Vibrating sieve

Abstract

The invention provides a vibrating sieve, which consists of an underframe, springs and a vibrating box, wherein the underframe is a square frame, four corners of the underframe are respectively provided with bosses, each boss is fixed with a spring thereon, the upper end of each spring is connected with the bottom of the vibrating box, a bottom plate of the vibrating box is provided with a lower discharging port, there is an inclined plate discharging groove installed below the lower discharging port, the bottom plate is further provided with an installation plate, the installation plate is equipped with a sieve matched with the bottom plate, and there is further a vibrating motor installation plate below the inclined plate discharging groove. The beneficial effects are that the vibratingsieve is simple in structure, light in weight and small in required installation space; the vibrating sieve is provided with double discharging port and is provided with the sieve at the discharging ports, thereby enabling the screening and discharging to be more accurate; and the installation position of the vibrating motor is located below the lower discharging port, thereby being fasters in discharging.

Description

technical field [0001] The invention relates to a vibrating screen, in particular to a vibrating screen. Background technique [0002] The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. [0003] The vibrating sieve can divide the particles and powder into particle segments of different sizes. A single vibrating sieving machine can be equipped with 4 layers of screens, which can continuously separate 2-5 vibrating sieve particle grades and control a narrow particle size range; It can quickly remove the large particles or small particles with a low percentage of pulp and slag separation. [0004] Currently used vibrating screens usually pass water through the sieve girders to lower the temperature, but the sieve g...

AI Technical Summary

Problems solved by technology

[0004] Currently used vibrating screens usually pass water through the sieve girders to lower the temperature, but the sieve girders are mostly assembled and welded by section steel. Under the influence of long-term vibration, uneven cooling temperature changes and welding defects, water leakage and blasting occur from time to time, which directly affects production and use. , and the existing vibrating screen is heavy, unreasonable in structure, and low in screening efficiency
