Description

Technical Field

[0001] This utility model relates to the technical field of high-titanium slag smelting equipment, specifically to a furnace top feeding device for uniformly distributing materials in high-titanium slag smelting. Background Technology

[0002] High-titanium slag is a key raw material in the titanium industry, and its smelting process requires extremely high uniformity in raw material distribution—the distribution of raw materials within the smelting furnace directly affects the stability of the furnace temperature field, the reaction rate of the raw materials, and the quality of the final product. Currently, the furnace top feeding devices commonly used in the industry for high-titanium slag smelting mostly adopt fixed chutes or simple feed pipe structures. These devices have significant technical defects:

[0003] On the one hand, the fixed structure makes it impossible to adjust the direction of the material feeding, and the raw materials are prone to local accumulation in the furnace. This leads to over-melting of the raw materials in the accumulated areas due to excessive heating, while the empty areas waste heat due to insufficient raw materials. This not only reduces smelting efficiency but also easily produces inferior high-titanium slag with uneven composition, increasing subsequent purification costs. On the other hand, high-titanium slag raw materials often agglomerate and clump due to differences in particle size or the presence of trace amounts of moisture. Traditional feeding devices lack pretreatment structures, and agglomerated raw materials can easily block the feeding channel, causing feeding interruptions. This requires manual shutdown for cleaning, which seriously affects the continuity of production. In addition, there is a safety hazard of high-temperature burns during the cleaning process.

[0004] In view of this, we propose a furnace top feeding device with uniform material distribution for high-titanium slag smelting. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a furnace top feeding device for uniformly distributing materials in high-titanium slag smelting.

[0006] The technical solution of this utility model is:

[0007] A furnace top feeding device for uniformly distributing high-titanium slag in smelting includes a feeding hopper. The bottom of the feeding hopper has an integrally formed flat downward extending plate that extends into the smelting furnace. The bottom of the downward extending plate is connected to a swing plate via a corrugated pipe. The swing plate, corrugated pipe, and downward extending plate are all hollow. A side plate is fixed to each side of the downward extending plate, extending downward to both sides of the swing plate. The swing plate is rotatably mounted between the two side plates. An adjusting motor with an output shaft fixedly connected to the swing plate is installed on one of the side plates. By setting a flat downward extending plate at the bottom of the feeding hopper, combined with a swing plate connected by a corrugated pipe, and using an adjusting motor to drive the swing plate to rotate between the two side plates, a swinging distribution of high-titanium slag raw material in the smelting furnace is achieved. The angle adjustment of the swing plate can evenly distribute the raw material to different areas in the furnace, avoiding local accumulation and improving the heating uniformity and reaction efficiency of the raw material during smelting. The structure is simple, and the distribution range can be flexibly controlled by the swing angle.

[0008] As a preferred technical solution, a fixing plate is fixedly connected to the outer wall of the lower extension plate. An annular support frame is integrally formed at the bottom of the fixing plate, and the support frame is provided with a plurality of fixing bolts arranged in a circular array. The fixing plate and the annular support frame provide a stable installation foundation for the entire feeding device, and the circularly arrayed fixing bolts can firmly fix the device to the top of the smelting furnace, ensuring the overall stability of the device during the feeding process.

[0009] It should be noted that the fixing bolts are only used to increase the stability of the entire device during feeding. After feeding is completed, the entire device needs to be disassembled from above the smelting furnace to avoid damage to the regulating motor and bellows during high-temperature smelting.

[0010] As a preferred technical solution, the support frame has an L-shaped cross-section, and the fixing bolts are located between the support frame and the fixing plate. The L-shaped support frame and the fixing plate cooperate to form a stable load-bearing structure, and the fixing bolts located between the two can enhance the connection strength, making the support frame more stable in supporting the device.

