Facing sand screening equipment for water permeable bricks

Abstract

The invention belongs to the technical field of facing sand screening equipment, and particularly relates to facing sand screening equipment for water permeable bricks. The facing sand screening equipment comprises a rack, wherein a set of screening cylinders are sequentially arranged at the upper part of the rack from left to right; the diameters of the screening cylinders are increased in sequence, and the connecting parts of every two adjacent screening cylinders are nested with each other and are rotationally connected; a pair of rolling shafts are arranged at the bottoms of the screeningcylinders, and the rolling shafts are used for supporting the screening cylinders to rotate; one end of each of the screening cylinders is fixedly connected with an outer gear ring, and a motor is fixedly connected to the position, corresponding to the outer gear ring, of the rack through a support; a gear fixedly connected with an output shaft of the motor is meshed with the outer gear ring; a feeding hopper is fixedly connected to the position, close to the outer gear ring, of each screening cylinder through a support; and a pair of first clamping blocks are arranged on the periphery of thescreening cylinder with the smaller diameter at the connecting position of every two adjacent screening cylinders, and a second clamping block is arranged on the inner circumference of the screening cylinder with the larger diameter. According to the facing sand screening equipment, when the motor rotates forwards and reversely, the first clamping blocks and the second clamping block are matched to increase the vibration of the screening cylinders, so that the blockage of screening holes is reduced.

Description

technical field [0001] The invention belongs to the technical field of surface sand screening equipment, in particular to a surface sand screening equipment for permeable bricks. Background technique [0002] For a long time, due to the random mining of natural medium and coarse sand, the water environment has been seriously damaged, and it has caused certain hidden dangers to shipping safety. This situation has attracted the attention of the relevant administrative departments, and the ban on mining has been continuously increased. Many natural rivers and lakes have implemented permanent bans on mining. The market supply of natural medium-coarse sand is becoming increasingly tight. Concrete manufacturers are looking for alternative materials for natural medium-coarse sand. Various alternative fine aggregates such as machine-made sand, washed stone chips, tailings sand, and surface sand are on the scene. Due to the great difference in the performance of these alternative fi...

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology, the existing screening machine is only suitable for medium sand and coarse sand with large particle diameters. The soil blocks in the surface sand are easy to block the screen cylinder, which seriously affects the screening efficiency of the surface sand, and needs to be shut down for manual operation. Cleaning, increasing labor intensity, and reducing the screening efficiency of surface sand, a kind of surface sand screening equipment for permeable bricks proposed by the present invention
