Description

Technical Field

[0001] This utility model relates to the field of combustion furnace technology, specifically a combustion furnace with automatic feeding function. Background Technology

[0002] As living standards continue to improve, most households have gradually transitioned from using ordinary coal stoves to environmentally friendly and less polluting appliances such as natural gas stoves and induction cookers. However, coal stoves are still widely used in rural areas and on the outskirts of cities. Coal is a non-renewable energy source, and relying solely on coal as fuel would not only easily lead to resource shortages, but also represent a significant expense for rural households.

[0003] A search revealed a renewable biomass fuel combustion stove disclosed in Chinese patent application number 201510017463.3. This patent includes: an outer cylinder with an air inlet and a top cover with a furnace opening; a combustion cylinder housed within the outer cylinder, forming an air chamber with closed upper and lower ends between the combustion cylinder and the outer cylinder; an air inlet on the combustion cylinder; and a combustion chamber inside the combustion cylinder, which communicates with the furnace opening. In use, renewable biomass fuel is placed into the combustion cylinder. Air enters the air chamber through the air inlet and then through the air inlet into the combustion chamber of the combustion cylinder to supply oxygen. The fuel is ignited from the furnace cover, burning from top to bottom, with the flame exiting from the furnace opening. Compared to existing stoves, this patent allows for easy movement and relocation, unaffected by location.

[0004] Although the aforementioned patent can be moved and relocated anytime and anywhere, unaffected by location, in actual use, it requires adding biomass briquettes little by little from the filling port, which is inconvenient for workers to operate the filling material and can easily burn their hands during operation. In addition, readily available combustible "waste" such as branches, leaves, dry grass, straw, and cow dung can also be used as fuel, completely replacing coal without incurring costs, and are considered renewable biomass fuels. However, this patent cannot pulverize these biomass fuels, resulting in limited contact area with air, which to some extent reduces combustion efficiency and may lead to incomplete combustion.

[0005] Therefore, a combustion furnace with automatic feeding function is needed to solve the above-mentioned problems. Utility Model Content

[0009] As a preferred embodiment of this utility model, the inner wall of the transition channel is fixedly connected to an arc-shaped plate, and one end of the arc-shaped plate is rotatably connected to the rotating shaft through a bearing.

[0010] As a preferred embodiment of this invention, the bottom of the feed inlet is inclined, and the transition channel is also inclined.

[0011] As a preferred embodiment of this utility model, a flue gas outlet is provided on one side of the combustion furnace, and a flue gas pipe is connected to the outside of the flue gas outlet. A protective frame is threadedly connected to the top of the flue gas pipe.

A servo motor 8 is fixedly connected to one side of the metering frame 7. The output end of the servo motor 8 passes through the metering frame 7 and is fixedly connected to... A metering roller 9 is connected to the furnace body 1. The surface of the metering roller 9 is provided with multiple metering grooves 10, which are arranged in a ring and uniformly. The top of the metering frame 7 is connected to a collection box 11, and the inner wall of the collection box 11 is arc-shaped. The top of the collection box 11 is connected to a feed hopper 12. A double roller crusher 13 is installed inside the collection box 11, and the two rollers of the double roller crusher 13 are located below the feed hopper 12. A discharge port is provided on one side of the furnace body 1, and a sealing door is hinged on one side of the discharge port to facilitate subsequent cleaning of the slag in the furnace body 1. A support frame is fixedly connected to the top of the combustion port of the furnace body 1.

[0023] refer to Figure 1 and Figure 2 A connection port is provided at the center of the bottom of the furnace body 1. A ventilation pipe 14 is fixedly connected to the bottom of the connection port. A ventilation hole 15 is provided on the surface of the ventilation pipe 14. A blower 16 is connected to the other end of the ventilation pipe 14.

[0024] As a technical optimization of this utility model, the arrangement of ventilation pipe 14, ventilation hole 15 and blower 16 can provide a large amount of air to fully mix with renewable biomass fuel, so that renewable biomass fuel can be fully burned in furnace body 1, thereby enhancing firepower and improving combustion efficiency, as well as reducing exhaust emissions, making the temperature distribution in furnace body 1 uniform and reducing fuel consumption.

[0025] refer to Figure 2 and Figure 3 An arc-shaped plate 17 is fixedly connected to the inner wall of the transition channel 3, and one end of the arc-shaped plate 17 is rotatably connected to the rotating shaft through a bearing.

[0026] As a technical optimization of this utility model, the arc plate 17 can be set to assist in supporting the rotating shaft, thereby making the spiral blade 6 more stable when rotating.

[0027] refer to Figure 2 The bottom of the feed inlet 2 is inclined, and the transition channel 3 is also inclined.

[0028] As a technical optimization of this utility model, by setting the bottom of the feed inlet 2 at an angle and the transition channel 3 at an angle, the crushed renewable biomass fuel can be guided so that it can slide stably into the interior of the furnace body 1.

[0029] refer to Figure 1 and Figure 2 A flue gas outlet is provided on one side of the combustion furnace, and a flue gas pipe 18 is connected to the outside of the flue gas outlet. A protective frame 19 is threadedly connected to the top of the flue gas pipe 18.

[0030] As a technical optimization of this utility model, the exhaust port, exhaust pipe 18 and protective frame 19 can remove the exhaust gas and smoke generated by combustion, ensure the safety and efficiency of the combustion process, and also realize the functions of ventilation and air exchange.

[0031] refer to Figure 1 and Figure 2 The four corners of the bottom of the furnace body 1 are fixedly connected with support columns, and the bottom of the transmission channel 4 is fixedly connected with a support frame, and the bottom of the support frame and the support columns are located on the same horizontal plane.

[0032] As a technical optimization of this utility model, the setting of support columns and support frames can stably support the furnace body 1 and the transmission channel 4, prevent the furnace body 1 from tilting or shaking, and ensure its safety and stability during use.

[0033] The working principle and usage process of this utility model are as follows: When using this combustion furnace, first place the furnace in the designated location, then connect the device to an external power source. Next, place a small amount of renewable biomass fuel in the furnace body 1 and ignite it. Then, add renewable biomass fuel to the feed hopper 12. At this point, the double-roller pulverizer 13 needs to be activated to pulverize and pre-treat the renewable biomass fuel, storing it in the collection box 11. Some of the renewable biomass fuel falls into the metering groove 10 of the metering roller 9 by gravity. Then, the servo motor 8 can be activated to drive the metering roller 9 to rotate, causing the metering groove 10 containing renewable biomass fuel located above to rotate downwards, allowing the renewable biomass fuel in the metering groove 10 to fall into the transmission channel 4, thereby pulverizing the renewable biomass fuel. The renewable biomass fuel is fed in a quantitative manner, with a certain gap between each feeding to further improve the safety of the feeding process. Then, the drive motor 5 drives the rotating shaft to rotate, and the spiral blades 6 transport the renewable biomass fuel, which enters the furnace body 1 through the transition channel 3 and the feed port 2 in sequence. This achieves automatic feeding of the furnace body 1 with high feeding safety. During the combustion of the renewable biomass fuel, the blower 16 can be started to allow the air cavity to enter the furnace body 1 through the ventilation holes 15 on the ventilation pipe 14, thereby increasing the air pressure and the amount of oxygen entering the combustion chamber, making the fuel burn more completely and reducing the generation of smoke. Finally, the exhaust port, exhaust pipe 18 and protective frame 19 are used to remove the exhaust gas and smoke generated by the combustion, ensuring the safety and efficiency of the combustion process.
