The CA mortar mixer
Technical field
The utility model relates to a kind of CA mortar mixer, and this equipment can be used for the perfusion of CA mortar in the railway slab track and stirs.
Background technology
The CA mortar is the abbreviation of the cement asphalt mortar elastic insert (cementasphaltmotar) of slab track, make through fusion at normal temperatures by materials such as special asphalt emulsion, cement, admixture, fine aggregate, water, aluminium powders, be the key components of slab track.The CA mortar is to utilize cement suction aquation to quicken the emulsified asphalt breakdown of emulsion, and being interweaved by cement-hydrate and pitch wraps sand and form a kind of cubic network, and its performance quality directly has influence on durability and the maintenance workload that plate-type ballastless track uses.
Because the perfusion of track plate CA mortar is the key technology of plate-type ballastless track construction, therefore fluidity and the inspection of air content density to mortar all has strict requirement in CA screed filling process.Track plate CA mortar mixer in using at present is mainly the forced action type concrete mixer, stir too strong, can not satisfy the technological requirement of CA mortar aspect mixing, aerating, breakdown of emulsion well, thereby cause production efficiency not high, problems such as construction cost increase.Also do not find at present desirable CA mortar blending device design data report.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of CA mortar mixer, and this equipment design science, reasonable uses this equipment can satisfy the stirring requirement of CA mortar aspect mixing, aerating, breakdown of emulsion well.
The technical scheme that the utility model adopted is: this CA mortar mixer is a vertical structure, comprises mixing drum and support.Adjustable frequency motor and decelerator are equipped with in the center of stirring cover at the mixing drum top, stir the cover periphery and be provided with spout and screen cloth, be provided with many group guide plates and hit plate at mixing drum inwall and bottom radial symmetric, the bottom of mixing drum is taper, and the discharging opening of conical lower portion is connected with the blowing elbow by dispensing valve.Central authorities at mixing drum are shaft, and the upper end of shaft is connected with decelerator, and agitator disk is equipped with in the bottom.Agitator disk is a disk, and symmetry is welded with several paddles on it.The bottom of agitator disk is identical with the conical bottom angle of mixing drum, and leaves the mortar flow channel between two ends.
The beneficial effects of the utility model are: because the improvement of agitator stirring structure has increased agitating function, improved stirring efficiency owing to adopted the variable-frequency stepless speed-regulating system, can realize in the different phase whipping process to the requirement of speed of agitator.Can also be determined under the different rotating speeds different mixings time to the effect of CA mortar, in view of the above design and selection process in the stages such as mixing, aerating, breakdowns of emulsion.
