Aggregate drying drum and drying method for dry-mixed mortar production line

Abstract

The invention relates to the technical field of stirring equipment, in particular to an aggregate drying drum and a drying method. The aggregate drying drum for a dry-mixed mortar production line comprises a rotating cylinder and a lifting blade arranged on the inner wall of the rotating cylinder, and further comprises an aggregate scattering device, wherein the aggregate scattering device comprises a support component and multiple bent blades; the multiple bent blades are uniformly distributed on the peripheral section of the rotating cylinder by the support component; and each bent blade performs holding and lifting actions along with the rotation of the cylinder, so that the peripheral section of the whole rotating cylinder is uniformly distributed with curtains. The aggregate drying drum enables aggregate moisture to be quickly reduced, quickens the temperature rise to prevent materials from being bonded on the drum, improves the use effect of subsequent lifting blades, radically solves the problem of bonding the materials on the drum, improves the curtain effect in the drum, improves the heat efficiency of the drum, and can reduce the heat source consumption.

Description

technical field [0001] The invention relates to the technical field of mixing equipment, in particular to an aggregate drying drum and a drying method that replaces the traditional lifting plate for single-sprinkling and forms multiple distributions. Background technique [0002] At present, the source of raw material sand for dry powder mortar is mainly river sand, which has a good grain shape and wide sources, and is widely used in mortar. Wet aggregates such as river sand need to be dried by drying drums before being put into the mixing device. For the above problems, the invention patent application with the authorized announcement number CN 202254751 U discloses a drying drum, which includes a cylinder, and is characterized in that the drying drum also includes a curved wall arranged on the inner wall of the cylinder. Lifting plates with the same bending direction and different bending angles. [0003] With the depletion of river sand resources and the serious damage t...

AI Technical Summary

Problems solved by technology

When using the traditional drying drum to deal with this kind of sand source, it often occurs at the front end of the drum, the wall of the drum and the blade of the lifting plate are seriously sticky, the blade lifting effect is poor, and the tail gas temperature is high, etc., although there are still some problems. The equipment has added special cleaning chains arranged on the cylinder wall and blades, which will alleviate the bonding problem to a certain extent, but the material strip will wear the cylinder wall after long-term operation, and the chain operation noise is large, so it is necessary to add a noise reduction device. , so the traditional aggregate drying equipment urgently needs to be improved
