Description

Technical Field

[0001] This utility model relates to the technical field of furnace cooling equipment, specifically to copper cooling plates. Background Technology

[0002] Generally, a blast furnace for ironmaking is divided into five parts from top to bottom: the throat, the body, the waist, the belly, and the hearth. The belly, waist, and lower part of the body are located in the high-temperature and molten zone, requiring cooling equipment and refractory materials to inhibit corrosion and extend the furnace's service life. Copper cooling plates, widely used in blast furnaces, are typically installed in a dense distribution among the refractory materials within the furnace walls to enhance cooling. Because the copper cooling plates are horizontally inserted into the blast furnace, their front ends are inserted relatively deep into the furnace at higher temperatures, making them prone to damage and resulting in a shorter lifespan.

[0003] Currently, copper cooling plates are made of high thermal conductivity pure copper or copper alloys, manufactured through casting or rolling (forging or rolling) copper plates with drilling and welding processes. They mainly include cavity-type cast copper cooling plates, embedded-tube cast copper cooling plates, and rolled copper wall-drilled and welded copper cooling plates. However, because cast copper has lower thermal conductivity than rolled copper, and the casting process inevitably introduces defects such as porosity, air bubbles, and cracks, cavity-type cast copper cooling plates suffer from slow water flow in the cavity chamber, and the tendency for vortex zones to form at the baffle ends, resulting in poor cooling performance. Embedded-tube cast copper cooling plates also have poor thermal conductivity, and there is an air gap thermal resistance between the embedded copper tubes and the main body. The body of the rolled copper wall drilled and welded copper cooling plate is made of rolled copper plate, which is then drilled and welded. Although the thermal conductivity of rolled copper plate is worse than that of cast copper, the front end of the rolled copper wall drilled and welded copper cooling plate is usually provided with a through hole in order to facilitate the drilling. The through hole needs to be sealed by welding plugs, which makes it difficult to make the water channel layout uniform and dense, resulting in a mediocre cooling effect and easy damage. Utility Model Content

[0004] In view of this, the present invention provides a copper cooling plate to solve the problem that the front end of the copper cooling plate is difficult to evenly and densely arranged for water channels due to the setting of the welded plug, resulting in mediocre cooling effect and easy damage.

[0005] This utility model provides a copper cooling plate, comprising:

[0006] The cooling plate body includes a main water chamber and at least two branch water chambers. The main water chamber is located at the rear end of the cooling plate body, and the rear end of the cooling plate body has an opening communicating with the main water chamber. One end of each branch water chamber communicates with the main water chamber, and the other end extends toward the front end of the cooling plate body.

[0007] The pipeline structure includes a main pipe and at least two branch pipes connected to the main pipe. The main pipe is spaced apart in the main water chamber and forms a first flow channel with the main water chamber. The branch pipes are spaced apart in the branch water chambers and form a second flow channel with the branch water chambers. The first flow channel and the second flow channel are connected. The main pipe is provided with an inlet, and the end of the branch pipe away from the main pipe is provided with an outlet connected to the second flow channel.

[0008] A cover plate is sealed to the opening. The cover plate is provided with an outlet and a connection port that communicate with the main water chamber. The connection port is connected to the inlet.

[0009] Beneficial effects: The rear end of the cooling plate body is open, which facilitates the opening of the main water chamber from the rear end to the front end on the cooling plate body through the opening. It also facilitates the even and dense opening of branch water chambers through the opening and the main water chamber, resulting in good cooling effect and less damage. At the same time, it is also convenient to connect the pipeline structure inside the cooling plate body through the opening. The main pipe and the main water chamber form the first flow channel, and the branch pipe and the branch water chamber form the second flow channel. The end of the branch pipe away from the main pipe has an outlet that communicates with the second flow channel. There is no need to open the front end of the cooling plate body. The heat exchange circulation channel can be formed through the inlet, main pipe, branch pipe, second flow channel, first flow channel and outlet. This avoids the uneven water channel layout caused by welding plugs to seal the front end of the copper cooling plate. Each main water chamber can be connected to at least two branch water chambers, and each main pipe can be connected to at least two branch pipes. Multiple branch water chambers and branch pipes can be evenly arranged to form multiple secondary flow channels, achieving better cooling effects. The cooling effect is relatively uniform among the branch pipes and the secondary flow channels. The cap seals the opening, sealing the main water chamber and branch water chambers to prevent coolant overflow.

