Description

Technical Field

[0001] This utility model relates to the field of biomass storage technology, specifically a biomass straw transport vehicle. Background Technology

[0002] my country's rural areas face challenges in managing crop straw, with traditional methods having many drawbacks. Direct burning results in resource waste and air pollution, releasing 3 kg of PM2.5 per ton of straw burned; as fuel for stoves, unprocessed straw has a low calorific value utilization rate of less than 30%; and as animal feed, due to a lack of refined processing, its digestibility is less than 40%, leading to poor nutrient absorption.

[0003] To improve resource utilization efficiency, high-quality and industrialized straw application models have emerged, relying on centralized operations in large factories with transportation radii of 200-500 kilometers. However, straw pellet storage and transportation systems face significant problems. The raw material supply is affected by the contradiction between the seasonality of crop harvesting and the year-round utilization of biomass, and the traditional centralized storage and transportation model has obvious shortcomings. Open-air storage requires large storage space, moisture content is prone to exceed standards during the rainy season, and the bottom layer has a high mold rate when the pile height exceeds 6 meters. There is also a large annual loss of calorific value and the risk of spontaneous combustion, threatening supply stability and affecting the economics of the project.

[0004] Furthermore, the existing transportation system poses significant safety hazards. Mainstream box trailers rely on fully enclosed transport, and the high stacking of baled straw leads to poor ventilation within the trailer. This results in low oxygen levels and high temperatures in the confined space, making the low-moisture straw prone to smoldering. Clearly, existing straw transport equipment suffers from inadequate ventilation and heat dissipation, failing to effectively address safety issues such as smoldering and spontaneous combustion during transport. Therefore, there is an urgent need for a biomass straw transport device that improves ventilation and reduces safety risks. This utility model provides a corresponding solution to address these technical deficiencies. Utility Model Content

[0005] This utility model addresses the technical challenges of poor or uneven ventilation and high risk of spontaneous combustion during the transportation or temporary storage of biomass straw. It proposes a biomass straw transport vehicle that significantly improves transportation safety and material quality through structural innovation and functional integration.

[0006] To solve the above-mentioned technical problems, this utility model provides a biomass straw transport vehicle, comprising:

[0007] The rectangular carriage body has a horizontally fixed air distribution plate on the inner side of its top, which divides the rectangular carriage body into an upper air chamber and a lower storage chamber.

[0008] The front wall of the air chamber is provided with an air inlet, which is connected to an induced draft fan;

[0009] Waterproof louvers are symmetrically arranged on the lower part of the two side walls and the bottom of the rear door of the storage room;

[0010] The air distribution plate has a matrix of ventilation holes to allow airflow communication between the air chamber and the storage chamber.

[0011] The four edges of the air distribution plate are perpendicularly attached to the inner wall of the carriage body to form a sealed structure, so that airflow can only flow between the air chamber and the storage chamber through the ventilation holes.

[0012] Preferably, three waterproof louvers are evenly arranged on the lower part of the two side walls of the storage compartment along the length of the rectangular carriage body, and one waterproof louver is provided at the bottom of each rear door. The ventilation opening of the waterproof louvers is a flat rectangle.

[0013] Preferably, the waterproof louver is an openable and closable structure with an adjustable blade tilt angle of 0-60°, and a dust filter is provided inside the waterproof louver.

[0014] Preferably, the front of the carriage body is provided with a deflector, the lower front end of the deflector is provided with an air inlet, the air inlet is connected to the air inlet of the air chamber through a ventilation duct, and the rear end of the deflector is also provided with a dehumidification hole.

[0015] Preferably, a dustproof net is provided at the outer end of the air inlet.

[0016] Preferably, the ventilation duct is equipped with a drying box, which has air vents evenly distributed on it and is filled with a certain amount of desiccant.

[0017] Preferably, the ventilation holes of the air distribution plate are composed of two sections: the upper section is a straight hole section with a diameter of 5-10cm;

[0018] The lower section is a tapered hole section, with the hole wall forming an angle of 15-25° with the horizontal direction; the center-to-center distance between adjacent ventilation holes is 20-50cm.

[0019] Preferably, the inner wall surface of the storage chamber is coated with an anti-mildew coating, which is an epoxy resin composite material containing nano zinc oxide, and its thickness is 50-100μm.

[0020] Compared with the prior art, the carriage of this utility model that facilitates the transportation of biomass straw has the following advantages:

[0021] 1. Add auxiliary fan and airflow guiding device: Integrate the exhaust fan into the ventilation unit to force air into the carriage body and exhaust it through louvers, so that the gas circulates in the carriage body to effectively improve the ventilation effect of the carriage body, enhance forced convection, and ensure heat dissipation, especially when driving at low speed or when statically stacked, and reduce the risk of spontaneous combustion.

