Novel internal vibration type vibrating screen

Abstract

The invention provides a novel internal vibration type vibrating screen comprising a screen outer ring, spring supports and springs. The novel internal vibration type vibrating screen further comprises connection shafts, motors, reinforcing rings, bottom screens, platens and side screens. The vibrating screen is composed of an inner screen and the screen outer ring. The inner screen is composed of the reinforcing rings, the bottom screens, the platens and the side screens. The inner screen is connected with the motors through the connection shafts and is driven. The connection shafts are fixed to motor bottom plates through pressing plates and shaft end baffles. A dustproof cover, a supporting plate and a reinforcing plate are arranged between each motor bottom plate and the screen outer ring. The spring supports and the springs are arranged at the bottom of the screen outer ring. The other ends of the springs are connected with the inner screen. The novel internal vibration type vibrating screen has the beneficial effects that design is ingenious, the fault rate is low, maintenance expenses are low, work is more reliable, the internal vibration type structure is adopted so that resonance can be effectively prevented, the screen is kept balanced, stable simple harmonic vibration is output, and the double-layer screen structure is adopted so that it can be ensured that materials are sufficiently circulated and impurities are effectively filtered out.

Description

technical field [0001] The invention relates to the technical field of vibrating screens, in particular to a novel internal vibration vibrating screen. Background technique [0002] The vibrating screen is a device that makes materials smaller than the screen hole fall from the screen through the reciprocating motion of the screen, and is widely used in the screening of materials. Existing vibrating screens usually include two or more layers of screen mesh, and resonance needs to be avoided during vibration. Because the resonance amplitude will increase rapidly, the support drive spring will be seriously overloaded and its life will be shortened. Therefore, when driving the two screens, two driving devices are often used to drive the two screens respectively. However, the price of driving devices such as motors or hydraulic rods is relatively high, and such a structure will indirectly increase the cost of material screening.
