Description

Technical Field

[0001] This utility model relates to the field of steel coil storage technology, specifically to a finned heating device for reducing the risk of condensation on steel coils in storage areas. Background Technology

[0002] Every year in March, November, and during the plum rain season, the high humidity and sudden temperature changes cause condensation to easily form on the steel coils in the factory's steel coil storage area. Water droplets seep into the steel coils through the gaps in the coils, causing white rust.

[0003] For example, Chinese patent CN211454654U describes an anti-condensation device for galvanized and painted steel coils. The galvanized and painted steel coils are stored in a storage area equipped with a blower. An ambient temperature sensor and an ambient humidity sensor are installed in the storage area. A steel coil temperature sensor is installed on the surface of the galvanized and painted steel coils located in the storage area. Each sensor outputs a corresponding signal to a temperature and humidity server. The temperature and humidity server is communicatively connected to a data acquisition service controller, which sends an anti-condensation alarm signal to an external server. Simultaneously, the temperature and humidity server is equipped with an audible and visual alarm driver that communicates with an external alarm, including an audible and visual alarm installed in the monitoring room of the storage area. This invention effectively eliminates the problem of steel coil condensation and can be used without any modification to the blower, further reducing implementation costs.

[0004] While the above structure can eliminate the problem of condensation on steel coils, it requires heating the storage area, which involves a large heating space and high energy consumption.

[0005] Based on this, this utility model designs a finned heating device to reduce the risk of condensation on steel coils in storage areas in order to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a finned heating device to reduce the risk of condensation on steel coils in storage areas.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A finned heating device for reducing the risk of condensation on steel coils in a storage area includes multiple sets of heating components arranged at equal intervals.

[0009] The heating assembly includes an inlet pipe, a tee, a diverter pipe, a return pipe, and modular heating components. The input and output ends of the tee are respectively connected to the inlet pipe and the two diverter pipes. Multiple modular heating components are symmetrically and equally spaced. The modular heating components are fixedly installed on the opposite side walls of the two diverter pipes. The end of the modular heating component away from the diverter pipe is connected to the return pipe. The inlet pipe and the return pipe are respectively fixedly connected to the output and input ends of the heating equipment.

[0010] A U-shaped support plate is provided on the outer wall of the diversion pipe. Supporting inclined blocks corresponding to the modular heating components are fixedly connected at equal intervals on the U-shaped support plate, and the left and right adjacent support inclined blocks are set opposite each other.

[0011] The support ramp is connected to a gate valve control structure for communicating with the modular heating component at the corresponding position. The gate valve control structure is connected to the control end of the modular heating component. When a steel coil is placed on the support ramp, the gate valve control structure connects the modular heating component with the diversion pipe. When no steel coil is placed on the support ramp, the gate valve control structure isolates and closes the modular heating component from the diversion pipe.

[0012] Furthermore, the modular heating assembly includes a first horizontal tube, fins, a one-way valve, a straight tube, a gate valve, and a second horizontal tube. The gate valve is fixedly installed at the end of the second horizontal tube near the diversion tube and is fixedly connected to the gate valve control structure. The second horizontal tube is fixedly connected to the diversion tube. Straight tubes are fixedly connected at equal intervals at the front and rear ends of the second horizontal tube. The end of the straight tube away from the second horizontal tube is fixedly connected to the first horizontal tube. The first horizontal tube is fixedly connected to the return pipe. A one-way valve is installed at the end of the one-way valve near the return pipe and is connected to the return pipe. Multiple sets of fins are fixedly installed at equal intervals on the straight tube. When a steel coil is placed on the support inclined block, the gate valve control structure opens the gate valve, and the modular heating assembly is connected to the diversion tube. When no steel coil is placed on the support inclined block, the gate valve control structure closes the gate valve, and the modular heating assembly is isolated and closed from the diversion tube.

[0013] Furthermore, the gate valve is located between the branch pipe and the straight pipe near the branch pipe;

[0014] The check valve is located between the return pipe and the straight pipe near the return pipe.

