It is mainly used as an intermediate for medicine and pesticides. Its vapor can form an explosive mixture with air, and it is very easy to burn and explode when exposed to open flames and high heat. It reacts violently with oxidants. It decomposes and releases highly toxic fumes when exposed to high heat. It is corrosive. If it is exposed to high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion. Due to its special danger, a storage device is required to store it.

[0022] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-3 The present invention provides a technical solution: a trifluoroethyl acetate sealing detection device and detection method, comprising a box body 1, a cover body 2 and a sealing detection system, two sets of slide rails 10 are fixed inside the box body 1, each set of slide rails 10 is provided with two, respectively arranged on the left and right sides of the box body 1, a bottom plate (not shown in the figure) is fixedly connected between the four sets of slide rails 10, a storage cylinder 8 is arranged above the bottom plate, and a feeding port 9 is opened on the top of the storage cylinder 8 for pouring trifluoroethyl acetate into the storage cylinder 8, a linear drive is arranged between each set of slide rails 10 and the bottom plate, and the bottom plate can be slid up and down inside the box body 1 through the linear drive, thereby driving the storage cylinder 8 to slide up and down inside the box body 1.

[0024] The cover body 2 is arranged above the box body 1 and can cover the box body 1. A sealing layer 12 is arranged at the bottom of the cover body 2. The sealing layer 12 is made of rubber. When the cover body 2 covers the box body 1, the top of the box body 1 is sealed through the sealing layer 12 to ensure the sealing of the box body 1 and the cover body 2.

[0025] A controller 7 is provided on one side of the box body 1 , and a voice alarm device is provided in the controller 7 .

[0026] A first pipe 3 and a second pipe 5 are connected to the top of the cover body 2, a first barometer 4 is fixedly connected to one side of the first pipe 3, and a second barometer 6 is fixedly connected to one side of the second pipe 5, for detecting the air pressures of the first pipe 3 and the second pipe 5, respectively. The first pipe 3 and the second pipe 5 pass through the bottom of the sealing layer 12, and the first pipe 3 is arranged above the feed port 9. The first pipe 3 and the second pipe 5 are respectively connected to vacuum pumps (not shown in the figure), which can move external air to the inside of the box body 1.

[0027] Two groups of lighting lamps 11 are fixed on both sides of the bottom of the sealing layer 12 . A camera 13 is provided on one side of the lighting lamp 11 . The camera 13 is fixedly connected to the sealing layer 12 .

[0028] The sealing detection system includes a detection module and an analysis module. The detection module includes an air intake sub-module 1, an air intake sub-module 2, a shooting sub-module and a lighting sub-module. The air intake sub-module 1 and the air intake sub-module 2 are electrically connected to the air pump, the shooting sub-module is electrically connected to the camera 13, and the lighting sub-module is electrically connected to the lighting lamp 11.

[0029] The analysis module includes an air pressure receiving submodule, an image recognition submodule and a time recording submodule. The air pressure receiving submodule is electrically connected to the first barometer 4 and the second barometer 6. The image recognition submodule is electrically connected to the shooting submodule. The time recording submodule is used to record time.

[0030] The operation of the seal detection system includes the following steps:

[0031] Step 1: Place the storage cylinder 8 on the bottom plate, and start the linear start to move the storage cylinder 8 into the box body 1;

[0032] Step 2: Cover the cover body 2 onto the box body 1 so that the feed port 9 is connected to the first pipe 3, start the air intake submodule 1 to control the air pump to start, and pump the gas into the feed port 9 through the first pipe 3 and then into the storage tube 8;

[0033] It should be noted that the connection between the feed port 9 and the first pipeline 3 is a sealed connection to prevent gas leakage.

[0034] Step 3: The first barometer 4 detects the air pressure on the first pipeline 3 and transmits the signal to the air pressure receiving submodule to determine whether there is a gap inside the storage tube 8;

[0035] Specifically, the staff sets a constant air pressure in the storage cylinder 8 in the air pressure receiving submodule. When the air pressure value detected in real time by the first barometer 4 on the first pipeline 3 reaches the set constant air pressure value, the air intake submodule 1 is paused to stop the air intake into the storage cylinder 8. At this time, the first barometer 4 transmits the pressure value of stopping the air intake to the pressure receiving submodule in real time, and compares it with the constant air pressure. If the pressure value detected by the first barometer 4 does not change when the air intake is paused, it means that the sealing of the storage cylinder 8 is good. If the pressure value detected by the first barometer 4 decreases below the constant pressure value over time when the air intake is paused, it means that there is a gap in the storage cylinder 8 and the sealing is poor.

