Abstract

The utility model discloses a whirlwind screen, belonging to a screening apparatus for mesh screening solid materials. The utility model is mainly suitable for the screening of solid materials which are provided with adhesiveness, extra-light specific gravity and easy to agglomerate. The utility model is characterized in that a screen body adopts the horizontal cylinder structure, and the interior of the horizontal cylinder is provided with a cylindrical screen mesh. The inlet of the screen body on a main shaft is provided with screw propeller blades, and the interior of the cylinder is fixed with a cylindrical blade cutter shelf. The surface of the cutter shelf is provided with a plurality of sawtooth-shaped blades and cutter-shaped blades. The cylindrical screen mesh and a machine casing are kept at a certain distance. The materials are brought in the screen body through the screw propeller blade first, and then flown toward and permeated through the screen mesh due to the centrifugal force generated from the rotation.

Description

Whirlwind screen
The utility model belongs to the screening plant field with mesh screen screening solid material.Mainly be applicable to adhesive, the easily screening of pressed powder material agglomerating, that the proportion spy is light.
Existing pressed powder Supplying Sieving Mechanism only limits the use of in the screening of drying, good dispersion, as to have certain weight proportion pressed powder material.For adhesive material, in screening process, its powder often is bonded on the mesh or edge, even mesh is blocked, and does not reach screening effect; For easily agglomerating pressed powder material, in screening process, the existing pelletizing of a part obtains disperseing by running foul of each other, but also some contacts with running foul of each other in the vibration of screening, forms new pelletizing, causes screening effect poor; For light specific gravity, the easy powder material that floats, in screening process, because the vibration or the swing of screen cloth, this class powder material is difficult for the contact screen cloth, so screening effect is also poor.
The purpose of this utility model is to provide a kind of adhesive, easy Whirlwind screen of pressed powder material agglomerating, light specific gravity that is specially adapted to sieve.
According to above-mentioned purpose, the utility model has adopted following technical measures:
Structurally, adopt horizontal garden barrel structure, and end sealing, garden cartridge type screen cloth of assembling in the tube of garden; On horizontal main axis,, several pieces screw propulsion blades are housed by garden tube import department; Be on the main shaft in the tube of garden and fix a garden tubular blade knife rest, several pieces and axial consistent sawtooth pattern blade and the cutter type blade of main shaft are equipped with in its surface.Two kinds of blades are from spirality, and angled with main shaft.Cutter type blade had both played the fan blade effect, played net effect clearly again.
The operation principle of this utility model is as follows: when main axis rotation, the material of being sent to by charging aperture rotates formed whirlwind by the propelling of screw propulsion blade and blade and brings in the garden tube of Whirlwind screen, owing to produce centrifugal force during rotation, material is flown to and penetrate screen cloth, for adhesion or agglomerating powder material, constantly cut dispersion by the sawtooth pattern blade, made it net; Simultaneously, cutter type blade and screen cloth inwall produce pressure, force powder to cross net; When the cohesive powders material sieved, in case be bonded on the net, then the hairbrush on the sawtooth pattern blade was sent out the sample effect, made it brush and fell net.
In addition,, make and failed the powder material of net and pass forward vertically, discharge from discharging opening because two kinds of blades form an angle with main shaft, the powder material of screen cloth drop on the bottom of garden tube, discharge by the screenings discharging opening.
The utility model compared with prior art has following advantage:
1. can sieve the powder material of adhesive or easy balling-up or light specific gravity, adapt to wide.
2. because the rotation of main shaft and two kinds of blades, and screen cloth is the garden tubular, and surface area is big, and the touch opportunity of powder material and screen cloth is many, the screening efficiency height.The efficient of the existing screening machine more equal than screen area improves twice.
3. be closed on the structure, preferably to the fine powder that lightweight is easily flown upward.
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Accompanying drawing 1 is the structural representation of the utility model Whirlwind screen.
Accompanying drawing 2 is the A-A profile in the accompanying drawing 1.
Among Fig. 1 and 2,1 is motor, and 2 is decelerator, 3 is main shaft, and 4 is the screw propulsion blade, and 5 is garden cartridge type screen cloth, 6 is cutter type blade, and 7 is the sawtooth pattern blade, and 8 is charging aperture, 9 is control gate, and 10 is the oversize discharging opening, and 11 is the screenings discharging opening, 12 is the casing of garden tube, 13 is garden tubular blade knife rest, and 14 is hairbrush, cramp bar 15.
Found out that by figure garden tubular blade knife rest 13 is fixed on the main shaft 3 by cramp bar 15, several pieces sawtooth pattern blades 7 and cutter type blade 6 all are assemblied on the surface of garden tubular blade knife rest 13; 14 of hairbrush are assemblied between the sawtooth of sawtooth pattern blade 7; Garden cartridge type screen cloth 5 is fixed on the side of casing 12 of garden tube, and keeps certain distances with casing 12; Screw propulsion blade (4) is assemblied in main shaft (3) and goes up the import department of leaning on garden shaft screen body.

Claims (4)
