Abstract
The invention discloses a screen surface supporting beating device for a vibrating screen, and belongs to the field of vibratory screening machinery. The problems of weak screen surface vibration strength, hole plugging caused by materials, low screening rate and the like of the vibrating screen are solved. The device mainly comprises a screen box, a screen surface and a beating device, wherein the beating device is provided with a plurality of supporting vibrating beating shafts contacting with the screen surface below the screen surface; the two ends of each supporting vibrating beating shaft are fixedly arranged on two side plates or side plate accessories of the screen box through elastic supports; regulation devices capable of displacing the elastic supports and the supporting vibrating beating shafts in a direction perpendicular to the screen surface are arranged in the vicinity of the elastic supports, and can be used for regulating the degree of tightness of contact between the supporting vibrating beating shafts and the screen surface; a layer of elastic abrasion-proof material is arranged on the surface of each supporting vibrating beating shaft. According to the device, the materials blocked in screening holes can be effectively removed, and the screening efficiency can be improved; in addition, a screening machine has the characteristics of high reliability, long service life and the like; moreover, the screen surface supporting beating device also has a function of supporting the screen surface and the materials, and is suitable to be arranged on various vibrating screens.
Description
Technical field
The invention belongs to the vibration screening machinery field, the oscillating screen of the difficult problem such as be mainly that the compass screen surface oscillation intensity in order to solve vibratory sieve is little, material plug-hole, screening percentage are low supports knocking device.
Background technology
Vibratory sieve is the screening to material by the compass screen surface vibration realizing on screen box and screen box, and oscillation intensity is larger, and its screening effect is better, but excessive oscillation intensity can make shorten the service life of vibratory sieve, earlier period damage occurs.So existing vibratory sieve, limited by rigidity, intensity and service life, its oscillation intensity is generally between 3-5g.If improve screening efficiency and the disposal ability of vibratory sieve, in the situation that do not increase the vibratory sieve specification, just need to improve rigidity and the oscillation intensity of Structure of Vibrating Screen.Desirable screening plant is that sieve nest moves under lower inertia force, and compass screen surface vibrates under high oscillation intensity.
Summary of the invention
The purpose of this invention is to provide a kind of oscillating screen and support knocking device, this device can make the sieve nest of vibratory sieve under lower oscillation intensity, and compass screen surface obtains higher oscillation intensity, effectively removes and is stuck in the material in sieve aperture, improves screening efficiency.
The present invention is achieved by the following measures, mainly by screen box, compass screen surface and knocking device, formed, it is characterized in that: described knocking device is provided with a plurality of support rapping shafts that contact with compass screen surface below compass screen surface, each two ends of supporting rapping shaft is fixed on two side plates or side plate annex of screen box by elastic support, described near elastic support, be provided with and can make elastic support and support the adjusting device of rapping shaft at vertical compass screen surface direction top offset, can adjust the degree of tightness state that rapping shaft contacts with compass screen surface that supports.Noise and the wearing and tearing of to clash into compass screen surface while in order eliminating, supporting the rapping shaft vibration and to produce, be provided with one deck elastic abrasion-proof material on the surface of support rapping shaft.Elastic support is comprised of metal-coating, elastic rubbery body and inner metal sleeve, and elastic rubbery body is between metal-coating and inner metal sleeve.
The invention has the beneficial effects as follows, oscillating screen supports knocking device, in the vibration of the sieve nest with vibratory sieve, support rapping shaft and can produce secondary vibration, ceaselessly beat compass screen surface, amplitude and the oscillation intensity of amplification compass screen surface, can make sieve nest under lower oscillation intensity, and compass screen surface obtains higher oscillation intensity.Effectively remove and be stuck in the material in sieve aperture, improve screening efficiency, screen(ing) machine has the characteristics such as reliability is high, long service life simultaneously.This compass screen surface supports knocking device and also plays the effect of supporting compass screen surface and material in addition, is applicable to be arranged on various vibratory sieves.
