2 B.E., Department of Mechanical Engineering, Dr. Babasaheb Ambedkar College of Engineering & Research, Wanadongari, Nagpur – 441110, Maharashtra. INDIA. -------------------------------------------------------------------***--------------------------------------------------------------------chalk is made from “plaster of Paris and calcium Abstract - The Project is based on the concept of developing carbonate”, that is CaSO4.1/2H20 which is hydrated a mechanism which is used to recover the dust from duster. In short, swallowing a piece of black chalkboard chalk won't kill and allowed to set in fixed If the colored chalks are to a person, but inhaling the dust for a long span can create or be prepared some pigments and dies are added to it trigger respiratory problems. Therefore, it is necessary to have which may be toxic or nontoxic. the ability of automatic cleaning of the duster and also the Studies have shown that limestone (natural chalk) function for collecting the dust so that it cannot permit to fly factory workers have increased prevalence of dust in the atmosphere which causes health hazards. This respiratory symptoms. Results of a survey conducted in project is implemented to make human work easier and can Spain showed that shaking and/or frequent use of the reduce the use of human power because of its potential eraser or of chalk in class was associated with an applications. increased risk of respiratory symptoms. The design is Key Words: Duster cleaning institutional able to achieve automated clean the duster eraser and experimentation, Mechanical Structures, Small Vacuum collect dust in one stroke. In this research paper, Pump, Removable Dust collector etc. concept puts forward a kind of mechanism design scheme, the mechanism can automatically remove the 1. INTRODUCTION chalk dust particle after putting the duster clean in Nowadays projectors are used in the class rooms but it is not feasible and has complex operations so such a fixture and erase the duster Clean, keep the duster device has been made which has the ease and the eraser free from dust particle. simplicity of the blackboard duster cleaning. Writing on the board is very easy job and erasing is still easier one 2. LITERATURE REVIEW the main problem arises when the task of cleaning the Ren, Z. G., Chalk dust on the health hazards of duster eraser comes. After quite some time the duster teachers. Chinese Journal of School Health [1]. eraser becomes saturated and it doesn't clean the black According to the survey and the medical report from board efficiently. Then it needs cleaning. Cleaning the experts and various doctors, it was concluded that the duster eraser is very simple job just rub it or impact it most of the teachers did not know or were ignorant against the wall and most of the dust falls off .Generally about the problems caused by the chalk dust, Chalk the teacher needs to clean the blackboard while he is generates a large amount of airborne dust, and teaching. Banging of duster against the wall produces particularly sub micrometer dust and nano particles noise, destructs the wall texture, makes the class dirty, that can penetrate into the respiratory system. This and worst of all quite a lot of chalk dust is released machine mechanism automatically cleans the duster which, when inhaled can lead to troubles like bronchitis eraser; the only human effort is to do is to placed the that is asthma and lung diseases or if it goes into the duster in the duster cleaning Fixture device. eyes it may cause irritation in the eyes. Chalks (dusty or dustless) are commonly made up of limestone (CaCO3) and/or gypsum (dehydrated form of CaSO4) as their main constituent. Kaolinite (hydrated aluminum silicate), car boxy methyl cellulose (CMC), poly vinyl alcohol, starch are present in small quantities. It may also contain some dross like silica and colored chalks contain some metals. The © 2017, IRJET
