Problems solved by technology

[0003] At present, conventional centrifuges are mainly horizontal screw discharge sedimentation centrifuges. Due to structural limitations, the differential transmission ratio of this centrifuge is not high, so one or more motors with higher power are often used to drive, so that The centrifuge vibrates greatly during operation, the main bearing of the centrifuge is easily damaged, and requires frequent maintenance. At the same time, the noise is relatively large during operation, generally greater than 85dB, and the water content in the separated solid is greater than 25%.

Abstract

The invention relates to the technical field of centrifuges, in particular to a spiral separation type vertical centrifuge, and discloses a vertical spiral liquid-solid centrifuge for realizing ultralow water content of solid products. The vertical spiral liquid-solid centrifuge comprises a shell, a feeding pipe, a main motor, an auxiliary motor, a differential mechanism, a spiral pusher and a rotary drum, wherein the spiral pusher is positioned in the rotary drum and comprises a middle shaft and a spiral blade, the spiral blade is fixedly connected with the middle shaft and adopts a hollow structure, and a plurality of holes are uniformly formed in the spiral blade in the circumferential direction of the spiral blade at intervals. The spiral pusher provided by the invention adopts the spiral blade with the hollow structure, so that liquid and solid of turbid liquid start to be separated before reaching the rotary drum, the separation efficiency and the separation quality of the centrifuge are improved, the separation efficiency of the centrifuge is improved by 10%-20%, and particles with the particle size not less than 0.2 micrometer can be recycled.

Description

technical field [0001] The invention relates to the technical field of centrifuges, in particular to a spiral separation type vertical centrifuge. Background technique [0002] The centrifuge uses the principle of different density and immiscible light, heavy liquid and solid phases in the mixed liquid to obtain different sedimentation velocities in the centrifugal force field, so as to achieve the purpose of separating layers or settling solid particles in the liquid. It is mainly used in chemical industry, mineral processing, petroleum, pharmaceutical, food and other industries, as well as sewage treatment with foul smell and other occasions that require sedimentation and separation of solid-containing suspensions. [0003] At present, conventional centrifuges are mainly horizontal screw discharge sedimentation centrifuges. Due to structural limitations, the differential transmission ratio of this centrifuge is not high, so one or more motors with higher power are often us...
