Description

Technical Field

[0001] This utility model belongs to the field of waste treatment technology, specifically a carbonization furnace for producing biochar. Background Technology

[0002] Biochar is an excellent soil conditioner that can increase soil organic matter content, improve soil moisture retention, aeration, and nutrient storage capacity. It can help improve soil pH, enhance plant growth, and increase crop yield. The carbonization furnace can provide a precise temperature-controlled environment, allowing raw materials to pyrolyze at the appropriate temperature. By strictly controlling temperature and oxygen supply, the quality and yield of biochar can be optimized.

[0003] The principle of a carbonization furnace for producing biochar mainly involves two aspects: pyrolysis and carbonization reaction. By applying precise carbonization reaction and pyrolysis principles, the carbonization furnace for producing biochar can efficiently carbonize waste materials that need to be carbonized, providing strong support for waste carbonization.

[0004] Existing charcoal furnaces often remove the carbonized biochar directly from the discharge port after carbonization. Since the biochar retains a certain temperature when removed, it can spontaneously combust when it comes into contact with air, ultimately leading to resource waste or even fire. Therefore, a carbonization furnace for producing biochar is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, conventional charcoal furnaces often remove the carbonized biochar directly from the discharge port after carbonization. Since the biochar retains a certain temperature when removed, it can spontaneously combust when it comes into contact with air, ultimately leading to resource waste or even fires. This invention proposes a carbonization furnace for producing biochar.

[0006] The technical solution adopted by this utility model to solve its technical problem is a carbonization furnace for producing biochar, including a carbonization furnace body, a top cover installed on the top of the carbonization furnace body, a feed inlet on the top of the top cover, support legs fixedly installed at all four ends of the bottom of the carbonization furnace body, a flue pipe fixedly installed on one side of the outer side of the carbonization furnace body, a burner fixedly installed on the other side of the outer side of the carbonization furnace body, the output end of the burner located inside the carbonization furnace body, a filter box installed on the outer side of the end of the flue pipe away from the carbonization furnace body, an electric valve installed at the center of the bottom of the carbonization furnace body, a cooling box installed on the outer side of one end of the electric valve, a cooling plate fixedly installed on the inner wall of the cooling box, the cooling plate being a U-shaped plate, cooling pipes opening inside the cooling plate, the cooling pipes being interconnected, and one end of the cooling pipes being fixedly installed on the outer side. A first infusion pipe is fixedly installed, and a second infusion pipe is fixedly installed on the other end of the cooling pipe. A storage tank is located on the outside of the end of the first infusion pipe away from the cooling box, and a water pump is installed on the outside of the end of the second infusion pipe away from the cooling box. The input end of the water pump is fixedly installed inside the storage tank, and a semiconductor refrigeration plate is fixedly installed on the outer side of the storage tank. The water pump delivers the coolant inside the cooling box to the cooling plate to cool the high-temperature biochar inside the cooling box. When the temperature of the coolant rises due to prolonged use, the water pump continues to draw the coolant from the cooling box into the cooling plate. At this time, the excessively hot coolant will flow back into the cooling box along the cooling pipe to continue cooling, achieving a recycling effect. Cooling the high-temperature biochar can prevent spontaneous combustion when it comes into contact with air, thereby reducing safety hazards and biochar loss.

[0007] Preferably, the filter box is provided with multiple filter plates inside, and each of the multiple filter plates has a handle fixedly installed on one side of its outer side. An exhaust pipe is fixedly installed on the top of the filter box. Each of the multiple filter plates has an activated carbon layer inside. The multiple filter plates can filter impurities from the emitted flue gas through the activated carbon layer inside, so as to prevent air pollution when it is discharged.

[0008] Preferably, the bottom end of the top cover has an installation groove, and sealing gaskets are fixedly installed on both sides of the inner wall of the installation groove. The multiple sealing gaskets are made of rubber. One end of the carbonization furnace body is tightly attached to the outside of the multiple sealing gaskets. The rubber sealing gaskets can increase the friction and adhesion between their outer surface and the outer surface of the carbonization furnace body, thereby improving the sealing effect between the top cover and the carbonization furnace body.

