AI Technical Summary
In existing sand mills, the raw material particles in the dispersion tank are difficult to separate evenly, resulting in a large error between the proportion of each component in the powder produced by sand milling and the target. This can easily lead to clogging of the sand mill and increase cleaning and maintenance costs.
Design a dispersion tank comprising a filter screen dividing it into a dispersion chamber and a filtration chamber. Equipped with a stirring and pulverizing mechanism, the raw materials are uniformly mixed by stirring blades, and particles that are difficult to pass through the filter screen are pulverized by high-speed rotating blades, allowing them to uniformly enter the filtration chamber and finally enter the sand mill.
It achieves uniform mixing and crushing of raw materials, ensuring that all particles enter the sand mill, reducing the risk of sand mill blockage, reducing cleaning and maintenance costs, and improving production efficiency.

[0045] Please refer to Figure 1 With Figure 2 , Figure 2A structure diagram of a dispersion tank in an embodiment of the present application is shown. The dispersion tank 1100 provided in an embodiment of the present application comprises a tank body 1110, a filter screen 1120, a stirring mechanism 1130, and a crushing mechanism 1140. The tank body 1110 comprises a receiving cavity 1115, a feeding port 1116, and a discharging port 1117. The filter screen 1120 is located in the receiving cavity 1115. The filter screen 1120 divides the receiving cavity 1115 into a dispersion sub-cavity 1115-1 and a filtering sub-cavity 1115-2, which are arranged along the gravity direction of the tank body 1110 and are in communication with each other. The dispersion sub-cavity 1115-1 is in communication with the feeding port 1116, and the filtering sub-cavity 1115-2 is in communication with the discharging port 1117. The stirring mechanism 1130 comprises a stirring blade 1133, which is located in the dispersion sub-cavity 1115-1 and is rotationally connected with the tank body 1110. The crushing mechanism 1140 comprises a plurality of blades 1142 located in the dispersion sub-cavity 1115-1. The plurality of blades 1142 are distributed around the central axis of the filter screen 1120. The blades 1142 are located between the stirring blade 1133 and the filter screen 1120 and are rotationally connected with the tank body 1110. The blades 1142 are provided with cutting edges (not shown). The central axis of the filter screen 1120 is parallel to the gravity direction of the tank body 1110.
[0046] In the embodiment, the worker adds various raw materials into the dispersion sub-cavity 1115-1 through the feeding port 1116. The various raw materials entering the dispersion sub-cavity 1115-1 are stirred uniformly and mixed fully in the process of the stirring blade 1133 rotating relative to the tank body 1110, and the fully mixed raw materials form a sanding material to be ground. The particles with smaller diameters in the sanding material to be ground pass through the filter screen 1120, enter the filtering sub-cavity 1115-2 from the dispersion sub-cavity 1115-1, and leave the filtering sub-cavity 1115-2 from the discharging port 1117. In this process, the worker puts the sanding material to be ground discharged from the tank body 1110 through the discharging port 1117 into the sanding machine 1200 for sanding to prepare a powder-like sanding material. Since the sanding material to be ground in the sanding machine 1200 has small diameters, the sanding machine 1200 can be prevented from being blocked, the cost of the worker for disassembling and cleaning the sanding machine 1200 is reduced, and the production efficiency is improved.
[0047] In addition, in order to ensure that all the materials to be sanded can be sanded by the sanding machine 1200, the staff drives the blades 1142 to rotate relative to the tank body 1110, so that the cutting edges provided on the blades 1142 rotate at high speed, and the cutting edges rotate at high speed to crush the part of the material to be sanded in the dispersion sub-cavity 1115-1 that is difficult to pass through the filter screen 1120, until all the part of the material to be sanded in the dispersion sub-cavity 1115-1 that is difficult to pass through the filter screen 1120 is crushed into particles with a diameter smaller than the filter holes (not labeled in the figure) of the filter screen 1120. When all the part of the material to be sanded in the dispersion sub-cavity 1115-1 is crushed into particles with a diameter smaller than the filter holes of the filter screen 1120, all the part of the material to be sanded in the dispersion sub-cavity 1115-1 passes through the filter screen 1120, enters the filtration sub-cavity 1115-2, and exits the filtration sub-cavity 1115-2 from the discharge port 1117, and is finally put into the sanding machine 1200 by the staff for sanding. In summary, the dispersion tank 1100 in the present example, by providing the crushing mechanism 1140, ensures that after the raw materials added into the tank body 1110 are uniformly mixed, they are all crushed into particles with a smaller diameter by the crushing mechanism 1140, thereby ensuring that all the raw material mixture in the tank body 1110 can be put into the sanding machine 1200 by the staff for sanding, and reducing the error between the actual proportion of each component in the powder sanded by the sanding machine 1200 and the target value.

