Embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.

Shown in Figure 2, the utility model provides a kind of connecting tube for powder uniform distribution, including tube body 1, poly- material Funnel 2 and homogenizing device 4.Tube body 1 is bolted in the lower end of compensator, and the top of the inner side of tube body 1 is provided with poly- funnel 2, tube body 1 The lower part of inner side is provided with homogenizing device 4, also, spaced apart between poly- funnel 2 and homogenizing device 4.Homogenizing device 4 For making material uniformly convey downwards.

Shown in Figure 3, homogenizing device 4 includes heap expects pipe 42, and heap expects pipe 42 is located at the center of tube body 1.Poly- material leakage The lower port of bucket 2 is just opposite with the upper end of the heap expects pipe 42 of homogenizing device 4, and poly- funnel 2 is spaced a spacing with heap expects pipe 42 From.When material conveys downwards, material is dropped into heap expects pipe 42 by poly- funnel 2, and from the surrounding of heap expects pipe 42 to downslide Fall, to play the purpose of dispersed material, structure setting is simple.

In the downside of tube body 1, feed bin or other devices are set, when material is conveyed downwards by compensator, when being delivered to tube body 1, Material continues to be delivered to homogenizing device 4 downwards via the poly- funnel 2 in tube body 1, and is delivered to next feed bin by homogenizing device 4 Or other processing equipments.

In a specific embodiment, heap expects pipe 42 is column structure, and its upper part has a concave surface, the top of concave surface it is straight Footpath is identical with the diameter of cylinder；Part below the concave surface of heap expects pipe 42 is entity or hollow-core construction, i.e. the lower face of concave surface with Part between the tube wall of heap expects pipe 42 can be entity structure or hollow-core construction.Specifically, the depth of concave surface is heap 0.9~0.95 times of 42 radius of expects pipe.The depth of concave surface is maintained at rational scope, be both unlikely to make the material for falling into concave surface Excessively, and ensure that material can be stacked into certain altitude, easy to the downslide of material.

When material is conveyed downwards by poly- funnel 2, material is dropped into the concave surface on 42 top of heap expects pipe, and in concave surface Accumulation.Since heap expects pipe 42 is located at the center of tube body 1, with reference to the characteristic of material, material is accumulated in concave surface until being higher than windrow The top surface of pipe 42 and form the material heap of a vertebral body structure, the material subsequently fallen into is under the effect of gravity along the periphery of material heap Slide downwards, and continue to move downward by the surrounding of heap expects pipe 42 respectively, material is uniformly conveyed downwards, without only Slid toward a direction, make material skewness.

In another specific embodiment, in the concave surface of the extended line on the inclined-plane of poly- funnel 2 Jing Guo heap expects pipe 42 Heart position.Due to spaced apart between poly- funnel 2 and homogenizing device 4, and homogenizing device 4 is located at the centre bit of tube body 1 Put, adjust the spacing between poly- funnel 2 and homogenizing device 4 to appropriately distance, pass through the delay line on the inclined-plane of poly- funnel 2 Cross the center of concave surface.

When conveying downwards during material is by poly- funnel 2, due to the effect on poly- 2 inclined-plane of funnel, material is to tube body 1 Center conveys, and partial material is directly uniformly slid downwards by the surrounding of heap expects pipe 42；Partial material drops into heap expects pipe 42 Concave surface in, material is formed in the concave surface of heap expects pipe 42 after material heap uniformly to be slid to the surrounding of heap expects pipe 42 again, to reach The purpose of uniform feeding.

Shown in Figure 3 in another specific embodiment, homogenizing device 4 includes demarcation strip 41, heap expects pipe 42 and outer Wall 43.Heap expects pipe 42 is arranged on the center position of the inner side of outer wall 43, and demarcation strip 41 is vertically provided at heap expects pipe 42 and outer wall 43 Between, and fitted closely respectively with heap expects pipe 42 and outer wall 43.Demarcation strip 41 at least two, by heap expects pipe 42 and outer wall 43 Between section be separated into two or more independent sections, equidistant independent section is preferably separated into, so that material is uniform Conveying downwards.Specifically, it is connected between demarcation strip 41 and heap expects pipe 42 using welding manner；Adopted between demarcation strip 41 and outer wall 43 It is connected with welding manner；Outer wall 43 is hollow ringwall structure, is connected between outer wall 43 and tube body 1 using welding manner, with close Fit in the inner side of tube body 1.Further, the ratio of the internal diameter of the outside diameter of heap expects pipe 42 and outer wall 43 is maintained at 1:3 to 1:3.5 Between.

In another specific embodiment, homogenizing device 4 includes demarcation strip 41 and heap expects pipe 42.Heap expects pipe 42 is arranged on The center position of the inner side of tube body 1, demarcation strip 41 is vertically provided between the inner wall of heap expects pipe 42 and tube body 1, and demarcation strip 41 Fitted closely respectively with heap expects pipe 42 and the inner wall of tube body 1.Demarcation strip 41 at least two, by heap expects pipe 42 and tube body 1 it Between section be separated into two or more independent sections, be preferably separated into equidistant independent section so that material uniformly to Lower conveying.Specifically, it is connected between demarcation strip 41 and heap expects pipe 42 using welding manner；Used between demarcation strip 41 and tube body 1 Welding manner is connected.Further, the ratio of the internal diameter of the outside diameter of heap expects pipe 42 and tube body 1 is maintained at 1:3.1 to 1:3.6 it Between.

Shown in Figure 2, in another specific embodiment, it is fixed to be provided between poly- funnel 2 and homogenizing device 4 Away from ring 3, distance collar 3 and the inner wall of tube body 1 fit closely.Specifically, distance collar 3 is hollow and thin-walled pipe structure, is mainly used for propping up Support poly- funnel 2, and the distance between fixed poly- funnel 2 and homogenizing device 4.

It is understood that the height of distance collar 3 is reasonable according to the spacing demand between poly- funnel 2 and homogenizing device 4 Set, to meet demand of the inclined-plane extended line of poly- funnel 2 by concave surface center.

A kind of connecting tube for powder uniform distribution of the utility model, including the tube body 1 of compensator lower end is connected to, Top in tube body 1 is provided with poly- funnel 2, and the lower part in tube body 1 sets homogenizing device 4, the extension on poly- 2 inclined-plane of funnel Line passes through the center of the concave surface of homogenizing device 4, in order to surrounding slide downward of the material along homogenizing device 4, so as to reach uniform The purpose of feeding.

Finally, the method for the utility model is only preferable embodiment, is not intended to limit the protection of the utility model Scope.Where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on, should be included in Within the scope of protection of the utility model.
