Abstract
The utility model discloses a biaxial quicklime digester, including left and right spiral mixing shafts in parallel arrangement and centric rotation. Blades distributed on the mixing shaft are intertwined; the upper part of a corresponding cylinder against a hopper outlet is provided with an exhaust mouth connected with an exhaust tube. The digester can generate a mixing convection in the mixing process and make self-cleaning, thus not only increasing the digestion area but also avoids the cylinder jam and the mixing shaft fracture due to felted lime.
Description
Technical field
The utility model relates in a kind of metallurgical industry production process, the burnt lime digester in sintering or the pellet formation blending process.
Background technology
At present, carry out in the burden process of sintering, pellet formation,, its unslaked lime is added water digestion,,, effectively improve the balling ratio of compound bead because the slaked lime specific surface area is big so that form slaked lime for improving the mixture granulation effect at metallurgy industry.What traditional burnt lime digester adopted is that screw-blade stirs, transmission.In order to improve the digestion effect, and on screw-blade, add stirring rod.But, because unslaked lime volumetric expansion in digestive process, viscosity are big, the phenomenon of dead screw-blade and axle often appears sticking with paste, the resistance of screw-blade is strengthened, so that phenomenon such as off-axis often takes place; Adopt the albarium digestive organ of spiral way, because screw-blade plays main prograding, make its mixing effect very undesirable, more to the caking of its postdigestive lime " particle " shape, can not avoid the problems referred to above even on screw-blade, be added with the digestive organ of stirring rod.Traditional digestive organ also fails to consider the influence to operating environment and operation effectiveness of a large amount of steam that unslaked lime produces in digestive process.
The utility model content
The purpose of this utility model is to provide a kind of twin shaft burnt lime digester, makes to produce in its digestive process to stir convection current, and has self-cleaning function, has eliminated bonding, makes it unslaked lime and water and more can effectively mix; Simultaneously, also solved the problem of discharge of steam.
For achieving the above object, technical solution of the present utility model is achieved like this: a kind of twin shaft burnt lime digester, it has adopts two to be arranged in parallel and to the left and right helical stir axle to heart rotation, the interlaced arrangement of blade that distributes on this two stir shaft; Being provided with steam drain on the cylindrical shell top of discharge gate correspondence is connected with blow-off line.
The technical solution of the utility model also comprises:
Can be to flexibly connect or fixedly connected between described blade and the stir shaft.
Described blade is equidistant arranged distribution, or non-equidistant arranged distribution, or becomes close arranged distribution gradually by dredging.
Positively effect of the present utility model is: this digestive organ has adopted the twin axle whipped form, has stirring, pulverizes multiple action and effects such as caking and self-cleaning.Make it unslaked lime and water and more can effectively mix, simultaneously " particle " shape caking that produces is played destruction in digestive process; Utilize cross-compound arrangement in whipping process, to produce and stir convection current, strengthened the digestion area; Twin shaft is when stirring, and the blade on the diaxon can be swept mutually and scrape the lime that is bonded on blade and the stir shaft, and unique self-cleaning function has effectively avoided causing because of bonding lime the generation of problems such as the obstruction of stir shaft, barrel even off-axis; But also on cylindrical shell, set up steam drain, and be discharged to outside the factory building by pipeline, eliminated the influence of steam to operating environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, to this novel being further described.
By Fig. 1, twin shaft burnt lime digester shown in Figure 2, it comprises that body 4 and cylindrical shell 5 link into an integrated entity.Motor 3 by body 4 one side settings is connected to step-down gear 1 by shaft joint 2, output terminal by step-down gear 1 is connected to wheel casing 8 by shaft joint 7, the a pair of gear that output terminal by wheel casing 8 connects, being provided with two on its gear is arranged in parallel and to the left and right helical stir axle 9 to heart rotation, when twin shaft is stirred, more fully, evenly.The blade 10 interlaced arrangements that distribute and be provided with on this two stir shaft 9 have prograding and sweep the self-cleaning function of scraping bonding lime mutually, have effectively avoided the generation because of stir shaft, barrel obstruction and off-axis phenomenon that bonding lime causes.Produce of the influence of a large amount of steam in the quicklime slaking process for solving, and be provided with steam drain 6 on cylindrical shell 5 tops of discharge gate 11 correspondences and be connected with blow-off line to operating environment.
The blade 10 that is provided with on the stir shaft 9 described in above-mentioned, the mode of connection between its two body can be fixedly connected, promptly utilizes welding process, or axle 9 is made with blade 10 integral body; For considering that blade 10 easily produces wearing and tearing and maintenance problem in whipping process, also can make blade 10 adopt screw thread to flexibly connect or make blade 10 that base is set with stir shaft 9 and be connected by bolt.This mode can efficiently solve the dismounting and change of blade 10.
In addition, the blade 10 in above-mentioned can be equidistant arranged distribution, or non-equidistant arranged distribution; The arrangement that also can be blade 10 becomes close gradually by dredging.
Described blade is installed by symmetric form and is provided with, and can mainly be to select can satisfy stronger propulsive force by asymmetric setting also.
Claims (3)
1, a kind of twin shaft burnt lime digester, comprise motor, connect wheel casing by step-down gear, be connected to be installed in body and the tube intravital stir shaft and on blade, it is characterized in that it has two parallel rows and to the left and right helical stir axle (9) to heart rotation, this two stir shaft (9) is gone up the interlaced arrangement of blade (10) that distributes; Being provided with steam drain (6) on corresponding cylindrical shell (5) top of discharge gate (11) is connected with blow-off line.
2, by the described twin shaft burnt lime digester of claim 1, to it is characterized in that between described blade (10) and the stir shaft (9) be flexible connection or fixedly connected.
