Spiral discharge sedimentation centrifuge is located on horizontal station table top, and spiral discharge sedimentation centrifuge is for handling sludge and obtaining
The sludge outlet of dewatered sludge and water, spiral discharge sedimentation centrifuge is connected with sludge bucket, sludge bucket by sludge pipe
On the bracket below station, the separation water outlet of spiral discharge sedimentation centrifuge is connected to pond by outlet pipe.
Further, the height of station is greater than the height of sludge storage pool and pond.
Further, it is provided with check-valves on outlet pipe and sludge pipe, the check-valves of sludge pipe is located at along sludge flow direction
After sludge pump.
Further, the caliber of sludge pipe is DN50, and the caliber of outlet pipe is DN100.
Further, regulating valve is additionally provided on sludge pipe.
The beneficial effects of the utility model are: the utility model using spiral discharge sedimentation centrifuge to sludge at
Reason, the ability for handling sludge increase, and generate dewatered sludge daily and increase about 10 tons；Dewatered moisture percentage in sewage sludge is low,
Generally 40% or so, facilitate roping, processing；Mud site environment is pressed to improve obvious, pressure mud overall process free from extraneous odour generates；Spiral is unloaded
Expect that sedimentation centrifuge construction is simple relative to belt pressure mud machine, component is few, and spare part selection quality is high, generally stainless steel material,
Therefore the maintenance of equipment frequency is low, convenience easy to maintenance, and the cycle of operation is long.

[specific embodiment]
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The utility model discloses a kind of systems for handling biochemical sludge, as shown in Figure 1, include sludge storage pool 1,
Sludge storage pool 1 is connected for storing sludge caused by factory, the sludge outlet of sludge storage pool 1 by sludge pipe 8
To spiral discharge sedimentation centrifuge 3, the sludge of sludge storage pool 1 is entered in spiral discharge sedimentation centrifuge 3 by sludge pipe 8,
Model LW380 × 1520-N of spiral discharge sedimentation centrifuge 3, roller diameter 380mm, main motor current 22KW.
Spiral discharge sedimentation centrifuge 3 is located on horizontal 6 table top of station, and the height of station 6 is stored greater than sludge
The height in pond 1 and pond 5 can guarantee water that the spiral discharge sedimentation centrifuge 3 on station 6 is isolated without any in this way
Pressure can flow into pond 5 by outlet pipe 9, it is also ensured that the dewatered sludge of spiral discharge sedimentation centrifuge 3 is along row
Mud pipe 10 falls naturally, and falls into sludge bucket 4.
Sludge pipe 8 is connected with sludge pump 2, and sludge pump 2 is used to pressurize to by the sludge of sludge pipe 8, enables sludge
Rapidly enter spiral discharge sedimentation centrifuge 3, sludge pump 2 simultaneously can also be to avoid the slow blocking pipeline of sludge stream speed, on sludge pipe 8
It is additionally provided with check-valves, along the direction of sludge flow direction, check-valves is located at after sludge pump 2；Check-valves is for controlling sludge pipe 8
The sludge one-way movement of inner cavity prevents sludge from reversely flowing into sludge pump 2, damages sludge pump 2.
Spiral discharge sedimentation centrifuge 3 is unloaded according to isolated principle, i.e. realization solid and liquid separation into spiral
The sludge of material sedimentation centrifuge 3 obtains dewatered sludge and water after centrifugal treating, and dewatered sludge passes through sludge pipe
10 enter sludge bucket 4, to further handle.
The sludge outlet of spiral discharge sedimentation centrifuge 3 is connected with sludge bucket 4 by sludge pipe 10, and sludge bucket 4 is located at
On the bracket 7 of 6 lower section of station, self-assembling formation difference in height, guarantee is isolated dewatered through spiral discharge sedimentation centrifuge 3
Sludge can fall naturally from sludge pipe 10, fall into sludge bucket 4, sludge pipe 10 and the table top of station 6 are mutually perpendicular to, de- to facilitate
Sludge after water, which is taken advantage of a situation, falls into sludge bucket 4.
Sludge bucket 4 is located on bracket 7, and bracket 7 is maintained a certain distance with ground, can convenient for the operation of further cake of press
Direct pressing is carried out to place cake of press device under bracket 7, can also directly be opened haulage vehicle to frame 7, it will be in sludge bucket 4
Dewatered sludge transport, and carry out the operation of cake of press.
The separation water outlet of spiral discharge sedimentation centrifuge 3 is connected to pond 5 by outlet pipe 9, heavy through screw unloading
The water that drop 3 centrifugal treating of centrifuge obtains is discharged into pond 5 by outlet pipe 9, facilitates recycling, is provided with only on outlet pipe 9
Return valve, check-valves is used to control the water one-way movement of 9 inner cavity of outlet pipe, can only flow out, cannot blow back into spiral discharge settling from
Scheming 3, with anti-tamper spiral discharge sedimentation centrifuge 3.
The caliber of sludge pipe 8 is DN50, and regulating valve is additionally provided on sludge pipe 8, guarantees 3 energy of spiral discharge sedimentation centrifuge
Sufficiently sludge is separated, therefore the caliber for controlling sludge pipe 8 is most important, regulating valve can also be as needed to sludge pipe
Flow in 8 is controlled, and can also be adjusted with the size of foundation sludge moisture content to the flow in sludge pipe 8.
The caliber of outlet pipe 9 is DN100, and it is to avoid sludge that the caliber of the outlet pipe 9 of setting, which is greater than the caliber of sludge pipe 8,
Water content is too high, and after 3 centrifugal treating of spiral discharge sedimentation centrifuge, obtained water is too big, can not be in time from outlet pipe 9
Discharge in time, therefore the caliber by the setting of the caliber of outlet pipe 9 greater than sludge pipe 8.
