Description of the drawings
Fig. 1 is according to danger incineration of waste bulk material feed system general illustration of the present utility model；
The enlarged diagram of rotary feeders of the Fig. 2 to illustrate in Fig. 1.
Specific embodiment
Describe danger incineration of waste bulk material feed system of the present utility model below in conjunction with the accompanying drawings in detail.People in the art
Member it should be appreciated that the embodiments described below be only to exemplary illustration of the present utility model, it is any not for making to which
Limit.
Referring to Fig. 1, according to danger incineration of waste bulk material feed system of the present utility model, for bulk material 20 is transported to
Burning disposal is carried out in incinerator 30 (such as rotary kiln).Bulk material 20 mentioned herein is primarily referred to as Jing and anticipates
Particle diameter is less than the block or granular solids danger waste of 50 × 50 × 80mm afterwards.
Feeding bin 1, the first weigher 3, the second weigher 5 are mainly included according to feed system of the present utility model and is returned
Turn blanking device 6.
Feeding bin 1 has closing housing, and housing is provided with material inlet 11 and material outlet 12.Can in 1 housing of feeding bin
To be provided with stock distributor 13, for dispersed material.1 housing bottom of feeding bin is provided with spiral reamer 4.In feeding bin
1 front end can arrange elevator (conveyer) 2, and bulk material 20 can lift elevator 2 top of feeding bin 1, and from
Material inlet 11 is entered in feeding bin 1.
Gravity is relied on () when conveying by storehouse formula due to bulk material, easily occur tying storehouse (flow stagnation) phenomenon in storehouse,
Once consequence is very serious caused by knot storehouse occurs, the material from several to tens tons is often accommodated in storehouse, can only often be disassembled
Material could be derived by feed bin.In order to prevent and dissolve the generation of the phenomenon in advance, spy is provided with the first metering to this utility model
Scale 3 and the second weigher 5 are being prejudged.First weigher 3 is weighed for entirety is carried out to feeding bin 1, the second metering
Scale 5 is weighed for the material to sending from the material outlet 12 of feeding bin 1.First weigher 3 is preferably sensed using loading
Device, is arranged on the outside of feeding bin 1.Second weigher 5 preferably adopt volume measurement scale, so as to can continuous conveying material, and
Energy metering material volume, draws the weight of conveying material by being multiplied by material proportion with the volume of material of metering.
When the feed system runs, (gravimetric value is m to the bulk material to be burned 20 being pre-metered0) from material inlet 11
Into feeding bin 1, the second weigher 5 is delivered to by spiral reamer 4 Jing after stock distributor 13 disperses, by the second weigher
After 5 weighings, Jing rotary feeders 6 are conveyed to incinerator 30.Measured in certain hour to burning dress by the second weigher 5
The weight of material for putting conveying is m2, it is m that the net weight of material in feeding bin 1 is measured by the first weigher 31.Continuously producing
During, work as m0-m2When value stabilization is in predetermined range of normal value, in showing feeding bin 1, Flow of Goods and Materials is normal；And work as m1Value by
Gradual change is big, m0-m2When value is more than predetermined normal value, then in imply that feeding bin 1, Flow of Goods and Materials starts to slow down, and continues development and goes down
May occur to tie storehouse phenomenon.Operator can be given warning in advance by the monitoring to above-mentioned gravimetric value, and take neutralizing to arrange in advance
Apply.For example with air bubble from 1 bottom of feeding bin to feeding bin 1 in squeeze into pressure-air and vibrated so that knot storehouse phenomenon
Just dissolved in the budding stage, so as to ensure continuous production, greatly improved production efficiency.
Referring to Fig. 2, rotary feeder 6 have shell 61 and it is interior turn device 62, shell 61 has charging aperture 63 and discharging opening 64,
Inside turn device 62 with central rotating shaft 65 and the multi-disc scraper plate 66 of 61 inwall of shell is extended to along central rotating shaft 65, it is preferred to use edge
Equally distributed 6 scraper plates 66 of circumferencial direction.Shell 61 and scraper plate 66 are all made using the metal of high-temperature heat treatment, and shell
61 inwalls and scraper plate 66 are all through grinding process.Gap is kept to coordinate between 61 inwall of 66 top of scraper plate and shell, therebetween
Gap be less than 0.5mm.Charging aperture 63 is connected with the second weigher 5, and discharging opening 64 is connected with incinerator 30 by blanking scraper-trough conveyer
Connect.During system operation, central rotating shaft 65 drives 6 66 uniform rotation of scraper plate under the driving of motor.Rotary feeder 6 it is upper
For receiving the material that the second weigher 5 gets off, middle two panels scraper plate 66 is used for keeping top and the bottom to completely cut off portion's two panels scraper plate 66, under
Portion's two panels scraper plate 66 is for blanking scraper-trough conveyer conveying material.Using the rotary feeder 6 of said structure, can either continuous conveying thing
Material, can effectively block the high hot-air burnt in incinerator 30 anti-channeling upwards again.
According to bulk material feed system of the present utility model, the connecting tube between elevator 2, elevator 2 and feeding bin 1
Transfer pipeline between road and feeding bin 1 and incinerator 30 all adopts closed.Bulk material 20 is all located in course of conveying
Carry out in closing space, so as to prevent the harmful gass volatilized in danger waste from outwardly discharging.In order to prevent 2 He of elevator
The inner space that deflagration accident, elevator 2 and feeding bin 1 occur in feeding bin 1 is all connected with extractor fan 9, and extractor fan 9 can
It is connected with the entrance with incinerator 30, is burnt so as to the flammable explosive gas of extraction are passed directly into incinerator 30.
Dust-precipitator 8 can be set before extractor fan 9, the dust that dust-precipitator 8 is collected by lock wind blanking device 19 be delivered in elevator 2 again to
Incinerator 30 is conveyed.In addition, explosion-proof valve 14 is also provided with the top of feeding bin 1, further ensure that safety.
According to danger incineration of waste bulk material feed system of the present utility model, it is capable of achieving bulk material real time measure, continuously enters
