DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 9 As shown, a nut biomass pellet integrated combustion furnace with low heat energy loss includes a furnace body 1, a combustion chamber 2 is provided in the furnace body 1, and an ash collection chamber 3 is provided in the furnace body 1 below the combustion chamber 2. In order to facilitate the collection of ashes produced by combustion, a drawer 4 is movably installed in the ash collection chamber 3, and a through opening is provided on the left side of the ash collection chamber 3. The drawer 4 is inserted into the ash collection chamber 3 through the through opening. When the drawer 4 is full of ashes, the drawer 4 can be pulled out of the ash collection chamber 3 for cleaning.

[0035] like Figure 2 and Figure 3 As shown, a grate assembly is provided in the lower end of the combustion chamber 2, and the grate assembly includes a plurality of rotating rods 5 arranged in parallel on the left and right sides and rotatably installed in the lower end of the combustion chamber 2, the rotating rods 5 extend forward and backward, and the two ends of the rotating rods 5 are rotatably connected to the side walls of the combustion chamber 2 through bearings, and the plurality of rotating rods 5 are driven to rotate synchronously by a driving mechanism. Specifically, the front ends of the plurality of rotating rods 5 extend to the outside of the furnace body 1, and the front ends of two adjacent rotating rods 5 are connected by a belt 29, and the front end of one of the rotating rods 5 is also connected to the rotating shaft of the driving motor 6 through a coupling, and the driving motor 6 is installed on the motor mounting frame located on the front side of the furnace body 1 by bolts.

[0036] like Figure 4 As shown, a plurality of movable grate plates 7 evenly spaced along the length direction are welded on the rotating rod 5 located in the combustion chamber 2, and the movable grate plates 7 on two adjacent rotating rods 5 are staggered, so that the plurality of movable grate plates 7 provide support for the biomass particle fuel.

[0037] The driving mechanism drives the movable grate pieces 7 to swing back and forth through the rotating rod 5. During use, the driving motor 6 drives the multiple rotating rods 5 to rotate back and forth, and then the rotating rod 5 drives the movable grate pieces 7 to swing back and forth, and the multiple movable grate pieces 7 drive the bottom of the biomass pellet fuel to fluctuate up and down, so that the ash produced by the combustion can fall down in time, thereby improving the combustion efficiency of the biomass pellet fuel.

[0038] like Figure 5 As shown, in this embodiment, the movable grate plate 7 is provided with a horizontal portion 8, and both ends of the horizontal portion 8 are provided with inclined portions 9, and the inclined portion 9 is arranged to be inclined downward at one end away from the horizontal portion 8. When the movable grate plate 7 is rotated to the left or right to the limit angle, as shown in FIG. Figure 6 As shown, the inclined portion 9 located at the high end of the movable grate piece 7 remains inserted between two adjacent movable grate pieces 7 on the side rotating rod 5, thereby preventing a large longitudinal gap from being generated between the movable grate pieces 7 on two adjacent rotating rods 5 when the movable grate piece 7 swings, causing large pieces of unburned biomass particle fuel to fall into the ash collection chamber 3.

[0039] In addition, a plurality of fixed grate plates 10 are fixedly installed on the inner sides of the left and right side walls of the combustion chamber 2, and are evenly spaced forward and backward along the length direction of the rotating rod 5. The movable grate plates 7 on the rotating rod 5 on the left and right sides are staggered with the fixed grate plates 10 on the corresponding side to further prevent large pieces of biomass particle fuel from falling downward.

[0040] like Figure 3 and Figure 7 As shown, a mounting hole is provided on the right side of the furnace body 1, and an inclined feeding pipe 11 is fixedly installed in the mounting hole, the right end of the feeding pipe 11 is higher than the left end, the high end of the feeding pipe 11 is closed, and the lower end of the feeding pipe 11 extends to the combustion chamber 2 located above the grate assembly, and a movable pipe 12 is slidably sleeved in the feeding pipe 11, and the lower end of the movable pipe 12 extends into the combustion chamber 2. The movable pipe 12 is driven by a power mechanism and moves along the length direction of the feeding pipe 11, and a feeding hopper 13 connected thereto is welded on the top of the feeding pipe 11, and a feeding port 14 for the material in the feeding hopper 13 to fall into is provided on the top wall of the movable pipe 12.

