Description

Technical Field

[0001] This utility model relates to the field of master alloy smelting technology, specifically a distributor for high-temperature alloy master alloy smelting. Background Technology

[0002] In the smelting of high-temperature alloy master alloys, the accuracy, anti-clogging properties, and purity of raw material distribution are crucial to the uniformity and performance of the master alloy composition. However, existing distribution equipment suffers from numerous problems: traditional distributors are prone to blockage due to lumpy raw materials and frequent clogging due to powder agglomeration, exhibiting poor adaptability and affecting efficiency; semi-automatic distributors rely on a single material control mode, resulting in low distribution accuracy and difficulty in meeting high tolerance requirements for element content, easily leading to compositional deviations and scrapping; atmospheric pressure distributors suffer from insufficient sealing, making raw materials susceptible to oxidation and contamination; some vacuum-adaptive distributors have poor sealing, affecting the purity of the master alloy; most distributors are single-hopper, single-channel designs, requiring frequent hopper switching during batch production, and involving a high proportion of manual operation, resulting in low efficiency, high labor intensity, and poor batch consistency. Therefore, those skilled in the art provide a distributor for high-temperature alloy master alloy smelting to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a distributor for high-temperature alloy master alloy smelting, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A distributor for smelting high-temperature alloy master alloys includes a centralized material pipe with hoppers fixedly connected to both ends. The upper surface of the hoppers has an inlet, which is connected to an external storage hopper. The outlet of the hoppers extends into the centralized material pipe, and a discharge shell is fixedly connected to the outlet of the centralized material pipe. A discharge hopper is fixedly connected to the outlet of the discharge shell, and a discharge port is provided at the bottom of the discharge hopper, which is connected to external smelting equipment.

[0006] Furthermore, a first bearing seat is fixedly connected to the side wall of the centralized material pipe, and a first rotating shaft is rotatably connected to the inner side wall of the first bearing seat.

[0007] Furthermore, a bidirectional spiral blade is fixedly connected to the surface of the first rotating shaft, and the bidirectional spiral blade abuts against the inner wall of the centralized material pipe.

[0008] Furthermore, a guide plate for guiding is fixedly connected to the inner side wall of the connecting hopper, and the pouring plate is inclined.

[0009] Furthermore, a first motor and a first reducer are fixedly connected to one end of the centralized material pipe. The power output end of the first motor is fixedly connected to the input end of the first reducer, and the output end of the first reducer is fixedly connected to the shaft end of the first rotating shaft.

[0010] Furthermore, a second bearing seat is fixedly connected to the side wall of the unloading housing, and a second rotating shaft is rotatably connected to the inner side wall of the second bearing seat. The second rotating shaft is located inside the unloading housing.

[0011] Furthermore, multiple sets of material-pushing plates are fixedly connected to the surface of the second rotating shaft. The material-pushing plates abut against the inner wall of the material feeding housing, and the cross-section of the material-pushing plates is in the shape of a cross.

[0012] Furthermore, a second motor and a second reducer are fixedly connected to the side wall of the feeding housing. The power output end of the second motor is fixedly connected to the input end of the second reducer, and the output end of the second reducer is fixedly connected to the shaft end of the second rotating shaft.

[0013] By adopting the above technical solution

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The centralized material pipe, connecting hopper and other components adopt a fixed and interconnected structure and can be made of corrosion-resistant materials to reduce the contact between raw materials and air, avoid cross-contamination, adapt to the vacuum smelting environment, and the bidirectional spiral blades support simultaneous feeding of multiple hoppers. The automated motor drive replaces manual labor, which greatly shortens the single furnace feeding time, reduces safety risks, adapts to the needs of large-scale smelting of high-temperature alloy master alloys, and improves production continuity and efficiency.

