On the contrary, the embodiments of the disclosure include all alternatives, modifications, and equivalents as may be included within the spirit and scope of the appended claims.

As shown in fig. 1 and 3, the embodiment of the disclosure provides a dust removing pipeline, which comprises a separating box 1, a baffle 2 and a discharging box 3, wherein a passing channel 104 is formed between a first end 101 of the separating box 1 and a second end 102 of the separating box 1, a third end 103 of the separating box 1 is located below the passing channel 104, the third end 103 of the separating box 1 is communicated with the passing channel 104, the baffle 2 is movably arranged in the passing channel 104, the baffle 2 is used for adjusting the channel size of the passing channel 104, and a feeding end of the discharging box 3 is connected with the third end 103 of the separating box 1.

It can be appreciated that when the air with dust passes through the passing channel 104, the baffle 2 is movably arranged in the passing channel 104, so that the channel size of the passing channel 104 can be adjusted by adjusting the space position of the baffle 2 in the passing channel 104, thereby adjusting the flow rate of the air in the passing channel 104, and when the flow rate of the air is reduced, the light sundries with larger volume in the dust can be settled into the blanking box 3, thereby avoiding the blockage, damage and the like of the dust removing equipment caused by the light sundries with larger volume entering into the dust removing equipment, effectively improving the dust removing efficiency of the dust removing equipment and reducing the dust removing cost of the dust removing equipment.

It should be noted that, when the dust removing pipeline is installed in the dust removing device, the dust removing pipeline should be located between the dust removing device and the dust removing facility, so as to avoid light sundries with larger volume from entering the dust removing device. The dust-removing facility may be crushing equipment, screening equipment, belt conveyor, etc. for machine-made sand preparation, which is not limited.

The separation box 1 includes first end 101, second end 102 and third end 103, and the first end 101 of separation box 1 can be used for connecting by dust collecting facility, and the second end 102 of separation box 1 can be used for connecting dust collecting equipment, wherein, because the third end 103 of separation box 1 is located the below of passing material passageway 104, and the third end 103 of separation box 1 communicates with passing material passageway 104 for when the air velocity of flow in passing material passageway 104 reduces, the light debris of great volume can utilize self gravity to subside in the third end 103 of separation box 1, and then enters into the unloading case 3.

The size of the passage of the passing channel 104 may be the diameter of the passing channel 104 or the cross-sectional area of the passing channel 104, which is not limited, wherein the size of the passage of the passing channel 104 is inversely proportional to the air velocity in the passage, i.e. the larger the size of the passage of the passing channel 104, the smaller the air velocity in the passing channel 104, and conversely, the larger the size of the passage of the passing channel 104, the smaller the air velocity in the passing channel 104.

When the space position of the baffle plate 2 in the passing channel 104 is adjusted, the air flow rate in the passing channel 104 is ensured not to be too large, so that light sundries with larger volume are prevented from entering the dust removing equipment, and meanwhile, dust and light sundries with larger volume are prevented from being settled into the blanking box 3 together. The specific spatial position of the baffle 2 in the passing channel 104 may be set according to actual needs, which is not limited.

The light sundries with larger volume can be plastic bags, plastic bottles, plastic barrels, wood chips, scrap iron and the like, and the light sundries are not limited.
