Description

Technical Field

[0001] This utility model relates to the field of hopper anti-blocking technology, specifically to an anti-jamming device for a blast furnace charging bin. Background Technology

[0002] In the metallurgical industry, blast furnaces are crucial smelting equipment, and the stable operation of the blast furnace charging system directly affects the blast furnace's production efficiency and product quality. As a key component of the blast furnace charging system, the hopper is used to store and temporarily store materials waiting to be charged. However, in actual production, due to the wide variety of materials, such as ores and coke, their physical properties (such as particle size, moisture content, and viscosity) vary, which often leads to material jamming in the hopper.

[0003] Material jamming can cause poor material feeding or even blockage, seriously affecting the continuous feeding of the blast furnace, which in turn leads to the interruption of the blast furnace smelting process, reduces production efficiency, and increases production costs. Currently, the traditional solution to the material jamming problem in the bucket is to install a vibrating motor on the outer wall of the bucket, so that the material blocks can be loosened by vibration and fall quickly, reducing the accumulation of material blocks and jamming.

[0004] However, while vibratory motors can alleviate material jamming to some extent, the gaps between material blocks are further compressed during vibration, causing the rough surfaces and edges of the material blocks to fit together more tightly, resulting in a "more vibration, more compaction" situation. This can exacerbate material accumulation, thereby reducing production efficiency and potentially shortening the lifespan of the equipment. Utility Model Content

[0005] In view of this, the present invention provides an anti-jamming device for a blast furnace charging bin. The device can break up the blockage structure of the material blocks by vibrating the vibrating motor on the outside of the mounting frame, causing them to fall loosely. The inner frustum-shaped blocking plate is fixed by the connecting column and guides the material blocks to slide evenly with an inclined surface, avoiding concentrated falling and "the more it vibrates, the more compacted it becomes", reducing the risk of blockage and ensuring stable charging.

[0006] To solve the above-mentioned technical problems, this utility model provides an anti-jamming device for a blast furnace charging bin, including a mounting frame. Mounting plates are fixedly connected to the outer walls of the upper and lower ends of the mounting frame. A vibration motor is installed on the outer wall of the mounting frame. A support frame is bolted to the outer wall of the mounting frame. The vibration motor is bolted to one vertical surface of the support frame.

[0007] Mounting brackets are snapped into the grooves on both sides of the vibratory motor. The mounting brackets are connected to the support frame or mounting frame by bolts to assist in fixing the vibratory motor and further fix the vibratory motor.

[0008] At least one connecting post is provided on the inner wall of the mounting frame, and a blocking plate is provided at the end of the connecting post facing the axis of the mounting frame (i.e., one end of the connecting post is connected to the blocking plate).

[0009] The blocking disc is designed as a frustum-shaped structure, with its outer side wall forming an inclined surface to guide the material block to slide down along the inclined surface in all directions.

[0010] The blocking disc is designed with a conical structure, and the upper end of the conical structure is pointed, which can effectively prevent material blocks from accumulating on the upper end of the blocking disc, further improving the material distribution and guiding effect and reducing material retention.

[0011] The bottom of the blocking plate is designed as a hollow structure to reduce the overall weight and the load on the mounting frame and connecting column, without affecting the material blocking function of the blocking plate.

[0012] A reinforcing disc is fixedly connected to the lower part of the blocking disc to enhance its structural strength and prevent it from bending or deforming under long-term impact from the receiving blocks.

[0013] The connecting column is designed as a cylindrical structure to prevent material from accumulating on the outer wall of the connecting column.

[0014] Both ends of the connecting column are connected to a fixing cylinder by thread. The two fixing cylinders are fixedly connected to the inner side wall of the fixing frame and the outer side wall of the blocking plate, respectively, which facilitates disassembly and maintenance.

[0015] A guide plate is fixedly connected to the inner wall of the mounting frame and above the connecting column. The upper surface of the guide plate is set as an inclined surface, which is inclined towards the axis of the mounting frame.

[0016] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0017] 1. Improved material discharge efficiency: By installing a vibrating motor on the outside of the mounting frame, continuous or intermittent vibration can be generated, transmitting the vibration force to the mounting frame, breaking up the congested structure of the material blocks, causing them to loosen and fall quickly. At the same time, the blocking plate on the inside of the mounting frame is designed with a conical structure, and the inclined surface of its outer wall can guide the material blocks to slide evenly in all directions along the inclined surface, forcibly changing the flow direction of the material blocks, avoiding concentrated falling of material blocks or compaction due to vibration, effectively solving the "more vibration, more compaction" problem that may be caused by traditional vibrating motors, reducing the risk of material blocks clogging in the hopper, and ensuring the continuous and stable operation of the blast furnace charging system.

