Description

Technical Field

[0001] This utility model relates to the field of carbonization furnace technology, specifically a mobile skid-mounted biomass carbonization furnace. Background Technology

[0002] Skid-mounted biomass refers to a modular and integrated design of biomass energy processing equipment, enabling rapid deployment and operation in a "plug-and-play" manner. Mobile biomass pyrolysis units can produce products such as bio-oil and biochar. Currently, there are three types of carbonization furnaces: ordinary type (can only be used to produce charcoal and cannot collect fuel gas); wood carbonization equipment (used to carbonize branches, wood blocks, coconut shell blocks, scraps from furniture factories, etc. This equipment can be equipped with a gasification furnace to recover gas and turn it into fuel gas for the carbonization furnace's own use or other purposes); and charcoal powder production line (machines used to produce charcoal powder, which can carbonize agricultural stalks such as rice husks, sawdust, bamboo powder, and sugarcane stalks into charcoal powder, which can be processed into activated carbon).

[0003] A mobile environmentally friendly carbonization furnace is disclosed in Chinese utility model patent CN222119133U. Although the carbonization furnace has the environmental protection ability to adsorb the generated smoke and dust, it still has the following defects: First, the slag in the combustion chamber is not easy to be discharged. When adding fuel, the slag will affect the combustion of the fuel. Second, soot will accumulate on the inner wall of the exhaust pipe. When there is too much soot, it will block the exhaust pipe and affect the exhaust efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Please see Figures 1 to 3This utility model provides a technical solution for a mobile skid-mounted biomass carbonization furnace, comprising a furnace body 1. The furnace body 1 is equipped with a carbonization chamber 101 and a combustion chamber 102. A sealing door 2 is provided on the outer side of the carbonization chamber 101 and is installed on the outer wall of the furnace body 1. A flue pipe 19 is provided at the top of the combustion chamber 102. A pipe cleaning mechanism is provided on the outer wall of the furnace body 1. The combustion chamber 102 is located directly below the carbonization chamber 101. The inner bottom wall of the combustion chamber 102 is inclined. A filling port 8 is provided on the end face of the combustion chamber 102. A slag discharge port 11 is provided on the side of the combustion chamber 102. A slag discharge mechanism is provided inside the combustion chamber 102. Bottom support legs 30 are installed at the bottom, and casters 31 are installed below the bottom support legs 30. One side of the sealing door 2 is hinged to the outer wall of the furnace body 1. A bearing seat 5 is installed on the sealing door 2, and a threaded rod 4 is rotatably connected to the bearing seat 5. A fixing block 3 is installed on the outer wall of the furnace body 1. The end of the threaded rod 4 is threaded to the fixing block 3. A handwheel 6 is installed on the tail of the threaded rod 4. A handle 7 is installed on the sealing door 2. A rotating support plate 9 is installed below the outer side of the filling port 8. The rotating support plate 9 is rotatably connected to the outer wall of the combustion chamber 102. A rotating locking block 10 is fixedly connected to the outer wall of the combustion chamber 102. The rotating locking block 10 and the rotating support plate 9 are locked together.

[0025] The pipe cleaning mechanism consists of a second support 20, a fixed sleeve 21, a hydraulic rod 22, a movable frame 23, a second motor 27, a transmission pulley set 28, and a cleaning brush 29. The second support 20 is fixedly installed on the outer wall of the furnace body 1. The fixed sleeve 21 is installed on the top of the second support 20. The hydraulic rod 22 is installed inside the fixed sleeve 21. The movable frame 23 is sleeved inside the fixed sleeve 21. The movable end of the hydraulic rod 22 is rotatably connected to the bottom of the movable frame 23. The fixed end of the hydraulic rod 22 is fixedly connected to the inner bottom wall of the fixed sleeve 21.

[0026] The outer wall of the fixed sleeve 21 is provided with a side slide groove 24 and a top slide groove 26. There are two sets of side slide grooves 24, which are symmetrically distributed on the outer wall of the fixed sleeve 21. The top slide groove 26 is connected to the two sets of side slide grooves 24. A limit block 25 is fixedly connected to the outer wall of the movable frame 23. The limit block 25 slides inside the side slide groove 24. A rotating handle is provided at the end of the limit block 25.

