Smelting waste brick making method

Abstract

The invention provides a smelting waste brick making method. The method uses a smelting waste brick making device, and the smelting waste brick making device comprises a stirring tank, a stirring mechanism, a discharge box, an extrusion mechanism, a vibration mechanism, a brick making mold and a support frame. The invention provides the smelting waste brick making method which can solve the following problems in the smelting waste brick making process that a, a large amount of slag is generated during metal smelting, the slag is directly discarded or serves as a roadbed material during pavingin a traditional treatment mode, only waste is simply utilized, and reutilization is not carried out aiming at the characteristics of the waste; and b, auxiliary materials such as lime need to be added for mixing and stirring in the process of making hollow bricks by utilizing the smelting waste, and most of existing stirring devices adopt double-horizontal-shaft structures, so that the energy consumption of the devices is high, the cost can be correspondingly increased, the devices can only be used for mixing and stirring, and the integrated design of mixing, stirring and extrusion forming isnot realized.

Description

Technical field [0001] The invention relate to that technical field of recycling proces of smelting wastes, in particular to a method for making brick from smelting wastes. technical background [0002] Smelting is a refining technology, which refers to the extraction of metals from ores by roasting, smelting, electrolysis and the use of chemical agents, so as to reduce the impurities contained in the metals or increase some components in the metals. In the process of smelting, various wastes will be produced, mainly including blast furnace slag and slag crushed stone produced by smelting. The metal slag produced can be used as raw materials of cement and coarse and fine aggregates of concrete. [0003] At present, there are the following problems in the process of making bricks from smelting wastes: a. A large amount of slag is produced during metal smelting, and the traditional treatment method is generally to directly discard or pave the roadbed materials, which is simply to u...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a method for making bricks from smelting waste, which can solve the following problems in the process of making bricks from smelting waste: a. A large amount of slag is produced during metal smelting, and the traditional treatment method is generally to discard it directly or use it as a roadbed when laying roads Materials, this kind of waste is simply used, and there is no reuse according to its characteristics; b. In the process of using smelting waste to make hollow bricks, auxiliary materials such as lime need to be added for mixing. The existing mixing device Most of them adopt a double-horizontal shaft structure. This kind of device consumes a lot of energy, which will increase the cost accordingly. This kind of device is often only capable of mixing and stirring, and has not realized the integrated design of mixing, stirring and extrusion molding.
