The deflector plate sleeved on the lower middle part of the rotating rod moves in a circular motion with the rotating rod. During rotation, the deflector plate continuously agitates the material inside the bin, making the material more evenly distributed within the bin, breaking up clumps formed by the material's own weight, preventing material from sticking to the bin walls and jamming at the discharge end from the source, ensuring continuous feeding, and simultaneously pushing the material towards the discharge end of the feeding bin, preventing material from accumulating and clogging in the bin, especially in the lower area where the inner diameter decreases.

Description

Technical Field

[0001] This application relates to the field of automated material handling equipment, and in particular to a conveying device for a mixture of silicon manganese iron nitride. Background Technology

[0002] In the production, processing, and subsequent applications of silicon nitride-manganese-iron mixtures (such as metallurgical auxiliaries and special ceramic raw materials), material conveying is a crucial link connecting various processes. However, this type of material has characteristics such as high hardness, easy moisture absorption and agglomeration, and uneven particle size. Traditional feed silos are mostly cylindrical or simple funnel structures without active anti-clogging design. After the silicon nitride-manganese-iron mixture is mixed, some fine particles are prone to forming lumps due to moisture absorption or compression, accumulating in corners and outlets of the silo, forming bridging (material is suspended and blocked in the silo, with no material discharged below) or stagnation (material slowly adheres to the silo wall, resulting in a reduction in effective volume). Even without obvious agglomeration, the material is prone to segregation due to differences in particle size distribution (mixing of coarse and fine particles), resulting in uneven material flow, with inconsistent speeds. Subsequent conveying mechanisms (such as augers and belts) are prone to frequent shutdowns due to material interruption or overload, affecting production continuity. Utility Model Content

[0006] Preferably, it also includes a conical material distribution column installed inside the hopper with its cone tip facing upwards; and a cross plate installed on the bottom surface of the conical material distribution column, with the four sides of the cross plate fixedly connected to the inside of the hopper.

[0008] Preferably, the conveying mechanism further includes an inclined conveying pipe, which is inclined upward and has its inlet connected to the outlet of the horizontal conveying pipe; a second conveying rod, which is inclinedly inserted inside the inclined conveying pipe and has one end rotatably connected to the pipe wall of the inclined conveying pipe through a bearing; a second conveying auger, which is sleeved on the outer wall of the second conveying rod and has blades that are clearance-fitted with the inner wall of the inclined conveying pipe to push the material upward along the inclined direction; and a second motor, which is installed on the top outer wall of the inclined conveying pipe and has its output end connected to the end of the second conveying rod.

[0009] Preferably, it also includes a shaft, which is horizontally inserted into the conveying cavity and rotatably connected to the cavity wall of the conveying cavity at both ends by bearings; a rotating blade, which is symmetrically installed on the outer wall of the shaft; and a third motor, which is installed on the outer wall of the conveying cavity and whose output end is connected to the end of the shaft.

The output end of the first motor drives the rotating rod, which is vertically installed in the feed bin, to rotate synchronously. The baffle plate, which is sleeved in the lower part of the rotating rod, moves in a circular motion with the rotating rod. During the rotation, the baffle plate will continuously stir the material in the bin, making the material more evenly distributed in the bin, breaking up the clumps formed by the material due to its own weight, and preventing the material from sticking to the bin wall and getting stuck at the discharge end from the source, ensuring the continuity of feeding. At the same time, it pushes the material to move towards the discharge end of the feed bin, preventing the material from accumulating and blocking in the bin, especially in the lower area where the inner diameter is narrowed.

[0013] 2. The hopper is driven by a vibrating motor to make slight vibrations in the vertical direction. During the vibration, the material in the hopper will be loosened by the high-frequency vibration and move quickly towards the discharge end of the hopper. At the same time, the slight vibration can make the inner wall of the hopper free of material residue, reducing material waste. The conical distribution column disperses the impact of the material, and the vibrating motor breaks up the material agglomeration, solving the problem of easy blockage of the funnel-shaped structure.

