Rotary sand screening machine

Abstract

The invention relates to a rotary sand screening machine comprising a sand screening drum having two open ends, and supporting columns, wherein the supporting columns are arranged on bilateral sides of the sand screen drum; two ends of the sand screening drum are connected with end caps having gears; a central spindle is arranged inside the sand screening drum; two ends of the central spindle extend outside the end caps and are movably connected with the supporting columns; the central spindle is provided with a plurality of blades; a rotating shaft is arranged above the sand screening drum; and the rotating shaft is arranged on the supporting columns; the rotating shaft is movably connected with the supporting columns; a drive gear is sleeved on the rotating shaft; the drive gear is arranged above the end caps; one end of the rotating shaft is connected with an electric motor; the inner surface of the sand screening drum is provided with a gravity sensor; the supporting columns are provided with a controller, an alarm device and a storage battery; the gravity sensor and the alarm device are respectively connected with the controller; and the electric motor, the gravity sensor, the controller and the alarm device are all respectively connected with the storage battery. The problems that the sand screening efficiency is low, the sand agglomeration is hard to be crushed by screening, and the screening mesh is easily broken during the screening are solved by the rotary sand screening machine.

Description

technical field [0001] The invention relates to a drum sand screening machine, which belongs to the technical field of construction equipment. Background technique [0002] The sieve is a tool used by people to fix and separate large particles and small particles. According to the use of the sieve, it can be divided into construction sieves, domestic sieves and agricultural sieves. [0003] Sand is often used on building materials construction sites. Since the particle size of the sand is uneven when the sand is bought, and the particle size varies greatly, it is necessary to screen the sand through a construction sieve. It is a device specially used for sieving powdery substances and filtering fluids. The size of the sieve hole is smaller than the size of one of the two mixed substances and larger than the size of the other, so that the effect of sieving can be achieved. Sieves play a vital role in the process of screening building materials from granules to powders, so si...
