Description

Technical Field

[0001] This utility model relates to the field of biomass storage technology, specifically a storage bin for storing straw-based biomass. Background Technology

[0002] In the agricultural sector, straw biomass is an important renewable resource, and its storage and management are crucial. However, existing straw biomass storage facilities face numerous technical challenges.

[0003] In terms of ventilation, traditional storage warehouses rely primarily on natural ventilation, which is inefficient. Slow airflow within the warehouse prevents the timely removal of hot and humid gases, leading to a damp and stuffy environment. This easily causes localized temperature increases and mold growth in the straw, severely impacting the storage quality of straw-based biomass and resulting in resource waste.

[0004] In terms of loading and unloading operations, traditional storage warehouses lack efficient mechanized loading and unloading equipment, relying mainly on manual labor or simple handling tools, resulting in low loading and unloading efficiency and high labor intensity. At the same time, the warehouse floor lacks reasonable functional zoning, materials are piled up haphazardly, and space utilization is low, further reducing warehousing efficiency.

[0005] Therefore, in order to overcome these shortcomings of the existing technology, it is necessary to provide a new type of storage bin for storing straw-based biomass. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects of the prior art and provide a storage bin for storing straw biomass with good ventilation, efficient loading and unloading operations, and convenient monitoring and management.

[0007] To solve the above-mentioned technical problems, this utility model provides a storage bin for storing straw biomass, including a warehouse wall, a door, and a warehouse floor. The bottom of the warehouse wall is fixed to the warehouse floor, and a warehouse roof is provided on the top. The door is hinged to the side wall surface of the warehouse wall. Several air inlets are arranged longitudinally on both sides of the warehouse wall, and an exhaust fan is installed in each air inlet. The output end of the exhaust fan is connected to an air outlet pipe embedded in the warehouse floor. Multiple roof ventilators are provided on the top of the warehouse roof, and a track-type crane that can move along the length of the storage bin is provided below its truss.

[0008] Preferably, the air outlet duct includes a main air duct connected to the air inlet, and horizontal air distribution ducts are connected at intervals on the main air duct, with air outlet holes arranged on each horizontal air distribution duct.

[0009] Preferably, the rail-mounted overhead crane includes two I-beams that are parallel to each other on both sides of the warehouse wall. Each main beam is slidably connected to a front and rear movable seat via a first guide wheel. The first guide wheel is driven by a first drive motor located on the side of the movable seat.

[0010] An I-shaped crossbeam is erected between the front and rear movable seats on both sides. A transverse movable seat is slidably connected to the I-shaped crossbeam via a second guide wheel. The second guide wheel is driven by a second drive motor located on the side of the transverse movable seat. A winch is installed below the transverse movable seat, and the winch is connected to a gripper via a lifting rope.

[0011] Preferably, the gripper includes a gripper body with a rotary joint at the top, and arc-shaped grippers symmetrically hinged on both sides of its bottom. Gripper cylinders are rotatably provided on both sides of the gripper body, and the piston rod end of each gripper cylinder is rotatably connected to the middle of the corresponding arc-shaped gripper.

[0012] Preferably, the warehouse floor is divided into an unloading area near the door and a storage area in the middle. The storage area has matrix-arranged numbered areas on the ground, and reflective marking strips are laid at the boundaries of each numbered area.

[0013] Preferably, a removable filter screen is installed on the outside of the air inlet.

[0014] Preferably, the roof ventilator is a non-powered turbine ventilator with a dustproof grille at its bottom.

[0015] Preferably, multiple 360° panoramic cameras are arranged circumferentially on the inner side of the warehouse roof, and each 360° panoramic camera is connected to a central control console located outside the storage warehouse.

[0016] Compared with existing technologies, the storage bin for storing straw biomass in this application has significant advantages, mainly in terms of ventilation, monitoring and management, and loading and unloading operations.

[0017] Regarding the ventilation system, this application innovatively adopts a combined active and passive ventilation mode. Exhaust fans are arranged on both sides of the warehouse, working in conjunction with non-electric roof ventilators to accelerate airflow within the warehouse, promptly expelling hot and humid gases and preventing a stuffy and humid environment. Simultaneously, the main air ducts and distribution network embedded in the floor, aided by the exhaust fans, evenly deliver external air into the straw pile, achieving three-dimensional ventilation, effectively suppressing localized temperature rise and mold growth, and ensuring the storage quality of straw-based biomass.

[0018] For loading and unloading operations, the movable overhead cranes installed under the roof trusses enable efficient and mechanized loading, unloading, and stacking operations. The warehouse floor is divided into unloading and storage areas. The overhead crane system standardizes the work process, and combined with real-time monitoring by the monitoring system, it can significantly reduce space waste and greatly improve warehousing efficiency.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0028] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] Combined with appendix Figure 1 - Appendix Figure 5This utility model provides a storage bin for storing straw biomass, including a warehouse wall 1, a door 2, and a warehouse floor 3. The bottom of the warehouse wall 1 is fixed to the warehouse floor 3, and the top is provided with a warehouse roof 4. The door 2 is hinged to the side wall surface of the warehouse wall 1. Several air inlets 5 are arranged longitudinally on both sides of the warehouse wall 1, and each air inlet 5 is equipped with an exhaust fan 6. The output end of the exhaust fan 6 is connected to an exhaust pipe 7 embedded in the warehouse floor 3. Through the cooperation of the exhaust fan 6 and the exhaust pipe 7, forced circulation of air inside the bin can be achieved. The top of the warehouse roof 4 is provided with multiple roof ventilators 8, and a rail-mounted trolley 9 that can move along the length of the storage bin is provided below its truss. The rail-mounted trolley 9 provides convenience for the handling and sorting of materials inside the bin.

