Description

Technical Field

[0001] The utility model belongs to the technical field of cooling tanks, and particularly relates to an efficient cooling tank for steel strip welded steel pipes. Background Art

[0002] In the traditional cooling process of steel strip welded steel pipes, it generally relies on static coolant pools or basic spray systems. Although these methods are widely used, they inevitably expose drawbacks such as low cooling efficiency, uneven cooling effect, and significant energy consumption. For example, the efficient cooling tank described in the Chinese utility model patent with the publication number CN220372497U. Static coolant is difficult to ensure uniform and rapid cooling of all parts of the steel pipe surface, while a simple spray system may result in an unsatisfactory cooling effect due to uneven water flow distribution. At the same time, these cooling methods may also cause uneven thermal stress on the steel pipe surface, affecting the mechanical properties and dimensional accuracy of the steel pipe. In addition, during the cooling process of the spray method, water or other coolant media are usually sprayed onto the object to be cooled in the form of mist or small droplets through nozzles. This spraying method is prone to generating a large amount of water mist. The generation of water mist not only increases the humidity in the air but may also have a certain impact on the surrounding environment, such as blurred vision and equipment corrosion.

[0003] Therefore, it is very necessary to invent an efficient cooling tank for steel strip welded steel pipes. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides an efficient cooling tank for steel strip welded steel pipes, which includes a cooling tank chassis, a cooling water tank, and a steam connecting pipe. The cooling tank chassis and the cooling water tank are fixedly installed and connected to each other, and both are connected to the steam connecting pipe. The cooling tank chassis is located above the cooling water tank;

[0005] The cooling tank chassis includes a flowing cooling box, a discharge pipe orifice, an inlet and outlet slot, a lifting roller frame, a cylinder, a steam collecting hood, and a fan. The flowing cooling box is fixed to the circulating box body of the cooling water tank. The flowing cooling box is provided with the discharge pipe orifice, and the inlet and outlet slot is opened above the end face. The lifting roller frame is located inside the inlet and outlet slot, and the lifting roller frame is fixed to the output end of the cylinder fixedly installed outside the flowing cooling box; the steam collecting hood and the fan are respectively fixedly installed outside the flowing cooling box, and the steam collecting hood, the steam connecting pipe, and the circulating box body are connected to each other;

[0006] The cooling water tank includes a return cooling plate, a cooling pipe group, a flow water pump, and an injection pipeline. A plurality of the return cooling plates are fixedly installed inside the circulation box body. The cooling pipe group sequentially passes through the return cooling plates, and the inlet and outlet ports of the cooling pipe group are installed on both outer sides of the circulation box body. The circulation box body is communicated with the flowing cooling box through the flow water pump and the injection pipeline.

[0007] Preferably, the lifting roller frame is composed of a C-shaped outer frame and lifting rollers. The C-shaped outer frame is fixed to the output end of the cylinder. A plurality of the discharge pipe orifices are located below one of the lifting roller frames. The discharge pipe orifice penetrates into the circulation box body and is located on one side of the return cooling plate.

[0008] For an efficient cooling tank for steel strip welded steel pipes as described in the claims, it is characterized in that: a plurality of the return cooling plates are arranged in a staggered manner inside the circulation box body. The cooling pipe group inside the return cooling plate has a serpentine path and exits the return cooling plate in a horizontal direction.

[0009] Preferably, the circulation box body is communicated with the input port of the flow water pump at one end outside itself. The output port of the flow water pump is communicated with the inside of the flowing cooling box through the injection pipeline. The end of the injection pipeline that penetrates into the flowing cooling box is located below one of the lifting roller frames.

