Description
Technical field
The utility model relates to building mechanical equipment field, particularly the anti-segregation of a kind of multiple spot blanking and homogenizing facility.
Technical background
As the primary raw material of premixing mortar, " dry sand " accounting reaches more than 70%, and the index " modulus of fineness " of its physical and chemical performance all has clear stipulaties in GB/T14684 " construction sand ".Before natural sand drying system, machine-processed finished sand warehouse-in, modulus of fineness measures as main control parameters, qualifiedly can put in storage.But in the blanking of our province dry-mixed mortar production line dry sand warehouse-in, outbound blanking process, the anti-segregation material blanking tube of general employing increase, the surrounding increase of tapering, bottom of the reservior help the mode of gas pad or both dual-purposes to alleviate laminated segregation phenomenon at present.Find during my houses market investigation, although equipment supplier is different, client generally reflect grating and modulus of fineness all qualified dry sand, after operation such as warehouse-in blanking, outbound discharging etc., its modulus of fineness changes again, have impact on quality and the combination property of mortar product, namely laminated segregation phenomenon thoroughly solves not yet.
The warehouse-in of dry sand physical property in production technology operation process, outbound link certainly lead to segregation phenomenon, and isolation-proof device is essential.
Warehouse-in technology for blanking is seen, the dry sand level before warehouse-in fits over qualified interval, but because the difference, particularly below 0.63mm microparticle decrease speed of gravity, air drag suffered by variable grain degree are extremely slow in warehouse-in process, result result in the laminated segregation of material.Can occur in storehouse that height layering is staggered through actual sampling test modulus of fineness.Illustrate: the modulus before warehouse-in is assumed to 2.5, then distribute to top, storehouse modulus of fineness from bottom of the reservior and present 2.8,2.1,2.7,2.3,3.0,2.2,2.9,2.0 ... so a kind of distribution, if discharging point misaligns, be again then another kind of layout, modulus of fineness presents the phenomenon that left and right sides deviation strengthens.
Outbound technology for blanking is seen, the major way of current nearly all mortar production line sand storage discharging is traditional intermediate discharging mode, namely first discharging in the middle of, subside dirty toward centre from highest point, because of the velocity contrast that the rolling of different size particles material on inclined-plane is fallen, bulky grain first blanking, then meal material are finally fine powder materials.Direct embodiment is in process of production exactly that discharging leading portion 2/3 modulus of fineness of expiring storehouse improves (supposing that benchmark is 2.5) to 2.8-3.5, and last 1/3 is 2.0-2.2, even lower.
Premixing mortar production line generally adopts at present increases anti-segregation material blanking tube, and the surrounding increase of tapering, bottom of the reservior helps the mode of gas pad or both dual-purposes, alleviates laminated segregation phenomenon.
Find after the solution analyzing domestic each equipment supplier: anti-segregation material blanking tube does not thoroughly solve the slow problem of below 0.63mm microparticle decrease speed, objectively also add the difficulty of manufacture, construction and installation, later maintenance.And the surrounding increase of tapering, bottom of the reservior helps gas pad mainly to use for reference the discharging thinking in the powder storehouses such as cement, much larger than cement of the proportion because of sand, cause anti-segregation effect not have the use occasion of cement powders storehouse obvious.
