Description

Technical Field

[0001] This application relates to the technical field of steel smelting, and in particular to a silicon-chromium alloy silo unloading device. Background Technology

[0002] Silicon-chromium alloys, as an important ferroalloy, have wide applications in industries such as steel smelting. In the production and processing of silicon-chromium alloys, the silo unloading device is an indispensable key piece of equipment. Its main function is to accurately and stably transport the silicon-chromium alloy stored in the silo to the target location or subsequent processing equipment according to production needs.

[0003] However, most existing silicon-chromium alloy silo feeding devices currently use a simple open-type gravity feeding method. Under the pressure of material accumulation, the feeding speed is unstable and difficult to control, which can easily lead to feeding too fast or too slow, resulting in uneven material usage in subsequent production processes, affecting product quality and production efficiency. At the same time, the discharge port size of this feeding method is fixed and cannot be flexibly adjusted according to actual production needs, which also makes it difficult to accurately control the feeding amount.

[0004] Regarding the aforementioned technologies, the inventors believe that the simple open-type gravity feeding method has the drawback of unstable and uncontrollable feeding speed, which can easily lead to feeding too fast or too slow, resulting in uneven material usage in subsequent production processes and affecting product quality and production efficiency. Utility Model Content

[0005] To address the problem of unstable and uncontrollable feeding speed in simple open-type gravity feeding methods, which can easily lead to feeding too fast or too slow, resulting in uneven material usage in subsequent production stages and affecting product quality and production efficiency, this application provides a silicon-chromium alloy silo feeding device.

[0006] This application provides a silicon-chromium alloy silo unloading device, which adopts the following technical solution:

[0007] A silicon-chromium alloy silo unloading device includes a hopper, a pipe, and a storage box. One end of the pipe is connected to the hopper, and the other end is connected to the storage box. A material control component is installed at the outlet of the storage box.

[0008] The material control assembly includes a first rotating shaft and a second rotating shaft. The first rotating shaft is installed on one side of the storage box, and the second rotating shaft is installed on the other side of the storage box. A first material control cover and a first sector gear are sleeved on the first rotating shaft, and a second material control cover and a second sector gear are sleeved on the second rotating shaft. The first sector gear and the second sector gear are meshed and connected. The first material control cover and the second material control cover are fastened together to control the material discharge from the storage box. One end of the first rotating shaft is sleeved with the first sector gear, and the other end is connected to an adjusting rod for rotating the first rotating shaft.

[0009] By adopting the above technical solution, the feeding hopper is used to receive and collect silicon-chromium alloy materials, providing a stable material source for feeding. The feeding pipe realizes the conveying and transfer of materials from high to low. The storage box plays a buffering and temporary storage role, balancing the material supply. In the material control component, the first rotating shaft is rotated by the adjusting rod. The meshing transmission of the first sector gear and the second sector gear drives the opening and closing of the first material control cover and the second material control cover, accurately controlling the size of the material box outlet, thereby realizing precise control of the material feeding amount of the storage box. This effectively solves the problems of uncontrollable feeding speed and difficulty in accurately adjusting the feeding amount of traditional feeding devices, ensuring the stability and accuracy of material use in subsequent production processes, and improving product quality and production efficiency.

[0010] Optionally, both the first and second material control covers are fan-shaped covers.

[0011] By adopting the above technical solution, the shape of the fan-shaped cover minimizes the obstruction to materials during rotation, optimizes material flow, reduces material accumulation and blockage at the discharge port, and allows for more precise adjustment of the discharge port size when the fan-shaped cover is fastened and disassembled, enabling fine control of the discharge amount.

[0012] Optionally, a first mounting plate and a second mounting plate are respectively installed at both ends of one side of the storage box, the first rotating shaft is rotatably connected to the first mounting plate and the second mounting plate, and the first material control cover is fixedly installed on the first rotating shaft;

[0013] The storage bin has a third mounting plate and a fourth mounting plate installed at both ends on the other side. The second rotating shaft is rotatably connected to the third mounting plate and the fourth mounting plate, and the second material control cover is fixedly installed on the second rotating shaft.

