[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, a cooling cylinder body is provided, and aluminum ash is placed inside the installation frame. The aluminum ash will enter the cooling cylinder body along the inclined surface of the wedge plate, and the first motor drives the spiral body to rotate clockwise. At the same time, the first motor drives the first synchronous belt transmission assembly to transmit clockwise, and the first synchronous belt transmission assembly drives the connecting rod to rotate clockwise, and the connecting rod drives the first gear to rotate clockwise, and the first gear drives the second gear to rotate counterclockwise, and the second gear drives the cooling cylinder body to rotate counterclockwise. The clockwise rotation of the spiral body and the counterclockwise rotation of the cooling cylinder body cooperate to effectively push the aluminum ash forward, avoid the accumulation or blockage of the aluminum ash inside the cooling cylinder body, make the transmission more uniform and stable, and make the aluminum ash more fully stirred and turned inside the cooling cylinder body, increase the chance of the aluminum ash contacting the inner wall of the cooling cylinder body, thereby improving the cooling efficiency and effect.

[0018] In the present invention, a screening net is provided, and the crushed aluminum ash falls onto the top of the screening net. At this time, the second synchronous belt transmission assembly drives the mounting plate to transmit counterclockwise, and the mounting plate drives the first ball to make counterclockwise circular motion. The first ball and the second ball are constantly staggered, so that the screening cylinder vibrates. The sleeve is sleeved on the side wall of the T-type cylinder and continuously slides on the side wall of the T-type cylinder. The spring rod will also be continuously compressed and stretched, aggravating the vibration. The sleeve is sleeved on the side wall of the screening cylinder to prevent the screening cylinder from being misplaced and sliding out from the top of the mounting disk. The screening cylinder drives the screening net to vibrate, and the screening net screens the aluminum ash. When it passes through the truncated cone cylinder and falls onto the top of the next-level screening net, the rotating shaft drives the second crushing leaf to rotate counterclockwise inside the truncated cone cylinder to crush the aluminum ash again, making the aluminum ash more delicate and convenient for subsequent processing.

[0019] In the present invention, a silicon carbide coating is provided, and a silicon carbide coating is provided inside the cooling tube body. The silicon carbide coating has a unique crystal structure, and the orderly arrangement of atoms is conducive to the transmission of thermal vibrations, thereby promoting heat conduction. The high purity reduces impurities, reduces the thermal resistance caused by impurities, and makes heat conduction smoother. The good thermal stability enables it to maintain structural stability at high temperatures without phase change or structural damage due to temperature changes, ensuring stable thermal conductivity. The higher thermal conductivity enables it to transfer heat more effectively than common coating materials. When it has good compatibility with the substrate and good bonding, the interface thermal resistance is small, and the heat can be quickly transferred between the coating and the substrate to improve the overall thermal conductivity, thereby increasing the thermal conductivity of the cooling tube body, and quickly transmitting the temperature of the aluminum ash to the cooling tube body. The cooling tube body releases the heat to accelerate the cooling of the aluminum ash.

[0020] In the present invention, by providing a rotating blade, the second gear drives the third gear to rotate clockwise, the third gear drives the fixed rod to rotate clockwise, the fixed rod drives the rotating blade to make a clockwise circular motion, and the third gear, the fixed rod and the rotating blade are provided with two, and are relatively mirror-image-designed, thereby improving the heat exchange efficiency, making the water in the water tank more fully mixed, avoiding the occurrence of local water temperature unevenness, enhancing the heat exchange effect with the outside, improving the cooling efficiency of aluminum ash, and promoting the flow of water in the water tank, which helps to dissipate heat to the surrounding environment faster, and the disturbance of the water flow can reduce the deposition of impurities and the formation of scale in the water, thereby extending the service life and maintenance cycle of the water tank.

[0021] In the present invention, by providing a rotating shaft, the aluminum ash after cooling may clump, and the aluminum ash falls onto the receiving plate through the T-type cylinder. At this time, the second motor drives the third synchronous belt transmission assembly to transmit counterclockwise, and the third synchronous belt transmission assembly drives the rotating shaft to rotate counterclockwise, and the rotating shaft drives the receiving plate to rotate counterclockwise, so as to throw the aluminum ash toward the inner wall of the screening cylinder to break up the aluminum ash. The aluminum ash is then crushed by the first crushing leaf to prevent the aluminum ash from being too large and stuck in the discharge cylinder and unable to flow out.

The disturbance of the water flow can reduce the deposition of impurities and the formation of scale in the water, and extend the service life and maintenance cycle of the water storage box 48.

