Group 7's project is an automatic sand filter machine. It uses a horizontally mounted motorized shaft connected to a filter frame with mesh. As the motor turns the shaft, it reciprocates the filter frame to separate sand from unwanted particles. Components include a mesh filter, motor, mounts, connecting rod and supporting frame. Calculations were done to determine the required motor power and efficiency. The total estimated cost is Rs. 6500. The automated design aims to reduce time, effort and costs compared to manual sand filtering.

- 3. ABSTRACT Here we use a motorized shaft that is mounted horizontally using mounts . The shaft is connected to a filter frame with mesh below and enclosing the frames on the sides . We have rod connected from the shaft to the filter frame in away such us to achieve the best horizontal motion. Also , we have frame to hold the filter frame in place while ensuring proper horizontal motion at the same time . On switching on the motor using our motor controller circuit , the system allows to operate the motor This allows us to operate the sand filter motion for appropriate sand filtering need .
- 4. INTRODUCTION Here we demonstrate the design and fabrication system. Sand is used in construction, manufacturing and many industries. Sand needs to be filtered and separated from unneeded particles, stones and other large particles before it is put to use
- 6. COMPONENTS Mesh : used as the filter Motor: used for the rotary motion motor specification : rated speed=1500rpm,rated voltage=230v rated current=15A ,power=3.5kw Mount : supports the roller Roller : used for the reciprocating motion Connecting rod : which connect motor disc and mesh Supporting frame: which supports the whole system and also resist the vibration

- 11. Design calculations Weight of the sand = 30 kg Radius of the disc =0.04 m Torque=force x radius of the disc input power= (V x I) kw power required to run the motor, P=(2πNT)/60 where N is the speed of motor T is the torque developed
- 12. calculations Power input= 230 X15= 3.450kw Torque =30x9.81x .04 =11.772 Output Power=2x3.14x1500x11.772/60 =1.849kw Efficiency =power o/p/power i/p =1.849/3.450=54%

- 15. ESTIMATED COST TOTAL COST OF OUR PROJECT IS Rs 6500
- 16. CONCLUSION we have designed this product with the intention of replacing the existing manual sand filtering with Automated sand filter machine. As a result time consumption ,human effort ,labour force ,cost of labour , etc Can be reduced.
