Abstract
The utility model relates to a vibration type pressure screen. A cylindrical screen net is arranged in a shell through an elastic film sheet in a suspending manner, a high-frequency excitation electromagnet acts on a supporting plate, the supporting plate drives a screen net cylinder to act the same high-frequency vibration so as to facilitate grains or fibers and the screen net not to be attached or adhered, accelerate the separation of different materials and improve the separation efficiency. The vibration type pressure screen disclosed by the utility model is the improvement on a traditional liquid medium separation device in paper-making industry, food industry, pharmacy industry, chemical industry and other corresponding fields.
Description
Technical field
The utility model relates to a kind of liquid medium separator, specifically is meant the pressurized screen that has the dither effect, belongs to liquid medium separation equipment technical field.
Background technology
In papermaking, food, pharmacy, chemical industry and other corresponding field; Particle or fiber that often need the size in the liquid medium, shape and proportion is different separate from liquid medium; At present; The capital equipment of realizing aforesaid liquid medium separation purpose is screen centrifuge and selectifier; Because screen centrifuge and selectifier are that a columnar screen cylinder is installed in circular housing, there are sieve aperture or sieve seam in the surface of screen cylinder, rotor is installed or near several rotors of the installation screen cylinder surface in the screen cylinder; The effect of the periodicity positive pressure that is produced when getting into centrifugal force that the slurry in the screen drum produced in the rotor rotation or rotor rotation is stitched through sieve aperture or sieve down, the time impurity reach the purpose of separation.There are the defective that manufacturing process is complicated, installation accuracy is high in this pressurized screen or selectifier, simultaneously, owing to structural reason, sieve aperture or sieve seam easy blocking, separative efficiency is lower, and fault rate is higher, and proportion different particle or fiber effects are relatively poor for separating.
Summary of the invention
The purpose of the utility model is: a kind of oscillatory type pressurized screen is provided, overcomes that existing screen centrifuge is complicated with the existing manufacturing process of selectifier, installation accuracy is had relatively high expectations, sieve aperture or sieve seam easy blocking, separative efficiency is lower, fault rate is higher, separate different particle of proportion or the relatively poor defective of fiber effects.
The utility model realizes that the technical method that above-mentioned purpose adopted is: a kind of vibration pressure sieve; It comprises: loam cake, flexible sheet, screen cloth tube, shell, supporting plate, hinge, bearing pin, base, electromagnet, upper flange, lower flange; On base, install and fix shell; Install and fix the screen cloth tube above the supporting plate, be fixed with flexible sheet with upper flange and lower flange respectively, be fixed on the upper and lower opening position of shell around the bottom flexible sheet of the upper oral part of screen cloth tube and supporting plate at the upper oral part of screen cloth tube and the bottom of supporting plate; Position suitable for reading at shell is equipped with loam cake; Bottom at supporting plate installs and fixes hinge, installs and fixes electromagnet in the bottom of base, and electromagnet armature is hinged through bearing pin and hinge.
Beneficial effect: the utility model is because after adopting technique scheme, can overcome effectively that existing screen centrifuge is complicated with the existing manufacturing process of selectifier, installation accuracy is had relatively high expectations, sieve aperture or sieve seam easy blocking, separative efficiency is lower, fault rate is higher, separate different particle of proportion or the relatively poor defective of fiber effects.
Description of drawings
Accompanying drawing is the structure principle chart of the utility model;
Shown in the figure: 1, loam cake; 2, flexible sheet; 3, screen cloth tube; 4, shell; 5, supporting plate; 6, hinge; 7, bearing pin; 8, base; 9, electromagnet; 10, upper flange; 11, lower flange; A, material inlet; B, screenings outlet; C, discharging opening.
The specific embodiment
On base 8, install and fix shell 4; Install and fix screen cloth tube 3 above the supporting plate 5; Be fixed with flexible sheet 2 with upper flange 10 and lower flange 11 respectively at the upper oral part of screen cloth tube 3 and the bottom of supporting plate 5; Be separately fixed at the upper and lower opening position and the end opening position of shell 4 around the bottom flexible sheet 2 of the upper oral part of screen cloth tube 3 and supporting plate 5, loam cake 1 be installed, install and fix hinge 6 in the bottom of supporting plate 5 at the position suitable for reading of shell 4; Install and fix electromagnet 9 in the bottom of base 8, the armature of electromagnet 9 is hinged through bearing pin 7 and hinge 6.
The course of work of the utility model is: slurry that will be to be screened is input to by the screen cloth 3 of tubular and the enclosure space of being made up of shell 4 from the material inlet (a) that is arranged on the shell 1; Under the filtration of screen cloth 3, slag charge flows out from screenings outlet (b), and screens the centre of the screen cloth 3 of the liquid material entering tubular after pressing; The dither of electromagnet; Impel particle or fiber and screen cloth not to adhere to or adhesion, quicken the separation between the different material, improved the efficient of separating.
