Test tube and TATB solubility test device

Abstract

The present invention discloses a test tube and a solubility detection device for TATB, wherein the test tube comprises a tube body, wherein the tube body comprises an integrally formed straight tube section at the upper part and a contraction section at the lower part, wherein the inner diameter of the contraction section is smaller than the inner diameter of the straight tube section; wherein: the contraction section is used to increase the ratio of the crystal accommodation height to the accommodation volume. The test tube provided by the present invention only requires a small amount of crystals to be precipitated in order to shield the light, whereas in the prior art, a large amount of crystals needs to be precipitated in order to shield the light. Therefore, the detection device provided by the present invention greatly improves the sensitivity of detecting the crystals just precipitated because the contraction section is arranged at the lower part of the test tube.

Description

Technical Field

[0001] The invention relates to a test tube for containing TATB and a solubility detection device for detecting TATB. Background Art

[0002] Because 1,3,5-triamino-2,4-trinitrobenzene (TATB) is extremely insensitive to external effects such as light, heat, shock waves and mechanical impact, it is called "wooden" explosives. As an excellent high-energy passivation ammunition, TATB is highly favored in the military field. It is not only the best choice for the main charge of nuclear weapons, but also widely used in civilian fields such as deep well oil blasting and liquid crystal materials. The TATB molecule is a planar configuration, and its crystal structure is layered and similar to graphite. Although the interaction between TATB layers is weak, there are very strong hydrogen bonds between molecules in the layer because there are three amino groups and three nitro groups in its molecules. Therefore, TATB molecules are firmly combined together. This super strong hydrogen bond between molecules is much greater than the van der Waals force between TATB and solvent molecules, so TATB has a low solubility in almost all organic good solvents.

[0003] In the prior art, the solubility of TATB in a solvent is usually measured using the following well-known method:

[0004] TATB and a solvent are injected into a test tube in the prior art and mixed by oscillation. The mixed solution is then heated to completely dissolve the TATB. The solution is then gradually cooled, and a light emitter is used to emit light in cooperation with a photosensitive plate to detect whether crystals are precipitated at the bottom of the test tube. When the sensor just detects the appearance of crystals at the bottom of the test tube, the temperature of the solution is recorded. Then, based on the mass ratio of TATB and the solvent when mixed, the solubility of TATB at that temperature can be obtained (or, a corresponding relationship between solubility and temperature is established).

[0005] In the prior art, the light emitter emits light and cooperates with the photosensitive plate in the following manner: the light emitter is arranged on one side of the bottom of the test tube in the prior art, and the photosensitive plate is arranged on the other side of the test tube and opposite to the light emitter. The light emitter emits light horizontally to the bottom of the test tube. If the photosensitive plate senses the light, it is determined that no crystals have precipitated in the test tube. If the photosensitive plate does not sense the light, it means that the light is blocked by the crystals, which means that crystals have precipitated in the test tube.

[0006] However, the apparatus used in the above method has the following defects in detecting the solubility of TATB:

[0007] 1. To prevent the light from being unable to pass through the test tube because it is below the bottom of the test tube, the position where the light passes needs to be higher than the bottom of the test tube (strict and complex positioning structures and operations are required to make the light pass through the bottom of the test tube). However, this results in the need to wait until the crystals accumulate to the height through which the light passes before the light can be shielded. At this time, the amount of TATB crystals precipitated is relatively large, and the TATB solution is not in a state where crystals are just precipitated. Therefore, the sensitivity of the cooperation between the light emitter emitting light and the photosensitive plate to detect the crystals just precipitating is not high. Furthermore, since the solubility of TATB itself is already very low, when the state where the amount of TATB crystals precipitated is relatively large is mistakenly regarded as the state where crystals have just precipitated, this will inevitably lead to a very low accuracy of the detected solubility.

[0008] 2. Most of the related instruments do not have the function of oscillating the test tubes. Most of them rely on manual oscillation, and a few instruments only have the function of simple shaking on a horizontal plane.

