Description

Sand and stone straight line screen

Technical Field

The utility model relates to the technical field of sand screening, in particular to a sand linear screen.

Background

The sand aggregate is a collective name of sand, gravel (gravel) stone, broken stone, block stone, material stone and other materials in hydraulic engineering. The sand aggregate is a main building material of structures such as concrete, piled masonry and the like in hydraulic engineering; aggregates with a particle size of more than 5mm are called coarse aggregates, namely stones which are commonly called by us, and aggregates with a particle size of less than 5mm are called fine aggregates, namely sand; the sand stone material is a main building material of structures such as concrete, piled masonry and the like in hydraulic engineering; screening is a process of dividing mixed waste of particles with different particle diameters into two groups or more than two groups of particle groups by utilizing one or more than one screening surface; screening is carried out by wet separation and dry separation, solid waste is screened by dry separation, and screening can be carried out simultaneously by a plurality of screening surfaces; the screening process can be divided into two processes of material layering and fine particle screening, wherein fine particle screening is the purpose of separation.

When the sand and stone linear screen screens sand and stone, sand and stone with different sizes need to be mixed and poured on the surface of the screening net, and then the vibrating motor drives the linear screen to vibrate, when the sand and stone is screened, as the two sides of the linear screen are mutually parallel to the screen surface, sand and stone easily fall onto the surface of the screen of the next stage from the two sides of the linear screen under the condition of vibration when the sand and stone are screened up and down due to the fact that the two sides of the linear screen are mutually parallel to the screen surface, so that the sand and stone screening is disordered, and the sand and stone screening effect is poor;

when the grit is screening through the straight line sieve, in order to avoid the grit to produce a large amount of dust in the screening process, usually personnel can carry out the dust fall with grit shower water when carrying out the grit screening, and tiny grit is inside the discharge sieve separator of bottom, because the grit is soaked by water in the dust fall in-process, consequently tiny grit pile up very easily at sieve separator bottom inner wall when passing the sieve separator bottom to cause the unable discharge sieve separator of sieve separator bottom inside, lead to the result of the use of sieve separator relatively poor.
