Vibrating screen for nucleating agent particle screening device

Abstract

The invention discloses a vibrating screen for a nucleating agent particle screening device. The vibrating screen for the nucleating agent particle screening device comprises a shell, a supporting frame, a screen body, an elastic element, a magnetic block, a vibrating motor, multiple layers of screen cloth and distributing channels. The supporting frame is located on the bottom surface of the shell and has the supporting function. The screen body, the elastic element, the magnetic blocks, the vibrating motor, the screen cloth and the distributing channels are all located in the shell. The elastic element is fixed to the bottom surface of the inner portion of the shell. The screen body is fixedly connected to the other end of the elastic element. The magnetic block is fixedly connected to one side of the screen body. The vibrating motor is arranged at the position close to the magnetic block. The distributing channels are arranged on the other side of the screen body. The multiple layers of screen cloth are arranged in the screen body. The distributing channels correspond to the outlet ends of the multiple layers of screen cloth. According to the vibrating screen for the nucleating agent particle screening device, the multiple layers of screen cloth and the discharging channels corresponding to the outlet ends of multiple layers of screen cloth are arranged, the nucleating agent particles of multiple specifications can be screened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of inoculant production, in particular to a vibrating screen used for inoculant particle screening equipment. Background technique [0002] Cast iron is basically a eutectic alloy composed of iron, carbon and silicon, of which carbon mainly exists in the form of graphite; to produce high-quality castings, it is crucial to control the morphology of graphite formed when cast iron solidifies and the matrix metal structure ;Inoculation treatment is one of the most important links in the production process; a good inoculation treatment can make the cast iron have a microstructure that meets the requirements, thereby ensuring the mechanical properties and processing properties of the casting; adding an inoculant to the liquid cast iron can form a large amount of The submicroscopic core promotes the formation of eutectic clusters in the liquid phase; when the eutectic solidification temperature is close to the eutectic solid...

Problems solved by technology

[0003] The inoculant is an additive that can promote the formation of graphite, reduce the tendency of whitening, improve the morphology and distribution of graphite, increase the number of eutectic groups, and refine the matrix structure. It is currently the most widely used 75 ferrosilicon inoculant; in the casting process , the molten iron in the ladle has a high temperature of about 1400 degrees Celsius. If there is powder in the inoculant, it will be oxidized and burned on the surface during the process of adding molten iron, and the inoculation effect cannot be achieved. Usually, the inoculant products are all particles with a particle size of 0.2mm or more. The particle size below 0.2mm is the dust loss. The more dust is produced, the greater the loss and the higher the cost; in the traditional inoculant production process, there will inevitably be powder, which is mainly transferred to the vibrating machine in the later stage of screening and bagging. Sieve screening, the screen of the vibrating screen has only two or three layers, the screening effect is not good, the size of the screened inoculant particles is small, and the production efficiency is low