[0016] 2. The inclined guide plate inside the connecting hopper can prevent raw material accumulation during feeding. The bidirectional spiral blades of the centralized material pipe can scrape off residues on the pipe wall and are suitable for simultaneous feeding from multiple hoppers. The star-shaped material-distributing plate inside the discharge shell can break up lumpy raw materials and disperse powdered raw materials, effectively solving the clogging problem of traditional distributors. It is suitable for raw materials in multiple forms, including "lumpy + granular + powder". At the same time, its dual precision material control mechanism has outstanding effects. The first motor and reducer control the spiral blades to achieve "coarse adjustment" of the raw materials, while the second motor and reducer adjust the material-distributing plate to complete "fine adjustment". The dual speed regulation can effectively control the distribution accuracy and meet the needs of high-temperature alloy master alloys for precise addition of trace amounts of precious elements.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-4This utility model provides an embodiment of a distributor for high-temperature alloy master alloy smelting, including a centralized material pipe 1. Both ends of the centralized material pipe 1 are fixedly connected to hoppers 2. A feed inlet 5 is provided on the upper surface of the hopper 2, which is connected to an external storage hopper through the feed inlet 5. The outlet end of the hopper 2 extends into the centralized material pipe 1. A discharge housing 3 is fixedly connected to the outlet end of the centralized material pipe 1. A discharge hopper 4 is fixedly connected to the outlet end of the discharge housing 3. A discharge port 15 is provided at the bottom of the discharge hopper 4, which is connected to external smelting equipment through the bottom discharge port 15. A first bearing seat 6 is fixedly connected to the side wall of the centralized material pipe 1. A first rotating shaft 7 is rotatably connected to the inner wall of the bearing housing 6. A bidirectional spiral blade 8 is fixedly connected to the surface of the first rotating shaft 7, and the bidirectional spiral blade 8 abuts against the inner wall of the centralized material pipe 1. A guide plate 11 for guiding is fixedly connected to the inner wall of the connecting hopper 2, and the pouring plate is inclined. A first motor 10 and a first reducer 9 are fixedly connected to one end of the centralized material pipe 1. The power output end of the first motor 10 is fixedly connected to the input end of the first reducer 9, and the output end of the first reducer 9 is fixedly connected to the shaft end of the first rotating shaft 7. An external storage hopper (stores raw materials such as basic metal blocks, alloy element particles, or trace powders required for high-temperature alloy master alloys). The raw material is conveyed into the connecting hopper 2 through the feed inlet 5 on the upper surface of the connecting hopper 2. At this time, the inclined guide plate 11 inside the connecting hopper 2 plays a guiding role, preventing the raw material from accumulating on the inner wall of the hopper and guiding the raw material to slide smoothly into the centralized material pipe 1 along the inclined surface of the guide plate 11. The first motor 10 is started, and its power output end drives the first reducer 9 to run. After reduction and torque increase, it drives the first rotating shaft 7 to rotate in the centralized material pipe 1. The bidirectional spiral blades 8 fixed on the surface of the first rotating shaft 7 rotate synchronously with the rotating shaft. Because the bidirectional spiral blades 8 abut against the inner wall of the centralized material pipe 1, the raw material introduced into the connecting hoppers 2 at both ends can be gathered into the middle of the centralized material pipe 1. The spiral structure enables a conveying mode with feeding from both ends and centralized feeding in the middle. Simultaneously, by controlling the speed of the first motor 10 (which can be adjusted via an external PLC), the conveying speed of the spiral blades is precisely controlled, thereby achieving quantitative control of the raw material conveying volume. Components such as the centralized material pipe 1 and connecting hopper 2 adopt a fixed and interconnected structure and can be made of corrosion-resistant materials to reduce the contact between raw materials and air, avoid cross-contamination, and adapt to the vacuum smelting environment. Furthermore, the bidirectional spiral blades 8 support simultaneous feeding from multiple hoppers. Automated motor drive replaces manual labor, significantly shortening the single-furnace batching time, reducing safety risks, and adapting to the needs of large-scale smelting of high-temperature alloy master alloys, thereby improving production continuity and efficiency.

[0024] In this embodiment, a second bearing seat 12 is fixedly connected to the side wall of the feeding housing 3. A second rotating shaft 13 is rotatably connected to the inner side wall of the second bearing seat 12. The second rotating shaft 13 is located inside the feeding housing 3. Multiple sets of material-pulling plates 14 are fixedly connected to the surface of the second rotating shaft 13. The material-pulling plates 14 abut against the inner side wall of the feeding housing 3, and the cross-section of the material-pulling plates 14 is in the shape of a star. A second motor 17 and a second reducer 16 are fixedly connected to the side wall of the feeding housing 3. The power output end of the second motor 17 is fixedly connected to the input end of the second reducer 16, and the output end of the second reducer 16 is fixedly connected to the shaft end of the second rotating shaft 13. The raw material in the centralized material pipe 1 is pushed into the feeding housing 3, which is connected to its outlet end, by the bidirectional spiral blades 8. At this time, the second motor 17 is started, and its power is reduced by the second reducer 16, driving the second rotating shaft 13 to rotate inside the feeding housing 3. The multiple sets of star-shaped material-pulling plates 14 fixed to the surface of the second rotating shaft 13 rotate with the rotating shaft. Because the material-pulling plates 14 abut against the inner side wall of the feeding housing 3, they can... The raw materials entering the feeding shell 3 are evenly dispersed and pushed at a stable rate to the discharge hopper 4 connected to the outlet end of the feeding shell 3. Finally, the raw materials are accurately delivered to the external high-temperature alloy smelting equipment (such as vacuum induction furnace or electron beam cold hearth furnace) through the discharge port 15 at the bottom of the discharge hopper 4, completing a single raw material distribution process. The inclined guide plate 11 connected to the hopper 2 can prevent the raw material from accumulating. The bidirectional spiral blades 8 of the centralized material pipe 1 can scrape off the residue on the pipe wall and are suitable for simultaneous feeding of multiple material bins. The star-shaped material-dispersing plate 14 in the feeding shell 3 can disperse blocky raw materials and disperse powder raw materials, effectively solving the clogging problem of traditional distributors. It is suitable for raw materials of various forms such as "block + granules + powder". At the same time, its dual precision material control mechanism has outstanding effect. The first motor 10 and the reducer control the spiral blades to achieve "coarse adjustment" of the raw materials, and the second motor 17 and the reducer adjust the material-dispersing plate 14 to achieve "fine adjustment". The dual speed regulation can effectively control the distribution accuracy and meet the needs of high-temperature alloy master alloy for precise addition of trace precious elements.

