Abstract

The invention provides a low-dust production system of common dry-mixed mortar. The low-dust production system comprises a sand conveyor belt, a drying roller and a dried material conveyor belt whichcommunicate with one another in sequence; an impurity conveying device is arranged under the dried material conveyor belt, and a discharging outlet of the impurity conveying device communicates with arecovery unit; the dried material conveyor belt and a discharging outlet of an ingredient feeder communicate with the interior of a stirring device which comprises an outer stirring tube and an innerstirrer; a feeding inlet and a discharging outlet are formed in the tube top/bottom of the outer stirring tube correspondingly; a tube side part comprises an upper concave arc way, a middle convex arc way, a middle concave arc way and a lower convex arc way which are connected in sequence; the protrusion part on the middle convex arc way is of a vertical structure, and left and right ingredient spray heads which are symmetrical in the left-right direction are embedded into the protrusion part; and a stirring unit in the inner stirrer comprises a stirring shaft, a stirring disc net and a bottom stirring disc. According to the low-dust production system, the dispersive capacity is high, the mixing uniformity is high, the recovery capacity is high, and the quality of products is high.

Description

technical field [0001] The invention relates to a dry-mixed mortar manufacturing equipment, which belongs to the field of building material production, in particular to a low-dust production system for common dry-mixed mortar. Background technique [0002] The construction site needs to use a lot of mortar. If the mortar is directly configured on the construction site, it will not only be labor-intensive, time-consuming, and labor-intensive, but also generate a lot of dust and noise, which is easy to pollute the environment. Therefore, dry-mixed mortar is mostly used in the prior art. [0003] Dry-mixed mortar is usually called hydraulic cement mixed mortar, also known as mortar dry powder, dry mix, dry mixed powder, etc., which refers to aggregate (such as yellow sand) and inorganic cementitious materials (such as cement) that have been dried and screened , fly ash) and additives (such as polymers) etc. in a certain proportion of physical mixing of a granular or powdery sub...
