[0002] In the production of fluidized solidified soil, solid waste materials such as tunnel boring machine slag, fine aggregates from construction waste, mineral powder, and fly ash are used on a large scale. This not only effectively utilizes solid waste resources but also plays a vital role in supporting environmentally friendly construction and resource recycling. During storage and transportation, the granular materials within the storage silo shell form a stable arched structure due to cohesion, friction, and other physical factors, hindering the smooth descent and transport of materials. This directly impacts the continuity and efficiency of the production process. In fine processing techniques requiring accurate metering and proportioning, this phenomenon can cause severe operational interruptions, affecting the performance and quality of the final product.

[0003] Therefore, there is an urgent need for an anti-arching structure integrated into the fluidized solidified soil production device. Through structural improvements, solid waste materials can be smoothly lowered and transported, thereby improving production efficiency. Utility Model Content

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figures 1 to 8 The structure shown for preventing solid waste material arching includes: The storage shell 1 has an inlet 11 and an outlet 12 at both ends. The storage shell 1 is divided into a storage section 13 near the inlet 11 and a guide section 14 near the outlet 12. The guide section 14 has multiple material filling ports 14a. It should be noted that the storage shell 1 can be made of various materials, such as wear-resistant steel, polytetrafluoroethylene coated steel plate, composite material shell, or other wear-resistant materials.

[0023] The stirring mechanism 2 is located inside the storage shell 1. It should be noted that the stirring mechanism 2 can have many shapes, such as a spiral, a single or multi-layer curved wing structure, a paddle shape, or other structures that can achieve the stirring effect.

[0024] The material handling mechanism 3 is located outside the guide section 14 and includes a frame 31 connected to the outside of the guide section 14, a drive assembly 32 connected to the frame 31, and a cutting element 33 connected to the output end of the drive assembly 32 and extending into the material handling port 14a. The cutting element 33 can be relatively close to or away from the inside of the storage housing 1. It should be noted that the shape of the cutting element 33 can be various, such as a blade shape, a strip shape, a triangle shape, or a grid shape.

[0025] In operation, the storage shell 1 receives solid waste material through the feed inlet 11. The material sequentially enters the storage section 13 located inside the shell for storage. In the storage section 13, the material gradually flows downwards due to its own weight and enters the guide section 14. The stirring mechanism 2 inside the guide section 14 agitates and loosens the material to break the cohesive force between particles, thereby preventing material accumulation and resulting in poor flow. Multiple straightening ports 14a are provided on the wall of the guide section 14, and the straightening ports 14a are connected to the external straightening mechanism 3. Structure 3 includes a frame 31, a drive assembly 32, and a cutting component 33. The drive assembly 32 drives the cutting component 33 towards the material preparation port 14a via the frame 31, extending the cutting component 33 into the guide section 14. The cutting component 33 can move relatively close to or away from the storage shell 1 in a specified direction, cutting and dispersing the accumulated material, breaking its arched structure, and ensuring that the material can fall smoothly to the discharge port 12. Through the flexible operation of the cutting component 33, blockage problems caused by excessive material particles or uneven pressure can be effectively avoided, maintaining the continuous flow of the material. After the material is mixed and processed by the material preparation mechanism 3 inside the guide section 14, it is smoothly discharged through the discharge port 12, completing the material conveying process and realizing the improvement of the flowability of solid waste materials and the suppression of arching.

[0026] This utility model uses a storage shell 1 with an inlet 11 and an outlet 12 for material entry and exit, making material flow smoother. The stirring mechanism 2 can effectively turn the material and break the cohesion of solid waste in the storage section 13. By setting multiple material straightening ports 14a and the coordination of the material straightening mechanism 3, the material straightening mechanism 3 applies external force to the solid waste in the guide section 14 in the storage shell 1, ensuring that the material is concentrated in the guide section 14 and discharged smoothly. The material straightening mechanism 3 extends into the material straightening port 14a to cut and disperse the accumulated solid waste, avoiding the clogging problem common in traditional equipment and further reducing the arching phenomenon.

