Description

Technical Field

[0001] This utility model relates to the field of medium-frequency induction furnace technology, and in particular to a water-cooled pipeline structure for a medium-frequency induction furnace. Background Technology

[0002] Medium-frequency induction furnaces utilize the principle of induction heating. Alternating current flows through a coil, causing a change in the magnetic field, which in turn heats the metal. However, the structural components of an induction furnace are mostly made of metal. During induction heating, the energized body and nearby metal structural components generate heat. For safety reasons, the coil, relay, and water-cooled cables need to be cooled. Therefore, current medium-frequency induction furnaces are equipped with water-cooling pipes. Cooling water is supplied to these pipes, which cools the coil, relay, and water-cooled cables.

[0003] Currently, cooling water for coils, relays, and water-cooled cables is collected from the rear of the furnace body via rubber hoses connected to a manifold on the side of the furnace body and distributed to various branches in each water-cooled pipeline, providing cooling water for the coils, relays, and water-cooled cables. However, with a larger furnace power, the water flow required for the coils, relays, and water-cooled cables will also be relatively large, and the number of rubber hoses and branches required will also be greater, making the on-site connection of rubber hoses quite cumbersome. In addition, the fact that all the rubber hoses are concentrated at the rear of the furnace body causes them to pile up, making the overall work less neat and convenient. Utility Model Content

[0004] The purpose of this utility model is to provide a water-cooled pipeline structure for a medium-frequency induction furnace, which aims to solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a water-cooled pipeline structure for a medium-frequency induction furnace, including a furnace base, a medium-frequency induction furnace body rotatably mounted on the furnace base via a fulcrum shaft, and a water-cooled pipeline disposed on the medium-frequency induction furnace body.

[0007] A water manifold is installed on the medium-frequency induction furnace body. The water manifold is connected to the water-cooling pipeline and is used to supply cooling water to the water-cooling pipeline.

[0008] A first water inlet pipe is fixedly installed on the side of the medium frequency induction furnace body. The first end of the first water inlet pipe is connected to the water distribution device. The second end of the first water inlet pipe is located at the position of the fulcrum shaft. A rotary joint is rotatably installed on the second end of the first water inlet pipe. A second water inlet pipe is connected to the rotary joint.

[0009] In one possible implementation, one end of the rotary joint one is connected with the first water inlet pipe, and the other end is arranged downward;

[0010] The first end of the second water inlet pipe is installed to the bottom of the rotary joint one, and the second water inlet pipe is arranged at the side of the intermediate frequency induction furnace body.

[0011] In one possible implementation, the side of the intermediate frequency induction furnace body is installed with a mounting bracket for mounting the first water inlet pipe, and the first water inlet pipe is mounted to the mounting bracket through a locking ring.

[0012] In one possible implementation, the bottom of the second water inlet pipe is installed with a positioning bracket.

[0013] In one possible implementation, the second water inlet pipe comprises a flexible pipe body and a steel pipe body, the first end of the flexible pipe body is connected to the rotary joint one, and the second end of the flexible pipe body is connected with the first end of the steel pipe body.

[0014] In one possible implementation, the first water inlet pipe is a steel pipe.

[0015] In one possible implementation, the rotary joint one is L-shaped.

[0016] In one possible implementation, the other side of the intermediate frequency induction furnace body is fixedly installed with a first water return pipe, the first end of the first water return pipe is connected with the water collector, the second end of the first water return pipe is located at the position of the fulcrum shaft, the rotary joint two is rotatably installed on the second end of the first water return pipe, and the second water return pipe is connected with the rotary joint two.

[0017] In summary, due to the adoption of the above technical scheme, the present application has the following advantages:

[0018] In the present application, only the second water inlet pipe and the first water inlet pipe constitute a branch pipe on one side of the intermediate frequency induction furnace body, so that cooling water can be supplied to the water cooling pipe in the intermediate frequency induction furnace body. Compared with the prior art of supplying cooling water through a plurality of rubber hoses, the overall structure is more convenient to install, the number of pipes is less, and the installation time of the pipes is saved. In addition, by installing the rotary joint one to the position of the fulcrum shaft, the rear part of the intermediate frequency induction furnace body does not have too many water pipes accumulated, so that the rear part of the intermediate frequency induction furnace body is more tidy and convenient.

[0029] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with the accompanying drawings.

[0030] First, use Figures 1-3 The overall structure of the water-cooled pipe structure for medium frequency induction furnace is described, Figure 1 It is the structure schematic view of the utility model. Figure 2 It is the three-dimensional schematic view of the utility model. Figure 3 It is the schematic view of the medium frequency induction furnace body 1 overturning in the utility model.

[0031] The water-cooled pipe structure for medium frequency induction furnace includes furnace seat 100, medium frequency induction furnace body 1 and water-cooled pipe line. One end of medium frequency induction furnace body 1 is rotatably installed to furnace seat 100 through fulcrum shaft 101, and medium frequency induction furnace body 1 can be overturned through fulcrum shaft 101 to pour the material in medium frequency induction furnace body 1 to the outside. The water-cooled pipe line is arranged on medium frequency induction furnace body 1, and the water-cooled pipe line is used to supply cooling water to coil, relay iron and water-cooled cable to cool coil, relay iron and water-cooled cable. The water-cooled pipe line is prior art, and will not be described in detail here.

