Description

Technical Field

[0001] This application relates to the field of roller cooling equipment, and in particular to a cooling device for rollers in a pyrolysis furnace. Background Technology

[0002] During the operation of a pyrolysis furnace, the support rollers play a crucial supporting and transmission role. However, due to the high-temperature environment inside the pyrolysis furnace and the continuous operation of the support rollers for extended periods, they rapidly absorb a large amount of heat, causing their temperature to rise sharply. Excessive roller temperature can significantly impact the normal operation of the pyrolysis furnace and the service life of the support rollers. On the one hand, high temperatures can significantly reduce the mechanical properties of the support rollers, including decreased hardness and weakened strength. This not only shortens the service life of the support rollers but may also lead to dangerous situations such as deformation or even breakage during operation. On the other hand, excessively high temperatures can worsen the lubrication effect of the support rollers, causing the lubricating grease to deteriorate or evaporate, thereby increasing friction between the support rollers and journals, as well as between the support rollers and rails. This accelerates the wear of the support rollers and related components, reducing production efficiency and product quality.

[0003] The existing cooling methods for pyrolysis furnace support rollers have many shortcomings. Some common cooling methods, such as simple air cooling, although relatively simple in structure, have very limited cooling effect and cannot meet the heat dissipation requirements of pyrolysis furnace support rollers in high-temperature environments. While water cooling can provide a better cooling effect to a certain extent, it often has some problems, such as uneven water flow distribution, which leads to insufficient local cooling of the support rollers.

[0004] To address this issue, a cooling device for pyrolysis furnace support rollers has been invented to solve the problem of excessively high temperatures during the operation of current pyrolysis furnace support rollers. Utility Model Content

[0005] To address the problem of excessively high temperatures during the operation of current pyrolysis furnace support rollers, this application provides a cooling device for pyrolysis furnace support rollers.

[0007] Optionally, the first cooling mechanism includes several annular cooling pipes opened inside the support roller. A first cooling water inlet communicating with the annular cooling pipes is opened on one side of the support roller, and a first cooling water outlet communicating with the annular cooling pipes is opened on the other side of the support roller. Cooling water enters through the first cooling water inlet, flows through the annular cooling pipes, and is discharged from the first cooling water outlet. A liquid inlet chamber is provided on one side of the fixed cavity, and a liquid inlet pipe is connected and fixed to the bottom of the liquid inlet chamber. A liquid outlet chamber is provided on the other side of the fixed cavity, and a liquid outlet pipe is connected and fixed to the bottom of the liquid outlet chamber.

[0008] Optionally, the second cooling mechanism includes a connecting frame, which is fixed inside the fixed cavity. The connecting frame is provided with a plurality of cooling water nozzles, which can spray cooling water onto the surface of the support roller.

[0009] Optionally, the air-cooling mechanism includes an air intake chamber, which is fixed in a fixed cavity.

Therefore, they should not be construed as limiting the present invention.

[0022] Reference Figure 1 , Figure 4 One embodiment shown is: a cooling device for a pyrolysis furnace support roller: including a fixed base 1, wherein a support roller 2 is rotatably connected to the middle of the fixed base 1, a fixed cavity 3 is provided on the fixed base 1, the support roller 2 is disposed in the middle of the fixed cavity 3, a first cooling mechanism 4 is provided in the support roller 2, a second cooling mechanism 5 is provided in the fixed cavity 3 to cool the surface of the support roller 2, and an air cooling mechanism 6 is provided in the fixed cavity 3 to perform air cooling on the support roller 2;

[0023] The overall structure of this device mainly includes a fixed base 1, a support roller 2, a first cooling mechanism 4, a second cooling mechanism 5, and an air-cooling mechanism 6. The fixed base 1 serves as the basic support component of the entire device, with the support roller 2 rotatably connected to its center. A fixed cavity 3 is provided on the fixed base 1, and the support roller 2 is located in the center of the fixed cavity 3. The first cooling mechanism 4 is installed inside the support roller 2, and the second cooling mechanism 5 and the air-cooling mechanism 6 are respectively installed in the fixed cavity 3 to achieve all-round cooling of the support roller 2.

