Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically an automatic feeding device for a biomass gasification furnace. Background Technology

[0002] A biomass gasification furnace is a device that converts biomass (such as wood, straw, furfural, and other organic waste) into combustible gas (syngas, mainly composed of CO, H2, CH4, etc.) through a thermochemical conversion process. This technology not only enables the resource utilization of waste but also provides clean energy, making it suitable for power generation, heating, or chemical raw material production.

[0003] Existing biomass gasification furnaces typically use screw feeders to continuously transport materials to the furnace opening at a high position. However, when the material enters the fuel bin, it only falls along the same position and cannot be evenly distributed inside the fuel bin, reducing the utilization rate of the fuel bin space. Furthermore, the uneven distribution of materials affects the efficiency of subsequent processing. Utility Model Content

The second equalization mechanism consists of an equalization tube, a distribution net installed on the inner wall of the equalization tube, and a rotating shaft rotatably connected to the distribution net. The equalization tube is connected to the discharge end of the feeding mechanism. The rotating shaft is driven to rotate by a drive component installed on the equalization tube. An installation rod is installed on the rotating shaft. Multiple sets of dispersing plates are installed at the top of the installation rod, and multiple sets of agitating brushes are installed at the bottom of the installation rod. The agitating brushes are in contact with the distribution net.

[0009] Preferably, the driving component includes a rotating rod that is driven to rotate by a motor mounted on the feeding tube; a protective box that is mounted on the inner wall of the feeding tube, the rotating rod being rotatably connected to the protective box, and a rotating shaft being rotatably connected to the protective box; and a transmission assembly that is disposed in the inner cavity of the protective box, the transmission assembly consisting of two sets of meshing bevel gears, the two sets of bevel gears being respectively mounted on the rotating shaft and the rotating rod.

[0017] Example 1, as Figures 1 to 3 As shown, the present invention proposes an automatic feeding device for a biomass gasification furnace, comprising a buffer tank 1, a first equalization mechanism, a feeding mechanism, and a second equalization mechanism. The buffer tank 1 contains a storage bin and an equalization bin, with a discharge port 101 between them. The first equalization mechanism is located in the equalization bin and consists of a feeding roller 3 driven by a motor and rotatably connected to the equalization bin, and a guide seat 2 vibratingly connected to the bottom of the equalization bin. Multiple sets of feeding teeth 301 are evenly installed on the outer circumference of the feeding roller 3. The feeding roller 3 is located below the discharge port 101, and the guide seat 2 is located below the feeding roller 3. The feeding mechanism is located on one side of the buffer tank 1, and the discharge end of the guide seat 2 extends to the outside of the buffer tank 1 and connects with the feeding mechanism. The feeding end of the mechanism corresponds to the buffer box 1 and the mounting box 4 of the feeding mechanism, both of which are provided with openings corresponding to the guide seat 2 to avoid interfering with the vibration feeding of the guide seat 2; the second uniform material mechanism is connected to the discharge end of the feeding mechanism. The second uniform material mechanism consists of a uniform material pipe 405, a material distribution net 406 installed on the inner wall of the uniform material pipe 405, and a rotating shaft 5 rotatably connected to the material distribution net 406. The uniform material pipe 405 is connected to the discharge end of the feeding mechanism. The rotating shaft 5 is driven to rotate by a driving component installed on the uniform material pipe 405. An installation rod 501 is installed on the rotating shaft 5. Multiple sets of dispersing plates 502 are installed at the top of the installation rod 501, and multiple sets of agitating brushes 503 are installed at the bottom of the installation rod 501. The agitating brushes 503 are in contact with the material distribution net 406.

[0018] Furthermore, the bottom of the storage bin gradually decreases in height from a position far from the discharge port 101 to a position close to the discharge port 101, which facilitates the material entering the discharge port 101 along the inclined section and being conveyed towards the guide seat 2 by the feeding roller 3 and feeding teeth 301. When the material is difficult to move down along the inclined section, it is also convenient for the staff to use auxiliary tools to push the material along the inclined section towards the discharge port 101.

[0019] Furthermore, the guide seat 2 is inclined in the uniform material bin, and intercepting plates are provided on both sides of the guide seat 2. When the guide seat 2 vibrates, it is convenient to convey the material to the lower discharge port. The intercepting plates are also designed to prevent the material from falling to the bottom of the uniform material bin and failing to be conveyed out, thereby improving the feeding efficiency.

