[0043] Embodiment 1

[0044] As shown in Figures 1-5 An aqueous ink hot stirring device, comprising a hot stirring ingredient cylinder 1. According to the existing mode, a heating resistor (not shown in the figure) is installed at the bottom of the hot stirring ingredient cylinder 1 to heat the material in the hot stirring ingredient cylinder 1. At the same time, a discharge pipe is connected to the bottom of the hot stirring ingredient cylinder 1 to realize the discharge of the ingredient after the ingredient.

[0045] In order to realize the full crushing, refining and dissolving of the material, especially the caked or particulate material, in the large-capacity ingredient hot stirring cylinder 1 during the ingredient stirring process, the above-mentioned hot stirring ingredient cylinder 1 is internally equipped with a rake frame fine stirring mechanism 2.

[0046] Specifically, the rake frame fine stirring mechanism 2 comprises a rake frame part, and the specific structure of the rake frame part comprises four rake frame rods 23 arranged in a circumferential array (adjacent rake frame rods 23 are fixedly connected through obliquely arranged inclined connecting rods 25 to increase stability), and a plurality of rake plates 24 are fixedly connected to the two sides of the rake frame rods 23.

[0047] In addition, the size of the rake plate 24 gradually increases from the outside of the rake frame rod 23 to the inside.

[0048] Specifically, the shape of the rake frame rod 23 is trapezoidal, that is, the length of the outer end side of the rake frame rod 23 is smaller than the length of the inner end side.

[0049] The rake plate 24 is fixedly welded to the two sides of the rake frame rod 23. The shape of the rake plate 24 is semicircular. Since the shape of the rake frame rod 23 is trapezoidal, the outer end is small and the inner end is large, therefore the size of the rake plate 24 gradually increases from the outside of the rake frame rod 23 to the inside, and the longitudinal cross-sectional shape of the rake plate 24 is semicircular, and the rake plate 24 is welded to the side walls on the two sides of the rake frame rod 23.

[0050] In this way, during the rotation of the rake frame part, the material is fully stirred by the rake plate 24 on the large rake frame rod 23, and the clumps or particles in the material are broken and refined by the shearing force of the rake plate 24, so as to promote the re-dissolution and dispersion into the material system.

[0051] The above-mentioned rake frame fine stirring mechanism 2 further comprises a central column 27 for fixing a plurality of rake frame rods 23, and the inner end of the above-mentioned rake frame rod 23 is fixedly welded to the side wall of the central column 27 through a plurality of welding rods 231.

[0052] Meanwhile, according to the existing rotary connection mode, the bottom of the central column 27 is fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the bottom of the hot stirring ingredient cylinder 1.

[0053] The rake frame fine stirring mechanism 2 further comprises a motor 21 for driving the rotation of the central column 27, and specifically, the central part of the cylinder opening of the hot stirring ingredient cylinder 1 is fixedly connected with a cross beam plate 11, and the motor 21 is fixedly installed at the central part of the central column 27; the output shaft of the motor 21 is fixedly installed at the top central part of the central column 27.

[0054] During the working process, under the driving of the motor 21, the central column 27 carries the rake frame part to rotate.

[0055] The above-mentioned rake frame part further comprises a plurality of inclined pull frames 26 for pulling and fixing the rake frame rods 23, and the outer end of the inclined pull frame 26 is welded to the outer end of the rake frame part, and the inner end is welded to the upper end of the central column 27.

[0056] The large-sized rake frame section maintains high stability under the pull of the inclined cable 26.

[0057] Meanwhile, in order to further refine and dissolve the material, a rake tooth structure is fixedly connected to the inclined frame 26;

[0058] Specifically, the rake tooth structure includes rake tooth plates 27 welded to the side walls of the inclined frame 26, and the outer side wall of the rake tooth plates 27 has a plurality of tooth-shaped protrusions 271. During the material mixing process, the tooth-shaped protrusions 271 of the rake tooth plates 27 are sharp and form multiple areas with large shear forces. Therefore, during the rotation process, the agglomerates or particles in the material system are further broken up and dissolved, thereby further improving the dissolution efficiency during the mixing process.

[0059] Example 2

[0060] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 1, during the material mixing process, the lumps and particles in the material are easily driven by the fluid to approach the side wall of the hot mixing batching cylinder 1. Since the material mixing part needs to maintain a safe gap with the side wall of the hot mixing batching cylinder 1, the particles and lumps accumulated near the side wall of the hot mixing batching cylinder 1 are difficult to break.

[0061] Therefore, in order to continue pushing the particles and agglomerates accumulated near the side wall of the hot mixing batching cylinder 1 toward the center of the hot mixing batching cylinder 1 and to promote the refinement, crushing and dissolution of the material being raked, an air-push stirring structure is provided at the edge of the hot mixing batching cylinder 1. The air-push stirring structure pushes and stirs the particles at the edge of the hot mixing batching cylinder 1 toward the center.

[0062] Specifically, the air-push stirring structure includes several airflow stirring tubes 32, each with several airflow holes facing the center of the hot-stirring batching cylinder 1. Simultaneously, the lower end of each airflow stirring tube 32 is integrally formed with a through-tube portion penetrating the hot-stirring batching cylinder 1, and these through-tube portions are connected by an annular pipe 31; the through-tube portion is connected to an air inlet pipe 33. A pumping device is connected to the air inlet pipe 33 in a conventional manner to pump air. Gas is ejected from the airflow holes, pushing the solid material accumulated and deposited on the sidewalls towards the center again, where it is dispersed and refined.

[0063] This process is repeated to achieve solid agglomeration and continuously push the rake material from the edges towards the center, refining it and improving the mixing and dissolving efficiency.

[0064] Meanwhile, in order to further push the solid materials, the top of the airflow stirring pipe 32 is integrally formed with a downward bending pipe portion 32 which is arranged in a downward bending manner, and the bottom of the downward bending pipe portion 32 is provided with a plurality of airflow through holes. During the pumping process, the airflow through holes on the downward bending pipe portion 32 agitate the gas towards the central part of the hot stirring ingredient cylinder 1, so as to further improve the agitation effect on the solid materials and promote the fine dispersion of the solid materials by the rake frame portion.

[0065] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the skilled in the art within the essential scope of the present application shall also belong to the protection scope of the present application.
