Description
Technical field
The present invention relates to zinc hydrometallurgy industry medicament batching feeding technique field, is a kind of dry material automation charging system specifically.
Background technology
Along with the development of world economy, country is also more and more higher to the requirement of energy-saving and emission-reduction, and industry energy conservation reduces discharging an important and pressing task that has become the current Chinese economy social development, and the energy-saving and emission-reduction of hydrometallurgy industry are also extremely urgent.It is to leach high temperature peracid---the important step of jarosite deferrization process that the zinc hydrometallurgy medicament adds, concerning the control of procedure technology technical index whether accurately, heavy alum supernatant quality quality, middle supernatant rate height and product design up-to-standard important step whether.At present, the feed way of zinc hydrometallurgy industry medicament adopts hand stock always, and what good technology is the same industry do not have use.The leaching system is very big to the addition demand of manganese powder and ammonium bicarbonate, adopts manual type reinforced, mainly has following drawback:
1, worker's labour intensity is very big.By the production demand, per tour need add 4～8 tons of manganese powders, 5～10 tons of carbon ammoniums, and this work capacity is finished by two workers in medicament post, labour intensity is very big;
2, hand stock is difficult to guarantee that even, continuous, the quantification of medicament add system Fe
3+And Fe
2+Fluctuation range is very big, causes heavy alum supernatant muddiness, and the solid content height directly soaks supernatant rate and middle supernatant quality in the influence.Specifically, if oxidizer (manganese powder) adds off and on, because the big (190～200m of system's driving flow
3/ h), make Fe
2+In time be not oxidized into Fe
3+Hydrolysis is removed and is entered middle supernatant, and supernatant runs iron in causing, and middle supernatant is off quality; If heavy alum agent (carbon ammonium) adds off and on, then can cause heavy alum supernatant iron content to exceed standard, oxidation liquid iron content is too high, causes neutral leaching operation hydrolysis iron too much, and ore pulp viscosity raises, the sedimentation difficulty, middle supernatant rate is low, has a strong impact on production capacity;
3, owing to hand stock, feeding quantity can not reach the quantification accuracy control, makes the excessive system that enters of medicament, causes system to produce mal.As the Mn of system
2+High when the highest (reach 25g/l) directly causes the reduction of Faradaic current efficient, and production capacity reduces; The carbon ammonium is excessive when adding, and system contains NH
4 +Too high, causing the crystallization of process pipeline waste water storage tank, many crystallization cleaning cycle shortens and fast, has not only increased worker's labour intensity, and cause producing can not be normal;
4, the dust environmental pollution that flies upward and worker's physical and mental health worked the mischief;
5, because hand stock can not be accomplished the quantified controlling of medicament addition, cause a large amount of wastes of medicament.
Summary of the invention
Technical matters to be solved by this invention is to overcome existing hand stock mode to make medicament add inaccuracy, inhomogeneous, discontinuous, to producing the big problem of influence, thereby provide a kind of by utilizing belted electronic balance auto feed technology, make the zinc hydrometallurgy with medicament add accurate, quantification, continuous, reach stabilizing control system Fe
3+And Fe
2+, make heavy alum supernatant limpid, solid content is low, thereby soaks a kind of dry material automation charging system of supernatant rate and middle supernatant quality in guaranteeing.
Technical matters of the present invention adopts following technical proposals to solve:
A kind of dry material automation charging system, comprise raw materials bucket, electronic belt scale, storage bin(hopper), slat conveyer, pulp groove and conveyor screw, described loading hopper is located at the slat conveyer lower end, a storage bin(hopper) is established in described slat conveyer upper end, the electricity gate that surges is established in the storage bin(hopper) lower end, the electricity hydraulic brake student holds the connection star feeder, the star feeder lower end is provided with electronic belt scale, a conveyor screw is established in the electronic belt scale lower end, the conveyor screw lower end is provided with raw material pulp groove, and pulp groove upper end is provided with mixing device; The actuating device of described slat conveyer is located at the slat conveyer upper end.
Described loading hopper one side is equipped with bagroom.
Described bagroom connects a side dust collection cover by dust collection pipe, and a star feeder is established in the bagroom lower end, and star feeder is communicated with slat conveyer; Establish one in the described side dust collection cover and survey dust concentration infrared probe when reinforced, infrared probe links to each other with dust collecting fan on being located at bagroom.
Described electricity belt conveyer scale link to each other with the field control conv with the Long-distance Control treater, realize long-range and field control.
Dust boot is equipped with in the junction of described belted electronic balance and conveyor screw.
The present invention has following characteristics:
1, by utilizing belted electronic balance auto feed technology, make zinc hydrometallurgy add accurate, quantification, continuous with manganese powder, reach stabilizing control system Fe
3+And Fe
2+, make heavy alum supernatant limpid, solid content is low, thereby soaks supernatant rate and middle supernatant quality in guaranteeing, stops because of oxidizer (manganese powder) reinforcedly off and on, and supernatant runs iron in causing, and the phenomenon that middle supernatant is off quality has been guaranteed the qualification rate 100% of product design.
2, quantitative, accurate, the adding continuously of carbon ammonium make heavy alum supernatant iron content up to standard, have stablized the supernatant rate of neutral leaching operation, have guaranteed finishing of system's production capacity.
3, this system adopts full-automatic control, has reduced worker's labour intensity.
4, effectively reduce the Mn of system
2+Content has improved the current efficiency of electrolysis.
5, avoid the excessive adding of medicament, saved cost.
6, by transforming, stop dust to the pollution of environment with to the able-bodied harm of worker.
Economic benefit:
Manganese powder and carbon ammonium consumption before and after contrast is transformed down according to market price measuring and calculating with technological condition:
Annual 582 tons of the manganese powders of saving are saved ten thousand yuan of cost 582 * 1700=99
Annual 1263 tons of the carbon ammoniums of saving are saved ten thousand yuan of cost 1236 * 630=77.87
The annual total cost of saving: 176.87 ten thousand yuan
The present invention has not only solved and has adopted the hand stock mode to make medicament add inaccuracy, inhomogeneous, discontinuous in the original design, to producing the big problem of influence, and annual cost-saved 176.87 ten thousand yuan, eliminate manganese powder and carbon ammonium simultaneously to the pollution of environment and to the harm that the person causes, had good economic value and industry promotional value.Simultaneously, the present invention also is applicable to the accurate automatic blending feeding technique of the dry material field of industries such as chemical industry that Large Scale and Continuous produces, food, pharmacy except that satisfying zinc hydrometallurgy industry medicament that Large Scale and Continuous produces continuously, automatically, accurately the proportioning feeding technique requires.
