Description

Technical Field

[0001] This utility model relates to the field of asphalt production and processing technology, and more specifically, to a colloid mill for automated processing of emulsified asphalt. Background Technology

[0002] Emulsified asphalt is an extremely complex and unique material. It's not simply a random mixture of asphalt, water, and emulsifiers; rather, it undergoes a series of specific, meticulous processes and is processed using specialized equipment to ultimately create a stable emulsion system. In this process, asphalt, as the primary solid component, directly determines the basic properties of the emulsified asphalt through its quality and characteristics. Water, as the liquid phase, provides the necessary fluidity and dispersion medium. The emulsifier plays a crucial bridging role, successfully enabling the originally incompatible asphalt and water to coexist harmoniously thanks to its unique hydrophilic and lipophilic properties. Through careful processing, the asphalt is dispersed into fine particles, uniformly and stably suspended in the water, creating the unique material that is emulsified asphalt.

[0003] In the processing of emulsified asphalt, the colloid mill plays a crucial role. Its main function is to finely grind and shear the asphalt, breaking it into extremely small particles and dispersing them evenly in an aqueous solution containing emulsifiers. Through the high-speed operation and strong shearing force of the colloid mill, the asphalt particles are fully integrated with water and emulsifiers to form a stable emulsified asphalt emulsion.

[0004] Under current technological conditions, when processing emulsified asphalt using a colloid mill, the mill is first preheated with hot water. Then, asphalt and soap solution are manually batched and fed into the mill at a uniform rate. Finally, by adjusting the mill's rotation speed and feed rate, standard-compliant emulsified asphalt is produced. However, the following problems mainly exist in the above process:

[0005] First, relying on manual mixing of asphalt and soap solution makes it difficult to accurately control the ratio of asphalt and soap solution, resulting in inconsistent product quality.

[0006] Secondly, the heating method of using hot water to preheat the colloid mill results in a rapid cooling rate, making it difficult to ensure that the colloid mill remains in a constant temperature environment for a long period of time.

[0007] Today, the market demands for the performance of emulsified asphalt colloid mills are increasing daily. Therefore, developing a new type of automated emulsified asphalt colloid mill, aiming to solve the problems existing in traditional equipment and improve production efficiency, product quality, and automation level, has significant practical importance and application value.

Detailed Implementation

[0035] Example 1

[0036] Please refer to Figures 1-3 This application provides an automated colloid mill for processing emulsified asphalt, comprising a colloid mill body, a temperature control component, a first pre-feeding component, a second pre-feeding component, and a control component. The colloid mill body includes a grinding chamber 3 with an inlet and an outlet. The grinding chamber 3 contains a grinding disc assembly (composed of cooperating stationary and moving grinding discs). A feed hopper 1 is located at the inlet of the grinding chamber 3, and a discharge pipe 25 is located at the outlet. The moving grinding discs of the grinding disc assembly are connected to a first drive motor 2. Material is fed into the grinding chamber 3 through the feed hopper 1, where the cooperation of the moving and stationary grinding discs shears and processes the material, which is then output through the discharge pipe 25.

[0037] Furthermore, the temperature control component consists of an electric heating structure and a first temperature sensor 26. The electric heating structure is used to heat the internal space of the grinding chamber 3, and the first temperature sensor 26 is used to monitor the temperature value of the internal space of the grinding chamber 3 in real time. The first pre-feeding component includes a soap solution mixing tank 7, a first electronic weighing device 14, a first electronic flow meter 17, and a first feed pipe 19. The first electronic weighing device 14 is used to monitor the weight of the soap solution mixing tank 7, the first feed pipe 19 is used to guide the soap solution from the soap solution mixing tank 7 to the feed hopper 1, and the first electronic flow meter 17 is used to monitor the flow rate of the first feed pipe 19. The second pre-feeding assembly includes an asphalt storage tank 8, a second electronic weighing device 15, a second electronic flow meter 18, and a second feed pipe 20. The second electronic weighing device 15 is used for weight monitoring of the asphalt storage tank 8, the second feed pipe 20 is used for guiding the asphalt from the asphalt storage tank 8 to the feed hopper 1, and the second electronic flow meter 18 is used for monitoring the flow rate of the second feed pipe 20. The assembly also includes a control component, including a PLC controller 21. The electric heating structure, the first temperature sensor 26, the first electronic weighing device 14, the first electronic flow meter 17, the second electronic weighing device 15, and the second electronic flow meter 18 are all electrically connected to the PLC controller 21.

