[0002] Biochar is a type of charcoal used as a soil conditioner. It helps plants grow and can be used in agriculture as well as for carbon collection and storage. Unlike traditional charcoal used as fuel, biochar requires cooling after carbonization during production.

[0003] However, during the drying and storage process, existing biochar storage silos can slowly release gases such as CO and CH4 due to the high carbon content of biochar. These gases can form an explosive mixture in a confined space, which can easily cause an explosion when exposed to static electricity, thus posing a certain safety hazard. Therefore, it is necessary to provide a new type of biochar storage silo to solve the above-mentioned technical problems. Utility Model Content

[0004] Purpose of the invention: The purpose of this utility model is to provide a biochar storage bin to solve the problem that existing biochar storage bins, during the drying and storage process, due to the high carbon content of biochar, can slowly release gases such as CO and CH4 during transportation, forming an explosive mixture in a confined space. When encountering static electricity, this mixture can easily cause an explosion, thus posing a certain safety hazard.

[0005] Technical solution: A biochar storage bin includes: a chassis, a storage bin fixedly connected to the upper surface of the chassis, a feed pipe inserted into the right side of the upper surface of the storage bin, a fixed cover installed at the upper end of the feed pipe, and drying mechanisms installed at the front and rear ends of the upper surface of the storage bin.

[0006] A stirring mechanism is installed inside the storage chamber. A pressure regulating valve is installed on the left side of the upper surface of the storage chamber. A mounting frame is fixedly connected to the upper left side of the storage chamber. An air injection mechanism is installed in the middle of the mounting frame. A discharge pipe is inserted into the bottom right side of the storage chamber. A valve is installed at the upper end of the discharge pipe.

[0007] As a further description of the above technical solution: the drying mechanism includes placement boxes installed at the front and rear ends of the upper surface of the storage chamber, a sealing ring is fixedly connected to the top of the placement box, and a sealing cover is engaged in the middle of the upper end of the placement box.

[0008] As a further description of the above technical solution: the storage compartment has a movable slot adapted to the placement box, and the outer surface of the placement box has several ventilation holes in the middle.

[0009] As a further description of the above technical solution: the stirring mechanism includes a motor installed in the middle of the upper surface of the storage bin, a fixing plate fixedly connected to the right side of the motor and fixedly connected to the storage bin, a rotating rod connected to the power output end of the motor and passing through the storage bin, connecting rods fixedly connected to the upper and lower ends of the rotating rod, an anti-static cleaning brush installed on the side of the connecting rod away from each other, and two sets of stirring blades installed in the middle of the connecting rod.

[0010] As a further description of the above technical solution: the antistatic cleaning brush is attached to the inner wall of the storage compartment.

[0011] As a further description of the above technical solution: the gas injection mechanism includes an ammonia tank mounted on a mounting frame, an air pump is installed in the middle of the upper surface of the ammonia tank, an injection pipe is connected in the middle of the air pump, and the other end of the injection pipe is connected to the storage chamber.

[0013] As a further description of the above technical solution: the inner wall of the storage compartment is coated with an antistatic coating.

[0014] Beneficial effects: 1. By setting up an injection mechanism, the ammonia gas in the ammonia tank is adsorbed by an air pump and transported into the storage chamber through the injection pipe, so that it covers the liquid surface and isolates the air, thus avoiding the release of CO, CH4 and other gases from the biochar. By setting up a pressure regulating valve, when the internal air pressure is too high during injection, the excess air inside the storage chamber is discharged, which improves the stability of the transportation of this device.

[0015] 2. By incorporating a drying mechanism, a drying block is placed in a placement box, facilitating the drying and use of biochar in the storage chamber. When the drying block needs to be replaced, simply lift the placement box slightly upwards, open the sealing cover, and replace the drying block. This seals the placement box and storage chamber, reducing the entry of external air into the storage chamber, keeping the storage chamber dry at all times, and preventing the release of injected ammonia gas, thus avoiding unnecessary waste.