[0036] Step 4: When there is a gap in the storage cylinder 8, a signal is transmitted to the voice alarm device to notify the staff to remove the storage cylinder 8 with problems. When there is no gap inside the storage cylinder 8, the staff removes the cover 2 and pours trifluoroethyl acetate into the storage cylinder 8 through the feed port 9. When a certain amount of trifluoroethyl acetate is filled into the storage cylinder 8, the feed port is sealed, and the sealing performance of the feed port 9 is further determined.

[0037] Step 4 includes the following specific steps:

[0038] Step 4-a: After the trifluoroethyl acetate is loaded into the storage tube 8, the cover 2 is placed on the top of the box 1, and the lighting submodule is started to turn on the lighting lamp 11 to illuminate the interior of the box 1;

[0039] Step 4-b: Start the vacuum pump through the air intake submodule 2 to pump the gas into the interior of the box 1 through the second pipe 5. The second barometer 6 detects the air pressure on the second pipe 5 in real time to determine the sealing of the feed inlet 9;

[0040] Specifically, the staff also sets a constant air pressure in the box 1 in the air pressure receiving submodule. When the air pressure value detected in real time by the second barometer 6 on the second pipe 5 reaches the set constant air pressure, the air intake is suspended. At this time, the pressure value detected in real time by the second barometer 6 is transmitted to the air pressure receiving submodule and compared with the set constant air pressure. If the real-time detected air pressure is equal to the constant air pressure, it indicates that the feeding port 9 of the storage cylinder 8 is well sealed. If the real-time detected air pressure is lower than the constant air pressure, it indicates that the feeding port 9 of the storage cylinder 8 is not well sealed. At this time, the signal is transmitted to the voice alarm device to remind the staff to strengthen the seal.

[0041] Step 4-c: When it is determined that there is no problem with the sealing of the feed port 9, the air pressure in the box body 1 is further increased, and the camera 13 is used to photograph whether the storage tube 8 is deformed in the high air pressure, so as to judge the quality of the storage tube 8.

[0042] Step 4-c includes the following specific steps:

[0043] Step 4-c1: When it is determined that the sealing of the feed inlet 9 is OK, a signal is transmitted to the air intake submodule 2 to continue to intake air into the box 1, thereby increasing the air pressure in the box 1;

[0044] Step 4-c2: When the air pressure in the box 1 increases, the outer wall of the storage tube 8 will be squeezed to cause deformation. At this time, the shooting submodule controls the camera 13 to start, take a picture of the outer wall of the storage tube 8, and analyze its deformation degree;

[0045] Specifically, the camera 13 takes a photo of the outer wall of the storage tube 8 and transmits it to the image recognition submodule to determine the degree of deformation. Since the staff sets a photo of the outer wall of the storage tube 8 with normal deformation in the image recognition submodule, the two are compared. If the deformation degree of the current photo is less than or equal to the normal deformation photo, it means that the deformation degree of the outer wall of the storage tube 8 is low. If the deformation degree of the current photo is greater than the normal deformation photo, it means that the deformation degree of the outer wall of the storage tube 8 is high.

[0046] Furthermore, when the air pressure in the box body 1 increases and causes the outer wall of the storage cylinder 8 to deform, the air pressure in the first pipe 3 is further detected by the first barometer 4. If the first barometer 4 detects the air pressure, it means that the storage cylinder 8 is squeezed by the gas in the box body 1, and the gas inside the storage cylinder 8 is squeezed from the feed port 9 into the first pipe 3, indicating that the seal of the feed port 9 cannot withstand the pressure. At this time, the signal is transmitted to the voice alarm device to alarm. Through this step, the sealing of the feed port can be further detected when judging the deformation degree of the storage cylinder 8, thereby improving the sealing quality and ensuring the safety of storing trifluoroethyl acetate.

[0047] Step 4-c3: When the outer wall of the storage cylinder 8 is deformed, the air intake submodule 2 is suspended, and then the second pipe 5 is opened to discharge the gas in the box 1. When there is no air pressure in the box 1, the outer wall of the storage cylinder 8 returns to its original state. The time it takes for the outer wall of the storage cylinder 8 to return to its original state is analyzed to determine the quality of the storage cylinder 8;

[0048] Specifically, when the box 1 starts to exhaust, the start time recording submodule starts timing, and the specified time is set to t. After reaching time t, the camera 13 takes a photo of the outer wall of the storage cylinder 8 to identify whether the outer wall of the storage cylinder 8 has returned to its original state. Within time t, if the outer wall of the storage cylinder 8 with a high degree of deformation returns to its original state, it means that the quality of the storage cylinder 8 is high. If the outer wall of the storage cylinder 8 with a high degree of deformation does not return to its original state, it means that the quality of the storage cylinder 8 is low. The signal is transmitted to the controller 7 to mark the storage cylinder 8, and the storage cylinders 8 with low quality are uniformly managed.
