Abstract
The utility model discloses a multistage winnower. The multistage winnower comprises a horizontal cylindrical housing. An air inlet and an air outlet are respectively arranged on the front end and the rear end of the housing. A material distributing opening is arranged on the top part of the front part of the housing. The multistage winnower is characterized in that a plurality of impellers arranged along cross sections of the housing are installed in the housing, the impellers divide the housing into a plurality of segments in the transverse direction, and a material receiving hopper is arranged on the lower part of each segment of the housing. According to the utility model, the winnower provided with the above structure adopts multistage impellers for sorting instead of a gravity screening mode employed by an existing winnower. Multistage refined sorting and one-time material discharging are realized. By adjusting the rotating speeds of the impellers, the screened granularity can be adjusted. The multistage winnower has no special requirements on the physical properties of the material itself, such as the humidity, so that the multistage winnower is wide in applicability.
Description
Technical field
The utility model relates to a kind of winnowing machine.
Background technology
winnowing machine is a kind of equipment that utilizes air-flow convey materials to screen.Existing winnowing machine comprises the tubular shell of horizontal positioned, and housing front and back end is respectively arranged with air inlet and air outlet.Housing bottom is axially provided with some recovering hoppers.In the time of work, wind enters from air inlet, and material is put into housing by the charging aperture of housing front top simultaneously.Under the effect of air-flow, the material of Different Weight falls into different recovering hoppers, reaches the object of sorting.But because the operating mode in airflow field is difficult to evenly, the condition of particle surface is also inconsistent, the windward side in floating constantly changes and causes precision not high.And the physical characteristics such as humidity to material itself also there are certain requirements, applicability is not high.
Summary of the invention
For the technical problem of above-mentioned existence, the utility model provides a kind of multilevel winnowing machine, and its screening precision is high, low to the character requirement of material own, is applicable to the selected of material.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
, comprising the tubular shell of horizontal positioned, housing front and back end has air inlet and air outlet; Housing front top is also provided with cloth mouth; It is characterized in that: the impeller that several arrange along housing cross section is installed in described housing; Impeller is laterally divided into some sections by housing, and every piece housing bottom is all provided with recovering hopper.
As a kind of improvement, described impeller comprises rotating shaft and is fixed on the blade in rotating shaft; Described rotating shaft is coaxial with housing, described blade and shaft parallel.Can avoid in housing, producing eddy flow with the blade of shaft parallel, reduce noise, reduce the wearing and tearing of material to blade and inner walls.
As a kind of, further improve, the windward side of described blade is the conical surface.Further reduce the wearing and tearing of material to blade.
As another kind, improve, described housing rear end adds dust arrester, on the housing of described dust arrester below, is provided with dust discharging port.After stock grading, in the air-flow of remainder or with certain dust, the dust arrester arranging by housing rear end, can purify air-flow, prevents from polluting.
As another kind, improve, on described housing, be provided with some observation panels of opening or close.Conveniently check the situation of enclosure interior.
As a kind of preferred, described impeller is two that front and back arrange.Two impellers are divided into three sections by housing, and material also can be divided into carse, medium and small Three Estate in screening.Can either reach the selected of a plurality of grades, be unlikely to again to screen line draw long after, the gravity of material is had an effect.
As a kind of preferred, described impeller is that stainless steel is made.Be anticorrosion wear-resisting again, extended complete machine service life.
Usefulness of the present utility model is:
The winnowing machine with said structure, has abandoned the gravity screening mode that existing winnowing machine adopts, and utilizes multi-stage impeller to carry out sorting.Can be multistage selected, a discharging.By regulating the rotating speed of impeller, can adjust the granularity of wanting screening.And the physical propertys such as humidity to material itself do not have specific (special) requirements, and applicability is wide.The utility model is simple in structure, and effect is remarkable, and economy is practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 housing, 2 air inlets, 3 air outlets, 4 cloth mouths, 5 recovering hoppers, 6 impellers, 7 blades, 8 rotating shafts, 9 dust arresters, 10 dust discharging ports.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1:
The utility model comprises the tubular shell 1 of horizontal positioned, and housing 1 front and back end has air inlet 2 and air outlet 3; Shell 1 body front top is also provided with cloth mouth 4; The impeller 6 that several arrange along housing 1 cross section is installed in described housing 1; Impeller 6 is laterally divided into some sections by housing 1, and every piece housing 1 bottom is all provided with recovering hopper 5.Described impeller 6 comprises rotating shaft 8 and is fixed on the blade 7 in rotating shaft 8; Described rotating shaft 8 is coaxial with housing 1, and described blade 7 is parallel with rotating shaft 8.The windward side of described blade 7 is the conical surface.Described housing 1 rear end adds dust arrester 9, on the housing 1 of described dust arrester 9 belows, is provided with dust discharging port 10.On housing 1, be provided with some observation panel (not shown)s of opening or close.Described impeller 6 is two of front and back setting, and impeller 6 is preferably made by stainless steel.
In the time of work, utilize blower fan to originate for winnowing machine provides wind-force, air-flow enters from air inlet 2, from air outlet 3, discharges.Powder is poured out housing 2 from cloth mouth 4, starts the impeller 6 by driven by motor.Material from the end motion backward of housing 1 front end, is discharged from recovering hopper 5 after the material that granularity is large collides that impeller 6 is rear and rebounded under the effect of air-flow, and the material that granularity is little enters next stage housing 1 through impeller, by that analogy.By regulating the rotating speed of impeller 6, can screen as required the material of variable grain degree.Every grade of impeller 6 is adjusted to different rotating speeds, makes whole winnowing machine once can filter out the material of multiple granularity, very easy to use.
Existing winnowing machine is all to utilize the gravity of material self to screen, and not only accuracy is not high, and requires also higher to material itself.And the disclosed winnowing machine of the utility model utilizes impeller 6 rotating speeds to screen, accuracy and adaptability all improve greatly, and once can filter out varigrained material, have greatly improved production efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
