Abstract

The invention relates to devices for the separation of mineral grains in a liquid by the rate of their deposition and mb. used in industrial construction materials, chemical, petrochemical and other industries. The purpose of the invention is to increase productivity. The classifier includes a metering tank 1. a receiving chamber 2 and a classification chamber 3 (K) connected with elastic nozzles (П) - hose pumps 4 with П 5 and П 6 unloading small product, and a vibration pump 9 installed in front of the metering tank 1. In the lower part of K 3 there is a sector shutter 7 for supplying a large product to the P V discharge. The pulsating flow of the initial mixture by the vibrating pump 9 is fed into the metering tank 1 and through K 2 enters the K 3. A large product is deposited in the cell of the sector gate 7 and is transported to the warehouse as the cells are filled. The small product according to claim 4-6 is diverted to dehydration. The separation boundary of the products is controlled by the elastic characteristics of the P 4 and the amplitude and frequency of the pulsating flow of the initial mixture. 1 il.

Description

The invention relates to devices for separating mineral grains in a liquid according to their sedimentation rates and can be used in the building materials industry, chemical, petrochemical, hydrometallurgical and other industries.

The purpose of the invention is to improve the performance of the classifier.

The drawing shows a vertical hydraulic classifier, a general view.

The classifier contains the metering tank 1, the receiving 2 and the classification 3 chambers, the latter with the help of elastic nozzles - hose pumps 4 are connected to the nozzles 5 and 6 of the small product unloading 5. In the lower part of the chamber 3, a sector shutter 7 is placed for supplying a large product to the unloading pipe 8 of a large product. The source material is fed to

ten

With the aid of hose pumps 4, it is discharged through pipes 5 and 6 and transported for dehydration. The large product, as the cells of the sector gate 7 are filled, is transported to the warehouse. The separation boundary of the slurry is controlled by the elastic characteristics of the hose pumps 4, which are driven by the pulsating flow of the initial mixture. The boundary of separation is within 1-8 mm and is controlled by the elastic characteristics of the hose pumps, as well as the amplitude and frequency of the pulsating flow of the original mixture.