[0014] By adopting the above technical solution, the first mounting plate and the second mounting plate provide stable support and mounting foundation for the first rotating shaft, and the third mounting plate and the fourth mounting plate provide stable support and mounting foundation for the second rotating shaft, ensuring that the first rotating shaft and the second rotating shaft can rotate stably, thereby ensuring the stability and accuracy of the movement of the first material control cover and the second material control cover, and improving the reliability of the material control component and the accuracy of the material feeding control.

[0015] Optionally, both the first sector gear and the second sector gear are provided with a limiting plate on the side near the feed tube, and the limiting plate is installed on the storage box.

[0016] By adopting the above technical solution, the limiting plate restricts the rotation range of the first sector tooth and the second sector tooth, avoids damage to the device caused by excessive rotation of the first sector tooth and the second sector tooth, ensures that the opening and closing degree of the discharge port is within the preset safety range, and improves the safety of the device.

[0017] Optionally, the length of the first rotating shaft is greater than the length of the second rotating shaft.

[0018] By adopting the above technical solution, the longer first rotating shaft provides more suitable space for the installation and operation of the adjusting rod, making it convenient for operators to rotate the adjusting rod at a certain distance from the storage box, avoiding the inconvenience caused by the narrow operating space. At the same time, the shorter second rotating shaft can better adapt to the spatial layout on the other side of the storage box, making the entire device structure more compact and reasonable.

[0019] Optionally, the axial direction of the feeding pipe is inclined relative to the axial direction of the feeding hopper.

[0020] By adopting the above technical solution, the inclined feeding pipe increases the contact area and friction path between the silicon-chromium alloy material and the inner wall of the feeding pipe, slows down the falling speed of the material, makes the feeding process more stable, and allows the material to flow and distribute more fully in the inclined pipe, reducing local accumulation and helping the material to enter the storage box evenly, thus improving the stability and uniformity of the feeding.

[0021] Optionally, multiple vibrators are installed on the feed pipe.

[0022] By adopting the above technical solution, the high-frequency vibration generated by the vibrator can destroy the friction and adhesion between silicon-chromium alloy materials and between the materials and the pipe wall, prevent the materials from accumulating and clumping in the pipe, keep the feeding pipe unobstructed, promote material flow, speed up the feeding speed, improve the feeding efficiency, and ensure the continuity of the feeding process.

[0023] Optionally, a maintenance plate is provided at the bottom of the feeding pipe, and the maintenance plate is hinged to the feeding pipe.

[0024] By adopting the above technical solution, the hinged inspection plate provides a basis for the maintenance and repair of the feed pipe. When it is necessary to check whether there is wear, blockage or other faults inside the feed pipe, the operator only needs to open the inspection plate to directly observe and deal with the situation inside the pipe.

[0025] Optionally, the inspection plate is provided with a connecting plate, the connecting plate has a connecting hole, a connector is installed in the connecting hole, the feed tube has a threaded hole, and the connector passes through the connecting hole and is threadedly connected to the threaded hole.

[0026] By adopting the above technical solution, the connecting plate, connecting hole, connecting parts on the inspection plate cooperate with the threaded hole on the feed pipe to achieve a detachable connection of the inspection plate. This ensures that the inspection plate is firmly connected to the feed pipe during normal operation, preventing material leakage. When maintenance is required, the connecting parts can be easily disassembled to open the inspection plate. The operation is simple and the connection is reliable.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By rotating the adjusting rod of the material control component, the operator drives the first rotating shaft to rotate. The first sector gear meshes with the second sector gear, thereby changing the engagement degree of the first and second material control covers. This achieves precise control of the material feeding amount, avoiding the problem of unstable material feeding in traditional feeding methods. It ensures the accuracy of material use in subsequent production stages, thereby improving product quality, reducing production adjustments and waste caused by feeding errors, and significantly improving production efficiency.