[0032] The water collecting and distributing device 2 is installed on medium frequency induction furnace body 1, and the water collecting and distributing device 2 includes water collector and water distributor, and the water collecting and distributing device 2 is connected with water-cooled pipe line, specifically, the water distributor in water collecting and distributing device 2 is connected with water-cooled pipe line. When cooling water is supplied to water collecting and distributing device 2, water collecting and distributing device 2 can supply cooling water to water-cooled pipe line.

[0033] A first water inlet pipe 3 is fixedly installed on the side of the medium-frequency induction furnace body 1. The first end of the first water inlet pipe 3 is connected to the water distribution unit 2. Specifically, the water distributor in the water distribution unit 2 is connected to the first end of the first water inlet pipe 3. The second end of the first water inlet pipe 3 is located at the position of the fulcrum shaft 101, and a rotary joint 301 is rotatably installed on the second end of the first water inlet pipe 3. A second water inlet pipe 4 is connected to the rotary joint 301.

[0034] In order to cope with the coil cooling of the high-power furnace body and meet the flow of large-flow cooling water, both the first water inlet pipe 3 and the second water inlet pipe 4 can be made of large-specification steel pipes.

[0035] When cooling water is supplied to the manifold 2 through the second inlet pipe 4, the cooling water can be supplied to the manifold 2 along the second inlet pipe 4, the rotary joint 301 and the first inlet pipe 3. Then the manifold 2 supplies the cooling water to each branch of the water-cooled pipeline, thereby cooling the coil, relay iron and water-cooled cable.

[0036] In this embodiment, through the cooperation of the second water inlet pipe 4, the rotary joint 301, the first water inlet pipe 3, and the water manifold 2, only one branch pipe is needed on one side of the medium-frequency induction furnace body 1 to supply cooling water to the water-cooled pipes in the medium-frequency induction furnace body 1. Compared with the existing method of supplying cooling water through several rubber hoses, the overall structure is more convenient to install, has fewer pipes, and saves installation time. On the other hand, by installing the rotary joint 301 at the position of the fulcrum shaft 101, too many water pipes will not accumulate at the rear of the medium-frequency induction furnace body 1, thus making the rear of the medium-frequency induction furnace body 1 neater and more convenient.

[0037] When the medium frequency induction furnace body 1 rotates on the furnace base 100 via the fulcrum shaft 101, the rotary joint 301 ensures that the rotation of the medium frequency induction furnace body 1 does not affect the use of the second water inlet pipe 4 and the first water inlet pipe 3.

[0038] In some embodiments, such as Figure 2 As shown, Figure 2 This is a three-dimensional schematic diagram of the present utility model. Regarding the specific structure of the rotary joint 301, the rotary joint 301 is L-shaped, one end of the rotary joint 301 is connected to the first water inlet pipe 3, and the other end of the rotary joint 301 can be set downward.

[0039] The first end of the second water inlet pipe 4 is installed to the bottom of the rotary joint 301. The second water inlet pipe 4 is located on the side of the medium frequency induction furnace body 1. A positioning bracket 6 is installed at the bottom of the second water inlet pipe 4. The bottom of the positioning bracket 6 can be installed on the ground 7 next to the furnace base 100. In this embodiment, the second water inlet pipe 4 can be fixedly installed to the side of the medium frequency induction furnace body 1 by means of the positioning bracket 6.

[0040] In some embodiments, as Figure 2 shown, Figure 2 is a three-dimensional schematic view of the utility model. The other side of the intermediate frequency induction furnace body 1 is fixedly installed with a first backwater pipe 8, the first end of the first backwater pipe 8 is communicated with the water collector 2, specifically, the first end of the first backwater pipe 8 is communicated with the water collector in the water collector 2, for circulating and discharging the cooling water in the water cooling pipe. The second end of the first backwater pipe 8 is located at the position of the fulcrum shaft 101, and a rotary joint two 801 is rotatably installed on the second end of the first backwater pipe 8, and a second backwater pipe 9 is connected to the rotary joint two 801. In the present embodiment, the cooling water can be circulated and discharged through the water collector in the water collector 2, the first backwater pipe 8, the rotary joint two 801 and the second backwater pipe 9, and the water discharge structure and the water supply structure (the first water inlet pipe 3, the rotary joint one 301 and the second water inlet pipe 4) at the first backwater pipe 8, the rotary joint two 801 and the second backwater pipe 9 are completely same in principle, the difference is only one water inlet, the other water discharge.

[0041] In some embodiments, as Figure 2 shown, Figure 2 is a three-dimensional schematic view of the utility model. Regarding the mounting structure of the first water inlet pipe 3, the side of the intermediate frequency induction furnace body 1 is installed with a mounting bracket 5 for mounting the first water inlet pipe 3, and the first water inlet pipe 3 is mounted to the mounting bracket 5 by a lock ring. In the present embodiment, the first water inlet pipe 3 can be stably fixedly mounted to the intermediate frequency induction furnace body 1 by the mounting bracket 5.

[0042] In some embodiments, as Figure 2 shown, Figure 2 is a three-dimensional schematic view of the utility model. Regarding the specific structure of the second water inlet pipe 4, the second water inlet pipe 4 can include a flexible pipe body 401 and a steel pipe body 402, the first end of the flexible pipe body 401 is connected to the rotary joint one 301, and the second end of the flexible pipe body 401 is connected to the first end of the steel pipe body 402. In the present embodiment, because the rotary joint one 301 and the fulcrum shaft 101 are not absolutely concentric, the flexible pipe body 401 has a certain flexibility and flexibility, which can solve the problem that the rotary joint one 301 and the fulcrum shaft 101 are not absolutely concentric.
