[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-6 As shown, this utility model provides a technical solution: a high-flow-rate nano-sand mill, including a mill body 1, a cooling chamber 2 and a grinding chamber 3 are respectively arranged inside the mill body 1. The cooling chamber 2 is equipped with a water inlet 4 and a water outlet 5 (the water after absorbing heat is discharged through the water outlet 5). The grinding chamber 3 is equipped with a feed inlet 6 and a discharge outlet 7. A thermometer 8 is installed on the feed inlet 6, and the temperature inside the grinding chamber 3 can be monitored by the thermometer 8.

[0028] Multiple cooling pipes 9 are installed on the inner wall of the grinding chamber 3. Each cooling pipe 9 is connected to the cooling chamber 2. The cooling pipes 9 are made of ceramic material. On the one hand, ceramic material has good thermal conductivity. On the other hand, ceramic material has high hardness and is impact resistant. The cooling pipes 9 not only increase the cooling area, but also extend the depth of cooling penetration.

[0029] The grinding chamber 3 is equipped with a rotatable pin 10. The pin 10 is hollow and has a labyrinth-shaped baffle 102 inside (which increases the contact time between cooling water and material). Both ends of the pin 10 are equipped with rods 101. One end of the rod 101 extends out of the mill cylinder 1 and is equipped with a rotary joint 11. One end of the rotary joint 11 is equipped with a water inlet pipe 12. The water inlet pipe 12 is connected to a water pump, which delivers water to the water inlet pipe 12.

[0030] A drive motor 13 is installed on the side of the sand mill cylinder 1. Pulleys 14 are installed on the rod 101 on one side and at the output end of the drive motor 13. A belt 15 is connected between the pulleys 14.

[0031] The side of the mill cylinder 1 has a rotatable lead screw 16. The two ends of the lead screw 16 have opposite threads. The lead screw 16 is driven by an external motor 17. Two opposing sliding clamping wheels 18 are threadedly installed on the lead screw 16. The two clamping wheels 18 can clamp the belt 15 from both sides.

[0032] A filter cylinder 19 is installed on one side of the grinding chamber 3 near the discharge port 7.

[0033] The rod 101 portion located inside the filter cartridge 19 is equipped with a cleaning brush 24 for cleaning the inner wall of the filter cartridge 19.

[0034] The filter cylinder 19 has a U-shaped slot 20. A circular baffle 21 is installed on the rod 101. The rod 101 is eccentrically positioned in the slot 20. The through slots at both ends of the slot 20 are small circles, which are mainly for the rod 101 to pass through. The diameter of the through slots is larger than the outer diameter of the rod 101, which allows the filter cylinder 19 to move relative to the rod 101. The middle section of the slot 20 is a large circle, and the baffle 21 is located in the large circle. The diameter of the large circle is larger than the total length of the two baffles 21 and the rod 101, which allows the filter cylinder 19 to move relative to the baffles 21. It should be noted that no matter how the filter cylinder 19 moves, the baffle 21 can always completely cover the small circles, thereby preventing materials from directly entering the interior of the filter cylinder 19 from the slot 20.

[0035] A circular limiting plate 23 is installed on the rod 101 to limit the filter cylinder 19. The limiting plate 23 can limit the filter cylinder 19 in the horizontal direction, and the diameter of the limiting plate 23 is larger than the diameter of the small circle. The part of the rod 101 located inside the filter cylinder 19 is equipped with a striking hammer 22 that can strike the top of the inner wall of the filter cylinder 19.

[0036] When the rod 101 rotates, it will synchronously drive the striking hammer 22 to rotate (in the stationary state, the top of the blocking plate 21 is in contact with the top of the large circle, and the bottom of the blocking plate 21 is suspended in the air, such as...). Figure 5 As shown, when the hammer 22 rotates to the top, it will contact the inner wall of the filter cylinder 19 and further drive the filter cylinder 19 to vibrate upward, thereby shaking off the material adsorbed in the screen holes of the filter cylinder 19 and solving the material blockage problem.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During use, a portion of the cooling water is delivered to the cooling chamber 2 through the inlet 4 and can enter the cooling pipes 9 at deeper locations. This not only increases the contact area between the cooling water and the material but also extends the depth range of the cooling water, which is beneficial for cooling.

[0039] Another portion of the water enters the rod body 101 through the water inlet pipe 12 and the rotary joint 11, and finally enters the interior of the rod pin 10, thereby achieving the purpose of radiating cooling of the material from the central area to the outside.

[0040] Regarding the loose belt 15, the motor 17 is started, which drives the lead screw 16 to rotate, thereby causing the two sets of tensioning wheels 18 to move closer together and press the loose belt 15 inward until the belt 15 regains its tension. After that, the belt 15 can operate normally, thus extending the service life of the belt 15.

[0041] After the material enters the grinding chamber 3 through the feed inlet 6, the drive motor 13 is turned on, which drives the pin 10 to rotate, thereby causing the medium in the grinding chamber 3 to fully collide with the material, so as to achieve the purpose of nano-level pulverization of the material.

[0042] The crushed qualified material enters the filter cylinder 19 and is finally discharged through the discharge port 7. In response to the problem of clogging of the screen holes of the filter cylinder 19, when the rod 101 rotates, it will drive the cleaning brush 24 to clean the inner wall of the filter cylinder 19, thereby scraping off the material adsorbed in the screen holes and achieving the purpose of unclogging the screen holes.

[0043] In summary, this high-flow-rate nano-sand mill, through its dual internal and external cooling system, significantly improves cooling efficiency. One portion of the cooling water enters the mill cylinder from the outside to cool the material, while the other portion directly enters the rod pins to cool the material from the center. Furthermore, to address the issue of belt loosening after prolonged operation, a movable tensioning wheel is incorporated to restore belt tension, thus resolving this problem. Even further, by installing cleaning brushes or hammers inside the filter cylinder, material adsorbed on the filter screen holes is cleaned, solving the clogging problem.
