Description
Technical field
The present invention relates to the apparatus for carrying out quicklime slaking reaction, more particularly to high-temperature energy-conservation quicklime slaking reacts
Tank.
Background technology
Quick lime is being commonly called as calcium oxide, the finished product of its deep processing, and white lime is widely used in building, chemical industry, steel smelting
The all trades and professions such as gold, sewage disposal, leather processing and flue gas desulfurization.White lime is mainly generated by quick lime and water reaction, its
Reaction process is referred to as the curing or digestion of lime, at present, industrially generally carries out quick lime using burnt lime slaking device and disappears
Change reaction, quantitative quick lime and quantitative water are added into burnt lime slaking device, blender is set in slaking apparatus, makes life
Lime is reacted with water, forms white lime slurry, regathers slurry and processing is dried, form finished product white lime.Due to life
Lime often exists with block structure, caustic lime block and water is stirred although employing blender in digestion reaction, to add
The progress of fast digestion reaction, but since the block structure of quick lime is not of uniform size, and can often be mingled with other and cannot react miscellaneous
Matter, often occurs reacting halfway situation, influences the quality of white lime slurry, makes the life stone that remnants are also had in final finished product
Grey block, since quicklime slaking reaction is not thorough, during the use of white lime, since quick lime can be with the moisture in air
Directly reacted, industrial processes can be directly affected, influence product quality, caused damages
So based on the above problem, existing digestion reaction device is solved there is an urgent need for a kind of technical solution at present and digest instead
Answer halfway defect.
The content of the invention
It is an object of the invention to solve existing digestion reaction device to carry out the halfway technical problem of digestion reaction, there is provided
It is a kind of to make the quicklime slaking retort that digestion reaction carries out more thoroughly.
To achieve these goals, the technical solution adopted by the present invention is：
High-temperature energy-conservation quicklime slaking retort, including tank body and actuating unit, tank body one end top are provided with note
The mouth of a river and feed injection port, rabbling mechanism is provided with the tank body, and the actuating unit drives rabbling mechanism to rotate, the tank
It is provided with overflow ducts and slurry transfer passage in vivo, the slurry transfer passage is arranged at tank wall close to tank base,

The high-temperature energy-conservation quicklime slaking retort of the application, by setting overflow ducts and slurry defeated at the same time in tank body
Passage is sent, the slurry digested completely exports tank body in advance by overflow ducts, is only left the quick lime not digested completely in tank body
With the mixed slurry of water, digestion reaction is continued by the stirring of rabbling mechanism, output slurry in batches, it is ensured that digestion is anti-
The thorough progress answered.
As the preferred solution of the application, the feed injection port is connected with reducing mechanism.Since quicklime particles degree is got over
Small, the quantitative quick lime digestion time used completely is fewer, so by setting reducing mechanism in feed injection port, by raw stone
Ash carries out preliminary crushing, reinjects tank body, the time effectively used in reduction digestion reaction, further makes digestion reaction more thorough.
As the preferred solution of the application, partition plate is provided with the tank body, it is anti-that tank body is divided into first by the partition plate
Groove, the second reactive tank and the 3rd reactive tank are answered, the rabbling mechanism runs through three reactive tanks, the feed injection port and at the same time
One reactive tank connects.Three reactive tanks will be divided into by partition plate in tank body, raw material injects the first reactive tank, and mixed slurry is through stirring
The stirring of mechanism is mixed, passes sequentially through the first reactive tank, the second reactive tank and the 3rd reactive tank, has obtained thoroughly stirring, has made original
Material carries out thoroughly digestion reaction.
As the preferred solution of the application, the actuating unit includes motor and the retarder being connected with motor, institute
Retarder is stated to be connected with rabbling mechanism.Rabbling mechanism is driven by actuating unit, motor rotation is controlled, can easier control
The rotating speed of rabbling mechanism, can change motor rotation speed according to the situation of output slurry, digestion reaction is more smoothly carried out,
Also electric energy is saved.
As the preferred solution of the application, the rabbling mechanism is Stirring axis, and the Stirring axis is included with subtracting
The rotation axis of fast device connection and the helical blade being arranged in rotation axis.By setting helical blade on Stirring axis, make
The mixed slurry of quick lime and water is sufficiently mixed, and is conducive to the progress of digestion reaction, reduces the digestion reaction time.
As the preferred solution of the application, slurry delivery port is provided with the partition plate and for through Stirring axis
Circular through hole, the slurry delivery port connects with slurry transfer passage.By setting slurry delivery port and slurry on partition plate
Transfer passage connects, and the slurry for obtaining abundant digestion reaction is sent into slurry transfer passage by slurry delivery port in time, reduces tank
The mixed material of digestion reaction in body, it is ensured that the mixed material for not carrying out digestion reaction is smoothed out digestion reaction.
As the preferred solution of the application, heating unit is provided with the tank body, the heating unit connects with water filling port
Connect.Since within the specific limits, the initial temperature of digestion reaction is higher, the time used in the complete digestion reaction of quantitative quick lime gets over
Short, so by connecting heating unit in water filling port, heating injects the initial temperature of the water in tank body, effectively reduces digestion reaction
Time.
As the preferred solution of the application, temperature monitor is provided with the tank body.Put since digestion reaction is one
Thermal process, by the set temperature monitor on tank body, monitors the temperature of mixed slurry in tank body, is set when temperature exceedes at any time
During value, heating unit can be closed, saves the energy.
In conclusion by adopting the above-described technical solution, the beneficial effect of the application is：
Overflow ducts and slurry transfer passage are set at the same time in tank body, the slurry digested completely is shifted to an earlier date by overflow ducts
Tank body is exported, is only left the mixed slurry for the quick lime and water not digested completely in tank body, the stirring for passing through rabbling mechanism continues
Carry out digestion reaction, output slurry in batches, it is ensured that the thorough progress of digestion reaction.
The beneficial effect of the application other embodiment is：
1st, by setting reducing mechanism in feed injection port, quick lime is subjected to preliminary crushing, tank body is reinjected, effectively subtracts
Time used in few digestion reaction, further make digestion reaction more thorough；
2nd, by connecting heating unit in water filling port, heating injects the initial temperature of the water in tank body, effectively reduces digestion
Reaction time.
