Description

Technical Field

[0001] The invention relates to the technical field of ampoule bottle sealing devices, in particular to a grouting and ventilation mechanism and a grouting and ventilation method thereof, and an ampoule bottle filling and sealing device. Background Art

[0002] Existing ampoule sealing devices primarily consist of a grouting station and a sealing station. The grouting station is used to deliver slurry into the ampoule, while the sealing station is used to sinter and seal the ampoule. However, existing ampoule sealing devices suffer from the following major issues: First, the sample holder on the sealing station cannot rotate or move up and down, and the sealing flame has a single angle. These devices are generally only suitable for sealing small, thin-walled ampoules, which typically range in size from 1 to 20 ml and are 0.6 to 13 cm tall, with very thin walls of only 0.2 to 0.3 mm. Second, sealing is typically ignited with liquefied gas, which is highly dangerous. Third, the liquid injection device uses a pumping principle, and the liquid suction speed is too fast. Existing sealing machines with liquid injection functions are only suitable for water-based liquids or light oils such as gasoline, kerosene, and other extremely viscous liquids. They cannot inject lubricants with higher viscosities, such as organic heat transfer fluids. Fourth, even existing equipment cannot achieve the air replacement process in the ampoule during the sample preparation process for the organic heat transfer thermal stability test. The air in the ampoule needs to be replaced manually through an inert gas pipe. Fifth, there is no ampoule opening function. When conducting experiments on the thermal stability of organic heat transfer fluids, the ampoule needs to be opened manually, which is slow, poor in quality, and unsafe.

[0003] To this end, the patent number "202010042155.7" and the patent name "An integrated device for washing, moistening and sealing an ampoule" discloses an ampoule sealing device, including a main body casing, a fixed disk, a turntable, a flame nozzle and a filling mechanism; the fixed disk is fixed to the main body casing by a pillar, and the turntable is located above the fixed disk and is driven to rotate by a rotating motor. A mechanism is provided under the turntable to drive the ampoule bottle in the turntable hole to rotate, thereby solving the problems of a single sealing flame angle and the use of liquefied gas for ignition, which is very dangerous. The flame nozzle is driven up and down by a lifting mechanism, and the flame nozzle uses an oxyhydrogen flame to melt the bottle mouth. The filling mechanism includes an inflation pipeline and a filling pipeline. The inflation pipeline fills the ampoule bottle with inert gas for protection, and the filling pipeline uses a pumping principle for grouting, thereby solving the problem of inability to replace the cavity. Although the above patent solves problems one, two and four, problems three and five are not solved because the pumping principle is still adopted and no bottle opening mechanism is provided. Summary of the Invention

[0020] 1. In the grouting and ventilation mechanism of the present invention, by controlling the lifting and lowering of the liquid injection syringe, it is possible to realize whether the slurry feeding pipe is below or above the liquid level in the liquid storage tank. When the slurry feeding pipe is below the liquid level, under the pressure of the inert gas transported by the gas injection pipe, the slurry will be fed into the grouting pipe through the slurry feeding pipe, and then fed into the ampoule bottle through the tank slurry pipe. This pressure-feeding method can not only pressure-feed liquids with lower viscosity, such as gasoline, kerosene, etc., but also pressure-feed liquids with higher viscosity, such as lubricating oil, especially organic heat carrier (thermal oil, a kind of lubricating oil). When the slurry feeding pipe is above the liquid level, under the pressure of the inert gas transported by the gas injection pipe, what enters the slurry feeding pipe is no longer slurry, but inert gas. After the inert gas is injected into the ampoule bottle through the grouting pipe, the gas in the ampoule bottle can be replaced. At the same time, the inert gas can also play a role in cleaning the grouting pipe and the slurry feeding pipe. The grouting and ventilation mechanism can be widely used in the ampoule bottle filling and sealing process.

[0021] 2. In the grouting ventilation method of the present invention, the above-mentioned grouting ventilation mechanism is adopted, and the slurry can be transported and the gas replacement can be completed simply by switching the height of the injection syringe.

