Abstract
The utility model discloses a star-shaped feeding device for preventing blockage. The device comprises a shell, a rotor and blades, wherein a feeding hole is formed on the upper part of the shell; a discharge hole is formed on the lower part of the shell; the blades are uniformly distributed on the rotor; a conveying storage silo is formed between two adjacent blades; and an offset distance S is formed between a center line of the feeding hole and an axis of the rotor. The utility model has the advantages that: the center line of the feeding hole deviates from the axis of the rotor, and the torque of a motor for driving the rotor to rotate is reduced by utilizing self gravity of materials to be conveyed; and therefore, the star-shaped feeding device is difficultly blocked, and a star-shaped feeder smoothly and uniformly feeds materials.
Description
Technical field
The utility model relates to the stifled star charging gear of a kind of anti-sticking.
Background technology
In fields such as electric power coal-burning boiler, waste incineration, cement, flue gas desulfurization, all relate to the conveying of granular material.When convey materials, too much cause difficulty of transportation for fear of the material that gets into pipeline, the bin outlet place that is everlasting is provided with star feeder, realizes even feeding, but therefore also usually runs into the stifled problem of star feeder card.Like Fig. 1: the desulfurizing agent agstone in flue gas desulfurization is transported to the star feeder of slurries case from the powder storehouse, and when the pumping board valve opening of star feeder top is bigger, agstone directly acts on the star feeder; When the star feeder of stopping transport opens again; Often rotor is blocked, and the moment of torsion of motor can't rotate star feeder, and the top material is many more heavy more; It is big more that star feeder stops up possibility, moves then more difficult.The operations staff uses weights such as hammer, iron staff always and knocks the star feeder housing, with the mode of expectation with vibration, makes the interior material of rotor loosening, reduces moment of torsion, realizes that star feeder runs well, and has brought very big trouble to ordinary production.
The utility model content
The purpose of the utility model is to provide a kind of anti-sticking stifled star charging gear, can effectively solve the problem of blocking easily when existing star charging gear starts.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: the star charging gear that a kind of anti-sticking is stifled, comprise housing, rotor, blade, and housing top has charging aperture; Said lower housing portion has discharging opening; Be evenly distributed with blade on the said rotor, form one between said two adjacent vanes and carry storage bin, form offset distance S between the center line of said charging aperture and the axis of rotor.
Preferably, the direction of rotation of said rotor is consistent with the disalignment direction of charging aperture; Effectively reduce Motor torque, make the convenient whereabouts of material.
Preferably, distance is zero between the axis of the center line of said discharging opening and rotor; Be convenient to dock with the slurries case.
Preferably, said conveying storage bin has six to ten; Can carry preferably.
Compared with prior art; The utility model has the advantages that: the axis of the disalignment rotor of charging aperture, utilize the gravity of convey materials self, alleviate the Motor torque that drives rotor rotation; It is stifled to make the star charging gear be difficult for card, realizes the smooth and easy even feeding of star feeder.
Description of drawings
Fig. 1 is the structural representation of existing star charging gear;
Fig. 2 is the structural representation of the stifled star charging gear of a kind of anti-sticking of the utility model.
The specific embodiment
Consult the embodiment of Fig. 2 for the stifled star charging gear of a kind of anti-sticking of the utility model, the star charging gear that a kind of anti-sticking is stifled comprises housing 2, rotor 3, blade 6; Housing 2 tops have charging aperture 1; Said housing 2 bottoms have discharging opening 5, are evenly distributed with blade 6 on the said rotor 3, form one between said two adjacent vanes 6 and carry storage bin 4; Form offset distance S between the axis of the center line of said charging aperture 1 and rotor 3; The direction of rotation of said rotor 3 is consistent with the disalignment direction of charging aperture 1, and distance is zero between the axis of the center line of said discharging opening 5 and rotor 3, and said conveying storage bin 4 has six to ten.
Offset distance S is less than rotor 3 radiuses, and when the agstone in powder storehouse, top acted on charging gear through charging aperture 1, its gravity just acted on the blade 6; Make rotor 3 that the trend that is rotated down arranged, the top material is heavy more, and the rotation trend of rotor 3 is big more; Can reduce the used torque of motor more, the direction of motor-driven rotor 3 rotations is consistent with material gravity effect rotor 3 rotation trend, and material is stored in temporarily and carries in the storage bin 4 simultaneously; When it turns to discharging opening 5; Limestone material falls within the slurries case because of gravity, and said process all carries out in housing 2 inside, and material is not revealed and feed is smooth and easy does not stop up.
The above is merely the specific embodiment of the utility model; But the technical characterictic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
