Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste treatment, and in particular to a coke removal device for a municipal solid waste incinerator. Background Technology
[0002] China generates a large amount of municipal solid waste annually, with over 80% treated through high-temperature incineration. Waste incineration is currently the most advanced and effective treatment method in China, effectively achieving waste reduction, harmlessness, and resource recovery. However, during the high-temperature combustion process in the incinerator, coking easily occurs in the front and rear arches of the furnace. After approximately 4-6 months of operation, the coking becomes severe, blocking flue gas flow and significantly affecting normal combustion, necessitating shutdown and decoking. Currently, the main method for decoking involves erecting scaffolding or suspended baskets inside the furnace and manually operating at height using electric and pneumatic drills. This method is labor-intensive, inefficient, time-consuming, and the furnace environment is harsh, dusty, and poses significant safety hazards for workers at height. Utility Model Content

This is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0021] In the description of this utility model, if there is a description of quantity, "several" means one or more, "more than" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.
[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0023] like Figures 1 to 4 As shown, this utility model discloses a coke removal device for a municipal solid waste incinerator, including a translation and fixing mechanism, a lifting mechanism, and a coke removal mechanism. The translation and fixing mechanism includes a fixed steel wire rope 11, a lifting beam 12 installed on the fixed steel wire rope 11, and a traction assembly for driving the lifting beam 12 to translate. The lifting mechanism includes a lifting steel wire rope 21 located at the lower end of the lifting beam 12 and a lifting winch 22 for driving the lifting steel wire rope 21 to rise and fall. The coke removal mechanism includes a movable fixed mechanism connected to the lower end of the lifting steel wire rope 21. The system includes a support bracket 31, a telescopic mechanical arm 32 mounted on the lower end of the movable fixed support bracket 31, and a serrated rake 33 located on the lower end of the telescopic mechanical arm 32. The telescopic mechanical arm 32 is fixed to the movable fixed support bracket 31 by a translation slider 35. The movable fixed support bracket 31 is also equipped with a translation winch 34 for driving the translation slider 35 to translate. A hydraulic telescopic support column 36 is provided at each end of the movable fixed support bracket 31. There are two lifting wire ropes 21, and each rope has at least two branch lifting points at its lower end.
[0024] In use, first fix both ends of the fixing wire rope 11 to the two sides of the upper end of the furnace, located on the walkway platform, to facilitate installation. The two ends of the fixing wire rope 11 can be fixed to the walkway platform through quick-connect couplings for easy disassembly and assembly. Then, the traction assembly drives the lifting beam 12 to move left and right, thereby driving the lower moving fixed bracket 31 to move left and right to the designated position. Then, the lifting winch 22 and the lifting wire rope 21 drive the moving fixed bracket 31 to descend to the designated position. Then, control the hydraulic telescopic columns at both ends to extend and press against the inner wall of the furnace in the front and rear directions to complete the support and fixation. Finally, the telescopic mechanical arm 32 drives the sawtooth rake 33 to descend and crush and remove the coke block 4 at the designated position to achieve the effect of rapid coke removal.
[0025] The serrated rake 33 is made of a high-strength alloy material that is wear-resistant and corrosion-resistant, and the movable fixed bracket 31 is made of a high-strength alloy material that is lightweight, wear-resistant and corrosion-resistant. Its hydraulic telescopic support column 36 is driven by a hydraulic cylinder.
[0026] The lifting wire rope 21 consists of two ropes with at least two forked lifting points at the lower end, which enables the movable fixed support 31 to maintain stability and balance during movement.
[0027] In this invention, the traction assembly includes traction rope fixing brackets 16 at both ends of the fixed steel wire rope 11, a translational traction rope 13 passing through the two traction rope fixing brackets 16, a traction counterweight 15 at one end of the traction rope, and a traction winch 14 connected to the other end of the traction rope. The lifting beam 12 is fixedly connected to the middle of the traction rope. The traction winch 14 works in conjunction with the traction counterweight 15 to move the translational traction rope 13 left and right, thereby driving the lifting beam 12 to move left and right.
[0028] In this invention, the lifting beam 12 is mounted on the fixed steel wire rope 11 via pulleys to ensure smooth and stable translation.
[0029] In this invention, the fixing wire rope 11 consists of two parallel wire ropes, which further ensures the smooth movement of the lifting beam 12.
[0030] In this invention, the serrated rake 33 includes two parallel rake bodies 331, each with a width of 30-60 cm. This effectively removes the coke lumps 4 and increases the area cleared in a single pass, thereby improving work efficiency.
[0031] In this invention, the travel of the telescopic robotic arm 32 is 120-180cm, ensuring the working stroke during desiccation.
[0032] In this invention, the movable fixed bracket 31 is also equipped with a camera, which can facilitate the observation of the distribution of the coke block 4 and the coke clearing process.
[0033] In this invention, each of the free ends of the two hydraulic telescopic support columns 36 is provided with a rubber pad to prevent slippage and ensure stable support of the movable fixed bracket 31.
[0034] In this utility model, there are two lifting winches 22, which are respectively located on both sides of the lower end of the lifting beam 12. They are used to control the lifting of the two lifting wire ropes 21. The two lifting wire ropes 21 can be relatively limited by the cable guide to ensure lifting stability.
[0035] This utility model has a simple structure. By setting up a translation and fixing mechanism, a lifting mechanism and a coke removal mechanism, it can quickly and stably complete the coke removal work without the need for manual entry into the furnace, thus reducing the labor intensity of workers, avoiding the safety problems associated with manual coke removal, and improving the efficiency of coke removal work.
[0036] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
