Accompanying drawing explanation
By referring to the description of accompanying drawing to the utility model embodiment, above-mentioned and other objects of the present utility model, feature and advantage will be more clear, in the accompanying drawings:
Fig. 1 is that the utility model jumbo bag sack is dust-proof and collect the part sectional view of fall-out materials device.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, various embodiment of the present utility model is described in more detail.In various figures, identical element adopts same or similar Reference numeral to represent.For the sake of clarity, the various piece in accompanying drawing is not drawn in proportion.
As shown in Figure 1, the jumbo bag sack that provides of the utility model is dust-proof and collect fall-out materials device and comprise lower stream pipe 1, taper flow pipe 2, meet upstream device stream pipe 3 and support and connection portion 4.Described lower stream pipe 1 is positioned at described taper flow pipe 2, and described support and connection portion 4 is evenly distributed between described lower stream pipe 1 and taper flow pipe 2, and described lower stream pipe 1 is fixedly connected with the inwall of described taper flow pipe 2 by described support and connection portion 4; The lower end of described taper flow pipe 2 is fixedly connected with the described upper end connecing upstream device stream pipe 3.
Described lower stream pipe 1 comprises sack connecting portion 11 and mozzle 12, described sack connecting portion 11 is a taper pipe, and its upper end diameter is comparatively large, and the edge of upper end is formed as circular arc, reduce the wearing and tearing to jumbo bag sack, described sack connecting portion 11 is for being connected with jumbo bag sack and fixing.The internal diameter of described sack connecting portion 11 lower end is equal with the internal diameter of described mozzle 12, and is fixedly connected with the upper end of described mozzle 12.
Described taper flow pipe 2 is the conical tube that upper end diameter is large, lower end diameter is little, and its upper-end inner diameter is greater than the external diameter of sack connecting portion 11 upper end on described lower stream pipe 1, and bottom diameter equals or slightly larger than the external diameter of the mozzle 12 on described lower stream pipe 1.Preferably, can also arrange extension 21 (for being provided with the situation of extension 21 in figure) in the upper end of described taper flow pipe 2, namely described taper flow pipe 2 comprises extension 21 and tapered portion 22, to prevent dust recycling better.Described tapered portion 22 is the conical tube that upper end diameter is large, lower end diameter is little, and described extension 21 is cylindrical shape, and its internal diameter is identical with described tapered portion 22 upper-end inner diameter, and its lower end is fixedly connected with described tapered portion 22 upper end.
The described upstream device stream pipe 3 that connects is the cylindrical shape that internal diameter is equal with described taper flow pipe 2 bottom diameter, described in connect the upper end of upstream device stream pipe 3 and the lower end of described taper flow pipe 2 and be fixedly connected with.
Described lower stream pipe 1 is positioned at inside described taper flow pipe 2, and is fixedly connected with described taper flow pipe 2 by support and connection portion 4 described in hoop well-distributed, makes to form torus section 5 between described lower stream pipe 1 and described taper flow pipe 2.Described sack connecting portion 11 upper end is higher than extension 21 upper end on described taper flow pipe 2, to be connected with jumbo bag sack, and make the sack edge connected with described sack connecting portion 11 be positioned at below place, described extension 21 upper end plane, the material that is scattered to make sack can not drop to outside described taper flow pipe 2, and better can prevent dust recycling.Described support and connection portion 4 is tabular or shaft-like.Described lower stream pipe 1 lower end and described taper flow pipe 2 lower end are vertically arranged with certain gap 6 according to material characteristic.Preferably, described gap 6 is 30-80mm.The described upper end connecing upstream device stream pipe 3 is fixedly connected with the lower end of described taper flow pipe 2, described gap 6 makes described torus section 5 meet upstream device Liu Guan 3 UNICOM with described, to make air and the material that is scattered can connect upstream device stream pipe 3 described in described torus section 5 enters.
The utility model jumbo bag sack using method that is dust-proof and collection fall-out materials device is: be enclosed within by jumbo bag sack on the sack connecting portion 11 of described lower stream pipe 1, and be fixed.Separate mouth opening and start blanking, in blanking process, the air draught of downstream dust eliminating plant makes to form certain negative pressure in described torus section 5, torus section 5, gap 6 and connect in upstream device stream pipe 3 formed air-flow, the dust that sack can be made to fly away enters described torus section 5 with air-flow, and entered by gap 6 and connect in upstream device stream pipe 3, avoid dust from flying to pollute.And, because air enters by described torus section 5, make can not cause excessive negative pressure in jumbo bag, be conducive to smooth blanking.The sack material that is scattered enters described torus section 5, and connects in upstream device stream pipe 3 described in being entered by described gap 6, decreases cleaning and to be scattered the link of material, it also avoid because the cleaning secondary dust that material causes that is scattered pollutes simultaneously.Meanwhile, the air-flow entered by described torus section 5 be also conducive to the material that is scattered fallen into wherein entered by described gap 6 described in connect upstream device stream pipe 3, and enter upstream device.
It should be noted that in this article, such as the upper and lower position relationship that waits is because the convenience described and a kind of relative position relationship between these parts of limiting, instead of the restriction of a kind of absolute positional relation to these parts.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
