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

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figures 1-6 As shown, a heavy-duty scraper automatic slag removal device for a biomass burner includes: a housing 1, a storage bin 11 fixedly connected to the bottom of the higher side of the housing 1, a sealing door 12 rotatably connected to the bottom of the storage bin 11 via a hinge, and a drain valve 13 located on the outside of the housing 1 near the bottom; and a slag removal assembly located inside the housing 1 for scraping off the slag inside the housing 1.

[0026] When in use, cooling water is injected into the box 1. The residue after the biomass material is burned will fall into the box 1. The cooling water will cool the residue. The residue inside the box 1 will be cleaned by the slag removal component and transported to the storage bin 11. The residue will be temporarily stored in the storage bin 11. The water inside the box 1 can be drained after the drain valve 13 is opened.

[0027] Example 2

[0028] Based on Embodiment 1, the slag removal assembly includes: a rotating roller 2, a sprocket 21, a transmission chain 22, scrapers 23, and a reduction motor 24. Two rotating rollers 2 are rotatably connected between the inner walls of opposite sides of the housing 1. Two sprockets 21 are fixedly connected to the outside of each of the two rotating rollers 2. A transmission chain 22 is connected between the two sprockets 21 on the same side. Several scrapers 23 are fixedly installed between the two transmission chains 22. A reduction motor 24 is fixedly installed on the outside of the housing 1 near the lower side. One end of the drive shaft of the reduction motor 24 is connected to the rotating shaft of the rotating roller 2 on the adjacent side. A limiting roller 25 and several support seats 26 are rotatably connected between the inner walls of opposite sides of the housing 1. The limiting roller 25 and the support seats 26 are located between the two sprockets 21.

[0029] When cleaning the residue inside the box 1, the geared motor 24 is started to drive the connected rotating roller 2 to rotate. When the rotating roller 2 rotates, it drives the two sprockets 21 to rotate. When the sprockets 21 rotate, they mesh with the two transmission chains 22, thereby driving the two transmission chains 22 to move synchronously. When the transmission chains 22 move, they drive the external scraper 23 to move. The limiting roller 25 presses the lower section of the transmission chain 22 so that the lower part of the transmission chain 22 fits the shape of the box 1. The support seat 26 is used to support the upper section of the transmission chain 22 so that the upper section of the transmission chain 22 adapts to the shape of the box 1. When the scraper 23 moves, it carries the residue out of the box 1. The residue moves along the bottom of the box 1 to the storage bin 11, thereby cleaning the residue out of the box 1.

[0030] The bottom of the sealing door 12 is fixedly equipped with a balance plate 3, and the top of the balance plate 3 is fixedly equipped with a counterweight 31. The residue entering the storage bin 11 is temporarily stored in the storage bin 11. When the residue in the storage bin 11 accumulates to a certain level, the weight of the residue in the storage bin 11 is greater than the weight of the balance plate 3 and the counterweight 31, causing the balance plate 3 to drive the sealing door 12 to rotate clockwise. The sealing door 12 moves away from the bottom of the storage bin 11, and the residue in the storage bin 11 is discharged and falls out. The counterweight 31 can be replaced, thereby controlling the amount of residue that can be stored in the storage bin 11.

[0031] Example 3

[0032] Based on Embodiment 1, a connecting frame 4 is provided inside the box 1 near the higher side. The rotating roller 2 on the higher side is rotatably connected to the inner walls of the connecting frame 4 on opposite sides. Guide grooves 41 are respectively opened on the inner walls of opposite sides of the box 1. Guide blocks 42 are fixedly connected to the inner walls of opposite sides of the connecting frame 4. The two guide blocks 42 are respectively located inside the two guide grooves 41. A baffle 5 is fixedly installed between the inner walls of opposite sides of the box 1 near the connecting frame 4. A screw 51 is threadedly connected to the baffle 5. The bottom end of the screw 51 is rotatably connected to the connecting frame 4. An adjusting wheel 52 is fixedly connected to the top end of the screw 51.

[0033] When adjusting the tension of the transmission chain 22, manually rotate the adjusting wheel 52 to drive the screw 51 to rotate. The screw 51 engages with the baffle 5, which in turn drives the connecting frame 4 to move. When the connecting frame 4 moves, it drives the guide blocks 42 on both sides to move along the inside of the guide groove 41, thereby restricting the rotating roller 2 so that it can only move horizontally along the guide groove 41. By controlling the rotation direction of the adjusting wheel 52, the connecting frame 4 can be controlled to move up or down, thereby adjusting the distance between the two rotating rollers 2, thus adjusting the tension of the transmission chain 22.
