Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically a system for efficiently recovering waste heat from materials. Background Technology

[0002] Chinese patent document CN212585447U discloses a high-temperature solid material waste heat recovery system with a vertical kiln structure, including a vertical kiln, a three-stage heat exchanger, a steam generator set, and a steam generator. A cooler is connected to the outlet of the steam generator set. The vertical kiln includes several vertically placed baffles, each with a baffle interlayer. Both ends of the baffle interlayer are connected to the three-stage heat exchanger via pipes. Liquid metal is contained within the baffle interlayer. The three-stage heat exchanger is divided into a superheating section, a steam section, and a preheating section. The liquid metal flows sequentially through these sections. The steam generator's steam outlet is connected to the steam generator set via a pipe through the superheating section, and the steam generator set's outlet is connected to the cooler. A pipe connected to the cooler passes through the preheating section and leads to the steam generator. This invention utilizes the high-temperature flow of liquid metal for heat exchange, resulting in high waste heat recovery efficiency and a high degree of automation. It is suitable for the metallurgical, calcium carbide, cement, and chemical industries.

[0003] However, in the above-mentioned solutions and existing technologies, the steel balls used in the ball mill are manufactured through a hot rolling process. During the manufacturing process, the rolled red-hot steel balls need to be quenched and tempered in an online heat treatment device. When the red-hot steel balls enter the quenching tank, the residual heat of the material reacts with water to generate a large amount of high-temperature steam. The generated high-temperature steam can be recovered and reused through a steam recovery system, thereby achieving efficient recovery and reuse of the residual heat of the material. A steam recovery pipeline is set above the quenching tank to collect the high-temperature steam, and a dust filter plate is set on the baffle at the steam recovery pipe opening to filter out the dust and impurities mixed in with the high-temperature steam. The dust filter plate needs to be disassembled and cleaned regularly. During operation, personnel need to extend their heads and hands to the bottom of the baffle and use auxiliary tools to unscrew the screws used to fix the dust filter plate. The operation is inconvenient, and there is a risk of personnel being hit by the dust filter plate when their heads are extended to the bottom of the baffle. Improvement and optimization are needed.

[0004] Therefore, this utility model proposes a system for efficiently recovering waste heat from materials to solve the above problems. Utility Model Content

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figures 1-5 This utility model provides a technical solution: a system for efficiently recovering waste heat from materials, comprising: a steam recovery pipe 2, a baffle 1 fixedly sleeved at the bottom end of the steam recovery pipe, a groove 3 at the bottom end of the baffle 1, a fixed frame 4 connected to the top end of the baffle 1, and mounting holes 5 symmetrically opened on both sides of the fixed frame 4; a dust filter assembly is provided on the baffle 1.

[0017] Mounting holes 5 are provided on the fixed frame 4 for fixing the frame 4 and the baffle 1 to be installed above the quenching tank. After the red-hot steel billet material enters the quenching tank, the residual heat of the material reacts with water to generate a large amount of high-temperature steam, which is extracted and recycled along the steam recovery pipe 2 to achieve efficient recovery and utilization of the material's residual heat.

[0018] The fixed frame 4 has symmetrical movable grooves 6 on both sides of the wall. The movable grooves 6 pass through the baffle 1. The T-shaped plate 7 in the dust filter assembly is movably inserted into the movable groove 6. Damping shock absorbers 8 are equidistantly connected on the end wall of the fixed frame 4. The bottom ends of the protrusions on both sides of the T-shaped plate 7 are engaged with the ends of the damping shock absorbers 8.

[0019] The T-shaped plate 7 is movably inserted into the movable groove 6. The bottom end of the T-shaped plate 7 extends to the bottom side of the baffle 1. The bottom ends of the protrusions on both sides of the T-shaped plate 7 are engaged with the ends of the damping shock absorber 8, so that the T-shaped plate 7 contacts the damping shock absorber 8 when it descends, and the damping shock absorber 8 plays a buffering and shock-absorbing role.

[0020] The bottom side wall of the T-shaped plate 7 is connected to an L-shaped hanging plate 9. The dust filter plate 10 is inserted into the groove 3. The side wall of the dust filter plate 10 is symmetrically provided with positioning grooves 11. The positioning grooves 11 are inserted into the protrusion on one side of the L-shaped hanging plate 9. The bottom wall of the dust filter plate 10 is engaged with the inner side wall of the L-shaped hanging plate 9.

