[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] For ease of understanding, the cooling tower is explained here: the cooling tower includes a cooling water pipe 10 arranged in a serpentine shape, and a water tank 11 located at the bottom of the cooling water pipe 10. When the cooling water in the electric furnace appliance flows into the cooling water pipe 10 in the cooling tower, since the cooling water pipe 10 is a serpentine device, the cooling water gradually cools down during the internal flow, and then flows into the water tank 11. The water in the water tank 11 meets the cooling water demand of the electric furnace appliance and can be used for the cooling process of the electric furnace appliance.

[0037] Please also read Figures 1 to 4 Now, the water antifreeze device for electric furnace appliances provided by the utility model is described. The water antifreeze device for electric furnace electrical appliances is used for a cooling tower, and comprises a first water inlet pipe 20, a second water inlet pipe 30, two switch valves 40, a liquid level gauge 50 and a steam device 60, wherein the first water inlet pipe 20 is communicated with a water tank 11; the second water inlet pipe 30 is communicated with an external water pipe; the two switch valves 40 are respectively arranged on the first water inlet pipe 20 and the second water inlet pipe 30, and one of the two switch valves 40 is opened; the liquid level gauge 50 is arranged in the water tank 11, and the liquid level gauge 50 is communicatively connected with the two switch valves 40; the steam device 60 is located in the middle of the cooling water pipe 10, and the steam device 60 comprises a steam pipe 61, and a plurality of air outlets located at the top and the bottom of the steam pipe 61, and the steam pipe 61 is parallel to the horizontal direction; wherein, when the reading of the liquid level gauge 50 is lower than a preset value, the switch valve 40 on the second water inlet pipe 30 is opened, and when the reading of the liquid level gauge 50 is equal to or greater than the preset value, the switch valve 40 on the first water inlet pipe 20 is opened.

[0038] It is easy to imagine that the steam equipment 60 also needs a water pump that can extract water from the water tank 11, and a heater that converts the water in the first water inlet pipe 20 or the second water inlet pipe 30 into steam, etc. These are all existing technologies and the specific structure will not be described in detail here.

[0039] Compared with the prior art, the water antifreeze device for electric furnace appliances provided in the present embodiment is that the water cooled by the cooling water pipe 10 will be stored in the water tank 11. There will be a certain amount of water stored in the water tank 11. When the liquid level meter 50 detects that the water in the water tank 11 meets the demand, the switch valve 40 on the first water inlet pipe 20 is opened, and the switch valve 40 on the second water inlet pipe 30 is closed. The water in the water tank 11 is extracted and converted into steam to provide steam for the cooling water pipe 10, so as to prevent the cooling water pipe 10 from freezing or cracking. When the liquid level meter 50 detects that the water in the water tank 11 is lower than the preset value, it means that the water in the water tank 11 can only maintain the cooling water supply to the electric furnace appliances. At this time, the switch valve 40 on the first water inlet pipe 20 is closed, and the switch valve 40 on the second water inlet pipe 30 is opened, and the steam pipe 61 sprays steam to heat the cooling water pipe 10. The utility model discloses an electric furnace electrical appliance water antifreeze device, which heats the cooling water pipe 10 through the steam device 60, so as to prevent the cooling water pipe 10 from freezing or cracking. There is no need to repair or replace the cooling water pipe 10 during the next production, thereby improving the production efficiency and reducing the cost loss. The cooling water pipe 10 is heated by steam, which is lower in cost and more effective than directly using an electric heating pipe. The steam is sprayed on the outer wall of the cooling water pipe 10, and can drip into the water tank 11 after condensation. When the water in the water tank 11 is sufficient, an external water source is not used. The process can realize the recycling of the water in the water tank 11, reduce the waste of water, and reduce the production cost.

[0040] In some embodiments, an improved implementation of the above-mentioned electric furnace electrical appliance water antifreeze device can be adopted as follows Figure 1 See the structure shown. Figure 1 , further comprising a temperature sensor 70, which is disposed in the cooling tower and is in communication with the steam device 60; wherein, when the reading of the temperature sensor 70 is lower than a preset value, the steam device 60 is turned on; and when the reading of the temperature sensor 70 is equal to or greater than the preset value, the steam device 60 is turned off. When the temperature in the cooling tower is lower than the preset value, the cooling water pipe 10 will freeze or crack, so the temperature in the cooling tower is monitored in real time through the temperature sensor 70 to avoid the steam device 60 from being started by mistake when the temperature is high, thereby avoiding unnecessary energy waste.

[0041] It should be noted that the preset value corresponding to the temperature sensor 70 is different from the preset value corresponding to the liquid level meter 50. Although they are called the same, the preset value corresponding to the temperature sensor 70 and the preset value corresponding to the liquid level meter 50 are two completely different values ​​depending on the specific usage.

