Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cold chain logistics, and in particular to a cargo transmission channel for cold chain logistics. Background Art
[0002] Cold chain containers are special containers used for long-distance transportation and storage of perishable foods. After the cold chain container arrives at the destination, the stored food needs to be transferred to a cold storage for storage. When shipping, the food in the cold storage also needs to be transferred to the cold chain container for storage.
[0003] During the transfer process, the food generally needs to be transferred to a transfer vehicle first. The transfer vehicle then moves the food to a cold storage or cold chain container, and then unloads it and loads it into the storage or box. Since the transfer vehicle transfers a large amount of food each time, loading and unloading generally involves manual handling, which takes a long time. As a result, the food will stay on the transfer vehicle for a period of time. During this process, the food is prone to absorb heat from the outside, thereby increasing the probability of melting, deterioration, and shortening the shelf life.
[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention
[0005] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a cargo transmission channel for cold chain logistics which has a scientific design, does not absorb heat from the outside during transfer, is easy to operate, and has strong practicality.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a cargo transmission channel for cold chain logistics, comprising a conveying channel, an induced draft channel and a chain plate conveyor arranged in the conveying channel, one end of the conveying channel is a cold storage connecting end, and the other end is a container loading and unloading end, the air inlet end of the induced draft channel is connected to the cold storage, and the air outlet end is connected to the conveying channel, the air inlet end of the induced draft channel is arranged away from the cold storage connecting end of the conveying channel, and an induced draft device is arranged in the induced draft channel.
[0007] Based on the above, a sealed gate is provided at the cold storage connecting end of the conveying channel, and a leather curtain is provided at the container loading and unloading end. One end of the conveying channel is located inside the sealed gate, and the other end extends out of the leather curtain.
[0008] Based on the above, the air induced passage includes a first air outlet and a second air outlet, the first air outlet is connected to the cold storage connecting end, the second air outlet is connected to the container loading and unloading end, and the air induced device includes a first induced draft fan arranged in the first air outlet and a second induced draft fan arranged in the second air outlet.
[0009] Based on the above, the second air outlet is connected to the container loading and unloading end through an air duct, and the air outlet of the air duct is arranged toward the cold storage connecting end.
[0010] Based on the above, a heat-insulating layer is arranged outside the conveying channel.
[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:
[0012] (1) By arranging the chain plate conveyor in the conveying channel, with both ends extending to the cold storage and the container respectively, the food can be transported back and forth on the chain plate conveyor, and the induced air channel can transport the cold air in the cold storage to the conveying channel, so that the food maintains a low temperature environment during transportation, thereby avoiding problems such as melting, deterioration, shortening of shelf life, etc. caused by temperature increase.
[0013] (2) By providing the sealing gate at the connecting end of the cold storage, the air duct can be closed when food is not being transported. The provision of the leather curtain can reduce the overflow of cold air from the loading and unloading end of the container when food is being transported.
[0014] (3) By arranging the first air outlet and the second air outlet at both ends of the conveying channel, when the conveying is just started, the first induced draft fan can be turned on, the second induced draft fan can be turned off, and the leather curtain can be opened to quickly discharge the residual air in the conveying channel. Subsequently, the first induced draft fan can be turned off, the second induced draft fan can be turned on, and the leather curtain can be closed, so that the cold air can circulate in the conveying channel and the cold storage, thereby reducing energy loss.
[0015] (4) The air outlet of the air duct is arranged toward the connecting end of the cold storage, so that the cold air is blown back to the cold storage, further reducing the overflow of the cold air; the setting of the insulation layer reduces the heat exchange between the cold air and the external environment, thereby reducing energy consumption.

[0018] The technical solution of the utility model is further described in detail below through specific implementation methods.
[0019] like Figure 1As shown, a cargo transmission channel for cold chain logistics includes a conveying channel 1, an induced draft channel 2 and a chain plate conveyor 3 arranged in the conveying channel 1, one end of the conveying channel 1 is a cold storage connecting end, and the other end is a container loading and unloading end, the air inlet end of the induced draft channel 2 is connected to the cold storage 4, and the air outlet end is connected to the conveying channel 1, the air inlet end of the induced draft channel 2 is arranged away from the cold storage connecting end of the conveying channel 1, and an induced draft device is arranged in the induced draft channel 2.
[0020] During specific use, the two ends of the chain plate conveyor 3 are respectively extended to the cold storage 4 and the container. After the food is placed on the chain plate conveyor 3, the food can be transported back and forth between the cold storage 4 and the cold chain container. The air duct 2 can transport the cold air in the cold storage 4 to the conveying channel 1, so that the food maintains a low-temperature environment during transportation, avoiding problems such as melting, deterioration, and shortened shelf life due to increased temperature.
[0021] In order to further reduce energy consumption, a sealed gate 5 is provided at the cold storage connecting end of the conveying channel 1, and a leather curtain 6 is provided at the container loading and unloading end. One end of the conveying channel 1 is located on the inner side of the sealed gate 5, and the other end extends out of the leather curtain 6. The sealed gate 5 can close the air duct 2 when food is not being conveyed, and the leather curtain 6 can reduce the overflow of cold air from the container loading and unloading end when food is being conveyed.
[0022] The induced air passage 2 includes a first air outlet 7 and a second air outlet 8, wherein the first air outlet 7 is connected to the cold storage connection end, and the second air outlet 8 is connected to the container loading and unloading end, and the induced air device includes a first induced draft fan 9 disposed in the first air outlet 7 and a second induced draft fan 10 disposed in the second air outlet 8.
