Energy-saving and environment-friendly sand stone screening system

Abstract

The invention discloses an energy-saving and environment-friendly sand stone screening system. The lower portion of a cylinder body is provided with a water outlet; an air cylinder is arranged at thebottom end of the interior of the cylinder body, a screening cylinder is arranged over the air cylinder, and a first spring is connected between the bottom end of the screening cylinder and an air cylinder piston rod; a feeding port is arranged on the side face of the upper end of the screening cylinder, a discharging port is arranged at the bottom end of the screening cylinder, and the feeding port and the discharging port penetrate out of the outer side of the cylinder body through a feeding pipeline and a discharging pipeline respectively; a screen mesh is arranged in the screening cylinder; multiple hanging rings are fixed to the cylinder wall of the top end of the screening cylinder, the corresponding ends of multiple second springs are fixed to the inner wall of an upper end cover body of the cylinder body, hanging hooks are fixed to the other ends of the multiple second springs, and the multiple hanging hooks hook the hanging rings; and a water spraying device is installed on the inner wall of the cover body of the cylinder body and used for spraying water to a gap between the inner wall of the cylinder body and the outer wall of the screening cylinder. According to the energy-saving and environment-friendly sand stone screening system, the structure is simple, design is reasonable and novel, operation is easy, manpower is saved, the efficiency is high, and energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of sand screening, in particular to an energy-saving and environment-friendly sand screening system. Background technique [0002] At present, artificial sand and gravel screening is generally supported by a screen on the ground, and people use shovels to screen. This kind of sand and gravel screening method is labor-intensive for workers, and workers feel physically tired after screening for a period of time. The stone screening device has a complex structure, is not easy to operate, and the screening effect is average. In addition, a large amount of dust is likely to be generated when sand and stone are screened. Contents of the invention [0003] The purpose of the present invention is to provide an energy-saving and environment-friendly sand screening system in order to make up for the defects of the prior art. [0004] The present invention is achieved through the following technical solutions: [0...
