[0003] However, in the process of using the drying equipment in the prior art, a hot air blower is usually used to blow high-temperature air to the surface of the grain to dry the grain. However, since the grain is piled up to a certain thickness, after the upper layer of grain is dried, the lower layer of grain may still not meet the drying requirements, and a secondary drying process is required, which increases the processing cost and makes it difficult to dry the grain evenly.
[0004] In the process of drying grains, hot and humid air will accumulate on the top of the equipment. In order to avoid affecting the drying of grains, it needs to be discharged. However, this part of hot and humid air contains a lot of heat energy. Direct discharge causes a lot of heat energy loss, and it is difficult to recycle the heat energy in the upper layer of hot and humid air.
[0005] In view of the above technical defects, a solution is now proposed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Embodiment 1:
[0028] This embodiment is used to solve the problem that during use of the drying equipment in the prior art, due to the certain thickness of the accumulated grain, after the upper layer of grain is dried, the bottom layer of grain may still not meet the drying requirements and need to be dried again, which increases the processing cost and makes it difficult to dry the grain evenly.
[0029] See also Figure 1 - Figure 3As shown, this embodiment is a circulating air-drying device for drying grains, including a frame 1, a feed hopper 101 is fixedly installed on the top of the frame 1, a discharge port 102 is opened at one end of the frame 1, an air-drying component 2 is fixedly installed inside the frame 1, the air-drying component 2 is located below the feed hopper 101, and the air-drying component 2 includes a plurality of bases 201 and a vibration plate 202, the base 201 is fixedly installed on the bottom of the frame 1, and the base 201 is movably connected with a buffer rod 203, and one end of the buffer rod 203 away from the base 201 is fixedly connected to the bottom of the vibration plate 202, and a vibration spring 204 is sleeved on the buffer rod 203, one end of the vibration spring 204 is fixedly connected to the bottom of the vibration plate 202, and one end of the vibration spring 204 is fixedly connected to the base 201.
[0030] During the vibration of the vibration plate 202, the buffer rod 203 moves up and down inside the base 201. The buffer rod 203 can guide the vibration plate 202 on the one hand to prevent it from shaking left and right, and on the other hand, it can limit the vibration amplitude of the vibration plate 202 to prevent the amplitude from being too large and causing food to fly out of the vibration plate 202.
[0031] The air-drying component 2 also includes a rotating rod 205, a plurality of fixed seats 206 are fixedly installed at the bottom of the frame 1, the rotating rod 205 is movably installed in the fixed seat 206, a plurality of cams 207 are fixedly installed on the rotating rod 205, the protruding ends of the cams 207 are against the bottom of the vibration plate 202, and the end of the rotating rod 205 away from the discharge port 102 is fixedly connected to a rotating head 208, and a plurality of connecting rods 209 are fixedly installed on the rotating head 208, and the connecting rods 209 are evenly distributed in the circumferential direction of the rotating head 208, and a wind cup 210 is fixedly installed on the end of the connecting rod 209 away from the rotating head 208, and the position of the wind cup 210 is adapted to the air outlet end of the hot air blower 4.
[0032] The grain is input from the feed hopper 101 to the vibration plate 202. At this time, the hot air blower 4 is started to blow air of a certain temperature into the interior of the frame 1. At the same time, the wind cup 210 drives the rotating head 208 and the rotating rod 205 to rotate under the action of the hot air blower 4. Under the joint action of the cam 207, the vibration spring 204 and the buffer rod 203, the vibration plate 202 begins to vibrate up and down periodically, and then uses the vibration to turn the grain. After the temperature inside the frame 1 is stable, the exhaust fan 5 is started to extract the upper humid hot air inside the frame 1. At this time, a certain air pressure is formed within the range of the exhaust fan 5, and the hot air flows from the hot air blower 4 to the exhaust fan 5, thereby drying the turned grain. During the drying process, the hot air passes through the gaps between the grains, and the grain can be dried as a whole at the same time, and there will be no uneven drying. The hot air is not blown directly to the surface of the grain, which effectively prevents the grain from being blown away by the wind. Therefore, a larger power hot air blower 4 can be used, and the drying efficiency is high.
[0033] The hot air blower 4 and the air drying component 2 are used in combination to achieve uniform drying of the grain.
[0034] Embodiment 2:
[0035] This embodiment is used to solve the problem that during the process of drying grains, hot and humid air accumulates on the top of the equipment. In order to avoid affecting the drying of the grains, it needs to be discharged. However, this part of hot and humid air contains more heat energy, and direct discharge causes a large amount of heat energy loss, making it difficult to recycle the heat energy in the upper layer of hot and humid air.
