Description
Technical field
The utility model relates to a kind of sinter mixture operation technique field, particularly a kind of environmental protection, high precision unslaked lime continuous dosing of very, Digestive tract.
Background technology
In raw materials for sintering, add unslaked lime as the sintering basic solvent, can improve the balling-up property of compound, strengthen and granulate, improve the preheating temperature of compound, increase bed permeability.At present, often adopt unslaked lime directly down to add technologies such as water digestion automatically through digestive organ to mixing fetch water on the belt digestion and unslaked lime.All there is defective in these technologies:
1, unslaked lime is directly down to mixing the digestion process of fetching water on the belt: this process system is made up of feeding system, storage hopper, feeding machine, helix balance, belt etc., unslaked lime directly down to belt, the digestion of in the mixing belt, fetching water then.Though alleviated the difficult problem that burnt lime digester and pipeline of dust collector often block like this, cause on-the-spot dust big, quicklime slaking insufficient with mixture moisture fluctuation, problem such as fuel consumption is big, and board efficient is low;
2, helix balance is joined digestive organ and added the water digestion process automatically: this process system is made up of feeding system, storage hopper, feeding machine, helix balance, digestive organ, belt etc.; Adopt helix balance to join digestive organ and add the water digestion process automatically; Quicklime slaking is abundant; Reduce fuel consumption, improved board efficient.But the use certain hour, burnt lime digester and pipeline of dust collector just often block, and influence is produced.Adopt helix balance in addition, can not satisfy SINTERING PRODUCTION unslaked lime high precision ratio requirement;
3, weighing belt is joined digestive organ and added the water digestion process automatically: this process system is by feeding system, the storage hopper that is connected of feeding system, the gate that is connected with storage hopper, charge level detector, the feeding machine that is connected of gate, the weighing belt that is connected of feeding machine, the burnt lime digester that is connected of weighing belt therewith therewith therewith therewith; Be arranged on the sprinkling system on the burnt lime digester; The sintered mix belt conveyor; Relevant automatic control device is formed, and adopts weighing belt to join digestive organ and adds the water digestion process automatically, has improved the digestion degree of unslaked lime effectively; Reduce fuel consumption, improved board efficient.But, unslaked lime can give off a large amount of hot steams and dust because adding when water digests; Serious pollution is caused at the scene, and part steel mill uses wet dedusting now, utilizes nature negative pressure emission steam and dust; Its weak point is adhesion and the wall built-up that wind-collecting cover and tube wall have slurry; Exhaust duct is blocked easily and causes whole plant normally to move, and can not satisfy environmental requirement, and influence is produced.
Because being storage hopper from feeding system, the feed-type of existing installation directly is given to quantitative outputting material device in addition through gate; Can not accomplish hermetically sealedly, satisfy environmental requirement in the time of can not guaranteeing the continuous and quantitative convey materials even combine with the fly-ash separator dedusting.In addition, when feeding machine is supplied with the weighing belt material, run material sometimes, following funnel duration of service also possibly fallen down when long and hurted sb.'s feelings.
Above-mentioned feeding device environmental pollution is very serious.
Summary of the invention
The purpose of the utility model is to provide a kind of environmental protection, high precision unslaked lime continuous dosing of very, Digestive tract of high precision proportioning needs can satisfy continuous-feeding the time; Make quicklime slaking abundant; Improve the balling-up property of sinter mixture, strengthen and granulate, reduce fuel consumption; Improve board efficient, satisfy environmental requirement.