[0010] Preferably, a steam through hole is opened above the flowing cooling box. The fan is located outside the steam through hole provided in the flowing cooling box. The fan is located inside the steam collection cover. The steam collection cover is a conical geometric body structure. The steam retained inside the steam collection cover is guided into the circulation box body through the steam communication pipe.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] The present utility model innovatively adopts a dynamic cooling mechanism. Specifically, the cooling tank chassis does not directly store the coolant. Instead, a flow water pump extracts the coolant from the cooling water tank and sprays it vigorously into the tank to form a dynamic cycle, enabling the coolant to come into contact with the surface of the steel pipe more comprehensively, greatly improving the heat exchange efficiency, and thus rapidly reducing the temperature of the steel pipe. During this process, the coolant continuously circulates between the cooling tank and the cooling water tank. After being intensively cooled by the return cooling plate and the serpentine path cooling pipe group, it always remains in a low-temperature state, further enhancing the cooling effect. In addition, the lifting roller frame in the flow cooling box ensures that the steel pipe is evenly cooled during movement, avoiding cooling blind spots and achieving comprehensive and uniform cooling. Notably, the ingenious combination of the steam collection hood and the fan effectively recovers and re-uses the steam heat generated during the cooling process, reducing environmental pollution and improving energy utilization efficiency. The overall design embodies the advanced concepts of high efficiency, environmental protection, and energy conservation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] As shown in the attached Figure 1 to the attached Figure 3 drawings:

[0021] A high-efficiency cooling tank for a steel strip welded steel pipe provided by the present invention includes a cooling tank chassis 1, a cooling water tank 2, and a steam connecting pipe 3. The cooling tank chassis 1 and the cooling water tank 2 are fixedly installed and connected to each other, and both are connected to the steam connecting pipe 3. The cooling tank chassis 1 is located above the cooling water tank 2.

[0022] Furthermore, the cooling tank chassis 1 includes a flowing cooling tank 11, a discharge pipe orifice 12, an inlet and outlet slot 13, a lifting roller frame 14, a cylinder 15, a steam collecting hood 16, and a blower 17. The flowing cooling tank 11 is fixed to the circulating tank body 21 of the cooling water tank 2. The flowing cooling tank 11 is provided with the discharge pipe orifice 12, and the inlet and outlet slot 13 is opened above the end face. The lifting roller frame 14 is located inside the inlet and outlet slot 13, and the lifting roller frame 14 is fixed to the output end of the cylinder 15 fixedly installed outside the flowing cooling tank 11. The steam collecting hood 16 and the blower 17 are respectively fixedly installed outside the flowing cooling tank 11, and the steam collecting hood 16, the steam connecting pipe 3, and the circulating tank body 21 are connected to each other.

[0023] Furthermore, the cooling water tank 2 includes a return cooling plate 22, a cooling pipe group 23, a flow water pump 24, and an injection pipe 25. A plurality of the return cooling plates 22 are fixedly installed inside the circulation box body 21. The cooling pipe group 23 sequentially passes through the return cooling plates 22, and the inlet and outlet ports of the cooling pipe group 23 are installed on both outer sides of the circulation box body 21. The circulation box body 21 is communicated with the flow cooling box 11 through the flow water pump 24 and the injection pipe 25.

[0024] Furthermore, the lifting roller frame 14 is composed of a C-shaped outer frame and lifting rollers. The C-shaped outer frame is firmly fixed on the output end of the air cylinder 15 to ensure that the lifting roller frame 14 can adjust its height and position as needed. A waterproof and high-temperature resistant motor is fixedly installed on the outside of the C-shaped outer frame. The output end of the motor is fixed to the lifting roller, which is used to drive the lifting roller to convey steel pipes. Particularly, a plurality of discharge nozzles 12 are cleverly arranged below one of the lifting roller frames 14. These discharge nozzles 12 not only penetrate the wall surface of the circulation box body 21 but are also cleverly placed on one side of the return cooling plate 22. Such a layout helps the coolant to be smoothly discharged after completing the cooling task and directly enter the circulation box body 21 for re-cooling.

