Abstract
Blacksmith generally do the forging operation by hand which requires more time and have survived to exist in rural economy even today. Due to unavailability of electricity and limitation of modern energy sources, economic development of rural area lays extreme poverty line. Development of solar operated blacksmith blower gives a reliable and sustainable solution to blacksmith for their forging operation. This paper represents design and development of solar operated blacksmith blower which was eco-friendly, less time consuming and high efficiency. The main component of solar operated blower is charge controller, battery, solar panel, DC blower and a speed controller. Mathematical calculation had been done for sizing of solar panel, battery, and charge controller and speed controller. The regulation of supplement of air for forging operation with the help of speed controller is the unique design of this research.
Highlights
The rural economy in India is based on agricultural production and agro processing mostly in tiny scale or domestic units
Competition from industrial products, increased cost of raw materials and charcoal, unavailability of charcoal, shortage of labour, additional labour cost to operate the manual blower are all adding to the burden of blacksmiths making it difficult for them to depend on their traditional artisanal work for living
One of the most common issues faced by blacksmiths is shortage of labour to operate the manual blower and huge labour cost which takes away a significant portion of their income
Summary
The rural economy in India is based on agricultural production and agro processing mostly in tiny scale or domestic units. 2. Competition from industrial products, increased cost of raw materials and charcoal, unavailability of charcoal, shortage of labour, additional labour cost to operate the manual blower are all adding to the burden of blacksmiths making it difficult for them to depend on their traditional artisanal work for living. One of the most common issues faced by blacksmiths is shortage of labour to operate the manual blower and huge labour cost which takes away a significant portion of their income. Due to dependency on an additional labour and irregularity with labour turning up for work, labour has become a major operational challenge for blacksmith resulting in loss of income. Even if the blacksmith workshops are connected to grid, due to erratic power cuts in rural areas, these blowers won’t be useful to full extent instead it further increases uncertainty with labour planning and productivity. The main component of solar operated blower is solar panel, charge controller, battery, speed controller
