Description

Technical Field

[0001] This utility model relates to the field of asphalt additive injection technology, specifically to an easily dispersed, direct-dispensing high-modulus asphalt additive injection device. Background Technology

[0002] In the field of road engineering, high-modulus asphalt is widely used in the paving and maintenance of highways and heavy-duty roads due to its excellent high-temperature stability and rutting resistance. Achieving the performance of high-modulus asphalt relies on the precise addition of specific asphalt additives to optimize key indicators such as viscoelasticity and durability. However, existing asphalt additive injection processes have many shortcomings, driving technological innovation in injection equipment.

[0003] High-modulus asphalt additives are mostly powders or mixtures of high-viscosity particles, which are prone to agglomeration and poor dispersibility. Conventional injection equipment lacks a targeted dispersion structure, causing additives to easily clump and accumulate during application. This results in uneven distribution of additives in the asphalt mixture, which not only fails to fully realize the high-modulus modification effect but may also lead to early pavement defects such as cracking and rutting due to excessive or insufficient additives in certain areas, seriously affecting the service life of roads and driving safety. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model achieves the following technical solution: a high-modulus asphalt additive injection device for easy dispersion and direct injection, comprising: an injection assembly, a motor fixedly installed at the middle of the top of the injection assembly, a hopper fixedly installed on one side of the top of the injection assembly, a conveying chamber fixedly installed at the bottom of the injection assembly, a discharge pipe fixedly installed on the outer surface of the conveying chamber, a moving assembly fixedly installed at the bottom of the conveying chamber, a storage chamber fixedly installed on the outer surface of the moving assembly, and a guide pipe fixedly installed on the surface of the storage chamber, the guide pipe being fixedly connected to the injection assembly; the storage chamber is connected to the injection assembly through the guide pipe and can store liquids for cleaning, mixing, etc., and guide them to the injection assembly as needed. The dispersed material falls into the bottom of the conical tank and enters the conveying chamber. Utilizing the structure of the conveying chamber itself, such as a possible internal conveying mechanism, combined with the discharge pipe, directional conveying is achieved, and the material is discharged through the discharge pipe, allowing for precise delivery to target locations such as asphalt processing.

[0005] The injection assembly includes a conical tank with a threaded top cover. A dispersing component is rotatably mounted inside the conical tank, and an extension rod is rotatably mounted at the bottom of the dispersing component. A material-distributing strip is fixedly mounted on the surface of the extension rod. The operator adds high-modulus asphalt additive to the conical tank through a hopper on one side of the top of the injection assembly. The motor at the top center is activated, and its output drives the dispersing component to rotate inside the conical tank. Simultaneously, the extension rod and material-distributing strip at the bottom of the dispersing component rotate synchronously. The material-distributing strip rubs against the inner wall of the conical tank, initially distributing and dispersing the material inside to prevent accumulation.

[0006] Preferably, the conical tank is fixedly installed on the top of the conveying chamber, the top cover is fixedly connected to the motor, the output end of the motor passes through the top cover and is fixedly connected to the dispersing component, and the feeding strip is frictionally adapted to the inner wall of the conical tank.

[0007] Preferably, the dispersing component includes a stirring shaft with a mounting groove on its surface. A support rod is fixedly installed inside the mounting groove. Several support rods are arranged in a circumferential pattern inside the mounting groove and have a double-layer structure. An inner ring and an outer ring are fixedly installed on the surface of each support rod, and a deflector plate is fixedly installed between the opposite faces of the outer rings. The multi-layered, multi-structure design of the deflector plate and support rods, combined with the material-dispersing strip, ensures thorough mixing and dispersion of the asphalt additive, preventing agglomeration and clumping, ensuring smooth subsequent conveying and injection processes, improving injection accuracy and stability, and guaranteeing uniform mixing of the additive during asphalt processing.

[0008] Preferably, the stirring shaft is fixedly connected to the output end of the motor, and the bottom of the stirring shaft is fixedly connected to the extension rod.

[0009] Preferably, the mobile component includes a base, with wheels fixedly mounted on the bottom of the base, and guide rails fixedly mounted on the surface of the base. A support plate is slidably mounted inside the guide rails. The wheels facilitate the overall movement of the device and adjustment of its working position. The guide rails cooperate with the support plate, which can slide below the discharge pipe to adapt to different discharge heights and positions, assisting in the stable receipt and transfer of materials. It also facilitates connection with other equipment, enhancing the device's versatility. The wheels allow the device to be flexibly moved to different work sites, adapting to various asphalt production and construction scenarios.

[0010] Preferably, the base is fixedly installed at the bottom of the conveying chamber, and the support plate is disposed below the discharge pipe.

[0011] This invention provides an easily dispersed, direct-dispensing high-modulus asphalt additive injection device. It has the following beneficial effects:

[0012] (i) This easily dispersed, direct-dispensing high-modulus asphalt additive injection device connects to the injection assembly via a storage chamber and a delivery pipe. It can store liquids used for cleaning and preparation, and deliver them to the injection assembly as needed. The dispersed material falls to the bottom of the conical tank and enters the conveying chamber. Utilizing the conveying chamber's own structure, such as an internal conveying mechanism, and combined with the discharge pipe, directional conveying is achieved. The material is then discharged through the discharge pipe, allowing for precise delivery to target locations such as asphalt processing areas.

[0013] (II) This easily dispersible, direct-dispensing high-modulus asphalt additive injection device, by starting the motor in the middle of the top, drives the dispersing component to rotate inside the conical tank. Simultaneously, the extension rod and material-distributing strip at the bottom of the dispersing component rotate synchronously. The material-distributing strip rubs against the inner wall of the conical tank, which can initially distribute and disperse the material in the tank, avoiding accumulation. The dispersing component's dispensing plate, frame rod, and other structures feature a multi-layered, multi-structure design, which, together with the material-distributing strip, fully stirs and disperses the asphalt additive, preventing the additive from agglomerating and clumping, ensuring smooth subsequent conveying and injection processes, improving injection accuracy and stability, and ensuring uniform mixing of the additive during asphalt processing.

[0014] (III) This easily dispersed, direct-dispensing high-modulus asphalt additive injection device features wheels on its movable components for convenient overall movement and adjustment of the working position. The guide rails and support plates work together, with the support plate sliding beneath the discharge pipe to accommodate different discharge heights and positions, facilitating stable material reception and transfer.
