Description

Technical Field

[0001] This utility model relates to the field of dry quenching technology, specifically a preheating device for dry quenching treatment. Background Technology

[0002] Dry quenching, as opposed to wet quenching, refers to a quenching method that uses inert gas to cool red-hot coke. Its function is to heat the cooled coke to a suitable temperature before further cooling or other operations. Dry quenching technology reduces energy consumption while avoiding water vapor pollution and resource waste inherent in traditional wet quenching processes.

[0003] The existing technology has the following defects or problems: The existing technology disclosed in CN217838807U discloses a preheating device for dry quenching coke treatment, including: a preheating shell, a heat storage body rotatably installed in the inner cavity of the preheating shell, a rotating shaft interference fits the central hole of the heat storage body, the bottom end of the rotating shaft is rotatably installed in the inner cavity mounting groove of the preheating shell, the top end of the rotating shaft extends out of the surface of the preheating shell and is equipped with a motor; an exhaust gas inlet is installed on the right side of the top end of the preheating shell, an exhaust gas outlet is installed on the right side of the bottom end of the preheating shell, and an air inlet is installed on the left side of the top end of the preheating shell.

[0004] During use, the above-mentioned equipment allows the cleaning brush to fall onto the surface of the heat storage body by rotating the knob, and water is injected through the water pipe.

The first motor inside the electric groove is activated, driving the bidirectional lead screw to rotate inside the installation block. The bidirectional lead screw then drives two movable blocks to move in opposite directions. The movement of the movable blocks causes the rotating block to rotate, thereby pushing the support block. This causes the support block to lower the movable plate, which in turn brings the cleaning head to the upper surface of the heat storage body. The second motor is then activated, driving the cleaning head to rotate. This allows for large-area cleaning of the heat storage body's surface, saving labor and time.

[0029] Example 1

[0030] like Figures 1-6 As shown, this utility model provides a technical solution: a preheating device for dry quenching coke treatment, including a device body 1, an installation block 2 is inserted inside the device body 1, an electric groove 3 is opened inside the installation block 2, a first motor 4 is fixedly connected inside the electric groove 3, a bidirectional lead screw 5 is fixedly connected to the output end of the first motor 4, two movable blocks 6 are threadedly connected to the outer surface of the bidirectional lead screw 5, a rotating block 7 is rotatably connected to the lower surface of the two movable blocks 6, a movable plate 8 is slidably connected inside the installation block 2, two support blocks 9 are fixedly connected to the upper surface of the movable plate 8, the interior of the two support blocks 9 is rotatably connected to the other end of the rotating block 7, a second motor 10 is fixedly connected to the upper surface of the movable plate 8, a cleaning head 11 is fixedly connected to the output end of the second motor 10 through the movable plate 8, a limiting rod 30 is fixedly connected inside the installation block 2, and the interior of the limiting rod 30 is slidably connected to the interior of the movable block 6;

[0031] A motor 21 is fixedly connected to the upper surface of the device body 1. A connecting shaft 22 is fixedly connected to the output end of the motor 21. A heat storage body 23 is fixedly connected to the bottom end of the connecting shaft 22. The upper surface of the heat storage body 23 is movably connected to the cleaning head 11. An air intake pipe 24 is fixedly connected to the inside of the device body 1. An exhaust gas intake pipe 25 is fixedly connected to the inside of the device body 1. A controller 26 is fixedly connected to the outer surface of the device body 1. A water inlet pipe 27 is fixedly connected to the inside of the device body 1. Multiple support rods 28 are fixedly connected to the lower surface of the device body 1. A base plate 29 is fixedly connected to the bottom of the multiple support rods 28.

[0032] In this embodiment, the first motor 4 inside the power-on slot 3 is started, and the first motor 4 drives the bidirectional lead screw 5 to rotate inside the mounting block 2. The bidirectional lead screw 5 drives the two movable blocks 6 to move in opposite directions. The movement of the movable blocks 6 will drive the rotating block 7 to rotate, thereby pushing the support block 9, causing the support block 9 to drive the movable plate 8 to descend. The movable plate 8 brings the cleaning head 11 to the upper surface of the heat storage body 23. The second motor 10 is started, and the second motor 10 drives the cleaning head 11 to rotate, which can clean the surface of the heat storage body 23 over a wide area. The limiting rod 30 prevents the movable block 6 from shaking when it moves.

