TPDL Volute screw sludge thickener
Volute screw sludge thickener inherits the technical advantages of low energy consumption, high efficiency, fully automatic control and stable operation of Volute screw sludge dewatering machine. The sludge can be condensed rapidly and continuosusly in the secondary sedimentation tank, and the sludge concentration can be adjustable within the range of 90%~96% after concentration and separation. After using this equipment, a concentration tank is not necessary, construction investment and land occupation can be reduced, the odor and phosphorus release caused by the concentration tank sludge can be effectively reduced, the burden of subsequent processing can be reduced and the capacity of sludge dewatering and deep dewatering equipment can be significantly increased.

Application:
As a pretreatment equipment for sludge deep dewatering system, it is equipped with high pressure plate frame filter press and diaphragm filter press and etc.
An alternative sludge concentration tank as a pretreatment equipment for the sludge dewatering system;
Used in other concentrated or solid-liquid separation processes.

Construction principle
Volute screw sludge thickener consists of a concentrator, a driving device, a filtrate tank, a mixing system,and a rack . When working, the sludge is lifted to the mixing tank by the sludge pum. Meanwhile, the dosing pump also quantitatively delivers the chemicals to the mixing tank, the stirring motor drives the entire stirring system to thoroughly mix the sludge and the chemicals, thus coagulates into larger alum grains. When the liquid level reaches the upper position of the liquid level sensor, the chemical sensor gets a signal, so that the motor of the screw press works, thus start to filter pressing the sludge into the screw sludge body .Under the action of the screw shaft, the sludge is lifted to the sludge outlet step by step, and the filtrate flows out from the gap between the fixed ring and moving ring.
In a word, volute screw sludge thickner used the principle of spiral extrusion .Through the strong squeezing force generated by the pitch change and the tiny gap between the moving ring and fixed ring, the sludge can be squeezed and concentrated to achieve solid-liquid separation. It is a new equipment for solid-liquid separation.

Product advantages
1. Wide range of sludge concentration, suitable for sludge moisture content range of 98%~99.8%;
2. After the concentration, the moisture content of the sludge is stable and adjustable within the range of 90%~96%;
3. High concentration efficiency and small floor space;
4. No filter cloth, self-cleaning, no clogging, no need for high pressure backwashing water;
5. Low running speed ,low energy consumption, low operating cost, low vibration, low noise;
6. Closed operation to reduce the smell of the sludge;
