Description
Technical field
This technology relates to device for discharging, specifically, is a kind of vibration type device for discharging。
Background technology
Device for discharging is mainly used in vertical furnace (stove), is typically mounted at bottom, and its effect is to be controlled from the internal material discharging out of vertical furnace (stove)。
Such as, the existing vertical limekiln of solid fuel with granular solids fuel production Calx such as coal, coke, semi-coke, generally comprises cylinder, is provided with distribution device in cylinder upper end, cylinder lower end is provided with device for discharging, there is air-supply arrangement above device for discharging。
Distribution device is generally adopted bend pipe distributing device or bell distributing device or revolving top, solid fuel and ore are promoted to cylinder top through lifting device, in bend pipe distributing device or bell distributing device or revolving top feeding cylinder。Owing to solid fuel and ore granular size differ, when falling in cylinder, (bulky grain rolls to around to produce segregation phenomenon, little granule concentrates on body centre), material skewness, cylinder cross section everywhere, solid fuel and ore some places are many, and some places are few。Due to material skewness, cylinder cross section everywhere, material density is different, and the combustion air sent into by air-supply arrangement amount throughout is also different。And, material is in the process moved down, and resistance is different everywhere。It is relatively big that these factors have resulted in the speed difference that on same cross section, limekiln, temperature and material decline, and temperature and the time of calcining that namely material is calcined in kiln are uneven, and the lime quality therefore produced is uneven。Further, since cylinder upper end is uncovered, flue gas is discharged either directly through cylinder upper end, it is difficult to be collected flue gas processing, contaminated environment。
Further, since the limitation of reinforced, discharging, air blast mode, existing solid fuel particularly burn raw coal, coke lime vertical kiln production capacity all smaller。
At the various lots of coal-fired lime vertical kiln of China owing to equipping backwardness, product quality is low, environmental pollution is serious, many places have begun to forbid producing, if but adopt the limekiln such as Maers Kiln, sleeve kiln of importing technology, Fu Kasi twin beams kiln, simon double; two D kiln and rotary kiln etc., not only investment is big, production cost is high, most requirement is gaseous fuel or levigate coal dust, does not meet China's national conditions to fire raw coal large in number and widely distributed。
Controlling the device for discharging of the bottom discharge opening discharging in the vertical limekiln of solid fuel, because being in hot environment, the device for discharging structure in the limekiln of foreign technology is extremely complex, and cost is high, maintenance and repair difficulty；The device for discharging in domestic technique limekiln, it is difficult to discharging is uniform, and automatic control level is relatively low。
Summary of the invention
The purpose of this technology provides one can material falling speed and falling amount effectively be controlled, adapt to higher temperature discharging environment, discharging uniform and stable more, even can the vibration type device for discharging of multiple spot discharging simultaneously。
This vibration type device for discharging, including bearing material device, vibrator, bearing material device and vibrator are rigidly connected, and bearing material device is connected with fixing support or suspension bracket by flexible member；Vibrator is positioned at airtight case, and case two ends connect cooling blast pipe, discharge pipe respectively；Case is positioned at the housing of closing, and housing upper has material inlet, and lower housing portion has material outlet；Blast pipe, discharge pipe traverse housing。
The beneficial effect of this technology: bearing material device is connected with fixed support or suspension bracket by flexible member, and when vibrator action, namely bearing material device vibrates, and being positioned at the material above bearing material device can be activated and fall from bearing material device。Owing to adopting the case ventilated that vibrator is cooled down, it is ensured that vibrator reliably working in high temperature environments。This vibrator can electrically connect with Programmable Logic Controller, it is achieved automatically controlling this device for discharging。
During use, this vibration type device for discharging is arranged on the lower section of the dumping pit fallen for material of vertical furnace, vibrator action, and the material on bearing material device is vibrated activation and falls from bearing material device, and material just continues to fall by dumping pit。Dumping pit is connected with bearing material device by material channel, and usual bearing material device is more than the size of material channel, thus material will not free-falling when bearing material device is static。When vibrator action stops, material is motionless, is stuck on bearing material device, and material will not fall from dumping pit。By changing vibrator frequency of vibration, it is possible to control material falling speed and falling amount。Vibrator can be a kind of mechanism with vibrating motor；It can also be the mechanism with electromagnetic vibration generator。For the needs sealed, it is prevented that vertical furnace leaks out, and vibration type device for discharging is placed in the housing of closing。But generally, vertical furnace internal temperature is higher, in order to adapt to high temperature discharging environment, it is ensured that in service life, vibrator is arranged in the case of ventilation and is cooled the cooling of wind and is not affected by high temperatures。
The installation site of vibrator, a kind of form is in outside hot environment, and another form is in hot environment。
Described bearing material device has 2 or more than 2, is rigidly connected between bearing material device。When vibrator is positioned at outside hot environment, especially can be rigidly connected between multiple bearing material devices, and drive with a vibrator。So it is adapted to multiple feed, multiple discharge and meets the uniform requirement of discharging quantity。
Above-mentioned vibration type device for discharging, installs on housing and controls the material-level detecting device of controlling level in housing, and material-level detecting device is lower than bearing material device。Material level in housing can be detected by material-level detecting device, it is prevented that in housing, material is too much or very few。
Above-mentioned vibration type device for discharging, bearing material device, case inside paste refractory material。
Above-mentioned vibration type device for discharging, it is also possible to for other kilns, preheater, the hot environment discharging of cooler, feed。
