Description

Technical Field

The utility model relates to a store preventing material storage device that educes that bulk cargo was used, the utility model discloses still relate to a dry-mixed mortar mixing plant and mechanism sand production line including above-mentioned preventing material storage device that educes.

Background

In the field of material storage, bulk materials are usually stored in cylindrical bins, for example, in a dry-mixed mortar mixing plant, there is a finished product storage bin for storing finished dry-mixed mortar, and in a machine-made sand production line, there is a dry sand bin for dry sand. However, since bulk materials such as finished dry-mixed mortar and dry sand are usually formed by mixing a plurality of materials with different particle sizes, in the process of filling the bulk materials into the silo through the feed inlet positioned at the top of the silo, the slope accumulation is formed because the traditional feeding mode is single-point blanking, and due to the existence of height drop, the phenomenon that large-particle-size materials are arranged around and fine-particle-size materials are arranged in the middle can be formed, namely, the segregation problem occurs, which affects the quality of the final finished product, and the construction quality is reduced. There is therefore a need to deal with the problem of segregation of materials during the filling of bulk materials.

The existing segregation-proof principle is to reduce the segregation of the finished bulk materials by reducing the height difference of the bulk materials which are subjected to free-falling motion in the conveying process or adopting an inclined chute conveying mode to avoid the bulk materials from free-falling motion. However, although the mode of reducing the height difference can better ensure the smooth conveying of the bulk materials from top to bottom, the free falling motion of the bulk materials can be caused due to the height difference, so that the bulk materials are inevitably separated to a certain extent; although the inclined chute mode can better avoid the segregation of the bulk materials due to the free falling motion, the silo with the segregation-preventing structure is not suitable to be too high due to the arrangement of the inclined chute, the height of the straight cylinder part of the common silo is not suitable to exceed 5m, otherwise, the segregation-preventing effect is not ideal due to the low inclination.

Chinese patent application No. CN201310542236.3 discloses an anti-segregation structure in which a speed reducer drives a hopper to rotate at a low speed, and dry-mixed mortar in the hopper uniformly falls into a finished product bin through a chute. However, it still has the following disadvantages: 1) the driving mechanism is a speed reducer and a rotating shaft, and the connecting part of the conical hopper and the rotating shaft is impacted and abraded by falling dry sand, so that faults are easily caused; 2) if the rotating shaft is controlled improperly at a low speed, the dry-mixed mortar is subjected to circumferential tangential centrifugal force, and the segregation phenomenon is aggravated.
