Description

Technical Field

[0001] This utility model relates to the field of cooling devices, and in particular to a cooling device for hot-dip galvanized steel sheets. Background Technology Hot-dip galvanizing, also known as hot-dip zinc plating, is an effective method of metal corrosion protection. It is mainly used in metal structures in various industries. Cooling devices for hot-dip galvanized steel sheets are equipment used to cool down the steel sheets after hot-dip galvanizing to prevent operators from being burned.

[0002] A search revealed Chinese patent publication number CN213295467U, which discloses a cooling device for hot-dip galvanizing processes. The device includes a hot-melt tank and a support frame. The hot-melt tank is located beside the support frame. A steering shaft is rotatably connected to the hot-melt tank via bearings. Steel plates are attached to the outer wall of the steering shaft. One end of the support frame is bolted to an air-cooling box. Symmetrically arranged fans are bolted to the inner wall of the air-cooling box. A reversing shaft is rotatably connected to the air-cooling box via bearings above it. Symmetrically arranged extrusion shafts are rotatably connected to the air-cooling box via bearings below it. A cleaning box is bolted to the top of the support frame. This invention has a simple structure and is easy to use. It can quickly hot-dip galvanize steel plates. The combination of air and water cooling can rapidly cool liquid zinc while simultaneously cleaning some impurities. The extrusion shafts and guide plates allow excess liquid zinc to return to the hot-melt tank, saving zinc and reducing costs.

[0003] The aforementioned patent specification mentions that "in use, the steel plate is sequentially passed through the steering shaft 3, extrusion shaft 4, and air-cooling box 5, then reversed by the reversing shaft 7, and finally passed through the cleaning box 8 before being fixed on the recovery shaft 11. During operation, the hot melt box 1 is first heated to melt the zinc inside and then adhere it to the steel plate 2. At the same time, the motor 13 works, driving the recovery shaft 11 to rotate, which in turn drives the steel plate 2 to move. This allows the soaked steel plate 2 to pass through the extrusion shaft 4, squeezing out excess liquid zinc, which then drips back into the hot melt box 1. Then, the fan starts working, drawing in cold air to cool and solidify the zinc on the surface. The hot air can be discharged through the channel. Then, the solidified zinc on the surface changes direction through the reversing shaft 7 and enters the cleaning box 8. At this time, the spray plate 9 starts working to clean and cool the steel plate." This process ensures the zinc is completely cured and removes impurities from the galvanized surface. Finally, the steel plate 2 is wound onto the recycling shaft 11 for storage and transportation. This invention has a simple structure and is easy to use, allowing for quick hot-dip galvanizing of steel plates. The combination of air and water cooling rapidly cools the liquid zinc while cleaning some impurities. The extrusion shaft and guide plate allow excess liquid zinc to return to the hot-melt box 1, saving zinc usage and costs. While the above allows for the combined use of air and water cooling, it cannot achieve a combined cyclic and two-step cooling process, thus hindering stepped cooling, reducing stability and product quality during processing. Therefore, a cooling device for hot-dip galvanized steel plates is proposed to solve these problems. Utility Model Content

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.

[0031] Example: A cooling device for hot-dip galvanized steel sheets, referenced Figure 1 , Figure 3 and Figure 4 The system includes a support frame 1, which provides a stable working platform for subsequent cooling, cleaning and other processes, ensuring the safety and reliability of the processing. A processing frame 2 is fixedly connected to the top of the support frame 1. The processing frame 2 surrounds the cooling area, so that the airflow generated by the cooling fan 31 and the heat exchange of the cooling pipe 33 are concentrated inside, improving the cooling efficiency. At the same time, the heat dissipation holes 34 on its inner side can guide the internal heat out. A dual-function cooling mechanism 3 is set inside the processing frame 2. The dual-function cooling mechanism 3 includes two cooling fans 31. The cooling fans 31 accelerate the airflow inside the processing frame 2, promote heat exchange, and assist in the cooling of the cooling pipe 33 and the hot-dip galvanized steel plate. The two cooling fans 31 are fixedly connected to the top side of the processing frame 2. Specifically, after the hot-dip galvanized steel sheet enters the processing frame 2 at the top of the support frame 1, the dual-function cooling mechanism 3 starts operating, and two cooling fans 31 are activated to accelerate the airflow inside the processing frame 2, causing the air to circulate rapidly within the processing frame 2. Simultaneously, the cooling pipes 33 participate in the heat exchange process, transferring heat with the hot-dip galvanized steel sheet to lower its temperature. Under the airflow driven by the cooling fans 31, the heat generated by the exchange between the hot-dip galvanized steel sheet and the cooling pipes 33 is carried by the airflow and then discharged to the outside of the processing frame 2 through the heat dissipation holes 34 on the inner side of the processing frame 2, completing the cooling process of the hot-dip galvanized steel sheet.

