Description

Fly ash concrete mixing device

Technical Field

The utility model belongs to the technical field of the concrete mixing and specifically relates to a fly ash concrete mixing device has been related to.

Background

The fly ash is a pozzolanic material and has no gelation property, when water exists at normal temperature, the fly ash can perform secondary reaction with concrete to generate hydrated calcium silicate gel which is insoluble in water, so that the possibility of dissolution is reduced, pores in the concrete are filled, and the strength and the impermeability of the concrete are improved. This effect of fly ash is known as the pozzolanic effect.

In reality, hardened fly ash particles or blocks exist in fly ash, and the quality of concrete is influenced when the fly ash is mixed with the concrete. Patent document No. 202020308508.9, application date 2020.03.13 discloses a large volume fly ash concrete dosing unit, and it stirs the powder through setting up the puddler in the storage hopper, but this mode is because the stirring leaf interval on the puddler is all great, is difficult to play effectual smashing to fly ash granule or piece. Patent document No. 201520990182.1, application date 2015.11.28 disclose a fly ash concrete configuration mixing processing apparatus, and it extrudees the breakage to the powder in the feeding process through the compression roller, and this mode is better to hardened granule or cubic comminuted effect, but smashes more thin, and the interval between the compression roller just is littleer, causes feed speed can be very slow, causes the inconvenience of use.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1-4, a fly ash concrete mixing device comprises a mixing mechanism 1 and a crushing mechanism, wherein the crushing mechanism comprises an extruding mechanism 2 and a crushing mechanism, a feed inlet 4 is formed at one end of the extruding mechanism 2, a discharge end of the extruding mechanism 2 is communicated with a feed end of the mixing mechanism 1, and the crushing mechanism is arranged at a discharge end of the extruding mechanism 2; the crushing mechanism comprises a frame type frame 3 and crushing pieces arranged in the frame type frame 3, wherein the crushing pieces are vertically and horizontally uniformly distributed in the frame type frame 3.

During the use, the powder by in feed inlet 4 gets into crowded material mechanism 2, crowded material mechanism 2 extrudees the powder to crushed aggregates mechanism, and most powder directly passes into agitating unit behind the crushed aggregates mechanism in, and granule or the cubic powder that few parts harden extrudees to crushed aggregates mechanism under the conveying force when crowded material mechanism 2 is carried the powder, gets into agitating unit 1 after the powder that crushed aggregates mechanism and extrusion force down granule or cubic powder are smashed to being less than crushed aggregates mechanism and cross the material aperture. In the preferred scheme, the direction towards the material extruding mechanism 2 discharge end on the crushed aggregates piece has seted up the cutting edge, and the cutting edge cooperation extrusion force plays the cutting effect to granule or cubic powder, promotes crushing efficiency. In practice, the crushed pieces comprise a transverse crushed piece 5 and a longitudinal crushed piece 6, a plurality of first knife grooves 7 are uniformly distributed at the bottom of the transverse crushed piece 5, a plurality of second knife grooves 8 are uniformly distributed at the top of the longitudinal crushed piece 6, the first knife grooves 7 of the transverse crushed piece 5 are clamped in the second knife grooves 8 of the longitudinal crushed piece 6, the plurality of transverse crushed pieces 5 and the plurality of longitudinal crushed pieces 6 form a knife net, and the mesh aperture of the knife net is the maximum diameter of the allowed particles.
