[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives, with the characteristics of high viscosity, difficulty in dispersion, and easy agglomeration. For the test of the root inhibitor content of asphalt-based root-penetration-resistant waterproofing membrane, the working principle is to extract the root inhibitor from the solid asphalt sample (asphalt coating material) by solvent dissolution, water bath ultrasound, etc., and use saponification reaction to fully hydrolyze the root inhibitor content to obtain the active substance MCPP acid, and use high performance liquid chromatography to test, with retention time for qualitative analysis and external standard method for quantitative analysis. The sample pretreatment step requires the use of an analytical balance to accurately weigh the solid asphalt sample (asphalt coating material), then put it into a stoppered conical flask, add acetone, and place the conical flask in an ultrasonic water bath for ultrasound at room temperature to extract the root inhibitor.

[0003] However, the existing technology has the following problems through the ultrasonic process: 1. Due to the high viscosity of asphalt, the solid asphalt sample after being weighed is easy to clump and difficult to disperse; 2.

[0038] An embodiment of the present invention provides a solid asphalt quantitative uniform dispersion ultrasonic mold, which includes a support rod 2, a plurality of connecting frames 102 and a plurality of sample boxes 101.

[0039] A plurality of connecting frames 102 are connected to one end of the support rod 2 , and the plurality of connecting frames 102 are placed in a conical flask filled with acetone solution through the support rod 2 , while a gripping position is provided at the other end of the support rod 2 .

[0040] At least one sample box 101 is arranged on each connecting frame 102 , and the connecting frame 102 is used to fix the position of the sample box 101 to prevent the sample box 101 from colliding with the conical bottle during ultrasonic vibration, causing the bottle body to break and causing a safety accident.

[0041] The sample box 101 includes an upper shell and a lower shell that can be buckled with each other. The same first end of the upper shell and the lower shell is hinged and the same second end of the two is buckled through a first buckle mechanism 307. The buckled upper shell and the lower shell form an inner cavity for placing solid asphalt. The inner cavity wall is coated with an anti-sticking layer to prevent the asphalt from sticking inside the sample box 101 due to its high viscosity. A number of through holes are opened on the upper shell and / or the lower shell, and the dissolved asphalt is dispersed from the inner cavity of the sample box 101 to the outside through the several through holes. Among them, the lower shell is fixedly connected to the connecting frame 102, or the lower shell and the connecting frame 102 are an integrated structure.

[0042] The solid asphalt quantitative uniform dispersion ultrasonic mold provided by the present invention is provided by placing a quantitative amount of solid asphalt in each sample box 101, holding the support rod 2 and placing the connecting frame 102 into a conical flask filled with acetone solution, so that the acetone solution enters the sample ball, and placing the conical flask in an ultrasonic water bath for ultrasonication to allow the acetone solution to fully react with the solid asphalt. After the ultrasonication is completed, the connecting frame 102 is taken out. The above-mentioned setting can make the solid asphalt sample uniformly dispersed, and will not adhere to the sample box 101, so as to effectively carry out the subsequent root inhibitor extraction test.

[0043] Specifically, the anti-sticking layer can be made of anti-sticking materials such as polytetrafluoroethylene to prevent asphalt from sticking to the sample ball due to its high viscosity. At the same time, the sample box 101 with through holes allows the acetone solution to enter the sample ball, allowing the acetone solution to fully react with the solid asphalt.

[0044] In a specific embodiment, the number of sample boxes 101 is multiple, such as Figure 1 As shown, a plurality of sample boxes 101 are evenly arranged on a connecting frame 102. The connecting frame 102 with a plurality of sample boxes 101 allows the solid asphalt sample to be evenly distributed.

[0045] In a specific embodiment, the sample box 101 is a spherical structure, and further, a sample ball composed of a grid-like wall structure may be used. The connecting frame 102 is a plate-like structure.

