Metal smelting blast furnace slag bottom filtering method filtering system

Abstract

The invention discloses a metal smelting blast furnace slag bottom filtering method filtering system, which comprises a pool body, wherein a filtering mechanism is arranged in the pool body, the filtering mechanism comprises two first partition plates, the interior of the pool body is equally divided into three filtering areas by the two first partition plates, U-shaped pieces are fixedly arranged at the tops of the two sides of the pool body, and the U-shaped pieces are right opposite to the first filtering areas; a U-shaped sliding groove is formed in the U-shaped piece. By arranging the first filtering layer, the second filtering layer and the third filtering layer of the filtering mechanism, water granulated slag can be subjected to multi-stage filtering, and the filtered slag particles are divided into three different sizes, so that the slag particles with different sizes can be recycled; in addition, the stirring mechanism operates along with rotation of the first rotating shaft, and under the action of the stirring mechanism, the materials inside first filtering area and the second filtering area can be stirred, so that the situation that small slag particles are blocked by large slag particles at the bottom and cannot fall off along with continuous accumulation of the slag particles is prevented, and the practicability is improved.

Description

technical field [0001] The invention relates to the field of metal smelting equipment, in particular to a metal smelting blast furnace slag bottom filtration system. Background technique [0002] A high-efficiency filtration system for blast furnace slag bottom filtration method disclosed in Chinese invention CN110947209A, the disclosed content is "including a filter pool, a modular filter layer and a drainage structure are arranged at the bottom of the filter pool, and the modular filter layer contains multiple Filtration module, the drainage structure includes a horizontal drainage main pipe and a drainage branch pipe, the interior of the drainage branch pipe is connected with the interior of the drainage main pipe, and the side wall of the drainage branch pipe is provided with a water-permeable through hole. The high-efficiency filtration system of the blast furnace slag bottom filtration method contains a module When the filter medium in the modular filter layer has hard...

AI Technical Summary

Problems solved by technology

[0003] However, there are still deficiencies in the process of use. When the device works every time, the initial injection of water slag into the filter tank will impact the filter layer in the filter tank, and the long-term use of the device will reduce the service life of the filter layer, and different sizes The slag particles are all left on the filter layer, which is not convenient for the recycling of slag particles
