The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a kind of New Regenerated sand mechanical device described in the utility model, comprise magnetic separation conveyer belt apparatus 1, disintegrating machine 2, the first bucket elevator 3, regenerating device 4, the second bucket elevator 5, buffer bin 6, the 3rd bucket elevator 7, roaster 8, boiling cooling bed 9, the 4th bucket elevator 10, finished product bin 11 and subhead vibrating screen device 12, described disintegrating machine 2 one ends are connected with magnetic separation conveyer belt apparatus 1, and these disintegrating machine 2 other ends are connected with the first bucket elevator 3 one ends; Described first bucket elevator 3 other ends are connected with regenerating device 4 one ends; Described regenerating device 4 other ends are connected with the second bucket elevator 5 one ends; Described second bucket elevator 5 other ends are connected with buffer bin 6 one ends; Described buffer bin 6 other ends are connected with the 3rd bucket elevator 7 one ends; Described the 3rd bucket elevator 7 other ends are connected with roaster 8 one ends; Described roaster 8 other ends are connected with boiling cooling bed 9 one ends; Described boiling cooling bed 9 other ends are connected with the 4th bucket elevator 10 1 ends; Described the 4th bucket elevator 10 other ends are connected with finished product bin 11 1 ends; Described finished product bin 11 other ends are connected with subhead vibrating screen device 12.

The utility model in use, bulk antiquated sand in cast used sand is carried out fragmentation by magnetic separation conveyer belt apparatus 1 to disintegrating machine 2, after broken, antiquated sand is by the effect of the first bucket elevator 3, enter into 4 li of regenerating devices, spinning mill in 4 li of regenerating devices use it grinds the rubbing particle shape of having removed on sand grains residue and rounding, the granularity major part of the bentonite in antiquated sand and coal dust is less than 270 orders at this moment, these bentonites and coal dust can be regarded as the mud part in molding sand at this moment, and the dust of generation can use deduster to take away.And then antiquated sand is after treatment passed through the second bucket elevator 5, be sent in buffer bin 6, carry out scrub water in buffer bin 6, further remove bentonite and coal dust, this wants can be avoided carrying out in roaster 8 can producing the ceramic phenomenon after the bentonite roasting in thermal reclamation technique; Again with antiquated sand from 6 li of buffer bins, utilize the 3rd bucket elevator 7 to deliver to 8 li of roasters, to carry out thermal reclamation after wet antiquated sand dehumidifying pre-heating drying, mainly by high-temperature roasting, resin molding in antiquated sand burnt and removed the crystallization water in antiquated sand, reaching the effect that reduces the antiquated sand expansion rate and lower the antiquated sand gas forming amount; Antiquated sand is delivered to 9 pairs of antiquated sands of boiling cooling bed again lower the temperature, and utilize the waste heat after roasting that damp sand is further dried; This moment, antiquated sand was treated as useful type through multistep, molding sand after processing is again delivered to finished product bin 11 by the 4th bucket elevator 10, utilize subhead vibrating screen device 12 further to screen out bulky grain and micro mist in sand in 11 li treated molding sand of finished product bin, regenerated foundry sand after now processing according to client's requirement is divided into the sand of designated size, is packaged into bag.
