Technical Field

[0001] The utility model relates to a barn cooling system. Background Art

[0002] In the grain storage industry, especially in the process of grain storage, it is crucial to control the temperature and humidity of the storage environment. Traditional barn cooling systems usually rely on natural ventilation or simple mechanical ventilation to reduce the temperature in the warehouse.

[0003] Traditional cooling systems often have the problem of low energy utilization efficiency because they fail to effectively recycle the cooling air, resulting in a large amount of cooling energy waste, which not only increases energy consumption but also increases operating costs. At the same time, the cooling effect of these systems is often uneven, and it cannot be guaranteed that the grain in every corner of the warehouse can be effectively cooled, which in turn affects the long-term storage quality of the grain. In view of this, the utility model proposes a barn cooling system to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figure 1-3 As shown, this embodiment proposes a barn cooling system, including a barn cooler 20, for performing a cooling process on a plurality of groups of barns 10;

[0026] The grain cooler 20 is provided with an air outlet duct 21, and a plurality of groups of air supply ducts 211 are provided on the air outlet duct 21, and the plurality of groups of air supply ducts 211 are connected to a plurality of groups of barns 10. The grain cooler 20 is provided with an air inlet duct 22, and a plurality of groups of return air ducts 221 are provided on the air inlet duct 22, and the plurality of groups of return air ducts 221 are connected to a plurality of groups of barns 10. The air outlet duct 21 outputs cooling fluid into the plurality of groups of barns 10, and the air inlet duct 22 inputs cooling fluid in the plurality of groups of barns 10 into the grain cooler 20.

[0027] In this case, fans are provided in both the air inlet duct 22 and the air outlet duct 21. The fan in the air outlet duct 21 is used to drive the cooling fluid into the barn 10, and the fan in the air inlet duct 22 is used to drive the air in the barn 10 into the grain cooler 20.

[0028] In this embodiment, when cooling multiple groups of barns 10, the multiple groups of barns 10 are respectively connected to multiple groups of air supply ducts 211, and then the multiple groups of air supply ducts 211 are connected to the air outlet ducts 21, and at the same time, the multiple groups of barns 10 are respectively connected to multiple groups of return air ducts 221, and then the multiple groups of return air ducts 221 are connected to the air inlet ducts 22. The operation of the grain cooler 20 generates a flowing cooling fluid, and then the cooling fluid enters the air supply duct 211 through the air outlet duct 21, and then enters the multiple groups of barns 10. After the temperature in the barn 10 is reduced, the air in the barn 10 is guided to the return air duct 221 under the action of the grain cooler 20, and the air in the barn 10 is guided back to the grain cooler 20 by the air inlet duct 22 for re-cooling.

[0029] By setting up the air outlet duct 21 and the air inlet duct 22, as well as multiple groups of supply air ducts 211 and return air ducts 221 connected thereto, an efficient air circulation system is formed. The system can transport the cooling fluid generated by the grain cooler 20 to multiple groups of barns 10 through the supply air duct 211, thereby achieving effective cooling inside the barn 10. Subsequently, the air in the barn 10 is led back to the grain cooler 20 through the return air duct 221 for further cooling, thereby forming a closed-loop cooling cycle. This design not only improves the cooling efficiency and reduces energy consumption, but also reduces operating costs by recycling the cooling fluid, thereby improving the overall economy and environmental friendliness of the system.

[0030] Specifically, a first connecting pipe 212 is provided between the air supply pipe 211 and the barn 10 , and a first electric ball valve 213 is provided on the first connecting pipe 212 .

[0031] Specifically, a second connecting pipe 222 is provided between the return air pipe 221 and the barn 10 , and a second electric ball valve 223 is provided on the second connecting pipe 222 .

[0032] In this embodiment, the first electric ball valve 213 and the second electric ball valve 223 can be set to facilitate the control of the opening and closing of the first connecting pipe 212 and the second connecting pipe 222, thereby controlling whether the cooling fluid enters the corresponding barn 10, so as to facilitate individual control of whether to cool according to the situation in the barn 10.

[0033] Specifically, a monitor 30 is provided in the barn 10, and a PLC control system is provided in the grain cooler 20. The monitor 30, the first electric ball valve 213, and the second electric ball valve 223 are all connected to the PLC control system.

[0034] In this embodiment, the monitor 30 is a temperature sensor and a humidity sensor, which are used to monitor the real-time environmental conditions in each barn 10. The data of these sensors are fed back to the PLC control system to ensure that each barn 10 can be maintained within the set temperature range;

[0035] Of course, according to the feedback from the monitor 30 , the PLC control system controls the corresponding first electric ball valve 213 and second electric ball valve 223 to open or close, so as to perform the refrigeration process according to the actual situation of the barn 10 .

[0036] Specifically, two groups of installation pipes 40 are provided in the barn 10 , and the two groups of installation pipes 40 are connected to the first connecting pipe 212 and the second connecting pipe 222 , respectively.

[0037] Specifically, the installation pipeline 40 includes a vertical pipeline 42, and horizontal pipelines 44 are arranged at both ends of the vertical pipeline 42;

[0038] Multiple groups of penetrating air outlet holes 43 are evenly arranged on the outer walls of the vertical duct 42 and the horizontal duct 44 .

[0039] Specifically, the two groups of vertical pipes 42 are in contact with the bottom and the top of the inner cavity of the barn 10 respectively, so that the vertical pipes 42 are vertically arranged in the inner cavity of the barn 10.

[0040] Specifically, flanges 41 are provided on both groups of the horizontal pipes 44 , and a sealing plate 45 is provided on one group of the flanges 41 .

[0041] In this case, the air outlets 43 are all disposed inside the barn 10;

[0042] In this embodiment, when the return air duct 221 and the supply air duct 211 are connected to the barn 10, the supply air duct 211 is connected to a set of installation ducts 40, that is, the first connecting duct 212 on the supply air duct 211 is connected to the bottom horizontal duct 44, and the top horizontal duct 44 is sealed by a sealing plate 45, so that the cooling fluid is transported from bottom to top to the inside of the barn 10;

[0043] The return air duct 221 is connected to another set of installation ducts 40 in the same barn 10, that is, the second connecting duct 222 on the return air duct 221 is connected to the top horizontal duct 44, and the bottom horizontal duct 44 is sealed by a sealing plate 45, so that the air in the barn 10 is input into the grain return cooler 20 from bottom to top;

[0044] During the cooling process, the cooling fluid enters the first connecting pipe 212 through the air supply pipe 211 and flows from the bottom horizontal pipe 44 to the top horizontal pipe 44. During the flow, the cooling fluid can fully contact the grains in the barn 10 through the vertical pipe 42.

[0045] When recycling the air in the grain bin 10, the horizontal pipe 44 at the top can directly recycle the air on the surface of the grain, and the vertical pipe 42 extending into the grain can recycle the air inside the grain;

[0046] Through the above cooling path, the cooling fluid can completely pass through the grain layer from bottom to top. This upward flow design ensures that the cooling fluid is fully in contact with the grain, thereby achieving more uniform and efficient cooling, while also promoting the efficiency of air circulation.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
