What are the debugging elements of a Horizontal spiral discharge centrifuge
Before the horizontal spiral discharge centrifuge is put into use, it must first check and debug the parameters. The first thing to be debugged is the separation factor of the equipment, that is, the drum speed of the Horizontal spiral discharge centrifuge. The solid-liquid density difference of the suspension is large, the sedimentation speed is fast, and the separation effect is good. The viscosity of the liquid is small, the sedimentation speed is fast, and the separation effect is better.
It can be seen that the size of the solid particles has a great influence on the separation effect of the horizontal spiral discharge centrifuge. The large particles are simply settled and separated, and the small particles are not easy to settling and separating. That is, the disposal volume and disposal of the centrifuge are proportional to the size of the particles. The viscosity of the liquid is inversely proportional.
For different materials and different working conditions, the separation factor used is not the same. If the solid particles of the material are small, the solid-liquid density difference is small, the viscosity of the liquid is large, and the separation factor is as large as possible. If the solid particles of the material are large, the solid-liquid density difference is large, the liquid viscosity is small, and the separation factor can be smaller. If the flocculant is added during solid-liquid separation to form a cluster, the separation factor can be lower.
Secondly, the differential rotation speed between the screw and the drum of the horizontal spiral discharge centrifuge must be determined. If other operating conditions are not changed, if the differential speed is smaller, the spiral conveying speed will decrease and the solid phase will stay in the dehydration zone. It is added all the time, and a solid phase with a lower moisture content can be obtained. As the speed of screw transportation decreases, its carrying capacity decreases, and the liquid phase clarity decreases, and vice versa.
Finally, the depth of the liquid pool in the Horizontal spiral discharge centrifuge must be adjusted. By adjusting the height of the overflow plate, different depths of the liquid pool can be obtained, so that the length of the dehydration zone and the settlement zone in the drum can be changed, thereby changing the centrifuge.
