The utility model action principle is: Start working from the feeding port to join paper materials from the filler adding an appropriate amount of white water, open the return line valve, high-speed rotation of the cutter in the water under the impetus of the paper materials produce strong impact and compression, paper materials are broken solution, crushing the paper material with the water in the cutterhead centrifugal force, through the groove with cutter cover consisting of a special channel, enter the cutter housing cavity, and then through the discharge pipe on the return pipe, back into the slurry tank; Again and again, passing the slurry was labeled paper materials; case, turn off return valve, open the discharge valve, the slurry will be automatically discharged through the discharge pipe into the slurry tank, eliminating the pump, grinding machines and other equipment fluffer, to complete the entire pulping process.
The utility model relative to the prior art has the following advantages and effects: (1) conventional pulper work, work surface in the presence cutter has to be shredding shredding material and the material in the same space and out of the question, as has been shredding material barriers, reducing treat shredding cutter and blade material impact times and squeeze opportunities. The utility model clever use of the centrifugal force generated by rotation of the cutter is designed with a groove cutter cover, composed of a special cross-section of the channel, can be automatically isolated from the shredded material and the material to be shredded paper, paper-less than the channel cross-section to quickly pass, greater than the channel cross-section paper material left in the tooth surface, and continue with the cutter blade impact and compression; This cutter can be continuously "eat" into the material to be shredded, "spit out" has shredding material, thus shortening the pulping time, and the crushing of the slurry evenly; with the same volume and power compared to conventional pulper, crushing a box of pulp, about 50% of the time can be shortened. (2) Since slurry flow channel design has been optimized so the slurry after crushing good quality, no scraps of paper, without an additional secondary crushing equipment. (3) due to centrifugal force generated by the cutter disc rotation naturally, it will not increase the power, and reduce energy consumption; same time as the full advantage of the centrifugal force, the pulp slurry tank can be discharged without pump. (4) the lower part of the headbox into a half cylinder, the upper half of a rectangular parallelepiped, a cylindrical surface is provided below the bottom of the slurry and a slag discharge hopper mouth, this structure principles of fluid mechanics, the slurry must flow The cutter and cutter cover to achieve the purpose of rapid crushing slurry, slurry flow was smooth no dead ends, debris in the water under the action of all the sewage into the bucket through Cleaner mouth, can be easily cleaned, thus eliminating the need for Grit machine, simplifying the pulping process, users can save equipment investment, and reduce energy consumption.

Specific embodiments
Below with reference to Examples and drawings, the present utility model described in further detail, but the present embodiment of the utility model is not limited thereto.
Examples 1 to 4 shows a specific structure of the utility model from Figure 1 and Figure 2, the hydraulic pulper mainly by the headbox 1, the main frame 2, the motor 3, the bearing seat 4, spindle 5, 6 cutter, cutter cover 7, the feed pipe 8, other components of the return pipe 9; the slurry tank 1 to the upper part of a rectangular parallelepiped, the lower half cylinder, as shown in Figure 2; in the slurry tank 1 has added on the upper surface and a rectangular outlet 1-4 1-1 feed port in the bottom of the slurry tank 1 provided with a rectangular cylindrical surface of the discharge hopper 1-2 (see Figure 1), the bottom of the discharge hopper 1-2 a slag discharge port 1-3, slurry tank 1 with a side shaft 5, the cutter 6 is fixed on the shaft 5, shown in Figure 3; 6 on the processing of the cutter tooth blade 6 with 6-1 and -2, shown in Figure 4; 6 out of the cutter cover 7 is provided with a cutter, the cutter cover 7 is fixedly connected with the slurry tank 1; cutter cover 7 is provided with the feed pipe 8, the feed pipe 8 is equipped with a reflux tube 9, one end of the return pipe 9 is connected to the discharge pipe, the other end is connected with the upper part of the headbox 1, the cutter cover 7 in the outer end portion of the shaft 5 with the pulley 10 by a belt connected to the motor 3. The cutter 6 rounded structure, 6-1 cutter was pentahedral, distributed in the circumferential cutter 6; 6-1 composed by an adjacent teeth twice sipes 6-4; groove bottom 6-4 6 face flush cutter, cutter 6 6-2 middle with four blades, cutter 6 is the center of the mounting hole with keyway 6-3, in the back of the cutter 6 settings promising improved rigidity and design flange. The cutter cover 7 was cylindrical, with its inwardly projecting end flange 7-1, 7-1 the height of the projecting flange 6 with the cutter; 7-1 in the inner flange, located There are stairs with cutter 6 together form slurry flow channel, cutter cover 7 has to prevent leakage of plasma inside the annular seal groove 7-2, the annular seal groove is provided with a seal packing 7-3. The cutter cover 7 with a tangent to the wall of the feed pipe 8, the feed pipe 8 is connected to a return pipe 9, a reflux pipe 9 is also connected with the upper portion of the headbox 1, the structure is formed reflux, its role is to crushing incomplete slurry headbox sent back again within a broken solution. 水力碎浆机英文文献和参考文献(5):http://www.751com.cn/fanyi/lunwen_16969.html
