Description

Technical Field

[0001] The utility model relates to the field of storage circulation ventilation devices, in particular to a storage circulation ventilation device for grains. Background Art

[0002] Grain refers to the general term for various plant seeds used in cooking food, and can also be generally referred to as "grains". Grain crops are rich in nutrients, mainly protein, vitamins, dietary fiber, fat, starch, etc. During the storage period, grains often rot or get infested with insects due to changes in the environment, climate, ventilation and other factors. Therefore, good ventilation and heat dissipation conditions must be maintained during the storage period.

[0003] The existing circulating ventilation devices, when in use, can often only ventilate the inside of the grain channel as a whole. When faced with some narrow and humid areas, they are unable to stably ventilate and quickly dry the area, and are not very functional during use.

[0004] Therefore, it is necessary to invent a circulating ventilation device for grain storage to solve the above problems. Utility Model Content

[0026] The top of the connecting groove 11 is connected to a first air outlet pipe 14 , and the other end of the first air outlet pipe 14 is connected to a hot air box 15 , so that the gas extracted by the first fan 12 in the connecting groove 11 is transferred to the hot air box 15 through the first air outlet pipe 14 for drying and heating.

[0027] The bottom of the second ventilation slot 2 is connected to a second air inlet pipe 16, and the other end of the second air inlet pipe 16 is connected to the bottom of the hot air box 15. The air dried in the hot air box 15 and the connecting slot 11 is transferred to the second ventilation slot 2 through the second air inlet pipe 16 and discharged to the outside through the second ventilation slot 2.

[0028] The middle part of the second air inlet pipe 16 is connected to a solenoid valve 17 , and the air flow of the second air inlet pipe 16 is controlled by the solenoid valve 17 . When the solenoid valve 17 is closed, the air cannot pass through the second air inlet pipe 16 .

[0029] An electric heating pipe 18 is arranged on the right side of the inner cavity of the hot air box 15. A power supply 19 is bolted to the right side of the hot air box 15, and the left side of the power supply 19 is connected to the right side of the electric heating pipe 18. The amount of heat emitted by the electric heating pipe 18 is controlled by controlling the amount of power provided by the power supply 19 to the electric heating pipe 18.

[0030] A desiccant 20 is arranged on the inner side of the pull-out mesh frame 13, and a second fan 21 is bolted to the inner side of the second ventilation slot 2. When the humid air in the warehouse is drawn out by the first ventilation slot 1 and enters the pull-out mesh frame 13, the air will first pass through the desiccant 20, and then the air will be preliminarily dried. The second fan 21 can draw out the air output from the second air inlet pipe 16 and discharge it through the second ventilation slot 2.

[0031] The four corners of the first ventilation slot 1 and the second ventilation slot 2 are bolted with a transverse plate 24, and the inner side of the transverse plate 24 is threadedly connected with bolts 22. The transverse plate 24 and the bolts 22 facilitate the user to install and quickly fix the first ventilation slot 1 and the second ventilation slot 2.

[0032] The inner side of the blades 5 is provided with a slide groove 23, and the inner side of the slide groove 23 is slidably connected to the surface of the connecting rod 6, so that during the vertical movement of the connecting rod 6, the slide groove 23 drives the blades 5 to rotate with the cross bar 4 as the axis.

[0033] Refer to the instruction manual Figure 1-5Working principle: through the installation plate 3, cross bar 4, blade 5, connecting rod 6, vertical rod 7, servo motor 8, disc 9, connecting rod 10 and other components, during the use of the device, when there is a humid environment problem somewhere in the grain storage, only the first ventilation slot 1 and the second ventilation slot 2 need to be installed in sequence, and then the first fan 12 is started according to the relative humidity in the environment. The first fan 12 first draws the air in the warehouse into the connecting slot 11, and the desiccant 20 in the pull-out mesh frame 13 in the connecting slot 11 will preliminarily dry the air entering the interior. After the desiccant 20 has been used for a long time, the pull-out mesh frame 13 can be slid out from the inner side of the connecting slot 11, and the desiccant 20 inside it can be replaced, and then the solenoid valve 17 is opened, and the second fan 21 and the power supply 19 are turned on to make the electric heating tube 18 pass through The air in the hot air box 15 is heated and dried twice, and finally the dry air is discharged from the second ventilation slot 2 to complete a cycle. The user can control the opening and closing of the servo motor 8. When the ventilation device needs to run at full power, the servo motor 8 drives the disc 9 to rotate. During the rotation of the disc 9, the vertical rod 7 is driven to move vertically through the connecting rod 10. During the vertical movement of the vertical rod 7, the connecting rod 6 is driven to slide on the inner side of the slide slot 23, and the blades 5 are driven to rotate through the slide slot 23. When all the blades 5 rotate to a state close to the horizontal state, the first ventilation slot 1 is fully opened. Otherwise, the blades 5 will gradually close, thereby reducing the size of the air intake in the first ventilation slot 1, thereby reducing the operating efficiency of the overall ventilation device, which is convenient for the user to stably dry the air entering and leaving the warehouse through the first ventilation slot 1 to avoid the entry of humid air into the granary.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