[0009] Preferably, each of the multiple filter plates has a connection port at both ends inside, and a limit rod is slidably installed at both ends inside the filter box. One end of the limit rod passes through the inside of the multiple filter plates and is slidably installed at the bottom of the inner wall of the filter box. The limit rod controls the multiple filter plates, making them more stable during use and allowing for easier removal and replacement of the multiple filter plates.

[0010] Preferably, the burner, electric valve, water pump, and semiconductor cooling plate are all electrically connected to an external control panel. By connecting the burner, electric valve, water pump, and semiconductor cooling plate to the control panel, operators can more conveniently control the main body of the carbonization furnace.

[0011] Preferably, the bottom of the cooling box is equipped with a door, which can be opened to remove the cooled biochar when it is necessary to take it out.

[0012] The advantages of this utility model are:

[0013] This invention addresses the problem of waste carbonization in traditional charcoal furnaces. During waste treatment, a water pump delivers coolant from a cooling tank to a cooling plate to cool the high-temperature biochar inside. When the coolant temperature rises due to prolonged use, the pump draws more coolant from the tank back into the cooling plate. Excessively hot coolant then flows back into the tank through cooling pipes for further cooling, achieving a cyclical cooling effect. This solves the problem of existing charcoal furnaces where biochar is directly removed from the outlet after carbonization. Since the biochar retains a certain temperature upon removal, it can spontaneously combust upon contact with air, leading to resource waste and even fires. Cooling the high-temperature biochar prevents spontaneous combustion upon contact with air, reducing safety hazards and biochar loss. Attached Figure Description

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a carbonization furnace for producing biochar includes a furnace body 1. A top cover 2 is installed on the top of the furnace body 1, and a feed inlet 3 is opened on the top of the top cover 2. Support legs 4 are fixedly installed at all four ends of the bottom of the furnace body 1. A flue pipe 6 is fixedly installed on one side of the furnace body 1, and a burner 5 is fixedly installed on the other side of the furnace body 1. The output end of the burner 5 is located inside the furnace body 1. A filter box 19 is installed on the outside of the end of the flue pipe 6 furthest from the furnace body 1. An electric valve 7 is installed at the center of the bottom of the furnace body 1, and a cooling box 8 is installed on the outside of one end of the electric valve 7. A cooling plate 9, U-shaped, is fixedly installed on the inner wall of the cooling box 8. Cooling pipes 10 are interconnected within the cooling plate 9. A first infusion pipe 11 is fixedly installed at one end of each cooling pipe 10, and a second infusion pipe 12 is fixedly installed at the other end. A storage tank 14 is located at the end of the first infusion pipe 11 furthest from the cooling box 8. A water pump 13 is installed at the end of the second infusion pipe 12 furthest from the cooling box 8. The input end of the water pump 13 is fixedly installed inside the storage tank 14. A semiconductor cooling plate 15 is fixedly installed on the outer side of the storage tank 14. During operation, the existing carbonization furnace... When removing the carbonized biochar, there is a risk of spontaneous combustion upon contact with air, leading to resource waste and even fire. To ensure safer biochar removal, this device places the waste to be carbonized into the carbonization furnace body 1 through the feed inlet 3. The burner 5 then supplies high-temperature gas to the furnace body 1 for carbonization. The resulting flue gas flows out through the exhaust pipe 6. A filter box 19 is located at one end of the exhaust pipe 6. Multiple activated carbon filter plates 20 inside the filter box 19 filter the combustion flue gas, reducing air pollution during emission. After carbonization is complete, the flue gas is then... An external control panel opens the connected electric valve 7. Once the electric valve 7 is open, the carbonized waste enters the cooling tank 8. At this time, the semiconductor cooling plate 15 cools the coolant in the storage tank 14. After cooling is complete, the water pump 13 is activated to transport the cooled coolant to the cooling plate 9. The coolant in the cooling plate 9 cools the carbonized waste inside the cooling tank 8. When the coolant temperature rises after prolonged use, the water pump 13 continues to transport the cooled coolant from the cooling tank 8 to the cooling plate 9. The cooled coolant that has risen in temperature will flow back into the cooling tank 8 through the cooling pipe 10 for further cooling.

