Description

Technical Field

[0001] This utility model belongs to the technical field of alloy smelting feeding devices, specifically relating to an induction smelting feeding device for nickel alloy production. Background Technology

[0002] Nickel alloys are alloys formed by adding other elements to nickel. Nickel has good mechanical, physical, and chemical properties, and appropriate elements can be added to improve its oxidation resistance, corrosion resistance, high-temperature strength, and certain physical properties. Induction melting is a production process for nickel alloys, and the smoothness and precision of the feeding process directly affect melting efficiency, alloy composition uniformity, and final quality.

[0003] Nickel alloys are made from a variety of raw materials, mostly in the form of blocks, scraps, and recycled materials. When these materials fall into the feeding hopper, they overlap due to their irregular shapes and varying sizes, creating an "arch bridge" effect that blocks the feeding channel and causes production to be interrupted. In severe cases, operators need to stop using the hopper and manually clear the blockage, which is labor-intensive, inefficient, and also poses safety hazards in the high-temperature smelting environment.

[0004] Existing mechanical feeding devices are basically fixed at a fixed angle, or can only be coarsely adjusted for very small amounts of molten metal. However, different models and capacities of induction melting furnaces have different feed inlet positions and heights. Fixed-angle feeding devices cannot flexibly adjust the feeding path according to the actual situation on site. Not only will the material not fall accurately into the center of the furnace, but it will also impact the furnace lining or splash molten metal, resulting in a reduction in the service life of the furnace lining and an increase in safety risks.

[0005] There is an urgent need for a new type of feeding device that can prevent material blockage, flexibly adjust the feeding angle, and be quickly and stably installed on the smelting furnace body. Therefore, a feeding device for induction melting of nickel alloy production is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a feeding device for induction melting of nickel alloys, which has the functions of anti-clogging, adjustable feeding angle and quick and stable installation. It solves the problems of easy blockage of materials at the feeding port, inability to fix the feeding trajectory, and the complexity and bulkiness of traditional installation methods, which cannot be quickly integrated and fixed with the furnace body.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a feeding device for induction melting of nickel alloy production, including an L-shaped plate. A drive motor is provided on the rear side of the L-shaped plate. The drive motor is fixed to the vertical arm of the L-shaped plate by bolts.

A U-shaped slot with a downward opening is provided at the bottom of the support base. Insertion holes are provided on one side of the support base and the outer surface of the semi-circular block. Fixing bolts are inserted into the insertion holes.

[0008] Preferably, the shell has a Π-shaped cross section, an insert block is provided at the bottom of the shell, and a slot is provided on the cross arm of the L-shaped plate.

[0009] Preferably, the stirring shaft is arranged perpendicular to the vertical arm of the L-shaped plate, and the cutting teeth have a spiral structure.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, such as Figure 1-3 As shown, a feeding device for induction melting in nickel alloy production includes an L-shaped plate 1, which serves as the structural frame for load-bearing and connecting and fixing other components. A drive motor 2 is installed on the rear side of the L-shaped plate 1, and the drive motor 2 is fixed to the vertical arm of the L-shaped plate 1 by bolts 3. A housing 4 is installed at the top of the horizontal arm of the L-shaped plate 1, and the bolts 3 are used for fixing. The housing 4 constitutes a material collection, guiding and conveying channel, which facilitates the smooth discharge of materials and is easy to clean and maintain. A stirring shaft 5 is installed at the front end of the drive motor 2, and the stirring shaft 5 is equipped with cutting teeth 6. The drive motor 2 provides power and transmits torque through the stirring shaft 5 to drive the cutting teeth 6 to rotate, thereby stirring, crushing and guiding the falling materials.

[0020] A feeding hopper 7 is located at the top of the shell 4. The feeding hopper 7 is used for adding material, and a top cover 8 is located at the top of the feeding hopper 7 to close it. A semi-circular block 9 is located at the bottom of the cross arm of the L-shaped plate 1. A support base 10 is fitted onto the semi-circular block 9. The bottom of the support base 10 has a downward-opening U-shaped slot 11, which allows for quick connection and stable support to the smelting furnace. The U-shaped slot 11 is directly embedded into the plate-like structure at the top of the side wall of the smelting furnace, such as a platform upright or reinforcing rib, without any welding or bolt connection, enabling quick installation. Insertion holes are provided on one side of the support base 10 and the outer surface of the semi-circular block 9, and fixing bolts 12 are inserted into the insertion holes. The semi-circular block 9 and the fixing bolts 12 together constitute a simple angle adjustment and locking mechanism. By inserting the fixing bolts 12 into the insertion holes at different angles on the semi-circular block 9, the feeding angle can be adjusted in multiple positions to accommodate the feed inlet of the smelting furnace at different heights. To achieve more precise stepless adjustment, this part can be upgraded to a gear and rack mechanism with a locking handle or an arc groove and wing nut mechanism, making angle adjustment more continuous, precise and easier to operate.

