OBJECTIVE
Ø To design and fabracation of automatic drainage cleaning
system
INTRODUCTION
Ø Automatic Drainage Water Cleaning overcomes all sorts of
drainage problems and promotes blockage free drains
promoting continuous flow of drain water.
Ø In the modern era there have been adequate sewage
problems where sewage water needs to be segregated to
clean our surrounding environment.
Ø The waste and gases produced from the industries are very
harmful to human beings and to the environment.
Ø Our proposed system is used to clean and control the
drainage level using auto mechanism technique.

The usage of mechanical drainage cleaner to replace the manual work
required for drainage cleaning system. Drainage pipes are very dirty.
Sometimes it is harmful for human life while it is need for cleaning drainage
system.

They designed their project different way clearance of gaseous substance
are treated separately so the flow of water efficiently. This project may be
developed with the full utilization of men, machines,
and materials and money.

uses for drainage cleaning system because E-bucket lifted a sewage
and used evaporation treatment for this sewage wet sewage was converted
into dry matters, with the of ARM board (ARDUINO) this process was
performed.

explained flow of used water from homes, business industries,
commercial activities is called waste water. 200 and 500 liters wastage water
are generated each person every day. So using waste water technology that
removes, rather than destroys, a pollutant in a drainage system.

DESIGN CALCULATION
DESIGN OF SHAFT:
Material used=Mild steel.
Length=910mm
Inner Diameter=21mm
Outer Diameter=24mm
Length between shaft to shaft=930mm
Power transmitted by the shaft = 108577.5105watt
Maximum Bearing Load : L/� = 248.256/ 9.81
= 25.3064Kg
Area:
A = /4 [D02 -DI2]
= /4 [242 -212]
A = 106 mm2
Direct compressive due to axial thrust :
σ = P/A
= 930/106
= 8.7mpa
.
Bending stress :
σd = P............

= 16.98 N/mm2
= 16.98 mpa
compressive stress :
σc = σo + σd
= 8.7 + 16.98
= 25.68 mpa

DESIGN OF COLLECTING BIN
DESIGN OF SPROCKET
pitch(P) = 12.7 mm
width = 30 mm
teeth =45 mm
Transmission ratio:
i = n1/n2
= 130/75
i =1.75
Pitch:
Z1 = 25
Z2 = i X Z1
= 1.73 X 25
Z2 = 43.25
.
Pitch diameter of sprocket :
d1 = P/(sin(180o/25))
= 12.7/(sin(180o/25))
d1 = 101.6 mm
d2 = P/(sin(180o/22))
= 12.7/(sin(180o/42.25))
d2 = 174.21 mm
DESIGN OF BEARING
Outer Diameter of Bearing (D) = 37 mm
Thickness of Bearing (B) = 12 mm
Inner Diameter of the Bearing (d) = 15 mm
r₁ = Corner radii on shaft and housing
r₁ = 1(From design data book)
Maximum Speed = 14,000 rpm (From design data book)
Mean Diameter (dm) = (D + d) / 2
= (37 + 15) / 2
dm = 26 mm
