Description
Technical field
The present invention relates to a kind of vibratory sieve, specifically refer to a kind of filtration oil sieve plate.
Background technology
Vibratory sieve is to utilize the reciprocating rotary type that oscillator exciting produces vibrate and work.The upper rotation weight of oscillator makes compass screen surface produce plane whirling vibration, and lower rotation weight makes compass screen surface produce conical surface rotary vibration, and its symphyogenetic effect makes compass screen surface generation revolve again type vibration.Its oscillation trajectory is the space curve of a complexity, and this curve is projected as a circle at horizontal plane, and is projected as an ellipse on vertical plane.Regulate the exciting force of upper and lower rotation weight, can change amplitude; And regulate the space phase angle of upper and lower weight, can change the curve shape of compass screen surface movement locus and change the movement locus of material on compass screen surface.Vibratory sieve is mainly divided into linear vibrating screen, circular shale shaker, high frequency shale shaker, and vibratory sieve can be divided into single-shaft vibrating screen and dual-axis vibration sieve by the pattern of vibrator.Single-shaft vibrating screen is to utilize single unbalanced weight exciting to make screen box vibration, and compass screen surface tilts, and the movement locus of screen box is generally circle or ellipse; Dual-axis vibration sieve is to utilize synchronous different to rotating pair of unbalanced weight exciting, compass screen surface level or low-angle dip, and the movement locus of screen box is straight line.Vibratory sieve has the types such as inertia vibrating screen, eccentric vibrating screen, self-fixed centre shale shaker and hummer screen.
At present, punching sieve plate is after steel plate punching, to be directly welded on screen frame, processing and manufacturing is simple, but because bolt on sieve plate is easily loosening, screen frame bottom can bump with sieve beam, in short time, cause sieve plate to break, because the low sieve aperture of sieve-plate aperture ratio is easily stifled, add own wt and limit to cause and sieve beam generation phenomenon of rupture, when increasing, accident wasted again a large amount of human and material resources, have a strong impact on normal production ，Gei enterprise and brought negative effect.
summary of the invention
The object of the present invention is to provide a kind of filtration oil sieve plate, solve the problems such as punching sieve plate accident rate is high, screening efficiency is low.
Object of the present invention is achieved through the following technical solutions:
Use an oil sieve plate, comprise the sieve plate being obliquely installed, sieve plate, between the screen(ing) machine longeron tilting and the screen(ing) machine crossbeam of inclination, has a plurality of evenly distributed sieve apertures on described sieve plate, and the cross section of described sieve aperture is parallelogram; Between described sieve aperture, be provided with backing strip; Also comprise contiguous block, sieve plate is connected with screen(ing) machine longeron by contiguous block.The vibration sieve plate being obliquely installed is connected with outside screen(ing) machine by bolt, on screen(ing) machine, under the vibration of vibrator, drives sieve plate to sieve operation; But after the long-time vibration of sieve plate, sieve aperture has the cylindrical reverse frustoconic that weares and teares into, cause sieve plate material when work to be embedded in being difficult in sieve aperture through, and then stop up sieve aperture, have a strong impact on the screening efficiency of sieve plate; And when the screw bolt abrasion of fixed screen deck or loosening after, sieve plate can be done periodically flexing, constantly clashes into crossbeam, sieve plate fatigability is fractureed or shake and snap mouth; Screwed hole and contiguous block that the present invention arranges by sieve plate two ends match, sieve plate is connected with outside screen(ing) machine longeron bolt, can realizes flexibly connecting of sieve plate and outside screen(ing) machine longeron, can self cushion a part of active force, ensure that bolt is difficult for loosening, reduced the fault rate of screen(ing) machine; The backing strip arranging can be fastening by sieve plate, guarantees the stability of sieve plate work, and the sieve aperture of traditional sieve plate is vertical with the plane at sieve plate place, and sieve aperture of the present invention is vertical with horizontal plane, increases the saturating area of sieve, has improved the effect of screening.
Also comprise the vibration damping adhesive tape being arranged between described screen(ing) machine crossbeam and described sieve plate.For reducing further the interaction force between sieve plate and screen(ing) machine, on the crossbeam of screen(ing) machine externally, along flow direction of material, be provided with vibration damping adhesive tape, guarantee to keep relative static conditions between screen(ing) machine and sieve plate, improve the stability of screen(ing) machine work.
Described sieve plate comprises polyurethane rubber and is arranged at the steel skeleton in polyurethane rubber; Described backing strip is connected with steel skeleton.The steel skeleton of sieve plate casts in polyurethane rubber, gives full play to the performance of polyurethane elastomer, and sieve plate is carried out elasticity with sieve beam and linked, thereby has prevented the loosening of sieve plate; Polyurethane rubber sieve plate, in sieve vibration processes, can produce secondary vibration, is conducive to the self-cleaning of sieve aperture, and non clogging screen hole.
Described contiguous block consists of rubber, and described screen(ing) machine longeron is provided with groove, and contiguous block is placed in groove, and the bottom land of groove has tapped through hole, and bolt-through contiguous block coordinates with tapped through hole.During installation, be bolted, make sieve plate dismounting convenient, reduced the workload of safeguarding; The contiguous block arranging becomes being rigidly connected between sieve plate and longeron to flexibly connect, and particularly can adopt the contiguous block of the materials such as rubber to have the effect of self vibration damping, sieve plate is difficult for loosening, has reduced whole weight.
The top of described contiguous block is provided with annular protrusion, and annular protrusion surrounds the nut of described bolt.Annular protrusion can avoid nut after long-time use, to get rusty under moist environment, can carry out certain protection to bolt, strengthens the connective stability between sieve plate and screen(ing) machine longeron.
The angle of inclination of described sieve plate is 15 ° ~ 20 °.Compass screen surface gradient is relevant with sieve plate treating capacity and screening efficiency, and the gradient of sieve plate is larger, and its treating capacity is also larger, lower but screening efficiency connects; The gradient of sieve plate is arranged within the scope of 15 ° ~ 20 °, can make to reach between treating capacity and screening efficiency effective balance, when gradient is during lower than 15 °, the treating capacity of sieve plate is too low, make most drilling fluid can not get screening out processing, when gradient is during higher than 20 °, the screening efficiency of sieve plate is too low, sieve plate is stopped up, affect operating efficiency.
Described bolt is interior six side's dormant bolts.
The present invention compared with prior art, has following advantage and beneficial effect:
