Description

Technical Field

[0001] This utility model relates to the field of slag jar technology, specifically to a slag jar with a lid positioning device. Background Technology

[0002] The slag trap is an important piece of equipment in the steelmaking process of the metallurgical industry, mainly used to hold the high-temperature molten slag generated during steelmaking. In the structural design of a vertical slag trap, the lid is located at the top of the trap, with a ring of locking teeth on the inner edge of the opening and a ring of mating teeth on the outer edge of the lid.

[0003] When the tank lid is closed, it is first tilted down by a hydraulic tilting arm and suspended above the slag tank by a lifting hydraulic cylinder and a lifting guide sleeve. Then, the lifting hydraulic cylinder drives the lid downwards, causing the mating teeth to engage with the grooves between adjacent locking teeth, achieving initial engagement between the outer edge of the lid and the inner edge of the tank opening. Continued downward pressure forces the mating teeth through the grooves. Once the lid is fully depressed, the locking cylinder rotates the lid, causing the mating teeth and locking teeth to align vertically, ultimately completing the sealing and closing operation. Opening the lid is achieved by performing the reverse operation.

[0004] Because the can lid needs to be rotated and locked after being pressed down, and the rotation of the can lid requires a certain degree of freedom, the lifting guide sleeve is not equipped with an anti-rotation guide function. Under these circumstances, during the tilting process of the hydraulic tilting arm, the can lid is prone to angular displacement, making it difficult for the mating teeth and grooves to be accurately aligned when the can lid falls. If forced down, it can easily cause damage to the equipment. Currently, existing technologies mostly rely on manual rotation of the can lid to achieve precise alignment of the teeth. However, this method is not only labor-intensive and prone to operational errors, but also poses significant safety risks in high-temperature and complex metallurgical work environments. Utility Model Content

[0005] To address the issue that when closing the lid of a slag-sealing tank, the lid is prone to angular displacement during the tilting process of the hydraulic tilting arm, making it difficult to accurately align the mating teeth and grooves when the lid falls. Existing technologies often rely on manual rotation of the lid to assist in achieving precise alignment of the teeth. However, this method is not only labor-intensive and prone to operational errors, but also poses significant safety risks in high-temperature and complex metallurgical work environments. This utility model provides a slag-sealing tank with a lid positioning device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A slag-sealing tank with a lid positioning device includes a tank body. A tilting arm is provided on the side of the tank body, and the bottom of the tilting arm is hinged to a rotating shaft. The top center of the lid is connected to the output end of a vertical lifting mechanism, which is connected to the top of the tilting arm. The top of the tank body has a circular opening. A plurality of locking teeth are evenly spaced along the inner edge of the opening, with locking grooves between adjacent locking teeth. A plurality of mating teeth are evenly spaced along the outer edge of the lid, with the number of mating teeth equal to the number of locking teeth. The mating teeth and locking grooves can engage in a concave-convex fit. When the concave and convex parts are engaged, there is a clearance L on the same side of the mating tooth block and the locking tooth groove in the circumferential direction. A positioning device is connected to one side of the tilting arm. The positioning device is located between the tank body and the tilting arm. The positioning device includes two baffles, both of which are parallel to the output direction of the vertical lifting mechanism. When the tank lid is closed, the bottom of both baffles is in contact with the top of the tank body. The opposite sides of the two baffles are located between the two sides in the circumferential direction of the same locking tooth groove. The distance between the side of each baffle facing the other baffle and the side in the same direction of the locking tooth groove is H, and the value of H is less than L.

[0008] With the above structure, when the can lid is closed, the bottoms of the two baffles are in contact with the top of the can, and the opposite sides of the two baffles are located on both sides of the same locking tooth groove. When the can lid is opened, the can lid rotates under the push of the locking cylinder, and the mating tooth block and the locking tooth block are misaligned. When each mating tooth block is aligned with the locking tooth groove, the vertical lifting mechanism drives the can lid to move upward. After the mating tooth block moves out of the locking tooth groove, it continues to move upward. Since the value of H is less than L, one of the mating tooth blocks can smoothly enter between the two baffles. The two baffles can restrict the movement of the mating tooth block in the circumferential direction, thereby restricting the rotation of the can lid. Since the positioning device is connected to the flipping arm, during the flipping arm flipping process, the two baffles can flip synchronously with the flipping arm and the can lid. Therefore, the can lid will be restricted by the two baffles until it is closed again. When the lid is closed again, the mating teeth on the lid can be aligned with the locking teeth under the restriction of the two baffles. When the lid is lowered, the mating teeth can fall into the locking teeth, avoiding manual adjustment, reducing labor intensity and safety risks, and reducing damage to the equipment caused by forced pressure.

