Slender type double-shaft mixer with heating heat-preservation function

Abstract

The invention discloses a slender type double-shaft mixer with a heating heat-preservation function and belongs to the technical field of hot in-place recycling of asphalt pavements. The slender typedouble-shaft mixer comprises a mixing cylinder and two stirring shafts. The mixing cylinder is constituted by an outer cylinder body and an inner cylinder body, and the part between the outer cylinderbody and the inner cylinder body is filled with a heat-preservation material; an abrasion-resistant lining plate is mounted in the mixing cylinder in a sleeved mode, and the top of the mixing cylinder is covered with a heating plate; each stirring shaft is in a sectional type, and the sections of each stirring shaft are connected through connecting short shafts; mounting frames are arranged in the positions, on the upper portions of the connecting short shafts, of the mixing cylinder and provided with bearing seats in a hoisting mode; and the connecting short shafts are mounted in the bearingseats. The adopted structure is convenient to maintain, errors are small, and a new asphalt and used asphalt mixture is heated and mixed, so that a constructed asphalt pavement is higher in quality and better in effect.

Description

technical field [0001] The invention relates to a slender twin-shaft mixer, in particular to a slender twin-shaft mixer with a heating and heat preservation function, which is used for mixing asphalt mixture in in-situ thermal regeneration construction of asphalt pavement. The invention belongs to the technical field of asphalt pavement construction machinery and equipment. Background technique [0002] A mixer is a mechanical device used to mix a variety of different materials and form a mixture, which is widely used in various industrial production and engineering practices. As a key link in hot-in-place regeneration process of asphalt pavement, the mixing quality of asphalt mixture directly affects the quality of pavement. However, the temperature of the asphalt mixture mixed by the existing mixer is often low when it is bonded to the road surface and cannot meet the construction requirements, thereby reducing the quality of the road surface. Secondly, the wear-resistan...

Problems solved by technology

However, the temperature of the asphalt mixture mixed by the existing mixer is often low when it is bonded to the road surface and cannot meet the construction requirements, thereby reducing the quality of the road surface

Secondly, the wear-resistant liner of the existing agitator is assembled from a number of small wear-resistant plates. When the wear is serious and needs to be replaced, it usually needs to be disassembled piece by piece, which is relatively complicated.

Finally, the error compensation of the existing slender twin-shaft mixer is mostly the error caused by the manufacture of the product, but when the length of the slender twin-shaft mixer is long and the stirring shaft is a single long axis, when When the ambient temperature changes greatly, there is often no remedy for the error caused by the temperature difference change
