Circulating type sand sieving device for building engineering

Abstract

The invention discloses a circulating type sand sieving device for building engineering. The circulating type sand sieving device for building engineering comprises a stirring cavity, a sieving cavity, a conveying belt and a circulating mechanism, wherein a motor is further arranged at the upper end of the stirring cavity; the inner side wall of the sieving cavity is hinged to a hinged plate; a groove is formed in the inner side of the hinged plate; a first spring is arranged in the groove; the left end of the first spring is fixedly connected with a sieve plate; a collecting cavity is formedin the left end of the sieving cavity; and a circulating mechanism is arranged at the left end of the collecting cavity. The circulating type sand sieving device for building engineering is novel in design, the arranged sieve plate vertically moves under the effect of an eccentric wheel to sieve sand, when the sieve plate reaches the highest end, impurities and part of sand on the sieve plate enter the collecting cavity through a through hole, the sand which enters the collecting cavity enters the circulating mechanism through a filter screen, and then enters the stirring cavity through a conveying belt of the circulating mechanism, therefore, the impurities are separately stored effectively, and are treated conveniently, meanwhile, the frequency of secondary sand sieving is reduced, and then the sand sieving efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a circulating sand screening device for construction engineering. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines and equipment. Among them, "housing construction" refers to projects that have roofs, beams, walls, foundations, and can form internal spaces to meet people's needs for production, living, learning, and public activities. [0003] Sand is an essential basic raw material in the field of construction. There are many impurities in the sand, such as gravel, garbage, etc., and the sand in the sand is also divided into different grades for different purposes. The required sand particle size grade different. Therefore, the sand needs to be screened before using it. The sand i...

AI Technical Summary

Problems solved by technology

The sand inside the sand pile is easy to agglomerate due to the high humidity or the presence of rainwater after rain. The current sand screening equipment generally does not have a stirring function, which reduces the sand screening efficiency, and the screen is fixed during the screening process. , the sand screening efficiency is low, which increases the labor intensity of workers and reduces work efficiency