[0009] As a preferred implementation of a slag tank with a lid positioning device, when the lid is closed, each baffle is arranged parallel to the side of the locking tooth groove in the same direction.

[0010] By adopting the above-mentioned structural method, the guiding effect of the baffle on the can lid is more uniform and stable during the descent of the can lid, which further improves the positioning accuracy of the can lid and ensures that the mating tooth block can fall into the tooth groove at the optimal angle and position, thereby improving the reliability of the can lid closing.

[0011] In a preferred embodiment of a slag tank with a lid positioning device, when the lid is closed, the distance H between the side of each baffle facing another baffle and the side of the locking tooth groove in the same direction is equal.

[0012] By adopting the above structural method, the difference in positioning distance between the two baffles is eliminated, further improving the accuracy of the alignment between the mating tooth block and the locking tooth groove, ensuring the stability of the can lid closing process, and improving the overall accuracy and efficiency of the equipment operation.

[0013] As a preferred implementation of a slag tank with a lid positioning device, a rounded chamfer is provided between the bottom surface of each baffle and the side of the baffle opposite to another baffle.

[0014] By adopting the above structural method, the rounded chamfer can effectively reduce the friction between the toothed block and the baffle when the can lid is raised.

[0015] As a preferred implementation of a slag tank with a lid positioning device, each baffle is provided with a reinforcing plate on the side away from the other baffle. The reinforcing plate is set perpendicular to the baffle and perpendicular to the output direction of the vertical lifting mechanism.

[0016] By adopting the above structural method, the structural strength and rigidity of the baffle are enhanced, ensuring the long-term stable operation of the positioning device and improving the reliability and safety of the equipment.

[0017] As a preferred implementation of a slag tank with a lid positioning device, the reinforcing plate and the baffle are welded together.

[0018] With the above-mentioned structural method, the reinforcing plate and the baffle are connected by welding to form a solid overall structure, ensuring that the reinforcing plate can effectively enhance the strength of the baffle and avoid failure of the reinforcing plate due to loose connection during equipment operation, thus ensuring the stability and reliability of the positioning device structure.

[0019] In a preferred embodiment of a slag tank with a lid positioning device, the positioning device is welded to the tilting arm.

[0020] By adopting the above-mentioned structural method, the stability of the positioning device during the flipping and lifting process is improved, preventing displacement or loosening of the positioning device, ensuring its positioning effect on the can lid, and enhancing the reliability of equipment operation.

[0021] In a preferred embodiment of a slag tank with a lid positioning device, the two baffles have equal thickness.

[0022] The above structural design ensures that both the baffle and the can lid are subjected to balanced forces.

[0023] As a preferred implementation of a slag tank with a lid positioning device, both baffles are provided with elastic blocks at their bottoms.

[0024] With the above-mentioned structure, when the baffle flips downward under the action of the flipping lever, and the bottom of the baffle contacts the top of the tank, the elastic block can play a buffering and shock-absorbing role, reducing the impact force between the baffle and the top of the tank when it flips down, while protecting the flipping lever and the tank cover, extending the service life of the equipment, and improving the safety of equipment operation.

[0025] As a preferred implementation of a slag tank with a lid positioning device, both baffles have heat dissipation holes.

[0026] With the above-mentioned structure, the slag tank will generate heat during operation. The heat dissipation holes on the baffle help dissipate heat, reduce heat transfer, and prevent the baffle or the tilting arm from deforming or being damaged due to high temperature, thereby improving the high temperature resistance and working stability of the equipment.

[0027] The beneficial effects of this utility model include:

[0028] The two baffles of the positioning device can restrict the movement of a mating tooth block on the can lid in the circumferential direction when the can lid is raised and lowered, thereby restricting the rotation of the can lid and ensuring that the mating tooth block on the can lid is correctly aligned with the locking tooth groove.

