Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic furnace feeding equipment, specifically to a multifunctional electrolytic furnace feeding machine. Background Technology

[0002] In the electrolytic preparation of rare earth metals and their alloys, the rare earth electrolytic furnace is the core production equipment. This process is usually carried out in a high-temperature, closed or inert gas protected environment, and has extremely high requirements for the addition of raw materials (such as rare earth oxides, fluoride salts, etc.). It is necessary to ensure the accuracy, sealing and regularity of the feeding to maintain the stability of the electrolyte composition and the quality of the metal products.

[0003] Currently, the common feeding method used in rare earth electrolysis workshops is to equip each electrolysis furnace with a dedicated feeder, forming a fixed configuration of "one furnace per machine". For example, a rare earth electrolysis feeder and feeding method disclosed in publication number CN113061940A includes a vacuum feeding system, a weighing feeding system, and a discharging system connected in sequence. The vacuum feeding system includes a sealed feeding pipe, an air pump, and a raw material silo, as well as a feeding control module. A pneumatic butterfly valve, a flexible connector, and a first weighing device are arranged in sequence between the vacuum feeding system and the weighing feeding system. A support is provided around the outer periphery of the raw material silo. The weighing feeding system includes a feeding silo, a second weighing device, and a feeding device, as well as a weighing controller.

[0004] However, existing rare earth electrolysis production has two significant characteristics: First, the scale of a single electrolysis furnace is relatively small, but the layout within the workshop is dense; second, the requirements for the cleanliness and sealing of the production environment are extremely high, leading to the following urgent technical defects exposed in the existing "one machine, one furnace" model: 1. The cost-effectiveness issue is extremely prominent: Rare earth electrolysis workshops usually need to operate dozens or even hundreds of small electrolysis furnaces simultaneously to achieve large-scale production. If each furnace is equipped with an independent automated feeding system, the cost of equipment procurement, installation and subsequent maintenance will constitute an extremely heavy economic burden.

[0005] 2. Severe spatial conflicts and operational interference: The dense furnace layout already makes workshop space extremely valuable. The fixed installation of a feeding machine for each furnace results in a dense array of equipment and narrow passageways. This not only greatly hinders operators from carrying out daily operations such as metal tapping, slag removal, temperature measurement, and equipment maintenance, but also poses significant safety risks.

[0006] 3. Low equipment utilization and maintenance difficulties: The feeding of rare earth electrolysis furnaces is a short-term, high-frequency intermittent operation. A feeding machine is idle for a long time, but the space it occupies and the cost invested are completely fixed, resulting in a huge waste of capital and space resources. Utility Model Content

[0007] To address the technical problems existing in the background art, this utility model proposes a multifunctional electrolytic furnace feeder.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: A multifunctional electrolytic furnace feeder includes a frame, a feeding tank assembly for storing raw materials, a receiving module for weighing and transferring raw materials, a transverse unit for driving the receiving module to move, and a discharge pipe assembly for discharging materials. The lateral movement unit drives the transfer part of the receiving module to move so that the receiving module has at least a first tilting discharge position and a second tilting discharge position. The discharge pipe group includes at least a first discharge pipe and a second discharge pipe. The first discharge pipe is located below the first tilting discharge position, and the second discharge pipe is located below the second tilting discharge position.

[0009] Preferably, the feeding tank group includes at least a first feeding tank for storing oxides and a second feeding tank for storing electrolytes. Through the above improvements, a flexible feeding function that can adapt to multiple raw materials and multiple electrolytic furnaces at the same time is realized, which significantly reduces the number of equipment and the floor space, improves the utilization rate of a single machine and the feeding accuracy, and effectively solves the problems of high cost, crowded layout and serious waste of resources in traditional feeding systems.

[0010] Preferably, the receiving module includes a first transfer component for receiving oxides and a second transfer component for receiving electrolytes. The first and second transfer components include a receiving section for receiving raw materials and a transfer section for weighing and pouring raw materials. The raw materials are transported from the receiving section to the transfer section and poured into the discharge pipe group through the transfer section. The transfer section is set on a transverse moving unit. Through the above improvements, the independent receiving, accurate weighing, and separate transportation of oxides and electrolytes are realized, effectively avoiding cross-contamination. A single device can complete the flexible feeding of multiple raw materials to multiple electrolytic furnaces, significantly improving the feeding accuracy and the overall utilization efficiency of the equipment, and reducing the operation and maintenance costs.

