Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of modified asphalt processing, in particular to a raw material filtering and screening device for modified asphalt. Background Art
[0002] Modified asphalt is an asphalt binder made by adding external additives (modifiers) such as rubber, resin, high molecular polymer, ground rubber powder or other fillers, or taking measures such as mild oxidation processing of asphalt to improve the performance of asphalt or asphalt mixture. In order to improve the effect of modified asphalt processing, before adding the above raw materials, it is necessary to first use a filtering and screening device to subdivide the raw materials. The ones that pass the subdivision are put into production, and the ones that do not pass are re-broken. After searching, the patent with announcement number CN218079019U discloses a raw material filtering and screening device for modified asphalt. By starting the motor, the cleaning brush rotates on the screening mesh disk, and then the asphalt raw materials on the screening mesh disk can be filtered. Cleaning is carried out to improve the filtering and screening efficiency of the screening mesh disk, and at the same time, it also avoids the asphalt raw materials from clogging the screening mesh disk, ensuring the continuous operation of the device, thereby improving the filtering and screening efficiency of the device. However, this structural form set above the screening mesh disk is not only easy to hinder the filtering and screening effect, but also easy to make the raw materials stuck deeper in the inner bottom of the screening mesh disk, which further leads to a decrease in the filtering and screening efficiency of the screening mesh disk. For this reason, a modified asphalt raw material filtering and screening device is designed that is convenient for vibrating from the bottom in the form of circular vibration, ensuring smooth and effective filtering and screening while avoiding clogging of the inner bottom, further ensuring the efficiency of screening.

[0014] The modified asphalt raw material filtering and screening device is convenient to drive the vibrating screen mechanism to rotate circumferentially by a split rotary driving mechanism, and during the circumferential rotation, the circular wheel rotates circumferentially along the inner bottom of the filter screen, and synchronously drives the rotating sleeve and the eccentric wheel to rotate during the rotation. During the rotation of the eccentric wheel, the inner bottom of the filter screen can be intermittently knocked circumferentially, and the filter screen is vibrated during the knocking process to avoid clogging of the filter screen, and at the same time solves the problem of low filtering and screening efficiency caused by setting a cleaning structure from the top.