[0038] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Reference Figure 1-6 This embodiment proposes a slag-sealing tank with a lid positioning device, including a tank body 1. A tilting arm 2 is provided on the side of the tank body 1, and the bottom of the tilting arm 2 is hinged to a rotating shaft 3. The top center of the lid 4 is connected to the output end of a vertical lifting mechanism 5, which is connected to the top of the tilting arm 2. The top of the tank body 1 has a circular opening. A plurality of locking teeth 6 are evenly spaced along the inner edge of the opening, and a locking groove 7 is formed between adjacent locking teeth 6. A plurality of mating teeth 8 are evenly spaced along the outer edge of the lid 4. The number of mating teeth 8 is equal to the number of locking teeth 6, and the mating teeth 8 and the locking groove 7 can engage in a concave-convex fit. When the mating teeth 8 and the locking groove 7 engage in a concave-convex fit, there is a mating gap L on the same side in the circumferential direction between the mating teeth 8 and the locking groove 7. The tilting arm 2 can be driven by hydraulic drive, and its drive structure is a prior art well known to those skilled in the art, and will not be described further in this embodiment. The vertical lifting mechanism 5 can be a common mechanism used in the market for lifting the lid 4 of a slag tank.

[0040] A positioning device is welded to one side of the tilting arm 2. The positioning device is located between the tank body 1 and the tilting arm 2. The positioning device includes two baffles 9, both of which are parallel to the output direction of the vertical lifting mechanism 5. The two baffles 9 have the same thickness and both have heat dissipation holes 10. Both baffles 9 have elastic blocks 11 at their bottoms. A reinforcing plate 12 is welded to the side of each baffle 9 away from the other baffle 9. The reinforcing plate 12 is perpendicular to the baffle 9 and perpendicular to the output direction of the vertical lifting mechanism 5. A rounded chamfer 13 is provided between the bottom surface of each baffle 9 and the side of the baffle 9 opposite to the other baffle 9.

[0041] With the can lid 4 closed, the bottoms of both baffles 9 are in contact with the top of the can body 1. The opposite sides of the two baffles 9 are located between the two sides of the same locking groove 7 in the circumferential direction. The distance H between the side of each baffle 9 facing the other baffle 9 and the side of the locking groove 7 in the same direction is less than L. Each baffle 9 is arranged parallel to the side of the locking groove 7 in the same direction. The distance H between the side of each baffle 9 facing the other baffle 9 and the side of the locking groove 7 in the same direction is equal, that is, the included angle θ between the two baffles 9 is equal to the included angle between the two sides of the locking groove 7 in the circumferential direction.

[0042] Work process:

[0043] When the can lid 4 needs to be opened, the locking cylinder pushes the can lid 4 to rotate, causing the mating tooth block 8 to be misaligned with the locking tooth block 6. At this time, each mating tooth block 8 is aligned with the locking tooth groove 7. Subsequently, the vertical lifting mechanism 5 moves the can lid 4 upward, and the mating tooth block 8 moves out of the locking tooth groove 7 and continues to rise. Since the value of H is less than L, one of the mating tooth blocks 8 can smoothly enter between the two baffles 9 above. At this time, the two baffles 9 can restrict the movement of the mating tooth block 8 in the circumferential direction, thereby restricting the rotation of the can lid 4.

[0044] Because the positioning device is connected to the flipping arm 2, when the flipping arm 2 performs the flipping action under the hinge action of the rotating shaft 3, the two baffles 9 will flip synchronously with the flipping arm 2 and the can lid 4. Throughout the flipping process, the can lid 4 is always restricted from rotating by the two baffles 9, ensuring that the can lid 4 will not deviate in angle during the flipping process.

[0045] When the can lid 4 needs to be closed, the tilting arm 2 tilts the can lid 4 to a suitable position above the can body 1, and then the vertical lifting mechanism 5 begins to lower the can lid 4. During the descent, the rotation of the can lid 4 is restricted by two baffles 9, and the opposite sides of the two baffles 9 are located between the two sides of the same locking groove 7 in the circumferential direction. Therefore, the mating tooth block 8 on the can lid 4 can be accurately aligned with the locking groove 7 on the can opening of the can body 1 under the constraint and guidance of the baffles 9. As the can lid 4 continues to descend, the mating tooth block 8 falls smoothly into the locking groove 7, completing the initial engagement. Then, the lifting hydraulic cylinder continues to press down the can lid 4, causing the mating tooth block 8 to pass through the groove. After being pressed into place, the locking cylinder pushes the can lid 4 to rotate and lock, causing the mating tooth block 8 to misalign with the locking groove 7. Finally, the mating tooth block 8 can overlap with the locking tooth block 6, achieving reliable closure of the can lid 4.

[0046] The locking cylinder in the above working process is a structure in the prior art. Those skilled in the art are familiar with its structure, installation method and use principle, and it will not be described in detail in this embodiment.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
