Description

Technical Field

[0001] This utility model relates to the field of waste incinerator technology, and in particular to an ash removal device for waste incinerators. Background Technology

[0002] A waste incinerator is an environmentally friendly device that uses high temperatures to burn waste gas, waste liquid, solid waste, fuels, medical waste, household waste, animal carcasses, etc., to reduce or minimize their quantity. During operation, due to the unpredictable composition of waste, slag and ash easily form in the furnace. These substances lower the furnace temperature, affect combustion efficiency, and can even cause the equipment to shut down. Therefore, an ash removal device is needed to remove these slag and ash deposits to restore furnace temperature and combustion efficiency, ensuring the normal operation of the equipment.

[0003] A search revealed that patent document CN221592895U discloses an ash removal device for a waste incinerator. The device uses a telescopic platform to transport the ash removal components into the incinerator, and then a drive motor drives the cleaning brush to perform circumferential motion to remove ash from the inner wall of the incinerator, thereby reducing the proportion of dust in the flue gas during incineration and protecting the environment.

[0004] In actual use, the ash removal device described above uses a brush to clean back and forth by moving up and down and rotating. However, it cannot handle hardened slag through the brushing action. Moreover, for incinerators with internal slag-turning structures, the ash removal device cannot be directly used inside the waste incinerator, which affects normal operation. For example, the slag-turning component mentioned in the patent document with publication number CN221172252U. Utility Model Content

One end of the fastening bolt is pressed against the outer wall of the inner tube, and the ring and the fixed tube are fixed on the mating ring by setting the fastening bolt.

[0010] Preferably, a burner is fixedly embedded in the outer wall of the incinerator body, and the burner plays the role of igniting and burning the waste.

[0011] Preferably, an air inlet pipe is fixedly connected to the outer wall of the incinerator body, and a blower is fixedly connected to one end of the air inlet pipe. The blower sends outside air into the incinerator body to improve combustion efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-4As shown, an ash removal device for a waste incinerator is disclosed, comprising an incinerator body 1, a feed pipe 2 fixedly connected to the outer wall of the incinerator body 1, a burner 3 fixedly embedded in the outer wall of the incinerator body 1, a slag discharge pipe 4 fixedly connected to the bottom of the incinerator body 1, a sealing cap 5 threadedly connected to the inner wall of the bottom of the slag discharge pipe 4, the sealing cap 5 sealing the bottom of the slag discharge pipe 4, and opening it during subsequent slag discharge and ash removal.

[0024] An air inlet pipe 6 is fixedly connected to the outer wall of the incinerator body 1. A blower is fixedly connected to one end of the air inlet pipe 6. A slag-turning plate 7 is installed inside the incinerator body 1. The slag-turning plate 7 can be rotated by an existing drive mechanism, which is located at the bottom of the incinerator body 1. Multiple slag discharge holes are evenly opened on the outer wall of the slag-turning plate 7. An exhaust pipe 8 is fixedly connected to the outer wall of the incinerator body 1.

[0025] The top of the incinerator body 1 is provided with a docking groove 9, and the top of the incinerator body 1 is fixedly connected with an internal thread docking ring 10. When the fixed pipe 12 is not located inside the incinerator body 1 and the incinerator body 1 does not need to be de-ashed, the internal thread docking ring 10 is sealed by the existing external thread cover. A ring 11 is placed on the top of the internal thread docking ring 10, and a fixed pipe 12 is fixedly connected to the inner wall of the ring 11. A sliding hole is provided on the top of the fixed pipe 12, and an inner pipe 13 is slidably connected to the inner wall of the sliding hole.

[0026] The outer wall of the fixed tube 12 has an installation hole, and the inner wall of the installation hole is threaded with a fastening bolt 17. One end of the fastening bolt 17 is pressed against the outer wall of the inner tube 13. The fastening bolt 17 fixes the ring 11 and the fixed tube 12 to the top of the docking ring 10 without the need to hold the fixed tube 12. The outer walls of the ring 11 and the internally threaded docking ring 10 are both threaded. The inner walls of the two threaded holes are threaded with the same locking bolt 14. The bottom outer wall of the inner tube 13 is fixedly fitted with a piston 18. The outer wall of the piston 18 is slidably connected to the inner wall of the fixed tube 12. The piston 18 prevents the liquid desiccant from flowing upward into the interior of the fixed tube 12.

[0027] The incinerator body 1 is equipped with a flushing mechanism, which includes a flat nozzle 15. The bottom of the fixed pipe 12 is fixedly connected to the top of the flat nozzle 15. Multiple water outlets 16 are evenly opened on the outer walls of the fixed pipe 12 and the flat nozzle 15. The multiple water outlets 16 on the flat nozzle 15 spray liquid ash removal agent to clean the slag turning plate 7. The top of the inner pipe 13 is fixedly connected to a water pipe, and one end of the water pipe is fixedly connected to a water pump. When the water pump operates, it transports the liquid ash removal agent in the existing container through the inner pipe 13 to the fixed pipe 12. The liquid ash removal agent includes various acids, alkalis, salts, etc., which soften, decompose or dissolve the slag and ash, thereby achieving the purpose of cleaning.

[0028] Working principle: When cleaning the slag and ash buildup on the inner wall of the incinerator body 1, the burner 3 stops operating, and the feed pipe 2 stops feeding waste. The top of the internal threaded coupling ring 10 is exposed, and then the fixed pipe 12 is inserted into the incinerator body 1 through the internal threaded coupling ring 10. The water pump operates to transport the liquid ash removal agent in the existing container through the inner pipe 13 to the fixed pipe 12. The impact generated by the water flow prevents the inner pipe 13 from moving up and down in the fixed pipe 12 through the fastening bolt 17, and the fastening bolt 17 can be rotated to release the ash removal agent. The position of the inner tube 13 is fixed, and the inner tube 13 moves up and down inside the fixed tube 12. The piston 18 moves by moving the inner tube 13, and at the same time changes the number of water outlets 16 that can be discharged, thereby changing the water pressure of the liquid ash remover when it is discharged. The fewer the number of water outlets 16, the greater the water pressure of the liquid ash remover, which in turn effectively cleans the inner wall of the incinerator body 1 and the top of the ash-turning plate 7. The sealing cover 5 is opened to expose the bottom of the ash discharge pipe 4 for liquid discharge, and at the same time the inside of the ash discharge pipe 4 is cleaned to prevent slag and ash accumulation.

[0029] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
