A car-type continuous iron-making water slag separation and environmental protection device

Abstract

The invention discloses a car-type continuous ironmaking water slag separation environmental protection device, which includes a motor drive device, a loading trolley, a tail sprocket, a head sprocket, a reducer, a hydraulic pump station and a third connecting pipe. The left side of the sprocket is provided with a tail sprocket, the head sprocket and the tail sprocket are at the same height, and the tail sprocket and the head sprocket are connected by a running chain; the left side of the tail sprocket is provided with a tail hydraulic pressure Tensioning device, the left side of the tail hydraulic tensioning device is provided with a hydraulic pump station, the hydraulic pump station and the tail hydraulic tensioning device are connected through a first connecting pipe, and the upper right side of the first connecting pipe is connected with a second connecting pipe . The present invention is provided with a water permeable hole on the loading trolley, and the water in the water slag will be separated out during the rising process of the loading trolley, so the slag-water separation process is short, the energy storage effect is good, and the recovery and utilization of waste heat are convenient; in addition, in There is a filter screen inside the loading trolley, so that the water quality after separation of slag and water 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.
