Further, also involving vibrations dispersal device, described vibrating device involving vibrations motor and oscillating plate, two shake motor symmetry be installed on oscillating plate on, oscillating plate is downward-sloping towards charging aperture direction, when the work of vibration dispersion device, the synchronous reversion of vibrating motor is to drive oscillating plate up-down vibration, horizontal movement.
From the above-mentioned description of this invention, the winnowing sand equipment of adjustable product modulus of fineness provided by the invention can be realized the further classification to Machine-made Sand, control the granularity that reclaims goods, solve current mechanism sand finished product grating inhomogeneous, the difficult problem that powder containing quantity is higher, in assorting room, air-supply arrangement is blown to dedusting mouth direction by multiple air inlets, by selection by winnowing repeatedly with obliquely upward to high wind, when having increased material and having fallen with time of contact of high wind, make classification more accurately, strengthen selection by winnowing effect; By regulating the angle of deep bead, striker plate, and the size of intake can be controlled the ratio of fines and coarse fodder and the modulus of fineness of product.
Brief description of the drawings
Fig. 1 is the structural representation of the winnowing sand equipment of adjustable product modulus of fineness of the present invention.
Fig. 2 is the enlarged drawing of M in Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, the invention will be further described.
Shown in Fig. 1, a kind of winnowing sand equipment of adjustable product modulus of fineness, comprises air separating bin 1, vibration dispersion device 2, air-supply arrangement 3, dust arrester 4, deep bead 5 and striker plate 6;
On air separating bin 1, establish by charging aperture 11, dedusting mouth 12, air inlet 13, equal air compartment 14, discharging opening 15, charging aperture 11 and dedusting mouth 12 are opened in respectively air separating bin 1 top and are arranged in the left and right sides at air separating bin 1 top,
All air compartment 14 is arranged at and between air inlet 11 and air-supply arrangement 3, makes the air-out speed on air separating bin 1 air inlet 11 widths and angular distribution is unified and by adjusting intake, blast and the high wind direction in the opening-closing size adjusting air separating bin 1 of equal air compartment 14;
