A high-efficiency and safe screening equipment for iron powder impurity removal and classification

Abstract

The invention discloses grading and efficient safety screening equipment for iron powder impurity removing. The grading and efficient safety screening equipment comprises a feeding tube, a pulverizer,a screening box, a vibrating screening net, a guiding plate, a flow return tube, a solid transmission pump, an electromagnetic wheel, a scraper plate, a division plate, a first winnowing machine, animpurity outlet end, a first-grade iron powder outlet end, a second-grade iron powder outlet end and a three-grade iron powder outlet end; the top end of the screening box communicates with the feeding tube, the pulverizer is mounted above the feeding tube, the vibrating screening net is slantly arranged in the top end of the screening box, the lowest end of the vibrating screening net is connected with the flow return tube, the guiding plate is slantly arranged below the vibrating screening net, and the electromagnetic wheel is arranged below the lowest end of the guiding plate; the divisionplate is arranged below one side of the electromagnetic wheel, and the scraper plate is arranged on the other side of the electromagnetic wheel; and the first winnowing machine is arranged on the outer side of the division plate, and the first-grade iron powder outlet end, the second-grade iron powder outlet end and the three-grade iron powder outlet end are arranged at the bottom end of the screening box. According to the grading and efficient safety screening equipment for iron powder impurity removing, conducting of screening is facilitated, the working efficiency is improved, different particles of iron powder are separated and fall down from different outlet ends in a grading mode, using is convenient, and popularizing is facilitated.

Description

technical field [0001] The invention relates to a metallurgical equipment, in particular to a high-efficiency and safe screening equipment for impurity removal and classification of iron powder. Background technique [0002] Metallurgy is the process and process of extracting metals or metal compounds from ores, and using various processing methods to make metals into metal materials with certain properties. Metallurgy has a long history of development in our country, from the Stone Age to the subsequent Bronze Age, and then to the large-scale development of modern iron and steel smelting. The history of human development incorporates the development of metallurgy. Metallurgy, developed from ancient pottery. The first is copper smelting. The melting point of copper is relatively low. With the development of pottery, the working temperature required by pottery is getting higher and higher, reaching the melting point of copper. In the process of making pottery, in some pla...
