[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] Specifically, it refers to an automatic temperature-regulating heating system using circulating water for cooling an electric arc furnace, including a circulating water tank 1, an electric arc furnace 2, a first water pump 3, a floor heating pipe 4, and two second water pumps 5. A first circulating pipe is provided between the circulating water tank 1 and the cooling system of the electric arc furnace 2. The first water pump 3 is located in the input pipe of the first circulating pipe. The first water pump 3 can draw cooling water from the circulating water tank 1 to the cooling system of the electric arc furnace 2. The water that has passed through the cooling system is finally reintroduced into the circulating water tank 1.

[0025] Multiple V-shaped heat-conducting pipes 7 are installed in the circulating water tank 1. The V-shaped heat-conducting pipes 7 are galvanized pipes. A second circulation pipeline is set between the multiple V-shaped heat-conducting pipes 7 and the underfloor heating pipeline 4. Two second water pumps 5 are installed in the input pipeline of the second circulation pipeline. When the second water pumps 5 are started, water can be drawn and flow in the second circulation pipeline. After passing through the V-shaped heat-conducting pipes 7, the water can absorb heat from the circulating water tank 1. The heated water is then transported to the underfloor heating pipeline 4 to provide heating for the living area. The water after passing through the underfloor heating pipeline 4 is finally reintroduced into the circulating water tank 1, thereby saving electricity costs and truly achieving energy conservation, emission reduction, and green production.

[0026] A first temperature sensor 8 is installed on the side of the output pipe of the second circulation pipeline near the circulating water tank 1. The first temperature sensor 8 is connected to a PLC controller that can control the second water pump 5. When the first temperature sensor 8 detects that the return water temperature of the underfloor heating pipe 4 is high, the second water pump 5 can automatically adjust the water inlet size to make the temperature of the living area reach a suitable temperature.

[0027] A cooler 6 is installed in the circulating water tank 1, and a second temperature sensor 9 is installed on the circulating water tank 1. Both the cooler 6 and the second temperature sensor 9 are connected to the PLC controller. The second temperature sensor 9 can monitor the temperature change in the circulating water tank 1 in real time. When the temperature is too high, the cooler 6 is activated to reduce the temperature in the circulating water tank 1, so that the temperature in the circulating water tank 1 is between 30 and 60 degrees Celsius. This avoids the temperature from being too high and affecting the stable operation of the electric arc furnace, and also ensures that the temperature in the living area reaches a suitable level.

[0028] A riser pipe 10 is installed on the inner wall of the circulating water tank 1. The output pipe of the first circulation pipeline is connected to the inside of the riser pipe 10 at one end near the circulating water tank 1. A rotating shaft 11 is installed inside the riser pipe 10. A screw conveyor blade 12 is installed on the outer surface of the rotating shaft 11. The outer surface of the screw conveyor blade 12 is in contact with the inner wall of the riser pipe 10. Multiple filter holes 13 are opened on the screw conveyor blade 12.

[0029] When in use, the rotating shaft 11 rotates, and the auger blades 12 rotate synchronously with the rotating shaft 11. When the cooling water from the cooling system of the electric arc furnace 2 is first input into the riser pipe 10, the rotating shaft 11 rotates, and the auger blades 12 rotate synchronously with the rotating shaft 11. The cooling water flows downward through the filter holes 13 after passing through the auger blades 12 to the circulating water pool 1, while the filtered impurities are transported upward under the rotation of the auger blades 12.

[0030] The upper end of the lift pipe 10 extends out of the upper side of the circulating water tank 1. A collection housing 14 is provided on the upper side of the lift pipe 10. An inclined block 15 is provided on the bottom wall of the collection housing 14. The upper end of the lift pipe 10 passes through the inclined surface of the inclined block 15. A drawer 16 is slidably connected to the bottom wall of the collection housing 14. One side of the drawer 16 slidably passes through the outside of the collection housing 14. The upper surface of one side of the drawer 16 is flush with the inclined bottom surface of the inclined block 15. The upper end of the rotating shaft 11 and the upper side of the auger blade 12 both extend out of the lift pipe 10. The upper end of the rotating shaft 11 is rotatably connected to the top wall of the collection housing 14. A motor for controlling the rotation of the rotating shaft 11 is provided on the upper surface of the collection housing 14. Therefore, after the impurities filtered on the auger blade 12 are conveyed upward out of the lift pipe 10, these impurities can be thrown out onto the inclined surface of the inclined block 15 under the action of inertia. These impurities slide down along the inclined surface of the inclined block 15 into the drawer 16, thereby collecting these impurities.

[0031] A striking assembly is provided on each of the four inner walls of the collection housing 14. The striking assembly includes a mounting base 17, which is located on the inner wall of the collection housing 14. A rotating plate 18 is rotatably connected to the mounting base 17. A striking ball 20 is provided on the lower side of the rotating plate 18 near the inclined block 15, which can strike the inclined surface of the inclined block 15. A striking block 19 is provided on the upper side of the rotating plate 18, which can strike the inner wall of the collection housing 14.

[0032] In use, by controlling the rotation of the rotating plate 18, the rotating plate 18 can drive the striking ball 20 to strike the inclined block 15 to strike the inclined surface and the striking block 19 to strike the inner wall of the collection housing 14. Therefore, impurities that fall on the inclined block 15 or the inner wall of the collection housing 14 are more likely to fall into the drawer 16 under the action of vibration, thus improving the collection effect of impurities.

[0033] A cam 21 is fitted on the outer surface of the upper end of the rotating shaft 11. Four sliding seats 22 are provided on the top wall of the collecting housing 14. Push rods 23 are slidably fitted on the sliding seats 22. One end of the push rod 23 contacts the surface of the cam 21 and slides, while the other end of the push rod 23 contacts the upper side of the rotating plate 18. A sleeve plate 24 is fitted on the outer surface of the push rod 23. A spring 25 is movably fitted on the outer surface of the push rod 23 between the sleeve plate 24 and the sliding seat 22.

[0034] When in use, as the rotating shaft 11 rotates, the cam 21 rotates synchronously with the rotating shaft 11. The cam 21 can generate a thrust on the push rod 23, so that the push rod 23 generates a thrust on the upper side of the rotating plate 18. At the same time, the spring 25 is squeezed and contracted by the sleeve plate 24. When the end of the cam 21 contacts the push rod 23, the spring 25 returns to its original position, and the rotating plate 18 rotates back to a vertical position under the action of inertia, so that the rotating plate 18 rotates back and forth.

[0035] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