[0032] The dual-function cooling mechanism 3 has two fixedly connected guide plates 32 inside. The guide plates 32 absorb the heat inside the processing frame 2 and transfer the heat to the cooling pipes 33 in contact with them. At the same time, they guide the airflow and heat flow direction. The top of the support frame 1 has two fixedly connected cooling pipes 33. The cooling pipes 33 serve as flow channels for coolant. The circulating flow of coolant in the pipes absorbs the heat transferred by the guide plates 32, thereby indirectly cooling the inside of the processing frame 2 and the hot-dip galvanized steel plate. A connecting pipe 3603 is fixedly connected to the adjacent side of the two cooling pipes 33. The connecting pipe 3603 connects the two cooling pipes 33, allowing coolant to flow from the first cooling pipe 33 into the second cooling pipe 33, forming a complete flow path. The top of the support frame 1 has a fixedly connected support water tank 35. The support water tank 35 stores coolant and provides water source for the circulation component 36 and the spray component 37. At the same time, it receives the circulating coolant, thereby realizing centralized management and recycling of coolant. Specifically, the heat generated inside the processing frame 2 is absorbed by the guide plate 32, which guides the airflow and heat to the cooling pipe 33. Inside the cooling pipe 33 at the top of the support frame 1, the coolant absorbs the heat transferred by the guide plate 32 through circulation, achieving indirect cooling of the inside of the processing frame 2 and the hot-dip galvanized steel plate. The coolant flows from the first cooling pipe 33 into the second cooling pipe 33 through the connecting pipe 3603, forming a complete flow path. The support water tank 35 stores the coolant and provides a water source for the circulation component 36 and the water spray component 37. The circulation component 36 drives the coolant circulation, and the water spray component 37 sprays water to cool specific areas. The support water tank 35 receives the circulating coolant, realizing centralized management and recycling of the coolant.

[0033] A circulation assembly 36 is fixedly connected inside the supporting water tank 35. The circulation assembly 36 includes a pump a3601, which provides power for the circulation of coolant, drawing coolant from the supporting water tank 35 and delivering it to the cooling pipe 33. The inlet end of the pump a3601 is fixedly connected to the bottom inner side of the supporting water tank 35, and the outlet end of the pump a3601 is fixedly connected to an outlet pipe a3602. The outlet pipe a3602 connects the pump a3601 and the cooling pipe 33, serving as the coolant flow path from the water tank to the cooling pipe 33. The output end of the output pipe a3602 is fixedly connected to the inside of one of the cooling pipes 33. The bottom side of the other cooling pipe 33 is fixedly connected to a circulation output pipe 3605. The circulation output pipe 3605 guides the coolant that has absorbed heat in the second cooling pipe 33 back to the support water tank 35, completing the circulation loop of the coolant. A control valve 3604 is fixedly connected to the outside of the circulation output pipe 3605. The control valve 3604 controls the flow rate and on / off state of the coolant in the circulation output pipe 3605. Specifically, a circulation assembly 36 is fixedly connected inside the supporting water tank 35. The circulation assembly 36 includes a pump a3601, which provides power for the circulation of coolant, drawing coolant from the supporting water tank 35 and delivering it to the cooling pipe 33. The inlet end of the pump a3601 is fixedly connected to the bottom inner side of the supporting water tank 35, and the outlet end of the pump a3601 is fixedly connected to an outlet pipe a3602. The outlet pipe a3602 connects the pump a3601 and the cooling pipe 33. The coolant is transported from the water tank to the cooling pipe 33. The output end of the output pipe a3602 is fixedly connected to the inside of one of the cooling pipes 33. After the coolant absorbs heat in the cooling pipe 33, it is guided back to the supporting water tank 35 through the circulation output pipe 3605 fixedly connected to the bottom side of the other cooling pipe 33, thus completing the circulation loop of the coolant. A control valve 3604 is fixedly connected to the outside of the circulation output pipe 3605. The control valve 3604 controls the flow rate and on / off state of the coolant in the circulation output pipe 3605.

