[0024] ​​In the embodiment, the protective cover 2 is installed outside the feed inlet 3, which can prevent foreign matters from falling into the feed inlet 3, and provide a relatively closed space for the subsequent air suction pipe 7 to collect dust, so as to avoid the spread of dust to a larger range. The air outlet cover 4 is in communication with the inside of the drying equipment main body 1 and is connected with the air inlet pipe 5 and the hot air fan 6. The hot air fan 6 generates hot air, which enters the drying equipment main body 1 through the air inlet pipe 5 and the air outlet cover 4, so as to provide heat for drying the rapeseeds. The air suction pipe 7 is fixed inside the feed inlet 3. The heat exchange copper pipe 8 inside the air suction pipe 7 can absorb the heat of water vapor. The air suction pipe 7 cooperates with the driving motor 9 and the fan wheel 10 to work, so as to suck the dust flying during feeding. The heat exchange copper pipe 8 is connected with the heat exchange assembly 11 through the communication pipe 81, which is used to absorb the heat of water vapor and transfer it to the heat exchange assembly 11, so as to realize heat energy recycling. The heat exchange assembly 11 is installed at the input end of the hot air fan 6, which can use the recycled heat energy to preheat the air entering the hot air fan 6, reduce the heating power of the heating element of the hot air fan 6, reduce the power consumption, improve the energy utilization rate, and reduce the drying cost.

[0025] Specifically, the driving motor 9 is fixedly installed on the outer surface of the air suction pipe 7. The output end of the driving motor 9 is fixedly connected with the fan wheel 10. The fan wheel 10 is rotatably connected to the inner bottom end of the air suction pipe 7. The inner top end of the air suction pipe 7 is in communication with the inside of the protective cover 2.

[0026] In the embodiment, the driving motor 9 drives the fan wheel 10 to rotate. The fan wheel 10 is rotatably connected to the inner bottom end of the air suction pipe 7, so that a negative pressure is formed in the air suction pipe 7. On the one hand, the dust particles flying during the pouring of rapeseeds into the feed inlet 3 can be sucked into the air suction pipe 7, so as to avoid the pollution of the working environment caused by the flying dust. On the other hand, the water vapor is condensed into water droplets in the air suction pipe 7, which will flow to the end of the air suction pipe 7 together with the dust, so as to reduce the erosion of the dust to the inside of the equipment, which is beneficial to prolong the service life of the equipment.

[0027] Specifically, the heat exchange assembly 11 includes a metal coil pipe 113 spirally fixed in the air inlet cylinder 111. The input end of the metal coil pipe 113 is fixedly installed with a circulating water pump 114. The output end of the circulating water pump 114 is in communication with the input end of the heat exchange copper pipe 8 through one of the communication pipes 81. The output end of the metal coil pipe 113 is in communication with the output end of the heat exchange copper pipe 8 through the other communication pipe 81. The air inlet cylinder 111 is provided with an air inlet hole 112 at the surface center close to the hot air fan 6. The input end of the hot air fan 6 is in communication with the inside of the air inlet cylinder 111 through the air inlet hole 112.

[0028] In the embodiment, the circulating water pump 114 delivers the hot water after absorbing heat in the heat exchange copper pipe 8 to the metal coil pipe 113. When the hot air fan 6 is working, the air sucked in enters the air inlet hole 112 in the air inlet cylinder 111 and exchanges heat with the metal coil pipe 113 spirally arranged inside the air inlet cylinder 111 for preheating, which increases the temperature of the air entering the hot air fan 6, reduces the heating power of the heating components inside the hot air fan 6, makes the air easier to be heated, thereby reducing the power consumption, improving the energy utilization rate, and reducing the drying cost.

[0029] Specifically, when the air suction pipe 7 is in a negative pressure state, the heat exchange copper pipe 8 is spirally fixedly connected to the inner wall of the air suction pipe 7.

[0030] In the embodiment, the air suction pipe 7 is in a negative pressure state due to the rotation of the air blade wheel 10, which effectively sucks in dust and strengthens the environmental protection during use of the equipment. The spiral heat exchange copper pipe 8 increases the contact area with water vapor, can more efficiently absorb the heat carried by the water vapor, and improves the heat energy recovery efficiency.

[0031] Specifically, the top of the air suction pipe 7 and the top of the feeding port 3 both extend to the inside of the protective cover 2, and the outer surface of the connecting pipe 81 is fixedly sleeved with a heat preservation sleeve.

[0032] In the embodiment, the top of the air suction pipe 7 and the top of the feeding port 3 extend to the inside of the protective cover 2, so that a relatively closed space is formed near the feeding port 3, which is more conducive to the collection of dust and water vapor by the air suction pipe 7 in a negative pressure state and avoids the escape of the dust and water vapor to the outside environment. The heat preservation sleeve fixedly sleeved outside the connecting pipe 81 can reduce the heat loss of the hot water in the connecting pipe 81 and ensure the effectiveness of heat transfer during the transmission process, thereby further improving the energy utilization rate.

[0033] Specifically, the output end of the air outlet cover 4 is connected to the inside of the drying equipment main body 1, the bottom of the drying equipment main body 1 is provided with a discharge port, and the inside of the heat exchange copper pipe 8, the connecting pipe 81 and the metal coil pipe 113 are all filled with water.

[0034] In the embodiment, the inside of the heat exchange copper pipe 8, the connecting pipe 81 and the metal coil pipe 113 are all filled with water, which plays a key role in the process of absorbing heat of water vapor and preheating air as a heat transfer medium, and realizes effective recovery and utilization of heat energy.

[0035] The working principle and use process of the utility model: when using, the rapeseed is placed into the inside of the drying equipment main body 1 through the feed inlet 3, then the hot air is poured into the inside of the drying equipment main body 1 through the air inlet pipe 5 and the air outlet cover 4 to dry the rapeseed by starting the hot air fan 6, and the water vapor generated during drying will come out through the feed inlet 3, by starting the driving motor 9, the driving motor 9 drives the fan wheel 10 to rotate, can the high-temperature steam be inhaled into the air suction pipe 7 inside through the protective cover 2, and heat exchange is carried out to the heat exchange copper pipe 8, after the water inside the heat exchange copper pipe 8 is heat exchanged, by the starting of the circulating water pump 114, the hot water in the heat exchange copper pipe 8 is made into the metal coil pipe 113 inside through the communication pipe 81 and the circulating water pump 114, when the hot air fan 6 works, the air inhaled by the input end of the hot air fan 6 will first enter the inside of the air inlet cylinder 111 and exchange heat with the metal coil pipe 113, because the inhaled air is preheated, therefore can reduce the heating power of the heating element inside the hot air fan 6, make the air can be heated more easily, reduce the consumption of electric energy, at the same time when the inside of the air suction pipe 7 is in the negative pressure state, when the rapeseed is placed into the inside of the feed inlet 3, because of the suction force, still can clean the dust small particles flying when the rapeseed is poured, after the steam inside the air suction pipe 7 is condensed into water droplets, will flow to the end of the air suction pipe 7 together with the dust, strengthen the environmental protection.

[0036] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms, and any skilled person in the art can change or modify the equivalent embodiment with the disclosed technical content. However, any simple modification, equivalent change and modification of the above embodiment without departing from the technical solution of the utility model, according to the technical essence of the utility model, still belongs to the protection scope of the technical solution of the utility model.
