Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, specifically a grain storage device that removes moisture by ventilating with dry, cold air. Background Technology

[0002] Grains are susceptible to environmental factors such as temperature, humidity, and air quality, which can lead to spoilage or quality deterioration. Therefore, scientific and reasonable storage methods are crucial for maintaining grain quality.

[0003] Currently, in addition to conventional grain storage technologies, refrigerated storage, controlled atmosphere storage, or vacuum storage are common storage methods. Refrigerated storage involves preserving grains in a low-temperature environment. However, grains themselves have a certain degree of activity, generating heat and moisture, especially when grains are piled up. This reduces the impact of the external environment, primarily the effects of prolonged rainy weather such as the plum rain season.

[0004] In addition to the above, multiple processes are required before grain can be stored, such as wheat. First, it needs to be harvested, then hulled and dried before being stored in the granary. These intermediate steps result in significant grain loss. With the advancement of mechanization, harvesters can perform both harvesting and hulling. If the harvested grain is directly stored in the granary for drying, the efficiency of grain storage can be greatly improved, while reducing waste.

[0005] Therefore, designing a grain storage device that can maintain low temperatures and remove moisture while also containing freshly harvested grain has become an urgent requirement. Utility Model Content

[0006] The technical problem to be solved by this utility model is: to design a grain storage device that can maintain the low temperature of stored grain and remove moisture in a timely manner.

[0007] The technical solution to the technical problem to be solved by this utility model is: a grain storage device for removing moisture by venting dry and cold air, including a silo body, an insulation layer on the outside of the silo body, and a protective shell on the outside of the insulation layer; a box-type ventilation layer at the bottom of the silo body for inputting dry and cold air into the silo body; the box-type ventilation layer is provided with a circulating air inlet, and a circulating air outlet is provided at the top of the silo body. The circulating air inlet and the circulating air outlet are connected in series by a dehumidifying air conditioner through a pipe to form circulating dry and cold air inside the silo body, or when the temperature and humidity are lower than a set threshold, natural ambient gas is directly introduced through the circulating air inlet.

[0008] Even better, the box-type ventilation layer includes a ventilation blind plate and a ventilation plate, with the ventilation blind plate located on the outside and the ventilation plate located on the inside; the ventilation plate is provided with air intake areas, and the air intake areas are staggered with air intake holes.

[0009] Even better, the air intake area has an opening and the opening is connected to the air intake grille.

[0010] Even better, the inner wall of the ventilation blind panel is equipped with an insulation layer.

[0011] Even better, a dry and cold air diffuser is installed at the bottom of the interior of the chamber, and the dry and cold air diffuser has evenly distributed air inlets.

[0012] The dry and cool air diffuser is connected to the box-type ventilation layer, or the dry and cool air diffuser is connected to the dehumidifying air conditioner.

[0013] Even better, a dry and cold air diffuser is installed at the bottom of the chamber, and the diffuser has evenly distributed air inlets; the lower part of the dry and cold air diffuser is connected to the box-type ventilation layer in the air inlet area.

[0014] Even better, the upper part of the dry, cold air diffuser is conical with the tip pointing upwards.

[0015] Even better, a grain inlet assembly is provided on the upper part of the silo body, and grain hoppers are evenly distributed on the upper part of the silo body. The grain hoppers are inclined and their upper ends are connected to the grain inlet assembly.

[0016] Even better, the thickness of the upper part of the box-type ventilation layer is less than the thickness of the lower part.

[0017] Even better, the silo body includes the silo body, the silo top, and the silo bottom. The upper part of the silo body is connected to the silo body via an upper ring beam, and the bottom of the silo body is connected to the silo bottom via a main ring beam.

[0018] The beneficial effects of this utility model are as follows:

[0019] First, by installing a dry-cool air circulation system in the grain storage device, the dehumidifying air conditioner in the system maintains a constant temperature inside the storage chamber and removes moisture. Simultaneously, a box-type ventilation layer is installed at the bottom of the storage chamber to effectively circulate dry-cool air into the interior, maintaining a constant temperature and humidity, ultimately extending the grain's shelf life.

[0020] Second, by setting up a dry and cool air circulation system, the dehumidifying air conditioner in the dry and cool air circulation system maintains a constant temperature inside the warehouse and removes moisture from the warehouse. Freshly harvested grain can be put directly into the warehouse, and the moisture is removed by dry and cool air inside the warehouse to meet the standards for grain storage. This can improve the efficiency of grain storage and reduce grain waste. Attached Figure Description

[0023] To make the technical solution and beneficial effects of this utility model clearer, the implementation methods of this utility model will be explained in further detail below.