[0021] The protrusion on one side of the L-shaped hanging plate 9 is inserted into the positioning groove 11 on the dust filter plate 10 for positioning and installation of the dust filter plate 10. The bottom wall of the dust filter plate 10 is engaged with the inner wall of the L-shaped hanging plate 9, so that the dust filter plate 10 is hung on the L-shaped hanging plate 9.

[0022] The dust filter plate 10 has symmetrical slots 12 on both sides, and the bottom side wall of the T-shaped plate 7 has an L-shaped groove 13. A limit post 14 is connected to the side wall of the L-shaped groove 13. An L-shaped insert plate 15 is movably inserted into the L-shaped groove 13, and the end of the L-shaped insert plate 15 is inserted into the slot 12.

[0023] When the L-shaped insert plate 15, which is movably inserted into the L-shaped groove 13, moves, the end of the L-shaped insert plate 15 is inserted into the slot 12 to fix the position of the dust filter plate 10, so that the dust filter plate 10 can move up and down with the T-shaped plate 7.

[0024] The L-shaped insert plate 15 has a sliding groove 16 on its side wall, and the limiting post 14 is movably engaged in the sliding groove 16. A first magnetic block 17 is fixedly embedded in the side wall of the L-shaped insert plate 15, and a second magnetic block 18 is fixedly embedded in the side wall of the L-shaped groove 13. The first magnetic block 17 and the second magnetic block 18 attract each other.

[0025] The limiting post 14 is movably engaged in the slide groove 16 to limit the range of movement of the L-shaped insert 15 and prevent the L-shaped insert 15 from detaching. The first magnetic block 17 and the second magnetic block 18 attract each other to attract the L-shaped insert 15 into the L-shaped groove 13, ensuring that the L-shaped insert 15 is stably inserted into the slot 12.

[0026] The T-shaped plate 7 has a limiting hole 19 on its side wall, and the convex plate 20 is symmetrically connected to the side wall of the cover 1. The convex plate 20 is threadedly connected to the side wall of the cover 1, and a hand-tightening bolt 21 is provided. The end of the hand-tightening bolt 21 is connected to a limiting block 22, and the limiting block 22 is inserted into the limiting hole 19.

[0027] Turning the hand-tightening bolt 21 controls the movement of the limiting block 22. The limiting block 22 is inserted into the limiting hole 19 on the side wall of the T-shaped plate 7 to fix the position of the T-shaped plate 7.

[0028] Working principle: Insert the protrusion on one side of the L-shaped hanging plate 9 into the positioning groove 11 on the dust filter plate 10 until the bottom wall of the dust filter plate 10 is engaged with the inner wall of the L-shaped hanging plate 9, thus positioning and hanging the dust filter plate 10 on the L-shaped hanging plate 9. Then, move the L-shaped insert 15 along the L-shaped groove 13 until the first magnetic block 17 and the second magnetic block 18 attract and hold the L-shaped insert 15. The end of the L-shaped insert 15 is then inserted into the slot 12 to fix the position of the dust filter plate 10. Then, move the T-shaped plate 7 upward until the dust filter plate 10 is inserted into the groove 3. At this time, the side wall of the movable groove 6 limits the side wall of the L-shaped insert 15 to further prevent the L-shaped insert 15 from separating from the slot 12. Turning the hand-tightening bolt 21 can control the movement of the limiting block 22, so that the limiting block 22 is inserted into the limiting hole 19 on the side wall of the T-shaped plate 7 to fix the position of the T-shaped plate 7. After the installation of the dust filter plate 10 is completed, the red-hot steel billet material enters the quenching tank. The residual heat of the material reacts with water to generate a large amount of high-temperature steam, which is extracted and recycled along the steam recovery pipe 2, realizing the efficient recovery and utilization of the residual heat of the material. The dust filter plate filters out the dust and impurities mixed in with the high-temperature steam. When disassembling and cleaning the dust filter plate, turn the hand-tightening bolt 21 to control the separation of the limiting block 22 from the limiting hole 19. Under its own gravity, the T-shaped plate 7 and the dust filter plate 10 slide down until the bottom of the protrusions on both sides of the T-shaped plate 7 are engaged with the end of the damping shock absorber 8. The damping shock absorber 8 plays a buffering and shock-absorbing role. At this time, the dust filter plate 10 moves to the position below the baffle 1. The operator can remove the dust filter plate 10 from the side without the need for the operator's head and hands to reach under the baffle. The operation is simple and does not require the use of auxiliary tools, making it convenient to disassemble and assemble the dust filter plate.