[0020] Furthermore, multiple sets of elastic elements 201 are provided between the bottom end of the guide seat 2 and the bottom end of the uniform material bin. The elastic element 201 consists of a telescopic rod and a spring sleeved on its outside. The telescopic rod guides the spring. If the nose tip guide seat 2 deviates, it will interfere with the material receiving. A vibrator is also installed at the bottom end of the guide seat 2. Through the cooperation of the vibrator and the elastic element 201, the guide seat 2 can be driven to vibrate vertically to convey the material towards the discharge port, thereby improving the feeding efficiency.

[0021] Furthermore, the driving components include a rotating rod 6, a protective box 601, and a transmission assembly; the rotating rod 6 is driven to rotate by a motor mounted on the material leveling pipe 405; the protective box 601 is mounted on the inner wall of the material leveling pipe 405, the rotating rod 6 is rotatably connected to the protective box 601, and the rotating shaft 5 is rotatably connected to the protective box 601. The protective box 601 facilitates the downward guidance of materials, preventing them from remaining on the protective box 601, and can also protect the transmission assembly; the transmission assembly is located in the inner cavity of the protective box 601, and the transmission assembly consists of two sets of meshing bevel gears, which are respectively mounted on the rotating shaft 5 and the rotating rod 6.

[0022] In this embodiment, the materials required for the biomass gasification furnace are temporarily stored in the storage bin inside the buffer tank 1. Since the buffer tank 1 is located at a low position, it facilitates the transportation of materials. The materials are pushed towards the discharge port 101 using auxiliary tools. The controller starts the motor to drive the feeding roller 3 to rotate at an appropriate speed, which drives multiple sets of feeding teeth 301 to flip the materials into the guide seat 2. The material discharge speed is adjusted by controlling the rotation speed of the feeding roller 3 to avoid material accumulation affecting the subsequent processing effect. The vibration motor and the elastic element 201 work together to drive the guide seat 2 to vibrate up and down along the uniform material bin, thereby moving the falling materials towards the discharge end. Simultaneously, the feeding mechanism is activated to receive the material discharged from the guide seat 2 and convey it to the second uniform material mechanism. The material finally enters the uniform material pipe 405. The controller activates the drive component to drive the rotating shaft 5 to rotate, which in turn drives the material falling from multiple sets of dispersing plates 502 to be quickly dispersed and fall onto the distribution net 406. After being dispersed by the distribution net 406, the material falls into the biomass gasifier. The second uniform material mechanism ensures that the material is in a uniform state when it enters the biomass gasifier, improving the efficiency of subsequent processing. The setting of the toggle brush 503 makes it easy to push the material remaining on the distribution net 406 downward into the biomass gasifier.

[0023] Example 2, as Figure 1 and Figure 4 As shown, the automatic feeding device for a biomass gasification furnace proposed in this utility model, compared with Embodiment 1, includes a feeding mechanism comprising a mounting box 4, a mounting base 402, a receiving box 403, and a guide pipe 404; the mounting box 4 is inclinedly installed on one side of the buffer box 1, and a belt conveyor mechanism 401 is provided inside the mounting box 4. The conveyor belt in the belt conveyor mechanism 401 can be set as a heavy-duty rubber belt or a steel chain plate belt, equipped with a high-power motor and a strong tensioning mechanism to prevent slippage or sagging; multiple sets of mounting bases 402 are provided, and multiple sets of mounting bases 402 are evenly installed on the conveyor belt in the belt conveyor mechanism 401; multiple sets of receiving boxes 403 are provided, and the receiving boxes 403 are installed on the mounting bases 402, and the receiving boxes 403 correspond to the discharge end of the guide seat 2; the guide pipe 404 is inclinedly installed at the discharge port of the mounting box 4, and the guide pipe 404 corresponds to the receiving box 403.

[0024] In this embodiment, when the feeding mechanism is working, the controller starts the belt conveyor 401, causing multiple sets of receiving boxes 403 to move along the belt conveyor 401. When the receiving box 403 moves to the position corresponding to the discharge end of the guide seat 2, the material in the guide seat 2 is discharged into the receiving box 403. As the belt conveyor 401 continues to work, the multiple sets of receiving boxes 403 are driven to the discharge port of the guide seat 2 to receive the material in sequence. When the receiving box 403 containing the material moves to the position close to the guide pipe 404, the discharge port of the receiving box 403 rotates to the downward direction, and the multiple sets of receiving boxes 403 discharge the material into the guide pipe 404 in sequence. By setting multiple sets of receiving boxes 403, it is convenient to intermittently convey the material to the second uniform material mechanism, providing time for the second uniform material mechanism to disperse the material and further improving the uniformity of feeding.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
