DETAILED DESCRIPTION

[0017] Please refer to the attached Figure 1-Figure 5 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0018] The utility model proposes an automatic slag removal mechanism for a biomass boiler. Before use, the upper sides of a group of movable plates 8 are in a flush state, a group of movable plates 8 form a support plate, and the output end of the electric push rod 9 is in a fully extended state. When using the device, the device is installed at the lower end of the discharge port of the boiler through the installation frame 1, and water is poured into the heat absorption box 6. The slag slides along the collection cover 2 and falls on the upper side of a group of movable plates 8. The heat of the slag is transmitted to the heat absorption box 6 through the discharge pipe 16. The heat of the slag is absorbed by the water, which can not only cool the slag, but also the water in the heat absorption box becomes hot water after absorbing heat, which is used as a heat source for other processes, so as to achieve the purpose of heat source recovery and utilization. After a pair of radiation sensors 7 detect that the slag has accumulated to a certain height, the electric push rod 9 is started, and the output end of the electric push rod 9 retracts to drive the slide plate 12 to slide. The slide plate 12 drives the trapezoidal slide bar 11 to slide along the trapezoidal groove plate 10 in the direction close to the electric push rod 9. The plate 12 drives the corresponding sliding column 13 to slide through a group of sliding grooves 14, and a group of sliding columns 13 drives the corresponding L-shaped rods 15 to swing, and a group of L-shaped rods 15 drives the corresponding movable plates 8 to swing. When the output ends of the electric push rods 9 are all retracted, the electric push rods 9 stop. At this time, a group of movable plates 8 are in a parallel relationship with each other (the swing angle of a group of movable plates 8 is 30-45°), and the slag on a group of movable plates 8 slides into the drawer 5 along a group of movable plates 8. After a short period of rest until the slag has all fallen off, the electric push rods 9 are started again, and the output ends of the electric push rods 9 extend to make a group of movable plates 8 form a support plate again to temporarily store the slag again. When the slag accumulates to a certain extent, the drawer 5 is pulled out and all the slag in the drawer 5 is poured out, replacing the traditional purpose of manually cleaning the slag. The slag in the drawer is poured out and processed together, which is more convenient to process. The device can clean the slag and recover the heat of the slag, which is multi-purpose.
