Washing method and device matched with continuous automatic material pushing type centrifugal dewaterer

Abstract

The invention provides a washing method and device matched with a continuous automatic material pushing type centrifugal dewaterer. A newly designed short pipe slit type spray head is utilized to replace a multi-hole type spray head of the prior art, and therefore washing water forms laminated water flow under pressure through slits in the short pipe spray head; the formed laminated water flow is utilized to wash materials in the continuous automatic material pushing dewaterer. The short pipe slit type spray head is a section of a short pipe with a thick wall, a section of the slits are formed in the short pipe in the axial direction, the washing water can form the stable and tidy laminated water flow under pressure when passing through the slits, the washing water inlet end of the short pipe slit type spray head is installed on a end cover door of the continuous automatic material pushing dewaterer and communicated with a washing water supplying pipe on the outer side of the centrifugal dewaterer. The washing method and device have the advantages of being good in washing effect, water-saving and energy-saving, and are suitable for dewatering sizing agents and washing the materials at the same time.

Description

technical field [0001] A method and device for washing liquid-solid mixed materials while continuously dehydrating, specifically a method and device for washing materials matched with a continuous automatic pusher type centrifugal dehydrator. Background technique [0002] When the existing continuous centrifugal dehydrator dehydrates the mixed material containing solid particles, the water-containing material rotates with the drum at high speed in the continuous centrifugal dehydrator, and the material is dehydrated under the action of high-speed rotating centrifugal force, and at the same time, it is dehydrated under the push of the screw pusher. The outlet of the dehydrator moves, and the dehydrated solid particles reach the outlet of the dehydrator and leave the dehydrator. Generally, the material will contain some impurities after direct dehydration. In order to make the dehydrated solid particles cleaner, a washing water nozzle is installed in the dehydrator to spray wa...

AI Technical Summary

Problems solved by technology

Because the water droplets produced by this porous nozzle are random and irregular, some parts of the materials in the dehydrator may be washed many times, while some parts are washed very few times, and some parts are not even washed. In this way, the entire material layer cannot be washed evenly, which will inevitably cause the overall washing effect to be unsatisfactory, which will directly affect the quality of the final solid material product, or increase the amount of washing water in order to achieve the ideal washing effect, which will undoubtedly cause Water waste and increased energy consumption