The tank top 1111, the tank body 1112 and the tank bottom 1113 together form a containing cavity 1115, and the inner diameter of the tank bottom 1113 gradually decreases in the direction away from the tank top 1111. The filter screen 1120 and the tank bottom 1113 together form a filtration sub-cavity 1115-2. The crushing mechanism 1140 includes a plurality of first driving members 1141, which are arranged around the outer periphery of the filter screen 1120. The fixed end of the first driving member 1141 is connected to the tank bottom 1113, and the movable end of the first driving member 1141 is connected to at least one blade 1142. The first driving member 1141 is configured to drive the corresponding blade 1142 to rotate.
[0049] In the embodiment, since the plurality of blades 1142 are distributed around the central axis of the filter screen 1120, the portions of the abrasive materials that are difficult to pass through the filter screen 1120 in the dispersion sub-cavity 1115-1 can be crushed by the blades 1142. During the crushing process, each first driving member 1141 drives the corresponding blade 1142 to rotate at a high speed, and the blade rotating at a high speed crushes the portions of the abrasive materials that are difficult to pass through the filter screen 1120 in the dispersion sub-cavity 1115-1 until the plurality of blades 1142 crush all the portions of the abrasive materials that are difficult to pass through the filter screen 1120 in the dispersion sub-cavity 1115-1 into particles with a diameter less than the filter holes of the filter screen 1120.
[0050] It should be noted that the staff can select the filter screen 1120 with different filter hole diameters according to the actual sanding capacity of the sanding machine 1200.
[0051] In some embodiments, the tank body 1110 includes a plurality of support columns 1114 arranged around the central axis of the tank bottom 1113 and away from the tank body 1112.

[0053] In the embodiment, the filter screen 1120 includes a disc provided with a plurality of filter holes, and the ratio of the diameter of the disc to the maximum inner diameter of the tank bottom 1113 is less than or equal to 1 / 4, so that more portions of the tank bottom 1113 are located in the dispersion sub-cavity 1115-1, the space available for installing the first driving member 1141 on the portions of the tank bottom 1113 in the dispersion sub-cavity 1115-1 is increased, and the staff can conveniently install the crushing mechanism 1140 in the dispersion sub-cavity 1115-1.
[0054] In some embodiments, the central axis of the tank top 1111, the central axis of the tank body 1112, and the central axis of the tank bottom 1113 all coincide with the central axis of the tank body 1110.
[0055] Please refer to Figure 2In some embodiments, the stirring mechanism 1130 includes a stirring shaft 1132 and a second driving member 1131, the stirring shaft 1132 extends along the gravity direction of the tank body 1110, is located in the dispersion sub-cavity 1115-1, and is arranged on the side of the blade 1142 away from the filter screen 1120, the stirring shaft 1132 is provided with at least one stirring blade 1133, and the end of the stirring shaft 1132 away from the filter screen 1120 is arranged in the tank top 1111 and connected with the second driving member 1131 arranged in the tank top 1111, and the second driving member 1131 is configured to drive the stirring shaft 1132 to rotate around the axis thereof.
[0056] In the embodiment, when the worker adds various raw materials into the dispersion sub-cavity 1115-1 through the feeding port 1116, the second driving member 1131 drives the stirring shaft 1132 to rotate around the axis thereof, the stirring shaft 1132 drives the stirring blade 1133 to rotate relative to the tank body 1110, the moving stirring blade 1133 stirs the various raw materials entering the dispersion sub-cavity 1115-1 until the raw materials are uniformly stirred and fully mixed, and the second driving member 1131 stops driving.
[0057] Please continue to refer to Figure 2 The stirring shaft 1132 is provided with a plurality of stirring blades 1133, and the plurality of stirring blades 1133 are arranged along the central axis of the stirring shaft 1132.
