Detailed description of the invention
Below in conjunction with accompanying drawing, adjustable inclination angle its detailed description of the invention of self-cleaning vibration drum screen, structure, feature and effect thereof that the present invention is proposed are described in detail.
In the adjustable inclination angle self-cleaning vibration drum screen solid simplified schematic diagram shown in Fig. 1, its rotary screen is the cylinder that sieve plate 7 surrounds, and cylinder feed end is eight prismatic, and discharge end is cylindrical shape.The both ends of cylinder are provided with coupled flange, and are respectively connected with an annular dead turn 14 by the securing member being located on flange.Being provided with the outer scraper stent of 8 angle steel shapes on its periphery face discontinuously, its right-angle side parallel with cylinder tangent line is separately fixed on two flanges by securing member, and the right-angle side vertical with cylinder tangent line is connected with outer scraper plate 8 by securing member.Being provided with outside above-mentioned cylinder and contained by cylinder and have two upper and lower guard shields of semi-cylindrical up and down in a small amount of gap with outer scraper plate free end, upper shield 5 opening is located on lower shield 4 opening, and is flexibly connected by connector.Lower shield is located at 4 root post formula shield stand 3 upper ends, and these shield stand lower ends are fixed on the frame-type of underframe on underframe 2.On this, underframe is positioned at cylinder discharge end side and is connected with underframe two column by hinge, this underframe two column lower end is provided with underframe 1 under perpendicular connected frame-type, the other end of this lower underframe and cylinder feed end are provided with two vertical hydraulic cylinders 18, the hydraulic stem upper end of these two vertical hydraulic cylinders and upper underframe hinged 17.Being additionally provided with vertical damping hydraulic cylinder 20 on lower underframe between underframe column and hydraulic cylinder, the piston rod upper end of this damping hydraulic cylinder is also hinged with upper underframe.Being provided with framework shape conveyer bridge 16 between upper and lower underframe, this conveyer bridge is connected on 5 pairs of vertical underframe columns, and one end is positioned at cylinder discharge end, and the other end stretches out underframe, as shown in Figure 3.Two dead turns on above-mentioned cylinder are respectively provided on two pairs of support rollers of cylinder feed end and discharge end, cylinder side is respectively provided at two support rollers 15 of feed end and discharge end, their supporting-roller shaft is connected with same decelerator 21 respectively through shaft coupling and power transmission shaft 13, this decelerator is connected with buncher 19, as shown in Figure 4.Above-mentioned decelerator, buncher and bearing block are each provided on underframe.Being provided with inside strake mechanism on above-mentioned cylinder, as shown in Figure 5 and Figure 6, it has two door font connectors being made up of square steel 9, and their opening is all towards cylinder, and parallel one, two bars of each connector are located in cylinder, and another root is located at outside cylinder.This bar bottom being located at outside cylinder is provided with 2 inside strake bearings 6, and it is connected with upper shield by securing member；And it being located at the bar in cylinder, end is provided with vertical adjustment square steel 12, and this adjustment square steel is provided with setting up and down two strip through-hole, is flexibly connected with press strip one end by securing member.The two of two connectors regulate square steel then by location, press strip 11 two ends corresponding with cylinder sieve plate for length.Being connected with polyurethane inside strake 10 by securing member on press strip, inside strake free end is close to sieve plate.
Before rotary screen work, determining the angle of inclination of rotary screen according to the kind of rubbish material, thus set the initial elongation amount of hydraulic cylinder (18) piston rod, the working method concurrently setting piston rod carries out vibratory cleaning or vibration screening.When rotary screen works, buncher (19) works, cylinder is driven to rotate through decelerator (21), power transmission shaft (13), support roller (15) transmission, rubbish material is poured in cylinder by rotary screen feed end, screening is rotated through cylinder, sifting out to conveyer from sieve aperture less than the material of sieve diameter, remaining rubbish material then falls from rotary screen discharge end.For common rubbish material, rotary screen works a period of time, carries out repeatedly short range reciprocating and stretch in hydraulic cylinder (18) the piston rod short time, and cylinder is fixed periodic vibration cleaning；For adhesion rubbish material, hydraulic cylinder (18) piston rod back and forth becomes stroke motion continuously, produces self excitation force, makes cylinder in periodic oscillations upper and lower while own axis, and the adhesion material block in cylinder realizes vibrator screening.Along with stretching of hydraulic cylinder (18) piston rod, damped cylinder (20) passively works, and keeps rotary screen easy motion.It is combined with the difference at rotary screen angle of inclination, the speed also respective change of buncher (19).When inclination angle is relatively large, motor speed slows down, it is to avoid rubbish material has little time screening and is directly slipped to discharge bucket owing to speed high inclination-angle is big.In rotary screen work process, rubbish very likely adheres to lower shield (4) after falling from sieve aperture, and accumulation too much will affect the rotation of cylinder.Outer scraper plate (8) rotates along with the rotation of cylinder in the present invention, constantly cleans the rubbish being attached on lower shield (4) with water；Inside strake is fixed on upper shield (5), with cylinder relative motion, the rubbish of rolling barrel inwall attachment, it is to avoid the blocking of sieve aperture.The real-time cleaning effect of inside and outside scraper plate does not need extra power and carries out with rotary screen work simultaneously, time saving and energy saving.
These are only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope of present disclosure; the replacement equivalent according to technical scheme and design concept thereof or change, all should be encompassed within protection scope of the present invention.