[0036] See also Figure 4 - Figure 7 As shown, the utility model also includes a filter box 3, a hot air blower 4 and an exhaust fan 5, the filter box 3, the hot air blower 4 and the exhaust fan 5 are all fixedly installed on the same side of the frame 1, the exhaust fan 5 is located above the hot air blower 4, the filter box 3 is located between the exhaust fan 5 and the hot air blower 4, the exhaust fan 5 is arranged near the end of the frame 1 away from the feed hopper 101, the hot air blower 4 is arranged near the end of the frame 1 away from the discharge port 102, the air outlet end of the hot air blower 4 is connected to the inside of the frame 1, the exhaust end of the exhaust fan 5 is connected to the inside of the frame 1, the exhaust end of the hot air blower 4 is connected to the inside of the filter box 3 through a pipeline, the air outlet end of the exhaust fan 5 is fixedly connected to the side of the filter box 3 away from the hot air blower 4 through a pipeline, a filter plate 301 and a heating plate 302 are fixedly installed in the filter box 3, the heating plate 302 is arranged near one end of the hot air blower 4, and the filter plate 301 is arranged near one end of the exhaust fan 5.
[0037] After the grain is just transported to the vibration plate 202, the heating plate 302 is turned on. At this time, the power of the heating plate 302 is maximum, and the exhaust fan 5 is started to extract air. After the air passes through the heating plate 302, the temperature increases. As the temperature inside the frame 1 stabilizes, the exhaust fan 5 is started to extract the upper layer of humid hot air. The extracted humid hot air is dried and then transported to the hot air blower 4 again. Since the air extracted by the hot air blower 4 has a certain temperature at this time, the power of the heating plate 302 can be lowered, which effectively saves energy without affecting the drying of the grain.
[0038] While the hot air blower 4 is drying the grain, the exhaust fan 5 extracts the hot and humid air inside the frame 1, and the extracted hot and humid air is transported to the filter box 3 through a pipeline, and the filter plate 301 is used to adsorb water molecules in the hot and humid air. After the filtration is completed, the dry hot air passes through the heating plate 302 and is transported to the hot air blower 4 through a pipeline, and then the hot air blower 4 blows it into the frame 1 to dry the grain, completing the hot air circulation.
[0039] The heat energy in the upper layer of hot and humid air can be recovered and utilized by using the hot air blower 4, the exhaust fan 5 and the filter box 3 in coordination.
[0040] In combination with Example 1 and Example 2, by using the hot air blower 4 and the air-drying component 2 in coordination, the vibration plate 202 is used to turn the grain, and the grain is air-dried while turning it, thereby effectively improving the air-drying effect. The hot and humid air inside the frame 1 is extracted by the exhaust fan 5, and after extraction, it is filtered and returned to the hot air blower 4 to complete the hot air circulation. By using the air-drying component 2, the hot air blower 4 and the exhaust fan 5 in coordination, the grain is evenly dried and the heat energy of the upper layer of hot and humid air is recovered and utilized.
[0041] The working process and principle of the utility model are as follows:
[0042] Grain is input from the feed hopper 101 to the vibration plate 202. At this time, the hot air blower 4 is started to blow air of a certain temperature into the interior of the frame 1. At the same time, the wind cup 210 drives the rotating head 208 and the rotating rod 205 to rotate under the action of the hot air blower 4. Under the joint action of the cam 207, the vibration spring 204 and the buffer rod 203, the vibration plate 202 begins to vibrate up and down periodically, and then uses the vibration to turn the grain. After the temperature inside the frame 1 stabilizes, the exhaust fan 5 is started to extract the upper humid hot air inside the frame 1. At this time, a certain air pressure is formed within the range of the exhaust fan 5, and the hot air flows from the hot air blower 4 to the exhaust fan 5, so as to dry the turned grain. During the drying process, the hot air passes through the gaps between the grains, and the grain can be dried as a whole at the same time, and there will be no uneven drying, which effectively improves the drying efficiency.
[0043] While the hot air blower 4 is drying the grain, the exhaust fan 5 extracts the hot and humid air inside the frame 1, and the extracted hot and humid air is transported to the filter box 3 through a pipeline, and the filter plate 301 is used to adsorb water molecules in the hot and humid air. After the filtration is completed, the dry hot air passes through the heating plate 302 and is transported to the hot air blower 4 through a pipeline, and then the hot air blower 4 blows it into the frame 1 to dry the grain, completing the hot air circulation.
[0044] By using the air drying component 2, the hot air blower 4 and the exhaust fan 5 in combination, the grains can be dried evenly while the heat energy of the upper layer of moist and hot air can be recycled.
