Description
Technical field
The utility model belongs to chemical machinery field, and in particular to a kind of calcium oxide Digestive of nano-calcium carbonate production
System, belongs to the digestion workshop section during Production of Light Calcium Carbonate.
Background technology
There are the digestion step of calcium oxide, calcium oxide (quick lime) plus water input digestion machine in nano-calcium carbonate production process
In reacted, release amount of heat generation calcium hydroxide (milk of lime), by milk of lime be passed through carbon dioxide carbonization after generate carbon
Sour calcium.In the digestion step of calcium oxide, reaction can release substantial amounts of heat, and reaction process needs a large amount of cooling waters and stirring
Operation, existing reactor cause inconvenient for operation, low production efficiency and manual labor is big since structure setting is unreasonable
The shortcomings that, and reaction process is often more violent, stirring is not abundant enough, and the security of worker cannot ensure well, and
Serious steam contamination is produced in digestion process, and digester feed is uneven.
Most digestive system all can not achieve the continuous metaplasia integrally controlled due to above productive prospecting at this stage
Production, this, which has resulted in calcium oxide digestion step at this stage, becomes the restrictive factor restricted in nano-calcium carbonate production process, raw
The demand for producing digestion machine efficient, easy to operate, that security is good just seems very urgent.
Utility model content
The shortcomings that the utility model is exactly to solve nano-calcium carbonate production process digestion step and design proposition.
To achieve the above object, the utility model provides following technical solution：A kind of oxidation of nano-calcium carbonate production
Calcium digestive system, including material pond, bucket elevator, feed bin, digestion machine and stock tank composition, the calcium oxide of material pond storage by
Driving motor supplies power driving bucket elevator lifts material；Material is delivered to feed bin by the bucket elevator
It is interior, digested by hopper into digestion machine；The hopper top is arranged to the bore identical with feed bin, lower part in tapered,
And it is supported by stent；The digestion machine is supported by former and later two rolling rings, is arranged to that the high discharge end of feed end is low to incline
Rake angle；The digestion machine exit lower end is provided with stock tank, to store postdigestive product milk of lime.
Preferably, the lower part of the stent is provided with lifting base, can be adjusted according to the height of digestion machine inlet；
The nearly discharge port bottom of digestion machine is provided with outlet, for digesting the discharge of waste liquid in machine cleaning operation process.
Preferably, the electric rotating machine driving that the digestion machine is set by nearly feed inlet end carries out rotation digestion, digests machine
Angle of inclination can be adjusted by the rolling ring lifting unit of rolling ring lower part.
Compared with prior art, the beneficial effects of the utility model are：Mortar quality is good, and milk of lime is fine and smooth, and concentration is adjusted
It is convenient, reasonable process control lime milk concentration can be formulated as needed.Digestion machine makes lime slaking fast due to internal blender
Degree is accelerated, and digestibility improves.Lime slaking heat release is taken full advantage of, material is in fluidized state all the time in digestion machine, digestion
When heat loss it is small, digestion rate is very fast, and quick lime can digest completely at 15 minutes, since digestion temperature is high, in other works
The lime that cannot be digested under the conditions of skill can also be digested completely.Mechanization degree is high, and operation control is easy, and equipment is solid resistance to
With easy break-down, service life are not grown, the production especially suitable for precipitated calcium carbonate.Scarfing cinder is very convenient, and lime white is from digestion
Mechanical deslagging is utilized after machine discharge, in slurries 95% lime-ash can be separated.Labor intensity is low, and good operational environment is, it can be achieved that clear
Clean production.Digestion machine will not produce harmful exhaust in digestion process, and the gas discharged is the water containing a small amount of calcium hydroxide
Steam, eliminates if desired for thorough, can carry out dust removal process by matching dust-extraction unit.
