Deironing method for rubber powder and apparatus thereof

Abstract

The invention discloses a method and a device for removing iron in rubber powder. The method for removing iron is simple, simplifies rubber powder production process, and has a better iron removal effect. The device is simple in structure, convenient in installation and use, uniform in conveyed powder, and complete in iron removal. The method comprises the following steps: arranging iron removing devices in a process of conveying powder subjected to fine break and screen separation to a procedure; and arranging an equalizing device to equalize the powder before the powder is transmitted to the iron removing devices for iron removal. A first iron removal device comprises a conveyor belt a magnet arranged on a support and above the conveyor belt. A second iron removing device comprises a rolling shaft, an annular cylindrical magnet arranged on a roller of the rolling shaft and an equalizing plate arranged corresponding to the roller. A delivery hopper comprises a hopper body and an outward extending tongue plate connected with a material outlet end part of a bottom plate of the hopper body.

Description

Technical field: [0001] The invention relates to a method for removing iron from rubber powder and a device thereof. Background technique: [0002] In the process of using waste rubber, especially waste tire rubber, to prepare regenerated rubber powder, whether the rubber is crushed and the steel wire is clean is one of the keys that affect the quality of the regenerated rubber powder; the existing waste rubber powder and iron removal usually need to be installed. Special conveying device with iron removal device, such as setting a magnet in a certain part of the material conveying cylinder, the conveying cylinder is an increased conveying link that directly contacts the material, the powder making process is complicated, and because the materials conveyed to the iron removing device are not balanced , The material distribution does not correspond to the magnetic field intensity distribution of the magnet, which seriously affects the iron removal effect. At the same time, d...

[0002] In the process of using waste rubber, especially waste tire rubber, to prepare regenerated rubber powder, whether the rubber is crushed and the steel wire is clean is one of the keys that affect the quality of the regenerated rubber powder; the existing waste rubber powder and iron removal usually need to be installed. Special conveying device with iron removal device, such as setting a magnet in a certain part of the material conveying cylinder, the conveying cylinder is an increased conveying link that directly contacts the material, the powder making process is complicated, and because the materials conveyed to the iron removing device are not balanced , the material distribution does not correspond to the magnetic field intensity distribution of the magnet, which seriously affects the iron removal effect

At the same time, due to the unreasonable structure of the iron removal device, the separation of materials and iron filings is not clear, and the raw materials are easy to adhere to the iron removal device and mix with iron filings, resulting in poor separation effect, even after repeated separations. , low production efficiency, complex structure, inconvenient installation and use, high manufacturing cost
