Description

Technical Field

[0001] This utility model belongs to the technical field of rare earth polishing material processing equipment, and in particular relates to a rare earth polishing elemental silicon powder dissolution and stirring device. Background Technology

[0002] Rare earth polishing elemental silicon powder, as a high-performance polishing material, is widely used in surface polishing processes in fields such as optical glass, semiconductor wafers, and precision ceramics. In its production and processing, the dissolution and stirring process is one of the key steps. This process requires adding rare earth polishing elemental silicon powder and a specific solvent (such as acidic solution, alkaline solution, or special solvent) into a stirring container in a certain proportion. The two are then fully mixed by a stirring device to form a uniform polishing slurry, providing qualified raw materials for subsequent polishing processes.

[0003] A Chinese patent application with publication number 202022717802.8 discloses a stirring device for dissolving elemental silicon powder, including a reaction vessel, a stirring device, a feed inlet, a discharge outlet, a control valve, a fixing device, a heat source inlet, and a hydrogen exhaust pipe; the stirring device includes a variable frequency motor, a stirring column, and a shearing wheel; the feed inlet is located on one side of the stirring device. This utility model has a simple structure, is easy to operate, and accelerates the dissolution of elemental silicon powder, effectively improving the conversion rate of elemental silicon powder;

[0004] Although this patent can accelerate the dissolution of elemental silicon powder, it still has the disadvantages of slow feeding speed and inconvenient cleaning of the stirring container and stirring mechanism. In actual production, rare earth polishing elemental silicon powder has the characteristics of fine particles and low bulk density, which makes it easy to cause bridging and blockage during the feeding process of traditional dissolution and stirring devices, resulting in slow and uneven feeding speed. The above-mentioned patent is an integrated structure, and there are many dead corners for cleaning at the connection between the inner wall of the container and the stirring shaft and stirring blades. Moreover, the stirring blades are mostly fixed installations, which are difficult to disassemble. After each processing, the operator needs to use special tools to reach into the container for cleaning, which is not only time-consuming and labor-intensive, but also difficult to completely remove the residual polishing slurry.

[0005] To address these issues, we have provided a rare-earth polishing elemental silicon powder dissolution and stirring device. Utility Model Content

[0006] The purpose of this invention is to provide a rare earth polishing elemental silicon powder dissolving and stirring device. By combining the stirring component and the lifting component, it solves the problems of existing rare earth polishing elemental silicon powder dissolving and stirring devices, which are mainly of an integrated structure, resulting in slow material feeding and difficult cleaning.

After the material is poured into the inner cavity of the material distribution plate, the rotating material distribution plate evenly throws the material out, and the rotating stirring frame efficiently stirs and mixes the material.

[0010] The present invention is further configured such that a limiting ring is fixedly connected to the top of the placement seat, and the inner wall of the limiting ring is in contact with the surface of the stirring cylinder. When the stirring cylinder is placed into the inner cavity of the limiting ring at the top of the placement seat, the limiting effect of the limiting ring can improve the stability of the stirring cylinder placed on the top of the placement seat.

[0011] The present invention is further configured such that feeding ports are provided on both sides of the top of the fixed frame, and the inner cavity of the feeding port is provided with a sealing plug.