[0027] The accumulation and arching of materials within the storage silo not only affects flowability but can also lead to system blockage and reduced efficiency. To ensure that the solid waste cut by the cutting component 33 can move towards the discharge port 12, such as... Figure 1 , Figure 5As shown, the material handling mechanism 3 also includes a transverse movement component 34, comprising a slider 34a fixedly connected to the frame 31 and a slide rail 34b fixedly connected to the outer wall of the guide section 14. The slider 34a can move relatively closer to or further away from the discharge port 12 on the slide rail 34b. Through the design of the slider 34a and the slide rail 34b, the cutting component 33 can precisely cut the accumulated solid waste when entering the storage shell 1. The transverse movement mechanism is not limited to longitudinal movement, but can also laterally push the cut solid waste material toward the discharge port 12. The transverse movement mechanism, combined with the operation of the cutting component 33, not only breaks the cohesive arch structure of the particles, but also effectively guides the material flow toward the relatively low-resistance discharge port 12, improving the smoothness of material falling and being discharged.

[0028] During the storage and transportation of solid waste materials, especially in the processes of breaking up and dispersing, material leakage and environmental pollution can occur. For example... Figure 4 , Figure 7 As shown, a seal 35 is provided at the contact point between the storage chamber shell 1 and the cutting component 33. The seal 35, with its high-efficiency sealing performance, is positioned at this contact point to form a complete enclosed space, preventing material spillage during processing. The seal 35 ensures that when the cutting component 33 extends into the storage chamber for cutting and dispersing, it effectively prevents material and gas leakage, reduces dust pollution and environmental impact, and maintains stable internal system pressure. It should be noted that the seal can take many forms, including O-rings, lip seals, U-shaped or V-shaped seals, or other types of seals.

[0029] Arching mostly occurs in the guide section 14, where the arch adheres to the inner wall of the guide section 14. To facilitate the discharge of the arched solid waste, such as... Figure 1 , Figure 2 As shown, the material straightening inlet 14a and the material straightening mechanism 3 are evenly arranged around the circumference of the guide section 14. The material straightening inlet 14a and the material straightening mechanism 3 are evenly distributed around the circumference of the guide section 14, which makes the processing of materials in the storage silo more comprehensive and balanced. Through multi-point collaborative system processing of solid waste materials, it is ensured that materials at any position can be cut, dispersed and guided to the discharge port 12 within the guide section 14. The even arrangement of the material straightening mechanism 3 allows the cutting component 33 to operate flexibly in different positions, thereby breaking the radial accumulation of materials and preventing local arching.

[0030] Traditional cutting components 33 typically employ simple straight or circular designs. These designs have limited cutting force when breaking up accumulated material, and cannot effectively penetrate and disperse concentrated material. For example... Figure 4 , Figure 7As shown, the end of the cutting component 33 facing the storage shell 1 has a triangular cross-section. This triangular end provides a sharp cutting point, allowing the cutting component 33 to more easily insert and penetrate the material upon contact, thus dispersing any bridging or knotting. This not only increases the cutting force and efficiency of the cutting component 33 but also enhances its stability and penetration within the material. The triangular end also provides greater spatial adaptability and cutting strength, ensuring rapid breaking down and encouraging material to fall even when faced with complex material properties.

[0031] While mechanical methods of breaking up arches can break up accumulations to some extent, their efficiency is often limited when dealing with dense or difficult-to-cut materials. For example... Figure 3 , Figure 6 As shown, it also includes an air jet assembly 4, comprising a through-hole 41 formed inside the cutting element 33, and an air compressor disposed outside the storage housing 1 and connected to the through-hole 41. High-pressure airflow is used to enhance the material dispersion effect. The airflow within the through-hole 41 can penetrate into the interparticle gaps of the material, dispersing the accumulated material through airflow pressure. The airflow not only enhances the physical cutting action of the cutting element 33 but also reduces interparticle adhesion and lowers the cohesive force of the material. The high-pressure airflow provides a driving force during material cutting, helping the particles move in the discharge direction. Combining the dual effects of pneumatic and physical cutting significantly improves the arch-breaking efficiency and material flowability.

