Description

[0002] Rotary kilns, also known as rotary kilns, are widely used in many industrial fields and play an important role in production. They are core equipment in industries such as cement, metallurgy, chemicals, and lime.

[0003] In the cement production process, a rotary kiln consists of a cylindrical structure with a certain inclination. The cylinder is heated at a high temperature from the outside and is called a high-temperature drum. The rotation of the high-temperature drum promotes the stirring of materials inside the kiln, allowing the materials to mix with each other and then fully contact with the catalytic reduction gas to react and process the materials. The materials are then conveyed out after being processed by the high-temperature drum.

[0004] However, during the current material discharge process after processing, the material temperature is relatively high. After discharge, the material needs to be cooled, which consumes a lot of time. At the same time, dust will spread during the discharge process, affecting the air quality at the discharge point.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Combination Figure 1 , Figure 2 and Figure 5 As shown in the embodiment of the present invention, a rotary kiln discharge heat absorption and dust suppression device is installed on the rotary kiln body 1. The discharge heat absorption and dust suppression device includes a discharge hood 2 rotatably connected to the end of the rotary kiln body 1. A guide plate 3 is fixedly connected to the lower part of the discharge hood 2. An installation plate 4 is fixedly connected to the top of the guide plate 3. A plurality of bag mounting frames 5 are fixedly connected to the installation plate 4. Dust collection bags 6 are fixedly connected to the bag mounting frames 5.

[0037] The top of the mounting plate 4 is provided with an exhaust assembly, which is used to promote the flow of gas to the dust collector bag 6.

[0038] A cooling component is provided at the bottom of the guide plate 3 to cool the material. During operation, after the material is processed in the rotary kiln, it is discharged through the discharge hood 2. The material slides down the guide plate 3. During the sliding process, the exhaust component and the cooling component work. The exhaust component causes the dust diffused from the material to flow to the dust collector bag 6 and be absorbed by the dust collector bag 6. Finally, the gas is discharged through the exhaust component, which helps to reduce the diffusion of dust and reduce the impact of dust diffusion on the air quality of the working environment. At the same time, during the sliding process, the cooling component absorbs heat and cools the material, which helps to lower the temperature of the material and reduces the need for subsequent cooling treatment.

[0039] Combination Figure 1 , Figure 5 and Figure 6 As shown, the exhaust assembly includes a protective cover 7, which is fixedly connected to the top of the mounting plate 4. The side wall of the guide plate 3 is fixedly connected to an air outlet 8, an air guide 9, an air outlet 10, and an air guide plate 13. The air outlet 8, air guide 9, air outlet 10, and air guide plate 13 are sequentially connected to the protective cover 7. An exhaust component is provided at the top of the air guide 9 to promote gas flow. An impact component is provided inside the air guide plate 13 to promote vibration of the bottom surface of the guide plate 3. During operation... During the material's descent, the exhaust components promote the airflow within the guide plate 3 towards the dust collector bag 6, which facilitates the dust collector bag 6's absorption of dust. The air then passes sequentially through the first air outlet 8, the guide duct 9, the second air outlet 10, and the guide plate 13. In this process, the flowing air can, on the one hand, remove the temperature from the bottom surface of the guide plate 3, which helps to lower the material's temperature; on the other hand, it pushes the striking components, causing the striking components to vibrate the bottom surface of the guide plate 3, which helps to prevent the material from caking on the bottom surface of the guide plate 3.

[0040] Combination Figure 5 and Figure 10 As shown, the exhaust system includes a motor 11, which is fixedly connected to the top of the air duct 9. The rotating shaft of the motor 11 passes through the top of the air duct 9 and is fixedly connected to a fan blade 12. During operation, the motor 11 is started, and the rotating shaft of the motor 11 drives the fan blade 12 to rotate, discharging the air in the protective cover 7 sequentially to the exhaust duct 10 and the air guide plate 13. This promotes airflow and facilitates the flow of dust to the dust collector bag 6, promoting dust adsorption on the dust collector bag 6. At the same time, as the gas is discharged through the air guide plate 13, the gas can carry away the temperature of the bottom surface of the guide plate 3, which helps to reduce the temperature of the material inside the guide plate 3.

