Design and Fabrication of Pneumatic Conveyor System
Pneumatic conveying system is a conventional material handling system like belt conveyor or chain conveyor. The main advantage of pneumatic conveying system is that material is transferred in close loop, thereby preventing the environmental effect on the material and vice versa. In these topic different parameters like air velocity, pressure, particle size and shape, distance to be conveyed, which govern the design of the system, are described. The research work carried out on the pneumatic conveying system in the last decade considering these parameters are also presented. No standard procedure is available for the design of pneumatic conveying system. As the configuration of the system changes, variable involved also changes, and one has to change the design considerations based on the applications. So there is wide scope for experimentation in the field of pneumatic conveying system.
The material handling mechanism is achieved by reciprocating the double acting cylinder which is controlled by solenoid operated 5/2 way DC valve which is actuated by ON/OFF relay control system. Here the linear motion of the piston rod is converted to rotary motion of the belt conveyor through the chain and sprocket wheel Mechanism.
In this project we are going design a system where the moving roller of the conveyor is powered by an pneumatic cylinder. Pneumatic cylinder will starts reciprocating and then a power plate with holes on it starts to roll on sprocket. Due to power given by cylinder piston and power plate sprocket starts rotating unidirectional. Hence our belt conveyor is also starts rolling.
Conveyor is used in many industries to transport goods and materials between stages of a process. Using conveyor systems is a good way to reduce the risks of musculoskeletal injury in tasks or processes that involve manual handling, as they reduce the need for repetitive lifting and carrying. Belt conveyor system is the transportation of material from one location to another location. Belt conveyor has high load carrying capacity (up to 30000 t/h), large length of conveying path (up to 3-4 km), simple design, easy maintenance and high reliability of operation. Belt conveyor system is also used various industries such as the material transport in foundry shop like supply and distribution of molding sand, moulds and removal of waste, coal and mining industry, sugar industry, agricultural industry, bagasse industry, fuel industry etc.
This project consists of
1) Belt conveyor assembly
2) ON/OFF relay control
3) 24VDC power supply
4) Sprocket wheel with Power plate
5) Pneumatic cylinder with solenoid valve
