[0034] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0036] Example 1

[0037] The utility model embodiment provides a segmented cooling disperser 100, such as Figures 1 to 8 As shown, the segmented cooling disperser 100 includes a dispersion barrel 1, a dispersion wheel 2 and a driving device (not shown).

[0038] The dispersion cylinder 1 has a dispersion chamber; the dispersion wheel 2 is disposed in the dispersion cylinder 1, and the driving device is connected to the dispersion wheel 2 via a rotating shaft 5 and drives the dispersion wheel 2 to rotate in the dispersion chamber. The dispersion cylinder 1 is used to pass the material to be dispersed, and the dispersion wheel 2 is driven by the driving device to rotate to disperse the material in the dispersion cylinder 1.

[0039] A first cooling channel 11 and a second cooling channel 12 are formed in the dispersion cylinder 1 . The first cooling channel 11 is located on the outside of the dispersion wheel 2 , and the second cooling channel 12 is located on the inside of the dispersion wheel 2 .

[0040] When it is necessary to mix and disperse materials such as powder and solvent to form a slurry, the materials such as powder and solvent are respectively introduced into the dispersion cylinder 1, and the driving device drives the dispersion wheel 2 to rotate. During the rotation of the dispersion wheel 2, a centrifugal effect is formed, and the powder and solvent are dispersed at high speed to form a slurry during the collision process. The first cooling channel 11 is formed on the outer side of the dispersion wheel 2, and the second cooling channel 12 is formed on the inner side of the dispersion wheel 2. The two cooling channels cooperate to form an outer cooling channel and an inner cooling channel, so that the material can be cooled when flowing on the outer side and the inner side of the dispersion wheel 2, which can effectively reduce the heat generated by the material during high-speed dispersion, and can achieve excellent cooling effect while ensuring high-speed dispersion.

[0041] In some embodiments, Figures 3 to 5As shown, the dispersion wheel 2 is at least partially a hollow annular sleeve structure, the first cooling channel 11 is located on the outside of the annular sleeve structure of the dispersion wheel 2, and the second cooling channel 12 is located on the inside of the annular sleeve structure of the dispersion wheel 2. The design of the hollow annular sleeve structure of the dispersion wheel 2 can form an airflow flowing inside and outside when the dispersion wheel 2 rotates, driving the material to collide well with the inner wall of the dispersion cylinder 1 and the inner wall and outer wall of the dispersion wheel 2 during the flow from the annular sleeve of the dispersion wheel 2 to be fully dispersed. The first cooling channel 11 is formed on the outside of the annular sleeve structure of the dispersion wheel 2, and the second cooling channel 12 is formed on the inside of the annular sleeve structure of the dispersion wheel 2. The two cooling channels cooperate to allow the material to be cooled when flowing on the outside and inside of the annular sleeve structure of the dispersion wheel 2, thereby improving the compactness of the structure, ensuring high-speed dispersion, and achieving excellent cooling effect.

[0042] In some embodiments, Figures 2 to 5 As shown, the dispersion cylinder 1 includes a cylinder body 13, the peripheral wall of the cylinder body 13 is an internal hollow structure forming the first cooling channel 11, and the side walls of the cylinder body 13 are respectively provided with a first inlet 131 and a first outlet 132 corresponding to the opposite ends of the first cooling channel 11; wherein a cooling medium such as a cooling fluid or a cooling gas is introduced into the first cooling channel 11 through the first inlet 131, and the cooling medium flows in the first cooling channel 11 and flows out from the first outlet 132, forming a circulating reciprocating flow, which can always ensure the cooling effect in the first cooling channel 11.

[0043] The dispersion tube 1 is provided with a cooling element 14, such as Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the cooling member 14 includes a support body 141 and a cooling jacket 142 disposed on the support body 141, the support body 141 is connected to the barrel 13, the support body 141 is annular, and the interiors of the support body 141 and the cooling jacket 142 are hollow to form the second cooling channel 12, the support body 141 is respectively provided with a second inlet 143 and a second outlet 144 at opposite ends corresponding to the second cooling channel 12, and the dispersion wheel 2 is located between the barrel 13 and the cooling jacket 142. A cooling medium such as a cooling fluid or a cooling gas is introduced into the second cooling channel 12 through the second inlet 143, and the cooling medium flows in the second cooling channel 12 and flows out from the second outlet 144, forming a cyclic reciprocating flow, which can always ensure the cooling effect in the second cooling channel 12. Specifically, the material introduced into the dispersion cylinder 1 flows through the position between the dispersion wheel 2 and the cylinder 13 during the rotation of the dispersion wheel 2, and flows through the cooling jacket 142 through the dispersion wheel 2, and finally flows out from the position between the inner ring edge of the support body 141 and the rotating shaft 5. It should be noted that the radial length of the inner ring of the support body 141 is greater than the radial length of the rotating shaft 5, so that a flow channel can be formed between the inner ring edge of the support body 141 and the rotating shaft 5, so that the dispersed material can flow out from the flow channel between the inner ring edge of the support body 141 and the rotating shaft 5. During the flow of the material in the above path, the material is externally cooled through the first cooling channel 11 located on the outer side of the dispersion wheel 2, and internally cooled through the second cooling channel 12 on the inner side of the dispersion wheel 2, thereby greatly increasing the cooling effect on the material and effectively reducing the heat generated by the material during the high-speed dispersion process.