[0038] In the practical application of this application, firstly, based on the coordinated operation of the PLC controller, the electric heating structure, and the first temperature sensor 26, the electric heating structure preheats the colloid mill body in a water bath, and the first temperature sensor 26 monitors the temperature of the grinding chamber 3 in real time and feeds back the monitored temperature value to the PLC controller. When the temperature is too high or too low, the PLC controller will prompt the electric heating structure to make corresponding adjustments to ensure that the grinding chamber 3 can maintain a constant temperature value (or a specific temperature range) for a long time, thereby ensuring a good processing environment for the emulsified asphalt. Secondly, based on the coordinated operation of the PLC controller, the first electronic weighing device 14, the first electronic flow meter 17, the second electronic weighing device 15, and the second electronic flow meter 18, automated control of the soap solution and asphalt ratio can be achieved, ensuring the accuracy of the proportion of each component in the emulsified asphalt, thereby improving the overall quality of the product.

[0039] Specifically, the aforementioned control components also include an LED display screen 22 and an operation panel 23, both electrically connected to the PLC controller. The LED display screen 22 can display data from various electronic components (electric heating structure, first temperature sensor 26, first electronic weighing device 14, first electronic flow meter 17, second electronic weighing device 15, and second electronic flow meter 18). The operation panel 23 allows for the editing of predetermined data from the PLC. This predetermined data includes the threshold values ​​for the first temperature sensor 26, the first electronic weighing device 14, the first electronic flow meter 17, the second electronic weighing device 15, and the second electronic flow meter 18.

[0040] The first drive motor 2 and the PLC controller 21 are electrically connected to adjust the shearing time and rate of the grinding disc assembly.

[0041] The colloid mill described in this application achieves automated processing control of emulsified asphalt, a significant innovation. It replaces traditional manual adjustment methods, significantly reducing the physical labor intensity for workers. Previously, workers had to expend considerable energy on tedious adjustment operations; now, this high-intensity physical exertion is greatly reduced. Simultaneously, it lowers safety hazards in the working environment. Traditional manual adjustment involves numerous uncertainties and potential dangers, while automated control largely avoids these problems. Now, workers only need to perform simple monitoring and maintenance to complete the complex emulsified asphalt preparation process, not only improving work efficiency but also ensuring a safe working environment, thus positively promoting the development of related industries.

[0042] In some embodiments of this utility model, the above-mentioned electric heating structure includes a heat conductor 4 and a first heating wire disposed inside the heat conductor 4. The heat conductor 4 is disposed in the grinding chamber 3, and the first heating wire is electrically connected to the PLC controller 21.

[0043] In the above embodiment, the PLC controller presets the threshold of the first temperature sensor 26. When the measured data of the first temperature sensor 26 is greater than or less than this preset threshold, the PLC controller will play a regulating role and adjust the output power of the first heating wire (the power supply can be adjusted), thereby achieving precise temperature control of the grinding chamber 3.

[0044] Preferably, the heat conductor 4 is made of a high-quality thermally conductive material. This material can efficiently transfer the heat generated by the first heating wire to the grinding chamber 3. In this way, not only can the water be preheated, but the grinding chamber 3 can also be effectively insulated, ensuring that the grinding chamber 3 can be maintained at a constant temperature for a long period of time, creating ideal conditions for the processing of emulsified asphalt.

[0053] In the above embodiment, the second temperature sensor 27 can monitor the material temperature in the soap mixing tank 7 or the asphalt storage tank 8 in real time. When the material temperature in the soap mixing tank 7 or the asphalt storage tank 8 exceeds the preset threshold of the PLC controller 21, the PLC controller 21 adjusts the second heating wire 13 to achieve temperature regulation of the material in the soap mixing tank 7 or the asphalt storage tank 8.

[0054] In some embodiments of this utility model, a PLC controller 21 electrically connected to the above-mentioned PLC controller 21 is also included, which is used to monitor the pH value of the soap solution in the above-mentioned soap solution mixing tank 7.

[0059] In some embodiments of this utility model, the base 24 is further provided with a plurality of material storage tanks 10 for storing asphalt, water or emulsifier.

[0060] In the above embodiment, there are three material storage tanks, which are used to store asphalt, water and emulsifier respectively. When the corresponding raw materials (asphalt, water or emulsifier) ​​are insufficient, they can be added and replenished in time.
