[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0018] Embodiment 1, as Figure 1-4 As shown, a magnetically driven internal and external circulation device comprises a driving frame 1 and an inner ring frame 2, wherein the driving frame 1 can be rotatably transferred to the outer surface of the homogenizing chamber of the homogenizer, and the inner ring frame 2 can be rotatably transferred to the inside of the homogenizing chamber of the homogenizer; an outer magnetic ring 3 is fixedly mounted on the inner side surface of the driving frame 1, and a driving cylinder 4 is arranged on the outer side surface of the driving frame 1, and a telescopic shaft 41 of the driving cylinder 4 is connected to the outer side surface of the driving frame 1, so as to drive the driving frame 1 to rotate on the outer surface of the homogenizing chamber of the homogenizer; an inner magnetic ring 5 is installed below the side surface of the inner ring frame 2, and the position of the inner magnetic ring 5 corresponds to that of the outer magnetic ring 3, and a plurality of blind plates 6 are arranged on the inner side of the upper surface of the inner ring frame 2, and the blind plates 6 correspond to the inner circulation flow channel 7 of the homogenizer.

[0019] Working principle:

[0020] During use, the driving cylinder 4 is controlled to drive the telescopic shaft 41 to perform telescopic movement, thereby driving the driving frame 1 to rotate on the outer surface of the homogenizing chamber, and then driving the outer magnetic ring 3 on the inner side of the driving frame 1 to rotate around the homogenizing chamber, and then through the magnetic cooperation between the outer magnetic ring 3 and the inner magnetic ring 5, the outer magnetic ring 3 can be moved to drive the inner magnetic ring 5 to follow the movement, and then drive the entire inner ring frame 2 to rotate inside the homogenizing chamber of the homogenizer. When it rotates to the specified position, the blind plate 6 on the inner ring frame 2 just blocks the inner circulation channel 7. At this time, the inner circulation channel 7 is blocked, and the material can only go out through the external outlet, so the homogenizer starts the external circulation mode. When the driving cylinder 4 is controlled to drive the telescopic shaft 41 to extend and retract, thereby driving the driving frame 1 and the outer magnetic ring 3 to rotate around the homogenizing chamber, and then driving the inner magnetic ring 5 to move to the specified position with the outer magnetic ring 3, the blind plate 6 on the inner ring frame 2 is staggered with the inner circulation channel 7, and the inner circulation channel 7 is opened. At this time, the valve of the external outlet is closed, and the material can only go out from the internal channel, and the homogenizer starts the internal circulation mode.

[0021] The entire process realizes the switching between the internal circulation mode and the external circulation mode through the magnetic attraction of the outer magnetic ring 3 and the inner magnetic ring 5, so as to meet the process requirements of 100% circulation of internal flow and 100% circulation of external flow.

[0022] Embodiment 2, as a further preferred embodiment of embodiment 1, a support frame 42 is installed on the rear side of the driving cylinder 4, the driving cylinder 4 is connected to the homogenizer through the support frame 42, the front side of the driving cylinder 4 is movably connected to one end of the telescopic shaft 41, the other end of the telescopic shaft 41 is fixedly connected to a hinge column 43, a hinge through hole is opened on the surface of the hinge column 43, a hinge shaft 44 is installed in the hinge through hole, a hinge seat 45 is fixedly installed on the outer side of the driving frame 1, and the hinge column 43 is movably connected to the hinge seat 45 through the hinge shaft 44.

[0023] Therefore, during use, the telescopic shaft 41 is driven to perform telescopic movement by driving the air cylinder 4, thereby driving the articulated column 43 to perform telescopic movement. Since the end of the articulated column 43 is rotatably connected to the articulated seat 45 via the articulated shaft 44, when the articulated column 43 performs telescopic movement, the articulated transmission action of the articulated shaft 44 and the articulated seat 45 can be used to convert it into a rotational movement of the drive frame 1, thereby driving the outer magnetic ring 3 to rotate around the homogenizing cavity.

[0024] Embodiment 3, as a further preferred solution of embodiment 1, both ends of the hinge column 43 pass through the hinge seat 45 and are engaged with the limit card 46. In this embodiment, limit card slots can be provided at both ends of the hinge column 43, so when in use, both ends of the hinge column 43 can be respectively passed through the hinge seat 45, and then engaged in the limit card slots through the limit card 46, thereby achieving the clamping and fixing of the hinge column 43, and when disassembly is required, only the limit card 46 needs to be taken out to separate the hinge column 43 from the hinge column 43. Convenient and quick.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
