Asphalt cement mortar stirring mainframe

Abstract

The invention relates to an asphalt cement mortar stirring main machine comprising a stirred tank body the bottom of which is provided with a discharge gate mechanism, a power device and a stirring device. The stirring device comprises two parallel stirring shafts arranged in a stirring tank horizontally. The asphalt cement mortar stirring main machine is characterized in that: a plurality of spiral stirring arms are fixedly connected with the two stirring shafts; stirring blades with via at the two sides of the middle part are respectively arranged at the ends of the stirring arms; the stirring blades on each stirring shaft are roughly arranged in a variable angel and spirally in the space; the stirring blades on the two stirring shafts axially arranged along the opposite spiral direction and the two spirals are intersected; the power device comprises a driving motor with the speed adjustable, which synchronously drives two stirring shafts through a transmission device. In the stirring device, a dual horizontal form is employed which is characterized in that the stirring arms and the stirring blades, an asymmetric spiral distribution is employed so as to avoid secondary breakup of mixed materials and precipitation and fossilization of large particles in the stirring as well as meet the quality requirement that the asphalt cement mortar perfuses a grout layer of a high-iron track plate without slag.

Description

technical field [0001] The invention relates to the field of construction mixing machinery, in particular to a mixing main engine used for mixing and producing asphalt cement mortar for high-speed railways. Background technique [0002] The construction of the slag-free track slab high-speed passenger dedicated line involves a problem of the grouting layer of the slag-free track slab: when the slag-free track slab is fine-tuned, the support layer of hydraulic material and the gap between the support slab and the bottom of the slag-free track slab must be For grouting in the gaps, the high-performance asphalt cement mortar cushion can provide appropriate rigidity and elasticity for the track. In order to ensure the bearing capacity of the track slab. This grouting joint is about 20 to 50mm. [0003] In order to obtain a full grouting layer, asphalt cement (CA) mortar is selected as the grouting material. This asphalt cement mortar must exhibit the following characteristics:...

AI Technical Summary

Problems solved by technology

Therefore, it is necessary to develop a mobile asphalt cement mortar mixer truck, which can carry the necessary materials, mix and pour directly on site to ensure the performance and construction quality of the mortar; and the existing mixing equipment can no longer meet the above technical requirements , so the core component suitable for high-speed railway asphalt cement mortar mobile mixing plant: asphalt cement mortar mixing host
