Abstract
The invention discloses a technological process of a Lost-wax casting waste shell total regeneration utilization new process. The new technological process of the invention comprises the following steps: waste shell collection -roll-polishing and impurity removal-de-ironing by magnetic force -refining and crushing-laying screening - measurement and package, the technological process produces regeneration sand particles by adopting a mechanical matching coordinated process. The invention is energy-saving and environment-protective, thereby bringing good overall economic efficiency.
Description
Technical field
The present invention relates to a kind of twice laid and preparation method, be particularly useful for the whole regeneration new technologies of lost-wax casting waste shell of casting sand, shell.
Background technology
During lost-wax casting universal machine accessory product, steel-casting per ton has the waste shell of 350 kilogram weights approximately.These housings are by silica flour, quartz sand, do not come powder, do not come sand to form integral body through binding agent, and through the roasting moulding, behind the casting product, routine is to clean out the workshop, and the wilderness is abandoned in haul, also wants pay the freight.The raw material of this shell all are that natural crystal is made through pulverizing, about 500 yuan per ton, and the ore deposit storage is fewer and feweri, causes the cast steel cost higher.
Summary of the invention
The purpose of this invention is to provide the whole regeneration new technologies of a kind of lost-wax casting waste shell, this method mechanization degree height, labour intensity is low, energy consumption is little, environmental protection is good.
The objective of the invention is to realize that with following technical scheme described new technological flow is: useless shell collection → roll cast removal of impurities → magnetic force de-iron → refinement fragmentation → hierarchical screening → metering packing.Wherein roll cast dedusting station cylinder is a hexagon, and periphery is a plurality of rectangle notches, and the block of being convenient to certain specification is dished out from notch and fallen on the conveyer belt; Magnetic force de-iron station is to embed magnetic block on the iron roller, utilizes magnetic force to absorb bloom, steel grit on the motion conveyer belt; The broken station of refinement is pulverized output by pulverizer; The hierarchical screening station is selected the sand particle and the powder of different size by the vibratory sieve of the different mesh sizes that tilt.
It is 95 yuan per ton that whole recovery prepares reclaimed sand explained hereafter cost, and nearly 500 yuan of recycling replacement fresh sands re-use value and are about 400 yuan per ton.Make cast steel enterprise reduce production costs, increase the good approach that benefit is fully developed talents.
The specific embodiment
The whole regeneration new technologies of the smart casting waste shell of a kind of paraffin, the shell that at first will give up is collected, utilize polygon cylinder roll cast housing that the broken solid of housing is fallen on conveyer belt by notch on the tube face then, foreign material removal suitable for reading, remove iron block through the magnetic roller, and then after conveyer belt input pulverizer is pulverized, import the layered vibration sieve again, obtain the sand grains of different size, the metering packing of classifying again at last.The whole recovery preparation process can be saved great amount of cost, can create bigger profit margin for enterprise.
Claims (5)
