Description

Technical Field

[0001] This utility model relates to the field of grain storage silo technology, and in particular to a ventilation device for a grain storage silo. Background Technology

[0002] Grain storage silos are buildings or facilities specifically designed for storing grain. Their primary purpose is to efficiently store large quantities of grain, ensuring its quantity, quality, and storage safety. The design and construction of grain storage silos take into account factors such as moisture control, insect control, and rodent control to ensure that the quality of the grain is not compromised during storage.

[0003] Grain undergoes respiration during storage, releasing heat in the process. If this heat cannot be dissipated in time, the temperature inside the warehouse will rise, affecting the storage quality of the grain and even causing it to rot. Therefore, ventilation systems can help dissipate this heat, maintain a suitable temperature inside the warehouse, and extend the storage time of the grain.

[0004] Inside grain storage silos, grain stacking can negatively impact ventilation in several ways. First, excessively high or dense stacking reduces the gaps between grains, increasing airflow resistance. Irregular stacking shapes also create winding and narrow airflow paths. Second, differences in permeability due to varying locations and stacking methods result in uneven ventilation; areas near vents and the surface of the grain pile have better ventilation, while areas further away and at the bottom have poorer ventilation. Finally, lumpy structures created by stacking or the introduction of debris can form dead zones where air cannot reach. All these factors combined reduce ventilation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a ventilation device for grain storage silos, which solves the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a ventilation device for a grain storage silo, comprising a storage silo body, a top pipe, and a fan. The top pipe is installed at the top of the storage silo body, and the fan is installed at the rear end of the top of the storage silo body. A ventilation pipe is installed at the exhaust end of the fan, and one end of the ventilation pipe is connected to the top of the top pipe. An internal pipe is installed in the middle of the storage silo body, and the top end of the internal pipe protrudes from the top of the storage silo body and is connected to the top pipe. Side pipes are arranged around the internal pipe, and an internal groove is opened inside the internal pipe. The ventilation pipe is connected to the inside of the internal groove. A side cavity is opened inside the side pipe, and the internal groove is connected to the inside of the side cavity.

[0007] Preferably, air guide grooves are provided on both sides of the side pipe, and a bottom groove is provided at the bottom end of the side pipe. Both the air guide grooves and the bottom groove are connected to the side cavity.

[0008] Preferably, the air guide ducts are arc-shaped and are evenly spaced on both sides of the side pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model provides a ventilation device for a grain storage silo. A tree-like ventilation duct system, consisting of an internal pipe and side pipes, is placed inside the main body of the silo, greatly optimizing ventilation. When grain is poured into the silo, the duct extends deep into the grain pile, directly delivering air to all areas inside the grain pile compared to traditional external ventilation methods. After the fan is started, air flows along the ventilation duct into the internal groove of the internal pipe, is then dispersed through the side cavity, and precisely blown outwards from the side pipes. This deep ventilation ensures uniform airflow exchange for the grain, both on the surface and deep layers, effectively preventing problems such as localized dampness and overheating caused by uneven ventilation. It ensures that the temperature and humidity of the entire grain pile remain within a suitable storage range, significantly extending the grain's storage life.

[0011] 2. This utility model provides a ventilation device for a grain storage silo. Through a clever design of arc-shaped air guide channels and a vertically downward-facing bottom trough, it provides a solid guarantee for the stable operation of the ventilation system. For the arc-shaped air guide channels, when grain shifts due to handling or flow within the silo, its unique arc structure guides the grain particles to slide down the surface instead of falling directly into the channel, reducing the risk of blockage at the source. Meanwhile, when the fan starts ventilation, the vertically outward-spraying airflow from the bottom trough forms a natural protective barrier, preventing grain falling vertically under gravity from entering the trough. This anti-blockage design not only ensures continuous ventilation, preventing ventilation interruptions due to blockage and subsequent deterioration of the local environment of the grain storage silo, but also reduces the frequency of equipment maintenance, lowers operating costs, and makes the ventilation management of the entire grain storage silo more efficient and convenient.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figures 1 to 5 As shown, the present invention discloses a ventilation device for a grain storage silo, comprising a storage silo body 1, a top pipe 2, and a fan 3. The top pipe 2 is installed at the top of the storage silo body 1, and the fan 3 is installed at the rear end of the top of the storage silo body 1. A ventilation pipe 31 is installed at the exhaust end of the fan 3, and one end of the ventilation pipe 31 is connected to the top of the top pipe 2. An internal pipe 21 is installed in the middle of the storage silo body 1, and the top end of the internal pipe 21 protrudes from the top of the storage silo body 1 and is connected to the top pipe 2. Side pipes 22 are arranged around the internal pipe 21, and an internal groove 23 is opened inside the internal pipe 21. The ventilation pipe 31 is connected to the interior of the internal groove 23. A side cavity 24 is opened inside the side pipe 22, and the internal groove 23 is connected to the interior of the side cavity 24.

[0021] The side tube 22 has air guide grooves 241 on both sides and a bottom groove 242 at the bottom end. Both the air guide grooves 241 and the bottom groove 242 are connected to the side cavity 24. The air guide grooves 241 are arc-shaped and are evenly spaced on both sides of the side tube 22.

[0022] Working principle:

[0023] The built-in pipe 21 and the side pipe 22 form a tree-like pipeline, which is placed inside the main body 1 of the storage silo. After grain is injected into the main body 1 of the storage silo, the tree-like pipeline is located within the grain. During ventilation, the fan 3 is started, and the fan 3 blows air into the built-in groove 23 of the built-in pipe 21 through the ventilation pipe 31. The air is then dispersed through the side cavity 24 and finally sprayed out from both sides of the side pipe 22 through the air guide groove 241. At the same time, the air is also sprayed out from the bottom of the side pipe 22 through the bottom groove 242. Because the side pipes 22 are distributed in different positions within the grain, they can directly inject air into the grain, thereby better ventilating the grain and improving the ventilation effect.

[0024] The air guide 241 is designed to be arc-shaped. When the grain moves in the warehouse, the arc-shaped air guide 241 makes it difficult for the grain to fall directly into the trough. Instead, the grain slides down the arc-shaped surface, which can prevent the grain from entering the air guide 241 to a certain extent.

[0025] When the blower 3 is started for ventilation, air is ejected from the bottom trough 242. At this time, the ejected airflow will form a barrier effect to a certain extent. The direction of the airflow is vertically outward, while the grain moves vertically downward under the action of gravity. The ejected airflow will prevent the grain from approaching and entering the bottom trough 242, thereby preventing the grain from clogging the bottom trough 242.
