Abstract
The invention relates to a dust collecting device, in particular to a collecting and exhausting device for cast dust produced in a large-scale steel casting production process. The collecting and exhausting device for the cast dust produced in the large-scale steel casting production process is characterized by comprising ash-exhausting points connected in series, all the ash-exhausting points are connected with one side of a material-gas separator through an ash conveying main pipeline, the other side of the material-gas separator is connected with a roots pump through an air inlet pipeline, and the lower portion of the material-gas separator is connected with an ash storage bucket. The collecting and exhausting device for the cast dust produced in the large-scale steel casting production process can solve the secondary dust-raising problem produced during the exhausting process of the dust, reduce the labor intensity of staff, improve working efficiency and reduce maintenance cost.
Description
Technical field
The present invention relates to a kind of dust collecting, especially relate to the collection tapping equipment of the Foundry producing in a kind of large-scale steel-casting production process.
Background technology
In the production process of steel-casting, in order to reach the nonexpondable object of molding sand, the molding sand after cast will pass through the links such as knockout, regeneration, separation and carry out dust removal process; The operations such as the rising head cutting that foundry goods carries out in preorder, gouge can produce a large amount of metallic dusts, make a general survey of domestic and international casting industry, to the collection method of these dust, adopt the high-power fiber bag precipitator of monomer to collect more, again by driven by motor reel, the ash content of collection is pushed to feed opening, storage ash bucket is put in feed opening below, Deng storage after ash bucket expired, change again an empty ash bucket and continue storage ash, recycling replacing ash bucket like this, finally, concentrate and to pour the ash in ash bucket into the outer row that pulls out in ash discharge vehicle.There is following shortcoming in this method: 1) ash discharge point disperses, and the ash bucket of use is many; 2) dust is first arranged into ash bucket by reel, then arranges into drawing in the process of grey vehicle and have a large amount of airborne dusts, serious environment pollution; 3) each ash discharge workload is large, at least needs two people's operations.
Up to the present, also do not overcome the device of above-mentioned defect.
Summary of the invention
The object of the invention is to overcome the defect of prior art, provide a kind of and can solve reentrainment of dust problem that dust produces in discharge process, reduce staff labor intensity, increase work efficiency, reduce the collection tapping equipment of the Foundry producing in a kind of large-scale steel-casting production process of maintenance cost.
The present invention realizes in the following way:
The collection tapping equipment of the Foundry producing in a kind of large-scale steel-casting production process, it is characterized in that: it comprises the ash discharge point being cascaded, all ash discharge points are by sending grey main pipeline to be connected with material gas separating device one side, material gas separating device opposite side is connected with lobe pump by admission line, and material gas separating device bottom is connected with storage ash bucket;
Described each ash discharge point is all dischargers of being installed successively by ash discharge reel, ash discharge reel below, excessively bucket and Wen's discharger assemble;
In described excessive bucket, pneumatic gate valve and level-sensing device are installed.
The present invention has following effect:
1) can solve reentrainment of dust problem that dust produces in discharge process, and can reduce staff labor intensity: it comprises the ash discharge point being cascaded device provided by the invention, all ash discharge points are by sending grey main pipeline to be connected with material gas separating device one side, material gas separating device opposite side is connected with lobe pump by admission line, and material gas separating device bottom is connected with storage ash bucket; Described each ash discharge point is all dischargers of being installed successively by ash discharge reel, ash discharge reel below, excessively bucket and Wen's discharger assemble; The negative pressure of utilizing roots blower to produce, drive flowing of the interior air of pipeline, the ash of discharging from ash discharge point enters negative-pressure pipeline, the air-flow producing along with suction function enters gas-material separator, air is gone out by the cloth bag in gas-material separator, and ash content is stayed on cloth bag, by being contained in the compressed air back-flushing valve on cloth bag, the ash content of staying on cloth bag is blown off into ash entrance chamber, concentrate discharge.
2) increase work efficiency, reduce maintenance cost: device provided by the invention is installed excessively bucket below the discharger of ash discharge reel, excessively below bucket, Wen's discharger is being installed, Wen's discharger is connected with far-end material gas separating device, storage ash bucket is installed, lobe pump is installed, each point is coupled together, realize dust centralized collection, the excessive bucket of each ash discharge point below is installed to pneumatic gate valve, excessively in bucket, level-sensing device is installed, when the high charge level of excessive bucket is reported to the police, trigger lobe pump, send in grey main pipeline and be full of negative pressure, excessively the ash content in bucket is along with negative pressure enters material gas separating device, by the filtration cloth bag in material gas separating device, ash content is stoped on cloth bag, fall into storage ash bucket, concentrate outer row, not only can increase work efficiency, also reduced ash bucket because repeatedly ash discharge causes the maintenance cost of damage.
3) device provided by the invention can be put minute warehousing such as resin ash, gouge calx, rising head cutting metal ash, waste residue, has facilitated focusing on of ash content;
4) device provided by the invention has been saved ash discharge, has been changed fuel oil expense, vehicle maintenance expense that ash bucket uses vehicle to produce.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of each ash discharge point of the present invention.
The specific embodiment
The collection tapping equipment of the Foundry producing in a kind of large-scale steel-casting production process, as shown in Figure 1: it comprises the ash discharge point 8 being cascaded, all ash discharge points 8 are by sending grey main pipeline to be connected with material gas separating device 5 one sides, material gas separating device 5 opposite sides are connected with lobe pump 7 by admission line, and material gas separating device 5 bottoms are connected with storage ash bucket 6.
As shown in Figure 2: described each ash discharge point 8 be all the discharger 2 installed successively by ash discharge reel 1, ash discharge reel 1 below, excessively struggle against 3 and Wen's discharger 4 assemble.
In described excessive bucket 3, pneumatic gate valve and level-sensing device are installed.
