Abstract

The utility model belongs to the technical field of dedusting of a concrete mixing plant, and particularly relates to a dust zero discharge concentrated treatment device for the concrete mixing plant. The dust zero discharge concentrated treatment device for the concrete mixing plant comprises powder collecting pipes (1), dust distribution hoppers (2), conveying pipelines (3), a deduster (4) and dust conveying equipment (5), wherein the powder collecting pipes (1) are communicated with corresponding powder bins and the dust distribution hoppers (2); the bottoms of the dust distribution hoppers (2) are connected with the deduster (4) by the conveying pipelines (3); and the deduster (4) is communicated with a powder metering hopper by the dust conveying equipment (5) at the bottom. The dust zero discharge concentrated treatment device is hung above a main concrete mixing plant; dust is collected and used in a sealed manner in a whole process; the whole process cannot be intervened artificially; the dust does not drop or spill for a second time; and purposes of zero discharge and recycle of the dust are achieved.

Description

Concrete mixing plant dust zero discharge centralized processor

Technical field

The utility model belongs to a kind of concrete mixing plant dedusting technology field, is specifically related to a kind of concrete mixing plant dust zero discharge centralized processor.

Background technology

Concrete mixing plant concentrated dust-removing mode is at present: the dust on each filler bin top is collected by the dust pipe, by dust collecting bucket and dust transfer pipeline, entering on the ground configuration dedusting room or tank body collects, the dust that certainly will collect like this needs further after-treatment, so just causes the generation of dust secondary pollution problem.

The utility model content

The purpose of this utility model proposes a kind of concrete mixing plant dust zero discharge centralized processor at existing weak point in the above-mentioned prior art just, to dust collect, dedusting, and the dust of collecting is delivered directly in the production run system, solve the secondary pollution defective that the concrete mixing plant dedusting exists in the prior art.

The purpose of this utility model realizes by following technique measures:

Concrete mixing plant dust zero discharge centralized processor of the present utility model includes: powder collecting pipe, dust distribute bucket, transfer pipeline, deduster and dust conveying equipment; Described powder collecting pipe is arranged on the filler bin top, described powder collecting pipe is communicated with corresponding filler bin and distributes bucket to be communicated with described dust, described dust distributes bucket to be mounted with the advance grey interface identical with filler bin quantity, and respectively with the powder collecting pipe connection of the corresponding filler bin of institute; The dust of each filler bin of centralized collection; The dust collection of filler bin is distributed bucket to described dust; Described dust distributes the bottom of bucket to link to each other with described transfer pipeline, links to each other with described deduster by described transfer pipeline; Described deduster is communicated with the powder weighing hopper by the described dust conveying equipment of bottom; The dust that filters through described deduster is sent to the powder weighing hopper by the dust conveying equipment, makes the dust of collection enter production system and uses.

Dust conveying equipment described in the utility model is airslide or screw machine.

Deduster described in the utility model is equipped with safety valve, discharges in order to the gas that the dust-precipitator internal pressure is excessive.

The beneficial effects of the utility model are as follows:

A kind of concrete mixing plant dust zero discharge centralized processor that the utility model proposes, to dust collect, dedusting, and the dust of collecting is delivered directly in the production run system, the equal non-secondary pollution of whole dust does not need manually-operated.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure; 1, powder collecting pipe, 2, dust distributes bucket, 3, transfer pipeline, 4, deduster, 5, the dust conveying equipment, 6, safety valve.

The specific embodiment

The embodiment that provides by reference to the accompanying drawings is illustrated the utility model:

As shown in Figure 1, concrete mixing plant dust zero discharge centralized processor, described gathering-device include powder collecting pipe 1, dust distributes bucket 2, transfer pipeline 3, deduster 4, dust conveying equipment 5 and safety valve 6; Described powder collecting pipe 1 one ends stretch to inside from the filler bin top, on the powder car is in the filler bin in the grey process, the dust of kicking up in the filler bin is by powder collecting pipe 1, centralized collection is distributed in the bucket 2 to dust, described dust distributes bucket 2 to be mounted with the advance grey interface identical with filler bin quantity, and respectively with powder collecting pipe 1 connection of the corresponding filler bin of institute; The dust of each filler bin of centralized collection; Described dust distributes the bottom of bucket 2 to link to each other with transfer pipeline 3, dust distributes bucket 2 outlet at bottoms to enter in the transfer pipeline 3 by dust, transfer pipeline 3 other ends are directly connected to deduster 4 ash inlets, dust enters in the deduster 4, described deduster 4 inside are selected for use and are pulse air-blowing filter bag type deduster, dust filters by the filter bag in the deduster, clean air is discharged in the air by around the dust remover roof, dust on the filter bag regularly blows filter bag with pressure-air by pulser control compressed air, the dust that is blown off is scattering into the deduster bottom, deduster 4 bottoms are connected with dust conveying equipment 5, and dust conveying equipment 5 is transported to dust in the powder weighing hopper and measures use.5 configurations of dust conveying equipment are adopted as screw machine or two kinds of forms of airslide, and specifically selecting type for use is to determine according to the version of concrete mixing plant.

Concrete mixing plant dust zero discharge centralized processor described in the utility model, hang on the concrete mixing plant main website, by adjusting transfer pipeline distribution form, deduster installation site, airtight dust collection is used of dust conveying equipment overall process, overall process can not have artificial intervention, the phenomenon that no secondary dust is shed, overflowed reaches the purpose of dust zero discharge, recycling.
