Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying, and particularly relates to a water-cooling structure, a water-cooling system and a rotary valve of a rotary valve. Background Art

[0002] In the material conveying links of many industries such as metallurgy, cement, and mines, valves are often required to quantitatively convey materials to meet the production process requirements. The rotary valve is one of the quantitative conveying valves widely used in the market. The rotary valve is also called a rotary feeder and is applied to the conveying system of solid materials (such as powder, granular materials, and powder-particle mixtures).

[0003] With the upgrading of production processes, some production lines require production under high-temperature, high-pressure, and flammable gas conditions. The product materials are not only at high temperatures (above 600°C, and in a few production lines above 1000°C), but also the materials cannot be directly exposed to gas environments with oxidizing effects such as air. This requires that the rotary valves on the production line can not only withstand high temperatures and high pressures, but also the equipment performance must be safe and reliable. In case of any abnormal situation, it must respond and handle quickly.

[0004] The existing rotary valves for high-temperature working conditions are mostly divided into two types: one is made of materials with better heat resistance to achieve high-temperature resistance. In the case of requiring high-temperature resistance without pressure, the temperature resistance can exceed 600°C. However, if it is required to withstand high temperatures and high pressures simultaneously, the temperature resistance generally cannot exceed 600°C; the other is to adopt a water-cooling scheme, but the water-cooling mostly adopts a relatively rough cooling method, such as a single water path for the entire valve body to pass through the cold. On the one hand, there are often dead zones in the cooling path, and the resistance loss of the cooling path is large, resulting in poor effects when the temperature exceeds 600°C. On the other hand, it cannot be cooled finely according to the characteristics of the material passing through the valve body, and the high-temperature resistance performance is poor, and the reliability is greatly reduced when used in high-temperature and high-pressure working conditions.

The water-cooling structure includes 13 cooling water circuits. Among them, 1 transmission-shaft cooling water circuit 201 is arranged inside the transmission shaft 20; 1 working-side flange cooling water circuit 202 and 1 transmission-side flange cooling water circuit 204 are respectively arranged on the working-side flange 50 and the transmission-side flange 30; 1 working-side stuffing box cooling water circuit 203 and 1 transmission-side stuffing box cooling water circuit 205 are respectively arranged on the working-side stuffing box 60 and the transmission-side stuffing box 40; 8 housing cooling water circuits are distributed in partial areas inside the rotary valve housing 10.

[0077] Specifically, the rotary valve 100 includes a rotary valve housing 10, a transmission shaft 20 rotatably arranged inside the rotary valve housing 10. A rotor 80 is fixedly sleeved on the transmission shaft 20. The transmission shaft 20 is supported on a support plate connected to respective flanges through transmission-side and working-side bearings and bearing seats, and is driven to rotate by a driving assembly 70. The driving assembly 70 includes a driving motor 71 and a coupling 72. The end of the transmission shaft 20 is connected to the driving assembly 70. One side of the rotary valve housing 10 close to the end of the transmission shaft 20 is the transmission side, and one side close to the front end of the transmission shaft 20 is the working side. A material inlet 11 is opened at the upper part of the rotary valve housing 10. The material inlet 11 is eccentrically arranged relative to the center of the rotary valve 100, which is beneficial to the transportation of solid particle materials. An outlet 12 is arranged at the lower part of the rotary valve housing 10 for discharging materials; a cooling gas inlet 13 is arranged at the upper part of the non-eccentric side of the rotary valve housing 10. The cooling gas inlet 13 is arranged on the side opposite to the material inlet 11. A maintenance hole 14 is also arranged at the material inlet 11 section of the rotary valve 100. A transmission-side flange 30 and a transmission-side stuffing box 40 are arranged on the transmission side of the rotary valve housing 10, and a working-side flange 50 and a working-side stuffing box 60 are arranged on the working side of the rotary valve housing 10.

