The adaptability of the centrifuge from the specifications of the decanter centrifuge

Apr 11, 2019

Centrifuge separators come in a wide variety of equipment, and various types of decanter centrifuges are dazzling. Thanks to the centrifuge industry, the important parameters of the centrifuge are defined as a uniform national standard, from a simple centrifuge model specification code. It is possible to read most of the important parameter information of the centrifuge separator to provide favorable conditions for comparison on the paper for the selection of the centrifuge. Of course, the model code of the centrifuge not only provides a comparison reference for the parameters on the selection. It also provides the targeted adjustment of the centrifuge in adapting to the development of the industry. Let's take the decanter centrifuge as an example to talk about the improvement of the centrifuge in the solid-liquid separation industry.


Diameter of drum modified by decanter centrifuge:


The drum diameter is a very important parameter of the centrifuge. The centrifuge code LW450X2000 is analyzed. In the centrifuge model code, the centrifuge drum diameter parameter 450 and the centrifuge length 2000 are the parameters that mainly characterize the performance of the centrifuge. . In production, the larger the diameter of the horizontal screw centrifuge, the larger the settlement area in the solid-liquid separation process. The stronger the processing capacity, such as the design of a series of centrifuge drums according to the actual processing needs of different industries. Diameter, only the diameter of the horizontal screw centrifuge drum has 250, 300, 355, 400, 450, 500, 530, 580, 650 and other parameters, more suitable for the precise positioning of the centrifuge industry.


 Rotating drum length modified by decanter centrifuge:


There is a very real problem that the diameter of the drum of the centrifuge cannot be increased infinitely due to the limitation of materials and technology. In order to enhance the separation ability, there is a design trend of increasing the aspect ratio. The diameter of the current centrifuge drum In the range of 200~1000mm, as the length of the drum of the centrifuge increases, the length-to-diameter ratio of the drum of the decanter centrifuge gradually increases. The time of the material in the drum is also equal to the phase change. The separation performance of the equipment, the development of the horizontal screw centrifuge has been developed to 3 to 4 times the aspect ratio and the trend of targeted increase according to the need, high speed and high aspect ratio is one of the trends of the development of centrifuges.


The pushing mechanism of the horizontal screw centrifuge:


The pushing mechanism of the centrifuge is an important component of the centrifuge, and it is responsible for the important task of slag removal and slag removal in the separation process. The important problem in the design and manufacture of the centrifuge is to solve the problem of smooth discharge of the material, and pass the design and manufacture. Strictly define the adjacent pitch and the half cone angle of the drum, which can effectively serve the slag blocking problem and make the slagging smooth. With the expansion of the horizontal screw centrifuge market and the targeted enhancement of the centrifuge to the industry, the development of the centrifuge later The trend will be more and more adaptable in a smaller and smaller range.
