Description

Technical Field

[0001] The utility model relates to the technical field of automatic ventilation, and more specifically, to an automatic ventilation structure for a heat-insulating refrigerated vehicle. Background Art

[0002] A refrigerated truck refers to a closed van transport truck used to maintain the temperature of frozen or fresh goods. A refrigerated truck is a special refrigerated transport vehicle equipped with a refrigeration unit and a polyurethane insulated compartment. In a refrigerated truck, in order to transport live animals, plants and other products, an automatic ventilation structure needs to be installed in the compartment. By using the automatic ventilation structure, the air in the insulated refrigerated compartment can circulate with the outside air, thereby ensuring that the internal environment of the compartment is suitable. General insulated refrigerated trucks rely on the skylight on the top of the compartment to achieve the exchange of air in the compartment with the air outside the compartment. The ventilation efficiency is low, and the ventilation is not controlled by humans. Dust and debris can easily enter the compartment, and the odor in the outside air cannot be removed. The odor of the refrigerated products in the compartment cannot be eliminated, which makes the refrigerated products easily damaged. Utility Model Content

[0003] Technical issues to be solved

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an automatic ventilation structure for an insulated refrigerated truck, which has the characteristics of manually controlled automatic ventilation, high ventilation efficiency, and convenient operation. It can prevent debris, dust, and odors in the air from entering the refrigerated compartment when the air outside the compartment is extracted, thereby solving the problem of odors of refrigerated products being difficult to remove and damaging the refrigerated products.

[0005] Technical Solution

[0006] To achieve the above-mentioned purpose, the utility model provides an automatic ventilation structure for an insulated refrigerated truck, comprising a first box body and a pipeline, the upper surface of the first box body is fixedly connected to a pipeline, the upper surface of the pipeline is fixedly connected to a support column, the upper end of the support column is fixedly connected to a protective piece, the surface of the support column is fixedly connected to a first mesh cover, a glass fiber filter plate and a first activated carbon filter plate are fixedly connected to the inside of the pipeline, and the glass fiber filter plate is arranged above the first activated carbon filter plate.

[0007] When an automatic ventilation structure of an insulated refrigerated truck using the technical solution is used, a glass fiber filter plate, a first activated carbon filter plate, a protective member, a second activated carbon filter plate and a second mesh cover are arranged. When the quality of the air outside the compartment drawn by people is not good, leaves and large impurities in the air can be filtered out through the first mesh cover. After the air enters the pipe, dust and some fine particles in the air can be filtered out through the glass fiber filter plate. The odor in the air can be filtered out through the first activated carbon filter plate to avoid affecting the refrigerated products in the compartment. When the refrigerated air in the compartment is discharged, the odor emitted by the refrigerated products is filtered out through the second activated carbon filter plate to avoid air pollution. The protective member arranged above the pipeline prevents rainwater or other debris from entering the pipeline on rainy days. The second mesh cover at the air outlet of the second box body prevents leaves or residues in the air from affecting the normal operation of the exhaust chamber, plays a protective role, and improves the practicality of the device.

[0008] Furthermore, an exhaust chamber is provided inside the first box body, the exhaust chamber is communicated with a pipeline, a first support frame is fixedly connected inside the exhaust chamber, the first support frame has two groups, and an exhaust fan is fixedly connected in the middle of the first support frame.
