Description
Technical Field
The invention relates to a structure for comprehensively recycling lime slaking residues, and belongs to the technical field of lime slaking residue recycling.
Background
The traditional lime milk preparation mode in the alumina industry is to adopt an ash melting machine to mix water or mother liquor, washing liquor and the like to operate and melt ash to prepare lime milk, because the lime melting machine can discharge residues in the operation process due to the component and quality problems of lime, the residues can not be recycled and comprehensively utilized, the residues are all subjected to outer piling and then are transported into an ore yard to enter the front end of the production system flow, the red mud amount is increased, the stable operation of the system and the sedimentation and washing consumption are increased, a large amount of carbonate is also promoted to enter the front end flow of the production system, the causticization of sodium carbonate in the system is inhibited to form the anti-causticization effect, partial useful component calcium oxide is carried in the residues in the discharging process, the waste of lime consumption is discarded, the residues are subjected to outer piling, powder dust flying ash is formed after weathering, the environmental protection management is influenced, and the waste of the outer piling management and the transportation labor force are also caused.
The lime powder is used for preparing the lime milk, so that the cost is high, and the market competition of enterprise production is not facilitated.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a structure for comprehensively recycling lime digestion residues, which can avoid the influence of the front end of the flow of the residues entering a production system on the production system, reduce the waste of lime consumption, avoid the influence of environmental protection treatment caused by the formation of powder flying dust due to the drying or weathering of part of components in the residues after the residues are piled outside due to external conditions, and simultaneously avoid the increase of labor force for the stockpiling management and transportation caused by the piling; the defects of the prior art can be overcome.
The technical scheme of the invention is as follows: a structure for comprehensively recycling lime slaking residues comprises an ash melting machine and an ash emulsion groove, wherein a residue outlet is formed in the ash melting machine, a crusher is arranged at the residue outlet, and the crusher is connected with the ash emulsion groove.
The feed opening of the crusher and the ash melting machine are both provided with hot water supply pipes, and the hot water supply main pipe is provided with a solid content index adjusting device.
A stirring device is arranged between the crusher and the lime milk tank, and a concentration detection device is arranged on the stirring device.
The ash melting machine is connected with the crusher, the crusher is connected with the stirring device, and the stirring device is connected with the ash emulsion tank through the transfer tank.
The screen mesh of the crusher is 5mm in aperture.
Compared with the prior art, the structure for comprehensively recycling the lime slaking residue has the following advantages:
(1) The method comprises the steps that a crusher is additionally arranged to crush residues, a slag discharge port of the ash melting machine is designed to be introduced into the crusher, the crusher is started to operate to crush the residues simultaneously in the ash melting machine ash crushing and ash emulsion preparing process, and the crushed lime residues are introduced into an ash emulsion groove to prepare the ash emulsion, so that the ash residues are prevented from being recycled in time to be comprehensively utilized after being stacked outside, transported into a mine storage yard and finally enter the front end of a production system flow again to cause influence on a production system; meanwhile, the consumption waste of lime milk preparation by lime and the formation of powder flying dust by residue outside the pile are avoided, and the increase of labor force for management and transportation caused by residue outside the pile is also avoided.
(2) Hot water supply pipes are arranged on a feed opening of the crusher and the ash melting machine, so that in the process of starting the crusher to operate and crush residues, a small part of water is led out from original hot water which is mixed with water by the ash melting machine to prepare ash emulsion and is used as dilution drainage washing water for crushing the residues, and the residues are prevented from being blocked at a screen after being crushed;
(3) Be equipped with sample detection granularity device between breaker and ash milk groove, add sample detection granularity device like this and can carry out first regulation granularity to the residue after the breakage, through the adjustment that contains index adjusting device admittedly, avoid influencing the quality of follow-up ash milk groove production ash milk, be favorable to further ensureing that production demand ash milk contains the index admittedly.
(4) The screen mesh aperture of the crusher is 5mm, the residue crushing test is carried out, a screen with the aperture of 5mm is selected as a screen, the granularity index is changed from 10-25mm of original particles to the granularity index larger than 5mm and not larger than 12 percent on the screen, and the granularity index of the residue meets the production requirement and is completely recycled to enter the production flow.