[0024] A grain storage device for removing moisture through dry, cold air includes a silo body, comprising a silo frame, a silo top at the top of the silo frame, and a silo bottom at the bottom of the silo frame. The upper and lower parts of the silo frame are provided with an upper ring beam 401 and a main ring beam 402. The silo frame and the silo top are connected via the upper ring beam 401, and the silo bottom is connected to the silo frame via the main ring beam 402. The upper ring beam is made of steel strip, and the main ring beam is made of I-beams. The silo top has a grain inlet assembly for filling with grain, and the silo bottom has a grain outlet for discharging grain. Currently, the silo bottom and silo frame are mostly conical in shape. This invention is a method of low-temperature storage; therefore, an insulation layer is provided on the outside of the silo frame, and a protective shell is provided on the outside of the insulation layer. By providing an insulation layer, the consumption of the cold source can be reduced, thereby achieving the beneficial effect of reducing energy consumption. The protective shell is provided to protect the silo frame and the insulation layer.

[0025] like Figure 1 As shown, a box-type ventilation layer 100 for introducing dry, cool air into the silo is installed at the bottom of the silo. The box-type ventilation layer 100 is a closed space composed of an outer ventilation blind plate 101 and an inner ventilation plate 102. The ventilation blind plate 101 and ventilation plate 102 can be connected to the main ring beam to form a sealed space. The bottom of the silo is conical with the pointed end facing downwards. Correspondingly, the ventilation blind plate 101 and ventilation plate 102 are also conical, but their tapers are different to ensure that the thickness of the upper part of the box-type ventilation layer is less than that of the lower part. The ventilation blind plate 101 is a sealed plate, forming an airtight space. A circulating air inlet is located on the ventilation blind plate 101. Circulating air outlets are located at the top and top of the silo. The circulating air inlet and outlet are connected in series with a dehumidifying air conditioner via pipes. Figure 1The diagram does not show the air inlet and outlet pipes of the dehumidifying air conditioner. In actual products, the installation location of the dehumidifying air conditioner and the pipes connecting it to the chamber can be determined as needed. The dehumidifying air conditioner dehumidifies and regulates temperature while also having a certain air supply capacity, blowing dry, cool air into the chamber. To better circulate the dry, cool air, a fan can be connected in series in the piping. After the dehumidifying air conditioner is started, dry, cool air enters from the bottom, while the hot air and water vapor generated inside the chamber flow out from the top, forming a circulating dry, cool airflow through dehumidification and cooling by the dehumidifying air conditioner. During the circulation of the dry, cool air, because the upper thickness of the box-type ventilation layer 100 is less than the lower thickness, it is equivalent to the dry, cool air flowing in a pipe with gradually decreasing aperture. The lower part has a slower flow velocity and higher pressure into the chamber, while the upper part has a faster flow velocity and lower pressure. The pressure increases further down the chamber. This gas pressure design can offset the pressure at the bottom of the chamber, thus achieving a more uniform introduction of dry, cool gas into the chamber. To avoid the problem of insufficient air intake at the bottom and excessive air intake at the top under the same pressure, thus preventing damage to the grain near the bottom.

[0026] Furthermore, to achieve better insulation and reduce the energy consumption of the dehumidifying air conditioner, an insulation layer is installed on the inner wall of the ventilation blind plate 101. This insulation layer is an insulation board or sheet made of insulation material.

[0027] To achieve the requirement of both allowing dry, cool air to pass through and maintaining strength, an air intake area is provided on the ventilation plate 102. The air intake area can be set into multiple block-shaped regions, evenly distributed along the circumference. Staggered air intake holes can be formed in the air intake area. These air intake holes are micropores, with a diameter smaller than the minimum length of the grain particles. Alternatively, a large opening can be formed in the air intake area, and an air intake grid can be installed at the opening. The air intake grid has air intake holes or air intake grilles, again with the size of the air intake holes or grilles smaller than the minimum length of the grain particles.

[0028] Furthermore, to better facilitate the introduction of dry, cool air, a dry, cool air diffuser 200 is installed at the bottom of the chamber, specifically on the conical surface of the chamber bottom. The dry, cool air diffuser 200 has evenly distributed air inlets. The dry, cool air diffuser 200 is connected to the box-type ventilation layer 100, or directly to a dehumidifying air conditioner. In this case, dry, cool air can be diffused into the interior of the chamber through the dry, cool air diffuser 200 extending deep into the chamber.

[0029] Alternatively, the lower part of the dry, cool air diffuser 200 connects to the box-type ventilation layer 100 in the air intake area. In this case, the air intake area on the ventilation panel 102 is set as an opening. The opening can be open or covered by a breathable partition.

[0030] Furthermore, in order to ensure that the dry and cold air inside the dry and cold air diffuser 200 is diffused evenly, the upper part of the dry and cold air diffuser 200 is conical with the tip pointing upwards.

[0031] Even better, the upper part of the silo is evenly equipped with grain dispersing cylinders 300, which are inclined and whose upper ends are connected to the grain inlet assembly. The port of the grain inlet assembly located inside the silo coincides with the axis of the silo. By setting up grain dispersing cylinders, the grain can be dispersed around the silo, avoiding low efficiency when filling the silo due to poor grain flowability.

[0032] Even better, for the safety of inspection personnel, guardrails are installed around the top of the warehouse.

[0033] Furthermore, to facilitate inspections of the warehouse interior, manholes for entering the warehouse interior are installed on the top of the warehouse.

[0034] In summary, the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification.