[0016] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0017] This application discloses a conveying device for a silicon nitride manganese ferrometallurgical mixture. (Refer to...) Figure 1 and Figure 5The system includes a feeding hopper 1 with an inner diameter that gradually decreases from top to bottom and an inlet 4 at the top. A first motor 2 is installed at the center of the top surface of the feeding hopper 1. The first motor 2 is a YE2 series three-phase asynchronous motor (power 1.5kW, speed 1450r / min) and is fixed to the motor base on the top surface of the feeding hopper 1 with bolts. A rotating rod 3 is vertically installed inside the feeding hopper 1 and its top end is connected to the output end of the first motor 2, rotating synchronously with the first motor 2. A lever 17 is sleeved on the middle and lower part of the rotating rod 3. The rotating rod 3 is a steel rod and is connected to the output end of the first motor 2 through a flexible coupling. The lever 17 is a stainless steel plate. A vibrating unloading assembly 6 is installed below the discharge end of the feeding hopper 1 to receive the material discharged from the feeding hopper 1 and to achieve anti-clogging unloading. A conveying mechanism is connected below the discharge end of the vibrating unloading assembly 6 to convey the material in horizontal and inclined directions. A bracket 5 is sleeved on the outside of the feeding hopper 1.

[0018] Material is fed into the feed hopper 1 through inlet 4 on the top surface. As the inner diameter of the feed hopper 1 gradually decreases from top to bottom, the material will naturally converge downwards to the discharge end. At this time, the first motor 2 is started, and its output end drives the rotating rod 3, which is vertically inserted into the feed hopper 1, to rotate synchronously. The deflector plate 17, which is sleeved in the lower part of the rotating rod 3, moves in a circular motion with the rotating rod 3. During the rotation, the deflector plate 17 will continuously stir the material in the hopper, making the material more evenly distributed in the hopper, breaking up the clumps formed by the material due to its own weight, and preventing material from sticking to the hopper wall and getting stuck at the discharge end from the source, ensuring continuous feeding. At the same time, it pushes the material towards the discharge end of the feed hopper 1, preventing the material from accumulating and blocking in the hopper, especially in the lower area where the inner diameter decreases.

[0019] Reference Figure 3 The vibratory unloading assembly 6 includes a hopper 601, which is funnel-shaped with a wider top and a narrower bottom. The top opening is the feed end, and the bottom is the discharge end. A corrugated telescopic feed pipe 603 is sealed at both ends to the discharge end of the feed bin 1 and the feed end of the hopper 601 via flanges 605, respectively. At least four elastic columns 604 are circumferentially and evenly distributed between the flanges 605 and the hopper 601. The top ends are fixedly connected to the outer wall of the hopper 601, and the bottom ends are fixedly connected to the top surface of the flanges 605. These columns support the hopper 601 and buffer vibrations. A vibratory motor 602 is installed in the middle of the outer wall of the hopper 601. The vibratory motor 602 is a YZU type. The series vibration motor 602 (power 0.75kW, excitation force 5kN) is fixed to the motor bracket on the outer wall of the hopper 601 by bolts. It is used to drive the hopper 601 to vibrate slightly in the vertical direction. The corrugated telescopic discharge pipe 606 is sealed at both ends to the discharge end of the hopper 601 and the feed end of the conveying mechanism through flanges 605 respectively. The corrugated telescopic feed pipe 603 and the corrugated telescopic discharge pipe 606 are made of fluororubber, with a pressure resistance of 0.6MPa, and can compensate for vibration displacement of ±50mm.

[0020] The elastic column 604 includes an outer sleeve, an inner rod, and a compression spring. The outer sleeve is vertically fixed to the flange 605 with an open top. The bottom end of the inner rod is slidably inserted into the inner sleeve, and the top end is fixed to the outer wall of the hopper 601. The compression spring is sleeved on the outside of the inner rod, and its two ends abut against the top end of the outer sleeve and the outer wall of the hopper 601, respectively. The outer sleeve of the elastic column 604 is a seamless steel pipe, the inner rod is a steel rod, and the compression spring is 65Mn spring steel. It can bear the weight of the material in the hopper 601 and buffer vibration.

[0021] The material discharged from the feed hopper 1 enters the hopper 601 through the corrugated telescopic feed pipe 603 (both ends of the corrugated pipe are sealed by flanges 605 to ensure no leakage of material). The hopper 601 is funnel-shaped with a wider top and a narrower bottom. The material first contacts the conical distribution column 19 (with the cone tip facing upward) inside the hopper 601. The distribution column disperses the concentrated falling material to the surrounding area, avoiding the material from directly impacting the center of the hopper 601 and causing blockage. The four sides of the cross plate 18 are fixed to the inner wall of the hopper 601, which not only fixes the position of the distribution column, but also helps to disperse the material.

