DETAILED DESCRIPTION
[0023] See also Figs. 1-3 The utility model provides a technical solution: an automatic slag removal biomass pellet burner, comprising a silo 1 and a combustion trough 2. A screw feeder 11 is installed at the lower part of the silo 1, and the upper part of the screw feeder 11 is connected to the interior of the silo 1. After the biomass fuel particles are put into the silo 1, they can enter the screw feeder 11 from the bottom. When the screw feeder 11 is started, the fuel particles will be pushed into the guide pipe 111 connected to its outlet.
[0024] The combustion tank 2 is located outside the silo 1 on the side of the screw feeder 11. The guide pipe 111 connected to the discharge port of the screw feeder 11 is connected to the inside of the combustion tank 2, and a support plate 21 is fixed horizontally at the bottom of the combustion tank 2. The surface of the support plate 21 is evenly provided with through holes 211. When in use, some fuel particles can be placed in the combustion tank 2 above the support plate 21 to ignite it, and then the fuel particles can be slowly and continuously pushed into the combustion tank 2 through the screw feeder 11 for combustion.
[0025] In order to improve the combustion effect, a blast pipe 22 is connected to the side of the combustion tank 2. The blast pipe 22 is connected to the interior of the combustion tank 2, so that when the blast pipe 22 is connected to the blower, air can be introduced into the combustion tank 2, which is conducive to sufficient combustion. A mesh plate 221 is fixed inside the blast pipe 22. The mesh plate 221 is located at the inner end position of the blast pipe 22. Before the air enters the combustion tank 2, it will be diverted by the mesh plate 221 and enter the combustion tank 2 evenly.
[0026] A bottom cover 3 is fixed at the bottom of the combustion tank 2. The residue after the combustion of some fuel particles can fall into the bottom cover 3 through the through hole 211, while the fuel that is not fully burned and still remains in granular form cannot fall into the bottom cover 3. However, the residue will accumulate on the surface of the support plate 21 and cannot enter the bottom cover 3 smoothly. In order to solve this problem, a rotating rod 4 is vertically rotatably installed inside the bottom cover 3, which penetrates the top of the support plate 21. A shift rod 41 close to the surface of the support plate 21 is fixed horizontally on the top of the rotating rod 4. The rotating rod 4 is connected to the stepper motor 43 installed below the bottom cover 3. The stepper motor 43 can be started regularly to drive the rotating rod 4 and the shift rod 41 to rotate, and the top of the support plate 21 in the combustion tank 2 can be shifted, which is conducive to the residue falling smoothly through the through hole 211 to the bottom cover 3 for collection.
[0027] A heat insulating plate 32 is fixed on the surface of the bottom cover 3 above the stepping motor 43 . The stepping motor 43 is mounted on the bottom of the heat insulating plate 32 , which can insulate the stepping motor 43 and enable it to work normally.
[0028] On both sides below the rotating rod 4, there are also fixed paddles 42 close to the bottom surface of the bottom cover 3. At the same time, a slag outlet 31 is provided on the bottom side of the bottom cover 3. The slag outlet 31 is connected to the interior of the bottom cover 3. When the paddle 41 is driven to rotate, the paddle 42 is also driven to rotate, which can scrape the residue entering the bottom cover 3, and finally discharge it from the slag outlet 31 for easy collection.
[0029] When in use, the driving motor of the screw feeder 11 and the stepper motor 43 are connected to the control device, and then powered on to put the biomass fuel particles into the silo 1, and at the same time put a small amount of fuel particles above the support plate 21 in the combustion tank 2 and ignite it. During the combustion operation, the screw feeder 11 is started to rotate at a slow speed, slowly pushing the fuel particles in the silo 1 into the combustion tank 2 through the guide pipe 111, thereby achieving the purpose of continuous combustion. The appliance to be heated can be placed above the combustion tank 2 for use. During the continuous combustion process, the stepper motor 43 is started regularly to drive the rotating rod 4 to rotate, and at the same time drive the dial rod 41 and the dial plate 42 to rotate, and the dial rod When the paddle 42 rotates, the residue that falls into the bottom cover 3 can be moved so that it can be discharged through the slag outlet 31. When the slag outlet 31 is connected to the collection pipe, it can also facilitate the collection of the residue. During operation, in order to make the combustion more complete, a blower can be set and connected to the blast pipe 22 to disperse the air flow into the combustion tank 2 through the through hole 211, so that the fuel particles can be burned more completely.