[0018] 2. Strong material distribution and anti-accumulation capabilities: The upper end of the conical blocking disc has a pointed structure, which can effectively prevent material blocks from accumulating on the upper end of the blocking disc. Combined with the inclined surface design, the material is more evenly distributed on the cross-section of the hopper, avoiding the formation of a "funnel flow" that falls straight down from the center, and reducing the phenomenon of material blocks stagnating or getting stuck at the edges. The smooth inclined surface can also reduce the frictional resistance of the material blocks. Combined with the vibration effect, it promotes the rapid and even sliding of the material blocks, further improving the material distribution and guidance effect and reducing material retention.

[0019] 3. Improved stability through optimized baffle structure: The bottom of the baffle adopts a hollow structure, which reduces the overall weight without affecting the material distribution and blocking function, reduces the load on the mounting frame and connecting columns, and improves the stability of equipment installation; the reinforcing plate at the bottom of the baffle can enhance the structural strength of the baffle, prevent it from bending and deforming under long-term impact from material blocks, and extend the service life of the device.

[0020] 4. Stable installation structure of the vibratory motor: The support frame on the outside of the mounting frame provides a stable mounting plane and support point for the vibratory motor, ensuring that the vibratory motor will not loosen, shift or fall off due to its own vibration during operation, and can directly transmit the vibration force to the mounting frame with almost no loss, improving the vibration effect; the mounting brackets at the grooves on both sides of the vibratory motor can fix it a second time, further strengthening the support stability and avoiding motor displacement or swaying caused by bolt vibration fatigue loosening, ensuring the smooth operation of the vibratory motor.

[0021] 5. Easy to disassemble, maintain and clean: The two ends of the connecting column are connected to the inner side wall of the mounting frame and the outer side wall of the baffle plate respectively through threaded fixed cylinders, which facilitates quick disassembly of damaged parts (such as the baffle plate that has deformed after long-term use), greatly simplifying the disassembly and maintenance process of the equipment; the upper surface of the guide plate on the inner side wall of the mounting frame is provided with an inclined surface facing the axis, which can guide the falling material blocks and prevent edge material blocks from continuously falling at the fixed cylinder connection, avoiding the failure of the fixed cylinder connection, while blocking the dust generated by the vibration of the material blocks, keeping the equipment clean and reducing maintenance costs.

[0022] 6. Prevents material accumulation and improves reliability: The connecting column adopts a cylindrical structure, and its smooth outer wall prevents material accumulation, ensuring that the connecting column remains clean for a long time and avoiding the impact of material retention on equipment operation; the inclined design of the guide plate not only guides the material to be evenly distributed, but also reduces the impact of dust on the internal structure of the equipment, further improving the reliability and practicality of the device.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0033] A device for preventing material jamming in a blast furnace charging bin, such as Figure 1 As shown: It includes a mounting frame 101, and mounting plates 105 are fixedly connected to the outer walls of the upper and lower ends of the mounting frame 101. The mounting frame 101 is used to connect the mounting frame 101 to the discharge end of the bin by bolts or to the middle part of the bin when the bin is not in production (connecting the mounting frame 101 to the middle part of the bin is the best effect).

[0034] like Figure 1 , 3 As shown: A vibration motor 102 is provided on the outer wall of the mounting frame 101. The continuous or intermittent vibration generated by the vibration motor 102 can transmit the vibration force to the mounting frame 101, thereby breaking the blockage structure of the material block (such as causing the material block to fall after being loosened by vibration), reducing the risk of material block accumulation and jamming.

[0035] A support frame 301 is bolted to the outer wall of the mounting frame 101. The support frame 301 provides a stable and reliable mounting surface and support point for the vibratory motor 102, ensuring that the vibratory motor 102 will not loosen, shift, or fall off due to its own vibration during operation. Furthermore, the support frame 301 can serve as a connecting bridge between the vibratory motor 102 and the mounting frame 101, enabling the vibration generated by the vibratory motor 102 to be transmitted to the mounting frame 101 with almost no loss, thus avoiding a large loss or absorption of vibration force and preventing it from being effectively applied to the material.

[0036] The vibration motor 102 is bolted to one side of the vertical surface of the support frame 301, which facilitates the disassembly and assembly of the vibration motor 102, making it easy to quickly disassemble and assemble during maintenance or replacement.