[0022] 3. The ampoule filling and sealing device of the grouting and ventilation mechanism of the present invention provides two setting ideas. The first one has only a sealing station and a filling station, which can realize the sealing, filling and ventilation of the ampoule. The other one is equipped with a cutting station, which can cut the sealed ampoule. In subsequent tests, there is no need to manually open the bottle. The cutting station automatically opens the bottle, which can improve the efficiency and safety of opening the bottle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with 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 making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] This embodiment provides a grouting ventilation mechanism, such as Figures 1 to 8 As shown, it includes a liquid injection syringe 101 and a grouting pipe 201. The end of the liquid injection syringe 101 away from the needle tip is plugged with a sealing plug 104. The sealing plug 104 is provided with two tube holes, one of which is plugged with a slurry feeding pipe 102 through interference fit, and the other is plugged with an air injection pipe 103. The air injection pipe 103 is used to connect to an inert gas supply system. The inert gas supply system can provide inert gas, such as N2, and the slurry feeding pipe 102 is connected to the grouting pipe 201. Preferably, the air injection pipe 103 is connected to the inert gas supply system through a nitrogen hose 111, and the slurry feeding pipe 102 is connected to the grouting pipe 201 through a liquid injection hose 110. The air injection pipe 103 is shorter than the slurry feeding pipe 102. Preferably, the length of the slurry feeding pipe 102 is slightly smaller than that of the liquid injection syringe 101, and is roughly located above the needle tip for reference. Figure 7 and Figure 8As shown. The injection syringe 101 and the grouting pipe 201 can both be raised and lowered. The grouting pipe 201 can be inserted into and out of the ampoule bottle 5 when it descends and rises, and the injection syringe 101 can be inserted into the bottle cap of the liquid storage bottle 4 below it and extend below the liquid level of the liquid storage bottle 4. At this time, the slurry delivery pipe 102 also extends below the liquid storage bottle along with the injection syringe 101, and the gas injection pipe 103 is located above the liquid level in the liquid storage bottle 4. In this way, after the inert gas of the inert gas supply system is introduced into the liquid storage bottle 4 through the gas injection pipe 103, as the gas is gradually injected, the pressure in the liquid storage bottle 4 gradually increases, and the inert gas will press the liquid in the liquid storage bottle 4 into the grouting pipe 201 through the slurry delivery pipe 102, and then into the ampoule bottle 5, realizing a pressurized liquid delivery method. This delivery method can not only deliver liquids with lower viscosity, but also deliver slurries with higher viscosity, such as lubricating oils with higher viscosity, organic heat carrier products, etc. After the delivery is completed, the injection syringe 101 is lifted up to separate the slurry delivery tube 102 from the liquid level in the liquid storage bottle 4 and to be above the liquid level. At this time, when the inert gas is injected, what enters the slurry delivery tube 102 is no longer liquid, but inert gas, thereby replacing the air in the ampoule bottle 5, completing the air replacement process. At the same time, the inert gas can also play a role in cleaning the slurry delivery tube 102. Preferably, a liquid level sensor can be provided at a specified height outside the grouting tube 201. When the liquid level in the ampoule bottle 5 is submerged above the liquid level sensor outside the grouting tube 201, it can be known whether the liquid level in the ampoule bottle 5 has reached the preset height.

[0040] Example 2

[0041] This embodiment provides a grouting ventilation method, which adopts the grouting ventilation mechanism in embodiment 1. Figures 1 to 8 As shown, the following steps are included:

[0042] S1. Lower the liquid injection syringe 101 and the grouting tube 201 respectively. Insert the liquid injection syringe 101 into the bottle cap of the liquid storage bottle 4 directly below it, and make the slurry delivery tube 102 below the liquid level in the liquid storage bottle 4, and the gas injection tube 103 above the liquid level in the liquid storage bottle 4. Insert the grouting tube 201 into the ampoule bottle 5 below it through the bottle mouth of the ampoule bottle 5;

[0043] S2, open the inert gas supply system, the liquid in the liquid storage bottle 4 is sent to the grouting pipe 201 by the grouting pipe 102 as the pressure increases, and then sent into the ampoule bottle 5 by the grouting pipe 201 until the filling is in place, and the gas supply of the inert gas supply system is suspended;

[0044] S3, lift the injection syringe 101, so that the slurry delivery pipe 102 rises and separates from the liquid level in the liquid storage bottle 4, so that it is also located above the liquid level in the liquid storage bottle 4, restart the inert gas supply system, and the inert gas is delivered into the ampoule bottle 5 through the slurry delivery pipe 102 and the grouting pipe 201 to achieve gas replacement;

[0045] S4, after replacement is completed, lift the grouting pipe 201 to separate it from the ampoule bottle 5, and then the ampoule bottle 5 can be sent to the fusion sealing, which should be done in time to avoid the escape of inert gas. The fusion sealing can be done manually or by a fusion sealing machine, which is not limited here.

