Pre-thickening Screw Press Sludge Dewatering Machine

Consultation

Product overview: The sludge dewatering machine used for direct sludge dewatering (integrated thickening and dewatering).

Product features: Under normal conditions, the sludge dewatering machine will not pollute the workshop The dewatering main body of the machine consists of the thickening section and the dewatering section, in which the spiral axis runs through, and the thickening section and the dewatering section are respectively composed of the fixed ring and the movable ring. Driven by the screw shaft, the equipment is suitable for continuous automatic operation 24 hours a day.

Equipment Advantages

The Pre-thickening sludge dewatering machine is used for direct sludge dewatering:

1、This equipment is used for direct sludge dewatering (integrated thickening and dewatering machine). The sludge concentration can be 2000mg / L.

2、No clogging, reduce washing water consumption, save cost, and reduce internal circulation burden.

3、The control cabinet, flocculation mixing tank and main body are integrated to reduce the footprint, and the installation is simple and convenient.

4、The dewatering machine is in closed operation, and the treatment is stable and timely, so as to minimize the odor on site and improve the working environment.

5、24 hours continuous automatic running, low laborwork.

6、The screw shaft runs in low speed, low power consumption and basically no vibration and noise on site

7、Easy maintainance

Structure

Main body      

      The main body of the sludge dewatering machine is composed of multiple fixed rings and moving rings, and the screw shaft runs through the filtration device formed therein. The former section is the thickening section, and the latter section is the dewatering section. The thickening and dewatering of sludge are completed in one cylinder, replacing the traditional filter cloth and centrifugal filtration mode.

Pre-thickening System

The pre-thickening system is mainly composed of thickening rings, mixing blades and thickening tank.

The mixing system is mainly used to fully mix the sludge and polymer in the thickening tank. The sludge is flocculated and agglomerated. At the same time, part of the water is filtered by gravity from the thickening rings, and the sludge flocs is pressed into the main body of the machine for dewatering. The mixing tank is provided with a mud inlet, an overflow port, a dosing port and a vent port, and a liquid level regulating device, so as to adjust the sludge feeding amount.

Dewatering Principle

After gravity thickening in the thickening section, the sludge is transported to the dewatering section. In the process of advance, with the gradual decrease of the filter joint and pitch, and the blocking effect of the back pressure plate, a great pressure is generated, and the volume is constantly reduced, so as to achieve the purpose of fullly dewatering.


  

Product Advantages

1、Wide application

  Widely used for all industries include municipal, food, drink, slaughtering, printing, oil, paper, leather and chemical etc.

应用范围广

      Special dewatering principle, makes this equipment suitable to handle high and low solids content sludge. TSS start from 2000mg/Lfirst dewatering unit that can treat the low solids content sludge.


浓度

Innovative structure design, makes the equipment suitable for all kinds sludge type. Especially oily sludge.

2、No clogging easily

  Special structure of moving and fixed rings, makes the equipment not clogging easily, no need of large washing to prevent clogging. Save washing water and lower the internal burden.

3、Continuous & automatic running

1258661224

From sludge feed, polymer dose, cake discharge all controlled and connecte together by the panel. For the first time, continuous running 24 hours a days is achie ed. 









4、Running cost saving

   Low speed screw pressing technology, greatly reduce the electricity consumption, no clogging, greatly reduce the wash water, automatic no-man watching running, greatly reduce the labor cost.

5、No 2nd pollution

  Speed of screw shaft is 2~3rpm, no vibration, low noise; The structure can clean itself, no clogging, no 2nd pollution; Slow running mode, the smell will not spread.


 6、Durable and light structure

  Direct mechanical dewatering, no need of rotary drum, so the machine is light; The machine is made completely by stainless steel, only screw shaft and moving rings need to be replaced. Longer lifespan.

7、Saving civil investment

  As screw press is integrated with sludge thickening function. It can handle the sludge directly from the settling tank. No need of thickening or storage tank, so as to reduce the civil footprint and conscturction cost.

8、Improve phosphorus removal

  Sludge is dewatered under aerobic condition, the phosphorus will not release like traditional sludge thickening tank. So to prove the phosphorus removal function of the whole system.
