Grading sand screening device for building construction

Abstract

The invention provides a kind of grading and sand screening equipment for building construction, which comprises a tank body; the tank body is set as a hollow cuboid with a square cross section, an upper cover is set at the top opening of the tank body, and a bottom opening is set at the bottom opening of the tank body. cover; the middle part of the tank body is divided into a drying chamber and a screening chamber by a partition; a drying device is provided in the drying chamber; a screening plate and a screening device are provided in the screening chamber; feeding device; the present invention adds the sand added by the feeding hopper into the tank body at a uniform speed through the feeding device, which is also beneficial to reduce the labor intensity of the workers; through the setting of the drying device, the three-layer rotating material guide plate is used to control the sand falling on the guide The sand in the material tray is turned over, and the hot air blown by the hot air blower is used to evenly distribute the hot air blown in by the three-layer rotating air distribution pipe, so as to facilitate the full drying of the sand; The sand is graded and screened to improve the screening quality.

Description

technical field [0001] The invention relates to construction equipment, in particular to a graded sand screening equipment for construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. In the process of building construction, sand with different particle sizes is needed, but the sand with different particle sizes is mixed together before use, and it is not easy to classify and utilize the sand. It is necessary to classify and screen the sand. The existing sand screening equipment, sand Accumulation is easy to occur inside the equipment, resulting in ...

AI Technical Summary

Problems solved by technology

In the process of building construction, sand with different particle sizes is needed, but the sand with different particle sizes is mixed together before use, and it is not easy to classify and utilize the sand. It is necessary to classify and screen the sand. The existing sand screening equipment, sand Accumulation is easy to occur inside the equipment, resulting in low screening efficiency. When the sand is transported to the construction site, the sand often contains a lot of water. If the water is not removed, the sand is easy to clump together, resulting in the failure of normal screening.
