Description

Technical Field

[0001] This utility model relates to the field of fluidized solidified soil processing, and more specifically, to a material distribution structure for a grinding mill. Background Technology

[0002] Construction waste disposal remains a persistent challenge. Due to the large proportion of construction waste, traditional landfill methods are not environmentally friendly and can lead to ground subsidence. Furthermore, traditional backfilling methods require layered compaction with high density requirements, which is difficult to achieve in confined spaces, resulting in extended construction periods and increased labor costs. Moreover, traditional materials such as sand, gravel, and earthwork have discrete cavities, and insufficient compaction can easily lead to settlement and ground subsidence. Therefore, fluidized bed solidification has become the main method for handling construction waste in the current construction industry. Fluidized bed solidification uses waste soil and slurry as raw materials to achieve internal recycling within the project, reducing sand and gravel mining and cement usage to meet the requirements of low-carbon economy.

[0003] Currently, in the processing of fluidized solidified soil, excavators are typically used to dig up construction waste, which is then crushed. The crushed material is then placed in a mixer and mixed with water, additives, etc., to form fluidized solidified soil for backfilling.

[0004] The above method has the following drawbacks: due to the wide variety of construction waste and the significant differences in soil quality in different regions, such as sand, clay, and even steel bars from the construction site, the current method relies solely on crushing and mixing. Since the crushed waste is still in a gravel state, the resulting fluidized solidified soil is prone to segregation, bleeding, and stratification, meaning that it cannot achieve a fully mixed and uniform state of mud and water. As a result, the soil structure is poor when backfilling. In addition, the hard fragments such as steel bars contained in the construction waste can easily damage the equipment.

[0005] In order to process construction waste into smaller particles for fluidized solidification, the applicant proposed to use grinding instead of crushing. During grinding, the pre-crushed construction waste particles need to be placed into the grinding roller groove for grinding. However, how to evenly introduce water and crushed particles into the grinding groove for grinding has become a technical problem. Utility Model Content

[0006] The main objective of this application is to provide a material distribution structure for a pulping machine, which uniformly disperses particles through a material distribution disc assembly, and then the water distribution structure uniformly distributes water while rinsing off any remaining material on the material distribution disc.

[0007] To achieve the above objectives, in a first aspect, this application provides a material distribution structure for a pulp refiner, comprising a housing, a water distribution structure disposed on the top of the housing, a grinding roller assembly rotatably disposed within the housing, a grinding groove formed within the housing and cooperating with the grinding roller assembly, and a material distribution disc assembly fixedly disposed on the top of the grinding roller assembly. The water distribution structure includes water outlet pipes evenly distributed circumferentially on the top of the housing, and the material distribution disc assembly includes a material distribution disc body and a plurality of material discharge ports formed on the edge of the material distribution disc body, wherein the water outlet pipes are arranged in a one-to-one correspondence with the material discharge ports.

[0008] Optionally, the fabric tray body is conical.

[0009] Optionally, a baffle is detachably provided on the edge of the fabric tray body, and the material discharge port is opened on the baffle.

[0010] Optionally, the fabric tray body has at least a plurality of first mounting holes and second mounting holes along its radial direction, and the baffle is fixedly mounted on the fabric tray body through the first mounting holes or the second mounting holes.

[0011] Optionally, the water outlet pipe and the material discharge port are arranged alternately.

[0012] Optionally, a crusher is also connected to the housing, and the crusher is connected to the housing through a crushing inlet, which is located between the water distribution structure and the material distribution plate assembly.

[0013] Optionally, the grinding roller assembly includes a central shaft body that is rotatably disposed, at least two mounting fins that are radially fixedly disposed on the central shaft body, and grinding rollers that are vertically fixedly disposed on the corresponding mounting fins, with the fabric disc body fixedly disposed on the top of the central shaft body.

