Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of papermaking refiners, and in particular relates to a conical mould used for a papermaking refiner. Background Art
[0002] When processing papermaking raw materials, a pulping machine is required to grind the raw materials. The conical mold used in the current pulping machine is composed of an inner mold and an outer mold. Inclined grinding stripes are set on the opposite surfaces of the inner and outer molds, and there is a distance between the stripes. The rotating mold drives the stripes to rotate to cut and grind the material. The material enters from the large diameter end. As the grinding progresses, the particle volume of the material decreases and moves synchronously to the small diameter end. The gap between the stripes plays a role in material transportation. However, in reality, the subsequent material will squeeze the material between the stripe gaps to move backward. Most of the material can enter the gap between the inner and outer molds from the stripe gaps and be ground, but there is still a part of the material that continues to move backward in the stripe gaps. This part of the material cannot be effectively ground, which not only affects the effect of material refining, but also has the risk of causing local blockage of the pulping machine.

[0018] See also Figures 1-4 The utility model provides the following technical solutions: a conical mold for a papermaking pulping machine, comprising a conical inner mold body 1, three primary grinding assemblies 2 are provided on the side wall of the conical inner mold body 1, and three circulating grinding assemblies 3 are staggered with the three primary grinding assemblies 2 on the outer wall of the conical inner mold body 1. The circulating grinding assembly 3 includes five guide grinding stripes 31, and the bottom ends of the three guide grinding stripes 31 distributed at intervals are fixedly connected to "W"-shaped feed blocking stripes 32, and the top ends of the other two guide grinding stripes 31 are fixedly connected to "U"-shaped discharge blocking stripes 33. A horizontal blocking stripe 4 is provided above the primary grinding assembly 2, and an arc-shaped guide stripe 41 is fixedly connected to one side of the horizontal blocking stripe 4, and the arc-shaped guide stripe 41 is fixedly connected to the "U"-shaped discharge blocking stripe 33.
[0019] In this embodiment: the conical inner mold body 1 is installed at the corresponding position of the pulping machine. During use, the raw material is fed through the large-diameter end of the conical inner mold body 1. When the raw material passes the corresponding position of the inclined grinding stripes 21, it is preliminarily ground under the cooperation of the inclined grinding stripes 21 and the matching stripes 51. When the particles meet the discharge standard, the raw material is discharged through the gaps between the horizontal blocking stripes 4, the arc-shaped guide stripes 41, the "U"-shaped discharge blocking stripes 33 and the matching stripes 51 and the matching transverse stripes 52. Large particles that do not meet the discharge standard are intercepted by the horizontal blocking stripes 4, and the large-particle raw materials are guided to the corresponding position of the guide grinding stripes 31. Under the extrusion of subsequent materials, the large-particle raw materials are circulated and transported in the internal paths of the guide grinding stripes 31, the "W"-shaped feed blocking stripes 32 and the "U"-shaped discharge blocking stripes 33, so that the large-particle raw materials can flow back to the large gap position again. And it is transported over a long distance at a large gap position. Under the high-speed rotation of the conical inner mold body 1, the large-particle raw material enters the gap between the matching stripes 51 and the guide grinding stripes 31 again, so that the large-particle raw material transported to the small diameter end along the stripe gap can re-participate in the grinding process, and is ground into small-particle raw material by the matching stripes 51 and the guide grinding stripes 31, and is discharged from the small diameter end after grinding, thereby improving the refining effect of the device, solving the problem that the particles transported to the small diameter end between two adjacent inclined grinding stripes 21 cannot enter the gap between the matching stripes 51 and the inclined grinding stripes 21, and thus cannot be effectively ground, so as to avoid the small diameter end of the grinding gap being blocked by large-particle raw material. In the process of material circulation and transportation, the "W"-shaped feed blocking stripes 32 play a blocking role, which can hinder subsequent feed and reduce the obstruction of subsequent feed to the movement of large-particle raw materials in the circulation path.
