Abstract

The invention discloses a sand screening facility capable of scraping sand on a belt and characterized by being adjustable in the separation distance between a scraping plate and the belt. The sand screening facility structurally comprises a sand scraping device, a supporting frame, a finished product sand conveying device, a discharging drum, a drum screen, a raw material feeding belt conveyor and a raw material storage hopper. The drum screen is arranged on one side of the supporting frame. Compared with the prior art, the sand screening facility has the beneficial effects that the sand which is kept on the belt can be timely scraped, the phenomenon of accumulation of the sand is effectively avoided, and therefore the sand conveying speed cannot be affected; the normal amount of sand canbe held in a screen drum, and therefore the electric energy is saved advantageously as the screening efficiency is improved, and then the screening cost is reduced; meanwhile, the phenomenon that dueto accumulation of the sand, the flowing sand slides to a rotating shaft can be avoided, the phenomenon that the rotating shaft gets stuck is avoided, the belt can normally supply materials, and theconstruction progress is not affected; and the gap between the sand scraping plate and the belt is adjustable, sand scraping operation is more facilitated, the sand scraping plate is convenient to replace and install, and sand discharging operation is also thorough.

Description

technical field

[0001] The invention relates to the technical field of building construction, in particular to a sand screening device capable of scraping sand on a belt and having an adjustable distance between the scraper and the belt. Background technique

[0002] Sand is the main material for concrete and mortar. Because sand has different thicknesses, different specifications of sand are required for different construction conditions. Therefore, it is necessary to screen the sand, which is often screened by a drum type sand screen machine. When screening, the raw materials pass through The feeding belt is put into the horizontal screen drum for screening. In the raw material transportation, due to the imperfect technology of the existing drum sand screen machine, the following defects need to be improved:

[0003] 1) During the construction of the construction site, the drum type sand screening machine and the sand are placed in the open air. Because the air contains wa...
