Description

Technical Field

[0001] The invention relates to the technical field of drying, and in particular to an air source heat pump drying system. Background Art

[0002] Traditional drying methods mainly include coal-fired drying, oil-fired drying and electric drying. The above drying methods have single functions and high energy consumption, and cannot adapt well to the current trend of industrial and agricultural industrialization development. Therefore, air-energy drying technology was born. By introducing external ambient air heat to dry the materials in the drying room, the disadvantages of natural drying and traditional energy drying are reduced to a certain extent.

[0003] Announcement No. CN214148760U discloses an air source heat pump dryer. By rotating the knob, the second bevel gear is driven to rotate, and then the first bevel gear is driven to rotate, so that the threaded rod can move up and down, and then cooperate with the lifting device to make the placement plate move up and down smoothly, so as to control the distance between the placement plate and the dryer, so that the user can change the drying degree of the material according to his own needs, realize artificial control of the drying degree and drying speed of the material, set the sliding button and the sliding groove, and realize the clamping of the limit assembly and the threaded rod by controlling the left and right movement of the sliding button on the sliding groove, so as to effectively fix the entire lifting device, and prevent the placement plate from automatically falling due to gravity when it rises to a high place. The operation is simple, time-saving and labor-saving. However, the patent still has the following problems in actual use: Although the air source heat pump dryer controls the distance between the placement plate and the dryer by turning the knob, it is not convenient to adjust the heating speed of the drying room when drying materials, resulting in that when drying materials, the corresponding time and drying temperature cannot be selected according to the characteristics of the materials. For example, the drying temperatures required for silk and cotton and linen in clothes are different, and the appropriate temperature cannot be selected according to the characteristics of the materials, which affects the drying quality of the materials. At the same time, the moisture in the materials cannot be removed quickly, resulting in low drying efficiency.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the air source heat pump drying system can close the opening and closing frame, start the heating wire, and blow the hot air into the wind heating cylinder through the diverter and the diverter pipe through the drying fan, so as to achieve the effect of controlling the temperature, and can control the temperature inside each opening and closing frame according to the characteristics of the material, and can dry materials of different properties. The first drying mechanism can be driven to rotate inside the drying room through the circulating chain, so as to evenly heat the drying room and improve the uniformity of material drying. The specific contents are as follows: 1. By setting up the first drying mechanism, not only can the opening and closing motor be used to drive the bevel gear transmission assembly and the opening and closing threaded rod to rotate, so that the opening and closing threaded sleeve drives the opening and closing connecting rod and the opening and closing frame to move relatively, but also the entire opening and closing frame can be unfolded, so that the dried material can be placed inside the opening and closing frame for drying. At the same time, the rotating motor is started to drive the rotating worm to rotate, and the characteristics of the meshing connection between the rotating worm and the rotating worm wheel are utilized to make the rotating worm wheel drive the meshing toothed disk to rotate. When the meshing toothed disk is meshed with the rotating gear, the rotation of the sector plate can be realized. By adjusting the rotation angle of the sector plate, the heat dissipation inside the opening and closing frame is facilitated. When the internal temperature of the opening and closing frame is higher than the external temperature, the temperature inside the opening and closing frame can be neutralized with the external temperature. At the same time, a temperature detection device is arranged at the bottom of the supporting top plate to monitor the internal temperature of the opening and closing frame. When it is necessary When the internal temperature of the opening and closing frame is increased, the opening and closing frame can be closed, and the heating wire can be started, and the hot air can be blown into the wind heating cylinder through the diverter and the diverter pipe by the drying fan, so as to achieve the effect of controlling the temperature.

By setting up the second drying mechanism, not only can the heating rod be used to heat the interior of the drying room, but also the rotating drying sleeve with holes can be used to achieve uniform heating of the drying room. When it is necessary to quickly discharge the moisture inside the drying room, the ventilation fan can be started. Under the action of wind, the sealing hinge drives the sealing rotating shaft to rotate, which can quickly discharge the moisture inside the drying room. At the same time, the ventilation fan is stopped.

[0022] Working principle: Before using this air source heat pump drying system, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.11 As shown, first, the opening and closing motor 104 is used to drive the bevel gear transmission assembly 105 and the opening and closing threaded rod 106 to rotate, so that the opening and closing threaded sleeve 107 drives the opening and closing connecting rod 108 and the opening and closing frame 109 to move relatively, so that the entire opening and closing frame 109 can be unfolded, so that the dried materials can be placed inside the opening and closing frame 109 for drying. At the same time, the rotating motor 114 is started to drive the rotating worm 115 to rotate, and the rotating worm 115 is engaged with the rotating worm wheel 116. 6 drives the meshing toothed disc 117 to rotate. When the meshing toothed disc 117 is meshed with the rotating gear 110, the fan-shaped plate 111 can be rotated. By adjusting the rotation angle of the fan-shaped plate 111, the heat dissipation inside the opening and closing frame 109 is facilitated. When the internal temperature of the opening and closing frame 109 is higher than the external temperature, the internal temperature of the opening and closing frame 109 can be neutralized with the external temperature. At the same time, a temperature detection device is provided at the bottom of the supporting top plate 101 to monitor the internal temperature of the opening and closing frame 109.

[0023] Secondly, when it is necessary to increase the internal temperature of the opening and closing frame 109, the opening and closing frame 109 can be closed, and the heating wire 122 can be started, and the hot air can be blown into the wind heating cylinder 125 through the diverter 123 and the diverter pipe 124 by the drying fan 121, so as to achieve the effect of controlling the temperature. The temperature inside each opening and closing frame 109 can be controlled individually according to the characteristics of the material, and materials of different properties can be dried. The clothes or materials to be dried are hung on the hook 118, and the rotation of the meshing toothed disc 117 is used to realize the rotation of the hook 118, so as to achieve the effect of uniform heating and improve the quality of material drying. At the same time, the meshing toothed disc 117 can rotate quickly to throw away the moisture on the surface of the material to achieve the effect of rapid brushing. The sliding rollers 129 on both sides of the bottom of the roller bracket 128 can realize the movement of the entire support top plate 101, and the characteristics of the meshing connection between the transmission wheel 126 and the transmission chain 219 can be used to enable the transmission wheel 126 to drive the support top plate 101 to rotate, thereby further improving the material drying effect.

[0024] Finally, the heating rod 206 is used to heat the interior of the drying room 201, and at the same time, the rotating perforated drying sleeve 102 is cooperated to achieve uniform heating of the drying room 201. When it is necessary to quickly discharge the moisture inside the drying room 201, the ventilation fan 209 can be started. Under the action of wind, the sealing hinge 212 drives the sealing rotating shaft 211 to rotate, which can quickly discharge the moisture inside the drying room 201. At the same time, the ventilation fan 209 is stopped, and under the action of gravity, the sealing hinge 212 is rotated to a vertical direction, which can close the ventilation bracket 207 to avoid temperature loss inside the drying room 201, thereby affecting the drying room 201. Drying effect, the spun water can be discharged through the drain valve 203, and the circulating motor 213 is started to drive the circulating active sprocket 214 to rotate. The circulating chain 215 can be rotated by utilizing the meshing connection between the circulating active sprocket 214, the circulating chain 215 and the circulating driven sprocket 216. The circulating chain 215 is limited by the chain limiting bracket 217 to avoid the phenomenon of the circulating active sprocket 214 and the circulating driven sprocket 216 being disengaged. The circulating chain 215 can drive the first drying mechanism 1 to rotate inside the drying room 201, thereby uniformly heating the drying room 201 and improving the uniformity of material drying.
