Description
Technical field
The present invention relates to a kind of rotary feeder, particularly a kind of rotary feeder of low speed continuous uniform feed.
Background technology
Rotary feeder claims again rotovalve or air sealer, has lock wind performance, can resistance to certain pressure reduction.Rotary feeder can carry out material dosing feed, is a kind of key equipment in air-transport system.Conventionally the structure of rotary feeder is made up of parts such as housing, end cap, impellers, when work, impeller rotates in columnar housing, material falls between blade set impeller in space from top hopper by self gravitation effect, material is discharged to the rotation of impeller the discharging opening that lower housing portion arranges, discharged by discharging opening, or at the bottom of discharging opening connecting tube, the material of whereabouts mixes with air-flow in pipeline, under the effect of pressure and air-flow, arrives destination by pipeline.
Existing rotary feeder is in the process of feed, and because discharging opening is generally squarely, the material of discharge is to be interrupted discontinuously, and rotating speed is lower, and discountinuity is more obvious.In the process of high speed rotary, interruption interval is shorter, conventionally can be considered continuous feeding.In the time that low speed turns round, interruption interval is larger, often can not meet the requirement of user to degree of uniformity.And how to realize the continuous uniform feed of rotovalve, be unsolved technical barrier always.
For having pressure reduction and needing the operating mode of continuous uniform feed mostly to adopt at present the combination of screw feeder or disk feeder and rotovalve to realize, screw feeder or disk feeder complete continuous uniform feed, rotary feeder completes lock wind function, two kinds of device combination costs are high, reliability is low, therefore, design and development one had both had lock wind energy power, and product that again can continuous uniform feed is necessary.
Summary of the invention
The invention provides a kind of rotary feeder of low speed continuous uniform feed, object is that the discharging opening that solves existing rotary feeder adopts squared design, exists in the process of low speed feed, and discountinuity discharge is obvious, problem that cannot continuity even feeding.
In order to address the above problem, the technical solution adopted in the present invention is: a kind of rotary feeder of low speed continuous uniform feed, comprise housing, end cap and rotor, described housing top is provided with inlet point, bottom is provided with discharging opening, the two ends of housing are provided with end cap, end cap is secured by bolts on housing, described rotor is horizontally installed in enclosure interior, described rotor comprises impeller and rotating shaft, rotating shaft is arranged at the centre of impeller, stretch out outside end cap one end of described rotating shaft, it is characterized in that, the blanking limit of described discharging opening is a hypotenuse, the angle that described hypotenuse and the central axis of rotating shaft are angled.
The blanking limit of described discharging opening is a straight line hypotenuse.
The blanking limit of described discharging opening is a curve hypotenuse.
The opening shape of described discharging opening is set to triangle, trapezoidal or parallelogram.
The invention has the beneficial effects as follows:
The present invention has overcome the existing technological deficiency of current existing rotary feeder, has solved common rotary feeder in the time of low speed rotation, and feed discountinuity is obvious, cannot realize the problem of continuity even feeding.In addition, it also has the performance of withstand voltage difference, has ensured that material is having continuous uniform feed under differential pressure conditions, and it has, and reasonable in design, cost are low, good stability, feature that reliability is high.

Detailed description of the invention
For clearly demonstrating the technical characterstic of this programme, below by a detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Fig. 1-6, the rotary feeder of a kind of low speed continuous uniform of the present invention feed, it comprises housing 1 and rotor 2, described housing 1 top is provided with inlet point 3, bottom is provided with discharging opening 4, the two ends of housing 1 are provided with end cap 5, and end cap 5 is secured by bolts on housing 1, and described rotor 2 is horizontally installed in housing 1 inside, described rotor 2 comprises impeller 21 and rotating shaft 22, rotating shaft 22 is arranged at the centre of impeller 21, and stretch out outside end cap 5 one end of described rotating shaft 22, for connecting Power Drive Unit.
Outstanding improvement of the present invention is the discharging opening 4 arranging on rotary feeder housing, and the blanking limit 41 of described discharging opening 4 is a straight line hypotenuse or curve hypotenuse, the angled angle of central axis of described hypotenuse and rotating shaft 22.The opening shape of described discharging opening 4 can be set to triangle, trapezoidal or parallelogram as required.But the opening shape of discharging opening is not only confined to shape described above, opening shape can be revised as other shape according to powdery row material characteristic, this opening shape needs only the angled angle of central axis that meets a limit and rotating shaft 22, and extends to gradually offside since a side.The discharging opening 4 that is arranged on like this process middle shell 1 that impeller 21 rotates can ensure the continuously uninterrupted discharging simultaneously of more than two impeller hopper simultaneously, thereby has ensured the continuity of discharging opening 4 dischargings.
When work, in the time that discharging opening 4 is passed through in the rotation of impeller hopper, the interior material of impeller hopper is first contended stepping by the initiating terminal one of discharging opening 4 and is entered discharging opening, and material continuous uniform is discharged, until impeller hopper, through discharging opening 4 another angle terminals, completes once the discharge process of this correspondence impeller hopper.In this process, along with the rotation of impeller, material in this impeller hopper is discharged after a part, and impeller hopper below enters 4 one jiaos of discharging openings and starts discharging, now, at impeller hopper above gradually in discharge, impeller hopper also starts discharge gradually below, forms the discharging simultaneously of more than two impeller hopper, by this stacked system, blanking before and after impeller hopper is linked up, make feed more even, even if also can realize continuous uniform blanking for the bad material of flowing power like this.
In order to further illustrate the stability of discharging opening discharging of the present invention, be further described below in conjunction with the discharge characteristic curve of material:
Fig. 7 is the discharge characteristic curve of drawing in the discharge situation of low speed feed according to common rotary feeder, and as can be seen from the figure, the in the situation that of low speed feed, discharge discountinuity is obvious.Fig. 8 is the discharge characteristic curve of rotary feeder of the present invention in the time of the better material of flow behavior, and as can be seen from the figure, for the material of good fluidity, it discharges characteristic is the straight line of a level substantially.
As shown in Fig. 9,10, discharge characteristic curve when Fig. 9 single impeller hopper discharge that is the present invention in the time of the bad material of flow behavior; Figure 10 is the present invention in the time of the bad material of flow behavior and has two with feeding groove discharge characteristic curve when discharge simultaneously, can be learnt by Fig. 9 and the shown discharge characteristic curve contrast of Figure 10, when having plural impeller hopper simultaneously when discharge, discharge characteristic between impeller hopper has the stack that partially overlaps, for the bad material of flowing power, can alleviate by this stack the fluctuation of feed quantity, realize continuous uniform blanking.
The above is the preferred embodiment of the present invention, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, and these improvements and modifications are also regarded as protection scope of the present invention.
