Description
Technical field
The present invention relates to Casting Equipment of Machine technical field, particularly to a kind of puddle mixer and mulling method.
Background technology
In green-sand casts, the quality direct relation of molding sand the quality of foundry goods, is related to the height of casting wasted product rate,
Along with the development of modern style technology, the molding sand amount of needs is increasing, and sand the most maximum processes, it is desirable to per hour
1000 tons of molding sand are provided.This just proposes the highest requirement to the equipment-puddle mixer being blended molding sand.
Before eighties of last century eighties, puddle mixer mainly uses simpson mill, and simpson mill grinds due to it
Rolling and stranding effect of wheel, the molding sand quality being blended is good, but its mixed grind one dish-type sand needs more than 5 minutes.But it is as
Requiring that puddle mixer is blended molding sand and gets more and more, mulling in each hour is from 15 tons-20 tons, and it is main for developing into 80-120 ton, mixes individually
Sand machine is even up to 300 tons.It is longer that simpson mill is primarily due to the mixed grind time, and efficiency is low；Secondly because muller is to power
Requirement high, muller can not infinitely be manufactured greatly, it is impossible to producing the biggest puddle mixer, energy consumption is big；The molding sand that last muller rolls out
Often with a lot of sand beans or stiff bean, affect molding sand quality；Therefore simpson mill has progressively exited market.From eighties of last century
The nineties, rotator mixed sand machine becomes the leading products in puddle mixer market.Rotator mixed sand machine utilizes the high-speed rotary of rotor
Turning so that the bulk sand material of condensation is blended and mix homogeneously, stiff bean greatly reduces, and the molding sand mixed out loosens handy.And turn
The minor puddle mixer general mixed grind time, mulling efficiency was high all within 2 minutes.But the principle due to rotator mixed sand machine mulling
Being to stir and smash, do not roll and kneading action, therefore Quality of Mixing Sand is not so good as simpson mill.Do not roll and rub with the hands,
Therefore bentonite attachment on quartz sand is insecure, and under kindred circumstances, molding sand green compression strength is mixed out less than simpson mill
Molding sand.
The most conventional puddle mixer is typically horizontally or diagonally to be arranged, rotor mechanism therein is vertical direction and arranges
In puddle mixer, even if coordinating the additional structure such as scraping plate mechanism to be stirred, but the inside of puddle mixer the most easily occur long-pending sand,
, there is mulling dead angle in the situations such as scab.And long-pending sand time longer sand lump is hardening, it is more difficult to again being blended, once coming off is mixed into

The best.Therefore return sand cooling is in southern high-temperature and high humility area, has become the most scabrous quagmire.For solving this problem,
American-European countries, particularly Ai Lixu company of Germany, be proposed vacuum cooled puddle mixer, uses the way in vacuum environment cooling,
Owing to, under vacuum environment, the boiling point of water reduces, amount of heat is taken away in the volatilization of large quantity of moisture, and used sand temperature declines rapidly.But its
Only carry out vacuum cooled, and puddle mixer is a moving component, a moving component will be implemented evacuation and seal the most tired
Difficulty, therefore vacuum sand mixer is expensive, and operating cost is the highest, the price of a puddle mixer, often beyond tradition puddle mixer and
The summation of the price of sand cooling device, causes Difficulty so far.
While substantial amounts of dust is taken out in dedusting in existing mulling, also take out substantial amounts of bentonite and coal dust, cause auxiliary
Material loss.
