Abstract
The invention discloses a secondary vibration screening method for a screen surface, belongs to the field of vibration screening machines, and solves the problem that holes of the screen surface of a large-scale vibrating screen is easy to plug. In the screening method, a screening operation which can clear screen holes is performed on materials on the screen surface under the action that a screen frame vibrates according to designed work frequency and vibration amplitude and under the action of secondary vibration of the screen surface. The screen frame of the large-scale vibration screen is mainly formed by assembling two side plates, a plurality of lower beams and 2 to 4 upper beams; the screen surface is formed by arranging a plurality of screen plates; each screen plate is arranged on a support base on each lower beam of the screen frame; a side protecting plate is respectively arranged inside the side plate of the screen frame; a gap is reserved between each side protecting plate and each screen plate; a gap is reserved between each two adjacent screen plates of the screen surface; and a non-metal elastic material strip is respectively embedded between the side protecting plate and the screen plate as well as between the screen plates. The method has the characteristics of high screening performance, high screening efficiency and long service life, and can be used for screening operations of various materials and wet materials which are different to screen.
Description
Technical field:
The invention belongs to the vibration screening machinery field, mainly relate to material under the effect of operating frequency vibration that designs and sieve plate secondary vibration, produce instantaneous out-of-balance force, realize the compass screen surface secondary vibration method for sieving and the large-scale vibrating screen of not plug-hole screening.
Background technology:
Vibratory sieve is in the middle of running, and the phenomenon of stopping up sieve screen apertures takes place often, because vibratory sieve when screening operation, always has the material near mesh size to get lodged in the mesh, and easy to clean not; Adhesional wetting materiel also very easily stops up mesh in the process of screening.Because vibratory sieve is clocklike to carry out screening operation under the movement locus state, the material of plug-hole is difficult to change residing position, can only be stifled more serious more.More in addition material or bulk materials fall on the compass screen surface or on compass screen surface vibrosieve, compass screen surface and sill that compass screen surface is installed are also produced bigger impulsive force, produce destruction, reduced the service life of vibratory sieve.
Summary of the invention:
The purpose of this invention is to provide a kind of compass screen surface secondary vibration method for sieving and large-scale vibrating screen; This method makes the sieve plate of forming compass screen surface produce secondary vibration, has solved the problem of material plug-hole, has increased screening percentage; Also slowed down the impact of material to compass screen surface, the service life of having improved sieve plate simultaneously.
Compass screen surface secondary vibration method for sieving of the present invention is realized by large-scale vibrating screen, it is characterized in that: be installed in screen frame on the vibration damping support device under the driving of vibrator, by the operating frequency and the amplitude vibration of design; The sieve plate that spring is housed simultaneously produces secondary vibration under the effect of deadweight inertia force and material gravity; Compass screen surface produces instantaneous out-of-balance force under the effect of the operating frequency of secondary vibration and design and amplitude vibration, remove effectively and get lodged in the material in the sieve aperture, realizes the not screening of plug-hole.
Realize the large-scale vibrating screen of compass screen surface secondary vibration method for sieving, mainly be made up of screen frame, compass screen surface, vibrator, transmission gear for electric motor and vibration damping support device that vibrator is installed on the screen frame, screen frame is installed on the vibration damping support device.It is characterized in that: screen frame mainly is to be assemblied by two side plates, several sill and 2～4 entablatures; Compass screen surface is to be rearranged by the polylith sieve plate, and every sieve plate is installed on the base for supporting on the screen frame sill through the sieve plate spring; Inboard at the screen frame side plate is equipped with side guard plate, leaves the slit between side guard plate and the sieve plate; Leave the slit between the adjacent sieve plate of compass screen surface; For guaranteeing that the place, slit do not leak material, when the width in slit was big, place, between side guard plate and the sieve plate and the slit between sieve plate and the sieve plate studded with the non-metallic elastic material bar.
According to the size of screening raw meal particle size and the needs of forming, the sieve plate spring can be rubber spring, complex spring or metal disk spring; The metal embedded part of rubber spring through two ends and sieve plate are connected with base for supporting on the sill.Side at sieve plate is processed with groove, and the non-metallic elastic material bar at place, slit is to be set in the groove of sieve plate side between side guard plate and the sieve plate and between sieve plate and the sieve plate, and the shape of groove is circular arc or V-arrangement.Compass screen surface integral body is the shape of plane or arcs of recesses folding face, and the number of plies of compass screen surface is 1～3 layer.
The invention has the beneficial effects as follows that this method for sieving and large-scale vibrating screen can effectively prevent and clear up the problem of material plug-hole, and can make material that the impact of screen cloth is had certain cushioning effect.It is to adapt to more material, bulk materials or to the screening operation of the bigger material of sieve plate impulsive force that the sieve plate spring adopts the metal disk spring.With the service life of improving vibratory sieve greatly.It is good to have screen-penetrating performance, and the characteristics of the high and long service life of screening efficiency can be applicable to the screening operation of various difficult screened materials and adhesional wetting materiel.
