Description

Technical Field

[0001] The utility model relates to a screening device, in particular to a screening device for dry-mixed mortar used in construction engineering, belonging to the technical field of mortar screening. Background Art

[0002] Mortar is the bonding material used for bricklaying in construction. It is made of a certain proportion of sand and binder (cement, lime paste, clay, etc.) and water. It is also called mortar or mortar. Common mortars include cement mortar, mixed mortar (or cement lime mortar), lime mortar and clay mortar. They are widely used in construction, decoration and other fields. During the mortar production process, it needs to be transported between various processing areas through a conveying device. However, due to its own characteristics, the mortar has poor fluidity in the hopper, especially due to the restriction of the baffle. When it is transported to the conveyor belt, it becomes lumps, which affects transportation. Dry-mixed mortar is usually called hydraulic cement mixed mortar, which refers to a granular or powdered mortar made by physically mixing dried and screened aggregates, additives, and inorganic cementitious materials in a certain proportion. During the production of dry-mixed mortar, it is usually necessary to use a vibrating screening device for dry-mixed mortar to screen out some large materials inside.

[0003] A Chinese patent publication (publication number: CN 212349342 U) discloses a screening device, which includes a fixed cover.
