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.
Introduction to the main structure of the stacked screw sludge dehydrator: one of the spiral push shaft
The spiral shaft is composed of a shaft and a spiral blade, and the shaft is welded by a shaft, a shaft and a hollow shaft.
Assembly welding is to first weld the shaft and the hollow shaft, and then perform rough turning after welding to ensure the coaxiality of the shafts at both ends, and then the spiral blades and the shaft are welded by full welding, thereby reducing It reduces the pressure loss during the sludge dewatering process and ensures the working strength of the spiral blades. It can be seen from the working conditions of the spiral sludge dewatering machine that the outer circle of the spiral shaft blades is in direct contact with the swimming ring to generate friction, and the blade surface is always in contact with the sludge, causing some wear and tear. For this reason, our company uses a treatment process to first The outer circle of the spiral blade is cladded with hard material, and the cladding is thicker than the thickness. Then the entire shaft surface is thermally sprayed, and finally the outer circle of the spiral blade is ground to ensure the smoothness of the outer circle and reduce the play of the spiral shaft. Friction between rings. The shafts at both ends are precision turned to ensure the coaxiality and surface smoothness of the two shafts and reduce the friction between the spiral shaft and the nylon bushing.
The particles of hard materials are heated to a molten state or a highly plastic state under the action of a heat source. Under the thrust of an external gas or the flame itself, they are atomized and sprayed towards the surface of the substrate at high speed. The particles of the coating material are in contact with the substrate. Violent collision occurs and deforms, flattens and deposits on the surface of the substrate. At the same time, it is rapidly cooled and solidified rapidly. In this way, the particles are deposited in layers and accumulated into a coating. The surface hardness of the material after surfacing and spraying can reach up to 100%, which is very hard and wear-resistant.
The snail stacking sludge dewatering machine is composed of the snail stacking main 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.
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.
