Description

A kind of combined woven screen vibrating screen
Technical field
The utility model belongs to mining machinery and makes the field, especially belongs to the woven screen vibratory sieve and makes field, the particularly manufacturing of combined woven screen vibrating screen.
Background technology
The vibratory sieve of assembling woven screen is the mine ore dressing common equipment, woven screen generally is made as tension type, and the same direction of two side direction is pricked the limit and become 45 degree, adopts strong oval head square neck bolt and tensioning plate to be strained and fixed to both sides, the centre certain altitude that raises up makes the work that connects together of itself and screen frame (unit).
In the actual use, screen cloth often occurs because of poor rigidity, rate of tension deficiency, excessive vertical and horizontal length, the asynchronous vibration of screen cloth and screen frame (unit) causes the central sill and the mutual friction damage of crossbeam of screen cloth and screen frame (unit), even damages whole screen box.Screen cloth damages needs whole Zhang Genghuan, and renewal cost is bigger, and productivity effect is poor, the cost height.
The utility model content
The utility model discloses a kind of combined woven screen vibrating screen according to the deficiencies in the prior art, by improving the screen making structure, adopts new fixing means to solve above-mentioned deficiency.The utility model is achieved through the following technical solutions.
A kind of combined woven screen vibrating screen, involving vibrations device, screen box, woven screen, wherein: described screen box comprises crossbeam, central sill, end plate, side plate, and end plate and side plate constitute screen frame (unit), and screen frame (unit) has central sill in the middle of vertically, laterally at least two crossbeams is arranged; The woven screen cross section is Z-shaped, and each vibratory sieve is made of two woven screens at least, and the Z-shaped two ends of woven screen are fixed on side plate and the central sill, upwards pricks the limit on side plate, pricks the limit on central sill downwards.
Described woven screen is pricked the limit on side plate one side direction, screen frame is fixed on the side plate, and woven screen is positioned at screen frame top, and woven screen is pricked edge direction upwards, and tensioning plate is fixed on the side plate by half-round head square neck bolt and to the side plate woven screen that is strained and fixed.
Described woven screen is pricked the limit downwards at central sill, and central sill is made of U-lag and backing plate welding, and woven screen is hooked in downwards in the U-lag groove, and increased pressure board above the woven screen passes the U-lag fixation clip with bolt woven screen is fixed.Preferred employed U-lag both sides slope inwardly 60 the degree, length of side 40mm is about wide 60mm suitable for reading.
Further each vibration screen is made of 4 to 10 woven screens, and the joint overlaps 20-30mm between the woven screen of the same side, central sill both sides.
Further central sill bundle position, limit, vibratory sieve cross section woven screen middle part is higher than side plate bundle position, limit, both sides, the low arc in high both sides in the middle of woven screen integral body in vibratory sieve cross section constitutes.
Further screen box vertically has two rubber strips; Lay respectively at the central sill both sides, the centre of central sill and side plate is below the woven screen.
The tensioning plate of said fixing woven screen is continuously or separates and be interrupted.Promptly use on the side plate of both sides continuously or separate the tensioning plate that is interrupted, all or at interval one section one section ground is fixed the bundle limit that the braided steel wire screen cloth makes progress, and half-round head square neck bolt installs and fixes tensioning plate at interval.
The U-lag of said fixing woven screen is continuously with pressing plate or separates interruption.Use is continuous or separate U-lag and the pressing plate that is interrupted, and whole or one section one section ground, interval is fixed the downward bundle limit of braided steel wire screen cloth, passes the bolt of U-lag fixation clip and installs at interval.
Above-mentioned woven screen can be the braided steel wire screen cloth, also can be the screen cloth that other material is made by braiding.
Installation steps: after assembling fixes screen box, at first begin to install woven screen from discharging opening, the screen cloth tensioning is layered on the vibratory sieve discharging opening limit, prick the close side plate that the limit makes progress, the downward U type that catches on groove, second screen cloth only needs to get final product at the overlapping 20-30mm of screen cloth joint, and other assembling form is the same with first.Load onto tensioning plate, pressing plate respectively, earlier suitable pretension tensioning plate, the clam member bolt tightens up the tensioning plate bolt at last more again.
In sum, the utility model is by reducing every screen mesh size, change mesh structure, adopt new fixing means to make braided steel wire screen cloth vibratory sieve have following helpfulness: one whole screen cloth changes several little screen clothes into and has overcome and screen cloth occurs because of poor rigidity, rate of tension deficiency, excessive vertical and horizontal length issue, every little screen cloth distortion reduces, and screen cloth and screen frame (unit) vibration are more synchronous; Z-shaped mesh structure and new fixing means and structure make screen cloth fixing more convenient, carry out local replacing according to every screen cloth situation easilier, save cost, have improved operating efficiency; The fixing means of Z-shaped mesh structure U-lag on central sill and structure make braided steel wire screen cloth vibratory sieve keep original arcuate structure, fix and remove and install conveniently; And the Z-shaped structure of screen cloth is hooked the intilted limit of U-lag, has utilized the toughness of material to make intensity of sieve-mesh better, and is also more firm by the bolting of U-lag; Because of screen cloth is fixed on the central sill, no longer include monoblock screen cloth and central sill and when vibration, produce friction, screen cloth increases service life, has saved cost, has improved operating efficiency; Vertical two rubber strips of screen box further make screen cloth laterally increase support, and the screen cloth distortion reduces, and screen cloth and screen frame (unit) vibration are more synchronous.
