Description

Technical Field

[0001] This utility model relates to the field of medium-frequency heating furnace technology, specifically to a medium-frequency heating furnace shutdown cooling water antifreeze system. Background Technology

[0002] Medium frequency heating furnace is a device that uses the principle of electromagnetic induction to heat metal materials. It is widely used in the field of metal processing, such as forging, casting, and heat treatment.

[0003] The existing medium-frequency heating furnace equipment has a major problem during use: it does not have antifreeze protection for cooling water in winter. As a result, when the medium-frequency heating furnace is shut down in winter, the internal cooling water is very likely to freeze, which affects the normal operation of the medium-frequency heating furnace. Secondly, the existing medium-frequency heating furnace equipment also has the problem of not being able to securely connect the circulation pipe to the liquid outlet. As a result, the connection between the circulation pipe and the liquid outlet is very easy to separate, which leads to the waste of cooling water and prevents the cooling water from circulating. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cooling water antifreeze system for medium-frequency heating furnace shutdown, which has the advantages of cooling water antifreeze and stable connection between the circulation pipe and the liquid outlet, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a cooling water antifreeze system for a medium-frequency heating furnace, comprising a frame, a temperature sensor on the inner wall of the frame, a support leg fixedly installed at the bottom of the frame, a cylinder fixedly installed on the inner wall of the support leg, a liquid outlet at the top of the cylinder, a circulation pipe one and a circulation pipe two at the outer end of the liquid outlet, the ends of the circulation pipe one and the circulation pipe two away from the liquid outlet being fixedly installed on the inner wall of a heating tank, a circulation pump fixedly placed on the inner wall of the heating tank, a slot being formed at the end of the circulation pipe one and the circulation pipe two near the liquid outlet, a sliding groove being formed on the outer edge of the liquid outlet, a spring being provided on the inner wall of the sliding groove, a slider being fixedly installed on the extension end of the spring, and a locking block being fixedly installed on the outer side of the slider.

[0006] As a preferred technical solution of this utility model: the top of the frame is provided with a top cover, and the bottom of the heating barrel and the bottom of the support leg are on the same horizontal plane.

[0007] As a preferred technical solution of this utility model: a controller is fixedly installed on the outside of the frame, and the heating tank, the circulating pump, and the temperature sensor are all electrically connected to the controller.

[0008] As a preferred technical solution of this utility model: the shape of the card block is adapted to the shape of the card slot, and the card block is slidably connected to the inner wall of the card slot.

[0009] As a preferred technical solution of this utility model: a connecting pipe one is provided at the bottom of the square frame, and a connecting pipe two is provided on the outer edge of the cylinder. The end of the connecting pipe one away from the square frame is fixedly installed with the connecting pipe two.

[0010] As a preferred technical solution of this utility model: the inner wall of the slide groove is provided with a limiting groove, the inner wall of the limiting groove is slidably connected to a limiting block, and the limiting block is fixedly installed on the outer side of the slider.

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

[0012] 1. The cooling water antifreeze system for this medium-frequency heating furnace utilizes a temperature sensor and a circulating pump. The top cover can be opened by rotating it, allowing liquid to be injected into the interior of a rectangular frame. The liquid inside the frame flows into a cylinder through a connecting pipe, and then through the cylinder and a second circulating pipe into the heating tank. A temperature sensor fixedly installed at the bottom of the inner wall of the frame senses the temperature of the liquid inside. When the liquid temperature inside the frame drops below the temperature of the second circulating pipe, the temperature sensor sends a feedback to the controller. The controller then activates the heating tank, heating the liquid circulating inside and thus preventing it from freezing.

[0013] 2. The antifreeze system for cooling water during shutdown of this medium-frequency heating furnace utilizes the cooperation of a locking block and a locking slot. When it is necessary to connect circulation pipe one and circulation pipe two to the liquid outlet, pressing the slider deforms the spring. At this time, the limiting block on the outside of the slider slides inward on the inner wall of the limiting groove, limiting the slider. Through the sliding of the slider, the locking block is retracted into the inner wall of the groove. Then, circulation pipe one or circulation pipe two is inserted into the outer edge of the liquid outlet. When the locking slot on the inner wall of circulation pipe one or circulation pipe two coincides with the locking block, the locking block will engage with the locking slot through the release of the elastic potential energy of the spring. At this time, the liquid outlet and circulation pipe one or circulation pipe two are restricted and fixed, preventing the liquid outlet from separating from circulation pipe one or circulation pipe two.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 The intermediate frequency heating furnace shutdown cooling water antifreeze system includes a frame 1. A temperature sensor 10 is installed on the inner wall of the frame 1. A support leg 3 is fixedly installed at the bottom of the frame 1. A cylinder 4 is fixedly installed on the inner wall of the support leg 3. A liquid outlet 11 is provided at the top of the cylinder 4. A circulation pipe 5 and a circulation pipe 6 are provided at the outer end of the liquid outlet 11. The ends of the circulation pipes 5 and 6 away from the liquid outlet 11 are fixedly installed on the inner wall of the heating tank 7. A circulation pump 9 is fixedly placed on the inner wall of the heating tank 7. A slot 15 is opened at the end of the circulation pipes 5 and 6 near the liquid outlet 11. A sliding groove 12 is opened on the outer edge of the liquid outlet 11. A spring 13 is provided on the inner wall of the sliding groove 12. A slider 16 is fixedly installed at the extended end of the spring 13. A locking block 14 is fixedly installed on the outer side of the slider 16.

