Description

Technical Field

[0001] The utility model relates to the technical field of emulsified asphalt production and processing, in particular to an emulsified asphalt colloid mill device with the characteristics of integrated preparation and storage. Background Art

[0002] At present, my country can be said to be a veritable highway power. By the end of 2022, the total mileage of highways in my country has reached 5.3548 million kilometers, including 177,300 kilometers of expressways. In the huge highway network, asphalt pavement accounts for a large proportion, especially expressways, which even account for more than 90%. With the increase in service life, most of the asphalt roads built in the early days have entered the maintenance stage. At present, asphalt road maintenance is mainly preventive maintenance, and the maintenance material is mainly emulsified asphalt. Emulsified asphalt has the characteristics of laying at room temperature, which can provide a good construction environment for road builders and can well overcome the influence of construction seasons. Therefore, emulsified asphalt is widely used in road repair and maintenance projects.

[0003] Emulsified asphalt is a room temperature liquid in the state of "oil-in-water" or "water-in-oil" formed by high-temperature asphalt and emulsifier soap solution under the action of high-speed shear. The preparation of emulsified asphalt is divided into factory preparation and laboratory preparation. Factory preparation adopts an integrated continuous colloid mill, while laboratory preparation usually uses a small colloid mill for preparation. The preparation process is preheating asphalt-preparing emulsifier soap solution-emulsification-storing emulsified asphalt. In the current preparation process, the emulsification step requires the soap solution and asphalt to be poured slowly at the same time, stirring while pouring. However, since the colloid mill is relatively small and only suitable for one person to operate, many users directly pour the soap solution completely and then slowly pour the asphalt. Although this is convenient for operation, the quality of the prepared emulsified asphalt is still somewhat different from the former. When the asphalt emulsion is emulsified in the colloid mill, the temperature is usually as high as about 90°C, resulting in a high surface temperature of the circulation pipe, which is prone to scalding. Since the traditional colloid mill has no receiving system, the prepared emulsion can only be received by a handheld storage device, which is not conducive to operation and is prone to scalding.

[0004] In view of this, it is necessary to design an emulsified asphalt colloid mill device with integrated preparation and storage features to solve the above problems. Utility Model Content

[0036] The working principle of the emulsified asphalt colloid mill device with integrated preparation and storage characteristics provided by the utility model is described below in conjunction with specific embodiments:

[0037] First, prepare the asphalt and soap solution, put the asphalt sample into the oven and heat it to about 145℃ for 1 hour to keep it flowing and ensure that the asphalt temperature also reaches about 145℃; add clean water to the additional feed hopper 4, set the temperature of the temperature control screen 42 to 65℃, and control the liquid volume through the volume scale 46. After the temperature reaches 65℃, keep it warm and add organic stabilizer, emulsifier, inorganic stabilizer, etc. in sequence and stir evenly. Take out the asphalt, start the machine, open the additional feed hopper control valve 43 of the additional feed hopper 4 and pour the asphalt. The asphalt and emulsion are emulsified through the grinding system 2 and the circulation system 3. During the emulsification process, use a glass rod to stir continuously in the storage bin 8, stirring while pouring. After the soap solution and asphalt are poured, emulsify for a certain period of time and add water to the additional feed hopper 4 and heat it. The emulsified emulsified asphalt enters the three-way port 5, the diversion control valve 52 is opened, the emulsified emulsified asphalt is connected to the storage tank 63 through the emulsified asphalt discharge port 51, the storage tank is covered, the temperature knob 64 and the magnetic rotor knob 65 are turned on, the temperature is set to 60°C, and the magnetic rotor 62 is turned on for stirring. Pour part of the emulsifier into the storage bin 8, open the circulation and discharge control valve 7, and put in part of the hot water for cleaning. The emulsifier is added for the first time, and no emulsifier is added for the next two times. The waste liquid flows into the waste liquid barrel through the waste liquid discharge port 53 and the waste liquid hole. After about 30 minutes of cleaning, the temperature knob 64 is turned off. During the process, the storage tank 63 remains closed. After 45 minutes, when the emulsified asphalt cools to room temperature, the magnetic rotor 62 stops rotating through the magnetic rotor knob 65, and the emulsified asphalt is prepared.

[0038] In summary, the utility model provides an additional feed hopper 4 to achieve simultaneous addition of soap liquid and asphalt into the storage bin for shearing, and a heating conduit 41 is provided in the additional feed hopper 4. The heating conduit 41 can keep the soap liquid warm and heat the cleaning liquid during the asphalt emulsification process to ensure that cleaning can be performed immediately after the asphalt emulsification is completed. By setting the circulation conduit 3 as a vacuum double-layer conduit, it is ensured that the high temperature of the inner conduit 31 is not transmitted to the outer conduit 32, and the experimenter is not scalded. By providing a magnetic device at the discharge port to hold the storage tank 61, and providing a three-way port at the discharge port to separate the discharge port from the wastewater port, and providing a waste liquid hole at the wastewater port, the cleaning waste liquid can flow out smoothly, and by providing a magnetic device under the storage tank 61, the high-temperature emulsion can be automatically stirred by the magnetic rotor 62.
