The vibrating sieving device is characterized in that a screen mesh form long and strip shape, and the screen surface is formed by overlapping a waved screen surface assembly which is composed of an elastic screen rod, a guide rod, a bracket and a guide mesh. When the vibrating sieving device screens materials with an irregular shape and multiple edge angles, the screen surface can not be clogged, and the screening efficiency is enhanced.
Description
The utility model relates to a kind of vibration screening device, and it can be widely used in the grading screening of various materials.Particularly the particular design by compass screen surface solves the problem that difficult screened material stops up compass screen surface.
In the production technology, extensively adopting to exchange vibrating motor is the vibratory sieve of exciting source at present, and the compass screen surface of these vibratory sieves adopts the meshed planar structure mostly, or compass screen surface adopts the sieve aperture of other shape.Do not have the screening of corner angle material for smooth surface, still can operate as normal finish screening.In the ordinary course of things, all contain the irregular and multangular material of profile in the material of screening, be exactly that contained ratio is fewer, very short time will be reduced screening efficiency because of the irregular and multangular material of profile blocks mesh, soon the mesh more than 70%～90% is blocked, has lost sieving actoion.
The purpose of this utility model is exactly in order to overcome the defective that existing vibratory sieve stops up compass screen surface easily, a kind of novel compass screen surface structural vibrations sieve to be provided.It does not only produce the compass screen surface clogging during ganoid material in screening, particularly can not produce the compass screen surface clogging in the screening profile during irregular and multangular material yet.
The utility model task is finished as follows by special compass screen surface structural design: compass screen surface adopts long bar shaped screen hole, the trend of bar shaped screen hole is consistent with the forward motion direction of oversize material, helps like this falling into bar shaped screen hole and the material particles that leaks down in the end can be followed the oversize material and travelled forward together; And on oversize material movement locus, any position of bar shaped screen hole should not exist can hinder the proal parts of material particles in the bar shaped screen hole, the particle that falls into bar shaped screen hole is advanced in vibration can not be stuck owing to stopping.The compass screen surface that forms bar shaped screen hole must be a strip structure, can be easy to eject bar shaped screen hole for the particle that falls into bar shaped screen hole is advanced in vibration, and the parts that constitute the bar shaped compass screen surface should have certain elasticity, have adopted elastic screen bar for this reason.Bar shaped compass screen surface itself can also produce certain free vibration in being subjected to the exciting process of exciting source, with this shape that increases the amplitude of compass screen surface and change sieve aperture.Because the shape of sieve aperture constantly changes, make always loosening can not the blocking that contact between the particle that falls into sieve aperture and the compass screen surface, help particle and from sieve aperture, eject, the amplitude increase more helps the ejection of particle in addition.
The bar shaped compass screen surface is owing to limit by support strength and rigidity to do very longly, for this reason the bar shaped compass screen surface can sectional making, by adorning, every section bar shaped compass screen surface is a screening surface assembly.The bar shaped screen hole of each screening surface assembly should be opening at the oversize material port of export, adopts watt shape joint form to connect between each section screening surface assembly, forms complete compass screen surface.The oversize material port of export of screening surface assembly forms watt shape joint form of opening and screening surface assembly, can effectively avoid the proal parts of material particles occurring stopping in the bar shaped screen hole of connection place, the particle that falls into bar shaped screen hole is produced in the screening surface assembly connection place successively to returning the phenomenon of blocking sieve aperture.A watt shape joint form makes material movement can produce to lap-joint to stir in addition, and material fully contacts compass screen surface, has improved screening effect.
The utility model is compared the beneficial effect that is had with background technology: the material of screening different shape is non blinding screen all, thereby improves screening effect and efficient greatly, and this is an outstanding advantage of the present utility model.Secondly, produce when moving on compass screen surface owing to material and stir, material fully contacts compass screen surface, has improved screening effect.In addition, the particular design of compass screen surface structure makes material non clogging screen hole, no longer needs to alleviate the obstruction of sieve aperture with the method that strengthens exciting force, thereby has reduced the consumption of exciting source electric energy and the life-span of having improved exciting source and vibratory sieve.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of bar shaped watt shape compass screen surface vibratory sieve
Fig. 2 is screening surface assembly structure and an overlap joint schematic diagram thereof of forming compass screen surface
With reference to Fig. 1, exciting source ［ 10 ］ is connected on the screen box ［ 9 ］ by load, screening surface assembly ［ 8 ］ composition compass screen surface is equipped with in bottom in the screen box ［ 9 ］, and the exciting force that exciting source ［ 10 ］ produces makes screening surface assembly ［ 8 ］ produce vibration by screen box ［ 9 ］, and the material on the compass screen surface is sieved.Screen box ［ 9 ］ is installed on the support ［ 12 ］ by shock absorber ［ 11 ］, and shock absorber ［ 11 ］ prevention alleviating screen box ［ 9 ］ is passed to the vibration on the support ［ 12 ］.Compass screen surface is formed by screening surface assembly ［ 8 ］ overlap joint.
