Embodiment 1

[0042] Embodiment 1: with reference to attached Picture 1-1 and 1-2 . A dust-free mechanism natural sand production and separation system, including a PLC controller, the stone passes through the stone conveying mechanism A1 to the feed port of the sand making machine A, and the discharge port of the sand making machine A is directly facing the starting end face of the machine-made sand conveying mechanism A2, and the mechanism The end of the sand conveying mechanism is directly facing the feed end of the modular multi-layer vibrating screen D, and the discharge end of the modular multi-layer vibrating screen D is directly facing the feed end of the mechanism natural sand machine matching adjustment system B, and the mechanism natural sand machine matching adjustment The discharge end of system B is directly facing the feed end of machine-made sand wind separation system C, and the discharge ports of machine-made sand with different particle sizes in machine-made sand wind se...

Embodiment 2

[0078] Example 2: On the basis of Example 1, a wind separation method for making natural sand with a dust-free mechanism, the stone passes through the stone conveying mechanism A1 to the feed port of the sand making machine A, and the sand making machine A makes the stone into a mechanism After the sand is discharged from the discharge port of the sand making machine A to the end face of the machine-made sand conveying mechanism A2, the end of the machine-made sand conveying mechanism A2 continuously drops the machine-made sand to the modular multi-layer vibrating screen D for screening, and the screened out The machine-made sand is transported to the machine-made natural sand machine with adjustment system B, and the machine-made natural sand machine is equipped with the adjustment system B to make the machine-made natural sand into the machine-made sand wind separation system, and the machine-made sand wind power wind separation system starts the main fan 010 and the auxiliary...

Embodiment 3

[0085] Embodiment 3: On the basis of Embodiment 2, the main tuyere located at the lower end of the feed port of the first strong wind cabin 2 is strongly supplied with wind under the action of the main fan 01, and the machine-made sand is fed by the feed chamber 23 of the first strong wind cabin. Blow into the adjacent first stage boiling chamber 24, because the two sides of the first stage boiling chamber 24 are provided with auxiliary air outlets 04 to supplement the air volume, so that the machine-made sand is continuously blown from bottom to top in the first stage boiling chamber. The wind blowing on both sides, during which the quality of the large-grained machine-made sand exceeds the blowing of the wind, so the machine-made sand of this level enters the first-stage grading storage tank 09 from the outlet 25 of the first-stage strong wind cabin, and the quality The machine-made sand that is less than the wind force is blown up through the boiling chamber into the first s...

Abstract

The invention relates to a machine-made sand wind power winnowing system and a machine-made sand wind power winnowing method capable of realizing the selection of machine-made sand of different grain sizes through wind power and capable of realizing the dust-free performance of the machine-made sand. The system comprises a programmable logic controller (PLC), wherein a discharging hole of a mixed finished product bucket elevator faces an inlet of a buffer bin; a discharging hole of the buffer bin faces an inlet of a feeder; an outlet of the feeder is communicated with a charging hole of a cabin body of a machine-made sand wind power winnower; a plurality of stages of discharging holes of the cabin body of the machine-made sand wind power winnower are communicated with inlets of self grading storage tanks through conveying pipes respectively; a wind outlet of a main fan is communicated with a main wind port in the cabin body of the machine-made sand wind power winnower; a wind outlet of an auxiliary fan is communicated with an auxiliary wind port in the cabin body of the machine-made sand wind power winnower; a dust removal port in the cabin body of the machine-made sand wind power winnower is communicated with an inlet of a dust remover.

Description

technical field [0001] The invention relates to a production and separation system and method for dust-free machine-made natural sand, which can not only realize the selection of machine-made sand with different particle sizes by using wind force, but also realize the dust-free machine-made sand selected, and belongs to the field of machine-made sand winnowing system manufacturing. Background technique [0002] CN101795774A, the name "sand making device, sand making method and sand making", at least includes a crusher for crushing crushed raw materials; the first sorting device, which uses wind power sorting of air supply and screening of sieves to separate The crushed material from the crusher is sorted into coarse particles, fine particles and fine powder; the negative pressure recovery mechanism, which attracts the fine powder in the first sorting device and recovers it, is characterized in that: in the first sorting A second sorting device is installed midway between the...
