Description
Technical field
The utility model belongs to the device of foundry engieering, is specifically related to casting old-sand regeneration equipment.
Background technology
The used old sand of Foundry Production must be handled through regeneration, peels off bonding between the sand grains and is attached to the adhesive film of sand grain surface, just can reuse.In the existing sand reclaiming plant, be a kind of associating of multiple devices mostly and work continuously, the utility model patent spiral vibrating reclaiming machine for waste sand that ZL99223572.3 provided, it makes multiple devices regeneration become an equipment regeneration, and the change continous way is batch (-type).It by vibrating motor, external spiral, cylindrical shell, add sand mouth, exhaust outlet, sand export, air intake tube and base etc. and form, external spiral is set with sleeve outward, the cylindrical shell inner bottom part is equipped with conical bottom, the sand block air dispersion plate is housed on the conical bottom, screen is housed above the conical bottom, the center tuyere is housed on screen and the conical bottom, and the air intake tube stretches in the conical bottom, and exhaust outlet is equipped with in the sleeve upper end.This device structure is complicated, and old sand rotatablely moves in cylindrical shell, the remanufactured component serious wear, and also energy consumption and noise are all higher.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, energy consumption is low, high efficiency self-friction (sand) reclaimer.The palingenesis of this equipment is mainly used be between the sand lump from the phase rubbing, do not have special regeneration member in the equipment, thereby reduced the wearing and tearing of equipment; Adopt closed selection by winnowing design, reduced dust effusion regenerating device, meet the requirement of modern green foundry
A kind of vibration (sand) reclaimer of the present utility model, form by the cylindrical shell and the vibrating motor that are supported on the spring, cylindrical shell top has the sand of adding mouth, the interior bottom of cylindrical shell that sieve plate is housed, it is characterized in that (1) cylindrical shell shape of cross section is a regular polygon, 3-12 is counted on the limit, and (2) cylindrical shell axis is installed the exhaust column that runs through sieve plate, and the cylindrical shell bottom is communicated with the selection by winnowing funnel, (3) vibrating motor is two, is installed on barrel outer surface with axial symmetry in the cylindrical shell.
Described vibration regenerating used loading amount, it is further characterized in that: the sieve plate installation position is higher than the cylindrical shell bottom in (1) cylindrical shell, forms the selection by winnowing chamber, (2) two vibrating motor axis are not parallel to each other, mutually out of plumb, become 20～70 ° of angles with horizontal plane respectively.
Described vibration (sand) reclaimer, inner barrel can install abrasion-proof backing block additional, only part surface punching of sieve plate.
Described vibration (sand) reclaimer, two vibrating motor axis preferably equate with horizontal plane angle, are 30～60 °.
In the device of the present utility model, the regeneration tube adopts polygonized structure (referring to accompanying drawing).Can limit sand lump rotatablely moving under the turning moment effect like this, thereby reduce the wearing and tearing of sand lump to greatest extent regeneration tube sidewall and base plate, and the mutual frictional force between aggravation old sand piece or sand grains.The oscillatory torque that produces vertical axis during the vibrating motor operation adds the vibration force of vertical direction, and the sand lump in the driving regeneration tube is from friction mutually.This device integrates the fragmentation of old sand, the functions such as membrane removal, dust removal of pneumatic separation of regenerating, and belt conveyor is sent into the old sand piece in the regeneration tube of regenerating device from the top of regenerating device; Broken, the membrane removal in the regeneration tube of old sand piece; The loose sand grain selection by winnowing chamber of bleeding in the bottom aperture of regeneration tube, and selection by winnowing dirt pipe is sitting at the top middle portion of selection by winnowing chamber; The sand grains of regeneration falls into belt conveyor from the lower end of regenerating device, and this design makes the regenerating used production line simple and compact for structure.Equipment self is simple in structure, take up an area of less, Installation and Debugging are easy.
Description of drawings:
Fig. 1 is the utility model device schematic diagram,
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Represented device among Fig. 1 and Fig. 2 is made up of the liner plate in polygon cylindrical shell 1, the cylindrical shell 2, vibrating motor 3,10, sieve plate 4, spring 5, selection by winnowing funnel 6, base 7, exhaust column 11, and selection by winnowing chamber 8 is arranged at cylindrical shell 1 bottom, has slag notch 9 on the cylindrical shell.
In practical process, at first start belt conveyor, the old sand piece is sent in the regeneration tube (1), when the old sand piece reach regeneration tube volume 2/3 the time, Vibration on Start-up motor (3), (10) and centrifugal exhauster, regenerating device entry into service.Old sand is broken, rubbing in regeneration tube (1), and sand grains is owing to rubbing action breaks away from from sand group.These sand grains are fallen on the extraction plate (4) of regeneration tube by top, the middle part of regeneration tube.Because the effect of turning moment, sand grains be in the rotation limit friction of extraction plate top, when through the aperture on the sieve plate, the selection by winnowing of bleeding chamber (8), and selection by winnowing funnel (6).Under the swabbing action of air exhauster, enter the sand grains of selection by winnowing chamber and selection by winnowing funnel and up air-flow and meet, form photographic fog, bonding agent dust and the less sand grains of order number are sucked away.Sand grains after the selection by winnowing drops on the magnetic separation belt, in course of conveying the splashings in the sand grains is removed, and it is standby to send into sand hopper through the sand of cleaning.After regenerating device work a period of time (3～5 days), open except that cinder notch (9) will regenerate the tube in foreign material clean out, in order to avoid influence reproduction speed.
