[0026] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0027] In the related art, the feed needs to be cooled and dried after pelleting. The feed is generally cooled and dried using a cooling tower, which is equipped with an air inlet duct. After the feed enters the cooling tower, it is left to stand, and then the air inlet duct continuously transports dry cold air into the cooling tower. The dry cold air flows out of the cooling tower after passing through the feed, thereby taking away the heat and water vapor of the feed. However, the utilization rate of dry cold air in traditional cooling towers is low, which increases energy consumption in disguise.

[0028] In view of the technical problems involved in the related technologies, the utility model proposes a feed cooling and dehumidifying device to solve the related technical problems. The tower body of the feed cooling and dehumidifying device is provided with multiple drying zones, and the gas pipeline sequentially connects the multiple drying zones and continuously delivers cooling and dehumidifying gas to the multiple drying zones. After the feed enters the drying zone on the top layer, it stays for a certain period of time, and then the partition rotates, and the feed enters the drying zone on the next layer, and so on, until it is completely dried. In this process, the temperature and humidity of the gas gradually increase from bottom to top, and the temperature and humidity of the feed gradually decrease from bottom to top. The temperature and humidity of the feed are always higher than the temperature and humidity of the gas entering the drying zone, which effectively improves the utilization rate of the gas, and the feed is divided into multiple portions and stays in the tower body, with high drying efficiency and reduced energy consumption.

[0029] Reference Figure 1 and Figure 2 The feed cooling and dehumidifying device comprises a tower body 100 and a gas pipeline 110, wherein the tower body 100 is placed vertically, and a plurality of partitions 120 are arranged in the height direction of the tower body 100, and the inner cavity of the tower body 100 is divided by the partitions 120 to form a plurality of drying zones 150. The partitions 120 can rotate so that adjacent drying zones 150 are connected. The gas pipeline 110 is arranged outside the tower body 100, and the gas pipeline 110 sequentially connects the plurality of drying zones 150, and the adjacent drying zones 150 are not directly connected, and the adjacent drying zones 150 are connected through the gas pipeline 110, and the gas enters the inner cavity of the tower body 100 from the gas pipeline 110, and after passing through one drying zone 150, flows into the gas pipeline 110 between two drying zones 150, and then enters the next drying zone 150.

[0030] It can be understood that the air inlet end of the gas pipeline 110 is located in the drying area 150 at the bottom of the tower body 100, and the air outlet end of the gas pipeline 110 is located in the drying area 150 at the top of the tower body 100, and the gas pipeline 110 sequentially connects multiple drying areas 150 from bottom to top. The gas enters from the lower end of the tower body 100, then climbs up along the tower body 100, and passes through multiple drying areas 150 in sequence, which can reduce the gas flow rate from bottom to top, which helps the gas to fully contact with the feed to achieve drying and cooling.

[0031] It is understandable that the tower body 100 is provided with a guide portion 111, the guide portion 111 is located on the air inlet side of the drying area 150, the guide portion 111 is connected to the gas pipeline 110, and can guide the airflow to flow in the direction of the partition 120. The guide portion 111 is a guide cover. The bottom of the tower body 100 is provided with an openable discharge portion 130. It should be noted that in other embodiments, the guide portion 111 can be a guide tube, the guide tube is downward, the guide tube is located at the end of the gas outflow direction, and the guide tube is generally provided with a cutout.

[0032] It can be understood that the material discharging part 130 is provided with a limit plate 132 and two rotating plates 131, the two rotating plates 131 are symmetrical to each other, and the ends of the two rotating plates 131 that are away from each other are provided with a rotating shaft, and the rotating plates 131 can be rotated to an open position and a closed position. When the rotating plates 131 are in the open position, the ends of the two rotating plates 131 are separated from each other, and the limit plate 132 is in a position separated from the rotating plates 131; when the rotating plates 131 are in the closed position, the ends of the two rotating plates 131 abut against each other, and the limit plate 132 extends to the bottom of the rotating plates 131 and supports the rotating plates 131. When the rotating plates 131 are in the process of switching from the closed position to the open position, the limit plate 132 first moves horizontally until it is separated from the rotating plates 131, and then the rotating plates 131 rotate around the rotating shaft until the two rotating plates 131 are in a vertical state, so that the material discharging part 130 is opened.

[0033] Reference Figure 1 The feed cooling and dehumidifying device further includes a cooling dehumidifier 140, which is connected to the air inlet and the air outlet of the air pipeline 110. A plurality of temperature sensors are arranged in the tower body 100, and a plurality of drying zones 150 are provided with temperature sensors. A plurality of humidity sensors are arranged in the tower body 100, and a plurality of drying zones 150 are provided with humidity sensors.

[0034] It is understandable that the temperature sensor and the humidity sensor can better monitor the temperature and humidity of the feed in the drying area 150, which is conducive to opening the partition 120 at a timely manner to transport the feed to the next layer.

[0035] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