[0042] Specifically, when the reading of the temperature sensor 70 is higher than the preset value, the steam device 60 is not turned on, the corresponding switch valve 40 is not turned on, and the entire antifreeze device is in an inoperative state.

[0043] In specific implementation, the temperature sensor 70 and the liquid level meter 50 can be connected to a control device (such as a computer, a mobile phone, etc.), and the temperature and liquid level conditions can be viewed in real time in the control device. When the temperature data and the liquid level data reach the corresponding preset values, the control device can automatically control the opening and closing of the switch valve 40 or the steam device 60.

[0044] In some embodiments, an improved implementation of the above-mentioned air outlet can be adopted as follows Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The multiple air outlets at the top and the multiple air outlets at the bottom are staggered along the axial direction of the steam pipe 61. The air outlets at the top and at the bottom are alternately distributed, which can optimize the antifreeze effect on the cooling water pipe 10.

[0045] Specifically, according to actual conditions, the number of air outlets at the top may be different from the number of air outlets at the bottom; for example, in actual production, the cooling water pipes 10 of the top plate are more likely to freeze, so the number of air outlets at the top may be greater than the number of air outlets at the bottom.

[0046] In some embodiments, an improved implementation of the cooling water pipe 10 can be as follows: Figure 1 See the structure shown. Figure 1 A guide bar 12 is provided at the bottom of the cooling water pipe 10. The guide bar 12 is a conical structure with the tip facing downward. After the steam is ejected, it will adhere to the outer wall of the cooling water pipe 10. The guide bar 12 can accelerate the dripping of the condensed steam. The condensed steam drips into the water tank 11 and can be used again for the electric furnace appliance or the steam equipment 60.

[0047] In some embodiments, an improved implementation of the steam pipe 61 can be as follows: Figure 1 , Figure 3 to Figure 4 See the structure shown. Figure 1 , Figure 3 to Figure 4 The steam pipe 61 is provided with a plurality of joints 62, which are threadedly connected to the steam pipe 61. The joints 62 are cylindrical and perpendicular to the steam pipe 61. The plurality of gas outlets are provided on the plurality of joints 62 and correspond to each other. The joints 62 are threadedly connected to the steam pipe 61 for easy disassembly, and the number of gas outlets at the top or bottom can be adjusted according to different situations, which is convenient for use. The joints 62 are easy to disassemble and can be replaced and cleaned at any time.

[0048] Specifically, in order to ensure the sealing between the joint 62 and the steam pipe 61 , a sealing ring 63 is sleeved on the outer periphery of the joint 62 to prevent air leakage at the connection between the joint 62 and the steam pipe 61 .

[0049] In some embodiments, an improved embodiment of the above-mentioned joint 62 can be adopted as follows Figure 4 See the structure shown. Figure 4 The joint 62 also includes a mesh plate 64 that is snap-fitted with the air outlet. The mesh plate 64 can make the ejected steam appear in multiple strands, increase the coverage of the steam, and improve the antifreeze effect on the cooling water pipe 10.

[0050] In some embodiments, an improved implementation of the first water inlet pipe 20 can be as follows: Figure 2 See the structure shown. Figure 2 The water inlet end of the first water inlet pipe 20 is provided with a conical cover 21, the small end of the conical cover 21 is fixedly connected to the first water inlet pipe 20, and the large end of the conical cover 21 is provided with a filter 22, and the large end of the conical cover 21 faces the bottom of the water tank 11. Since the water tank 11 is open and stores cooling water for a long time, there will be impurities at the bottom. When the first water inlet pipe 20 is filled with water, the impurities in the water tank 11 are filtered through the filter 22, which can prevent the impurities from entering the steam equipment 60 and causing blockage or damage to the steam equipment 60.

[0051] In some embodiments, an improved implementation of the filter screen 22 can be as follows: Figure 2 See the structure shown. Figure 2 The outer edge of the filter 22 is provided with a circle of elastic rope 23, and the elastic rope 23 is sleeved on the outer periphery of the conical cover 21. The filter 22 can be directly sleeved on the conical cover 21, which is convenient for installation, more flexible in use, and can be replaced regularly.

[0052] In some embodiments, an improved implementation of the steam pipe 61 can be as follows: Figure 3 to Figure 4 See the structure shown. Figure 3 to Figure 4 The steam pipe 61 includes a shell 611 and a detachable pipe 612 clamped inside the shell 611. The detachable pipe 612 is respectively connected to the first water inlet pipe 20, the second water inlet pipe 30 and a plurality of air outlets. Since the steam pipe 61 is supplied with high-temperature steam for a long time, scale may be attached to the inner wall of the steam pipe 61 during the process of heating water. By providing the detachable pipe 612, the detachable pipe 612 can be replaced regularly to avoid the blockage of the air outlet; and since the joint 62 is detachably connected to the steam pipe 61, the replacement of the detachable pipe 612 is more convenient.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