[0022] The vibrating motor 602 drives the hopper 601 to vibrate slightly in the vertical direction. During the vibration, the material in the hopper 601 will be loosened by the high-frequency vibration and move quickly towards the discharge end of the hopper 601. At the same time, the slight vibration can ensure that there is no material residue on the inner wall of the hopper 601, reducing material waste. At this time, the elastic column 604 (including outer sleeve, inner rod, and compression spring) between the hopper 601 and the flange 605 plays a role. The inner rod can slide in the outer sleeve, and the compression spring buffers the vibration impact force, which not only ensures the stability of the vibration amplitude of the hopper 601, but also avoids the vibration from being transmitted to the feed bin 1 or the subsequent conveying mechanism, which would cause damage to the components. Finally, the material enters the conveying mechanism through the corrugated telescopic discharge pipe 606. The corrugated pipe can adapt to the vibration displacement of the hopper 601 and avoid the hard connection from breaking. Reference Figure 4 It also includes a conical material distribution column 19, which is installed inside the hopper 601 with its cone tip facing upwards, and a cross plate 18, which is installed on the bottom surface of the conical material distribution column 19. The four sides of the cross plate 18 are fixedly connected to the inside of the hopper 601. The conical material distribution column 19 disperses the impact of materials, and the vibration motor 602 breaks up material agglomeration, solving the problem of easy clogging of the funnel-shaped structure.

[0023] Reference Figure 3The conveying mechanism includes a conveying chamber 7, the top of which is sealed to the discharge end of a corrugated telescopic discharge pipe 606 via a flange 605. It also includes a shaft 15, which is horizontally inserted into the conveying chamber 7 and rotatably connected to the chamber wall of the conveying chamber 7 at both ends via bearings. A rotating blade 16 is symmetrically installed on the outer wall of the shaft 15. A third motor 14 is installed on the outer wall of the conveying chamber 7 and its output end is connected to the end of the shaft 15. The third motor 14 is a YE2 series motor (power 1.1kW, speed 960r / min). The shaft 15 is a steel rod and the rotating blade 16 is a blade, which can assist in pushing the material to be discharged.

[0024] Material discharged from the vibratory unloading assembly enters the conveying chamber 7. The third motor 14 is started, and its output end drives the shaft 15, which is horizontally inserted in the conveying chamber 7, to rotate. The rotating blades 16, which are symmetrically installed on the outer wall of the shaft 15, rotate synchronously with the shaft 15. The blades of the rotating blades 16 are in clearance fit with the inner wall of the conveying chamber 7. When rotating, they push the material in the conveying chamber 7 toward the discharge end. Finally, the material enters the subsequent horizontal conveying pipe 8 through the discharge pipe 13 at the discharge end of the conveying chamber 7. As a transition structure of the horizontal conveying pipe 8 of the vibratory unloading assembly 6, the rotating blades 16 can prevent material from accumulating at the junction, ensuring the continuity of material conveying. Moreover, the symmetrical design of the rotating blades 16 makes the material evenly stressed, reducing material retention in the conveying chamber 7 and adapting to the particle characteristics of silicon manganese iron nitride.

[0025] Reference Figure 1 , Figure 4 and Figure 5 The system includes a discharge pipe 13, whose top end is connected to the discharge end of the conveying chamber 7; a horizontal conveying pipe 8, whose inlet is connected to the discharge end of the discharge pipe 13; a first conveying rod 20, which is horizontally inserted inside the horizontal conveying pipe 8, with one end rotatably connected to the pipe wall of the horizontal conveying pipe 8 via a bearing; a first conveying auger 21, which is fixedly sleeved on the outer wall of the first conveying rod 20, with its blades in clearance fit with the inner wall of the horizontal conveying pipe 8, used to push the material to be conveyed horizontally; and a fourth motor 22, which is installed on the outer wall of one end of the horizontal conveying pipe 8, with its output end connected to the end of the first conveying rod 20. The fourth motor 22 (power 3kW, speed 960r / min) is fixed to the motor base on the outer wall of the horizontal conveying pipe 8 by bolts and is connected to the first conveying rod 20 via a rigid coupling.

