Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 shows a schematic structural diagram of a double-disc refiner of the present invention, referring to fig. 1: to the utility model discloses an embodiment, a paper products production is with double-disk refiner, including mill pulp room 1, inlet pipe 2 and discharging pipe 3 with mill pulp room 1 intercommunication, above-mentioned mill pulp room 1 has set gradually first quiet mill 4 from a left side right side, first mill 5 that moves, the quiet mill 6 of second, the quiet mill 7 of third, mill 8 is moved to the second, the quiet mill 9 of fourth, above-mentioned inlet pipe 2 has two and is located the both ends of mill pulp room 1 respectively, above-mentioned first quiet mill 4 and the quiet mill 9 of fourth are hugged closely above-mentioned mill pulp room 1's both ends wall setting respectively, and be provided with the through-hole that is linked together with above-mentioned inlet pipe 2 on it, above-mentioned first mill 5 that moves and the second moves the both sides of mill 8 and all is provided with the gerar 11, have the clearance between above-mentioned gerar 11. In the embodiment, the material to be refined enters the refining chamber from the feeding pipes at two sides of the refining chamber, firstly enters between the first static refining disc and the first movable refining disc from the feeding pipe at one side for refining, enters between the fourth static refining disc and the second movable refining disc from the feeding pipe at the other side for refining, the material can continuously enter between the first movable refining disc and the second static refining disc and between the second movable refining disc and the third static refining disc for further refining after refining, finally enters into a channel between the second static refining disc and the third static refining disc, and is discharged from the discharging pipe to finish the refining operation, the useful pulp after being refined will gradually float upwards due to the action of gravity, while the pulp containing impurities or with thicker texture will sink or continue to pass through the grinding disc for further grinding, by arranging a plurality of grinding discs and combining the movable grinding disc and the static grinding disc, the double-disc pulping machine has higher working efficiency and better quality of ground pulp; meanwhile, under the matching action of various grinding discs, the fibers in the pulp are thinner and softer, and the produced paper product is softer in texture.

Further, in order to smoothly discharge the slurry, the third stationary grinding disc 7 and the fourth stationary grinding disc 9 are fixed to the top of the grinding chamber 1, and the lower end portions thereof are spaced from the grinding chamber 1, and the discharge pipe 3 is provided on the top wall of the grinding chamber 1 between the third stationary grinding disc 7 and the fourth stationary grinding disc 9.

Furthermore, the two side surfaces of the first movable grinding disc 5 and the second movable grinding disc 8 are both provided with through holes 12 penetrating through the grinding discs, the inlet end of each through hole 12 is far away from the axle center of the first movable grinding disc 5 or the second movable grinding disc 8, and the outlet end of each through hole 12 is close to the axle center of the first movable grinding disc 5 or the second movable grinding disc 8. The first movable grinding disc and the second movable grinding disc are provided with through holes, the through holes are not communicated vertically, but are communicated obliquely, so that pulp flows from a previous channel to a next channel to be continuously ground, the inlet end of each through hole is far away from the axle center, and the pulp can gradually move outwards under the action of centrifugal force, so that the pulp subjected to grinding is continuously ground from the central position which can flow from the through hole to the next channel, and the pulp is ground more uniformly under the action of the next channel.

Further, the plurality of perforations 12 are uniformly arranged around the axial center of the first movable grinding disc 5 or the second movable grinding disc 8. The plurality of through holes are arranged, so that the pulp can conveniently flow in the two pulp grinding channels. The pulp continuously flows from one side of the first movable grinding disc and the second movable grinding disc to the other side, namely enters the next pulp grinding channel to continuously grind the pulp, the pulp quality is better through the pulp grinding of the two pulp grinding channels, and the texture of the manufactured paper product is softer and more comfortable.

Further, as shown in fig. 2, the grinding teeth 11 are divided into long grinding tooth groups 111 and short grinding tooth groups 112, and the long grinding tooth groups 111 and the short grinding tooth groups 112 are alternately arranged. The grinding teeth arranged on the movable grinding disc are mainly used for grinding fibers into pulp, and the long grinding teeth and the short grinding teeth are reasonably distributed, so that the number of the grinding teeth is increased, the pulp is finer, the pulp is softer, and the produced paper towels are softer.

Further, the long grinding teeth 111 are located between the adjacent through holes 12, and the long grinding teeth in the long grinding teeth 111 extend from the edge of the grinding disc toward the axial center and gradually shorten along the rotation direction thereof. The distribution structure of the long grinding tooth group is limited, so that the grinding material is more sufficient.

Further, the short set of grinding teeth 112 is located between the edge of the grinding disc and the perforations 12 and extends from the edge of the grinding disc towards the perforations 12. The structure of the short sets of grinding teeth is defined so that the grinding is facilitated.
