The hoop type supporting mechanism is used for supporting and fastening the hydrapulper and an installation foundation, adjusting the rod by screwing according to the field condition, adjusting the whole length of the supporting rod assembly, tensioning (or supporting) the bearing chamber and ensuring that no displacement or vibration occurs in transmission. The hoop type supporting mechanism of the embodiment is convenient, rapid and firm to clamp, has no fixed direction, and can move up and down and rotate randomly.

When the device works, 60-70-degree hot water is added into the tank body 1, and a proper amount of medicines and waste paper are added according to the process requirements. The motor 6 inputs power to drive the rotor 2 to rotate, the rotor 2 rotates to drive the pulp to form strong circulating turbulence, so that strong friction is generated between waste paper, the waste paper is dissociated into fibers, ink particles and oil stains are peeled and separated from the surfaces of the fibers under the action of friction between the fibers and chemicals, the subsequent process can be smoothly carried out, and the pulp with higher whiteness is produced by using the waste paper. The good pulp finally enters the fine pulp chamber through the sieve plate, is discharged from the pulp outlet pipe and enters the next working procedure. The heavy slag is periodically discharged from the heavy slag pipe 14. This is repeated.

And functional nozzles such as the heavy slag pipe 14, the dilution water pipe 16, the slurry outlet pipe 54 and the flushing water pipe 57 are remotely controlled by using a DCS system.

The high-concentration hydrapulper of the embodiment has the characteristics of high production capacity, low power consumption, convenience in use and maintenance and the like.