[0027] The second motor 27 is mounted on the top of the movable frame 23, and the transmission pulley group 28 is located on the top of the movable frame 23. The output end of the second motor 27 is connected to the input end of the transmission pulley group 28, and the output end of the transmission pulley group 28 is connected to the end of the cleaning brush 29. The diameter of the cleaning brush 29 is the same as the inner diameter of the exhaust pipe 19.

[0028] In use, open the sealing door 2, then place the skid-mounted biomass to be carbonized into the carbonization chamber 101, and then close the sealing door 2. Next, turn multiple handwheels 6 to turn the end of the threaded rod 4 into the fixing block 3. During the turning of the end of the threaded rod 4, the sealing door 2 and the carbonization chamber 101 are sealed to prevent external air from entering. Then, put fuel into the combustion chamber 102 and ignite the fuel to heat the carbonization chamber 101 and carbonize the skid-mounted biomass inside the carbonization chamber 101. The smoke generated during carbonization inside the carbonization chamber 101 will be discharged through the exhaust pipe 19. After long-term use, soot will stick to the inner wall of the exhaust pipe 19. If the soot is not cleaned for a long time, it will block the pipe. When the temperature is high, the soot will burn, affecting the use of the carbonization furnace. Therefore, after a period of time, the exhaust pipe 19 needs to be opened and the exhaust pipe 19 needs to be cleaned by starting the pipe cleaning mechanism.

[0029] When cleaning the exhaust pipe 19, first activate the hydraulic rod 22 to move the moving frame 23 upward, so that the limiting block 25 on the outside of the moving frame 23 moves inside the side slide groove 24 of the fixed sleeve 21. After the limiting block 25 moves along the side slide groove 24 to the top slide groove 26, the entire moving frame 23 can be manually rotated by the rotating handle on the limiting block 25, so that the moving frame 23 rotates 180 degrees. At this time, the cleaning brush 29 is located directly above the exhaust pipe 19. Then, activate the second motor 27 and the hydraulic rod 22, so that the cleaning brush 29 rotates and moves downward at the same time, cleaning the inner wall of the exhaust pipe 19 located directly below the cleaning brush 29, so that the soot inside the exhaust pipe 19 falls off, thereby reducing the accumulation of soot on the inner wall of the exhaust pipe 19, improving exhaust efficiency and preventing the problem of soot combustion.

[0030] Example 2

[0031] Please see Figure 2 , Figure 4 and Figure 5 The present invention provides a technical solution in which the slag discharge mechanism is composed of a first support 12, a first motor 13, a transmission screw 14, a fixed seat 15, a slider 16 and a push plate 18. A through groove 17 is provided on the outer wall of the combustion chamber 102. The through groove 17 is inclined and the inclination angle is consistent with the inclination angle of the inner bottom wall of the combustion chamber 102. The slider 16 slides inside the through groove 17. The end of the slider 16 is fixedly connected to the push plate 18. The push plate 18 is set inside the combustion chamber 102 and the bottom of the push plate 18 abuts against the inner bottom wall of the combustion chamber 102.

[0032] The first bracket 12 is fixedly installed on the outer wall of the furnace body 1. The first motor 13 is installed on the first bracket 12. The output end of the first motor 13 is connected to the transmission screw 14. The slider 16 is threadedly connected to the transmission screw 14. The fixed seat 15 is installed on the outer wall of the combustion chamber 102. The two ends of the transmission screw 14 are rotatably connected to the fixed seat 15.

[0033] During use, because residue is generated inside the combustion chamber 102 after the fuel is burned, and the residue is not easy to clean in time when the temperature is high, it will affect the subsequent addition of fuel and the combustion effect. Therefore, it is necessary to start the first motor 13 periodically. The first motor 13 drives the transmission screw 14 to rotate, so that the slider 16 on the transmission screw 14 slides along the through groove 17, and the push plate 18 at the end of the slider 16 moves. During the movement of the push plate 18, the residue inside the combustion chamber 102 moves towards the slag discharge port 11, so as to achieve the effect of rapid slag discharge and facilitate the subsequent addition of fuel.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
