[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figures 1-4 The high-efficiency tempering furnace for producing grinding balls shown includes a tempering furnace body 1. A feed hopper 4 is provided on one side of the tempering furnace body 1, and a discharge pipe 5 is provided on one side of the tempering furnace body 1. Electromagnetic valves are provided in both the feed hopper 4 and the discharge pipe 5. A hollow rotating cylinder 6 is rotatably installed inside the tempering furnace body 1. A stirring device 2 is provided inside the hollow rotating cylinder 6 on the inner wall of the tempering furnace body 1. The stirring device 2 can drive a round rod 21 and several stirring rods 24 through a motor 22 to stir the grinding balls inside the hollow rotating cylinder 6 for tempering processing, so that they move during the tempering process and fully contact the hot air inside the tempering furnace body 1 to achieve a uniform heating effect. During the production of grinding balls, when tempering them using the tempering furnace body 1, the quenched grinding balls are placed into the tempering furnace body 1 from the feed hopper 4, allowing them to fall into the hollow rotating cylinder 6. Then, the heating mechanism inside the tempering furnace body 1 is activated. This heating mechanism can be achieved by drawing air into a wind box via a fan, heating it through a heating wire mesh, and then conveying it into the tempering furnace body 1 to create a high-temperature environment for tempering the grinding balls. Alternatively, other heating components can be used for tempering; therefore, no fixed limitation is imposed. Simultaneously, the stirring device 2 is activated. The grinding balls during tempering are stirred to disperse the accumulated grinding balls, ensuring that the outer surface of the grinding balls can fully contact the hot air inside the tempering furnace body 1 to achieve uniform heating. This improves the tempering effect and product quality of the tempering furnace body 1. After tempering is completed, the drive mechanism inside the tempering furnace body 1 can be activated to drive the hollowed-out rotating drum 6 to rotate. The threaded protrusions 35 inside the drum transport the grinding balls to the discharge pipe 5 for discharge. The drive mechanism can be a drive motor 22 that drives a gear set to rotate, thereby driving the hollowed-out rotating drum 6 to rotate.

[0032] Figure 2 and Figure 3The stirring device 2 shown includes a round rod 21 and several stirring rods 24, wherein the two ends of the round rod 21 are respectively installed through the inner wall of the tempering furnace body 1 on both sides, and several arc-shaped teeth 25 are fixedly installed on the outer surface of the stirring rods 24; several supports 23, wherein the inner wall of one end of the support 23 is sleeved on the outer surface of the stirring rod 24, and the other end is fixedly installed on the outer surface of the round rod 21; a motor 22, wherein one side of the motor 22 is fixedly installed on one side of the tempering furnace body 1, and the output end is fixedly installed on one side of one end of the round rod 21 by means of a coupling. During the tempering process of the grinding balls, the motor 22 can be started to drive the round rod 21 to rotate, which in turn drives several supports 23 and stirring rods 24 to rotate around the round rod 21. This stirs the grinding balls during the tempering process. When the stirring rods 24 and several arc-shaped teeth 25 come into contact with the surface of the grinding balls, they will rotate on the supports 23 according to the distribution of the grinding balls and the contact action, thus performing secondary stirring of the grinding balls. At the same time, the contact friction with the surface of the grinding balls is reduced, making it easier to stir them. This prevents the grinding balls from piling up during the tempering process and allows them to roll around, so that the outer surface of the grinding balls can fully contact the hot air inside the tempering furnace body 1 to achieve a uniform heating effect. This can improve the tempering effect and product quality of the tempering furnace body 1.

[0033] Figure 2 and Figure 3 Bearings 26 are fixedly installed on the outer surfaces of both ends of the circular rod 21 shown. The outer rings of the bearings 26 are fixedly installed on both sides of the inner wall of the tempering furnace body 1. By setting the bearings 26, the rotational wear between the circular rod 21 and the inner wall of the tempering furnace body 1 can be reduced, facilitating the rotation of the circular rod 21. Reinforcing rods 27 are fixedly installed on both sides of the bracket 23. One side of the reinforcing rod 27 is fixedly installed on the outer surface of the circular rod 21. By setting the reinforcing rods 27, the connection area between the bracket 23 and the circular rod 21 can be increased, making the connection more secure and stable, and less prone to breakage or damage.

