Description
Technical field
This technology is related to device for discharging, specifically, is a kind of revolving spiral formula device for discharging.
Background technology
Device for discharging is mainly used in vertical furnace（Stove）, bottom is typically mounted at, it is to from vertical furnace that it, which is acted on,（Stove）It is internal
Material discharging out is controlled.
For example, the existing vertical lime of solid fuel with the granular solids fuel production lime such as coal, coke, semi-coke
Kiln, generally comprises cylinder, and cylinder upper end is provided with distribution device, cylinder lower end is provided with device for discharging, in device for discharging
Top there is air-supply arrangement.
Distribution device typically uses bend pipe distributing device or bell distributing device or revolving top, solid fuel and ore
Raw material is promoted at the top of cylinder by lifting device, is sent into by bend pipe distributing device or bell distributing device or revolving top
In cylinder.Because solid fuel and ore granular size differ, when falling into cylinder, segregation phenomenon is produced（Bulky grain
Rolled to around, little particle concentrates on body centre）, material skewness, in the cross section of cylinder everywhere, solid
Fuel and ore some places are more, and some places are few.Due to material skewness, in the cross section of cylinder everywhere,
Material density is different, and the amount of the combustion air sent into by air-supply arrangement throughout is also different.Moreover, material is being moved down
During, resistance is different everywhere.These factors have resulted in the speed difference that temperature and material decline on the same section in limekiln
Larger, i.e., the temperature and the time of calcining that material is calcined in kiln are uneven, therefore the lime quality produced is uneven.Separately
Outside, because cylinder upper end is open, flue gas is directly discharged by cylinder upper end, it is difficult to processing is collected to flue gas, pollutes environment.
Further, since charging, discharging, the limitation of air blast mode, existing solid fuel particularly burns raw coal, coke
Lime vertical kiln production capacity is all smaller.
In the various lots of coal-fired lime vertical kiln of China because equipment falls behind, product quality is low, environmental pollution is serious, permitted
Many places have begun to forbid production, but if double using limekiln such as Maers Kiln, sleeve kiln, the Fu Kasi of importing technology
Beam kiln, simon double D kilns and rotary kiln etc., not only invest big, production cost height, it is gaseous fuel or levigate coal that majority, which is required,
Powder, does not meet China large in number and widely distributed to fire the national conditions based on raw coal.
Control the device for discharging of the bottom discharge opening discharging in the vertical limekiln of solid fuel, because being in hot environment, state
The device for discharging structure in the limekiln of outer technology is extremely complex, and cost is high, and maintenance and repair is difficult；The discharging in domestic technique limekiln
Device, it is difficult to which discharging is uniform, and automatic control level is than relatively low.
The content of the invention
The purpose of this technology provides one kind and material falling speed and falling amount effectively can be controlled, and adapts to higher temperature and goes out
Expect environment, discharging more uniform and stable, the revolving spiral formula device for discharging that even can be simultaneously discharged with multiple spot.
The revolving spiral formula device for discharging, including the helical blade, the drive gyroaxis that are fixed on gyroaxis turn around axis
There is bearing material device below dynamic gyration generator, gyroaxis；It is located at the front of the helical blade on gyroaxis on bearing material device
It is provided with blanking port.
The beneficial effect of this technology：In use, the revolving spiral formula device for discharging be arranged on vertical furnace, vertical preheater,
The lower section for the dumping pit that the confession material of upright radiator etc. falls, gyration generator（Such as motor）Action, drives gyroaxis
Rotate, material is promoted forward by helical blade, fallen from the blanking port on bearing material device.When gyration generator stopping action,
Gyroaxis stops operating, and material would not fall.By changing the speed that gyroaxis is rotated, can with control material falling speed and
Falling amount.
Above-mentioned revolving spiral formula device for discharging, helical blade and bearing material device are located in the housing of closing, and housing upper has
Material inlet, lower housing portion has material outlet, and helical blade is located at below material inlet, and bearing material device is located above material outlet；
Gyration generator is located at outside housing.The need for for sealing, prevent vertical furnace, vertical preheater, upright radiator etc. from leaking
Wind, revolving spiral formula device for discharging is placed in the housing of closing.But generally, vertical furnace, vertical preheater, vertical cooling
The internal temperatures such as device are higher, in order to adapt to high temperature discharging environment, it is ensured that service life, gyration generator（Such as motor）
It is not affected by high temperatures outside housing.Although gyroaxis, helical blade etc. are in cylinder, can high temperature resistant, while turn round fortune
Dynamic generator can be electrically connected with programmable controller, and realization is automatically controlled to the device for discharging.
Above-mentioned revolving spiral formula device for discharging, installs the material-level measure dress of controlling level in control housing on housing
Put, material-level detecting device is less than bearing material device.Material-level detecting device can be detected to the material position in housing, prevent thing in housing
Material is excessive or very few.
Above-mentioned revolving spiral formula device for discharging, bearing material device, case inside paste refractory material.
Above-mentioned revolving spiral formula device for discharging, bearing material device has multiple, has blanking port between adjacent bearing material device；Returned at one
Multistage helical blade is fixed with rotating shaft；There is a blanking port in the front of every section of helical blade.
Above-mentioned revolving spiral formula device for discharging, can be used for other kilns, preheater, the hot environment of cooler and unloads
Material, feed.
