AI Technical Summary
Existing calcium carbonate storage silos are prone to blockage during unloading, especially ultrafine heavy calcium carbonate and activated ultrafine heavy calcium carbonate materials. Due to their small particle size, high surface energy, and strong interparticle cohesion, it is difficult to overcome adhesion and friction, resulting in poor unloading. Furthermore, there is a lack of efficient unloading auxiliary measures, which affects production efficiency and safety.
Design a vibration-assisted unloading mechanism, including a drive motor, a rotary disk, a connecting rod, a reciprocating rod, and a clearing rod. The rotary disk drives the movement of the connecting rod and the reciprocating rod, which, combined with the high-frequency vibration generated by the vibration motor at the unloading port, breaks down the agglomerated structure and weakens the adhesion between the material and the silo wall. The clearing rod, in conjunction with the mechanism, mechanically clears the material, ensuring smooth discharge.
It effectively avoids bridging and rat hole blockage, improves unloading efficiency, ensures the continuity of the production process, reduces manual intervention, lowers safety risks, and meets the needs of industrial production.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcium carbonate storage silos, and in particular to a calcium carbonate storage silo with a vibration-assisted unloading mechanism. Background Technology
[0002] A storage silo is a closed container or structure used for centralized storage of solid bulk materials (such as powdery, granular, or lumpy raw materials). It is usually made of metal (such as carbon steel or stainless steel) or concrete. Its design structure includes core components such as the silo body, inlet, outlet, ventilation device, and monitoring system. Material storage and supply are achieved through gravity unloading or mechanical conveying. Its function is similar to a large "storage tank". It can effectively prevent materials from getting damp, dust pollution, and external impurities from mixing in. It is widely used in industries such as building materials (such as cement and sand), chemicals (such as plastic granules), food (such as flour and sugar powder), and mining (such as ore powder). It is a key piece of equipment in industrial production to ensure continuous supply of raw materials, optimize the utilization of storage space, and realize automated production.
[0003] In existing technologies, when producing new non-metallic mineral materials such as ultrafine heavy calcium carbonate and activated ultrafine heavy calcium carbonate, calcium carbonate storage silos are mainly used to temporarily store semi-finished or finished materials during processing, ensuring the continuity and stability of the production process. These materials typically have characteristics such as fine particle size, large specific surface area, and easy moisture absorption and agglomeration. Storage silos can provide a closed and stable storage environment to prevent the materials from becoming damp, deteriorating, or being contaminated by external factors.
[0004] However, existing calcium carbonate storage silos have significant drawbacks in practical use. Materials like ultrafine heavy calcium carbonate and activated ultrafine heavy calcium carbonate, due to their small particle size, high surface energy, and extremely strong interparticle cohesion, are difficult to overcome with gravity alone during unloading. This leads to bridging, rodent holes, and other blockages within the silo. Furthermore, the lack of efficient and targeted unloading aids means that once blockages occur, the material's flowability decreases drastically. Existing simple vibration devices or stirring structures are insufficient to penetrate the material and break up agglomerates, making it impossible to effectively solve the unloading problem. In this situation, operators must frequently intervene manually to clear the blockage, which not only significantly increases labor costs but also introduces safety risks such as working at heights and dust inhalation, seriously affecting the health of operators. In addition, the stagnation during unloading and the time consumed by manual intervention significantly reduce overall unloading and production efficiency, making it difficult to meet the high-efficiency requirements of large-scale, continuous industrial production. Utility Model Content
[0005] The main objective of this invention is to provide a calcium carbonate storage silo with a vibration-assisted unloading mechanism, which can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A calcium carbonate storage silo with a vibration-assisted unloading mechanism includes a support frame. The calcium carbonate storage silo body is fixedly connected inside the support frame. An inlet is fixedly installed on the top surface of the calcium carbonate storage silo body, and a discharge port is fixedly installed on the bottom surface of the calcium carbonate storage silo body. A discharge valve is fixedly installed on the top surface of the discharge port. The calcium carbonate storage silo body is equipped with a vibration unloading mechanism, which includes a support base, a rotating disk, a drive motor, a connecting rod, a reciprocating rod, and a unblocking rod. Symmetrical support bases are fixedly connected to the top surface of the calcium carbonate storage silo body. Two rotating disks are movably connected to the support bases via rotating rods on their outer side walls. The drive motor is fixedly connected to the outer side wall of the support base, and its output end is fixedly connected to the rotating rod. The reciprocating rod is movably connected inside the calcium carbonate storage silo body and movably connected to the rotating disk via a connecting rod. A unblocking rod is also fixedly connected to the outer wall of the reciprocating rod.
