Embodiment 1

[0044] Step 1, weigh 100kg tetrafluoroborate wet material, put the wet material into the drying container, open the rotary seat to drive the drying container to rotate, and the rotation speed is 15r / min;

[0045] Step 2. After the drying container rotates stably, start the vacuum device, set the vacuum degree parameter to -0.09MPa, maintain the vacuum degree for 30 minutes, and turn off the vacuum device after continuous vacuuming for 30 minutes;

[0046] Step 3: Turn on the blowing device and blow gas into the drying container to replace the vacuum. When the blowing device is in operation, the gas pressure is 0.03MPa, and the blowing gas is nitrogen with a moisture content of 50ppm. Stop when the pressure value of the drying container is 0.003 MPa. Blow;

[0047] Step 4, repeat step 2 and step 3, repeat the replacement operation 3 times, check the drying of the material, find that the material has not been dried, repeat the operation of step 2 and step 3 3 times, check that t...

Embodiment 2

[0051] Step 1, weigh 200kg tetrafluoroborate wet material, put the wet material into the drying container, open the rotary seat to drive the drying container to rotate, and the rotation speed is 17r / min;

[0052] Step 2. After the drying container rotates stably, start the vacuum device, set the vacuum degree parameter to -0.08MPa, maintain the vacuum degree for 35 minutes, and turn off the vacuum device after continuous vacuuming for 35 minutes;

[0053] Step 3: Turn on the blowing device and blow gas into the drying container to replace the vacuum. When the blowing device is in operation, the gas pressure is 0.05MPa, and the blown gas is helium with a moisture content of 80ppm. After the drying container is inflated, the pressure value is 0.001 MPa. stop blowing;

[0054] Step 4, repeat step 2 and step 3, repeat the replacement operation 3 times, check the drying of the material, find that the material has not been dried, repeat the operation of step 2 and step 3 3 times, ch...

Embodiment 3

[0058] Step 1, weigh 100kg tetrafluoroborate wet material, put the wet material into the drying container, open the rotary seat to drive the drying container to rotate, and the rotation speed is 20r / min;

[0059] Step 2. After the drying container rotates stably, start the vacuum device, set the vacuum degree parameter to -0.1MPa, maintain the vacuum degree for 40 minutes, and turn off the vacuum device after continuous vacuuming for 40 minutes;

[0060] Step 3: Turn on the blowing device to blow gas into the drying container to replace the vacuum. When the blowing device is in operation, the gas pressure is 0.06MPa, and the blowing gas is nitrogen with a moisture content of 60ppm. Stop when the pressure value of the drying container is 0.002 MPa. Blow;

[0061] Step 4, repeat step 2 and step 3, repeat the replacement operation 3 times, check the drying of the material, find that the material has not been dried, repeat the operation of step 2 and step 3 3 times, check that the...

Abstract

The invention discloses a drying method and drying device of fluorine-containing borate. The drying method comprises the following processing steps that 1, a drying container is fed, and a rotating seat controls the drying container to overturn and rotate; 2, a vacuumizing device vacuumizes the drying container, and when the maintaining-preset vacuum parameter reaches the preset vacuum maintenancetime, the vacuumizing device stops operating; 3, a blowing device blows air to the interior of the drying container, and when the preset pressure value of the drying container after inflating reachesthe preset value, the blowing device stops blowing the air; and 4, the operation of the steps of 2 and 3 is repeated until the moisture content of the fluorine-containing borate meets the productionrequirements. On the other hand, the invention further provides a drying device with the simple structure and convenient operation. The drying method and the drying device of fluorine-containing borate have the advantages of being high in efficiency, saving in energy, low in cost, high in drying efficiency, simple in structure, convenient to operate and the like.

Description

technical field [0001] The invention relates to the technical field of vacuum drying, in particular to a drying method and a drying device for borate containing fluorine. Background technique [0002] With the development of modern society and the enhancement of people's awareness of environmental protection, supercapacitors are gradually replacing lead-acid batteries and nickel-hydrogen batteries, developing into the main alternative power source in the 21st century. For large-scale power supercapacitors used in supercapacitors, especially electric vehicles and energy storage devices, the factors that limit their further application are mainly the cycle performance and safety performance of batteries, and one of the main factors affecting battery performance is moisture in it. [0003] As one of the most promising energy storage devices in the field of new energy, supercapacitors have become one of the research hotspots in the United States, Japan, South Korea, Russia and ...
