High-efficiency graded screening and cleaning device for construction sand and gravel

Abstract

The invention discloses a high-efficiency graded screening and cleaning device for construction sand and gravel. The high-efficiency graded screening and cleaning device for construction sand and gravel comprises a feed pipe, a grid, a liquid level meter, a tank, a water inlet pipe, a flow meter, a sprayer, a rotary shaft, a camera, a timer, an impeller, a screen plate, a vibrator, a coarse sand discharge pipe and a fine sand discharge pipe, wherein the feed pipe is arranged at the top end of the tank; the grid is arranged in the feed pipe obliquely; the lowest end of the grid is provided withan impurity discharge pipe; the tank is provided with the liquid level meter and communicates with the water inlet pipe; the outlet end of the water inlet pipe is provided with the sprayer; the flowmeter is installed on the water inlet pipe; the camera is arranged on the inner wall of the top end of the tank; the rotary shaft is arranged in the tank and provided with the impeller; the screen plate is obliquely arranged in the tank; the vibrator is arranged on the lower surface of the screen plate; and the screen plate comprises a first screen plate body and a second screen plate body. The high-efficiency graded screening and cleaning device for construction sand and gravel is used for screening sand and gravel, improves the working efficiency, saves time and labor, and is simple in structure, convenient to use and beneficial to popularization.

Description

technical field [0001] The invention relates to a construction device, in particular to a high-efficiency classification, screening and cleaning device for construction sand and gravel. 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 hard and chemically stable in the surface environment. For sandstone, its weathering resistance is generally strong, especially the silicified quartz sandstone, whose hardness exceeds that of granite. Sand and gravel are the basic materials in national economic construction...

AI Technical Summary

Problems solved by technology

It has different effects on sand and gravel of different sizes. The existing sand and gravel screening work is inefficient and difficult to meet the needs of increasingly prosperous production and life.
