Sand screening device used for municipal construction

Abstract

A sand screening device used for municipal construction comprises a screening box. A sand inlet pipe is installed on the top of the screening box. A turning wheel is located at the position of a lower pipe opening of the sand inlet pipe. Multiple vanes are evenly arranged in the circumferential direction of the turning wheel. Each vane extends in the axial direction of the turning wheel. Multiple blades are arranged in the axial direction of the surface of the turning wheel at equal intervals. A first screening plate and a second screening plate both penetrate the screening box rightwards and extend to the outer portion of the screening box. A limiting spring is longitudinally connected between the first screening plate and a first fixed plate. A limiting spring is longitudinally connected between the second screening plate and a second fixed plate. A servo motor is fixedly installed on a supporting plate. An auger is arranged on the lower portion in the screening box. A gas inlet pipe extends to the interior of the screening box leftwards. A spray head is installed at the end, away from a gas pump, of the gas inlet pipe. The sand screening device is ingenious in structure and reasonable in design, the turning wheel drives the first screening plate and the second screening plate to vibrate up and down under the elastic force effect of the limiting springs, the speed at which sand penetrates screen meshes in the first screening plate and the second screening plate is increased, and the screening speed of the sand is increased.

Description

technical field [0001] The invention relates to the technical field of municipal engineering construction, in particular to a 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, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity, telecommunications, Heat, gas, etc., as well as the construction of squares, gardens, etc., all belong to the category ...

AI Technical Summary

Problems solved by technology

At present, sand screening on construction sites is generally done by construction workers, which has a large workload and low work efficiency, making it difficult to achieve high-efficiency construction. Therefore, it is urgent to provide a sand screening device for municipal construction to improve Screening effect of sand to ensure construction quality requirements
