Novel single-mass vibrating screen

Abstract

The invention relates to a novel single-mass vibrating screen. The novel single-mass vibrating screen comprises main parts such as a single-mass ultra-wide multilayer screen-plane screen box, a split-type large-span vibration exciter which is installed in a seat-plug manner, a silicon oil damping vibration attenuation spring, a slurry backward excitation device, an automatic energy-saving life-extension control hardware-software system and a machine base. By adopting the ultra-wide multilayer screen box, not only can the processing capacity of the slurry be increased, but also the solid-liquid separation flow is increased; by adopting the split-type large-span vibration exciter, not only can the stress of the vibration exciter and the screen box be improved, but also the vibrating screen is not subjected to the restriction of the width of the screen box; the vibration exciter is installed in a seat-plug manner, and a tensile bolt and an anti-shear bolt are adopted, so that the loosening of the bolt can be effectively prevented; the screen box is installed on the base by adopting the silicon oil damping vibration attenuation spring, so that the vibration attenuation and the noise reduction can be better carried out; by adopting the automatic energy-saving life-extension control hardware-software system, two or more vibration exciters can be alternately powered on and off according to the requirement, so that the electric power can be effectively saved, and the service life of a motor in the vibration exciter can be prolonged; by adopting the slurry backward excitation device, the processing capacity and the processing effect for materials can be further increased, and the self-cleaning effect of the screen plane can be improved.

Description

technical field [0001] The invention relates to a new single-body vibrating screen, which is suitable for petroleum drilling engineering, mining engineering, shield engineering and other screening industry departments that need to use a single-body inertial vibrating screen for solid-liquid separation or solid particle classification and transportation. Background technique [0002] A new single-mass vibrating screen is used for solid-liquid separation or solid particle grading and conveying screening. At present, the screen boxes of this equipment are mostly single-layer or double-layer screen surfaces; Due to the limitation of the span of the vibration motor, it is impossible to further increase the width of the screen surface and the length of the length of the screen surface; It is best to prevent the loosening of the bolts; the whole screen is extremely unsatisfactory in the face of increasingly high-density and higher-viscosity mud; the self-cleaning problem of the scr...

[0002] A new single-mass vibrating screen is used for solid-liquid separation or solid particle grading and conveying screening. At present, the screen boxes of this equipment are mostly single-layer or double-layer screen surfaces; Due to the limitation of the span of the vibration motor, it is impossible to further increase the width of the screen surface and the length of the length of the screen surface; It is best to prevent the loosening of the bolts; the whole screen is extremely unsatisfactory in the face of increasingly high-density and higher-viscosity mud; the self-cleaning problem of the screen, especially the high-mesh screen, has not been solved; After the power of the upper vibrator or the vibrating motor starts to work in a steady state after the whole screen is started, there will be a problem of excess power, etc.

In mining engineering, in order to make the screening effect of solid particle classification and transportation more ideal, and also to further improve the screening rate of screening materials to increase the processing capacity, the application of multi-layer vibrating screens is being vigorously promoted at present. However, the multi-layer mining vibrating screen also faces the same "bottleneck" problem caused by the long-span exciter