[0011] Preferably, the receiving section includes a vibration unit mounted on the frame and a receiving channel mounted on the vibration unit. The output end of the receiving channel is located above the transfer section. Through the above improvements, the vibration unit can effectively promote the flow of materials in the receiving channel, prevent oxides and electrolytes from clogging during the conveying process, and ensure the continuity and stability of feeding.

[0012] Preferably, the transfer unit includes a weighing unit and a transfer hopper mounted on the weighing unit. The transfer hopper is provided with an elastic element, one end of which abuts against the transfer hopper and the other end against the weighing unit, so that the transfer hopper always has a tendency to rotate toward the weighing unit. The transfer unit is also provided with a tilting unit that drives the transfer hopper to rotate. With the above improvements, when the raw material falls into the transfer hopper, the weighing unit can accurately measure the weight of the raw material. When the specified weight is reached, the tilting unit will drive the transfer hopper to rotate to discharge the material. After the material is discharged, the transfer hopper will automatically reset under the action of the elastic element.

[0013] Preferably, a first screening plate is provided in the receiving channel, and an adjusting screw is provided on the frame to drive the first screening plate to move up and down. A second screening plate is provided at the output end of the receiving channel, and a lifting unit is provided on the frame to drive the second screening plate to move up and down. Screening troughs are formed on the first and second screening plates. Through the above improvements, precise control and effective screening of raw material flow are achieved. The first screening plate can perform preliminary sorting of the material, while the second screening plate precisely controls the feeding speed at the outlet. This dual adjustment mechanism effectively prevents material blockage and sloshing, ensuring uniform, stable and controllable feeding, thereby significantly improving the accuracy and reliability of the entire feeding system.

[0014] Preferably, the frame is provided with a receiving frame, and the discharge pipe assembly is inserted into the receiving frame. Through the above improvements, the receiving frame can receive raw materials scattered outside, reducing on-site loss of raw materials and dust pollution, and improving the workshop working environment.

[0015] Preferably, the receiving frame is designed to converge towards the center, and a recycling tank is located at the center of the receiving frame. Through the above improvements, dust collection is achieved, thereby improving the workshop environment.

[0016] Preferably, the moving end of the transverse unit is provided with a guide cover, the inside of which forms a material dropping channel, and the side of the guide cover forms a feed inlet that connects to the discharge channel. The discharge end of the transfer hopper is placed inside the feed inlet. Through the above improvements, the guide cover forms a closed material dropping space between the transfer hopper and the discharge channel, which can effectively prevent the dust generated during the pouring process from escaping, and at the same time accurately guide the material into the target discharge pipe.

[0017] Preferably, the first and second feeding tanks each include a tank body that tapers radially from the bottom. The tank body includes a first contracting portion and a second contracting portion that are joined together. The first inclination angle formed by the generatrix of the first contracting portion and the central axis of the tank body is α, and the second inclination angle formed by the generatrix of the second contracting portion and the central axis of the tank body is β. The first inclination angle α is not equal to the second inclination angle β. Through the above improvements, the material feeding is smoother, and the jamming situation is avoided.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects: The integrated design enables efficient and precise feeding operations: First, the receiving module receives and weighs the raw materials from the feeding tank group; then, the traverse unit drives its movement, allowing it to be precisely positioned at the first or second tilting discharge position; finally, the raw materials are fed into different electrolytic furnaces through the corresponding first or second discharge pipes. Compared with existing technologies, this design achieves a breakthrough of one machine serving multiple furnaces, significantly improving operating efficiency and avoiding the time-consuming process of equipping each furnace with independent equipment or waiting for the overhead crane. Its compact structure optimizes the space layout and significantly reduces equipment and maintenance costs. Automated and precise control ensures process stability and overall reliability, making it particularly suitable for modern, high-density production lines. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0022] like Figure 1-6 As shown, a multi-functional electrolytic furnace feeder includes a frame 1, a feeding tank group 2 for storing raw materials, a receiving module 3 for weighing and transferring raw materials, a transverse moving unit 4 for driving the receiving module 3 to move, and a discharge pipe group 5 for discharging materials. Specifically, the transverse unit 4 drives the transfer part of the receiving module 3 to move so that the receiving module 3 has at least a first tilting discharge position and a second tilting discharge position. The discharge pipe group 5 includes at least a first discharge pipe 1.1 and a second discharge pipe 1.2. The first discharge pipe 1.1 is located below the first tilting discharge position, and the second discharge pipe 1.2 is located below the second tilting discharge position.

