Technical Field
[0001] This utility model relates to the field of gasifier technology, specifically to a gasifier equipped with a biomass pellet burner. Background Technology
[0002] The ash produced after burning biomass pellet fuel is rich in mineral nutrients such as potassium, calcium, and magnesium. This ash can be returned to the field as a high-quality organic fertilizer, which can improve soil structure, increase soil fertility, and enhance the soil's water and fertilizer retention capacity, thus benefiting crop growth.
[0003] However, these waste residues usually require manual cleaning, which is tedious and consumes a lot of manpower and time. This not only increases the labor intensity of workers, but also poses certain safety hazards due to the high temperature inside the furnace during the cleaning process. Utility Model Content
[0004] In view of the problems existing in the current biomass pellet combustion gasifier, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a biomass pellet combustion gasifier that solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A biomass pellet gasifier includes a combustion chamber and a combustion fan. The combustion fan is located on one side of the combustion chamber. An opening is formed on one side of the lower end of the combustion chamber. A first U-shaped plate is slidably disposed on the inner side of the opening. A second U-shaped plate is fixedly disposed on the outer side of the first U-shaped plate. An ash-receiving plate is disposed between the first and second U-shaped plates. A first sliding groove and a second sliding groove are respectively formed on both sides of the first and second U-shaped plates. A slider is slidably disposed on the inner side of each of the first sliding grooves. A U-shaped block is slidably disposed between the two sides of the second sliding grooves. A shaft pin is rotatably disposed inside both ends of the ash-receiving plate. The two ends of the shaft pin are rotatably connected to the inner walls of the corresponding slider and the U-shaped block, respectively. A sealing plate is fixedly disposed on the outer side of the second U-shaped plate. A transmission mechanism for moving the U-shaped block is disposed on the inner side of the upper end of the sealing plate.
[0008] Preferably, the transmission mechanism includes an internally threaded tube and a threaded rod. The internally threaded tube is rotatably disposed on the inner wall of the second U-shaped plate, and the threaded rod is threadedly sleeved inside the internally threaded tube. The lower end of the threaded rod is fixedly connected to the U-shaped block, and the lower end of the internally threaded tube is fixedly sleeved on the first bevel gear. A transmission rod is rotatably disposed inside the upper end of the sealing plate. A second bevel gear is fixedly sleeved on the end of the transmission rod near the first bevel gear. The first bevel gear and the second bevel gear are meshed and connected. A motor is fixedly disposed on the outer side of the upper end of the sealing plate, and the output end of the motor is fixedly connected to one end of the transmission rod.
[0009] Preferably, the motor is fixedly connected to the sealing plate via a support frame.
[0010] Preferably, the sealing plate has a first threaded hole at both ends, and the outer wall of the combustion chamber has a second threaded hole at a position corresponding to the first threaded hole.
[0011] Preferably, the longitudinal sections of the first U-shaped plate and the opening are both rectangular.
[0012] Preferably, the base plate of the combustion fan is provided with a support seat.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] This invention allows for the automatic dumping of ash residue by releasing the limiting position of the sealing plate and pulling it away from the combustion chamber. The motor then drives the transmission rod to rotate, causing the second bevel gear to rotate the first bevel gear, which in turn rotates the internally threaded tube. This internally threaded tube then drives the non-rotating threaded rod to move vertically, causing the U-shaped block to move upwards. This, in turn, causes the slider to slide along the first groove, resulting in the ash-collecting plate rotating at an angle. This allows for the automatic dumping of the ash residue, significantly saving manpower. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] This utility model discloses a gasifier equipped with a biomass pellet burner.
[0023] Reference Figures 1-3 A biomass pellet gasifier includes a combustion chamber 1 and a combustion fan 2. The combustion fan 2 is located on one side of the combustion chamber 1. A support base 3 is provided on the bottom plate of the combustion fan 2 to support the combustion fan 2. An opening is provided on one side of the lower end of the combustion chamber 1. A first U-shaped plate 5 is slidably arranged inside the opening. The longitudinal section of both the first U-shaped plate 5 and the opening is rectangular, so that the first U-shaped plate 5 cannot rotate, i.e., it can slide stably. A second U-shaped plate is fixedly arranged on the outer side of the first U-shaped plate 5. A ash-receiving plate 8 is provided between the first U-shaped plate 5 and the second U-shaped plate 7. The first U-shaped plate 5 and the second U-shaped plate 7 are respectively provided with a first sliding groove and a second sliding groove on both sides. A slider 6 is slidably provided on the inner side of the first sliding groove on both sides. A U-shaped block 9 is slidably provided between the second sliding groove on both sides. A shaft pin 10 is rotatably provided inside both ends of the ash-receiving plate 8. The two ends of the shaft pin 10 are rotatably connected to the inner wall of the corresponding slider 6 and the U-shaped block 9 respectively. A sealing plate 11 is fixedly provided on the outer side of the second U-shaped plate 7.
[0024] Reference Figures 1-3The upper inner side of the sealing plate 11 is provided with a transmission mechanism that drives the U-shaped block 9 to move. The transmission mechanism includes an internally threaded tube 12 and a threaded rod 17. The internally threaded tube 12 is rotatably disposed on the inner wall of the second U-shaped plate 7. The threaded rod 17 is threadedly sleeved inside the internally threaded tube 12. The lower end of the threaded rod 17 is fixedly connected to the U-shaped block 9. The lower end of the internally threaded tube 12 is fixedly sleeved on the first bevel gear 13. The upper inner side of the sealing plate 11 is rotatably provided with a transmission rod 15. The end of the transmission rod 15 near the first bevel gear 13 is fixedly sleeved on the second bevel gear 14. The first bevel gear 13 and the second bevel gear 14 are meshed and connected. The upper outer side of the sealing plate 11 is fixedly provided with a motor 16. The output end of the motor 16 is fixedly connected to one end of the transmission rod 15. The motor 16 is fixedly connected to the sealing plate 11 through a support frame, so that the connection between the motor 16 and the sealing plate 11 is more stable.
[0025] Reference Figures 1-3 Both ends of the sealing plate 11 are provided with first threaded holes, and the outer wall of the combustion chamber 1 is provided with second threaded holes at positions corresponding to the first threaded holes, so as to facilitate the use of bolts to fix the sealing plate 11 to the outside of the combustion chamber.
[0026] In this invention, when in use, the limiting position of the sealing plate 11 is released, and then the sealing plate 11 is pulled away from the combustion chamber 1. This allows the ash receiving plate 8 to be pulled out of the combustion chamber 1. Then, the motor 16 drives the transmission rod 15 to rotate, causing the second bevel gear 14 to drive the first bevel gear 13 to rotate, which in turn causes the internal threaded tube 12 to rotate. The internal threaded tube 12 drives the non-rotating threaded rod 4 to move vertically, which causes the U-shaped block 9 to move upward, thereby causing the slider 6 to slide along the first sliding groove. This causes the ash receiving plate 8 to rotate in an inclined state, which can automatically dump the ash residue after combustion, greatly saving manpower.
[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