[0009] 3. The driving mechanism can drive the test tube to move in any direction in space, thereby improving the oscillation effect of the test tube. Summary of the invention

[0013] The contraction section is used to increase the ratio of the crystal accommodation height to the accommodation volume.

[0014] Preferably, the inner diameter of the contraction section gradually decreases from top to bottom.

[0016] Preferably, a sealing ring is provided between the side wall of the cover body and the straight tube section.

[0017] The present invention also discloses a TATB solubility detection device, comprising:

[0018] A test tube, comprising a tube body, wherein the tube body comprises an integrally formed straight tube section at the upper part, a contraction section at the lower part, and a cover body arranged on the straight tube section, wherein the inner diameter of the contraction section is smaller than the inner diameter of the straight tube section, and the contraction section is used to increase the ratio of the crystal accommodation height to the accommodation volume;

[0022] a photosensitive plate disposed on the other side of the contraction section for receiving light;

[0023] The driving mechanism is arranged below the frame to drive the frame to move and drive the test tube to oscillate.

[0024] Preferably, the driving mechanism comprises:

[0025] A swing frame is rotatably arranged, and a core rod is formed in the middle of the swing frame;

[0026] An oscillating body, which is sleeved on the core rod and can rotate around the core rod, the rotation axis of the oscillating body is perpendicular to the rotation axis of the swing frame, and the lower part of the oscillating body has a pin, the axis of the pin is inclined and perpendicular to the axis of the rotating shaft of the oscillating body;

[0027] A motor, which is located below the oscillating body and is arranged vertically upward, wherein the axis of the output shaft of the motor is arranged at an angle to the axis of the pin shaft;

[0028] A connecting rod, comprising a rod body, and a shaft body and a sleeve body formed at both ends of the rod body, wherein the shaft body is arranged at an angle with the rod body, the axis of the sleeve body is perpendicular to the rod body, the shaft body is used to be coaxially arranged with the output shaft of the motor, and the sleeve body is sleeved on the pin shaft of the oscillating body and can rotate relative to the pin shaft;

[0029] The bottom of the frame is fixed on the oscillating body.

[0030] Preferably,

[0031] The upper part of the oscillating body forms a platform, and the bottom plate is fixed on the platform of the oscillating body;

[0032] The swing frame is a rectangular frame;

[0033] There are at least two support assemblies below the swing frame, respectively used to support the connecting beams located on both sides of the rotation axis of the swing frame; wherein:

[0034] The support assembly comprises:

[0035] Support rods;

[0036] A support plate, which is arranged at the upper end of the support rod to support the connecting beam;

[0037] A stopper, which is arranged at the lower end of the support rod;

[0038] A limit plate, the lower end of the support rod is provided with the limit plate, and the stop platform is located below the limit plate;

[0039] A spring is sleeved on the support rod. The spring adapts to the swing of the swing frame by contracting. When the swing frame loses power and stops swinging, the spring makes the stop platform abut against the limit plate, so that the swing frame is restored to a horizontal state under the support of the support plate.

[0046] Compared with the prior art, the test tube and the TATB solubility detection device disclosed in the present invention have the following beneficial effects:

[0047] 1. By setting the lower part of the test tube into a contraction section, the ratio of the crystal accommodation height to the accommodation volume of the contraction section is much greater than the ratio of the crystal accommodation height to the accommodation volume of the lower part of the test tube in the prior art. This means that when the same volume of crystals are precipitated, the length (or height) of the contraction section occupied by the crystals is much greater than the length of the bottom of the test tube in the prior art. In other words, if the light is irradiated at the same height from the bottom of the test tube, the test tube provided by the present invention only needs to precipitate a small amount of crystals to block the light, while in the prior art, a large amount of crystals need to be precipitated to block the light. Therefore, the detection device provided by the present invention greatly improves the sensitivity of detecting the crystals that have just precipitated because the contraction section is set at the lower part of the test tube.