[0011] As a preferred technical solution, the top of the feeding hopper is integrally formed with an L-shaped mounting frame, on which a stirring mechanism extending into the feeding hopper is mounted. The L-shaped mounting frame at the top of the feeding hopper provides a stable mounting point for the stirring mechanism. The stirring mechanism extending into the feeding hopper can stir the high-titanium slag raw material, preventing the raw material from clumping or clogging in the feeding hopper, ensuring that the raw material can continuously and smoothly enter the lower extension plate and swing plate, avoiding interruptions or uneven material distribution due to blockage, and improving the continuity and stability of feeding.

[0012] As a preferred technical solution, the stirring mechanism includes a stirring shaft rotatably mounted at the bottom of the mounting frame, with a plurality of stirring blades fixed on the outer circumference of the stirring shaft, and a stirring motor with an output shaft coaxially fixed to the stirring shaft mounted on the top of the mounting frame. The stirring motor drives the stirring shaft and stirring blades to rotate, and the stirring blades mechanically stir the raw materials in the feeding hopper, which can break up the agglomeration of the raw materials and make the raw material particles more evenly distributed.

[0013] As a preferred technical solution, the end of the stirring blade away from the stirring shaft is close to the inner ring wall of the feeding hopper. This allows for thorough stirring of the raw materials near the inner wall of the feeding hopper, preventing the raw materials from accumulating on the wall and forming dead corners.

[0014] As a preferred technical solution, the swing angle of the swing plate is between -75° and 75°. This ensures a sufficiently large material coverage area, allowing the raw materials to be evenly distributed over a large area of ​​the furnace, while also ensuring that the materials fall under the influence of gravity.

[0015] As a preferred technical solution, the bellows is not stretched to its maximum length during the swinging process of the swing plate. This allows for a certain amount of expansion and contraction of the bellows, preventing fatigue damage or breakage due to excessive stretching during swinging, thus ensuring the sealing performance and service life of the bellows.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention achieves the oscillating distribution of high-titanium slag raw materials in the smelting furnace by setting a flat downward extension plate at the bottom of the feeding hopper, combined with a swaying plate connected by a corrugated pipe, and using an adjustable motor to drive the swaying plate to rotate between the two side plates. The angle adjustment of the swaying plate can evenly distribute the raw materials to different areas in the furnace, avoid local accumulation, improve the heating uniformity and reaction efficiency of the raw materials during the smelting process, and has a simple structure and the distribution range can be flexibly controlled by the swaying angle.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A furnace top feeding device for uniformly distributed material in high-titanium slag smelting includes a feeding hopper 1. The bottom of the feeding hopper 1 is integrally formed with a flat lower extension plate 4. The bottom of the lower extension plate 4 extends into the smelting furnace. The bottom of the lower extension plate 4 is connected to a swing plate 3 through a corrugated pipe 5. The swing plate 3, the corrugated pipe 5 and the lower extension plate 4 are all hollow. A side plate 40 is fixed on both sides of the lower extension plate 4. The side plates 40 extend downward to both sides of the swing plate 3, and the swing plate 3 is rotatably installed between the two side plates 40. An adjusting motor 41 with an output shaft fixedly connected to the swing plate 3 is installed on one of the side plates 40. By setting a flat downward extension plate 4 at the bottom of the feeding hopper 1, combined with a swing plate 3 connected by a corrugated pipe 5, and using an adjusting motor 41 to drive the swing plate 3 to rotate between the two side plates 40, the high-titanium slag raw material is oscillating and distributed in the smelting furnace. The angle adjustment of the swing plate 3 can evenly distribute the raw material to different areas in the furnace, avoid local accumulation, improve the heating uniformity and reaction efficiency of the raw material during the smelting process, and the structure is simple and the distribution range can be flexibly controlled by the swing angle.

[0027] In a preferred embodiment, a fixing plate 2 is fixedly connected to the outer wall of the lower extension plate 4. An annular support frame 20 is integrally formed at the bottom of the fixing plate 2, and the support frame 20 is provided with a plurality of fixing bolts 21 arranged in a circular array. The fixing plate 2 and the annular support frame 20 provide a stable installation foundation for the entire feeding device, and the circularly arrayed fixing bolts 21 can firmly fix the device to the top of the smelting furnace, ensuring the overall stability of the device during the feeding process.

