[0002] In the preparation of ultrafine particles from nano-ceramic materials, the dried ceramic material dry colloid is usually crushed by rotating a cutting tool. However, due to the high overall hardness and brittleness of the nano-ceramic material dry colloid, a large amount of heat is generated when the material colloid colloids with the cutting tool. The cutting tool overheats significantly, making it difficult to carry out continuous crushing processing, thus affecting the preparation efficiency of ultrafine particles from nano-ceramic materials.

[0003] Specifically, a nano-ceramic material ultrafine particle preparation device with patent number CN220634600U has the following defects while solving the above problems: the rotation of the rotary crushing barrel alone cannot fully agitate the raw materials to crush them, and it also cannot cool down the rotary crushing barrel. Utility Model Content

[0004] The purpose of this invention is to provide a device for preparing nano-ceramic material particles.

[0005] The technical problem of this utility model is mainly solved by the following technical solution:

[0006] A device for preparing nano-ceramic material particles includes two sets of supports mounted on a base, on which a rotating crushing barrel driven by a driving device is mounted. The rotating crushing barrel has a feed inlet, and an impact column is disposed inside the rotating crushing barrel. Protrusions are uniformly arranged on the outer wall of the impact column and the inner wall of the rotating crushing barrel.

[0007] The rotating crushing barrel has a circular tube I and a circular tube II passing through the corresponding support at both ends. The impact column has a rotating shaft passing through the corresponding circular tube I and circular tube II at both ends.

The other set of L-shaped plates also has a cold air box that is attached to the end of the circular tube II. The impact column, the rotating crushing barrel and the circular tube II are also equipped with a cooling mechanism connected to the cold air box.

[0008] The cooling mechanism includes an air supply channel surrounding one end of the side wall of the circular tube II. An air inlet channel communicating with the air supply channel is axially arranged in the side wall of the circular tube II. A circular hole communicating with the air inlet channel is provided on one side wall of the cold air box. Several cooling channels I communicating with the air supply channel are arranged along the length of the side wall of the rotating crushing barrel. One end of the cooling channel I is connected to the internal opening of the circular tube I. A cooling channel II is provided on the rotating shaft inside the circular tube I, penetrating the impact column and extending to the outside of another set of rotating shafts. The cooling channel II inside the impact column is spirally arranged. A ring groove corresponding to the end of the cooling channel I is also arranged around the rotating shaft inside the circular tube I. A through hole communicating with the cooling channel II is provided on the ring groove.

[0009] Preferably, the transmission mechanism includes an annular seat disposed at the end of the circular tube I, an internal gear ring disposed on one side of the annular seat, an external gear ring disposed at the end of the rotating shaft located in the opening of the internal gear ring, a gear disposed between the internal gear ring and the external gear ring and meshing with both, the gear being fixed to a corresponding L-shaped plate by a fixed shaft, and a bearing I for fixing the fixed shaft being disposed on the L-shaped plate.

[0014] The beneficial effects of this utility model are as follows: This utility model drives the impact column and the rotary crushing barrel to rotate in different directions simultaneously through the driving device. The rotary crushing barrel drives the material inside to rotate, so that the material can fully collide with the impact column and the different end faces of the rotary crushing barrel, thereby improving its crushing effect and efficiency. At the same time, when the rotary crushing barrel is rotating, cooling air is injected into the cooling mechanism of the rotary crushing barrel.

Shell. Detailed Implementation

[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] A device for preparing nano-ceramic material particles includes two sets of supports 2 mounted on a base 1. A rotating crushing barrel 3, driven by a driving device 4, is mounted on each set of supports 2. The rotating crushing barrel 3 has a feed inlet 5, and an impact column 6 is disposed inside the rotating crushing barrel 3. Protrusions 7 are uniformly arranged on the outer wall of the impact column 6 and the inner wall of the rotating crushing barrel 3.

[0023] The rotating crushing barrel 3 is provided with a circular tube I8 and a circular tube II9 passing through the corresponding support 2 at both ends. The impact column 6 is provided with a rotating shaft 10 passing through the corresponding circular tube I8 and the circular tube II9 at both ends. The support 2 is provided with an L-shaped plate 11 for fixing the end of the corresponding rotating shaft 10. One set of L-shaped plates 11 is provided with a transmission mechanism 12 connecting the circular tube I8 and the corresponding rotating shaft 10, and another set of L-shaped plates 11 is also provided with a cold air box 13 that is attached to the end of the circular tube II9. The impact column 6, the rotating crushing barrel 3 and the circular tube II9 are also provided with a cooling mechanism 14 connected to the cold air box 13.

[0024] The cooling mechanism 14 includes an air supply channel 141 surrounding one end of the side wall of the circular tube II9. An air inlet channel 142 communicating with the air supply channel 141 is axially arranged in the side wall of the circular tube II9. A circular hole 143 communicating with the air inlet channel 142 is provided on one side wall of the cold air box 13. Several cooling channels I144 communicating with the air supply channel 141 are arranged along the length of the side wall of the rotating crushing barrel 3. One end of the cooling channel I144 is connected to the internal opening of the circular tube I8. A cooling channel II145 is provided on the rotating shaft 10 inside the circular tube I8, penetrating the impact column 6 and extending to the outside of another set of rotating shafts 10. The cooling channel II145 inside the impact column 6 is spirally arranged. A ring groove 146 corresponding to the end of the cooling channel II145 is also arranged around the rotating shaft 10 inside the circular tube I8. A through hole 147 communicating with the cooling channel II145 is provided on the ring groove 146.

