Description

A kind of novel not sticky lime-ash hopper

Technical field

The utility model relates to the transformation of pnenmatic slag handling system hopper, particularly relates to a kind of novel not sticky lime-ash hopper.

Background technology

Our factory 2 × 300MW unit engineering bottom slag adopts wet type pnenmatic slag handling system, and namely every platform stove establishes 2 scraper plate slag conveyers, 2 chain buckets.End slag delivers to bucket elevator by mechanical conveying system be cooled to uniform temperature in dragveyer after, by bucket elevator bunker lift to slag storehouse.Every platform bucket elevator is equipped with 76 hoppers, and hopper is fixed by chain, and between every two hoppers, spacing is 7 centimeters, is driven promote hopper by reductor.

Hopper major metal structure is carbon steel, and wherein the massfraction of carbon is less than 2.11%, and not containing other alloying elements specially added.Because its hardness is comparatively large, but plasticity is lower, so metal astringency is larger.When lime-ash transfers to hopper by mechanical conveying system, because containing larger moisture, therefore cause hopper interior surface adhesion lime-ash, hopper periodical duty, cause lime-ash adhesion amount larger, within the unit time, the viscous force of hopper adhesive band water lime-ash can calculate with μ=μ 0 × e^ [-λ (t-t0)], is 0.839 × 10^(-3) (Pas).Because hopper adhesion lime-ash, cause hopper to be exerted oneself and can not reach absolutely.Frequent appearance, because hopper deposits lime-ash in a large number, causes bucket elevator to be suppressed and stops fault.The present invention is not extensively promoted so far.

Utility model content

It is low that technical problem to be solved in the utility model is to provide one to have cost of manufacture, efficiency height and short novel sticky lime-ash hopper consuming time.

For solving the problem, the utility model adopts following technical scheme:

A kind of novel not sticky lime-ash hopper, comprise hopper outside face and hopper inside face, described hopper outside face is provided with positioning bolt hole, described positioning bolt hole is provided with more than one, and arrange in two rows on hopper outside face, described hopper inside face is positioned at the below of hopper outside face, described hopper inside face comprises chain and arranges rectangle and chain, described chain arranges that rectangle is positioned at the middle part on hopper surface, described chain is arranged on chain and arranges in rectangle, described chain is provided with one or more, two ends and the chain of described chain arrange that the two ends of rectangle are sewed up mutually.

As preferably, described positioning bolt hole is provided with four, can fix with hopper at bucket elevator chain.

As preferably, described chain is provided with 11, and is uniformly distributed, and after hopper uses chainlet to be uniformly distributed, enhances the surperficial elastic force of hopper, decreases metal viscous force.

As preferably, cm apart between described every bar chain, is conducive to preventing mutual frictional impact between chain from causing wearing and tearing.

As preferably, described every bar chain has four links to interlink, with chain, the two ends being conducive to chain arrange that rectangle is alleviated fixing mutually.

The beneficial effects of the utility model are: use the improved hopper of the technology.Confirmed by on-the-spot real work, make hopper Surface adhesion force table little, lime-ash enters water amount after hopper to be reduced, and bucket elevator is exerted oneself increase, extends the period of inspection and repair of bucket elevator, reduce maintenance cost.

Accompanying drawing explanation

Fig. 1 is the integral structure figure of a kind of novel not sticky lime-ash hopper of the utility model.

Detailed description of the invention

Consult shown in Fig. 1, a kind of novel not sticky lime-ash hopper, comprise hopper outside face 1 and hopper inside face 2, described hopper outside face 1 is provided with positioning bolt hole 3, described positioning bolt hole 3 is provided with more than one, and arrange in two rows on hopper outside face 1, described hopper inside face 2 is positioned at the below of hopper outside face 1, described hopper inside face 2 comprises chain and arranges rectangle 4 and chain 5, described chain arranges that rectangle 4 is positioned at the middle part on hopper surface 2, described chain 5 is arranged on chain and arranges in rectangle 4, described chain 5 is provided with one or more, two ends and the chain of described chain 5 arrange that the two ends of rectangle 4 are sewed up mutually.

Described positioning bolt hole 3 is provided with four, can fix with hopper at bucket elevator chain.

Described chain 5 is provided with 11, and is uniformly distributed, and after hopper uses chainlet to be uniformly distributed, enhances the surperficial elastic force of hopper, decreases metal viscous force.

Be separated by 1 centimetre between described every bar chain 5, be conducive to preventing mutual frictional impact between chain 5 from causing wearing and tearing.

Described every bar chain 5 has four links to interlink, with chain, the two ends being conducive to chain arrange that rectangle 4 phase is alleviated fixing.

The beneficial effects of the utility model are: use the improved hopper of the technology.Confirmed by on-the-spot real work, hopper Surface adhesion force is diminished, lime-ash enters water amount after hopper to be reduced, and bucket elevator is exerted oneself increase, extends the period of inspection and repair of bucket elevator, reduce maintenance cost.

The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in protection domain of the present utility model.
