Abstract

The invention discloses an indoor mixer for an asphalt mixture. The indoor mixer comprises a rack, a raw material adding device, a mixture stirring device, an asphalt smoke collecting device and a comprehensive control panel, wherein the rack is used for providing a working platform for each accessory part of the mixer, the raw material adding device can store and add raw materials in a heat preservation manner, the mixture stirring device can perform synchronous reverse rotation stirring and automatic discharging of a stirring cylinder and a stirrer, the asphalt smoke absorption device can beused for absorbing harmful gases such as asphalt smoke generated in the production process of the mixture, and the comprehensive control panel is electrically connected with the raw material adding device and the mixture stirring device and is used for comprehensively controlling the raw material adding device and the mixture stirring device so that the whole process control from raw material adding, mixture stirring to finished product material pouring is realized. The indoor mixer is advantaged in that the indoor mixer for the asphalt mixture can effectively improve the mixing quality of the mixture and remarkably reduce emission of asphalt smoke in the production process of the mixture.

Description

technical field [0001] The invention belongs to the technical field of material stirring and mixing, and in particular relates to an indoor mixing device for asphalt mixture. Background technique [0002] With the increasing number of asphalt concrete pavements on domestic highways, asphalt mixture indoor mixers have been widely used in the field of construction and maintenance of asphalt concrete pavements. Among them, there are two outstanding problems in the common asphalt mixing indoor mixer. First, there is a structural defect in the vertical mixing pot used, that is, there is a certain vertical distance between the stirring paddle and the mixing pot. During the process, the stirring paddle does not stir the mixture at the bottom of the mixing pot in place, so that the mixture at the bottom of the mixing pot is unevenly stirred. This phenomenon is especially obvious when the fine aggregate is mostly at the bottom of the pot. Second, in the design of the indoor asphalt ...
