Embodiment Construction

[0017] In order to make the technical solution of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings. Any solution obtained by equivalent replacement and conventional reasoning of the technical features of the technical solution of the present invention falls within the protection scope of the present invention.

[0018] As shown in the figure, a buffer tank for the separation and recovery of old asphalt mixture includes a shell 1. The upper part of the shell is a cylindrical structure, and the lower part of the shell is a frustum-shaped structure with a large upper part and a smaller lower part. The feed pipe 3 and the discharge pipe 4 are arranged on the lower part of the shell; the first baffles 5 and the second baffles 6 are alternately arranged on the upper part of the shell from top to bottom.

[0019] Further, the first baffle is arranged obliquely from upper left to lower right.

Abstract

The invention provides a buffer tank for separation and recovery of an old asphalt mixed material. The buffer tank comprises a shell, the upper portion of the shell is of a cylinder structure, and thelower portion of the shell is of a big-end-up circular truncated cone structure. A feeding pipe is arranged on the upper portion of the shell, and a discharging pipe is arranged on the lower portionof the shell. The upper portion of the shell is provided with a first baffle blade and a second baffle blade which are arranged alternately from top to bottom, thus condensation and adhesion of the mixed material can be effectively prevented, and subsequent processing is facilitated.

Description

technical field [0001] The invention relates to a buffer tank, in particular to a buffer tank used for separation and recovery of old asphalt mixture. Background technique [0002] The old asphalt mixture for roads is mainly graded asphalt pavement due to rutting, cracking, aging and other diseases, and has been milled after maintenance and repair. The overall road performance of the road asphalt mixture can no longer meet the standard; the old asphalt mixture contains 3% to 4% asphalt and 97% to 96% aggregate; the road asphalt mixture is mainly mixed with standard 70# , 90# asphalt is wrapped on the outer surface of gravel and mineral powder, the asphalt is completely in a state of flow, and the binding force between asphalt oil and gravel molecules is very small. Old asphalt and aggregates can be recovered and recycled after separation. [0003] During the separation and recovery of old asphalt mixture, a buffer tank is needed to temporarily store the treated mixture. Th...
