Abstract
Description
Technical Field
[0001] This utility model relates to the field of potato storage technology, and in particular to a ventilation device for a potato storage room. Background Technology
[0002] Potatoes are one of China's five staple foods, renowned for their high nutritional value, adaptability, and high yield. They are the world's third most important food crop, after wheat and corn. Potatoes have both edible and medicinal value; however, they also contain some toxic alkaloids, such as solanine. Excessive intake can cause poisoning, nausea, and diarrhea. The solanine content in immature, green-skinned, and sprouted potatoes is dozens of times higher than in normally mature potatoes. Therefore, the timing of potato harvesting and storage techniques are crucial.
[0003] Currently, some people use potato cellars to store potatoes. A potato cellar consists of a cellar body and a cellar door. Potatoes are stored in the cellar body and ventilated through the cellar door. The drawback is that gas flow is poor and temperature and humidity cannot be guaranteed. In particular, the humidity and temperature in the center of the pile are too high, causing the potatoes to rot or sprout.
[0004] Therefore, it is necessary to provide a ventilation device for potato storage rooms to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a ventilation device for potato storage rooms.
[0006] This utility model provides a ventilation device for a potato storage room, comprising: multiple placement frames installed inside the storage room, the outer surface of the placement frames being connected to the inner surface of the storage room, a ventilation cavity being provided inside one end of each placement frame, two opposite inner sides of each placement frame being connected to the two ends of an air outlet pipe, the ventilation cavity being connected to one end of the air outlet pipe, multiple air outlet holes being provided on the circumferential side of the air outlet pipe, one end of adjacent vertical ventilation cavities being connected through an air inlet pipe, the top of one end of the uppermost ventilation cavity being connected to an external air inlet pipe, and the other end of the external air inlet pipe being connected to an air intake fan placed outside the storage room.
[0007] Preferably, the circumferential side of the air outlet pipe is provided with a plurality of protective grooves, the air outlet is located inside the protective grooves, and the inner diameter of the protective grooves is larger than the inner diameter of the air outlet.
[0008] Preferably, the other ends of the adjacent ventilation chambers are connected by an exhaust pipe, and the top of the other end of the uppermost ventilation chamber is connected to an external exhaust pipe, the other end of which is connected to an exhaust fan placed outside the storage room.
[0009] Preferably, the side of the ventilation cavity is provided with a plurality of second air outlets, and the second air outlets are the same size as the air outlets.
[0010] Preferably, the second air outlet is located inside the second protective groove, the second protective groove is disposed on the inner side of the placement frame, and the inner diameter of the second protective groove is larger than the inner diameter of the second air outlet.
[0011] Preferably, adjacent placement frames are connected by connecting rods, and the number of connecting rods is four, with the connecting rods arranged in a rectangular pattern.
[0012] Preferably, the air outlet and the second air outlet are frustum-shaped, the outer end of the air outlet is smaller than the other end, and the outer end of the second air outlet is smaller than the other end.
[0013] Compared with related technologies, the ventilation equipment for potato storage rooms provided by this utility model has the following beneficial effects:
[0014] 1. This utility model, by setting up an air intake fan, can send outside air into the uppermost ventilation chamber through the air intake fan, and then send it downwards through the air intake pipe into the lower ventilation chamber. The ventilation chamber sends the air into the air outlet pipe through one end, and then into the interior of the storage chamber through the air outlet hole. This promotes the flow of gas inside the storage chamber and prevents the potatoes from rotting or sprouting due to poor gas flow and insufficient temperature and humidity. In addition, by setting up multiple air outlet pipes, the potatoes can also be separated from each other to prevent them from being piled too tightly, which would cause poor gas flow and lead to excessive humidity and temperature in the center of the pile, causing the potatoes to rot or sprout.
[0015] 2. By setting a protective groove, this utility model can leave a gap between the vent hole and the outer surface of the vent pipe, preventing the potatoes from blocking the vent hole when placed, thus affecting the ventilation effect of the vent hole.
[0016] 3. By providing a second vent, air can be introduced into the storage chamber from another direction. By providing a second protective groove, a gap can be left between the second vent and the inner surface of the placement frame to prevent the potatoes from blocking the second vent and affecting the ventilation effect.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] refer to Figures 1 to 3 This utility model provides a ventilation device for a potato storage room, comprising: multiple placement frames 1 installed inside the storage room, the outer surface of the placement frame 1 being connected to the inner surface of the storage room, a ventilation chamber 12 being provided inside one end of the placement frame 1, the two opposite inner sides of the placement frame 1 being connected to the two ends of an air outlet pipe 3, the ventilation chamber 12 being connected to one end of the air outlet pipe 3, the peripheral side of the air outlet pipe 3 being provided with multiple air outlet holes 4, one end of adjacent ventilation chambers 12 being connected through an air inlet pipe 9, the top of one end of the uppermost ventilation chamber 12 being connected to an external air inlet pipe 5, and the other end of the external air inlet pipe 5 being connected to an air intake fan 6 placed outside the storage room.