[0041] When adding fuel to the combustion chamber 2, the biomass pellet fuel can be transported to the feeding hopper 13 through the screw feeder, and the biomass pellet fuel enters the movable tube 12 through the feeding hopper 13 and the feed port 14 in turn, and slides into the combustion chamber 2 through the lower end of the movable tube 12; at the same time, the movable tube 12 is driven by the power mechanism to move back and forth left and right along the length direction of the feeding tube 11, so that the biomass pellet fuel is evenly distributed in the combustion chamber 2 along the lower end of the movable tube 12, thereby avoiding a large amount of biomass pellet fuel from accumulating in one place in the combustion chamber, resulting in incomplete combustion, and improving the combustion efficiency of the biomass pellet fuel.

[0042] like Figure 7 and Figure 8 As shown, a movable plate 15 covering the bottom wall is provided in the movable tube 12, and the movable plate 15 is in the shape of a long strip extending in the same direction as the movable tube 12. The movable plate 15 is inclined and lowered on both sides along the width direction. A baffle 16 is welded to the lower end of the movable tube 12, and discharge ports 17 are respectively provided on both sides of the lower end of the movable tube 12 along the width direction. When the biomass pellet fuel enters the movable tube 12 through the hopper 13 and the feed port 14, the biomass pellet fuel first falls onto the movable plate 15, and the biomass pellet fuel slides along the movable plate 15 to the lower end of the movable tube 12, and at the same time, it slides to both sides of the movable plate 15 along the width direction, and finally spreads into the combustion chamber 2 through the discharge ports 17 on both sides of the width of the movable tube 12, further improving the uniformity of the biomass pellet fuel spread in the combustion chamber 2.

[0043] like Figure 8 and Fig. 9 As shown, a guide column 18 is vertically fixedly installed on the bottom wall of the movable tube 12, and the lower end of the guide column 18 is screwed on the bottom wall of the movable tube 12. The guide columns 18 are arranged in two rows front and back along the width direction of the movable tube 12. The movable plate 15 is slidably installed on the plurality of guide columns 18. A stopper 19 is integrally formed on the upper end of the guide column 18. A spring 20 is sleeved on the guide column 18 between the stopper 19 and the movable plate 15 to press the movable plate 15 downward; a strip plate 21 extending in the same direction is fixed or welded to the bottom of the movable plate 15 by bolts, an open groove 22 is provided at the corresponding position of the bottom wall of the movable tube 12 and the strip plate 21, and a plurality of continuous triangular protrusions 23 are provided at the bottom of the strip plate 21 along the length direction, and a support block 24 supported on the bottom of the strip plate 21 is fixed by bolts in the bottom wall of the feeding tube 11, and the top of the support block 24 coincides with the bottom of the strip plate 21.

[0044] When there is no external force, the thrust of the spring 20 makes the bottom of the strip plate 21 close to the top of the support block 24. When the power mechanism drives the movable tube 12 to move back and forth left and right along the length direction of the feeding tube 11, the movable tube 12 drives the movable plate 15 and the strip plate 21 to move left and right relative to the support block 24, and then the support block 24 reacts to the triangular protrusion 23 at the bottom of the strip plate 21 and makes the movable plate 15 vibrate up and down along the guide column 18, thereby prompting the biomass particle fuel to slide down along the movable plate 15, avoiding the accumulation of biomass particle fuel on the movable plate 15, and improving the transportation efficiency of the biomass particle fuel.

[0045] like Figure 1 As shown, the power mechanism includes a screw rod 26 located outside the feeding tube 11 and driven to rotate by a power motor 25. The screw rod 26 extends along the length direction of the feeding tube 11. One end of the screw rod 26 is connected to the rotating shaft of the power motor 25 through a coupling. The power motor 25 is installed on the outer wall of the feeding tube 11 by bolts. The other end of the screw rod 26 is rotatably connected to the outer wall of the feeding tube 11 through a bearing seat. A nut 27 matching the screw rod 26 is fixedly installed on the front side of the movable tube 12 by bolts. A strip hole 28 for the nut 27 to pass through is provided on the front side wall of the feeding tube 11. The power motor 25 drives the screw rod 26 to rotate alternately forward and reverse, and then the screw rod 26 acts on the nut and drives the movable tube 12 to move back and forth along the length direction of the feeding tube 11.
