Description

Technical Field

[0001] This utility model relates to the field of water tank heating technology, and in particular to an automatic mixing heating water tank. Background Technology

[0002] The water added to the mixer is taken from the circulating water tank of the wet electrostatic precipitator. According to the sintering process requirements, the water added to the mixer needs to meet the requirement of 90°C or higher. However, the water temperature in the circulating water tank does not meet the technical requirements. In order to ensure that the sintering process requirements are met, the water in the circulating water tank needs to be heated to 90°C through a heating water tank.

[0003] However, since the mixer needs a continuous supply of water, the water in the tank is constantly being drawn out. Water closer to the heating point of the tank heats up faster, while water farther away heats up slower, resulting in a certain temperature difference in different areas of the tank. A large temperature difference will cause large fluctuations in the temperature of the mixture, which will seriously affect the stability of sintering production.

[0004] Therefore, a heating water tank that can ensure uniform heating of water in all areas of the tank is needed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing an automatic mixing heating water tank. The water flow is heated by steam transmitted through a steam channel, and the water flow drives a propeller to rotate and agitate the water flow, thereby uniformly mixing the water in different areas and reducing the temperature difference between the water in each area. This helps to avoid excessive temperature differences in the mixed material later, which could lead to instability in the sintering production.

[0006] This utility model is achieved through the following technical solution: It provides an automatically mixing heating water tank, including a tank body with an inlet and an outlet at each end; a steam pipe is installed inside the tank; a propeller is mounted on the steam pipe, positioned between the inlet and outlet; the propeller includes a hub fitted onto the steam pipe and blades arranged around the hub; an air inlet chamber and an air outlet chamber extending circumferentially from the inner side of the hub are provided; steam channels connecting the air inlet and outlet chambers are provided on the blades; a baffle is installed inside the steam pipe, with an air inlet hole connecting the air inlet chamber and an air outlet hole connecting the air outlet chamber on both sides of the baffle; steam is transmitted within the steam channels and heats the water flow; the water flow drives the propeller to rotate; the propeller agitates the water flow and heats different areas within the tank, simultaneously mixing the water in different areas and reducing the temperature difference between areas, thereby preventing excessive temperature differences in the mixed material later, which could lead to unstable sintering production.

[0007] As an optimization, the blades are provided with several crisscrossing steam channels that are interconnected; this increases the contact area between the steam and the blades, thereby accelerating the heat exchange between the steam and the water flow.

[0008] As an optimization, through holes are provided on the blades, which are located between the steam channels; the through holes disperse the water flow and increase the mixing effect of the water flow in each area.

[0009] As an optimization, the propellers are arranged sequentially along the steam pipe axis; by having the propellers arranged sequentially along the steam pipe axis to agitate the water flow multiple times, the mixing effect of the water flow is increased.

[0010] As an optimization, adjacent propellers rotate in opposite directions; by using propellers with opposite rotation directions, the water flow crosses and mixes, increasing the mixing effect of the water flow.

[0011] The beneficial effects of this utility model are as follows: the steam transmitted in the steam channel heats the water flow, and the water flow drives the propeller to rotate. The propeller stirs the water flow and heats different areas in the water tank. At the same time, the water in different areas is evenly mixed and the temperature difference between the water in each area is reduced, thereby avoiding the instability of sintering production caused by excessive temperature difference of the mixed material in the later stage.

The air inlet 3011 and the air outlet 3012 are respectively connected to the air inlet 3011 and the air outlet 3012. The steam pipe 2 is provided with a baffle 201. The steam pipe 2 on both sides of the baffle 201 is respectively provided with an air inlet 202 connecting the air inlet 3011 and an air outlet 203 connecting the air outlet 3012. The steam pipe 2 is made of heat-conducting material. The water inlet 101 and the air inlet of the steam pipe 2 are located at both ends of the box 1, and the water flow direction and the steam flow direction are opposite.

[0015] Steam is transmitted in steam pipe 2, and enters air intake chamber 3011 through air inlet 202. Steam in air intake chamber 3011 is transmitted to air outlet chamber 3012 through steam channel and flows to steam pipe 2 on the other side of partition 201 through air outlet 203. At the same time, steam heats water flow through blades 302. Water flow in tank 1 drives propeller 3 to rotate on steam pipe 2. Blade 302 agitates water flow and heats different areas in water tank. At the same time, water in different areas of water tank is evenly mixed, and the temperature difference between water in each area is reduced.

[0016] like Figure 4 The blade 302 shown has several crisscrossing steam channels that are interconnected; the blade 302 is composed of crisscrossing and interconnected air guide pipes, and the steam channels are located inside the air guide pipes.

[0017] like Figure 4 The blade 302 shown has a through hole located between the steam channels; the gap between the air guide pipes forms the through hole.

[0018] like Figures 1-3 The propellers 3 shown are arranged sequentially along the axial direction of the steam pipe 2.

[0019] Propeller 3 rotates sequentially, mixing the water in different areas of the water tank multiple times.

[0020] like Figures 1-3 The adjacent propellers 3 shown have opposite rotation directions.

[0021] Adjacent propellers rotate in opposite directions, causing water from different areas of the tank to mix crosswise.

[0022] In actual use, steam is transmitted in steam pipe 2, and steam enters air intake chamber 3011 through air inlet 202. Steam in air intake chamber 3011 is transmitted to air outlet chamber 3012 through steam channel and flows to steam pipe 2 on the other side of partition 201 through air outlet 203. At the same time, steam heats water flow through blades 302. Water flow in tank 1 and drives propeller 3 to rotate on steam pipe 2. Blades 302 agitate water flow and heat different areas in water tank. At the same time, water in different areas of water tank is evenly mixed, and the temperature difference between water in each area is reduced.
