Description

Technical Field

[0001] The utility model relates to a water tank, in particular to a constant-temperature heating water tank for sintering mixed materials. Background Art

[0002] During the sintering production process, water needs to be added to the mixing drum to ensure the nucleation and pelletizing of the mixture. Adding hot water can better make the quicklime in the mixture react and release heat, and can also increase the temperature of the mixture, reduce fuel consumption in the sintering production process, and improve the quality of sintered ore.

[0003] The mixed heating water pool adopts an open-air heating water pool, which will cause waste of steam. The steam may easily cause burns to people around during the dissipation process. The reduction of heating points in the open-air heating water pool will cause a large difference in water temperature in different areas of the pool, resulting in large temperature fluctuations of the mixture and affecting the stability of sintering production.

[0015] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0016] according to Figure 1 As shown, a constant temperature heating water tank for sintering mixture includes a tank body 3 and a high-temperature steam pipe 8. The tank body 3 is connected to a water inlet pipe 7 for injecting cold water. The high-temperature steam pipe 8 is connected to the tank body 3 and extends into the tank body 3 to be connected to the outlet part 10 so as to inject high-temperature steam into the outlet part 10. The outlet part 10 is provided with an air jet hole 2 facing the bottom surface of the tank body 3. The high-temperature steam ejected from the air jet hole 2 heats the cold water injected into the tank body 3. The top of the tank body 3 is provided with an exhaust pipe 5 for exhaust and the side is connected to a water outlet pipe 1 for outputting hot water.

[0017] In this embodiment, a bellows 6 for conveying high-temperature steam is provided between the outlet portion 10 and the high-temperature steam pipe 8. The metal structure of the bellows 6 is beneficial to extending the service life of the pipeline. The high-temperature steam ejected from the jet hole 2 causes the outlet portion 10 to vibrate axially and radially, and the bellows 6 plays a role in buffering and reducing vibration.

[0018] In this embodiment, in order to ensure a continuous supply of hot water, two water outlet pipes 1 are connected to the side of the box body 3, and the water outlet pipes 1 are respectively connected to the centrifugal pumps, and then the hot water is pumped out through the centrifugal pumps. At the same time, one centrifugal pump is used and the other is spare to avoid interruption of the hot water supply due to failure of the centrifugal pump.

[0019] In this embodiment, a water level gauge 4 for detecting the water level is provided in the box body 3. The water level gauge 4 detects the liquid level of hot water in the box body 3. When the liquid level is lower than the set liquid level, the amount of water injected into the box body 3 is increased through the outlet pipe 1. The water level gauge 4 is preferably a float type water level gauge or a pressure type water level gauge.

[0020] In this embodiment, the outlet portion 10 adopts an H-shaped structure or a spiral structure. Since the high-temperature steam ejected from the jet hole 2 will cause the outlet portion 10 to generate a reaction force and vibration, the outlet portion 10 adopting this structure has better stability.

[0021] In this embodiment, an overflow hole 9 is provided on the box body 3. When the liquid in the box body 3 reaches a certain height, it flows out through the overflow hole 9, thereby avoiding danger and loss caused by container rupture or overflow due to overfilling.

[0022] Working principle: First, the water inlet pipe 7 continuously injects cold water into the box 3. At the same time, high-temperature steam is transported into the outlet part 10 through the high-temperature steam pipe 8. The high-temperature steam is ejected through the jet hole 2 on the outlet part 10. The steam releases a large amount of heat. The steam is in direct contact with the cold water. There is almost no thermal resistance in the heat transfer, and a thermal efficiency close to 100% can be achieved. This method will make the water boil, the mixing effect is better, and the consistency of the hot water temperature is ensured. The generated hot water is output through the water outlet pipe 1.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
