The specific embodiment
For understanding better the present invention, below in conjunction with drawings and Examples, the invention will be further described.
With reference to Fig. 1-3, the present invention is a kind of subset of the rotary screen for the material screening fragmentation, can adapt to material fragmentation and screening under many environment.Mainly by housing 5, screen drum, the bracing or strutting arrangement 15 for screen drum is fixed, clearing apparatus 18 and the compositions such as transmission device, drawing mechanism 8 in housing 5; It is characterized in that: described screen drum adopts the lateral inclination mode to install, cylindrical shell consists of the main beam in frame between front end slip ring 3, rear end slip ring 7 and two slip rings, main beam in frame is that cross section is polygonal cylindrical shell framework, on main beam in frame along the cylindrical shell direction fixedly the sieve plate of polylith different pore size form the polygon tubular space of a sealing; Sieve plate is divided into scalping plate 4 and thin sieve plate 6 by entrance point to the port of export; Sieve plate is arranged on main beam in frame by press strip, between sieve plate and main beam in frame, fills sealing strip, and on main beam in frame, also assembling is for the broken blade 19 of broken material, and the sieve plate outside also is provided with the round brush shape clearing apparatus 18 contacted with sieve plate.
Front end slip ring 3 belows also correspondence arrange position-limited wheel 17, and 3 contacts of position-limited wheel 17 and front end slip ring are also followed together with slip ring and rotated when slip ring rotate, thereby limit the screen drum cylindrical shell, move downward.
Described main beam in frame is that angle steel forms, and is specially the inboard head and the tail of two slip rings and connects uniform angle steel, and angle steel is divided into polygon by each slip ring, and reinforcement is arranged between angle steel, and sieve plate is arranged on angle steel by press strip, between sieve plate and angle steel, fills sealing strip.This structure has guaranteed installation accuracy, and stability of rotation does not vibrate, and during maintenance, sieve plate can directly be changed from the outside.
Transmission device is comprised of variable-frequency motor 1, support roller 16 and power transmission shaft 14.Front end slip ring 3 and rear end slip ring 7 belows arrange support roller 16, and support roller 16 forms respectively two pairs of friction pulley transmissions with front end slip ring 3 and rear end slip ring 7.Support roller 16 cylindricals adopt the rubber-wrapping structure with adaptivity, improve the coefficient of friction of support roller and slip ring, increase driving force, are convenient to adjust.Power transmission shaft 14 is positioned at screen drum below parallel with the screen drum center line, at the two ends of power transmission shaft 14, fixes respectively described support roller 16.Power transmission shaft 14 adopts variable-frequency motor 1 to drive, and rotating speed is stepless adjustable.Power transmission shaft, at the homonymy (bottom) of rotary screen subset, is respectively and adopts bearing or segmentation axle according to different size equipment power transmission shaft, in the middle of the segmentation axle, with shaft coupling, connects.Active roller station is installed on power transmission shaft, and cylindrical shell supports by two passive support rollers of two active roller stations on power transmission shaft and the power transmission shaft other end.Support roller and the cylindrical shell slip ring friction drive wheel that partners carries out transmission.
Described bracing or strutting arrangement 15 is the bracing frame be connected with the basis, ground, and the angle of bracing or strutting arrangement 15 can be adjusted by regulating oil cylinder 11.Make the duty of rotary screen subset to adjust in the scope of 3 ° ~ 8 °, alignment pin is locked, safe and reliable, is equipped with the cylindrical shell of two gear wheel position rotating screening plants at the front end of bracing or strutting arrangement.
Drawing mechanism 8 comprises the dregs outlet 13 that bottom is corresponding with scalping plate 4, the finished product material outlet 12 corresponding with thin sieve plate 6, and the oversize of barrel tip outlet 10.Drawing mechanism 8 places also are provided with the banister 9 for maintenance.
Operation principle: when variable-frequency motor 1 drives the power transmission shaft rotation, support roller 16 just will drive the slip ring rotation, thereby drive the cylindrical shell rotation, material enters in cylindrical shell by motion device 2, under the drive of cylindrical shell, to be brought to high point and then fall again low spot, make tumbling motion, the coarse fodder of large particle diameter is sifted out in dregs outlet 13, the material that is less than hole diameter of sieve (perforated) plate just exports 12 by finished product material and discharges the rotary screen subset, because adopting, cylindrical shell tilts to install, material can travel forward on rolling limit, limit, total length by the rotary screen subset, until defective material is discharged from oversize outlet 10.