[0010] When the copper cooling plate is working, the coolant enters the main pipe through the inlet on the main pipe, and then flows through the main pipe to various branch pipes. In the branch pipes, it flows from back to front through the outlet to the front end of the cooling plate body. Then, it flows back from front to back through the second flow channel between the branch pipe and the branch water chamber, and reaches the first flow channel between the main pipe and the main water chamber. Finally, it flows out through the outlet, forming a heat exchange cycle and carrying away heat. This increases the flow direction of the coolant in the copper cooling plate, extends the flow distance of the coolant in the copper cooling plate, and improves the overall heat exchange effect.

[0011] In one alternative embodiment, the outlet is disposed on the end face of the branch pipe facing away from the main pipe, and the outlet is spaced apart from the end face of the branch water chamber that is away from the main water chamber.

[0012] Beneficial effects: After entering the main pipe through the inlet, the coolant enters the branch pipe and directly impacts the end face of the branch pipe facing away from the main pipe through the outlet. Since the end face of the branch pipe facing away from the main pipe is close to the front end of the cooling plate body, the coolant can directly impact the front end of the cooling plate body and flow back into the second flow channel at the front end, thereby enhancing the heat exchange effect at the front end of the copper cooling plate.

[0013] In one optional embodiment, the cooling plate body has one or at least two main water chambers, with the at least two main water chambers spaced apart; each main water chamber is matched with an opening and a cover plate, each main water chamber is matched with at least two branch water chambers, and each branch water chamber is spaced apart with at least one branch pipe.

[0014] In one alternative embodiment, the shape of the branch pipe matches the shape of the branch water chamber, and the outer periphery of the branch pipe and the branch water chamber form the second flow channel.

[0015] Beneficial effects: The shape of the branch pipe matches the shape of the branch water chamber, which can form a more uniform annular second flow channel, resulting in a more uniform cooling effect.

[0016] In one alternative embodiment, the branch water chamber is a circular hole, an elliptical hole, or an arc-shaped hole that matches the shape and is fitted around the outer periphery of at least two branch pipes.

[0017] In one alternative embodiment, the shape of the main pipe matches the shape of the main water chamber, and the outer surface of the main pipe forms the first flow channel between the main water chamber and the cover plate.

[0018] Beneficial effects: The shape of the main pipe matches the shape of the main water chamber, which can form a more uniform first flow channel and have a more uniform cooling effect.

[0019] In one alternative embodiment, the main water chamber is a circular or elliptical hole.

[0020] In one alternative embodiment, the cooling plate body is made of pure copper or copper alloy material by rolling.

[0021] Beneficial effects: The cooling plate body is made of pure copper or copper alloy material by rolling, which has better thermal conductivity than cast copper and can improve the cooling effect.

[0022] In one alternative embodiment, the main water chamber and the branch water chamber are manufactured by a drilling process.

[0023] In one alternative embodiment, the surface of the piping structure is coated with a heat-insulating material.

[0024] In one alternative embodiment, the piping structure is a stainless steel pipe or a carbon steel pipe. Attached Figure Description

[0038] 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 embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, a copper cooling plate is provided, comprising a cooling plate body 1, a pipe structure 2, and a cover plate 6; the cooling plate body 1 includes a main water chamber 11 and at least two branch water chambers 12, the main water chamber 11 being disposed at the rear end of the cooling plate body 1, and the rear end of the cooling plate body 1 having an opening 13 communicating with the main water chamber 11; one end of each branch water chamber 12 communicating with the main water chamber 11, and the other end extending towards the front end of the cooling plate body 1; the pipe structure 2 includes a main pipe 21 and at least two branch pipes 22 communicating with the main pipe 21, the main pipes 21 being connected to each other. A branch pipe 21 is spaced within the main water chamber 11 and forms a first flow channel 3 with the main water chamber 11; a branch pipe 22 is spaced within the branch water chamber 12 and forms a second flow channel 4 with the branch water chamber 12; the first flow channel 3 and the second flow channel 4 are connected; the main pipe 21 is provided with an inlet 5; the branch pipe 22 is provided with an outlet 23 connected to the second flow channel 4 at one end away from the main pipe 21; a cover plate 6 is sealed and connected to the opening 13; the cover plate 6 is provided with an outlet 7 connected to the main water chamber 11 and a connection port; the connection port is connected to the inlet 5.