[0029] 2. The inclined setting of the feeding pipe and the setting of the vibrator can effectively slow down the falling speed of silicon-chromium alloy materials, promote uniform material flow, prevent blockage, and ensure that the materials enter the storage box stably and continuously;

[0030] 3. The inspection plate at the bottom of the feed pipe allows operators to easily inspect, clean, and repair the inside of the feed pipe, reducing maintenance difficulty and cost. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0040] This application discloses a silicon-chromium alloy silo unloading device, referring to... Figure 1 and Figure 2 The silicon-chromium alloy silo unloading device includes a hopper 1, a pipe 2 and a storage box 3. One end of the pipe 2 is connected to the hopper 1 and the other end is connected to the storage box 3. The outlet of the storage box 3 is equipped with a material control component 4.

[0041] The material control assembly 4 includes a first rotating shaft 41 and a second rotating shaft 45. The first rotating shaft 41 is installed on one side of the storage box 3, and the second rotating shaft 45 is installed on the other side of the storage box 3. A first material control cover 42 and a first sector gear 43 are sleeved on the first rotating shaft 41, and a second material control cover 46 and a second sector gear 47 are sleeved on the second rotating shaft 45. The first sector gear 43 and the second sector gear 47 are meshed and connected. The first material control cover 42 and the second material control cover 46 are fastened together to control the material discharge from the storage box 3. One end of the first rotating shaft 41 is sleeved with the first sector gear 43, and the other end is connected to an adjusting rod 44 for rotating the first rotating shaft 41.

[0042] In this silicon-chromium alloy silo unloading device, the unloading hopper 1 serves as the initial storage and receiving component for the silicon-chromium alloy, collecting the material transported from the silo and guiding it into the unloading pipe 2. The unloading pipe 2 connects the unloading hopper 1 and the storage tank 3, providing a conveying channel for the silicon-chromium alloy material from the unloading hopper 1 to the storage tank 3. This ensures smooth transfer of the material from the unloading hopper 1 to the storage tank 3, preventing blockages or leaks during transport and ensuring the continuity and stability of the unloading process. The length and position of the unloading pipe 2 can be adjusted according to the actual installation space and production needs, thereby changing the conveying direction and path of the silicon-chromium alloy material.

[0043] The storage bin 3 can temporarily store the silicon-chromium alloy material transported from the feed pipe 2 and provide a relatively stable material environment for subsequent feeding control. It can balance the supply and demand of materials, making the feeding process more uniform and controllable. The storage bin 3 reduces fluctuations in the material conveying process, provides the basic conditions for precise control of the feeding amount, and helps to improve product quality and production efficiency.

[0044] The first rotating shaft 41 and the second rotating shaft 45 of the material control assembly 4 serve as support and rotation components, respectively installed on both sides of the storage box 3. They provide support points for the installation and rotation of the first material control cover 42, the first sector gear 43, the second material control cover 46, and the second sector gear 47, ensuring that the material control cover and sector gear can rotate stably and accurately. The material control assembly 4 can drive the corresponding material control cover and sector gear to move through the rotation of the shafts, thereby realizing the opening and closing control of the discharge port and providing a mechanical basis for precise control of the material discharge amount.

[0045] The first control cover 42 and the second control cover 46 are fastened together at the discharge port of the storage box 3. The opening size of the discharge port of the storage box 3 can be adjusted by changing the degree of fastening between the two. When the two are fastened tightly, the discharge port of the storage box 3 is closed and the material stops being discharged; when the two are gradually separated, the discharge port opens and the material begins to be discharged. The larger the opening, the faster the discharge speed.

[0046] The opening and closing of the first control cover 42 and the second control cover 46 can flexibly and accurately control the discharge amount and discharge speed of the storage box 3, and adjust the discharge amount in real time according to production needs to avoid the discharge being too fast or too slow, thereby improving product quality and production efficiency.

[0047] The first sector gear 43 and the second sector gear 47 are meshed together to transmit the rotation of the first rotating shaft 41 to the second rotating shaft 45, enabling the first material control cover 42 and the second material control cover 46 to rotate synchronously and in opposite directions, thereby controlling the opening and closing of the discharge port. The meshing connection of the first sector gear 43 and the second sector gear ensures that the movements of the first material control cover 42 and the second material control cover 46 are coordinated, improving the accuracy and stability of material control and avoiding uneven material feeding caused by inconsistent movements between the two.

