Centrifugal equipment and centrifugal method

Abstract

The invention discloses centrifugal equipment and a centrifugal method. The centrifugal equipment comprises a main driving device used for providing a power source and a mold used for providing a centrifugal working containing cavity, and further comprises a magnetic bearing block, a first centering block and a second centering block, wherein the mold is arranged on the magnetic bearing block, a permanent magnet ring corresponding to the magnetic bearing block is arranged on a mold body of the mold, one end of the mold is connected to an output shaft of the main driving device through the first centering block, and the other end of the mold is connected to the second centering block. The centrifugal equipment adopts a magnetic suspension centrifugal mode, the permanent magnet ring is arranged on the mold body, a magnetic bearing structure is located at the mold supporting position, and compared with a traditional ball bearing, a sliding bearing and an oil film bearing, the magnetic bearing has the characteristics of being small in mechanical abrasion, low in energy consumption, small in noise, long in service life, free of lubrication and free of oil pollution due to the fact that mechanical contact does not exist.

Description

technical field [0001] The invention relates to a centrifugal device and a centrifugal method. Background technique [0002] A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. It is widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding and other departments. For the centrifugal process of pipe pile products, in the existing design, the centrifuge is driven by a motor, and the speed of the pipe mold is adjusted through the deceleration and frequency conversion speed regulating device, so as to realize the centrifugation of the pipe mold at various speeds (different products have different centrifugal Process parameters), wherein, the centrifuge equipment has a parallel shaft structure, the parallel shaft is equipped with conventional bearings, the bearing seat is connected to the base through bolts, the support wheel structu...

AI Technical Summary

Problems solved by technology

[0004] 1) The centrifugation process of concrete products is the process of solid-liquid separation. The uneven distribution of solid and liquid during centrifugation will lead to severe vibration of the pipe mold, and the low precision of equipment processing and installation will also aggravate the vibration of the pipe mold. The hard contact between the mold and the support wheel will lead to a low service life of the support wheel when the mold is centrifugal. In order to improve this situation, it is often necessary to continuously improve the performance of the support wheel, shaft and other accessories, which will greatly increase the manufacturing capacity of the equipment. Cost and manufacturing difficulty. There are many finished parts of related accessories, which will also be affected by periodic impact. The service life of the accessories is low, the maintenance cost is high, the maintenance frequency is high and the production efficiency is affected;

[0005] 2) The centrifuge adopts multi-stage transmission, which has low transmission efficiency, high equipment energy consumption, complex equipment structure and high maintenance difficulty;

[0006] 3) Due to the rolling hard contact between the mold and the support wheel, the centrifuge makes a lot of noise when it is working, resulting in strong noise pollution
