Stacked Screw Sludge Dehydrator Scope of application
, can be widely used in sludge dehydration in various industries such as municipal administration, food and beverage, slaughtering and breeding, printing and dyeing, petrochemicals, papermaking, leather, pharmaceuticals, etc.
, suitable for high and low concentration sludge, Since /, it has pioneered the direct dehydration of low-concentration sludge. It is suitable for various types of sludge with high and low viscosity, especially oily sludge. It can be called a powerful tool for dehydration of oily sludge.
The operating principle and main structure of the spiral sludge dewatering machine
The spiral sludge dewatering machine is composed of the spiral body, filter device, liquid collection tank, driving device, flocculation tank, support frame, etc. . When the sludge dewatering machine is working, the sludge is pumped up to the flocculation tank through the sludge pump, and the chemical liquid is also transported through the dosing pump. The stirring motor starts the entire mixing system at the same time to mix the sludge and the chemical liquid to achieve full flocculation and achieve After the liquid level line, the main body of the screw stack starts to work. The concentrated sludge continues to move forward with the rotation of the screw shaft. Driven by the continuous operation of the screw push shaft, the water in the sludge is squeezed out and the filter cake contains solids. The amount continues to increase, and finally the continuous dehydration of sludge is achieved.
The main body of the stacked snail is one or several groups of filtering units composed of a spiral pushing shaft, multiple fixed rings and multiple swimming rings. Each group of filtering units is divided into two parts: a concentration section and a dehydration section. The sewage from the concentration section is From the inlet to the mud cake outlet of the dehydration section, the pitch of the spiral shaft gradually becomes smaller, and the gap between the fixed ring and the moving ring also gradually becomes smaller. When the spiral shaft rotates, the multiple solid and active stacks move relative to each other. Under the action of gravity, water is filtered out from the gaps between the relatively moving stacks, achieving rapid concentration. The concentrated sludge continues to move forward along the mud as the spiral shaft rotates. In the direction of the cake outlet, the pitch of the spiral shaft gradually becomes smaller, and the gap between the rings also gradually becomes smaller. The volume of the spiral cavity continues to shrink. Under the action of the back pressure plate at the outlet, the internal pressure gradually increases, and the spiral pushes the shaft in turn. Driven by continuous operation, the water in the sludge is extruded and discharged, and the solid content of the filter cake continues to increase, ultimately achieving continuous dehydration of the sludge. The fixed ring and moving ring in the main body are made of special stainless steel and have been specially treated with high wear resistance and corrosion resistance to ensure service life.
In general, the stacked screw sludge dewatering machine uses the screw pressing principle to realize the strong squeezing force generated by the continuous advancement of the screw shaft and the tiny gap between the swimming ring and the fixed ring. A new type of solid-liquid separation equipment for sludge dehydration.
