Description
Technical field
The utility model relates to a kind of high-performance cement expansive agent finish fineness pick-up unit.
Background technology
Cement expansive material is a kind of by hydration reaction, generates a kind of, constitutionally stable, compound with certain volume harmless to concrete, shrink, reduce the generation of distress in concrete with compensating concrete at inside concrete.
Current, cement expansive material market development is rapid, and high-performance cement expansive agent is used for impermeable structure, design that overlength is seamless and construction, mass concrete and splits the control etc. of oozing and all obtain very good effect, and its application prospect is boundless.Current swelling agent fineness control aspect major part only pays close attention to 80 μm and 1.18mm, due to swelling agent grain diameter and swelling agent performance closely related, along with the development of high-performance cement expansive agent, so people more and more pay attention to more effectively monitoring high-performance cement expansive agent particle size distribution.
When surveying swelling agent fineness with swelling agent screen analyzer, swelling agent fine powder can constantly be adsorbed in negative pressure screen cover, if do not beat down the accuracy that can affect detected value, classic method beats screen cover gently with wooden mallet or iron staff, the fine powder be adsorbed in screen cover is made to drop in sieve, due to wooden mallet or iron staff, to beat area uneven, and heavier-weight, beat the problems such as screen cover there will be screen cover distortion, gas leakage is even broken for a long time.
Summary of the invention
The purpose of this utility model aims to provide easy to operate, environmental protection and energy saving, can produce in enormous quantities continuously, a kind of high-performance cement expansive agent finish fineness pick-up unit that the properties of product of production are superior.
Implementation of the present utility model is, a kind of high-performance cement expansive agent finish fineness pick-up unit, fluted on negative pressure screen analyzer, the shrinkage pool placing 45 μm, 80 μm, 150 μm and 300 μm negative pressure sieves is respectively had in groove, each negative pressure sieve there is cover plate, there is O-ring seal between negative pressure sieve and cover plate, be furnished with the negative pressure sieve beaing negative pressure screen cover plate and beat rod.
When using the utility model, the high-performance cement expansive agent taken according to quantity needed for 45 μm, 80 μm, 150 μm, 300 μm negative pressure sieves is placed in each negative pressure sieve, pressure seal ring, lid cover plate, negative pressure sieve is placed in negative pressure screen analyzer groove, under the pressure of 40 ~ 60pa, keep 120s, weigh and respectively tail over value, with this synthetic determination high-performance cement expansive agent finish fineness, in testing process, constantly beat rod with negative pressure sieve rap negative pressure screen cover plate.
The utility model structure is simple, easy to operate, can monitor the grain diameter grating of high-performance cement expansive agent finished product accurately and effectively, and in minimizing swelling agent finished product, bulky grain is to the harm of concrete stability.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view,
Fig. 2 is the shrinkage pool structural representation in groove,
Fig. 3 is that negative pressure sieve beats bar structure schematic diagram.
Embodiment
With reference to the accompanying drawings in detail the utility model is described in detail.
With reference to Fig. 1,2, on negative pressure screen analyzer 1 fluted 2, in groove, there is the shrinkage pool one, two, three, 47,8,9,10 placing 45 μm of negative pressure screen analyzer negative pressure sieves, 80 μm of negative pressure screen analyzer negative pressure sieves, 150 μm of negative pressure screen analyzer negative pressure sieves and 300 μm of negative pressure screen analyzer negative pressure sieves respectively.Each negative pressure sieve there is cover plate, between negative pressure sieve and cover plate, has O-ring seal, be furnished with the negative pressure sieve beaing negative pressure screen cover plate and beat rod.Described negative pressure sieve screen cloth material is 304 stainless steel wires.Described negative pressure sieve sieve aperture is square opening.
With reference to Fig. 3, the plastic strip that described negative pressure sieve beats rod inserts in wood handle 4, and seals interface 3 with bonded adhesives, plastic strip overcoat rubber sleeve.Plastic strip is V-type plastic strip 6, V-type plastic strip both sides cover rubber sleeve 5.Due to V-type plastic strip both sides cover rubber sleeve, when beaing negative pressure sieve screen cover, rubber sleeve contact negative pressure sieve screen cover, it is not rigid beaing, therefore energy available protecting negative pressure sieve screen cover, unlikely its damages or distortion.
When using the utility model, by particle size distribution requirement, the high-performance cement expansive agent taken according to quantity needed for 45 μm, 80 μm, 150 μm, 300 μm negative pressure sieves is placed in respective negative pressure sieve respectively, press O-ring seal, after covering cover plate, the groove 2 being placed in negative pressure screen analyzer 1 respectively obtains each shrinkage pool, under the pressure of 40 ~ 60pa, keep 120s, what weigh each negative pressure sieve tails over value, tails over result synthetic determination high-performance cement expansive agent finish fineness from negative pressure.For making to sieve fully, in testing process, constantly beaing rod with negative pressure sieve rap negative pressure screen cover plate.
The utility model structure is simple, easy to operate, can monitor the grain diameter grating of high-performance cement expansive agent finished product accurately and effectively, and in minimizing swelling agent finished product, bulky grain is to the harm of concrete stability.
