Iron-powder extraction machine of iron-containing powder

Abstract

The invention discloses an iron-powder extraction machine of iron-containing powder, which is used for extracting iron powder from powder containing the iron powder and belongs to recovery equipment of environmental-friendly waste products. The iron-powder extraction machine is characterized by comprising a crushing barrel (1) of a crushing mechanism, a blade (2), a magnetic rotating wheel (7) of a sorting mechanism, a scraping blade (8), collecting hoppers (16, 14 and 12), a motor (19), large and small stripy gears (23 and 26), large and small bevel gears (19 and 22) and large and small chain wheels (6 and 20) of a double-speed-change mechanism. The iron-powder extraction machine disclosed by the invention has the advantages that the arranged double-speed-change mechanism adopts a vertically-arranged motor, simultaneously is used as a power source for the crushing blade with high-speed and vertical type operation and the magnetic rotating wheel with low-speed horizontal operation; the arranged double-speed-change mechanism is directly and tightly arranged on a rotor shaft (24) of the motor in a sheathing manner by central holes of the large stripy gears (23) and the small bevel gears (22), and drives the blade and the magnetic rotating wheel respectively and simultaneously, so that the grinding and the cutting of an iron piece are achieved, the iron-containing powder in the grinding wheel powder is extracted and recycled, and further both the effects of changing wastes into valuables and managing the environment are achieved.

Description

Technical field [0001] The invention relates to an iron powder extraction machine for extracting iron powder from iron powder-containing powder, which belongs to environmental protection waste product recovery equipment. Background technique [0002] As we all know, for iron parts grinding and cutting steel, the grinding wheel powder that is ground or cut contains a large amount of iron powder, and these iron powders can be returned to the furnace, which is a pure raw material for steelmaking. Water or moisture is easy to agglomerate, and the hardness is very hard. It is very difficult to extract the iron powder in the existing technology, and it can be said that it has never been done before. Therefore, this iron powder is not recovered, and is all wasted in vain, which not only causes waste of raw materials, but also iron powder is very easy to produce oxidation reaction with water molecules to generate ferric oxide (Fe 2 o 3 ), that is, rust. Rust dissolves in water to ...

Problems solved by technology

[0002] As we all know, for iron parts grinding and cutting steel, the grinding wheel powder that is ground or cut contains a large amount of iron powder, and these iron powders can be returned to the furnace, which is a pure raw material for steelmaking. Water or damp is easy to agglomerate, and the hardness is very hard. It is very difficult to extract the iron powder in the existing technology. It can be said that it has never been done before.

Therefore, this iron powder is not recovered, and is all wasted in vain, which not only causes waste of raw materials, but also iron powder is very easy to produce oxidation reaction with water molecules to generate ferric oxide (Fe 2 o 3 ), that is, rust. Rust dissolves in water to form rust water. According to the law of immortality, this kind of fine water will pollute water resources and the environment for a long time, and will cause it to enter the human body through various channels, resulting in an increase in the iron content in the human body. It can cause excessive storage of iron in the human body, resulting in serious hazards such as increased incidence of various diseases such as heart and liver diseases, diabetes, and certain benign and malignant tumors due to potential excessive storage of iron in the body
