Fig. 2 is an embodiment's of the connecting tube that is used to carry powder described in the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As depicted in figs. 1 and 2, the utility model provides a kind of connecting tube that is used to carry powder, comprise: two ends, at least one end has double layer construction, wherein, one end of layer structure and an end of endothecium structure are connected to each other, and form the annular space of end opening one by one between described layer structure and described endothecium structure, and described layer structure and described endothecium structure are for to be made by flexible material.
The described connecting tube that is used for carrying powder, the other end of described layer structure is along the other end that axially extends, surpasses described endothecium structure laterally of connecting tube.
The described connecting tube that is used for carrying powder, described double layer construction are coaxial setting.
The described connecting tube that is used for carrying powder, described endothecium structure is reduced gradually by an end to its external diameter of the other end.
The described connecting tube that is used for carrying powder, described at least one end is a feed end.
The described connecting tube that is used for carrying powder, described connecting tube is for to be made by flexible material.
The described connecting tube that is used for carrying powder, described flexible material are rubber or plastics.
Connecting tube 1 of the present utility model includes two ends, wherein at least one end has double layer construction, endothecium structure 6 and layer structure 3 are made by flexible material, one end 7 of endothecium structure is connected to each other with an end 4 of layer structure, thereby between layer structure and endothecium structure, form annular space 12, an end opening of annular space.Above-mentioned have a double-deck end 2 and be the feed end of connecting tube, the discharge port 9 of powder-processed equipment is inserted in this annular space, and simultaneously, endothecium structure is inserted into discharge port inside, layer structure then is coated on the outside of discharge port, the slit between sealing endothecium structure and the discharge port.The inside of connecting tube is used to carry powder, and layer structure then plays the effect of sealing.
The external diameter of above-mentioned endothecium structure and the internal diameter of discharge port adapt.Preferably, the external diameter of endothecium structure is reduced gradually by an end to the other end, make endothecium structure be convenient to insert in the discharge port, simultaneously, endothecium structure can be slightly larger than the internal diameter of discharge port at the external diameter near the part of an end of its root, so that the outer wall of the inwall of discharge port and endothecium structure fits tightly.
The width of annular space is difficult for excessive, and when being easy to act as most in the discharge port insertion annular space, the inwall of layer structure and the outer wall of endothecium structure under the extruding of discharge port certain deformation take place.The other end of layer structure fits tightly the outer wall in discharge port.
The other end 5 of layer structure exceeds the other end 8 of endothecium structure, with the slit between better sealing discharge port and the endothecium structure.
Above-mentioned double layer construction not only makes an end of connecting tube can not come off with discharge port, and simultaneously, layer structure plays good aeroseal effect, has saved air seal pipe of the prior art, has simplified the structure of conveyance conduit.
When connecting tube only had an end 2 to take double-deck design, another end still can be connected with the material feeding mouth of hardwired mode with the powder jar.During hard the connection, the interface of the two is just relative, and fixes by flange.If powder is an air flammability powder, then between above-mentioned interface, seal by seal ring.
Another end 10 of connecting tube also can be the single layer structure of being made by flexible material, and the material feeding mouth 11 of powder jar is inserted into the inside of another end, and the inwall of another end and the outer wall of discharge port fit tightly.Double-deck design also can be adopted in another end of connecting tube.
All adopt above-mentionedly when being flexible coupling when two ends of connecting tube of the present utility model, just solved the problem of the easy accumulated powder of jointing in the prior art; Connecting tube of the present utility model also has characteristics easy to use, can realize quick connection.
The discharge port of the material feeding mouth of powder jar of the prior art and powder-processed equipment all has the flange that radially extends, and connecting tube of the present utility model can keep stable being connected with the two; When the discharge port of powder jar material feeding mouth and powder-processed equipment did not have flange, connecting tube then of the present utility model used convenient, connected better effects if.
When the whole employing of connecting tube flexible material was made, connecting tube had best deformability, was suitable for the big or vibration frequency condition with higher of Oscillation Amplitude of powder-processed equipment.
Flexible material of the present utility model is rubber or plastics.
Connecting tube of the present utility model is that vertical state uses when using.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the mode of execution, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
