Abstract
The utility model provides a secondary drying unit for nanoscale superfine calcium carbonate. The secondary drying unit is composed of a double-blade dryer of a primary drying device, a drum tube bundle dryer of a secondary drying device and a screw conveyor unit connected between the double-blade dryer and the drum tube bundle dryer. The double-blade dryer comprises a blade drying power device, a double-blade drying tank and a blade dryer discharging funnel. The drum tube bundle dryer is composed of a rotating device and a drying drum, the drying drum comprises a drum body, an inner heating tube bundle located in the drum body and an outer heating tube bundle surrounding the drum body, the inner heating tube bundle is divided into a stainless steel tube bundle and a carbon steel tube bundle, and both the stainless steel tube bundle and the carbon steel tube bundle are arranged in the shape of radial fins. Compared with the prior art, the secondary drying unit for nanoscale superfine calcium carbonate has the advantages of being high in drying efficiency, low in energy consumption, good in drying uniformness, easy to maintain and convenient to use.
Description
Technical field
The utility model relates to Machining Technology field, relates in particular to a kind of nanometer grade super fine calcium carbonate secondary drying unit.
Background technology
The drying process of nanometer grade super fine calcium carbonate is mainly completed by tray drier at present, but because tray drier heat exchange area is limited, fault rate is high, and drying capacity is low, every drying production line annual production is below 5000 tons, thereby directly affected the production of nanometer grade super fine calcium carbonate.
Given this, be necessary to provide a kind of New drying equipment to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of new nanometer grade super fine calcium carbonate secondary drying unit, the good uniformity that its drying efficiency is high, energy consumption is low, dry, and maintenance and repair is simple, and easy to use.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of nanometer grade super fine calcium carbonate secondary drying unit, by the two blade dryers of one-level drying device, secondary drying device cylinder train pipe drying machine and the conveying worm being connected between two blade dryers and cylinder train pipe drying machine form, described pair of blade dryer comprises: blade is dried power set, two blade drying chambers, blade dryer discharge funnel, described pair of blade drying chamber comprises W shape housing, be positioned at 2 groups of paddle shafts of W shape housing, the double layer hollow structure that described W shape housing is, described paddle shaft is hollow structure, described cylinder train pipe drying machine is comprised of whirligig and drying drum, and the external heat tubulation that described drying drum comprises cylindrical shell, be positioned at the heating tubulation of cylindrical shell and be surrounded on cylindrical shell outside forms.
As the further improvement of the technical program, described interior heating tubulation is divided into stainless steel tubulation and carbon steel tubulation two parts, and stainless steel tubulation and carbon steel tubulation are radial fin shape arrangement mode.
Compared with prior art, the utility model nanometer grade super fine calcium carbonate secondary drying unit one-level drying device adopts two blade dryers, secondary drying device adopts cylinder train pipe drying machine, solved traditional tray drier heat exchange area limited, fault rate is high, the problem that drying capacity is low, has improved the production capacity of nanometer grade super fine calcium carbonate drying production line greatly.
