Air channel I25 and air channel II27 tilt to penetrate separation chamber's shell 13 from bottom to top, the axis of air channel I25 and air channel II27 and horizontal angle are 35 °, the plate V19 that gathers materials is 95 ° with the angle of plate VI20 of gathering materials, the plate III17 that gathers materials is 80 ° with the angle of plate IV18 of gathering materials, and the angle of gather materials plate I15 and the plate II16 that gathers materials is 130 °; Demarcation strip I21, demarcation strip II22, demarcation strip III23, demarcation strip IV24 and horizontal angle are 135 °; I25 outlet in air channel is apart from feed hopper 12 outlet 150mm, and II27 outlet in air channel is apart from the plate V19 and the plate VI20 crack 150mm that gathers materials of gathering materials;
The gather materials upper end of plate I15 is positioned at the lower edge of air outlet 14;
Blower fan I26, blower fan II28 are centrifugal blower, and power is 0.5-1.5 kilowatt;
Air channel I25, air channel II27 are made by galvanized iron sheet, and air outlet is a rectangular cross section, is of a size of 2000 * 50mm;
Separation chamber's shell 13 is the thick general steel plate rectangular box of 4mm, is of a size of 2000 * 2000 * 2000mm;
Feed hopper 12 is the bar shaped bucket, is of a size of 2000 * 50mm; Coarse sand discharging opening II29, fine sand discharging opening II30 are bar hole, are of a size of 2000 * 50mm;
Gather materials plate I15, the plate II16 that gathers materials, the plate III17 that gathers materials, the plate IV18 that gathers materials, the plate V19 that gathers materials, the plate VI20 that gathers materials, demarcation strip I21, demarcation strip II22, demarcation strip III23, demarcation strip IV24 is the thick rectangular steel plates of 4mm, the plate two ends are connected with separation chamber 13 liang of side box bodies of shell, and the plate I15 that gathers materials is of a size of 2000 * 600mm; The plate II16 that gathers materials is of a size of 2000 * 350mm with the plate III17 that gathers materials; The plate IV18 that gathers materials is of a size of 2000 * 600mm; The plate V19 that gathers materials is of a size of 2000 * 550mm; The plate VI20 that gathers materials is of a size of 2000 * 300mm; Demarcation strip I21, demarcation strip II22, demarcation strip III23, demarcation strip IV24 are of a size of 2000 * 300mm;
Feed hopper 12 is positioned at top, selection by winnowing chamber, sand to be selected is after feed hopper 12 flows out, under the wind-force effect that blower fan I26 provides, scatter out, big than fine particle scattering distance, enter the fines collecting region by demarcation strip III23, demarcation strip IV24, than the hopper that big particle enters the plate V19 that gathers materials, the plate VI20 that gathers materials forms.Under the wind-force effect that blower fan II28 provides, what flow out from the hopper that the plate V19 that gathers materials, the plate VI20 that gathers materials form is further disperseed than coarse sand granule, wherein than fine particle by demarcation strip I21, demarcation strip II22 enter the plate I15 that gathers materials, the plate II16 that gathers materials forms hopper fines collecting region and enter fine sand discharging opening II30, under the effect of the plate III17 that gathers materials, the plate IV18 that gathers materials, enter coarse fodder discharging opening 29 than big particle.
This centrifugal sand grains separator be mainly used in greater than with separate less than the sand grains of a certain control particle diameter, make it to satisfy the engineering application requirements.Its sand material disposal ability to be selected depends on the power and the rotating speed of used motor, and power of motor is big more, and rotating speed is high more, and output is just big more.When power of motor more than 10 kilowatts, hour handling capacity is greater than 30 tons, separative efficiency is more than 80%.
This split type sand machine automaticity height that selects is time saving and energy saving, simple in structure, durable in use, be easy to repair, treating capacity is big, meticulous sorting can sub-elect particle diameter greater than 0.6mm, 0.6-0.3mm, 0.3-0.15mm with less than the sand of 0.15mm, and the efficiency of separation can reach more than 70%.
