Hot-in-place regenerative remixer scale plate conveyor

Abstract

The invention provides a scale plate conveyer of a local thermal regeneration remixer. The conveyer can realize cyclic utilization of heat energy and avoid the heat loss and is strong in transportation capability. The scale plate conveyer of the local thermal regeneration remixer comprises a milling drum, a rack body and a conveying material mechanism, and further comprises a circulatory heating mechanism which comprises a housing, a combustion chamber, a combustor, a heating hood and a fan, wherein the housing is arranged above the rack body, a hot wind cavity is formed in the housing, an air outlet is formed at the upper end, an air return opening is formed at the lower end, and air outlet holes are uniformly distributed at the bottom, so that an air flow is sprayed to a scale plate on the side of the air outlet holes; the combustion chamber is arranged in the housing; the combustor is arranged at the front end of the combustion chamber; the heating hood is arranged below the combustion chamber and is provided with an air return channel; the air inlet is communicated with the air return channel and the air outlet is communicated with the combustion chamber; a hot wind inlet communicated with the air outlet holes is formed in the side face at the upper end of the rack body.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a scale-plate conveyor of an in-situ heat regeneration remixer. Background technique [0002] At present, most highways in my country discard a large amount of milling materials in the process of asphalt pavement maintenance, which not only destroys the environment, wastes resources, but also increases costs. The hot-in-place recycling process of asphalt pavement is a new process for asphalt pavement maintenance and construction. This process regenerates the old asphalt pavement in situ and can utilize 100% of the original old asphalt pavement materials. The construction speed is fast and the efficiency is high. And It can relieve pressure on resources, is conducive to environmental protection and reduces maintenance costs. The hot-in-place regenerative remixer is the main equipment used in this process. China Patent No. 200620090542.3 discloses a hot-i...

Problems solved by technology

In this conveying method, the material accumulates thickly during conveying, and it is difficult to heat

At the same time, the heated asphalt mixture is directly in contact with the steel base plate at room temperature. Due to the lack of insulation measures and the good heat conduction effect of the steel parts, the temperature of the asphalt mixture is greatly reduced, which affects the subsequent mixing process. This is the current thermal regeneration process. Two main reasons for the unsatisfactory heating effect of the mixer

Furthermore, in order to meet the temperature requirements of the stirring link, the temperature of the heating link has to be increased, resulting in high energy consumption of the equipment and serious thermal deformation of itself, which seriously affects the performance of the equipment and the quality of recycled materials
