Abstract
The invention discloses a magnetic sorting machine for molding sand, which belongs to the field of casting machines. The sorting machine comprises a sand blasting device and a magnetic sorting roller which is used for magnetically sorting materials which are screened by a screening device, wherein the magnetic sorting roller is provided with an independent driving device respectively; a metal baffle plate is arranged between the screening device and the magnetic sorting roller and is provided with a discharging hole corresponding to the magnetic sorting roller; and a discharging device is arranged below the magnetic sorting roller. The magnetic sorting machine for the molding sand is used for casting iron in waste sand in a magnetic sorting mode and has high efficiency. Due to the design of pneumatic sand feeding and the metal baffle plate, the problem of agglomeration of the waste sand can be solved, and the iron in the waste sand can be extracted to the maximum extent.
Description
Technical field
The present invention relates to the foundry sand magnetic separator, it belongs to the foundry machinery field.
Background technology
Be used for preparing a kind of graininess refractory material of molding sand and core sand in the Foundry Production.Under with the situation of clay as moulding sand binder, 1 ton of qualified foundry goods of every production approximately needs to replenish 1 ton of fresh sand, and therefore the consumption of casting model powder is maximum in sand casting is produced.Can produce a large amount of antiquated sands in the Foundry Production, and contain a certain amount of iron in the antiquated sand, directly discharging causes great waste.At present, whether the proper recycled mode is arranged, more do not have the screening installation of special foundry sand, and common ore dressing magnetic separator and winnowing machine are very low for the efficiency of separation of foundry sand, and inapplicable.
Summary of the invention
Defective in view of prior art exists the object of the present invention is to provide a kind of foundry sand magnetic separator, solves the sorting problem of foundry sand, the irony composition in the casting model powder can be screened, and recycles.
For realizing above-mentioned purpose; The technical scheme that the present invention adopted is: the foundry sand magnetic separator; Comprise sand blasting unit and the magnetic separation roller that is used for the material after the screening plant screening is carried out magnetic separation; Said magnetic separation roller is respectively equipped with independently drive unit; Be provided with metal baffle between said screening plant and the said magnetic separation roller; Said metal baffle has the discharging opening corresponding with magnetic separation roller, and the below of said magnetic separation roller is provided with drawing mechanism.Said sand blasting unit comprises storage sand device; Pneumatic sand device and the air compressor of sending; Antiquated sand in the storage sand device connects the pneumatic sand device that send through pipeline, the high pressure draught through air compressor drive pneumatic send the sand device with antiquated sand from nozzle ejection on metal baffle.The adjustable included angle of the metal baffle of said discharging opening top and the antiquated sand jet path of said nozzle is between 30 degree-90 degree.Said drawing mechanism is a tape conveyor belt.
After adopting such scheme, compared with prior art have following beneficial effect: the foundry sand magnetic separator adopts the irony in the magnetic separation sorting cast waste sand, and efficient is high.Design pneumatic sand and the metal baffle sent, can solve the antiquated sand agglomeration problems, can extract the irony in the antiquated sand to greatest extent.
