Include below step when specifically being implemented：
First step sludge flocculation：
1）The setting of general parameters.
Roller is set to rotate with the speed of 3r/min, diameter of phi 1.2m outer cylinder linear speed Π * d*n calculate to obtain 0.19m/s,
That is movement speed of the sludge in filter cylinder.
Setting flocculation sink effective length L=1000mm, flocculation sink diameter 150mm add water to highest liquid such as figure section
Half of the volume V=Π * r2*L/2 in position calculates to obtain 0.0081m3/.
It sets flocculation water slot number amount and is distributed in cylinder inner wall as 16, calculate 3 × 16 × 0.0081=0.39m3/ of inflow
min.That is the actual treatment amount 23m3/h of roller.
2）The calculating of flocculation time.（Set the minimum flocculation time >=15s of technological requirement）
Flocculate sink flocculation time：Setting flocculation sink relative level central shaft is turned at 5 ° of angles, flocculation sink from location A
B location is rotated, i.e. 20s/r for incorporation time of flocculating with the speed of 3r/min.A points to B points rotation time * * 20=
The effective flocculation time 3.75s of 3.75s, i.e. sludge.It is 20=1.25s of liquid time * * from B points to C points.From A points to the wadding of C points
Coagulate * 20=5s that the liquid time is roller.
Spiral flocculation time：The low pitch angle of 1.5 circle of setting is continuous in closed cylinder in flocculation sink rear class processing
Blade pitch P=200, the purpose is to increase flocculation time.It is directly entered the section after flocculation sink water outlet, continues the mixing of muddy water
Flocculation.In setup parameter：Rotating speed 3r/min, i.e. 20s/r, spiral number=1.5P.Because of 1P=1r=20s, rotated in roller
The middle most short maximum duration of spiral flocculation time is 0.5 × 20=10s and 1.5 × 20=30s respectively.
Conclusion：Sink flocculation+spiral flocculation, total muddy water flocculation time：Between 5+10=15s and 5+30=35s.Meet work
Skill requirement.（Being turned down when drum rotation speed can be by the spiral number of turns of increase and decrease flocculation section, to meet the flocculation time to sludge
It is required that）.
3）Into the calculating of Hydraulic Moment and power.
The volume 0.0081m3 of known single sink, by the density 1t/m3 of water, the gravity of generation is 8.1kgf；By 1kgf=
9.8N, i.e. ,=79.38N.
By torque formula：T=FA.Known gravity F=79.38N, arm of force A=0.52m,.
T=FA=79.38*0.52=41.28N.m；T1=F1A=Fcos22*0.52=38.27N.m；
T2=F2A=F cos45*0.52=29.17N.m； T3=F3A=F cos68*0.52=29.76N.m；
Resultant couple Tz=T+T1+T2+T3=124.2 N.m。
By horse-power formula P=TzN/9550, Tz=124.2 N.m N=3r/min.Calculate to obtain P=39W.
Original 0.5 ~ 1 cubic metre of flocculation cylinder power of agitator 0.75kw individually set up can cancel.
Second step gravity dehydration：
Spiral in closed cylinder is flocculated liquid, is pushed to screen tube, screen tube by continuous variable-pitch auger blade
Rack is fixedly connected with central shaft for steel pipe, and machine frame inside is welded with helical blade（It is left-handed）, the circle of spiral number 2.5, pitch P=
300.Blade exterior is enclosed with the stainless steel cloth of 20 mesh, and steel wire surrounding is fixed on the rack by pressing plate, steel wire diameter Φ
0.4mm, screen distance reach 0.87 × 0.87mm.Mud, water after flocculation are clearly separated, and with the rotation of helical blade, are deposited on filter
The muddy water of net cylinder bottom is pushed with 0.19m/s linear velocities by continuous stir toward rear class, and water therein is continuous due to gravity
A large amount of abjection, completes gravity dehydration, and moisture content is reduced to 90% or so.
Third walks gravity concentration：
Sludge pushes to conical screen cylinder by continuous helical blade, since conical screen cylinder is to the castering action of sludge, makes dirt
Mud is concentrated dehydration moisture content into one and is reduced to 86% or so.
