Architectural sandstone screening device

Abstract

The invention relates to the technical field of screening machines, in particular to an architectural sandstone screening device which comprises a work chamber. A feeding device is arranged in the middle of the upper end of the work chamber; slide rails and screening devices are symmetrically arranged between the middles of a first clapboard and a second clapboard; U-shaped frames are symmetrically arranged on the front side and the rear side of outer walls of the screening devices; vertical slots matched with the screening devices are symmetrically formed in the first clapboard and the secondclapboard; a collecting frame is arranged on the right side of the lower part of the vertical slot located on the second clapboard; a power device is rotatably connected to one sides, far away from the screening devices, of rotary rods through pin shafts; and a discharge hole is formed in the middle of the lower end of the work chamber. The architectural sandstone screening device provided by theinvention is reasonable in structure design, convenient to use, and capable of improving the sandstone screening efficiency, carefully classifying sandstone, and absorbing powder dust produced duringsandstone screening at the same time, and has high functionality and practicability.

Description

technical field [0001] The invention relates to the technical field of screening machinery, in particular to a construction sand 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 screen the sand and gravel fi...

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
