Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ore production technology, and in particular relates to an ore screening device. Background Technology
[0002] Ore refers to naturally occurring metals, metal oxides, and salts that have reached a level of engineering and smelting that are usable by humans. Common ores include gold ore, iron ore, and copper ore. When processing ores, screening is usually required to obtain ore particles of different sizes.
[0003] The existing authorized public account CN114308632A discloses an ore screening device for mineral processing, including an overall ore screen structure. The overall ore screen structure includes a main ore screening chamber, an ore screening frame, an ore screen support base, and a screen plate cleaner. The main ore screening chamber includes a screening chamber body, and the ore screening frame is installed inside the screening chamber body, dividing the interior of the screening chamber body into a screening chamber and a fine material discharge chamber. The ore screen support base is located below the screening chamber body. Inside the screening chamber body of this invention, a screen plate cleaner is provided directly below the ore screen plate. By holding the screen plate cleaner by hand and rolling it inside the cleaner's groove, the protrusions on the surface of the screen plate cleaner can penetrate and clean the rectangular grooves inside the ore screen plate. The cleaning is quick and convenient, regardless of the span of the screening chamber body. At the same time, the use of a spliced, split ore screen plate avoids the need to replace the entire ore when the ore screen plate is partially damaged. However, the aforementioned ore screening device for mineral processing has an open structure, in which the ore screen plate is installed horizontally. When screening the ore, a large amount of dust is generated, which leads to a significant increase in dust particles in the surrounding environment, causing air pollution and harming on-site operators. Therefore, it is necessary to provide an ore screening device to solve the above problems. Utility Model Content