[0026] Working principle: The chassis 1 and storage bin 2 facilitate component installation; the feed pipe 3 and fixed cover 4 facilitate sealing after feeding; the drying mechanism 5 facilitates drying of the material in the storage bin 2; the stirring mechanism 6 facilitates stirring in the storage bin 2 to prevent biochar from clumping and adhering to the inner wall of the storage bin 2; the pressure regulating valve 7 facilitates adjustment of the internal air pressure of the storage bin 2; the mounting bracket 8 facilitates installation of the gas injection mechanism 9; the gas injection mechanism 9 delivers ammonia gas into the storage bin 2 to cover the liquid surface and isolate it from air; the discharge pipe 11 and valve 12 facilitate the discharge of the stored biochar.

[0027] Example 2

[0028] Reference Figure 3 and Figure 4 This embodiment addresses the safety hazard posed by existing biochar storage bins during the drying and storage process. Due to the high carbon content of biochar, it slowly releases gases such as CO and CH4 during transportation, forming an explosive mixture in a confined space. This mixture is prone to explosion when exposed to static electricity. The proposed biochar storage bin further includes a drying mechanism 5 comprising placement boxes 501 mounted at the front and rear ends of the upper surface of the storage bin 2. A sealing ring 502 is fixedly connected to the top of each placement box 501, and a sealing cover 503 is engaged at the upper center of each placement box 501. The storage bin 2 has a movable slot adapted to the placement box 501, and several ventilation openings 504 are provided on the outer surface of the placement box 501. A stirring mechanism 6 includes a motor 601 mounted in the center of the upper surface of the storage bin 2. A fixing plate 602 is fixedly connected to the right side of the motor 601. The motor 601 is fixedly connected to the storage chamber 2. The power output end of the motor 601 is connected to a rotating rod 603, which passes through the storage chamber 2. The upper and lower ends of the rotating rod 603 are fixedly connected to connecting rods 604. An antistatic cleaning brush 605 is installed on the side of the connecting rods 604 that are far apart from each other. Two sets of stirring blades 606 are installed in the middle of the connecting rods 604. The antistatic cleaning brush 605 is in contact with the inner wall of the storage chamber 2. The gas injection mechanism 9 includes an ammonia tank 901 installed on the mounting frame 8. An air pump 902 is installed in the middle of the upper surface of the ammonia tank 901. An air injection pipe 903 is connected in the middle of the air pump 902, and the other end of the air injection pipe 903 is connected to the storage chamber 2. The upper outer surface of the feed pipe 3 is connected with threads. The fixed cover 4 has a threaded groove that matches the threads. The feed pipe 3 and the fixed cover 4 form a rotating connection mechanism. The inner wall of the storage chamber 2 is sprayed with an antistatic coating 10.

[0029] Working Principle: When using this device, the biochar to be stored is placed into the storage chamber 2 through the feed pipe 3. The fixing cover 4 is then tightened to ensure a sealed interior. After storage, the air pump 902 is turned on to adsorb the ammonia gas in the ammonia tank 901. The ammonia gas is then transported into the storage chamber 2 through the air injection pipe 903, covering the liquid surface and isolating it from air to prevent the release of CO, CH4, and other gases from the biochar. A pressure regulating valve 7 is installed to release excess air from the storage chamber 2 when the internal pressure becomes too high during injection, improving the stability of the device's transport. After ammonia gas is injected into the storage chamber 2 and the stability of the biochar inside is ensured, the motor 601 is turned on, driving the rotating rod 603 to rotate, causing the anti-static cleaning brush 60... The stirring plate 606 rotates and stirs the biomass char, facilitating the drying of the biomass char with the drying block in the placement box 501 and cleaning the inner wall of the storage chamber 2 to prevent the biomass char from adhering to the inner wall of the storage chamber 2 and making it difficult to discharge. The anti-static cleaning brush 605 and the anti-static coating 10 ensure anti-static treatment during the stirring process, improving the safety of the device. When the drying block needs to be replaced, simply lift the placement box 501 up a bit, open the sealing cover 503, and replace the drying block, so that the placement box 501 and the storage chamber 2 are sealed, reducing the entry of external air into the storage chamber 2, keeping the storage chamber 2 dry at all times, and preventing the release of injected ammonia gas, which would cause unnecessary waste. When the biomass char needs to be discharged, open the valve 12 and discharge the biomass char through the discharge pipe 11.