[0030] The exhaust duct 7 employs a unique design to ensure even air distribution within the straw pile. Specifically, the exhaust duct 7 includes a main duct 701 connected to the air inlet 5, with transverse distribution ducts 702 spaced at intervals on the main duct 701. Each transverse distribution duct 702 has an exhaust port. The spacing between the transverse distribution ducts 702 is 2-3 meters, with a diameter of DN200-DN300, and a single air inlet diameter of 50-100mm. When the induced draft fan 6 is activated, external air is drawn in and evenly distributed into the straw pile through the exhaust ports on the surface of the distribution ducts 702, creating forced ventilation. Simultaneously, the non-electric roof ventilator 8 on the outside of the warehouse roof 4 utilizes natural wind or the principle of hot air rising to expel humid and hot gases from the warehouse, creating natural ventilation. By rationally arranging the air distribution network, it is ensured that air is evenly distributed throughout the straw pile, effectively suppressing localized temperature rise and mold growth, and guaranteeing the storage quality of straw biomass.

[0031] In one embodiment, the rail-mounted overhead crane 9 possesses flexible mobility to meet the material handling needs at different locations within the warehouse. The rail-mounted overhead crane 9 includes two I-beam main beams 901 parallel to each other on both sides of the warehouse wall 1. Each main beam 901 has a front-to-back moving seat 903 slidably connected to it via a first guide wheel 902. The first guide wheel 902 is driven by a first drive motor 904 located on the side of the moving seat, allowing the front-to-back moving seat 903 to move back and forth along the main beam 901. An I-beam crossbeam 905 is erected between the front-to-back moving seats 903 on both sides. A transverse moving seat 907 is slidably connected to this I-beam crossbeam 905 via a second guide wheel 906. The second guide wheel 906 is driven by a second drive motor 908 located on the side of the transverse moving seat 907, allowing the transverse moving seat 907 to move laterally along the I-beam crossbeam 905. A winch 909 is installed below the transverse moving seat 907. The winch 909 is connected to the gripper 10 via a lifting rope 910. Through the cooperation of the winch 909 and the lifting rope 910, the lifting operation of the gripper 10 can be realized, thereby completing the gripping and handling of materials.

[0032] Furthermore, the gripper 10 has a reasonable structural design, enabling it to stably and reliably grasp straw-like biomass. The gripper 10 includes a gripper body 101 with a rotary joint at the top, and symmetrically hinged arc-shaped grippers 102 on both sides of its bottom. Gripper cylinders 103 are rotatably mounted on both sides of the gripper body 101, with the piston rod end of each cylinder 103 rotatably connected to the middle of the corresponding arc-shaped gripper 102. When the gripper cylinder 103 actuates, the extension and retraction of the piston rod causes the arc-shaped gripper 102 to rotate around the hinge point, thereby realizing the opening and closing action of the gripper 10 and completing the grasping and release of straw-like biomass.

[0033] In one embodiment, the warehouse floor 3 is rationally divided into zones to improve the efficiency and accuracy of warehouse management. The warehouse floor 3 is divided into an unloading area 301 near the door 2 and a storage area 302 in the middle. The unloading area 301 facilitates rapid unloading of materials, while the storage area 302 is used for long-term material storage. The storage area 302 has 12 numbered zones arranged in a matrix. Reflective markings are laid at the boundaries of each numbered zone 303. The use of these numbered zones and reflective markings enables precise positioning and management of materials within the storage area, reducing the difficulty of manual inspection.

[0034] Specifically, a removable filter screen is installed on the outside of air inlet 5. This filter screen can effectively block external dust, debris, and other contaminants from entering the storage chamber, preventing pollution of the straw-like biomass inside. At the same time, the removable design facilitates cleaning and replacement of the filter screen, ensuring its filtration effect.

[0035] Roof ventilator 8 is a non-powered turbine ventilator, which has advantages such as energy saving and environmental protection. The bottom of this non-powered turbine ventilator is equipped with a dustproof grille, which can prevent dust, debris and other objects from entering the ventilator and affecting its normal operation, while ensuring the ventilation effect of the ventilator.

[0036] In one embodiment, multiple 360° panoramic cameras 11 are arranged circumferentially on the inner side of the warehouse roof 4, and each 360° panoramic camera 11 is connected to a central control console located outside the storage warehouse. The 360° panoramic cameras 11 installed on the inner side of the warehouse roof are used to monitor the internal environment and straw stacking status in real time. The 360° panoramic cameras 11 are connected to the monitoring system via a network, and managers can view real-time images through the monitoring platform to promptly detect abnormalities (such as localized overheating, water seepage, etc.). Combined with the numbered areas divided on the storage area floor and the reflective marking strips, precise location management of materials inside the warehouse can be achieved, further reducing the difficulty of manual inspection and improving the management efficiency and security of the storage warehouse.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
