Sand screening device for civil engineering

Abstract

The invention discloses a sand screening device for civil engineering, which comprises a base and a screening box. A feeding hopper is installed on the top of the screening box. The screening box includes two cavities, and the bottoms of the two cavities are inclined. Setting, the bottoms on both sides of the screening box are equipped with a discharge pipe communicating with the cavity, a baffle is installed on the discharge pipe, the bottom end of the feeding hopper extends to the middle of the screening box and A feeding pipe is installed, and the feeding pipe includes vertical pipes and horizontal pipes. The two cavities of the screening box are respectively provided with a first screening net box and a second screening net box. Both the first screening net box and the second screening net box are provided with a plurality of filter holes, and the diameter of the filter holes of the first screening net box is larger than the diameter of the filter holes of the second screening net box. Through the setting of various structures, this scheme can realize coarse screening and fine screening of sand at the same time, avoid secondary screening, the screening process is simple and efficient, improve work efficiency, save time and effort.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a sand screening device for civil engineering. Background technique [0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also refers to the object of engineering construction. That is, various engineering facilities built on the ground or underground, on land, directly or indirectly serving human life, production, military affairs, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, Airports, offshore platforms, water supply and drainage, and protection projects, etc. [0003] In civil engineering activities, it is necessary to use a sand screening device to screen and filter the san...

Problems solved by technology

[0003] In civil engineering activities, it is necessary to use a sand screening device to screen and filter the sand to remove foreign matter such as large-grained stones and stones, and then use the screened screen to make concrete mortar. The existing sand screening device has the following technical shortcomings : The function of the existing sand screening device is simple, and it is impossible to realize the coarse screening and fine screening of sand at the same time. If the sand after fine screening needs to be used, the screen needs to be replaced and then secondary screening will be performed, which will increase the complexity of the operation, waste time and effort, and reduce work. efficiency, and therefore need to be improved