[0038] Working principle:

[0039] The first step is to start the first motor 12 and put the aluminum ash into the installation frame 22. The aluminum ash will enter the cooling cylinder body 19 along the inclined surface of the wedge plate 23. The first motor 12 drives the spiral body 13 to rotate clockwise. At the same time, the first motor 12 drives the first synchronous belt transmission assembly 15 to transmit clockwise. The first synchronous belt transmission assembly 15 drives the connecting rod 16 to rotate clockwise. The connecting rod 16 drives the first gear 17 to rotate clockwise. The first gear 17 drives the second gear 18 to rotate counterclockwise. The second gear 18 drives the cooling cylinder body 19 to rotate counterclockwise. The clockwise rotation of the spiral body 13 and the counterclockwise rotation of the cooling cylinder body 19 will effectively push the aluminum ash forward to avoid the accumulation or blockage of the aluminum ash inside the cooling cylinder body 19, making the transmission more uniform and stable, and making the aluminum ash more fully stirred and turned in the cooling cylinder body 19, increasing the chance of the aluminum ash contacting the inner wall of the cooling cylinder body 19, thereby improving the cooling efficiency and effect.

[0040] In the second step, a silicon carbide coating 44 is arranged inside the cooling cylinder body 19. The silicon carbide coating 44 has a unique crystal structure, and the orderly arrangement of atoms is conducive to the transmission of thermal vibrations, thereby promoting heat conduction. The high purity reduces impurities, reduces the thermal resistance caused by impurities, and makes heat conduction smoother. The good thermal stability enables it to maintain structural stability at high temperatures without phase change or structural damage due to temperature changes, ensuring stable thermal conductivity. The higher thermal conductivity enables it to transfer heat more effectively than common coating materials. When it has good compatibility with the substrate and is well combined with the substrate, the interface thermal resistance is small, and the heat can be quickly transferred between the coating and the substrate to improve the overall thermal conductivity, thereby increasing the thermal conductivity of the cooling cylinder body 19 and quickly transmitting the temperature of the aluminum ash to the cooling cylinder body 19. The cooling cylinder body 19 releases the heat to accelerate the cooling of the aluminum ash.

[0041] In the third step, the second gear 18 drives the third gear 45 to rotate clockwise, the third gear 45 drives the fixed rod 46 to rotate clockwise, and the fixed rod 46 drives the rotating blade 47 to make a clockwise circular motion. There are two third gears 45, fixed rods 46 and rotating blades 47, and they are designed to be relatively mirror images, so as to improve the heat exchange efficiency, make the water in the water tank 48 more fully mixed, avoid the occurrence of local water temperature unevenness, enhance the heat exchange effect with the outside, improve the cooling efficiency of aluminum ash, promote the flow of water in the water tank 48, help heat to be dissipated to the surrounding environment faster, and the disturbance of the water flow can reduce the deposition of impurities and the formation of scale in the water, thereby extending the service life and maintenance cycle of the water tank 48.

[0042] In the fourth step, the aluminum ash may clump after cooling, and the aluminum ash falls onto the receiving plate 42 through the T-type cylinder 21. At this time, the second motor 32 drives the third synchronous belt transmission assembly 38 to transmit counterclockwise, and the third synchronous belt transmission assembly 38 drives the rotating shaft 39 to rotate counterclockwise, and the rotating shaft 39 drives the receiving plate 42 to rotate counterclockwise, and the aluminum ash is thrown toward the inner wall of the screening cylinder 25 to break up the aluminum ash. The aluminum ash is then crushed by the first crushing leaf 41 to prevent the aluminum ash from being too large and stuck in the discharge cylinder 26 and unable to flow out.

[0043] In the fifth step, the crushed aluminum ash falls above the screening net 27. At this time, the second synchronous belt transmission assembly 33 drives the mounting plate 34 to drive counterclockwise, and the mounting plate 34 drives the first ball 36 to do counterclockwise circular motion. The first ball 36 and the second ball 37 are constantly staggered, so that the screening cylinder 25 vibrates, and the collar 35 is sleeved on the side wall of the T-type cylinder 21 and continuously slides on the side wall of the T-type cylinder 21. The spring rod 24 will also be continuously compressed and stretched, aggravating the vibration. The collar 35 is sleeved on the side wall of the screening cylinder 25 to prevent the screening cylinder 25 from being dislocated and sliding out from the top of the mounting plate 34. The screening cylinder 25 drives the screening net 27 to vibrate, and the screening net 27 screens the aluminum ash. After passing through the truncated cone cylinder 28, it falls above the next-level screening net 27. When inside the truncated cone cylinder 28, the rotating shaft 39 drives the second crushing leaf 43 to rotate counterclockwise to crush the aluminum ash again, making the aluminum ash more delicate and convenient for subsequent processing.
