A centrifugal device for the production of modified polyamide resin

Abstract

The invention discloses a centrifugal device for modified polyamide resin production, which includes a machine base, and the top of the machine base is fixedly connected with a first storage bin, a centrifugal device, an air storage tank, a feeding device and a second feeding device in order from left to right. Two storage bins; the upper side of the centrifugal device is fixedly connected with a feeding pipe, and the bottom of the centrifugal device is rotatably connected with a first motor; a discharge device is arranged between the first storage bin and the centrifugal device. The left and right ends of the discharge device are respectively fixedly connected with the right side of the first storage bin and the lower side of the centrifugal device. The advantage of the present invention is that the pore size of the filter screen can be adjusted, and it is easy to be blocked by the separator; the present invention does not change the direction of the swirl solution by setting the spiral cleaning ring, and does not need to stop the present invention to remove the sticky material inside the first filter screen. Knot.

Description

technical field [0001] The invention relates to the field of resin preparation, in particular to a centrifugal device for producing modified polyamide resin. Background technique [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 regu...

[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
