Description

The aeration structure of elevator ceiling

Technical field

The present invention relates to the aeration structure of aeration structure, particularly a kind of elevator ceiling in a kind of lift car system.

Background technology

Lift car ceiling generally includes and allows air-flow mobile breather pipe or air flue between lift car and elevator hoistways.Ventilating fan promotes the air-flow velocity in air flue.Conventionally, in use the air in elevator hoistways directly enters in lift car through breather pipe or air flue, promotes the circulation of air in lift car.But in actual use because the air in elevator hoistways is often being mingled with dense machine oil taste and/or iron rust taste, also can carry a large amount of granule dusts simultaneously, therefore above-mentioned air will directly enter in lift car, affect the air quality in lift car, thereby affect the riding quality of whole elevator.

Summary of the invention

The aeration structure that the object of the invention is to provide in order to solve above-mentioned the deficiencies in the prior art a kind of elevator ceiling, this aeration structure can be removed the peculiar smell in ventilating air effectively, filters out airborne granule dust simultaneously.

To achieve these goals, the aeration structure of the designed a kind of elevator ceiling of the present invention, comprise the ceiling part of lift car, wherein in ceiling part, be provided with the ventilating path for lift car inside and outside circulation of air, in the cross-wise direction of above-mentioned ventilating path every being provided with the active carbon layer wrapping up by eptfe film.

Expanded PTFE (expanded PTFE) in above-mentioned is a kind of novel medical macromolecular materials, made by teflon resin drawn, foaming, it has very high waterproof and dustproof and the performance of ventilation, therefore air filtering granule foreign effectively in the time seeing through above-mentioned film; The active carbon simultaneously wrapping up in eptfe film is again a kind of very tiny carbon granule, there is very large face area, and in carbon granule also have more tiny hole---capillary tub, this capillary tub has very strong adsorption power, because the face area of carbon granule is very large, so can fully contact with gas (impurity), encounter capillary tub when these gases (impurity) and be adsorbed, aseptic, effectively removes the peculiar smell that air is being carried secretly.

In use for some time, in order to collect easily the granule dust being deposited in outside eptfe film, promote stability in use of the present invention and validity, in the ceiling part of above-mentioned lift car, be also provided with dust collecting box, this dust collecting box is by an airduct and the connection of described ventilating path, wherein the interface of airduct and ventilating path is positioned at the top of active carbon layer, and is serially connected with negative-pressure air fan on described airduct.

As further improvement, above-mentioned ventilating path is an air flue, this air flue has comprised the first wind passage mouth and the first baffle plate being positioned on ceiling part end face and has been positioned at the second wind passage mouth and the second baffle on its bottom surface, wherein the first baffle plate and second baffle are between above-mentioned the first wind passage mouth and the second wind passage mouth, and mutual skew symmetry between the two, one end of active carbon layer is fixed on the first above-mentioned baffle plate, and the interface of described airduct is positioned at the top of this fixed end, its other end is fixed on above-mentioned second baffle.Air flue in this preferred version adopts the first wind passage mouth and the second wind passage mouth that mutually depart from, and the first right baffle plate of monoclinic phase and second baffle are set in the intermediate cavity between the first wind passage mouth and the second wind passage mouth the air of flowing through is carried out to water conservancy diversion, the air flow process of this air flue of making to flow through increases, thereby reduce the hoistway noise that enters lift car through air flue, improved the riding quality of lift car entirety.

The aeration structure of the elevator ceiling that the present invention obtains, in the cross-wise direction of the ventilating path for the inside and outside circulation of air of lift car, establish the active carbon layer wrapping up by eptfe film, make air in elevator hoistways enter first can be by eptfe film elimination granule foreign before lift car, the peculiar smell of simultaneously except deentrainment by active carbon layer again, thereby under the circulation of air prerequisite ensureing in lift car, the air quality that can effectively ensure to enter again lift car.Above-mentioned ventilating path is preferentially selected the air duct structure of air long flow path simultaneously, is in order farthest to reduce the impact of noise on lift car in elevator hoistways, so that the riding quality of maximum hoisting elevator car.
