[0009] Furthermore, the separation cover is of hemispherical design, and a plurality of secondary separation holes are provided on the spherical outer wall of the separation cover, and the secondary separation holes allow standard materials to enter. The end of the flow gap is designed at the separation cover near the end cover of the assembly cylinder, and the inner wall at the end of the flow gap is provided with a return port connected to the grinding chamber, and the grinding medium is allowed to pass through.

[0010] Furthermore, the assembly shaft and the separation cover are integrally formed, and the interior of the assembly shaft and the separation cover is hollow, the hollow design is located in the discharge channel, and a narrow mouth is also designed between the separation cover and the assembly shaft.

[0011] Furthermore, a first isolation ring is fixedly installed at the end of the separation cylinder in the grinding chamber, and a second isolation ring is slidably installed in the grinding chamber. When the second isolation ring slides to a preset position, it can be combined with the first isolation ring to block the connection between the grinding chamber and the outside. The second isolation ring is controlled by a linear drive installed on the outside of the assembly cylinder.

[0012] Furthermore, an assembly ring is designed at the end of the assembly shaft, and an axial flow fan blade is fixedly installed on the inner wall of the assembly ring located in the discharge channel. The axial flow fan blade and the assembly shaft share a common rotation axis L.

The interior of the hollow main shaft is connected to the interior of the assembly ring, and the axial flow fan blade can transfer the material in the assembly shaft to the interior of the hollow main shaft when it rotates.

[0013] Furthermore, a rod pin portion is rotatably installed in the assembly cylinder, the interior of the rod pin portion is hollowed out, and the hollow main shaft passes through the rod pin portion and is fixedly connected to the end of the assembly ring.

[0019] Second, by changing the size of the flow gap and cooperating with the equal dragon blades, the slurry entering the flow gap can be forced to flow by the equal dragon blades, so that the slurry can exert pressure on the separation cover to complete the separation between the grinding medium and the material. At the same time, by giving the slurry flow pressure, it will not cause blockage in the process of passing through the secondary separation hole. The fluid pressure will break through the material aggregates that show signs of blockage, which can not only improve the separation efficiency and quality, but also prevent blockage.

[0020] 3. By designing the discharge channel, when the material enters the separation cover through the secondary separation hole, it will be transferred to the inside of the assembly shaft. Due to the rotation of the assembly shaft, the material can be prevented from settling or staying still in the discharge channel. When the external pump body collects the material, the dispersion of the material can be ensured.

[0021] Fourth, by designing axial flow blades inside the assembly ring, when the assembly shaft rotates along the rotation axis L, the axial flow blades will rotate. The rotation of the axial flow blades can generate outward conveying pressure in the discharge channel, thereby effectively attracting the finished material to enter.

[0022] 5. By configuring the necking design, the slurry delivery pressure can be maximized. The necking can once again increase the pressure exerted by the slurry on the separation cover, thereby improving the separation quality and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 5 The present invention provides a technical solution: a nano-grinder separation structure, comprising:

[0031] An assembly cylinder 2 and a grinding chamber inside thereof; a separation cylinder 5 fixedly designed in the grinding chamber, the separation cylinder 5 being designed with a plurality of primary separation holes, the separation cylinder 5 being designed with an assembly shaft 7 for internal rotation, a flow gap being provided between the assembly shaft 7 and the separation cylinder 5; a separation cover 12 assembled inside the separation cylinder 5; a discharge channel connected to the flow gap by the separation cover 12, the discharge channel being designed inside the assembly shaft 7; an actuating structure for applying flow pressure to the slurry inside the flow gap, the flow direction of the slurry after being pressurized is from the flow gap to the separation cover 12 and then to the discharge channel; the flow end of the flow gap is connected to the grinding chamber.

[0032] In the prior art, the screen or the gap may be blocked by the filling of the material, or blocked by the consumed or damaged grinding medium. Under the influence of the viscosity and adsorption of the material, the gap and the screen may be partially blocked, affecting the grinding quality and efficiency, and the blocked position will gradually expand, resulting in the unusable filter or gap. In the present invention, the flow gap and the primary separation hole are first designed, so that the material in the grinding chamber can enter the flow gap through the primary separation hole and flow to the separation cover 12 for further separation. In the process of secondary separation, pressure is applied to the slurry through the actuating structure, so that the flow rate or pressure of the slurry can be increased, thereby improving the efficiency and quality of the secondary separation.

[0033] Secondly, the separation efficiency and quality of the materials can be improved through the hierarchical separation of the separation cylinder 5 and the separation cover 12.

[0034] In this embodiment, the separation cylinder 5 and the assembly cylinder 2 are designed as an integral whole, and the flow gap serves as a channel for conveying the slurry. Both ends of the channel are restricted by the separation cylinder 5 and the separation cover 12, so that the quality of the material finally entering the separation cover 12 is excellent, and the communication between the flow gap and the grinding chamber can allow the grinding medium to flow back to the grinding chamber under the action of slurry flow and centrifugation.

[0035] In a preferred embodiment, the actuating structure includes an equal dragon blade integrally formed on the outer wall of the assembly shaft 7, the flow gap between the equal dragon blade and the inner wall of the separation cylinder 5 is gradually reduced, and the first-stage separation hole is opened at the conveying starting end of the equal dragon blade, and the first-stage separation hole allows the grinding medium to enter, please refer to Figure 2 and Figure 3 In the prior art, such as the PHNSuperMaxZeta rod-pin nano sand mill, it only relies on the feed pressure of the feed pump to force the slurry to contact the screen or gap to complete the separation. However, since most grinding cylinders are horizontal, the feed pressure cannot stably and efficiently drive the slurry to complete the separation. The pressure of the slurry feed will be quickly dispersed when entering the grinding chamber, resulting in the slurry being unable to efficiently perform separation work under the reduced pressure. In this embodiment, by designing the size change of the flow gap and the coordination of the equal dragon blades, the slurry entering the flow gap can be forced to flow by the equal dragon blades, so that the slurry can apply pressure to the separation cover 12 to complete the separation between the grinding medium and the material. At the same time, by giving the slurry a flow pressure, it will not cause blockage in the process of passing through the secondary separation hole, and the fluid pressure will break through the material aggregates with signs of blockage, which can not only improve the separation efficiency and quality, but also prevent blockage.

