step 2) when the dust accumulation in the dust remover (4) reaches the full storage capacity, the dust removing side loading level gauge (5) sends a high-level signal to the automatic control system (12), the automatic control system (12) opens an exhaust valve (82) on the bin pump, then opens a feed valve (81) to start feeding, then the ash feeding screw machine (6) is started in full load, the ash feeding screw machine (6) starts to work until the bin pump is full, the ash feeding screw machine (6) stops, and finally the feed valve (81) on the bin pump is closed;
step 3), atomizing dust in the bin pump by an air compressor matched with the bin pump through an air storage tank and an air circuit, and then conveying the atomized dust into a dust storage tank (11) through a dust conveying pipeline (9);
and 4) realizing the automatic circulation of the steps 1) to 3) through an automatic control system (12) until the dust storage tank (11) reaches the full position, and finally adopting a conveying device to convey the full-position dust storage tank (11) outwards.
2. The method of sand processing and dust removal of claim 1, further comprising: the number of the dust collectors (4), the bin pumps and the dust storage tanks (11) is multiple, the dust collectors (4) and the bin pumps are connected in parallel and in series, and finally, dust is input into one or more dust storage tanks (11).
3. The method of sand processing and dust removal of claim 1, further comprising: the tank body side loading level indicators (10) are at least 3 in number and are respectively connected with the high position, the middle position and the low position of the tank body of the dust storage tank (11).
4. A method of sand processing and dust removal as claimed in claim 3, wherein: the volume of the bin pump is smaller than that of the cone of the dust remover (4).
