A circulating sand screening device for construction engineering

Abstract

The invention discloses a circulating sand screening device for construction engineering, which comprises a stirring chamber, a screening chamber, a conveyor belt and a circulation mechanism; a motor is arranged at the upper end of the stirring chamber; a hinged plate is hinged on the inner side wall of the screening chamber, The inner side of the hinge plate is provided with a groove, the groove is provided with a first spring, and the left end of the first spring is fixedly connected with the sieve plate; the left end of the screening chamber is provided with a collection chamber, and the left end of the collection chamber is provided with a circulation mechanism. The invention is novel in design. The sieve plate moves up and down under the action of the eccentric wheel to screen the sand. When the sieve plate reaches the highest end, the impurities and part of the sand on the sieve plate enter the collection chamber through the through hole and enter the collection chamber. The sand enters the circulation mechanism through the filter screen, and then passes through the conveyor belt of the circulation mechanism into the mixing chamber, so that the impurities are effectively separated and stored, which is convenient for processing, and at the same time reduces the number of times of secondary sand screening, thereby improving the efficiency of sand screening.

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...

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
