Problems solved by technology

[0002] The traditional drying method firstly needs to dehydrate the material through a centrifuge and then put it into a double-cone dryer for heating and drying. On the one hand, the labor intensity of manual processing is increased. On the other hand, the drying time is long and the drying efficiency is low. High energy consumption and high drying cost

Embodiment 1

[0032] The first step: put the material into the double cone dryer;

[0033] Step 2: Connect one end of the feed port of the double-cone dryer to compressed air, and connect the suction filter part to a vacuum pump to exhaust and dehumidify the materials in the tank. After running for 0.5 hours, remove the compressed air and vacuum pump , so that the moisture content of the material is below 15%;

[0034] Step 3: Control the vacuum degree in the double-cone dryer to -0.09Mpa, and gradually increase the temperature. The initial temperature is 30°C, and it rises to 60°C after 1h, and then rises to 80°C after 1h, and then After 1 hour, the temperature was raised to 120°C and operated for 1 hour; at the same time, the double-cone dryer rotated forward and reverse alternately at a speed of 3 r / min, and operated for 5 minutes respectively. ;

[0035] Step 4: Control the vacuum degree of the double-cone dryer to -0.09Mpa, the temperature at 50°C, and the drying time for 3 hours, so...

Embodiment 2

[0037] The first step: put the material into the double cone dryer;

[0038] Step 2: Connect one end of the feed port of the double-cone dryer to compressed air, and connect the suction filter part to a vacuum pump to exhaust and dehumidify the material in the tank. After running for 2 hours, remove the compressed air and the vacuum pump. So that the moisture content of the material is below 15%;

[0039] Step 3: Control the vacuum degree in the double-cone dryer to -0.098Mpa, and gradually increase the temperature. The initial temperature is 30°C, and it rises to 60°C after 2 hours, and then rises to 80°C after 2 hours, and then After 2 hours, the temperature was raised to 120°C and operated for 2 hours; at the same time, the double-cone dryer rotated forward and reverse alternately at a speed of 5 r / min, and operated for 15 minutes respectively. ;

[0040] Step 4: Control the vacuum degree of the double-cone dryer to -0.098Mpa, the temperature at 60°C, and the drying time ...

Embodiment 3

[0043] The first step: put the material into the double cone dryer;

[0044] Step 2: Connect one end of the feed port of the double-cone dryer to compressed air, connect the suction filter part to a vacuum pump, and dehumidify the material in the tank, and remove the compressed air and vacuum pump after running for 1 hour. So that the moisture content of the material is below 15%;

[0045] Step 3: Control the vacuum degree in the double-cone dryer to -0.095Mpa, and gradually increase the temperature. The initial temperature is 30°C, and it rises to 60°C after 1.5h, and then rises to 80°C after 1.5h. After another 1.5h, the temperature rises to 120°C and runs for 1.5h; at the same time, the double-cone dryer rotates forward and reverse alternately at a speed of 4r / min, and runs for 10 minutes respectively. ;

[0046] Step 4: Control the vacuum degree of the double-cone dryer to -0.095Mpa, the temperature at 55°C, and the drying time for 2 hours, so that the moisture content o...

Abstract

The invention discloses a drying method for a double-cone dryer. The drying method for the double-cone dryer comprises the following specific steps: (1) materials are put in the double-cone dryer; (2)one end of a feed port of the double-cone dryer is connected into compressed air; a suction filtration part is connected into a vacuumizing machine for air extraction and dehumidification of materials in a tank; after operation by 0.5-2 h, compressed air and the vacuumizing machine are removed, so that the material water content is below 15%; (3) the vacuum degree in the double-cone dryer is controlled to be higher than -0.09 Mpa; the temperature is 30-150 DEG C; and the double-cone dryer is operated by 4-8 h, and is rotated at intervals; and (4) the vacuum degree of the double-cone dryer iscontrolled to be higher than -0.09 Mpa; the temperature is 50-60 DEG C; the drying time is 1.5-3 h; and the material water content is below 0.5%.

Description

technical field [0001] The invention relates to a drying method, in particular to a drying method used in a double-cone dryer. Background technique [0002] The traditional drying method firstly needs to dehydrate the material through a centrifuge and then put it into a double-cone dryer for heating and drying.
