Description

A kind of inclined epoxy emulsified asphalt cold patch mixing device

technical field

The utility model belongs to the field of pavement material processing, in particular to an inclined type epoxy emulsified asphalt cold patch mixing device.

Background technique

In the existing epoxy emulsified asphalt cold patching mixture and its application research, the preparation method is as follows: firstly add the coarse and fine aggregates into the mixing equipment to mix evenly, then add the required amount of mixing water, and mix until the aggregate surface is completely wet. , then add the required amount of epoxy emulsified asphalt, continue to mix for about 1min, then add mineral powder, continue to mix until the mixture is uniform, and finally the finished product is obtained. The mixing equipment generally refers to the asphalt mixing building.

The traditional asphalt mixing building is vertical, with vibrating screen, hot aggregate silo, metering and mixing system, finished product silo, discharge layer, etc. arranged from top to bottom. The height of traditional asphalt mixing building can generally reach more than 28m. For example, the latest Deji 5000 asphalt mixing building has a height of 30m. This top-to-bottom arrangement has many disadvantages. For example, the weight is too concentrated and the foundation strength is very high, which is not conducive to the construction of the plant; It is transported to mid-air from ground storage bins, mineral powder storage tanks and asphalt storage tanks, resulting in a lot of unnecessary energy consumption; the height of the vibrating screen is too high, and there is a risk of falling when the mineral material vibrates, posing a threat to production safety.

The existing asphalt mixing building includes the main building, the auxiliary building and the carrying device. The traditional asphalt mixing building is transformed into the main building and the auxiliary building, and connected by the carrying device, so that the height of the mixing building is reduced by about half. The height is still more than 15m, which fails to fully solve the problems of energy consumption, production safety and excessive weight concentration.
