Abstract
The invention relates to a high frequency vibrating and suction type pressure screen. Specifically, a cylindrical screen is hung within a housing by an elastic membrane, a mechanical high frequency vibrating device is installed and fixed at the bottom of the screen, and simultaneously, a spiral rachis is mounted in the center of the cylindrical screen and is in connection with an electromotor through a flexible coupling. The mechanical high frequency vibrating device makes the screen do identical high frequency vibration so as to make particles or fibers not attached to or adhered to the screen. Rotation of the spiral rachis in the center of the screen can generate an upward lifting attractive force which can speed up the separation of different materials, thus improving the separation efficiency. The pressure screen provided in the invention improves and enhances existing liquid medium separation devices in papermaking, food, pharmaceutical, chemical and other relevant fields.
Description
Technical field
The present invention relates to a kind of drawing-in type pressurized screen, particularly a kind of dither and drawing-in type pressurized screen belong to liquid medium separation equipment technical field.
Background technology
In papermaking, food, pharmacy, chemical industry and other corresponding field, often need be with the size in the liquid medium, particle or fiber that shape and proportion are different separate from liquid medium, at present, realize that the capital equipment that the aforesaid liquid medium separates 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, enter under the effect of the periodicity positive pressure that the slurry in the screen drum produced when centrifugal force that the rotor rotation is produced or rotor rotation by sieve aperture or sieve seam, impurity reaches the purpose of separation.Not only there are the defective of manufacturing process complexity in this pressurized screen or selectifier, and simultaneously, owing to structural reason, sieve aperture or sieve seam stop up easily, and 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 objective of the invention is to: a kind of dither and drawing-in type pressurized screen are provided, overcome that existing screen centrifuge and the existing manufacturing process complexity of selectifier, sieve aperture or sieve seam stop up easily, separative efficiency is lower, fault rate is higher, separate different particle of proportion or the relatively poor defective of fiber effects.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: columnar screen cloth is installed in enclosure by flexible sheet in underslung mode, install and fix mechanical type high-frequency excitation device in the bottom of screen cloth, simultaneously, one spiral rachis is installed in the centre of cylindrical screen, the spiral rachis is linked to each other with motor by flexible clutch.Mechanical type high-frequency excitation device makes screen cloth make identical dither, impel particle or fiber and screen cloth not to adhere to or adhesion, the spiral rachis produces lifting attraction upwards in the rotation in the centre of screen cloth, quicken the separation between the different material, improved the efficient of separating.
The course of work of the present invention 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 screening by after the liquid material enter the centre of the screen cloth (3) of tubular, spiral rachis (5) rotation produces lifting attraction upwards, discharge in the circular hole of liquid material after screening pressed by upper flange (12), mechanical type high-frequency excitation device makes screen cloth make identical dither, impel particle or fiber and screen cloth not to adhere to or adhesion, the spiral rachis is in the rotation in the centre of screen cloth, produce lifting attraction upwards, quicken the separation between the different material, improved the efficient of separating.
Beneficial effect: the present invention is because after adopting technique scheme, can overcome effectively that existing screen centrifuge and the existing manufacturing process complexity of selectifier, sieve aperture or sieve seam stop up easily, separative efficiency is lower, fault rate is higher, separate different particle of proportion or the relatively poor defective of fiber effects.
