Problems solved by technology

However, due to the "dead zone" of the exciting force, the biggest defect is that the ability to "relieve jamming" and reduce "sieve blockage" and "sieve paste" is far inferior to that of circular vibration type sieves.
Especially in the work of de-intermediation, if the liquid medium has a certain viscosity, the linear vibrating screen cannot be well adapted

Embodiment 1

[0022] Embodiment 1: The novel mining vibrating screen of the first structure

[0023] The vibrating screen adopts the structure of two excitation motors. like figure 1 and figure 2 As shown: there is a vibrating screen box 1, which is supported on the base 4 of the vibrating screen by four rubber damping springs 5 ​​with variable stiffness. The center of mass of the box 1 ensures the stability of the vibrating screen box 1 during startup and operation. The vibrator 2 composed of two vibrating motors is installed on the vibrating screen box 1 through the support shaft 7. The vibrator is based on the force center theory of the inertial vibrating screen and the non-equal mass diameter product following self-synchronization and synchronous state stability theory. Work to realize the translational elliptical mode shape motion of the single-mass biaxial self-synchronized translational elliptical vibrating screen. The automatic control electrical appliance switch box 3 is insta...

[0024] Embodiment 2: the novel mining vibrating screen of the second structure

[0025] The vibrating screen adopts the structure of four excitation motors. like image 3 and Figure 4 As shown: there is a vibrating screen box 1, which is supported on the base 4 of the vibrating screen by four rubber damping springs 5 ​​with variable stiffness. The center of mass of the box 1 ensures the stability of the vibrating screen box 1 during startup and operation. The vibrator 2 composed of four side plate vibrating motors is directly installed on the side plate of the vibrating screen box 1, and the four side plate vibrating motors are connected in pairs by the connecting shaft 7. Center theory and non-equal mass-diameter product following self-synchronization and synchronization state stability theory work to realize the translational elliptical mode shape motion of single-mass multi-axis self-synchronized translational elliptical vibrating screen. The automatic control electric...

The invention has the advantages of energy saving, high efficiency, simple structure, convenient manufacturing, low cost, high popularization value and the like.

Description

technical field [0001] The invention relates to vibrating screening and conveying mechanical equipment, in particular to a novel energy-saving and high-efficiency mining vibrating screen. Background technique [0002] Due to the limitations of the traditional design theory, for a long time, the inertial vibrating screens used in mining projects are limited to circular vibration sieves, linear vibration sieves and general elliptical vibrations. : [0003] The circular vibrating track vibrating screen has a strong ability to "unblock" the "blocking" phenomenon of critical particles on the screen (or sieve plate), and shake the critical solid particles that block the holes of the screen or sieve plate. up or down. However, the serious rebound of solid particles on the screen surface and the excessively large ejection angle reduce the speed of sand conveying and chip removal. At the same time, the wear on the screen surface increases, reducing the service life of the screen o...
