[0002] Ash cooler is a device used to cool boiler ash or other high-temperature materials. It is an important equipment in industrial production and has the advantages of good cooling effect, low noise and simple operation.

[0003] The working principle of the ash cooler is mainly based on the principle of heat exchange. When high-temperature ash or materials enter the ash cooler, heat is exchanged with the cooling medium inside the ash cooler, such as water or air, so that the temperature of the ash gradually decreases.

During operation, the ash to be cooled is poured into the ash cooling box 1 through the material feeding port, the motor 11 is turned on, and the motor 11 drives the driving shaft 12 and the driven shaft 13 The shaft 13 and the conveyor belt 14 rotate, and the conveyor belt 14 drives the supporting assembly to circulate and rotate inside the cold ash box 1. The supporting assembly brings the ash inside the cold ash box 1 from the bottom of the cold ash box 1 to a high place, and the ash then falls from a high place to form a circulating flow. When the ash circulates, the cold air cools the ash through the air circulation assembly. This step is formed by the setting of the motor 11, the driving shaft 12, the driven shaft 13 and the conveyor belt 14 to form an ash circulation flow structure, which realizes the function of the ash circulating inside the cold ash box 1, solves the problem of the small contact area with the air caused by the different static conditions of the ash when cooling inside the cold ash box 1, increases the contact area between the ash and the cold air, thereby increasing the cooling speed of the ash and saving the time for cooling the ash.

[0025] like Figure 2 and Figure 3As shown, the supporting assembly includes a supporting plate 2, a spring 21, a scraper 22, a limit plate 23 and a side plate 24. The supporting plate 2 is hinged to the outer wall of the conveyor belt 14. The supporting plate 2 is provided with multiple groups on the side wall of the conveyor belt 14 and is evenly distributed on the side wall of the conveyor belt 14. The scraper 22 is slidably connected inside the supporting plate 2, and the spring 21 is fixedly connected between the scraper 22 and the supporting plate 2. The spring 21 is provided with multiple groups inside the supporting plate 2. The side wall of the conveyor belt 14 close to the supporting plate 2 is fixedly connected to the limit plate 23, and the side plate 24 is fixedly connected to the side wall of the supporting plate 2 away from the limit plate 23. A pair of side plates 24 are provided on the side wall of the supporting plate 2 and are symmetrically arranged. During operation, when the conveyor belt 14 rotates, it drives the supporting plate 2, the spring 21, the scraper 22, the limit plate 23 and the side plate 24 to rotate. When the supporting plate 2 is at the lowest point, it moves vertically downward, and the scraper 22 is supported by the spring 21 and contacts the bottom of the cold ash box 1. When the material plate 2 moves to the highest point, the material plate 2 rotates under the action of gravity and approaches the conveyor belt 14, so that the side plates 24 contact the conveyor belt 14, and the ash between the material plate 2 and the side plates 24 falls to the bottom of the cold ash box 1, so that the ash forms a circulation flow in the cold ash box 1. This step forms an ash circulation flow structure through the setting of the material plate 2, spring 21, scraper 22, limit plate 23 and side plate 24, thereby realizing the function of circulating the ash inside the cold ash box 1, solving the problem of insufficient contact between the ash and the air caused by the accumulation of ash inside the cold ash box 1, increasing the contact area between the ash and the cooling air, and accelerating the cooling speed of the ash.

[0026] like Figure 2 and Figure 4As shown, the air circulation component includes an air inlet pipe 3, a bellows 31, an air outlet 32, a filter 33 and an exhaust pipe 34. The air inlet pipe 3 is fixedly connected to the outer wall of the cold ash box 1, the bellows 31 is fixedly connected to the inner wall of the cold ash box 1 close to the air inlet pipe 3, the bellows 31 and the air inlet pipe 3 are communicated with the air inlet pipe 3 through a pipe, the air outlet 32 ​​is opened on the side wall of the bellows 31 close to the conveyor belt 14, and multiple groups of air outlets 32 are arranged on the side wall of the bellows 31. The filter 33 is fixedly connected to the outer wall of the cold ash box 1 away from the air inlet pipe 3, the exhaust pipe 34 is fixedly connected to the side wall of the filter 33 away from the cold ash box 1, and the exhaust pipe 34 is communicated with the inside of the cold ash box 1 through the filter 33. During operation, the air inlet pipe 3 is connected to the outside of the cold air, and the cold air is discharged from the air outlet 32 ​​through the air inlet pipe 3 and the air outlet 32 ​​to cool the ash on the supporting plate 2. The exhaust pipe 34 is connected to a vacuum pump to extract the air in the cold ash box 1 to the outside, and the filter 33 filters the exhausted air. In this step, the air circulation structure is formed by the arrangement of the air inlet pipe 3, the air box 31, the air outlet 32, the filter 33 and the exhaust pipe 34, so as to realize the function of the air circulating in the cold ash box 1, solve the problem of the slow flow rate of the air in the cold ash box 1, improve the uniformity of the air when entering the cold ash box 1, reduce the time that the hot air stays in the cold ash box 1, and increase the speed of the ash cooling.