[0078] The water-cooling structure of the rotary valve includes 13 cooling water channels, which are arranged in zones on the rotary valve 100. Among them, 8 shell cooling water channels are distributed in the rotary valve housing 10 in zones to jointly cool and protect the rotary valve housing 10; 1 drive shaft cooling water channel 201 is arranged inside the drive shaft 20 to cool and protect the drive shaft 20; 1 working-side flange cooling water channel 202 is arranged on the working-side flange 50 to cool and protect the working-side flange 50; 1 drive-side flange cooling water channel is arranged on the drive-side flange 30 to cool and protect the drive-side flange 30; 1 working-side stuffing box cooling water channel 203 is arranged on the working-side stuffing box 60 to cool and protect the stuffing seal area; 1 drive-side stuffing box cooling water channel 205 is arranged on the drive-side stuffing box 40 to cool and protect the stuffing seal area.

[0079] Refer to Figure 3 , in some embodiments, an axially arranged drive shaft inner hole 21 is provided inside the drive shaft 20. A sleeve 22 is inserted into the drive shaft inner hole 21. The front end of the sleeve 22 is connected to a rotary joint 23. A gap is provided between the sleeve 22 and the drive shaft inner hole 21. The rotary joint 23 is provided with a drive shaft water inlet 201a and a drive shaft water outlet 201b that communicate with the drive shaft cooling water channel 201. The drive shaft cooling water channel 201 is formed by the drive shaft inner hole 21, the sleeve 22, and the rotary joint 23. Specifically, cooling water enters the inside of the sleeve 22 from the drive shaft water inlet 201a, then flows out into the drive shaft inner hole 21, and flows in the gap between the sleeve 22 and the drive shaft inner hole 21 until it flows out from the drive shaft water outlet 201b. This design ensures that the cooling water can directly and evenly contact the inner wall of the drive shaft 20, thereby achieving efficient heat conduction. The contact area between the cooling water and the material of the drive shaft 20 is effectively increased, further improving the heat dissipation efficiency; among them, the drive shaft water inlet 201a is arranged at the front end of the rotary joint 23, and the drive shaft water outlet 201b is arranged at the side of the rotary joint 23. The designs of the sleeve 22 and the rotary joint 23 are ingeniously built inside the drive shaft 20 without occupying extra space, making the structure more compact and facilitating the realization of complex transmission and cooling functions in a limited space. In this way, through the drive shaft cooling water channel 201, the thermal stress generated by the drive shaft 20 during operation can be significantly reduced, thereby extending the service life of the drive shaft 20 and its related components.

[0080] Continue to refer to Figure 2 and Figure 3, in the above embodiment, the working side flange cooling water channel 202 is located inside the working side flange 50. The working side flange 50 is provided with a first flange water channel inlet 202a and a first flange water channel outlet 202b that communicate with the working side flange cooling water channel 202. The first flange water channel inlet 202a is located at the lower center of the working side flange cooling water channel 202, and the first flange water channel outlet 202b is located at the upper center of the working side flange cooling water channel 202. Specifically, the working side flange cooling water channel 202 is annular. Cooling water enters from the first flange water channel inlet 202a at the lower part, and can flow evenly through the working side flange cooling water channel 202 from bottom to top, and flows out from the first flange water channel outlet 202b at the upper part, effectively avoiding the phenomena of local overheating or uneven cooling, thereby improving the cooling efficiency; through sufficient heat exchange between the cooling water and the working side flange 50, it is beneficial to reduce the risk of deformation or cracks of the working side flange 50 caused by thermal stress, making the working side flange 50 more stable and reliable when bearing working pressure and temperature changes.