[0034] Reference Figure 1 and Figure 2A water spray assembly 37 is fixedly connected inside the supporting water tank 35. The water spray assembly 37 includes a pump b3701, which guides the high-pressure coolant output by the pump b3701 to one of the connecting pipes 3704, providing a channel for subsequent diversion and spraying. The pump b3701 provides power for water spray cooling, drawing coolant from the supporting water tank 35 and delivering it to the spraying system. The inlet end of the pump b3701 is fixedly connected to the inner bottom of the supporting water tank 35, and the outlet end of the pump b3701 is fixed... An output pipe b3702 is connected, and one of the connecting pipes 3704 is fixedly connected to the output end of the output pipe b3702. The connecting pipe 3704 serves as a coolant distribution pipe, distributing the coolant delivered by the output pipe b3702 to multiple spray heads 3706. Simultaneously, two connecting pipes 3704 are connected via vertical pipes 3705 to form a complete spray pipeline. Two vertical pipes 3705 are fixedly connected inside one of the connecting pipes 3704, and the vertical pipes 3705 ensure the coolant pressure within the two connecting pipes 3704. To ensure uniform flow and avoid differences in water output from spray heads 3706 due to uneven pressure, thus guaranteeing consistent secondary cooling, another vertical pipe 3705 is fixedly connected to the top of two connecting pipes 3704. Multiple spray heads 3706 are fixedly connected inside the two connecting pipes 3704. Under pressure, coolant is sprayed from the small orifices of the spray heads 3706, forming a uniformly distributed water flow that directly contacts the hot-dip galvanized steel sheet. Through heat exchange, it absorbs heat from the surface of the steel sheet, completing the secondary cooling process. An L-shaped support plate 3703 is fixedly connected to the middle of the support frame 1. The L-shaped support plate 3703 fixes the position of the two connecting pipes 3704 to ensure the stability of the spraying system during operation. The two connecting pipes 3704 are fixedly connected to the inside of the L-shaped support plate 3703. Multiple heat dissipation holes 34 are opened on both sides of the inside of the processing frame 2. The heat dissipation holes 34 serve as channels for the heat to be discharged from the inside of the processing frame 2, and help to release excess heat that is not absorbed by the coolant during the cooling process. A cleaning mechanism 4 is provided on the top of the support frame 1. Specifically, when the device is running, the coolant in the support water tank 35 is drawn from the bottom inside by the pump b3701 and delivered to one of the connecting pipes 3704 through the output pipe b3702. The coolant flows in the connecting pipe 3704 and enters the other connecting pipe 3704 through two vertical pipes 3705, so that the coolant is distributed in the two connecting pipes 3704. Subsequently, the coolant is sprayed out from multiple spray heads 3706 under pressure and comes into contact with the hot-dip galvanized steel plate. At the same time, the excess heat inside the processing frame 2 is discharged through multiple heat dissipation holes 34, while the cleaning mechanism 4 on the top of the support frame 1 is in a standby state.

[0035] Reference Figures 5 to 7The cleaning mechanism 4 includes two connecting plates 41. The bottom of the connecting plates 41 is fixed to the top of the support frame 1, and a cylinder 4201 is installed inside. The top is connected to a sliding support plate 46 to ensure stability during the cleaning process. The bottom of the two connecting plates 41 is fixedly connected to the top of the support frame 1. A drive assembly 42 is fixedly connected inside the connecting plates 41. The drive assembly 42 includes two cylinders 4201. The cylinders 4201 realize flexible adjustment of the cleaning height to ensure that the cleaning sponge cloth 44 is in close contact with the surface of hot-dip galvanized steel plates of different specifications. The outside of the two cylinders 4201 is fixedly connected to the inside of the connecting plates 41. The drive end of the cylinders 4201 is fixedly connected to the sliding support plate 46. The bottom of the sliding support plate 46 is fixedly connected to a support protective shell 4202. The support protective shell 4202 extends the service life of the motor 4203, ensures its operational stability, reduces failures caused by external factors, and reduces maintenance costs. Specifically, the cylinders 4201 inside the two connecting plates 41 at the top of the support frame 1 are activated, driving the sliding support plate 46 connected at the top to adjust its height, so that the cleaning sponge cloth 44 at the bottom is in close contact with the surface of the hot-dip galvanized steel plate, realizing flexible adjustment of the cleaning height to adapt to steel plates of different specifications. A motor 4203 is installed in the support protective shell 4202 at the bottom of the sliding support plate 46. The motor 4203 drives the cleaning sponge cloth 44 to rotate and clean the surface of the steel plate. During the cleaning process, the cylinders 4201 continuously provide stable support to improve the cleaning effect.

