Description
Technical field
The utility model relates to a kind of vibratory sieve, is specifically related to a kind of vibratory sieve with cambered surface screen cloth.
Background technology
All can use sieve in industries such as medicine, food chemistry, cosmetics and mineral aggregate and coals material is screened, be vibratory sieve for the equipment of automatic sieving at present substantially.
Vibratory sieve in the market mainly comprises motor, screen box, vibrator, resiliency supported etc., motor through V-belt or shaft coupling make vibrator eccentric block produce High Rotation Speed, the eccentric block of running produces centrifugal force, excite screen box to produce the motion of certain amplitude, on-the-sieve material is subject to the momentum that screen box passes to and produces continuous sling movement on the compass screen surface tilting, in the process that material and compass screen surface meet, make the particle that is less than sieve aperture thoroughly sieve, thereby realize classification.Existing vibratory sieve amplitude can not conveniently regulate, and need to change the weight of vibrator eccentric block, each like this eccentric block that all needs to install different eccentric weight in the situation that needing various amplitude, inconvenient operation for obtaining various amplitude.In the course of work, Dust Capacity is many, and noise is large, serious environment pollution.Operating personnel's work under bad environment, serious the healthy of operating personnel that affect.
In addition, existing vibratory sieve productivity ratio is low, screening efficiency is low, generally only has 50-60%, also easily stop up sieve aperture, control material and enter on compass screen surface, speed can not be too fast, and screening reject needs cleaning, the screen box that has some vibratory sieves for conveniently go out screening reject be set to skewed, but also easily make ungarbled material along with screening reject is drawn off.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of vibratory sieve that noise is little, screening effect good, convenience regulates and screening reject easily draws off that sieves.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of vibratory sieve with cambered surface screen cloth, comprise support, screen cloth and motor, the top of described support is set side by side with at least two spaces and parallel arc-shaped guide rail, described screen cloth is the groove shape screen cloth that cross section takes the shape of the letter U, the bottom of described screen cloth is provided with roller and is erected at movingly on described arc-shaped guide rail by described roller, on the power output shaft of described motor, be connected with crank, on described crank, be connected with rocking bar, one end of described rocking bar is stretched to described screen cloth and is connected to the edge of described screen cloth towards described motor one side by revolute pair, on described support, be also provided with screening reject discharging guide plate, after described screen cloth is pushed, its edge towards described motor one side can join with the top of described screening reject discharging guide plate.
Further, described revolute pair is to form for the through hole coordinating with described rotating shaft by being located at the rotating shaft of described screen cloth edge and being opened in described rocking bar end, spaced apartly on the body of rod at described rocking bar other end place is provided with multiple connecting through holes of distribution along its length.
Further, the both sides of described screen cloth length direction are also respectively provided with one for stoping the position-limited rack of the relative support sideslip of described screen cloth, and described position-limited rack is fixed on described support.
Further, the wheel face place of described roller is coated with one deck rubber layer.
Further, described support below is provided with target grain size material conveyer belt, and the below of described screening reject discharging guide plate is provided with screening reject conveyer belt.
The beneficial effects of the utility model are:
The utility model is pushed away, is drawn the groove shape curved screen being positioned on arc-shaped guide rail by crank and rocker mechanism, and the ogive that makes curved screen back and forth do high frequency centered by the center of circle of arc-shaped guide rail rocks, and utilizes the collision of material and screen cloth to reach the object of screening.
Because the vibratory sieve in the utility model not adopts traditional eccentric, therefore can avoid producing noise because of vertical tremor.
Can also come respectively to sieve frequency and to sieve amplitude when sieving to regulate by the length that changes the rotating speed of crank and change rocking bar between screen cloth and crank, relatively traditional vibratory sieve have improved adjusting difficulty.
In addition, screen cloth is being pushed to certain position place, and its edge can dock mutually with the top of screening reject discharging guide plate, and in the time having more screening reject in screen cloth, screening reject can be drawn off screen cloth along screening reject discharging guide plate.
Brief description of the drawings
Below in conjunction with accompanying drawing, the vibratory sieve with cambered surface screen cloth of the present utility model is described further.
