Steel energy consumption is reduced, steel products structure is improved, improves quality and quality, seeks the approach for solving steel scrap shortage, realizes
The comprehensive utilization of resource so that non-blast furnace ironmaking technique is increasingly paid attention to.Although it is non-that there are no any types so far
Blast furnace iron-making process can surmount the absolute predominance of the high power of blast furnace, large capacity, but as the useful supplement of traditional handicraft, non-
Traditional handicraft still occupies one seat.China's natural gas lacks, but the characteristics of rich coal resources, determines that coal base is direct
Reduction technique is the preferred technique of China's Development of Direct-Reduced Iron.
What Direct Reducing Iron Process used at present enter stove material for the pellet (8~15mm) of extreme hardness, when mine ball most
When major diameter face is coplanar with shear surface, huge reaction force will be generated to the shaft of feeding device, the reaction force is for motor
And the continuously running of speed reducer, stablizing for operating current generate extremely disadvantageous influence；If more mine ball is piled up in shearing simultaneously
Face will cause shaft that can not rotate, and form swollen material, in turn result in the consequence that production can not continue；If in addition, by select compared with
The shaft that high-hardness makes improves power of motor or increases one of which or the several ways of speed reducer torque to solve
Certainly swollen material problem, will greatly increase the equipment cost of feeding device, be unfavorable for commercial scale extension.
Utility model content
A kind of in order to overcome the deficiencies of the prior art, the utility model provides coal-based direct reduction iron vertical heater charging dress
It sets, not being added to this under the premise of significantly, avoids getting stuck, ensure that blanking is smooth.
In order to achieve the above object, the utility model is realized using following technical scheme：
A kind of vertical furnace feeder of coal-based direct reduction iron, including motor, speed reducer, shaft, ripple compensation connector,
Shell, blanking discaling roll, ripple compensation flange；The motor is connected by shaft coupling with speed reducer, speed reducer by shaft coupling with
Shaft is connected, and blanking discaling roll is mounted in the middle part of shaft, and shaft both ends are mounted on bearing block, and bearing block is connected by ripple compensation
Part is connected on shell；The case top is equipped with feeding mouth, and bottom is equipped with discharge port, and feeding mouth passes through ripple compensation flange
It is connect with top feed bin, discharge port is connect by ripple compensation flange with lower volume.
The blanking discaling roll circumferencial direction is evenly distributed with multiple grooves.
The feeding mouth is infundibulate, and discharge port is inverted funnel shape.
The ripple compensation flange includes bellows, flange；Flange is fixed in bellows both ends.
The ripple compensation connector includes connecting seat, radiation fins；Radiation fins is fixed on connecting seat.
The shell is columnar structured.
Compared with prior art, the utility model has the beneficial effects that：
The utility model axis body is connect with shell by ripple compensation mode, shell feeding mouth by ripple compensation flange with
Top feed bin connection, discharge port are connect by ripple compensation flange with lower volume；When hardness is higher and larger (the left sides 15mm of granularity
It is right) material (pellet) by shell and groove shear surface when, shell can will can cause to get stuck originally by reversed displacement
Pellet be received into groove and by rotate by it by the smooth discharge of lower part of the housing discharge port, avoid and get stuck, ensure that
Production is smoothed out；The damage for also avoiding reaction force countershaft, speed reducer, motor simultaneously, increases the use of device
Service life reduces device later maintenance cost.

Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, Figure 3 shows, the vertical furnace feeder of a kind of coal-based direct reduction iron described in the utility model, including
Motor 1, speed reducer 2, shaft 3, ripple compensation connector 4, shell 5, blanking discaling roll 6, ripple compensation flange 7.
Motor 1 uses y series motor, speed reducer 2 to use cycloidal planetary gear speed reducer.Shaft 3 is multidiameter structure, and middle part is
Axis platform, axis platform both ends are axle journal, and axle journal both ends are spindle nose.Blanking discaling roll 6 is roll shape structure, and circumferencial direction is evenly distributed with multiple grooves
11.Ripple compensation flange 7 is made of bellows 12, flange 13, and flange 13 is fixed in 12 both ends of bellows.Ripple compensation connector
