[0024] As Figures 1-3 shown, the present embodiment proposes a heat exchange cooling equipment for grinding ball production, which comprises a cooling box 1, a cold water conveying equipment, a grinding ball conveying pipe 10 and a plurality of grinding ball conveying devices.

[0025] The grinding ball conveying pipe 10 is installed on the upper end of the cooling box 1; a plurality of partition plates 3 are arranged side by side on the inner side of the cooling box 1, and the inner cavity of the cooling box 1 is divided into a plurality of cooling cavities by the plurality of partition plates 3, the water temperature inside the plurality of cooling cavities gradually decreases from the side adjacent to the grinding ball conveying pipe 10 to the other side; and the plurality of grinding ball conveying devices are respectively installed on the inner side of the plurality of cooling cavities.

[0026] The cold water conveying equipment is installed on one side of the cooling box 1 for conveying cooling water into the plurality of cooling cavities, and the cold water conveying equipment comprises a cold water storage tank 2 and a water pump 9, the water pump 9 is installed on the cold water storage tank 2, a first water pipe is connected between the input end of the water pump 9 and the cold water storage tank 2, a second water pipe is connected to the output end of the water pump 9, a plurality of branch pipes are connected to the second water pipe, a valve is installed on each of the plurality of branch pipes, the valve is arranged for adjusting the water inflow for cooling, the bottom end of each of the plurality of branch pipes is arranged at the bottom of each of the plurality of cooling cavities, when the water temperature in the cooling cavity rises above the set threshold value, the water pump 9 is started to work to convey the cold water in the cold water storage tank 2 into the plurality of cooling cavities, so as to synchronously reduce the water temperature in the plurality of cooling cavities; and an electronic thermometer is installed on the cooling box 1 for measuring the water temperature in the plurality of cooling cavities, respectively, the electronic thermometer is arranged for monitoring the change of the water temperature in the corresponding cooling cavity.

[0027] An overflow gap 8 is arranged on the top side of each of the plurality of cooling cavities, after the cooling water is injected, the water temperature in the cooling cavity is reduced, and the water level in the cooling cavity is increased, the excess water is discharged through the overflow gap 8.

[0028] Specifically, the grinding ball to be cooled is discharged into the cooling cavity adjacent to one side of the grinding ball conveying pipe 10, which is the rightmost side by default in the embodiment. The water in the rightmost cavity has the highest temperature, so the grinding ball is preliminarily cooled in the rightmost cavity. The grinding ball is conveyed to the next cooling cavity by the grinding ball conveying device, and the process is repeated to achieve step-by-step cooling of the grinding ball, thereby avoiding cracking and deformation caused by rapid cooling of the grinding ball and improving the production quality of the grinding ball. It should be noted that in order to protect the grinding ball, rubber pads are provided on the cushion 12 and the guide plate 11, which can act as a buffer.

[0029] Embodiment Two

[0030] As shown in Figure 2 and Figure 3 , the heat exchange cooling equipment for grinding ball production proposed in this embodiment includes a conveying belt device and a plurality of hoppers 7. The conveying belt device includes a transmission belt 5, a servo motor 6, two transmission rollers, and two installation upright plates 4 arranged side by side. The two installation upright plates 4 are vertically installed on the inner side of the cooling cavity.

The plurality of hoppers 7 are installed on the outer periphery of the transmission belt 5. The plurality of hoppers 7 are each provided with a through hole. This arrangement can prevent the water in the previous cooling cavity from being brought into the next cooling cavity. After the grinding ball falls into the hopper 7, the hopper 7 and the grinding ball move upward with the rotation of the transmission belt 5. When the grinding ball moves to the top position and starts to flip to the other side, the grinding ball falls into the second cooling cavity. At the same time, the plurality of hoppers 7 can stir the water when moving, which helps to improve the uniformity of the mixing between the newly injected cooling water and the original water.

[0031] The plurality of hoppers 7 are installed equidistantly on the transmission belt 5. When the hopper 7 moves to the top position of the transmission belt 5, the uppermost hopper 7 on the side of the transmission belt 5 is located above the partition plate 3. It should be noted that the hopper 7 referred to here is not the topmost hopper 7, but the hopper 7 below the topmost hopper 7. Through the above structure, the grinding ball can fall onto the next hopper 7 after falling, and then roll into the next cooling cavity under the blockage of the hopper 7.
