Device and method for post treatment of slag mud

Abstract

The invention relates to a device and a method for post treatment of slag mud. The device for the post treatment of the slag mud is arranged at an output rear end of a sand washing machine screening slag with a size of less than 8mm; the output rear end of the sand washing machine is connected with water level difference-controlling equipment and a strong pump and provided with a mud-water separator connected with the output end of the strong pump through a pipeline, a water tank connected with the mud-water separator through a pipeline and a drying bed; and the mud-water separator is inside provided with a partition wall that divides the inside of the mud-water separator into a front part and a rear part. The method for processing the slag mud rear section comprises the following steps of: transportation operation, mud and water separation operation and water storage continuous operation. The device and the method can achieve the effect of completely recycling slag mud.

Description

technical field [0001] The present invention relates to a post-processing device and method for slag sludge, in particular to a water-washing post-processing device and method for steelmaking slag processing, which can avoid flying dust and prevent lime from affecting soil and groundwater sources. And it can be further refined, and the slag sludge post-processing device and method can be completely recovered and reused. Background technique [0002] A complete set of steelmaking slag post-processing technology can be divided into four-stage procedures, including steelmaking slag pretreatment procedure, steelmaking slag processing procedure, steelmaking slag curing procedure and residual steel finishing procedure, but in the slag postprocessing industry It is not necessary to have all four procedures, but to choose and choose according to their respective needs. Among them, the steelmaking slag processing procedure mainly involves crushing, magnetic separation, screening and ...

AI Technical Summary

Problems solved by technology

[0008] 1. High equipment cost: After the slag is dried, it will cause lime dust to fly and pollute the air. Therefore, in addition to the drying equipment, an additional pollution prevention equipment dust collector 56 must be installed, which greatly increases the equipment cost.

[0009] 2. Low operating efficiency: Since this treatment method must be completely dried to sort out the expected type of ingredients, the amount of feed should not be too much at one time during the drying process, otherwise it will cause the process to stagnate and block, and the Seriously affect work efficiency

[0010] 3. Air pollution: Even if the existing conventional treatment methods are equipped with pollution prevention and dust collection equipment, they can only reduce the fine dust in the air to the standard value, and cannot completely isolate the problem of flying dust

[0011] 4. High maintenance cost: In addition to the cost of the whole set of equipment, the cost of maintenance, maintenance, operation and consumption of pollution prevention equipment and drying equipment in the future is quite high, and its failure rate is high, which will increase a lot of maintenance costs

[0013] This shows that the above-mentioned existing slag slime processing device and method thereof obviously still have inconvenience and defects in product structure, manufacturing method and use, and need to be further improved urgently

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