[0037] like Figure 1 , 2 As shown in Figure 4: At least one connecting post 103 is provided on the inner side wall of the mounting frame 101, and a blocking plate 104 is provided at one end of the connecting post 103 facing the mounting frame 101 and the axis of the mounting frame 101 (that is, one end of the connecting post 103 is connected to the blocking plate 104).

[0038] The blocking disc 104 is installed at the center or below the hopper along with the mounting frame 101. It can directly intercept densely falling material blocks, blocking them and preventing them from falling too densely and causing blockage in the hopper. In this embodiment, four connecting columns 103 are provided to better support the mounting frame 101 and avoid affecting the falling of material blocks.

[0039] Furthermore, the blocking disc 104 is configured as a frustum-shaped structure, with its outer wall forming an inclined surface to guide the material block to slide down in all directions along the inclined surface. The frustum-shaped blocking disc 104 allows the material block to slide down evenly in all directions along its inclined surface, making the material more evenly distributed on the cross-section of the bin, forcibly changing the flow direction of the material block, avoiding the material block from falling in a concentrated manner or being compacted due to vibration, and reducing the risk of blockage in the bin.

[0040] Preferably, the blocking disc 104 is configured as a conical structure with a pointed upper end, which can effectively prevent material blocks from accumulating on the upper end of the blocking disc 104, further improving the material distribution and guiding effect, and reducing material retention. Traditional silos tend to form a "funnel flow" that falls straight down from the center, and material blocks at the edges are prone to stagnation or jamming.

[0041] The conical inclined surface of the blocking disc 104 makes it easier to guide the material to slide evenly along the conical surface to the surrounding area. It can also prevent the material from staying on the upper part of the blocking disc 104, thus preventing the blocking disc 104 from becoming a blockage point. This further reduces the risk of blockage in the hopper. In addition, the smooth inclined surface can reduce the frictional resistance of the material. Combined with the vibration effect of the vibrating motor 102, the material can slide quickly and evenly to the surrounding area. By actively intervening in the flow pattern of the material, the blockage problem is solved.

[0042] like Figure 2 , 4 As shown: The bottom of the blocking plate 104 is set as a hollow structure to reduce the overall weight and the load on the mounting frame 101 and the connecting column 103, while not affecting the material blocking function of the blocking plate 104.

[0043] A reinforcing disc 201 is fixedly connected to the lower part of the blocking disc 104 to enhance the structural strength of the blocking disc 104 and prevent the blocking disc 104 from bending or deforming under long-term impact from the receiving block.

[0044] like Figure 4 As shown: The connecting column 103 is set as a cylindrical structure to prevent material from accumulating on the outer wall of the connecting column 103. The connecting column 103 can also suspend and fix the blocking plate 104, withstand the impact force of the material, and transmit the vibration force to the blocking plate 104 to ensure that the blocking plate 104 will not shift during long-term operation.

[0045] like Figure 3 As shown: mounting brackets 302 are snapped into the grooves on both sides of the vibration motor 102. The mounting brackets 302 are connected to the support frame 301 or the mounting frame 101 by bolts, which are used to assist in fixing the vibration motor 102 and further fix the vibration motor 102.

[0046] The vibration motor 102 is fixed to the support frame 301 by only the bottom bolts. After long-term operation, the bolts may loosen due to vibration fatigue, and the vibration motor 102 may experience slight displacement or swaying. By setting two mounting brackets 302, the vibration motor 102 can be fixed again, which can further strengthen the support stability of the vibration motor 102 and make the vibration motor 102 run more smoothly.

[0047] like Figure 2 , 4 As shown: Both ends of the connecting column 103 are connected to the fixing cylinder 401 by threaded connection. The two fixing cylinders 401 are fixedly connected to the inner side wall of the fixing frame and the outer side wall of the blocking plate 104, respectively, which facilitates disassembly and maintenance. This allows for quick removal of damaged parts that need to be replaced (such as the blocking plate 104 that has been deformed after long-term use) and facilitates cleaning and maintenance.

[0048] like Figure 1 , 2 As shown: A guide plate 501 is fixedly connected to the inner side wall of the mounting frame 101 and above the connecting column 103. The upper part of the guide plate 501 is set as an inclined surface, which is inclined towards the axis of the mounting frame 101. This can guide the falling material blocks, prevent the material blocks at the edge from continuously falling at the connection of the fixed cylinder 401, prevent the connection of the fixed cylinder 401 from failing, and block the dust generated by the continuous vibration of the material blocks.

[0049] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