[0024] The implementation principle is as follows: By setting an annular cooling pipe 7 inside the support roller 2, a first cooling mechanism 4 is formed, allowing cooling water to circulate directly inside the support roller 2 and fully exchange heat with it, quickly removing the heat generated inside the support roller 2 and achieving efficient cooling from the inside; the cooling water nozzle 16 in the second cooling mechanism 5 can spray cooling water onto the surface of the support roller 2, directly cooling the outer surface of the support roller 2, further enhancing the cooling effect. This combination of internal and external cooling greatly improves the overall cooling efficiency and can quickly and effectively reduce the temperature of the support roller 2; the rotating fan 18 in the air-cooling mechanism 6 can blow air onto the surface of the support roller 2, accelerating the airflow on the surface of the support roller 2 and promoting heat dissipation. In conjunction with the water cooling method, it further enhances the cooling effect and achieves the purpose of rapid cooling.

[0025] Reference Figure 5One embodiment shown is as follows: Multiple annular cooling pipes 7 are provided inside the support roller 2. A first cooling water inlet 8, connected to the annular cooling pipes 7, is located on one side of the support roller 2, and a first cooling water outlet 9, also connected to the annular cooling pipes 7, is located on the other side. In actual operation, cooling water enters the annular cooling pipes 7 from the first cooling water inlet 8, exchanges heat with the support roller 2 during its flow through the annular cooling pipes 7, absorbs heat from inside the support roller 2, and then exits from the first cooling water outlet 9. A liquid inlet chamber 10 is fixedly connected to one side of the fixed cavity 3, and a liquid inlet pipe 11 is fixedly connected to the bottom of the liquid inlet chamber 10 for introducing external cooling water into the annular cooling pipes 7 of the support roller 2. A drain chamber 12 is fixedly connected to the other side of the fixed cavity 3, and a drain pipe 13 is fixedly connected to the bottom of the drain chamber 12 for discharging the cooled water after heat exchange. The support roller 2 has multiple annular cooling pipes 7 on both sides of the support roller 2. The support plate 14 is connected, and the liquid inlet chamber 10 and the liquid outlet chamber 12 can rotate relative to the support plate 14 on their respective sides. This design ensures the normal rotation of the support roller 2 and also enables the smooth entry and exit of cooling water. Implementation principle: When the pyrolysis furnace is running, the support roller 2 generates heat due to contact with the internal environment of the pyrolysis furnace and its own rotational friction. At this time, cooling water is injected into the liquid inlet chamber 10 from the outside through the liquid inlet pipe 11. The cooling water enters the annular cooling pipe 7 inside the support roller 2. Since the annular cooling pipe 7 is in close contact with the support roller 2, heat is transferred from the support roller 2 to the cooling water. As the cooling water flows in the annular cooling pipe 7, it continuously absorbs the heat inside the support roller 2, causing its temperature to gradually decrease. The cooling water that has absorbed the heat finally flows out through the first cooling water outlet 9 to the liquid outlet chamber 12, and then is discharged through the liquid outlet pipe 13, thereby achieving the cooling and temperature reduction of the support roller 2.

[0026] Reference Figure 4 One embodiment shown is as follows: The connecting frame 15 is fixed at the bottom of the fixed cavity 3. Multiple cooling water nozzles 16 are provided on the connecting frame 15. When the device is running, cooling water enters the connecting frame 15 through the coolant inlet pipe 21, and then sprays cooling water from the cooling water nozzles 16 onto the surface of the support roller 2, directly cooling the outer surface of the support roller 2, further enhancing the cooling effect.

[0027] The implementation principle is as follows: coolant enters pipe 21 to transport external cooling water to the connecting frame 15. Under pressure, the cooling water is sprayed out from the cooling water nozzle 16 on the connecting frame 15, forming a fine water mist or water stream, which is directly sprayed onto the surface of the support roller 2. Since the surface temperature of the support roller 2 is high, the cooling water will quickly absorb heat when it comes into contact with the surface of the support roller 2, and undergo heat exchange processes such as vaporization or heating, thereby taking away the heat from the surface of the support roller 2 and achieving cooling of the surface of the support roller 2.

