detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, the melon shell drying device described in the utility model includes a drying chamber 1, a partition 2, a blast pipe 6, a first blower 41, a second blower 42, a third blower 43, an exhaust Pipe 8, belt conveyor 3;

The partition 2 is installed in the drying chamber 1, and the drying chamber 1 is divided into a first drying chamber 11, a second drying chamber 12, and a third drying chamber 13; the first drying chamber 11, The bottoms of the second drying chamber 12 and the third drying chamber 13 are all provided with blowing outlets, and the tops are all provided with air outlets; the air outlets communicate with the exhaust pipe 8;

The air outlet of the first air blower 41 communicates with the air outlet at the bottom of the first drying chamber 11 through the air blast pipe 6; There is a first heating device 51; the air outlet of the second air blower 42 communicates with the air outlet at the bottom of the second drying chamber 12 through the air blast pipe 6; between the second air blower 42 and the second drying chamber 12 The air blast pipe 6 is provided with a second heating device 52; the air outlet of the third blower 43 communicates with the air blast at the bottom of the third drying chamber 13 through the air blast pipe 6; The blast pipe 6 between the three drying chambers 13 is provided with a third heating device 53;

The belt conveyor has a conveyor belt 31, and the conveyor belt 31 has air holes; the belt conveyor 3 is arranged below the drying chamber 1, and the conveyor belt 31 of the belt conveyor is positioned above the tuyere, so The airflow in the tuyeres passes through the ventilation holes on the conveyor belt 31; the conveyor belt 31 runs through from one end of the drying chamber 1 to the other end; the end of the conveyor belt 31 located at the first drying chamber 11 is the feeding end , and the other end is the discharge end.

The first heating device 51 , the second heating device 52 and the third heating device 53 can all be realized by using heat exchangers.

During the working process of the melon shell drying device:

First melon shells are sent to the feeding end of the conveyor belt 31, the belt conveyor 3 is started, and the belt conveyor 3 sends the melon shells to the first drying chamber 11; the belt conveyor 3 is braked. At this time, start the first blower 41 and the first heating device 51 so that the first blower 41 blows hot air to the bottom of the first drying chamber 11 , and the temperature of the hot air can be adjusted by controlling the first heating device 51 . Since the conveyor belt 31 has air holes; the belt conveyor 3 is arranged below the drying chamber 1, and the conveyor belt 31 of the belt conveyor 3 is positioned above the tuyeres, the airflow in the tuyere passes through the Air vents on the belt 31; therefore hot air can pass through the conveyor belt 31 to dry the melon shells on the conveyor belt 31. After drying to a certain period of time, after most of the moisture in the melon shell is evaporated, restart the belt conveyor 3 and send the melon shell into the second drying chamber 12, then brake the belt conveyor 3, and start the second air blower 42 and the second heating device 52 make the second blower 42 blow hot air to the bottom of the second drying chamber 12 , and the temperature of the hot air in the second drying chamber 12 can be adjusted by controlling the second heating device 52 .