[0034] Figure 4A protective device 3 is provided on one side of the tempering furnace body 1 on the outer surface of the motor 22. The protective device 3 includes a protective cover 32, a threaded groove 31 on one side of the tempering furnace body 1, a threaded ring block 33, wherein one side of the threaded ring block 33 is fixedly installed on one side of the protective cover 32, and the outer surface thread is inserted into the inner wall of the threaded groove 31. The threaded ring block 33 and the protective cover 32 are both sleeved on the outer surface of the motor 22. A heat dissipation mechanism 34 is provided in the inner wall of the protective cover 32 and is used to blow air to assist the motor 22 in heat dissipation. By setting the protective device 3, the protective cover 32 and the threaded ring block 33 can be fitted onto the outer surface of the motor 22, and the threaded ring block 33 can be spirally inserted into the inner wall of the threaded groove 31. After the protective cover 32 covers the motor 22, it is fixed and limited on the tempering furnace body 1, protecting the outer surface of the motor 22 and preventing damage caused by collision during use or transportation. At the same time, the heat dissipation mechanism 34 accelerates the air circulation speed between the surface of the motor 22 and the inside of the protective cover 32, achieving the effect of heat dissipation. This prevents the temperature generated by the motor 22 during use from accumulating inside the protective cover 32, which would cause the temperature to be too high and damage it. This improves the protective effect and extends the service life of the stirring device 2.

[0035] Figure 4 The heat dissipation mechanism 34 shown includes an air duct frame 341, which is fitted onto the outer surface of the motor 22, with one end of its air inlet penetrating and installed in the inner wall of the protective cover 32; and an air pump 342, one side of which is fixedly installed on the outer surface of the protective cover 32, and its outlet is fixedly installed at the air inlet of the air duct frame 341. By setting up the heat dissipation mechanism 34, when the protective cover 32 is protecting the outer surface of the motor 22, the air pump 342 is activated to draw external air into the interior of the air duct frame 341 to dissipate heat from the outer surface of the motor 22, accelerating the airflow speed on the surface of the motor 22, preventing the temperature generated during use from accumulating inside the protective cover 32, thus avoiding overheating and damage, improving the protective effect and extending the service life of the stirring device 2. The heat dissipation mechanism 34 also includes several filters 343, the outer surfaces of which are all fixedly installed in the inner wall at the outlet of the air duct frame 341. By setting up a filter screen 343, external dust and impurities can be prevented from entering the interior of the air duct frame 341, avoiding blockage and affecting use. Several protrusions 35 are fixedly installed on the outer surface of the protective cover 32, arranged at equal intervals. The protrusions 35 increase the surface roughness of the protective cover 32, making it easier to grip and less prone to slipping during installation, resulting in a more secure grip.

[0036] Working principle: During the tempering process of grinding balls in the production process, the quenched grinding balls are placed into the tempering furnace body 1 from the feed hopper 4, allowing them to fall into the hollow rotating cylinder 6. Then, the heating mechanism inside the tempering furnace body 1 is activated, and the motor 22 is started to drive the round rod 21 to rotate. This, in turn, drives several supports 23 and stirring rods 24 to rotate around the round rod 21, stirring the grinding balls during the tempering process. When the stirring rods 24 and several arc-shaped teeth 25 contact the surface of the grinding balls, they will adjust their contact according to the distribution of the grinding balls and the contact points. Under the action of the support 23, the grinding balls rotate, which agitates them a second time and reduces the friction between the grinding balls and the surface of the grinding balls, making it easier to stir them. This prevents the grinding balls from piling up during the tempering process and makes them roll, so that the outer surface of the grinding balls can fully contact the hot air inside the tempering furnace body 1 to achieve a uniform heating effect. This can improve the tempering effect and product quality of the tempering furnace body 1. After the tempering process is completed, the drive mechanism inside the tempering furnace body 1 can be started to drive the hollow rotating drum 6 to rotate, so that the threaded protrusions 35 inside the drum can transport the grinding balls to the discharge pipe 5 for discharge.

[0037] By setting the protective device 3, the protective cover 32 and the threaded ring block 33 can be fitted onto the outer surface of the motor 22, and the threaded ring block 33 can be spirally inserted into the inner wall of the threaded groove 31. After the protective cover 32 covers the motor 22, it is fixed and limited on the tempering furnace body 1, protecting the outer surface of the motor 22 and preventing damage caused by collision during use or transportation. At the same time, the air pump 342 is started to draw external air into the air guide pipe frame 341 to blow air and dissipate heat on the outer surface of the motor 22, accelerating the air circulation speed on the surface of the motor 22, preventing the temperature generated during use from accumulating inside the protective cover 32, which would cause the temperature to be too high and damage it, thus improving the protective effect and the service life of the stirring device 2.
