Fume exhaust funnel cap

Abstract

The invention is suitable for the technical field of environmentally-friendly exhaust equipment, and provides a fume exhaust funnel cap. The fume exhaust funnel cap comprises a funnel cap body, a fumeexhaust assembly and at least one wind power assembly. The fume exhaust assembly is arranged at the bottom of an inner cavity of the funnel cap body in a rotating mode. The at least one wind power assembly is arranged above the funnel cap body and driven by the wind power to rotate. The wind power assemblies drive the fume exhaust assembly to rotate through a transmission mechanism, and the fumeexhaust speed is increased. A sweeping mechanism is arranged below the funnel cap body, connected with the transmission mechanism and used for sweeping fume dust in a funnel. According to the fume exhaust funnel cap, the fume exhaust assembly is driven by the wind power assemblies to rotate, the fume exhaust efficiency can be improved by the wind energy under the windy condition, the fume exhausteffect is not affected or is slightly affected when no wind exists or a breeze exists, and the fume dust accumulated in the funnel can be cleaned away.

Description

technical field [0001] The invention belongs to the technical field of environmental protection exhaust equipment, and in particular relates to a smoke exhaust hood. Background technique [0002] The existing mainstream hoods can be divided into two types: hoods with accelerated smoke and dust (gas) exhaust function and hoods without accelerated smoke and dust (gas) exhaust function. Among them, the wind cap with the function of accelerating smoke and dust (gas) exhaust, represented by the non-powered hood, can discharge smoke and dust (gas) well under windy conditions, but due to the narrow hollow slits, the exhaust resistance is large and the exhaust effect is low. It is limited, and not only fails to discharge the smoke (gas) under the condition of no wind or breeze, but also hinders the discharge of smoke (gas), making the efficiency of smoke and dust (gas) exhaust far less than the traditional one under the condition of no wind or breeze. Hood: Traditional hoods are ge...

Among them, the wind cap with the function of accelerating smoke and dust (gas) exhaust, represented by the non-powered hood, can discharge smoke and dust (gas) well under windy conditions, but due to the narrow hollow slits, the exhaust resistance is large and the exhaust effect is low. It is limited, and not only fails to discharge the smoke (gas) under the condition of no wind or breeze, but also hinders the discharge of smoke (gas), making the efficiency of smoke and dust (gas) exhaust far less than the traditional one under the condition of no wind or breeze. Hood: Traditional hoods are generally divided into umbrella-shaped hoods, conical hoods and cylindrical hoods, none of which have the function of accelerating smoke and dust (gas) exhaust; and the current chimney will have a large amount of smoke and dust accumulation after a long period of use, which is difficult to clean
