Sand and stone washing type grading lifting vibration device

Technical Field

The utility model relates to the technical field of sand and stone separation, in particular to a sand and stone washing type grading lifting vibration device.

Background

Sand refers to a loose mixture of sand and broken stone, sand is often used in the building field, and according to different building requirements, the particle size requirements of sand in the building process are different, for example, coarse sand can be used in road construction, and fine sand is required in bridge construction and house construction.

With the development of the construction engineering industry, the machine-made sand is used as one of the main ingredients of the concrete, and the production and use scale is continuously enlarged. Because the machine-made sand is made by crushing stones by a sand making machine, the sand grains prepared by preliminary crushing of the machine-made sand are different in size, and the sand is required to be classified and screened and crushed for multiple times. Meanwhile, stone powder can be generated in the two-stage crushing and three-stage crushing processes of sand and stone, and part of sand also carries sediment. Although the sand and stone can be cleaned after the secondary crushing and the tertiary crushing, the sand and stone still contain a small amount of stone powder and sediment in the transportation process, and if the stone powder is doped in the process of manufacturing the concrete, the quality of the concrete can be seriously affected. In addition, as the classifying screening process is mostly carried out by adopting a vibrating screen, the stone powder can fly up due to the vibration of the vibrating screen in the vibrating screening process.

Disclosure of Invention

The utility model aims to provide a sand water-washing type grading lifting vibration device which can reduce the stone powder content in sand and avoid dust flying in the separation process.

The basic scheme provided by the utility model is as follows: the sand and stone water washing type grading lifting vibration device comprises a vibration sieve and a flushing device, wherein a plurality of layers of screen meshes are sequentially arranged in the vibration sieve along the vertical direction, the pore diameters of the screen meshes of the plurality of layers of screen meshes are gradually decreased from top to bottom, and the flushing device for uniformly flushing the vibration sieve is arranged above the vibration sieve.

The principle of the utility model is as follows: the vibrating screen is used for vibrating and sorting sand and stone, so that sand and stone meeting the use requirement can be output in a grading manner. After the stone is crushed for the second time, the crushed sand particle sizes are different, and a part of sand particles are larger in particle size and cannot meet the use requirement, so that the stone needs to be crushed again.
