Product details:
Working method:The main body of the dehydrator is a filtering device formed by stacking a fixed ring and a moving ring, with a spiral shaft passing through it. It integrates concentration and dehydration, with the front section being the concentration section and the rear section being the dehydration section. Each swimming ring is embedded between two fixed rings, forming a filter gap between them, and the pitch of the spiral shaft gradually decreases from the concentration section to the dehydration section. The inner diameter of the fixed ring and the moving ring is the same as the spiral diameter of the spiral shaft, ensuring almost no wear during operation; There is a back pressure plate at the terminal of the dehydration section that generates internal pressure.
The main body of the stacked snail adopts a tilted installation, and the dehydration part is located at a high position. The entire concentration and dehydration process will have the effect of gravity. The rotation of the spiral shaft drives the moving ring to make circular motion, and the filtering structure composed of the fixed ring and the moving ring is in a moving state, which is not easy to block. Water flows out from the filter slot, playing a self-cleaning role, while the sludge is constantly pushed forward by the spiral shaft. After gravity concentration and low pressure compression in the concentration section, the sludge is transported to the dewatering section. As it moves forward, the concentration of the sludge increases with the decrease of the filter slot and pitch. Under the blocking effect of the back pressure plate, a great internal pressure is generated, and the sludge containsA small amount of water is squeezed out and eventually turns into a mud cake.
Characteristics of the new sludge dewatering technology
1. Unlike other dewatering machines, the laminated sludge dewatering machine belongs to the form of dewatering machine equipped with a thickener. It can also dewater when the inflow sludge is at a low concentration of 2000-5000mg/L;
2. By operating the expansion valve and adjusting the outflow, the sludge concentration can be adjusted at a concentration of 3%;
3. Before flowing into the dewatering machine, the sludge is highly concentrated through the thickener and then transferred to the sludge dewatering machine, which has the effect of increasing moisture content and processing capacity
Compared with the centrifugal dehydrator's rotation speed of 3000rpm, rotating at a low speed of around 2rpm results in very low noise and almost no vibration;
5. Using 20m3/According to HR standards, the power of centrifugal dewatering machines from other companies is around 37kw, but when combined with multiple disc dewatering machines, the power of the concentrator is around 3kw, which has a 1/10 energy-saving effect;
6. Unlike existing dewatering machines, the aeration tank directly removes activated sludge, which can solve the odor problem that occurs in the concentration tank and subsurface flow tank, and also save the construction cost of the concentration tank and subsurface flow tank