[0025] The transmission mechanism 12 includes an annular seat 121 disposed at the end of the circular tube I8. An internal gear ring 122 is disposed on one side of the annular seat 121. An external gear ring 123 is disposed at the end of the rotating shaft 10, located inside the opening of the internal gear ring 122. A gear 124 is disposed between the internal gear ring 122 and the external gear ring 123, meshing with both. The gear 124 is fixed on the corresponding L-shaped plate 11 by a fixed shaft 125. A bearing I for fixing the fixed shaft 125 is disposed on the L-shaped plate 11.

[0026] In this embodiment, the rotating shaft 10 is adapted to the internal opening size of the corresponding round tube I8 and round tube II9. The bracket 2 is provided with bearing II for fixing the corresponding round tube I8 and round tube II9, and the L-shaped plate 11 is provided with bearing III for fixing the rotating shaft 10.

[0027] The driving device 4 includes a motor 41, and the output shaft of the motor 41 and the circular tube II9 are respectively provided with pulleys, wherein the two sets of pulleys are connected by a transmission belt 42.

[0028] like Figure 2 , 4As shown, one end of the rotating shaft 10 passes through the circular hole 147 and the corresponding side wall of the cold air box 13 in sequence. The inner diameter of the circular hole 147 is larger than the diameter of the rotating shaft 10, and the inner diameter of the circular hole 147 is smaller than the diameter of the circular tube II9.

[0029] In this embodiment, the protrusion 7 is in the shape of a triangular pyramid. The protrusion 7 is covered with a metal shell 15 that is adapted to it. An elastic element is provided on the outer wall of the protrusion 7, which is connected to the inner wall of the shell 15 and suspends it. The bottom of the shell 15 is connected to the outer wall of the corresponding impact column 6 and the inner wall of the rotating crushing barrel 3 through an elastic band.

[0030] The method of using this utility model is as follows: The raw material is introduced into the rotary crushing barrel 3. The motor 41 drives the round tube II9 and round tube I8 to rotate on the L-shaped plate 11 through the transmission belt 42, thereby driving the rotary crushing barrel 3 to rotate. At the same time, the rotating round tube I8 drives the rotating shaft 10 and the impact column 6 to rotate through the annular seat 121, the internal gear ring 122, the gear 124 and the external gear ring 123. At this time, the rotation direction of the impact column 6 is opposite to that of the rotary crushing barrel 3. During this process, the driving device simultaneously drives the impact column 6 and the rotary crushing barrel 3 to rotate in different directions. The rotary crushing barrel 3 drives the material inside to rotate, so that the material fully collides with the impact column 6 and the different end faces of the rotary crushing barrel 3. When the material hits the impact column 6 and the protrusion 7, the material can break due to its brittleness. The broken material will rebound to the inner wall of the rotary crushing barrel 3. The material can reciprocate between the rotary crushing barrel 3 and the impact column 6 as it rotates, thereby breaking the material into fine particles.

[0031] During the above process, the material repeatedly bounces in the rotary crushing barrel 3 under the influence of rotational force, frequently comes into contact with and collides with the protrusions 7 on the inner wall of the rotary crushing barrel 3 and the outer wall of the impact column 6, thereby squeezing the shell 15 and compressing the elastic element. When the elastic element stretches out, the rebound force generated can exert a large rebound force on the raw material in contact with it through the shell 15, so that the raw material can fully reciprocate between the rotary crushing barrel 3 and the impact column 6.

[0032] Simultaneously, cold gas is injected into the cold air box 13. At this time, the circular tube II9 rotates under the influence of the driving device, and the air inlet channel 142 on the rotating circular tube II9 is ​​always connected to the circular hole 143. Then, the cold air in the cold air box 13 can enter the air supply channel 141 through the air inlet channel 142, and then flow through several cooling channels I144 on the outer wall of the rotating crushing barrel 3 to cool its side wall. At the same time, this part of the gas is also recovered and enters the annular groove 146 from the outlet end of the cooling channel I144, and then enters the cooling channel II145 through the annular groove 146 and the through hole 147 to cool the side wall. The impact column 6 is cooled and then discharged. During the above process, when the rotating shaft 10 rotates, it will drive the annular groove 146 to rotate. However, the annular groove 146 is always connected to the cooling channel I144, so that it can continuously introduce cold air into the annular groove 146 and flow into the cooling channel II145 through the through hole 147. This utility model can introduce cold air into the rotating crushing barrel 3 and the impact column 6 during the process of the equipment rotating to process materials, and then cool them down in sequence, thereby making full use of the cold air in the cold gas to cool down the above equipment and preventing energy waste.

All equivalent changes and improvements made in accordance with the claims of the present invention should still fall within the patent coverage of the present invention.