[0036] Based on the actuation structure embodiment, a two-stage separation embodiment is provided. The separation cover 12 is a hemispherical design. A plurality of two-stage separation holes are provided on the spherical outer wall of the separation cover 12. The two-stage separation holes allow the entry of standard materials. The end of the flow gap is designed at the separation cover 12 near the end cover of the assembly cylinder 2. The inner wall at the end of the flow gap is provided with a return port connected to the grinding chamber. The grinding medium is allowed to pass through. Please refer to Figures 1 to 5 In this embodiment, the specific situation of the secondary separation is: the slurry enters the flow gap through the primary separation hole, and is given flow pressure in the flow gap, so that it can act on the secondary separation hole, and the liquid carrier and material in the slurry will enter the discharge channel through the secondary separation hole, while the grinding medium will be blocked by the secondary separation hole and flow back to the grinding chamber with the slurry.

[0037] The spherical outer wall of the separation cover 12 can mitigate the impact of the grinding medium on it.

[0038] On the basis of the two-stage separation embodiment, the assembly shaft 7 and the separation cover 12 are integrally formed, and the interior of the assembly shaft 7 and the separation cover 12 is a hollow design, the hollow design is located in the discharge channel, and a narrow mouth portion 13 is also designed between the separation cover 12 and the assembly shaft 7, see Figure 1 and Figure 2In this embodiment, the integral molding of the assembly shaft 7 and the separation cover 12 is a requirement for the integrity of the discharge channel. When the material enters the separation cover 12 through the secondary separation hole, it will be transferred to the inside of the assembly shaft 7. Due to the rotation of the assembly shaft 7, the material can be prevented from settling or remaining stationary in the discharge channel. When the external pump body collects the material, the dispersion of the material can be ensured.

[0039] On the basis of the two-stage separation embodiment, a first isolating ring 6 is fixedly installed at the end of the separation cylinder 5 in the grinding chamber, and a second isolating ring 11 is slidably installed in the grinding chamber. When the second isolating ring 11 slides to a preset position, it can be combined with the first isolating ring 6 and block the connection between the grinding chamber and the outside. The second isolating ring 11 is controlled by a linear drive installed outside the assembly cylinder 2, please refer to Figure 1 and Figure 2 In this embodiment, when material blockage, obstruction or other emergency situations occur, the grinding chamber can be sealed by the second isolation ring 11, and a sealed chamber will be formed between the second isolation ring 11, the first isolation ring 6, the assembly shaft 7 and the assembly cylinder 2, stopping the external slurry from continuing to be transported into the chamber. At the same time, the chamber wraps the separation cylinder 5 and the separation cover 12. At this time, the finished material in the discharge channel is extracted by the external pump body, so that the slurry in the sealed chamber will run to the flow gap and the discharge channel, thereby forcing the subsequent separation process to be completed.

[0040] On the basis of the secondary separation embodiment, an assembly ring 4 is designed at the end of the assembly shaft 7, and an axial flow fan blade 8 is fixedly installed on the inner wall of the assembly ring 4 located in the discharge channel. The axial flow fan blade 8 and the assembly shaft 7 share the rotation axis L. The end of the assembly ring 4 is fixedly connected to a hollow main shaft 1, and the hollow main shaft 1 is controlled to rotate by an external drive motor. The interior of the hollow main shaft 1 is connected to the interior of the assembly ring 4. When the axial flow fan blade 8 rotates, the material in the assembly shaft 7 can be transferred to the interior of the hollow main shaft 1. Please refer to Figure 1 to Figure 2 By designing axial flow blades 8 inside the assembly ring 4, when the assembly shaft 7 rotates along the rotation axis L, the axial flow blades 8 will rotate. The rotation of the axial flow blades 8 can generate outward conveying pressure in the discharge channel, thereby effectively attracting the finished material to enter.

[0041] Furthermore, a rod pin portion 3 is rotatably installed in the assembly cylinder 2 , the interior of the rod pin portion 3 is hollowed out, and the hollow main shaft 1 passes through the rod pin portion 3 and is fixedly connected to the end of the assembly ring 4 .

[0042] On the basis of the two-stage separation embodiment, the outer wall of the separation cover 12 and the inner wall of the separation cylinder 5 are designed with a constriction, and the constriction design is changed from large to small in the direction from the assembly axis 7 to the end cover of the assembly cylinder 2. Please refer to Figure 1As shown in the enlarged view of its details, the conveying pressure of the slurry can be maximized by configuring the necking design. The necking can once again increase the pressure applied by the slurry to the separation cover 12, thereby improving the separation quality and efficiency. Secondly, the necking design will not interfere with the backflow of the grinding medium.

[0043] The surface of the primary separation hole is covered with a filter screen.

[0044] Furthermore, a pressure monitor and a flow rate monitor are installed in the discharge channel, and the pressure monitor and the flow rate monitor are associated with an external pan-tilt head, which controls the rotation of the assembly shaft 7.

[0045] By utilizing the above structures, flow pressure can be applied to the slurry, thereby improving the separation quality and efficiency of the grinding media and the material.

[0046] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