[0020] The outer wall of the conical inner mold body 1 is provided with three primary grinding areas 11, and the outer wall of the conical inner mold body 1 is provided with three circulating grinding areas 12 staggered with the three primary grinding areas 11. The three primary grinding areas 11 correspond to the positions of the three primary grinding components 2 respectively, and the three circulating grinding areas 12 correspond to the positions of the three circulating grinding components 3 respectively; the three primary grinding areas 11 and the three circulating grinding areas 12 correspond to the primary grinding components 2 and the circulating grinding components 3 respectively, and the three primary grinding components 2 and the three circulating grinding components 3 are cyclically alternated.
[0021] The primary grinding assembly 2 includes a plurality of inclined grinding stripes 21 , which are all fixedly connected to the conical inner mold body 1 ; the inclined grinding stripes 21 can cooperate with the matching stripes 51 to grind the raw material.
[0022] A horizontal grinding stripe 22 is fixedly connected to one side of the inclined grinding stripe 21 located in the middle, and the horizontal grinding stripe 22 is fixedly connected to the conical inner mold body 1; by setting the horizontal grinding stripe 22, the material can be guided so that the material can be transported to the corresponding area of the circulating grinding component 3.
[0023] A dense grinding stripe 34 is provided between two adjacent guide grinding stripes 31 , and the dense grinding stripe 34 is fixedly connected to the conical inner mold body 1 ; by providing the dense grinding stripe 34 , the grinding effect of large-particle raw materials during the circulating conveying process can be increased.
[0024] A number of supplementary grinding stripes 35 are provided on one side of the lowest guide grinding stripe 31, and the several supplementary grinding stripes 35 are fixedly connected to the outer wall of the conical inner mold body 1; by providing the supplementary grinding stripes 35, the blank area between the circulating grinding component 3 and the primary grinding component 2 can be supplemented, and through the angle design, the material discharged from the gap between the supplementary grinding stripes 35 will enter the corresponding position of the primary grinding component 2, thereby improving the grinding effect of the material.
[0025] An outer fitting sleeve body 5 is provided on the outside of the conical inner mold body 1, and a fitting stripe 51 is fixedly connected to the inner wall of the outer fitting sleeve body 5. The distance between the fitting stripe 51 and the conical inner mold body 1 gradually decreases from bottom to top, and a fitting transverse stripe 52 is fixedly connected to the inner wall of the outer fitting sleeve body 5; the fitting stripe 51 can cooperate with the primary grinding component 2 and the circulating grinding component 3 to grind the material, and the fitting transverse stripe 52 can cooperate with the horizontal blocking stripe 4, the arc-shaped guide stripe 41 and the "U"-shaped discharge blocking stripe 33 to intercept large-particle raw materials, and only small-particle materials that meet the standard can be discharged. The gap corresponding to the large-diameter end position is large, so that the large-diameter material that has just entered the grinding area can enter the gap. As the grinding proceeds, the volume of the material gradually decreases, and the smaller gap can be used to grind the material more finely.
[0026] The working principle and use process of the utility model are as follows: the raw material is fed through the large-diameter end of the conical inner mold body 1, and when the raw material passes through the corresponding position of the inclined grinding stripes 21, it is preliminarily ground under the cooperation of the inclined grinding stripes 21 and the matching stripes 51. When the particles meet the discharge standard, the raw material is discharged through the gap between the horizontal blocking stripes 4, the arc-shaped guide stripes 41, the "U"-shaped discharge blocking stripes 33 and the matching stripes 51 and the matching transverse stripes 52. The large particles that do not meet the discharge standard are intercepted by the horizontal blocking stripes 4, and the large particle raw materials are guided to the corresponding position of the guide grinding stripes 31. The large particle raw materials are extruded in the subsequent materials. Under the action of the guide grinding stripes 31, the "W"-shaped feed blocking stripes 32 and the "U"-shaped discharge blocking stripes 33, the large-particle raw materials are circulated and transported in the internal paths, so that the large-particle raw materials can flow back to the large gap position again and be transported over a long distance at the large gap position. Under the high-speed rotation of the conical inner mold body 1, the large-particle raw materials enter the gap between the matching stripes 51 and the guide grinding stripes 31 again, so that the large-particle raw materials transported to the small diameter end along the stripe gap can re-participate in the grinding process, be ground into small-particle raw materials by the matching stripes 51 and the guide grinding stripes 31, and be discharged from the small diameter end after grinding.
