Description
Technical field
The present invention relates to Industrial Stoves field, in particular for a kind of homogeneous low temperature circular cone drawing mechanism in mechanization lime shaft kiln.
Background technology
Drawing mechanism in mechanization lime shaft kiln is a key mechanism of its mechanized operation, it ensures the cross-sectional uniformity discharging along kiln except being used for, balanced ventilation at the bottom of kiln, also should play the production capacity regulating kiln and the effect material bondd in kiln being had to breaking capacity.The discharging equipment of current employing mainly contains following several:
(1) spiral shell cone discharging machine
Spiral shell cone discharging machine is a kind of discharging equipment that current domestic Large Lime shaft kiln the most often uses.The main body of spiral shell cone discharging machine is one with the turriform spiral cone care feed tray of blast cap.Care feed tray is bearing on 8 support rollers, and is axle center with hollow shaft, is driven, rotated by bevel gear along circuit orbit by drive apparatus.In the side of revolution care feed tray, discharging scraper plate is housed, along with the continuous rotation of care feed tray, on dish, material is just drawn off.
The advantage of spiral shell cone discharging machine is comparatively even along the cross section discharging of kiln body, also has certain breaking capacity to sporadic materials from bonding phenomenon.Shortcoming is that at the bottom of kiln, ventilation is uneven, and can not realize the sufficient heat exchange of combustion air and material, structure bulkier, metal consumption is high, and operational administrative is more complicated.
(2) disk discharging machine
Disk discharging machine is made up of discharging machine main body, blast cap, airduct, lower funnel etc.The structure of disk discharging machine is similar to common disk feeder with operation principle, i.e. the main body of discharging machine---and the disk with blast cap is driven around fixing vertical shaft rotary by transmission mechanism.In the side of discharging disk, discharging scraper plate is housed, along with the rotation of disk, material draws off along discharging scraper plate.
The major advantage of disc type discharging machine is: structure is simple, and easily manufacture, weight of equipment is also lighter.Shortcoming is: do not squeeze broken effect to binding material block in kiln, when there being binding material block to be stuck in blast cap place, blanking also can be caused uneven; Easily cause inclined windage yaw fire at the bottom of kiln; The sufficient heat exchange of combustion air and material can not be realized.
(3) supporting plate discharging machine
Supporting plate discharging machine is that current state internal volume is at 150m
3the main discharging equipment that following lime vertical kiln adopts.According to the version of supporting plate and the difference of employing quantity, supporting plate discharging machine is respectively single mount plate, double bracket plate or many supporting plates discharging machine etc.
The advantage of supporting plate discharging machine is: structure is simple, reliable, and weight of equipment is light, easily manufactures.Shortcoming is: discharging lack of homogeneity, to binding material without fragmentation; Easily cause inclined windage yaw fire at the bottom of kiln; The sufficient heat exchange of combustion air and material can not be realized.
(4) roll-type discharging machine
Roll-type discharging machine is made up of the discaling roll of several (4 ~ 10) parallel distributions, these rods under the effect of transmission device, relative rotation paired on bearing block.Material is drawn off along with the rotation of discaling roll from gap.The rotating speed of rod can output as requested regulate by means of buncher or variable speed electric motors, particularly.
The advantage of roll-type discharging machine is: to bonding lime material block can carry out fragmentation, be also conducive to air at the bottom of kiln equally distributed enter kiln.Shortcoming is: weight of equipment is comparatively large, needs the rotation direction of often conversion discaling roll, management trouble; Can not realize the sufficient heat exchange of combustion air and material, product energy consumption is high.
Summary of the invention
Object of the present invention is exactly the above-mentioned various deficiency that will overcome existing several drawing mechanism existence, and provide a kind of rational in infrastructure, be easy to grasp, grey matter is even, energy-saving and cost-reducing homogeneous low temperature circular cone drawing mechanism.
Concrete scheme of the present invention is: for a kind of homogeneous low temperature circular cone drawing mechanism in mechanization lime shaft kiln, there is a bearing block, in bearing block, bearing is housed, vertically arranged main shaft is coated with in bearing, it is characterized in that: dirt-proof boot is equipped with in the main shaft outside below bearing block, and the main shaft above bearing block is equipped with rotating disk, and the middle part of rotating disk is provided with aeration tower, be provided with air channel in the middle part of rotating disk to be communicated with aeration tower, the card of rotating disk have some discharging air vents.
Rotating disk described in the present invention is installed on main shaft by a wheel hub, and wheel hub is provided with umbrella skeleton support and connection rotating disk, and umbrella skeleton is provided with discharging air vent.
Aeration tower described in the present invention includes cylindricality tower body and taper tower top, and tower body and tower top inside are ventilation cavity, and have multiple discharging air vent on tower body and tower top wall.
For being conducive to carrying out fragmentation to binding material block, in the present invention, on the upper disk surface of rotating disk, be designed with multiple dog.
Have employed rotating disk and compartment ventilated tower type structure in the present invention, fragmentation can be had to the bonding material block of material, achieve uniform discharge; And the tower body of aeration tower and tower top all have air vent, add the draught area in the middle part of kiln body, considerably increase heat exchange area and the heat-exchange time of up combustion air and the descending lime material entering kiln body, fully, heat exchange is realized uniformly, thus effectively reduce drop temperature, increase the temperature of combustion air, reach energy-saving and cost-reducing object.
The present invention has rational in infrastructure, easy and simple to handle, significantly improves the quality of product, and drop temperature on average reduces 15 ~ 20 DEG C, and thermal energy consumption on average reduces 7%, and percentage of damage have dropped 4%, significantly reduces the advantages such as the discharge of pollution.
