Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aggregate mixing equipment, and more specifically, to a lightweight aggregate mixing equipment. Background Technology
[0002] Lightweight aggregate concrete, as an excellent green building material, is widely used in bridge and pavement paving, prefabricated housing, and PC components due to its advantages such as being lightweight, high-strength, durable, and reducing alkali-aggregate reaction. The mixing of lightweight aggregates is usually carried out in corresponding mixing equipment. There are many types of mixing equipment on the market. When using most mixing equipment, the raw materials are put into the corresponding cylinder, and then the motor drives the corresponding mixing shaft and mixing blades to rotate to achieve the mixing operation.
[0003] However, in use, the top of such mixing equipment is generally directly connected to the outside, or it has a feed hopper at the top, but the top of the feed hopper is also directly connected to the outside. Although this facilitates the addition of raw materials, the direct exposure without corresponding covering components easily leads to a large amount of dust being blown out during the mixing process, polluting the surrounding air and causing inconvenience to users. In view of this, we propose a lightweight aggregate mixing equipment. Utility Model Content
