[0001] This utility model relates to the field of combustion furnace technology, and in particular to an environmentally friendly and multifunctional combustion furnace. Background Technology
[0002] The furnace is a three-dimensional space enclosed by furnace walls for fuel combustion. The furnace's function is to ensure the fuel burns as completely as possible and to cool the flue gas temperature at the furnace outlet to a level permissible for safe operation of the convective heating surfaces. Therefore, the furnace should have sufficient volume and be able to accommodate a sufficient number of heating surfaces. Furthermore, the furnace should have a suitable shape and size to facilitate coordination with the burners, organize the aerodynamic field within the furnace, prevent the flame from adhering to or impinging on the walls, ensure high flame density, and maintain uniform heat load on the walls.
[0003] During combustion, the furnace produces a lot of smoke and dust. The flue gas is directly discharged to the outside, which will cause certain environmental pollution. At the same time, during the use of the furnace, especially in winter, the outside temperature is low. When the low temperature enters the furnace, it will affect the internal combustion calorific value. Therefore, an environmentally friendly and multifunctional combustion furnace is proposed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Refer to Figure 1-4 An environmentally friendly multifunctional combustion furnace includes a furnace body 1, a protective door 2 on one side of the furnace body 1, and an exhaust pipe 3 on the top of the furnace body 1. The exhaust pipe 3 has an L-shaped structure and a filter screen 4 is installed on the exhaust pipe 3. During combustion, the internal combustion of the furnace body 1 will generate smoke and dust, which will be discharged from the exhaust pipe 3. The filter screen 4 on the exhaust pipe 3 can effectively block and filter smoke and dust. The exhaust pipe 3 is generally long, and the filter screen 4 is located at the end of the exhaust pipe 3. When the flue gas is discharged, the temperature is relatively low and will not affect the filter screen 4. An ash cleaning component is installed on the exhaust pipe 3. An air inlet component is connected to the outside of the exhaust pipe 3, and an air supply component is connected to the furnace body 1. The air supply component is connected to the air inlet component.
[0022] Specifically, the air supply assembly includes an exhaust fan 15 installed on the side of the furnace body 1. An air inlet pipe 16 is connected between the exhaust fan 15 and the air inlet pipe 13. An air outlet pipe 17 is connected to one side of the exhaust fan 15. The air outlet pipe 17 is arranged in a U-shape. Three air supply pipes 18 are connected to one side of the air outlet pipe 17. The three air supply pipes 18 are located on three sides of the furnace body 1. Control valves 19 are installed on the air supply pipes 18. During use, the furnace body 1 needs to be supplied with oxygen in a timely manner. When the exhaust fan 15 on the air supply assembly is running, it sends external air into the air outlet pipe 17 and finally into the furnace body 1 from the multiple air supply pipes 18. The three air supply pipes 18 are respectively located in three directions of the furnace body 1, which can achieve uniform air supply and ensure effective combustion inside the furnace body 1.
[0023] Specifically, the air intake assembly includes an air intake pipe 13 installed on the top of the furnace body 1, an exhaust pipe 3 located inside the air intake pipe 13, an air intake hopper 14 connected to the top of the air intake pipe 13, and the air intake pipe 13 surrounding the outside of the exhaust pipe 3. The air drawn by the exhaust fan 15 enters between the exhaust pipe 3 and the air intake pipe 13. The outside of the exhaust pipe 3 has a higher temperature, so the incoming air will be heated to achieve the effect of heat recovery and utilization. The heated air enters the furnace body 1 to avoid the combustion inside the furnace body 1 being affected by the low temperature of the incoming air.
[0024] Specifically, the dust removal assembly includes an operating hole 5 on the exhaust pipe 3, a downward plate 7 movably mounted on the operating hole 5, a scraper 8 fixedly mounted on one side of the downward plate 7, the scraper 8 contacting one side of the filter screen plate 4, a side dust collection hole 6 on the inner wall of the operating hole 5, the bottom of the downward plate 7 extending outside the operating hole 5 and connected to a bottom sealing plate 10, a smoke exhaust hole 9 on one side of the downward plate 7 located on one side of the filter screen plate 4, a fixing block 11 fixedly mounted on the top of the exhaust pipe 3, and a connecting bolt 12 on the fixing block 11. Bolt 12 is threaded onto the lower moving plate 7. After prolonged filtration, a significant amount of dust accumulates on the surface of the filter screen 4. At this point, the operator loosens the connecting bolt 12 on the dust collection cleaning assembly, allowing the lower moving plate 7 to move downwards. As the lower moving plate 7 moves, it drives the scraper 8 to move as well. After the scraper 8 moves downwards, it can scrape away the dust on the surface of the filter screen 4. The scraped dust will fall from the side dust collection hole 6 and onto the bottom sealing plate 10 below, where the operator can clean it promptly. The dust on the surface of the filter screen 4 can be cleaned simply by moving it downwards, making cleaning quite convenient.
[0025] During use: The smoke and dust generated during combustion in the furnace body 1 will be discharged from the exhaust pipe 3. The filter screen 4 effectively blocks the dust in the smoke. After prolonged filtration, a significant amount of dust accumulates on the surface of the filter screen 4. The operator moves the lowering plate 7 downwards, and the scraper 8 moves to scrape off the dust from the surface of the filter screen 4. The scraped dust will fall from the side ash collection hole 6. Cleaning the surface of the filter screen 4 is convenient by moving it downwards. The exhaust fan 15 operates to send external air into the exhaust pipe 17, and finally into the furnace body 1 through multiple air supply pipes 18, achieving uniform air supply and ensuring effective combustion inside the furnace body 1. The air inlet pipe 13 surrounds the exhaust pipe 3, heating the incoming air and achieving heat recovery. The heated air enters the furnace body 1, preventing the low temperature of the incoming air from affecting combustion inside the furnace body 1. This makes the process convenient.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