[0048] 2. By providing a positioning plate with perforations, the extension amount of the contraction section can be guaranteed, so that the light can illuminate the same position of the test tube each time.

[0049] 3. The driving mechanism can drive the test tube to move in any direction in space, thereby improving the oscillation effect of the test tube.

[0050] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention.

[0063] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0064] like Figures 1 to 6 As shown, the present invention discloses a TATB solubility detection device, which includes: a test tube 10, a temperature sensor 60, a frame 20, a driving mechanism 30, a locking mechanism 50, a heating wire 70, an insulation sleeve 71, a laser emitter 81, a photosensitive plate 82 and a support assembly 40.

[0065] like Figure 1 and Figure 2 As shown, the test tube 10 includes a tube body 11, a cover body 12 and a sealing ring 13. In the present invention, the tube body 11 includes an integrally formed straight tube section 111 and a contraction section 112, the straight tube section 111 is located above the contraction section 112, the inner diameter of the contraction section 112 is smaller than that of the straight tube section 111, and the inner diameter of the contraction section 112 gradually decreases from top to bottom, and the tube wall of the contraction section 112 is set to be tapered.

[0066] An external thread is formed on the upper barrel of the straight barrel section 111, and the cover body 12 is used to seal the port of the straight barrel section 111, and the side wall of the cover body 12 is used to screw with the external thread, and the sealing ring 13 is arranged between the straight barrel section 111 and the side wall of the cover body 12; a mounting hole is opened on the cover body 12, and the temperature sensor 60 extends from the mounting hole into the tube body 11.

[0067] The test tube 10 is used to contain TATA solution, and the temperature sensor 60 is used to detect the stability of the solution.

[0068] like Figure 3 As shown, the frame 20 includes a top plate 21 , a bottom plate 22 located below the top plate 21 , and a vertical plate 23 for connecting the top plate 21 and the bottom plate 22 , and the vertical plate 23 is located on the same side of the bottom plate 22 and the top plate 21 .

[0069] A through hole is formed on the top plate 21 , and the lower end of the test tube 10 passes through the through hole and extends between the top plate 21 and the bottom plate 22 .

[0070] The locking mechanism 50 includes a locking sleeve 51 and a locking nut 52. The lower end of the locking sleeve 51 is formed with a flange, which is used to be fixed on the top plate 21, and the locking sleeve 51 is opposite to the through hole. The upper part of the locking sleeve 51 is formed with a plurality of clamping petals, which surround a cone sleeve 511, and the locking nut 52 is sleeved on the cone sleeve 511. After the test tube 10 passes through the through hole, the clamping petals are tightened by tightening the locking nut 52 so that the test tube 10 is fixed to the frame 20.

[0071] like Figure 3 and Figure 4 As shown, a horizontal positioning plate 24 is arranged between the top plate 21 and the bottom plate 22 and near the bottom plate 22. A through hole 241 is provided on the positioning plate 24. The through hole 241 is a tapered hole with the same taper as the outer wall of the contraction section 112 of the test tube 10. After the contraction section 112 of the test tube 10 passes through the tapered hole, it is restricted by the tapered hole to position the height of the test tube 10. In this way, the length of the contraction section 112 extending out of the positioning plate 24 is determined and unchanged. Preferably, a rubber sleeve 242 is arranged in the tapered hole to prevent the contraction section 112 from being damaged when passing through.

[0072] like Figure 3 and Figure 4 As shown, a bracket 811 is set up on one side of the lower part of the contraction section 112, and the laser emitter 81 is horizontally installed on the bracket 811. A photosensitive plate 82 is fixed on the other side at the same height as the laser emitter 81, and the photosensitive plate 82 is used to sense the light emitted by the laser emitter 81.

[0073] The heating wire 70 is arranged around the outside of the tube body 11, and the heating wire 70 is used to heat the test tube 10, and the temperature sensor 60 is used to detect the heated temperature.

