Efficient building sand sieving device capable of preventing meshes from being blocked

Abstract

The invention discloses an efficient building sand screening device capable of preventing meshes from being blocked. The device comprises a sand screening tank body and an arc-shaped track plate, the sand screening tank body is of a cylindrical structure, and the arc axis of the track plate and the rotation center line of the sand screening tank body are parallel and located on the same vertical plane; and a plurality of vertical supporting legs are welded to the bottom of the track plate, a collecting opening is formed at the bottom of the track plate, and a feeding opening and a waste opening are formed at the two ends of the sand screening tank body respectively. The efficient building sand screening device has the beneficial effects that in the rotating process of the sand screening tank body, sand always makes contact with two to three screens for screening, meanwhile, the axial size of the sand screening tank body is larger, a large amount of sand can be screened at the same time, and impurities such as gravel and garbage blocked by the screens in the sand can be conveyed through auger blades and finally leave the sand screening tank body from the waste opening; and the sand can be screened without shutdown, the screening efficiency and the sand screening thoroughness are greatly improved, and the efficient building sand screening device is particularly suitable for screening requirements of building construction.

Description

technical field [0001] The invention relates to the related technical field of construction equipment, in particular to a high-efficiency construction sand screening device for preventing blockage of mesh holes. Background technique [0002] With the rapid development of social economy, the construction industry is getting more and more people's attention. For a long time, people have played a very important role in the construction industry. Almost most of the operations are performed by people. Because construction personnel, no matter how good their skills are, errors may occur. In addition, the current building size The height and height are very large, and the requirements for building operation errors are even higher. [0003] Sand is an essential basic raw material in the field of construction. There are many kinds of impurities in the sand, and the sand particles in the sand are also divided into different grades. For different purposes, the required sand particle s...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that during the sand screening process of the sand screening device in the prior art, there are more and more gravels and garbage impurities on the screen, and at the same time, the meshes of the screen are easy to block sand particles, resulting in sand screening. The efficiency of the machine is reduced, and the sieving is not thorough enough, and the shutdown to clean the impurities on the sieve is not only time-consuming and laborious, but also affects the construction process, and a high-efficiency construction sand sieve with anti-clogging mesh is proposed. device
