Working method of building gravel screening device

Abstract

The invention relates to the technical field of screening machines, in particular to a working method of a building gravel screening device. The working method of the building gravel screening devicecomprises a work tank; a feeding device is arranged in the middle of the upper end of the work tank; a slide rail and the screening device are symmetrically arranged between the middles of a first partition plate and a second partition plate; U-type frames are symmetrically arranged on the front and rear sides of the outer wall of the screening device; vertical grooves matched with the screening device are symmetrically formed in the first partition plate and the second partition plate; a collection frame is arranged on the right side of the lower portion of the vertical groove in the second partition plate; the side, away from the screening device, of a rotary rod is rotationally connected with a power device through a pin shaft; and a discharging outlet is formed in the middle of the lower end of the work tank. The structural design is reasonable, use is convenient and rapid, gravels can be graded more finely while the gravel screening efficiency is improved, dust generating by screening the gravels can also be adsorbed, and high functionality and practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of screening machinery, in particular to a working method of a construction sand and stone screening device. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. Sand and gravel are often used in building construction to produce concrete. Sand and gravel refer to the loose mixture of sand and gravel. Construction sites usually purchase sand and gravel in large quantities, but the quality of the current sand and gravel is uneven. There are some large stones, branches and other sundries in it. Existence seriously affects the quality of concrete and may cause safety hazards to the overall structure of the house. Therefore, it is necessary to...

Problems solved by technology

Sand and gravel refer to the loose mixture of sand and gravel. Construction sites usually purchase sand and gravel in large quantities, but the quality of the current sand and gravel is uneven. There are some large stones, branches and other sundries in it. Existence seriously affects the quality of concrete and may cause safety hazards to the overall structure of the house, so it is necessary to screen the sand and gravel first

[0003] The screening devices currently used in construction sites are usually single-stage screening, which only screen out the larger stones and other sundries in the sand and gravel, and cannot perform more detailed classification, which cannot meet the actual conditions of current construction. Requirements, and the screening efficiency of this screening device is low, and the screen is easy to block, which will affect the progress of the project

In addition, the existing screening device lacks a corresponding dust removal system, and a large amount of dust pollution will be generated during screening, which is not conducive to environmental protection
