High-efficiency sand sieving device for municipal construction

Abstract

The invention discloses a high-efficiency sand sieving device for municipal construction. The high-efficiency sand sieving device for municipal construction comprises a sieving box. The top of the sieving box is provided with a top plate. A driving motor is arranged on the top plate. An output shaft of the driving motor is coaxially and fixedly provided with a driving belt pulley. A second smashing rotary roller is coaxially and fixedly provided with a fourth driven belt pulley and a third driven belt pulley. A first driving bet is wound around the third driven belt pulley and the driving beltpulley. The right end of a concentric-square-shaped frame is horizontally and fixedly provided with a right guide slide rod which is slidably connected with the right sidewall of the sieving box. Sand entering the sieving box through a feed hopper is scattered by a first smashing rotary roller and the second smashing rotary roller in the rotating process, so that caking sand blocks in the sand are broken up and scattered. Rotary blades rotate to promote scattering of the sand. Meanwhile, wind generated by rotating of the rotary blades promotes flowing of air in the sieving box to play a rolein drying the sand. The fluidity of the sand is improved, and the subsequent sieving effect is improved accordingly.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to a high-efficiency sand screening device for municipal construction. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings that are set up within the planning and construction scope of urban areas and towns (townships) and provide residents with paid or free public products and services based on government responsibilities and obligations. , structures, equipment, etc., all kinds of public infrastructure construction supporting urban life belong to the category of municipal engineering, such as common urban roads, bridges, subways, such as various pipelines closely related to life: rainwater, sewage, water supply, medium Water, electricity, telecommunications, heat, gas, etc., as well as the construction of squares, gardens, etc. [0003] In the process of...

AI Technical Summary

Problems solved by technology

[0003] In the process of municipal construction, sand, as one of the most important building materials, needs to be screened according to relevant construction specifications before use. The fine sand is used for municipal construction; the existing sand screening device does not have a good screening effect on sand, and the agglomerated sand clusters are relatively large in size, making it difficult to screen, and at the same time, it is easy to cause blockage of the screen mesh, which greatly reduces the screening efficiency
