Description

Stirring paddle with buoyancy inclination angle adjusted for steam generator

Technical Field

The utility model relates to a steam production technical field, in particular to stirring rake 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

And current stirring rake rotates the power of in-process push-up water and is for keeping unchangeable, so the speed that water rises when the depth of water can slow, then the speed that the water that means with the heat exchanger contact carries out the transform is slow, the transform speed then means that heat transfer speed is slow slowly, so can lead to the depth of water to be big to the influence of heat transfer when current stirring rake is used for steam generator's stirring, and the utility model provides a dip angle of push pedal can increase when the agitator depth of water increases to the power increase of push-up water when having realized the depth of water increase, thereby can reduce the influence of the depth of water increase to heat transfer speed. In the designed water level range, when the water level is lowered to cause the inhaul cable to be loosened, the supporting rod is contracted under the action of the spring to drive liquid in the horizontal smooth pipe to enter the hydraulic cavity and drive the piston of the connecting pipe part to be far away from the vertical rotating shaft, so that the inhaul cable is kept in a tensioning state. The action point of the thrust generated by pushing the push plate by water in the rotating process is always positioned below the shaft pin.

The utility model also comprises a fixed pulley, a guy cable via hole is arranged in the horizontal connecting rod, the guy cable via hole is separated from the horizontal sliding cavity by a separation plate, the guy cable extends out of the hydraulic cavity through the separation plate and the guy cable via hole and then is supported on the fixed pulley for reversing and is connected with the floating ball of the stirrer part, and the guy cable is connected with the separation plate in a sealing and sliding way; when the inhaul cable is tensioned, the inhaul cable is disconnected with the hole wall of the inhaul cable through hole. The resistance when the cable removes can be reduced to the realization makes again can drive when the floater is less.

Preferably, the shaft pin is parallel to the horizontal slide tube. The smoothness is better when the supporting rod drives the push plate to rotate.

Preferably, when the supporting rod extends out of the horizontal sliding pipe to the limit position, the inclination angle of the push plate is 45 degrees, and when the supporting rod is inserted into the horizontal sliding pipe to the limit position, the push plate is in a vertical state.
