Description
Technical field
The utility model is related to materials to sort field, particularly, is related to the sieve plate and rotary screen of a kind of rotary screen.
Background technology
During refuse classification screening, rotary screen is by the sieving machine of wide selection.Roller sieve structure includes sieve plate
With screen drum, sieve plate is made by certain thickness steel plate, trepanning and whole plate is made arc, then sieve plate is fixed on screen drum on the steel plate
On.Rotary screen is classified rubbish according to grain size using the tubular screen drum for making rotary motion, grain size be less than sieve pore rubbish from
Sieve pore is fallen, and the rubbish more than sieve pore passes through from sieve pore.However, due to containing a large amount of twister in rubbish, in rotary screen
In motion process, twister easily passes around from the sieve pore of sieve plate and crosses the arrival sieve plate back side in rubbish, then is sieved by others
Sieve pore blockade such as Fig. 1 is caused so as to tangled up and knotted in hole.
It is currently used for reducing the rotary screen design of tangled up and knotted, such as the Chinese invention of Patent No. 201310101859.7
In patent, the sieve pore of sieve plate is arranged in rows, and antiwind lath is set between two rows of sieve pores adjacent along ring circumferential direction, to prevent item
Winding and knotting of the shape material at the two rows of sieve pores adjacent with antiwind lath.
But this design is due between antiwind lath is arranged on adjacent two rows of sieve pores, being only capable of preventing adjacent two rows of sieves
Winding and knotting at hole, and still remained between the two neighboring sieve pore in same row's sieve pore because twister passes through one of
Sieve pore and by adjacent sieve pore and tangled up and knotted the problem of, the sieve pore in same row is still easy to block.
Utility model content
The utility model provides the sieve plate and rotary screen of a kind of rotary screen, to solve in rotary screen sieve pore because twister twines
The technical issues of being blocked around knotting.

Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the application can phase
Mutually combination.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
With reference to Fig. 2 to Fig. 5, the preferred embodiment of the utility model provides a kind of sieve plate of rotary screen, including being equipped with sieve
The plate body 1 in hole 2, plate body 1 have opposite medial surface 10, lateral surface 11, be provided on lateral surface 11 both ends open and with sieve pore 2
The antiwind cylinder 3 of connection, antiwind cylinder 3 is around the outer periphery of sieve pore 2.The utility model passes through the lateral surface 11 in sieve plate
On add both ends open and the antiwind cylinder 3 connected with sieve pore 2, twister 4 needs to arrive by sieve pore 2 and antiwind cylinder 3
Up to the lateral surface 11 of sieve plate, twister 4 is increased by stroke, and twister 4 is not easy to pass around sieve pore 2 back and forth, thus can reduce
The probability that the winding of sieve pore 2 blocks；For antiwind cylinder 3 around 2 outer periphery of sieve pore, the outside of sieve pore 2 is comprehensive by antiwind cylinder 3
It surrounds, thus twister 4 is all increased from which direction by the stroke of sieve pore 2, be further reduced sieve pore 2 and is wound
The probability that the winding of object 4 blocks increases the working efficiency and service life of sieve plate and rotary screen.
As shown in Figure 2, in this preferred embodiment, multiple circular sieve pores 2 are provided on plate body 1, multiple sieve pores 2 are in plate body
In regularly arranged on 1.The outer periphery of each sieve pore 2 is both provided with antiwind cylinder 3.So ensure around each sieve pore 2
All by antiwind with surrounding, protection is all formed between the adjacent sieve pore 2 of any two so that each sieve pore 2 be not easy by
4 tangled up and knotted of twister and block.
With reference to Fig. 3 to Fig. 5, the barrel 30 and plate body 1 of antiwind cylinder 3 are not parallel.In this preferred embodiment, antiwind cylinder 3
Barrel 30 perpendicular to plate body 1, thus barrel 30 is used to increase the effective distance i.e. actual height of barrel 30 of 4 stroke of twister
T can utmostly play the function of barrel 30, while save material.Certainly, in other embodiments, barrel 30 can also incline
Tiltedly set and have between plate body 1 angle of non-90 degree.
Barrel 30 is more than the thickness of plate body 1 from 11 outwardly extending height t of lateral surface, and 30 height t of barrel can be prevented too small
And it is allowed to that the function of increasing by 4 stroke of twister can not be played.The height t of barrel 30 determines according to the rotational speed that actual drum is sieved
It is fixed.Specifically, the rotational speed of rotary screen is slower, and setting height t is bigger needed for barrel 30.
In this preferred embodiment, antiwind cylinder 3 is cylinder.The internal diameter of antiwind cylinder 3 is equal with the internal diameter of sieve pore 2.Circle
The winding cylinder of putting of cylindricality is corresponded with 2 shape and size of sieve pore and position, it is ensured that the function of antiwind cylinder 3, while conveniently
Machine-shaping, shape neat appearance.
In this preferred embodiment, antiwind cylinder 3 is equally made of steel plate, and antiwind cylinder 3 is fixedly welded on lateral surface 11
Upper corresponding position.So facilitate the processing and fixation of antiwind cylinder 3.
It is of course also possible to use the mode that antiwind cylinder 3 extends outward from 1 one of plate body.It for example, can be by plate body 1
The upper material formed at 2 position of sieve pore directly forms antiwind cylinder 3 using deep-drawing technique.
In other embodiments, sieve pore 2 can also be non-circular, such as rectangle or other irregular shapes.Correspondingly,
The shape of antiwind cylinder 3 also can be corresponding with the shape of sieve pore 2.
Another aspect according to the present utility model additionally provides a kind of rotary screen, including screen drum, is equipped on screen drum above-mentioned
Sieve plate.
The rotary screen of the utility model on the lateral surface 11 of sieve plate due to by adding both ends open and being connected with sieve pore 2
Antiwind cylinder 3, twister 4 needs to get to the lateral surface 11 of sieve plate by sieve pore 2 and antiwind cylinder 3.The outside of sieve pore 2
It is surrounded, thus twister 4 is all increased from which direction by the stroke of sieve pore 2, works as winding by antiwind cylinder 3 is comprehensive
When the leading portion of object 4 reaches the lateral surface 11 of sieve plate not yet, rotary screen has been rotated into top blanking position, twister 4 then by
It leaves, tangled up and knotted process is interrupted, and so as to substantially reduce the probability that the winding of sieve pore 2 blocks, increases the work effect of rotary screen
Rate and service life.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
