Description

Technical Field

[0001] This utility model relates to the field of material conveying and storage equipment technology, and in particular to a novel vibrating discharge device for silos. Background Technology

[0002] In industries such as chemical, building materials, grain and mining, silos or bins are key equipment widely used for storing powdery, granular and other bulk materials. However, due to the inherent internal friction, deliquescence, electrical charge or irregular shape of the materials, during storage and discharge, the materials are very prone to arching or adhering to the bin wall in the conical part at the bottom of the silo, causing blockage of the discharge port and affecting the continuity and stability of production.

[0003] To address this issue, the commonly used technical solution is to install a silo wall vibrator on the outer wall of the silo cone. This vibrator generates high-frequency vibrations through its built-in vibrating motor and attempts to transmit this vibrational force through the silo wall to the material inside, hoping to break up the arched structure of the material and restore its fluidity. However, in practical applications, this method of indirectly transmitting vibration through the silo wall has inherent drawbacks. When the excitation force is transmitted from the silo wall to the center of the silo, the energy decreases rapidly with the increase of the transmission distance. When the vibration reaches the core area of ​​the material far from the silo wall, its strength has been greatly weakened. Therefore, for strong arches formed by highly viscous or severely compacted materials, especially those occurring in the center of the silo, the arch-breaking effect of the silo wall vibrator is often unsatisfactory, making it difficult to fundamentally solve the blockage problem. Moreover, prolonged vibration not only consumes a lot of energy but may also cause fatigue damage to the silo structure.

[0004] Therefore, this utility model proposes a novel vibrating discharge device for silos to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the fact that most existing silo vibrating discharge devices adopt external vibration of the silo wall, there are problems such as severe attenuation when the excitation force is transmitted to the center of the silo, resulting in low efficiency in breaking arches in the core area of ​​the material. This utility model aims to provide a new type of silo vibrating discharge device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a novel vibrating discharge device for a silo, which is installed on a silo cone bucket and includes a vibrating motor disposed outside the silo cone bucket; as well as a support, a connecting rod, a vibrating hammer, and a connecting pin.

[0007] The vibratory hammer is located inside the cone-shaped silo and is movably connected to the connecting rod via a connecting pin.

[0008] Furthermore, the support fixes the vibration motor to the wall panel of the silo cone, one end of the connecting rod is connected to the excitation mechanism of the vibration motor and extends through the wall panel of the silo cone into its interior, and the vibrating hammer is oscillatingly connected to the other end of the connecting rod extending into the silo cone through the connecting pin.

[0009] Preferably, the support and the silo cone are fixed by welding or bolting.

[0010] Preferably, the novel silo vibration discharge device further includes a sealing element, which is disposed at the position where the connecting rod passes through the silo cone wall plate to prevent material leakage.

[0011] Preferably, the end of the connecting rod is provided with a pin mounting hole, and the vibrating hammer is provided with a connecting lug that mates with it. The connecting pin passes through the connecting lug and the pin mounting hole to connect the two.

[0012] Preferably, the vibratory hammer is a solid metal block with a predetermined mass.

[0013] Furthermore, the end of the vibratory hammer that acts on the material has a conical or wedge-shaped structure.

[0014] Furthermore, the vibratory hammer is made of high-hardness wear-resistant alloy steel.

[0015] Preferably, the connecting rod is a high-strength metal rigid rod.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of low efficiency in breaking up arched materials in the center of the silo due to severe attenuation of excitation force transmission in existing silo wall vibrators. It achieves extremely high arch-breaking efficiency and thorough material cleaning effect.

[0017] 2. This utility model solves the problem of complex structure of some built-in arch-breaking devices or the difficulty of maintenance and repair caused by the direct contact of the power component with the material by setting the power source vibratory motor outside the bin and placing the actuator vibratory hammer inside the bin. The two are connected by a simple connecting rod and connecting pin. This achieves the technical effect of simple overall structure, stable and reliable operation, and convenient installation and maintenance.