[0023] In the above structure, the temperature sensor 10 and the circulation pump 9 work together to open the top cover 2 by rotating it, and then inject liquid into the interior of the frame 1. The liquid inside the frame 1 flows into the cylinder 4 through the connecting pipe 17, and then flows into the heating tank 7 through the circulation pipe 6. The temperature sensor 10, which is fixedly installed at the bottom of the inner wall of the frame 1, can sense the temperature of the liquid inside the frame 1. When the temperature of the liquid inside the frame 1 is lower than that of the circulation pipe 6, the temperature sensor 10 will feed the result back to the controller 8. The controller 8 will control the heating tank 7 to work, and use the heating tank 7 to heat the liquid circulating inside the heating tank 7, thereby achieving the purpose of preventing the liquid from freezing.

[0024] In a preferred embodiment: a top cover 2 is provided on the top of the frame 1, and the bottom of the heating barrel 7 is at the same level as the bottom of the support leg 3.

[0025] In the above structure, the top cover 2 facilitates the injection of liquid.

[0026] In a preferred embodiment: a controller 8 is fixedly installed on the outside of the frame 1, and the heating tank 7, the circulation pump 9, and the temperature sensor 10 are all electrically connected to the controller 8.

[0027] In the above structure, the controller 8 can be used to control the heating tank 7, the circulation pump 9, and the temperature sensor 10 to work or stop working.

[0028] In a preferred embodiment, the shape of the card block 14 is adapted to the shape of the card slot 15, and the card block 14 is slidably connected to the inner wall of the card slot 15.

[0029] In the above structure, through the cooperation of the locking block 14 and the locking groove 15, when it is necessary to connect the first circulation pipe 5 and the second circulation pipe 6 with the liquid outlet 11, the slider 16 can be pressed to compress and deform the spring 13. At this time, the limiting block 20 on the outside of the slider 16 will slide inward on the inner wall of the limiting groove 19 to limit the slider 16. Through the sliding of the slider 16, the locking block 14 is retracted into the inner wall of the sliding groove 12. Then, the first circulation pipe 5 or the second circulation pipe 6 is inserted into the outer edge of the liquid outlet 11. When the locking groove 15 opened on the inner wall of the first circulation pipe 5 or the second circulation pipe 6 coincides with the locking block 14, the locking block 14 will lock with the locking groove 15 through the release of the elastic potential energy of the spring 13. At this time, the liquid outlet 11 and the first circulation pipe 5 or the second circulation pipe 6 are restricted and fixed to prevent the liquid outlet 11 from separating from the first circulation pipe 5 or the second circulation pipe 6.

[0030] In a preferred embodiment: a connecting pipe 17 is provided at the bottom of the frame 1, and a connecting pipe 2 18 is provided on the outer edge of the cylinder 4. The end of the connecting pipe 17 away from the frame 1 is fixedly installed with the connecting pipe 2 18.

[0031] In the above structure, the connection pipe 17 and the connection pipe 18 facilitate the circulation of liquid inside the frame 1 within the inner walls of the frame 1 and the heating tank 7.

[0032] In a preferred embodiment: a limiting groove 19 is formed on the inner wall of the slide 12, and a limiting block 20 is slidably connected to the inner wall of the limiting groove 19. The limiting block 20 is fixedly installed on the outer side of the slider 16.

[0033] In the above structure, the sliding of the slider 16 can be limited by the cooperation of the limiting groove 19 and the limiting block 20, so as to avoid instability caused by the spring 13.

[0034] Working Principle: When this device is needed, the temperature sensor 10 and the circulation pump 9 work together. Then, the top cover 2 is opened by rotating it, allowing liquid to be injected into the box 1. The liquid inside the box 1 flows into the cylinder 4 through the connecting pipe 17, and then through the cylinder 4 and the circulation pipe 6 into the heating tank 7. The temperature sensor 10, fixedly installed at the bottom of the inner wall of the box 1, senses the temperature of the liquid inside the box 1. When the temperature of the liquid inside the box 1 is lower than that of the circulation pipe 6, the temperature sensor 10 sends the result back to the controller 8. The controller 8 then controls the heating tank 7 to operate, heating the liquid circulating inside the heating tank 7 to achieve antifreeze properties. Secondly, the cooperation of the locking block 14 and the locking slot 15 further... When it is necessary to connect circulation pipe 5 and circulation pipe 6 to liquid outlet 11, the slider 16 can be pressed to compress and deform the spring 13. At this time, the limiting block 20 on the outside of the slider 16 will slide inward on the inner wall of the limiting groove 19 to limit the slider 16. Through the sliding of the slider 16, the locking block 14 will be housed in the inner wall of the slide groove 12. Then, circulation pipe 5 or circulation pipe 6 is inserted into the outer edge of liquid outlet 11. When the locking groove 15 opened on the inner wall of circulation pipe 5 or circulation pipe 6 coincides with the locking block 14, the locking block 14 will lock with the locking groove 15 through the release of the elastic potential energy of the spring 13. At this time, liquid outlet 11 and circulation pipe 5 or circulation pipe 6 are restricted and fixed to prevent the liquid outlet 11 from separating from circulation pipe 5 or circulation pipe 6.