[0022] 2. The special design of the ventilation holes facilitates uniform air distribution. Appropriately increasing the resistance of the air distribution panel improves ventilation at the rear of the compartment, allowing air entering the storage room to be distributed more evenly to all corners, preventing dead zones. Simultaneously, the wide-inlet, narrow-outlet design effectively increases airflow velocity within the storage room, aiding in heat dissipation. Furthermore, the air distribution panel is located at the top of the compartment and does not bear weight; its sole focus is on the uniformity of air distribution. This allows for greater flexibility in the selection of metal materials for the air distribution panel, enabling the selection of more suitable and economical materials based on actual needs, thus reducing production costs.

[0023] 3. This straw storage and transportation device is completely sealed to prevent raw material leakage, effectively protect against external open flames and rainwater, while ensuring good ventilation to prevent biomass straw decay. Manual intervention is possible when necessary to further guarantee straw quality. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] Combined with appendix Figure 1 - Appendix Figure 5 To solve the above-mentioned technical problems, this utility model provides a biomass straw transport vehicle, comprising:

[0035] The rectangular carriage body 1 has a horizontally fixed air distribution plate 2 on the inner side of its top, which divides the rectangular carriage body 1 into an upper air chamber 3 and a lower storage chamber 4.

[0036] The front wall of the air chamber 3 is provided with an air inlet 31, and the air inlet 31 is connected to the induced draft fan 5;

[0037] Waterproof louvers 6 are symmetrically arranged on the lower part of the two side walls and the bottom of the rear door of the storage room 4;

[0038] The air distribution plate 2 has a matrix of ventilation holes 21 for airflow communication between the air chamber 3 and the storage chamber 4.

[0039] The air distribution plate 2 is welded perpendicularly to the inner wall of the carriage body 1 to form a sealed structure, so that airflow can only flow between the air chamber 3 and the storage chamber 4 through the ventilation hole 21.

[0040] To ensure good ventilation and waterproofing of the storage compartment 4, three waterproof louvers 6 are evenly arranged along the length of the rectangular compartment body 1 on the lower part of both side walls of the storage compartment 4, and one waterproof louver 6 is also provided at the bottom of each rear door. By rationally arranging the waterproof louvers 6 on the side walls and at the bottom of the rear door, good air exchange between the storage compartment 4 and the outside environment can be achieved, effectively removing moisture and heat. The ventilation openings of the waterproof louvers 6 are designed as flat rectangles, a shape that facilitates airflow while reducing rainwater ingress. The louver blades are made of waterproof materials, such as specially treated plastic or metal, to prevent rainwater penetration. Furthermore, the waterproof louvers 6 can be opened and closed manually or electrically. In inclement weather, the waterproof louvers 6 can be closed to prevent rainwater from entering; when ventilation is needed, the waterproof louvers 6 can be opened to meet ventilation requirements, thus adapting to different weather conditions and ventilation needs.

[0041] To further improve the performance of the waterproof louver 6, the waterproof louver 6 is an openable and closable structure with an adjustable blade tilt angle ranging from 0 to 60°. By adjusting the blade tilt angle, the ventilation volume can be flexibly controlled according to actual ventilation needs and weather conditions. For example, when the weather is good and a larger ventilation volume is required, the blade tilt angle can be increased; when the wind is strong or a reduced ventilation volume is needed, the blade tilt angle can be decreased. In addition, the waterproof louver 6 is equipped with a dust filter, which can effectively block external dust and impurities from entering the storage chamber 4, preventing dust from accumulating on the straw and affecting its quality, while also reducing the impact on the ventilation system.

[0042] To optimize the ventilation system of the carriage, a deflector 7 is provided at the front of the carriage body 1. The design of the deflector 7 guides airflow and improves ventilation efficiency. An air inlet 71 is opened at the lower front end of the deflector 7, and the air inlet 71 is connected to the air inlet 31 of the air chamber 3 through a ventilation duct 72. In this way, during transportation, outside air can smoothly enter the deflector 7 and enter the air chamber 3 through the ventilation duct 72. At the same time, a dehumidification hole 73 is also provided at the rear end of the deflector 7. The dehumidification hole 73 helps to expel moisture and prevent moisture from accumulating inside the deflector 7.

