Description

Technical Field

[0001] This utility model belongs to the field of material storage technology, specifically relating to a lime powder storage bin with anti-caking and stirring function. Background Technology

[0002] Preventing clumping is crucial for ensuring smooth discharge of lime powder during storage. However, most existing storage silos employ a bottom conical discharge structure, relying on the gravity of the lime powder for discharge. As the material naturally accumulates under gravity, the powder at the bottom and lower middle parts of the silo experiences significant pressure, making it prone to clumping. These clumps of lime powder tend to accumulate at the bottom of the cone, causing blockages in the discharge channel.

[0003] To alleviate the clumping problem, some existing storage silos are equipped with vibration devices on the outside of the silo walls or simple stirring rods inside. However, these structures have significant limitations: the vibration devices can only act on materials near the silo walls, having limited impact on lime powder in the central area of ​​the silo, and long-term high-frequency vibration may cause fatigue cracking of the silo structure; the simple stirring rods are mostly fixed single-shaft structures with a limited stirring range, making it difficult to effectively break up large clumps of material. Therefore, a lime powder storage silo with anti-caking stirring function is needed to meet the requirements of efficient discharge and stable operation of lime powder storage silos. Utility Model Content

[0004] To overcome the limitations of existing storage silos that use vibration devices or simple stirring rods, this invention provides a lime powder storage silo with an anti-caking stirring function. By incorporating a stirring mechanism and a vibration mechanism within the silo, comprehensive anti-caking treatment of the material inside is achieved. The vibration motor drives the vibrating plate to generate regular vibration force, which is transmitted to all areas inside the silo via the vibrating rod. Simultaneously, the stirring rod and blades of the stirring mechanism expand the stirring range, effectively solving the problem of material agglomeration near the silo wall and in the central area. This effectively avoids the limitations of traditional single vibration devices or simple stirring rods, significantly improving the anti-caking effect and discharge efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A lime powder storage silo with anti-caking stirring function mainly includes a silo body, a stirring mechanism, a vibration mechanism, a discharge assembly, and a support frame. The silo body is a cylindrical structure with a conical bottom and a discharge port. A discharge valve is installed at the discharge port. An inlet is provided at the top of the silo body, and a detachable sealing cover is installed at the inlet. The support frame is fixedly installed outside the silo body, and the stirring mechanism is installed inside the silo body, with a discharge assembly installed at its bottom. The vibration mechanism includes a vibrating plate, a vibrating motor, a vibrating rod, and a spring. The vibrating plate is installed on the outer wall of the top of the silo body via the spring. The vibrating motor is fixedly installed on the upper surface of the vibrating plate and electrically connected to the controller. The vibrating rods are evenly distributed along the circumference of the silo body, with the top end penetrating the top wall of the silo body and fixedly connected to the vibrating plate, and the bottom end extending into the silo body near the top of the conical shape. The spring is sleeved on the vibrating rod, with the bottom end fixedly connected to the outer wall of the top of the silo body and the top end fixedly connected to the bottom of the vibrating plate.

[0006] The stirring mechanism includes a rotating shaft, stirring rods, a motor, and stirring blades. The motor is installed on the top of the chamber and electrically connected to the controller. The rotating shaft is vertically installed at the center of the chamber, with its top end penetrating the top wall of the chamber and connected to the motor via a coupling. Its bottom end extends to the end of the chamber and is fixedly connected via a bearing. The stirring rods consist of multiple rods evenly distributed radially along the rotating shaft. Each stirring rod is connected to the rotating shaft by bolts. Stirring blades are installed at both ends of the stirring rods. The stirring blades have a spiral structure and wavy grooves on their surface. The groove depth is 2mm to 4mm, and the wavy grooves are evenly distributed along the length of the stirring blades.

[0007] The vibrating rod is provided with multiple protruding turbulence blocks at equal intervals along the axial direction.

[0008] The discharge assembly includes a connecting block and crushing blades. The connecting block is bolted to the bottom of the rotating shaft, and crushing blades with an inclination angle of 15° to 30° are evenly installed on the connecting block along the circumferential direction.

