Pretreatment device for graphite powder and block recovery

Abstract

The invention discloses a pretreatment device for graphite powder and block recovery. The pretreatment device comprises a first pressing plate, a second pressing plate and a liquid containing pool located below the first pressing plate and the second pressing plate. An extrusion space is formed between the first pressing plate and the second pressing plate, one side of the extrusion space is provided with a feeding end, and the other end is provided with a discharging end; and a plurality of first spray pipes capable of stretching into the extrusion space are arranged on the plate face of the side, close to the extrusion space, of the first pressing plate, correspondingly, a plurality of second spray pipes capable of stretching into the extrusion space are arranged on the plate face of the side, close to the extrusion space, of the second pressing plate, and spray openings are formed in the first spray pipes and the second spray pipes in a staggered manner, and are communicated with a pressure cleaning source through pipelines. The device aims to remove impurities on graphite powder and blocks to obtain a clean recycled material, thereby facilitating subsequent retreatment.

Description

technical field [0001] The invention relates to the technical field of graphite recovery, in particular to a pretreatment device for graphite powder and block recovery. Background technique [0002] One of the main uses of graphite parts (products) is to produce refractory materials, including refractory bricks, crucibles, continuous casting powders, mold cores, molds, detergents and high temperature resistant materials. In recent years, two important changes in the refractory industry are the widespread application of magnesia-carbon bricks in the lining of steelmaking furnaces, and the application of aluminum-carbon bricks in continuous casting. The graphite refractory is closely connected with the steelmaking industry, and the steelmaking industry around the world consumes about 100% of the refractory material. [0003] Graphite crucible is a refractory graphite crucible mainly used in smelting special alloy steel, melting non-ferrous metals and their alloys, which is ma...

Problems solved by technology

Graphite products usually produce a lot of waste during processing. If they are not recycled, it will cause waste of resources on the one hand and environmental pollution on the other. However, graphite waste such as graphite powder, particles, blocks, etc., usually contains other impurities Such as dust, sawdust, and mud and oil stains adhering to graphite blocks, in order to improve the quality of subsequent graphite waste recycling, it is necessary to design a pre-treatment device for recycling graphite powder and blocks