[0032] Solid waste arches inside the storage silo shell 1. To break up this arching and reduce the risk of accumulation in the storage section 13, traditional mixing devices are often arranged along the extension direction of the silo. However, their mixing effect may not fully cover the entire material layer, especially when the material flow path changes, where insufficient mixing has a significant impact. (Reference) Figure 2 As shown, the stirring mechanism 2 is located at the connection between the storage section 13 and the guide section 14, and its extension direction is perpendicular to the extension direction of the storage shell 1. Using tangential flow, the material is thoroughly agitated perpendicular to the shell, ensuring that materials at different levels are effectively tumbled and loosened. This allows the stirring mechanism 2 to more accurately intervene in all aspects of the material, promoting the flow of materials at the bottom and middle of the material layer, achieving more uniform mixing and loosening. This increases the efficiency of material loosening and deagglomeration, reduces the risk of material accumulation due to incomplete local mixing, and thus improves the overall conveying smoothness of the system.

[0033] Material often accumulates on the inner walls of storage silos due to adhesion and friction, especially when the material flow path is not clearly defined, leading to material stagnation or accumulation in localized areas. For example... Figure 1 , Figure 2As shown, the inner wall of the storage tank shell 1 has a guide trough 15 extending from the feed inlet 11 towards the discharge outlet 12. The guide trough 15, extending from the feed inlet 11 towards the discharge outlet 12, clearly defines the flow path through its structure, reducing material adhesion to the inner wall and optimizing material flow. The guide trough 15 guides dispersed particles to a concentrated flow direction, reducing pressure dead zones caused by accumulation and facilitating smooth material flow to the discharge outlet 12.

[0034] In some embodiments of this utility model, the inner wall of the storage tank shell 1 has a polytetrafluoroethylene coating. The polytetrafluoroethylene coating on the inner wall of the storage tank shell 1 significantly reduces the adhesion between the material and the inner wall due to the coating's low friction and anti-stick properties.

[0035] According to a second aspect of the present invention, a fluidized bed solidification production apparatus is also provided, such as... Figure 8 As shown, it includes: Multiple storage tank shells 1, including inlet 11 and outlet 12; The conveying mechanism 5 is connected to the discharge port 12 of each storage shell 1; The metering mechanism 6 is located between the discharge port 12 and the conveying mechanism 5; The activator dispensing mechanism 7 includes a storage tank, a flow meter and a solenoid valve installed at the outlet 71 of the storage tank, a pH monitor installed inside the storage tank, and a delivery pump installed at the outlet 71. The mixing mechanism 8 is connected to multiple discharge ports 12 and outlets 71, and has a mixing component inside.

[0036] In the process of solid waste resource utilization, improving the efficiency of material mixing and solidification is crucial. However, traditional solidification production lines often suffer from inaccurate metering, uneven mixing, and insufficient reaction, leading to unstable final product performance. To address these technical problems, this invention provides a fluidized bed solidification production device, consisting of multiple storage tank shells 1. Each shell is equipped with an inlet 11 and an outlet 12 to flexibly handle various raw materials. The outlet 12 of the storage tank is connected to a conveying mechanism 5 to ensure continuous and synchronous material transport. A metering mechanism 6 is installed between the outlet 12 and the conveying mechanism 5 to accurately measure the proportions of different materials, ensuring the accuracy of the composition during the reaction process. This allows for more scientific mixing of raw materials and activators in subsequent steps, optimizing the reaction. The activator dispensing mechanism 7, through a storage tank and supporting devices such as a flow meter and solenoid valve, can dynamically adjust the activator injection amount based on the pH monitor reading, ensuring real-time control and precise management of reaction conditions. The mixing mechanism 8 is connected to the multi-outlet port 12 and the activator outlet 71. Its internal design incorporates a highly efficient mixing component, enabling rapid and uniform mixing of various materials and the activator, further optimizing the curing reaction conditions. This not only improves material utilization and uniformity but also reduces reprocessing and waste generation due to incomplete reactions, ultimately enhancing product quality stability and the overall economic efficiency of the production line.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