[0026] Material enters the feed inlet of horizontal conveying pipe 8 from discharge pipe 13. The output end of fourth motor 22 drives the first conveying rod 20, which is horizontally installed inside the pipe, to rotate. The first conveying auger 21, which is sleeved on the outer wall of the conveying rod, rotates synchronously with the rod. Due to the gap fit between the auger blades and the inner wall of horizontal conveying pipe 8, the rotating blades will generate a spiral thrust, continuously pushing the material horizontally towards the discharge port of the conveying pipe, and finally sending it into inclined conveying pipe 9.

[0027] The conveying mechanism also includes an inclined conveying pipe 9, which is inclined upward and has its inlet connected to the outlet of the horizontal conveying pipe 8. A second conveying rod 10 is inclinedly inserted inside the inclined conveying pipe 9, with one end rotatably connected to the wall of the inclined conveying pipe 9 via a bearing. A second conveying auger 11 is fixedly sleeved on the outer wall of the second conveying rod 10, with its blades in clearance fit with the inner wall of the inclined conveying pipe 9 to push the material upward along the inclined direction. A second motor 12 is installed on the top outer wall of the inclined conveying pipe 9, with its output end connected to the end of the second conveying rod 10. A support plate 901 is provided on the bottom outer side of the inclined conveying pipe 9, with one end of the support plate 901 welded and fixed to the outer wall of the inclined conveying pipe 9. The second motor 12 (power 4kW, speed 750r / min) is fixed to the motor base on the outer wall of the inclined conveying pipe 9 by bolts and is connected to the second conveying rod 10 via a rigid coupling.

[0028] The material discharged from the horizontal conveying pipe 8 enters the feed inlet of the inclined conveying pipe 9. The output end of the second motor 12 drives the second conveying rod 10, which is inclined and passes through the pipe, to rotate. The second conveying auger 11, which is sleeved on the outer wall of the conveying rod, rotates with the rod. The auger blades are in clearance fit with the inner wall of the inclined conveying pipe 9. When rotating, it generates an upward spiral thrust, which overcomes the weight of the material and pushes the material upward along the inclined direction to the discharge end of the inclined pipe (which can be connected to subsequent equipment such as silos, mixers, etc.).

[0029] It enables horizontal and inclined upward conveying conversion to meet the material transfer needs at different heights in the workshop (such as feeding materials to high-level silos), and the clearance fit between the blades and the pipe wall can reduce material residue in the pipe, making it especially suitable for materials such as silicon manganese iron nitride that require precise measurement.

[0030] The implementation principle of the silicon nitride manganese iron mixture conveying device in this application embodiment is as follows: The feeding operator puts the silicon nitride manganese iron mixture into the inlet 4 of the feeding bin 1, and at the same time starts the first motor 2, which drives the rotating rod 3 and the deflector plate 17 to rotate. The deflector plate 17 continuously stirs the material, breaks up the clumps and pushes it to the discharge end of the feeding bin 1, so as to avoid the material from being stuck and blocked in the bin, and to provide a uniform material flow for subsequent conveying. The material discharged from the feed hopper 1 enters the hopper 601 through the corrugated telescopic feed pipe 603. The conical distribution column 19 in the hopper 601 first disperses the concentrated falling material 601 to the surrounding area, reducing the impact on the center of the hopper 601. Then, the vibration motor 602 is started to drive the hopper to vibrate vertically with a slight amplitude, so that the material is loosened and moves quickly towards the discharge end. The material first enters the conveying chamber 7. The third motor 14 drives the shaft 15 and the vane 16 to rotate, and pushes the material smoothly to the discharge pipe 13, realizing the transition connection between the unloading component and the horizontal conveyor. After the material enters the horizontal conveying pipe 8, the fourth motor 22 drives the first conveying auger 21 to rotate, and the material is conveyed horizontally to the inclined conveying pipe 9 by the spiral thrust. The second conveying auger 11 in the inclined conveying pipe 9, driven by the second motor 12, overcomes the weight of the material and pushes it upward in the inclined direction to the target position (such as a high-level silo or mixing equipment).
