Description

Technical Field

[0001] This utility model relates to the field of potato storage technology, specifically a ventilation system for a potato storage warehouse. Background Technology

[0002] Potatoes are a highly nutritious food and an important staple food in some regions. Storing potatoes in warehouses can extend their shelf life. Warehouses are generally large and sealed during storage, resulting in poor gas circulation, which is not conducive to potato storage. Modern warehouses are equipped with ventilation systems to control the air circulation inside and outside the warehouse, improving the storage effect of potatoes. However, there are still some problems with the use of ventilation systems.

[0003] During operation, the ventilation system in potato storage warehouses typically has a fixed internal ventilation height. Due to the large space and overall height of the warehouse, the ventilation range is relatively limited, resulting in poor air circulation at the lower part of the warehouse. Furthermore, potato storage requires a relatively dry environment. During the rainy season, when the ventilation system is in operation, the humidity of the external environment is high, and the exchange of air between the inside and outside increases the humidity inside the warehouse, which is detrimental to potato storage.

[0004] Therefore, a ventilation system for potato storage warehouses needs to be designed to address the above issues. Utility Model Content

[0005] The purpose of this invention is to provide a ventilation system for potato storage warehouses, addressing the problem mentioned in the background art that the internal ventilation positions of potato storage warehouse ventilation systems are generally fixed-height structures. Due to the large space and overall height of the warehouse, the ventilation range during air exchange is relatively limited, resulting in poor air circulation at the lower end of the warehouse. Furthermore, potato storage requires a relatively dry environment, and during the rainy season, the humidity of the external environment is high when the ventilation system is in operation. The exchange and flow of internal and external gases leads to an increase in the humidity inside the warehouse, which is detrimental to potato storage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilation system for a potato storage warehouse, the ventilation system mainly consists of an outdoor ventilator, a main duct, a branch pipe, a regulating pipe and an indoor ventilator, and the main duct is connected to the side of the outdoor ventilator, and three branch pipes are fixed at equal intervals on the outer side of the main duct;

[0007] The lower end of the diversion pipe is connected to an regulating pipe, and an indoor ventilator is fixedly installed at the lower end of the regulating pipe. A ventilation grille is provided on the front side of the indoor ventilator.

[0008] A ventilation system for a potato storage warehouse includes:

[0009] A fixed rod is welded and fixed to the outer side of the indoor ventilator, and the side of the indoor ventilator is rotatably mounted with fan blades. The indoor ventilator and the diversion pipe are connected to each other by an automatic lifting rod.

[0010] The bottom rotating shaft is rotatably installed inside the indoor ventilator, and the interior of the indoor ventilator is interconnected with the interior of the regulating pipe. The top rotating shaft is rotatably installed inside the regulating pipe, and a transmission disc is fixedly installed on the outside of the top rotating shaft and the bottom rotating shaft. A transmission belt is installed on the outside of the transmission disc. Side gears are symmetrically fixed on the left and right sides of the top rotating shaft.

[0011] The mounting plate is fixedly disposed inside the shunt tube, and a toothed rack is fitted and fixed on the inner side of the mounting plate.

[0012] Preferably, the outdoor ventilator includes a drive chamber, a drying chamber, and an air supply chamber, and the interiors of the drive chamber, the drying chamber, and the air supply chamber are interconnected, and the interconnected structure facilitates the flow of gas between the inside and outside of the warehouse.

[0013] Preferably, the interior of the drying chamber is also equipped with rollers and a sealing block.

[0014] Rollers are rotatably mounted inside the drying chamber, and drying cotton is installed on the outside of the rollers;

[0015] A sealing block is symmetrically and fixedly installed on the upper and lower sides of the inside of the drying chamber, and a heating and drying tube is fitted inside the sealing block.

[0016] Preferably, the indoor ventilator forms an up-and-down lifting structure with the diversion pipe through the adjusting pipe, and the indoor ventilators arranged in parallel are fixed into an integrated structure by the fixing rod. The height position of the indoor ventilator is adjusted by the automatic lifting rod, and the indoor ventilator moves up and down correspondingly at the lower end of the diversion pipe through the adjusting pipe.

[0017] Preferably, the fan blades are fixedly connected to the bottom rotating shaft, and the bottom rotating shaft forms a synchronous transmission structure with the top rotating shaft through a transmission disc and a transmission belt. The transmission structure can control the rotation of the fan blades, so that the indoor ventilator drives the side fan blades to rotate during the up and down movement, and the fan blades can accelerate the flow of surrounding air.

[0018] Preferably, the top rotating shaft and the side gear are fixed as an integrated structure, and the side gear is meshed with the rack. During the up-and-down movement of the adjusting tube inside the diverter tube, the side gear rotates on the side of the rack under the meshing action.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the ventilation system of the potato storage warehouse adopts a new structural design, which makes it easy to control the indoor ventilation fan to move up and down, improve the ventilation range of the ventilation system in the warehouse, and the ventilation system is equipped with a drying structure, which can control the dryness and humidity of the airflow entering the warehouse and maintain the normal storage of potatoes.

