[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: an integrated cyclone gravity separation silo, including a silo body 1, the silo body 1 is integrated by a primary cyclone 3 and a secondary cyclone 2 to form a large-volume cyclone collector silo, realizing the function of a double-stage separation mechanism, and the side and top of the primary cyclone 3 are respectively provided with an air inlet 4 and an air outlet 5, the air inlet 4 adopts high wind speed air intake, and the air outlet 5 adopts low wind speed air outlet, thereby forming the technical conditions for centrifugal separation, the silo body 1 of this structure innovatively integrates the efficient primary cyclone 2 and the secondary cyclone 3, and together constitutes a large-volume cyclone collector silo system, which not only meets the needs of large-scale production, but also realizes a more sophisticated double-stage separation mechanism, the air inlet 4 adopts high wind speed air intake and the air outlet 5 adopts low wind speed air outlet, Low wind speed outlet can effectively reduce energy consumption, conforming to the industrial trend of energy conservation and emission reduction. Secondly, it also reduces the wear and breakage of materials under high-speed movement, prolongs the service life of the equipment and protects the integrity of the powder. Furthermore, the carefully controlled wind speed optimizes the initial separation effect, ensures the effective sedimentation of larger particles, lays the foundation for the deep separation of the secondary cyclone 3, and avoids the reduction of separation efficiency caused by the re-suspension of fine particles. Finally, this design also promotes the achievement of environmental protection goals, reduces dust emissions through efficient separation, and realizes a more environmentally friendly production process. Therefore, this integrated design not only improves the efficiency and accuracy of gas-solid separation, but also takes into account the comprehensive considerations of energy efficiency, environmental protection and equipment maintenance. The two-way (left-hand and right-hand) double discharge port (can be designed according to actual conditions) The top of the spiral discharging machine 6 is provided with a large-sized feed port 7, and the diameter of the large-sized feed port 7 is larger than the outer shell diameter of the spiral discharging machine 6 with two-way (left-handed and right-handed) double discharge ports (it can be designed as a two-way multi-discharging port according to actual conditions), and corresponds to the diameter of the drop port at the bottom of the silo body 1. The large-sized feed port 7 of this structure can enhance the uniformity and processing capacity of the spiral discharging machine 6 to increase the feeding speed and reduce the risk of blockage, effectively avoid the accumulation of materials at the bottom of the silo body 1 to form a blockage such as a powder "dome", and keep the whole discharging process smooth and efficient. In addition, the performance of the spiral discharging machine 6 is accurately matched with the production capacity of the upstream mill, which means that the discharge rate is calculated and adjusted to match the mill's production per unit time. The powder quantity is coordinated to ensure the continuity and stability of the whole production process. No matter in each stage of material supply, processing or discharge, seamless connection can be achieved, avoiding production interruption or material backlog caused by mismatch of discharge efficiency, and ensuring the efficient operation of the production line. This design not only improves the overall production efficiency, but also extends the service life of the equipment, reduces the maintenance cost and downtime that may be caused by uncoordinated operation, and provides strong support for the realization of automated and efficient modern production. The lower end of the first-stage cyclone 2 is a conical structure, and the top of the first-stage cyclone 2 and the connection with the second-stage cyclone 3 are in an inclined surface structure. The conical design of the lower end of the first-stage cyclone 2 helps to gradually accelerate the airflow during the downward movement.The solid particles are more thoroughly separated from the airflow due to the increased centrifugal force and deposited at the bottom of the cone, thereby improving the efficiency and effect of primary separation. The conical design also helps to reduce airflow vortices and turbulence, allowing the airflow to smoothly transition to the next level of processing or collection area, reducing energy loss and potential material re-suspension. The inclined surface design at the connection between the primary cyclone 2 and the secondary cyclone 3 can ensure that the airflow coming out of the primary cyclone 2 can smoothly transfer to the secondary cyclone 3, avoiding direct impact to cause energy loss or reduced separation efficiency, further improving the separation performance and processing capacity of the overall system, and the first discharge port 8 is provided on both sides of the bidirectional (left-hand and right-hand) double discharge port (can be designed as a bidirectional multi-discharge port design according to actual conditions) spiral discharger 6. And the second discharge port 9, and the first discharge port 8 and the second discharge port 9 are in different directions. The spiral discharge