Description

Technical Field

[0002] Currently, in the production process of special asphalts such as rubber powder asphalt, cable asphalt, and sealant, the common method is to first heat the asphalt to a certain temperature through a heat exchanger and then pump it into a batching tank. Then, the additives are directly pumped into the batching tank according to the ratio through a material elevator. After being fully mixed with the asphalt, the mixture enters the next production process. The additives are mostly of multiple types. When adding asphalt powder, the existing feeding methods are generally divided into two types: one is to manually add asphalt additives, and the other is to transport them through a conveying pipeline to achieve the feeding effect.

[0003] For example, the auxiliary material addition mechanism in the asphalt production equipment disclosed in the authorization announcement number CN218486054U includes a tank, a feed hopper and a discharge pipe.

The auxiliary materials poured into the crushing mortar are automatically crushed. The crushed auxiliary materials are easier to mix with asphalt, which solves the problem that the large volume of blocky auxiliary materials makes it difficult to mix and react with asphalt.

This greatly affects the dispensing range, the accuracy of dispensing, and the convenience of adjusting the dispensing position. Utility Model Content
