[0002] Biomass pellets are made by cold-forming and compacting pulverized biomass straw, forestry waste, and other raw materials using rollers and ring dies at room temperature. The formed pellets are easy to store and transport, and significantly improve the combustion performance of the biomass. However, after processing, biomass pellets often need to be stored, but existing biomass pellet storage silos present several problems:

[0003] Poor ventilation. In the rainy spring and summer seasons, in addition to fire and moisture prevention, warehouse ventilation and dehumidification are also important. If the humidity in the air is higher than the moisture content of the biomass pellets, the pellets will absorb additional moisture, which will reduce their calorific value and affect combustion efficiency. However, existing storage silos cannot effectively ventilate the stored biomass pellets. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1:

[0026] A storage bin for biomass pellet processing, in this embodiment, Figure 1-4As shown, it includes a storage tank 1, the top outer wall of the storage tank 1 is hinged with a circular sealing cover 2, and a feed hopper 3 is welded to one side of the top of the circular sealing cover 2, one end of the feed hopper 3 is rotatably provided with a rotating shaft 4, and a sealing cover plate 5 is welded to the top outer wall of the rotating shaft 4, a worm gear 6 is welded to the bottom outer wall of the rotating shaft 4, and a worm 7 is meshed with one side of the worm gear 6, one end of the worm 7 is connected to the output shaft of the servo motor 8, and a temperature sensor 9 is fixed to the inner wall of the storage tank 1, a rotating stirring tube 10 is rotatably installed on the bottom inner wall of the storage tank 1, and the outer wall of the rotating stirring tube 10 is provided with equidistantly distributed ventilation holes 11, the outer wall of the rotating stirring tube 10 is welded with equidistantly distributed stirring blades 12 in a spiral direction, and an outer tooth ring 18 is welded to the bottom outer wall of the rotating stirring tube 10, one side of the outer tooth ring 18 is meshed and driven by a driving gear 19, and a driving motor 20 is connected to the bottom axis of the driving gear 19;

[0027] By setting a temperature sensor 9 inside the storage tank 1, the internal temperature of the accumulated biomass particles can be fed back in real time, and the rotating stirring tube 10 that continuously pumps air can quickly pump out the high-temperature gas inside, thereby reducing the internal temperature of the storage tank 1 and preventing the biomass particles from igniting due to excessive temperature.

[0028] The inner wall of the rotating stirring tube 10 is plugged with a cross-shaped drying filter element 13, and the size of the cross-shaped drying filter element 13 is adapted to the size of the inner wall of the rotating stirring tube 10. A card cover 14 is fixed to the bottom outer wall of the rotating stirring tube 10. A cylindrical shell 16 is rotatably mounted on the bottom outer wall of the rotating stirring tube 10, and an exhaust pipe 17 is connected to the inner wall of one side of the cylindrical shell 16. The outer wall of the rotating stirring tube 10 located inside the cylindrical shell 16 is provided with rectangular through-slots 15 distributed at equal distances.

[0029] A first magnet is embedded in the outer wall of one end of the top of the feed hopper 3, and a second magnet is embedded in the outer wall of one end of the bottom of the sealing cover plate 5. The first magnet and the second magnet have different magnetic properties.

[0030] The bottom of the storage tank 1 is a frustum-shaped structure, and a discharge pipe is welded to the inner wall of the bottom of the storage tank 1;

[0031] When storing biomass particles, a cross-shaped drying filter element 13 is provided inside the rotating stirring tube 10, so that the moisture inside the storage tank 1 can be absorbed and dried, and a rotatable stirring blade 12 is provided inside, so that the flow of particles can be accelerated during the unloading process to avoid blockage.

[0032] When using this embodiment, the storage bin is first assembled and the cross-shaped drying filter element 13 is inserted into the interior of the rotating stirring tube 10, and the bottom is fixed with a card cover 14. After completion, the servo motor 8 is used to drive the worm 7 to rotate, thereby driving the bottom worm wheel 6 to rotate, and the sealing cover 5 is rotated to open. Then, the biomass particles to be stored are directly introduced into the interior of the feed hopper 3 to complete the loading. After the loading is completed, the sealing cover 5 is closed, and the temperature sensor 9 is started to monitor the internal temperature of the storage bin 1 in real time. When the humidity of the biomass particles is high, the moisture will pass through the ventilation hole 11. It is absorbed by the cross-shaped drying filter element 13 to complete the drying process of the biomass particles. When the internal temperature is too high, the top sealing cover plate 5 is rotated open a little, and the air is extracted from the inside of the exhaust pipe 17 by using the vacuum pump, so that the high-temperature gas inside the storage tank 1 is extracted and discharged from the inside of the rotating stirring tube 10, and the external low-temperature air is replaced, thereby achieving cooling and heat dissipation. When unloading is required, in order to improve the fluidity of the particles, the bottom drive motor 20 is started to use the gear ratio with increased torque to drive the stirring blade 12 to rotate slowly, thereby accelerating the discharge of biomass particles to complete unloading.

[0033] Example 2:

[0034] A storage bin for biomass pellet processing, such as Figure 1-4 As shown, this embodiment makes the following supplements on the basis of Example 1: the servo motor 8, temperature sensor 9 and drive motor 20 are all connected to the PLC controller via signal lines, and the PLC controller is connected to an external power supply via wires, an annular sealing groove is formed on the top outer wall of the feed hopper 3, and an annular sealing ring is bonded to the inner wall of the annular sealing groove, and the effective number of teeth of the outer gear ring 18 and the effective number of teeth of the drive gear 19 are 1:2;

[0035] When this embodiment is used, during the process of loading the biomass particles, the top sealing cover plate 5 can be driven to rotate by controlling the rotation of the servo motor 8, thereby avoiding manual climbing to open the cover, greatly facilitating the loading speed and ensuring overall safety.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
