Description

Technical Field

[0001] The utility model relates to the field of coke dry quenching, in particular to a rotary coke pot parking auxiliary mechanism. Background Art

[0002] Coke dry quenching, namely the abbreviation of dry coke quenching, is relative to wet coke quenching. It is a coke quenching method that uses inert gas to cool down the red-hot coke. During the coke dry quenching process, the red-hot coke (with a temperature of about 1000 °C) is charged from the top of the coke dry quenching furnace. The low-temperature inert gas is blown into the red-hot coke layer in the cooling section of the coke dry quenching furnace by a circulation fan, absorbs the sensible heat of the red-hot coke, and cools the coke to below 250 °C before discharging it from the bottom of the coke dry quenching furnace. The coke dry quenching technology can recover and utilize the sensible heat of the red-hot coke, generate steam for power generation or heating, and significantly improve the energy utilization rate.

[0003] After the red-hot coke is discharged from the coking chamber of the coke oven, it is transported by a rotary coke pot car and sent to the top of the coke dry quenching furnace. After the red-hot coke is loaded into the rotary coke pot car, it is necessary to rotate the coke pot to improve the loading coefficient and particle distribution of the coke. After rotation, it is necessary to stop the rotation of the coke pot. For this purpose, a rotary coke pot parking auxiliary mechanism is required.

[0004] At present, in the domestic coking industry, the deceleration and stop of the rotary coke pot of the coke quenching car adopt magnetic switches to detect signals and send them to the PLC system, and the rotation of the rotary coke pot is controlled by a program. There are 3 magnetic switches in total. One is used to trigger the deceleration signal, and the other 2 are used to trigger the stop signal. By adjusting the position of the deceleration magnetic switch, the time from deceleration to shutdown of the rotary coke pot can be adjusted. Once the deceleration position magnetic switch fails, it will cause the coke pot to rotate continuously at a high speed. If it cannot be forced to stop rotating, it will cause damage to mechanical equipment such as the rotary speed reducer, and the risk is relatively high. For this reason, a rotary coke pot parking auxiliary mechanism is proposed to solve the above problems. Content of the Utility Model

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 - Figure 2 , an embodiment provided by the present invention: A parking auxiliary mechanism for a rotating coke pot includes a bearing base 1 for bearing equipment. A rotating chassis 2 is arranged on the top of the bearing base 1. A rotating coke pot 3 is detachably connected to the top of the rotating chassis 2. The rotating chassis 2 can reduce the friction when the rotating coke pot 3 rotates. A support frame 4 is fixedly connected to the top of the bearing base 1. There are two groups of support frames 4, which are symmetrically arranged on the top surface of the bearing base 1 from left to right. A sliding groove 5 is opened inside the support frame 4. A slide block 6 is slidably connected inside the sliding groove 5. The sliding groove 5 restricts the slide block 6 to slide only up and down along the inner wall of the sliding groove 5. A support plate 7 for fixed support is fixedly connected to the inner side of the slide block 6. A lifting assembly is fixedly connected to the bottom of the support plate 7. The lifting assembly is used to lift the support plate 7. A parking auxiliary ring 8 is fixedly connected to the top of the support plate 7. The parking auxiliary ring 8 is located on the outer periphery of the rotating coke pot 3 and is provided with a groove inside. A resistance wheel 9 is rotatably connected inside the parking auxiliary ring 8. There are several groups of resistance wheels 9, which are evenly distributed in a ring in the groove of the parking auxiliary ring 8. The inner side of the resistance wheel 9 is in contact with the outer side of the rotating coke pot 3. The rapidly rotating rotating coke pot 3 can drive the resistance wheel 9 to rotate.

