Description

A kind of continous way calcium oxide digestion machine of nano-calcium carbonate production

Technical field

The utility model belongs to machinery field, and in particular to the calcium oxide digestion in a kind of nano-calcium carbonate production process Machine.

Background technology

There are the digestion step of calcium oxide, calcium oxide in nano-calcium carbonate production process（Quick lime）Add in water input digestion machine Reacted, release amount of heat generation calcium hydroxide（Milk of lime）, carbonic acid is generated after milk of lime is passed through carbon dioxide carbonization 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 behaviour Make, existing reactor causes inconvenient for operation since structure setting is unreasonable, and low production efficiency and manual labor are big Shortcoming, 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.A kind of such as 201620063072.5 " energy saving height Imitate calcium oxide slaking apparatus " and 201620880220.2 " a kind of calcium hydroxide digestion machines ".

Due to the appearance of problem above, causing calcium oxide digestion step at this stage becomes restriction Production of Light Calcium Carbonate mistake Restrictive factor in journey, the demand for the digestion machine that production efficiency is high, easy to operate, security is good just seem very urgent.

Utility model content

The utility model is exactly to design and propose to solve determined above.

To achieve the above object, the utility model provides following technical solution：A kind of nano-calcium carbonate production it is continuous Formula calcium oxide digest machine, include feed inlet, babinet, bearing, sealing, rack, hood, exhaust outlet, peep hole, shaft coupling, Gear reducer, mucking machine, discharge port and motor unit are into the digestion machine shell is by rack supporting box and hood and row Gas port forms；The calcium oxide material and water enter box house by feed inlet, and the connection of gear reducer link is driven by motor Axis device rotates, and shaft coupling links bearing by being sealed, and rotating bearing drives the rotation slurry of box house to rotate, and adds Fast digestion reaction process；The vapor that the digestion machine produces, is discharged by the exhaust outlet on hood top；Open on the babinet top There is peep hole conveniently to carry out checking for reaction process；The calcium oxide digestion machine reaction product calcium hydroxide is discharged by discharge port, Unreacted reactant is discharged from mucking machine.

Preferably, the heat that the digestion machine reaction produces is cooled down by cooling water, when reaction stops or when cleaning The floss hole discharge that sets from bottom of waste liquid.

Preferably, two side roof part of babinet of the digestion machine is additionally provided with lifting lug, carry out maintenance for babinet to be lifted and Cleaning operation.

Compared with prior art, the beneficial effects of the utility model are：Good operational environment, realizes mechanization production, clearly Slag facilitates, and using the slag remover for digesting the installation of machine rear portion, can separate in lime slurry 95% lime-ash；Milk of lime quality Good, milk of lime is fine and smooth, and paste producing amount is high, and lime milk concentration is easy to adjust, by increasing, reducing feeding quantity milk of lime can be controlled dense Degree；Floor space is small, and unit volume yield is high, and material is almost full with whole babinet, and utilization rate is up to more than 90%；Digestion rate It hurry up, lime slaking rate is high.Due to taking full advantage of lime slaking heat release, material is in fluidized state all the time in digestion machine, disappears Heat loss is small during change, and digestion rate is very fast, and quick lime can digest completely at 15 minutes, since digestion temperature is high, at it The lime that cannot be digested under his process conditions can also be digested completely；Mechanization degree is high, and operation control is easy, digests, removes Slag fully achieves mechanization, and personnel's operation is not required in normal productive process, and labor intensity is low；Both ends sealer is specially designed, It can ensure never to leak, realize the clean and tidy health of production scene；PLC control system can be matched, PLC passes through analog signals （4-20mA）Through Frequency Converter Control inlet amount and engine speed, automated production is realized, the vector type frequency converter in control system Low-frequency torque compensation can be set by self study or manually, realizes that the low frequency high-torque of digestion machine starts, greatly improves and disappear The startability of change machine.Control system is handled dust-proof, moisture-proof, is allowed to be more applicable for more dirt, moist environment；Disappear Change machine will not produce harmful exhaust in digestion process, and the gas discharged is the vapor containing a small amount of calcium hydroxide, such as need Thoroughly to eliminate, dust removal process can be carried out by matching dust-extraction unit.
