Abstract
The utility model relates to a rolling separation sieve with a sieve cleaning device, which solves the problem that the existing rolling separation sieve has low sieving efficiency, high energy consumption and large mechanical wear caused by the blockage of sieve holes. The utility model comprises a main axis, a plurality of circular rings and a plurality of straight rods, wherein the main axis is arranged on a bearing seat connected with a sieve seat. The axial lines of the circular rings are alternately arranged on the axial line of the main axis. The straight rods are parallel to the main axis and are in contact with the inner circumference surface of each circular ring. The main axis is connected with each straight rod by a supporting strip, and the sieve seat is provided with a roller shaft parallel to the main axis. Rollers which can rotate around the roller shaft are alternately arranged on the roller shaft, and the outer margin of each roller extends between two adjacent circular rings. The roller shaft and the rollers form the sieve cleaning device which can ensure that each sieve hole is always in the unimpeded state. Thus, the utility model can raise sieving efficiency, decrease energy consumption and reduce mechanical wear.
Description
Technical field
The utility model relates to a kind of rolling separating screen, particularly a kind of rolling separating screen with screen cleaning device.
Background technology
At present, mostly divide form particularly at the sieving machine of industry institute extensive uses such as power plant, mine, cement, the drum screen branch form used is also arranged for horizontal screen industrial.But no matter use any form, when being sized thing such as station-service coal and sieving, because of there are characteristics such as sticking, wet, dirty, assorted in the material that is sized, it very easily stops up sieve aperture in screening process, cause screening efficiency low, cause that energy consumption is too high, mechanical wear is big, thereby had a strong impact on the operate as normal of screening plant.
Summary of the invention
The technical problem that the utility model solves is the problem that existing rolling separating screen is low because of the screening efficiency that sieve pore blockade causes, energy consumption is high.
The purpose of this utility model is achieved through the following technical solutions: the rolling separating screen of this band screen cleaning device, comprise be arranged on sieve the bearing block that links to each other of seat on main shaft, the spaced annulus of several axis on main-shaft axis, the several straight-bars parallel with main shaft and the inner peripheral surface of each annulus join, main shaft is connected by support bar with every straight-bar, the sieve seat is provided with the roller shaft parallel with main shaft, being spaced on roller shaft can be around the roller of roller shaft rotation, and the outer rim of each roller extend between two adjacent annulus.Roller shaft and roller have promptly constituted screen cleaning device.
When using the utility model, actuating unit drives main axis rotation, and main shaft drives straight-bar, rotates with the continuous annulus of straight-bar by support bar.Be sized the end adding that separate screen drum of material from straight-bar and annulus composition, tiny material falls from the sieve aperture that adjacent two straight-bars, two adjacent annulus surround.
If there is material to be blocked in the sieve aperture, because the roller outer rim of screen cleaning device stretches between two adjacent annulus, roller can contact with these blocked materials, thereby it is ejected sieve aperture, reach the purpose of cleaning sieve aperture, guarantee that each sieve aperture is in unobstructed state all the time.Can improve screening efficiency like this, cut down the consumption of energy, mechanical wear is big.
If the utility model work long period has the part twister and hangs on screen cleaning device or other device, only need pull down screen cleaning device and clear up this moment.For the ease of dismounting, as to improvement of the present utility model, roller shaft links to each other with the sieve seat by connecting rod, and an end and the roller shaft of connecting rod join, and the other end becomes flexible connection with sieving.
Certainly, for convenient to the screen cleaning device cleaning, as to further improvement of the utility model, sieve seat and be provided with limited block, the other end of connecting rod is connected with hinging manner with the sieve seat; When connecting rod around hinge through to a certain position and with limited block mutually by the time, the outer rim of roller extend between two adjacent annulus.This rotational structure can be with screen cleaning device around hinge through to a certain position, convenient cleaning work also makes the installation of screen cleaning device, maintenance convenient, has alleviated operating personnel's working strength.
For any rolling separating screen recited above, support bar have two groups or more than, every group of support bar is on same circular section, a support bar and a vertical straight-bar in every group of support bar join; Every support bar and main shaft are perpendicular.
For any rolling separating screen recited above, described several straight-bars can be distributed on the inner peripheral surface of annulus.
Description of drawings
Fig. 1 is structural representation of the present utility model (the A-A cutaway view of Fig. 2);
Fig. 2 is the left view (removing sieve seat 1) of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment.
The rolling separating screen of the screen cleaning device of band shown in the figure, comprise and be arranged on and sieve the main shaft 2 of seat on the 1 bearing block (not shown) that links to each other, the spaced annulus 3 of several axis on main-shaft axis, the straight-bar 4 that the six roots of sensation is parallel with main shaft and the inner peripheral surface of each annulus join, and straight-bar 4 is distributed on the inner peripheral surface of annulus 3.
Roller shaft 6 and spacedly on roller shaft 6 can promptly constitute screen cleaning device 8 around the roller 7 that roller shaft rotates.Screen cleaning device 8 has three groups, and it is identical that each organizes structure.
Roller shaft 6 in the screen cleaning device 8 links to each other with axle 10 by two connecting rods 9, and connecting rod 9 can rotate around axle 10, and axle 10 links to each other with sieve seat 1.Sieve seat 1 is provided with limited block 12, when connecting rod 9 around axle 10 turn to a certain position and with limited block 12 mutually by the time, the outer rim of roller 7 extend between two adjacent annulus 3.
When using the utility model, actuating unit drives main shaft 2 rotations, and main shaft 2 drive support bars 5, straight-bar 4, annulus 3 rotate together.Be sized the end adding that separate screen drum of material from straight-bar 4 and annulus 3 compositions, tiny material falls from the sieve aperture 11 that adjacent two straight-bars, two adjacent annulus surround.
If some material is blocked in the sieve aperture 11, because the outer rim at roller stretches between two adjacent annulus 3, roller 7 can contact with these blocked materials, thereby it is ejected sieve aperture, reach the purpose of cleaning sieve aperture, guarantee that each sieve aperture is in unobstructed state all the time.
Every group of screen cleaning device 8 and connecting rod 9 can rotate around axle 10, and screen cleaning device 8 can rotate and leave the separation screen drum when shutting down like this, is convenient to clear up the foreign material that reside on the screen cleaning device, make also that screen cleaning device is convenient to install, maintenance, have reduced operating personnel's working strength.
When the utility model is widely used in power industry,, when selecting coal breaker, can select the specification of exerting oneself more for a short time by separating the load that can alleviate coal breaker greatly, reduce cost of investment, simultaneously can significantly reduce the operation power consumption in actual motion, energy savings reduces cost; In other industries such as cement, also can produce better economic and social benefit.
