Description

Technical Field

[0001] This utility model belongs to the field of molten iron ladle technology, and in particular relates to a structure for a molten iron ladle used in smelting and processing. Background Technology

[0002] In the smelting and processing industry, ladles of molten iron are widely used, primarily for holding and transporting high-temperature molten iron. Traditional ladles often employ a single-cylinder design, which has several drawbacks. First, due to the extremely high temperature of the molten iron, prolonged storage can cause the cylinder to expand due to heat, even deforming, affecting the safe transport of the molten iron. Furthermore, traditional ladles tend to accumulate slag and dirt inside over long-term use, making cleaning difficult and impacting their performance and lifespan.

[0003] A prior art patent document with authorization publication number CN211248311U discloses a molten iron casting ladle structure, including a vertical cylindrical outer cylinder of the molten iron ladle, and a vertical cylindrical inner lining of the molten iron ladle with its upper bottom face tilted forward and upward fixedly attached to the inner surface of the outer cylinder. This structure of the molten iron ladle is a single-cylinder design, which, with long-term use, is inconvenient for cleaning, maintenance, and replacement, affecting the overall service life of the molten iron ladle. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a molten iron ladle structure for smelting and processing, which effectively solves the problem that the existing molten iron ladle uses a single cylindrical design, which is convenient for cleaning, maintenance and replacement, and affects the overall service life of the molten iron ladle.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a molten iron ladle structure for smelting and processing.

[0006] The device includes an outer cylinder, the outer wall of which is rotatably equipped with a hoisting bracket. One side of the hoisting bracket is equipped with a power mechanism for driving the outer cylinder to rotate. The outer cylinder contains a detachable inner core cylinder for containing high-temperature molten iron. The inner core cylinder and the outer cylinder are positioned and fitted by a limiting structure. The inner core cylinder and the outer cylinder are positioned and connected by a connecting component.

[0007] A cavity for heat insulation is formed on the side wall of the outer cylinder.

[0008] Furthermore, the limiting structure includes a cross-shaped protrusion on the lower surface of the inner core cylinder and a cross-shaped groove on the upper surface of the outer cylinder, wherein the cross-shaped protrusion is correspondingly engaged in the cross-shaped groove.

[0009] Furthermore, the limiting structure includes a limiting block disposed on the lower surface of the bottom of the inner core cylinder and a limiting groove disposed on the upper surface of the bottom of the outer cylinder. The limiting blocks are a plurality of those distributed along the circumference, and the limiting grooves are vertically distributed in correspondence with the limiting blocks.

[0010] Furthermore, the connecting assembly includes a connecting screw with a positioning nut, a first connecting lug on the side wall of the outer cylinder, and a second connecting lug corresponding to the first connecting lug on the top end of the inner core cylinder extending upward beyond the outer cylinder. The connecting screw passes through the first and second connecting lugs in sequence and is locked and positioned by the positioning nut.

[0011] Furthermore, the width of the cavity is L1, and 2cm≤L1≤5cm.

[0012] Furthermore, a corrugated reinforcing wall is formed on the side wall of the cavity that is close to the inner core cylinder.

[0013] Furthermore, the top of the inner core cylinder is provided with a removable cover plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The inner core cylinder of this utility model is designed to be detachable, which facilitates cleaning, maintenance and replacement, and extends the service life of the molten iron ladle.

[0016] 2. In this utility model, the limiting structure facilitates positioning and installation, and also makes subsequent positioning and connection via connecting components easier. Furthermore, the cross-shaped protrusion in the limiting structure forms a reinforcing structure at the bottom of the inner core cylinder, enhancing its rigidity and deformation resistance. Under the pressure of high-temperature molten iron, the bottom is prone to significant stress; the cross-shaped protrusion can disperse this stress, preventing deformation or cracking. Moreover, during the pouring or dumping of molten iron, the bottom of the inner core cylinder may be subjected to impact forces. The cross-shaped protrusion enhances the bottom's impact resistance, preventing bottom breakage.

[0017] 3. The cavity primarily serves as insulation, reducing heat transfer from the inner core to the outer cylinder. Inside the cavity, the sidewall closest to the molten iron is a corrugated reinforced wall. Its corrugated shape significantly increases the strength of the outer cylinder's sidewalls, resisting the thermal and mechanical stresses generated by the molten iron. The corrugated structure possesses high bending and compressive strength, effectively preventing deformation of the cavity's inner sidewalls under high temperature and load. By enhancing structural strength and optimizing insulation performance, the service life of the outer cylinder is extended, reducing the frequency of maintenance and replacement.

[0026] 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.

[0027] like Figures 1-3 ,as well as Figure 5 and Figure 7 As shown, a molten iron ladle structure for smelting and processing.

