Be described for the mixture fast separation device of capsule, softgel shell and medicinal powder below.
Refer to Fig. 1, a kind of mixture fast separation device, comprising: hopper 1, and described hopper 1 is for holding the mixture of capsule to be separated, softgel shell and medicinal powder; There is the first passage 10 of charging aperture 101 and discharging opening 102, described first passage 10 is communicated with described hopper 1 by described charging aperture 101, described discharging opening 102, in the horizontal direction lower than described charging aperture 101, can be discharged through described discharging opening 102 to make the material entered through described charging aperture 101 under the effect of himself gravity; There is the second channel 20 of first end and the second end, described second channel 20 is communicated with described first passage 10 by described first end, described first end is between described charging aperture 101 and described discharging opening 102, described second channel 20 entirety is positioned at the top of described first passage 10, and its longitudinally becomes predetermined angle with gravity direction; To be arranged in described second channel 20 and near the aspiration tube 30 of described first end, the airflow direction that described aspiration tube 30 bloats points to described second end; Described second end is provided with separate mesh 40 and outlet 60, and described outlet 60 is downward-sloping, and material can rebound through described separate mesh 40 and to discharge through described outlet 60.
For prior art when being separated capsule, softgel shell and medicinal powder mixture, the inefficiency of existence and be separated halfway deficiency, present embodiment provides a kind of mixture fast separation device.By blasting gas in second channel 20, make fast compared with first passage 10 two ends of the air velocity of first passage 10 and second channel 20 interconnecting part (i.e. the throat of first passage 10), from Venturi effect, small in ends compared with first passage 10 of the pressure of the throat of first passage 10, namely at the throat of first passage 10 and its two ends because the difference of air velocity creates pressure differential, under the effect of pressure differential, in mixture, different mutually separated of proportion comes, and more mechanical separate mode, the capsule that present embodiment obtains after being separated, softgel shell and medicinal powder can not damage.
The main thought that present embodiment is separated the mixture of capsule, softgel shell and medicinal powder utilizes Venturi effect, and the throat to Venturi tube advertises gas, due to the difference of air velocity, produces pressure reduction in the throat of the both ends of Venturi tube and Venturi tube; This pressure reduction is utilized different for proportion in mixture being separated to be come.The principle of Venturi effect is when air-flow blows over obstacle, relatively low at the back side near ports air pressure of obstacle, thus produces suction-operated and cause air current flow.Namely the principle of Venturi tube is by changing internal diameter of the pipeline, making air-flow from the coarse to fine, to accelerate gas flow rate, " vacuum " district is formed between Venturi tube is imported and exported, be somebody's turn to do " vacuum " district less than all lateral pressures, thus form pressure reduction, and then produce suction-operated.

Q∝S·v
Wherein: Q-flow;
S-area of section;
V-speed.
From flow conservation theorem, when air-flow is by trunnion 4 that sectional area is less, flow velocity v increases, and causes the static pressure at the some b place in trunnion 4 to be less than the static pressure at c point place in a point place in inlet tube 2 and outlet 3, thus forms pressure reduction, and then produce suction-operated.
Venturi effect is applied in present embodiment, namely be to second channel 20 by aspiration tube 30, then namely first passage 10 and second channel 20 connectivity part define the throat of first passage 10, described throat is little than the air pressure of charging aperture 101 and discharging opening 102, thus due to pressure reduction make described throat locate produce suction-operated.Through capsule, softgel shell and medicinal powder mixture that hopper 1 falls, under this suction-operated, the softgel shell that proportion is less and medicinal powder enter second channel 20 through described throat, the capsule that proportion is larger is then discharged through discharging opening 102 under the effect of self gravitation, completes the initial gross separation of capsule, softgel shell and medicinal powder.Initial gross separation is according in mixture, the separation that the difference of mixed phase proportion is carried out, and the less softgel shell of the capsule that namely proportion is larger and proportion is separated with medicinal powder.
