Abstract

The utility model relates to a hot air curtain, belonging to a heating device. The inner cavity of a heater is provided with a smoke pipe and an inner partition board which are connected with a boiler to form integration. The utility model uses the residual heat of the fume eliminated by the boiler to heat the air which passes through the heater. The heated air forms the heat negative curtain by a hot air curtain divided box to prevent the outdoor cold air invading and the indoor hot air flowing out to achieve the purpose of heat preservation. The utility model can be installed by only modified based on pipe lines of the original boiler. The utility model has the advantages of energy saving and low noise.

Description

Hot air curtain

The utility model belongs to heating installation.

A kind of air warm air curtain is arranged at present, be by boiler, the warm air curtain branch mailbox, outer rotor centrifugal heat blower fan, air-introduced machine, pipeline, air heater, kuppe up and down, outlet housing and chimney constitute, air heater is to have the seamless steel pipe of fin to become by arranged outside, and it is the steam that utilizes boiler to produce, and adds the hot air heater ambient air, the reusable heat blower fan is blown into heated air indoor, form air-spray (warm air curtain), do not invaded with the cold air that sealing chamber is outer, indoor hot-air does not outflow, it with steam as medium, it is big to have area of dissipation, the characteristics that air-spray is stable, and the shortcoming of its existence is, need with coal or electric as thermal source, complex structure, huge, noise is big, wastes energy.

The purpose of this utility model is to provide a kind of air warm air curtain.

The purpose of this utility model is to realize like this, two ends at heater are provided with smoke box, the outlet flue of smoke box and boiler joins, another smoke box and smoke box shell, flue and hot-flow flue join successively, inner chamber at heater is provided with internal partition, one side and hot blast flue gas dividing plate join, both sides join with heater housing respectively up and down, cold wind import and hot-blast outlet are separately positioned on the both sides up and down of heater housing, and the cold wind entrance driveway 33 or 34 in enclosure wall communicates with cold air duct and block successively in the cold wind import.

Heater of the present utility model joins because of the outlet flue with boiler, its inner chamber is provided with many smoke pipes and an internal partition, it can be by the fume afterheat that is discharged from from boiler, enter air in the heater with heating, utilize air-heater to be blown into indoor by the warm air curtain branch mailbox heated air again, form warm air curtain, it is simple in structure, noise is low, energy savings, and the utility model only needs on original boiler tubing basis, repacking a little, just can install, it can be as the shop, school of office, service industry, the warm air curtain of the factory building of industrial and mining enterprises and storehouse door.

Concrete structure of the present utility model is done further narration in conjunction with the accompanying drawings.