[0028] The system includes an outer cylinder 1, with a rotatable lifting bracket 2 mounted on its outer wall. A power mechanism 3, which drives the outer cylinder 1 to rotate, is located on one side of the lifting bracket 2. Symmetrical support shafts are mounted on the side walls of the outer cylinder 1, and the side support of the lifting bracket 2 is rotatably mounted on these support shafts. The power mechanism 3 is a conventional structure. In this embodiment, referring to the accompanying drawings, the power mechanism includes a base, a motor mounted on the base, and a drive shaft rotatably mounted below the base. The drive shaft rotates via the motor, gears, and a transmission chain. The drive shaft includes a worm gear section, and a worm wheel, cooperating with the worm, is located on the side wall of the outer cylinder 1 near the drive shaft and extends into the machine housing. The worm gear drives the worm wheel to rotate, which in turn drives the support shaft to rotate. The rotation of the support shaft causes the outer cylinder 1 to rotate, thus achieving the rotation of the outer cylinder 1 for casting.

[0029] The outer cylinder 1 is equipped with a detachable inner core cylinder 4, which is used to contain high-temperature molten iron. The inner core cylinder 4 and the outer cylinder 1 are positioned and matched by a limiting structure.

[0030] The inner core cylinder 4 is designed to be detachable, which facilitates cleaning, maintenance and replacement, and extends the service life of the molten iron ladle.

[0031] In this embodiment, the limiting structure includes a cross-shaped protrusion 41 on the lower surface of the inner core cylinder 4 and a cross-shaped groove 11 on the upper surface of the bottom of the outer cylinder 1, with the cross-shaped protrusion 41 correspondingly locked in the cross-shaped groove 11.

[0032] When the inner core cylinder 4 is placed inside the outer cylinder 1, the cross-shaped protrusion 41 needs to be placed in the corresponding cross-shaped groove 11. The precise positioning between the inner core cylinder 4 and the outer cylinder 1 is achieved through the cooperation of the cross-shaped protrusion 41 and the cross-shaped groove 11. In addition, the cooperation between the cross-shaped protrusion 41 and the cross-shaped groove 11 prevents relative rotation between the inner core cylinder 4 and the outer cylinder 1, which facilitates the subsequent positioning and connection through connecting components.

[0033] Furthermore, the cross-shaped protrusion 41 forms a reinforcing structure at the bottom of the inner core cylinder 4, enhancing its rigidity and deformation resistance. Under the pressure of high-temperature molten iron, the bottom is prone to significant stress; the cross-shaped protrusion 41 can disperse this stress, preventing deformation or cracking. Moreover, during the pouring or dumping of molten iron, the bottom of the inner core cylinder 4 may be subjected to impact forces. The cross-shaped protrusion 41 enhances the bottom's impact resistance, preventing bottom breakage.

[0034] The inner core cylinder 4 and the outer cylinder 1 are positioned and connected by a connecting component.

[0035] In this embodiment, the connecting assembly includes a connecting screw 5, a positioning nut on the connecting screw 5, a first connecting lug 13 on the side wall of the outer cylinder 1, and the top end of the inner core cylinder 4 extends upward beyond the outer cylinder 1 and a second connecting lug 43 corresponding to the first connecting lug 13 is provided on the extended part. The connecting screw 5 passes through the first connecting lug 13 and the second connecting lug 43 in sequence and is locked and positioned by the positioning nut.

[0036] During installation, after the inner core cylinder 4 is placed into the outer cylinder 1, the inner core cylinder 4 and the outer cylinder 1 are fixedly connected together by the connecting screw 5.

[0037] A cavity 10 for heat insulation is formed on the side wall of the outer cylinder 1.

[0038] In this embodiment, the width of the cavity 10 is L1, and L1 is 3cm. The width L1 of the cavity 10 is 3cm. This width ensures the heat insulation effect without significantly affecting the structural strength of the outer cylinder 1.

[0039] The cavity 10 is mainly used for heat insulation to reduce the transfer of heat from the inner core cylinder 4 to the outer cylinder 1.

[0040] In this embodiment, a corrugated reinforcing wall 101 is formed on the side wall of the cavity 10 that is close to the inner core cylinder 4.

[0041] Inside the cavity 10, the sidewall closest to the molten iron is a corrugated reinforced wall 101. Its corrugated shape significantly increases the strength of the outer cylinder 1's sidewall, resisting the thermal and mechanical stresses generated by the molten iron. The corrugated structure has high bending and compressive strength, effectively preventing deformation of the inner sidewall of the cavity under high temperature and load. By enhancing structural strength and optimizing thermal insulation performance, the service life of the outer cylinder 1 is extended, reducing the frequency of maintenance and replacement.

[0042] In this embodiment, the top of the inner core cylinder 4 is provided with a detachable cover plate 6.

[0043] The edge of the cover plate 6 extends outward beyond the edge of the inner core cylinder 4. The lower surface of the extended edge is provided with a threaded post. The outer wall of the outer cylinder 1 is provided with a connecting ring. The threaded post passes through the connecting ring and is then tightened by a nut.

[0044] Example 2, as Figure 4 , Figure 6 As shown,

[0045] The difference between this embodiment and embodiment 1 is that, in this embodiment, the limiting structure includes a limiting block 42 disposed on the lower surface of the bottom of the inner core cylinder 4 and a limiting groove 12 disposed on the upper surface of the bottom of the outer cylinder 1. The limiting block 42 is a plurality of those distributed along the circumference, and the limiting groove 12 is vertically corresponding to the limiting block 42.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