[0041] Combination Figure 6 and Figure 7As shown, the striking component includes multiple cylindrical shafts 14, which are linearly rotatably connected to the inner wall of the air guide plate 13. Blades 15 are fixedly connected to each of the cylindrical shafts 14. A striking ball 16, made of rubber, is fixedly connected to the middle of the end of each blade 15 away from the cylindrical shaft 14 via a rubber rod. During operation, as the motor 11 operates, the air flowing through the air guide plate 13 causes the blades 15 to rotate, which in turn drives the striking ball 16. Reciprocatingly striking the bottom surface of the guide plate 3 helps to promote the vibration of the bottom surface of the guide plate 3. On the one hand, this facilitates the material feeding, and on the other hand, it helps to prevent the material from caking on the inner wall of the guide plate 3, which would affect the cooling effect of the material. It should be noted that the collision volume between the striking ball 16 and the bottom surface of the inner wall of the guide plate 3 needs to meet the following condition: that is, the frictional force generated after the striking ball 16 collides with the guide plate 3 is less than the rotational force of the blade 15 driven by the wind. This ensures that the wind force is sufficient to support the reciprocating striking of the striking ball 16.

[0042] Combination Figure 6 and Figure 7 As shown, the side wall of the air guide plate 13 is provided with heat sinks 17, and there are multiple sets of heat sinks 17 arranged in a linear array.

[0043] Combination Figure 6 and Figure 7 As shown, two air guide grooves 18 are formed through the side wall of the air guide plate 13 near the air outlet duct 2 10. Guide plates 19 are fixedly connected to the side walls of the two air guide grooves 18. During operation, the heat sink 17 helps to cool the gas flowing inside the air guide plate 13 and the bottom surface of the guide plate 3, thereby reducing the temperature of the material. On the other hand, the temperature of the material is conducted to the air guide plate 13 through the guide plate 3. The heat sink 17 helps to cool the air guide plate 13, which in turn helps to reduce the temperature of the material. Through the air guide grooves 18 and guide plates 19, as the gas flows from the air outlet duct 2 10 to the air guide plate 13, some of the gas will be blown towards the heat sink 17 through the air guide grooves 18, which helps to dissipate heat from the heat sink 17 and thus helps to reduce the temperature of the material.

[0044] Combination Figure 2 and Figure 9As shown, the cooling component includes a cooling pipe 20, which is laid on the inner bottom surface of the guide plate 3. A heat-absorbing cover 21 is fixedly connected to the inner wall of the guide plate 3, and the heat-absorbing cover 21 is clipped onto the cooling pipe 20. An outlet pipe 22 and an inlet pipe 23 are respectively provided at both ends of the cooling pipe 20. A water supply mechanism is provided on the bottom surface of the guide plate 3 to supply water into the cooling pipe 20. During operation, during the material feeding process, the heat-absorbing cover 21 absorbs heat from the material, promoting a decrease in material temperature. Simultaneously, the heat-absorbing cover 21 is configured as an arc shell. The structure of the heat-absorbing cover 21 increases the contact area between the heat-absorbing cover 21 and the material, which helps to improve the heat absorption efficiency and thus promotes the reduction of the material temperature. At the same time, the water supply mechanism works continuously during the material sliding process, which helps to remove the heat absorbed on the heat-absorbing cover 21, promotes the reduction of the temperature of the heat-absorbing cover 21, and thus promotes the heat absorption performance of the heat-absorbing cover 21. During the continuous operation of the water supply mechanism, since the cooling pipe 20 is in contact with the bottom surface of the guide plate 3, it helps to cool the guide plate 3, which in turn helps to reduce the material temperature.

[0045] Combination Figure 3 and Figure 9 As shown, the water supply mechanism includes a water pump 24 and a water tank 30. The water tank 30 is placed on the ground. The water pump 24 is fixedly connected to the bottom surface of the guide plate 3. A water delivery pipe 31 is fixedly connected to the water inlet end of the water pump 24. The end of the water delivery pipe 31 away from the water pump 24 is fixedly connected to the bottom of the water tank 30. A solenoid three-way valve 25 is fixedly connected to the water outlet end of the water pump 24. One of the output ends of the solenoid three-way valve 25 is fixedly connected to the liquid inlet pipe 23. A return pipe 32 is fixedly connected to the top of the water tank 30. The end of the return pipe 32 away from the water tank 30 is fixedly connected to the liquid outlet pipe 22. During operation, when the material slides down... During the process, the electromagnetic three-way valve 25 controls the connection between the liquid inlet pipe 23 and the water pump 24. The water pump 24 starts and pumps the water in the water tank 30 into the cooling pipe 20 through the return pipe 32. The water flows in the cooling pipe 20, cooling the heat absorption cover 21 on the one hand and the bottom surface of the guide plate 3 on the other. Finally, the water flows back to the water tank 30 through the liquid outlet pipe 22 and the return pipe 32. The heated water is stored in the water tank 30 through the return pipe 32 and can be used for workers to bathe, etc. A water inlet pipe is also connected through the water tank 30 to replenish the cooling water inside the water tank 30.

