Description of reference numerals: 1-frame, 2-cylinder, 3-hopper, 4-Electric Appliance Cabinet, 5-lautertuns, 6-vibrating motor, 7-upper screen cloth, 8-vibration rack, 9-lower screen cloth, 10-worm gear reducer, 11-rotating shaft, 12-roller, 13-rotary shaft rack, 14-dust suction whirlwind tube, 14-1-dust catcher flange-interface, 14-2-sand-falling port.
The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
Shown in Fig. 1 ~ 2, the present invention includes frame 1, cylinder 2, hopper 3, Electric Appliance Cabinet 4, lautertuns 5, vibrating motor 6, upper screen cloth 7, vibration rack 8, lower screen cloth 9, worm gear reducer 10, rotating shaft 11, roller 12, rotary shaft rack 13 and dust suction whirlwind tube 14.
Said frame 1 upper end is vibration rack 8 fixedly, rotates mounting cylinder 2 on the vibration rack 8, and cylinder 2 inner surfaces are provided with a plurality of hoppers 3.Said hopper 3 has only an end opening.
The both sides of said cylinder 2 are respectively equipped with 12, two rollers 12 of two rollers and are fixed in the rotating shaft 11.Said rotating shaft 11 is installed on two rotary shaft racks 13 through bearing, and rotating shaft 11 1 ends connect worm gear reducer 10, and rotating shaft 11 is driven by worm gear reducer 10 and rotates.Said roller 12 adopts polyamine fat material, long service life.
Said cylinder 2 inside are provided with upper screen cloth 7 and lower screen cloth 9, and upper screen cloth 7 is fixed on the upper end of vibration rack 8, and lower screen cloth 9 is fixed on the lower end of vibration rack 8.Said upper screen cloth 7 lower ends are provided with lautertuns 5.Fixing vibrating motor 6 on the said vibration rack 8.Said upper screen cloth 7 is provided with a plurality of sieve screen apertures with lower screen cloth 9, and upper screen cloth 7 is used for the bulky grain of sand and Impurity removal, when lower screen cloth 9 filters the wax-pattern of being stained with behind the slurry and in cylinder, drenches sand and the lumps that falls.
Said vibration rack 8 one ends connect dust suction whirlwind tube 14, and dust suction whirlwind tube 14 is used for the sand dust that waves is sucked.Be provided with pipe in the dust suction in the said dust suction whirlwind tube 14, the wind sand of suction prevents that around pipe rotation in the dust suction suction of dust suction whirlwind tube 14 is excessive, and desired sand is all sucked.The upper end of dust suction whirlwind tube 14 is provided with dust catcher flange-interface 14-1, is used to connect dust catcher.Dust suction whirlwind tube 14 lower ends are provided with sand-falling port 14-2, and the sand dust that waves sucks dust suction whirlwind tube 14 backs through sand-falling port 14-2 knockout.
Fixing Electric Appliance Cabinet 4 on the said frame is provided with frequency converter in the Electric Appliance Cabinet 4, the rotating speed of Frequency Converter Control worm gear reducer 10.
Operation principle of the present invention is: before work, sand is poured in the cylinder 2.Start power supply, the frequency converter in the Electric Appliance Cabinet 4 is configured, worm gear reducer 10 drives roller 12 and rotates, and roller 12 frictions drive cylinder 2 and begin to turn clockwise.Hopper 3 openings in the cylinder 2 rotate to knockout after the eminence after sand is grabbed in the bottom.The vibrating motor 6 that is installed on the vibration rack 8 drives upper screen cloth 7 and lower screen cloth 9 vibrations, and during knockout process upper screen cloth 7, bulky grain in the sand and foreign material stay on the upper screen cloth 7, and through outside the discharge cylinders 2 in the vibration inflow lautertuns 5.Filter qualified sand and filters once more through lower screen cloth 9, lower screen cloth 9 mainly is that filtration is when being stained with wax-pattern behind the slurry and in cylinder, drenching sand and the lumps that falls.After sand after the filtration falls into cylinder 2 bottoms, because of cylinder 2 rotation, picked up by hopper 3 again and be promoted to eminence again and fall, so circulation is drenched sand and is filtered.
The present invention adopts the rotation of cylinder hopper to promote sand, omits tradition and drenches sand machine belt bucket type transport, and simple in structure, cost is low.Electric vibrating sieve sand, it is even to drench sand, and it is big to cross the sand area, can effectively separate lumps and foreign material.