machine 6 of this structure can convey materials in different directions through the first discharge port 8 and the second discharge port 9. This two-way double-port design can flexibly adapt to the layout of the subsequent conveying system and improve the configuration flexibility of the production line. That is, in this way, the user can flexibly arrange the destination of the material according to the needs of the actual production process, whether it is distributed to different processing links or packaging and storage areas, it can be easily achieved without making major adjustments to the original production line, thereby ensuring production continuity while optimizing space utilization and improving overall operating efficiency. The large-size feed port 7 corresponds to the position of the drop port at the bottom of the silo body 1, and the straightness of the large-size feed port 7 The diameter is larger than the outer shell diameter of the spiral discharging machine 6 with two-way (left-handed and right-handed) double discharge ports (can be designed as a two-way multi-discharging port according to actual conditions). The large-sized feed port 7 of this structure can effectively increase the flow rate of materials entering the spiral discharging machine 6, especially when processing high-yield or large-particle materials, ensuring continuous and stable material supply, avoiding the bottleneck effect caused by the narrow feed port, improving the circulation efficiency and processing capacity of the overall production line, and helping to balance the pressure inside the spiral discharging machine 6, reducing the pressure impact on the structure of the spiral discharging machine 6 at the moment of feeding, and also making the material more evenly distributed when entering the silo, avoiding local accumulation or voids, and maintaining the stable flow of materials inside the silo. The diameter of the secondary cyclone 2 is larger than that of the primary cyclone 3. The diameter of the secondary cyclone 2 is larger than that of the primary cyclone 3. The partial area is separated by steps to form a common area for the secondary cyclone and gravity sedimentation. The gravity sedimentation area includes the entire secondary cyclone 2. This structure can not only guide the airflow to smoothly transition from the primary cyclone 2 and the secondary cyclone 3, but also change the direction of the airflow to cause the gas-solid mixture to undergo another energy conversion before entering the secondary cyclone 3, which helps to enhance the vortex motion in the airflow and improve the separation efficiency, especially for those small particles that cannot be completely separated in the primary separation. At the same time, the gravity sedimentation area can further guide the airflow to move along a specific path, increase the residence time of the airflow in the equipment, improve the separation accuracy, and promote the effective sedimentation of the remaining solid particles in the airflow.The re-involvement of separated particles by the airflow is reduced, ensuring a more thorough separation effect. The top of the secondary cyclone 3 is an arched structure, and the air outlet 5 is provided with an interface connected to the return air duct. The air outlet 5 of this structure can be connected to the return air duct so that the clean gas discharged from the top of the primary cyclone 2 or the gas further purified by the secondary cyclone 3 can pass smoothly through the return air duct and be re-introduced into the system for recycling or directed to a specific processing unit. This design not only optimizes the circulation path of the airflow and improves the overall energy efficiency of the system, but also reduces the impact on the external environment through closed-loop circulation, reflecting the dual consideration of environmental protection and economy.

[0018] Working principle: When the integrated cyclone separation silo is used, the dusty gas first enters the side air inlet 4 of the primary cyclone 3. At this time, a high wind speed air intake strategy is adopted to reduce energy consumption and protect the integrity of the material. The gas is accelerated in the conical structure of the secondary cyclone 2, and the centrifugal force is used to initially separate the larger particles and make them settle to the bottom of the cone. The separated gas passes through the secondary cyclone 2 and the primary cyclone 3 to form a common area for the secondary cyclone and gravity sedimentation. The airflow direction is changed on the way, the vortex motion is enhanced, and the separation efficiency is improved. Inside the secondary cyclone 2, The gas refinement and separation process ensures the complete separation of fine particles until the clean gas is finally discharged from the arched top air outlet 5 of the first-stage cyclone 3. The air outlet 5 uses a low wind speed to discharge air, which can be connected to the return air duct through an interface for recycling. At the same time, the large-size feed port 7 continuously feeds the spiral discharging machine 6 evenly and efficiently to avoid blockage at the bottom of the silo body 1. The spiral discharging machine 6 then flexibly distributes the material flow through the first discharge port 8 and the second discharge port 9 to ensure the continuous and stable production process and complete the entire gas-solid separation process, thereby completing a series of tasks.