[0033] Referring to Figure 2 - Figure 3, a speed reduction component is fixedly connected to the top of the resistance wheel 9. The speed reduction component is used to change the output rotation speed. The speed reduction component includes a worm 10. The bottom of the worm 10 is fixedly connected to the top of the resistance wheel 9. The rotation of the resistance wheel 9 can drive the rotation of the worm 10. A worm gear 11 is meshed with the outer periphery of the worm 10. The rotation of the worm 10 can drive the rotation of the worm gear 11. At the same time, the rotation ratio is relatively large, so that the rotation speed of the worm gear 11 is slower. A rotation bracket 12 for fixing and supporting is rotatably connected to the back of the worm gear 11. The bottom end of the rotation bracket 12 is fixedly connected to the top of the parking assist ring 8. A rotation disc 13 is fixedly connected to the outside of the speed reduction component. The outside of the worm gear 11 is fixedly connected to the inside of the rotation disc 13. The rotation of the worm gear 11 can drive the rotation of the rotation disc 13. A rotation column 14 is fixedly connected to the outside of the rotation disc 13. The rotation column 14 is located at a non-central position of the rotation disc 13. The rotation of the rotation disc 13 can drive the rotation column 14 to rotate around the center of the rotation disc 13. A connecting rod 15 is hinged to the outer periphery of the rotation column 14. A fixing bracket 17 for fixing and supporting is fixedly connected to the top of the parking assist ring 8. The number of the fixing brackets 17 is equal to the number of the resistance wheels 9 and the positions are opposite. A hydraulic damper 16 for providing a deceleration resistance to the rotary coke pot 3 is fixedly connected to the inside of the fixing bracket 17. The top end of the connecting rod 15 is hinged to the bottom piston rod of the hydraulic damper 16. The rotation of the rotation column 14 will drive the bottom piston rod of the hydraulic damper 16 to slide up and down through the connecting rod 15. At this time, the hydraulic damper 16 will provide resistance, thereby reducing the rotation speed of the rotary coke pot 3 until it stops.

[0034] Refer to Figure 1 , Figure 3 and Figure 4, the lifting assembly includes a scissor lift 18. The top end of the scissor lift 18 is fixedly connected to the bottom of the support plate 7. When the scissor lift 18 is activated, it will drive the support plate 7 to move up and down. The bottom of the scissor lift 18 is fixedly connected to the top of the bearing base 1. A stabilizing rod 19 is fixedly connected inside the scissor lift 18. The stabilizing rod 19 can keep the two scissor arms on both sides of the scissor lift 18 synchronized, making the equipment more stable. There are two sets of stabilizing rods 19, symmetrically arranged front and back on the front and back of the scissor lift 18. A rotating ring 20 is rotatably connected to the outer periphery of the stabilizing rod 19. A sliding rod 21 is fixedly connected to the inner side of the rotating ring 20. A sliding sleeve 22 is slidably connected to the outer periphery of the sliding rod 21. The sliding sleeve 22 connects the front and back two sets of sliding rods 21. The sliding sleeve 22 restricts the front and back two sets of sliding rods 21 to only slide back and forth along the inner wall of the sliding sleeve 22. Buffer grooves 23 are provided at both ends of the sliding sleeve 22. The inner wall of the buffer groove 23 near the outside is elastically connected to a sliding round block 25 through a buffer spring 24. When the sliding round block 25 is not stressed, the buffer spring 24 will push the sliding round block 25 inward. One end of the buffer spring 24 is fixedly connected to the inner wall of the buffer groove 23 near the outside, and the other end of the buffer spring 24 is fixedly connected to the outside of the sliding round block 25. The outer periphery of the sliding round block 25 is slidably connected inside the buffer groove 23. The buffer groove 23 restricts the sliding round block 25 to only slide back and forth along the inner wall of the buffer groove 23.

[0035] Working principle: When it is necessary to urgently stop the rotation of the rotary coke pot 3, activate the lifting assembly, raise the support plate 7. The support plate 7 drives the parking auxiliary ring 8 to rise, and the parking auxiliary ring 8 drives the resistance wheel 9 to rise. When it rises to contact the outer wall of the rotary coke pot 3, the rotary coke pot 3 will drive the resistance wheel 9 to rotate. The resistance wheel 9 drives the worm 10 to rotate, and the worm 10 drives the worm gear 11 to rotate. At the same time, the rotation speed of the worm gear 11 is relatively slow. The worm gear 11 drives the rotating disk 13 to rotate, and the rotating disk 13 drives the rotating column 14 to rotate around the center of the rotating disk 13. The rotating column 14 drives the piston rod of the hydraulic damper 16 to slide up and down through the connecting rod 15, generating resistance. Thus, the resistance wheel 9 generates a resistance on the rotary coke pot 3 in the opposite direction to the rotation direction, making the rotary coke pot 3 gradually stop rotating and complete the parking. When the scissor lift 18 suddenly loses gravity, under the action of the top gravity, the top of the scissor lift 18 descends. At this time, the scissor arms of the scissor lift 18 open, driving the two side rotating rings 20 to move away from each other. The rotating ring 20 drives the sliding rod 21 to move outward along the sliding sleeve 22. The sliding rod 21 drives the sliding round block 25 to move outward, squeezing the buffer spring 24. At this time, the buffer spring 24 generates a reaction force, reducing the falling speed of the scissor lift 18, thereby reducing the damage caused during the fall.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
