A kind of centrifugal equipment and centrifugal method

Abstract

The invention discloses a centrifugal device and a centrifugal method, comprising a main drive device for providing a power source, a mold for providing a centrifugal working cavity, and a magnetic bearing seat, a first centering seat and a second centering seat , the mold is arranged on the magnetic bearing seat and the mold body of the mold is provided with a permanent magnet ring corresponding to the magnetic bearing seat, and one end of the mold is connected with the output shaft of the main drive device through the first centering seat, so The other end of the mold is connected with the second centering seat. The centrifugal equipment adopts the magnetic levitation centrifugal method, the mold body is provided with a permanent magnet ring, and the mold support position is a magnetic bearing structure. Compared with the traditional ball bearing, sliding bearing and oil film bearing, the magnetic bearing has no mechanical contact, so it has less mechanical wear and tear. , Low energy consumption, low noise, long life, no lubrication, no oil pollution.

Description

technical field [0001] The present 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 from liquid and solid particles or a mixture of liquid and liquid. It is widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding. For the centrifugal process of pipe pile products, in the existing design, the centrifuge is driven by a motor, and the rotational speed of the pipe mold is adjusted by the deceleration and frequency conversion speed control device to realize the centrifugation of the pipe mold at various speeds (different products have different centrifugal Process parameters), in which the centrifuge equipment has a parallel shaft structure, a conventional bearing is installed on the parallel shaft, the bearing seat is connected with the base through bolts, a support wheel structure is installed ...

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