[0028] It should be noted that the fixing bolt 21 is only used to increase the stability of the entire device during feeding. After feeding is completed, the entire device needs to be disassembled from above the smelting furnace to avoid damage to the regulating motor 41 and the bellows 5 during high-temperature smelting.

[0029] In a preferred embodiment, the support frame 20 has an L-shaped cross-section, and the fixing bolt 21 is located between the support frame 20 and the fixing plate 2. The L-shaped support frame 20 and the fixing plate 2 cooperate to form a stable load-bearing structure, and the fixing bolt 21 located between the two can enhance the connection strength, making the support frame 20 more stable in supporting the device.

[0030] In a preferred embodiment, the top of the feeding hopper 1 is integrally formed with an L-shaped mounting bracket 10, on which a stirring mechanism extending into the feeding hopper 1 is mounted. The L-shaped mounting bracket 10 at the top of the feeding hopper 1 provides a stable mounting point for the stirring mechanism. The stirring mechanism extending into the feeding hopper 1 can stir the high-titanium slag raw material, preventing the raw material from clumping or clogging in the feeding hopper 1, ensuring that the raw material can continuously and smoothly enter the lower extension plate 4 and the swing plate 3, avoiding interruption or uneven feeding due to blockage, and improving the continuity and stability of feeding.

[0031] In a preferred embodiment, the stirring mechanism includes a stirring shaft 12 rotatably mounted at the bottom of the mounting frame 10, with a plurality of stirring blades 13 fixed on the outer circumference of the stirring shaft 12. A stirring motor 11, with its output shaft coaxially fixed to the stirring shaft 12, is mounted on the top of the mounting frame 10. The stirring motor 11 drives the stirring shaft 12 and the stirring blades 13 to rotate, thereby mechanically stirring the raw materials in the feeding hopper 1 through the stirring blades 13. This breaks up the agglomeration of the raw materials and makes the particle distribution of the raw materials more uniform.

[0032] As a preferred embodiment, the end of the stirring blade 13 furthest from the stirring shaft 12 is close to the inner annular wall of the feeding hopper 1. This allows for thorough stirring of the raw materials near the inner wall of the feeding hopper 1, preventing the accumulation of raw materials on the wall surface and the formation of dead zones.

[0033] As a preferred embodiment, the swing angle of the swing plate 3 is between -75° and 75°. This ensures a sufficiently large coverage area for the material to be evenly distributed throughout a large area of ​​the furnace, while also ensuring that the material falls under the influence of gravity.

[0034] As a preferred embodiment, the bellows 5 is not stretched to its maximum length during the swinging process of the swing plate 3. A margin for expansion and contraction of the bellows 5 is reserved to prevent fatigue damage or breakage due to excessive stretching during swinging, thus ensuring the sealing performance and service life of the bellows 5.

[0035] In use, the furnace top feeding device for uniform material distribution in high-titanium slag smelting of this utility model is first securely installed on the furnace top using the L-shaped annular support frame 20 and circular array fixing bolts 21 at the bottom of the fixing plate 2 on the outer wall of the lower extension plate 4. After startup, high-titanium slag raw material is added. The stirring motor 11 of the stirring mechanism at the top of the feeding hopper 1 drives the stirring shaft 12 and stirring blades 13 to rotate. The stirring blades 13 are close to the hopper wall to prevent the raw material from clumping and blocking, ensuring that the raw material flows smoothly to the bottom flat lower extension plate 4. The raw material enters the hollow swing plate 3 connected by the corrugated pipe 5 through the lower extension plate 4. The motor 41 is adjusted to drive the swing plate 3 to rotate between -75° and 75° to achieve uniform material distribution in the furnace. The corrugated pipe 5 is reserved with expansion and contraction margin to avoid damage. After the feeding is completed, the device is removed to prevent high temperature damage to the motor and corrugated pipe 5 and to ensure subsequent use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