With reference to Fig. 2, screening surface assembly ［ 8 ］ comprising: elastic screen bar ［ 1 ］, guide rod ［ 2 ］, carriage ［ 3 ］, pressing plate ［ 4 ］, elastic layering ［ 5 ］, pilot hole ［ 6 ］, connecting plate ［ 7 ］.Elastic screen bar ［ 1 ］ in the screening surface assembly ［ 8 ］ is parallel evenly by dress, makes between the elastic screen bar ［ 1 ］ and forms bar shaped screen hole.The rear end of elastic screen bar ［ 1 ］ is pressed the front side that is fixed on carriage ［ 3 ］ by top pressing plate ［ 4 ］ and following elastic layering ［ 5 ］ by fastening bolt, and the front end of elastic screen bar ［ 1 ］ is unsettled not fastening.Carriage ［ 3 ］ is fastened on the sidewall of screen box ［ 9 ］ by the connecting plate ［ 7 ］ at two ends again.This draw bail, elastic screen bar ［ 1 ］ is except that being undertaken the forced oscillation by the exciting force that screen box ［ 9 ］, carriage ［ 3 ］ transmit by exciting source ［ 10 ］, and itself also produces free oscillation.When steady operation, elastic screen bar ［ 1 ］ will be in forced oscillation and free-running synthetic oscillatory regime.Quality and rigidity by the length and the thickness of adjusting elastic screen bar ［ 1 ］ are regulated elastic screen bar ［ 1 ］ make its intrinsic free oscillation frequency near forced oscillation frequency.Elastic screen bar ［ 1 ］ is in resonance state, and amplitude increases, and so both can improve screening effect, and the material that falls into sieve aperture is ejected, and non blinding screen.In addition and since elastic screen bar ［ 1 ］ only an end fix, each elastic screen bar ［ 1 ］ can not be synchronized with the movement fully at vibration processes, this just causes bar shaped screen hole in vibration processes generation change of shape.The change of shape of bar shaped screen hole will make to drop in the bar shaped screen hole and exist relative motion between the material particles and elastic screen bar ［ 1 ］ always, material particles is always loosening in bar shaped screen hole, make material particles can not be stuck between elastic screen bar ［ 1 ］ and stop up sieve aperture.
Be to overlap and be fixed on the madial wall of screen box ［ 9 ］ between each section screening surface assembly ［ 8 ］ by watt shape form.When each section screening surface assembly ［ 8 ］ overlaps in screen box ［ 9 ］, is to reduce height layer by layer by screen box ［ 9 ］ rear end to front end oversize material outlet screening surface assembly ［ 8 ］, and the minimum distance that (does not relate to guide rod ［ 2 ］) between each layer screening surface assembly ［ 8 ］ should be greater than the width of bar shaped screen hole, overlaps in the oversize direction of motion between the elastic screen bar ［ 1 ］ of each section screening surface assembly ［ 8 ］.So just guarantee in the bar shaped screen hole can not exist and hinder the proal parts of material particles in any position.Owing to form opening between elastic screen bar ［ 1 ］ free end of compass screen surface resistor ［ 8 ］, screening surface assembly ［ 8 ］ watt shape joint form just makes bar shaped screen hole be exported by the oversize material that the compass screen surface rear end extends to the compass screen surface front end always, forms long bar shaped screen hole again.So just make the material that drops in the bar shaped screen hole shake by the outlet of its end, and can not be stuck in the end of every section screening surface assembly ［ 8 ］ bar shaped screen hole, extend and the obstruction compass screen surface to its head end successively again along bar shaped screen hole.There is distance between each layer screening surface assembly ［ 8 ］ levels, material movement forms drop to screening surface assembly ［ 8 ］ lap-joint, material makes the compass screen surface upper materials produce to stir with the lower floor material in the landing process to mix, in screening process, make the material of compass screen surface levels fully touch compass screen surface like this, increased screening effect.
It is unsettled that elastic screen bar ［ 1 ］ one end is fixed an end, and the free end of elastic screen bar in vibration processes ［ 1 ］ may produce the vibration or the displacement of horizontal direction, and the bar shaped screen hole at this position is broadened, and the piece phenomenon takes place to leak.Unsettled end at elastic screen bar ［ 1 ］ vertically is equipped with guide rod ［ 2 ］ for this reason, is provided with pilot hole ［ 6 ］ at the rear side of carriage ［ 3 ］, and guide rod ［ 2 ］ of each group screening surface assembly ［ 8 ］ is inserted in the pilot hole ［ 6 ］ of the one group of screening surface assembly in front ［ 8 ］.The spacing of pilot hole ［ 6 ］ equates that with the spacing of elastic screen bar ［ 1 ］ guide rod ［ 2 ］ can slide in pilot hole ［ 6 ］.So neither influence the free vibration of elastic screen bar ［ 1 ］, prevent effectively that again elastic screen bar ［ 1 ］ from producing horizontal movement.Guide rod ［ 2 ］ can be welded on the end of elastic screen bar ［ 1 ］, also can be directly bent by an end of elastic screen bar ［ 1 ］ to form.In order to guarantee the joint form of screening surface assembly ［ 8 ］, guide rod ［ 2 ］ should have with a certain distance from elastic screen bar ［ 1 ］ free end end points.