[0046] In a specific embodiment, the first buckle mechanism 307 includes a buckle slot provided on the connecting frame 102 and a first buckle provided on the upper shell, and the first buckle is used to engage with the buckle slot. One side of the upper shell and the lower shell are connected by a hinge, and the other side is engaged by the first buckle mechanism 307. The first buckle mechanism 307 is set to lock, which can fix the position of the solid asphalt and prevent it from being released due to ultrasonic vibration.

[0047] The present invention further comprises an unlocking plate 4 and / or a locking plate 5, wherein the unlocking plate 4 is provided with grooves corresponding to the lower shells on the connecting frame 102 and protruding blocks corresponding to the slots on the connecting frame 102, and the locking plate 5 is provided with grooves corresponding to the upper shells on the connecting frame 102. When the sample box 101 is a spherical structure, the grooves of the unlocking plate 4 and the locking plate 5 are semi-spherical, and in particular, the diameter of the semi-spherical shape is larger than the diameter of the sample ball.

[0048] The unlocking plate 4 and the locking plate 5 are used as additional auxiliary tools. After placing the sample box 101, the upper locking plate 5 is used to buckle the upper shells of all sample boxes 101 on the same connecting frame 102; after the experiment is completed, the raised blocks on the unlocking plate 4 are used to open the upper shells of all sample boxes 101 on the same connecting frame 102 to increase the operating speed.

[0049] In this solution, by providing an unlocking plate 4 and a locking plate 5 , an inspector can lock and unlock a plurality of sample boxes 101 through a connecting frame 102 during the quantitative sample packaging process.

[0050] On the basis of the above specific embodiments, the present invention further comprises a main shaft plate 301 for connecting the support rod 2 and the connecting frame 102, and a plurality of connecting frames 102 are hingedly connected to the main shaft plate 301. The main shaft plate 301 can be made of Figure 5 The regular hexagon shown can, of course, also be any other regular polygon, circle or other shape. Multiple connecting frames 102 are hingedly arranged along the circumferential outer edge of the main axis plate 301. As long as the multiple connecting frames 102 can be opened and folded relative to the main axis plate 301, they are all within the protection scope of this case.

[0051] like Figure 7 As shown, the support rod 2 is detachably connected to the spindle plate 301 through the second buckle mechanism 305. The second buckle mechanism 305 includes a protrusion arranged on the support rod 2 and a second buckle arranged on the spindle plate 301. The protrusion is a strip structure. The second buckle is used to axially limit the long side of the protrusion, and the short side of the protrusion can be freely moved in the axial direction to achieve the separation of the support rod 2 and the spindle plate 301. That is, in the locked state, the bottom of the support rod 2 is buckled with the spindle plate 301, and the support rod 2 is rotated, and the second buckle mechanism 305 can be separated from or buckled with the hexagonal spindle plate 301.

[0052] Furthermore, the present invention further comprises a lifting rod 303 and a plurality of pull ropes 304. The first ends of the plurality of connecting frames 102 are hinged to the main shaft plate 301. The first ends of the pull ropes 304 are connected to the lifting rod 303, and the second ends of the pull ropes 304 are correspondingly connected to the second ends of the connecting frames 102. The lifting rod 303 is used to pull the plurality of connecting frames to open and close together. The mold telescopic, folding and opening functions provided by the present invention are suitable for conical bottles of various specifications during the test process.

[0053] The pull rope 304 can be a metal wire, or other materials.

[0054] The ends of the plurality of connecting frames 102 are connected to the main shaft plate 301 through the rotating shaft 302. In order to realize the lifting function, save the occupied space and facilitate the operation, the lifting rod 303 can be designed as a sleeve structure and sleeved on the support rod 2.

[0055] like Figure 4-Figure 6 As shown, the main shaft plate 301 is a regular hexagon, and its six sides correspond to a connecting frame 102 respectively.

[0056] In a specific embodiment, the second end of each pull rope 304 is detachably connected to the connecting frame 102 via a third buckle mechanism 306 .

[0057] The third buckle mechanism 306 includes a third buckle provided on the connecting frame 102 and a protrusion provided at the end of the pull rope 304. The third buckle is a U-shaped structure. The U-shaped notches of the third buckles on each connecting frame 102 are all facing the same side of the circumferential tangent direction.

