Abstract

The invention discloses a screening device and a using method for mixture reproduction for petroleum asphalt, and relates to the technical field of the petroleum asphalt. The screening device for mixture reproduction for the petroleum asphalt comprises a rack, wherein a reducing motor is arranged at the top of the left wall of the rack, and the output shaft of the reducing motor is fixedly connected with one end of a driving rod by a coupling, one end, away from the reducing motor, of the driving rod is movably connected with the top at the left side of the right wall of the rack, and an eccentric rotating wheel is sleeved on the driving rod, and the bottom of the eccentric rotating wheel is slidingly connected with the top of a contact plate. The screening device for mixture reproductionfor the petroleum asphalt solves the problems of poor shaking stability and poor service life of a vibration mechanism in the prior art by the cooperative setting of the reducing motor, the driving rod, the eccentric rotating wheel, an upper box mechanism and a lower box body, and by the cooperative setting of a horizontal shaking mechanism to drive a lower linkage mechanism to move back and forthrepeatedly.

Description

technical field

[0001] The invention relates to the technical field of petroleum asphalt, in particular to a screening device for reproducing petroleum asphalt mixture. Background technique

[0002] After the asphalt pavement is aging, it can also be recycled and regenerated. The quality of the recycled material can be effectively controlled by screening. For example, the Chinese authorized patent announcement number is: CN205917571U, a kind of multi-directional screening equipment for recycling recycled materials on asphalt pavement, including inclined settings. Screen box, the screen box is set on the load-bearing pier through the spring assembly, and the spring assembly is respectively set on the lower and upper parts of the two sides of the screen box. When the screen box performs multi-directional compound helical vibration, it is beneficial to the multi-directional movement of small particles of asphalt in the screen assembly, but the stability of the components used t...
