Building waste mud sand washing production line

Abstract

The invention relates to a building waste mud sand washing production line which comprises a sand washing tank, which is provided with at least one washing tank, and washing wheels, the axes of which are horizontally arranged in the washing tank. Each washing wheel comprises a ring body which is rotationally connected to the sand washing tank; a plurality of bailing hoppers which are located on the circumferential surface of the ring body; sliding blocks which are fixed to the bailing hoppers, penetrate through the ring body in the radial direction of the ring body and are connected to the ring body in a sliding mode; limiting plates which are fixed to the sides, capable of extending to the inner circumferential surface of the ring body, of the sliding blocks and limit the sliding blocks from being separated from the ring body when the sliding blocks slide from the interior of the ring body to the exterior of the ring body; and an elastic ring which is arranged in the ring body and is coaxial with the ring body, one end of the elastic ring being fixedly connected to the inner circumferential surface of the ring body, the other end thereof being a free end, and the elastic ring being capable of abutting against and pushing the sliding blocks to move in the direction away from the axis of the ring body. The building waste mud sand washing production line has the advantages that sand remaining on the bottom face of the washing tank is reduced, and the effect of fully washing sand is achieved.

Description

technical field [0001] The present application relates to the technical field of construction waste recycling, in particular to a construction waste mud sand washing production line. Background technique [0002] In the field of construction, with the process of building construction, a large amount of construction waste will inevitably be produced. In order to improve the utilization rate of resources, this part of construction waste is generally recycled and reused. The recycling process of construction waste is generally first. The construction waste is crushed, and impurities such as iron filings and sawdust are picked out, and then the remaining sand is cleaned to obtain clean washed sand. In the process of cleaning the sand, it is necessary to use the construction waste mud sand washing production line to remove the impurities covering the surface of the sand and gravel. [0003] At present, the washing sand production line generally only includes a washing tank and a...

Problems solved by technology

[0004] However, the impeller of the existing washing sand production line is often unable to fish the sand on the bottom of the washing tank, resulting in a large amount of sand remaining on the bottom of the washing tank, and it is impossible to achieve sufficient sand washing
