Low, occupied area is small.Wherein filter press is 15, filter cylinder 2, foundation of civil work 16.
Include below step when specifically being implemented:
First step sludge flocculation:
1) 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 calculates to obtain 0.19m/s,
That is movement speed of the sludge in filter cylinder.
Setting flocculation sink effective length L=1000mm, the sink diameter 150mm that flocculates 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 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) calculating of flocculation time.(setting technique requires minimum flocculation time >=15s)
Flocculate sink flocculation time: at 5 ° of angles, the sink that flocculates turns setting flocculation sink relative level central axis from location A
B location is moved, for incorporation time of flocculating, is rotated with the speed of 3r/min, i.e. 20s/r.A point to B point rotation time * * 20=
The effective flocculation time 3.75s of 3.75s, i.e. sludge.It is 20=1.25s of liquid time * * out from B point to C point.From A point to the wadding of C point
The solidifying liquid time out is * 20=5s of 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: revolving 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.(turning 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) calculating for the torque and power of intaking.
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.
0.5 ~ 1 cubic metre of flocculation cylinder power of agitator 0.75kw originally individually set up can cancel.
Second step gravity dehydration:
Spiral in closed cylinder is flocculated liquid out, is pushed by continuous variable-pitch auger blade to screen tube, filter
Net cylinder rack is fixedly connected with central axis for steel pipe, and machine frame inside is welded with helical blade (left-handed), and spiral number 2.5 encloses, 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 constantly stirred toward rear class with 0.19m/s linear velocity and is pushed, 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 step gravity concentration:
Sludge pushes to conical screen cylinder by continuous helical blade, since conical screen cylinder is to the castering action of sludge,
So that sludge is concentrated dehydration moisture content into one and is reduced to 86% or so.
