A cone-shaped vibration high-efficiency unloading device

Abstract

This application provides a conical vibrating high-efficiency unloading device, relating to the field of dust unloading technology. It includes a conical hopper, a stirring mechanism, and a vibration mechanism. The conical hopper has an inlet at its top and an outlet and valve at its bottom, with an anti-stick coating sprayed on its inner wall. The stirring mechanism includes a stirring motor installed at the top of the conical hopper, a stirring shaft extending into the hopper, and staggered stirring blades. The vibration mechanism is installed on the outside of the conical hopper to disperse the material. This application, by designing the hopper as a cone shape and incorporating both the stirring and vibration mechanisms, and by spraying an anti-stick coating on the inner wall of the hopper, utilizes the reduced bottom structure of the conical hopper to promote the natural sliding of material using gravity, reducing residue. The stirring mechanism breaks up bridging phenomena through stirring and works synergistically with the vibration mechanism to achieve dual anti-clogging. This application, by integrating the conical structure, anti-stick coating, stirring, and vibration functions, ensures a smooth powder unloading process.

Description

Technical Field

[0001] This application relates to the field of dust unloading technology, and more specifically, to a cone-shaped vibration high-efficiency unloading device. Background Technology

[0002] In the smelting process of antimony-containing minerals (such as stibnite), volatilization roasting is one of the core steps in antimony extraction. This process controls the roasting temperature to cause antimony to volatilize into the flue gas in the form of antimony trioxide (Sb2O3), and then collects and recovers the Sb2O3 through a flue gas dust collection system.

[0003] However, in existing technologies, the collected Sb2O3 dust is stored in traditional square storage silos. However, since the particle size of the powder is generally less than 10μm, which falls into the category of ultrafine particles, its high specific surface area leads to a significant increase in interparticle forces. At the same time, the powder often contains high levels of arsenic (As) impurities. During storage, the powder is very prone to adhesion, bridging, and blockage in the silo, resulting in a silo emptying rate of only 75%–85%. This causes material residue and resource waste. Furthermore, bridging occurs frequently, requiring manual intervention 3–5 times per day to restore material flow. The blockage problem seriously restricts the stable operation of the smelting system and increases the risk of unplanned shutdowns.

[0004] In view of this, this application proposes a conical vibration high-efficiency unloading device, which effectively solves the above-mentioned technical problems by optimizing the structure of the storage bin. Summary of the Invention

[0005] The purpose of this application is to provide a cone-shaped vibration high-efficiency unloading device, which can solve the technical problem of easy adhesion and blockage of powder unloading.

[0006] This application provides a cone-shaped vibrating high-efficiency unloading device, including a cone-shaped hopper, a stirring mechanism, and a vibration mechanism;

[0007] The cone-shaped hopper has a feed inlet at the top and a discharge outlet and valve at the bottom, and its inner wall is coated with an anti-stick coating.

[0008] The mixing mechanism includes a mixing motor installed at the top of the conical silo, a mixing shaft extending into the silo, and interleaved mixing blades;

[0009] The vibration mechanism is installed on the outside of the conical silo and is used to disperse the material.

[0010] Furthermore, the stirring blades are provided in multiple ways, and the multiple stirring blades are arranged perpendicularly and alternately on the stirring shaft.

[0011] Furthermore, the length of the plurality of stirring blades gradually decreases from top to bottom to match the conical hopper.

[0012] Furthermore, the conical hopper is provided with an inclined groove at the location of the feed inlet, and the opening of the inclined groove serves as the feed inlet.

[0013] Furthermore, the inclined slot opening is provided with an opening and closing cover, which is connected to the top of the conical hopper via a hinge structure, and the opening and closing cover is provided with a handle.

[0014] Furthermore, the vibration mechanism is equipped with a drive motor and an eccentric wheel structure. The drive motor is installed in the middle of the outer side of the conical hopper, and the eccentric wheel structure is set in close contact with the outer wall of the conical hopper and connected to the drive motor, so that the vibration is caused by the drive motor rotating the eccentric wheel structure to disperse the material.

[0015] Furthermore, the valve at the discharge port is a manual gate valve, which is connected to the conical hopper via a flange.

