In groove, material is made thinly by film-distributing device（It is membranaceous）Cylinder surface is attached to, heating medium is connected with roller, more using steam,
Pressure is typically in 0.2~6MPa, and for temperature between 120~150 DEG C, material makes its hygroscopic water in roller rotation by the heat transfer of simple wall
Vaporization, rolling letter are completed process, the dried materials such as cloth film, vaporization, dehydration in a rotation period and scraped by scraper, from going out
Material mouth is discharged.The moisture evaporated in heat transfer, it can be incorporated into depending on its property in corresponding processing unit and carry out by enclosed hood
Trap dust or discharge.
Traditional cylindrical drier, larger suitable for material density, water content is more, and material proportion is still after dehydration
The drying process of larger material, and operation temperature is mostly at 120-150 DEG C, for the drying of precipitated calcium carbonate before encapsulation
Operation just seems not bery applicable.Because the filter cake after carbonization and filtering by being needed after drying obtains finished product nanometer light carbonic acid
Calcium, product proportion and water content are all relatively low, and the requirement for mass transfer temperature is higher, and mass transport process can not produce too big disturb
It is dynamic, the loss of product calcium carbonate otherwise can be caused more serious.Although having some to overcome the improved technology of disadvantage mentioned above to occur,
A kind of rotary roller dryer as disclosed in application number 201420524365.X, the mode for employing inner coil pipe heating are changed
Enter, but also result in the shortcomings that Flow of Goods and Materials resistance is big, and production efficiency declines.
Utility model content
For conventional drum type drying machine because mass transfer temperature is low, the shortcomings of big is disturbed to caused by material, is not suitable for
The reality of precipitated calcium carbonate drying process, produce the drum-type that nanometer light calcium carbonate uses the utility model proposes a kind of and do
Dry machine.
To achieve the above object, the utility model provides following technical scheme：A kind of rolling for producing nano-calcium carbonate and using
Cylinder drying machine, including charging aperture, preceding rolling ring, travelling gear, motor-speed reducer, casing, rear rolling ring and discharging opening, it is described
There is certain angle of inclination between charging aperture and discharging opening, can be adjusted according to the dry materials time；The motor-speed reducer
Power is provided, rolled by travelling gear casing on preceding rolling ring and rear rolling ring along axis；The casing internal arrangement
There is the interior heating tube bundle being inwardly gradually shortened, tube bank is internal to be connected with heating medium, and the flow direction of the heating medium is by discharging
Mouth flows to charging aperture direction.
Preferably, the preceding rolling ring and rear rolling ring carry height-adjustable lowering or hoisting gear, can according to material properties and
Heat transfer drying time carries out the regulation at angle of inclination.
Preferably, the interior heating tube bundle is process by stainless steel, and inside is connected with conduction oil and is used as heating medium,
Heat conduction oil temperature can reach 250 DEG C.
Compared with prior art, the beneficial effects of the utility model are：
1. heat transfer area is big, the thermal efficiency is high, dries the thermal efficiency more than 90%；Dry materials power consumption is few, and expense is low, production
Ability is big, temperature-controllable, and to the strong adaptability of material characteristic, the uniformity of dry materials is good；Due to the interior heating being gradually shortened
Tube bundle designs so that filter cake calcium carbonate flow resistance is small, low in energy consumption；Internal duct uses high-quality seamless steel pipe, ensure that equipment
Service life.Transmission parts and critical positions select alloy material, and intensity is big, wear-resistant, service life length, plant maintenance letter
Single, maintenance cost is low.
2. the power motor of drying machine is variable-frequency motor, by driving cylinder after size The gear deceleration after being slowed down by reductor
Revolution, also rotating speed can be adjusted according to material requirement by adding frequency-conversion control cabinet, facilitate remote control.