[0014] This utility model provides a material distribution structure for a pulp mill. Compared with the prior art, its advantages are as follows: In order to solve the problem of simultaneous and uniform water and material distribution, and to ensure that there is less particle material left on the material distribution disc, thus improving the pulping efficiency while ensuring the uniformity of the pulping, the water distribution structure is set at the top, and the water outlet pipe simultaneously discharges water to form a water curtain. This allows the material to be evenly distributed around the shell and finally fall evenly into the grinding trough. The particle material on the material distribution disc falls evenly from the discharge port under the action of its own weight and centrifugal force. For the small amount of particles left on its surface, the water curtain washes them away, so that the particle material falls completely into the grinding trough for pulping. This is not only highly efficient but also has good stability. Attached Figure Description

[0023] In addition, the term "multiple" should mean two or more.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-2 As shown, a material distribution structure for a pulping machine includes a housing 1, a water distribution structure disposed on the top of the housing 1, a grinding roller 10 assembly rotatably disposed within the housing 1, a grinding groove 9 formed within the housing 1 and cooperating with the grinding roller 10 assembly, and a material distribution disc assembly fixedly disposed on the top of the grinding roller 10 assembly. The water distribution structure includes water outlet pipes 2 evenly distributed circumferentially on the top of the housing 1. The material distribution disc assembly includes a material distribution disc body 4 and a plurality of material drop ports 6 formed on the edge of the material distribution disc body 4. The water outlet pipes 2 and the material drop ports 6 are arranged in a one-to-one correspondence.

[0026] The material feeding disc body 4 is conical. With the conical shape of the material feeding disc body 4, when the crushed particles fall, the crushed particles can be dispersed in all directions due to the cone shape. Moreover, as the material feeding disc body 4 rotates with the central axis, the centrifugal force generated at the same time disperses the particles in all directions, and finally falls from the discharge port 6, thus achieving uniform material feeding.

[0027] A baffle 5 is detachably installed on the edge of the material feeding disc body 4. The material discharge port 6 is opened on the baffle 5. The material feeding disc body 4 has at least a plurality of first mounting holes and second mounting holes along its radial direction. The baffle 5 is fixedly installed on the material feeding disc body 4 through the first mounting holes or the second mounting holes. By installing the baffle 5 in different positions, the gap between the baffle 5 and the inner wall of the shell 1 can be adjusted, thereby adapting to different crushed particles, thereby achieving controllable material size, and thus filtering hard particles according to actual conditions.

[0028] The water outlet 2 and the material drop port 6 are arranged alternately. Since the water curtain formed by the water outlet 2 eventually enters the grinding tank 9 through the material drop port 6, the alternate arrangement can wash away a small amount of particles left on the surface of the cloth disc body 4 and finally fall into the grinding tank 9 through the material drop port 6. Moreover, water and particles enter the grinding tank 9 together, which greatly improves the grinding efficiency and effect.

[0029] Preferably, a crusher 3 is also connected to the housing 1, and the crusher 3 is connected to the housing 1 through a crushing inlet, which is located between the water distribution structure and the material distribution plate assembly.

[0030] Preferably, the grinding roller 10 assembly includes a central shaft body 7 that is rotatably disposed, at least two mounting fins 8 that are radially fixedly disposed on the central shaft body 7, and a grinding roller 10 that is vertically fixedly disposed on the corresponding mounting fins 8, and the fabric disc body 4 is fixedly disposed on the top of the central shaft body 7.

[0031] Specifically, considering cost, efficiency, and stability, the number of grinding rollers 10 is preferably three. This ensures that the three grinding rollers 10 are evenly distributed within the circular grinding groove 9, resulting in good stability. Furthermore, the simultaneous grinding by the three grinding rollers 10 improves efficiency.

[0032] The central shaft body 7 is driven to rotate by the drive motor, which in turn drives the grinding roller 10 to rotate, thereby grinding the crushed particles that fall into the grinding trough 9. The crushed particles and water fall into the grinding trough 9 together, so that not only can the crushed particles be ground, but they can also be mixed with water to form a slurry, so that no further stirring is required. In addition, the grinding speed can be controlled by setting a speed reducer.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