[0048] An adjusting rod 44 is connected to one end of the first rotating shaft 41. The operator can manually rotate the adjusting rod 44 to drive the first rotating shaft 41 to rotate, thereby controlling the opening and closing degree of the first material control cover 42 and the second material control cover 46. The adjusting rod 44 provides the operator with a convenient operating method, allowing for real-time adjustment of the material feeding amount according to actual production conditions, achieving real-time control of the feeding process without the need for complex equipment and operating procedures, thus reducing labor intensity and operational difficulty.

[0049] The silicon-chromium alloy silo unloading device collects materials through the unloading hopper 1, transports materials through the unloading pipe 2, temporarily stores materials in the storage box 3, and precisely controls the unloading amount through the material control component 4, forming a complete unloading system. Overall, it realizes the orderly and precise unloading process of silicon-chromium alloy from the silo to the subsequent processing equipment.

[0050] The device rotates the first shaft 41 by rotating the adjusting rod 44, and the first sector gear 43 meshes with the second sector gear 47 to drive the transmission, thereby changing the engagement degree of the first material control cover 42 and the second material control cover 46, and realizing flexible adjustment of the size of the discharge port of the storage box 3. When it is necessary to reduce the feeding speed, the adjusting rod 44 can be rotated to make the first material control cover 42 and the second material control cover 46 engage more tightly and reduce the size of the discharge port; conversely, the discharge port can be enlarged to increase the feeding speed. The device can flexibly adjust the size of the discharge port according to production needs, realize precise control of the feeding amount, avoid the problems of unstable feeding speed and difficulty in precise control of feeding amount in traditional feeding methods, and improve product quality and production efficiency.

[0051] The axis of the feeding pipe 2 is inclined relative to the axis of the feeding hopper 1. Compared to a vertically arranged feeding pipe 2, the inclined arrangement increases the contact area and friction path between the material and the inner wall of the feeding pipe 2. When the material slides down the inclined feeding pipe 2, it experiences greater friction, which slows down the falling speed of the material, making the feeding process smoother and avoiding sudden increases in the feeding volume caused by excessively fast material falling. This makes the feeding speed more stable and controllable, which is beneficial for subsequent precise adjustment of the feeding volume.

[0052] In addition, the inclined feed pipe 2 allows the material to flow and distribute more fully within the pipe, reducing the possibility of local accumulation of material within the pipe. This helps the material to enter the storage bin 3 evenly, providing better conditions for the subsequent material control components 4 to precisely control the feeding, and helping to ensure the stability and accuracy of the entire feeding process.

[0053] Multiple vibrators 5 are installed on the feeding pipe 2. During the falling process, the silicon-chromium alloy material may become blocked in the feeding pipe 2 due to its own stickiness, the friction between particles, or the accumulation in the pipe. The vibrators 5 generate high-frequency vibration, which makes the inner wall of the feeding pipe 2 vibrate continuously, destroying the friction and adhesion between the materials and between the materials and the pipe wall, thereby preventing the materials from accumulating and agglomerating in the pipe, keeping the feeding pipe 2 unobstructed, reducing equipment failures and downtime caused by material blockage, improving the reliability and stability of the feeding device, and ensuring the continuity of the production process.

[0054] The vibration of vibrator 5 can apply additional power to the material, causing it to flow more smoothly downwards under the influence of gravity. Especially for some silicon-chromium alloy materials with poor flowability, vibrator 5 can accelerate the falling speed of the material and improve the feeding efficiency. The vibration of vibrator 5 can also make the material more evenly distributed in the pipeline, avoiding situations where there is too much or too little material in some areas, thus ensuring the uniformity of feeding.

