5.This machine has many different models including different capacities from 100kg/day to 2000kg/day. So it could be used at home, restaurant, hotel, school canteen and so on.
Main Parts:
Sludge concentration & dewatering Body; Flocculation & Conditioning Tank; Integrate Automatic Control Cabinet; Filtrate Collection Tank
Working Principle:
Force-water concurrent; Thin-layer dewatering; Moderate press; Extension of the dewatering path
It has solved several technical problems of other similar sludge dewatering equipment including belt presses, centrifuge machines, plate-and-frame filter press have, which are frequent clogging, low concentration sludge / oil sludge treatment failure, high energy consumption and complicated operation etc
Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank for gravity.
Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produce.
Self-cleaning: The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering equipment.
Product Feature:
Special pre-concentrating device, wide feed solids concentration: 2000mg/L-50000mg/L
The dewatering part of MSP consists of a thickening zone and a dewatering zone. In addition, a special pre-concentrating device is mounted inner the flocculation tank. Therefore, the wastewater with rather low solids content is not a problem to MSP. The applicable feed solids concentration can be as very wide as 2000mg/L-50000mg/L.
Since MSP can be used directly to concentrate and dewater the low-solid sludge from aeration tanks or secondary clarifiers, the users don't have to build a thickening tank or a storage tank any more while they have to when using other types of sludge dehydrators, especially the belt filter presses. Then significant civil engineering cost and floor area are saved.
machine screw volute sludge dewatering press for sludge dewatering treatment
The spiral type sludge dewatering machine is a kind of water treatment system, which is widely used in municipal wastewater treatment engineering, petrochemical, light industry, chemical fiber, paper making, pharmaceutical, leather and other industries.

KJG series Paddle Dryer / Processor are highly efficient, mechanically agitated, indirect heat transfer devices that add or remove heat from a process mass. They are used for drying, heating, cooling, pasteurization, crystallizing, and reacting of pastes, cakes, powders, and granules.
Dual counter-rotating shafts with unique intermeshing discs produce intimate mixing and optimize heat transfer. The use of hollow discs and drying chamber heating jacket for heat transfer results in a compact machine. The heat transfer medium: steam, hot water or hot oil is isolated from the process mass. The KJG series Paddle Dryer provides a reliable and efficient method for drying slurry, filter cakes and centrifuge concentrates.
The exhaust gases can be treated by cyclone, condenser and scrubber to considerably reduce air contamination. For those wet materials of heat sensitive, easy oxidized, containing organic solvents which need to be recovered, vacuum design is available.
Technical advantages
1) High thermal efficiency which can reach 95%
2) Heat transfer medium does not contact the product.
3) Gas is not used to convey the product. Off-gas flow is minimal.
4) Precise control of temperature
5) Uniform product quality, through mixing and movement of the product
6) Continuous process on a once-through basis
7) High heat transfer area to process volume ratio - reduced floor space
8) Easy to operate, requires minimal attention
9) Safer than direct drying when processing combustible material
10) Simple durable design for easy and low maintenance
11) Dual counter-rotating shafts with unique intermeshing discs produce intimate mixing, uniform heat transfer, a high heat transfer rate, and a self-cleaning effect.A large heat transfer area to volume ratio is achieved by the use of hollow discs and a jacketed vessel, through which the heating medium flows. The result is a compact machine with less space requirements and lower installation cost.
12) The KJG series Paddle Dryer transports material, regardless of its handling characteristics. Sticky, pasty materials can be transported. Pre-conditioning the feed by mixing with recycled dried product, to make it conveyable, is not required. This results in lower capital, operating, and maintenance cost.
