Gravel flushing device for constructional engineering

Abstract

The invention discloses a gravel flushing device for constructional engineering. The gravel flushing device comprises a sand inlet pipe, a screening box, a water spray tank, a water filter film plate,a table plate, a vibration screening basket, a rotating barrel and a water outlet pipe. The sand inlet pipe is arranged at the top end of the screening box. A grid is obliquely arranged in the sand inlet pipe. One side of a feeding plate is hinged to the inner wall of the top end of the screening box. The table plate is arranged in the screening box. Sand sliding grooves are formed in the side wall of the table plate. The water spray tank is mounted at the top end of the screening box. The bottom end of the water spray tank is connected with a spray head through a water passing pipe. The spray head is arranged in the top end of the screening box. Fixed blocks are arranged on the inner wall of the screening box. The upper surface of each fixed block is fixedly connected with one end of a spring, and the other ends of the springs are in contact connection with the bottom face of the vibration screening basket. The rotating barrel is arranged above the vibration screening basket. A semicircular gear is connected with an output shaft of a rotary motor. The water filter film plate is obliquely arranged in the screening box. According to the gravel flushing device, gravel flushing is facilitated, resources are saved, waste is avoided, the structure is simple, use is convenient, and popularization is facilitated.

Description

Technical field [0001] The invention relates to a construction engineering field, in particular to a construction engineering sand and gravel washing device. Background technique [0002] Because of its good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials and concrete raw materials and are widely used in housing, roads, highways, railways, engineering and other fields. With the requirements of infrastructure construction technology and the development of high technology, there are higher requirements for the quantity and quality of sand and gravel. Sand and gravel are loose materials, but their particles are generally harder and chemically stable under the surface environment. For sandstone, its resistance to weathering is generally strong, especially for silicified quartz sandstone, whose hardness exceeds that of granite. Sand and gravel is the basic material in the national economic construction, mainly used for basic...

AI Technical Summary

Problems solved by technology

The surface of sand and gravel generally contains a large amount of fine soil and other impurities, which will affect the quality of concrete and affect the construction effect in severe cases.
