Described transmission device is by being connected between reducing motor and bearing block, chain, sprocket wheel, power transmission shaft and sieve axle.
The present invention has the following advantages:
(1) screening efficiency is high: the height of screening efficiency depends on the size of sieve seam area, roller picker was 300mm by 10 diameters in the past, length is 1000mm, roller bearing is laterally arranged into compass screen surface, and the sieve gap between roller bearing and roller bearing is that the area that these several seams of 13mm are added up is exactly the effective sifting area of this roller picker.Grating sieve axle is established: every grating diameter 10mm, and every sieve gap is 13mm, and sieve shaft diameter is similarly 300mm, and length is 1000mm, 10, sieve axle.A same area is the compass screen surface of 3 square metres, and the effective sifting area of roller picker was 0.117m in the past
2.And the effective sifting area of grating sieve axle compass screen surface is 2.587 m
2, result of calculation proof coal stitches area with the sieve of the screen open ratio of roller picker roller picker in the past and has improved more than 22 times, and efficiency has also improved 22 times simultaneously.
(2) more energy-conservation: coal with in the sieve axle of roller picker all without central shaft, than roller picker in the past aspect sieve axle weight light half.Its two, sieve seam area is large, required sieve axle radical is few, power of motor also reduces thereupon.If: feed size 300mm; Discharging-material size 30mm; If supplied materials is 1000t/h; In material, qualified particle diameter accounts for 65%; Roller bearing is 8.Calculate gained, minus mesh is 650t/h; Entering disintegrating machine material is 350t/h.Roller picker screening efficiency was 8% in the past, adopted a motor on every roller bearing, and totally 8 2.2kw are total to 17.6kw.And coal is 95% by roller picker screening efficiency, totally 2 motors are total to 6.2kw.Coal is that roller picker sieved 2/10ths of axle in the past by the grating sieve axle weight of roller picker, therefore motor load is lower.Result of calculation proof adopts coal to compare one day energy-conservation 273kw of roller picker in the past with roller picker.For follow-up equipment disintegrating machine: 900t/h disintegrating machine power is 6000v, 560kw; And 350 tons of motor of crusher power are 380v, 185kw; Adopt the energy-conservation 375kw of disintegrating machine per hour after roller picker for coal.Whole sieve breaks one day energy-conservation 9273kw of system.1 year energy-conservation 3384654 kw.
(3) choke preventing function: one, compass screen surface are anti-blocking is that velocity of rotation by compass screen surface is greater than supplied materials speed and carrys out real compass screen surface choke preventing function.
Its two, anti-blocking in rotary screen axle is to stitch to realize by being the sieve of trapezoid sieve seam, when being less than the coal of trapezoid sieve seam and having clamp-oned up-narrow and down-wide trapezoid sieve seam, coal is discharged by centrifugal force and Action of Gravity Field in hollow sieve axle voluntarily from sieve axle.Three, the way of employing activity grating in grating sieve axle, when movable grating gravitate goes to upper end grating because of coal in the above pressure and the movable grating of Action of Gravity Field fall with other grating between gapped consistent, when going to lower end, movable grating is subject to the effect of gravity and centrifugal force, sieve seam amplifies automatically, the coal in hollow sieve axle can be discharged.Thereby the compass screen surface of realizing is chute blockage charcoal not, in sieve axle, screening efficiency is not guaranteed, greatly promoted to the function of chute blockage charcoal, particle diameter yet.
(4) anti-impact force function: when large-block material has carried out shock-diffusion cloth for the first time when charging aperture drops to wear-resistant cloth flitch, then material is fallen and carried out shock-diffusion cloth for the second time on rotary screen axle.Rotary screen axle adopts two kinds of techniques to make, and the first technique is the seamless steel pipe that adopts wall thickness, and sieve seam is shaped as rectangular slotted hole; The second technique is to adopt sieve plate circle to become sieve axle, and sieve seam shape presents trapezoidal slotted hole.Rotary screen axial wood matter is selected the strong wear-resistant material of shock resistance.
(5) cloth function: the present invention adopts distributing mode three times: cloth drops to wear-resistant cloth flitch for being current column when coal from feeding mouth for the first time, and current shape coal has spread cloth function for the first time immediately.Cloth is coal while falling from wear-resistant cloth flitch for the second time, has dropped to again on rotary screen axle and has spread cloth, completes cloth function for the second time.When coal completes cloth function for the third time when compass screen surface is wavy conveying.The more even screening efficiency of cloth is higher, more easily except ironware, just more favourable to follow-up disintegrating machine operation.
(6) parts replacement: one, wear-resistant cloth flitch need to change wear-resistant cloth flitch after washing away, wear and tear when long-term coal falling.Wear-resistant cloth flitch of the present invention can easily be extracted replacing out.Its principle is the serrate slot that drapery panel support and wear-resistant cloth flitch one end have been designed to intersect interlock, and the wear-resistant cloth flitch other end be designed to can drawing structure, when changing arc liner plate, only need arc liner plate be pulled out from chassis end.
(7) deferrization functional: after the even cloth of material is opened, the thinner ironware of the bed of material is just more easily exposed to material surface, and when the ironware in material is delivered to tramp iron separator lower end, tramp iron separator will pick up the ironware in material immediately, has reached the object of deironing.
(8) sieve axle is all without main shaft: in the sieve axle that drive flange sheet is in the past superimposed as, all have main shaft, thereby such design exists because of crushing function material, to be clamp-oned by force in sieve axle sieve seam sieve axle is filled and become a solid roller bearing when operation, and the present invention is designed to hollow sieve axle and is conducive to greatly improve screening efficiency; Also alleviated sieve axle weight and also alleviated motor load, more secondly also reduced manufacturing cost simultaneously.
(9) the adjustable function of particle diameter: when the required screening of operating mode is more than two kinds during particle diameter, can realize by increasing or reduce grating quantity on grating sieve axle the demands of two kinds of above particle diameters screening operating modes.
