Description

Totally enclosed type casting sand collator

Technical field

The utility model relates to a kind of improvement of casting sand collator, specifically a kind of totally enclosed type casting sand collator.

Background technology

Many metallic articles are all produced by casting, and casting process is earlier metal material to be heated to after fusing point becomes metallic solution, pours moulding in the moulding box of making of molding sand again into.The molding sand of its use is a quartz sand, and in order to reduce the casting cost, its molding sand will be reused, but formed piece with the molding sand of crossing, and contained binding agent, therefore, will carry out fragmentation to old molding sand before reusing, remove binding agent, making it become pure fine sand could use again.Owing to, in some small-sized foundry enterprises, still handle old molding sand for artificial process from economic consideration, but labor strength is big, efficient is low, and the molding sand quality of processing is relatively poor, does not also meet large-scale foundry enterprise and uses, therefore, it is necessary using the molding sand collator.Present molding sand collator generally comprises disintegrating apparatus, centrifugation apparatus, and described disintegrating apparatus comprises grinding equipment, mechanical vibrator equipment, the also employing water washing equipment that has; More than various collators, its weak point is: the one, complex structure, floor space be big, be not easy operation; The 2nd, expose operation, more, the contaminated environment of dust in fragmentation, binder powders also influences workers ' health in its fragmentation.

Summary of the invention

The purpose of this utility model is the totally enclosed type casting sand collator that a kind of operation simple in structure, easy is provided, do not produce environmental pollution.

For reaching above purpose, the technical scheme that the utility model adopted is: this totally enclosed type casting sand collator, by base, roller, motor, tilted supporter constitutes, it is characterized in that sending sand broken tube by tilted supporter on fixing on the base, sand shovel on the front end of base is fixing, send the lower end of the broken tube of sand to establish rotation suction sand mouth, send the fixing knockout case of going up of upper end downside of the broken tube of sand, at the fixing up-draught machine of a side of knockout case, soft storage dirt bag a knockout case side relative with hair-dryer is fixing, establish the molding sand storage and conveying box in the bottom of knockout case, on the roof that send the broken tube of sand, establish strip crevice, on the strip crevice by snap close fixing on the bar shaped cover, in the bar shaped cover, establish a magnetic roller, work as motor, after hair-dryer starts, this machine and sand shovel are pushed in the old molding sand, rotation suction sand mouth is about to old molding sand and sends in the broken tube of sand, old molding sand stirs in sending the broken tube of sand on one side, broken on one side, upwards carry on one side, the iron filings that in rotating pulverizing, occur, abrasive grit is adsorbed on the interior magnetic roller of bar shaped cover, make the iron filings in the old molding sand, abrasive grit is adsorbed away, and iron filings are removed in fragmentation, the old molding sand of abrasive grit is directly up sent into the knockout case, when broken good old molding sand passes the knockout case, adhesive dust broken in the sand is blown in the soft storage dirt bag because of in light weight, thereby remove the binder powders in the old molding sand, molding sand after the arrangement is again in falling into the molding sand storage and conveying box, can change normal use over to, old like this molding sand is through stirring, broken, deironing, the several operations of dedusting make old molding sand reach again the requirement of usefulness again.The utility model is also implemented by following measure: described broken of the sand that send, by cylindrical shell, central shaft, rigid bearing, send the sand spiral, broken bar construction, the upper end of central shaft is fixed on the upper end of cylindrical shell by rigid bearing, on segmentation on the central shaft is fixing, send sand spiral and broken rod, sending sand spiral and broken rod to intersect assembles, one group of broken rod is adorned in adjacent sending between the sand spiral, each section send the sand spiral to establish the 1-2 ring, each is organized broken rod and establishes 2, fixing along the equidistant welding of one week of central shaft, old molding sand is whenever carried in sending the broken tube of sand obliquely upward stirred one section beginning fragmentation once, old molding sand is carried in sending the broken tube of sand on one side, stir on one side, broken on one side, establish one section in the central shaft upper end and oppositely send the sand spiral, by oppositely sending the effect of sand spiral, old molding sand after the broken deironing is entered in the knockout case, and prevent that sand dust from entering in the bearing, fix bevel gear in the outer end of central shaft, bevel gear engagement with driven by motor, the bevel gear of driven by motor drives transmission by driving-belt, also establish bearing on the axle of the bevel gear of driven by motor, bearing is fixed by perpendicular support; It is the spiral suction inlet that the sand mouth is inhaled in described rotation, and its turning cylinder and central shaft are fixed as one; Described sand shovel is the dustpan shape, and the base plate face is the plane, and upper face is a cambered surface, and the oral area broad, and the width at rear portion is consistent with the diameter that rotates suction sand mouth.When using the utility model, as long as this machine is promoted forward, the sand shovel is pushed in the old molding sand, starter motor and hair-dryer can be put in order continuously to old molding sand.

The beneficial effects of the utility model are: compare with the various molding sand collators of present use, and simple in structure, floor space is little, easy operation control, and under whole sealing status, carry out work, and avoided environmental pollution, help workers'health.
