Abstract
Description
Technical Field
[0001] This utility model relates to the field of wet-mixed mortar preparation technology, specifically a precise metering device for wet-mixed mortar production. Background Technology
[0002] Wet-mixed mortar refers to a mortar mixture made by mixing cementitious materials, fine aggregates, admixtures, water, and other components determined according to their performance characteristics in a certain proportion at a mixing plant. After being metered and mixed, the mixture is transported to the point of use by a mixer truck, stored in a special container, and used within a specified time. The working principle of wet-mixed mortar is similar to that of ready-mixed concrete; however, ready-mixed concrete mixing plants can simultaneously produce wet-mixed mortar.
[0003] In the preparation of wet-mixed mortar, weighed materials (cement, mineral powder, fly ash) are transported via pipelines, while liquids (admixtures, water) are fed into a mixer for mixing. Existing patent application number CN202220300936.6 discloses a metering and feeding device for wet-mixed mortar production, where materials are directly fed into the mixer after weighing, accelerating material feeding and mixing and reducing the time and steps required for reusing the feeding device. However, during the batching and weighing process, multiple metering plates are needed to weigh different materials, increasing equipment costs and preventing the pre-mixing of the batched materials.