[0041] The rear end of the cooling plate body 1 is provided with an opening 13, which facilitates the opening of the main water chamber 11 from the rear end to the front end on the cooling plate body 1 through the opening 13. It also facilitates the even and dense opening of branch water chambers 12 through the opening 13 and the main water chamber 11, resulting in good cooling effect and less damage. At the same time, it is also convenient to connect the pipeline structure 2 to the inside of the cooling plate body 1 through the opening 13. The main pipe 21 and the main water chamber 11 form a first flow channel 3, and the branch pipe 22 and the branch water chamber 12 form a second flow channel 4. The end of the branch pipe 22 away from the main pipe 21 is provided with an outlet 23 that communicates with the second flow channel 4. There is no need to open a hole at the front end of the cooling plate body 1. The heat exchange circulation channel can be formed through the inlet 5, the main pipe 21, the branch pipe 22, the second flow channel 4, the first flow channel 3 and the outlet 7. This avoids the uneven water layout caused by welding plugs to seal the opening at the front end of the copper cooling plate. Each main water chamber 11 can be connected to at least two branch water chambers 12, and each main pipe 21 can be connected to at least two branch pipes 22. Multiple branch water chambers 12 and branch pipes 22 can be evenly arranged to form multiple second flow channels 4, thereby achieving better cooling effect. The cooling effect between each branch pipe 22 and the cooling effect between each second flow channel 4 are also relatively uniform. The cap is sealed at the opening 13 to seal the main water chamber 11 and the branch water chambers 12, preventing coolant from overflowing.

[0042] When the copper cooling plate is working, the coolant enters the main pipe 21 through the inlet 5 on the main pipe 21, and then flows through the main pipe 21 to each branch pipe 22. In the branch pipe 22, the coolant flows from back to front through the outlet 23 to the front end of the cooling plate body 1. Then, the coolant flows back from front to back through the second flow channel 4 between the branch pipe 22 and the branch water chamber 12, and reaches the first flow channel 3 between the main pipe 21 and the main water chamber 11. Finally, the coolant flows out through the outlet 7, forming a heat exchange cycle and carrying away heat. This increases the flow direction of the coolant in the copper cooling plate, extends the flow distance of the coolant in the copper cooling plate, and improves the overall heat exchange effect.

[0043] In a specific embodiment, the cap can be sealed and welded to the opening 13. A water inlet pipe protrudes from the end of the main pipe 21 facing away from the branch pipe 22, and a water inlet 5 is located on the water inlet pipe. A connecting port is fitted around the outer periphery of the water inlet pipe. In a preferred embodiment, a sealing ring is provided between the connecting port and the water inlet pipe. The coolant is cooling water.

[0044] In one embodiment, the outlet 23 is disposed on the end face of the branch pipe 22 facing away from the main pipe 21, and the outlet 23 is spaced apart from the end face of the branch water chamber 12 away from the main water chamber 11.

[0045] The coolant enters the main pipe 21 through the inlet 5 and then enters the branch pipe 22. It directly impacts the end face of the branch pipe 22 that is away from the main pipe 21 through the outlet 23. Since the end face of the branch pipe 22 that is away from the main pipe 21 is close to the front end of the cooling plate body 1, the coolant can directly impact the front end of the cooling plate body 1 and flow back into the second flow channel 4 at the front end, thereby enhancing the heat exchange effect at the front end of the copper cooling plate.

[0046] In one embodiment, the cooling plate body 1 has one or at least two main water chambers 11, and the at least two main water chambers 11 are spaced apart; each main water chamber 11 is matched with an opening 13 and a cover plate 6, each main water chamber 11 is matched with at least two branch water chambers 12, and each branch water chamber 12 is spaced apart with at least one branch pipe 22.
