Technical Field

The invention relates to the field of sand screening equipment, in particular to a sand screening machine with a sand guiding function and a using method.

Background

The assets built by building artificial buildings belong to the category of fixed assets and comprise houses and buildings. A house is an engineered building for people to live, work, study, produce, manage, entertain, store goods, and perform other social activities. The difference from buildings is structures, which refer to engineering buildings other than houses, such as fences, roads, dams, wells, tunnels, water towers, bridges, chimneys, and the like.

The building engineering is an engineering entity which performs various technical works and completions such as planning, surveying, designing, constructing, completing and the like for newly building, reconstructing or extending building buildings and affiliated structures and installation engineering of lines, pipelines and equipment matched with the engineering entity. Also refers to the construction of various houses and buildings, also known as the construction workload. The investment amount of the part can be realized only by the construction activities with the need of carrying out the work and the material movement.

Sand is an essential basic raw material in the construction work.

Common concrete sand in the construction industry generally requires medium sand. Most of sand in the desert is fine sand, which does not meet the requirements of the building industry. And the alkali content of sand in the desert exceeds the standard, and the sand contains a large amount of harmful substances due to long-term weathering. The houses made of sand from deserts are not suitable for long-term living of people and can harm the health of people. Sea sand has strong corrosivity, and cement stirred by the sea sand does not need five or six years, so that reinforcing steel bars can be corroded, and huge potential safety hazards exist.

Therefore, the river sand is the most ideal sand in the building, has smooth particles and certain smoothness on the surface, and is very suitable for preparing concrete. However, because the river sand is relatively rare, the usage amount of the river sand in the building industry is increased year by year, and the price of the river sand is also high. This also greatly increases the cost of construction, so that it is now common to replace river sand with purified sea sand (i.e. desalinated sand) for building construction.

River sand is naturally formed, has different particle sizes, and needs to be screened before use, so that the sand quality is ensured; in most construction sites, a manual sand screening mode is adopted, the labor intensity of workers is high, the sand screening efficiency is low, and the sand screening effect is poor; some sand screening devices have also been developed in succession, but these devices lack a pre-treatment for the sand to be crushed and the sand falls on the screen in a relatively concentrated position, with the screen being provided in a larger area, resulting in a smaller area for the screen to actually function. And large-area screen cloth still leads to the below to connect husky area also great, connects the material effect poor, needs the reasonable in design lead husky structure to conveniently concentrate on one and collect.

The inventor tries to reduce the screen area, but the method only reduces the base number and easily causes the condition of excessive screen load, does not actually improve the screening efficiency of the screen, and still needs to use a screen with a large area and improve the effective use area of the screen.

Therefore, the inventor designs the sand screening machine with the sand guiding function and the using method thereof, and solves the problems.
