The motor inputs power, a transmission belt drives a transmission shaft of the transmission mechanism to rotate, and the transmission shaft drives the cutter head to rotate. The pulp is broken up by the combined action of hydraulic shearing, friction between fibres and impact of cutter head. The good pulp enters the fine pulp chamber through the sieve plate and is finally discharged through the pulp outlet to enter the next working procedure.

The medium-concentration hydrapulper can be effectively suitable for the disintegration of relatively clean raw materials such as wood pulp and the like, and the concentration of the disintegrated pulp can reach 5 percent_~8 percent, good disintegration effect and greatly improved production efficiency, and is suitable for manufacturing clean paper pulp (such as toilet paper and the like).

Example two

The difference between the present embodiment and the first embodiment is the structure of the cutter head.

As shown in fig. 16 to 17, the cutter head of the present embodiment includes a plurality of hybrid fins uniformly arranged on the cutter head body 91 in the circumferential direction, the hybrid fins include suction fins 92 having a relatively high axial height and cleaning fins 93 having a relatively low axial height, the suction fins 92 and the cleaning fins 93 are alternately arranged in sequence, a bottom of the cutter head body 91 is provided with a bottom cutter 94 extending in the radial direction around the center thereof, and an inclined angle is formed between the bottom cutter 94 and the cutter head body 91 in the radial direction.

The suction fins 92 are of a radially outwardly spiral configuration and vary in cross-section from radially inward to radially outward. The root of the radially outer section 97 of the suction vane 92 is at an angle of 90-105 deg. to the base, preferably at an obtuse angle of 105 deg..

The section of the cleaning fin 93 changes gradually from inside to outside along the radial direction, and the root of the radial outer section 98 of the cleaning fin 93 forms an included angle of 90-105 degrees with the bottom surface, preferably an obtuse angle of 105 degrees. The cleaning fin 93 is provided with a blade 95 on its pulp facing side.

The bottoms of the suction type fins 92 and the cleaning fins 93 are provided with bosses 96 with certain widths, and the bottoms of the suction type fins 92 and the cleaning fins 93 are inclined planes, so that negative pressure can be generated during working, and the sieve plate can be cleaned and prevented from being blocked.

In this embodiment, a key groove is formed at the mounting hole of the cutter head body 91 for key connection with the driving shaft 31, and the connection is reliable. The contact part of the cutter disc 91 and the shaft shoulder of the driving shaft 31 is provided with a gasket group, and the clearance between the cutter disc and the sieve plate can be adjusted by adjusting the height of the gasket, so that the clearance between the cutter disc and the sieve plate reaches 1_~3mm。

In this embodiment, bed knife 94 and blade 95 all select wear-resisting stainless steel material to make for use, and bed knife 94 and cutter head body 91 welded connection, blade 95 and clearance fin 93 welded connection, can change, extension blade disc life-span.

In the present embodiment, the suction fins 92 and the cleaning fins 93 are arranged three by three.

When the cutter disc of the embodiment works, 3 higher blades are suction type blades, and strong vortex effect is generated during rotation, so that slurry is internally circulated, the contact between paper pulp and the cutter disc is increased, paper sheets are broken to the maximum extent, mechanical energy effectively acts on fibers to generate mild friction, collision and rubbing, and the pulping effect is improved; the lower of 3 is the cleaning fin, which generates high pressure during rotation, increases the throughput of the sieve plate and ensures the good pulp after being disintegrated to be discharged quickly. And the bed knife 94 is matched with the knife strips 42 on the sieve plate 4, so that the shearing and the cleaning are convenient.

The cutter head of the embodiment changes the structural type and the shape of the traditional cutter head, improves the efficiency, saves energy, reduces consumption and greatly improves the production capacity.