[0009] The beneficial effects of this utility model are:

[0010] This invention solves the shortcomings of traditional lime powder storage silos in terms of anti-caking and discharge by combining the synergistic action of the stirring mechanism and the vibration mechanism with the pneumatic discharge function of the discharge component. The stirring rod and stirring blade of the stirring mechanism expand the stirring range, and the vibration mechanism transmits the vibration force to all areas inside the silo through the vibrating rod. The two work together to effectively prevent the material from caking on the inner wall and central area of ​​the silo, and significantly improve the anti-caking effect and discharge efficiency.

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] This utility model discloses a lime powder storage silo with anti-caking stirring function. The lime powder storage silo with anti-caking stirring function mainly includes a silo body 1, a stirring mechanism 2, a vibration mechanism 3, a discharge assembly 4, and a support frame 5. The silo body 1 is a cylindrical structure with a conical bottom and a discharge port 101. A discharge valve is installed at the discharge port 101 to adjust the discharge speed. The top of the silo body 1 is provided with a feed inlet 104, and a detachable sealing cover 105 is installed at the feed inlet 104. The sealing cover 105 is connected to the top of the silo body 1 through a flange, and a rubber sealing ring is provided on the inner side to prevent external dust from entering the interior of the silo body 1. The support frame 5 is fixedly installed on the outside of the silo body 1 to enhance the overall stability of the silo body 1.

[0018] The stirring mechanism 2 is installed inside the chamber 1 and includes a rotating shaft 201, stirring rods 202, a motor 203, and stirring blades 204. The motor 203 is installed on the top of the chamber 1 and electrically connected to the controller. The rotating shaft 201 is vertically installed at the center of the chamber 1, with its top end penetrating the top wall of the chamber 1 and connected to the output shaft of the motor 203 via a coupling. Its bottom end extends to the conical bottom of the chamber 1 and is fixedly connected by a bearing. There are multiple stirring rods 202, which are evenly distributed radially along the rotating shaft 201. Each stirring rod 202 is bolted to the rotating shaft 201. Stirring blades 204 are installed at both ends of the stirring rods 202. The stirring blades 204 are spiral in shape with a spiral angle of 30° to 45° and have wavy grooves on their surface with a groove depth of 2mm to 4mm. The wavy grooves are evenly distributed along the length of the stirring blades 204. The rotation direction of the stirring blade 204 is the same as that of the rotating shaft 201. The rotation of the rotating shaft 201 and the stirring rod 202 drives the stirring blade 204 to turn the material in the bin 1 in all directions, which can cover the central area and the edge area of ​​the bin 1.

[0019] Vibration mechanism 3 includes a vibrating plate 301, a vibrating motor 302, a vibrating rod 303, and a spring 304. The vibrating plate 301 is a circular steel plate with a diameter slightly smaller than the diameter of the top outer wall of the silo body 1. It is mounted on the top outer wall of the silo body 1 via the spring 304. The spring 304 is sleeved on the vibrating rod 303, with its bottom end fixedly connected to the top outer wall of the silo body 1 and its top end fixedly connected to the bottom of the vibrating plate 301. The vibrating motor 302 is mounted on the upper surface of the vibrating plate 301 and electrically connected to the controller. The eccentric force generated by the vibrating motor 302 during operation causes the vibrating plate 301 to vibrate. 01 generates reciprocating vibration. The vibrating rod 303 is a cylindrical metal rod, evenly distributed along the circumference of the silo body 1, with a quantity of no less than six. The top of each vibrating rod 303 is fixedly connected to the vibrating plate 301 by a threaded connection, and the bottom extends into the silo body 1 near the top of the cone. The length of the vibrating rod 303 is set according to the height of the silo body 1 to ensure that the vibration energy can cover all areas inside the silo body 1. The vibrating rod 303 is provided with multiple protruding turbulence blocks 3031 at equal intervals along the axial direction to further enhance the crushing effect of agglomerated lime powder.

