Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, specifically a multi-layer high-frequency screen for mineral separation. Background Technology

[0002] High-frequency screens are the main equipment used for screening and classifying mineral materials, separating solid and crushed ores. Existing high-frequency screens include a base, a screen box mounted on the base, and multiple springs between the screen box and the base. The springs are vertically arranged, with their two ends fixedly connected to the base and the screen box, respectively. An inclined screen plate is fixedly mounted on the screen box, with the feed end of the screen plate higher than the discharge end. A vibrator is fixedly mounted on the screen box to drive the screen box to vibrate on the base. During the separation process, the mineral material slides down to the discharge end of the high-frequency screen due to its gravity, completing the separation process during the descent. However, the mineral material stays on the screen plate for a relatively long time, which can easily lead to insufficient separation. Therefore, this utility model provides a multi-layer high-frequency screen for mineral separation. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-layer high-frequency screen for mineral fractionation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer high-frequency screen for mineral analysis, comprising a base and a screen plate mounted on the base. A screen mesh is fixedly installed on the inner side of the screen plate. A motor is fixedly installed on the screen plate via a fixing frame. A rotating shaft is fixedly installed on the output end of the motor. Multiple telescopic plate groups are fixedly installed on the rotating shaft. The telescopic plate groups are evenly distributed in the circumferential direction of the rotating shaft. The movable end of the telescopic plate group is in contact with the upper surface of the screen mesh.

[0005] Preferably, the telescopic plate assembly includes a fixed sleeve plate, a movable inner plate, and an elastic element; one end of the fixed sleeve plate is fixedly connected to the rotating shaft, the movable inner plate is slidably connected to the fixed sleeve plate, and the elastic element is disposed between the fixed sleeve plate and the movable inner plate.

[0006] Preferably, the elastic element is a spring, and the two ends of the spring are fixedly connected to the fixed sleeve plate and the movable inner plate, respectively.

[0007] Beneficial effects

Multiple telescopic plate groups are fixedly installed on the rotating shaft. The telescopic plate groups are evenly distributed in the circumferential direction of the rotating shaft. The movable end of the telescopic plate group is in contact with the upper surface of the screen, so that the ore can move on the screen for a longer time, and the ore is sorted more thoroughly, resulting in better sorting effect.

[0016] The following combination Figures 1 to 3 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0017] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please combine Figures 1 to 3 As shown, this utility model provides a multi-layer high-frequency screen for mineral sorting. The multi-layer high-frequency screen includes a base 1 and a screen plate 2 installed on the base 1. A screen mesh 3 is fixedly installed on the inner side of the screen plate 2. The high-frequency vibration of the screen plate 2 is a conventional technical means in the field, so it will not be described in detail here. A motor 5 is fixedly installed on the screen plate 2 through a fixing frame 6. A rotating shaft 9 is fixedly installed on the output end of the motor 5. Multiple telescopic plate groups are fixedly installed on the rotating shaft 9. The telescopic plate groups are evenly distributed in the circumferential direction of the rotating shaft 9. The movable end of the telescopic plate group is in contact with the upper surface of the screen mesh 3.

[0020] The telescopic plate assembly includes a fixed sleeve plate 4, a movable inner plate 7, and a spring 8; one end of the fixed sleeve plate 4 is fixedly connected to the rotating shaft 9, the movable inner plate 7 is slidably connected to the fixed sleeve plate 4, and both ends of the spring 8 are fixedly connected to the fixed sleeve plate 4 and the movable inner plate 7, respectively.

[0021] The length of the telescopic plate assembly is equal to half the width of screen 3. When the ore is conveyed to the top of screen 3, the ore covers half of screen 3. The telescopic plate assembly rotates upward on the half of screen 3 covered with ore. After the ore slides down into the rotation range of the telescopic plate assembly, the telescopic plate assembly will push the ore towards the top of screen 3 and drive some of the ore to the other side in the width direction of screen 3. The telescopic plate assembly on the other side moves towards the bottom of screen 3. The ore on the other side of screen 3 will detach from the telescopic plate assembly and slide down to the bottom of screen 3. During this process, the ore can move on screen 3 for a longer time, which can more fully separate the ore and improve the separation effect.
