[0005] Existing biomass carbonization furnaces require the biochar produced during combustion to be removed, then materials to be loaded, and then carbonized again, resulting in low efficiency. Therefore, we propose an energy-saving continuous biomass carbonization furnace to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to solve the problem of low efficiency caused by the need to remove the biochar obtained from combustion, refill materials, and then perform combustion and carbonization again when using a biomass carbonization furnace. Therefore, an energy-saving continuous biomass carbonization furnace is proposed.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] An energy-saving biomass continuous carbonization furnace includes:
[0009] The base and the mounting bracket fixedly installed on the top of the base, the mounting bracket being provided with multiple combustion chambers;
[0010] Side panel, slidably mounted on one side of the mounting base;
[0011] The top cover is fixedly installed on one side of the side plate. The bottom of the top cover contacts the top of the mounting base. The top cover is used to cooperate with the side plate to close the two openings of the same combustion chamber.
[0012] Multiple push plates, each located in a different combustion chamber, are used to push the carbonized biochar out of the combustion chamber;
[0013] The actuation mechanism, located on the base, is used to move multiple push plates;
[0014] The moving mechanism, located on the mounting base, is used to move the side plate.
[0015] Preferably, the pushing mechanism includes multiple electric push rods fixedly installed on the top of the base, and a movable plate is fixedly installed on the output shaft of each of the multiple electric push rods.
[0016] Preferably, push rods are fixedly installed on one side of each of the multiple movable plates, and one end of each push rod is fixedly connected to the multiple push plates.
[0017] Preferably, sliding holes are provided on one side of the inner wall of each of the multiple combustion chambers, and the outer sides of the multiple push rods are slidably connected to the inner walls of the multiple sliding holes respectively.
[0018] Preferably, the moving mechanism includes a moving base, a moving groove is provided on one side of the mounting base, the moving base is slidably installed in the moving groove, and one side of the moving base is fixedly connected to the side plate.
[0019] Preferably, a screw is rotatably installed in the movable slot, the screw is threadedly connected to the movable seat, and a motor is fixedly installed on one side of the mounting seat.

[0021] Preferably, an air outlet pipe is fixedly connected to the top cover, and a conveying pipe is rotatably connected to the air outlet pipe.
[0022] Compared with the prior art, the advantages of this utility model are:
[0023] The biomass material to be carbonized is placed into multiple combustion chambers. The two openings of one combustion chamber are sealed by side plates and a top cover. Then, excess air is extracted from the combustion chamber by a vacuum device. The biomass material is then carbonized by an ignition device. The high-temperature gas generated by combustion is discharged from the delivery pipe. The high-temperature gas preheats the biomass material in the next combustion chamber, which is relatively energy-efficient. After carbonization in one combustion chamber is completed, the side plates and top cover are sealed to the two openings of the next combustion chamber, and the biomass in the next combustion chamber is directly carbonized. During the carbonization process, an electric push rod drives a moving plate to move towards the mounting base. The moving plate drives a push plate to move through the push rod. The push plate pushes the carbonized biomass material out of the combustion chamber, which can achieve continuous carbonization and improve efficiency.
[0024] This invention enables continuous carbonization, facilitates the ejection of carbonized biochar, improves efficiency, and allows for the utilization of waste heat from the discharged high-temperature gas, resulting in energy savings. Attached Figure Description

[0031] Reference Figures 1-4 An energy-saving biomass continuous carbonization furnace, comprising:
[0032] The base 1 and the mounting seat 2 fixedly installed on the top of the base 1, the mounting seat 2 being provided with multiple combustion chambers 3;
[0033] Side plate 4 is slidably mounted on one side of mounting base 2;
[0034] The top cover 5 is fixedly installed on one side of the side plate 4. The bottom of the top cover 5 contacts the top of the mounting base 2. The top cover 5 is used to cooperate with the side plate 4 to close the two openings of the same combustion chamber 3.
[0035] Multiple push plates 8 are respectively installed in multiple combustion chambers 3 to push the carbonized biochar out of the combustion chambers 3;
[0036] The driving mechanism, located on the base 1, is used to move multiple push plates 8;
[0037] The moving mechanism, located on the mounting base 2, is used to move the side plate 4.
[0038] In this embodiment, the pushing mechanism includes multiple electric push rods 11 fixedly installed on the top of the base 1, and a movable plate 10 is fixedly installed on the output shaft of each of the multiple electric push rods 11.
[0039] In this embodiment, push rods 9 are fixedly installed on one side of each of the multiple movable plates 10, and one end of each push rod 9 is fixedly connected to a multiple push plate 8.
[0040] In this embodiment, sliding holes are provided on one side of the inner wall of each of the multiple combustion chambers 3, and the outer sides of the multiple push rods 9 are slidably connected to the inner walls of the multiple sliding holes respectively.
[0041] In this embodiment, the moving mechanism includes a moving seat 13. A moving groove 12 is provided on one side of the mounting seat 2. The moving seat 13 is slidably installed in the moving groove 12. One side of the moving seat 13 is fixedly connected to the side plate 4.
[0042] In this embodiment, a screw 14 is rotatably installed in the movable groove 12. The screw 14 is threadedly connected to the movable seat 13. A motor 15 is fixedly installed on one side of the mounting seat 2. The output shaft of the motor 15 extends into the movable groove 12 and is fixedly connected to one end of the screw 14.
[0043] In this embodiment, an ignition device 16 and a vacuum device 17 are connected to the side plate 4.
[0044] In this embodiment, an air outlet pipe 6 is fixedly connected to the top cover 5, and a conveying pipe 7 is rotatably connected to the air outlet pipe 6.
[0045] In this embodiment, during use, the biomass material to be carbonized is placed into multiple combustion chambers 3. The motor 15 drives the screw 14 to rotate, causing the movable seat 13, threadedly connected to the screw 14, to move laterally. The movable seat 13 moves the side plate 4, which in turn moves the top cover 5. The side plate 4 and top cover 5 seal the two openings of one combustion chamber 3.

The high-temperature gas generated by combustion is discharged from the conveying pipe 7, and the high-temperature gas is used for the next combustion chamber. The biomass material in chamber 3 is preheated, which is more energy-efficient. After carbonization in one combustion chamber 3 is completed, the screw 14 is rotated by the motor 15, so that the side plate 4 and the top cover 5 close the two openings of the next combustion chamber 3, and the biomass in the next combustion chamber 3 is directly carbonized.

The push plate 8 pushes the carbonized biomass material out of the combustion chamber 3. Through the above operation, continuous carbonization can be achieved and efficiency can be improved. Example 2
[0046] The difference from Embodiment 1 is that a locking bolt is threaded on the air outlet pipe 6, which locks the delivery pipe 7, making the delivery pipe 7 less flexible. It can rotate, but it will not rotate arbitrarily.
