Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydrogel processing, in particular to a hydrogel gelling device. Background Art
[0002] Hydrogel is a type of extremely hydrophilic three-dimensional network structure gel that swells rapidly in water and can retain a large volume of water in this swollen state without dissolving.
[0003] Due to the existence of a cross-linked network, hydrogels can swell and retain a large amount of water. The amount of water absorbed is closely related to the degree of cross-linking. The higher the degree of cross-linking, the lower the water absorption. This property is very similar to a soft tissue. The water content in the hydrogel can be as low as a few percent or as high as 99%. The aggregate state of the gel is neither completely solid nor completely liquid.
[0004] In the process of preparing hydrogel gelling equipment, it is generally necessary to mix the raw materials. However, in the existing hydrogel gelling equipment, the mixing device is mostly connected to the equipment of other processes as a whole, which is not convenient for use and maintenance. Moreover, most of the mixing devices are only provided with a single rotating stirring device, which can often only rotate in one direction, resulting in a relatively low mixing efficiency. In addition, long-term stirring will cause part of the raw materials to adhere to the inner wall of the mixing tank, and it cannot be processed in time, resulting in the inconvenience of subsequent cleaning.

[0009] The center of the cover ring plate is rotatably connected to a rotating circular plate, and the rotating circular plate is rotatably connected to two stirring shafts, and the top ends of the two stirring shafts are fixedly sleeved with planetary gears;
[0010] The upper surface of the cover ring plate is fixedly connected with an inner gear ring, and the planetary gears are meshed with teeth on the inner surface of the inner gear ring.

A mixing barrel is provided on the upper surface of the heating platform, and the mixing barrel is located below the planetary stirring device, and the lower ends of the stirring shafts extend into the mixing barrel.
[0013] Preferably, a shear stirring mechanism is fixedly connected to the upper ends of the two stirring shafts, and the shear stirring mechanism comprises two stirring plates, which are arranged in a cross shape and fixedly connected to the lower ends of the stirring shafts.
[0014] Preferably, the stirring plates on the two shear stirring mechanisms are respectively provided with corresponding shear grooves, and the two corresponding stirring plates cross-extend into the shear groove of the other stirring plate.
[0015] (III) Beneficial effects
[0016] Compared with the prior art, the utility model provides a hydrogel forming device, which has the following beneficial effects:
[0017] 1. The hydrogel gelling equipment starts the motor, which drives the two stirring shafts and the stirring plates thereon to rotate in the opposite direction, so as to fully stir the hydrogel raw materials in the mixing barrel. At the same time, since the two stirring plates on the two shear stirring mechanisms cross and extend into the shear groove of the other stirring plate, the two stirring plates can be continuously overlapped and separated when rotating in the opposite direction during stirring, just like having multiple pairs of scissors, so that the hydrogel raw materials in the mixing barrel can be continuously sheared and stirred, and finally completely mixed.

The hydrogel gelling equipment can continuously stir the hydrogel raw materials in the mixing barrel by two stirring shafts rotating in opposite directions through the shear stirring device, and can effectively distribute the hydrogel raw materials to the entire mixing system, so that the distribution of the raw materials is more uniform. Moreover, since the outer contours of the two stirring plates fit the inner wall of the mixing barrel when rotating, the hydrogel raw materials in the mixing barrel attached to the inner wall of the mixing barrel can also be uniformly stirred, thereby improving the mixing efficiency of the hydrogel raw materials to a certain extent.