[0025] The external storage hopper (which stores raw materials such as basic metal blocks, alloy element particles, or trace powders required for high-temperature alloy master alloys) conveys raw materials into the connecting hopper 2 through the feed inlet 5 on the upper surface of the connecting hopper 2. At this time, the inclined guide plate 11 inside the connecting hopper 2 plays a guiding role, preventing the raw materials from accumulating on the inner wall of the hopper and guiding the raw materials to slide smoothly into the centralized material pipe 1 along the inclined surface of the guide plate 11. The first motor 10 is started, and its power output end drives the first reducer 9 to run. After reduction and torque increase, it drives the first rotating shaft 7 to rotate in the centralized material pipe 1. The bidirectional spiral blades 8 fixed on the surface of the first rotating shaft 7 rotate synchronously with the rotating shaft. Because the bidirectional spiral blades 8 abut against the inner wall of the centralized material pipe 1, the raw materials introduced by the connecting hoppers 2 at both ends can be gathered in the middle of the centralized material pipe 1. The bidirectional spiral structure realizes the conveying mode of feeding from both ends and concentrating in the middle. At the same time, by controlling the speed of the first motor 10 (which can be adjusted by an external PLC), the spiral blades are precisely controlled. The conveying speed is adjusted to achieve quantitative control of the raw material conveying volume. The raw material in the centralized material pipe 1 is pushed by the bidirectional spiral blades 8 into the discharge shell 3 connected to its outlet end. At this time, the second motor 17 is started. Its power is reduced by the second reducer 16 and drives the second rotating shaft 13 to rotate in the discharge shell 3. Multiple sets of star-shaped material-pulling plates 14 fixed on the surface of the second rotating shaft 13 rotate with the shaft. Because the material-pulling plates 14 abut against the inner side wall of the discharge shell 3, the raw material entering the discharge shell 3 can be evenly dispersed and pushed to the discharge hopper 4 connected to the outlet end of the discharge shell 3 at a stable rate. Finally, the raw material is accurately conveyed to the external high-temperature alloy smelting equipment (such as vacuum induction furnace, electron beam cold hearth furnace) through the discharge port 15 at the bottom of the discharge hopper 4, completing a single raw material distribution process. In the whole process, the first motor 10 and the second motor 17 can be independently adjusted to control the "centralized conveying volume" and "discharge rate" respectively, realizing dual precise control of raw material distribution.

[0026] The centralized feed pipe 1, connecting hopper 2, and other components adopt a fixed and interconnected structure and can be made of corrosion-resistant materials, reducing the contact between raw materials and air, avoiding cross-contamination, and adapting to vacuum smelting environments. The bidirectional spiral blades 8 support simultaneous feeding from multiple hoppers, and the automated motor drive replaces manual labor, significantly shortening the single-furnace batching time, reducing safety risks, and meeting the needs of large-scale smelting of high-temperature alloy master alloys, improving production continuity and efficiency. The inclined guide plate 11 inside the connecting hopper 2 can prevent raw material accumulation, and the bidirectional spiral blades 8 of the centralized feed pipe 1 can scrape off residues from the pipe wall. It is compatible with simultaneous feeding from multiple hoppers. The cross-shaped material feeding plate 14 inside the feeding shell 3 can break up blocky raw materials and disperse powdery raw materials, effectively solving the clogging problem of traditional distributors. It is compatible with raw materials in multiple forms such as "block + granules + powder". At the same time, its dual precision material control mechanism has outstanding effect. The first motor 10 and the reducer control the spiral blade to achieve "coarse adjustment" of raw materials, while the second motor 17 and the reducer adjust the material feeding plate 14 to complete "fine adjustment". The dual speed regulation can effectively control the distribution accuracy and meet the needs of high-temperature alloy master alloy for precise addition of trace precious elements.