[0081] Refer to Figure 3 , in the above embodiment, the drive side flange cooling water channel 204 is located inside the drive side flange 30. The drive side flange 30 is provided with a second flange water channel inlet 204a and a second flange water channel outlet 204b that communicate with the drive side flange cooling water channel 204. The second flange water channel inlet 204a is located at the lower center of the drive side flange cooling water channel 204, and the second flange water channel outlet 204b is located at the upper center of the drive side flange cooling water channel 204. Specifically, the drive side flange cooling water channel 204 is annular. Cooling water enters from the second flange water channel inlet 204a at the lower part, and can flow evenly through the drive side flange cooling water channel 204 from bottom to top, and flows out from the second flange water channel outlet 204b at the upper part, effectively avoiding the phenomena of local overheating or uneven cooling, thereby improving the cooling efficiency; through sufficient heat exchange between the cooling water and the drive side flange 30, it is beneficial to reduce the risk of deformation or cracks of the drive side flange 30 caused by thermal stress, making the drive side flange 30 more stable and reliable when bearing working pressure and temperature changes.

The working side stuffing box 60 is provided with a first stuffing box water passage inlet 203a and a first stuffing box water passage outlet 203b that communicate with the working side stuffing box cooling water passage 203. The first stuffing box water passage inlet 203a is located at the lower center of the working side stuffing box cooling water passage 203, and the first stuffing box water passage outlet 203b is located at the upper center of the working side stuffing box cooling water passage 203. Specifically, the working side stuffing box cooling water passage 203 is annular. Cooling water enters from the first stuffing box water passage inlet 203a at the bottom and can flow evenly through the working side stuffing box cooling water passage 203 from bottom to top and flows out from the first stuffing box water passage outlet 203b at the upper part. This design ensures that the cooling water can fully contact and carry away the heat generated inside the working side stuffing box 60, thereby effectively reducing the working temperature of the working side stuffing box 60 and its internal components, avoiding the phenomenon of local overheating, and ensuring the stable operation of all parts of the equipment. The evenly distributed working side stuffing box cooling water passage 203 can significantly reduce the thermal stress caused by temperature changes and helps to extend the service life of the working side stuffing box 60.

[0083] Continue to refer to Figure 3 , in the above embodiments, the drive side stuffing box cooling water passage 205 is located inside the drive side stuffing box 40. The drive side stuffing box 40 is provided with a second stuffing box water passage inlet 205a and a second stuffing box water passage outlet 205b that communicate with the drive side stuffing box cooling water passage 205. The second stuffing box water passage inlet 205a is located at the lower center of the drive side stuffing box cooling water passage 205, and the second stuffing box water passage outlet 205b is located at the upper center of the drive side stuffing box cooling water passage 205. Specifically, the drive side stuffing box cooling water passage 205 is annular. Cooling water enters from the second stuffing box water passage inlet 205a at the bottom and can flow evenly through the drive side stuffing box cooling water passage 205 from bottom to top and flows out from the second stuffing box water passage outlet 205b at the upper part. This design ensures that the cooling water can fully contact and carry away the heat generated inside the drive side stuffing box 40, thereby effectively reducing the working temperature of the drive side stuffing box 40 and its internal components, avoiding the phenomenon of local overheating, and ensuring the stable operation of all parts of the equipment. The evenly distributed drive side stuffing box cooling water passage 205 can significantly reduce the thermal stress caused by temperature changes and helps to extend the service life of the drive side stuffing box 40.

[0084] Refer to Figure 1 and Figure 5, in some embodiments, each of the housing cooling waterways has a housing waterway inlet and a housing waterway outlet. The housing waterway inlet is located at the lower center of the housing cooling waterway, and the housing waterway outlet is located at the upper center of the housing cooling waterway. Thus, the housing waterway inlet is below the housing waterway outlet, and the cooling water enters from the housing waterway inlet and flows out from the housing waterway outlet to cool the corresponding parts of the rotary valve housing 10. Since the cooling water starts to flow from the lower part of the housing cooling waterway and gradually diffuses upward, this layout ensures that relatively uniform cooling can be achieved for all parts of the rotary valve housing 10. During the process of the cooling water flowing from bottom to top, the temperature gradually rises and finally is discharged from the housing waterway outlet. This design enables the cooling water to fully absorb heat during the flowing process, thereby improving the energy efficiency of cooling. The position design of the housing waterway inlet and the housing waterway outlet facilitates daily maintenance and repair.

