A trommel sand screening device based on building construction

Abstract

The invention provides a drum type sand screening device based on building construction, comprising a rotary drum for screening sand, a fixed shaft, two side support plates, and a material extraction and screening mechanism for screening sand and a dispersing screening mechanism for further screening of sand, the surface of the rotating drum is provided with a bearing adapted to a fixed shaft, the surface of the fixed shaft is fixedly connected with the inner ring of the bearing, and relates to the field of construction. According to the problem of high energy and low efficiency in the existing sand screening device, the drum type sand screening device based on building construction is designed with a special structure that can disperse and screen sand and comprehensively screen sand. This effectively solves the problem that the general screening device is difficult to break the sand and agglomerates, and due to the influence of the fluidity of the sand itself, many sands cannot contact the screen for screening during the flow, often doing useless work, resulting in high energy consumption and low efficiency. The problem.

Description

Technical field [0001] The invention involves the field of construction technology, which is specifically a drum -type sand screening device based on construction construction. Background technique [0002] During the construction process, the sand is often sieved. The commonly used methods are manually copied the sand to the oblique sieve network. During the flow of the sand, the sand will be sieved. There are also some machinery and equipment. When the drum -type sand setting device is screened on the sand, during the rotation of the roller, the sand is sieved by a cylindrical sieve, which is obviously improved by the obvious efficiency. In, the sand is liquid. During the rolling process of the drum, the sand will roll above the sand, and only the bottom of the sand contact sieve can be screened. When screening, it is difficult to sieve sand. It is difficult to break the sand for the general screening device and affected by the liquidity of the sand itself. There is a problem w...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a drum-type sand screening device based on building construction, which solves the problem that it is difficult for the general screening device to break the agglomeration of sand, and is affected by the fluidity of the sand itself. Can not touch the sieve for sieving in the flow, often do useless work, resulting in the problem of high energy consumption and low efficiency
