Description

Technical Field

[0001] The utility model relates to the field of drying machines, in particular to a heat exchange device for drying machines. Background Art

[0002] Dryer is a device that removes moisture from materials by heating and ventilation. By removing moisture from materials, it can prevent mold, rot and other quality problems, ensure product quality and stability. The drying process can significantly shorten the drying time of materials and improve production efficiency. Compared with natural drying, mechanical drying is faster and is not affected by weather. The use of dryers can reduce the space required for stacking materials, and also reduce the dependence on manual drying, saving human resources.

[0003] When the dryer dries the material, the material is fed into the dryer through the feeding port, and then the dryer is started, so that the blower of the dryer sends the outside air to the heater. The heater can effectively transfer the heat energy to the air in the dryer, and then the hot air is introduced into the dryer to exchange heat with the material. Since the hot air outlet position of the heater is fixed, the hot air is continuously output at the same position, which can easily cause the problem of over-high temperature in some areas. Therefore, we propose a heat exchange device for the dryer. Utility Model Content

[0004] The utility model aims to provide a heat exchange device for a dryer to solve the problem that the hot air outlet position of the dryer heater proposed in the above background technology is fixed, so that the hot air is continuously output at the same position, which easily causes the temperature in some areas to be too high.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat exchange device for a dryer, comprising a dryer body and a heater, one end of the dryer body is sequentially provided with a feeding port and an exhaust port, and the other end of the dryer body is sequentially provided with a blower and a heater, a discharge port and a drive assembly are sequentially provided on the lower side of the dryer body, and the drive assembly comprises a transmission gear ring, a gear and a drive motor, the air outlet of the heater is movably connected to a diverter plate through a bearing, and a fixed gear ring is fixed to the outer side of the diverter plate, the fixed gear ring is connected to a toothed disc, and one side of the toothed disc is fixed to a connecting motor, and a storage battery is installed on the side of the dryer body close to the connecting motor.

[0006] Preferably, a mesh cover is provided on one side of the dryer body close to the discharge port, and a connecting cover is fixed to the outer side of the mesh cover.

[0007] Preferably, the inner side of the connecting cover is fixed to the connecting spring, and the connecting cover is connected to the dryer body.

[0008] Preferably, the fixed gear ring is meshingly connected to the gear disc.

[0009] Preferably, the air inlet of the blower is provided with a placement groove and a docking groove in sequence, and the docking groove is connected to the docking ring plate.

[0010] Preferably, the placement groove is connected to the connection pad, and the connection pad is fixed to the docking ring plate.

[0011] Preferably, a filter plate is fixed to the outer side of the docking ring plate, and the filter plate is connected to the air inlet of the blower via connecting bolts.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The heat exchange device for a dryer proposed by the utility model is as follows: the connection motor is started so that the diverter plate can rotate while diverting the hot air, so that the high-temperature hot air can be evenly delivered to different parts of the dryer body to avoid the occurrence of excessively high or low temperature areas, thereby ensuring that the material is evenly heated during the drying process, and the filter plate and the air inlet of the blower are restricted together by connecting bolts and nuts, so that a sealing state is formed between the connecting pad and the mounting groove, so that the filter plate can prevent dust and waste from entering the blower, and the heater of the dryer is not easily affected by dust and waste.

[0014] 1. The dryer uses a heat exchange device. When the dryer body dries the material, the material is fed into the dryer body through the feeding port, and then the dryer body is started. At this time, the material rolls to the mesh cover. The installed mesh cover can prevent the material from approaching the diverter plate. At the same time, the blower of the dryer sends the outside air to the heater, and then the hot air is introduced into the dryer body to contact with the material for heat exchange. At this time, the connecting motor is started again, so that the diverter plate can rotate while diverting the hot air, so that the high-temperature hot air can be evenly fed into different parts of the dryer body to avoid the appearance of too high or too low temperature areas, thereby ensuring that the material is evenly heated during the drying process;

[0015] 2. The heat exchange device for the dryer is used. When the main body of the dryer is in operation, the docking ring plate is docked with the docking groove. At this time, the filter plate and the air inlet of the blower are restricted together by using connecting bolts and nuts, so that the filter plate pushes the connecting pad to dock with the mounting groove, so that a sealing state is formed between the connecting pad and the mounting groove, so that the filter plate can prevent dust and waste from entering the blower, and the heater of the dryer is not easily affected by dust and waste.

[0025] In specific implementation, according to Figure 1-Figure 3 When the dryer body 1 dries the material, the material is fed into the dryer body 1 through the feeding port 101, and then the dryer body 1 is started, and the driving component 106 drives the dryer body 1 to rotate. At this time, the material rolls to the mesh cover 205. The installed mesh cover 205 can prevent the material from approaching the diverter plate 2, and the connecting cover 206 is made of high-temperature resistant rubber material with a certain deformation ability, so that the mesh cover 205 can buffer the impact force of the rolling material, and the fixed connecting spring 207 can assist the mesh cover 205 to return to its original position after buffering. At the same time, the blower 103 of the dryer sends the outside air to the heater 104, and the heater 104 can effectively transfer the heat energy to the air in the dryer body 1, and then guide the hot air to the air outlet 106. The air enters the dryer body 1 and contacts with the material for heat exchange.

[0026] Embodiment 2

[0027] Based on Example 1, please refer to Figure 1 , Figure 4 and Figure 5 The air inlet of the blower 103 is sequentially provided with a placement groove 3 and a docking groove 301, and the docking groove 301 is connected to the docking ring plate 302, the placement groove 3 is connected to the connection pad 303, and the connection pad 303 is fixed to the docking ring plate 302, a filter plate 304 is fixed to the outer side of the docking ring plate 302, and the filter plate 304 is connected to the air inlet of the blower 103 through a connecting bolt (305), the cross-sectional size of the docking groove 301 matches the cross-sectional size of the docking ring plate 302, the connecting pad 303 is made of rubber, and the placement groove 3 and the connecting pad 303 are squeezed.

[0028] In specific implementation, according to Figure 1 , Figure 4 and Figure 5 When the dryer body 1 is in operation, the docking ring plate 302 is docked with the docking groove 301. The cross-sectional size of the docking groove 301 matches the cross-sectional size of the docking ring plate 302, so that the docking ring plate 302 is not easy to shake inside the docking groove 301. At this time, the filter plate 304 is restricted together with the air inlet of the blower 103 by using the connecting bolts 305 and nuts. At this time, the filter plate 304 is squeezed so that the filter plate 304 pushes the connecting pad 303 to dock with the mounting groove 3. The connecting pad 303 is made of rubber material with a certain deformation ability, and the mounting groove 3 is squeezed with the connecting pad 303, so that the connecting pad 303 and the mounting groove 3 are sealed, so that the filter plate 304 can prevent dust and waste from entering the blower 103, so that the heater 104 of the dryer is not easily affected by dust and waste.

[0029] In actual use, the heater 104 can effectively transfer heat energy to the air in the dryer body 1, and then guide the hot air into the dryer body 1 to contact with the material for heat exchange. At this time, the connecting motor 203 is started again to make the fixed gear ring 201 drive the diverter plate 2 to rotate, so that the diverter plate 2 can divert the hot air while rotating, so that the high-temperature hot air can be evenly delivered to different parts of the dryer body 1, which helps to improve the temperature uniformity in the dryer body 1 and avoid the occurrence of too high or too low temperature areas, thereby ensuring that the material is evenly heated during the drying process. The filter plate 304 is restricted to the air inlet of the blower 103 by using connecting bolts 305 and nuts.