[0046] Example 3

[0047] This embodiment provides an ampoule filling and sealing device, which adopts the grouting and ventilation mechanism as in embodiment 1. Figures 1 to 8 As shown, it includes a grouting station 1 and a sealing station 2. The grouting station 1 is provided with a positioning groove 106, which is located directly below the liquid injection syringe 101 for placing the liquid storage bottle 4. The sealing station 2 is provided with a filling station, a sealing station, and a transfer mechanism. The filling station is located below the grouting pipe 201. The sealing station is used to seal the ampoule bottle 5. The transfer mechanism can transfer the ampoule bottle 5 between the filling station and the sealing station.

[0048] Working principle: first, place the liquid storage bottle 4 into the positioning groove 106, place the ampoule bottle 5 on the transfer mechanism, and then send the ampoule bottle 5 to the filling station through the transfer mechanism, then the liquid injection syringe 101 and the grouting tube 201 can be driven down, and respectively extend into the liquid storage bottle 4 and the ampoule bottle 5 for filling and ventilation. After the ventilation is completed, the ampoule bottle 5 is sent to the sealing station through the transfer mechanism, and then it can be sealed to complete the filling and sealing of the ampoule bottle 5.

[0049] Furthermore, in this embodiment, Figures 1 to 8 As shown, the grouting table 1 is provided with a first lifting mechanism, which includes a vertically arranged first linear guide rail 107. The first linear guide rail 107 is provided with a first slider 108. The first slider 108 is fixedly connected to the injection syringe 101. The first slider 108 slides up and down along the first linear guide rail 107 under the drive of the driving system, so as to realize the lifting and lowering of the injection syringe 101.

[0050] In order to position the liquid storage bottle 4 and prevent the liquid storage bottle 4 from shaking when the injection syringe 101 is inserted into the bottle cap of the liquid storage bottle 4, Figures 1 to 8 As shown, in this embodiment, a second slider 109 is further provided on the first linear guide rail 107 and is located below the first slider 108. A positioning sleeve 105 is fixed on the second slider 109. The inner diameter of the positioning sleeve 105 matches the outer diameter of the bottle cap of the liquid storage bottle 4. When the second slider 109 is driven down by the driving system, the end of the positioning sleeve 105 can be sleeved on the outside of the bottle cap of the liquid storage bottle 4, thereby limiting it to ensure that the liquid storage bottle 4 will not shake when the injection syringe 101 penetrates the bottle cap.

[0051] Furthermore, in this embodiment, Figures 1 to 8As shown, a second lifting mechanism is provided on the sealing platform 2, and the second lifting mechanism includes a second linear guide rail 213 arranged vertically. A third slider 214 is provided on the second linear guide rail 213, and the third slider 214 is fixedly connected to the grouting pipe 201. The third slider 214 is driven by the driving system and can move up and down along the second linear guide rail 213, thereby realizing the lifting and lowering of the grouting pipe 201.

[0052] In this embodiment, Figures 1 to 8 As shown, the transfer mechanism includes a first rotating frame 202 and a first rotating assembly. The first rotating frame 202 includes a first rotating shaft 203 that is rotatably connected to the sealing platform 2. The first rotating shaft 203 is vertically rotatably connected to the sealing platform 2 via a bearing. A first upper turntable 204, a first middle turntable 205, and a first lower turntable 206 are fixed to the first rotating shaft 203 from top to bottom. The first upper turntable 204, the first middle turntable 205, and the first lower turntable 206 are coaxially arranged with the first rotating shaft 203. The first upper turntable 204 and the first middle turntable 205 are respectively provided with ampoule positioning holes 207. Multiple ampoule positioning holes 207 can be provided and arranged circumferentially along the first upper turntable 204 and the first middle turntable 205. This allows multiple ampoules 5 to be placed on the transfer mechanism simultaneously, thereby improving filling and sealing efficiency. The first lower turntable 206 is provided with a first positioning claw 208 corresponding to each ampoule positioning hole 207 for positioning the ampoule 5. The rotating assembly includes a first rotating motor 209, a first drive wheel 210, and a first driven wheel 211. The first rotating motor 209 is fixed to the sealing station 2. The first drive wheel 210 is fixed to the output shaft of the first rotating motor 209. The first driven wheel 211 is coaxially fixed to the first rotating shaft 203. The first driving wheel 210 and the first driven wheel 211 are connected by a first driving belt 212. When the first rotating motor 209 is turned on, the first driving belt 212, driven by the first driving wheel 210, can drive the first driven wheel 211 to rotate synchronously, thereby driving the first rotating shaft 203 to rotate, driving the first upper turntable 204, the first middle turntable 205, and the first lower turntable 206 to rotate, thereby enabling the switching of ampoules between the filling station and the sealing station. Preferably, the diameter of the first driven wheel 211 is greater than the diameter of the first driving wheel 210 .

