Abstract

The utility model discloses a floating watering cycler for solar water heaters in the solar heat collection system. The structure of the floating watering cycler for solar water heaters is that two honeycomb ducts whose upper ends respectively provided with a water inlet and a water outlet can rise and fall along with the liquid level depending on the buoyant force of liquid are arranged from bottom to top in a hot water tank. One of the honeycomb ducts is a hot water supplying honeycomb duct, and the other is a cocycle honeycomb duct; the water inlet of the hot water supplying honeycomb duct is higher than the water outlet of the cocycle honeycomb duct; the lower ends of the two honeycomb ducts are respectively communicated with a hot water supplying duct and a cocycle duct. The floating watering cycler for solar water heaters has the advantages that the hot water of the whole hot water tank can be taken out, and simultaneously the hot water of the upper layer can be channeled and taken out; the cycle interruption is avoided; the system of the floating watering cycler for solar water heaters has high effective heat utilization.

Description

Floating watering cycler for solar water heater

The utility model is the boiler water intaking EGR in the solar thermal collection system.

At present, no matter be single household's solar energy system, or the solar energy in large area heating system all adopt natural circulation mode as far as possible, because of comparing to other endless form, this mode has lot of advantages.Natural Circulation is that the water that utilizes thermosiphon principle to make to be heated by solar radiant energy enters in the circulation storage heat energy water tank automatically, the water at low temperature that proportion is bigger is sunken to the water tank bottom and flows into circulation port under the heat collector, again being risen after the solar energy heating flows into boiler, and going round and beginning again finally makes the FCL hot water and the external world reach thermal balance.

Notification number is that the Chinese patent literature of CN2118952U proposes a kind of " solar water heater guiding device ", it is to install ball float in boiler additional, ball float fluctuates with the height of water level, mozzle is the center with hollow bolster, rotate along with rising and falling of ball float is not more than 90 ° of circumference that rise and fall, upper hot water of water tank is delivered to shower person through mozzle.This device makes to take out FCL hot water and take out upper strata hot water synchronously with water surface decline becomes possibility.Since thermal cycle advance that the hot water mouth of pipe (being the cocycle mouth of pipe) should be taken at water surface elevation in the water tank could realize higher system available heat utilization rate more than 2/3rds, and the cocycle mouth of pipe all is fixedly set in water tank upper in the prior art, therefore too fast if a variety of causes is taken hot water, it is too late to advance the additional cold water of cold water pipe, will make the cocycle mouth of pipe be higher than liquid level and connect with atmosphere, interrupt circulation, system's cisco unity malfunction.The somebody proposes a kind of what is called " two circulation " scheme recently, promptly establishes two circulation mouths of pipe in the boiler differing heights.Though this can relax above-mentioned contradiction to a certain extent, but reducing to certain altitude, the underwater still can make the most next cocycle mouth of pipe also be higher than liquid level, and when a top circulation mouth of pipe is in liquid level when following, two circulation mouths of pipe all advance hot water, have reduced the available heat utilization rate of system.

The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of can take out FCL hot water and descend to drawing synchronously with the water surface get upper strata hot water, can avoid cycle interruption again, and the solar thermal collection system boiler water intaking EGR that system's available heat utilization rate is improved as far as possible.

The utility model purpose is realized by following structure: be provided with two from bottom to top and lean on liquid buoyancy can make them bring the mozzle of the upper end of the mouth of a river or delivery port with liquid level one lifting in boiler, wherein one is heat supply water mozzle, another root is the cocycle mozzle, the water inlet of heat supply water mozzle is higher than the delivery port of cocycle mozzle, the lower end of two mozzles respectively with heat supply water pipe and upper circular tube UNICOM.

Two mozzles both can be by having made with the lightweight floating body material of liquid surface lifting by self buoyancy, also can be realized by the fastening one or more buoyancy aid in mozzle top on it with liquid surface lifting.The mozzle that is fastened with buoyancy aid both can be rubber tube, and gentle elastic tube such as plastic tube also can be the rigid pipe that is provided with moveable hinge between mozzle lower end and boiler bottom.For improving the thermal efficiency, mozzle is preferably made by the heatproof heat-insulating material.

The utility model is compared with prior art, and advantage is to accomplish " stepless circulation " (comparing with above-mentioned " two circulation "), has both avoided cycle interruption fully, and the system that can guarantee again has the higher effective heat utilization efficiency.

Figure of description is the structural representation of embodiment.

Embodiment: see accompanying drawing.Among the figure: 1 for mending cold water storage cistern; 2 for mending the ball-cock assembly in the cold water storage cistern; 3 for being fastened on the ball float on the mozzle, and quantity is 1, and diameter is 300mm; 4 for being arranged at the blast pipe on boiler 5 tops, and the boiler volume is 2.8m ³6 is the heat supply water mozzle of being made by the adiabatic rubber of heatproof, and internal diameter is 40mm; 7 are the heat supply water pipe; 8 is shower nozzle; 9 is upper circular tube; 10 is the cocycle mozzle of being made by the adiabatic rubber of heatproof, and internal diameter is 40mm; 11 is solar thermal collector, and area is 28m ²12 are following circulation pipe; 13 for mending cold water pipe.Permanent discrepancy in elevation h among the figure between heat supply water mozzle water inlet and the cocycle mozzle delivery port is 50-100mm.The bottom surface of boiler 5 apart from the distance from top of heat collector 11 for being not less than 100mm.This device uses (being under the secret situation) respond well through reality, reliable operation.The broken sky water temperature is 58 ℃, and sunny day can reach 70 ℃.
