Centrifugal device for producing modified polyamide resin

Abstract

The invention discloses a centrifugal device for producing modified polyamide resin. The centrifugal device comprises a machine base, wherein a first material storage bin, a centrifugal device body, an air storage tank, a feeding device and a second storage bin are sequentially and fixedly connected to the top of the machine base from left to right; a discharging pipe is fixedly connected to the upper side of the centrifugal device body, and a first motor is rotationally connected to the bottom of the centrifugal device body; and a discharging device is arranged between the first storage bin and the centrifugal device, and the left end and the right end of the discharging device are fixedly connected with the right side of the first storage bin and the lower side of the centrifugal devicebody respectively. The centrifugal device has the advantages that the aperture size of a filter screen can be adjusted, and the filter screen can be easily blocked by separated objects; and the direction of a rotational flow solution is not changed by arranging a spiral cleaning ring, and an adhesive in a first filter screen is not required to be cleaned by the method.

Description

Technical field [0001] The invention relates to the field of resin preparation, and more specifically, to a centrifugal device for the production of modified polyamide resin. Background technique [0002] At present, the production process of modified polyamide resin requires multiple centrifugal separation of different products to finally obtain pure epoxy resin; the centrifugal separation device uses centrifugal force to separate the components in the mixture of liquid and solid particles or liquid and liquid Machinery; Centrifuge is mainly used to separate solid particles in suspension from liquid, or to separate two liquids with different densities but incompatible with each other in emulsion; the filter screen of the existing filter centrifuge is It is easy to be blocked during the separation process, which leads to a decrease in the subsequent separation effect; further, the existing centrifugal separator is to ensure timely cleaning of the adhesion on the filter screen by ...

Problems solved by technology

[0002] At present, in the production process of modified polyamide resin, different products need to be centrifuged several times to finally obtain pure epoxy resin; the centrifugal separation device uses centrifugal force to separate the components in the mixture of liquid and solid particles or liquid and liquid Machinery; the centrifuge is mainly used to separate the solid particles in the suspension from the liquid, or to separate two liquids with different densities and immiscible liquids in the emulsion; the filter screen of the existing filter centrifuge is It is easy to block during the separation process, resulting in a decline in the subsequent separation effect; further, in order to ensure that the adhesive on the filter screen is cleaned in time, the existing centrifuge is cleaned regularly by setting a scraper; the scraper cannot work when the centrifuge is working, so it cannot be continuous The separation efficiency is greatly reduced; further, when the scraper is vertically arranged in the centrifuge, the swirling direction of the liquid inside is changed; furthermore, the material to be separated cannot pass through the filter screen in time; the feeding device provided by the present invention can not only transport liquid It can also transport gas. When the centrifugal device does not work for a long time, an inert gas is introduced into it to prevent internal corrosion; the application number is 201280033635.0, which discloses an intermittent centrifugal separator with a scraper for scraping the product by setting a vertical The straight scraper changes the swirling direction of the internal liquid, so that the material to be separated cannot pass through the filter screen in time; the application number is 201820087479.0, a solid-liquid centrifugal separator, the pore size of the filter screen cannot be adjusted, and it is easy to clogged with septa
