Description

Technical Field

[0001] The utility model relates to a granary, in particular to a granary with a ventilation system. Background Art

[0002] The storage of grain and other agricultural products requires a relatively low temperature environment. Grain storage is typically done in loose piles, resulting in high grain pile heights and large warehouse areas, which can easily lead to higher temperatures at the center of the pile. Existing warehouses often use fans or air conditioners for cooling. However, the air conditioner outlets are located above the grain pile, so the cold air accumulates at the top of the pile and has difficulty reaching the bottom center of the pile, resulting in ineffective cooling at the bottom and center of the pile.

[0003] The refrigeration equipment includes a water-cooled chiller. The Chinese patent with application number 2023101112893 disclosed a water-cooled chiller on February 14, 2023, including a device body, the device body including a placement base, the top of the placement base is equipped with a chiller body, the top of the placement base is fixedly equipped with a control cabinet through a mounting bracket, the chiller body includes an evaporator body and a condenser body, the end of the chiller body is connected to a cooling delivery pipe, one end of the cooling delivery pipe is fixedly connected to a cooling heat dissipation pipe, and the cooling heat dissipation pipe is connected to the chiller body through a connecting pipe, and the device body also includes a water cooling unit. The water-cooling unit includes a water-cooling main box, which is fixedly installed on the outside of the cooling and heat dissipation pipe through a mounting frame. A water-cooling storage box is fixedly installed on the top of the water-cooling main box, and the top of the water-cooling storage box is connected to a water inlet channel. The bottom end of the water-cooling storage box is connected to a first connecting pipe, and the first connecting pipe is connected to the interior of the water-cooling main box. A recovery water tank is installed at the bottom end of the water-cooling main box, and a second connecting pipe is fixedly installed on the top of the recovery water tank, and the second connecting pipe is connected to the interior of the water-cooling main box. The bottom end of the interior of the recovery water tank is connected to a recovery interface. A water pump body is provided inside the water-cooling storage box, and the end of the recovery interface is connected to a return pipe, and the end of the return pipe is connected to the water pump body.

[0004] Chinese patent application number 2023224618091 disclosed a water-cooling machine on September 11, 2023, which includes a frame, a water tank, and a refrigeration system with an evaporator. The frame is provided with a water inlet interface and a water outlet interface. A water outlet pipeline is provided between the water tank and the water outlet interface. A pump body is provided on the water outlet pipeline to pump water in the water tank to the water outlet interface. The water in the water outlet pipeline is connected to the water tank, and the water outlet pipeline passes through the evaporator. After being cooled by the evaporator, the water in the water outlet pipeline is directly transported to the outside through the water outlet interface to reduce the influence of the water temperature in the water tank on the cooling effect, avoid the situation where there is no time for cooling, and facilitate the water-cooling machine to cool the nozzle more stably. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a grain storehouse with a ventilation system.

[0006] The utility model solves the technical problem by adopting a technical solution: a grain warehouse with a ventilation system, including walls surrounding it on four sides and a roof, wherein the ventilation system includes:

[0007] A refrigeration device for providing cold air to the grain depot;

[0008] A ground trough is opened on the ground inside the wall, and the trough opening is covered with a grain blocking plate, and the grain blocking plate is provided with ventilation holes that prevent grain from passing through;

[0009] An air guide member located on the inner surface of the wall is a tubular structure with a ventilation cavity. An upper air inlet connected to the internal ventilation cavity is provided at the upper portion of the air guide member, and a lower air outlet connected to the floor trough is provided at the lower portion of the air guide member. An openable and closable upper sealed door is installed at the upper air inlet;

[0010] An exhaust fan is installed in the ventilation cavity of the air guide and is used to draw air in the grain storage into the ventilation cavity through the upper air inlet.

[0011] The beneficial effects of the utility model are as follows: cold air is released into the grain depot through the refrigeration device to reduce the temperature, and then the upper sealed door is opened, and the exhaust fan is started to suck the cold air in the grain depot into the ventilation cavity, and the cold air is transported to the ground trough through the ventilation cavity. Since the ground trough is arranged at the bottom of the grain depot, the cold air can be transported to different areas at the bottom of the grain pile through the ground trough. The cold air cools the temperature of the bottom, middle and top of the grain pile through the air holes on the grain retaining plate, so that the temperature therein is always maintained below 9 degrees, thereby ensuring the safety of reserves.

