When used sodium silicate sand and water after advance sand hopper 5 and add stavings 1, open valve 26, the chemicals that helps water-glass sand regeneration as everyone knows that is stored in advance in the explosive barrel 6 is added in the staving 1 by drug-feeding tube 27, reducing motor 7 impeller 13 rotations simultaneously, sand grains in the water, sand group are stirred, make between sand grains and the sand grains, between sand grains and the impeller, produce strong friction between sand grains and the bucket wall.Heat supply nozzle 14 ejection high velocity vapor heat sand and water simultaneously in this process, can be heated to boiling point always.Along with the rising of water temperature, the solubility of silica gel in water increases greatly, and the adding of chemicals can impel that sodium oxide molybdena obtains removing more completely in the old sand.Under the acting in conjunction of above-mentioned factor, the waterglass inert coating on old sand surface comes off rapidly, dissolves.When reclaimed sand reaches requirement, can suspend impeller 13 rotations and nozzle 14 spray vapour and close blowoff valve and the sand inlet flashboard 4 of closing blow-off pipe (25), open the blowoff valve of base plate 19 bottoms, in staving 1, feed compressed air through air inlet pipe 10, residue sewage is extruded outside the staving by the sand block steel wire 23 on the base plate 19, porous disc 21, sewage pipe 22 successively as far as possible.Close the valve on the blow-off pipe 22 at last, open sand inlet flashboard 4, add water the reclaimed sand in the staving is cleaned.All over cleaning, reclaimed sand can be opened sand export base plate 19 after reaching requirement, emits reclaimed sand through several.
Fig. 4 is the cutaway view of another embodiment of regenerating device 1, and present embodiment and Fig. 1 difference are that staving 1 is horizontal setting, and heater is that tubular electrothermal element 14 administration devices are located at the into top of sand hopper 5.
Sometimes be mixed with not molten fully little sand group, antiquated sand piece and other foreign matter of opening in the reclaimed sand of from regenerating device 1, discharging,, can send into this reclaimed sand in the regenerating device 2 and be for further processing in order to obtain high-quality reclaimed sand.
The casing 1 that Fig. 5 shows regenerating device 2 is horizontal type device, and support roller 2 is fixed on the top of casing 1, and cylinder 3 is placed in the top of support roller 2 and the part of cylinder cylindrical is immersed in the water in the casing 1.The cylindrical wall of cylinder 3 is provided with many sand apertures, and the inboard of wall is provided with helical blade, and an end of cylinder also is provided with belt pulley 4.Top cover 6 covers cylinder 3 and is fixed together with casing 1.Reductor 9, motor 10 are installed in the top of casing 1.Adopt profile of tooth adhesive tape 7 or V-Belt Drive between reductor 9 and the cylinder 3.Motor 10 can drive cylinder 3 by reductor 9 and rotate on support roller 2.The two ends of cylinder 3 are respectively equipped with into sand hopper 5 and deslagging bucket 20.Contain explosive barrel 8, valve 21 and drug-feeding tube 23 and connect the composition administration device successively, valve 21 can be controlled dispensing.Administration device is fixed on the top of casing 1 by drug-feeding tube 23.
The bottom of casing 1 is provided with 3 heat supply nozzles 14, and nozzle interior is provided with porous disc and steel wire.Nozzle 14 is connected by steel pipe 18 and steam boiler (not drawing among the figure).Be provided with purge chamber 16 and sediment outflow groove 17 at casing 1 away from that end end of cylinder, be provided with the permeable dividing plate 22 of sand block in the purge chamber 16.Impeller 13 is fixed on the axle of reducing motor 12 and goes up composition impeller sand removing device.The impeller sand removing device is fixed on the roof between purge chamber and the sediment outflow groove, and makes impeller 13 be in the position that can dial in the reclaimed sand on 16 tops, purge chamber sediment outflow groove 17.The bottom of casing 1 also is provided with helix transporting device 11, and this device can be transported to reclaimed sand the purge chamber 16 in casing 1.
After used sodium silicate sand is in advancing sand hopper 5 adding cylinders 3, opening valve 21 adds in the casing 1 being stored in the chemicals of containing in the explosive barrel 8 that helps water-glass sand regeneration in advance, heat supply nozzle 14 ejection high velocity vapor heat the Sha Heshui in the casing 1 simultaneously in this process, can be heated to boiling point.Motor 10 drives cylinder 3 by reductor 9 and rotates on support roller 2, and the part of cylinder 3 is under water.Enter old sand in the cylinder under the effect of cylinder, bleed in the casing less than the sand grains of cylinder wall bore dia or sand group, under the effect of helical blade, the continuous fragmentation of quilt of advancing is on one side bled in the casing 1 greater than the sand group of cinclides diameter.The indissoluble agglomerate that last end is broken and other foreign matter arrive deslagging bucket 20 and are discharged from regenerating device.Bleed sand grains in the casing 1 or sand group under cylinder 3 constantly stirs; fully washing adds the effect of chemicals in hot water, and the waterglass film of sand grain surface comes off rapidly, dissolves; reclaimed sand sinks to the bottom of casing 1, is clamp-oned in the purge chamber 16 by helix transporting device 11.Reclaimed sand further is subjected to strong rubbing cleaning in this process, and indivedual remaining little sand are rolled into a ball to be rubbed with the hands and opened.Reclaimed sand constantly rises in purge chamber 16, and reducing motor 12 drives hour wheels 13 rotations, the reclaimed sand that rises from the water surface is dialled in sediment outflow groove 17 and discharges outside the regenerating device.
In above-mentioned regenerative process, clear water flows in the purge chamber 16 from water inlet pipe 19 earlier, flows in the casing 1 through water pipe 15 behind the cleaning and regeneration sand again.Sewage in the casing 1 flows out through blow-off pipe 24.Shutting down the sewage and the reclaimed sand that retain in the regenerating device of back can discharge by blow-off pipe 25.
During the supporting use of regenerating device 2 and regenerating device 1, can not establish administration device.
Fig. 7 is another embodiment sketch of regenerating device 2.With Fig. 5 difference be that the heater of casing 1 bottom is a tubular electrothermal element 14, sand removing device is directly the reclaimed sand in the casing 1 to be discharged outside the regenerating device with a helix transporting device 11.Conveying worm 11 lower cases are provided with some sand block permeable holes, and present embodiment is not provided with administration device in addition.
When the reclaimed sand quality requirement was not tight, available regenerating device 2 was produced reclaimed sand, otherwise should combine production reclaimed sand to regenerating device 1 and regenerating device 2.This moment is for simplified apparatus, on the regenerating device 2 even can also not establish heater.
The above only is a preferred embodiment of the present invention; under the prerequisite that does not break away from the principle of the invention; also can do some modification and improvement; as unit being changed into the two-shipper parallel connection; the heater of small-sized regenerating device is changed into direct flame heat staving or the casing etc. used, all should be considered as belonging to the protection domain of patent of the present invention.
