Implementation method of improving dewatering efficiency of horizontal spiral centrifuge

In the process of using horizontal spiral centrifuge, the dewatering efficiency of the centrifuge is slow. The specific performance is as follows: with the increase of solid materials in the drum, the dewatering time of the centrifuge is prolonged, and the dehydration is not dry. This phenomenon is universal.

In order to improve the dewatering efficiency of the horizontal spiral centrifuge, the rotating speed of the centrifuge drum can be increased within the safe allowable range, and the material has no corrosion or small corrosivity; at the same time, the filtering area in the centrifuge drum can also be increased.

The specific implementation method is to increase the lining net to keep a small gap between the filter bag and the rotating drum of the horizontal spiral centrifuge, so as to improve the water permeability; to increase the cross-sectional area, such as adding V-shaped filter baffle. Of course, a small number of multiple dewatering methods, reducing the amount of filtering materials per centrifuge dewatering, more, less discharge method can also improve the supporting efficiency of horizontal spiral centrifuge.

If the material is sticky, wash it within the process limit. In order to increase the particle size of solid materials, in the case of constant process, if you want to increase the concern rate, you can consider adding, such as flocculant. During the operation of the horizontal spiral centrifuge, the solid content of the desalting cake and the solid content of the supernatant are changed by adjusting the rotating speed of the drum, the dry solid load, the type of flocculant, the concentration of the flocculant, the dosage and position of the flocculant, the thickness of the liquid annular layer, and the velocity difference curve.

Through the actual operation, we found that among the above factors, the setting of liquid annular layer thickness and the adjustment of speed difference are very important to the dewatering effect of centrifuge sludge.

In centrifuge, it is necessary to be familiar with and understand the specific type of horizontal spiral centrifuge, because it is not only website products and keywords, but also more common and commonly used types of centrifuge. Therefore, the purpose of familiarity and understanding of this kind of centrifuge is to correctly operate and use, and then, to obtain good use effect And it has good economic benefits in the use of the products.

The influence factors of working temperature of the bearing of horizontal screw separator generally include the following factors: whether the centrifuge itself is running at overspeed or overload, and whether the amount of lubricating grease is too much or too little. In addition, whether the bearing is worn or not will also affect its working temperature.
