Abstract
The invention discloses a spiral conveyer which comprises a shell. A spiral shaft is rotationally arranged in the shell. A spiral blade is arranged on the spiral shaft. A blade generatrix of the spiral blade is composed of a straight line section and a bent section. The straight line section is close to the edge of the spiral blade, and the bent section is an arc section or parabolic section or hyperbola section. The straight line section is tangent to the bent section. The bent section is bent in the conveying direction. According to the spiral conveyer, by the adoption of the structure that the bent section is arranged on the blade generatrix, bulk material conveying efficiency can be effectively improved during vertical conveying; during horizontal conveying, conveying efficiency is improved, and meanwhile compensation can be achieved for deformation of the spiral shaft to a certain degree.
Description
Technical field
The present invention relates to conveyer field, particularly a kind of conveyor screw.
Background technology
Conveyor screw is used for continus convergence and falls apart shape bulk cargo, and existing conveyor screw Problems existing is, fed distance only can between 3 ~ 5 meters, and exceeding this length just needs to configure suspension bearing.And in the course of conveying of existing conveyor screw, there is the problem that transport efficiency is not high.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of conveyor screw, effectively can improve the transport efficiency of bulk cargo when vertical transport, when horizontal feed, can compensate the problem of screw shaft distortion to a certain extent.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of conveyor screw, comprise housing, screw shaft is rotating to be arranged in housing, screw shaft is provided with helicallobe, the blade bus of helicallobe is made up of linear portion and bending section, and linear portion is positioned at the position near helicallobe edge.
Described bending section is circular arc line segment, parabolic segment or hyperbolic line segment.
Described linear portion and bending section tangent.
The bending direction of bending section is towards throughput direction.
A kind of conveyor screw provided by the invention, by adopting the structure arranging bending section at blade bus, the transport efficiency of bulk cargo effectively can be improved when vertical transport, when horizontal feed, while raising transport efficiency, also can compensate the problem of screw shaft distortion to a certain extent.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of the blade bus of helicallobe in the present invention.
Fig. 3 is the structural representation of conveyor screw in prior art.
Fig. 4 is the structural representation of the blade bus of helicallobe in prior art.
The structural representation of Fig. 5 to be the blade bus of helicallobe be conveyor screw of full bending section.
The structural representation of Fig. 6 to be the blade bus of helicallobe be full bending section.
In figure: housing 1, screw shaft 2, helicallobe 3, blade bus 4, linear portion 41, bending section 42, the first component f1, the second component f2, thrust f3, the 3rd component f4, the 4th component f5, make a concerted effort f6.
Detailed description of the invention
A kind of conveyor screw, comprise housing 1, what housing 1 cross-sectional plane was conventional has circle or U-shaped, screw shaft 2 is rotating to be arranged in housing 1, screw shaft 2 is provided with helicallobe 3, the blade bus 4 of helicallobe 3 is made up of linear portion 41 and bending section 42, and linear portion 41 is positioned at the position near helicallobe 3 edge.
In horizontal feed process, the screw shaft 2 rotated makes helicallobe 3 pairs of bulk cargos generations away from the second component f2 of axis, the antagonistic force of this second component f2 makes bulk cargo provide supporting for helicallobe 3, thus can compensate the problem of screw shaft distortion to a certain extent.After tested, the effect of this supporting is relevant to the rotative speed of screw shaft 2, and when the rotative speed of screw shaft is higher, supporting power is larger.In the course of conveying of conveyor screw, the conveying of bulk cargo mainly rotates from helicallobe 3 thrust that produces and the combined result of friction force between bulk cargo and housing 1.Due to the effect of the second component f2, add friction force between bulk cargo and housing 1, and the first component f1 is vertically reduced, the edge of the more multidirectional helicallobe 3 of bulk cargo is concentrated, bulk cargo is avoided to followed by the rotation of helicallobe 3 and rotate, thus improve transport efficiency, under horizontal operating mode, under the equal same bulk cargo condition of rotating speed, improve 7.5% ~ 11% to carry the transport efficiency of total.In vertical transport operating mode, the action effect of the second component f2 and gravity, improves friction force between bulk cargo and housing 1 further, avoids bulk cargo followed by the rotation of helicallobe 3 and rotate, thus improve transport efficiency.Under vertical transport operating mode, under the equal same bulk cargo condition of rotating speed, improve 9.5% ~ 13% to carry the transport efficiency of total.
In preferred scheme, described bending section 42 is circular arc line segment, parabolic segment or hyperbolic line segment.Described linear portion 41 is tangent with bending section 42.The bending direction of bending section 42 is towards throughput direction.
After tested, the increase of transport efficiency is with hyperbolic line segment best results, and the effect of supporting power is better with parabolic segment effect, and the effect of circular arc line segment mediates.
The above embodiments are only the preferred technical solution of the present invention, and should not be considered as restriction of the present invention, and the embodiment in the application and the feature in embodiment, can combination in any mutually when not conflicting.The technical scheme that protection scope of the present invention should be recorded with claim, the equivalents comprising technical characteristic in the technical scheme of claim record is protection domain.Namely the equivalent replacement within the scope of this improves, also within protection scope of the present invention.
