Description

Technical Field

[0001] This patent relates to the field of waste heat exchange technology, specifically a waste heat exchange and heating device for blast furnace slag flushing water. Background Technology

[0002] In blast furnace production, the blast furnace flushing water contains a large amount of waste heat. Direct discharge does not meet environmental protection requirements, and allowing the blast furnace flushing water to be discharged directly means that the waste heat in the blast furnace flushing water cannot be effectively utilized, which easily leads to resource waste. Existing blast furnace flushing water waste heat exchange devices consist of a water tank and flushing water pipes. However, the flushing water pipes are all long straight pipes located inside the water tank. The flushing water travels in a straight line inside the pipes, with a short path, so the heat exchange effect on the water inside the pipes is poor. Therefore, we propose a blast furnace flushing water waste heat exchange heating device. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this patent is to provide an automatic temperature detection device for exhaust fans. This patent features a bent pipe inside the water tank. By incorporating the bent pipe, the path of the flushing water in the flushing pipe within the water tank is increased, thereby enhancing heat exchange efficiency. Furthermore, the bent pipe is controlled by a motor to move left and right, thus agitating the water in the tank and causing water at different locations to frequently contact the bent pipe, further increasing heat exchange efficiency.

[0004] The technical solution adopted by this patent to solve its technical problem is: a blast furnace slag flushing water waste heat exchange and heating device, including a water tank, a slag flushing water pipe and a motor base. The upper side of the left and right side walls of the water tank are provided with sliding holes. A movable pipe is slidably installed on the inner side wall of the sliding hole. A flexible hose is fixedly installed on the outer end of the movable pipe. The outer end of the flexible hose is fixedly connected to the slag flushing water pipe. A bent pipe is provided inside the water tank. The two ends of the bent pipe are respectively connected to the inner ends of the two movable pipes. Water pipes with switch valves are embedded on the upper and lower sides of the water tank.

[0005] The left end of the motor base is installed on the right side of the water tank. The motor is fixedly installed on the top of the motor base. A disc is fixedly installed on the top of the motor shaft. A connector is connected to the disc. The left end of the connector passes through the right side wall of the water tank and is fixed to the bent pipe.

[0006] The bent tube has mounting holes at all four ends of its sidewall, and copper sheets are fixedly installed on the inner sidewall of each mounting hole.

[0007] Furthermore, the horizontal copper sheet has a first fin integrally formed at one end inside the bent tube, and the vertical copper sheet has a second fin integrally formed at one end inside the bent tube.

[0008] Furthermore, a sealant layer is provided inside the mounting hole.

[0009] Furthermore, a sliding sealing ring is installed on the inner wall of the sliding hole.

[0010] Furthermore, the connecting component includes a swing arm, a T-shaped rod, and a sliding rod. The top right side of the swing arm has a first circular hole, and the bottom end of the T-shaped rod passes through the first circular hole and is fixedly installed on the top left side of the disc. The left end of the swing arm has an integrally formed hinge seat, and a shaft is fixedly installed inside the hinge seat. The top right side of the sliding rod has a second circular hole, which is fitted onto the shaft. The left end of the sliding rod passes through the right through hole of the water tank and is fixedly installed on the bent pipe.

Detailed Implementation

[0018] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0019] See Figure 1 , Figure 2 and Figure 3This is a schematic diagram of the structure of this patent. A waste heat exchange and heating device for blast furnace slag flushing water includes a water tank 1, a slag flushing water pipe 5 and a motor base. The upper side of the left and right side walls of the water tank 1 are provided with sliding holes 2. A movable pipe 3 is slidably installed on the inner side wall of the sliding hole 2. A flexible hose 4 is fixedly installed on the outer end of the movable pipe 3. The outer end of the flexible hose 4 is fixedly connected to the slag flushing water pipe 5. A bent pipe 6 is provided inside the water tank 1. The two ends of the bent pipe 6 are respectively connected to the inner ends of the two movable pipes 3. Water pipes 7 with switch valves are embedded on the upper and lower sides of the water tank 1.

[0020] The left end of the motor base is installed on the right side of the water tank 1. The motor 8 is fixedly installed on the top of the motor base. The top of the rotating shaft of the motor 8 is fixedly installed on the disc 9. The disc 9 is connected to the connector 10. The left end of the connector 10 passes through the right side wall of the water tank 1 and is fixed to the bent pipe 6.

[0021] The motor 8 can drive the bent pipe 6 to move left and right through the connector 10, thereby agitating the water in the water tank 1 and causing the water to frequently come into contact with the bent pipe 6.

[0022] Mounting holes 11 are provided at all four ends of the side wall of the bent pipe 6, and copper sheets 12 are fixedly installed on the inner side wall of each mounting hole 11.

[0023] The copper sheet 12 can be made of pure copper, which has excellent thermal conductivity and is used to increase the heat exchange of the flushing water inside the bent pipe 6.

[0024] Specifically, the horizontal copper sheet 12 has a first fin 13 integrally formed at one end inside the bent tube 6, and the vertical copper sheet 12 has a second fin 14 integrally formed at one end inside the bent tube 6.

[0025] like Figure 2 As shown, the arrangement of the first fin 13 and the second fin 14 is used to increase the contact area between the copper sheet 12 and the slag-flushing water inside the bent pipe 6, and the flow rate of the slag-flushing water can be reduced and buffered by the first fin 13 and the second fin 14, thereby enabling sufficient heat exchange.

[0026] Specifically, a sealant layer 15 is provided inside the mounting hole 11.

[0027] The sealant layer 15 is provided to enhance the sealing effect of the mounting hole 11.

[0028] Specifically, a sliding sealing ring is installed on the inner wall of the sliding hole 2.

[0029] Specifically, the connector 10 includes a rocker arm 16, a T-shaped rod 18, and a slide rod 21. The top right side of the rocker arm 16 is provided with a first circular hole 17. The bottom end of the T-shaped rod 18 passes through the first circular hole 17 and is fixedly installed on the top left side of the disc 9. The left end of the rocker arm 16 is integrally formed with a hinge seat 19. A shaft 20 is fixedly installed inside the hinge seat 19. The top right side of the slide rod 21 is provided with a second circular hole 22. The second circular hole 22 is sleeved on the shaft 20. The left end of the slide rod 21 passes through the right through hole of the water tank 1 and is fixedly installed on the bent pipe 6.

[0030] The inner wall of the through hole on the right side of water tank 1 matches the shape of the inner wall of slide bar 21, so slide bar 21 can only move left and right.

[0031] When the disc 9 rotates, it will cause the swing arm 16 to swing left and right, which in turn will cause the slide rod 21 and the bent tube 6 to move left and right.

[0032] Specifically, a sliding sealing ring is installed in the through hole on the right side of water tank 1.

[0033] Working principle: The flushing water in the flushing water pipe 5 enters the bent pipe 6 and exchanges heat with the water in the water tank 1. At the same time, the motor 8 drives the disc 9 to rotate, which will drive the swing rod 16 to swing left and right, and then drive the slide rod 21 and the bent pipe 6 to move left and right. The movement of the bent pipe 6 will stir the water in the water tank 1, so that the water frequently comes into contact with the bent pipe 6, thereby improving the heat exchange efficiency.

[0034] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent.

However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0035] This patent incorporates a bent pipe within the water tank. This bent pipe increases the travel path of the flushing water within the tank, thereby increasing heat exchange efficiency. Furthermore, the bent pipe is controlled by a motor to move left and right, agitating the water in the tank and causing water at different locations to frequently contact the bent pipe, further enhancing heat exchange efficiency.
