Abrasion-resistant impact-resistant square-hole sand screen

By using elastic balls to impact and remove clogging sand and gravel in a square-hole sand and gravel screen, and combining this with a locking component to adjust the bounce range, the problem of clogging by wet and sticky materials is solved, achieving efficient screening and continuous production.

AI Technical Summary

Technical Problem

Existing square-hole sand and gravel screens are prone to clogging when processing wet and sticky sand and gravel materials, which leads to a decrease in screening efficiency and requires shutdown for cleaning, increasing labor intensity and affecting the production process.

Method used

The system uses elastic balls that bounce irregularly between a fixed box and a square-hole screen to remove clogging sand and gravel through impact. The bouncing range of the elastic balls can be adjusted by a locking component, and the screening is driven by a vibrating motor to improve cleaning efficiency.

Benefits of technology

It effectively prevents screen clogging, improves screening efficiency, reduces downtime for cleaning, reduces the labor intensity of operators, and maintains production continuity.

Abstract

This utility model relates to the field of sand and gravel screening technology and discloses a wear-resistant and impact-resistant square-hole sand and gravel screen, including a base, a screen box, and a fixed box, as well as several elastic balls. The fixed box is fixedly installed below the screen box and is connected to the base by four return springs. A vibration motor is provided at the bottom of the fixed box to drive the fixed box to vibrate. A square-hole screen is provided inside the screen box, and several sets of connecting components for restraining the elastic balls are provided inside the fixed box. Several locking components are provided at the bottom of the fixed box to fix the connecting components to the fixed box. The elastic balls bounce irregularly between the fixed box and the square-hole screen, impacting the square-hole screen and the sand and gravel blocking it. The impact causes the sand and gravel to detach from the square-hole screen and return to the screen or fall into the fixed box. By driving the traction rope, the bouncing range of the elastic balls is restrained. Each elastic ball is responsible for a certain area, thereby improving the cleaning efficiency.
