Description

Technical Field

[0001] The invention relates to the technical field of mine screening, and in particular to an intelligent three-axis elliptical vibrating screen. Background Art

[0002] The three-axis elliptical vibrating screen is composed of three parallel vibrating shafts. One end of the vibrating shaft located on one side of the screen box is equipped with three gears that mesh with each other with a speed ratio of 1. When the vibrating screen is working, the motor belt transmission device drives the three gears of the exciter to rotate. Since the three shafts are equipped with counterweight plates with equal eccentric mass and the same eccentric radius, and are synchronously connected by gears with equal parameters, the motion trajectory of the screen box is elliptical, that is, the synthetic motion trajectory of the circular motion trajectory of the single-axis vibrating screen and the linear motion trajectory of the double-axis vibrating screen. The elliptical motion trajectory can make the material have a higher running speed and increase the output of the equipment.

[0003] During the use of the vibrating screen, problems such as failure of buffer components, cracking of the screen frame, uneven distribution of screened materials, and "locking" of bearings due to heating often occur, resulting in overload operation, abnormal vibration, and unplanned shutdown for repairs of the vibrating screen equipment, which seriously affects the normal production of the production line. The quality of maintenance cannot be guaranteed, thereby increasing the unit product cost. In addition, failure and damage of the vibrating screen buffer components cause the vibrating screen equipment to be in an abnormal vibration working state for a long time, causing immeasurable damage to the screen box, seriously affecting the service life of the vibrating screen. The number of operations and maintenance will also increase accordingly, thereby increasing the labor intensity of workers. In addition, during the operation and maintenance of the entire line, sometimes the production line operates far below the rated load for a long time, and the production capacity of the vibrating screen does not match the actual production capacity, resulting in increased ineffective consumption of the vibrating screen and increased unit energy consumption of finished products, which does not meet the requirements of energy reduction and emission reduction.

[0004] The technical problem to be solved by the present invention is: to provide an intelligent three-axis elliptical vibrating screen with status monitoring, fault warning, equipment operation status monitoring, automatic adjustment of operation status according to production capacity, reduction of maintenance costs, and reduction of labor intensity of workers.
