Sand sieving device for civil engineering

Abstract

The invention discloses a sand sieving device for civil engineering. The sand sieving device for civil engineering comprises a base and a sieving tank. A feed hopper is mounted at the bottom of the sieving tank. The sieving tank comprises two cavities. The bottoms of the two cavities are both inclined. The bottoms of the two sides of the sieving tank are both provided with discharge pipes communicating with the cavities. A baffle is mounted on each discharge pipe. The bottom end of the feed hopper extends to the middle of the sieving tank and is mounted at the discharge pipes. Each discharge pipe comprises a vertical pipe and a transverse pipe which are perpendicular to each other. A first sieving net cage and a second sieving net cage are arranged in the two cavities of the sieving tank correspondingly. The first sieving net cage and the second sieving net cage are each provided with a plurality of filter holes. The diameter of the filter holes of the first sieving net cage is greaterthan that of the filter holes of the second sieving net cage. Through arrangement of all the structures, the sand sieving device for civil engineering can achieve the rough sieving and fine sieving effects of sand without secondary sieving, and is simple and efficient in sieving process and capable of improving the working efficiency and saving time and labor.

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