[0046] Combination Figure 8 and Figure 9As shown, the cooling assembly also includes a spraying mechanism, which includes a conveying pipe 26 and a spray pipe 27. The spray pipe 27 is fixedly connected to the top inner wall of the guide plate 3, and multiple spray nozzles 28 are fixedly connected to the spray pipe 27. The lower end of the conveying pipe 26 is fixedly connected to the output end of the electromagnetic three-way valve 25, and the upper end of the conveying pipe 26 passes through the side wall of the guide plate 3 and is fixedly connected to the spray pipe 27. During operation, when it is necessary to clean the inner bottom surface of the guide plate 3 and the heat absorption cover 21, the electromagnetic three-way valve 25 controls the water pump 24 to connect with the conveying pipe 26. The water pump 24 pumps water from the water tank 30 into the conveying pipe 26 and sprays it from the spray nozzles 28 onto the inner bottom surface of the guide plate 3 and the heat absorption cover 21. This helps to prevent the material from caking and solidifying on the guide plate 3 and the heat absorption cover 21, which would affect the cooling of the material.

[0047] Combination Figure 8 As shown, the top of the heat absorption cover 21 is fixedly connected to an inclined plate 29; during operation, the inclined plate 29 helps to prevent material residue from remaining on the top of the heat absorption cover 21.

[0048] Working principle: After the material is processed in the rotary kiln, it is discharged through the discharge hood 2. The material slides down through the guide plate 3. During the process of the material sliding down, the motor 11 is started. The rotating shaft of the motor 11 drives the fan blade 12 to rotate, which discharges the air in the protective cover 7 to the air outlet duct 10 and the air guide plate 13 in sequence. This is conducive to promoting air flow and dust flow to the dust collector bag 6, and promotes dust adsorption on the dust collector bag 6. At the same time, the gas is discharged through the air guide plate 13.

[0049] As the gas is discharged through the air guide plate 13, the flowing gas will blow the blades 15 to rotate. During the rotation of the blades 15, the striking ball 16 will repeatedly strike the bottom surface of the guide plate 3, which will help promote the vibration of the bottom surface of the guide plate 3. On the one hand, this will facilitate the feeding of materials, and on the other hand, it will help prevent the materials from caking on the inner wall of the guide plate 3, which would affect the cooling effect of the materials.

[0050] During the process of gas being discharged through the air guide plate 13, the heat sink 17 helps to cool the gas flowing inside the air guide plate 13 and the bottom surface of the guide plate 3, thus reducing the temperature of the material. On the other hand, the temperature of the material is conducted to the air guide plate 13 through the guide plate 3, and the heat sink 17 helps to cool the air guide plate 13, which in turn further helps to reduce the temperature of the material. With the air guide groove 18 and the guide plate 19, during the process of gas flowing through the air outlet duct 2 10 to the air guide plate 13, some gas will be blown towards the heat sink 17 through the air guide groove 18, which helps to dissipate heat from the heat sink 17 and further helps to reduce the temperature of the material.

[0051] As the material slides down through the guide plate 3, the heat absorption cover 21 absorbs the heat in the material during the sliding process, promoting the reduction of the material temperature. At the same time, the heat absorption cover 21 is set in an arc shell structure, which helps to increase the contact area between the heat absorption cover 21 and the material, which helps to improve the heat absorption efficiency, and thus helps to reduce the material temperature.

[0052] As the material slides down the guide plate 3, the electromagnetic three-way valve 25 controls the connection between the liquid inlet pipe 23 and the water pump 24. The water pump 24 starts and pumps the water in the water tank 30 into the cooling pipe 20 through the return pipe 32. The water flows in the cooling pipe 20, cooling the heat absorption cover 21 on one hand and the bottom surface of the guide plate 3 on the other. Finally, the water flows back into the water tank 30 through the liquid outlet pipe 22 and the return pipe 32.

[0053] When it is necessary to clean the inner bottom surface of the guide plate 3 and the heat absorption cover 21, the electromagnetic three-way valve 25 controls the water pump 24 to connect with the conveying pipe 26. The water pump 24 pumps the water in the water tank 30 into the conveying pipe 26 and sprays it from the spray nozzle 28 onto the inner bottom surface of the guide plate 3 and the heat absorption cover 21. This helps to prevent the material from caking and solidifying on the guide plate 3 and the heat absorption cover 21, which would affect the cooling of the material.