[0043] To prevent dust and other impurities from entering the ventilation system, a dustproof net is provided at the outer end of the air inlet 71. The dustproof net can effectively filter dust, leaves and other impurities in the air, preventing these impurities from entering the ventilation duct 72 and the air chamber 3 and affecting the normal operation of the ventilation system. At the same time, it can also ensure that the air entering the storage chamber 4 is relatively clean, reducing pollution to biomass straw.

[0044] To remove moisture from the air entering the compartment and prevent the straw from getting damp, a drying box 8 is installed inside the ventilation duct 72. The drying box 8 has evenly distributed ventilation holes and is filled with a certain amount of desiccant. The desiccant absorbs moisture from the air, keeping the air entering the storage chamber 4 dry. In practice, to facilitate the replacement of the desiccant inside the drying box 8, the drying box 8 is designed to be pulled out and connected to the ventilation duct 72. The side of the air guide shroud 7 is sealed with a bolted, openable cover. When it is necessary to replace the desiccant, the drying box 8 can be pulled out by removing the cover, allowing for convenient and quick replacement and ensuring the drying effect.

[0045] Preferably, to improve the air distribution effect of the air distribution plate 2, the ventilation holes 21 of the air distribution plate 2 are composed of two sections: the upper section is a straight hole section 211 with a diameter of 5-10cm; the lower section is a conical hole section 212 with an angle of 15-25° between the hole wall and the horizontal direction; the center-to-center distance between adjacent ventilation holes 21 is 20-50cm. This specially designed ventilation hole 21 has many advantages. The straight hole section 211 ensures that the airflow enters the ventilation hole 21 smoothly, while the conical hole section 212 accelerates the airflow and diffuses it evenly to the storage chamber 4. The special design of the ventilation hole 21 is conducive to uniform air distribution, and appropriately increasing the resistance of the air distribution plate 2 improves the ventilation at the rear of the carriage. The air entering the storage chamber 4 can be more evenly distributed to all corners without forming dead zones. At the same time, the wide-inlet and narrow-outlet design can effectively increase the airflow velocity in the storage chamber, which helps the carriage to dissipate heat. In addition, the air distribution plate is arranged on the upper part of the carriage and does not bear weight; only the uniformity of air distribution is considered. This makes the selection of metal materials for the air distribution plate more flexible, allowing for the selection of more suitable and economical materials based on actual needs, thereby reducing production costs.

[0046] To prevent the biomass straw in storage chamber 4 from becoming damp and moldy, the inner wall surface of storage chamber 4 is coated with an anti-mold coating. This anti-mold coating is an epoxy resin composite material containing nano-zinc oxide. Nano-zinc oxide has excellent antibacterial and anti-mold properties, effectively inhibiting mold growth. Its thickness is 50-100 μm, a thickness that ensures anti-mold effectiveness without adding excessive cost or weight. By applying the anti-mold coating, a relatively dry and hygienic storage environment can be provided for the biomass straw, extending its storage time.

[0047] Working principle: Compressed or baled biomass straw is loaded into the storage compartment from the rear of the truck bed. The working state of the blower 6 is adjusted according to the transportation conditions (such as vehicle speed, ambient temperature and humidity).

[0048] 1. Activation of the exhaust fan mode: During transportation, if the temperature inside the rectangular carriage 1 rises or forced ventilation is required, the exhaust fan 5 is activated. External air is drawn in through the air inlet 71 of the air guide hood 7, first passing through a dust filter to remove dust and other impurities. Then, the air passes through the drying box 8, where the desiccant absorbs moisture from the air, drying it. The dried air enters the air chamber 3, and then evenly enters the storage chamber 4 through the ventilation holes 21 of the air distribution plate 2. The airflow penetrates downwards through the straw layer, carrying away heat and moisture, and finally exits through the waterproof louvers 6 at the bottom of the storage chamber 4, thus achieving ventilation, dehumidification, and cooling of the storage chamber 4.

[0049] 2. Natural Ventilation Mode: When the vehicle is traveling at high speed, the exhaust fan 5 is turned off. The negative pressure created by the external airflow of the rectangular carriage body 1 allows hot air inside the storage compartment 4 to be naturally exhausted through the waterproof louvers 6. At this time, the waterproof louvers 6 can adjust their blade angle according to actual ventilation needs to control the ventilation volume. This natural ventilation mode can reduce energy consumption.

[0050] 3. Static Stacking Management Mode: If the truck needs to be temporarily parked, turn on the exhaust fan 5 and some of the waterproof louvers 6 to maintain forced convection. Forced convection can prevent local temperature rise from causing smoldering and ensure the safe storage of biomass straw.

[0051] 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.
