Problem Statement
- Transport infrastructure such as roads are prone to large amount of dust particles which are mostly fine in nature and may damage internal organs if breathed in through air.
- To remove road dust deposit, conventional method is to collect dust/waste from roads manually, but that causes resuspension resulting in high Particulate Matter(PM) concentration rise in the local air environment.
- Alternatively, a few devices with power intensive or complex collection mechanism are used, but said devices are expensive & also may not be accessed in all places.
- Hence there is a need to introduce a low cost, simple in the construction & sustainable technology that helps in improving the life quality and can be produced in a decentralized market. This patent discusses a tricycle-based dust collector that addresses all the above mentioned issues.
Technology
- In the present invention, a road dust collector device mounted on a wheeled assembly and a method of collecting dust using the device thereof is provided.
- The Device consists of a set of six cyclone separators mounted on a tricycle (FIG 2).
- The tricycle-based dust collector works on mechanical agitation created by rotation of the self-adjusting brush assembly which adjusts its height according to the variation in altitude so that it do not leave surface contact from road.
- This may happen due to the slope variation & road roughness change.
- The device is configured to sweep dust from a surface using a sweeping arrangement, that includes a plurality of rotatable self-adjustable brush assemblies that is configured to pick up dust by mechanical agitation created by rotation of the self-adjusting brush assembly that adjusts height via a spring-loaded link mechanism, suck the dust into a cyclone separator and separate the dust particles from the clean air.
- It ensures that there is always a negative pressure created with in the enclosure which is covered on sides using rubber flaps so that the agitated dust particles do not escape out of it.
Key Features/Value Proposition
- Simple mechanism of agitation & suction using a low power consuming fans attached at cyclone separators outlet; making technology sustainable.
- Useful in dust management and control of dust emission from the road, resulting in low PM concentration management in the local environment.
- Cheaper in price in terms of Simple construction & easy operation and affordable.