[0036] A motor 4203 is fixedly connected inside the protective shell 4202. The motor 4203 provides power for the rotation of the cleaning sponge 44, driving it to rotate to wipe the surface of the hot-dip galvanized steel plate. A rotating column 43 is fixedly connected to the drive end of the motor 4203. The rotating column 43 connects the motor 4203 and the cleaning sponge 44, transmitting the rotational power of the motor 4203 to the cleaning sponge 44 and fixing the position of the cleaning sponge 44. The cleaning sponge 44 is detachably connected to the outside of the rotating column 43. The cleaning sponge 44 efficiently removes moisture from the surface of the steel plate, avoiding oxidation and rust caused by moisture residue, while removing impurities, ensuring the smoothness of the steel plate surface, and improving product quality. A sliding support plate 46 is fixedly connected to the top of the two connecting plates 41, and the cleaning sponge 44 is rotatably connected to the bottom of the sliding support plate 46. Specifically, after the motor 4203 inside the protective shell 4202 is started, it drives the rotating column 43 to rotate, which in turn drives the cleaning sponge cloth 44 to rotate. At this time, the sliding support plate 46, supported by the two connecting plates 41, drives the cleaning sponge cloth 44 at the bottom to move to the surface of the hot-dip galvanized steel plate. The rotating cleaning sponge cloth 44 makes full contact with the surface of the steel plate, realizing the rapid removal of moisture and impurities from the surface of the steel plate. During the cleaning process, the cleaning sponge cloth 44 can be disassembled and replaced through the rotating column 43 to ensure the cleaning effect. The device is powered by the motor 4203, and with the coordinated operation of the rotating column 43, the cleaning sponge cloth 44 and the sliding support plate 46, the smoothness of the steel plate surface is ensured.

[0037] The quick-connect component 45 includes a hook surface 4501, which enables quick installation and removal of the cleaning sponge cloth 44 without tools, saving replacement time and improving maintenance efficiency. The top of the hook surface 4501 is fixedly connected to the left side of the cleaning sponge cloth 44, and a textured surface 4502 is fixedly connected to the left side of the cleaning sponge cloth 44. The textured surface 4502 and the hook surface 4501 form a reliable detachable connection, ensuring that the cleaning sponge cloth 44 will not fall off during rotation, while also facilitating disassembly and reducing maintenance difficulty. The bottom of the hook surface 4501 is connected to the textured surface 4501. The top of 2 is bonded to each other. The left side of the cleaning sponge 44 is fixedly connected to the quick connection component 45. The outside of the cleaning sponge 44 is rotatably connected to the bottom of the sliding support plate 46. The sliding support plate 46 ensures the overall synchronous movement of the cleaning components, ensures the relative position stability of each component, and makes the height adjustment of the cleaning sponge 44 accurate and reliable. The top side of the support frame 1 is fixedly connected to the conveyor belt 5, which conveys the hot-dip galvanized steel plate and makes it pass through the cooling area of ​​the dual-function cooling mechanism 3 and the cleaning area of ​​the cleaning mechanism 4 in sequence to achieve continuous processing. Specifically, after the motor 4203 starts, the power is transmitted to the rotating column 43, causing the rotating column 43 to start rotating. The cleaning sponge cloth 44 installed on the rotating column 43 rotates synchronously. At the same time, the sliding support plate 46 moves under the support of the two connecting plates 41, bringing the cleaning sponge cloth 44 at its bottom closer to and finally reaching the surface of the hot-dip galvanized steel plate. The rotating cleaning sponge cloth 44 makes full contact with the surface of the steel plate, and removes moisture and impurities from the surface of the steel plate during the continuous rotation. When the cleaning sponge cloth 44 needs to be replaced, it can be directly removed from the rotating column 43, and the cleaning operation can continue after replacing it with a new cleaning sponge cloth 44.

[0038] The implementation principle of this application embodiment is as follows: First, before entering, the pump a3601 is started to draw water from the water tank 35, which then enters one of the cooling pipes 33. The water then enters the other cooling pipe 33 through the connecting pipe 3603, thus providing coolant. Simultaneously, the conveyor belt 5 is started to deliver the hot-dip galvanized steel plate, and the cooling fan 31 is started to exchange internal temperatures. The guide plate 32 inside the processing frame 2 absorbs heat and transfers it to the cooling pipes 33. Heat can also be output from the heat dissipation holes 34, and the circulating output pipe 36... At the bottom of another circulation output pipe 3605, the coolant is circulated and reused through the control valve 3604. Simultaneously, the pump b3701 is started to draw water from the support water tank 35 into the connecting pipe 3704 and spray it evenly through the spray head 3706, thus cooling the hot-dip galvanized sheet a second time. This achieves circulation and double cooling, which not only realizes the stepped cooling of the hot-dip galvanized steel sheet, ensuring the stability of the processing and product quality, but also achieves energy saving and environmental protection, and reduces costs.

[0039] Secondly, after cooling, it can enter the bottom of the cleaning mechanism 4, and the height can be adjusted by the cylinder 4201. The motor 4203 is started to drive the rotating column 43 and the cleaning sponge cloth 44 to rotate, cleaning the surface of the hot-dip galvanized sheet. At the same time, the use of the hook side 4501 and the rough side 4502 allows the cleaning sponge cloth 44 to be quickly replaced, thereby quickly absorbing water from the surface of the hot-dip galvanized sheet, saving replacement time and improving maintenance efficiency.
