Abstract
The invention discloses a star-like unloader comprising a housing, an impeller shaft and an impeller. The upper and lower ends of the housing are provided with a feed hole and a discharge hole respectively. The impeller shaft driven to rotate by a drive device is disposed within the housing. The impeller fixedly sleeves the impeller shaft; blades of the impeller skew off the axis of a hub at a certain angle. Two scrapers are arranged on the inner wall of the housing on two radial sides of the axis of the hub of the impeller. When the blades of the impeller rotate to the corresponding parts of the scrapers, gaps are reserved between the front edges of the scrapers and the front edges of the blades of the impeller. Linear shearing of materials is converted into point shearing, so that shearing force is decreased and the impeller is effectively prevented from jamming.
Description
Technical field
The present invention relates to a kind of star-like discharger.
Background technology
Star-like discharging device device is the major equipment of dusting equipment ash discharge, air-supply and miscellaneous equipment feed, star-like discharging device is applicable to granular material and granulated material, its compact conformation, handsome in appearance, easy to use, and smooth running is the industrial sector widespread uses such as environmental protection, metallurgy, chemical industry, grain, food.Blade edge and paddle shaft line parallel on conventional star-like impeller of discharger, material dropping process and vane rotary carry out simultaneously, impeller and casing just have an effect to material cutting, in material, mix while having cotton-shaped or velvet-like material especially, this phenomenon is particularly evident, its cutting mode is linear shearing, shearing force is larger, so have the vexed sound of " bang bang " during machine operation, when serious, can cause discharger to stop up, occur these situations normally expanded motor power so that its pressure sheared, can aggravate the blade wear of impeller like this, if removed and housing is opened, have a strong impact on again work efficiency.
For above-mentioned technical matters, be still necessary to invent a kind of star-like discharger stopping up that is not easy to produce.
Summary of the invention
The present invention, in order to overcome prior art defect, has invented a kind of star-like discharger, has simple in structurely, can reduce to cut shearing and prevent the advantages such as resistance is stifled.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of star-like discharger, it comprises: Shang Xia one, two ends are respectively arranged with the housing of inlet point and discharging opening, one is arranged in described housing and the paddle shaft rotating by an actuating device driving, wherein: a fixed cover is located at the impeller on described paddle shaft, the blade of described impeller and the hub axis angle of setovering; Described inner walls is fixedly installed respectively two scraper plates corresponding to the radially both sides of the hub axis of described impeller, when the blade rotation of described impeller arrives the position corresponding with described scraper plate, between the blade forward position of the forward position of described scraper plate and described impeller, leave gap.
Preferably, described scraper plate forward position is parallel to the axis of described paddle shaft.
Preferably, described scraper plate forward position is provided with blade.
Preferably, the blade of described impeller is at least three, and evenly decile is arranged on wheel hub outer wall circumference.
Preferably, the blade quantity of described impeller is six.
Preferably, the angle of the blade of described impeller and hub axis biasing is 2-8 °.
Preferably, when the blade rotation of described impeller arrives the position corresponding with described scraper plate, the gap, blade forward position of described scraper plate forward position and described impeller is 0.2-0.5mm.
The present invention compared with prior art, the beneficial effect having is: by an angle that the blade of impeller and hub axis are setovered, and in housing, be provided with the scraper plate corresponding with impeller, between blade and scraper plate, to the cutting mode of material, be point type cutting, reduce cutting force, reduce noise, and scraper plate forward position is provided with blade, the obstruction that can effectively prevent solid accumulation and cause, energy efficient, raises the efficiency.

The specific embodiment
Referring to accompanying drawing and in conjunction with the specific embodiment, further describe the present invention, to make those skilled in the art can implement according to this with reference to specification sheets word, but be to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, " left side ", " right side " all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the present invention.
Embodiment
As shown in Figure 1, a kind of star-like discharger, comprise: housing 1, paddle shaft 6, impeller 2, scraper plate 4 and actuating device (figure does not look), wherein: the upper end of housing 1 is provided with inlet point 3 and its lower end is provided with discharging opening 5, paddle shaft 6 is arranged in housing 1 in rotating mode, and its one end stretches out in outside housing 1 and is connected with actuating device, actuating device is comprised of motor and retarder, and one end that the mouth of retarder projects outward from the housing with paddle shaft 6 is connected the rotation with drives impeller axle 6.As shown in Figure 2, impeller 2 comprises blade 22 and wheel hub 21, blade 22 is six and is uniformly distributed on the outer wall circumference of wheel hub 21, and every blade 22 is with respect to axis bias one angle of wheel hub 21, both angles are 6 °, and impeller 2 is located on paddle shaft 6 to be driven in the interior rotation of housing 1 by paddle shaft 6 by wheel hub 21 fixed covers.Housing 1 inwall is fixedly installed respectively two scraper plates 4 corresponding to the radially left and right sides of wheel hub 21 axis of impeller 2, two scraper plate 4 forward positions be parallel to paddle shaft 6 axis so that the axis of two scraper plate 4 forward positions and impeller 2 be parallel to each other and keep at grade, scraper plate 4 forward positions are also provided with blade 41, when the blade 22 of impeller 2 turns to the position corresponding with scraper plate, between blade 22 forward positions and blade 41, leave the gap of 0.3mm so that impeller 2 can be in the interior rotation of housing 1, avoid again a large amount of materials directly from gap, to drop, affect the stability of feeding.
When the present invention works, material continues from inlet point 3, to drop to discharging opening 5 equably under the effect of impeller 2, and drop in process, because blade 22 is with respect to wheel hub 21 biasing one angles, an angle so the blade 41 in blade 22 and scraper plate 4 forward positions is also setovered, between blade 41 on blade 22 and scraper plate 4 forward positions, material is carried out cut to cut as point type cut and cut, cutting force is little, the noise producing is also little, in material, mix while having cotton-shaped or velvet-like material or impurity, under blade 41 cuttings in scraper plate 4 forward positions, cotton-shaped or velvet-like material or impurity can brokenly also drop out from discharging opening 5 smoothly, thereby effectively avoid cotton-shaped or velvet-like material or impurity jam to cause resistance to block up, cause that cutting the power of cutting increases between impeller 2 and housing 1, the wearing and tearing of aggravation blade 22, and can reduce the clearing times to equipment, easy cleaning work, work efficiency is high.
Disclosed is above only specific embodiments of the invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
