The air guide hose 7 is provided with a valve 8. A screw cap 9 is provided at the end of the hose 7, and a through hole is opened at the screw cap 9 to fix a bearing 10. The end of the air guide hose 7 is fixed to the inner ring position of the bearing 10. A humidity sensor 11 is fixedly installed below the screw cap 9. An externally threaded sealed hollow sleeve 13 is fixedly installed at the lower part of the humidity sensor 11. The externally threaded sealed hollow sleeve 13 is threadedly connected and fixed to the inner glass container 3. The sensing needle 12 of the humidity sensor 11 is extended and set. An air guide channel 14 corresponding to the air guide hose 7 is opened through the humidity sensor 11 and the externally threaded sealed hollow sleeve 13. A water pipe 15 is connected to the other side of the seal at the top of the outer glass cover 2 and the inner glass container 3. The top of the inner glass container 3 and the water pipe 15 are flush and a rubber sheet joint 16 is placed.

[0038] Specifically, such as Figure 1 and Figure 2As shown, the outer glass cover 2 includes a spherical outer cover 201, an annular base 202 and a sealing body 203. The bottom of the spherical outer cover 201 is integrally connected to the annular base 202, and the annular base 202 is fixed to the heating base 1. The top of the spherical outer cover 201 is integrally connected to the sealing body 203. The inner glass container 3 includes an aging and placement inner container 301, a material tube 302 and an internal threaded body 303. The top of the aging and placement inner container 301 is integrally connected to the material tube 302. The lower part of the sealing body 203 is integrally connected to the aging and placement inner container 301 to form a seal. The upper part of the material tube 302 is provided with an internal threaded body 303. The integral connection facilitates uniform heating and external observation.

[0039] Specifically, such as Figure 2 As shown, the outer side of the rotary cover 9 is provided with anti-slip grooves to facilitate rotation.

[0040] Specifically, such as Figure 2 As shown, a gap is formed between the external thread sealing hollow sleeve 13 and the upper portion of the humidity sensor 11. The gap forms a ring platform that can be pressed on the rubber sheet connection body 16 to improve the sealing performance.

[0041] Specifically, such as Figure 2 As shown, a display screen 17 is provided on the upper portion of the humidity sensor 11 for convenient observation of the humidity value.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, a bucket body is provided on the upper part of the water pipe 15, and the rubber sheet joint 16 includes a rubber circular cover sheet 1601, a rubber ring sheet 1602 and a rubber plug column 1603. The rubber circular cover sheet 1601 is integrally connected to the rubber ring sheet 1602, and the rubber ring sheet 1602 covers the edge of the material pipe 302. The rubber circular cover sheet 1601 covers the bucket body, and the rubber plug column 1603 is fixedly installed on the rubber circular cover sheet 1601. The rubber plug column 1603 is sealed in the water pipe 15 to play a double sealing role.

[0043] Working principle:

[0044] When in use, open the rubber sheet joint 16, then inject water from the bucket position of the water pipe 15, the water fills the interlayer 4, cover the rubber sheet joint 16, and plug the rubber plug 1603 into the water pipe 15 to seal its opening. At this time, the rubber ring piece 1602 is at the opening position of the material pipe 302 and acts as a sealing gasket. Cover the external thread sealing hollow sleeve 13, the external thread sealing hollow sleeve 13 and the internal thread body 303 are tightened and fixed. The distance difference between the humidity sensor 11 and the external thread sealing hollow sleeve 13 forms a ring platform, and the ring platform is pressed on the rubber ring piece 1602. In this way, the external thread sealing hollow sleeve 13 seals the material pipe 302, and the heating is started. The base 1 and the electric heating head 6 generate heat to heat the water. After the water is heated to the desired constant temperature, the external thread sealed hollow sleeve 13 is opened, and the silica aerogel powder and the desired aging agent are put into the aging container 301. Since the aging container 301 is wrapped by water, the temperature inside the aging container 301 is relatively uniform, and there is no large temperature difference at different places. After the water is put in, the external thread sealed hollow sleeve 13 is immediately sealed again. The temperature sensor 5 detects the change in water temperature, and the electric heating head 6 makes corresponding heating adjustments to maintain the temperature inside the aging container 301 constant. Constant temperature control is a prior art and will not be described in detail.

[0045] The sensing needle 12 extends to the lower part of the material tube 302 to detect the humidity in the aging container 301. The display screen 17 displays the humidity value in the aging container 301. If the humidity value is low, the valve 8 is opened, and the water vapor generated by the hot water in the interlayer 4 enters the air guide channel 14 through the air guide hose 7. The air guide channel 14 is connected to the aging container 301. Because the aging container 301 itself has a certain heat insulation effect, there is a temperature difference between the interlayer 4 and the aging container 301. In this way, water vapor can move smoothly into the aging container 301, and the humidity in the aging container 301 increases. After the humidity value reaches the required aging value, the valve 8 is closed.

[0046] After standing for a period of aging, the rubber round cover 1601 is pulled out, the entire device is turned upside down, the water in the interlayer 4 is poured out from the water pipe 15, and then the external thread sealing hollow sleeve 13 is opened to pour out the silica aerogel powder.

[0047] The present application also discloses a method for using a silica aerogel powder static aging device, which adopts the following technical solution:

[0048] The steps are as follows:

[0049] (1) Inject water from the water pipe 15, the water enters the interlayer 4, covers the rubber sheet joint 16, and tightens the external thread sealing hollow sleeve 13 and the material pipe 302;

[0050] (2) The heating base 1 is started, and the electric heating head 6 heats the water, and the water wraps the aging container 301. Since the aging container 301 is coated with a heat-insulating coating, there is a temperature difference between the temperature inside the aging container 301 and the water temperature, and a uniform heat environment is formed inside the aging container 301;

[0051] (3) When the water temperature is appropriate, open the external thread sealing hollow sleeve 13, put the silica aerogel powder and aging agent into the inner glass container 3, place the rubber sheet joint 16 again, tighten the external thread sealing hollow sleeve 13, and place the aging agent inside the inner container 301 to form a constant temperature sealed environment;

[0052] (4) Open valve 8, and the water vapor in interlayer 4 flows from air guide hose 7 along air guide channel 14 into aging container 301. The sensing needle 12 of humidity sensor 11 detects the humidity in aging container 301 in real time. When the humidity environment meets the standard, close valve 8.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
