[0014] Preferably, the isolation plate is obliquely arranged inside the boiler, and the isolation plate divides the interior of the boiler into two parts, the upper part is the evaporation chamber, and the lower part is the combustion chamber.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, by setting the bottom plate and the ash guide cover, the bottom plate is dragged by the handle to open the bottom of the boiler, and the coal ash on the bottom plate falls onto the ash guide cover and is guided out through the through holes on the ash guide cover, which replaces the existing manual ash cleaning method, reduces the labor burden and improves work efficiency;

While the scraper cleans the inner wall of the boiler, the nozzle can cooperate with the cleaning brush to clean the inner wall of the boiler. The agglomerates scraped out by the scraper are guided out through the through holes on the ash guide cover to achieve dry and wet separation. While cleaning the agglomerates on the inner wall of the boiler, the inner wall of the boiler can be cleaned, thereby further improving the cleaning effect.

[0019] In the above scheme, a hydraulic cylinder and a telescopic rod are set, and the hydraulic cylinder drives the ash guide hood to rise until the ash guide hood rises to the position of the isolation plate. Since the isolation plate is set to be inclined, as the ash guide hood continues to rise, the ash guide hood tilts. At this time, one telescopic rod contracts and the other telescopic rod extends, so that the ash guide hood tilts and remains tilted, and fits with the bottom of the isolation plate. At this time, the scraper fits with the bottom of the isolation plate. At this time, the scraper is driven to rotate by the motor to clean the bottom of the isolation plate. The cleaned agglomerates are discharged from the through holes on the ash guide hood, reducing the agglomerates on the inner wall of the combustion chamber, solving the problem that the existing equipment can only clean the inner wall of the boiler and the cleaning effect is poor, and further improving the combustion efficiency.

A return spring is arranged inside the telescopic rod 10, and the ash guide cover 7 is driven to rise by the hydraulic cylinder 5 until the ash guide cover 7 rises to the position of the isolation plate. As the ash guide cover 7 continues to rise, the ash guide cover 7 is pushed to rotate by the inclined isolation plate. At this time, one telescopic rod 10 contracts and the other telescopic rod 10 extends to tilt the ash guide cover 7 so that the ash guide cover 7 fits with the bottom of the isolation plate, which is convenient for cleaning the bottom of the isolation plate in the next step and improves the cleaning effect.

[0033] The technical solution provided by the present invention is to set a bottom plate and an ash guide cover, and to open the bottom of the boiler by dragging the bottom plate with a handle, so that the coal ash on the bottom plate falls onto the ash guide cover and is guided out through the through holes on the ash guide cover, thereby replacing the existing manual ash cleaning method, reducing the labor burden and improving work efficiency.

[0034] By arranging a hydraulic cylinder, a motor and a scraper, the hydraulic cylinder drives the ash guide cover to rise, and the motor drives the scraper to rotate, so that the scraper cleans the inner wall of the boiler, removes the agglomerates on the inner wall of the boiler, and the cleaned agglomerates are guided out through the through holes on the ash guide cover, so that the inner wall of the boiler can be cleaned at the same time during the ash cleaning process, replacing the cleaning method of workers, improving the cleaning effect, and further improving the combustion efficiency;

While cleaning the agglomerates on the inner wall of the boiler, the inner wall of the boiler can be cleaned, thereby further improving the cleaning effect.

[0036] By setting a hydraulic cylinder and a telescopic rod, the ash guide hood is driven to rise by the hydraulic cylinder until it rises to the position of the isolation plate. Since the isolation plate is set to be inclined, as the ash guide hood continues to rise, the ash guide hood tilts. At this time, one telescopic rod contracts and the other telescopic rod extends, so that the ash guide hood tilts and remains tilted and fits with the bottom of the isolation plate. At this time, the scraper fits with the bottom of the isolation plate. At this time, the scraper is driven to rotate by a motor to clean the bottom of the isolation plate. The cleaned agglomerates are discharged from the through holes on the ash guide hood, reducing the agglomerates on the inner wall of the combustion chamber, solving the problem that the existing equipment can only clean the inner wall of the boiler and the cleaning effect is poor, and further improving the combustion efficiency.
