[0028] Depend on Figure 1 , Figure 2 and Figure 3 As shown, an energy-saving continuous dryer with waste heat recovery includes a dryer body 1, a drying element 2, an air supply pipe 3 and a collecting mechanism 4. The drying element 2 is fixedly installed inside the dryer body 1, and the collecting mechanism 4 is fixedly installed on the side of the dryer body 1. The air supply pipe 3 is fixedly installed on the top of the collecting mechanism 4, and the separation mechanism 5 is fixedly installed at the end of the air supply pipe 3. The separation mechanism 5 includes a connecting pipe 51, a separation bin 52 and a separation filter element 53.

[0029] During use, the tea leaves on the surface of the drying element 2 are quickly dried by using the dryer body 1, and then the hot air inside the dryer body 1 is stably extracted by using the collecting mechanism 4, and then the hot air is input into the separation mechanism 5 by using the air supply pipe 3 to filter the moisture in the hot air. During use, the hot air to be filtered is input into the separation bin 52 by using the connecting pipe 51 and the air supply pipe 3, and then the hot air entering the separation bin 52 is filtered by using multiple sets of separation filter elements 53, and the moisture in the hot air is screened and separated to prevent water vapor from re-entering the equipment with the hot air and affecting the normal drying operation inside the equipment.

[0030] By the attached Figure 4 As shown, in this embodiment, the separation mechanism 5 also includes a flow groove 54, a water-absorbing sponge 55 and a sealing plate 56. The flow groove 54 is opened at the bottom end of the separation bin 52, the water-absorbing sponge 55 is arranged inside the flow groove 54, and the sealing plate 56 is fixedly installed on the side of the separation bin 52. During use, through the use of the flow groove 54, when the water filtered by the separation filter element 53 is completed, the water will flow along the inner wall of the separation bin 52 to the lower end and directly enter the bottom of the flow groove 54. Through the use of the water-absorbing sponge 55, the water is absorbed to complete the collection of water. The use of the sealing plate 56 makes it easy to replace the water-absorbing sponge 55 while ensuring the internal sealing of the separation bin 52.

[0031] By the attached Figure 3 As shown, in this embodiment, the collecting mechanism 4 includes a bonding plate 41, a connecting pipe 42, a receiving pipe 43, an extractor 44, a feeding pipe 45 and a connecting piece 46.

The conduction plate 63 is fixedly connected to the fixing member 62. During use, the recovered hot air is input into the conduction plate 63 through the use of the matching pipe 61 and the fixing member 62, and then the hot air is input into the dryer body 1 with the cooperation of the conduction plate 63, so as to realize the recovery and utilization of the hot air and ensure the stability of the equipment during use.

The dryer body 1 is connected with the shell heating groove 65 through the flow holes 66. In use, the hot air output by the connecting pipe 51 is diverted by the use of the input pipe 64, and part of the hot air will not enter the dryer body 1, but enter the shell heating groove 65 on the side wall of the dryer body 1 with the cooperation of the input pipe 64, so as to heat the shell of the dryer body 1 itself, which can effectively solve the problem that the heat inside the dryer body 1 is gradually lost due to the conduction of the shell of the dryer body 1. The opening of the flow hole 66 allows the hot air inside the shell heating groove 65 to follow the hot air inside the dryer body 1 to re-enter the bonding plate 41, so as to realize the recycling of heat.
