Technical Field

[0001] The utility model relates to the technical field of feed processing cooling equipment, in particular to a visible counter-current cooler. Background Art

[0002] In the process of feed pellet production, the temperature of pellets coming out of the pellet press is as high as 90°C and must go through a cooling process to achieve the purpose of cooling and dehydration. The countercurrent cooler is the most advanced pellet feed cooling technology in the world. It is a new generation of cooling equipment developed by research and development, mainly used for cooling high-temperature pellet feed after pelleting.

[0003] Application number: CN205175196U; discloses a countercurrent cooler, the main points of its technical solution are: a cooling chamber, the interior of which is a cavity for accommodating materials, a feeding device is provided at the upper part of the cooling chamber, the top of the feeding device is sealed by a top cover, an air suction port is provided on the top cover, and a discharge device is provided at the bottom of the cooling chamber. The technical effect of the utility model is as follows: a refrigeration chamber composed of a conical table and a partition arranged around the inner wall of the conical table is arranged on the basis of a traditional countercurrent cooler; the refrigeration chamber is made of metal aluminum or aluminum alloy material and has better thermal conductivity; when the material reaches the first feed space surrounded by the refrigeration chamber through the cold liquid injected into the refrigeration chamber, the cold liquid wraps the material therein and exchanges heat with the material, thereby achieving the effect of secondary cooling of the material; if it is necessary to further enhance the cooling effect, the sealing cover can be closed to allow the material to stay in the refrigeration chamber for a longer time, and then the sealing cover can be opened to take out the material; the countercurrent cooler of the utility model improves the cooling effect of the material, eliminates the step of placing the material in the air for drying in the traditional process, and the equipment has a simple structure, low cost and convenient operation.

[0004] The air inlet device of the above-mentioned comparative documents is in direct contact with the external environment. When not in use, dust and impurities from the outside can easily enter the interior of the equipment, causing dust accumulation inside the equipment, thus affecting the subsequent feed processing quality. At the same time, since the interior of the equipment is closed, the outside world cannot timely detect the situation inside the equipment, so it is difficult to understand the production situation in time. To address the above problems, we have launched a visual countercurrent cooler. Utility Model Content

[0026] The utility model provides a visible counter-flow cooler through improvement, such as Figure 1-Figure 4 As shown, it includes a first cooling chamber 1, a first air inlet chamber 2 is arranged on the top of the first cooling chamber 1, a second cooling chamber 3 is arranged on the top of the first air inlet chamber 2, a second air inlet chamber 4 is arranged on the top of the second cooling chamber 3, and a protective mechanism is arranged inside the first air inlet chamber 2 and the second air inlet chamber 4; the protective mechanism includes an air inlet 5, the air inlet 5 is opened inside the four faces of the first air inlet chamber 2 and the second air inlet chamber 4, a sliding groove is opened inside the first air inlet chamber 2 and the second air inlet chamber 4, and a protective plate 6 is slidably connected inside the sliding groove; the protective plate 6 is provided with an opening and closing mechanism for opening and closing the air inlet 5; the first cooling chamber 1 and the second cooling chamber 3 are both provided with a visual mechanism for monitoring the internal situation. The internal structures of the first cooling chamber 1 and the second cooling chamber 3 are the same, and the internal structures of the first air inlet chamber 2 and the second air inlet chamber 4 are the same.

[0027] In the present embodiment: first, when cooling the feed entering the first cooling chamber 1 and the second cooling chamber 3, cold air is input into the first cooling chamber 1 and the second cooling chamber 3 through the air inlet 5, and the feed is cooled by the cold air. By arranging the first cooling chamber 1 and the second cooling chamber 3 and the first air inlet chamber 2 and the second air inlet chamber 4 with the same structure, the feed can be doubly cooled to ensure the cooling effect.

[0028] In the above scheme, the feed needs to be added and discharged after cooling. The specific operations are as follows:

[0029] like Figure 1 As shown, a feed bin 12 is fixedly connected to the top of the second cooling chamber 3, a feed port 13 is fixedly connected to the top of the feed bin 12, a discharge bin 19 is provided below the first cooling chamber 1, and a discharge port 20 is provided at the bottom of the discharge bin 19;

[0030] In this embodiment: the feed is placed into the feed bin 12 through the feed port 13, then enters the second cooling chamber 3 through the feed bin 12, and then falls into the first cooling chamber 1. After cooling, the feed enters the discharge bin 19 and is discharged through the discharge port 20.

[0031] In the first embodiment, when the device is used and when the device is not used, the height of the protective plate 6 needs to be adjusted, and the specific operation is as follows:
