Technical Field
[0001] This application relates to the technical field of grain storage ventilation equipment, and particularly to an intelligent ventilation equipment for grain storage. Background Art
[0002] Grain storage, that is, the storage of grain, mainly uses grain bins. When grains are piled up in a grain bin, they are very likely to get stuffy and sprout or rot. Therefore, a ventilation system needs to be set up in the grain bin. Most traditional ventilation systems are to open air vents on the grain bin wall and set up blowers. The blowers blow air into the grain bin to blow away the humid and hot air in the grain bin, or suck out the hot air in the grain bin. This method has a good effect on cooling and dehumidifying the surface layer of grains, but it cannot meet the heat dissipation requirements for the lower layer.
[0003] Therefore, this application provides an intelligent ventilation equipment for grain storage to improve the heat dissipation and dehumidification effects on the lower-layer accumulated grains. Utility Model Content

The side wall of the shunt pipe 4 is spacedly connected with a plurality of charging pipes 5. A guide pipe 6 is connected to the side wall of the air duct 3. The end of the guide pipe 6 extends into the inner top of the granary 1 and is connected to a flexible telescopic pipe 7. The end of the telescopic pipe 7 is connected to a conical barrel 8. A plurality of air holes are evenly distributed on the side walls of the conical barrel 8 and the charging pipes 5.
[0025] Details of the principle of this example:
[0026] An intelligent ventilation device for grain storage includes an air outlet 12, an air inlet, a temperature sensor 10, and a humidity sensor 11.
[0027] The air outlet 12 is arranged at the top of the granary 1 and is provided with a waterproof top cover to prevent rainwater from seeping in. It is also provided with a filter screen cover 9 to prevent foreign objects and birds from entering the granary 1 along the air outlet 12 and polluting / stealing the grain.
[0028] The air inlet is arranged at a position near the bottom of the side of the granary 1 wall. An air duct 3 is inserted into the air inlet. One end of the air duct 3 outside the granary 1 is connected to a blower 2. The blower 2 is fixedly installed on a bracket outside the granary 1 through fasteners. A dehumidification box, such as an activated carbon box, is provided at the air inlet of the blower 2 to filter the moisture in the outside air so as not to inject humid air into the granary 1. One end of the air duct 3 inside the granary 1 is connected to a shunt pipe 4. The shunt pipe 4 is arranged along the skirting board part of the inner wall of the granary 1. The side wall of the shunt pipe 4 is spacedly connected with a plurality of charging pipes 5. The charging pipes 5 extend vertically to the shunt pipe 4 and extend into the granary 1. And a guide pipe 6 is also connected to the side wall of the part of the air duct 3 outside the granary 1 through an electric valve. The other end of the guide pipe 6 extends into the granary 1 from the upper end of the granary 1 wall and is close to the roof of the granary 1. One end of the guide pipe 6 extending into the granary 1 is connected to a flexible telescopic pipe 7. The end of the telescopic pipe 7 is connected to a conical barrel 8. A lifting handle is provided on the upper side wall of the conical barrel 8. A plurality of air holes are evenly distributed on the side walls of the conical barrel 8 and the plurality of charging pipes 5.
[0029] The temperature sensor 10 is an ultraviolet sensor. There are multiple of them, which are evenly distributed on the inner wall of the granary 1 and suspended in the middle of the granary 1, showing a scattered distribution, so as to comprehensively control the temperature data of each corner in the granary 1.
[0030] The humidity sensor 11 has multiple ones, which are evenly distributed on the inner wall of the granary 1 and suspended in the middle of the granary 1, showing a scattered distribution, so as to comprehensively control the humidity data of each corner in the granary 1.
[0031] According to the above technical solution:
[0032] During dehumidification and heat dissipation, the blower 2 sucks outside air into the air duct 3, and then follows the air duct 3 and the shunt pipe 4 into each inflatable pipe 5, and finally sprays out from the air holes of the air guide pipe 6. The gas is injected from the bottom layer of the piled-up grains and floats along the gaps between the grains, thereby taking away the heat temperature and humid gas of the lower-layer grains and discharging them to the outside air from the exhaust port 12, so as to achieve the purpose of dehumidifying and dissipating heat of the grains in the granary 1.
[0033] And in this process, the temperature and humidity of each corner in the granary 1 are monitored in real time through the temperature sensor 10 and the humidity sensor 11. When the temperature and humidity are too high, a signal is sent to the blower 2, and the blower 2 can appropriately increase the operating power, speed up the air blowing into the granary 1, increase the injection volume and flow rate of dry air, so as to accelerate the discharge and discharge volume of the hot and humid air, and achieve real-time control of the heat dissipation power regulation.
[0034] When the temperature sensor 10 and the humidity sensor 11 detect that the temperature and humidity inside the local grains are too high, the cone barrel 8 can also be held, pulled to the upper part of this area, and inserted. Then the electric valve is opened, and the outside dry air enters the cone barrel 8 along the air guide pipe 6 and sprays out from the air holes of the cone barrel 8 to this area, so as to dissipate heat and dehumidify the local grains. In this way, the temperature and humidity of the grains in each area of the granary 1 can be accurately controlled.
[0035] Embodiment 2, in a further embodiment of the present solution, the tip of the cone barrel 8 is provided with a leakage hole. The leakage hole is larger than the size of the grain particles and is used for pouring out the grains that have penetrated into the inside of the cone barrel 8 after the cone barrel 8 is pulled out from the grains.
[0036] Embodiment 3, in a further embodiment of the present solution, an electric heating component is provided in the air pipe. Such as an electric heating plate and an electric heating wire. When the humidity in the granary 1 is too high and the grains are prone to germinate when piled up, the electric heating component is started at this time to heat the gas injected into the granary 1, and the hot air is injected into the grains to achieve the effect of drying the air duct and improve the dehumidification effect. When the humidity is lower than the preset value, the electric heating component is turned off to prevent continuous heating and continuous temperature rise of the grains, which may damage the grains.
[0037] Embodiment 4, in a further embodiment of the present solution, a filter screen is provided at the air inlet of the blower 2. It is used to filter impurities in the sucked air to avoid grain contamination.
[0038] Embodiment 5, in a further embodiment of the present solution, there are multiple exhaust ports 12. Accelerate the discharge of the hot and humid air in the granary 1, and cooperate with the blower 2 to improve the heat dissipation and dehumidification effect.
[0039] Embodiment 6. In a further embodiment of the present solution, an exhaust fan is provided in some of the exhaust vents 12, and a non-powered ventilation cap is provided in the remaining exhaust vents 12. When the humidity and heat in the granary 1 exceed the standard, the exhaust fan can be turned on to accelerate the outward discharge of the humid and hot air, improve the air circulation speed in the granary 1, and thus improve the dehumidification and heat dissipation efficiency.
[0040] Embodiment 7. In a further embodiment of the present solution, a mesh cover 9 is provided outside each of the charging pipes 5. The mesh cover 9 is provided with fine mesh holes, and the mesh holes are smaller than the size of the grain particles. The area near the charging pipe 5 is isolated through the mesh holes to provide a preliminary space for air to be filled, and to prevent the air holes on the charging pipe 5 from being squeezed by the grains and affecting the air injection effect.

Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and the application concept of the present application, makes equivalent substitutions or changes, and should be covered within the protection scope of the present application.
