Abstract
The utility model discloses a hammer-externally-arranged screen-ring-structured rotary screen unblocking device. The device comprises a hammer installing base, an external hammer, a hinge pin, a retainer ring and a cotter pin. Due to the application of the structure, when a rotary screen is running, the hammer constantly hits a vibrating screen ring so as to carry out unblocking on the rotary screen, in such a way, an operation of stopping the rotary screen to carry out regular unblocking is not required, and an effect that a device can be subjected to unblocking while running, therefore, the unblocking device is time-saving, labor-saving, non-stick and non-clogging, high in screening efficiency, and convenient to maintain.
Description
Technical field
The utility model belongs to thermal power generation and coal chemical technology, is specifically related to a kind of sieve ring structure rotary screen.
Background technology
At present; With the burning low grade coal is that rise rapidly at home in main comprehensive utilization power station (being mainly CFBB); With coal ore, coal slime is that master's fuel exists characteristics such as sticking, wet, dirty, assorted usually; Phenomenons such as coal handling system ubiquity screening system stops up, screening efficiency is low cause the disintegrating machine wearing and tearing of screening system rear end big, energy consumption is high.In addition, the big more options rotary screen of screening plant in the defeated screen subsystem of tradition, and the conventional rollers sieve adopts mesh structure mostly, it is crisscross that promptly screen cloth adopts round wire, is compiled into the mesh screen lattice.Receive structural limitations, this type rotary screen needs regular block clearing, and manual cleanup or high pressure water washing are adopted in the block clearing measure usually, must open seal cover during block clearing, and block clearing is built seal cover after accomplishing again.Therefore, repair and maintenance takes time and effort, and is extremely inconvenient.For this reason, my company improves mesh structure, has released sieve ring structure rotary screen as shown in Figure 1; And disposed tup formula block clearing device in sieve ring inboard; Be the built-in block clearing device of tup (4), in rotary screen work, material cleared up through the strike vibration of external tup (8); Thereby it is not stifled to have guaranteed that rotary screen cannot not remain stickingly in screening process, and screening efficiency significantly improves than conventional screen web frame rotary screen.
But along with the continuous upset of drum apparatus (3), the built-in tup (8) that is in the roller tube lower inside has the situation of being buried by material unavoidably in the material screening process; At this moment; Not only reduced strike effect, and the tup of burying can block the part compass screen surface, pass through area thereby reduce partial material; Therefore screening efficiency is had certain influence inevitably, reduce screening efficiency; Simultaneously, at first must open seal cover (2) during block clearing device (4) repair and maintenance, the repair and maintenance personnel enter in the rotary screen cylindrical shell more afterwards, can carry out, and repair and maintenance is extremely inconvenient.
Summary of the invention
To above-mentioned deficiency, it is a kind of time saving and energy saving that the utility model provides, and not sticking not stifled, screening efficiency is high, and repair and maintenance is tup external sieve ring structure rotary screen block clearing device easily.
The utility model is to realize through such technical scheme: a kind of tup external sieve ring structure rotary screen block clearing device, this device comprises tup mount pad, external tup, bearing pin, back-up ring, split pin.The external tup is through on the tup mount pad through bearing pin, is divided into plurality of rows and distributes in length and breadth, and the supplied materials direction forms and repeatedly hits vibration along the equipment top during equipment work.
Adopted the sieve ring structure rotary screen of said structure, during work, because the inclination and the rotation of drum apparatus; Make materials overturning and rolling on the compass screen surface; Qualified material is discharged through the fines discharge bucket of bottom, and underproof material is discharged through the coarse fodder discharge bucket of bottom, simultaneously; Because the strike of external tup vibration is ejected the material that is stuck in the sieve czermak space.Because the external tup is installed in the cylinder outside; Along with the continuous upset of cylinder, the external tup that is in the cylinder bottom is under the effect of himself gravity, straight down in the material screening process; Unlikely sieve ring grizzly face is caused blocked; Material fully is guaranteed through area, and not sticking not stifled, screening efficiency is high; Simultaneously, because the block clearing device is arranged in the cylinder outside, only need opens seal cover during repair and maintenance and can carry out, repair and maintenance is convenient.

Fig. 3 is tup external sieve ring structure rotary screen structure chart.
Fig. 4 is tup external sieve ring structure rotary screen tup distribution schematic diagram.
Fig. 5 is the structural representation of tup external sieve ring structure rotary screen block clearing device among this case embodiment.
Mark among the figure: 1 dynamical system, 2 seal covers, 3 drum apparatus, the built-in sieve ring structure of 4 tups rotary screen block clearing device, 5 frames, 6, coarse fodder discharge bucket 7 fines discharge buckets, 8 built-in tups, 9 tup externals sieve ring structure rotary screen block clearing device, 10 tup mount pads, 11 external tups, 12 bearing pins, 13 back-up rings, 14 split pins.
The specific embodiment
For purpose, technical scheme and the beneficial effect that is expressly understood the utility model more, below in conjunction with accompanying drawing the utility model is done further explanation, but the protection domain of the utility model is not limited in following examples.
To shown in Figure 5, a kind of tup external sieves ring structure rotary screen block clearing device like Fig. 3, and this device comprises tup mount pad (10), external tup (11), bearing pin (12), back-up ring (13), split pin (14).
Said tup mount pad (10) welding is fixed on drum apparatus (3) the cylindrical shell cylindrical, and external tup (11) is through on the tup mount pad (10) through bearing pin (12), fixes through back-up ring (13), split pin (14) combination.
During rotary screen work, dynamical system (1) drives drum apparatus (3) and rotates around its axis, after material gets into drum apparatus; Because the inclination and the rotation of cylinder make materials overturning and rolling on the compass screen surface, make qualified material (undersize; Be fines) to discharge through the fines discharge bucket (7) of bottom, underproof material (oversize, i.e. coarse fodder) is discharged through the coarse fodder discharge bucket (6) of bottom; Simultaneously, be distributed in the drum movement of the external tup in the cylinder outside, when it runs to the cylinder top with rotation; Under cylinder rotational component, inertia force and tup self-gravity action, obtain kinetic energy; Tup rushes at cylinder along the bearing pin rotation, forms the strike vibration to cylinder, and the material that is stuck in the sieve czermak space is ejected; The external tup is that plurality of rows distributes in length and breadth, and the supplied materials direction forms and repeatedly hits vibration along the equipment top during rotary screen work; The tup that runs to cylinder below is under the effect of himself gravity, and straight down, unlikely sieve ring grizzly face is caused blocked, and material fully is guaranteed through area, and sticking stifled, screening efficiency is high.Because block clearing device (9) is arranged in the cylinder outside, only need open seal cover (2) during repair and maintenance and can carry out, and enter into operation in the rotary screen cylindrical shell again and need not the repair and maintenance personnel, so repair and maintenance is convenient.
To sum up, the rotary screen that adopts the utility model structure is in the process of work, and tup constantly hits the vibratory sieve ring, and rotary screen is carried out block clearing; And need not to shut down regular block clearing, the block clearing of equipment is carried out in work simultaneously, and is time saving and energy saving; Not sticking not stifled, screening efficiency is high, and repair and maintenance is convenient.
