Circular building sand screening device

Abstract

The invention discloses a circular building sand screening device, and relates to the technical field of building machines. The circular building sand screening device comprises a supporting bottom plate, and a transverse packing auger driven by a motor I is horizontally and fixedly mounted on the supporting frame. A dispersing barrel communicating with the transverse packing auger through a discharging pipe is arranged below the transverse packing auger. A conveying belt mounted on a supporting table is arranged below a horizontal screen, and a longitudinal packing auger driven by a motor IIis fixedly mounted on the supporting table. A lifting inlet communicating with the dispersing barrel is formed in the lower right side wall of the longitudinal packing auger, and a circulating pipe ismounted between the upper right side wall of the longitudinal packing auger and the transverse packing auger in a communicating manner. According to the circular building sand screening device, sandcan be screened through the horizontal screen and an inclined screen and passes. By means of conveying of the transverse packing auger and the longitudinal packing auger, on one hand, the scattering function on the sand is improved, the mobility of the sand during screening is improved, and the screening effect is improved; and on the other hand, repeated and circular screening of the sand can beachieved, screening can be more sufficient and thorough, and the screening quality of the sand is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a circulating sand screening device 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. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] In the process of building construction, sand is one of the most commonly used building materials.

Problems solved by technology

[0003] In the process of building construction, sand is one of the most commonly used building materials. In the actual use process, it needs to be screened according to the needs of building construction to obtain sand with a particle size that meets the requirements. However, the screening of sand by the current sand screening device The effect is poor, and the sand is often screened only once, resulting in an insufficient and thorough sand screening process. For this reason, a circulating building sand screening device is now provided.
