Abstract

The invention discloses a relaxation sieve, comprising two sieve frames, an elastic sieve surface, a main vibration spring and an elastic connecting rod vibration exciter. The sieve surface beams of the two sieve frames are alternately arranged; the elastic sieve surface is mounted on the sieve surface beam; and the two sieve frames are connected together through the main vibration spring and the elastic connecting rod vibration exciter and mounted on a foundation through a damper spring. The relaxation sieve disclosed by the invention has the advantages of low energy consumption, low stress of the vibration exciter and low fault rate. The relaxation sieve can be widely applied to the industries such as energy, metallurgy, ceramics, building materials and chemicals.

Description

A kind of flip flop screen
Technical field
The present invention relates to a kind of screening plant, particularly a kind of flip flop screen.
Background technology
At present, vibratory sieve extensive use in industries such as the energy, metallurgy, pottery, building materials, chemical industry is mainly used in the classification of material.Sieve aperture is stopped up in the easy conglomeration of fine fraction viscous material through moisture, and its screening is the difficult problem of dry screening always; Flip flop screen has effectively solved the screening difficult problem of moist fine particulate level viscous material; But traditional flip flop screen power consumption is high, vibrator stressed big, and fault rate is high.
Summary of the invention
The present invention has remedied the deficiency of prior art, and a kind of flip flop screen is provided, and the power consumption of this flip flop screen is low, vibrator stressed little, and fault rate is low.
Device of the present invention is; It comprises two screen frames, elastic screen surface, main shake spring and elastic link vibrator; The compass screen surface crossbeam arranged alternate of two screen frames, elastic screen surface is installed on the compass screen surface crossbeam, and two screen frames link together through main spring and the elastic link vibrator of shaking.Two screen frames are installed on the ground through shock-absorbing spring.Two screen frames can be linear or banana-shaped.
During work; Two screen frames are done the rightabout vibration under the elastic link vibrator, be in the Near resonance oscillating state, and the distance inbreeding is replaced between the adjacent compass screen surface crossbeam of two screen frames; Elastic screen surface is done the tension and relaxation motion between the adjacent compass screen surface crossbeam of two screen frames; When elastic screen surface was tightened, the acceleration that material obtains was very big, helped material layering and passed through sieve.
Compared with prior art, the present invention has following beneficial effect:
1, power consumption of the present invention is low;
2, vibrator of the present invention is stressed little;
3, fault rate of the present invention is low.

The specific embodiment
In Fig. 1; A kind of flip flop screen 1 is provided; It comprises screen frame 2, screen frame 7, elastic screen surface 15, main shake spring 10 and elastic link vibrator 11, and screen frame 2 be double-deck screen frame with screen frame 7, and the crossbeam 8 of screen frame 7 passes hole 3 and crossbeam 4 arranged alternate of screen frame 2 on screen frame 2 side plates; Elastic screen surface 15 is installed on crossbeam 4 and the crossbeam 8; The master of the screen frame 2 spring beam 5 that shakes passes the hole 9 on the side plate of screen frame 7, and the master of screen frame 2 spring base 6 that shakes is arranged in the end of the main spring beam 5 that shakes, and the master that the main spring 10 that shakes is installed in screen frame 2 shakes between the side plate of spring base 6 and screen frame 7; The rod spring 14 of elastic link vibrator 11 is connected with screen frame 7; The eccentric shaft 12 of elastic link vibrator 11 is installed on the screen frame 2 through bearing block 13, and screen frame 2 is arranged on the ground through shock-absorbing spring 16 with screen frame 7, and motor 17 is connected with elastic link vibrator 11 through pulley apparatus 18.
In Fig. 2 to Fig. 4; A kind of flip flop screen 19 is provided; It comprises screen frame 20, screen frame 24, elastic screen surface 32, main shake spring 27 and elastic link vibrator 28, and screen frame 20 be the individual layer screen frame with screen frame 24, and the crossbeam 25 of screen frame 24 passes hole 22 and crossbeam 21 arranged alternate of screen frame 20 on screen frame 20 side plates; Elastic screen surface 32 is installed on crossbeam 21 and the crossbeam 25; The main spring 27 that shakes is installed between the side plate angle steel 26 of side plate angle steel 23 and screen frame 24 of screen frame 20, and the rod spring 31 of elastic link vibrator 28 is connected with screen frame 24, and the eccentric shaft 29 of elastic link vibrator 28 is installed on the screen frame 20 through bearing block 30; Screen frame 20 is arranged on the ground through shock-absorbing spring 33 with screen frame 24, and motor 34 is connected with elastic link vibrator 28 through pulley apparatus 35.
The invention discloses a kind of flip flop screen; Though more than enumerated less embodiment, for those of ordinary skill in the art, to some remodeling that the present invention did, improvement, replacement etc.; Perhaps above-mentioned embodiment is made any combination and variation, all drops within protection scope of the present invention.
