secondary centrifugation during stirring, the local fluid can be stirred.

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] Please refer to the attached Figure 1-3 , comprising a main rotating shaft 1 and a driving motor 2, wherein the main rotating shaft 1 is connected to the lower output end of the driving motor 2, a plurality of rotating brackets 101 are provided on the circumference of the main rotating shaft 1, a shaft base disc 104 is provided at the rotating distal end of the rotating bracket 101, a centrifugal disc 106 is connected to the bottom of the shaft base disc 104, the centrifugal disc 106 and the shaft base disc 104 have different axial positions, and the rotation axis of the centrifugal disc 106 is at the same position as that of the shaft base disc 104;

[0031] The upper portion of the shaft seat disc 104 is connected to the bottom of the distal end of the rotating bracket 101, and a connecting disc is provided at the bottom of the shaft seat disc 104;

[0032] The centrifugal disc 106 includes an inner connecting disc 108 and an outer connecting disc 107. A connecting groove 109 is provided between the outer connecting disc 107 and the inner connecting disc 108. The connecting groove 109 guides the bottom of the bottom connecting disc of the shaft seat disc 104. The inner wall and the outer wall of the outer connecting disc 107 are both provided with inward grooves, which are used to cooperate with and guide the connecting disc at the bottom of the shaft seat disc 104.

[0033] Multiple groups of the rotating brackets 101 are fixed to the circumference of the main rotating shaft 1 and are spaced apart in an upper and lower manner, and the rotation angle between two adjacent rotating brackets 101 is 180 degrees;

[0034] The inner connecting plate 108 is provided with a hydrophobic plate 112 that passes through the inner connecting plate 108 from top to bottom.

[0035] Example 1: The stirring centrifugal method of the present invention is as follows: the original power of stirring is driven by the driving motor 2 to drive the main rotating shaft 1 to rotate, and there are two methods: programmed intermittent rotation, at this time it is necessary to maintain the angle range of a single rotation and the axial force applied to enable the centrifugal disk 106 of a single circle to rotate, when the axial rotation force is sufficient, the split bracket 103 follows the rotation, driving the centrifugal disk 106 to rotate around the main rotating shaft 1, when the outside and inside of the centrifugal disk 106 are in contact with the fluid, it carries a part of the fluid to continue rotating, and then its own weight increases, because the rotational contact point of the centrifugal disk 106 and the shaft seat disk 104 is not the center origin but the annular connecting groove 109, thereby generating local centrifugal force, the centrifugal disk 106 begins to rotate around the central axis of the shaft seat disk 104, at this time, the centrifugal disk 106 is located around the axis of the shaft seat disk 104 While the centrifugal disc 106 is rotating, it moves in a regular arc around the circumference of the main rotating shaft 1. When the intermittent motion is paused, the centrifugal disc 106 still maintains a certain centrifugal force, and can rely on the centrifugal force to offset the stirred flow, thereby reducing the impact of axial stress on the main rotating shaft 1. In addition, the intermittent continuous rotation method and the continuous rotation of the main rotating shaft 1 can make the centrifugal disc 106 continuously rotate centrifugally. Through the staggered distribution structure of the rotating bracket 101, better stirring contact can be formed between different hierarchical structures. The 180-degree distribution method and the reduced power requirement of the drive motor 2 can assist the rotation by the centrifugal inertia force. At this time, the centrifugal disc 106 is assisted in generating centrifugal force by introducing liquid from the periphery of the liquid channel 111, so that the centrifugal disc 106 still maintains a local centrifugal effect. The brush 105 is only used for self-cleaning the liquid channel 111 position.

[0036] Please refer to Figure 1-4The rotating bracket 101 includes a central disk 102 and two split brackets 103. The split brackets 103 are mounted on the peripheral side of the central disk 102. The shaft seat disc 104 is fixed below one end of the split bracket 103 away from the central disk 102.

[0037] The two split brackets 103 are located in the same horizontal plane and are symmetrical in cross section with respect to the central axis of the main rotating shaft 1;

[0038] An external reverse liquid tray 110 is provided on the outside of the centrifugal tray 106. A liquid passage 111 is provided on one side of the external reverse liquid tray 110 and communicates with the interior of the centrifugal tray 106. The length of the split bracket 103 is greater than the diameter of the external reverse liquid tray 110.

[0039] A brush 105 is provided on the circumference of the central disk 102 , and the brush 105 is adapted to the rotation stroke of the external reverse liquid disk 110 .

[0040] Embodiment 2: This device can increase the load of the main rotating shaft 1 by using the centrifugal force of the separated outer centrifugal disk 106 and make the main rotating shaft 1 and the centrifugal disk 106 a unified body at the moment of stopping, thereby reducing the impact of the instantaneous stop of the flow on the driving end of the main rotating shaft 1. The liquid passage 111 can conduct the fluid to the connecting groove 109 when the centrifugal disk 106 rotates to increase the load, increase the centrifugal force, and improve the local centrifugal effect. In addition, the overall internal load makes the main rotating shaft 1 fit more smoothly with the fluid in the cylinder, maintains the integrity of the main rotating shaft 1 and the centrifugal disk 106, and can maintain its own rigidity at the moment of stopping, reducing the impact of axial stress on the main rotating shaft 1 and the drive motor 2 (in addition, since the centrifugal disk 106 is movable, when the centrifugal force of the fluid impacts the centrifugal disk 106, it can be directly offset by the original rotating centrifugal offset, or directly passively accept the impact to offset the impact of the fluid).

[0041] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
