Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and more specifically, it relates to a cement clinker cooler for cement production. Background Technology

[0002] Cement clinker coolers are crucial equipment in cement clinker production, responsible for the rapid cooling, heat recovery, and transport of high-temperature clinker exiting the rotary kiln. Rapid cooling of cement clinker helps prevent the growth of C3S crystals, the main mineral in the clinker, which improves its early strength and grindability. Simultaneously, it solidifies the molten liquid phase into a glassy substance, containing most of the MgO and C3A, thus improving the stability and chemical resistance of the cement clinker. The recovery of a large amount of heat from the high-temperature clinker is used for heating secondary and tertiary air, drying pulverized coal, and waste heat power generation, which is an important way to reduce the heat consumption during clinker burning and lower production costs. Cooling the high-temperature clinker also facilitates its transport, storage, and processing.

[0003] A search revealed that Chinese utility model patent application number CN202121412768.1 discloses a clinker cooler for cement production, comprising a cooling tank, a first cooling mechanism, a second cooling mechanism, and a third cooling mechanism within the cooling tank. The first cooling mechanism includes a support plate with a circulating cooling water pipe inside. Two guard plates are fixedly connected to the support plate, and a rake plate is located between the two guard plates. A first rod is connected above the rake plate, and a first slider is fitted onto the first rod. A second slider is connected to one end of the first slider. A second rod is located on one side of the second slider, and a vertical plate is connected above the second rod. A rotating shaft is located at one end of the vertical plate, and a third rod is located at one end of the rotating shaft. A motor is located at the other end of the rotating shaft, and a fourth rod is located at one end of the third rod. A third slider is fitted onto the fourth rod, and the fourth rod is hinged to the first rod.

[0004] When cooling cement clinker, the system uses a fan to blow air into the cooling tank to cool the cement clinker. During the cooling process, dust from the cement clinker is dispersed into the surrounding air with the airflow, causing pollution to the surrounding environment. In addition, the system only uses airflow to cool the cement clinker, which is a relatively simple cooling method and has a poor cooling effect. Utility Model Content

[0030] Please see Figures 1-5A cement clinker cooler for cement production includes a cooling tank 1. A discharge hopper 2 is connected to the bottom of the cooling tank 1. Guide seats 29 are fixedly connected to both sides of the discharge hopper 2 at the bottom of the interior of the cooling tank 1, facilitating the flow of cement clinker falling into the discharge hopper. A sealing box 3 is fixedly connected to the top of the cooling tank 1. A sealing gasket 28 is provided between the sealing box 3 and the cooling tank 1 to ensure a tight seal. A connecting pipe 4 is fixedly connected to the top of the sealing box 3, connecting to an external cement clinker conveying pipeline. Because the connecting pipe 4 is connected to the external cement clinker conveying pipeline, air is discharged from the exhaust pipe 5 during the cooling of the cement clinker. The top of the sealed box 3 is fixedly connected to an exhaust pipe 5. A filter screen plate 6 is fixedly connected inside the exhaust pipe 5. The top of the sealed box 3 is fixedly connected to a fixing frame 7. A motor 8 is fixedly installed on the top of the fixing frame 7. A rotating shaft 9 is fixedly connected to the output end of the motor 8. The rotating shaft 9 is rotatably connected to the filter screen plate 6. A rotating plate 10 is fixedly connected to the bottom end of the rotating shaft 9. A first cleaning brush 11 is fixedly connected to the top end of the rotating plate 10. The top end of the first cleaning brush 11 contacts the bottom end of the filter screen plate 6. Multiple air inlet pipes 12 are fixedly connected to the side end of the cooling tank 1. Each of the multiple air inlet pipes 12 is connected to an air supply pipe 13. A fan 14 is installed on the cooling tank 1. The air outlet end of the fan 14 is connected to the air supply pipe 13.

[0031] Specifically, by setting up an exhaust pipe 5 and a filter screen 6, the air used to cool the cement clinker is discharged through the exhaust pipe 5, and the dust in the air is intercepted by the filter screen 6 to prevent the dust from flying into the surrounding air and causing pollution to the surrounding environment. The motor 8 drives the rotating shaft 9, rotating plate 10 and first cleaning brush 11 to rotate, and the first cleaning brush 11 cleans the dust on the filter screen 6 to prevent the filter screen 6 from clogging.

