Abstract
The utility model relates to the field of mechanical devices, in particular to a rotary screen. The rotary screen comprises a feed port (1), a discharge port (2), a roller (3), a rotating shaft (4), a drive-transmission mechanism (5), bearing supports (6), screen holes (7), a rolling device (8) and a blade (9). By the adoption of the rotary screen, materials are prevented from blocking the screen holes, discharging is automatic, the screening effect is improved, and operation is easy.
Description
Technical field
The utility model relates to plant equipment field, relates in particular to cylinder screen(ing) machine.
Background technology
Coal charge, in the process of screening, tends to stop up sieve aperture, causes screen(ing) machine screening effeciency to decline.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide cylinder screen(ing) machine, can prevent feed blocking sieve aperture, improves the efficiency of screening, simple to operate.
The technical solution of the utility model is: a kind of cylinder screen(ing) machine, comprise the cylinder of an end opening, other end sealing, described cylinder is provided with sieve aperture, be arranged on the rolling device of described cylinder one end, one end around described cylinder install, the other end is supported on the ground support of bearing, driving-transmission mechanism, the rotating shaft being connected with described driving-transmission mechanism, be arranged on the spiral vane in described rotating shaft, one end near described rolling device on described cylinder wall is provided with charging aperture, and described charging aperture place is provided with feeding gate.
Described cylinder does not have described sieve aperture near the wall at two ends.
The inside of described cylinder is stretched in described rotating shaft, and does not contact with one end of described cylinder.
Described spiral vane does not contact with described inner wall of rotary drum.
The beneficial effects of the utility model are: can prevent feed blocking sieve aperture, improve the efficiency of screening, and easy to operate.
Brief description of the drawings
Fig. 1 is the cylinder cross-sectional view of the utility model embodiment.
Fig. 2 is the structural representation of the cylinder exhaust end of the utility model embodiment.
In figure, 1. charging aperture, 2. discharge gate, 3. cylinder, 4. rotating shaft, 5. driving-transmission mechanism, the 6. support of bearing, 7. sieve aperture, 8. rolling device, 9. spiral vane, 10. feeding gate.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is explained.
Referring to Fig. 1 and Fig. 2, cylinder screen(ing) machine of the present utility model, is mainly made up of cylinder 3, rolling device 8, charging aperture 1, discharge gate 2, driving-transmission mechanism 5, the support of bearing 6, sieve aperture 7, rolling device 8, spiral vane 9, feeding gate 10.
Cylinder 3 one end are provided with rolling device 8, and the other end is exhaust end, are provided with discharge gate 2.Rolling device 8 is connected with power set, for the rolling of cylinder 3 provides power.
Cylinder 3 is provided with sieve aperture 7, and sieve aperture 7 is for discharging satisfactory coal charge.Near the two ends of cylinder 3 around the support of bearing 6 is installed, for back-up roller 3 and make it do rolling movement.Cylinder 3 upper bearing (metal) supports 6 around position there is no sieve aperture 7, to protect the support of bearing 6.
Driving-transmission mechanism 5 is arranged on the outside of cylinder 3, for the rotation of rotating shaft 4 provides driving force.The inside of cylinder 3 is stretched in rotating shaft 4, is installed with spiral vane 9 on it.When spiral vane 9 rotates along with rotating shaft 4, the coal charge that size can be greater than to sieve aperture 7 is taken cylinder 3 out of.Spiral vane 9 does not contact with cylinder 3, prevents from damaging cylinder 3.The opposite direction of the direction that rotating shaft 4 is rotated and cylinder 3 rollings.
Workflow: pour coal charge into cylinder 3 from charging aperture 1, then close feeding gate 10, then start power supply, make rolling device 8 drive cylinder 3 to start rotation, meanwhile, open the power supply of driving-transmission mechanism 5, make rotating shaft 4 drive spiral vane 9 to start rotation.In the process of work, the rotation of cylinder 3 evenly separates coal charge, makes coal charge up to specification fall into the loading head of below through sieve aperture 7.Meanwhile, spiral vane 9 applies power to coal in the process of rolling, it is more easily dropped by sieve aperture 7, and can not stop up sieve aperture 7.Under blade 9 effects, the chute of below can discharge and fall into from discharging opening 2 to the coal charge that does not see through sieve aperture 7.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
