screw type granulated substance water splitter may take each kind of sand collector supplementary equipment, uses in separating in the sandy sewage the granulated substance and other each kind of proportion big granulated solid matter. The sandy sewage from the cone-shape vessel upper extreme tangential enters, forms the turbulent flow in the vessel, in the gravity and under the centrifugal force function, the sand grains precipitates fast to the vessel base, pushes by the revolving screw blade to the upper extreme platoon granulated substance mouth elimination. Because uses specially enters the square water pitcher type to create the turbulent flow, makes the granulated substance the settling rate to speed up greatly, compares with the ordinary shape’s granulated substance water separator, the granulated substance settling rate is quicker, the granulated substance water separates the effect to be higher, through the experiment, is bigger than 0.2mm to the diameter the sand grains to separate the effect to reach as high as 98%.

After this product synthesized the domestic and foreign this type product service condition, improves the design, solved the lining strip replacement to be inconvenient and the screw axial location not adjustable flaw, its characteristic was as follows:
 1、The separation efficiency may reach 96%-98%,separable separating out particle size≥0.2mm pellet;
 2、 Uses the non-axis screw, the anhydrous middle bearing, maintains conveniently;
 3、The structure is compact, the weight is light;
 4、The new transmission device, its key produces—The reduction gear installs the type for the advanced axis, does not use the shaft coupling, installs conveniently to;
 5、The lining strip is the rapid installation type, is advantageous for the replacement;
 6、Screw axial location adjustable, is advantageous adjusts its rear part and the box wall’s safety gap.
