Description
Technical Field
[0001] The utility model relates to the technical field of drying rooms, in particular to a drying room with a waste heat recovery mechanism. Background Art
[0002] A drying room is a facility used to dry agricultural products, food, medicinal materials, wood and other items. It can achieve rapid and uniform drying in a relatively stable environment, thereby improving product quality and reducing storage costs.
[0003] Existing drying rooms generally use hot air to dry materials. The air during the drying process will be directly discharged, resulting in waste of excess heat in the air.
[0004] In order to overcome the above-mentioned defects, a Chinese patent of the prior art (publication number: CN207613166U) discloses a waste heat recovery drying room, which heats the inhaled air through an air energy heat pump, and then draws the hot air into the drying box through a circulating fan to dry the fruits and vegetables in the drying box. The cold air that has been dried and cooled is circulated back to the heat exchange chamber for circulating heating. Since the cold air circulated back to the heat exchange chamber has a certain residual temperature, it can reduce the energy consumed by heat exchange, which is more energy-saving and environmentally friendly.
[0005] The above-mentioned prior art heats the air by circulating it inside the drying room. Since the cold air circulates back into the heat exchange chamber with a certain residual temperature, the energy consumed by the heat exchange is reduced. However, in actual use, when the hot air circulates inside the drying room, the moisture contained in the hot air will increase. The moisture in the circulating hot air will cause the drying efficiency to decrease. Utility Model Content

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a drying room with a waste heat recovery mechanism, comprising a drying room placed on the ground, a sealed door hinged on the front side of the drying room, and an air heat pump placed on the ground at the rear side of the drying room;

The circulation pipe has a U-shaped structure, and a drainage pipe is fixedly connected to the middle of the bottom of the circulation pipe. A partition is fixedly connected to the top of the inner side of the drying room, and a drying fan is fixedly connected to the inside of the drying room and is distributed vertically with the partition, and the drying fans are distributed in a matrix inside the drying room.
[0009] Preferably, the connecting pipe includes an air duct fixedly connected to the air heat pump, and the end of the air duct away from the air heat pump is fixedly connected to the drying room, the end of the air duct away from the air heat pump is fixedly connected to a wind shield, and the outside of the wind shield is provided with exhaust holes distributed in a circular shape.
[0010] Preferably, a mounting plate is fixedly connected to the top of the circulation pipe, and heat dissipation fans distributed in a matrix are fixedly connected to the top of the mounting plate, and there is a gap between the top of the circulation pipe and the mounting plate.
[0011] Preferably, mounting holes distributed in a matrix are provided on both sides of the middle of the circulation pipe, and a water collecting trough is provided at the bottom of the middle of the circulation pipe, and the bottom of the water collecting trough is fixedly connected to the drainage pipe.
[0012] Preferably, a condenser tube distributed in an S-shaped structure is fixedly connected to the middle of the circulation tube, and the condenser tube is set to a multi-layer structure, and a condenser sheet is fixedly connected to the outside of each horizontally distributed condenser tube.
[0013] Preferably, both ends of the condenser tube extend to the outside of the circulation tube through the mounting holes, and both ends of the condenser tube are fixedly connected with heat dissipation tubes, the heat dissipation tubes are set to an S-shaped structure, and the heat dissipation tubes are located between the mounting plate and the top of the circulation tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] The drying room with waste heat recovery mechanism cools down the radiator through multiple heat dissipation fans, so that the heat of the heat dissipation pipe is taken away by the radiator, and the heat dissipation pipe takes away the heat of the condenser pipe and the condenser sheet. At this time, the condenser sheet will be in a lower temperature state. At this time, the hot air contacts the condenser sheet, so that the moisture in the hot air will condense on the condenser sheet. At the same time, the water will drip into the water collection tank and be discharged through the drain pipe to achieve a dehumidification effect.
[0017] Furthermore, the air introduced into the air heat pump through the circulation pipe will still have residual heat, and the air heat pump will reheat the air with residual heat, thereby achieving the effect of recovering the residual heat of the hot air inside the drying room;
[0018] Furthermore, during the process of discharging the hot air inside the windshield, the hot air is evenly discharged through the exhaust holes, so that the hot air is evenly distributed inside the drying room, thereby improving the drying efficiency of the materials.

[0037] Example two:
[0038] Based on example one, the specific working principle is as follows:
[0039] First, open the sealing door 2 to make the inside of the drying room 1 an open environment, and then place the materials in the drying room 1. At this time, the materials will be located at the bottom of the partition plate 8 and the front side of the drying fan 7. After the materials are placed in the drying room 1, the sealing door 2 is closed, and the air heat pump 3 is started to guide hot air into the drying room 1 through the connecting pipe 4 to dry the materials.
[0040] In the process of drying the material, hot air enters the inside of the drying room 1 from the connecting pipe 4, and the multiple drying fans 7 in the inside of the drying room 1 will be started, thereby guiding the hot air introduced by the connecting pipe 4 to the bottom of the partition plate 8, so as to dry the material in the bottom of the partition plate 8 and the front side of the drying fan 7; when the hot air flows in the inside of the drying room 1, it will flow between the partition plate 8 and the front side of the drying room 1 through the guiding of the drying fan 7, and then re-enters between the rear side of the drying room 1 and the drying fan 7 after flowing between the top of the drying room 1 and the partition plate 8, thereby circulating the hot air in the inside of the drying room 1, improving the drying efficiency of the hot air on the material;
[0041] When the air heat pump 3 guides the hot air into the inside of the drying room 1 through the connecting pipe 4, the hot air will enter the inside of the wind deflector 402 through the air guide pipe 401, and the hot air in the inside of the wind deflector 402 will be discharged into the inside of the drying room 1 through the air outlet hole 403; since the air outlet hole 403 is evenly distributed on the outside of the wind deflector 402, the hot air is uniformly discharged through the air outlet hole 403 during the discharging process of the hot air in the inside of the wind deflector 402, so that the hot air is uniformly distributed in the inside of the drying room 1, improving the drying efficiency of the material;
[0042] When the air heat pump 3 sends the hot air into the inside of the drying room 1, it will cause the air pressure in the inside of the drying room 1 to increase, and at this time the air in the inside of the drying room 1 will be re-introduced into the inside of the air heat pump 3 through the circulating pipe 5; the air introduced into the inside of the air heat pump 3 still has residual heat, and the air heat pump 3 performs secondary heating on the air with residual heat, thereby achieving the effect of recycling the residual heat of the hot air in the inside of the drying room 1;
[0043] When the hot air flows in the inside of the circulating pipe 5, the hot air will pass through the middle section of the circulating pipe 5, and the dehumidification structure in the middle section of the circulating pipe 5 will dry the air; when the air flows in the middle section of the circulating pipe 5, the air will be in contact with multiple condensation pieces 14, the condensation pieces 14 are fixed through the condensation pipe 13, and the condensation pipe 13 and the heat dissipation pipe 15 are in communication with each other, the cooling row 16 is cooled through multiple heat dissipation fans 10, thereby taking away the heat of the heat dissipation pipe 15 through the cooling row 16, so that the heat dissipation pipe 15 takes away the heat of the condensation pipe 13 and the condensation pieces 14; at this time, the condensation pieces 14 will be in a lower temperature state, and when the hot air contacts the condensation pieces 14, the moisture in the hot air will condense on the condensation pieces 14, and the water will drop into the water collecting tank 12 and be discharged through the drain pipe 6, thereby achieving the dehumidification effect.
