Description
Technical field
The present invention and a kind of solar energy hot water tank, belong to technical field of solar utilization technique.
Background technology
The places such as vast rural area, pastoral area, building site, school, time at nightfall Personal hygiene have a bath, foot bath cold water to be heated extremely
45-55 DEG C could use, and needs the fuel such as combustion gas, firewood, and cost is time-consuming, not environmentally etc..
Summary of the invention
For certainly the problems referred to above, the present invention provides a kind of solar energy hot water tank.
For the most above-mentioned technical problem, the present invention provides a kind of solar energy hot water tank, by wooden water tank, dark colour glass,
Scantling in stainless steel band, water tank, little batten, water container backwater pipe, water supply tank, upper overflow pipe, lower overflow pipe, hot-water line, from the beginning
Water pipe, electromagnetism priming valve, hot cool tone joint valve, shower nozzle, tank bracket, Drag link, intermediate supports, water level sensor, triangle
Support composition, it is characterized in that: described solar water box material uses Chinese fir board to make, and Chinese fir board thickness is 30-40mm.
Owing to Chinese fir board has good heat-insulating property, dress water after heat cold deformation is little, is a kind of well solar water
Box material.
The upper limb of wooden water tank and lower edge stainless steel band hoop-driving, on steel band, 100-200 mm length bores a hole, with wood
Screw is reinforced.
The inside and outside of wooden water tank is all coated with 2-3 time with varnish, during japanning, repastes second time after the paint of first pass is absolutely dry, the
The 3rd time is repasted after doing for two times.
The above covering dark colour glass of wooden water tank, thickness of glass is 10-12mm.
Wooden water tank the most reserved interior 13 mm width suitable for reading, scantling in water tank, scantling specification in water tank are installed in lower section
For 20mmX20mm, in water tank, on scantling, it is coated with one layer of nail-free glue or glass cement, dark colour glass is placed on reserved case mouth
In, more solid with nail-free glue or glass cement, glass edge compresses with little batten and wood screw after topcoating glass cement, it is impossible to leak.
Tank bracket flitch or rustless steel square tube process, and the lower limb at two ends all uses the splayed triangle noted in figure
Support.
The drift angle of splayed gusseted requires to be 90-100 degree, and the legs and feet Drag link at two ends is fixed, the centre on both sides
Respectively add an intermediate supports.
Tank bracket is placed on roof or on flat roof, and wooden water tank requires to set level, just to sunlight, it is impossible to have tree
Branch and the building shield sunlight of high level.
Wooden water tank is upwards provided with water container backwater pipe, is connected with water supply tank, and water supply tank requires to exceed wooden water tank.
Water supply tank is arranged over overflow pipe and lower overflow pipe, prevents water unnecessary when adding water from overflowing.
Water supply tank is arranged over water level sensor.
Hot-water line upper end connects with wooden water tank, and lower end connects with the hot-water line of hot cool tone joint valve.
The cold water pipe of hot cool tone joint valve connects with running water pipe.

Electromagnetism priming valve carries out on an off.
When in wooden water tank, water is filled it up with, water level sensor controls electromagnetism priming valve and closes.
When in wooden water tank, hot water is finished, water level sensor controls electromagnetism priming valve and opens, by the pressure warp of tap water
The electromagnetism priming valve opened send water to hot-water line and injects in wooden water tank.
Three times of the width degree of being of wooden water tank, length is pressed necessary volume and is calculated；The family of general six mouthfuls recommends
0.2-0.3m3(wide 800 mm length 1200 mm volume 0.24 m of high 250 mm3).
Hot cool tone joint valve can two-way switch, and can two-ways regulation flow, heat can be turned down when the water outlet of shower nozzle is overheated
Water strengthens cold water flow, otherwise then strengthens hot water flow, turns down cold water flow, makes lower water temperature arrive suitable temperature.
The solar energy hot water tank of present invention design, has following progress.
Under identical time and the same terms, its temperature is to be exceeded more than 10-20 DEG C than the basin plowed open.
Particularly standing time at night, its temperature difference the longest was the biggest, and intuitively, the heat of solar energy hot water tank
Water very sanitation and hygiene, and the hot water of the basin plowed open has on foreign material bubble through the water column, the most unhygienic.
Dark colour glass has a strongest absorbing ability, and the luminous energy of refraction is transformed into thermal energy conduction to cold water, makes cold water
The very long rising of temperature.
Owing to solar energy hot water tank has stronger heat-insulating property, so water temperature is rising to rear water temperature identical with outdoor temperature
Also may proceed to rise, after 10 hours, water temperature may be up to more than 70-80 DEG C.
Solar energy hot water tank design is simple, it is easy to making, cost is extremely low, and durable in use.
Summer through one day sunlight heat, water temperature reaches as high as 90 degree；The water temperature in winter having the sun is also not less than 50
Degree.
In sum, the solar energy hot water tank of present invention design, there iing the local use of sunlight, efficiently solving family
Bathing, wash dish, do washing, the domestic such as cook；Can be family, entity and individual be time-consuming, cut down expenses, save fuel, minimizing
Discharge, environmental, promote the well-being of mankind, benefit the nation, favorable to the people, sharp.
Its manufacture method is simple and convenient, is especially suitable for the local use such as wide farmers, herdsman, building site, school.
