Abstract
The utility model discloses a storage bin anti-blocking device which comprises a discharge bin; lining plates are arranged around the lower part of the discharge bin; the bottom surface of each lining plate is provided with a post; the wall of the discharge bin corresponding to the lining plate is provided with a stripy through hole; the post of the lining plate extends out of the through hole and is connected with a feeding screw; and the feeding screw is connected with a rotating shaft of a servo motor on the back side of the discharge bin. In this way, the problem of arching of materials at the lower part of the storage bin can be solved, so as to effectively prevent the discharge bin from being blocked.
Description
Technical field:
The utility model relates to feed bin, particularly the feed bin anti-block apparatus.
Background technology:
At present, mostly top is for being square or being columniform feeding bin for the run coal bin of domestic thermal power generation station-service, and the bottom is the blanking bin of the side's of being awl or circular cone.The mouth of feeding bin is big, and going out of blanking bin is young, and from the feeding bin charging, material drops out by the outlet of deadweight from blanking bin from top to bottom.The material that falls is owing to flow in conical vessel, so more flow downward, the flowing space is littler, material itself is just formed extruding, thereby increased by four right angle friction factor of square taper, and this is the main cause that results in blockage.The moisture of material in addition, the fineness degree ratio, variations in temperature, material is put time length in container, and chamber wall and coal friction factor size and gate structure etc. all are the reasons of stopping up.
In process of production, the easy arch camber of the material of feed bin bottom, particularly the putty phenomenon that takes place through regular meeting with interior feed bin bottom at coal gate 1.5m suitable for reading.
The utility model content:
Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of feed bin that can effectively prevent the tool anti-block apparatus that feed bin stops up.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of feed bin anti-block apparatus, comprise blanking bin, it is characterized in that, around this blanking bin bottom liner plate is set, the bottom surface of this liner plate is provided with cylinder, and the blanking bulkhead corresponding with this liner plate is provided with the through hole of strip, cylinder on this liner plate stretches out through hole and is connected with feed screw, and this feed screw is connected with the rotating shaft of the servomotor that is arranged on the blanking bulkhead back side.
Compared with prior art, the beneficial effect that the utility model had is: the utility model is set up liner plate around the blanking bin bottom, when the material generation arch camber of feed bin bottom, servomotor by the blanking bulkhead makes the feed screw revolution, it is upper and lower mobile to drive liner plate, the arching phenomenon of blanking bin middle and lower part material is eliminated, thereby prevented that effectively blanking bin from stopping up.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the utility model feed bin anti-block apparatus is arranged on the bottom liner plate 5 all around of blanking bin 2, the bottom surface of this liner plate 5 is provided with cylinder 8, the blanking bulkhead corresponding with this liner plate 5 is provided with the through hole 9 of strip, cylinder 8 on this liner plate 5 stretches out through hole 9 and is connected with feed screw 4, and this feed screw 4 is connected with the rotating shaft of the servomotor 3 that is arranged on the blanking bulkhead back side.Like this, when the material generation arch camber in the feed bin, make feed screw 4 revolutions, thereby drive liner plate 5 upper and lower the moving in the blanking bin 2, the arching phenomenon of feed bin middle and lower part material is eliminated, prevent that effectively blanking bin 2 from stopping up by servomotor 3.
