Vehicle type continuous ironmaking water-slag separation environment-friendly device

Abstract

The invention discloses a vehicle type continuous ironmaking water-slag separation environment-friendly device. The device comprises a motor driving device, a loading trolley, a tail chain wheel, a head chain wheel, a speed reducer, a hydraulic pump station and a third connecting pipe, wherein the tail chain wheel is arranged on the left side of the head chain wheel, the head chain wheel and the tail chain wheel are located at the same height, and the tail chain wheel is connected with the head chain wheel through a running chain; a tail hydraulic tensioning device is arranged on the left sideof the tail chain wheel, the hydraulic pump station is arranged on the left side of the tail hydraulic tensioning device, the hydraulic pump station is connected with the tail hydraulic tensioning device through a first connecting pipe, and a second connecting pipe is connected to the upper portion of the right side of the first connecting pipe. A loading trolley is provided with water permeableholes, and water in water slag can be separated out in the ascending process of the loading trolley, so that the slag-water separation process is short, the energy storage effect is good, and waste heat can be conveniently recycled; in addition, a filter screen is arranged in the loading trolley, so that the water quality after slag-water separation is better.

Description

technical field [0001] The invention relates to the environmental protection field of ironmaking slag treatment, in particular to a car-type continuous ironmaking slag separation and environmental protection device. Background technique [0002] Water slag is a by-product of blast furnace ironmaking. After processing, it is mainly used to make building materials. In the process of blast furnace production, after smelting various raw materials and fuels into the furnace, in addition to obtaining molten iron (steelmaking pig iron or foundry pig iron) and by-product blast furnace gas, the gangue in the iron ore and the ash in the fuel are fused with the flux. Liquid slag is formed, and its general temperature is 1450-1550°C, which is discharged from the slag port and iron port at regular intervals. Usually, the molten slag discharged from the slag hole is called "upper slag", and the molten iron discharged from the iron hole is called "lower slag". The lower slag is often mixe...

Problems solved by technology

[0004] The traditional scum removal method is to install a filter screen at the water outlet, and manually operate the grab to clean the water slag. The main problem of this method is that the scum in the pool is not easy to grab. If the filter screen is not cleaned in time, it will easily lead to mesh blockage. death, which brings great hidden dangers to the subsequent water cycle process

At the same time, workers have to operate the grab bucket on site, which is labor-intensive and low-efficiency. Therefore, it is urgent to develop a new automatic slag cleaning device.