[0023] The receiving module 3 receives and weighs the raw materials from the feeding tank group 2. The transverse unit 4 drives its movement, allowing it to be precisely positioned at the first or second tilting discharge position. The raw materials are then fed into different electrolytic furnaces through the corresponding first or second discharge pipes 1.2. Compared with existing technologies, this design achieves a breakthrough of one machine serving multiple furnaces, significantly improving operating efficiency and avoiding the time-consuming process of equipping each furnace with independent equipment or waiting for the overhead crane. Its compact structure optimizes the spatial layout and significantly reduces equipment and maintenance costs. Automated and precise control ensures process stability and overall reliability, making it particularly suitable for modern, dense production lines.

[0024] like Figure 1 , Figure 2 , Figure 6 As shown in the further explanation of the implementation of the feeding tank group 2 in this embodiment, the feeding tank group 2 includes at least a first feeding tank 1.3 for storing oxides and a second feeding tank 1.4 for storing electrolytes. It realizes the flexible feeding function of one machine adapting to multiple raw materials and multiple electrolytic furnaces at the same time, which significantly reduces the number of equipment and the floor space, improves the utilization rate of single machine and feeding accuracy, and effectively solves the problems of high cost, crowded layout and serious waste of resources in traditional feeding systems.

[0025] Of course, the feeding tank group 2 is not limited to the first feeding tank 1.3 and the second feeding tank 1.4. Multiple feeding tanks can be set up to achieve the supply of multiple raw materials.

[0026] Furthermore, the first feeding tank 1.3 and the second feeding tank 1.4 include a tank body 6.1, which tapers radially along its bottom. The tank body 6.1 includes a first contracting section 6.2 and a second contracting section 6.3. The first inclination angle formed by the generatrix of the first contracting section 6.2 and the central axis of the tank body 6.1 is α, and the second inclination angle formed by the generatrix of the second contracting section 6.3 and the central axis of the tank body 6.1 is β. The first inclination angle α is not equal to the second inclination angle β, which makes the bottom of the tank form a unique flow channel with directional guiding function. Under the action of its own gravity, the material will naturally and quickly converge from the steeper contracting section (assuming α > β) to the gentler contracting section and be guided to the discharge port, creating a "tangential sliding" flow effect, making the raw material fall more smoothly and avoiding material jamming.

[0027] like Figure 1 , Figure 3 , Figure 4As a further explanation of the embodiment of the receiving module 3, the receiving module 3 includes a first transfer component 1.5 for receiving oxides and a second transfer component 1.6 for receiving electrolytes. The first transfer component 1.5 and the second transfer component 1.6 include a receiving section 2.1 for receiving raw materials and a transfer section 2.2 for weighing and pouring the raw materials. The raw materials are conveyed from the receiving section 2.1 to the transfer section 2.2 and poured into the discharge pipe assembly 5 through the transfer section 2.2. The transfer section 2.2 is provided on the transverse movement unit 4. Two transverse units 4 are installed on the frame 1, which drive the transfer unit 2.2 to move. The transfer unit 2.2 slides between the first tilting discharge position and the second tilting discharge position to discharge materials from the first discharge pipe 1.1 and the second discharge pipe respectively. This realizes the independent reception, accurate weighing and separate transportation of two types of materials, oxides and electrolytes, effectively avoiding cross-contamination. A single device can complete the flexible feeding of multiple raw materials to multiple electrolytic furnaces, significantly improving the feeding accuracy and the overall utilization efficiency of the equipment, and reducing the operation and maintenance costs.