[0055] Reference Figure 2 A maintenance plate 21 is installed at the bottom of the feeding pipe 2. The maintenance plate 21 is hinged to the feeding pipe 2. By opening the hinged maintenance plate 21, the operator can directly observe the internal condition of the feeding pipe 2 and promptly identify potential problems, such as the degree of wear on the inner wall of the pipe and whether there is any accumulation of foreign objects. When material accumulation or blockage is found inside the feeding pipe 2, the maintenance plate 21 can be opened to facilitate the cleaning of the material inside the pipe. For some blockage problems caused by material adhesion or agglomeration, the maintenance plate 21 provides a direct access point, making it easy to use tools for unblocking. In addition, the maintenance plate 21 can also be used for regular cleaning and maintenance of the inside of the feeding pipe 2 to prevent material residue from affecting the feeding effect and improve the reliability and stability of the feeding device.

[0056] The inspection plate 21 is provided with a connecting plate 22, which has a connecting hole. A connector 23 is installed in the connecting hole. The feed pipe 2 has a threaded hole. The connector 23 passes through the connecting hole and is threadedly connected to the threaded hole. The connecting plate 22 provides a stable connection platform for connecting the inspection plate 21 and the feed pipe 2. By opening the connecting hole, it provides a position for the installation of the connector 23, so that the inspection plate 21 can be reliably connected to the feed pipe 2. This ensures that the inspection plate 21 will not loosen or fall off due to material impact, vibration or other factors during normal feeding, and ensures the sealing and safety of the feeding process.

[0057] The connecting hole is the channel through which the connector 23 passes, serving to position and guide the connector 23, ensuring that it accurately mates with the threaded hole on the feed pipe 2. The connector 23 is typically a threaded connector such as a bolt, which passes through the connecting hole and connects threadedly to the threaded hole on the feed pipe 2, firmly fixing the inspection plate 21 to the feed pipe 2. By tightening the connector 23, the tightness of the connection between the inspection plate 21 and the feed pipe 2 can be adjusted. The connector 23 ensures a secure connection during normal operation, preventing material leakage, and also allows for easy disassembly of the connector 23 to open the inspection plate 21 for internal maintenance when needed. The threaded hole provides a fixing point for the threaded connection, enabling the connector 23 to tightly fix the inspection plate 21 to the feed pipe 2, ensuring the strength and stability of the connection between the inspection plate 21 and the feed pipe 2, and providing a reliable structural guarantee for the normal operation of the feed pipe 2.

[0058] Reference Figure 1 and Figure 2 A first mounting plate 31 and a second mounting plate 32 are respectively installed at both ends of one side of the storage box 3. A first rotating shaft 41 is rotatably connected to the first mounting plate 31 and the second mounting plate 32. A first material control cover 42 is fixedly installed on the first rotating shaft 41. The first mounting plate 31 and the second mounting plate 32 provide support and mounting foundation for the first rotating shaft 41. They are firmly connected to the storage box 3 to ensure that the first rotating shaft 41 can rotate stably, ensuring the installation accuracy and stability of the first rotating shaft 41. This prevents the first rotating shaft 41 from shaking or deviating during rotation, providing reliable support for the precise movement of the first material control cover 42, thereby ensuring the accuracy of material feeding control.

[0059] The storage bin 3 has a third mounting plate 33 and a fourth mounting plate 34 installed at both ends on the other side. The second rotating shaft 45 is rotatably connected to the third mounting plate 33 and the fourth mounting plate 34 respectively. The second material control cover 46 is fixedly installed on the second rotating shaft 45. The third mounting plate 33 and the fourth mounting plate 34 provide support and installation foundation for the second rotating shaft 45, ensuring that the second rotating shaft 45 can rotate stably and ensuring the stable operation of the second rotating shaft 45. This allows the second material control cover 46 to move accurately according to the design requirements and work in coordination with the first material control cover 42 to achieve precise control of the material outlet of the storage bin 3.

[0060] The first rotating shaft 41 serves as the mounting carrier for the first material control cover 42. Through a fixed connection, the first material control cover 42 rotates with the rotation of the first rotating shaft 41. The first rotating shaft 41 transmits the rotation of the adjusting rod 44 to the first material control cover 42, thereby controlling the movement of the first material control cover 42. The first rotating shaft 41 can accurately transmit the power applied by the operator through the adjusting rod 44 to the first material control cover 42, enabling the first material control cover 42 to rotate as required, thereby changing the degree of engagement with the second material control cover 46 and controlling the amount of material fed.