[0085] Continue to refer to Figure 1 and Figure 5, in the above embodiment, the eight housing cooling waterways are respectively the first housing cooling waterway 206, the second housing cooling waterway 207, the third housing cooling waterway 208, the fourth housing cooling waterway 209, the fifth housing cooling waterway 210, the sixth housing cooling waterway 211, the seventh housing cooling waterway 212 and the eighth housing cooling waterway 213. The first housing cooling waterway 206, the second housing cooling waterway 207, the third housing cooling waterway 208 and the fourth housing cooling waterway 209 are on the same side as the maintenance hole 14 of the rotary valve 100. The fifth housing cooling waterway 210, the sixth housing cooling waterway 211, the seventh housing cooling waterway 212 and the eighth housing cooling waterway 213 are on the same side as the cooling air inlet 13 of the rotary valve 100. The maintenance hole 14 and the cooling air inlet 13 are arranged on different sides. Specifically, by partitioning and arranging eight independent housing cooling waterways, it is convenient to perform independent cooling control for each area. This partition design can flexibly adjust the cooling flow rate and temperature of each housing cooling waterway according to the heat generation situation in different areas, achieving a more precise cooling effect. Through partition cooling, the heat distribution in the rotary valve housing 10 can be managed more effectively, avoiding local overheating or insufficient cooling, thereby improving the overall heat exchange efficiency. Each housing cooling waterway cools a part of the housing, ensuring the uniformity of the cooling effect, helping to reduce the thermal stress caused by the temperature gradient, and protecting the structural integrity of the rotary valve housing 10. The setting of multiple housing cooling waterways increases redundancy. Each housing cooling waterway can be regarded as an independent module, facilitating separate maintenance and repair work. Even if a certain housing cooling waterway fails, the other cooling waterways can still continue to work, ensuring that the rotary valve housing 10 can still operate normally for a period of time. At this time, the faulty waterway can be quickly repaired online without immediately causing the rotary valve to stop due to the waterway failure and causing losses to the entire production line.

[0086] Refer to Figure 1 and Figure 3, in the above embodiment, the first housing cooling water passage 206 is located at the upper part of the working side of the rotary valve 100 and on the same side as the inspection hole 14, and is formed by enclosing the rotary valve housing 10, the water passage outer shell plate 15, the first bent partition plate 171, the first vertical partition plate 181, the second vertical partition plate 182 and the first horizontal partition plate 191; a part of the water passage outer shell plate 15 covers the rotary valve housing 10, the first bent partition plate 171 is located between the water passage outer shell plate 15 and the rotary valve housing 10 at the upper part of the working side, the first vertical partition plate 181 is located between the middle of the feeding port 11 of the rotary valve 100 and the inspection hole 14, the second vertical partition plate 182 is located between the inspection hole 14 and the discharging port 12 of the rotary valve 100, and the second vertical partition plate 182 and the first vertical partition plate 181 are in the same plane, and the first horizontal partition plate 191 is located between the middle of the working side flange 50 and the second vertical partition plate 182. Specifically, the first housing cooling water passage 206 has a first housing water passage inlet 206a and a first housing water passage outlet 206b. The first housing water passage inlet 206a is close to the first horizontal partition plate 191, and the first housing water passage outlet 206b is close to the feeding port 11 of the rotary valve 100. Cooling water enters from the first housing water passage inlet 206a at the lower part, flows through the first housing cooling water passage 206 and flows out from the first housing water passage outlet 206b at the upper part; through the first housing cooling water passage 206, the flow path of the cooling water is optimized, so that the cooling water can fully contact the hot surface of the rotary valve housing 10.