[0012] The system is further configured such that an external air inlet connected to the air guide is formed on the wall, and an openable and closable external sealed door is installed at the external air inlet. The exhaust fan can be used to draw air from outside the grain storage into the ventilation cavity through the external air inlet. In winter, when the temperature outside the grain storage is lower than the temperature inside the grain storage, the external sealed door can be opened and the exhaust fan activated to draw the low-temperature external air into the grain storage. The air is then cooled from the bottom up through the ground trough, thereby ensuring a cooling effect and saving energy and electricity.

[0013] The air guide is further configured such that the air guide is positioned proximate to the inner surface of the wall, the ground troughs include a first ground trough along the inner edge of the wall, and a plurality of second ground troughs perpendicular to the first ground troughs, wherein the air outlet at the lower portion of the air guide is connected to the first ground troughs. The provision of the first and second ground troughs ensures sufficient cooling of the bottom of the grain pile.

[0014] The upper surface of the grain retaining plate is a raised structure, and the ventilation holes are evenly distributed on the surface of the grain retaining plate. The raised structure can increase the surface area, thereby increasing the density of the ventilation holes and further increasing the amount of cold air released.

[0015] The wall is further configured such that a through hole is formed in the upper portion thereof, and the refrigeration device is an air conditioner having an outdoor unit and an indoor unit, wherein the outdoor unit is installed outside the granary and the indoor unit is installed inside the granary, and the outdoor unit and the indoor unit are connected by a connecting pipe extending through the granary, and the outer diameter of the connecting pipe is adapted to the inner diameter of the through hole. The refrigeration device can be a conventional air conditioner, which is relatively easy to obtain and requires relatively little modification.

[0016] The device further comprises an upper through-hole and a lower through-hole located below the upper through-hole in the upper portion of the wall. The refrigeration device is a water-cooled chiller. A cold water pipe is connected to the water outlet of the water-cooled chiller. The cold water pipe passes through the upper through-hole into the grain storage and exits through the lower through-hole to connect to the water inlet of the water-cooled chiller. A fan is also installed in the grain storage, the fan facing the cold water pipe. To improve the cooling effect, a water-cooled chiller with a lower cooling temperature is used, thereby ensuring that the temperature inside the grain storage is closer to 9 degrees Celsius.

[0017] The wall is further configured with a plurality of ventilation openings on the upper portion, each of which is equipped with a ventilation fan inside and an openable and closable auxiliary sealing door outside. Similarly, in winter, when the temperature outside the grain storage is lower than the temperature inside, the auxiliary sealing door can be opened and the ventilation fan activated to draw cooler air from outside into the grain storage, effectively lowering the temperature above the grain storage. This not only ensures a cooling effect but also saves energy and electricity.

[0018] It is further configured that: the air guide is a box-type structure, and the ventilation cavity is installed in the box-type structure. The box-type structure can ensure that it has good pressure resistance and avoids deformation or collapse caused by external pressure.