[0020] 1. During operation, the ventilation system controls the automatic lifting rod to move the indoor ventilator up and down at a certain speed. This allows the indoor ventilator to extend and retract at the lower end of the diversion pipe via the regulating pipe, increasing the range of movement of the indoor ventilator. This expands the scope of the device's application in warehouse ventilation and improves the airflow effect in the warehouse. At the same time, the fan blades rotate accordingly under the transmission action, further accelerating the airflow velocity of the surrounding air when the indoor ventilator moves, thus assisting in air exchange.

[0021] 2. The outdoor ventilation fan is equipped with a drying chamber. When the gas enters the drying chamber, the humidity in the gas is absorbed by the drying cotton in the circulation. When the drying cotton passes through the inside of the sealing block, it is dried by the internal heating drying pipe. The drying cotton is quickly dried, so that the drying cotton maintains sufficient moisture absorption during the circulation process. This part of the structure keeps the gas entering the warehouse dry and avoids excessive humidity inside the warehouse after ventilation, which will affect potato storage.

[0032] A ventilation system for a potato storage warehouse includes:

[0033] The fixed rod 7 is welded and fixed to the outer side of the indoor ventilator 5, and the fan blade 8 is rotatably installed on the side of the indoor ventilator 5. The indoor ventilator 5 and the diversion pipe 3 are connected to each other by an automatic lifting rod 9.

[0034] The bottom rotating shaft 10 is rotatably installed inside the indoor ventilator 5, and the interior of the indoor ventilator 5 is connected to the interior of the regulating pipe 4. The top rotating shaft 11 is rotatably installed inside the regulating pipe 4, and a transmission disc 12 is fixedly installed on the outside of the top rotating shaft 11 and the bottom rotating shaft 10. A transmission belt 13 is installed on the outside of the transmission disc 12. Side gears 14 are symmetrically fixed on the left and right sides of the top rotating shaft 11.

[0035] Mounting plate 15 is fixedly installed inside the diversion pipe 3, and a rack 16 is fitted and fixed inside the mounting plate 15.

[0036] In this example, the outdoor ventilator 1 includes a drive chamber 101, a drying chamber 102, and an air supply chamber 103, and the interiors of the drive chamber 101, the drying chamber 102, and the air supply chamber 103 are interconnected. The interior of the drying chamber 102 is also provided with rollers 17 and sealing blocks 19: the rollers 17 are rotatably installed inside the drying chamber 102, and drying cotton 18 is installed on the outside of the rollers 17; the sealing blocks 19 are symmetrically fixedly installed on the upper and lower sides inside the drying chamber 102, and heating drying pipes 20 are fitted inside the sealing blocks 19.

[0037] During the operation of the ventilation system, the drive chamber 101 transmits gas to the drying chamber 102. The rollers 17 in the drying chamber 102 rotate under the drive of the micro motors installed on the side. During the transmission process, the drying cotton 18 is controlled to circulate in the drying chamber 102. During the circulation, the drying cotton 18 can absorb the moisture in the gas entering the drying chamber 102. When the drying cotton 18 rotates into the sealing block 19, it is dried by the heated drying pipe 20. This allows the drying cotton 18 to fully absorb the moisture in the transmitted gas during the circulation process. The dried gas enters the main pipe 2 through the air supply chamber 103 and flows into the indoor ventilator 5 in sequence through the diversion pipe 3 and the regulating pipe 4. The indoor and outdoor gases flow to each other through the ventilation grille 6, thereby completing the ventilation of the warehouse.

[0039] When the ventilation system is running, the automatic lifting rod 9 is controlled to push the indoor ventilator 5 up and down at a certain speed. The parallel indoor ventilators 5 move up and down synchronously under the action of the fixed rod 7. At this time, the regulating pipe 4 extends and retracts inside the diversion pipe 3, and the side gear 14 installed on the side of the regulating pipe 4 rotates on the side of the rack 16 under the action of meshing transmission. The side gear 14 controls the top rotating shaft 11 to rotate. The top rotating shaft 11 controls the bottom rotating shaft 10 at the lower end to rotate synchronously under the transmission action of the transmission disc 12 and the transmission belt 13. The bottom rotating shaft 10 controls the fan blades 8 connected to the side to rotate. Therefore, during the up and down movement of the indoor ventilator 5, the fan blades 8 rotate, which can accelerate the air flow speed around the indoor ventilator 5 and assist in the ventilation of the warehouse.

[0040] Working principle: When using this device, firstly according to... Figure 1-6The structure shown includes a drying chamber 102 in the outdoor ventilator 1. After the gas enters the drying chamber 102, it is dried by the drying cotton 18 in circulation, maintaining the dryness of the gas flow in the warehouse. At the same time, during the operation of the ventilation system, the indoor ventilator 5 is driven to move up and down.