A first pressure gauge 308 and a first thermometer 309 are arranged on the main inlet pipe 302, and first control valves 307 are arranged upstream and downstream of the first pressure gauge 308 and the first thermometer 309; specifically, since the cooling water sources of the respective cooling branch pipes 304 are the same, and the inlet water pressure and temperature are the same, a first pressure gauge 308 and a first thermometer 309 are arranged on the main inlet pipe 302, and first control valves 307 are arranged upstream and downstream of the first pressure gauge 308 and the first thermometer 309, which is convenient for the detection and maintenance of the first pressure gauge 308 and the first thermometer 309.

[0098] In order for the water cooling system 300 to achieve refined control, a first flowmeter 311 is provided on the water inlet branch pipe 304a of each cooling branch pipe 304. A second control valve 310 is provided upstream of each first flowmeter 311, and a first control valve 307 is provided downstream, so that the flow rate of each water inlet branch pipe 304a can be independently adjusted.

[0100] Based on the same concept, the present application also provides a rotary valve 100 (refer to Figure 1 ), including the water cooling structure of the rotary valve as described above.

[0101] Embodiment 2: In another embodiment, refer to Figure 7 , which is different from Embodiment 1 in that: the water cooling system 300 is provided with 7 cooling branch pipes 304. Among them, the transmission shaft cooling water path 201 is separately connected to the first cooling branch pipe 304; the working side flange cooling water path 202 is in series with the working side stuffing box cooling water path 203 and is connected to the second cooling branch pipe 304; the drive side flange cooling water path 204 is in series with the drive side stuffing box cooling water path 205 and is connected to the third cooling branch pipe 304; the first housing cooling water path 206 is in series with the third housing cooling water path 208 and is connected to the fourth cooling branch pipe 304; the second housing cooling water path 207 is in series with the fourth housing cooling water path 209 and is connected to the fifth cooling branch pipe 304; the fifth housing cooling water path 210 is in series with the seventh housing cooling water path 212 and is connected to the sixth cooling branch pipe 304; the sixth housing cooling water path 211 is in series with the eighth housing cooling water path 213 and is connected to the seventh cooling branch pipe 304.

[0102] Specifically, other waterway partition methods can be formed by appropriate changes. For example, by canceling the first transverse partition 191, the first housing cooling waterway 206 and the third cooling waterway can be connected in series to form one cooling waterway; by canceling the second transverse partition 192, the second housing cooling waterway 207 and the fourth housing cooling waterway 209 can be connected in series to form one cooling waterway; by canceling the third transverse partition 193, the fifth housing cooling waterway 210 and the seventh housing cooling waterway 212 can be connected in series to form one cooling waterway; by canceling the fourth transverse partition 194, the sixth housing cooling waterway 211 and the eighth housing cooling waterway 213 can be connected in series to form one cooling waterway.

[0103] According to the working conditions of the production line, the 13 cooling waterways distributed on the rotary valve 100 are set as 7 cooling branch pipes 304 through series connection. After the cooling water is output from the cooling water circulation unit 301, it sequentially passes through the water inlet main pipe 302, the water inlet tank 303, the water inlet branch pipe 304a of the cooling branch pipe 304, each cooling waterway of the rotary valve 100, the water outlet branch pipe 304b of the cooling branch pipe 304, the water outlet tank 305, and the water outlet main pipe 306, and then enters the cooling water circulation unit 301 for treatment, thereby forming a closed-loop water cooling system 300 to cool the rotary valve 100.

[0104] In the case where the working conditions of the production line are not extremely harsh and high temperature, Embodiment 2 gives a relatively simple water cooling system 300 compared to Embodiment 1, changing from 13 cooling branch pipes 304 to 7 cooling branch pipes 304, which simplifies the configuration of the water cooling system 300. It should be noted that through different series or parallel connection schemes of each cooling waterway of the rotary valve 100, various configurations of water cooling branches can be realized, which will not be listed one by one.
