Regenerated rubber powder production device

Abstract

The invention discloses a regenerated rubber powder production device. The regenerated rubber powder production device is characterized in that tyre blocks formed through rough crushing of a tyre are crushed into coarse particles through a rubber coarse crushing pulverizer firstly, and the coarse particles are subjected to magnetic separation. Compared with the method that rubber is crushed into powder are then subjected to magnetic separation, a mode adopted by the device has the advantages that a steel wire is not fully smashed into iron powder, the efficiency of magnetic separation is high, and the iron removing ratio is high; before the coarse particles are delivered to a rubber powder crushing pulverizer, the coarse particles are subjected to the magnetic separation through an all-magnetic roller, so that iron-containing rubber particles are completely removed, and the iron-containing rubber can be crushed by the rubber coarse crushing pulverizer, therefore, through two-time coarse crushing pulverizer by the all-magnetic roller, the removing ratio of steel wire can reach above 99%, consequently, the content of iron powder is finished rubber powder is greatly reduced, and the production efficiency is high; an elastic part of a second moving sieve is replaced by an oscillating structure which is composed of an oscillating arm and a door-shaped frame, so that the screening efficiency is high, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to a production device for regenerated rubber powder. Background technique [0002] At present, the process of using waste tires to produce rubber powder includes separating the waste tires from the ring, cutting them into strips and dicing, and then directly crushing the diced tires into fine powders of 30-32 meshes, and then passing the fine powders through magnetic Iron powder and rubber powder are selected. In this way, since the iron wire is directly crushed into iron powder, on the one hand, the wear and tear on the equipment is great; on the other hand, the iron powder is not easy to be completely removed in the magnetic separation, resulting in a large content of iron powder in the final product, which affects the quality of the final regenerated rubber. [0003] Secondly, at present, rubber particles are generally realized by vibrating screens during screening. Current vibrating screens, such as Chinese patents CN2020611...

Problems solved by technology

In this way, since the iron wire is directly crushed into iron powder, on the one hand, the wear and tear on the equipment is great; on the other hand, the iron powder is not easy to be completely removed in the magnetic separation, resulting in a large content of iron powder in the final product, which affects the quality of the final regenerated rubber

[0003] Secondly, at present, rubber particles are generally realized by vibrating screens during screening. Current vibrating screens, such as Chinese patents CN202061199U and CN202539070U, are mainly composed of a frame, a screening motor (or motor), a screen box and a screen mesh. The screen box is fixed on the top of the frame, and the two are connected by an elastic support, so there is a problem that after a period of use, the elastic support needs to be replaced, and the elastic support has a short service life
