Biomass pellet stove can make full use of biomass energy to replace coal, reduce CO2 and SO2 emissions, which is beneficial to environmental protection and control of greenhouse gas emissions, slow down climate change and reduce the occurrence of natural disasters.

[0003] However, most of the current traditional biomass pellet stove designs only have a single combustion chamber, where the oxygen supply is often insufficient during the combustion of pellets, resulting in low combustion efficiency, incomplete combustion of pellets, and the generation of a large amount of unburned carbon residue and pollutants. However, there are also blowers that add oxygen, and in this process, the wind force generated by the blower will cause the biomass pellets to fly around, and the burning ash will also spread everywhere. In addition, this design cannot optimize the combustion of different types of biomass pellets, thus affecting the overall performance and thermal efficiency of the stove. Utility Model Content

Electric push rods 13 are fixed on both sides of the outer shell 1, and the telescopic ends of the electric push rods 13 penetrate the outer shell 1. Sealing baffles 14 are arranged on one side of the main combustion chamber 2 and the auxiliary combustion chamber 5, and the telescopic ends of the electric push rods 13 are fixedly connected to one side of the sealing baffle 14. Two scrapers 15 are fixed on one side of the sealing baffle 14, and a temperature sensor 16 is fixed on one side of the sealing baffle 14.

[0027] The biomass is first crushed by the crushing device 10, so that the biomass can be more delicate, which is conducive to more complete combustion in the subsequent combustion process. After crushing, the biomass is transported to the quantitative box 8, and the pressure sensor in the quantitative box 8 is used to judge the amount of one-time input to avoid accumulation and difficulty in combustion caused by excessive input. Then the biomass is allowed to enter the main combustion chamber 2, and then a certain amount of oxygen is transported into the main combustion chamber 2 through the main oxygen supply box 3 and the main connecting pipe 4. When the oxygen in the main combustion chamber 2 is burned out, the sealing baffle 14 is driven to move by the telescopic end of the electric push rod 13, so that the scraper 15 can move, so that the burned biomass can be pushed to the auxiliary combustion chamber 5. In this process, the ash produced by the combustion can also be The dust is scraped off, making the furnace cleaner and tidier to avoid affecting the next use. Then oxygen is transported through the auxiliary oxygen supply box 6 and the auxiliary connecting pipe 7, so that the biomass can be burned again. The main combustion chamber 2 and the auxiliary combustion chamber 5 have different oxygen supply amounts to ensure that the particulate matter is fully burned at different stages, so that the biomass is fully burned, which improves thermal efficiency, saves raw materials, and reduces production costs. Heat is generated by the heating wire in the guide plate 11, so that the biomass can be preheated and dried first, so that it can burn faster. The delay column 12 can slow down the flow speed of the biomass, which is conducive to more complete drying. The temperature during combustion can be monitored by the temperature sensor 16 to avoid excessive temperature and improve safety.

[0028] Embodiment 2:

[0029] like Figure 1-Figure 5As shown, a biomass pellet stove disclosed in Example 2 of the utility model has a structure that is basically the same as that in Example 1, except that a first discharge pipe 17 is connected and fixed to the top of the main combustion chamber 2, and second discharge pipes 18 are respectively connected and fixed to the two sides of the auxiliary combustion chamber 5, and a valve is arranged inside the second discharge pipe 18; one end of the second discharge pipe 18 is connected and fixed to the first discharge pipe 17, a purification box 19 is arranged inside the outer shell 1, and the top of the first discharge pipe 17 is connected and fixed to the bottom of the purification box 19; three adsorption filters 20 are detachably arranged inside the purification box 19, an exhaust pipe 21 is connected and fixed to the top of the purification box 19, one end of the exhaust pipe 21 passes through the outer shell 1, and a collecting frame 22 is arranged on the inner bottom surface of the outer shell 1, and the collecting frame 22 is located directly below the slag outlet of the auxiliary combustion chamber 5.

[0030] The flue gas generated during the combustion in the main combustion chamber 2 and the auxiliary combustion chamber 5 can be discharged into the purification box 19 for purification and filtration through the first discharge pipe 17 and the second discharge pipe 18 respectively. The generated flue gas can be filtered more cleanly through the adsorption filter 20, and then the filtered gas is discharged to the surrounding environment through the exhaust pipe 21. The generated waste residue can be collected through the collection frame 22, which is conducive to subsequent centralized treatment.

[0031] Embodiment three:

[0032] like Figure 1-Figure 5 As shown, a biomass pellet stove disclosed in Example 3 of the utility model has a structure that is basically the same as that in Example 2, except that a vacuum cleaner 23 is fixed to one side of the inner wall of the outer shell 1, and the vacuum cleaner 23 corresponds to the collecting frame 22. A heat dissipation hole 24 is opened on one side of the outer shell 1, and a dustproof net 25 is fixed inside the heat dissipation hole 24. A pressure sensor is arranged inside the quantitative box 8, and the quantitative box 8 is connected to the delivery box 9 by a conveying pipe. An electric valve is arranged inside the conveying pipe, and the pressure sensor and the electric valve are electrically connected to the external control device.

[0033] The dust generated when the waste residue is discharged can be absorbed by the vacuum cleaner 23 to prevent the dust from spreading inside the shell 1 and causing difficulty in cleaning. The heat dissipation holes 24 can balance the heat in the shell 1 to avoid excessive heat. While dissipating heat, the dustproof net 25 can prevent dust from entering and waste residue dust from leaking out.

[0034] The specific scheme is as follows: the staff first places the biomass into the delivery box 9, and then crushes the biomass through the crushing device 10, so that the biomass can be more delicate, which is conducive to more complete combustion in the subsequent combustion process. After crushing, the biomass is transported to the quantitative box 8, and the pressure sensor in the quantitative box 8 is used to judge the amount of one-time input to avoid accumulation and difficulty in combustion caused by excessive input. Then the biomass is allowed to enter the main combustion chamber 2, and then a certain amount of oxygen is transported into the main combustion chamber 2 through the main oxygen supply box 3 and the main connecting pipe 4. When the oxygen in the main combustion chamber 2 is burned out, the electric push rod 13 is extended. The contracted end drives the sealing baffle 14 to move, and then the scraper 15 can move, so that the burned biomass can be pushed to the auxiliary combustion chamber 5. In this process, the dust produced by the combustion can also be scraped off, so that the furnace is cleaner and tidier to avoid affecting the next use. Then oxygen is transported through the auxiliary oxygen supply box 6 and the auxiliary connecting pipe 7, so that the biomass can be burned again. The main combustion chamber 2 and the auxiliary combustion chamber 5 have different oxygen supply amounts to ensure that the particulate matter is fully burned at different stages, so that the biomass is fully burned, which improves thermal efficiency, saves raw materials, and reduces production costs.
