Cement production raw material iron removal device

Abstract

The invention discloses a cement production raw material iron removal device in the field of cement production equipment, which comprises a driving roller. The outer surface of the driving roller is in transmission connection with a magnetic conveyor belt, the outer surface of the magnetic conveyor belt is in transmission connection with a conveyor belt, and the interior of the conveyor belt is in transmission connection with a driven roller; supports are fixedly connected to the two ends of the driven roller, a hopper is fixedly connected to one end of each support, a refining device is fixedly connected to the middle of each support, and an electromagnetic iron removal box is arranged at the bottom end of the driving roller. In use, the driving roller drives the conveyor belt to enable materials to ascend, and when the materials reach the highest position to be fed into the electromagnetic iron removal box, due to the action of the magnetic conveyor belt in the conveying belt, waste with high iron content is attracted to the conveyor belt to be conveyed downwards; when themagnetic conveyor belt moves upwards, the materials on the conveyor belt fall off without the action of magnetic force, so that the iron-containing waste can be preliminarily screened in the feeding process.

Description

technical field [0001] The invention relates to the field of cement production equipment, in particular to a device for removing iron from raw materials for cement production. Background technique [0002] At present, cement is a powdery hydraulic inorganic cementitious material, which can be hardened in air or water after being mixed with water to form a slurry. It is used to cement sand, stone and other granular materials into mortar or concrete. After an appropriate amount of water, it can become a plastic slurry, which can be hardened in air and water, and can firmly bond sand, stone and other materials together. Cement is especially suitable for making concrete, Precast concrete, fair-faced concrete, GRC products, adhesives and other special occasions are widely used in colored pavement bricks, permeable bricks, cultural stones, sculpture handicrafts, terrazzo, wear-resistant floors, putty, etc. The production and transportation of main raw materials require the use of...

Problems solved by technology

[0002] At present, cement is a powdery hydraulic inorganic gelling material. It can be hardened in air or water after being stirred into a slurry with water. It is used to cement sand, stone and other granular materials into mortar or concrete. If it is finely ground into powder, add After an appropriate amount of water, it can become a plastic paste, which can harden in air and water, and can firmly bind sand, stone and other materials together. Cement is especially suitable for making concrete, Precast concrete, fair-faced concrete, GRC products, adhesives and other special occasions are widely used in colored pavement bricks, permeable bricks, cultural stones, sculpture crafts, terrazzo, wear-resistant floors, putty, etc. In cement production, due to the The production and transportation of main raw materials require the use of a large amount of iron equipment, especially the mining and transportation of stone, which is inseparable from iron equipment. Therefore, a large amount of scattered iron or iron is mixed in the raw materials. If these iron objects cannot be removed, it will have a serious impact on the subsequent processing and production of cement, and even cause equipment damage.

[0003] A production line composed of a series of equipment for cement production, mainly composed of crushing and pre-homogenization, raw material preparation and homogenization, raw material transportation, preheating decomposition, cement clinker firing, cement grinding and packaging, etc., before cement raw material processing It must go through the iron removal process. The current main method is that before the cement raw materials enter the production line, the inspectors first use magnets and other magnetic tools to detect the iron substances in the raw materials. After the detection is completed, the raw materials enter the cement production process. Thereby the cement production efficiency is low, and the labor intensity of the detection work is also relatively large. Therefore, those skilled in the art provide a cement production raw material iron removal device to solve the problems raised in the above-mentioned background technology
