Description
Technical field
The present invention relates to the aeration structure in a kind of elevator car systems, the aeration structure of a kind of elevator ceiling.
Background technology
Lift car ceiling generally includes the ventilation duct or ventilating duct allowing air-flow to flow between lift car and elevator hoistways.Ventilating fan promote the air-flow velocity in ventilating duct.Generally, in use the air in elevator hoistways enters directly in lift car through ventilation duct or ventilating duct, promotes the air circulation in lift car.But often it is mingled with dense machine oil taste and/or rust taste due to the air in elevator hoistways in actual use, the most also can carry substantial amounts of granule dust, the most above-mentioned air will enter directly in lift car, affect the air quality in lift car, thus affect the riding quality of whole elevator.
Summary of the invention
The invention aims to solve above-mentioned the deficiencies in the prior art and provide the aeration structure of a kind of elevator ceiling, this aeration structure can remove the abnormal flavour in ventilating air effectively, filters out the granule dust in air simultaneously.
To achieve these goals, the aeration structure of a kind of elevator ceiling designed by the present invention, ceiling portion including lift car, in ceiling portion, wherein it is provided with the ventilating path for the circulation of lift car inside and outside air, every being provided with the active carbon layer wrapped up by eptfe film in the cross-wise direction of above-mentioned ventilating path.
Expanded PTFE (expanded PTFE) in above-mentioned is a kind of novel medical macromolecular materials, it is made up of polyflon drawn, foaming, it has a performance of the highest waterproof and dustproof and ventilation, and therefore air can effective filter out granule foreign when through above-mentioned thin film；In eptfe film, the activated carbon of parcel is again the most tiny a kind of carbon granule simultaneously, there is the biggest surface area, and carbon granule also has more tiny hole capillary tube, this capillary tube has the strongest absorbability, owing to the surface area of carbon granule is very big, so can be fully contacted with gas (impurity), encounter capillary tube when these gases (impurity) and be adsorbed, aseptic, effectively remove air entrainment of abnormal flavour.
In use for some time, in order to collect the granule dust being deposited in outside eptfe film easily, promote stability in use and the effectiveness of the present invention, it is additionally provided with dust collecting box in the ceiling portion of above-mentioned lift car, this dust collecting box is connected with described ventilating path by an airduct, 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 improving, above-mentioned ventilating path is a ventilating duct, this ventilating duct contains the first wind passage mouth and the first baffle plate and the second wind passage mouth being positioned on its bottom surface and second baffle being positioned on ceiling portion end face, wherein the first baffle plate and second baffle are between the first above-mentioned 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 fixing end, and its other end is fixed on above-mentioned second baffle.Ventilating duct in this preferred version uses the first wind passage mouth and the second wind passage mouth deviated from each other, and the first baffle plate and the second baffle air to flowing through that arrange monoclinic phase pair in the intermediate cavity between the first wind passage mouth and the second wind passage mouth carry out water conservancy diversion, the air flow process passing through this ventilating duct increases, thus reduce the hoistway noise entering lift car through ventilating duct, improve the riding quality that lift car is overall.
The aeration structure of the elevator ceiling that the present invention obtains, the cross-wise direction of the ventilating path for the circulation of lift car inside and outside air has set the active carbon layer wrapped up by eptfe film, make the air in elevator hoistways first can be filtered off granule foreign by eptfe film before entering lift car, simultaneously the most again by active carbon layer remove entrainment of abnormal flavour, thus under the air circulation premise in ensureing lift car, it is effective to ensure that again the air quality entering lift car.The air duct structure of the most above-mentioned ventilating path prioritizing selection air long flow path, is to farthest reduce the noise impact on lift car in elevator hoistways, in order to the farthest riding quality of hoisting elevator car.
