The pneumatic output system 2 is configured to pneumatically convey the used paper in the used paper collecting box 1 to the used paper processing apparatus 3 for processing. The used paper recycling apparatus further includes a recovery mechanism 4 connected to the used paper processing apparatus 3 and configured to recycle the used paper processed by the used paper recycling apparatus 3.

The pneumatic output system 2 comprises a fan 20 and a pneumatic conveying pipeline 21. The fan 20 is connected with the input end of the waste paper collecting box 1 through a pneumatic conveying pipeline 20. The output end of the waste paper collecting box 1 is connected with the input end of the waste paper processing device 3 through a pneumatic conveying pipeline 21. The wind pressure of the fan 20 of this embodiment is greater than 0.1 Mpa. The diameter range of the pneumatic conveying pipeline 21 is 200 mm. The actual force blower 20 is a roots blower.

The waste paper collecting boxes 1 comprise a plurality of waste paper collecting boxes 1, the input ends of the waste paper collecting boxes 1 are connected with the fan 20 through pneumatic conveying pipelines 21, and the output ends of the waste paper collecting boxes 1 are connected with the input end of the waste paper processing device 3 through pneumatic conveying pipelines 21. The plurality of used paper collecting boxes 1 include a first used paper collecting box 11, a second used paper collecting box 12, and a raw paper dust collecting box 13.

The recovery mechanism 4 includes a conveying device 40 and a rotary kiln 41, an input end of the conveying device 40 is provided corresponding to an output end of the used paper processing apparatus 3, and an output end of the conveying device 40 is provided corresponding to the rotary kiln 41. The conveying device 40 is provided to be able to convey the used paper processed by the used paper processing device 40 to the rotary kiln 41. The conveying device 40 of the present embodiment conveys the used paper processed by the used paper processing device 3 to the rotary kiln 41 by belt drive.

The used paper processing apparatus 3 includes an input port 31, an output port 32, and a processing chamber 33 communicating with the input port 31 and the output port 32. A material stopper 330 is arranged in the processing cavity 33, and the material stopper 330 can rotate under the action of the airflow and hit the waste paper input into the processing cavity 33. The stopper 330 is disposed at one side of the lower portion of the input port 31, and includes a fixed shaft and an impeller 301 mounted on the fixed shaft and capable of rotating, and the impeller 301 can flap waste paper.

The conveying device 40 is provided to convey the used paper processed by the used paper processing device 3 to the rotary kiln for recycling.

When the waste paper recycling device for gypsum board production in the embodiment works, the fan 20 is started, the pneumatic conveying pipeline 21 conveys the pneumatic generated by the fan 20 to the waste paper collecting box 1, and the waste paper collected by the waste paper collecting box 1 is blown to the waste paper processing device 3 through the pneumatic conveying pipeline 21. The stopper 30 in the used paper processing apparatus 3 is rotated by the action of the air force to flap the used paper entering the used paper processing apparatus 3 to disperse the used paper, thereby preventing the problem that the used paper entering the used paper processing apparatus 3 is piled up and cannot be thoroughly processed. The used paper passing through the used paper processing apparatus 3 is conveyed to the rotary kiln 41 by the paper conveying apparatus 40.

The embodiment of the invention provides a gypsum board production system, a gypsum board production line and a waste paper recycling device described in the embodiment I. The gypsum board production line comprises a first control section, a second control section, a third control section and a raw material control section.

The first waste paper collecting box 11 is arranged at the first control section and is used for collecting waste paper generated by the first control section; the second used paper collecting box 12 is provided in the third control section for collecting used paper produced in the third control section; the raw material paper scrap collecting box 13 is arranged at the raw material control section and used for collecting waste paper produced by the original end. The rotary kiln 41 is arranged at the raw material control section to recycle and separate the gypsum boards.

The main function of the raw material control section is to complete the calcination process of the desulfurized gypsum. The desulfurized gypsum is transported via a feeding belt to a rotary kiln 41 for calcination, in which the free water and 1.5 crystal waters are dried off to form mature gypsum (hemihydrate gypsum). The calcined gypsum is input into a ball mill for grinding through equipment such as a rotary screen, a conveying reamer and a bucket elevator, and is finally conveyed into a storage bin for later use through the cooling effect of a cooler. Because unqualified gypsum boards need to be recycled, the method is that the crushed gypsum boards are mixed with desulfurized gypsum and enter the rotary kiln 41, and a rotary screen of the rotary kiln 41 is used for primarily screening the desulfurized gypsum boards to screen out large mask paper.

The first control section is mainly used for completing the forming process of the gypsum board. The plaster of paris is extracted from the silo, passes through the fine screen of the rotary kiln 41, is metered by an electronic scale and then enters a mixer together with auxiliary materials, water and other materials for mixing. And gypsum slurry is discharged from the discharge port, is wrapped by the upper and lower layers of protective paper, and is conveyed to the second control section direction through the forming belt conveyor.

The second control section finishes wet cutting and turning of the gypsum board and conveys the gypsum board into the dryer for drying the gypsum board.

And the third control section finishes cutting, packaging and stacking of finished gypsum boards. The scrap is cut and crushed at the same time, and is collected by a dust collector (used paper collecting box 12) of the third control section. And a rotary screen of the rotary kiln 41 is arranged at the position of the dust collector to screen out the paper scraps.

According to the embodiment of the invention, the waste paper produced by different outputs of the gypsum board production line can be automatically and uniformly treated, recycled and reused by arranging the pneumatic output system, so that manual carrying is avoided, and the efficiency is high.
