Description
Technical field:
The present invention relates to a kind of cantilever type movable dust hood.
Background technology:
In the production process of large mold, when carrying out the casting and pouring of mould, the high-temperature metal liquation is when being poured into sandbox, core rod melts burning, produce a large amount of volatile matter and flue gas, upwards gush fast and spread, the time is about 30 minutes, is to guarantee workpiece quality, to wait for nearly 24 hours after the cast and wait metal freezing, can be with sandbox and poured into a mould workpiece and hung away, therefore in process of production, each enterprise all plans a plurality of fixed points cast stations, flue gas during for this technique cast is processed, it is extremely important to design a kind of draught hood, discharges direction according to flue gas, draught hood is set for best at the top, but pour point top headroom is Hoisting Position, the pour point sidepiece is the operating position in when cast, and the size of draught hood need design greatlyr, normally covers open area and is at least 7 meters * 5 meters.Therefore factory does not arrange draught hood at this station, does not have the ventilation and dust removal device, causes the seriously polluted of job site and whole workshop.
In the production and smelting process of special alloy material and rare metal, need a large amount of electric arc furnaces that adopt, a large amount of flue gases is arranged and carry the particle ejection in the high arc temperature smelt stage, 10～40 minutes time, the body of heater top is charging zone and electrode insert district, positive front side is the blowing workspace, two zones all can not arrange fixed top draught hood, generally be provided with many electric arc furnaces in a workshop, its high arc temperature smelt stage is staggered, at present factory does not arrange dust excluding hood at this station, seriously polluted to job site and whole workshop.
In large-scale plumbous smeltery, there are 10～20 lead melting furnaces arranged side by side in each molten lead workshop.The effect of lead melting furnace is that lead bullion is melted, and electrolysis technique positive plate casting mold is used.The diameter of lead melting furnace is about 3.0m.About 550 ℃ of plumbous melt temperature.In the production process, the lead melting furnace liquid level that has produces scum silica frost, need to pull out; The lead melting furnace that has needs when working to stir; Anode scrap will come back in the market pot and melts after electrolysis in addition, aforesaid operations is to utilize driving to carry out on market pot top, the flue gas of discharging in this operating process is mingled with a large amount of nuisances, and the nuisance main component is plumbous and plumbous oxide, and is larger on the impact of environment.Exhaust hood carries out air draft because operating feature and the maintenance characteristics of market pot, its top do not allow to arrange fixedly, and this has brought many unfavorable factors to Design of ventilation, and for a long time, the ventilation of market pot becomes the hard nut to crack in the design.Factory carried out practice and research to market pot side air draft mode at present, because the market pot diameter is larger, and exists the cross-flow interference in workshop, required exhaust air rate very large, and result of use is also not ideal enough.
Summary of the invention:
