For convenient for material cavity bottom be in suspended state, on the one hand can as described above by setting the second delivery pipe
140 can make the positive pressure gas flow of material generation eddy flow to provide, on the other hand can be by setting cavity bottom to convenient for object
Expect the structure to suspend.Illustrate two kinds of embodiments of the invention below.
First embodiment
As shown in Figure 1, the bottom of the feed bin 110 is enclosed construction to limit internal cavity, the second appendix 140 from
The upper direction cavity of cavity bottom provides barotropic gas.In this structure, since the bottom of feed bin 110 is enclosed construction, thus
Convenient for manufacturing and safeguarding, and ensure that bottom without external interface, avoids the problem of bin bottom leaks.
For convenient for material eddy flow, the bottom is continuous reclinate curve form, will pass through reclinate song
The flowing of face shape directing material.Wherein, continuous reclinate curved surface can be a part of spherical surface, ellipsoid etc..
Preferably, as shown in figure 4, the bottom has domed inner surface, material will be along domed interior table as a result,
Face towards on one side surround while bottom bottom it is mobile, so that material is along domed inner surface turn and is in suspended state.
For the turn for increasing material, the second appendix 140 setting are as follows: the positive pressure that second appendix 140 provides
Air-flow drives the material to form the eddy flow towards the bottom helical flow of the bottom.For this purpose, second appendix 140
It can be extended spirally in the bottom along the domed inner surface.Specifically, as shown in figure 3, second appendix 140
It may include the first pipeline section 140a being sequentially connected end to end and the second pipeline section 140b, the first pipeline section 140a from the feed bin
110 top verticals extend, and the second pipeline section 140b is extended spirally along the domed inner surface.
Wherein, the feed bin 110 may include the main part being set to above the bottom, and the main part has cylinder
The inner surface of shape, the columnar cross section is consistent with the domed bottom surface, and the first pipeline section 140a is along the circle
The bus of tubular extends, i.e. the inner wall that the first pipeline section 140a is close to main part extends vertically, to arrange and avoid material in chamber
Intracorporal eddy flow.
Furthermore it is preferred that second appendix 140 may include the multiple described of the different height positioned at the cavity
Outlet 141, to increase the agitation to material in cavity, so that eddy flow is more readily formed in material.
It is furthermore preferred that the outlet 141 is located at the middle part of the short transverse of the cavity hereinafter, to ensure material towards chamber
Body bottom eddy flow.For example, in the embodiment shown in figure 1, the second appendix 140 may include positioned at cavity middle and lower part and
Two positioned at cavity bottom export 141.Wherein, the outlet 141 positioned at the middle and lower part of cavity can increase the intracorporal material of chamber
Turn, so that suspended state is presented in material.Positioned at the outlet of cavity bottom, 141 one side can cooperate the outlet 141 of middle and lower part
Make material turn, on the other hand outlet can be looked for cavity bottom movement with directing material, so as in cavity bottom namely segment
Assemble and sent out from material efferent duct 150 in the bottom of shape.As shown in Fig. 2, Flow of Goods and Materials track is spiral shape.
Wherein, second appendix 140 may include the inner surface from the first pipeline section 140a along the main part
Circumferentially extending third pipeline section 140c and positioned at the outlet 141 of the end of the third pipeline section 140c, to pass through third
The outlet 141 of pipeline section 140c provides the circumferential positive pressure gas flow along main body, to increase the intracorporal material turn of chamber.
Of course, it is possible to multiple third pipeline section 140c are arranged in the extending direction along the first pipeline section 140a in main part, it can also
With the extending direction along the first pipeline section 140a, multiple second pipeline section 140b are set in bottom.
By present embodiment, barotropic gas moves the bottom spiral for driving material towards the spherical inner surface of bottom
It is dynamic, for be located on the center line of the eddy flow convenient for one end of outside feeding, the material efferent duct 150 and close bottom most
Lower end setting.In addition, sending out suffered resistance from material efferent duct 150 to reduce material, the material efferent duct 150 prolongs vertically
It stretches.
Second embodiment
