Description

Novel warm-air machine

Technical field: the utility model relates to the HVAC firing equipment, is meant a kind of novel warm-air machine of the usefulness that mainly is suitable for heating in the plant husbandry hot house canopy in winter.

Background technology: the northern area of China plant husbandry hot house, particularly plastic vegetable greenhouse, winter, the canopy domestic demand was heated, before the utility model, the common coal-fired chimney stoves that adopt of heating in the canopy more, a booth often need be given birth to several stoves, defectives such as existence heats up slow, and temperature is unbalanced, and smoke pollution is big; Have and adopt miniature boiler to heat, its investment is big, the expense height, and most peasant households hold and can't stand; Having the heating of a kind of family to use coal-fired warm air furnace, is to set up the cold wind heating jacket outside common coal furnace body of heater, generally circulates naturally by air and heats air-supply, and its efficiency of heating surface is low, and hot blast rate is little, is unsuitable for using in booth.

Summary of the invention: the goal of the invention of the utility model, be to remedy the deficiency of prior art, a kind of highly effective novel warm-air machine of the usefulness that mainly is suitable for heating in the green house of vegetables canopy in winter is provided.

The utility model is so implemented, and hot house is heated and use novel warm-air machine winter, and its structure comprises that coal-fired furnace, ring oven body add hot-flow flue and all parts of exhaust duct, and heating furnace (1) has the burner hearth that its cross section is arch; Many logical cores add that warm-air pipe (7) is vertical wears burner hearth, and its two ends are fixed on the forward and backward wallboard of burner hearth (5) and (3); Constitute front, rear, left and right between burner hearth front, rear, left and right wallboard and top arch bar and the shell body (26), reach air channel, top (10), (8), (11), (9) and (12); Induced-draught fan (2) is installed on housing back wall air inlet place, is communicated with air channel, back (8); Left side air channel madial wall (6), affixed housing inner roof wall on it, its down affixed burner hearth left side wallboard, left air channel one end is communicated with primary air separating duct (10), and the other end is housing back wall exhaust outlet (23); The exhaust duct of external exhaust outlet (24) but the more piece socket, endcapped, tube wall are distributed with air draft aperture (25).

A kind of preferred version of this novel warm-air machine is mounting heat exchanger in left air channel (17), the vertical burner hearth of wearing of upper hose (18).

Good effect of the present utility model is, enter cold air in the housing by induced-draught fan, in burner hearth, add warm-air pipe and right air channel and air channel, top by the air channel, back and come together in primary air separating duct, discharge through left air channel exhaust outlet, cold wind is fully heated again, and heating is fast, the thermal efficiency is high, hot blast rate is big, canopy temperature is promoted rapidly, and temperature equalization, easy for operation, help plant growth; Mounting heat exchanger in left air channel has made full use of coal-fired heat again, and hot water is provided, and has increased function.