[0033] The device body 1 is fixed with a motor 21, an air intake pipe 24, an exhaust gas intake pipe 25, a controller 26, and a water inlet pipe 27. The exhaust gas from the boiler is discharged through the exhaust gas intake pipe 25 to heat the heat storage body 23, and the air is discharged through the air intake pipe 24 to preheat the air. The controller 26 controls the entire device, and the water inlet pipe 27 brings in water to spray on the outer surface of the heat storage body 23 for easy cleaning. The support rod 28 and the base plate 29 stabilize the whole.

[0034] Example 2

[0035] like Figures 1-6 As shown, two side slots 12 are opened on the other side of the device body 1. A damper 13 is fixedly connected inside the two side slots 12. A slider 14 is fixedly connected to the output end of the damper 13. A first recess 15 is fixedly connected to the outer surface of the slider 14. A rotating rod 16 is rotatably connected inside the first recess 15. A first spring 17 is fixedly connected inside the side slots 12. A locking block 18 is fixedly connected to the other end of the first spring 17. A second recess 19 is fixedly connected to the outer surface of the locking block 18. The interior of the second recess 19 is rotatably connected to the other end of the rotating rod 16. Slots 20 are opened on both sides of the interior of the mounting block 2. The interior of the slots 20 is engaged with the other end of the locking block 18. A second spring 31 is fixedly connected inside the side slots 12. The other end of the second spring 31 is fixedly connected to the bottom end of the slider 14.

[0036] In this embodiment, the slider 14 is manually pulled, and the direction of the slider 14 is stabilized by the damper 13. The slider 14 drives the first concave block 15 to move. When the first concave block 15 moves, it drives the rotating rod 16 to rotate. The rotating rod 16 pushes the second concave block 19, which drives the locking block 18 to move out of the slot 20. The mounting block 2, including its internal structure, can then be removed from the inside of the device body 1. The locking block 18 is fixed by the first spring 17, which also has a buffering effect. The second spring 31 assists the damper 13 in the operation of the slider 14.

[0037] The working principle of this embodiment is as follows: First, the first motor 4 inside the power-on slot 3 is started. The first motor 4 drives the bidirectional lead screw 5 to rotate inside the mounting block 2. The bidirectional lead screw 5 drives the two movable blocks 6 to move in opposite directions. The movement of the movable blocks 6 drives the rotating block 7 to rotate, thereby pushing the support block 9. The support block 9 drives the movable plate 8 to descend. The movable plate 8 brings the cleaning head 11 to the upper surface of the heat storage body 23. The second motor 10 is started. The second motor 10 drives the cleaning head 11 to rotate, which can clean the surface of the heat storage body 23 over a large area, saving manual labor and time. Second, the slider 14 is pulled manually. The direction of the slider 14 is stabilized by the damper 13. The slider 14 drives the first concave block 15 to move. When the first concave block 15 moves, it drives the rotating rod 16 to rotate. The rotating rod 16 pushes the second concave block 19, which drives the locking block 18 to move out of the slot 20. Thus, the mounting block 2, including its internal structure, can be mounted together. The device is easily removed from its internal structure for maintenance and replacement, facilitating its use. The device body 1 houses the motor 21, air intake pipe 24, exhaust gas intake pipe 25, controller 26, and water inlet pipe 27. The first spring 17 secures the locking block 18 while also providing a buffer. The motor 21 drives the connecting shaft 22 to rotate, which in turn rotates the heat storage body 23 inside the device body 1. Exhaust gas from the boiler is introduced through the exhaust gas intake pipe 25 to heat the heat storage body 23, while air is introduced through the air intake pipe 24 for preheating. The controller 26 controls the entire device, and the water inlet pipe 27 sprays water onto the outer surface of the heat storage body 23 for easy cleaning. The support rod 28 and base plate 29 stabilize the entire structure, and the limit rod 30 prevents the movable block 6 from shaking during movement. The second spring 31 assists the damper 13 in controlling the movement of the slider 14.

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 present utility model.
