Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for producing recycled concrete. Background Art
[0002] Recycled concrete refers to new concrete made by crushing, cleaning, and grading discarded concrete blocks, mixing them with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregate), and then adding cement, water, etc. During the production process of recycled concrete, a stirring device is often required to stir the recycled aggregate. There are at least the following disadvantages in the use of existing stirring devices: 1. During the use of existing stirring devices, most of the stirring blades are ordinary stirring blades. When dealing with harder aggregates, ordinary stirring blades are prone to deformation and damage after long-term work, and thus need to be replaced frequently, increasing the economic burden; 2. During the use of existing stirring devices, after aggregates accumulate at the discharge port, it is easy to become blocked, and manual cleaning of aggregates is required for normal discharge, which increases the burden on staff. Therefore, we have introduced a stirring device for recycled concrete production. Utility Model Content
