Description
Technical field
The utility model relates to a kind of preparation facilities of metallic silicon power.
Background technology
Silica flour processing refers to the silico briquette (25 ~ 80mm) that will smelt out, broken through special technique, produces the process becoming the silica flour of designated size (usual 80 ~ 400 μm) scope.For the metallic silicon power of organosilicon and production of polysilicon, corresponding technical indicator must be possessed, the key technical index of metallic silicon power: chemical analysis, granularity, pattern, specific area, physicochemical property embody the chemical reactivity of metallic silicon power, key technical index produces an important evidence of organosilicon, polysilicon high-quality.
The size indicator of silica flour directly has influence on its pattern and specific area, thus directly have influence on the chemical reactivity of metallic silicon power, therefore polysilicon and the granularity of organosilicon to metallic silicon power used have strict requirement, under the prerequisite meeting instructions for use, how reducing powder process cost is the key improving production benefit.
The device taking silico briquette as waste silica flour is a lot.Existing silica flour process units mainly contains horizontal and vertical punching and revolves two kinds of devices.
Described horizontal punching revolves block diagram as shown in Figure 1, and silico briquette, through jaw crusher primary comminution, enters particle storehouse, send into horizontal pulverizer again to grind, the material of pulverizing is taken out of by air-introduced machine air-flow, is separated through cyclone separator, fine powder is collected through cloth bag dust catcher and is entered fine powder bin, and packaging is outer sells; Mixed meal enters linear vibrating screen screening, and on sieve, coarse grain returns horizontal pulverizer, and undersize (middle powder) enters finished bin.
Described vertical punching revolves block diagram as shown in Figure 2, and silico briquette, through jaw crusher primary comminution, enters particle storehouse, then sends into vertical crusher and grind, and the material of pulverizing enters bucket elevator and is separated, and fine powder is collected through cloth bag dust catcher and entered fine powder bin, and packaging is outer sells; Mixed meal enters linear vibrating screen screening, and on sieve, coarse grain returns horizontal pulverizer, and undersize (middle powder) enters finished bin.
Described jaw crusher as shown in Figure 7, its working portion is two pieces of jaws, one is that fixed jaw 111(determines jaw), vertically (or upper end slightly flare) is fixed on body antetheca, another is that sewing jaw 112(moves jaw), inclined position, forms up big and down small crusher chamber (working chamber) with fixed jaw.Sewing jaw does periodic reciprocating motion facing to fixed jaw, time and separate, time and close.Time separately, material enters crusher chamber, and finished product draws off from bottom; Near time, the material be contained between two pieces of jaws is squeezed, bending and slabbing action and broken.Jaw crusher discharging granular size is adjusted by adjustment discharge gate size.Less than 3 centimetres can be reached to the fragmentation of metal silico briquette, but have the situation that coarse granule drops.
Described linear vibrating screen utilizes vibrating motor exciting as vibration source, make material tossed on screen cloth, do rectilinear motion forward simultaneously, material enters the charging aperture of screening machine equably from batcher, the oversize of several specifications is produced by multilayer screen cloth, screenings, discharges from respective outlet respectively.The particle pulverizing out due to described mechanical mill is combination grain, thickness powder all mixes, when sieving with linear vibrating screen, fine powder easily sticks on coarse granule, not easily sieve, the time of staying of material on screen cloth is long, and comparatively large to the wearing and tearing of screen cloth, screening efficiency is relatively low, and more superfine powder sticks on conforming particle, can impact product quality.
In sum, in silica flour preparation technology, jaw crusher and linear vibrating screen is adopted to reduce production capacity and the one-pass finished rate of silica flour.
