Problems solved by technology

[0002] The vibrating screen is a commonly used screening machine. It uses the principle of vibrating particles to sieve the particles out of the screen. The small particles fall on the screen, and the large particles are located above the screen and discharged from the other hole. The biggest problem of the vibrating screen is The noise is loud, and several vibrating screens are placed in the same workshop, and even the speech cannot be heard
[0003] 201610502208.2 discloses a plastic particle screening device, which proposes to rely on the principle of winnowing to sieve plastic particles, but put all plastic particles in a suspended state, and re-screen, the efficiency is low, the difficulty is large, and the practicability is not good. powerful

Embodiment 1

[0031] Such as figure 1 As shown, the screening machine described in this embodiment includes a winnowing device 1, an oblique screening device 2 and a tail screening device 3, and the winnowing device 1, the diagonal screening device 2 and the tail screening device 3 are connected in sequence.

[0032] Among them, such as figure 2 As shown, the winnowing device 1 comprises a casing 101, a support 102 and a feed hopper 103, the casing 101 is located above the support 102, the feed hopper 103 is positioned above the casing 101, and the casing 101 The top is provided with feeder 104, and described feeder 103 is positioned at the top of feeder 104, and the bottom of feeder 104 has a flat strip outlet; An air outlet 106 is arranged on the opposite side of the air outlet 105, a screen 107 is arranged inside the air outlet 106, and an air bag 108 is arranged outside the air outlet 106; The outlet hopper A110 and the outlet hopper B111 are respectively provided with the outlet hop...

Embodiment 2

[0040] Such as Figure 5 As shown, the screening machine described in this embodiment is different from Embodiment 1 in that: the top of the casing 101 is provided with an opening 113, the two sides of the feeder 104 are respectively provided with guide rod seats 114, and the feeder 104 Both ends are provided with guide rods 115 that can move in the guide rod base 114, and a motor A116 is fixed on the side of one of the guide rod bases 114, and the motor A116 is connected with a screw rod 117 in transmission, and the screw rod 117 passes through the corresponding guide rod base 114 is then screwed with a nut 118 connected to the feeder 104, and the guide rod seat 114 is provided with a bearing at the place where the screw rod 117 passes.

[0041] In the screening machine described in this embodiment, under the action of the motor A116 (preferably a stepper motor), the feeder 104 can move left and right, and the difference in the position of the feeder 104 will determine the si...

Embodiment 3

[0043] Such as Figure 6 , 7 As shown, the screening machine described in this embodiment is different from Embodiment 1 in that: the fan 105 is divided into an upper fan A119 and a lower fan B120, and an upper partition 121 is provided in the casing 101. The upper partition 121 is located between the upper fan A119 and the lower fan B120. The upper partition 121 is provided with a sub-hopper A122 on the left side and a sub-hopper B123 on the right side. The strips at the bottom of the sub-hopper A122 and the sub-hopper B123 are The outlets are located below the left side of the upper partition 121, and the outlet of the sub-hopper A122 is closer to the lower fan B120; the left refers to the direction closer to the fan 105;

[0044] The improvement of this embodiment is also suitable for the scheme of embodiment 2.

[0045] In the screening machine described in this embodiment, the large particles are equivalent to two air separations. The large particles are separated to th...

Abstract

The invention discloses a screening machine comprising a winnowing device, an oblique screening device and a tail screening device which are connected in turn. The screening machine disclosed by the invention has the beneficial effects that large particles and small particles can be separated with the winnowing device first, and further screening is performed through the oblique screening device and the tail screening device, so the screening machine has the advantages of winnowing; at the same time, the oblique screening device and the tail screening device adopt a rotary screening mode, so the noise is can be obviously reduced compared with the vibratory screening mode of the existing vibrating screen, and the practicality is high. The invention also designs a classification screening method for plastic particles which are classified into four classes A, B C and D from big to small. The classification screening method for plastic particles is characterized in that the screening machine disclosed by the invention is applied. The classification screening method has the features of convenience and low noise.

Description

technical field [0001] The invention relates to a classification and screening method for screening machinery and plastic particles. Background technique [0002] The vibrating screen is a commonly used screening machine. It uses the principle of vibrating particles to sieve the particles out of the screen. The small particles fall on the screen, and the large particles are located above the screen and discharged from the other opening. The biggest problem of the vibrating screen is The noise is so loud that several vibrating screens are placed in the same workshop, and even speech cannot be heard. [0003] 201610502208.2 discloses a plastic particle screening device, which proposes to rely on the principle of winnowing to sieve plastic particles, but put all plastic particles in a suspended state, and re-screen, the efficiency is low, the difficulty is large, and the practicability is not good powerful. Because of such problems, it is necessary to improve the existing scr...