[0025] Furthermore, inside the circulation box body 21, the return cooling plates 22 are carefully arranged in an alternating pattern, which maximizes the flow path and contact area of the coolant. Each return cooling plate 22 is inlaid with a cooling pipe group 23 with a serpentine path. These cooling pipe groups 23 pass through in a complex serpentine path and finally exit horizontally on one side of the return cooling plate 23. Such a design not only improves the cooling efficiency of the coolant but also ensures that the coolant can fully release heat during the circulation process, preparing for subsequent cooling work.

[0026] Furthermore, the circulation box body 21 is closely connected to the external water pump 24 system to form a complete coolant circulation loop. One port of the circulation box body 21 is communicated with the input port of the flow water pump 24, which is responsible for extracting the preliminarily cooled coolant. The output port of the flow water pump 24 is communicated with the inside of the flow cooling box 11 through the injection pipe 25. The other end of the injection pipe 25 cleverly passes through the wall surface of the flow cooling box 11 and is located below one of the lifting roller frames 14. Such a layout ensures that the coolant can be accurately sprayed onto the surface of the steel pipe to achieve efficient cooling.

[0027] Furthermore, in order to further improve the cooling efficiency and environmental performance, the cooling tank is also equipped with a steam collection and reuse system. A steam through-hole is opened above the flowing cooling box 11 for discharging the steam generated during the cooling process. The fan 17 is installed outside the steam through-hole and inside the steam collection hood 16. The steam collection hood 16 adopts a conical geometric structure, which can effectively gather the steam and guide it into the steam connecting pipe 3. Finally, the steam connecting pipe 3 guides the collected steam back into the circulation box body 21 for reuse, which not only reduces environmental pollution but also improves the energy utilization efficiency.

[0028] The working principle is as follows: First, when the steel strip welded steel pipe enters the flowing cooling box 11 through the inlet and outlet notch 13, the lifting roller frame 14 will support and guide the steel pipe to move in the cooling tank. The height and position of the lifting roller frame 14 can be adjusted by the cylinder 15 to adapt to steel pipes of different diameters or lengths.

[0029] Then, the flowing water pump 24 starts to work, extracting the preliminarily cooled coolant from the circulation box body 21 of the cooling water tank 2. These coolants are pumped into the flowing cooling box 11 through the injection pipe 25 and submerge the steel pipe. Under strong pressure, the coolant is sprayed out vigorously into the flowing cooling box 11, forming a dynamic cycle and fully contacting the surface of the steel pipe.

[0030] Inside the flowing cooling box 11, the coolant exchanges heat with the surface of the steel pipe, quickly taking away the heat on the steel pipe. As the steel pipe moves, all parts of its surface can be evenly contacted with the flowing coolant medium, avoiding cooling blind spots and achieving comprehensive and uniform cooling.

[0031] After completing the cooling task, the coolant flows back into the circulation box body 21 through the discharge pipe orifice 12. Inside the circulation box body 21, the coolant is further cooled by the folding cooling plate 22 and the cooling tube group 23 with a serpentine path. The staggered arrangement of the folding cooling plates 22 and the serpentine path design of the cooling tube group increase the flow path and contact area of the coolant, improving the cooling efficiency. When the coolant flows through the folding cooling plate, it fully releases heat, reduces the temperature, and then re-enters the cooling tank to form a continuous cycle.

[0032] At the same time, the steam generated during the cooling process is discharged through the steam through-hole above the flowing cooling box 11. The steam collection hood 16 adopts a conical geometric structure, effectively gathering the steam and guiding it into the steam connecting pipe 3. The fan 17 is installed inside the steam collection hood 16, and through the negative pressure generated by it, the steam is sucked in and guided back into the circulation box body 21. In this way, the heat in the steam can be recycled and used in the cooling process, improving the energy utilization efficiency and reducing the environmental pollution caused by the steam.

[0033] Any technical solution using the technical solution of the present utility model, or a similar technical solution designed by those skilled in the art inspired by the technical solution of the present utility model and achieving the above technical effects, shall fall within the protection scope of the present utility model.
