Technical field:
The utility model relates to submicron order powder gas phase classifying equipoment technical field, is specifically related to streaming cyclone separator in one.
Background technology:
In known submicron order powder gas phase body classifying equipoment, conventional is centrifugal cyclone separator, generally comprise cyclone body, the aggregate bin of cyclone body below, the feed pipe of cyclone body sidewall top, the top stream pipe of cyclone body top, top stream pipe and induced draught system (as air blast etc.) be connected in time air-flow is drawn.The centrifugal cyclone separator of this routine only has an ascending air exhaust core pipe to push up stream pipe in cyclone body.
Powder enters after cyclone body under the effect of air-flow, forms the outside circulation moving downward in cyclone body outside under because of the effect of gravity and centrifugal force, and in air-flow, bulky grain powder moves downward and enters aggregate bin along whirlwind body wall; In cyclone body, be formed centrally the interior circulation moving upward, in air-flow, tiny powder moves upward at cyclone body center.Interior circulation is reverse and go at uphill process China and foreign countries sidewind and the outside circulation air-flow moving downward, because the air-flow that contains submicron order powder is entered after cyclone body by feed pipe, must be through between exhaust core pipe outer wall and cyclone body cylinder inboard wall, therefore unavoidably can make quite a few air-flow not pass through the separated space of cyclone body and directly discharge (short circuit flow rate) from exhaust core pipe bottom, make cyclone body inlet air flow discharge air-flow with top stream pipe and cause short circuit phenomenon, just because the cyclone inlet air-flow of this routine is discharged air flow shortcircuit phenomenon with top stream pipe, there is part bulky grain powder to enter in the lump top stream pipe because of short circuit and superfine powder in cyclone body import department, enter in fines collection equipment, fine powder body with compared with coarse granule powder form cross pollution.
In addition, conventional powder gas phase classifying equipoment cyclone separator is discharged air-flow because of inlet air flow with top stream pipe and is had air flow shortcircuit phenomenon, contains bulky grain powder and causes classification efficiency low, weak effect in superfine powder.At MLCC(chip multilayer ceramic capacitor) in industry, require powder granularity to be evenly distributed, effectiveness of classification is high.Take 03 specification nickel powder as example, nickel powder used requires, not containing 0.8 micro particles, to adopt conventional centrifugal cyclone separator, need can obtain by repeatedly repeating classification the product of even particle size distribution, time-consuming, inefficiency.
Utility model content:
The utility model, for the above-mentioned deficiency of prior art, provides a kind of classification efficiency high, effective, is difficult for producing the middle streaming cyclone separator of cross pollution.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: streaming cyclone separator in one, comprise cyclone body, the aggregate bin of cyclone body below, the feed pipe of cyclone body sidewall top, the top stream pipe of cyclone body upper end, is characterized in that: described cyclone body upper end is also provided with middle stream pipe, described middle stream pipe box is located at stream pipe outside, top and is communicated with cyclone body.
Adopt said structure, due to the setting of middle stream pipe, powder enters after cyclone body under the effect of air-flow, and powder rotates under the effect of air-flow in cyclone body, the inside and outside sidewind of cyclone body forms the outside circulation moving downward, the aggregate bin below entering along cyclone body inwall under Action of Gravity Field; Form the interior circulation moving upward at cyclone body central part air-flow, interior circulation is in the time moving up in middle stream pipe, and interior circulation outside, containing entering middle stream pipe compared with the air-flow of coarse dispersion grain, is discharged and collected by middle flow export pipe; Inside interior circulation, enter top stream pipe discharge containing the air-flow of superfine powder and collect, thereby avoid in the time entering cyclone body, causing cross pollution because short circuit directly enters top stream pipe compared with coarse dispersion particle; Said structure has been realized the classification of micron-sized powder different-grain diameter powder, has avoided cross pollution, and separative efficiency is high, effective.
As preferably, described middle stream Guan Yuding stream pipe is for being coaxially set.Adopt this structure, in powder separation process, can make interior circulation outside containing entering uniformly middle stream pipe compared with the air-flow of coarse dispersion, interior circulation inner side is containing evenly enter top stream pipe compared with the air-flow of fine powder body (superfine powder).Thereby realize the classification of different-grain diameter powder, avoid cross pollution.
As preferably, described middle stream Guan Yuding stream bore, than being 2-3:1, adopts said structure, can make in interior circulation compared with coarse dispersion with separate than more completely compared with fine powder body, avoid cross pollution, classification is more thorough.
As preferably, described feed pipe is tangential direction with the staving of cyclone body and is connected.Adopt said structure, the air-flow that contains powder can have larger revolving force after entering cyclone body, and the time of separating spiral-flow is more of a specified duration, separates more thorough.
As preferably, the import of described cyclone body feed pipe is square type, adopts this structure, and powder enters more smooth, and treating capacity is larger, and separative efficiency is high.
Accompanying drawing explanation:
The structural representation of streaming cyclone separator in Fig. 1 the utility model.
The top view structural representation of streaming cyclone separator in Fig. 2 the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing and instantiation, the present invention is further described.
As shown in Figure 1: middle streaming cyclone separator of the present utility model, comprise cyclone body 2, the aggregate bin 3 of cyclone body 2 belows, the feed pipe 1 of cyclone body 2 sidewall tops, the top stream pipe 5 of cyclone body 2 upper ends, the utility model is different from being characterised in that of above-mentioned prior art: described cyclone body 2 upper ends are also provided with middle stream pipe 4, and described middle stream pipe 4 is sheathed on stream pipe 5 outsides, top and is communicated with cyclone body 2.Above-mentioned top stream pipe 5 and middle stream pipe 4 all will be communicated with induced draught system as air blast etc., to facilitate powder air-flow to discharge in time.
Top of the present utility model stream pipe is placed in stream pipe inside, is fixed by welding in middle stream pipe top, and middle stream pipe is connected with cyclone body upper end top cover by welding; Cyclone body upper end top cover connects with cyclone body by flange, and middle stream pipe outlet connects with induced draught system, and top stream pipe outlet connects with induced draught system.Powder tangentially enters cyclone separator (see figure 2) in import department's journey of feed pipe 1 after disperseing by the dry gas from compressor.Powder is under the effect of air-flow, in cyclone separator, produce and rotatablely move, form circulation, under the effect of gravity and centrifugal force, the outer sidewind of cyclone body forms the outside circulation moving downward, and in air-flow, big particle powder is along being moved into aggregate bin under cyclone separator lateral; The outer sidewind of cyclone body forms the interior circulation moving upward, and in interior circulation air-flow, draws compared with flowing pipe in coarse granule powder warp, and relatively fine particle powder is drawn through top stream pipe.
