Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Example 1

[0028] A powder feeding device for preventing blockage includes a feeding mechanism and an infeed mechanism disposed below the end of the feeding mechanism.

[0029] The feeding mechanism can intermittently feed materials into the feeding mechanism;

[0030] The feeding mechanism includes a feeding cylinder 5 and a conveying cylinder 9 disposed at the bottom of the feeding cylinder 5 and communicating with the feeding cylinder 5.

[0031] The feeding cylinder 5 is equipped with a dispersion component for dispersing powder.

[0032] A screw conveyor is installed inside the conveying cylinder 9, and a discharge port 12 is provided at the end of the conveying cylinder 9.

[0033] Working Principle: In use, the powder is fed to the feeding mechanism, which can intermittently feed the powder into the infeeding mechanism. This allows the infeeding mechanism to sequentially feed the received powder, creating initial anti-clogging. Specifically, the powder is fed into the feeding cylinder 5 and further dispersed by the dispersing component, allowing for smoother transport. The dispersed powder then enters the conveying cylinder 9 and is conveyed forward by the screw conveyor, exiting through the discharge port 12 and delivered to the reaction equipment. During the conveying process within the screw conveyor, any powder that may clump can be further crushed, ensuring effective powder feeding and enabling more efficient reaction after the powder enters the reaction equipment.

[0034] In this embodiment, the feeding mechanism includes a conveyor belt mechanism 1. Baffles 2 are respectively provided on both sides of the conveyor belt mechanism 1, and multiple partition plates 3 are provided between a pair of baffles 2. The multiple partition plates 3 divide the surface of the conveyor belt mechanism 1 into multiple independent storage cavities 31. In this way, when the powder raw material is fed to the conveyor belt mechanism 1, as the conveyor belt mechanism 1 rotates, the powder can be dispersed in different storage cavities 31 in sequence, so that the powder is divided into multiple parts and fed into the feeding cylinder 5 in sequence and intermittently, avoiding the problem of powder material easily agglomerating and causing blockage when feeding in a concentrated manner.

[0035] In this embodiment, the feeding cylinder 5 is a spherical cylinder, and the top of the feeding cylinder 5 is provided with a funnel-shaped open receiving port 4, and the bottom of the feeding cylinder 5 is provided with a feeding port, which is connected to the conveying cylinder 9; this facilitates the use of the receiving port 4 to receive the powder material conveyed by the feeding mechanism, and the powder material can be smoothly delivered into the feeding cylinder 5.

[0036] In this embodiment, the dispersing component includes a rotating shaft 8 arranged laterally within the feeding cylinder 5. One end of the rotating shaft 8 is connected to a motor. Multiple material blocking plates 6 are arranged circumferentially on the rotating shaft 8, and the material blocking plates 6 extend along the length of the rotating shaft 8. The multiple material blocking plates 6 divide the interior of the feeding cylinder 5 into multiple independent dispersing cavities. In this way, after the powder enters the feeding cylinder 5, it can be dispersed sequentially in the dispersing cavities between the multiple material blocking plates 6 under the rotation of the rotating shaft 8, and then sequentially dispersed and fed into the conveying cylinder 9 within the feeding cylinder 5, so that the material can be conveyed in an orderly manner.

[0037] In this embodiment, an arc-shaped scraper 7 is provided at the end of the material blocking plate 6. The end of the arc-shaped scraper 7 can abut against the inner wall of the feeding cylinder 5, and the arc of the arc-shaped scraper 7 is the same as the arc of the feeding cylinder 5. In this way, during the rotation of the material blocking plate 6, the arc-shaped scraper 7 can be used to scrape off the powder material that may adhere to the inner wall of the feeding cylinder 5, so as to avoid excessive powder adhering to the inner wall of the feeding cylinder 5 and reduce material waste.

[0038] In this embodiment, the screw conveyor includes a conveying shaft 11 and a plurality of screw conveying blades 10 disposed on the conveying shaft 11. Along the conveying direction, the diameter of the plurality of screw conveying blades 10 gradually decreases. The front end of the conveying uses larger diameter screw conveying blades 10 to convey the material out of the vicinity of the feed port more quickly, avoiding the accumulation of powder near the feed port and at the front end of the screw conveyor. Subsequently, the gradually decreasing diameter of the screw conveying blades 10 helps to improve the flow state of the material, reduce blockage and overflow, and can better adapt to the flowability of powder materials, reduce adhesion and ensure smooth conveying.

[0039] In this embodiment, the spiral conveyor blade 10 is provided with a plurality of material passage holes 101, which can reduce the conveying pressure and allow the powder to pass through and disperse to different degrees within the spiral conveyor.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
