[0021] In this embodiment, the grate body 1 is the main part of the chain grate, which is responsible for carrying and moving the fuel combustion furnace 2 to provide the environment required for combustion. The boiler body 3 is used to collect and utilize the heat generated by combustion. The main function of the scraper 5 is to scrape off the accumulated dust on the surface of the grate body 1. The scraper groove can better clean the dust and impurities on the grate body 1. The protective shell 7 plays a protective role to prevent external factors from damaging the equipment. The cooling component is used to reduce the temperature of dust attached to the surface of the grate body 1, which helps to prevent dust from sticking due to high temperature, thereby reducing the possibility of blockage.

[0022] In a further preferred embodiment of the utility model, the cooling component includes a fan 8, an exhaust pipe 9 and a cooling pipe 10, the fan 8 is fixedly mounted on the protective shell 7, the exhaust pipe 9 is fixedly mounted at the exhaust end of the fan 8 and extends through the protective shell to above the scraper, the cooling pipe 10 is fixedly mounted at the end of the exhaust pipe 9, and the cooling pipe is provided with a plurality of air outlets.

[0023] In this embodiment, the fan 8 serves as the power source of the entire cooling assembly and is fixedly mounted on the protective shell 7. Its main function is to generate wind flow and direct the wind flow to the parts that need cooling through the exhaust pipe 9. The design of the air outlet enables the wind flow to blow more evenly to various parts of the grate body 1, ensuring the uniformity and consistency of the cooling effect, making it easier to scrape the slag after cooling, and at the same time reducing the damage of the high-temperature slag to the scraper 5 and the brush plate 6.

[0024] In a further preferred embodiment of the utility model, a limiting frame 15 located below the scraper is provided in the protection shell 7, a collecting box 16 is movably installed in the limiting frame 15, and two handles are provided on the collecting box 16.

[0025] In this embodiment, the limit frame 15 not only plays the role of fixing and supporting, but more importantly, it provides a stable activity space for the collection box 16, and the collection box 16 can be easily taken out or put in. This design makes it easier and more efficient to clean the ash and dust on the grate body 1. When cleaning, the staff only needs to hold the two handles on the collection box 16 to easily take it out of the limit frame 15, and then pour out the accumulated ash and dust. This design not only facilitates the cleaning work, but also effectively prevents the scattering of ash and dust, and keeps the working environment clean.

[0026] In a further preferred embodiment of the utility model, an air inlet pipe 11 is fixedly installed at the air inlet end of the fan 8, a metal pipe 12 is fixedly installed on the air inlet pipe 11, and an ice storage bin 13 is fixedly installed on an outer wall of one side of the protective shell 7. The ice storage bin 13 is fixedly sleeved outside the metal pipe 12, and the ice storage bin 13 is filled with ice cubes.

[0027] In this embodiment, the role of the metal tube 12 lies in its excellent thermal conductivity, which enables rapid heat exchange, and the introduction of the ice storage bin 13 is an important improvement in the cooling effect. The ice storage bin 13 is fixedly mounted outside the metal tube 12, and is filled with ice cubes. These ice cubes can continuously absorb the heat on the metal tube 12 through their low-temperature characteristics, and convert it into latent heat of melting of ice, thereby further reducing the inlet air temperature. When the fan 8 is working, the outside air enters through the air inlet pipe 11, is cooled by the ice cubes when passing through the metal tube 12, and then enters the fan 8 for circulation. In this way, the wind that has been cooled can more effectively reduce the dust temperature on the surface of the grate body 1.

[0028] In a further preferred embodiment of the utility model, a filter box 14 is installed at the air inlet end of the metal tube 12, and a limiting cylinder is installed on the internal thread of the filter box 14. An isolation net is provided on the limiting cylinder, and the limiting cylinder is filled with filter material.

[0029] In this embodiment, the main function of the isolation net is to prevent larger impurities or foreign objects from entering the metal tube 12, thereby protecting the normal operation of the fan 8 and the cooling component. The filter material can effectively remove tiny impurities such as dust and particulate matter in the air, ensuring that the air entering the fan 8 and the cooling component is clean.

[0030] In a further preferred embodiment of the utility model, two sliders 17 are fixedly installed at the bottom of the protective shell 7, and the two sliders 17 are movably sleeved with the same base, and a baffle 18 is fixedly installed on the top of the base. An opening is provided on one side of the protective shell 7, and the baffle 18 can be attached to the outside of the opening.

[0031] In this embodiment, the slider 17 enables the entire protective shell 7 and its internal components to be easily moved and positioned on the base. The cooperation between the slider 17 and the base ensures both the smoothness of movement and the accuracy of positioning. The baffle 18 not only plays a protective role to prevent external objects or personnel from accidentally contacting the equipment inside the protective shell 7, thereby improving safety, but the baffle 18 can also be attached to the outside of the opening to play a sealing and dust-proof role. When it is necessary to maintain or inspect the equipment inside the protective shell 7, it only needs to remove the baffle 18 from the outside of the opening to conveniently operate through the opening.

[0032] In a further preferred embodiment of the utility model, an observation window 19 is provided on the baffle 18, a clamping rod is hinged on one side of the protective shell 7 close to the baffle 18, a clamping ring is fixedly installed on the baffle 18, and the clamping rod can extend into the clamping ring.

[0033] In this embodiment, the clamping rod can be conveniently extended into the clamping ring when needed, thereby locking the baffle 18. When the clamping rod is fully inserted into the clamping ring, the protective shell 7 is firmly fixed on the baffle 18, effectively preventing it from accidentally opening or moving during the operation of the equipment.

[0034] In summary, compared with the related art, the present device can increase the protection effect of the present device by providing the protective shell 7 and the baffle 18, and can scrape the impurities attached to the surface of the grate body 1 by providing the scraper 5 and the brush plate 6 to prevent the accumulation of impurities and blockage, and can cool the grate body 1 by providing the fan 8 in conjunction with the exhaust pipe 9 and the cooling pipe 10, so that the hardening of the impurities is more convenient for the subsequent scraping work, and can further increase the cooling effect by providing the metal pipe 12 and the ice storage bin 13.
