Abstract
The utility model discloses a kind of feed coal knot screen, including raw material coal bunker, raw material coal bunker upper end is provided with feed pipe, feed pipe upper end is connected with feed coal tremie pipe, longitudinally through being provided with drive shaft in feed coal tremie pipe, being provided with broken blade in drive shaft, drive shaft one is connected through feed coal tremie pipe with motor output shaft；The double-edged fine-toothed comb of cross direction profiles it is provided with in feed coal tremie pipe below drive shaft.This utility model simple in construction, easy to install, it is convenient that maintenance is changed, and according to raw coal size, processes suitable sieve aperture, it is to avoid chute blockage, removes the foreign material such as the Caulis et Folium Oryzae, the linen-cotton that contain in feed coal so that burner blocking channel is unimpeded, it is ensured that burner stable operation.
Description
Technical field:
This utility model relates to Coal Chemical Industry and generating produces apparatus field, particularly relates to a kind of feed coal knot screen.
Background technology:
According to Coal Chemical Industry and the requirement of electrification technique as well as, space flight furnace apparatus is from storing the feed coal come with induction system through raw material
Coal bunker mouth enters in feed coal bunker, and feed coal is delivered in coal pulverizer after vibrating bunker and Gravimetric Coal Feeders measure.
Owing to containing the foreign material such as Caulis et Folium Oryzae, linen-cotton in feed coal, these foreign material can not be removed in coal pulverizer, eventually enters
Enter to burner blocking channel, affect burner stable operation.
Utility model content:
The purpose of this utility model is to provide a kind of feed coal knot screen, effectively remove feed coal contains Caulis et Folium Oryzae,
The foreign material such as linen-cotton so that burner blocking channel is unimpeded, it is ensured that burner stable operation.
The technical solution of the utility model is as follows:
Feed coal knot screen, including raw material coal bunker, raw material coal bunker upper end is provided with feed pipe, it is characterised in that described
Feed pipe upper end is connected with feed coal tremie pipe, longitudinally through being provided with drive shaft in feed coal tremie pipe, and drive shaft
On broken blade is installed, drive shaft one is connected through feed coal tremie pipe with motor output shaft；Below drive shaft
The double-edged fine-toothed comb of cross direction profiles it is provided with in feed coal tremie pipe.
Described feed coal knot screen, it is characterised in that the feed coal blanking between described drive shaft and double-edged fine-toothed comb
Being rotatablely equipped with two free rotating shafts spaced apart in pipe, two free rotating shafts are parallel to each other with drive shaft, two freedom
Rotating shaft is positioned at the both sides of drive shaft projection, and free rotating shaft is outward distributed many puddlers along carrying out.
The utility model has the advantages that:
This utility model simple in construction, easy to install, it is convenient that maintenance is changed, and according to raw coal size, processing is suitably
Sieve aperture, it is to avoid chute blockage, removes in feed coal the foreign material such as the Caulis et Folium Oryzae, the linen-cotton that contain so that burner blocking channel is unimpeded, it is ensured that burner
Stable operation.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
See accompanying drawing:
Feed coal knot screen, including raw material coal bunker 1, raw material coal bunker 1 upper end is provided with feed pipe 2, and feed pipe 2 upper end is with former
Material coal tremie pipe 3 is connected, and longitudinally through being provided with drive shaft 4 in feed coal tremie pipe 3, drive shaft 4 is provided with brokenly
Broken blade 5, drive shaft 4 one is connected through feed coal tremie pipe with motor 6 output shaft；Feed coal below drive shaft 4
The double-edged fine-toothed comb 7 of cross direction profiles it is provided with in tremie pipe.
Two free rotating shafts spaced apart it are rotatablely equipped with in feed coal tremie pipe between drive shaft 4 and double-edged fine-toothed comb 7
8, free rotating shaft 8 is produced by the feed coal freely falling body fallen after clashing into and rotates, two free rotating shafts 8 and drive shaft 4 phase
The most parallel, two free rotating shafts 8 are positioned at the both sides of drive shaft 4 projection, and free rotating shaft 8 is distributed many stirrings along carrying out outward
Bar 9, puddler can filter out the foreign material such as Caulis et Folium Oryzae, the linen-cotton that the broken blade of a part fails to crush, simultaneously also can be to some blocks
Shape feed coal crushes again.
