Description
Technical field
The present invention discloses a kind of sieve, more particularly, to a kind of round swinging screen.
Background technique
Existing circle swinging screen is driven by vibration excitor and is swung by feed inlet, screen frame, sieve, identical material discharge port, and material exists
Motion mode as sieved manually on sieve, thus reach screening effect, round swinging screen at least two layers of screen frame, every layer of screen frame
Side is provided with an oversize discharge port, and material falls into sieve through feed inlet, and material is sieved by sieve under vibration excitor drive,
Turn bulky grain and be transported to exit, this time process repeats between each layer there, carries out classification processing screening to material, insufficient
Place is that screening precision can not get both with screening yield, and when largely sieve, screening precision is poor, Bu Nengman
Requirement of the sufficient enterprise to yield and precision.Round swinging screen is used to screening materials carrying, by starting vibrating motor and passes through eccentric block
Completion is waved and is vibrated, so that material is sieved, the filament on sieve can be damaged and can not be screened over time, is just needed
Replacement sieve is shut down, since existing sieve is made of upper and lower net pressing ring, the surface of net pressing ring is plane, in replacement sieve
Shi Buneng effectively by sieve screen tightening, makes sieve out-of-flatness, to reduce the service life of sieve.
Invention task
The task of the present invention is proposing that one kind improves screening precision yield on not changing screening plant main body, and efficiently more
Good sieve, and can a kind of effectively circle of tightening screen net wave sieve structure.
The task of the present invention is what is completed in this way, it is characterised in that：The middle part of existing screen frame is arranged in double screening frame
Position, and double sieve oversize discharge port and another double sieve oversize discharge port are symmetrically arranged on existing screen frame, it is described double
Times screen frame is machined with a mixture secondary feeds mouth, and for the sieve of the double screen frame centered on circle, slant setting has one
Material blanking slide carriage, stretching structure include upper pressure network circle and push net circle, and the upper pressure network circle is machined with annular protrusion, under described
It is machined with annular groove on pressure network circle, and pushes to put to have sieve and then upper pressure network circle is corresponded to pushing net circle in net circle and falls pressure
Firmly sieve, and compressed sieve with pressure network bolt and lock nut, it is arranged at intervals on the upper and lower net circle ring to tooth hole, and
It is fastened again with bolt.The shape of annular groove on the upper pressure network circle is to constitute primary and secondary buckle structure in V-shape, further
It says, and the annular protrusion of upper pressure network circle setting is that face is arranged with the groove pushed in net circle, on the ring of the upper and lower pressure network circle
It is evenly arranged with the screw hole passed through for pressure network bolt.And what is be arranged on upper and lower pressure network circle is 20 centimetres to tooth hole separation distance.
The present invention has the following effects that the technical program is structurally reasonable, and using effect is good, has both been able to satisfy the need of screening efficiency
It wants, while the precision sieved is improved, and can be completed the double treating capacity of general screen frame, can be made well by sieve screen tightening
Sieve is smooth in conjunction with rack, and sieve will not drop when use, to extend the service life of sieve.

Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Specific embodiment is as shown in Figure 1, the upper cover center of round swinging screen is feed inlet 4, in the two sides of feed inlet difference
It is observation window 3 and another observation window 5, screen frame side is oversize discharge port 2, and motor 9 is fixed on pedestal 8 between bottom frame
It is supported by rubber legs 7, is that the prior art is no longer described in detail above, the screen frame of the technical program is double screening frame 6, described double
The intermediate position of existing screen frame is arranged in screening frame, and be symmetrically arranged on existing screen frame double sieve oversize discharge port 10 with separately
Object discharge port 11 on one double screen frame, the double screen frame are machined with a mixture secondary feeds mouth 13, the double sieve
For the sieve of frame centered on circle, slant setting has a material blanking slide carriage 12.
Upper one layer of screen frame of double screening frame requires to be not provided with oversize discharge port.
The double oversize discharge port 10 and another double oversize discharge port 11 are symmetricly set on screen frame.
Stretching structure on screen frame includes upper pressure network circle 15 and pushes net circle 17, and the upper pressure network circle is machined with annular protrusion
19, annular groove 20 is machined in the pushing net circle, and push put in net circle have sieve then will upper pressure network circle it is corresponding under
Pressure network circle, which is fallen, pushes down sieve, and is compressed sieve with pressure network bolt 16 and locking nut 18, is spaced on the upper and lower net circle ring
It is provided with to tooth hole, blending bolt fastens again.
The shape of annular groove on the upper pressure network circle is to constitute primary and secondary buckle structure in V-shape, furtherly, and on
The annular protrusion of pressure network circle setting is that face is arranged with the groove pushed in net circle, is uniformly set on the ring of the upper and lower pressure network circle
It is equipped with the screw hole passed through for pressure network bolt.
In order to make the stronger of sieve screen tightening, the generation of anti-falling stop net in use, and set on upper and lower pressure network circle
Setting is 20 centimetres to tooth hole separation distance.
It is to sum up known, the technical program be by double screen frame 6, double oversize discharge port 10 and 11, material blanking slide carriage
12, mixture secondary feeds mouth 13 overcomes prior art screening precision and sieves the problem that powder yield can not get both.This technology side
Case is overcome by upper pressure network circle 15, pushing net circle 16, annular protrusion 19, annular groove 20, pressure network bolt 16, locking nut 18
The inconvenient defect with sieve out-of-flatness after replacement of prior art sieve replacement.
When work, after material flows into the sieve of double screen frame by upper one layer of sieve, the material that a part is sieved is along screen frame
Object blanking slide carriage is discharged along oversize discharge port, and another part material enters lower layer's screening along mixture secondary feeds mouth,
Oversize can not only improve sieve so that completing a screen frame completes double treating capacity along another discharge port discharge of oversize
Divide precision, while also meeting screening efficiency.When replacing sieve, sieve, which is laid in, to be pushed in net circle, will be pushed net circle and is buckled in down
On pressure network circle, protrusion and groove form snap fastener structure, with hold-down bolt by nut fastening, then with bolt by upper and lower pressing ring
Set on ring to being fixed after the alignment of tooth hole, be that sieve can be smooth in conjunction with rack, and sieve screen tightening degree is secured, thus
Extend the service life of sieve.
In the present invention unless specifically defined or limited otherwise, the arts such as term " installation ", " connected ", " connection ", " fixation "
Language shall be understood in a broad sense, for example, it may be fixedly connected, may be a detachable connection or integrally connected, can be two members
Connection inside part.For those skilled in the art, above-mentioned term can be understood of the invention as the case may be
Concrete meaning.
