In this embodiment, the used paper apparatus may be any apparatus that can produce used paper, such as a printer or the like. The shredded paper fan 1 is malleation shredded paper fan 1, and it is a centrifugal fan who has improved the impeller, can inhale the note that the fan was inhaled to the negative pressure and fully smash and carry into the shredded paper pipeline of mixing pressure with malleation, and the effect is smashed the incessant long note of web press exhaust into the segment to prevent that the note from twining in the pipeline (discovery long note winding is the leading cause of jam in the practice), and the farther wind speed loss is bigger apart from negative-pressure fan 52 in addition, and shredded paper centrifugal fan's supplementary malleation can compensate the phenomenon that distal end wind speed is not enough.

The design principle of the mixed pressure shredded paper conveying pipeline 2 is as follows:

(1) determination of levitation and operating speeds

The property of pneumatic transmission is mainly to recover the leftovers in the production process to a designated place by pneumatic transmission, and the purpose of no pollution to the indoor and outdoor environment is achieved. According to the fact that conveyed materials are paper edge strips in strings, the weight of a large paper strip string is 50-60 g generally, in the conveying process, the paper edge strips are easy to be coagulated into paper groups in a pipeline due to mutual intersection, if the working speed is low, the paper strip string is easy to block in the conveying pipeline, the conveying system stops running, the pipeline is manually dismounted to remove obstacles for continuous use, therefore, when the suspension speed and the working speed which is higher than the suspension speed are considered, special treatment is needed, and according to observation and test in practice, the working speed range of pneumatic conveying is 15-20 m/s. The pneumatic conveying pipeline in the design and transformation process is blocked for many times, so that the system cannot be used, and basically cannot be blocked after repeated transformation and experiments.

(2) Determination of the mixing ratio m

Definition of the mixing ratio: the weight ratio of the transport material (G) to the transport air (Ga) is represented by the formula:

m＝G/Ga (1)

the practical significance of controlling the parameters lies in that the size of the conveyed material quantity G is matched with the diameter (D) of a designed system pipeline, or the size of the conveyed material quantity on the unit section of the air pipe has great influence on whether a pneumatic conveying system of a printing factory can normally operate without blockage, and if the value m is larger, the conveying pipeline is easy to be blocked and cannot normally operate according to the operation rule of the paper slip strings. According to the experience of the authors, the value of m is generally between 0.06 and 0.1.

It can also be imagined intuitively that even if the pipe diameter of a certain value is ensured to be sufficient in conveying working speed, the material quantity cannot be conveyed without limit, and the method is especially obvious for paper strip strings. The relation for determining the conveying pipe diameter (D) is given below:

D＝√4G/m·π·γ·υ·3600 (2)

d-pneumatic conveying pipe diameter (m)

G-weight of conveyed material (kg/h)

m-mixing ratio

π―3.1416

Gamma-delivered air weight (kgf/m)²)

Upsilon-the working speed (m/s) of the conveyed material.

For the mixed pressure shredded paper conveying pipeline 2, the size of the paper quantity generated in the process must be correctly determined before the design, the reliability of the design parameter is provided, the correct design and calculation of the pneumatic conveying system are very important, and the formula (2) shows that the size of G directly influences the air quantity and the conveying pipe diameter of the system, so that the size is large, the energy waste is large, and the system runs at a high speed; if the size is small, the system may be clogged and stopped, which makes it difficult to use the system normally, resulting in a failure in design.

When the waste paper collection system works, only the waste paper collection control device needs to open the paper shredding fan, the paper shredding separator, the dust filter and the negative pressure fan, if corresponding parameters need to be set, only the online setting is needed, manual operation on equipment corresponding to the site is not needed, and the operation complexity is reduced.
