The utility model sorts out automatically by the impurity that photovoltaic principals will be mixed in the particle, be swift in motion, accurately, not only sort efficient and accuracy rate improves greatly, and saved lot of manpower and material resources, change the standard edition in the photoelectric detector, can apply to any solid particle industry that needs letter sorting impurity.

Be described further below in conjunction with drawings and Examples:

Description of drawings: figure is 1 device schematic diagram.

Fig. 2 is the photoelectric detector schematic diagram.

Fig. 3 passes through the detector schematic diagram for particle.

Fig. 4 is electronic control principle figure.

Fig. 5 is the power unit schematic diagram.

Funnel among Fig. 1 (1) is contained the particle that needs letter sorting, particle (2) is by the continuous whereabouts of simple grain in the funnel and by passing through in the photoelectric detector (3), if the signal of telecommunication of photoelectric detector changes, then electronic control part (4) control magnetic valve (6) action, gases at high pressure in the gas tank (5) are sprayed by nozzle (9), this moment, impurity was just in time fallen the nozzle place, gases at high pressure are about to impurity and blow in the non-standard container (8), if photoelectric detector does not have letter output, then be standard compliant particle, particle is directly fallen in the volumetric standard (7).

Fig. 2, Fig. 3 are the photoelectric detector schematic diagram, and the color of on-gauge plate (10) is identical with the color that needs letter sorting particle (2), luminous tube L ₁, L ₂With photo resistance R ₀On same straight line and relative with on-gauge plate, particle is by passing through between on-gauge plate and the photo resistance.Connect power supply, luminous tube L during work ₁L ₂Promptly luminous, its light that sends is incident to photo resistance R after the on-gauge plate reflection ₀Photo resistance has certain resistance under the irradiation of this intensity light, when particle drops between on-gauge plate and the photo resistance (showing) as Fig. 3, the light that luminous tube sends reflexes to photo resistance by particle, if the color of whereabouts particle is different with on-gauge plate or be other impurity, it is different with the light that reflects on the on-gauge plate then to reflex to the light of photo resistance from particle, the intensity that promptly incides the photo resistance glazed thread is with great changes will take place, the electronic control system then variation of the resistance of photo resistance at this moment converts the signal of telecommunication to, and control magnetic valve (6) and open, with gases at high pressure it is blown away.If the particle that falls is certified products, it is very little then to reflex to the intensity variation of photo resistance by particle, and less variation also only takes place the photo resistance value, no signal of telecommunication output, and then particle freely falls in the volumetric standard (7) of Sheng certified products.

Fig. 4, Fig. 5 are the electronic control circuit schematic diagram, mainly are made up of electronic control part and power unit, and the core of electronic control part is an ic chip ₁And IC ₂, ic chip ₁With adjustable resistance W ₁, photo resistance R ₀And capacitor C ₁Form audio frequency oscillator, its frequency of oscillation is decided by photo resistance and adjustable resistance W ₁Resistance, determine resistance W ₁Resistance, photo resistance 4R then ₀The variation of resistance will cause the variation of oscillator frequency of oscillation.Ic chip ₂With adjustable resistance W ₁And capacitor C ₄The component frequency decoder is by adjusting resistance W ₁, W ₂Its centre frequency of resistance can be identical with the frequency of oscillation of audio frequency oscillator, if the identical then IC of two frequencies ₂8 pin be output as low level, triode BG ends, not adhesive of relay J, magnetic valve (6) cuts out, as photo resistance P ₀Resistance change, when promptly the particle that passes through in the photoelectric detector was impurity, then the frequency of oscillation of audio frequency oscillator departed from IC ₂The centre frequency of the frequency decoder of forming is a lot, then IC ₂Be output as high level, by resistance W ₂, capacitor C ₂Time-delay makes triode BG conducting, thereby makes impurity just fall magnetic valve nozzle (9) when locating, and magnetic valve cuts out after opening impurity being blown away immediately.Adjust resistance W ₃Class value can adjust Time Delay Opening time of magnetic valve (6), can adjust resistance W according to photoelectric detector (3) to the distance between nozzle (9) thus ₃Resistance, make impurity open magnetic valve by photoelectric detector and when just falling the nozzle place.The power unit of electronic control circuit is by transformer 220V voltage to be become two groups of low tensions, and one group through bridge rectifier and ic chip ₃And capacitor C ₈～C ₁₁For electronic control part provides stable low-voltage, another is organized through bridge rectifier and ic chip ₄And capacitor C ₁₂～C ₁₅Be luminous tube L ₁, L ₃Stable low-voltage is provided.
