Technical Field
[0001] This utility model relates to the technical field of solid-state battery processing equipment, specifically to a solid-state battery powder mill that facilitates heat dissipation. Background Technology
[0002] In the current solid-state battery manufacturing process, it is crucial to pulverize the raw materials into powder. This not only improves uniformity, ensures uniform mixing of electrodes and electrolytes and avoids component segregation, but also enhances interparticle contact, reduces voids, lowers interfacial impedance, and regulates material properties, increases specific surface area, and improves reactivity. The fineness and uniformity of the powder directly determine the energy density, rate performance, and cycle life of the battery. In existing processing technologies, solid-state battery raw materials are generally processed using a pulverizer.
[0003] For example, CN 210022355U discloses an ultrafine pulverizer for easy discharge, which includes a chassis, a rotating shaft, a motor housing, a pulverizing bin, blades, and a cover. The motor housing contains a motor, and the output shaft of the motor extends upward into the pulverizing bin. One end of the rotating shaft is connected to a crank handle. The motor housing also contains an electronic control board, and the motor is connected to the electronic control board. A second power contact is provided on the bottom side of the motor housing, and a first power contact is provided on the inner side of the chassis. When the motor housing is tilted, the first and second power contacts disengage from each other. The second power contact is connected to the electronic control board, and the first power contact is connected to a plug, which is connected to the mains power.
[0004] However, the existing powder grinders lack a heat dissipation structure. If used for a long time, they will cause the motor or the powder grinding chamber to overheat. This will not only reduce the service life of the motor, but also affect the electrochemical performance of the solid-state battery raw material powder due to the overheating of the powder grinding chamber.

[0032] The technical solution adopted by this utility model to solve its technical problem is as follows:
[0033] like Figure 1-7 As shown, a solid-state battery pulverizer that facilitates heat dissipation includes a drive structure 1, a pulverizing structure 2 disposed on the drive structure 1, and a heat dissipation structure 3.
[0034] Specifically, the drive structure 1 includes a housing 1.1 and a drive unit 1.2 disposed inside the housing 1.1. The powder grinding structure 2 includes a powder grinding bowl 1.3 and a powder grinding blade 1.4 disposed inside the powder grinding bowl 1.3.

The first heat dissipation pipe 1.6 and the second heat dissipation pipe 1.7 are installed inside the outer shell 1.1, and the output end of the first heat dissipation pipe 1.6 is placed inside the outer shell 1.1, while the output end of the second heat dissipation pipe 1.7 is located below the mixing bowl 1.3.
[0036] The heat dissipation unit 1.5 works by supplying external air to the pulverizer through the first heat dissipation pipe 1.6 and the second heat dissipation pipe 1.7. The first heat dissipation pipe 1.6 and the second heat dissipation pipe 1.7 are installed inside the outer shell 1.1, with the output end of the first heat dissipation pipe 1.6 placed inside the outer shell 1.1. The output end of the second heat dissipation pipe 1.7 is located below the pulverizing bowl 1.3 to dissipate heat from the pulverizing bowl 1.3 and the drive unit 1.2, greatly improving the heat dissipation effect. This not only increases the service life of the drive unit 1.2, but also prevents the electrochemical performance of the solid-state battery raw material powder from deteriorating.
[0037] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, as a further explanation of the heat dissipation implementation method of the powder mixing bowl 1.3, a heat dissipation base 1.8 is provided on the top of the outer shell 1.1, the powder mixing bowl 1.3 is placed on the heat dissipation base 1.8, and the second heat dissipation pipe 1.7 is placed inside the heat dissipation base 1.8. By using the heat dissipation base 1.8 to fit against the bottom of the powder mixing bowl 1.3, the temperature of the powder mixing bowl 1.3 can be conducted to the heat dissipation base 1.8, thereby absorbing the heat of the powder mixing bowl 1.3, and dissipating heat to the heat dissipation base 1.8 through the second heat dissipation pipe 1.7, so as to achieve rapid heat dissipation and cooling of the powder mixing bowl 1.3.
[0038] Specifically, the heat sink 1.8 has several first heat dissipation holes 2.1. The heat dissipation unit 1.5 works to draw in external air and discharge it through the second heat dissipation pipe 1.7.

The use of multiple abutting protrusions 2.7 to abut against the bottom of the powder mixing bowl 1.3 improves the stability and reliability of the powder mixing bowl 1.3.
[0042] Preferably, the abutting protrusions 2.7 form a heat dissipation flow channel 2.8, and the heat dissipation flow channel 2.8 is connected to the heat dissipation hole. Air carrying heat can be discharged from the heat dissipation hole and discharged into the external environment through the flow channel to improve the heat dissipation effect.
[0043] During the entire heat dissipation process, on the one hand, airflow is delivered to the heat sink 18 through the first heat dissipation pipe 1.6. The airflow passes through the first heat dissipation hole 2.1 and connects to the heat dissipation flow channel 2.8, thereby directly acting on the bottom of the powder mixing bowl and being discharged into the external environment through the heat dissipation flow channel 2.8. On the other hand, the temperature of the powder mixing bowl 1.3 is conducted through the contact protrusion 2.7 and exchanges heat with the heat sink 1.8.
[0044] Meanwhile, the heat inside the outer casing 1.1 can also enter the heat sink 1.8 through the second heat dissipation pipe 1.7 for heat dissipation.

The heat dissipation unit 1.5 works to draw in external air and discharge it through the first heat dissipation pipe 1.6. The discharged air carries the heat from the drive unit 1.2 and the inside of the outer box into the external space through the first heat dissipation holes 2.1, so as to achieve rapid cooling and heat dissipation of the drive motor and the inside of the housing 1.1.

The airflow ejected from the first heat dissipation pipe 1.6 can carry away the heat inside the motor cavity 4.3 to ensure heat dissipation.
[0047] Furthermore, a heat dissipation fan 4.4 is mounted on the rotor 4.2 and is mounted inside the motor cavity 4.3. The top of the outer casing 1.1 forms a second heat dissipation hole 2.2. The heat dissipation fan 4.4 and the second heat dissipation hole 2.2 are arranged opposite to each other, further improving the heat dissipation effect on the drive unit 1.2.

The mounting base 3.1 forms a mounting cavity 3.2 for mounting control components. The mounting base 3.1 is provided with an air pipe connection joint 3.3 connecting the first heat dissipation pipe 1.6, the second heat dissipation pipe 1.7 and the heat dissipation unit 1.5. The heat dissipation unit 1.5 is provided with an exhaust fan.

The air is then input into the first heat dissipation pipe 1.6 and the second heat dissipation pipe 1.7 through the air pipe connection joints 3.3 to dissipate heat from the drive unit 1.2 and the powder mixing bowl 1.3.
[0049] The mounting base 3.1 has a heat dissipation groove 3.4 at the top that connects to the outer shell 1.1, and a connecting hole 3.5 at the bottom.
