Drum-type sand screening device based on building construction

Abstract

The invention provides a drum-type sand screening device based on building construction, and relates to the field of building. The device comprises a rotary drum for screening sand, a fixed shaft, two side supporting plates, a lifting screening mechanism for screening the sand and a dispersing screening mechanism for further screening the sand, a bearing matched with the fixed shaft is arranged on the surface of the rotary drum, and the surface of the fixed shaft is fixedly connected with an inner ring of the bearing. According to the drum-type sand screening device for building construction, a special structure capable of dispersing and screening sand and comprehensively screening the sand is designed according to the problems that an existing sand screening device is high in energy and low in efficiency, and therefore the problems that according to a common screening device, it is difficult to break and remove cakes of the sand, and due to the influence of the flowability of the sand, a lot of sand cannot be in contact with a sieve to be sieved in the flowing process, idle work is often performed, and high energy consumption and low efficiency are caused are solved.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a drum-type sand screening device for building construction. Background technique [0002] In the process of construction, it is often necessary to sieve the sand. The commonly used method is to directly copy the sand to the sieve that is placed on a slant. During the flow of the sand, the sand will be sieved by the sieve, and there are also some mechanical equipment , when the drum-type sand screening device screens the sand, during the rotation of the drum, the sand is screened through the cylindrical sieve, which is significantly more efficient than manual work, but the sand inside the drum-type screening device is stacked Yes, the sand has fluidity. During the rotation of the drum, the sand will roll and flow above the sand, and only the sand at the bottom touches the screen to be sieved out. This makes the efficiency very low, and the sand is easy to get wet and agglomerat...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a drum-type sand screening device based on building construction, which solves the problem that it is difficult for the general screening device to break the agglomeration of sand, and is affected by the fluidity of the sand itself. Can not touch the sieve for sieving in the flow, often do useless work, resulting in the problem of high energy consumption and low efficiency
