Abstract
The utility model discloses a sieve body structure for a trommel sieve. The sieve body comprises a feeding-end shell, a wheel belt arranged on the feeding-end shell, a discharging-end shell, a wheel belt arranged on the discharging-end shell, a longitudinal supporter provided with projections at the inner side and arranged between the feeding-end shell and the discharging-end shell, a circular supporter arranged at the outer side of the longitudinal supporter, and a plurality of detachable sieve plates arranged at the outer side of the framework consisting of the longitudinal supporter and the circular supporter. The structure forms projections on the inner wall of the shell which is segmented in the sieve and can play the role of throwing materials, thereby not only increasing the sieving efficiency, but also ensuring that the replacement of the sieve plate is convenient.
Description
Affiliated technical field
The utility model relates to the solid material screening installation, especially relates to a kind of sieve nest structure of screening installation rotary screen.
Background technology
At present, the method for urban garbage disposal has a variety of, but almost every kind of processing method all needs through refuse classification, and refuse classification is an important procedure of garbage disposal process, and rotary screen then is the key equipment in the refuse classification.In existing rotary screen, the structure of its sieve nest all is the inboard of sieve plate at framework, such structure is made of the cylinder inboard wall of screening section fully sieve plate, inwall is smooth, does not have projection, can not play the effect of shedding to the material that passes through, thereby screening efficiency is lower, and change sieve plate and must enter inner barrel, because equipment operation rear cylinder body internal environment is abominable, like this to the cleaning of equipment with safeguard and all brought inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary screen sieve nest structure, to solve the shortcoming and defect of prior art.This sieve nest structure is that its sieve plate is fixed on the framework outside of being made up of longitudinal bracing, hoop support, such structure can not only externally be changed sieve plate very easily, and longitudinal bracing makes the cylinder inboard wall of screening section form projection, can play the effect of shedding to material, make it improve screening efficiency
The technical scheme that its technical problem that solves the utility model adopts is: this sieve nest comprises a feed end cylindrical shell; One is located at the wheel band on the feed end cylindrical shell; One discharge end cylindrical shell; One is located at the wheel band on the discharge end cylindrical shell; There is protruding longitudinal bracing the inboard that is located between the charging and discharging end cylindrical shell; The hoop that is located at the longitudinal bracing outside supports; Be located at longitudinal bracing and hoop and support several sieve plates that have demountable structure on the outside of forming framework.
The wheel band is the box Welding Structure on the charging and discharging end cylindrical shell, and inner barrel is provided with the spiral stock guide of certain angle.Longitudinal bracing is close to the inside of cylindrical shell, and support protrusion can be a shaped steel, also can be other structure that has projection, and quantity is 6～10, is uniformly distributed along the circumference.Hoop supports and arranges with certain spacing along the sieve nest length direction.The sieve plate that has certain pore size is connected on the framework of longitudinal bracing and hoop support composition with demountable structure.Demountable structure can be that bolt connects, and also can be other similar structures, and sieve plate can be the punching steel plate, also can be the welding steel mesh.
The beneficial effects of the utility model are to adopt this rotary screen structure, because there is projection the longitudinal bracing inboard, make material when passing through, material longitudinally support protrusion moves up, material is shed after moving to certain position, improves screening efficiency, simultaneously because sieve plate is located at the outside of support, externally can change easily, increase human oriented design by demountable structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1 along the A-A line;
The specific embodiment
Fig. 1-Fig. 2 shows the utility model rotary screen sieve nest structure, this sieve nest comprises feed end cylindrical shell 1, the wheel that is located on the feed end cylindrical shell is with 2, be located at the spiral stock guide 3 of feed end cylinder inboard wall, discharge end cylindrical shell 9, the wheel that is located on the discharge end cylindrical shell is with 8, be located at the spiral stock guide 7 of discharge end cylinder inboard wall, the longitudinal bracing 6 that connects charging and discharging end cylindrical shell, the hoop of fixed longitudinal supporting 6 supports 5, is fixed on longitudinal bracing 6 and hoop and supports the sieve plate 4 that has demountable structure on the 5 framework outsides of forming.During work, entered in the tube from the cylindrical shell feed end by the sieve material, because the rotation of sieve nest, material slides along the sieve nest inwall because there is projection the longitudinal bracing inboard, make material longitudinally support protrusion move up, material is shed after moving to certain position, in this process, particulate (less than sieve diameter) material constantly falls by the sieve aperture on the working surface, and thick material (greater than sieve diameter) is then discharged from the discharge end of sieve nest.
Behind the work certain hour, when sieve plate needs replacing owing to wear and tear, the burn into overload is damaged etc., support the framework outside of forming, externally can change easily by demountable structure owing to sieve plate is located at by longitudinal bracing and hoop.