[0074] An insulating sleeve 71 is provided outside the heating wire 70 . The upper end of the insulating sleeve 71 is fixed to the bottom of the top plate 21 of the frame 20 by means of a flange. The insulating sleeve 71 is used to store heat and ensure that the test tube 10 is heated evenly.

[0075] The driving mechanism 30 is located below the frame 20 , and is used to drive the frame 20 to move, thereby causing the test tube 10 fixed on the frame 20 to oscillate.

[0076] like Figure 3 As shown, specifically, the driving mechanism 30 includes: a swing frame 32 , an oscillating body 31 , a motor 33 and a connecting rod 34 .

[0077] The swing frame 32 is roughly in the shape of a rectangular frame, and has a first connecting beam and a second connecting beam 322 arranged opposite to each other. The middle part of the first connecting beam has a rotating shaft 321, and the rotating shaft 321 enables the swing frame 32 to rotate on a vertical plane. A core rod 311 is arranged between the two second connecting beams 322.

[0078] The oscillating body 31 is sleeved on the core rod 311 and can rotate around the core rod 311 , so that the rotation axis of the oscillating body 31 is perpendicular to the rotation axis of the swing frame 32 .

[0079] A pin shaft 312 is formed on one side of the bottom of the oscillating body 31 , and the axis of the pin shaft 312 is inclined and arranged at an angle with the rotating shaft 321 of the swing frame 32 .

[0080] The motor 33 is vertically arranged and located below the oscillating body 31 , and the axis of the output shaft 331 of the motor 33 intersects and is perpendicular to the axes of the swing frame 32 and the oscillating body 31 .

[0081] The connecting rod 34 is used to connect the motor 33 and the pin shaft 312. Specifically, the connecting rod 34 includes a rod body and a sleeve 342 and a shaft body 341 located at both ends of the rod body. The shaft body 341 is set at an angle with the rod body, and the sleeve 342 is perpendicular to the rod body. The shaft body 341 is connected to the output shaft 331 of the motor 33, and is coaxially set with the output shaft 331 and rotates coaxially with the output shaft 331. The pin shaft 312 of the oscillating body 31 extends into the sleeve 342 and can rotate relative to the sleeve 342.

[0082] The base plate 22 of the frame 20 is fixed on the oscillating body 31, so that the motor 33 drives the connecting rod 34 to rotate, so that the connecting rod 34 drives the oscillating body 31 to move. Due to the swing and the above-mentioned setting of the oscillating body 31, the oscillating body 31 will make at least two degrees of freedom of spatial movement under the drive of the connecting rod 34, thereby driving the frame 20 and the test tube 10 to oscillate in a spatial motion manner.

[0083] The upper part of the oscillating body 31 forms a platform 313 , and the bottom plate 22 is fixed on the vibration platform 313 .

[0084] The supporting components 40 include four supporting components 40 , which are disposed in pairs below the second connecting beams 322 on both sides of the rotating shaft 321 to support the second connecting beams 322 .

[0085] like Figure 5As shown, specifically, each support assembly 40 includes: a support rod 41, a support plate 42, a stopper 43, a limit plate 44 and a spring 45. The support plate 42 has a U-shaped groove with a notch facing upwards. The support plate 42 is fixed to the upper end of the support rod 41 to support the second connecting beam 322. The limit plate 44 is fixedly arranged. The lower end of the support rod 41 is penetrated by the limit plate 44. The stopper 43 is arranged at the lower end of the support rod 41. The spring 45 is sleeved on the support rod 41 and is in a compressed state. When the stopper 43 stops at the limit plate 44, all the support plates 42 of the four support assemblies 40 are located on the same horizontal plane.

