Embodiment Construction

[0041] The following structural drawings and embodiments further illustrate the present invention.

[0042] As shown in Figure 1.

[0043] A method for preparing rubber powder from waste tires based on water jet technology, which comprises the following steps:

[0044] a. First put the waste tires on a rotating support, the rotating shaft of the rotating support is installed horizontally, and the waste tires are installed perpendicular to the horizontal shaft within the effective cutting range of the water cutting head with a water pressure greater than 200MPa, so that the waste tires are far away from the water. The distance of the cutting head is within the range of 1-10 cm, generally 4-5 cm is better;

[0045] b. Make the waste tire rotate at a slow speed, and at the same time make the water cutting head rotate and swing (the swing angle can be between 0-180 degrees relative to the tire rotation axis), or add linear motion to the rotating motion to control the rotation Th...

Abstract

The invention relates to a method for using waste tyre to prepare rubber powder based on water injection technique, and relative device. Wherein, it uses the impact energy of high-speed rotation flow of high-pressure multi-ejector over than 200MPa to cut the rubber of waste tyre, and adjusts the pressure of water to only break it into fine rubber powder, but not break the steel wire; therefore, the rubber and steel wire can be separated by minimum energy and high speed; and the separated rubber can be directly recycled.

Description

technical field [0001] The invention relates to a processing and recycling technology of waste tires, in particular to a method and a device for directly obtaining rubber powder by using water jet technology to process waste and used tires, in particular to a method and device for preparing rubber powder from waste tires based on water jet technology method and device. Background technique [0002] At present, with the rapid development of my country's national economy, the transportation industry has also entered a stage of rapid development. At the same time, due to the gradual improvement of living standards, the ownership of private cars is also on the rise. When people enjoy the convenience brought by the automobile industry, the following problems are that the number of automobiles increases, the production of tires and the demand for rubber increase, and the production speed of waste tires is also greatly accelerated. At present, the annual output of tires in my cou...
