The rotary screen comprises a tapered screen drum (1), a transmission shaft (2), a shell (4) and a pillow block bearing (5), wherein the tapered screen drum (1) is arranged in the shell (4) and is fixedly connected with the transmission shaft (2); the transmission shaft (2) is supported by the pillow block bearing (5) arranged on the shell (4); one end of the tapered screen drum (1) is provided with a feeding hole, and the other end of the tapered screen drum (1) is provided with a slag outlet; the wall of the tapered screen drum (1) is provided with meshes (11); the apertures of the meshes (11) are gradually reduced along the direction from the feeding hole to the slag outlet. The rotary screen can be used for rapidly screening the material, thus improving the screening efficiency.
Description
Technical field
The utility model relates to a kind of rotary screen, relates in particular to a kind of rotary screen of conical sieve tube.
Background technology
Used rotary screen sieve opening size is all identical, when material is more, can not fast and effeciently to material, sieve, and causes material screening efficiency lower.And the mobility of material in rotary screen is also poor, when material reduces gradually through screening, because foreign material are easily embedded in sieve aperture, cause foreign material to be discharged not smooth, also affect the screening effect of material simultaneously, easily there is putty phenomenon.
Utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the lower and easy putty of current rotary screen screening efficiency.
In order to solve the problems of the technologies described above, the utility model provides a kind of rotary screen of conical sieve tube, and this rotary screen comprises conical sieve tube (1), power transmission shaft (2), housing (4) and rolling bearing units (5); Described conical sieve tube (1) is positioned at described housing (4) inside, is fixedly connected with described power transmission shaft (2); Described power transmission shaft (2) supports by the described rolling bearing units (5) that are arranged on described housing (4); One end of described conical sieve tube (1) is charging aperture, and the other end is slag notch; On the wall of described conical sieve tube (1), be provided with sieve aperture (11), the aperture of described sieve aperture (11) dwindles gradually on the direction from described charging aperture to described slag notch.
Preferably, described conical sieve tube (1) osculum end is described charging aperture, and big opening end is described slag notch.
Preferably, described housing (4) is formed with discharging opening (41) in the below of described conical sieve tube (1).
Preferably, described housing (4) is formed with slag-drip opening (42) below described slag notch.
Preferably, described conical sieve tube (1) is fixedly connected with described power transmission shaft (2) by inner brace summer (3).
Compared with prior art, the application's embodiment can sieve material rapidly, has improved screening efficiency.The application's embodiment to material after screening, the remaining material that contains more foreign material during through the less part of sieve aperture, can avoid foreign material to be embedded in hole, can also prevent the generation of the phenomenon of putty.
Accompanying drawing explanation
Fig. 1 is the organigram of rotary screen of the conical sieve tube of the embodiment of the present application.
The specific embodiment
Below with reference to drawings and Examples, describe embodiment of the present utility model in detail, to the utility model, how application technology means solve technical problem whereby, and the implementation procedure of reaching technique effect can fully understand and implement according to this.Each feature in the embodiment of the present application and embodiment, the mutually combining under prerequisite of not conflicting mutually, all within protection domain of the present utility model.
As shown in Figure 1, the rotary screen of the conical sieve tube of the embodiment of the present application mainly comprises conical sieve tube 1, power transmission shaft 2, brace summer 3, housing 4 and rolling bearing units 5 etc.Conical sieve tube 1 is positioned at housing 4 inside, by inner brace summer 3, is fixedly connected with power transmission shaft 2, with the rotation of power transmission shaft 2, rotates.
One end of conical sieve tube is charging aperture, and the other end is slag notch.In the application's embodiment, conical sieve tube 1 osculum end is charging aperture, and big opening end is slag notch.On the wall of conical sieve tube 1, be provided with sieve aperture 11.On the direction from described charging aperture to described slag notch, the aperture of sieve aperture 11 dwindles gradually.
Housing 4, below conical sieve tube 1, is formed with discharging opening 41; Below slag notch, be formed with slag-drip opening 42.Material enters into the charging aperture of conical sieve tube 1 from collecting mouthful 91 grades.
In the application's embodiment, power transmission shaft 2 supports by being arranged on the rolling bearing units 5 at housing 4 two ends, is subject to the driving of drive unit 92, and drives conical sieve tube 1 to rotate.Rolling bearing units 5 are arranged on housing 4.
In the application's embodiment, by 1 pair of material of conical sieve tube, sieve.Sieve aperture 11 on screen drum varies, and according to diminishing gradually towards slag-drip opening 42 directions from charging aperture.This design is screening materials carrying rapidly, and the macropore by useful material by leading portion sieves rapidly, and along with the rotation of screen drum, material can constantly drop down onto discharging opening 41 by sieve aperture 11 simultaneously.
In the application's embodiment, the material not sifting out by sieve aperture 11 can move to slag notch along skew wall.In the process to slag notch motion, can constantly sieve by the sieve aperture 11 diminishing successively.By this process, material can carry out further meticulous screening.
After the screening of the sieve aperture 11 of process leading portion larger aperture, the impurity in material can be many, large to the comparison of resistance of slag-drip opening 42 motions, may occur halfway the situations such as obstruction.The application's embodiment utilizes the sieve aperture 11 constantly dwindling and the screen drum diameter continuing to increase, not only can reduce the resistance of material operation, and by increasing the diameter of screen drum, the quantity of little sieve aperture 11 is increased, guarantee to a certain extent effective sieving area, improved the efficiency of material screening.
In the application's embodiment, power transmission shaft 2 connects into an integral body by brace summer 3 by power transmission shaft 2 and conical sieve tube 1, like this by drive unit 92 by transmission of power to power transmission shaft 2, thereby drive screen drum to be rotated.
Although the disclosed embodiment of the utility model as above, the embodiment that described content only adopts for ease of understanding the utility model, not in order to limit the utility model.Those of skill in the art under any the utility model; do not departing under the prerequisite of the disclosed spirit and scope of the utility model; can in the form of implementing and details, carry out any modification and variation; but scope of patent protection of the present utility model, still must be as the criterion with the scope that appending claims was defined.
