Specific embodiments

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0029] Embodiment 1

[0030] Figures 1 - 4 The schematic diagram of the overall structure as a specific embodiment of the present utility model is shown. Figures 1 - 4 Among them, it includes a crystallization support kettle 1, and a first stirring layer 2, a second stirring layer 3, a third stirring layer 4, and a fourth stirring layer 5 installed on the inner wall of the crystallization support kettle 1. The first stirring layer 2 and the second stirring layer 3 are symmetrically distributed with the third stirring layer 4 and the fourth stirring layer 5.

[0031] A reverse rotation motor 6 and a forward rotation motor 7 are respectively installed at the upper and lower ends of the crystallization support kettle 1. Among them, the reverse rotation motor 6 and the forward rotation motor 7 rotate in opposite directions. Rotating connection rods 13 are installed at the output ends of the reverse rotation motor 6 and the forward rotation motor 7. A connection support cylinder 8 is installed between the two rotating connection rods 13, and the connection support cylinder 8 is fixedly connected to the lower rotating connection rod 13, and the connection support cylinder 8 is rotatably connected to the upper rotating connection rod 13;

[0032] The first stirring layer 2 and the second stirring layer 3 are rotatably connected to the upper rotating connection rod 13, and the third stirring layer 4 and the fourth stirring layer 5 are rotatably connected to the lower rotating connection rod 13. Among them, the upper surfaces of the first stirring layer 2 and the third stirring layer 4 are both concave from the outside to the middle, and the upper surfaces of the second stirring layer 3 and the fourth stirring layer 5 are both convex from the outside to the middle;

[0033] The upper surfaces of the first stirring layer 2 and the third stirring layer 4 are both rotatably provided with concave stirring rods 9, and the upper surfaces of the second stirring layer 3 and the fourth stirring layer 5 are both rotatably provided with convex stirring rods 14. Moreover, circulation guiding grooves 15 are formed on the first stirring layer 2, the second stirring layer 3, the third stirring layer 4, and the fourth stirring layer 5, and the four circulation guiding grooves 15 are arranged in a staggered manner.

[0034] When the device operates, by rotating and stirring and flipping the fatty acid layer by layer on the first stirring layer 2, the second stirring layer 3, the third stirring layer 4, and the fourth stirring layer 5, the full utilization of the stirring device is improved, and the stirring during the crystallization of the fatty acid is further made sufficient. Specifically, the fatty acid first flows to the inside and outside of the first stirring layer 2, and at the same time, the plurality of concave stirring rods 9 rotate simultaneously, so that the fatty acid is stirred and flipped and then flows to the middle part inside the second stirring layer 3 below. Then, under the simultaneous rotation of the plurality of convex stirring rods 14, the fatty acid is stirred and flipped again, and then flows to the middle and outside of the third stirring layer 4 below under the support of the circulation guiding groove 15. Secondly, under the rotational support of the third stirring layer 4 and the fourth stirring layer 5, and under the circulation guiding of the circulation guiding groove 15, the fatty acid is repeatedly stirred and flipped. At the same time, by setting the first stirring layer 2 and the third stirring layer 4, and the second stirring layer 3 and the fourth stirring layer 5 into a shape with a middle depression and a protrusion, the accurate flow direction of the fatty acid is ensured, so that it is fully cooled and crystallized under the cooling effect of the existing device, thereby achieving the effect of rotating and utilizing each layer of the stirring device, and being not affected by the volume of the fatty acid itself, and improving the efficient utilization of the device.

[0035] Figure 3 Shown is a structural schematic diagram of the stirring and flipping method as a specific embodiment of the present invention. Figure 3 Among them, there are several concave stirring rods 9 and convex stirring rods 14, and inclined surface guiding blocks 10 are installed on the lower half of one side of the concave stirring rods 9 and the convex stirring rods 14, and arc surface guiding blocks 11 are installed on the upper half of one side of the concave stirring rods 9 and the convex stirring rods 14. The arc surface guiding blocks 11 are located above the rotating support cylinder 12.