[0086] When the driving mechanism 30 drives the frame 20 to move in space, the spring 45 expands and contracts with the swing of the swing frame 32 to adapt to the swinging action. When the motor 33 stops running and the driving mechanism 30 stops driving the frame 20, the spring 45 makes the stopper 43 abut against the bottom of the limit plate 44. At this time, the four support plates 42 are in the same plane, which makes the swing frame 32 return to a horizontal state.

[0087] It should be noted that the transmission from the motor 33 to the oscillating body 31 is unique. If any one of the components therebetween is restricted, the other components will not move. Therefore, when the motor 33 stops running, the four support plates 42 restrict the swing frame 32, and the operation of the oscillating body 31 is also restricted. In this way, by configuring the platform 313 of the oscillating body 31 to be in a horizontal state when the swing frame 32 is in a horizontal state, the platform 313 of the oscillating body 31 can automatically return to a horizontal state under the action of the supporting assembly 40 after the motor 33 stops running.

[0088] The working process of the above detection device is introduced below:

[0089] First, the solvent and TATB solute are heated in the test tube 10, and then the test tube 10 is passed through the through hole of the top plate 21 on the frame 20, and the contraction section 112 of the test tube 10 passes through the through hole 241 of the positioning plate 24. The through hole 241 defines the amount by which the contraction section 112 extends out of the positioning plate 24, that is, defines the height of the bottom of the test tube 10. At this time, the laser emitter 81 is opposite to the upper part of the bottom of the contraction section 112, so that the laser emitter 81 can irradiate the lower part of the contraction section 112.

[0090] Then, the temperature sensor 60 is passed through the cover 12 of the test tube 10 and extended into the solvent (or solution) to measure the temperature of the solvent.

[0091] The heating wire 70 is energized to heat the test tube 10, and the motor 33 is started at the same time, so that the driving mechanism 30 drives the test tube 10 to oscillate to accelerate the dissolution of the TATB solute. After each oscillation and heating for a period of time and standing to allow the crystal 100 to slide into the bottom of the test tube 10, the laser emitter 81 and the photosensitive plate 82 are used to detect whether the TATB is completely dissolved. For example, if the photosensitive plate 82 receives the light emitted by the laser emitter 81, it means that the TATB has been completely dissolved. Otherwise, it means that the TATB is not completely dissolved.

[0092] When TATB is completely dissolved, the current supplied to the heating wire 70 is reduced to slowly reduce the temperature of the solvent in the test tube 10, and the signal of the received light of the photosensitive plate 82 is detected in real time to prove whether the light is blocked by the crystal 100 sliding into the bottom of the test tube 10. When the light is blocked, the temperature detected by the temperature sensor 60 is recorded immediately.

[0093] Based on the detected temperature, the solubility of TATB corresponding to the temperature is obtained.

[0094] The advantages of the detection device provided by the present invention are:

[0095] 1. By setting the lower part of the test tube 10 as a contraction section 112, the ratio of the accommodation height of the contraction section 112 to the accommodation volume of the crystal 100 is much greater than the ratio of the accommodation height of the lower part of the test tube 10 in the prior art to the accommodation volume of the crystal 100. This means that when the same volume of crystal 100 is precipitated, the length (or height) of the contraction section 112 occupied by the crystal 100 is much greater than the length of the bottom of the test tube 10 in the prior art. In other words, if the light is irradiated at the same height from the bottom of the test tube 10, the test tube 10 provided by the present invention only needs to precipitate a small amount of crystal 100 to shield the light, while in the prior art, the crystal 100 needs to precipitate a large amount to shield the light. Therefore, the detection device provided by the present invention greatly improves the sensitivity of detecting the crystal 100 just precipitated because the contraction section 112 is set at the lower part of the test tube 10.

[0096] 2. By providing a positioning plate 24 with a through hole 241 , the extension amount of the contraction section 112 can be guaranteed, so that the light irradiates the same position of the test tube 10 each time.

[0097] 3. The driving mechanism 30 can drive the test tube 10 to move in any direction in space, thereby improving the oscillation effect of the test tube 10.
