Plant-mixed heat regeneration equipment with cold adding function and production method thereof

Abstract

The utility model discloses plant-mixed heat regeneration equipment with a cold adding function. The plant-mixed heat regeneration equipment comprises a coarse aggregate conveying system, a coarse aggregate drying and heating system, a fine aggregate conveying system and a reclaimed material conveying device, the coarse aggregate drying and heating system comprises a regeneration drying roller, acombustion device and a tail gas treatment device, the regeneration drying roller is obliquely arranged, the tail end of the coarse aggregate conveying system is connected to the high position of theregeneration drying roller, a discharging box is arranged at the low position of the regeneration drying roller, and a coarse aggregate temporary storage bin is connected to the lower portion of the discharging box; the fine aggregate conveying system comprises a fine aggregate bin, a fine aggregate belt conveyor, a fine aggregate elevator and a fine aggregate conveying device, a fine aggregate temporary storage bin is arranged at the discharging end of the fine aggregate conveying device, a measuring scale is arranged below the fine aggregate temporary storage bin and the coarse aggregate temporary storage bin, and a reclaimed material conveying device is arranged below the measuring scale. Separate conveying and heating of coarse aggregate and fine aggregate can be achieved, the adhesiondegree of a regeneration drying roller and the like is reduced, the equipment shutdown risk is reduced, and the use performance of equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of asphalt mixture heat regeneration equipment, in particular to a plant mix heat regeneration equipment with cold addition function and a production method thereof. Background technique [0002] Asphalt mixture thermal recycling technology is a technology to recycle waste asphalt mixture. In the existing plant-mixed heat regeneration technology, the cold waste asphalt mixture of various grades is sent to the drying heating system at the same time for drying and heating treatment, and then mixed with a certain proportion of new aggregate, asphalt, mineral powder, etc. Mixing, and finally produce qualified asphalt mixture finished material. However, there are the following problems in this plant-mixed heat regeneration method: [0003] 1. Coarse and fine aggregates in waste asphalt mixture enter the drying drum at the same time for heating. It is difficult to ensure the uniformity of heating of coarse and f...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a plant-mix heat regeneration equipment with cold-addition function and its production method. Its main purpose is to solve the problem that the waste asphalt mixture enters the drying drum to be heated at the same time in the existing plant heat-mix heat regeneration, which causes the asphalt on the surface of the fine material to age. Seriously, the asphalt on the surface of the fine aggregate is very easy to adhere to the drying drum and other parts, resulting in the failure of the equipment to operate normally.