[0036] The inclined surface guiding blocks 10 and the arc surface guiding blocks 11 on one side of each concave stirring rod 9 and convex stirring rod 14 are all in the same orientation.

[0037] When the concave stirring rods 9 and the convex stirring rods 14 rotate, the inclined support of the inclined surface guiding blocks 10 at their lower ends provides the movement and accumulation of the material, and the arc-shaped support of the arc surface guiding blocks 11 at their upper ends enables the accumulated material to flow in an arc shape. Thus, under the cooperation of the inclined surface guiding blocks 10 and the arc surface guiding blocks 11, the effect of stirring and flipping is achieved.

[0038] Figure 2 and Figure 4Shown is a schematic structural diagram of the rotation mode as a specific embodiment of the present utility model. Figure 2 and Figure 4 In Figure 2 and Figure 4 , several rotating support cylinders 12 are installed outside the rotating connecting rod 13. The rotating support cylinders 12 are fixedly connected to the concave stirring rods 9 on the same horizontal plane and the convex stirring rods 14 on the same horizontal plane at the same time.

[0039] The reverse rotation motor 6 drives the concave stirring rods 9 and the convex stirring rods 14 in the upper half of the device to rotate counterclockwise through the rotating connecting rod 13 and the rotating support cylinders 12. The forward rotation motor 7 drives the concave stirring rods 9 and the convex stirring rods 14 in the lower half of the device to rotate clockwise through the rotating connecting rod 13 and the rotating support cylinders 12.

[0040] Under the respective drives of the reverse rotation motor 6 and the forward rotation motor 7, the effects of rotating the concave stirring rods 9 and the convex stirring rods 14 on both sides in opposite directions are achieved. Thus, while making full use of the stirring device, the full stirring effect of fatty acids in different directions is improved, and the high-efficiency, continuous and stable stirring of fatty acids by the device is enhanced.

[0041] Figure 2 Shown is a schematic three-dimensional structure diagram of the stirring and circulation as a specific embodiment of the present utility model. Figure 2 In Figure 2 , the circulation guide grooves 15 are located in the middle of the upper surfaces of the first stirring layer 2 and the third stirring layer 4, and the circulation guide grooves 15 are located outside the upper surfaces of the second stirring layer 3 and the fourth stirring layer 5. Moreover, the concave stirring rods 9 and the convex stirring rods 14 in the upper half are oriented in the opposite direction to the concave stirring rods 9 and the convex stirring rods 14 in the lower half.

[0042] By arranging the circulation guide grooves 15 at the lowest horizontal positions on the upper surfaces of the first stirring layer 2 and the third stirring layer 4, and between the second stirring layer 3 and the fourth stirring layer 5, the accuracy of the circulation of fatty acids after being stirred is ensured. And by arranging a plurality of circulation guide grooves 15 at the rear end of the stirring direction, it is ensured that each layer of the stirring device can fully stir the fatty acids. At the same time, by setting the orientations of the concave stirring rods 9 and the convex stirring rods 14 on both sides to be the same as the rotation directions of their respective stirring devices, the stability during multi-directional stirring of fatty acids is ensured, and the full utilization of the stirring device is further improved.

[0043] Working principle: With the support of the feed inlet on the crystallization support kettle 1, the fatty acid first flows to the outside of the inner part of the first stirring layer 2. At the same time, multiple concave stirring rods 9 rotate simultaneously, causing the fatty acid to be stirred and flipped and then flow to the middle part of the inner part of the second stirring layer 3 below. Then, under the simultaneous rotation of multiple convex stirring rods 14, the fatty acid is stirred and flipped again. Then, with the support of the flow guiding groove 15, it flows to the outside of the middle part of the third stirring layer 4 below. Secondly, under the rotational support of the third stirring layer 4 and the fourth stirring layer 5, and with the flow guiding of the flow guiding groove 15, the fatty acid is repeatedly stirred and flipped. And by setting the first stirring layer 2 and the third stirring layer 4, and the second stirring layer 3 and the fourth stirring layer 5 to be concave and convex in the middle, the stability of the fatty acid flow direction is ensured, and it is fully cooled and crystallized under the cooling effect of the existing device.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