[0028] Reference Figure 2 , Figure 4One embodiment shown is as follows: The air-cooling mechanism 6 includes an air intake chamber 17, which is fixed in the fixed cavity 3. A rotating fan 18 is fixed in the air intake chamber 17 by bolts. The rotating fan 18 can blow air onto the surface of the support roller 2, accelerate the air flow on the surface of the support roller 2, and promote heat dissipation. In combination with the water cooling method, it can improve the cooling effect. The surface of the support roller 2 is provided with multiple annular grooves 19 to facilitate air flow on the surface of the support roller 2. A long strip of water-absorbing sponge 20 is fixedly connected to the bottom of the air intake chamber 17 and arranged vertically. The upper side of the water-absorbing sponge 20 is in contact with the support roller 2. The water-absorbing sponge 20 can absorb the moisture on the surface of the support roller 2 and prevent the moisture from accumulating on the surface of the support roller 2. At the same time, as the moisture in the water-absorbing sponge 20 increases, the excess moisture drips to the bottom of the water-absorbing sponge 20 under the action of gravity, which can also play a certain wiping role, keep the surface of the support roller 2 clean, and facilitate heat dissipation and normal operation of the support roller 2.

[0029] The implementation principle is as follows: The rotating fan 18 in the air-cooling mechanism 6 starts to rotate under the drive of the motor and other drive devices. When the rotating fan 18 rotates, it generates airflow, which blows towards the surface of the support roller 2, accelerating the airflow speed on the surface of the support roller 2. According to the principle of heat transfer, accelerating the airflow speed can enhance the efficiency of heat transfer from the surface of the support roller 2 to the surrounding environment, thereby promoting the dissipation of heat from the surface of the support roller 2 and playing the role of air cooling. At the same time, the water-absorbing sponge 20 at the bottom of the air inlet chamber 17 contacts the support roller 2. On the one hand, it can absorb the moisture remaining on the surface of the support roller 2 due to water cooling, preventing moisture accumulation from affecting the operation and heat dissipation of the support roller 2. On the other hand, during the contact process with the support roller 2, the water-absorbing sponge 20 can also dissipate moisture into the air through its own capillary action, further promoting heat dissipation and keeping the surface of the support roller 2 relatively dry and clean, which is beneficial to improving the air cooling effect and the service life of the support roller 2.

[0030] Reference Figure 4 One embodiment shown is as follows: a coolant inlet pipe 21 is fixedly connected to the bottom of the fixed cavity 3. The coolant inlet pipe 21 is connected to the connecting frame 15 and the liquid inlet pipe 11 respectively, and is used to provide cooling water to the liquid inlet chamber 10 of the second cooling mechanism 5 and the first cooling mechanism 4. A drain trough 22 is fixedly connected to the bottom of the fixed cavity 3. A coolant outlet pipe 23 is fixedly connected in the drain trough 22. The coolant outlet pipe 23 is connected to the drain pipe 13 respectively, and is used to discharge the cooling water after heat exchange.

[0031] The working principle of this device is as follows: During the operation of the pyrolysis furnace, the temperature of the support roller 2 will gradually rise. When the temperature rises to a certain level, the cooling device will start to work. First, the external cooling water enters the inlet chamber 10 in the fixed chamber 3 through the inlet pipe 11, and then flows into the annular cooling pipe 7 inside the support roller 2 to cool the inside of the support roller 2. After absorbing heat, the cooling water is discharged from the first cooling water outlet 9 to the drain chamber 12, and then discharged through the drain pipe 13.

[0032] At the same time, the coolant enters the pipe 21 to transport the cooling water to the connecting frame 15, and the cooling water is sprayed onto the surface of the support roller 2 by the cooling water nozzle 16 to directly cool and reduce the temperature of the support roller 2.

[0033] In addition, the rotating fan 18 in the air-cooling mechanism 6 starts and blows air onto the surface of the support roller 2, accelerating the dissipation of heat from the surface of the support roller 2. Through the cooling effect of the first cooling mechanism 4 from inside the support roller 2, the second cooling mechanism 5 from the surface of the support roller 2, and the air-cooling mechanism 6 on the surface of the support roller 2, the three work together to achieve rapid and efficient cooling of the support roller 2, so that the temperature of the support roller 2 is always kept within a suitable range, ensuring the normal and stable operation of the pyrolysis furnace and the service life and performance of the support roller 2.

[0034] The working principle of this device has been explained through the above embodiments. These embodiments merely illustrate several implementation methods of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