[0027] like Figure 4 As shown, the inner wall of the cold ash box 1 near the driving shaft 12 is fixedly connected with a fixed plate 4, and the side wall of the fixed plate 4 near the driving shaft 12 is fixedly connected with a rubber rod 41. Multiple groups of rubber rods 41 are arranged on the side wall of the fixed plate 4 and are evenly distributed on the side wall of the fixed plate 4. During operation, the conveyor belt 14 drives the supporting plate 2 to rotate inside the cold ash box 1. When the supporting plate 2 is close to the fixed plate 4, the supporting plate 2 collides with the rubber rod 41 when continuing to rotate, causing the supporting plate 2 to vibrate and shake off the dust adhered to the surface of the supporting plate 2. This step forms an ash shaking structure through the setting of the fixed plate 4 and the rubber rod 41, which realizes the function of shaking off the ash adhered to the surface of the supporting plate 2, solves the problem of ash adhered to the surface of the supporting plate 2, and reduces the problem of ash adhered to the surface of the supporting plate 2, resulting in the remaining ash being difficult to cool.

[0028] like Figure 1 As shown, the outer side wall of the cold ash box 1 near the bottom is fixedly connected with a fixing frame 5, and the bottom of the fixing frame 5 is fixedly connected with a support leg 51. The support legs 51 are arranged in multiple groups at the bottom of the cold ash box 1 and are symmetrically arranged. During operation, the fixing frame 5 and the support legs 51 fix and support the equipment. This step supports and fixes the equipment through the setting of the fixing frame 5 and the support legs 51, reduces the possibility of the equipment tipping over, and improves the stability of the equipment during use.

[0029] like Figure 1As shown, the end of the leg 51 away from the fixing frame 5 is fixedly connected with a gasket 6, and the gasket 6 is set at the bottom of multiple groups of legs 51. During operation, when the equipment is placed in the working area, the gasket 6 contacts the ground, and the vibration generated inside the cold ash box 1 is weakened. This step reduces the shock of the equipment through the setting of the gasket 6, thereby reducing the situation where the vibration is transmitted to other equipment and causes damage.

[0030] like Figure 1 As shown, a sealing cover is provided at the top feed port of the cold ash box 1. During operation, after ash is added into the cold ash box 1, the equipment is sealed by the sealing cover to reduce the leakage of dust or foreign matter, provide sealing inside the cold ash box 1, and increase the cooling effect of the ash.

[0031] During operation, the ash to be cooled is poured into the cold ash box 1 through the feed port, and the motor 11 is turned on. The motor 11 drives the driving shaft 12, the driven shaft 13 and the conveyor belt 14 to rotate. The conveyor belt 14 drives the supporting assembly to circulate inside the cold ash box 1. The supporting assembly brings the ash inside the cold ash box 1 from the bottom of the cold ash box 1 to a high place, and the ash falls from a high place to form a circulating flow. When the ash circulates, the cold air cools the ash through the air circulation assembly. When the conveyor belt 14 rotates, it drives the supporting plate 2 and the spring 21, the scraper 22, the limit plate 23 and the side plate 24 rotate. When the supporting plate 2 is at the lowest point, it moves vertically downward. The scraper 22 is supported by the spring 21 and contacts the bottom of the cold ash box 1. When the conveyor belt 14 drives the supporting plate 2 to rotate clockwise, the limit plate 23 contacts the side wall of the supporting plate 2, supporting the supporting plate 2 so that the supporting plate 2 is perpendicular to the conveyor belt 14. The ash is driven upward by the supporting plate 2, and the side plate 24 acts as a barrier. When the supporting plate 2 moves to the highest point, the supporting plate 2 rotates under the action of gravity and moves toward the conveyor belt 14 The ash on the supporting plate 2 is cooled by the conveyor belt 14. The ash between the supporting plate 2 and the side plate 24 falls to the bottom of the cold ash box 1, so that the ash forms a circulation flow in the cold ash box 1. The air inlet pipe 3 is connected to the cold air. The cold air passes through the air inlet pipe 3 and the air outlet 32 ​​and is discharged from the air outlet 32 ​​to cool the ash on the supporting plate 2. The air extraction pipe 34 is connected to the vacuum pump to extract the air in the cold ash box 1 outwards. The filter 33 filters the exhausted air. When the conveyor belt 14 drives the supporting plate 2 to rotate inside the cold ash box 1, When the supporting plate 2 approaches the fixed plate 4, it continues to rotate and collides with the rubber rod 41, causing the supporting plate 2 to vibrate, shaking off the dust adhering to the surface of the supporting plate 2. The fixing frame 5 and the support legs 51 fix and support the equipment. When the equipment is placed in the working area, the gasket 6 contacts the ground, reducing the vibration generated inside the cold ash box 1. After the ash is added to the cold ash box 1, the equipment is sealed by the sealing cover to reduce the overflow of dust or foreign matter, provide sealing inside the cold ash box 1, and increase the ash cooling effect.