[0058] In the embodiment, the plurality of stirring blades 1133 are arranged along the central axis of the stirring shaft 1132, so that the material in each layer of the raw material mixture in the dispersion sub-cavity 1115-1 can be stirred in the direction of the central axis of the stirring shaft 1132, and the raw material mixture in the dispersion sub-cavity 1115-1 is uniformly stirred and fully mixed.
[0059] Please refer to Figure 1 and Figure 4 , Figure 1 The structure of the sand mill device in the embodiment is shown, and the sand mill device 1000 provided by the embodiment includes the dispersion tank 1100 and the sand mill 1200, the dispersion tank 1100 is provided with a return port 1118 at one end along the gravity direction thereof, the return port 1118 is in communication with the dispersion sub-cavity 1115-1, the inlet of the sand mill 1200 is in communication with the discharge port 1117 of the dispersion tank 1100, and the outlet of the sand mill 1200 is in communication with the return port 1118.
[0060] In this embodiment, the worker adds various raw materials into the dispersion sub-cavity 1115-1 through the feeding port 1116. The various raw materials entering the dispersion cavity 1115-1 are stirred uniformly and mixed fully in the process of the stirring blade 1133 rotating relative to the tank body 1110. The mixed raw materials form a sanding material to be ground. The particles with smaller diameters in the sanding material to be ground pass through the filter screen 1120, enter the filtering sub-cavity 1115-2 from the dispersion sub-cavity 1115-1, and exit the filtering sub-cavity 1115-2 from the discharge port 1117. The part of the sanding material to be ground that exits the tank body 1110 from the discharge port 1117 enters the sanding machine 1200 through the inlet of the sanding machine 1200 and is ground into a powder by the sanding machine 1200. Since the particles of the part of the sanding material to be ground that is ground by the sanding machine 1200 all have smaller diameters, the sanding machine 1200 can be prevented from being blocked, the cost of the worker disassembling and cleaning the sanding machine 1200 is reduced, and the production efficiency is improved.
[0061] In addition, in order to ensure that all the sanding material to be ground can be ground by the sanding machine 1200, the worker drives the blade 1142 to rotate relative to the tank body 1110, so that the cutting edge provided on the blade 1142 rotates at a high speed. The part of the sanding material to be ground that is difficult to pass through the filter screen 1120 in the dispersion sub-cavity 1115-1 is crushed by the cutting edge rotating at a high speed until all the part of the sanding material to be ground that is difficult to pass through the filter screen 1120 in the dispersion sub-cavity 1115-1 is crushed into particles with diameters smaller than the filter holes of the filter screen 1120. When all the sanding material to be ground in the dispersion sub-cavity 1115-1 is crushed into particles with diameters smaller than the filter holes of the filter screen 1120, all the sanding material to be ground in the dispersion sub-cavity 1115-1 passes through the filter screen 1120, enters the filtering sub-cavity 1115-2, exits the filtering sub-cavity 1115-2 from the discharge port 1117, and finally enters the sanding machine 1200 to be ground. As described above, the sanding device 1000 in this example is provided with the crushing mechanism 1140. After the various raw materials added into the tank body 1110 are mixed uniformly, the crushing mechanism 1140 crushes the raw materials into particles with smaller diameters. Thus, it is ensured that all the mixture of the raw materials in the tank body 1110 can enter the sanding machine 1200 to be ground, and the error between the actual proportion of each component in the powder ground by the sanding machine 1200 and the target value is reduced.
[0062] Please refer to Figure 1 and Figure 4 In some embodiments, the sanding device 1000 includes a first suction pump 1300. The liquid inlet end of the first suction pump 1300 is in communication with the discharge port 1117, and the liquid outlet end of the first suction pump 1300 is in communication with the inlet of the sanding machine 1200.
[0063] In this embodiment, the smaller diameter particles in the sanding material in the dispersion sub-cavity 1115-1 pass through the filter screen 1120 from the dispersion sub-cavity 1115-1 into the filtration sub-cavity 1115-2. The portion of the sanding material in the filtration sub-cavity 1115-2 is first removed from the tank 1110 through the discharge port 1117 under the suction force of the first suction pump 1300, then enters the first suction pump 1300 through the liquid inlet of the first suction pump 1300, and finally exits the first suction pump 1300 through the liquid outlet of the first suction pump 1300 and enters the sanding machine 1200 through the inlet of the sanding machine 1200 to be sanded.