[0023] It should be noted that by setting up an air intake fan 6, outside air can be sent into the uppermost ventilation chamber 12, and then sent down into the lower ventilation chamber 12 through the air intake pipe 9. The ventilation chamber 12 sends the air into the ventilation pipe 3 through one end, and then into the storage room through the air outlet 4. This promotes the flow of gas inside the storage room and prevents the potatoes from rotting or sprouting due to poor gas flow and insufficient temperature and humidity. In addition, by setting up multiple air outlet pipes 3, the potatoes can also be separated from each other to prevent them from being piled too tightly, which would cause poor gas flow, excessive humidity and temperature in the center of the pile, and thus cause the potatoes to rot or sprout.
[0024] In the embodiments of this utility model, reference is made to Figure 3 As shown, the vent pipe 3 has a plurality of protective grooves 11 on its peripheral side, and the vent hole 4 is located inside the protective groove 11. The inner diameter of the protective groove 11 is larger than the inner diameter of the vent hole 4.
[0025] It should be noted that by setting the protective groove 11, a gap can be left between the vent hole 4 and the outer surface of the vent pipe 3, so as to prevent the potatoes from blocking the vent hole 4 when they are placed, thus affecting the ventilation effect of the vent hole 4.
[0026] In the embodiments of this utility model, reference is made to Figure 2 As shown, the other ends of the adjacent ventilation chambers 12 are connected by an exhaust pipe 10. The top of the other end of the uppermost ventilation chamber 12 is connected to an external exhaust pipe 7. The other end of the external exhaust pipe 7 is connected to an exhaust fan 8 placed outside the storage room.
[0027] It should be noted that by setting up an exhaust fan 8, the exhaust gas in the storage room can be discharged through the exhaust fan 8, the external exhaust pipe 7 and the exhaust pipe 10 before the storage room is ventilated, so as to prevent the exhaust gas from polluting the gas introduced later.
[0028] In the embodiments of this utility model, reference is made to Figure 3 As shown, the side of the ventilation cavity 12 is provided with a plurality of second air outlets 13, and the second air outlets 13 are the same size as the air outlets 4.
[0029] In the embodiments of this utility model, reference is made to Figure 3 As shown, the second air outlet 13 is located inside the second protective groove 14, which is disposed on the inner side of the placement frame 1. The inner diameter of the second protective groove 14 is larger than the inner diameter of the second air outlet 13.
[0030] It should be noted that by setting the second vent 13, air can be introduced into the storage chamber from another direction. By setting the second protective groove 14, a gap can be left between the second vent 13 and the inner surface of the placement frame 1, so as to prevent the potatoes from blocking the second vent 13 when they are placed, thus affecting the ventilation effect of the second vent 13.
[0031] In the embodiments of this utility model, reference is made to Figure 1 As shown, adjacent placement frames 1 are connected by connecting rods 2. There are four connecting rods 2, which are arranged in a rectangular pattern.
[0032] It should be noted that by setting the connecting rod 2, the placement frames 1 can be connected to each other, thereby improving the stability of the placement frames 1 in the storage room.
[0033] In the embodiments of this utility model, reference is made to Figure 3 As shown, the air outlet 4 and the second air outlet 13 are truncated cones. The size of the outer end of the air outlet 4 is smaller than the size of the other end of the air outlet 4, and the size of the outer end of the second air outlet 13 is smaller than the size of the other end of the second air outlet 13.
[0034] It should be noted that by designing the air outlet 4 and the second air outlet 13 as having a smaller outer diameter and a larger inner diameter, the gas flow rate can be effectively increased when air is vented through the air outlet 4 and the second air outlet 13.
[0035] The working principle of the ventilation device for a potato storage room provided by this utility model is as follows:
[0036] By installing an intake fan 6, outside air can be sent into the uppermost ventilation chamber 12 and then into the lower ventilation chamber 12 through the intake pipe 9. The ventilation chamber 12 then sends the incoming air into the outlet pipe 3 through one end and into the storage room through the outlet hole 4. This promotes the flow of gas inside the storage room and prevents the potatoes from rotting or sprouting due to poor gas flow and insufficient temperature and humidity. In addition, by installing multiple outlet pipes 3, the potatoes can be separated from each other to prevent them from being piled too tightly, which would cause poor gas flow, excessive humidity and temperature in the center of the pile, and thus rotting or sprouting of the potatoes.
[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
