Description
Technical field
This utility model relates to casting field, is specifically related to a kind of casting and pulls out slag dust arrester.
Background technology
Foundry is dirty, random to the impression of people, and foundry's dust pollution is serious.In foundry not only shake out knockout, return sand conveying, discharging, old sand bucket proposes discharging, the moulding such as old sand screening, cooling, lifting warehouse-in, mulling, sand process the airborne dust point of the Ministry of worker can produce dust, pulls out at molten casting iron fusing smelting process such as molten iron and also can produce a large amount of slag dirt in the operations such as slag.These slag dirt are the residual sand granule of the scaling loss that red heat cast(ing) surface comes off, the impurity of bentonite, coal dust, molten iron raw material surface and inside that is burnt or dried by foundry goods, and the flue dust etc. that coal dust firing produces, temperature is up to 59 150%, and with a large amount of water vapour.It is very serious to the destruction of environment to be discharged in environment, and the healthy of workman of foundry is caused serious threat.
At present, cleaner obtains the extensive use of society, reaches the purpose of environmental protection.But molten casting iron pulls out slag dedusting project, owing to many-sided reason is facilitated, it does not have form good dust pelletizing system, and become a difficult problem of casting environmental protection aspect.Labor intensity when pulling out slag is too big, and high temperature heat wave such as cannot avoid to exist at the phenomenon.Green environmental protection casts, and has listed in national development planning.How to solve pulling out slag dedusting, pull out slag labor intensity, pull out the problems such as slag high temperature, be the pursuit of each Foundry Works.
Utility model content
This utility model is intended to provide a kind of casting to pull out slag dust arrester, pulls out slag labor intensity to reduce, reduces and pull out the pollution to environment of the slag slag dirt.
For reaching above-mentioned purpose, basic technology scheme of the present utility model is as follows: slag dust arrester is pulled out in casting, including aerator, heat shield, dust shield, air exhauster.Described aerator connects with the lower end of heat shield, and described dust shield is fixed on the top of heat shield.Described air exhauster is fixed on the top of dust shield, and described air exhauster has water separator, the upper end of described water separator to be fixed with water tank by pipeline communication, and the gas outlet of described water separator is communicated with sack cleaner.The inwall on described water separator top is provided with some vertical nozzles, and described nozzle connects with water tank.
Principle and the advantage of this programme be: during operation, carry out pulling out slag in heat shield, in heat shield, air is blasted by aerator, the slag dirt pulling out slag generation is delivered in water separation device by dust shield and air exhauster, most slag dirt is precipitated by water separation device, and residual volume is little, the slag dirt of light weight is admitted to sack cleaner and carries out dedusting.Arrange heat shield can be isolated by the high temperature heat wave of molten iron, make operator to work in hot environment for a long time, improve working environment, reduce labor intensity, make casting pull out slag convenient.Water separator is set and the high temperature sludge dust and gas stream pulling out slag generation can be carried out cooling-sedimentation, remove the major part slag dirt that volume is big, quality is big, remaining slag dirt is filtered after being lowered into sack cleaner by the slag dirt gas flow temperature after water separator cooling-sedimentation, will not cause damage because of the too high filter bag to sack cleaner of temperature.Arranging nozzle on water separator, in nozzle, the water smoke of ejection is attached on the slag dirt in high temperature sludge dust and gas stream and makes slag dirt settle.The slag dirt that casting can be pulled out slag generation by devices such as heat shield, air exhauster, water separator and sack cleaners by this programme is filtered recycling, reduces slag dust and gas and flows to the discharge of environment, reduces the pollution to environment；The hyperthermia radiation pulling out slag process can be completely cut off, reduce operator's labor intensity, make casting pull out slag convenient, more environmentally-friendly.
Preferred version one, based on a kind of improvement of scheme, the bottom of described water separator is funnelform slag-drip opening, slag-drip opening be connected with slag trapping box.So arrange the slag dirt of sedimentation and the current of cohesion in water separator to be flowed in slag trapping box by slag-drip opening and recycle, will not to environment
Preferred version two, preferably a kind of improvement of, a sidewall of described heat shield is provided with transparent observation window, and the thermal insulation board below observation window is provided with two action bars side by side.Arranging transparent observation window on heat shield facilitates operator's immediate observation to pull out the progress of slag, arranges action bars and facilitates operator manually to assist to pull out slag, so arranges more convenient operator and control timely to pull out slag process.
Preferred version three, preferably a kind of improvement of two, the air inlet of water separator is separately positioned on gas outlet on two sidewalls that water separator is relative, and described air inlet is positioned at upper end, and described gas outlet is positioned at lower end.So arrange and make the slag dust and gas stream of entrance sack cleaner temperature after sedimentation was relatively low, the less air-flow of slag dirt in order to enter, reduce the load of sack cleaner, make the filter bag of sack cleaner be not easily blocked, make the longer service life of sack cleaner.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: aerator 1, heat shield 2, dust shield 3, air exhauster 4, pipeline 5, water tank 6, water separator 7, sack cleaner 8, action bars 9, observation window 10, shower nozzle 11, slag trapping box 12.
Embodiment is substantially as shown in Figure 1: slag dust arrester is pulled out in casting, including aerator 1, heat shield 2, dust shield 3, air exhauster 4.Described aerator 1 connects with the lower end of heat shield 2, and described heat shield 2 is uncovered rectangular box-like in the upper end that thermal insulation board surrounds.One sidewall of described heat shield 2 is provided with transparent observation window 10, observation window 10 be connected with two action bars 9 side by side.Described dust shield 3 is fixed on the top of heat shield 2, and described dust shield 3 is up-small and down-big isosceles trapezoid shape.Described air exhauster 4 is fixed on the top of dust shield 3, and the outfan of described air exhauster 4 is communicated with water separator 7 by pipeline 5, and the upper end of described water separator 7 is fixed with water tank 6, and the gas outlet of described water separator 7 is communicated with sack cleaner 8 by pipeline 5.The air inlet of described water separator 7 is positioned at upper end, and gas outlet is positioned at and the lower end of air inlet opposite side.The inwall on described water separator 7 top is provided with some vertical nozzles, and described nozzle connects with water tank 6.The bottom of described water separator 7 is funnelform slag-drip opening, slag-drip opening be connected with slag trapping box 12.
