[0003] Currently, the temperature of the sintering mixture trough steam preheating device can be effectively increased and the sintering production rate can be improved. However, when the steam in the sintering mixture trough steam preheating device is transported in the steam pipe, some heat may be lost, resulting in a decrease in the temperature level of the mixture and thus reducing the output. To solve the above problems, a new type of sintering mixture trough steam preheating device that can insulate the steam pipe is needed. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that when the steam in the sintering mixture trough steam preheating device is transported in the steam pipe, some heat may be lost, resulting in a decrease in the temperature level of the mixture and thus reducing production. Therefore, a new type of sintering mixture trough steam preheating device is proposed.

[0015] One end of the connecting pipe is fixedly connected to a gas storage shell, a first steam nozzle is fixedly connected to one side of the gas storage shell, and a second steam nozzle is fixedly connected to one side of the gas storage shell.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0017] 1. In this utility model, an insulation pipe is installed, and insulation cotton is placed inside the insulation pipe. The steam pipe is located inside the insulation cotton. During use, the insulation cotton and the insulation pipe protect the steam pipe from heat loss, preventing a decrease in the heating level of the mixture by the first and second steam nozzles. Furthermore, the heated sintering mixture trough is located on the side closer to the ignition furnace, allowing the heated mixture to be immediately distributed on the sintering trolley and ignited in the furnace, reducing heat loss during transportation and thus improving the sintering mixing efficiency. The temperature of the material is maintained at a high level, improving the permeability of the material layer and increasing the thickness of the sintering layer, thus significantly increasing the yield and quality of sintered ore. Through this design, insulation cotton and insulation pipes are used to protect the material and prevent the loss of steam temperature in the steam pipes. The heated sintering mixture bin is placed on the side closer to the ignition furnace, so that the heated mixture can be immediately put into the ignition furnace for ignition, reducing heat loss during transportation, improving the permeability of the material layer, increasing the thickness of the sintering layer, and thus significantly increasing the yield and quality of sintered ore.
[0018] 2. In this utility model, by providing a first steam nozzle and a second steam nozzle, when the mixture is heated by the first steam nozzle and the second steam nozzle, the positions of the first steam nozzle and the second steam nozzle are staggered, so that the sprayed steam can be evenly distributed in the mixture, which provides a guarantee for the stable operation of the entire steam preheating and the improvement of sintering. Through this design, by staggering the positions of the first steam nozzle and the second steam nozzle, the sprayed steam can be evenly distributed in the mixture, making the steam preheating operation more stable and further improving the air permeability of the mixture layer.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4 This utility model provides a technical solution: a novel steam preheating device for sintered mixed material ore bins, including a boiler steam drum 1, with an insulation pipe 2 installed at the top of the boiler steam drum 1, and a high-efficiency steam-water separator 3 installed at one end of the insulation pipe 2.
[0027] The high-efficiency steam-water separator 3 is equipped with a control valve 8, and a support frame 11 is provided at the bottom of the high-efficiency steam-water separator 3. A flow detector 9 is provided at one end of the control valve 8, and a pressure detector 10 is provided at one end of the flow detector 9. A gas transmission pipe 7 is provided in the pressure detector 10. A steam pipe is provided inside the insulation pipe 2. A sintering mixture ore trough 5 is fixedly connected in the gas transmission pipe 7. A sintering trolley 4 is provided at the bottom of the sintering mixture ore trough 5, and an ignition furnace 6 is provided at the top of the sintering trolley 4.
[0028] The specific implementation method is as follows: Insulation cotton is installed in the insulation pipe 2, and the steam pipe is located in the insulation cotton. When the insulation pipe 2 is in use, it can be protected by the insulation cotton and the insulation pipe 2 to avoid the loss of steam temperature in the steam pipe, which would reduce the heating level of the mixture by the first steam nozzle 14 and the second steam nozzle 15. The heated sintering mixture trough 5 is set on the side closer to the ignition furnace 6, so that the mixture is immediately distributed on the sintering trolley 4 after heating and enters the ignition furnace 6 for ignition. This reduces the heat loss during the transportation process, thereby increasing the temperature of the sintering mixture and keeping the temperature of the mixture at a high level. It also improves the permeability of the material layer, increases the thickness of the sintering material layer, and greatly improves the output and quality of sintered ore.
[0029] A connecting pipe 12 is fixedly connected to one side of the gas transmission pipe 7. One end of the connecting pipe 12 passes through the side wall of the sintering mixture ore trough 5. A gas storage shell 13 is fixedly connected to one end of the connecting pipe 12. A first steam nozzle 14 is fixedly connected to one side of the gas storage shell 13. A second steam nozzle 15 is fixedly connected to one side of the gas storage shell 13.
[0030] The specific implementation method is as follows: When the mixture is heated by the first steam nozzle 14 and the second steam nozzle 15, the steam can be evenly distributed in the mixture because the positions of the first steam nozzle 14 and the second steam nozzle 15 are staggered, which ensures the stable operation of the entire steam preheating and the improvement of sintering, and further improves the air permeability of the mixture layer.
[0031] Working principle: Insulation cotton is installed in the insulation pipe 2, and the steam pipe is located in the insulation cotton. When in use, the insulation pipe 2 is protected by the insulation cotton and the insulation pipe 2 to avoid the loss of steam temperature in the steam pipe, which would reduce the heating level of the mixture by the first steam nozzle 14 and the second steam nozzle 15. The heated sintering mixture trough 5 is set on the side closer to the ignition furnace 6, so that the mixture is immediately distributed on the sintering trolley 4 after heating and enters the ignition furnace 6 for ignition, reducing heat loss during the transportation process. This increases the temperature of the sintering mixture, keeps the temperature of the mixture at a high level, improves the permeability of the material layer, increases the thickness of the sintering material layer, and greatly improves the output and quality of sintered ore. When the mixture is heated by the first steam nozzle 14 and the second steam nozzle 15, the staggered position of the first steam nozzle 14 and the second steam nozzle 15 allows the sprayed steam to be evenly distributed in the mixture, which ensures the stable operation of the entire steam preheating and the improvement of sintering, and further improves the permeability of the mixture layer.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