[0053] Furthermore, in this embodiment, Figures 1 to 8As shown, the sealing station includes a spray gun mechanism, a third lifting mechanism and a sealing mechanism. The spray gun mechanism includes a flame nozzle 215 and a first drive motor 216. The first drive motor 216 is fixed on the first lower turntable 206. The first positioning claw 208 is fixed on the output shaft of the first drive motor 216 to drive the first drive motor 216 to rotate, thereby driving the ampoule bottle 5 to rotate, so that the flame sprayed by the flame nozzle 215 can heat the bottle mouth of the ampoule bottle 5 360 degrees, solving the problem of a single heating direction. The flame nozzle 215 is connected to a hydrogen compressor and uses hydrogen as fuel gas. Compared with liquefied gas, safety can be greatly improved. The third lifting mechanism includes a third linear guide rail 217 vertically arranged on the sealing platform 2. The third linear guide rail 217 is provided with a fourth slider 218, and the fourth slider 218 is fixedly connected to the flame nozzle 215. Driven by the drive system, the fourth slider 218 can move the flame nozzle 215 up and down, thereby adjusting the spray position of the flame nozzle 215, heating the mouth of the ampoule 5 up and down, and improving heating uniformity. The sealing mechanism includes a metal mechanical gripper 219, which can pinch the mouth of the high-temperature heated ampoule 5 and pull it upward to achieve sealing. The metal mechanical gripper 219 can be an existing fully automatic robot. Since it is existing technology, it will not be described in detail here.

[0054] In this embodiment, Figures 1 to 8 As shown, the ampoule filling and sealing device also includes a cutting table 3, which is equipped with a second rotating frame 301, a second rotating assembly, a cutting mechanism, a fourth lifting mechanism, and a storage groove 312. The second rotating frame 301 is used to place the cooled ampoules 5 after sealing. The second rotating assembly is used to drive the second rotating frame 301 to rotate, transferring the ampoule 5 above it to the cutting mechanism for cutting the bottle mouth. The storage groove 312 is used to hold the cut bottle mouth of the ampoule 5. The fourth lifting mechanism is used to drive the cutting mechanism up and down to achieve precise cutting.

[0055] Furthermore, in this embodiment, Figures 1 to 8As shown, the second rotating frame 301 includes a second rotating shaft 302, to which are coaxially fixed a second upper turntable 303, a second middle turntable 304, and a second lower turntable 305. The second upper turntable 303, the second middle turntable 304, and the second lower turntable 305 are arranged in order from top to bottom. The second upper turntable 303 and the second middle turntable 304 are each provided with corresponding ampoule placement holes 306. Multiple ampoule placement holes 306 can also be provided, arranged circumferentially along the turntable surface to improve cutting efficiency. The second lower turntable 305 is provided with a second positioning claw 307 corresponding to each ampoule placement hole 306.

