In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] As shown in the drawings Figure 1 , 2 , 3 and 4, the utility model provides a kind of high-efficiency air energy grain drying system, including grain storage tower 1, heat energy return air mechanism 2 and air supply module 3, one side of grain storage tower 1 is provided with heat energy return air mechanism 2, heat energy return air mechanism 2 includes dust removal module 21 and dehumidification and heating module 22, one side of dust removal module 21 is provided with dehumidification and heating module 22, one side of dehumidification and heating module 22 is provided with multiple groups of air supply module 3, the air inlet end of each group of air supply module 3 is communicated with dehumidification and heating module 22, the air outlet end of each group of air supply module 3 is communicated with grain storage tower 1, one side of grain storage tower 1 away from air supply module 3 is equipped with air guide pipe 4, one end of air guide pipe 4 is communicated with grain storage tower 1, the other end of air guide pipe 4 is communicated with dust removal module 21, while being provided with third fan 8 at the place of grain storage tower 1 close to air supply module 3, the air outlet end of third fan 8 is provided with third air pipe 9, one end of third air pipe 9 away from third fan 8 is communicated to the inside of grain storage tower 1.

[0024] The grain drying process involves: first, starting the third fan 9, which blows air into the grain storage tower 1 through the third duct 9, thus drying the grain inside the tower. The resulting low-temperature, high-humidity gas is then sent through the air duct 4 to the dust removal module 21 of the heat recovery mechanism 2. This module removes dust from the gas, which is then sent to the dehumidification and heating module 22 for heat exchange, drying and heating it. After drying and heating, the gas is returned to the grain storage tower 1 via the air supply module 3 for further hot air drying of the grain. This grain drying system effectively recovers and purifies the dust-laden, low-temperature, high-humidity gas generated during grain drying, saving energy and reducing drying costs.

[0025] As attached Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, and 8, a partition 5 is provided between the dust removal module 21 and the dehumidification heating module 22. Multiple dust collectors 6 are installed inside the dust removal module 21. By installing multiple dust collectors 6, the low-temperature and high-humidity gas generated during grain drying can be quickly dusted. One side of the dust collector 6 is connected to the partition 5, and the outlet end of the dust collector 6 is located on the side close to the partition 5 and extends through the partition 5 into the dehumidification heating module 22.

[0026] The subsequent dust collector 6 includes a frame 61, a storage box 62, a first fan 63, and a dust filter element 64. The storage box 62 is provided on the top of the frame 61. The first fan 63 is provided inside the storage box 62. The bottom of the storage box 62 has a first air inlet 621, and the air inlet end of the first fan 63 faces the first air inlet 621. A mounting bracket 65 is provided at the first air inlet 621. The dust filter element 64 is provided inside the mounting bracket 65 and extends into the interior of the frame 61. The storage box 62 has a first air outlet 622 on the side near the partition 5. The first air outlet 622 extends through the partition 5 into the dehumidification and heating module 22. The outlet end of the first fan 63 is connected to the first air outlet 622.

[0027] When a low-temperature, high-humidity gas containing dust enters: the first fan 63 inside the storage box 62 is activated to draw the dust-laden low-temperature, high-humidity gas into the dust removal module 21 into the first air inlet 621. Subsequently, the low-temperature, high-humidity gas is filtered and dust-removed by the dust removal filter element 64 installed at the first air inlet 621. After the dust removal and filtration are completed, the gas can enter the interior of the storage box 62 through the first air inlet 621. Finally, the first fan 63 discharges the dust-removed and filtered low-temperature, high-humidity gas inside the storage box 62 from the first air outlet 62 into the dehumidification and heating module 22 for drying and heating.

[0028] As attached Figure 1 , 2 As shown in 3, 4, 5, 6, 7 and 8, a cavity is subsequently opened inside the dehumidification and heating module 22, and multiple air-source heat pump dryers 7 are placed inside the cavity. The top surface of the air-source heat pump dryer 7 has a first air inlet 71, and the lower part of the outer surface of the air-source heat pump dryer 7 has a first air outlet 72. When the low-temperature and high-humidity gas that has been dusted enters the dehumidification and heating module 22, the air-source heat pump dryer 7 can be started to draw the low-temperature and high-humidity gas into the air-source heat pump dryer 7 through the first air inlet 71. The air-source heat pump dryer dries and heats the low-temperature and high-humidity gas. After drying and heating are completed, the low-temperature and high-humidity gas is converted into high-temperature and low-humidity gas, which is then discharged from the outside of the air-source heat pump dryer 7 through the first air outlet 72.

[0029] As attached Figure 4 and 5 As shown, the air-source dryer 7 is an existing mechanism, such as the drying equipment used in a negative pressure drying room as described in Chinese patent CN214620309U.

[0030] Furthermore, multiple second air outlets 221 are provided on the side of the dehumidification heating module 22 near the air supply module 3. Each second air outlet 221 is connected to the corresponding air supply module 3, so that the high-temperature and low-humidity gas in the dehumidification heating module 22 can enter the air supply module 3 through the second air outlet 221. Subsequently, by activating the air supply module 3, the high-temperature and low-humidity gas in the dehumidification heating module 22 can be sent into the grain storage tower 1. This enables the recovery, purification and reuse of the low-temperature and high-humidity gas with dust generated during grain drying, thereby saving energy consumption during drying and reducing grain drying costs.

[0031] As attached Figure 1 and 2As shown, the air supply module 3 comprises a first air pipe 31, a second fan 32, a second air pipe 33 and a support seat 34, the first air pipe 31 is arranged at the second air outlet 221, the end of the first air pipe 31 away from the second air outlet 221 is provided with the second fan 32, the bottom of the second fan 32 is provided with the support seat 34, the air inlet end of the second fan 32 is communicated with the first air pipe 31, the air outlet end of the second fan 32 is provided with the second air pipe 33, and the end of the second air pipe 33 away from the second fan 32 is communicated to the inside of the grain storage tower 1.

[0032] The high-temperature and low-humidity gas in the dehumidification and heating module 22 can enter the air suction place of the second fan 32 through the first air pipe 31, and then the second fan 32 is started, so that the high-temperature and low-humidity gas is discharged into the second air pipe 33, and then the high-temperature and low-humidity gas is sent into the inside of the grain storage tower 1 through the second air pipe 33, so that the high-temperature drying operation can be performed on the grain in the inside of the grain storage tower 1.

[0033] The above describes the embodiments of the utility model in detail in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
