Introduction:
Techase® Multi-plate Screw Press, developed by Shanghai Techase Environment Protection Co., Ltd with under cooperation with Tongji University, is a new, simple, easy-to-operate sludge dehydrator with low capital outlay and maintenance cost, which can solve the problems that traditional facilities usually have: Plugging, great power consumption, complicated operation and maintenance, not applicable to low-concentrated sludge and oily sludge., not able to operate continuously.
Applicable Fields:
The multi-plate screw press can be widely used in municipal waste water treatment engineering as well as the water treatment systems of industries like petrochemical processing, light industry, chemical fiber, paper-making, pharmacy and leather etc.
Operating Principle:
The thickened sludge was transferred to the dewatering zone from thickening zone, the gaps between the rings and screw pitch gradually get narrower, and the end plate blocks the flow, thereby, narrowing of the volume and increasing of the pressure encourage the dewatering process.
Procucts Advantages:
Special pre-concentration design of rotary disc. Applicable concentration: 2000mg/L-50000mg/L
The main machine of the multi-plate screw press contains both concentration part and dewatering part and therefore the treatment of high concentration sludge and direct dewatering of low concentration sludge are allowed. The special rotary disc pre-concentration device of Techase is better for treating low concentration sludge. The available range of the sludge concentration can be 2000mg/L-50000mg/L.
Low Capital Investment & High Treatment Effect
-need no sludge thickeners, mixers, air compressors, flushing pumps and other auxiliary equipments
-occupy smaller area
Fixed/movable rings instead of filter cloth, self-cleaning, clogging free
As for the multi-plate screw press, under the rotation of the screw shaft, the movable plate slips continuously in relation to the fixed plate, realizing continuous self-cleaning and preventing clogging that happens frequently to traditional dewatering equipment. So the multi-plate features strong oil sludge treatment capability, easy separation and clogging free in addition to clean, odor free, secondary pollution free and no more water required for high pressure cleaning.
Low speed, low noise, low energy consumption - only 1/10 as that of belt machine and 1/20 as that of centrifugal machine.
The dewatering of the multi-plate screw press is performed based on the internal volume pressure, no large-sized body such as roller is needed and further more the operating speed is low - only 2-4 r/min, so it can realize water-saving, energy saving and low noise. The average energy consumption is only 1/10 as that of belt machines and 1/20 as that of centrifugal machines and the unit power consumption is only 0.01-0.1kwh/kg-DS.
Full-automatic control, easy operation and management
The multi-plate screw press is provided without filter cloth and filter openings which are liable to clogging, so the operation is easy. The process is settable according to the operation schedule of the customer and based on the automatic control system, realizing full automatic and unattended operation.
Shanghai Techase Environment Protection Co., Ltd, whch was invested by Tongji University as a key state-level high-tech enterprise, provides services covering the area of waste water, sludge treatment, solid-liquid separation.
