[0002] The chemical structure of asphalt emulsifier is composed of lipophilic groups and hydrophilic groups. It can be adsorbed on the interface between asphalt particles and water, thereby significantly reducing the free energy of the asphalt-water interface, making it a surfactant that constitutes a uniform and stable emulsion. When a small amount is added, the surface tension of water can be greatly reduced, and the interfacial properties and state of the system can be significantly changed, thereby producing a series of effects such as wetting, emulsification, foaming, washing, dispersion, antistatic, lubrication, and solubilization to meet the requirements of practical applications. In the preparation process of asphalt emulsifier, heating is required to mix the raw materials.

[0027] The electric push rod 9 is started by the controller 4, and the telescopic end of the electric push rod 9 drives the hardness display instrument 17 to move, and the hardness display instrument 17 drives the detection head 8 to detect the internal asphalt emulsifier, thereby ensuring the convenience and accuracy of the detection. When the detection head 8 and the hardness display instrument 17 need to be replaced, the nut 16 is turned to remove the fixing bolt 15, so that the first mounting plate 19 is separated from the second mounting plate 18, so that the detection head 8 can be disassembled and replaced, thereby ensuring the maintenance and maintenance of the hardness detection device and ensuring the continuous detection.
[0028] Reference Figure 1 , Figure 2 and Figure 5 The clamping assembly includes a fixing plate 3, which is fixedly connected to both sides of the upper part of the placing plate 7. A pull rod 20 is arranged inside the fixing plate 3, and the inner side of the pull rod 20 is fixedly connected to the clamping plate 2. A pull block 25 is fixedly connected to the outside of the pull rod 20. A spring 26 is arranged outside the pull rod 20, and the spring 26 is arranged on the inner side of the fixing plate 3. The outer front side of the clamping plate 2 is fixedly connected to a limiting plate 24, and a limiting hole 23 is arranged inside the limiting plate 24. Two connecting plates 21 are fixedly connected to the outer front side of the fixing plate 3, and an inserting rod 22 is arranged inside the connecting plate 21.
[0029] By pulling the pull block 25, the pull block 25 drives the pull rod 20 to move outward, and at the same time squeezes the spring 26 to place the asphalt emulsifier barrel on the inner side of the clamping plate 2, and then releases the pull block 25. The clamping plate 2 clamps the asphalt emulsifier barrel through the reaction force of the spring 26. After the inspection is completed, pull the pull block 25 again to make the limit plate 24 slide into the interior of the fixed plate 3, and insert the insertion rod 22 inside the connecting plate 21 into the limit hole 23 inside the limit plate 24 to fix it, thereby releasing the clamping of the asphalt emulsifier barrel.
[0030] Reference Figure 1 and Figure 3A chassis 11 is provided at the four corners of the bottom of the workbench 6, a threaded rod 12 is fixedly installed on the top of the chassis 11, a threaded mounting sleeve 5 is movably installed on the outer wall of the threaded rod 12, a first sealed bearing 14 is fixedly installed on the inner wall of the threaded mounting sleeve 5, a connecting rod 13 is fixedly installed on the inner wall of the first sealed bearing 14, the connecting rod 13 is fixedly connected to the four corners of the bottom of the workbench 6, and a horizontal bubble meter 10 is fixedly connected to the bottom of the workbench 6;