[0008] In a preferred embodiment, a set of symmetrical vibration motors are fixedly installed on the outer wall of the inclined portion of the discharge port.
[0009] In a preferred embodiment, a guide hole is provided on the top surface of the calcium carbonate storage silo body.
[0010] In a preferred embodiment, a set of symmetrical support seats are fixedly installed on the top surface of the calcium carbonate storage silo body, and mounting holes are provided on the side walls of the support seats, with bearings fixedly installed in the mounting holes.
[0011] In a preferred embodiment, the rotating disks are arranged in a symmetrical group, and a rotating rod is fixedly installed on the outer side wall of the rotating disk. The rotating rod is fixedly installed together with the bearing. The rotating disk is located on the inner side wall of the support base, and a first rotating shaft is fixedly installed on the inner side wall of the rotating disk. The drive motor is fixedly installed on the outer side wall of one of the support bases, and the output end of the drive motor is fixedly installed together with the rotating rod.
[0012] In a preferred embodiment, the connecting rods are provided in a symmetrical set, and a first rotating hole and a second rotating hole are respectively opened on the upper and lower sides of the side wall of the connecting rods, and the first rotating shaft is movably installed in the first rotating hole.
[0013] In a preferred embodiment, the reciprocating rod is inserted into the guide hole, and a set of symmetrical second rotating shafts are fixedly installed on the outer wall of the top end of the reciprocating rod. The second rotating shafts are movably installed in the second rotating hole. Several downwardly inclined unblocking rods are also fixedly installed on the outer wall of the reciprocating rod at the discharge port.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] In this invention, the vibration unloading mechanism consists of a drive motor, a rotating disk, a connecting rod, a reciprocating rod, and a clearing rod. The drive motor drives the rotating disk to rotate, and the connecting rod causes the reciprocating rod to perform reciprocating linear motion within the guide hole. This, in turn, drives the clearing rod to mechanically clear the material near the unloading port. It can penetrate deep into the material, effectively breaking down the agglomerated structure and preventing bridging, rat holes, and other blockages. Simultaneously, the vibration motors symmetrically installed on the outer wall of the inclined part of the unloading port can generate high-frequency vibration force and transmit it to the silo wall, weakening the adhesion between the material and the silo wall, causing the material hanging on the wall to fall off. This works in synergy with the internal clearing device, greatly improving unloading efficiency, ensuring smooth material discharge, maintaining the continuity of the production process, reducing manual clearing, lowering costs and safety risks, optimizing material flow, reducing residue, and having strong applicability to meet the needs of industrial production. Thus, the calcium carbonate storage silo body has an anti-clogging vibration-assisted unloading function. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-4 As shown, a calcium carbonate storage silo with a vibration-assisted unloading mechanism includes a support frame 1. A calcium carbonate storage silo body 2 is fixedly connected inside the support frame 1. An inlet 3 is fixedly installed on the top surface of the calcium carbonate storage silo body 2, and a discharge port 4 is fixedly installed on the bottom surface of the calcium carbonate storage silo body 2. A discharge valve 5 is fixedly installed on the top surface of the discharge port 4. A vibration unloading mechanism 6 is provided inside the calcium carbonate storage silo body 2. The vibration unloading mechanism 6 includes a support base 9, a rotating disk 12, a drive motor 15, a connecting rod 16, and a reciprocating... The top surface of the calcium carbonate storage silo body 2 is fixedly connected to symmetrical support seats 9, and two rotating disks 12 are movably connected to the support seats 9 through rotating rods 13 on the outer side walls. The drive motor 15 is fixedly connected to the outer side wall of the support seat 9, and the output end of the drive motor 15 is fixedly connected to the rotating rod 13. The reciprocating rod 19 is movably connected inside the calcium carbonate storage silo body 2 and is movably connected to the rotating disks 12 through connecting rods 16. The outer wall of the reciprocating rod 19 is also fixedly connected to the unblocking rod 21.