[0023] The filter box 19 is equipped with multiple filter plates 20 inside, and each of the filter plates 20 has a handle 21 fixedly installed on one side of its exterior. An exhaust pipe 24 is fixedly installed on the top of the filter box 19. During operation, existing carbonization furnaces may cause spontaneous combustion of the carbonized biochar when it comes into contact with air, leading to resource waste or even fire. To make the removal of biochar safer, this device uses multiple activated carbon filter plates 20 inside the filter box 19 to filter the flue gas produced by combustion, reducing air pollution during emission.

[0024] The bottom end of the top cover 2 has an installation groove 17. Both sides of the inner wall of the installation groove 17 are fixedly installed with sealing gaskets 18. The sealing gaskets 18 are all made of rubber. One end of the carbonization furnace body 1 is tightly attached to the outside of the sealing gaskets 18. During operation, when the carbonized biochar is taken out of the existing carbonization furnace, it will spontaneously combust when it comes into contact with air, resulting in resource waste and even fire. In order to make the removal of biochar safer, the sealing gaskets 18 can increase the sealing of the connection between the top cover 2 and the carbonization furnace body 1.

[0025] Each of the multiple filter plates 20 has a connection port 22 at both ends inside, and each of the filter box 19 has a limiting rod 23 slidably installed at both ends inside. One end of the limiting rod 23 passes through the interior of the multiple filter plates 20 and is slidably installed at the bottom of the inner wall of the filter box 19. During operation, existing carbonization furnaces may cause spontaneous combustion when the carbonized biochar is removed, leading to resource waste or even fire. To make the removal of biochar safer, this device uses the limiting rod 23 to limit and fix the multiple filter plates 20, preventing them from falling off during use.

[0026] The burner 5, electric valve 7, water pump 13, and semiconductor cooling plate 15 are all electrically connected to an external control panel. During operation, existing carbonization furnaces may cause spontaneous combustion when the carbonized biochar comes into contact with air, leading to resource waste or even fire. To make the removal of biochar safer, this device can more efficiently and conveniently control the main body of the carbonization furnace 1 by connecting to an external control panel.

[0027] The bottom of the cooling box 8 is equipped with a door 16. During operation, when the existing carbonization furnace removes the carbonized biochar, the removed biochar may spontaneously combust when it comes into contact with air, leading to resource waste or even fire. In order to make the removal of biochar safer, this device allows the cooled biochar to be removed through the door 16 installed at the bottom of the cooling box 8.

[0028] Working principle: When carbonizing waste using a carbonization furnace during waste treatment, the waste to be carbonized is first placed into the main body 1 of the carbonization furnace through the feed inlet 3. Then, the burner 5 is started to supply high-temperature gas to the main body 1 of the carbonization furnace for carbonization. The flue gas generated during the carbonization process flows out through the exhaust pipe 6. A filter box 19 is installed on the outside of one end of the exhaust pipe 6. Multiple activated carbon filter plates 20 installed inside the filter box 19 can filter the flue gas generated by combustion, reducing air pollution during emission. After carbonization is completed, the external control panel drives the connected electric... When the electric valve 7 is opened, the carbonized waste will enter the cooling tank 8. At this time, the coolant in the storage tank 14 is cooled by the semiconductor cooling plate 15. After cooling is completed, the water pump 13 is started to transport the cooled coolant to the cooling plate 9. The coolant in the cooling plate 9 cools the carbonized waste in the cooling tank 8. When the temperature of the coolant rises after long-term use, the water pump 13 will continue to transport the cooled coolant in the cooling tank 8 to the cooling plate 9. The cooled coolant that has risen in temperature will flow back into the cooling tank 8 through the cooling pipe 10 to continue cooling.
