Abstract
The invention relates to an investment cast shell crushing, grading and screening system comprising a vibration cleaning and shakeout mechanism, a grinding and crushing mechanism, a gear pair rolling mechanism and a grading and screening mechanism which are connected through a conveyer belt. When mould sand is cleared, an investment cast is arranged on the vibration cleaning and shakeout mechanism; the mould sand outside the cast is vibrated to a shakeout collection hopper, conveyed into the grinding and crushing mechanism and the gear pair rolling mechanism, so that large caked mould sand can be crushed; and the mould sand is conveyed to the grading and screening mechanism to be graded and collected according to the sizes of the mould sand particles after being crushed. According to the mould sand grading and screening system in the structure, an assembly line which carries out sand cleaning, shakeout, crushing and screening processes on the investment cast automatically, no manual operation is needed, so that the mechanical automation degree is high, the working efficiency and the reuse rate are greatly improved, the labor intensity of a worker is reduced, dust is not scattered, and green manufacturing, environmental protection and sustainable development are realized.
Description
Technical field
The present invention relates to a kind of screening plant, the device of moltening mold castings shell is reclaimed in particularly a kind of gradable screening.
Background technology
" lost-wax casting " claimed in model casting again; Typically refer at fusible material and process apperance, coat the several layers refractory material on the apperance surface and process shell, again shell is discharged in the apperance fusing; Thereby obtain the casting mold of no die joint, after high-temperature roasting, get final product the founding method of back-up sand cast.Be applicable to produce complex-shaped, required precision is high or the miniature parts that is difficult to carry out other processing, like the blade of turbogenerator etc.Investment-casting need be removed molding sand from foundry goods after casting is accomplished, the sand mold of removing need pass through sand removal, knockout, fragmentation and sorting operation, realizes the recycling of molding sand at last.According to actual conditions describe conventional method with and shortcoming: for example: traditional method adopts workman's cleaning, because sorting is lack of standardization during cleaning, molding sand recycling rate is not high, causes the waste of resource.Workman's operating efficiency is slow, and dust and noise are big, and workman's physical and mental health is had very big influence.And discarded molding sand contains harmful chemical, can contaminated soil, as the edaphophyte that spreads this molding sand can't grow, thus improve this molding sand reclamation rate, all significant to environmental protection and sustainable development.
Summary of the invention
The technical problem that the present invention will solve provides the device that the moltening mold castings shell is reclaimed in a kind of gradable screening.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of investment casting shell fragmentation and sizing screening system is characterized in that: comprise a shake-out knockout mechanism, it comprises a screen cloth; On this screen cloth vibrator is installed, the bottom of screen cloth is provided with the knockout collection bucket; One grinds crushing mechanism, comprises abrasive sheet, and this abrasive sheet is provided with by motor-driven vertical rotation axis, and rotating shaft is provided with at least one roller, and the abrasive sheet below is established the knockout collection bucket equally; One gear mesh roller structure comprises tooth rest, and a pair of pitch wheel is installed on this tooth rest, and the knockout collection bucket is established in the below of tooth rest; A sizing screening mechanism comprises at least two identical and screen cloth conveyer belts that connect successively of structure, and the vibrator of vibration vertically is installed on the power transmission shaft of screen cloth conveyer belt, all establishes under each screen cloth conveyer belt with classification and connects the atresia conveyer belt that sandbox is connected; Said shake-out knockout mechanism, grind between crushing mechanism, gear mesh roller structure and the sizing screening mechanism and all connect through conveyer belt.
Further, be provided with a sealed preventing dust blimp outside said grinding crushing mechanism, gear mesh roller structure and the sizing screening mechanism.
Further, on the said sealed preventing dust blimp dust absorption plant is installed, its structure is: comprise the inlet scoop, be provided with a screen pack in the place ahead, inlet scoop, this screen pack front lower is established sand export.
Further, connect the screen pack vibrator on the said screen pack.
Further, be equipped with guide post between two gears of said gear mesh roller structure and the tooth rest, this guide post and tooth rest are slidingly matched, and the spring of gear being pressed to another gear is installed on the guide post.
Further, said atresia conveyer belt also can be replaced by the grooved guide plate that tilts.
The invention has the advantages that: during the cleaning shell; Investment-casting is placed in the shake-out knockout mechanism; Shake by the screen cloth molding sand that foundry goods is outer and to drop down onto in the knockout collection bucket; It is broken to be delivered to the molding sand that in grinding crushing mechanism and the gear mesh roller structure bulk is bondd by conveyer belt, is delivered to after the fragmentation in the sizing screening mechanism, on the atresia conveyer belt below most of molding sand greater than this sieve number falls under the effect of screen cloth conveyer belt; And have classification to connect sandbox to collect, remaining molding sand is delivered to another terminal classification by the screen cloth conveyer belt and is connect sandbox and collect or proceed sorting by another sizing screening mechanism.The screen cloth conveyer belt can drive down at roller on the one hand and forward, and one side shakes on the direction vertical with direction of transfer through electromagnetic shaker, and is effective, noise is low.
Adopt the molding sand sizing screening system of this structure; Constitute a streamline that carries out sand mold sand removal, knockout, fragmentation and the sorting process of investment-casting automatically, need not to carry out manually, the mechanical automation degree is high; Improve operating efficiency greatly, reduced working strength of workers.
Grind outside crushing mechanism, gear mesh roller structure and the sizing screening mechanism and be provided with a sealed preventing dust blimp, and absorb dust, avoid when carrying out sorting, causing the molding sand dust to flash, avoid environmental pollution, guaranteed personnel's health by the dust absorption plant.
Be provided with guide post between two gears of gear mesh roller structure and the tooth rest, this guide post and tooth rest are slidingly matched, and the spring of gear being pressed to another gear is installed on the guide post.When the molding sand piece of bulk got between two gears, two gears were opened and are held the entering of molding sand piece and guarantee certain thrust, and spring is made a concession when pressure is excessive simultaneously, can play a protective role.The atresia conveyer belt also can be replaced by the grooved guide plate that tilts, and can further reduce manufacturing cost.
