[0008] The above technical solution uses two bolts located at the front and rear ends of the top of the combustion cylinder. These bolts cooperate with the through grooves on the cylinder cover to fix the cylinder cover to the top of the combustion cylinder, ensuring the airtightness of the equipment during combustion and preventing gas leakage and heat loss.

[0009] As a further improvement to the above solution, the lifting device includes a lifting frame, a drive motor is fixedly connected to the top of the lifting frame, a lead screw is fixedly connected to the output end of the drive motor, a sliding block is threaded onto the surface of the lead screw, a connecting rod is fixedly connected to the top of the sliding block, and a placement plate is fixedly connected to the bottom of the connecting rod.

[0010] With the above technical solution, the connecting rod is U-shaped, and the combustion cylinder is inside the connecting rod.

[0011] As a further improvement to the above solution, the lifting frame is located on the left and right sides of the base, one side of the lifting frame is fixedly connected to one side of the base, a groove is provided on one side of the lifting frame, the surface of the lead screw is rotatably connected to the inside of the lifting frame, the surface of the sliding block is slidably connected to the inner wall of one side of the lifting frame, and the placement plate is located on the top of the support rod.

[0012] As a further improvement to the above solution, the fixing device includes a bucket lid, the top of which is fixedly connected to a handle.

[0013] As a further improvement to the above solution, the bottom of the bucket lid is provided with a groove, and the top of the bucket lid is provided with through grooves at the front and back.

[0014] As a further improvement to the above solution, the barrel cover is located at the top of the combustion cylinder, the bottom groove of the barrel cover is inserted into the top of the connecting rod, and the top through groove of the barrel cover is slidably connected to the surface of the bolt.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a placement plate. By activating the drive motor at the top of the lifting frame, the lead screw rotates, causing the sliding block to slide along the groove of the lifting frame. This allows the placement plate at the bottom of the connecting rod to descend to the top of the support rod inside the combustion chamber, thus achieving automatic lifting and lowering of the placement plate. This simplifies the raw material loading and unloading process and improves production efficiency.

[0016] This invention utilizes a flue gas recovery pipe to introduce the high-temperature flue gas generated during combustion into a waste heat recovery system, thereby achieving heat recycling and significantly reducing energy consumption. Attached Figure Description

The high-temperature flue gas generated during combustion is discharged through the flue gas recovery pipe 10 at the rear end of the combustion cylinder 3 and enters the waste heat recovery system for heat reuse. Once the bone charcoal has been burned, loosen the nut, and drive motor 502 will reverse to raise the placement plate 506, allowing the finished product to be easily removed.

[0021] The bottom of the combustion cylinder 3 has a through groove, and there are two bolts 6, which are located at the front and rear ends of the top of the combustion cylinder 3 respectively.

[0022] The lifting device 5 includes a lifting frame 501. A drive motor 502 is fixedly connected to the top of the lifting frame 501. A lead screw 503 is fixedly connected to the output end of the drive motor 502. A sliding block 504 is threaded onto the surface of the lead screw 503. A connecting rod 505 is fixedly connected to the top of the sliding block 504. A placement plate 506 is fixedly connected to the bottom of the connecting rod 505. The raw material to be burned is placed on the placement plate 506 supported by the U-shaped connecting rod 505. The drive motor 502 at the top of the lifting frame 501 is started. The lead screw 503 rotates and drives the sliding block 504 to slide along the groove of the lifting frame 501, so that the placement plate 506 descends to the top of the support rod 4 inside the combustion cylinder 3.

[0023] The lifting frame 501 is located on the left and right sides of the base 1. One side of the lifting frame 501 is fixedly connected to one side of the base 1. A groove is provided on one side of the lifting frame 501. The surface of the lead screw 503 is rotatably connected to the inside of the lifting frame 501. The surface of the sliding block 504 is slidably connected to the inner wall of one side of the lifting frame 501. The placement plate 506 is located on the top of the support rod 4.

[0024] The fixing device 7 includes a barrel cover 701, and a handle 702 is fixedly connected to the top of the barrel cover 701. The bottom groove of the barrel cover 701 is precisely inserted into the top of the connecting rod 505.

[0025] The bottom of the bucket lid 701 has a groove, and the top of the bucket lid 701 has through grooves at the front and back.

[0026] The barrel cover 701 is located at the top of the combustion cylinder 3. The bottom groove of the barrel cover 701 is inserted into the top of the connecting rod 505, and the top through groove of the barrel cover 701 is slidably connected to the surface of the bolt 6.

[0027] The implementation principle of an energy-saving bone charcoal stove with waste heat recovery in this embodiment is as follows: First, the raw material to be burned is placed on the placement plate 506 supported by the U-shaped connecting rod 505. The drive motor 502 at the top of the lifting frame 501 is started, and the lead screw 503 rotates, causing the sliding block 504 to slide along the groove of the lifting frame 501, so that the placement plate 506 at the bottom of the connecting rod 505 at the top of the sliding block 504 descends to the top of the support rod 4 inside the combustion cylinder 3. Then, the bottom groove of the barrel cover 701 is precisely inserted into the top of the connecting rod 505. The bolts 6 at the front and rear ends of the top of the combustion cylinder 3 pass through the through groove at the top of the barrel cover 701, and then are tightened with nuts to achieve a seal in the combustion cylinder 3. Next, the gas from the gas device 2 enters from the through groove at the bottom of the combustion cylinder 3, and the outside air enters through the ventilation pipe at the bottom of the surface of the combustion cylinder 3. After mixing with the gas, it burns inside the cylinder, releasing heat to burn the raw material. The high-temperature flue gas generated during the combustion process is discharged through the flue gas recovery pipe 10 at the rear end of the combustion cylinder 3 and enters the waste heat recovery system to reuse the heat. Once the bone charcoal has been burned, loosen the nut, and drive motor 502 will reverse to raise the placement plate 506, allowing the finished product to be easily removed.