[0061] The second rotating shaft 45 serves as the mounting carrier for the second material control cover 46. It transmits the rotation from the first sector gear 43 to the second material control cover 46, causing the second material control cover 46 to rotate. This ensures that the second material control cover 46 can rotate synchronously and in opposite directions with the first material control cover 42, making their locking actions coordinated and consistent. This allows for precise control of the opening size of the material storage box 3's outlet, improving the accuracy of material feeding control.

[0062] Reference Figure 1 and Figure 3 Each of the first sector gear 43 and the second sector gear 47 is equipped with a limiting plate 35 on the side near the discharge pipe 2. The limiting plate 35 is installed on the storage box 3. When the first sector gear 43 and the second sector gear 47 rotate to a certain position, the limiting plate 35 will prevent the first sector gear 43 and the second sector gear 47 from continuing to rotate towards the discharge pipe 2. This can prevent the first sector gear 43 and the second sector gear 47 from rotating excessively and colliding or interfering with the discharge pipe 2 or other components, thus preventing damage to the device and extending its service life. In this application, the limiting plate 35 will prevent the first material control cover 42 and the second material control cover 46 from rotating excessively, limiting the minimum opening and closing degree of the first material control cover 42 and the second material control cover 46. This ensures that when it is necessary to close the discharge port, the first material control cover 42 and the second material control cover 46 can be tightly fastened to prevent material leakage and ensure the sealing of the storage box 3. The limiting plate 35 can prevent the sector gears from rotating excessively, thus preventing the transmission structure from becoming loose or damaged, and maintaining the stability and reliability of the entire material control assembly 4.

[0063] Both the first control cover 42 and the second control cover 46 are fan-shaped covers. The fan-shaped design allows the material to flow more smoothly during the discharge process. Compared with control covers of other shapes, the fan-shaped cover obstructs the material less during rotation, reducing material accumulation and blockage at the discharge port, and allowing the material to flow out evenly and stably. When it is necessary to stop feeding or reduce the feeding amount, the first control cover 42 and the second control cover 46 of the fan-shaped cover can be tightly fastened to effectively prevent material from flowing out, providing a good sealing effect, preventing material leakage and scattering, and maintaining a clean production environment.

[0064] The length of the first rotating shaft 41 is greater than the length of the second rotating shaft 45. The longer first rotating shaft 41 provides more suitable space for the installation and operation of the adjusting rod 44. The operator can conveniently rotate the adjusting rod 44 at a certain distance from the storage box 3, avoiding inconvenience or misoperation caused by narrow operating space.

[0065] The implementation principle of the silicon-chromium alloy silo feeding device in this application embodiment is as follows: The silicon-chromium alloy material is first stored in the feeding hopper 1. Relying on gravity, the material flows downward along the inclined feeding pipe 2. The vibrator 5 installed on the feeding pipe 2 uses high-frequency vibration to break the friction and adhesion between the materials and between the materials and the pipe wall, promoting smoother downward flow of the material and reducing the possibility of blockage. After passing through the feeding pipe 2, the material enters the storage box 3. The storage box 3 plays the role of buffering and temporarily storing the material, providing a stable material supply for subsequent precise feeding.

[0066] A material control component 4 is installed at the discharge port of the storage box 3. When the operator rotates the adjusting rod 44 connected to the first rotating shaft 41, the first rotating shaft 41 rotates accordingly. Through the meshing of the first sector gear 43 and the second sector gear 47, the second rotating shaft 45 is driven to rotate in the opposite direction, so that the first material control cover 42 and the second material control cover 46 rotate synchronously and in opposite directions. That is, by changing the degree of engagement of the two material control covers, the opening size of the discharge port can be flexibly adjusted, thereby precisely controlling the amount of silicon-chromium alloy discharged.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
