Description

Technical Field

[0001] The invention relates to the technical field of ceramic firing equipment, in particular to a firing equipment for aluminum nitride ceramic grinding balls. Background Art

[0002] Aluminum nitride ceramic grinding balls are made through processes such as batching, grinding, powder making, molding, drying, and firing. They are mainly used as grinding media and are widely used. Firing is a very important step, which will directly determine the strength and wear resistance of the grinding balls. However, there are still some problems in the use of existing firing equipment, as follows:

[0003] The existing firing equipment needs to place a certain number of grinding balls in the firing equipment when firing the grinding balls. However, the bearing structure used for placing the grinding balls in the existing firing equipment is a simple tray. The grinding balls are stacked in the firing space of the firing equipment and then fired together. However, since the internal grinding balls cannot rotate during the firing process, the grinding balls are heated unevenly during firing. The side facing the heat source is heated quickly, while the other side is heated slowly. This may cause the grinding balls to crack due to uneven heating during the firing process. In addition, stacking the grinding balls together may cause dents or firing bonding at the contact parts of adjacent grinding balls due to the force generated by long-term stacking during the firing process, which greatly reduces the firing quality and yield of the grinding balls. For this reason, we propose a firing equipment for aluminum nitride ceramic grinding balls. Summary of the invention

[0036] Compared with the prior art, the present application is provided with a container assembly 9 for placing grinding balls, in which the grinding balls are not stacked, so that the grinding balls can be prevented from sticking and dents caused by pressure contact during the sintering process, and the integrity of the grinding balls during the firing process is guaranteed to the greatest extent. At the same time, the inner shell assembly 7 can also swing slightly after being placed inside the outer shell 1, so that the grinding balls can roll inside the container assembly 9, so that the grinding balls can be heated more evenly during the firing process to improve the firing quality of the grinding balls. At the same time, a lifting assembly 11 is provided, and the linkage assembly 10 can be driven up and down by the driving of the lifting assembly 11, and then the container assembly 9 can be driven to rotate. In this way, the grinding balls can be combined with the small swing of the inner shell assembly 7 to realize the axial rotation of the grinding balls inside the container assembly 9, and can also roll inside the container assembly 9 with the swing of the inner shell assembly 7, so that the grinding balls can be prevented from being fired in one place all the time, thereby preventing the grinding balls from sticking during firing and preventing the grinding balls from being stacked and fired for a long time. The firing quality of the grinding balls is further improved.

[0037] See also Figure 1-2 , a firing device for aluminum nitride ceramic grinding balls, comprising an air intake pipe 3, one end of which is connected to an external air supply device, and the other end of which is connected to a top thread of an inner shell component 7 and sealed, and the connection end is a hose structure;

[0038] In this embodiment, it should be noted that during the firing process of the grinding balls placed inside the inner shell component 7, the small swing of the inner shell component 7 can ensure the air supply stability of the air intake pipe 3, thereby ensuring the stability of the combustion.

[0040] In this embodiment, it should be noted that this can ensure that the flame generated by the combustion can directly burn each grinding ball at the location of the grinding ball, thereby ensuring the direct conduction of heat during firing and ensuring the firing effect. Moreover, since the interval between each adjacent separated combustion module 8 is small, the heat of the combustion flame ejected from the separated combustion module 8 can be well concentrated near the grinding ball, ensuring full utilization of the heat.

When the driving device 4 is pulled outward, the inner shell component 7 is engaged with the transmission component 5. In this way, the transmission component 5 can drive the inner shell component 7 to rotate when it rotates, that is, a small swing of the inner shell component 7 is realized to drive the grinding balls in the internal container component 9 to roll horizontally, thereby ensuring the firing effect.
