Abstract
A greenhouse gutter snow melting system comprises a heating device, snow melting tubes and a heat exchanger, the heat exchanger is respectively communicated with the heating device and the snow melting tubes so as to form a heating loop and a snow melting loop which are mutually independent, one group of snow melting tubes are arranged in a gutter at the top end of a greenhouse framework, the snow melting tubes are parallelly distributed above the gutter, and circulating passages are formed among the snow melting tubes. The greenhouse gutter snow melting system utilizes a boiler as a heat source, is provided with the heating loop and the snow melting loop which are mutually independent, multiple groups of snow melting tube loops in the snow melting loop are in one-to-one correspondence to the gutter on the outer side of an greenhouse, and the snow melting tubes directly contact with accumulated ice. After the heat exchanger is used for exchanging heat and a booster pump of the snow melting loop is used for boosting pressure, the greenhouse gutter snow melting system is fast in loop circulation, high in heat exchange efficiency and rapid in snow melting, avoids freezing off pipelines as the snow melting loop adopts antifreeze liquor as a heated medium, and is high in operating stability.

Background technology
The greenhouse end face generally adopts civilian network roof construction at present, and wherein, gutter is installed in the Keelof green house top as end face load parts, and gutter forms rhone, bears the function of getting rid of top, chamber sleet water.After snowing winter, accumulated snow is deposited in roofing and gutter place, after accumulated snow partly melts, is difficult for discharging, and the place causes accumulated ice at gutter, and accumulated ice is piled up to be increased, and can extend to both sides roofing is covered, and increases shaded area, reduces light transmittance; Simultaneously, long-term accumulated ice has also increased the heat energy loss of greenhouse system.And because gutter is the strip supporter, and the roofing overlay load-bearing at gutter two ends is limited, is very easily decreased by the long-pending weight of ice slush.
The utility model content
The utility model be used to overcome prior art defective, the greenhouse gutter snow melting system that a kind of snow melt is effective, help saving energy and reduce the cost is provided.
The purpose of this utility model realizes with following technical scheme:
A kind of greenhouse gutter snow melting system, be provided with heater, snow melt pipe and heat exchanger in the formation, it is separate heating circuit and snow melt loop that described heat exchanger is communicated with heater and snow melt pipe respectively, wherein, be provided with one group of snow melt pipe in the gutter on Keelof green house top, the parallel gutter top that is laid in of snow melt pipe forms the peripheral passage between the described snow melt pipe.
Above-mentioned greenhouse gutter snow melting system is provided with independently heat tunnel and heated passage at least in the described heat exchanger, described heat tunnel is communicated with water inlet pipe, the return pipe of heater respectively and forms heating circuit; Heated passage is communicated with formation snow melt loop respectively by its import, outlet with the snow melt pipe.
Above-mentioned greenhouse gutter snow melting system, described snow melt loop is provided with main line, and main line is corresponding with the gutter height, and described main line comprises heating tube and return duct, and the parallel snow melt pipe that is laid in the gutter is communicated with heating tube and return duct respectively.
Above-mentioned greenhouse gutter snow melting system, the heated passage of described heat exchanger is a thermal-collecting tube, thermal-collecting tube import department is provided with force (forcing) pump.
Above-mentioned greenhouse gutter snow melting system, it is anti-icing fluid that the working medium in the described snow melt loop adds hot fluid.
The utlity model has following beneficial effect:
The utility model is laid the snow melt pipe in gutter, utilize the existing boiler in greenhouse as thermal source, and heating snow melt speed is fast, effective, guarantees in the gutter not accumulated snow accumulated ice, does not influence near the daylighting the gutter; Heat exchanger of the present utility model adopts separate heating and snow melt loop, good effect of heat exchange, and efficient energy-saving, the hot fluid that adds in the snow melt loop adopts anti-icing fluid, avoids outside temperature to cross low conduit failure, and is safe.
