Slag slime post-processing device and method thereof

Abstract

The invention relates to a post-treatment device and method for slag sludge. The post-processing device for slag sludge is installed at the output rear end of the sand washing machine that processes the slag that has been screened to a size below 8mm. It is connected to a device for controlling the water level difference and a powerful pump at the output rear end of the sand washing machine. And set a mud-water separation device connected to the outlet of the powerful pump with a pipeline, and a reservoir connected to the mud-water separation device with a pipeline, and have a drying bed, and a partition wall is set in the mud-water separation device to make the mud water The inside of the separation device is divided into a front part and a rear part. The post-processing method of the slag slime includes the following steps: conveying operation, mud-water separation operation, and continuous water storage operation. The invention can achieve the effect of complete recovery and reuse of the slag slime.

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 ...

Problems solved by technology

[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