[0016] The beneficial effects of this utility model are:

[0017] This utility model provides a conical vibrating high-efficiency unloading device, including a conical hopper, a stirring mechanism, and a vibration mechanism. The top of the conical hopper has a feed inlet, the bottom has a discharge outlet and a valve, and the inner wall is coated with an anti-stick coating. The stirring mechanism includes a stirring motor installed at the top of the conical hopper, a stirring shaft extending into the hopper, and staggered stirring blades. The vibration mechanism is installed on the outside of the conical hopper to disperse the material. This utility model has a simple structure and reasonable design. By making the hopper conical and setting up a stirring and vibration mechanism, and by spraying an anti-stick coating on the inner wall of the hopper, the tapered structure at the bottom of the conical hopper can use gravity to promote the natural sliding of the material, reducing residue. The stirring mechanism breaks up bridging by stirring and works in conjunction with the vibration mechanism to achieve double anti-blocking. This application ensures smooth unloading of powder by integrating the conical structure, the anti-stick coating, and the stirring and vibration functions. Attached Figure Description

[0030] See Figures 1-3 As shown, the conical vibration high-efficiency unloading device provided in this embodiment includes a conical hopper 1, a stirring mechanism 2, and a vibration mechanism 3;

[0031] The cone-shaped hopper 1 is provided with a feed inlet 11 at the top and a discharge outlet 12 and a valve 13 at the bottom, and its inner wall is coated with an anti-stick coating.

[0032] The stirring mechanism 2 includes a stirring motor 21 installed at the top of the conical silo 1, a stirring shaft 22 extending into the silo, and staggered stirring blades 23;

[0033] The vibration mechanism 3 is installed on the outside of the conical silo 1 and is used to disperse the material.

[0034] This embodiment has a simple structure and reasonable design. By setting the hopper to a cone shape and setting a stirring mechanism 2 and a vibration mechanism 3, and spraying an anti-stick coating on the inner wall of the hopper, the tapered structure at the bottom of the cone-shaped hopper 1 can use gravity to promote the natural sliding of materials and reduce residue. The stirring mechanism 2 breaks up the bridging phenomenon through stirring and works in synergy with the vibration mechanism 3 to achieve double anti-clogging. This embodiment ensures a smooth powder unloading process by integrating the cone structure, anti-stick coating, stirring and vibration functions.

[0035] In some embodiments, multiple stirring blades 23 are provided, and the multiple stirring blades 23 are arranged perpendicularly and alternately on the stirring shaft 22.

[0036] Specifically, the length of the plurality of stirring blades 23 gradually decreases from top to bottom to match the conical hopper 1.

[0037] In this embodiment, multiple stirring blades 23 are arranged vertically and alternately on the stirring shaft 22, forming intersections in both the axial and radial directions. This can prevent local material accumulation and ensure the stirring effect. At the same time, the length of the stirring blades 23 gradually decreases from top to bottom, matching the setting of the conical hopper 1. This can ensure that blades can also be set at the bottom of the conical hopper 1 for stirring, thereby improving the overall stirring efficiency and stirring effect.

[0038] In some embodiments, the conical hopper 1 is positioned at the location of the feed inlet 11 and is provided with an inclined groove 14, the opening of which serves as the feed inlet 11.

[0039] Specifically, the opening of the inclined groove 14 is provided with an opening and closing cover 15, which is connected to the top of the conical hopper 1 through a hinge structure 16, and the opening and closing cover 15 is provided with a handle 17.

[0040] In this embodiment, a slanted feed groove is provided, which makes feeding smooth and convenient. The opening and closing cover 15 can be closed when the machine is stopped to avoid contamination and ensure safety during use.

[0041] In some embodiments, the vibration mechanism 3 is provided with a drive motor 31 and an eccentric wheel structure 32. The drive motor 31 is installed on the outer middle of the conical hopper 1, and the eccentric wheel structure 32 is set against the outer wall of the conical hopper 1 and connected to the drive motor 31, so that the drive motor 31 drives the eccentric wheel structure 32 to rotate and cause vibration, thereby dispersing the material.

[0042] In this embodiment, the eccentric wheel is driven by the drive motor 31 to rotate, generating centrifugal force, which causes high-frequency low-amplitude vibration of the hopper, effectively breaking the material bridging and allowing the material to be discharged smoothly.

[0043] In some embodiments, the valve 13 at the discharge port 12 is a manual gate valve, which is connected to the conical hopper 1 via a flange.

[0044] In this embodiment, the manual gate valve does not require electrical control and can be used flexibly based on unloading requirements, making it highly practical.

[0045] The above are merely preferred embodiments of this application and are 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.
