Rapid treatment device for internal attachments of magnesium alloy smelting crucible and treatment method thereof

Abstract

The invention relates to a rapid treatment device for internal attachments of a magnesium alloy smelting crucible. The rapid treatment device comprises the crucible to be cleaned, a water purificationtank, a sedimentation tank, a plate-and-frame filter press, a high-pressure cleaning assembly, a slurry transfer assembly and a slurry residue supply assembly. According to the device and method, through improvement and optimization of a traditional water soaking and manual cleaning method and assisting of auxiliary mechanical means such as an auxiliary high-pressure water gun and the plate-and-frame filter press, cleaning of the attachments on the inner wall of the crucible after magnesium alloy smelting can be rapidly, efficiently and environmentally friendly achieved, the working efficiency is high, the water consumption is low, the manual labor intensity is low, and the treatment period is short; and meanwhile, wastewater and sludge are recycled, so that the practicability and the environmental protection property are better.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metal processing, and in particular relates to a fast cleaning device and a processing method for rapid cleaning of attachments on the inner wall of a crucible for smelting high-performance magnesium alloys and cleaned magnesium-containing metal and refining agent slurry. Background technique [0002] At present, the cleaning of the inner wall attachments in the crucible furnace commonly used in the prior art for magnesium alloy smelting and the treatment method for the magnesium-containing metal and refining agent slurry produced after cleaning are described as follows: There are a lot of salt substances attached to it, which affects its reuse. When processing, it is necessary to soak the crucible with water at a certain temperature (the soaking time is generally between 24h-48h). After soaking for a long time, the waste inner wall attachments containing refining agent and covering agent in ...

AI Technical Summary

Problems solved by technology

[0003] This method of processing the deposits on the inner wall of the crucible for magnesium alloy smelting mainly has the following disadvantages: 1. The crucible needs to be soaked for a long time, the treatment cycle is long, and the work efficiency is low, so that the utilization rate of the crucible is not high; 2. In the crucible During the multiple manual cleaning of the inner wall, it takes a lot of water to scrub the inner wall and continuously discharge the waste water. The water consumption is large, and the manual workload is large, the labor intensity is high, and the work efficiency is low; 3. A large amount of waste water generated by cleaning To occupy a large space for storage, the waste water is evaporated for a long time, and the residual sludge is bagged for centralized treatment

The treatment cycle is long and takes a lot of time. The water in the process cannot be effectively reused, and the site occupies a large area; 4. Due to the low content of magnesium alloy in the cleaning wastewater, intensive recycling cannot be carried out. Therefore, the situation of scattered stacking is prominent , resulting in a poor working environment and low environmental protection
