Description

A kind of device of the heterogeneous continuous stirring of gravity type of light-weight aggregate thermal insulation goods
Technical field
The invention belongs to mixed stirring device field, particularly relate to a kind of device of the heterogeneous continuous stirring of gravity type of light-weight aggregate thermal insulation goods.
Background technology
Being uniformly mixed is conventional process means prepared by construction material mixing of materials, applies very general.Particularly after inorganic light-weight aggregate thermal insulation dry powder and mortar and inorganic light-weight aggregate thermal insulation plate emerge, it all includes in producing and adopts stirring means to make the mixed uniformly technique of various materials, and the uniformity of material stirring and stability are had to very high requirement.At present, conventional agitating mode can be classified as 2 kinds: a kind of is exactly once to stir, and all raw materials mix stirring, once complete, time saving and energy saving but mixing effect is not good; Another kind is Multi-stage stirring, and each stirring is just added a kind of material until last all materials have added, although it is loaded down with trivial details finally to stir the high process of homogeneity.And the whipping process of inorganic light-weight aggregate goods usually relates to being uniformly mixed between the liquid of powder, solid, different viscosities, rely on the equipment that is commonly used to stir solid article can have considerable problem.
First, according to existing stirring technique and equipment, no matter disposable stirring or Multi-stage stirring, because the unit weight of light-weight aggregate and other raw materials differs greatly, so occur a little that in storage, stirring and discharging process sluggishness just has lamination and produces, mixed material stability is difficult to guarantee; Secondly, if there is liquid, solid and powder in whipping process simultaneously, reuniting easily appears in powder, dispersed variation, makes to stir rear material volume weight difference in distribution large, and the normal thickener that uses in raw material, can improve material viscosity, more make the powder self once stirring to mix; Again, because 30~60 times of the powder volume differences that in inorganic light-weight aggregate thermal insulation board raw material, bulky aggregate and volume are little, and light-weight aggregate aggregate mostly is the bulky grain with pore structure, it is inner that powder easily enters light-weight aggregate aggregate, cannot reach in the outside effect effectively adhering to of lightweight aggregate; Finally, light-weight aggregate thermal insulation aggregate is the frangible solid particle of a kind of lightweight, poor stability, the too high or long fragmentation that all can cause light-weight aggregate of mixing time of stirring intensity.
Except the problem that the characteristic of light-weight aggregate itself is brought, existing stirring technique continuity can not brought problem for stirring result by force yet.Because no matter be once to stir and Multi-stage stirring, it is all charging-stirring-discharging-circulation of charging again, once stir and only have one batch, batch with batch between material uniformity and stability all there will be unavoidably fluctuation and difference, finally can cause the performance of goods to occur fluctuating.
Prior art proposes to open charge door on storage tank tank body top, and inside adds oral siphon, and mixing plant is installed at conical discharge port place, bottom.This device, for the stirring of light-weight aggregate goods, has many problems.The first, its agitating mode is just not suitable for light-weight aggregate goods, because light-weight aggregate itself is frangible, so can only use gravity type to stir, the forced action type stirring meeting of this patent all blends light-weight aggregate, obviously undesirable; The second, light-weight aggregate and other material densities differ greatly, and at this storage tank, there will be obvious lamination; The 3rd, it can not add while stirring other raw materials in stirring; The 4th, whole whipping process is the equal of once to stir, for the light-weight aggregate goods stirring technique that has liquid, powder, solid material simultaneously, and lack of uniformity, mixing quality fluctuation is too large; The 5th, amount of agitation is little, for the rear step operation of light-weight aggregate goods, has very large restriction.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of device of the heterogeneous continuous stirring of gravity type of light-weight aggregate thermal insulation goods, to solve the various materials of light-weight aggregate thermal insulation goods, stir inhomogeneous, the unsettled technical problem of mixing quality, make the raw material stirring of number of different types light-weight aggregate goods orderly, unified, in an agitator, complete consistently, both the dispersion, the mixing that had guaranteed material are highly even, do not destroy light-weight aggregate, guaranteed the continous-stable of mixing quality simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: the device that a kind of heterogeneous continuous stirring of gravity type of light-weight aggregate thermal insulation goods is provided, comprise mixing drum and feed bin, one side of described mixing drum is furnished with feed bin, the discharging opening of feed bin is towards the opening part of mixing drum, on the shaft core position of described mixing drum, liquid line is housed, it is inner that the jet of liquid line is aimed at mixing drum, on the cylindrical of described mixing drum, be evenly equipped with some buckets, the arranged beneath of mixing drum has hopper, some buckets are corresponding with the position of hopper, one end of described hopper connects the powder material warehouse that is positioned at mixing drum side, described mixing drum inside is evenly equipped with some deflectors, travelling gear is equipped with in mixing drum bottom.
Described mixing drum and ground are 3~5 degree slant settings, make compound one end from mixing drum under the guiding of deflector be transported to the other end.
Meter is equipped with in the bottom of the import of described liquid line, feed bin and powder material warehouse, in order to control material addition.
Described meter connects computer by sensor.
Beneficial effect
Owing to adopting technique scheme, the present invention compared with prior art, has following advantage and good effect:
This device can make the raw material of number of different types light-weight aggregate goods stir in order, unified, in an agitator, complete consistently, both guaranteed that the dispersion of material, mixing energy height are even, do not destroy light-weight aggregate, can guarantee again the continous-stable of mixing quality; Can save energy consumption, reduce maintenance capacity, operational ton, alleviate government pressure.