[0044] In some embodiments, a temperature sensor (not shown) is provided at the first outlet 132 of the first cooling channel 11 and the second outlet 144 of the second cooling channel 12, and a switch valve (not shown) is provided at the first inlet 131 of the first cooling channel 11 and the second inlet 143 of the second cooling channel 12.

The fixed plate 21 is fixedly connected to the rotating shaft 5, and the driving device drives the fixed plate 21 and the dispersion plate 22 on the fixed plate 21 to rotate together through the rotating shaft 5. The dispersion plate 22 is arranged on the side of the fixed plate 21 away from the feeding direction. The material entering the dispersion cylinder 1 flows along the fixed plate 21 to the position between the dispersion plate 22 and the cylinder 13, and after being cooled by the first cooling channel 11 on the cylinder 13, it flows into the inner side of the dispersion plate 22 through the hollow structure on the dispersion plate 22, and after being cooled by the second cooling channel 12 of the cooling member 14, it finally flows out through the position between the inner ring edge of the support body 141 and the rotating shaft 5.

[0046] In some embodiments, Figure 3 As shown, the orientation direction of the dispersion plate 22 is opposite to that of the cooling jacket 142, the cooling jacket 142 is inserted in the ring position of the dispersion plate 22, and the cooling jacket 142 is a hollow structure. Specifically in this embodiment, the fixed plate 21 is a circular plate structure, and the dispersion plate 22 is vertically arranged on the side of the fixed plate 21 away from the feeding direction, wherein the fixed plate 21 is arranged parallel to the support body 141, and the orientation direction of the dispersion plate 22 is opposite to that of the cooling jacket 142, so that the cooling jacket 142 is inserted in the ring position of the dispersion plate 22. After being cooled by the first cooling channel 11 on the cylinder 13, it flows into the inner side of the dispersion plate 22 through the hollow structure on the dispersion plate 22, and after being cooled by the second cooling channel 12 of the cooling member 14, it flows to the position between the inner ring edge of the support body 141 and the rotating shaft 5 through the hollow structure of the cooling jacket 142, and finally flows out to the external collection device. In addition, a plug-in sleeve 23 is provided at the center position of the fixed plate 21, and the height of the plug-in sleeve 23 is consistent with the height of the dispersion plate 22. The plug-in sleeve 23 is used to fix the rotating shaft 5, so that the dispersion wheel 2 can be stably fixed on the rotating shaft 5 as a whole, wherein a convex column can be provided on the rotating shaft 5, and a card groove is opened on the inner wall of the plug-in sleeve 23. The plug-in sleeve 23 is firmly connected to the rotating shaft 5 through the card groove and the card groove. The relative sliding of the two is prevented from affecting the dispersion effect of the dispersion wheel 2 on the material.

[0047] In some embodiments, Figure 6As shown, the dispersion plates 22 are provided in plurality, and the radial lengths of the dispersion plates 22 increase successively. The cylinder 13 is located outside the outermost dispersion plate 22, and the cooling jacket 142 is located between two adjacent dispersion plates 22. The provision of a plurality of annular dispersion plates 22 can increase the flow path of the material, which can improve the cooling effect of the material on the one hand, and the dispersion effect of the material on the other hand.

[0048] In some embodiments, two dispersion plates 22 are provided, and the radial lengths of the two dispersion plates 22 are successively increased and form a concentric ring structure. The cooling jacket 142 is located between the two dispersion plates 22.

In the above structure, by forming a structure in which materials enter from the top and exit from the bottom, compared with the existing structure in which materials enter from the bottom and exit from the top, the structural setting of this embodiment will not repeatedly disperse the materials, improve the dispersion efficiency, facilitate the subsequent cleaning operation, and reduce the sealing requirements, thereby reducing the difficulty of assembling the equipment. And the driving device is arranged above the dispersion cylinder 1, which is more convenient for its assembly. Specifically, the dispersion cylinder 1 includes an upper end cover 18, which is tightly connected to the first-stage cylinder 13 through fasteners. The upper end cover 18, the two cylinders 13 and the two cooling members 14 cooperate to form a closed dispersion chamber structure of the dispersion cylinder 1, wherein the powder inlet 151 and the liquid inlet 152 are both arranged at the upper end cover 18.

Cooling medium is simultaneously introduced into the first cooling channel 11 and the second cooling channel 12. During the flow of the cooling medium, the materials on the inner and outer sides of the dispersion wheel 2 are cooled synchronously.