[0015] Furthermore, the gate valve control structure includes a follower component, a transmission component, and a connecting component. The support inclined block has an L-shaped groove. The follower component is fixedly installed at the bottom of the vertical part of the L-shaped groove. The two ends of the transmission component are movably connected to the follower component and the connecting component, respectively. The transmission component is rotatably connected to the horizontal part of the L-shaped groove. The connecting component is fixedly connected to the valve stem of the gate valve. When no steel coil is placed on the support inclined block, the top of the follower component is higher than the top of the support inclined block, and the valve stem of the gate valve is at the bottom. When a steel coil is placed on the support inclined block, the top of the follower component is lower than the top of the horizontal part of the L-shaped groove, and the valve stem of the gate valve is at the top.

[0016] Furthermore, the follower assembly includes a convex plate, a sliding sleeve, an outer cylinder, and a spring. The lower end of the convex plate is slidably connected to the inner wall of the vertical part of the L-shaped groove. The bottom of the convex plate is fixedly connected to the top of the sliding sleeve and the spring. The inner wall of the sliding sleeve is slidably connected to the outer wall of the outer cylinder. The bottom of the outer cylinder is fixedly connected to the bottom of the vertical part of the L-shaped groove. The spring is located inside the outer cylinder. The convex plate is connected to the transmission assembly. When no steel coil is placed on the support inclined block, the top of the convex plate is higher than the top of the support inclined block, and the valve stem of the gate valve is located at the lowest end. When a steel coil is placed on the support inclined block, the top of the convex plate is lower than the top of the horizontal part of the L-shaped groove, and the valve stem of the gate valve is located at the highest end.

[0017] Furthermore, the transmission assembly includes a first slide rod, a connecting shaft, a second slide rod, and a rotating rod. A transverse groove is provided at the lower end of the convex plate. The first slide rod is slidably connected to the inner wall of the transverse groove. The first slide rod and the second slide rod are respectively fixedly installed at both ends of the rotating rod. The middle end of the rotating rod is rotatably connected to the connecting shaft, and the connecting shaft is rotatably connected to the transverse part of the L-shaped groove. The second slide rod is movably connected to the connecting assembly.

[0018] Furthermore, the connecting component includes a square frame, the inner wall of which is slidably connected to the outer wall of the second slide bar, and the bottom of the square frame is fixedly connected to the top of the valve stem of the gate valve. Beneficial effects

[0019] When a steel coil is placed on the support ramp, the gate valve control structure of this invention connects the modular heating component with the diversion pipe. Heating medium at 80-85°C directly enters the connected modular heating component through the inlet pipe, tee, and diversion pipe. The modular heating component heats the air, raising the air temperature near the steel coil to ≥50°C and increasing the surface temperature of the steel coil by 5-8°C. This reduces the temperature difference between the environment and the steel coil during sudden temperature changes, lessening the degree of condensation on the steel coil and preventing white rust. When no steel coil is placed on the support ramp, the gate valve control structure isolates and closes the modular heating component from the diversion pipe. This allows the modular heating component to heat areas with steel coils while remaining inactive in areas without them, facilitating automatic adjustment based on actual conditions without manual intervention, thus being more energy-efficient and environmentally friendly.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The present invention will be further described below with reference to the embodiments. Example 1

[0033] Please refer to the instruction manual appendix. Figure 1-8A finned heating device for reducing the risk of condensation on steel coils in a storage area includes multiple sets of equally spaced heating components 1;

[0034] Heating assembly 1 includes an inlet pipe 11, a tee 12, a diverter pipe 13, a return pipe 16, and a modular heating assembly. The input and output ends of the tee 12 are respectively connected to the inlet pipe 11 and the two diverter pipes 13. Multiple modular heating assemblies are symmetrically and equally spaced. The modular heating assemblies are fixedly installed on the opposite side walls of the two diverter pipes 13. The ends of the modular heating assemblies away from the diverter pipes 13 are connected to the return pipe 16. The inlet pipe 11 and the return pipe 16 are respectively fixedly connected to the output and input ends of the heating equipment.

[0035] A U-shaped support plate 2 is provided on the outer wall of the diversion pipe 13. Supporting inclined blocks 4 corresponding to the modular heating components are fixedly connected at equal intervals on the U-shaped support plate 2. The left and right adjacent supporting inclined blocks 4 are set opposite to each other.

