Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, and more specifically, to a grain storage ventilation, refrigeration and constant temperature system. Background Art

[0002] Grain storage is very important. In the grain storage process, temperature is an important factor affecting grain storage. Experiments have shown that low temperature of grain has the effect of inhibiting grain respiration. Below 10-15℃, grain respiration stays at a low limit level. Granaries are buildings or facilities used to store grain. Their design and structure are intended to protect grain from the influence of the external environment and ensure the safe storage and quality of grain.

[0003] After searching, a Chinese patent with application number CN202022114393.2 discloses a stratified ventilation system for granaries. In view of the problem that some of the existing simple granaries simply use exhaust fans for ventilation, and tall bungalows use ground cages and ground trough ventilation systems, and the ventilation effect is not good enough, a storage chamber is formed by setting limit blocks, partitions, baffles and the inner wall of the silo. Grain enters the silo from the feed port, and the grain falls into layers by adjusting the position of the baffles and the through holes, and ventilation is carried out through ventilation windows. The system is simple to operate, easy to install, and flexible to use. The impeller blades and scrapers are used to turn the grain so that the grain is evenly ventilated, thereby avoiding moisture accumulation in deep grain, improving the quality of grain storage, and avoiding quality degradation caused by grain squeezing.

[0004] However, during the use of the granary ventilation system, the temperature inside the granary is prone to significant changes due to external influences. The repeated changes in the granary temperature can easily cause the grain to mold and deteriorate. Therefore, a granary ventilation, refrigeration and constant temperature system is proposed.

[0010] Preferably, the number of the heat exchange plates is set to be multiple, one end of each of the multiple heat exchange plates sequentially penetrates the water collecting tank, the granary body and the heat exchange box and extends to the inside of the heat exchange box, and the heat exchange plates are set to be made of aluminum alloy.

[0013] Preferably, the number of the air outlet pipes is set to be multiple, and the tops of the multiple air outlet pipes all penetrate the hollow plate and extend to the inside of the hollow plate.

[0014] Technical effects and advantages of the utility model:

[0015] By setting up a constant temperature mechanism, rainwater is collected and stored in a water collection tank through a water collection tank and connecting water pipes. At the same time, water can be supplemented through a water supply pipe, making full use of natural resources and reducing water resource consumption. Water is used for heat exchange and cooling, and a temperature sensor is used to monitor the internal temperature of the granary in real time. When the temperature exceeds the standard, ventilation and heat exchange can be carried out in time to ensure the quality and safety of grain. The heat exchange process between the heat exchange plate and the water in the water collection tank effectively reduces the air temperature, realizing intelligent temperature control, ensuring that the interior of the granary remains low and the temperature is always in a constant state, which is conducive to the long-term storage of grain in the granary, avoiding repeated changes in the internal temperature of the granary, and avoiding excessively high temperatures in the granary that cause the grain to mold and rot;

[0016] The isolation baffle design in the heat exchange box prolongs the air residence time, making it easier for the air to achieve effective heat exchange and improve the cooling effect of the air. Through multiple air outlet pipes, the formed cold air can be evenly discharged into the granary. At the same time, the cold air enters the granary body and squeezes the hot air above it to be discharged through the ventilation pipe, thereby improving the ventilation and heat dissipation effects. At the same time, the insulation board is used for insulation, so that the internal temperature of the granary body can be more easily maintained constant, reducing energy consumption.

[0027] As attached Figure 1 , 2 As shown in 4, a fixing plate 15 is fixedly connected between the hollow plate 11 and the inner wall of the granary body 1, and the cross-sectional shapes of the connecting air duct 12 and the air inlet duct 10 are both set to be L-shaped. The bottoms of the connecting air duct 12 and the air inlet duct 10 both pass through the heat exchange box 6 and extend to the inside of the heat exchange box 6 to facilitate air circulation.

[0028] As attached Figure 1 , 2 As shown in 4, a ventilation pipe 16 is fixedly connected to one side of the granary body 1, and an electromagnetic valve 17 is installed inside the ventilation pipe 16. The electromagnetic valve 17, the temperature sensor 14 and the exhaust fan 9 are all electrically connected to the PLC controller 18, so that the electromagnetic valve 17 and the exhaust fan 9 can be controlled by the PLC controller 18, so that the PLC controller 18 can perform temperature control.

[0029] As attached Figure 5 , 6As shown, the number of heat exchange plates 7 is set to be multiple, and one end of the multiple heat exchange plates 7 passes through the water collecting tank 4, the granary body 1 and the heat exchange box 6 in sequence and extends to the inside of the heat exchange box 6. The heat exchange plates 7 are set to be made of aluminum alloy to ensure the heat exchange effect between the water in the water collecting tank 4 and the air in the heat exchange box 6.

[0030] As attached Figure 1-5 As shown, a water supply pipe 21 is fixedly connected to the top of the water collecting box 4, and a filter net 20 is fixedly installed on one side of the inner wall of the water collecting tank 3.

At the same time, heat is exchanged with the water inside the water collecting box 4 through the heat exchange plate 7, so that the heat exchange plate 7 takes away the heat of the circulating air inside the heat exchange box 6, thereby completing the heat exchange to form cold air, and the cold air enters the hollow plate 11 through the connecting air duct 12, and is discharged into the interior of the granary body 1 through multiple air outlet pipes 13, so as to complete the ventilation and constant temperature effect of the granary body 1, and at the same time, the electromagnetic valve 17 is opened, so that the hot air flow on the top of the granary body 1 is squeezed by the cold air flow and discharged through the ventilation pipe 16. After the temperature drops to the limited value, the electromagnetic valve 17 is closed by the PLC controller 18 and the exhaust fan 9 is stopped at the same time, so that the interior of the granary body 1 always maintains a constant temperature to avoid the internal temperature of the granary body 1 being too high and causing the grain to be heated and moldy.
