Description

Technical Field

[0001] The utility model relates to the technical field of steel slag processing equipment, in particular to a processing device for enhancing the activity of steel slag. Background Art

[0002] Steel slag is a byproduct of the steelmaking process. It is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts generated by the reaction of these oxides with solvents. There are two main ways to comprehensively utilize steel slag as a secondary resource. One is to recycle it in the factory as a smelting solvent, which can not only replace limestone, but also recover a large amount of metallic iron and other useful elements; the other is to use it as a raw material for manufacturing road construction materials, building materials or agricultural fertilizers.

[0003] During the current processing of steel slag, although the iron impurities are separated by a magnetic separator, some iron-containing waste will still be broken into small particles such as iron powder after passing through a roller press, which are mixed in the steel slag and are difficult to remove. Therefore, we propose to design a processing device that enhances the activity of steel slag. Utility Model Content

[0023] A motor 5 is fixedly connected to one side of the outer wall of the mounting frame 3. The driving shaft of the motor 5 passes through the mounting frame 3 and is fixedly connected to a camshaft 6. The end of the camshaft 6 away from the motor 5 is connected to the bearing on the inner wall of the mounting frame 3. The camshaft 6 is located inside the conveyor belt 4 and close to the top of the conveyor belt 4. The camshaft 6 rotates in the conveyor belt 4 to drive the surface of the conveyor belt 4 to vibrate, thereby assisting in separating steel slag from iron waste.

[0024] The outer wall of the mounting frame 3 is fixedly connected with a debris removal frame 7, and one side of the outer wall of the debris removal frame 7 is fixedly connected with an electric push rod 8. The telescopic end of the electric push rod 8 penetrates the debris removal frame 7 and is fixedly connected with a scraper 9. The top of the debris removal frame 7 is fixedly connected with an electromagnet 10. The scraper 9 has a U-shaped cross section. The scraper 9 is made of high-strength plastic. The U-shaped scraper 9 is convenient for gathering the iron powder waste adsorbed on the surface of the electromagnet 10. A wear-resistant thin plate is provided on the bottom surface of the electromagnet 10. The wear-resistant thin plate is fixed to the electromagnet 10 by bolts. When the wear-resistant thin plate is worn, it can be disassembled and replaced.

[0025] An impurity removal opening 11 is provided at one end of the impurity removal frame 7 away from the electric push rod 8, wherein the scraper 9 corresponds to the exit of the impurity removal opening 11, so that the scraper 9 can scrape the iron waste out of the impurity removal opening 11.

[0026] When in use, firstly connect the motor 5, the electric push rod 8 and the electromagnet 10 to the external power supply, put a sufficient amount of steel slag that has been subjected to magnetic separation treatment into the roller press 1, and crush the steel slag by means of two roller pressing shafts in the roller press 1. By adjusting the pressure of the roller press 1, the pressure of the roller press 1 is matched with the particle size of the steel slag, so that the material can be fully ground.

[0027] After grinding, the slag material falls to the top of the conveyor belt 4, and the motor 5 is started to drive the camshaft 6 to rotate. When the outer protrusion of the camshaft 6 fits with the inner top of the conveyor belt 4, the conveyor belt 4 can be lifted up, and the camshaft 6 rotates at a high speed to make the top of the conveyor belt 4 and its corresponding part vibrate, thereby driving the slag to vibrate, so that the residual iron powder in the material is separated from the slag, and the electromagnet 10 is started to generate magnetic force, which can adsorb the iron powder in the slag to the surface of the electromagnet 10, and further remove impurities from the slag to improve the activity of the slag.
