Description

Technical Field

[0001] The utility model relates to the technical field of asphalt processing, in particular to a modified asphalt additive feeding device. Background Technique

[0002] The main purpose of adding modifiers to asphalt is to improve the road performance of asphalt mixtures at high temperatures. Asphalt modifiers refer to natural or synthetic organic or inorganic materials added to asphalt or asphalt mixtures, which can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt. For example, in order to improve the mechanical properties (strength and toughness, etc.) of asphalt, materials such as polymers, resins, plastics, carbon black, and inorganic salts that increase strength and toughness are added. During the production process of modified asphalt, a modified asphalt additive feeding device is often required to add a certain modified asphalt stabilizer to the asphalt processing device to improve the storage stability of the modified asphalt.

[0003] Existing modified asphalt additive feeding devices still have deficiencies, specifically as follows: they do not have an anti-blocking feeding structure and a feeding flow measurement and control structure, so it is not convenient to rotate and turn the additives to prevent them from blocking the feed pipe of the feeding mechanism. At the same time, it is not convenient to monitor the feeding additive flow in real time by microwave for accurate metering feeding, so continuous feeding with accurate metering and high-efficiency anti-blocking cannot be achieved.

[0004] Therefore, it is necessary to design a modified asphalt additive feeding device to solve the problems in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to provide a modified asphalt additive feeding device to solve the problems put forward in the above background technique.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the anti-blocking impeller provided by the feeding mechanism can rotate and turn over the additive under the drive of the second motor when the additive stored in the sealed main body of the feeding device is fed through the electric valve pipe, so as to prevent the additive from blocking the feed pipe of the feeding mechanism, thereby realizing efficient anti-blocking continuous feeding.