[0018] 3. This utility model achieves rapid and efficient arch breaking by precisely applying the excitation force to the core area of ​​the blockage material. It solves the problem of high energy consumption caused by the long operation time required by traditional arch breaking methods due to low efficiency. It significantly shortens the equipment operating time, thereby achieving the technical effect of energy saving and environmental protection. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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 a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figure 1 This utility model provides a novel vibrating discharge device for silos, which aims to solve the problem in the prior art where the vibration force transmitted from the outside to the inside of the silo is severely attenuated, resulting in low efficiency in breaking up arches of the material in the center of the silo. Figure 1 As shown, the device is installed on a silo cone 6. Its basic frame includes a vibratory motor 1 as a power source, which is located on the outside of the silo cone 6. A support 2 fixes the vibratory motor 1 to the outer wall of the silo cone 6. The support 2 and the outer wall are fixedly connected by welding or bolts. A high-strength metal rigid rod connecting rod 3 serves as a transmission component. One end of the connecting rod 3 is connected to the excitation mechanism of the vibratory motor 1, and its body passes through the wall of the silo cone 6 and extends into its interior. A solid metal block vibratory hammer 5 with a predetermined mass serves as the execution component that directly acts on the material. The vibratory hammer 5 is located inside the silo cone 6. A connecting pin 4 is used to realize the movable connection between the connecting rod 3 and the vibratory hammer 5. Specifically, the vibratory hammer 5 is oscillatingly connected to the other end of the connecting rod 3, that is, the end that extends into the interior of the silo cone 6, through the connecting pin 4.

[0023] To more specifically demonstrate the arch-breaking function of this device, its structure lies in the connection and cooperation method between the connecting rod 3 and the vibratory hammer 5. Please refer to [link / reference needed]. Figure 1 To ensure the airtightness of the silo cone 6 and prevent material leakage, a seal is provided at the position where the connecting rod 3 passes through the wall of the silo cone 6 to prevent material leakage. This seal can adopt a wear-resistant flexible sealing structure. At the end of the connecting rod 3 that extends into the silo cone 6, there is a pin mounting hole. The upper end of the vibrating hammer 5 is correspondingly provided with a connecting lug. The connecting pin 4 passes through the connecting lug of the vibrating hammer 5 and the pin mounting hole of the connecting rod 3 in sequence, thereby movably connecting the two together. This connection achieved by the connecting pin 4 ensures that the vibrating hammer 5 can swing flexibly when it receives the excitation force transmitted by the connecting rod 3, thereby impacting and dispersing the arched material from multiple angles. To further improve the arch breaking efficiency, the end of the vibrating hammer 5 that acts on the material has a conical or wedge-shaped structure and is made of high-hardness wear-resistant alloy steel to enhance its ability to insert into the material and resist wear.

[0024] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a specific implementation method, in order to achieve a firm and reliable fixation between the device and the silo cone 6, the support 2 is fixed to the outer wall plate of the silo cone 6 by welding or bolting. This method is convenient to install and has high connection strength. In order to ensure that the excitation force can be stably and losslessly transmitted to the depth of the silo, the connecting rod 3 is preferably a high-strength metal rigid rod to prevent it from deforming and causing energy loss when transmitting vibration. Furthermore, in order to enhance the impact strength and service life of the vibratory hammer 5 and enable it to cope with wear in high-intensity working environments, the vibratory hammer 5 is made of high-hardness wear-resistant alloy steel. At the same time, in order to improve the efficiency of the vibratory hammer 5 in penetrating and breaking arched materials, its end acting on the material has a conical or wedge-shaped structure. This structure helps to reduce impact resistance and concentrate stress, thereby achieving a better arch-breaking effect.

[0025] Working principle: The excitation force generated by the vibrating motor 1 on the support 2 on the wall plate of the silo cone 6 is transmitted to the vibrating hammer 5 through the connecting rod 3. Since the vibrating hammer 5 and the connecting rod 3 are connected by the connecting pin 4, the vibrating hammer 5 will vibrate under the drive of the vibrating motor 1, which will disperse the arched material. At the same time, the material adhering to the silo wall will also be removed from the silo wall under the action of the vibrating motor 1, realizing that the vibrating body can directly insert into the material, which has extremely high arch breaking efficiency. At the same time, the structure is simple, energy-saving and environmentally friendly.
