Efficient building sandstone screening and washing device

Abstract

The invention discloses an efficient building sandstone screening and washing device which comprises a feeding pipe, a grid, a liquidometer, a box body, a water inlet pipe, a flowmeter, a spray head, a rotary shaft, a camera, a timer, an impeller, a screen plate, a vibration exciter, a coarse sandstone discharging pipe and a fine sandstone discharging pipe; the feeding pipe is arranged at the top end of the box body and internally and obliquely provided with the grid; the lowermost end of the grid is provided with an impurity discharging pipe, the liquidometer is arranged on the box body, the box body communicates with the water inlet pipe, the outlet end of the water inlet pipe is provided with the spray head, and the flowmeter is installed on the water inlet pipe; the camera is arranged on the inner wall of the top end of the box body, the rotary shaft is arranged in the box body, and the impeller is installed on the rotary shaft; and the screen plate is obliquely arranged in the box body, the vibration exciter 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 efficient building sandstone screening and washing device is capable of screening sandstone, improving the working efficiency and saving time and labor, simple in structure and convenient to use and popularize.

Description

technical field

[0001] The invention relates to a construction device, in particular to a high-efficiency construction sand and gravel screening and cleaning 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 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, mainly used in fou...