[0023] Example 1:
[0024] like Figure 2 As shown, a set of symmetrical vibration motors 7 are fixedly installed on the outer wall of the inclined part of the discharge port 4. After being powered on, the vibration motors 7 rotate at high speed through the internal eccentric block, generating centrifugal force to form high-frequency vibration. This vibration force acts directly on the wall of the discharge port 4 and is transmitted to the surrounding area, causing the calcium carbonate material attached to the wall to lose its adhesion and fall off due to vibration. At the same time, it destroys the internal agglomeration structure of the material, avoiding the formation of bridging, rat holes and other blockages at the discharge port. It can effectively reduce the material residue on the wall, ensure smooth material flow in the area of the discharge port 4, and enable the material to converge more efficiently to the discharge port 4, laying the foundation for the discharge process.
[0025] Example 2:
[0026] like Figures 2-4As shown, the top surface of the calcium carbonate storage silo body 2 is provided with guide holes 8. A set of symmetrical support seats 9 are also fixedly installed on the top surface of the calcium carbonate storage silo body 2, and mounting holes 10 are provided on the side walls of the support seats 9. Bearings 11 are fixedly installed in the holes of the mounting holes 10. A set of symmetrical rotating disks 12 are provided, and rotating rods 13 are fixedly installed on the outer side walls of the rotating disks 12. The rotating rods 13 and bearings 11 are inserted and fixedly installed together. The rotating disks 12 are located on the inner side walls of the support seats 9, and a first rotating shaft 14 is fixedly installed on the inner side walls of the rotating disks 12. A drive motor 15 is fixedly installed on one of the support seats. On the outer wall of 9, the output end of the drive motor 15 is fixedly installed together with the rotating rod 13; the connecting rod 16 is provided with a symmetrical set, and the upper and lower sides of the side wall of the connecting rod 16 are respectively provided with a first rotating hole 17 and a second rotating hole 18, and the first rotating shaft 14 is movably installed in the first rotating hole 17; the reciprocating rod 19 is inserted into the guide hole 8, and a set of symmetrical second rotating shafts 20 is fixedly installed on the outer wall of the top end of the reciprocating rod 19. The second rotating shafts 20 are movably installed in the second rotating hole 18. Several downwardly inclined unblocking rods 21 are also fixedly installed on the outer wall of the reciprocating rod 19 and at the discharge port 4;
[0027] The specific operating principle of the vibration unloading mechanism 6 in conjunction with the calcium carbonate storage silo body 2 is as follows:
[0028] When the calcium carbonate storage silo body 2 begins to unload, the drive motor 15 is powered on, and the internal electromagnetic system drives the rotor to rotate at high speed. Its output end stably transmits the rotational power to the rotating rod 13. The rotating rod 13 passes through the bearing 11 installed in the mounting hole 10 on the side wall of the support base 9. The ball structure of the bearing 11 greatly reduces the friction loss during rotation, thereby driving the rotating disk 12 to make a stable circular motion on the inner side wall of the support base 9. The first rotating shaft 14 on the inner side wall of the rotating disk 12 moves in a circular motion with the disk body. Through the connection with the movable rod of the first rotating hole 17 above the connecting rod 16, the rotational motion is converted into the swing of the connecting rod 16. The second rotating hole 18 below the connecting rod 16 is movably connected to the second rotating shaft 20 at the top of the reciprocating rod 19. At the same time, the guide hole 8 plays a precise limiting and guiding role for the reciprocating rod 19, so that when the connecting rod 16 swings, the reciprocating rod 19 performs a precise and controllable linear reciprocating motion in the guide hole 8. The unblocking rod 21, located on the outer wall of the reciprocating rod 19 and positioned downwards at the discharge port 4, is inserted into the material pile near the discharge port 4 at high frequency. Each time it is inserted, the inclined surface of the unblocking rod 21 exerts an oblique pushing force on the material, forcibly breaking up the clumps. During the return stroke, the friction between the rod surface and the material further disrupts the clump structure and pushes the loose material toward the discharge port 4. When the discharge valve 5 is opened, the physical thrust generated by the continuous mechanical movement of the internal unblocking rod 21, combined with the resonance effect of the material particles caused by the vibration waves of the external vibrating motor 7, causes the material to flow in a spiral shape toward the discharge port 4. Finally, it is smoothly discharged through the discharge valve 5, thereby greatly improving the unloading efficiency, ensuring smooth material discharge, maintaining the continuity of the production process, reducing manual unblocking, lowering costs and safety risks, optimizing material flow, reducing residue, and making it highly applicable to meet the needs of industrial production.
