Description

The casting sand collator

Affiliated technical field

The utility model relates to the equipment that casting sand is put in order, refers in particular to a kind of casting sand collator.

Background technology

The casting method that has been widely used in making metal product is: heating of metal to its fusing point to form molten metal, molten metal is filled in the moulding box, this moulding box has and the identical profile of the desired metal product that obtains, and makes the molten metal cooled and solidified in the moulding box then.Being used for the moulding box that molten metal is molded and shaped is made up of molding sand, and the Main Ingredients and Appearance of molding sand is the quartz sand with very strong fire resistance.Enterprise usually reuses molding sand in order to increase economic efficiency, and reuses molding sand and must put in order used molding sand.Technology and operation that old molding sand is reused in arrangement have a lot, as: spray molding sand at high speed (1) to the district that mills.(2) in vibrating device, old molding sand is carried out mechanical oscillation by means of air stream.(3) wash old molding sand with water.(4) old molding sand is charged in the rotatable tube of milling handles.

Chinese patent once disclosed a kind of " sand reclamation device " (ZL87103119, open day: 1988.11.09), its composition had: the sand elevator; The solid and gas separator that the dust air is discharged usefulness that contains that is reproduced sand by this sand elevator feed; The regenerator that is reproduced sand regeneration usefulness of discharging by this solid and gas separator; Be contained in the conversion groove of the handle of this regenerator outlet side from the discharge direction restriction usefulness of the sand of regenerator discharge; The hopper that is connected with the sand elevator with a side's of the above-mentioned conversion groove of being contained in of valve discharge side is equipped with in the bottom; Be contained in the opposing party's of above-mentioned conversion groove the reclaimed sand container of discharge side.

That Chinese patent also once disclosed was a kind of " recycling the method and the equipment thereof of molding sand " (application number: 02155808.6, open day: 2003.05.07), the bulk molding sand that pulverizing separates from moulding box, thereby obtain old molding sand, stick to the lip-deep binding agent of old molding sand in order to remove, after in old molding sand being charged to the cabinet that the rotatable tube of milling is installed, be rotatably installed in the impeller on the rotatable tube of milling.After on the impeller that old molding sand is charged in the cabinet,, and, dispose the binding agent that is bonded at old molding sand surface by means of the revolving force of impeller because the collision of milling between the tube of molding sand and rotation contacts with mutual friction rolling.Then will be from old molding sand isolated binding agent fine powder and the extraneous air that enters cabinet from the inlet tube that has motor and be positioned at the rotating shaft at cabinet middle part together, collect by dust and mouthful to drain.

Owing to economy and practicality reason, above-mentioned technology and equipment can not get using widely.At present, most of foundry enterprise still all is by artificial sieve or manually carries out screen with spade one spade one spade ground spade in mechanical eccentric wheel construction sieve tool.Labor strength is big, and efficient is low, and molding sand quality is also bad, and humidity is uncontrollable.Blow-on iron water amount of small-sized foundry enterprise is about 10 tons, and the molding sand that needs usefulness adopts said method also might finish in one day about 30 tons.And the enterprise that reaches about 150 tons, in a day, must will handle 300-500 ton left and right sides molding sand for blow-on iron water amount, the workman again can not all carry out screen to whole place, can only turn over spade after watering, cast(ing) surface can only solve with the part facing sand, molding sand quality (humidity, gas permeability) is difficult to guarantee that product (foundry goods) quality also just is difficult to guarantee.Foundry enterprise generally all is that first day after blow-on will go out the moulding place to the foundry goods complete liquidation, will put casting sand can reuse in order in one day, and second day will moulding, and not so the blow-on cycle can't be caught up with and be influenced the business economic benefit.

The utility model content

The purpose of this utility model is to provide a kind of casting sand collator, and it can be put in order used molding sand at the scene, and the molding sand of putting in order can be reused.

For achieving the above object, the solution that the utility model is taked is: a kind of casting sand collator, one motor drives driving wheel, driving wheel drives a center heavy burden follower, this center heavy burden follower burden base plate/support, this base plate/support only is placed with spiral and promotes bucket, this spiral promotes barreled in a main shaft lower end, this main shaft upper end is with the overcoat main shaft, the centrifugal emery disc that gets rid of is equipped with in this overcoat main shaft lower end, main shaft and overcoat main shaft are by main driven by motor, and a lower sand barrel is enclosed within spiral and promotes the bucket outside, and this lower sand barrel lower end has sand inlet, correspond to sand inlet the colter mouldboard is housed, be upper sand barrel on the lower sand barrel, the upper sand barrel upper end has sand export, rotatable separately 360 ° of lower sand barrel and upper sand barrel.

The principle that the utility model utilizes the colter mouldboard to plough a field is in the on-the-spot use of moulding.Machine is advanced under the rotation impetus of driving wheel, the colter mouldboard has entered the old molding sand scarifying of front the sand inlet of lower sand barrel, promote bucket by spiral and rise to the centrifugal emery disc that gets rid of incessantly, constantly old molding sand being thrown away another side from the sand export of upper sand barrel under centrifugal effect of getting rid of emery disc does not have molding sand district (moulding district).Machine by constantly rotate, stirring, high speed centrifugation hit even getting rid of and a series of positive actions such as push away, and old molding sand is put in order completely, guaranteed the gas permeability of type.Because rotatable separately 360 ° of lower sand barrel and upper sand barrel, machine can be advanced back and forth, and the old molding sand at scene is put in order, and the old molding sand of putting in order can be reused.
