The specific embodiment

As shown in Figure 1 and Figure 2, the utility model includes material sucking port 1, the mass transport pipeline that is connected with material sucking port, is connected in the feeder 3 of the mass transport pipeline other end, the dust pelletizing system with dust exhaustor 7 being communicated with feeder.On dust exhaustor 7, by pipeline, be connected with dedusting fan 6, on the pipeline that connects dust exhaustor 7 and dedusting fan 6, be provided with dedusting butterfly valve 10.Two material pipelines that described mass transport pipeline is comprised of in the materail tube 2,2 ' of material sucking port two parallel joins, described feeder is the extra quality mouthful of feeder with two inlet point 3a, 3b, two materail tubes 2,2 ' connect respectively two inlet point 3a, 3b of feeder, on two materail tubes 2,2 ', be respectively arranged with gate valve 8,8 ', feeder bottom is with blanking port 3f.Feeder of the present invention inside can be pure storehouse feeder as shown in Figure 3, also can be two storehouses feeder that two feed bin 3c, 3d are set as shown in Figure 4, Figure 5, a corresponding inlet point of feed bin.When adopting two storehouses feeder, the blanking port of feeder can be as Fig. 4, Figure 7 shows that a shared blanking port 3f who is simultaneously communicated with two feed bin 3c, 3d, also can be as shown in Figure 5, Figure 6 for being communicated with respectively separately two blanking port 3f1, the 3f2 of a feed bin.When if system fed distance is long or voltage loss is large, can configure in addition as shown in Figure 1 two Fans 5,5 ', two feed bins of feeder connect blower fan 5,5 ' separately by pipeline respectively, the air outlet of two Fans is all connected with the dust exhaustor 7 of dust pelletizing system by dust discharge pipeline 4, on the pipeline that connects feed bin and blower fan, sets out respectively air port butterfly valve 9,9 '.Now from material sucking port 1, to the required crushing of feeder section, by blower fan 5,5 ', provided, after dedusting section crushing by dedusting fan 6, provided.If system fed distance is not long or voltage loss is little, only need dedusting fan 6 is set as shown in Figure 2 after dust exhaustor, the crushing of whole system is provided by dedusting fan 6.The air quantity of dedusting fan 6 is two Fans 5,5 ' air quantity sum.Material sucking port 1 can be respectively given one of them the independent feed in two materail tubes 2,2 ', also can be simultaneously to two-way materail tube feed.Every materail tube all can meet respectively the conveying of half left and right of maximum technique flow, starts the strength conveying that can meet maximum technique flow simultaneously.Two feed bin 3c, 3d of two storehouses feeder 3 are separate configurations blower fan 5,5 ' separately respectively, and the corresponding road material pipeline of every Fans is responsible for the strength of material in corresponding material pipeline and is carried.Feeder can meet two materail tubes feed and Conveyance and dedusting requirement during feed simultaneously respectively.Dust pelletizing system adopts single dust removing tube 4 and single dedusting fan 6 forms, and dedusting fan 6 is responsible for conveying and the discharge of dust pelletizing system air-flow.Dedusting fan adopts frequency changing regulating speed control apparatus, by changing the rotating speed of blower fan, thereby changes fan delivery to adapt to compared with the technological requirement of low discharge mass transport, and simultaneity factor is more energy-conservation.And two materail tubes are when all start, because systematic air flow doubles, the wind speed of dust removal left and right that also can double.During practical operation, can, by regulating dedusting butterfly valve 10, suitably reduce dust pelletizing system total blast volume to reduce wind speed of dust removal.

Working process of the present utility model is as follows: when carrying the tobacco of larger flow, material sucking port 1 is simultaneously to materail tube 2 and 2 ' feed, and blower fan 5 and 5 ' all starts, and while two materail tube gate valves 8,8 ' and two air outlet butterfly valve 9,9 ' are all opened completely.Material is discharged from feeder 3 through the conveying of materail tube, dirt gas is respectively from the left and right dedusting mouth on feeder top, after blower fan 5 and 5 ', gather, enter dust exhaustor 7 carry out dedusting by dust removing tube 4, the pure qi (oxygen) after dedusting enters atmosphere through dedusting fan 6, silencer 11 etc.When carry compared with low discharge (flow only have half of maximum technique flow even less) tobacco time, 1 of material sucking port is to single materail tube 2 feed for example, blower fan 5 starts, materail tube gate valve 8, air outlet butterfly valve 9 are opened completely simultaneously, and another group materail tube gate valve 8 ', air outlet butterfly valve 9 ' are closed completely.Material is discharged from feeder 3 through the conveying of materail tube 2, and dirt gas, from the right dedusting mouth on feeder top, after blower fan 5, enters dust exhaustor 7 by dust removing tube 4 and carries out dedusting, and the pure qi (oxygen) after dedusting enters atmosphere through blower fan 6, silencer 11 etc.In system work process, blower fan 5,5 ' overcomes the omnidistance crushing of whole system in the mode of series connection relay with dedusting fan 6; And match at air quantity, the total blast volume of blower fan 6 should be the air quantity sum of blower fan 5 and 5 ', can meet the air quantity requirement of larger flow mass transport, blower fan 6 adopts frequency changing regulating speed control apparatus simultaneously, by changing the rotating speed of blower fan, thereby change fan delivery to adapt to compared with the technological requirement of low discharge mass transport.Because dust pelletizing system is being carried larger flow material and during compared with low discharge material, the air quantity different (while carrying larger flow material, systematic air flow is 2 times while carrying compared with low discharge material) of its system, therefore under two kinds of mode of operations, the air velocity duct of dust pelletizing system is different.For example, if the about 12m/s of the wind speed of dust removal left and right design when starting single materail tube of dust removing tube caliber guarantees in cleaning shaft not dust stratification, when so two materail tubes all start, because systematic air flow doubles, wind speed of dust removal is about 24m/s left and right.
