Common premixing (do mix) mortar is formed after by mixing such as cement, sand, mineral admixture, flyash, building castoff, industrial tailings slag and mortar water-retaining admixtures.Because material, proportion, particle diameter and the fineness of these materials are all different, therefore premixing mortar is in links such as production, storage and transportation, very easily produce the physics segregation phenomenon of " thick, segmentation from " " gently, heavily drifting along ", thereby cause the unreasonable knot of premixing mortar to join, have a strong impact on the homogeneity of premixing mortar product, and then cause the instability of mortar quality.The principle of the generation of segregation phenomenon is as follows: all different mixed material of material, proportion, particle diameter and fineness is by the feed entrance (this feed entrance is positioned at the top of storing silo) of storing silo when entering the storing silo, be freely falling body " boundling shape " and fall, and progressively pile up formation " pyramid shape " bank to the bottom centre of storing silo.Aim at " pyramid " roof fall down in, thick material, then tumble the bottom all around to " pyramid ", the material thickness that makes is gradually separated, and forms at last and emanates.
When the premixing mortar with above-mentioned generation segregation phenomenon is applied to building wall, wall plastering and flooring, the floor leveling of architectural engineering, qualitative problems of construction such as will inevitably make the building mortar at these positions produce contraction, cracking, hollowing, to peel off; Architectural engineering accidents safe in utilization such as situation is serious, and building masonry wall, flooring percolating water also can take place, and the external thermal insulation system hollowing ftractures, the decoration of exterior wall face brick comes off, the safety that jeopardizes people's life and property.
Yet production, logistics and storage facilities that domestic premixing mortar production industry uses fail fundamentally to solve the segregation problem of premixing dry-mixed mortar so far, thereby have left over the hidden danger of mortar quality and construction quality.
Summary of the invention
The technical problems to be solved in the utility model provides the anti-mortar segregation of a kind of taper shape and leaks sieve, it can prevent the segregation phenomenon that premixing mortar is produced in production, transportation, storage process, thereby guarantees the homogeneity and the high-quality match ratio of premixing (do and mix) mortar.
In order to solve the problems of the technologies described above, the utility model provides the anti-mortar segregation of a kind of taper shape to leak sieve, comprises umbrella cover shape housing, and the mesh assemblies of at least 3 circles are set on the surface of umbrella cover shape housing, and every circle mesh assembly and mesh that evenly arrange identical by the aperture formed.
Leak the improvement of sieving as the anti-mortar segregation of taper shape of the present utility model: the mesh assemblies of above-mentioned at least 3 circles all are parallel to the bottom of umbrella cover shape housing; And to the bottom of umbrella cover shape housing, the aperture of mesh increases successively along the top of umbrella cover shape housing.
Leak the further improvement of sieving as the anti-mortar segregation of taper shape of the present utility model: mesh is circle, ellipse, triangle, quadrangle or polygon.
Leak the further improvement of sieving as the anti-mortar segregation of taper shape of the present utility model: quadrangle is square, rhombus or rectangle.
When the anti-mortar segregation of taper shape of the present utility model leaks the sieve actual fabrication, can adopt the mode of surperficial punching press, cutting or casting one-body molded.Consider that to material wear ability and durability requirement the selected material of umbrella cover shape housing should possess favorable rigidity and toughness, so umbrella cover shape housing can select for use materials such as the pig iron, steel plate or toughened plastic to make.The anti-mortar segregation of taper shape of the present utility model leaks when sieve is actual to be used, be fixedly installed in the inner chamber of storing silo, and be positioned at storing silo charging aperture under.When the mixed material that is " boundling shape " freely falling body from charging aperture touches umbrella cover shape housing surperficial, disperseed all around and be " drizzle shape " evenly to fall from mesh, heap rises to make mixed material begin to be the level of state progressively from the bottom of storing silo, avoided the appearance of " pyramid shape " moulding fully, stop the separation of various thick, middle materials in the mixed material, that is prevented the generation of segregation phenomenon.
It is simple, with low cost that the anti-mortar segregation of taper shape of the present utility model leaks sieve structure, and the structure that need not to change original storing silo just can be installed and used; And can effectively prevent the generation of segregation phenomenon; Therefore be applicable to large-scale production and use; Market application foreground is wide, and economic benefit and social benefit are two good.