[0020] The discharge assembly 4 includes a connecting block 401 and a crushing blade 402. The connecting block 401 is bolted to the bottom of the rotating shaft. The crushing blade 402 is evenly installed on the connecting block 401 along the circumferential direction. The crushing blade 402 is used to perform secondary crushing of the agglomerates and can accelerate the discharge of materials.

[0021] In actual operation, the controller periodically starts the motor 203, which drives the rotating shaft 201 to rotate. The rotating shaft 201 drives the stirring rod 202 to rotate synchronously, and the stirring blades 204 tumble the material in the bin 1. The wavy grooves increase the contact area between the stirring blades 204 and the material. The spiral angle setting causes the stirring blades 204 to generate axial thrust during rotation, promoting the up-and-down circulation of the material. At the same time, the vibration motor 302 starts, and the output shaft drives the vibrating plate 301 to generate up-and-down reciprocating vibration. The vibration energy is transmitted to various areas inside the bin 1 through the vibrating rod 303. The turbulence blocks 3031 set on the vibrating rod 303 apply a disturbance to the material, preventing the material from forming lumps on the inner wall and central area of ​​the bin 1. When discharge is required, the discharge valve is opened. At the same time, the stirring action of the crushing blades 402 pushes the lime powder to be quickly discharged through the discharge port 101. In order to enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with specific application scenarios.

[0022] First, during the feeding stage of the lime powder storage silo, the operator injects lime powder into the silo body 1 through the feed inlet 104. After the sealing cover 105 is closed, the rubber sealing ring on its inner side fits tightly against the top of the silo body 1 to prevent external dust from entering the silo body 1 and ensure the purity of the material.

[0023] During material storage, the vibration mechanism 3 and the stirring mechanism 2 are controlled periodically by the controller. When the motor 203 starts, the rotating shaft 201 begins to rotate under its drive. The bolts on the rotating shaft 201 drive multiple stirring rods 202 to rotate synchronously. The stirring blades 204 installed at both ends of the stirring rods 202 rotate accordingly. During rotation, they not only increase the contact area with the material but also generate axial thrust inside the silo 1, causing the material to circulate vertically within the silo 1, preventing clumping caused by long-term static storage. Simultaneously, the wavy grooves further enhance the crushing effect of the stirring blades 204 on the material. After the vibration motor 302 starts, the eccentric force generated by its output shaft causes the vibrating plate 301 to vibrate vertically. The vibrating plate 301 is connected to the top outer wall of the silo 1 via springs 304. The elastic characteristics of the springs 304 effectively absorb the impact force in the vibration energy, preventing structural fatigue or cracking of the silo 1 due to long-term vibration. The vibration of the vibrating plate 301 is transmitted to various areas inside the silo 1 through the vibrating rod 303. The turbulence block 3031 of the vibrating rod 303 agitates the material, further enhancing the dispersion effect and effectively preventing the material from forming clumps on the inner wall and central area of ​​the silo 1. The vibrating rod 303 is evenly distributed along the circumference of the silo 1, ensuring that the vibration energy can cover all areas inside the silo 1, avoiding the limitation of traditional single vibration devices that can only act on materials near the silo wall.

[0024] When material needs to be discharged, the discharge valve opens and the lime powder is discharged through the discharge port 101. At this time, the motor 203 is started, and the motor 203 drives the rotating shaft 201 to rotate, which in turn drives the crushing blade 402 to rotate, applying an oblique thrust to the material, thereby accelerating the material discharge and ensuring the continuity and efficiency of the discharge process.

[0025] The mixing mechanism 2 and the vibration mechanism 3 process the material from the inside and outside, respectively. Their combined action achieves comprehensive anti-caking treatment of the material within the silo 1. The mixing mechanism 2 expands the mixing range through the mixing shaft and mixing blades, while the vibration mechanism 3 transmits vibration energy to all areas inside the silo 1 through the vibrating rod 303, overcoming the limitations of traditional single vibration devices or simple mixing rods. The crushing blade 402 in the discharge assembly 4 further improves the discharge efficiency.

Electrical control components not mentioned in this technical solution are existing technologies and are not shown in the figures, nor will they be described further.

[0027] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