The second drive wheel 309 is fixed to the output shaft of the second rotating motor 308. The second driven wheel 310 is coaxially fixed to the second rotating shaft 302. The second drive wheel 309 and the second driven wheel 310 are connected by a second drive belt 311. The fourth lifting mechanism includes a fourth linear guide 313 and a fifth slider 314 mounted on the fourth linear guide 313. The cutting mechanism includes a motorized grinding wheel 317, a rubber mechanical gripper 315, and a second driving motor 318. The motorized grinding wheel 317 is connected to the fifth slider 314 via a motorized telescopic rod 316. The second driving motor 318 is fixed to the second lower turntable 305. The second positioning claw 307 is fixed to the output shaft of the second driving motor 318 to drive the second positioning claw 307 to rotate. The rubber mechanical gripper 315 can pinch the mouth of the ampoule bottle 5 after sealing so as to position it during cutting. During cutting, the rubber mechanical gripper 315 first pinches the mouth of the ampoule bottle 5, and the electric telescopic rod 316 extends to drive the electric grinding wheel 317 to cut the mouth of the ampoule bottle 5. If it is difficult to cut it off in one go, the electric telescopic rod 316 retracts, and the rubber mechanical gripper 315 can first release the mouth of the ampoule bottle 5, and the second driving motor 318 drives the second positioning claw 307 to rotate, so that the ampoule bottle 5 can be cut again on the other side, thereby improving the cutting effect.

[0056] In this embodiment, Figures 1 to 8 As shown, the overall working process of the ampoule filling and sealing device after the cutting table 3 is added is as follows (taking the filling of organic heat carrier samples as an example):

[0057] First, manually load the ampoule 5 into the ampoule positioning hole 207 of the sealing station 2. The first positioning claw 208 clamps the bottom of the ampoule 5. Then, place the liquid storage bottle 4 containing the organic heat carrier into the positioning groove 106. The liquid storage bottle 4 is a 1L aluminum bottle.

[0058] Then, the first rotating frame 202 is rotated to rotate the ampoule bottle 5 to the position directly below the grouting tube 201. The second slider 109 and the third slider 214 are respectively activated. The second slider 109 drives the positioning sleeve 105 to descend so that it is sleeved on the outside of the bottle cap of the liquid storage bottle 4. The third slider 214 drives the grouting tube 201 to extend into the ampoule bottle 5. Subsequently, the first slider 108 is activated to drive the steel liquid injection syringe 101 to be inserted into the bottle cap of the liquid storage bottle 4. The slurry delivery tube 102 is located below the liquid level of the organic heat carrier, and the gas injection tube 103 is located above the liquid level of the organic heat carrier.

[0059] Then, the inert gas supply system is started, and N2 is filled into the liquid storage bottle 4 through the gas injection pipe 103 to replenish the pressure. When the pressure in the liquid storage bottle 4 is sufficient, the organic heat carrier is slowly pressed into the ampoule bottle 5 through the slurry delivery pipe 102. When the liquid level in the ampoule bottle 5 reaches the target position, the liquid injection syringe 101 is raised to 1 cm below the bottle mouth of the liquid storage bottle 4. At this time, the slurry delivery pipe 102 and the gas injection pipe 103 are both above the liquid level of the organic heat carrier. N2 is continued to be introduced for 1-2 minutes. At this time, the introduced N2 will be injected into the ampoule bottle 5 through the slurry delivery pipe 102, replacing the air in the ampoule bottle 5 while also cleaning the slurry delivery pipe 102 stained with the organic heat carrier;

[0060] Then, after the ventilation time is over, the grouting pipe 201 is lifted, and the ampoule bottle 5 rotates to the flame nozzle 215 along with the first rotating frame 202. The next ampoule bottle 5 is also rotated to the bottom of the grouting pipe 201 for the next liquid injection. At this time, the fourth slider 218 adjusts the height of the flame nozzle 215 so that it is aligned with the ampoule bottle 5 rotated here, and flame spraying is performed. The first drive motor 216 is started to drive the ampoule bottle 5 to rotate slowly. At the same time, the fourth slider 218 moves the flame nozzle 215 up and down to achieve rapid and uniform heating of the ampoule bottle 5. After heating for a certain period of time, the metal mechanical gripper 219 pinches and pulls the bottle mouth of the ampoule bottle 5 to achieve melting and sealing.

[0061] Finally, the sealed ampoule 5 containing the organic heat carrier is placed in the ampoule placement hole 306 of the cutting table 3 after being frozen and warmed. After the bottle mouth is fixed from above by a rubber mechanical gripper 315, it is cut 2 cm below the bottle mouth by an electric grinding wheel 317. The cut bottle mouth is placed into the storage groove 312 by the rubber mechanical gripper 315 for collection before proceeding to the next process. The next process mainly includes three experimental parts: weighing and calculating losses, determining the non-evaporable product, and chromatographic analysis. Since these are not the main steps of this device, they are not elaborated on here.

[0062] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
