For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The utility model discloses a negative pressure separator for garbage screening, such as Figure 1 , 2 As shown, the negative pressure air separator for construction waste comprises a negative pressure fan 1, a dust collecting hood 7, a collecting hopper 4, a collecting hood 2, a material distribution barrel 8 and a recovery pipeline 3. The collecting hood 2 is cylindrical, with a certain height difference between the two ends. One end of the collecting hood 2, i.e., the top end when in use, is provided with a mounting port for installing the negative pressure fan 1, and the other end, i.e., the bottom end when in use, is provided with a feed port for installing the dust collecting hood 7. The material distribution barrel 8 is connected to the side wall of the collecting hood 2; the recovery pipeline 3 is connected between the material distribution barrel 8 and the collecting hopper 4.

[0027] When in use, the dust collecting hood 7 is covered on the material feeding roller or the material conveying line, and the negative pressure generated by the negative pressure fan 1 can absorb light garbage such as packaging bags into the dust collecting hood 7 and enter the material collecting hood 2; the negative pressure fan 1 forms a centrifugal cavity in the material collecting hood 2 to generate rotating wind force, and under the action of the rotating wind force, the light garbage in the material collecting hood 2 is driven to rotate, and during the rotation process, enters the material separation barrel 8, and then enters the material collecting hopper 4 through the recovery pipeline 3 to achieve sorting. With the above structure, only one fan is needed, and the power consumption is reduced by 50%.

[0028] The recovery pipeline 3 can be a hard pipe or a soft pipe, and a soft pipe is preferably used.

[0029] In order to improve the reliability of light garbage entering the material distribution barrel 8, the width of the end of the material distribution barrel 8 connected to the material receiving cover 2 is greater than the width of the end connected to the recovery pipeline 3. Figure 1 As shown, the cross section of the distribution barrel 8 is an isosceles trapezoid.

[0030] The material collecting cover 2 includes a top plate, a bottom plate and a side plate arranged between the top plate and the bottom plate, wherein the side plate includes an arc-shaped side plate and a guide side plate connected to the arc-shaped side plate, wherein the guide side plate is a flat plate. Preferably, the arc-shaped side plate is three-quarters of a circle, and the guide side plate is tangent to the arc-shaped side plate. Figure 1 As shown, the direction of the rotating wind force generated by the negative pressure fan 1 is counterclockwise. The light garbage rotates counterclockwise under the action of the rotating wind force. When it rotates to the guide side plate, it enters the distributing barrel 8 along the guide side plate under the guidance of the guide side plate.

[0031] The dust collecting hood 7 can adopt various shapes, such as a straight cylinder. In order to increase the area of ​​the negative pressure adsorption region, it is preferably in a trumpet shape.

[0032] For example, in order to improve the stability of the operation of the equipment, it also includes a mounting bracket 6, which is detachably fixed to the material collecting cover 2 through a U-shaped piece, and the dust collecting cover 7 is placed in the mounting bracket 6.

[0033] In order to further enhance stability, the mounting bracket 6 may be detachably provided with a reinforcing flange 61 .
