Description

Technical Field

[0001] This utility model relates to the field of biomass pellet combustion furnaces, and in particular to a biomass pellet combustion furnace that is easy to ignite. Background Technology

[0002] Biomass pellets are a newly promoted technology that solidifies biomass into a shape and then burns it using traditional coal-fired equipment. Its advantage is that it makes full use of biomass energy to replace coal, reduces emissions of carbon dioxide and sulfur dioxide, and helps control greenhouse gas emissions.

[0003] Biomass pellets are widely used in rural areas, generally as fuel, replacing firewood and coal.

[0004] When using biomass pellets, traditional stoves are still used. However, it has been found that biomass pellets are difficult to ignite because of their high density and small size, making them more difficult to ignite than firewood or honeycomb briquettes. When using dry branches as ignition, the biomass pellets are easily extinguished when they are added. Therefore, a biomass pellet combustion stove that is easy to ignite is proposed.

Detailed Implementation

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] In the attached diagram, all identical reference numerals refer to the same components.

[0030] Example 1

[0031] like Figure 1-3 As shown, this utility model provides a biomass pellet combustion stove that is easy to ignite, including a stove body 1. A table 2 is fixedly installed on the top of the stove body 1. An adding hole is opened on the top of the table 2 and extends into the stove body 1. A sealing plate 3 is detachably installed inside the adding hole. This rural stove is used for heating and boiling water and cooking. A kettle can be placed on the sealing plate 3 to boil water, or a pot can be placed on the sealing plate 3 for cooking. The table 2 is used to place cups, bowls and plates, etc., and can replace the dining table to a certain extent. The specific structure of the table 2 and the sealing plate 3 will not be described in detail here.

[0032] In this embodiment, a furnace bridge 4 is provided inside the furnace body 1. The furnace bridge 4 is a cast iron grid plate with a structure similar to a drainage grid. It is used to support solid fuel, and the gap in the middle is used to allow the ash produced by combustion to pass through. A first door hole 101 and a second door hole 104 are provided on the left side of the furnace body 1. The first door hole 101 and the second door hole 104 are located below and above the furnace bridge 4, respectively. A receiving seat 102 is fixedly provided on the inner bottom wall of the first door hole 101. A first movable door 103 and a second movable door 105 are hinged to the left side of the furnace body 1. The first movable door 103 and the second movable door 105 correspond to the first door hole 101 and the second door hole 104, respectively.

[0033] In this embodiment, a chimney pipe 5 is connected to the right side of the furnace body 1. A lining 14 located inside the furnace body 1 is placed on the top of the furnace bridge 4. The lining 14 is located inside the furnace body 1, and its outer diameter is smaller than the inner diameter of the furnace body 1. This can prevent the flame from directly burning the inner wall of the furnace body 1 and reduce the maximum temperature of the outer wall of the furnace body 1, thereby reducing the risk of the furnace body 1 burning the human body to a certain extent. A fire-starting port corresponding to the second door hole 104 is opened on the left side of the lining 14. A smoke vent connected to the chimney pipe 5 is opened on the right side of the furnace body 1. A smoke exhaust hole corresponding to the smoke vent is opened on the right side of the lining 14. An ash hopper 6 extending into the furnace body 1 is inserted into the left side of the furnace body 1. The ash hopper 6 is located below the furnace bridge 4.

[0034] Specifically, an ignition mechanism is fixedly installed on the right side of the inner wall of the furnace body 1. The ignition assembly includes a hollow tube 7, a movable rod 8, an ignition lamp 9, and a positioning mechanism. The hollow tube 7 is fixedly installed on the right side of the inner wall of the furnace body 1, and it is located between the ash hopper 6 and the furnace bridge 4. The movable rod 8 is movably installed inside the hollow tube 7, with one end extending to the left side of the hollow tube 7. The ignition lamp 9 is fixedly installed on the top of the movable rod 8, and it is located on the left side of the hollow tube 7. The positioning mechanism is located on the left side of the movable rod 8, and it is used to limit the movable rod 8 to prevent it from rotating.

[0035] In addition, the positioning mechanism includes a sleeve 10, an inner rod 11, a limiting plate 12, and a docking rod 13. The sleeve 10 is fixedly disposed at the end of the movable rod 8 away from the hollow tube 7. The inner rod 11 is movably disposed inside the sleeve 10, with its two ends extending to the top and bottom of the sleeve 10, respectively. The limiting plate 12 is fixedly disposed at the top and bottom of the inner rod 11, which is used to prevent the inner rod 11 from detaching from the sleeve 10. The docking rod 13 is fixedly disposed at the end of the limiting plate 12 away from the inner rod 11, which is used to insert into the receiving seat 102 to prevent the movable rod 8 from rotating.

[0036] Please see Figure 4 The biomass pellets are directly filled into the furnace body 1 and placed on the furnace bridge 4. The first movable door 103 is opened, and the movable rod 8 is pulled out so that the ignition lamp 9 is partially outside the furnace body 1. Solid or liquid fuel is put into the furnace body 1. After ignition, the movable rod 8 and the ignition lamp 9 are reset. The flame of the fuel burning in the ignition lamp 9 ignites the biomass pellets through the furnace bridge 4. This ignition process does not require the user to pick up dry branches, further reducing the use of firewood. It is also easier to ignite than directly pouring liquid fuel onto the biomass pellets for ignition.

[0037] After ignition is complete, move the connecting rod 13 upward to disengage it from the receiving seat 102, and push the movable rod 8 back into the hollow tube 7. Due to gravity, the movable rod 8 will automatically rotate 180 degrees and flip to the bottom of the movable rod 8, without affecting the ash falling into the ash hopper 6 above. Alternatively, move the connecting rod 13 upward to disengage it from the receiving seat 102 and then rotate it 180 degrees to allow another connecting rod 13 to be inserted into the receiving seat 102.

[0038] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
