Embodiment 1

[0019] Embodiment 1: with reference to attached Figure 1-8. A machine-made sand wind-force winnowing system, including a PLC controller, the discharge port of the mixed product lifter 01 is directly connected to the inlet of the buffer bin 02, the discharge port of the buffer bin 02 is directly connected to the inlet of the feeder 03, and the feeder 03 The outlet is connected with the feed inlet of machine-made sand air separator cabin 06, and the multi-stage outlets of machine-made sand air separator cabin 06 are respectively connected with the inlets of respective grading storage tanks 09 through feeding pipes, and the outlet of the main fan 010 is The tuyere is communicated with the main tuyere 21 in the machine-made sand wind-force wind separator cabin body 06, the air outlet of the auxiliary blower fan 04 is communicated with the auxiliary wind outlet 22 in the machine-made sand wind-force winnower cabin body 06, and The dust removal port 6 communicates with the dust co...

Embodiment 2

[0021] Embodiment 2: on the basis of embodiment 1, with reference to appended Figure 9 . A method for wind-force wind separation of machine-made sand, starting the main blower 010 and the auxiliary blower 04, the machine-made sand is lifted to the upper part of the mixed finished product lifter 01 through the hopper in the mixed finished product lifter 01 and passed through the mixed finished product lifter 01 The feed port enters the buffer bin 02, and the buffer bin 02 transports the machine-made sand in the bin to the feeder 03, and the feeder 03 evenly sends the machine-made sand into the first section of strong wind of the air separator cabin 06 The feed port of the compartment:

[0022] The machine-made sand located in the feeding chamber of the first section of strong wind cabin adjusts the size of the wind power of the main fan 010 and the size of the wind power of the auxiliary fan 04 according to the size and weight of the selected particle size. Under the action,...

Embodiment 3

[0025] 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 winnowing method, which not only can adopt wind power to realize selection of machine-made sand with different particle sizes, but also realizes dustlessness. The machine-made sand wind power winnowing system comprises a PLC (Programmable Logic Controller), wherein a discharge opening of a mixing finished product bucket elevator directly faces to the inlet of a buffer stock bin; a discharge opening of a buffer stock bin directly faces to the inlet of a feeding machine; the outlet of the feeding machine is communicated with a feed opening of a machine-made sand wind power air separator cabin; multiple stage discharge openings of the machine-made sand wind power air separator cabin are communicated with respective material storage cylinders in each stage through material conveying tubes; the air outlet of a main air blower is communicated with a main wind opening of the machine-made sand wind power air separator cabin; the air outlet of an assistant blower is communicated with assistant wind openings in the machine-made sand wind power air separator cabin; a dedusting opening in the machine-made sand wind power air separator cabin is communicated with the inlet of a dust remover.

Description

technical field [0001] The invention relates to a machine-made sand air-selection system and air-selection method which can realize the selection of machine-made sand with different particle sizes and dust-free machine-made sand by using wind force, and belongs to the field of machine-made sand air-separation system manufacturing. Background technique [0002] CN101795774A, the title "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 device and the negative pressure recovery mechani...