[0058] The protrusion and the third buckle can be snap-fitted in the radial direction, and when rotating in the circumferential direction along the tangent direction of the notch, the snap-fitting state is released, and the connecting frame 102 device can be detached.

[0059] In a specific embodiment, the ultrasonic mold for quantitative and uniform dispersion of solid asphalt has 6 sample plates (i.e., the connecting frame 102), each sample plate has 6 sample balls (i.e., the sample box 101), the sample balls are made of anti-sticking material, in a grid shape, and have a first snap mechanism as a snap lock device. The 6 sample plates are distributed in a petal shape, and a rotating shaft 302 is installed between the sample plate and the hexagonal main shaft plate 301. The lifting rod 303 of the mold is connected to the third snap mechanism 306 using a metal wire, and the bottom of the support rod 2 is equipped with a second snap mechanism 305, which can be buckled with the hexagonal main shaft plate 301. The second snap mechanism 305 can be separated from or buckled with the hexagonal main shaft plate 301 by rotating the support rod 2. The bottom of the lifting rod 303 is equipped with 6 metal wires. Pulling the lifting rod 303 upward can fold the sample plate 90 degrees longitudinally, and pushing the lifting rod 303 downward can open the sample plate 180 degrees horizontally. After the sample plate is in a horizontal state, the buckle of the metal wire is separated from the sample plate, and the petal-shaped sample plate is immediately placed in a conical bottle to participate in the ultrasonic reaction. After the ultrasonic reaction is completed, the support rod 2 is rotated, and the protrusion of the second buckle mechanism 305 is pulled up from the bottom to buckle with the hexagonal main shaft plate 301, and the petal-shaped sample plate is folded 270 degrees in the longitudinal direction, and the sample plate is taken out.

[0060] The device is matched with a set of switch lock plates, wherein the lock plate 5 has 6 semicircular balls, and the diameter of the semicircular balls is 2mm larger than the diameter of the sample balls. It is used to press down to lock the 6 sample balls on the sample plate, and the unlocking plate 4 has 6 semicircular balls and a raised block, which is used to push up to unlock the first buckle mechanism of the six sample balls. The switch lock plate plays the role of quickly opening and closing the sample ball locking device, improving the efficiency of sample packaging.

[0061] The working process is as follows:

[0062] The inspector places the accurately weighed solid asphalt quantitatively in the lower shell of each sample ball, covers the upper shell of the sample ball, uses the locking plate 5 to place it above the sample plate, aligns the locking plate 5 with the sample ball hole, and locks multiple sample balls at the same time. Hold the lifting rod 303 and pull it upward to fold the petal-shaped sample plate inward, put the mold into the bottom position of the conical bottle, push the lifting rod 303 downward to open the petal-shaped sample plate, open the third buckle between the sample plate and the metal wire, and rotate the support rod 2 at the same time to disengage the second buckle mechanism 305 of the lifting rod from the hexagonal main shaft plate 301, remove the lifting rod 303 and the metal wire parts, and place the conical bottle in an ultrasonic water bath for ultrasonication. After the ultrasonication is completed, rotate the support rod 2, the second buckle mechanism 305 at the bottom is buckled with the hexagonal main shaft plate 301, and the petal-shaped sample plate is taken out. Place the unlocking plate 4 under the sample plate, align the raised block with the first snap mechanism of the sample ball, and push it upward to unlock multiple sample balls at the same time, and take out the solid asphalt for use.

[0063] In summary, the advantages of this solution's solid asphalt quantitative and uniform dispersion ultrasonic mold technology are:

[0064] 1. This mold ensures that the solid asphalt base does not clump and is quantitatively and evenly dispersed;

[0065] 2. This mold can ensure that the quantitatively and evenly dispersed solid asphalt base can fully react with acetone, thereby achieving an ideal extraction effect and the root inhibitor content can be precipitated normally.
