Description

Technical Field

[0001] This invention relates to a foaming device for foamed asphalt, belonging to the technical field of asphalt processing equipment. Background Technology

[0002] Foamed asphalt refers to asphalt produced by adding a certain amount of cold water to high-temperature asphalt. When the water is heated, it rapidly vaporizes and mixes with the asphalt, forming explosive foam. This causes the surface area of ​​the asphalt to increase significantly, its volume to expand several times to tens of times, and its viscosity to decrease. The asphalt foam bursts, leaving only a small number of microbubbles. This type of asphalt that expands into foam is called foamed asphalt.

[0003] After asphalt is foamed by a foaming device, the device is equipped with a stirring structure to mix water and asphalt. However, during the mixing process, the timing of adding water and asphalt is often incorrect, resulting in uneven mixing and insufficient contact between water and asphalt. Water and asphalt cannot be added simultaneously, leading to poor foaming effect and affecting subsequent use. Therefore, it is necessary to design a foaming device for foamed asphalt to solve the above problems. Summary of the Invention

A connecting cylinder is provided on the top of the mixing furnace, and a feed hopper is provided directly above the connecting cylinder. A limiting installation groove is formed on the top of the mixing furnace, and lugs are provided on the side of the connecting cylinder. The bottom of the connecting cylinder is inserted into the limiting installation groove, and the lugs are fixedly connected by bolts. The mixing furnace and the connecting cylinder are connected internally, allowing asphalt to enter the mixing furnace from the connecting cylinder. Multiple guide pipes are symmetrically and fixedly installed through the top of the side of the connecting cylinder, and the bottom of the feed hopper is connected through... The device has multiple discharge ports, and the tops of multiple guide pipes are fixedly connected to the discharge ports via flanges, allowing for disassembly and assembly for convenient periodic cleaning of each part. The top of the connecting cylinder is fitted with a cover plate, which is fixedly connected to the connecting cylinder with bolts. A water inlet pipe is vertically inserted into the center of the cover plate, and the top of the water inlet pipe is connected to a water pump and water source via a connector, which can guide water into the connecting cylinder. A vertical pipe is fixedly installed through the bottom of the water inlet pipe, and the top of the vertical pipe is fixedly connected to the cover plate with bolts. The vertical pipe has multiple water outlet holes, which can discharge water into the connecting cylinder.

[0006] Preferably, a threaded block is installed at the bottom of the vertical pipe by threads, and a post is fixedly installed at the top center of the threaded block. The post is located inside the vertical pipe, which can reduce the internal space of the vertical pipe and increase the pressure at the water outlet. A rotating block is fixedly installed at the bottom of the threaded block, and the rotating block is provided with anti-slip texture to facilitate the rotation of the threaded block for disassembly and cleaning of the inside of the vertical pipe.

[0007] Preferably, the bottom of the feed hopper is configured with a raised structure, which is a cone shape, so asphalt will not accumulate and can be discharged from the feed hopper.

[0008] Preferably, the water outlet is configured in several rows, and the several rows of water outlets are respectively corresponding to the guide pipe, so that they can contact the asphalt flowing out of the guide pipe and the contact is relatively sufficient.

[0009] Preferably, the cover plate has multiple air outlets arranged in a ring array to discharge the high-temperature water vapor generated by the contact between water and high-temperature asphalt, thereby reducing the internal pressure and ensuring smooth operation.

[0010] Preferably, the mixing furnace has multiple side holes, and two annular sleeves are fixedly fitted on the outer side of the mixing furnace, with the two annular sleeves located above and below the side holes respectively, which can protect the side holes.

[0011] Preferably, multiple vertical rods are fixedly installed between the two annular sleeve plates, and the multiple vertical rods are arranged in a circular array. Protective mesh is fixedly wrapped around the periphery of the multiple vertical rods to prevent foreign objects from entering.

[0012] Preferably, the bottom of the mixing furnace is provided with multiple discharge ports, and discharge components are fixedly installed at the bottom of the multiple discharge ports to control the discharge.

[0013] Preferably, the discharge assembly includes a discharge frame, which is fixedly installed on the lower surface of the mixing furnace. A baffle is horizontally inserted into the discharge frame, and two horizontal guide frames are symmetrically fixedly installed on one side of the discharge frame. One end of the horizontal guide frame extends into the interior of the discharge frame. The baffle is disposed between the two horizontal guide frames. A pull bracket is fixedly installed on one side of the baffle. One end of the pull bracket is ring-shaped and can be pushed and pulled to move the baffle laterally. This controls the discharge and the discharge speed, as well as the discharge position, and facilitates receiving.