[0021] The specific design of the aforementioned key components will be discussed in detail below: The shell 4 has a Π-shaped cross-section, with insert blocks 13 at its bottom and slots on the crossarm of the L-shaped plate 1. The shell 4 is welded from heat-resistant steel plates, with a Π-shaped cross-section, meaning it is closed at the top, extends downwards on both sides, and has an open bottom. At least two strip-shaped insert blocks 13 are symmetrically welded to the two sides of the bottom of the shell 4. Correspondingly, on the top surface of the crossarm of the L-shaped plate 1, slots with Π-shaped structures that match the position, shape, and size of the insert blocks 13 are machined, forming a three-sided enclosed flow channel that effectively guides materials. The insert blocks 13 are installed by aligning them with the slots on the L-shaped plate 1 and inserting them from top to bottom to complete positioning and fixation, achieving modularity of the shell 4. This facilitates quick and thorough cleaning of the interior of the shell 4 and the stirring shaft 5 when changing alloy types or performing regular maintenance.

[0022] The stirring shaft 5 is perpendicular to the vertical arm of the L-shaped plate 1, and the cutting teeth 6 are helical. The stirring shaft 5 is directly connected to the output shaft of the drive motor 2 via a coupling, and the axis is perpendicular to the plane of the vertical arm of the L-shaped plate 1, ensuring direct and efficient power transmission. The cutting teeth 6 are single-headed helical structures, continuously welded and fixed to the stirring shaft 5, with a helix angle preferably between 15° and 45°. The helical cutting teeth 6 not only cut, but also utilize the continuous propulsion unique to helical lines to shred arched materials, generating a continuous, forward axial conveying force, breaking up the arch and forcing the materials to fall smoothly, thus solving the problems of jamming and insufficient pushing force of simple blade cutting.

[0023] The top cover 8 is hinged to one side of the top of the feeding hopper 7 via a hinge 16, and a handle 14 is provided on the top of the top cover 8. The top cover 8 is a flat cover that matches the upper diameter of the feeding hopper 7, and one side is hinged to the outer wall of the feeding hopper 7 via a stainless steel hinge 16. A bow-shaped handle 14 is fixedly installed in the center of the top of the top cover 8. The hinge design of the hinge 16 enables the top cover 8 to be opened and closed with one hand, making operation convenient and quick, and improving feeding efficiency. The handle 14 is easy for the operator to apply force, and can be used easily even when wearing gloves.

[0024] A bearing and a sealing ring are installed at the point where the stirring shaft 5 passes through the vertical arm of the L-shaped plate 1. A hard alloy layer is inlaid on the outer edge of the cutting teeth 6. A pair of deep groove ball bearings are installed in the through hole of the vertical arm of the L-shaped plate 1 to support the stirring shaft 5. High-temperature resistant nitrile rubber or fluororubber sealing rings are installed on the inner and outer sides of the bearings. The cutting edge or outer edge of the cutting teeth 6 is covered with a layer of tungsten carbide hard alloy through welding or inlaying. The bearings ensure the stability and precision of the stirring shaft 5 during high-speed rotation. The sealing rings form a dynamic seal, effectively preventing dust from entering the bearing chamber and causing wear, while also preventing grease contamination and extending service life. The hard alloy layer has high hardness and strong wear resistance, extending service life and reducing maintenance and replacement frequency.

[0025] A sealing strip 15 is provided at the contact edge between the top cover 8 and the feeding hopper 7. A ring groove is formed at the bottom edge of the top cover 8, and the sealing strip 15, made of high-temperature resistant silicone rubber, is embedded within the groove. When the top cover 8 is closed, the sealing strip 15 forms a tight compression contact with the upper edge of the feeding hopper 7. This effectively seals the feeding port, preventing the escape of trace amounts of metal dust generated during the smelting process.

[0026] The inner surface of the U-shaped slot 11 is provided with an anti-slip pad. The U-shaped slot 11 is embedded in the top vertical plate of the side wall of the smelting furnace, and the anti-slip pad is made of rubber. The inner surface of the U-shaped slot 11 at the bottom of the support base 10, that is, the two sides in contact with the vertical plate of the smelting furnace, is fully covered with the anti-slip pad by a high-strength adhesive. The anti-slip pad is preferably made of high-temperature resistant rubber or silicone, with a thickness between 3-10mm. The anti-slip pad effectively prevents the device from sliding or shifting on the furnace body, avoids hard contact between the metal support base 10 and the steel structure of the smelting furnace body, prevents mutual scratches, and plays a shock-absorbing and buffering role, compensating for the unevenness of the surface of the vertical plate of the smelting furnace, making the installation contact surface fit better and adaptability better.

[0027] The technologies, shapes, and structures not described in detail in this specification are prior art known to those skilled in the art.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
