Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
As shown in Figure 1, a kind of vibrating dust removing technique, involving vibrations part and dust removal part, wherein oscillating component main body is screen box 11, the variant-frequency vibration motor 17 that described screen box 11 comprises charging aperture 12, discharging opening 13, sieve upper outlet 16, screen cloth 14 and is connected with screen cloth 14, described dust removal part comprises main exhaust 21, a blast pipe 22, air exhauster 23, motor 27 and dust collection 27, described screen cloth 14 is at least two-layer, and upper strata screen cloth 14 aperture is greater than lower screen 14 aperture, described charging aperture 12 is positioned at casing 11 side above ground floor screen cloth 14, described sieve upper outlet 16 is positioned at screen cloth 14 and casing 11 junction of charging aperture 12 offside, described discharging opening 13 is positioned at below lower screen 14, the stock guide 15 of an inclination is provided with between two-layer screen cloth 14, described stock guide 15 is positioned at one end of nearly sieve upper outlet 16 upper, described screen cloth 14 is all connected with variant-frequency vibration motor 15 with stock guide 15, nearly sieve upper outlet 16 side, a dust concentration test chamber 19 is provided with between screen cloth 14 and stock guide 15, a dust concentration photoelectric sensor is provided with in described dust concentration test chamber 19, described dust concentration photoelectric sensor is all connected with controller with the variant-frequency vibration motor 17 of screen cloth on the upside of it 14.
Described main exhaust 21 one end is connected with screen box 11 top, the other end is connected with air exhauster 25, described each height props up blast pipe 23 one end and connects sieve upper outlet 16 and discharging opening 13, the other end connects a blast pipe 22, the other end propping up gas comb 22 connects air exhauster 25, and described main exhaust 21 is provided with volume damper 24 with a blast pipe 22.
During work, dust enters screen box 11 from charging aperture 12, when screen cloth 14 vibrates, while dust radius being less than sieve aperture falls on the stock guide 15 under screen cloth 14, while particle large for radius is pushed away forward, if charging rate is too fast, when the dust that particle diameter is little is more, when dust arrives dust concentration test chamber 19, the dust concentration fallen may exceed threshold value, namely dust arrives when sieving upper outlet 16 still containing the dust being less than mesh size, sensor of dust concentration feeds back to controller, controller improves variant-frequency vibration motor 17 rotating speed, and then improve the vibration frequency of screen cloth 14, thus reduce the concentration that dust arrives dust concentration test chamber 19, the all dust sizes making arrival sieve upper outlet 16 are all greater than the aperture of place screen cloth 14, if the dust concentration fallen is lower than certain threshold value, then reduce variable-frequency motor rotating speed by controller, and then reduce the vibration frequency of screen cloth 14, reduce power consumption, on the other hand, drop into the dust on stock guide 15, finally drop in charging aperture 12 side the screening that lower screen 14 carries out a new round, for dust removal part, air force can be controlled according to airborne dust situation adjustment volume damper 24.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
