Abstract
The impeller type coal feeder 1 is characterized in that a feeding side and a discharging side are separated from each other by impeller blades, 2 is an automatic avoiding mechanism consisting of a movable door connecting rod and a spring, and an impeller and a shaft can integrally slide on a slide way in a translation mode, so that the phenomenon of blocking of large-diameter particles is fundamentally solved, and the problem that conveying media of various coal feeders used at present can automatically pass through without being controlled by the coal feeder is effectively solved.
Description
The utility model relates to a kind of vane type feeder, belongs to the coal mine machinery field.
The coal feeder of using has fixed disc formula feeder now, reciprocating type feeder, and the Electromagnetically vibrating feeder, the common issue with that these several feeders exist is that it is continuous being input to discharging opening output from feeding mouth during pumped (conveying) medium.As run into when containing on a small quantity than the major diameter particle, pumped (conveying) medium is stuck in impassabitity in the feeder; Simultaneously feeding mouth and discharging opening are osed tops not, if the pumped (conveying) medium aqueous ingredients is higher, thereby pumped (conveying) medium is not controlled and voluntarily by causing device damage by feeder.
The purpose of this utility model is to solve to run into that the major diameter granule medium is unlikely to be stuck in the feeder, and when running into medium and containing a large amount of moisture content, pumped (conveying) medium is unlikely not to be subjected to feeder control and to pass through voluntarily.
The purpose of this utility model is achieved in that 1 is with impeller vane pan feeding side and discharging to be kept apart soon eventually, and this is not subjected to feeder control with regard to the frequent pumped (conveying) medium of various feeder that has fundamentally solved present use and the problem passed through voluntarily.The 2nd, dodge mechanism automatically by what dodge gate connecting rod and spring were formed, being provided with of this mechanism solved the major diameter particle and has been stuck in unpassable phenomenon in the feeder, and the 3rd, feeding mouth has just been stopped the phenomenon that the major diameter particle is stuck in feeding mouth than the width of impeller is little at feeding mouth.
Fig. 1 vane type feeder front elevation
Fig. 2 vane type feeder structural representation
The concrete structure and the working process of this machine are provided in conjunction with the embodiments by the following drawings: (1) is support body shown in the figure; (2) be dodge gate; (3) be impeller; (4) be connecting rod; (5) be slideway; (6) be spring; (7) be feeding mouth; (8) be discharging opening; (9) be axle.
Main frame body is a column type cylindrical shell, and it comprises feeding mouth 7, and discharging opening 8 and dodge gate 2, dodge gate 2 are faces of cylinder of cylindrical tube 1/4th, and a side is connected with hinge with main frame body, and opposite side links to each other with connecting rod 4; Impeller 3 is made up of four blades and wheel, be fixed on the axle, support with antifriction-bearing box at axle 9 two ends, and frame is on slideway 5, and impeller and axle integral body can translation glidings on slideway, power is by the rotation of axle impeller, blade is made of the arc surface with the cylindrical shell same radius, and its effect 1 is to isolate pan feeding side and discharging side's sealing medium that send, and the 2nd, driving medium movable connecting rod one end and plain bearing housing are hinged, the other end and dodge gate are hinged, make dodge gate and two adjacent blades constitute an enclosure space; Slideway 5 is to be welded by two parallel channel-section steels, for bearing seat translation thereon, has the connecting rod 4 of band spring 6 in the slideway 5, and spring 6 is used for impeller and dodges resetting behind the bulky grain medium; Feeding mouth is that the quadrntnt cylinder is put the coal mouth with coal bunker and communicated; Discharging opening also is the quadrntnt cylinder, and the blade pumped (conveying) medium depends on deadweight to fall.
Working process is such: 1 is proportional when being no more than 10% diameter and being not more than 500 millimeters particle when containing in the pumped (conveying) medium, the drive mechanism impeller rotation of device, when particle enters impeller with blade, by impeller rotating blade extruding major diameter particle, make impeller be subjected to a power to the discharging opening direction, when this power during greater than the roof pressure power of spring, paddle shaft retreats along slideway, and connecting rod jack-up dodge gate bulky grain medium falls with sliding to discharging opening under the rotary blade.After the bulky grain medium passed through, under the thrust of spring, the impeller reach resetted, and connecting rod drives dodge gate and also sets back, and carries out normal feeding.
2, in pumped (conveying) medium, contain and proportionally be no more than 10%, when maximum gauge is no more than 400 millimeters particle, impeller rotates under the propulsive effort effect, medium is because from reentering feeding mouth, impeller with rotation is sent by occluding surface, because solid particle medium has incompressibility, thereby design impeller length is bigger than feeding mouth length.Can solve like this when medium complete closed that two adjacent vanes rotations is brought into, unlikelyly be full of enclosure space and stuck phenomenon takes place.
3, when the particle media water content more, be liquid when properties of flow, vane type coal supply blade is kept apart pan feeding side and discharging side fully, make the medium that is transported be split into quadrntnt cylindricality volume and constantly export, the problem of passing through voluntarily thereby the pumped (conveying) medium the problem includes: of having avoided the various feeder problem of present use effectively is not subjected to feeder control.
4, the impeller hand of rotation be anticlockwise direction rotation but when running into the major diameter granule medium dodge gate near the one side at connecting rod position lift allow the major diameter granule medium by after reset.
The power of this device can drive with windmotor, little, the easy installation of windmotor volume, reliable operation.Also available motor driving, belt-driving, should be provided with belt stretcher this moment, is beneficial to impeller and retires.The rotating speed of impeller should be in 10 rev/mins.
5, compare with existing various feeders:
1, with impeller vane pan feeding side and discharging are kept apart soon eventually, the various feeder that has fundamentally solved present use takes place often that pumped (conveying) medium is not subjected to feeder control and the problem passed through voluntarily.
2, driving medium motion.Connecting rod one end and plain bearing housing are hinged, and the other end and dodge gate are hinged; Make dodge gate and two adjacent blades constitute an enclosure space; When carrying the major diameter granule medium, bearing seat can move along slideway is parallel.Spring is used for resetting after impeller avoids allowing the major diameter granule medium export.