[0019] The exhaust fan is further configured to be installed at the lower air outlet, with the air intake direction of the exhaust fan being away from the opening of the lower air outlet, and the air discharge direction of the exhaust fan being toward the opening of the lower air outlet. The installation position of the exhaust fan ensures that when sucking air, it can absorb air from both the upper air inlet and the outer air inlet, thus achieving dual purpose.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] Example 1: Figures 1 to 6As shown, this embodiment includes a surrounding wall 1, a roof 2, and a ventilation system. The ventilation system includes a water-cooled chiller 3 for cooling the granary. A ground trough 4 is provided on the ground within the wall 1. The opening of the ground trough 4 is covered with an upwardly raised grain retaining plate 43. The grain retaining plate 43 has ventilation holes 44 that prevent grain from passing through. A box-like air guide 5 is installed on the inner wall of the granary. The air guide 5 is composed of a frame and a panel surrounding the frame. The air guide 5 has a ventilation cavity within it. The upper portion of the air guide 5 has an upper air inlet 51 connected to the internal ventilation cavity. The lower portion of the air guide 5 has a lower air outlet 52 connected to the ground trough 4. An openable and closable upper sealing door 511 is installed at the upper air inlet 51. An exhaust fan 53 is also installed in the ventilation cavity of the air guide 5 to draw air from the granary into the ventilation cavity. At the same time, an external air inlet 54 connected to the air guide 5 is opened on the outer wall of the wall 1. The external air inlet 54 is equipped with an openable and closable external sealing door 541. In winter, when the upper air inlet 51 is closed and the external sealing door 541 is opened, the exhaust fan 53 draws the air outside the grain storage into the ventilation cavity through the external air inlet 54. The inhaled cold air is then transported to various locations in the grain storage through the ground trough 4. The exhaust fan 53 is installed at the lower air outlet 52. The air inlet direction of the exhaust fan 53 is away from the opening of the lower air outlet 52, and the air outlet direction of the exhaust fan 53 is facing the opening of the lower air outlet 52. This installation position ensures that when sucking air, it can absorb air from both the upper air inlet 51 and the external air inlet 54, achieving dual purposes. The ground trough 4 includes a first ground trough 41 arranged along the inner edge of the wall 1 and a plurality of second ground troughs 42 arranged perpendicular to the first ground trough 41. The lower air outlet of the air guide 5 is connected to the first ground trough 41. The above-mentioned sealed doors (511, 541) can be electrically controlled electric window sashes, that is, the window frame is installed on the periphery of the opening, and the window sash is the sealed door. The electric window sash does not require manual intervention when in use, and is more simple to operate. The flow of cold air can be controlled more timely, thereby ensuring timely cooling of the temperature in the grain warehouse.

[0030] In this embodiment, Figure 8 As shown, the upper portion of the wall 1 is provided with an upper through-hole 11 and a lower through-hole 12 located below the upper through-hole 11. A cold water pipe 31 is connected to the water outlet of the water-cooled chiller 3. This cold water pipe 31 passes through the upper through-hole 11, enters the grain storage, and exits through the lower through-hole 12, where it is connected to the water inlet of the water-cooled chiller 3. A fan 16 is also installed within the grain storage, facing the portion of the cold water pipe 31 within the grain storage. To further enhance the cooling effect within the grain storage, the cold water pipe 31 can be arranged along the inner wall of the grain storage wall, thereby accelerating the temperature drop within the grain storage. Furthermore, the upper portion of the wall 1 is provided with several ventilation openings 13. Ventilation fans 15 are installed inside these openings 13, and openable and closable auxiliary sealing doors 14 are installed outside these openings 13. The auxiliary sealing doors 14 can also be electrically controlled, electric sashes.

[0031] In this embodiment, Figure 7 The arrow in the middle is the path of the airflow, so Figure 7 The installation position of the exhaust fan 53 can be clearly seen, and the space corresponding to the air inlet of the exhaust fan 53 is the upper air inlet 51 and the outer air inlet 54 in the ventilation cavity are in the same space. Therefore, when the exhaust fan 53 is working, it can absorb the air at the upper air inlet 51 and the outer air inlet 54 at the same time, thereby meeting the cooling needs under different temperature environments.

[0032] Example 2: This example differs from Example 1 primarily in the refrigeration device in the ventilation system. In this example, only a single through-hole is required in the upper portion of wall 1. The refrigeration device utilizes a conventional air conditioner, comprising an outdoor unit and an indoor unit. The outdoor unit is mounted outside the granary, while the indoor unit is mounted inside the granary. The outdoor and indoor units are connected via a connecting pipe extending through the granary, with the outer diameter of the connecting pipe matching the inner diameter of the through-hole. Because the structures of the indoor and outdoor units are relatively simple and are conventional, their specific installation methods are conventional for those skilled in the art. Therefore, they are not illustrated and detailed in this application, and do not affect the full disclosure of this application.