[0028] Among them, the transverse unit 4, the receiving part 2.1, and the transfer part 2.2 can be adjusted according to the number of feeding tanks, so as to meet the needs of conveying various raw materials.

[0029] Specifically, the receiving section 2.1 includes a vibration unit 3.1 mounted on the frame 1 and a receiving channel 3.2 mounted on the vibration unit 3.1. The output end of the receiving channel 3.2 is located above the transfer section 2.2. The vibration unit 3.1 can effectively promote the flow of materials in the receiving channel 3.2, prevent oxides and electrolytes from clogging during the conveying process, and ensure the continuity and stability of the feeding.

[0030] Furthermore, the transfer unit 2.2 includes a weighing unit 3.3 and a transfer hopper 3.4 mounted on the weighing unit 3.3. An elastic element 3.5 is provided on the transfer hopper 3.4, with one end of the elastic element 3.5 abutting against the transfer hopper 3.4 and the other end abutting against the weighing unit 3.3, so that the transfer hopper 3.4 always has a tendency to rotate toward the weighing unit 3.3. The transfer unit 2.2 is also provided with a tilting unit 3.6 that drives the transfer hopper to rotate. When the raw material falls into the transfer hopper 3.4, the weighing unit 3.3 can accurately measure the weight of the raw material. When the specified weight is reached, the tilting unit 3.6 will drive the transfer hopper 3.4 to rotate to discharge the material. After the material is discharged, the transfer hopper 3.4 will automatically reset under the action of the elastic element 3.5.

[0031] Preferably, a first screening plate 4.1 is provided in the receiving channel 3.2, and an adjusting screw 4.2 is provided on the frame 1 to drive the first screening plate 4.1 to move up and down. A second screening plate 4.3 is provided at the output end of the receiving channel 3.2, and a lifting unit 4.4 is provided on the frame 1 to drive the second screening plate 4.3 to move up and down. Screening troughs 4.5 are formed on the first screening plate 4.1 and the second screening plate 4.3, realizing precise control and effective screening of raw material flow. The first screening plate 4.1 can perform preliminary sorting of materials, while the second screening plate 4.3 precisely controls the feeding speed at the outlet. This dual adjustment mechanism effectively prevents material blockage and sloshing, ensuring uniform, stable and controllable feeding, thereby significantly improving the accuracy and reliability of the entire feeding system.

[0032] Preferably, the moving end of the transverse unit 4 is provided with a guide cover 5.1, which forms a material dropping channel 5.2. The side of the guide cover 5.1 forms an inlet 5.3 that connects to the discharge channel. The discharge end of the transfer hopper 3.4 is placed in the inlet 5.3. The guide cover 5.1 forms a closed material dropping space between the transfer hopper 3.4 and the discharge channel, which can effectively prevent the dust generated during the pouring process from escaping, and at the same time accurately guide the material into the target discharge pipe.

[0033] like Figure 1 , Figure 5 As shown, as a further explanation of the implementation method of the discharge pipe group 5, the number of discharge pipes needs to be set according to the number of corresponding electrolytic furnaces to realize one machine corresponding to multiple electrolytic furnaces.

[0034] Specifically, a receiving frame 4.6 is provided on the frame 1. The receiving frame 4.6 is located below the receiving module 3, and the discharge pipe group 5 is inserted into the receiving frame 4.6. The receiving frame 4.6 can receive raw materials scattered outside and can collect dust generated during the falling process of the raw materials, reducing on-site loss of raw materials and dust pollution, and improving the workshop working environment.

[0035] Furthermore, the receiving frame 4.6 is designed to taper towards the center, and a recycling tank 4.7 is located at the center of the receiving frame 4.6. The recycling tank 4.7 can collect the dust generated during the falling of raw materials, which not only improves the working environment of the workshop, but also enhances the convenience of cleaning the receiving frame 4.6.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
