Description

Technical Field

[0001] This utility model relates to the field of foaming equipment technology, specifically to a foaming equipment for road asphalt paving. Background Technology

[0002] Foaming equipment for road asphalt paving is a device specifically designed for preparing foamed asphalt. It plays an important role in road construction. The inner wall of the cylinder is equipped with electric heating elements to heat the asphalt, ensuring that the asphalt maintains an appropriate temperature during processing. Foaming equipment for road asphalt paving is a highly efficient and practical road construction equipment. By optimizing the mixing and foaming process, it improves the quality and construction efficiency of foamed asphalt.

[0003] According to publication number CN217021183U, a foaming device for warm-mix foamed asphalt is disclosed. Addressing the problems of existing methods that directly add water nozzles from above, leading to water vaporization easily trapping small particles and clogging the nozzles; uneven foaming due to water only contacting the asphalt surface; and the complexity of adding a water volume control and temperature acquisition system, the following solution is proposed: It includes a rectangular box with an inlet pipe on the left and an outlet pipe on the right. A protective shell is installed on the right side of the rectangular box, and a servo motor is installed inside the protective shell. A drive shaft is mounted on the output shaft of the servo motor. In this invention, water is atomized and mixed with hot asphalt, rather than simply sprayed onto the surface. The water nozzle has a flow meter and an internal temperature acquisition probe to control the water output and monitor the asphalt temperature in real time, improving the completeness of foaming, increasing the production efficiency and product quality of foamed asphalt, and ensuring uniform foaming. The following problems exist with the existing technology:

[0004] However, during the mixing process, raw materials may accumulate at the bottom and cannot be mixed. The existing device cannot fully mix the raw materials inside the device. Furthermore, the inside of the discharge pipe is not cleaned while the device is in use. After the mixing is finished, these raw materials will adhere to the inner wall of the discharge pipe and eventually clump together, affecting the normal discharge next time. Utility Model Content
