Description

Technical Field

[0001] This utility model relates to the field of cold storage ventilation technology, specifically to a ventilation device for storing and preserving fruits and vegetables in a cold storage facility. Background Technology

[0002] The ventilation technology used in cold storage of fruits and vegetables falls under the category of controlled atmosphere storage technology, which aims to extend the shelf life by adjusting the gas composition (such as the concentration of oxygen and carbon dioxide) in the cold storage.

[0003] In existing technologies, outside air is usually directly introduced into the cold storage. However, sending hot outside air into the cold storage will increase the storage temperature and the cooling load on the air cooler.

[0004] To address the aforementioned technical issues, CN215649076U discloses a ventilation device for cold storage and preservation of fruits and vegetables. Hot outside air enters the cooling chamber, is sprayed onto the cooling coils and heat-conducting fins through a water inlet pipe and atomizing nozzles, and is then cooled. The cooled air enters the drying chamber, is dried and condensed by the partition, and is discharged through the air outlet pipe into the cold storage. This ensures that the air enters the cold storage at a low temperature, thereby reducing the impact of outside air on the temperature rise of the cold storage. This helps maintain a constant temperature inside the storage, reduces the load on the refrigeration unit, lowers energy consumption, and effectively ensures the refrigeration effect. The temperature inside the cold storage is easy to maintain and control, making it suitable for the long-term storage of fruits, vegetables, and various agricultural by-products, and is easy to promote and use.

[0005] The aforementioned existing technology also has the following shortcomings: when cooling the gas entering the cold storage, water cooling is used, which increases the required equipment and requires refrigeration, water circulation and water storage equipment. Therefore, the increase in equipment leads to increased energy consumption and waste of water resources. Utility Model Content

[0006] The purpose of this utility model is to provide a ventilation device for cold storage and preservation of fruits and vegetables. It has the advantage of being able to cool the gas entering the cold storage during the ventilation process, and at the same time, it also has the advantage of energy saving. It uses cold air extracted from the cold storage to pre-treat the fresh gas, and then completes the ventilation operation, so as to reduce energy consumption in all aspects and reduce the required equipment, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cold storage and preservation ventilation device for fruits and vegetables, comprising a box body;

[0008] The box is equipped with an air intake mechanism for ventilation, a distribution mechanism for cooling the gas inside the air intake mechanism, and an exhaust mechanism for discharging cold air at the bottom of the box.

[0016] A connecting block is fixedly installed at the top of the distribution cylinder, and a top cover is fixedly installed at the top of the connecting block.

[0017] Preferably, the conveying assembly includes;

[0019] Preferably, the extraction component includes;

[0020] An exhaust fan is fixedly installed on the inner wall of the air supply pipe, and a second mesh is bolted to one end of the air supply pipe.

[0021] Preferably, the air intake mechanism includes;

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides a cold storage and preservation ventilation device for fruits and vegetables, including a box body 1;

[0036] The box 1 is equipped with an air intake mechanism 3 for ventilation, and the box 1 is also equipped with a distribution mechanism 2 for cooling the gas inside the air intake mechanism 3. The bottom of the box 1 is equipped with an exhaust mechanism 4 for discharging cold air.

[0037] Distribution mechanism 2 includes;

[0038] The air distribution assembly is located inside the cabinet 1, and a shielding component is provided on the top of the air distribution assembly;

[0039] The exhaust mechanism 4 includes;

[0040] The conveying assembly is located at the bottom of the housing 1, and the conveying assembly contains an extraction assembly.

[0041] Preferred;

[0042] like Figure 3 As shown, the air conditioning distribution assembly includes;

[0043] The support rod 21 is fixedly installed at the bottom of the inner cavity of the box 1. The top of the support rod 21 is fixedly installed with a distribution cylinder 22 and a distribution hole 23 opened on the outside of the distribution cylinder 22, so as to realize the absorption of cold air and its distribution to the inside of the box 1, thereby realizing uniform cooling operation.

