Technical Field

The utility model relates to a steam production technical field, in particular to agitator at angle of inclination is transferred to buoyancy for steam generator.

Background

In the prior art, the vertically arranged hot air steam generator is basically formed by heating water in a water storage tank by an electric heater or fuel oil combustion to generate heat to be evaporated to form steam. In order to realize the full utilization of solar energy, the solar energy is used for heating air, then the hot air is input into a heat exchanger in a water storage tank through a pipeline, when the hot air passes through the heat exchanger, the heat is conducted to water in the water storage tank so that the water is evaporated to form steam, the air releasing the heat flows back to a solar heater to be heated by the solar energy, and the circulation is carried out. Since hot air is heated in a flowing manner, heat still flows away if the heat is not exchanged in time (while the traditional electric heating and fuel oil heating is that a heat source is always maintained in a water storage rod tank (namely static heating), the heat exchange efficiency is high and low, the heat is finally released into water, the heat exchange efficiency is affected only by a long heating time end and cannot cause excessive increase of heat loss), the heat flowing away along with the hot air is equivalent to heat loss, and the existing steam generator is heated in a static state, so that water is kept still in the heating process (because the static heating does not need water to move), and the heat exchange speed between the heat exchanger and the water is slow. For this reason, a stirrer is added in the steam generator for stirring, but the force for pushing the liquid to rise when the existing stirrer stirs is fixed (or only changes along with the change of the rotating speed) and cannot change along with the change of the liquid level, but the force for pushing the water up is larger when the liquid level depth is increased.

SUMMERY OF THE UTILITY MODEL

The utility model provides a go up the agitator that pushes up the buoyancy that the power of water can increase along with the increase of water level transfers the angle of inclination for steam generator, solved the problem that the power of current agitator push up water can not change along with the change of liquid level.