[0032] Please see Figures 1-4The cooling tank 1 has multiple cooling boxes 15 fixedly connected inside. A curved material discharge channel 16 is formed between adjacent cooling boxes 15. The multiple material discharge channels 16 correspond to the positions of multiple air inlet pipes 12. Each cooling box 15 has a water inlet pipe 17 connected to its bottom side. One end of each water inlet pipe 17 leading to the outside of the cooling tank 1 is connected to a first water supply pipe 18. Each cooling box 15 has a water outlet pipe 19 connected to its top side. One end of each water outlet pipe 19 extending to the outside of the cooling tank 1 is connected to a second water supply pipe 20. A water supply pipe 18 and a second water supply pipe 20 are connected to an external cooling tower via a water pump. The water pump allows cooling water to circulate between multiple cooling boxes 15 and the cooling tower. After the water cools the cement clinker, it flows to the cooling tower and is cooled down to facilitate water cooling of the cement clinker. Multiple guide plates 21 are fixedly connected inside the sealed box 3. The bottom ends of the multiple guide plates 21 contact the top ends of the multiple cooling boxes 15 respectively, so that the cement clinker falling from the connecting pipe 4 can fall into the interior of multiple material drop channels 16.

[0033] Specifically, by circulating cooling water inside multiple cooling boxes 15, the temperature of multiple cooling boxes 15 is reduced. As the cement clinker falls inside the material discharge channel 16, the cement clinker is cooled. It is cooled by airflow and water cooling at the same time, which diversifies the cooling methods of cement clinker and improves the cooling effect of cement.

[0034] Please see Figure 3 and Figure 4 Each of the multiple material discharge channels 16 has a movable plate 22 inside. A second cleaning brush 23 is fixedly connected to both ends of each movable plate 22. The second cleaning brush 23 contacts the side end of the corresponding cooling tank 15. Two sliding rods 24 are fixedly connected to the side ends of each movable plate 22. Each sliding rod 24 slides in cooperation with the cooling tank 1. A fixed plate 25 is fixedly connected to one end of each sliding rod 24 extending outside the cooling tank 1. An electric cylinder 26 is fixedly connected to the cooling tank 1. The telescopic rod of the electric cylinder 26 is fixedly connected to the fixed plate 25. Two support rods 27 are fixedly connected to the end of each movable plate 22 away from the sliding rods 24. The support rods 27 slide in cooperation with the cooling tank 1, providing support for the movable plates 22. Protective covers 30 are fixedly connected to the side ends of the cooling tank 1 at positions corresponding to the fixed plate 25 and the support rods 27, providing protection.

[0035] Specifically, the electric cylinder 26 drives the fixed plate 25, multiple sliding rods 24 and multiple moving plates 22 to move. As the multiple moving plates 22 move inside the corresponding material discharge channels 16, the second cleaning brush 23 cleans the cement clinker on the side wall of the cooling box 15, ensuring the cleanliness of the cement clinker surface and ensuring the heat conduction effect of the cooling box 15.

[0036] In summary, when using the overall equipment:

[0037] The external cement conveying pipeline transports cement clinker to the interior of the connecting pipe 4. The cement clinker falls through the connecting pipe 4 into the interior of the sealed box 3, and then through multiple guide plates 21 into multiple discharge channels 16. Simultaneously, the blower 14 blows air into the interior of the cooling tank 1, and the air entering the cooling tank 1 is discharged through the exhaust pipe 5, thus allowing air to circulate inside the cooling tank 1 to cool the cement clinker. The filter screen 6 intercepts dust in the air, preventing dust from scattering into the surrounding air and causing pollution to the surrounding environment. The motor 8 drives the rotating shaft 9, rotating plate 10, and first cleaning brush 11 to rotate, and the first cleaning brush 11 cleans the filter screen. Dust on filter screen 6 is cleaned to prevent clogging. Meanwhile, cooling water is delivered to the interior of multiple cooling boxes 15 through the first water supply pipe 18 and multiple water inlet pipes 17. Water entering the cooling box 15 is discharged through multiple water outlet pipes 19 and the second water supply pipe 20. The cooling water flowing inside the cooling box 15 cools the water inside the material discharge channel 16. At the same time, the electric cylinder 26 drives the fixed plate 25, multiple sliding rods 24 and multiple moving plates 22 to move. As the multiple moving plates 22 move in their respective material discharge channels 16, the second cleaning brush 23 cleans the cement clinker on the side wall of the cooling box 15 to ensure the cleanliness of the cement clinker surface.