[0044] further;

[0045] like Figure 3 As shown, the shading component includes;

[0046] The connecting block 24 is fixedly installed on the top of the distribution cylinder 22. The top of the connecting block 24 is fixedly installed with a top cover 25 to prevent cold air from being directly discharged from the top. The cover is used to make the cold air discharge to the outside.

[0047] Going a step further;

[0048] like Figure 5 As shown, the conveying assembly includes;

[0049] The exhaust pipe 41 is connected to the bottom of the housing 1. The air inlet end of the exhaust pipe 41 is connected to the air supply pipe 42, which can transport gas and discharge cold air into the interior of the housing 1 and into the distribution cylinder 22.

[0050] in;

[0051] like Figure 5 As shown, the extraction component includes;

[0052] An exhaust fan 43 is fixedly installed on the inner wall of the air supply pipe 42. One end of the air supply pipe 42 is connected to a second partition 44, which can draw cold air from the cold storage into the interior of the air supply pipe 42, while the second partition 44 serves as a barrier and protection.

[0053] It is worth explaining;

[0054] like Figure 4 As shown, the air intake mechanism 3 includes;

[0055] The coil 31 is fixedly installed inside the housing 1. The air inlet end of the coil 31 is connected to the air inlet pipe 32 and the first air inlet fan 33 fixed inside the air inlet pipe 32. One end of the air inlet pipe 32 is bolted with a filter module 34.

[0056] The air intake pipe 32 and the first air intake fan 33 facilitate the intake of fresh external air into the coil 31. Before entering, the air will be filtered by the filter module 34. At the same time, the air will be conveyed in a curved manner as it passes through the coil 31 until it enters the cold storage through the ventilation pipe 35.

[0057] The gas is cooled when it enters the coil 31.

[0058] The ventilation pipe 35 is connected to the exhaust end of the coil 31. A second intake fan 36 is fixedly installed inside the ventilation pipe 35, and a first partition net 37 is bolted to the exhaust end of the ventilation pipe 35.

[0059] The second intake fan 36 can accelerate the intake efficiency, while the first mesh 37 can also block and protect the exhaust position.

[0060] During ventilation, the exhaust fan 43 is activated in advance to draw cold air from the cold storage and discharge it into the box 1 and the interior of the distribution cylinder 22 through the exhaust pipe 41. The air is then discharged through the top of the distribution cylinder 22, and the air discharged from the top is blocked by the top cover 25, causing it to be discharged to the outside. The distribution hole 23 allows the cold air to be discharged directly to the outside after entering the distribution cylinder 22, further increasing the uniformity of the internal cold air distribution, thereby accelerating the cooling efficiency of the coil 31 inside the box 1. The above-mentioned pipes can be made of copper or aluminum to ensure the efficiency and effect of the cooling pretreatment.

[0061] Once the required temperature is reached, the first intake fan 33 is activated to draw in fresh air from outside. The air is pre-treated by the filter module 34 and then enters the interior of the coil 31. As mentioned above, the air is cooled as it passes through the coil 31 and then enters the ventilation pipe 35 to be directly discharged into the cold storage. To ensure exhaust efficiency, the second intake fan 36 can be selectively turned on and the power of the second intake fan 36 and other fans can be adjusted. At the same time, to avoid increasing the air pressure inside the cabinet 1, the exhaust operation can be carried out by adjusting the flow rate of the exhaust valve pipe 7. After the above treatment, the fresh air can be cooled without the need for additional refrigeration equipment, thus achieving energy saving.

[0062] in addition;

[0063] like Figure 2 As shown, a mounting bracket 5 is fixedly installed on the back of the box 1, an insulation layer 6 is fixedly installed on the outside of the box 1, and an air outlet valve pipe 7 is connected to one side of the box 1.

[0064] Mounting bracket 5 can be used to mount box 1, while insulation layer 6 can insulate the interior of box 1.

[0065] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