[0036] The support ramp 4 is connected to a gate valve control structure 3 for communicating with the modular heating component at the corresponding position. The gate valve control structure 3 is connected to the control end of the modular heating component. When a steel coil is placed on the support ramp 4, the gate valve control structure 3 connects the modular heating component with the diversion pipe 13. When no steel coil is placed on the support ramp 4, the gate valve control structure 3 isolates and closes the modular heating component from the diversion pipe 13.

[0037] When a steel coil is placed on the support ramp 4, the gate valve control structure 3 connects the modular heating component with the diversion pipe 13. The heating medium at 80~85℃ directly enters the connected modular heating component through the inlet pipe 11, the tee 12, and the diversion pipe 13. The modular heating component heats the air, raising the air temperature near the steel coil to ≥50℃ and increasing the surface temperature of the steel coil by 5~8℃. This reduces the temperature difference between the environment and the steel coil when the temperature changes abruptly, reduces the degree of condensation on the steel coil, and prevents white rust from forming on the steel coil. When no steel coil is placed on the support ramp 4, the gate valve control structure 3 isolates and closes the modular heating component from the diversion pipe 13. This allows the modular heating component to heat areas with steel coils while not heating areas without steel coils. This facilitates automatic adjustment based on actual conditions without manual intervention, making it more energy-efficient and environmentally friendly.

[0038] The modular heating assembly includes a first horizontal tube 14, fins 15, a one-way valve 17, a straight tube 18, a gate valve 19, and a second horizontal tube 110. The gate valve 19 is fixedly installed at the end of the second horizontal tube 110 near the diversion pipe 13 and is fixedly connected to the gate valve control structure 3. The second horizontal tube 110 is fixedly connected to the diversion pipe 13. Straight tubes 18 are fixedly connected at equal intervals at the front and rear ends of the second horizontal tube 110. The end of the straight tube 18 away from the second horizontal tube 110 is fixedly connected to the first horizontal tube 14. A horizontal pipe 14 is fixedly connected to a return pipe 16. A one-way valve 17 is installed at the end of the return pipe 16 and is connected to the return pipe 16. Multiple sets of fins 15 are fixedly installed at equal intervals on a straight pipe 18. When a steel coil is placed on the support inclined block 4, the gate valve control structure 3 opens the gate valve 19 and the modular heating component is connected to the diversion pipe 13. When no steel coil is placed on the support inclined block 4, the gate valve control structure 3 closes the gate valve 19 and the modular heating component is isolated from the diversion pipe 13.

[0039] The gate valve 19 is located between the diversion pipe 13 and the straight pipe 18 near the diversion pipe 13;

[0040] The one-way valve 17 is located between the return pipe 16 and the straight pipe 18 near the return pipe 16;

[0041] When a steel coil is placed on the support block 4, the gate valve control structure 3 opens the gate valve 19 of the modular heating component, connecting the second horizontal pipe 110 and the diversion pipe 13. The heating medium at 80~85℃ directly enters the connected second horizontal pipe 110 of the modular heating component through the inlet pipe 11, the tee 12 and the diversion pipe 13, and then enters the straight pipe 18 to heat the straight pipe 18. The heated straight pipe 18 heats the fins 15. The straight pipe 18 and the fins 15 of the modular heating component heat the air, raising the air temperature near the steel coil to ≥50℃ and increasing the surface temperature of the steel coil by 5~8℃. This reduces the temperature difference between the environment and the steel coil when the temperature changes abruptly, reduces the degree of condensation on the steel coil, and achieves the purpose of preventing white rust from forming on the steel coil. The heated water enters the first horizontal pipe 14 through the straight pipe 18, and then flows back to the return pipe 16 through the first horizontal pipe 14 and the one-way valve 17, and then back to the heating equipment for secondary use.

[0042] The gate valve control structure 3 includes a follower component, a transmission component, and a connecting component. The support inclined block 4 has an L-shaped groove 32. The follower component is fixedly installed at the bottom of the vertical part of the L-shaped groove 32. The two ends of the transmission component are movably connected to the follower component and the connecting component, respectively. The transmission component is rotatably connected to the horizontal part of the L-shaped groove 32. The connecting component is fixedly connected to the valve stem of the gate valve 19. When no steel coil is placed on the support inclined block 4, the top of the follower component is higher than the top of the support inclined block 4, and the valve stem of the gate valve 19 is at the bottom. When a steel coil is placed on the support inclined block 4, the top of the follower component is lower than the top of the horizontal part of the L-shaped groove 32, and the valve stem of the gate valve 19 is at the top.

