Abstract
The utility model relates to a combined energy saving purifying low noise hot air curtain, mainly composed of a blower fan, a heater, a motor and an air outlet. The utility model is characterized in that the heater is installed on the negative pressure zone of the inlet of the blower fan and adopts the suction type heat change. An air inlet is provided with a filter with coarse effect, and the inner part of the utility model is provided with a micropore muffler plate and ultramicro glass wool cotton or muffling flame resistance polyester foam. The hot air curtain of the utility model has the advantages of compact structure, small volume, power saving, energy saving, mounted occupation area saving and convenient maintenance and transportation, and can be used in a unit mode and also be used in a combined mode. The utility model can blow from the top and also blow from the side.
Description
The utility model relates to a kind of entrance hall heating heat-preserving equipment one combined energy-saving and purifies the low noise warm air curtain.
In recent years,, generally all use warm air curtain to replace the cotton-wadded quilt door curtain, can be the indoor heating insulation necessary assurance is provided, avoid indoor thermal loss in the door district winter heating insulation that often has personnel and vehicle frequently to pass through.But to exist volume mostly big for the warm air curtain of some manufacturer production at present, thereby need take enough spaces when installing; Have the big and not high deficiency of the thermal efficiency of noise in addition; After the old-fashioned warm air curtain long-term operation, heater blocks easily, and air quantity and heat dissipation capacity are reduced; For 4 meters high sealing up a door to the doorstep, need a large amount of heats and electric energy and heating facility, thus exist be difficult to satisfy that heat requirement, occupation area of equipment are big, problems such as installation and inconvenient maintenance.
The purpose of this utility model provides a kind of combined energy-saving and purifies the low noise warm air curtain.
The purpose of this utility model is achieved in that
Air inlet place at warm air curtain is equipped with low efficient filter, prevents that effectively the dust foreign material from entering heater, can improve the efficient of heater in the long-term operation.Portion's body plan within it has micro silencer plate and ultra micro glass silk flosssilk wadding or noise elimination fire-retardant polyester foamed plastics, adopts silent ventilator, motor in addition, and it is effective that complete machine is eliminated the noise, thereby noise is low.Adopt copper pipe string aluminium flake secondary flange heater.And the air heater heat exchange is a suction-type, can improve heater heat exchange efficiency 15%.This novel warm air curtain compact conformation, volume are little, can use the unit, also can be used in combination, but top blast also can blow side, save the equal floor space of installing greatly, keep in repair and transport all very convenient simultaneously.When particularly using as the side-blown warm air curtain, door is high to use heater below two meters, can guarantee that the pedestrian passes through comfort.And seal up a door without heater in space more than two meters, than the energy-conservation 30-60% of old product, along with door highly increases, energy-saving effect is better.
Describe its technical solution in detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 purifies the structural representation of low noise warm air curtain for combined energy-saving.
Fig. 2 purifies the outline drawing of low noise warm air curtain for combined energy-saving
Fig. 3 purifies the scheme of installation of low noise warm air curtain for combined energy-saving.
Referring to Fig. 1 and 2, the shell of warm air curtain is made of upper cover plate 13, air-supply base plate 5 and back shroud 8, and its heater 2 is installed in the negative pressuren zone of fans entrance by heater stand 4, adopts the suction-type heat exchange.Air inlet place at warm air curtain, low efficient filter 1 is installed, portion is equipped with micro silencer plate and ultra micro glass silk flosssilk wadding or noise elimination fire-retardant polyester foamed plastics 15 within it, heater installing rack 4 is fixed on the housing, and in housing, form air hybrid chamber 14, motor 9 and blower fan 10 are fixed on the mounting bracket 11, and 3 is discharging valve; 6 is air outlet; 7 is guide vane; 12 is suspension bracket; 16 is side plate.
Air by air inlet enters by filter 1 after heater 2 heating, is blown out by air outlet 6 by fan outlet.Two kinds of mounting means such as Fig. 3.
Embodiment: adopt many Jis of novel microporous noise elimination forward direction aluminium alloy impeller, low noise F class B insulation external rotor electric machine, import low noise double sealed bearing, blower fan that efficient damper is housed, air quantity is big, pressure head is high, and the actual measurement noise is lower than like product 10-15 decibel.Power of motor is little, efficient is high, little power consumption.Machine energy-saving is respond well, and for example: adopt the side-blown mode, 3 meters high door is saved heat energy 30%; 4 meters high door is saved heat energy 50%; 6 meters high door can save energy 60%; 8 meters high door is energy-conservation 80%, no space on the door, and the air door form that blows side is not subjected to a high restriction, can seal the arbitrary height gate.The volume ratio old product is little nearly 1/2, saves floor space is installed.And can select the explosion-proof type blower fan for use according to user's needs, and high efficiency particulate air filter is made into the warm air curtain of explosion-proof type warm air curtain and air purification type, and the dimensions model can be optional according to the size of door.
