Fig. 1 is a schematic structural diagram of an apparatus for detecting gel according to an embodiment of the present disclosure, please refer to fig. 1, the apparatus includes: the device comprises a bottle body 1, a cover body 2, a first pipe body 3, a stop valve 4, a buffer bottle 5 and a vacuum pump 6; the bottle body 1 is used for containing gel, and the cover body 2 is hermetically arranged on the bottle body 1; the cover body 2 is provided with a first through hole matched with the first pipe body 3, the first end of the first pipe body 3 passes through the first through hole and is inserted into the bottle body 1, and the second end is connected with the stop valve 4; the vacuum pump 6 is used for pumping the gas of the bottle body 1 through the buffer bottle 5, the stop valve 4 and the first pipe 3, and the stop valve 4 is used for sealing the bottle body 1.
The working principle of the device is described in detail below:
the bottle body 1 is used for storing, performing experiments under high temperature and sealed conditions, and visually observing gel, for example, the bottle body 1 can be a transparent glass bottle and has a larger opening, and the bottle body 1 and the cover body 2 can be connected through threads, so that the bottle body is convenient to detach. Specifically, the bottle body 1 may be provided with a lower fastening ring, and the lower fastening ring is fastened on the bottle body 1 and is connected with the cover body 2 through a thread. The cap may be made of type 316 stainless steel in order to maintain rigidity under experimental conditions.
The process of using the device to extract the gas in the bottle body 1 can be as follows: open stop valve 4, make and be in the connected state between bottle 1, first body 3, stop valve 4, buffer bottle 5 and the vacuum pump 6, can be equipped with the manometer on this vacuum pump 6, open this vacuum pump 6, extract the gas in the bottle 1, when the manometer shows that the gas pressure in the bottle 1 is for being less than 0MPa, show that be vacuum state in the bottle 1, close stop valve 4, then close vacuum pump 6, stop bleeding. The space between the buffer bottle 5 and the stop valve 4 is disassembled for the subsequent heating experiment of the gel-filled bottle body 1.
After heating, can open stop valve 4 pressure release earlier, open lid 2 again and take out the gel sample and detect. When the device is cleaned, the residual gel sample is guided into the waste liquid barrel, and the cover body 2, the first pipe body 3 and the stop valve 4 can be cleaned integrally.
Through this vacuum pump 6, buffer bottle 5, stop valve 4 and this first body 3, can be in 1 bottle splendid attire with wait to detect the gel after, extract the gas in this bottle 1, make bottle 1 be in vacuum state, and then heat the device, also make the gel in 1 bottle be in with the stratum state the same high temperature anaerobic environment under, later detect the gel in 1 bottle. After each detection, the device is repeatedly used for extracting the air in the bottle body 1, the detection environment which is the same as the stratum state is kept, the gel is not oxidized by the air in the whole experiment process, and the accuracy of the detection result is improved.
Specifically, the first through hole may be formed concentrically with the cover 2, and the diameter may be set as required, for example, 10 mm. The outer wall of the cover 2 may be provided with anti-slip lines for facilitating screwing, for example, the anti-slip lines may be vertical lines.
The following details the structure and the working principle of each part of the device:
in a possible design, the first end of the first tube 3 is provided with an upward bend. That is, the lower end of the first tube 3 is U-shaped, so that the port of the first end is upward, and the liquid level of the gel does not exceed the port of the first end during the process of adding the gel into the bottle 1, for example, the liquid level can be made 1cm lower than the port of the first end, thereby avoiding the gel from being pumped out of the bottle 1 during the pumping process, and avoiding the loss of the gel or the damage to the vacuum pump 6.
Specifically, the bend may be formed by connecting two right-angle bends, or other structures, which is not limited in this embodiment.
In one possible design, the stop valve 4 is a right angle stop valve 4, the first opening of the right angle stop valve 4 is arranged downwards, and the second opening is arranged horizontally.