[0043] The follower assembly includes a convex plate 31, a sliding sleeve 34, an outer cylinder 35, and a spring 36. The lower end of the convex plate 31 is slidably connected to the inner wall of the vertical part of the L-shaped groove 32. The bottom of the convex plate 31 is fixedly connected to the top of the sliding sleeve 34 and the spring 36. The inner wall of the sliding sleeve 34 is slidably connected to the outer wall of the outer cylinder 35. The bottom of the outer cylinder 35 is fixedly connected to the bottom of the vertical part of the L-shaped groove 32. The spring 36 is located inside the outer cylinder 35. The convex plate 31 is connected to the transmission assembly. When no steel coil is placed on the support inclined block 4, the top of the convex plate 31 is higher than the top of the support inclined block 4, and the valve stem of the gate valve 19 is at the lowest end. When a steel coil is placed on the support inclined block 4, the top of the convex plate 31 is lower than the top of the horizontal part of the L-shaped groove 32, and the valve stem of the gate valve 19 is at the highest end.

[0044] The transmission assembly includes a first slide rod 33, a connecting shaft 38, a second slide rod 310, and a rotating rod 311. A transverse groove 37 is provided at the lower end of the convex plate 31. The first slide rod 33 is slidably connected to the inner wall of the transverse groove 37.

The middle end of the rotating rod 311 is rotatably connected to the connecting shaft 38, and the connecting shaft 38 is rotatably connected to the transverse part of the L-shaped groove 32. The second slide rod 310 is movably connected to the connecting assembly.

[0045] The connecting component includes a square frame 39, the inner wall of which is slidably connected to the outer wall of the second slide bar 310, and the bottom of the square frame 39 is fixedly connected to the top of the valve stem of the gate valve 19.

[0046] When a steel coil is placed on the support inclined block 4, the steel coil contacts the convex plate 31 of the follower component of the gate valve control structure 3, pushing the convex plate 31 to move downward. The convex plate 31 drives the transverse groove 37 to move downward, and the transverse groove 37 drives the first slide rod 33 to move downward. Under the rotational guidance of the connecting shaft 38, the first slide rod 33 drives the rotating rod 311 to rotate along the connecting shaft 38. The end of the rotating rod 311 that contacts the second slide rod 310 rotates upward. The rotating rod 311 drives the second slide rod 310 to rotate upward. The second slide rod 310 drives the square frame 39 to move upward. The square frame 39 drives the valve stem of the gate valve 19 to move upward. The square frame 39 opens the gate valve 19 of the modular heating component, and the second transverse pipe 110 is connected to the diversion pipe 13, so that the modular heating component can heat.

[0047] When no steel coil is placed on the support inclined block 4, the spring 36 of the follower component of the gate valve control structure 3 drives the convex plate 31 to move upward, the sliding sleeve 34 and the outer cylinder 35 provide guidance, the convex plate 31 drives the transverse groove 37 to move upward, the transverse groove 37 drives the first sliding rod 33 to move upward, under the rotational guidance of the connecting shaft 38, the first sliding rod 33 drives the rotating rod 311 to rotate along the connecting shaft 38, the end of the rotating rod 311 that contacts the second sliding rod 310 rotates downward, the rotating rod 311 drives the second sliding rod 310 to rotate downward, the second sliding rod 310 drives the square frame 39 to move downward, the square frame 39 drives the valve stem of the gate valve 19 to move downward, the square frame 39 closes the gate valve 19 of the modular heating assembly, the second horizontal pipe 110 is isolated from the diversion pipe 13, and the modular heating assembly does not perform heating.

[0048] The modular heating components are used to heat areas with steel coils, while they are not used to heat areas without steel coils. This allows for automatic adjustment based on actual conditions without manual intervention, making it more energy-efficient and environmentally friendly.
