Abstract
An automatic air interchanger with wind power solves the defects of large investment and high energy consumption existing in the present air blowers, fan and other electric drive equipment used for indoor ventilation, deodorization and air change. The air interchanger comprises a Venturi double-horn, an exhaust duct is inserted in the middle, where the caliber is smallest, of the Venturi double-horn from down to up, the lower part of the exhaust duct is closed, and a port at the lower part of the exhaust duct is an air outlet. In the Venturi double-horn, the left and right sides of the exhaust duct are provided with a left hole and a right hole, and the left hole and the right hole on the exhaust duct are provided with an automatic reversing valve. Only by using natural wind, the air interchanger can achieve the aim of automatic air change or deodorization for pump rooms, analysis rooms, rest rooms, kitchens and other indoor spaces, and is simple in structure, long in service life, little in investment and low in energy consumption.
Description
Technical field
The utility model relates to indoor exhaust wind, taste removal, air interchanger, particularly a kind of automatic air interchanger of wind-force that is applied in indoor automatic ventilations such as pump house, analysis room, toilet, kitchen or taste removal.
Background technology
Indoor exhaust wind, taste removal, air interchanger mainly contain driven by power equipment such as blower fan, fan at present, have the shortcoming that investment is big, energy consumption is high.
The utility model content
The technical problem that will solve of the present utility model provides a kind of automatic air interchanger of wind-force that utilizes natural wind, to reach the purpose of indoor automatic ventilations such as pump house, analysis room, toilet, kitchen or taste removal.
The utility model is to form like this: it comprises venturi double horn tube, the thinnest bore place is fitted with exhaust duct from the bottom to top at venturi double horn tube middle part, the sealing of exhaust duct top, lower port are exhaust outlet, be positioned at venturi double horn tube and arranged on left and right sides at exhaust duct and be provided with left and right hole, place, left and right hole is equipped with automatic diverter valve on exhaust duct.
The automatic air interchanger of above-mentioned wind-force, described automatic diverter valve are by the connecting plate that is installed in place, left and right hole, are installed in the left and right windscreen sheet at connecting plate two ends, and wherein the connecting plate middle part is positioned at exhaust duct, and left and right windscreen sheet is positioned at outside the exhaust duct.
The automatic air interchanger of above-mentioned wind-force, corresponding connecting plate position is provided with roller or roller bearing in exhaust duct, and described connecting plate is positioned on roller or the roller bearing.
The utility model utilization enters venturi double horn tube from a side natural wind increases to the minimum kinetic energy of diameter, and potential energy reduces, and produces negative pressure; Simultaneously the windscreen sheet of windward side automatic diverter valve is stressed, and automatic diverter valve moves with the wind, with the perforate of windward side exhaust duct block, the opposite side perforate opens, the gas in the exhaust duct bottom compartment is discharged along the hole of opening under the effect of its top negative pressure.Like this, because the cooperation of automatic diverter valve is arranged, no matter natural wind from which direction blows, can both produce negative pressure, stop wind-fall to be irritated simultaneously, realize automatic air-exhausting function, thereby reach the purpose of indoor automatic ventilation such as pump house, analysis room, toilet, kitchen or taste removal, and simple in structure, long service life, energy consumption is low, investment is little.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the I portion enlarged drawing of Fig. 2.
Among the figure: venturi double horn tube 1, exhaust duct 2, right windscreen sheet 3, connecting plate 4, left windscreen sheet 5, roller 6, support 7.
The specific embodiment
As shown in Figure 1, the utility model has a venturi double horn tube 1, the thinnest bore place is fitted with exhaust duct 2 from the bottom to top at venturi double horn tube 1 middle part, the sealing of exhaust duct 2 tops, lower port are exhaust outlet, be positioned at venturi double horn tube 1 and arranged on left and right sides at exhaust duct 2 and be provided with left and right hole, place, left and right hole is equipped with automatic diverter valve on exhaust duct 2.Described automatic diverter valve is to be made of connecting plate 4 and the left and right windscreen sheet 5,3 that is fixed on connecting plate 4 two ends, connecting plate 4 middle parts are positioned at exhaust duct 2, it is outer and the exhaust duct perforate of wind-engaging side can be blocked when being positioned at the windscreen sheet wind-engaging of a side that left and right windscreen sheet 5,3 is positioned at exhaust duct 2, corresponding connecting plate 4 positions are provided with support 7 in exhaust duct 2, roller or roller bearing are installed on support 7, present embodiment is an example so that roller 6 to be installed, and described connecting plate 4 is positioned on the roller 6.
During installation, exhaust duct 2 bottoms deeply need the room of air draft, and natural wind enters venturi double horn tube 1 from a side, increase to the minimum place of diameter kinetic energy, and potential energy reduces, and produces negative pressure.Windward side windscreen sheet is stressed simultaneously, and automatic diverter valve moves with the wind, and the perforate of windward side exhaust duct is blocked, and the opposite side perforate is opened, and the gas in exhaust duct 2 bottom compartment is discharged along the hole of opening under the effect of its top negative pressure.On the contrary, natural wind enters venturi double horn tube 1 from opposite side, increases to the minimum place of diameter kinetic energy, and potential energy reduces, and produces negative pressure.Windward side automatic diverter valve windscreen sheet is stressed simultaneously, and automatic diverter valve moves with the wind, and the perforate of windward side exhaust duct is blocked, and the opposite side perforate is opened, and the gas in exhaust duct 2 bottom compartment is discharged along the hole of opening under the effect of its top negative pressure.Like this, because the cooperation of automatic diverter valve is arranged, no matter natural wind from which direction blows, and can both produce negative pressure, stops wind-fall to be irritated simultaneously, realizes automatic air-exhausting function.
Claims (3)
