A quartz sand particle screening device

Abstract

This utility model discloses a quartz sand particle screening device, which includes a screening box comprising a box body and a feeding hopper. The feeding hopper is fixed to the top of the box body, and an opening is provided on the front of the box body. The feeding hopper guides the material to fall evenly and enters the screen. The opening facilitates material discharge. The device utilizes a vibrating motor to generate vibration, which in turn causes the screen and frame to vibrate through the deformation of a spring seat, thus screening the material on the screen. The frame vibration also causes a fixed ball to move via a fixed rod. The fixed ball then moves a moving rod within a guide block, which in turn moves a pusher plate on the feeding hopper. This device can push away material adhering to the feeding hopper, solving the problem of material adhering to the hopper and causing poor feeding or blockage, thus reducing manual intervention.

Description

Technical Field

[0001] This utility model relates to a screening device, specifically a quartz sand particle screening device, belonging to the field of quartz sand particle screening technology. Background Technology

[0002] Quartz sand particles are a hard, wear-resistant, and chemically stable silicate mineral, mainly composed of silicon dioxide. They come in various colors, including white, yellow, and gray, and are mostly irregularly shaped granules. The particle size ranges widely, from a few micrometers to several millimeters. They possess excellent high-temperature resistance, insulation, and corrosion resistance, and are widely used in various industries such as glass, ceramics, casting, chemicals, and construction, making them an important industrial raw material.

[0003] Quartz sand particle screening is a process of separating quartz sand using a vibrating screen according to particle size requirements. During screening, the quartz sand vibrates on the screen surface; particles smaller than the screen openings pass through the screen, while larger particles remain on the screen surface, achieving coarse-fine separation. The screen opening size needs to be adjusted according to the application scenario (such as glass manufacturing, filter media, etc.), while also considering the impact of quartz sand moisture content and impurity content on screening efficiency to ensure uniform particle size after screening and meet the material standards of different industries.

[0004] In existing vibrating screens, feeding is mostly accomplished through a feeding hopper. However, due to the small angle of the hopper's incline or its rough surface, some quartz sand particles easily adhere to it, leading to poor feeding or blockage, affecting screening efficiency and continuity, and increasing the frequency of manual intervention. Therefore, a quartz sand particle screening device is proposed here. Summary of the Invention

[0005] This invention proposes a quartz sand particle screening device that can push the material attached to the hopper, solving the problem of material adhering to the hopper and causing poor feeding or blockage, and reducing manual intervention.

[0007] It also includes a screening mechanism, which is set inside the box. The screening mechanism includes a frame, and a screen is installed in the frame. The screen screen screens the material according to the aperture size, so that the material that meets the particle size requirements can pass through, thereby achieving material separation.

[0008] A vibration motor is installed at the bottom of the frame, and a spring seat is also fixed at the bottom of the frame. The spring seat is fixed to the inner wall of the box. The vibration motor provides vibration power, drives the screen and the frame to vibrate, and causes the material to move on the screen.

[0009] The frame is provided with a ramp, and the screening mechanism also includes a material protection plate, which is fixed on the frame. The ramp and the material protection plate extend to the outside of the box through an opening. The material protection plate is provided to prevent the material from overflowing from the ramp after screening.

A fixed ball is fixed to the lower end of the moving rod. The fixed ball contacts the fixed rod. An L-shaped protective plate is fixed on the moving rod. Furthermore, an elastic telescopic rod is installed between the moving rod and the inner wall of the box. The elastic force of the elastic telescopic rod drives the moving rod to reset.

[0011] The movable rod is installed inside the box via a linkage component. A pusher plate is fixed on the movable rod. The pusher plate is in contact with the inner side of the hopper. The pusher plate can move on the pusher plate under the drive of the movable rod, pushing away the material attached to it. The pusher plate is made of steel plate with a thickness of 1-2mm.
