Abstract
The utility model relates to a novel rotary vibrating screen and aims to solve the problem that as a screen mesh of the existing rotary vibrating screen is often damaged, and a beam ring buckle is locked between an upper screen drum and a lower screen drum, the rotary vibration sieve continuously vibrates during work and is often tripped. The novel rotary vibrating screen comprises a cylindrical base and a screen drum; a vibration generating device and a drive motor are contained in the cylindrical base; a coarse material outlet and a fine material outlet are formed outside the screen drum; the screen mesh and a fine material disc are contained in the screen drum; a screen cover is arranged on the screen drum; and a feeding port is formed in the screen cover. The novel rotary vibrating screen is characterized in that a buffer mixer is arranged in the screen drum, positioned above the screen mesh and aligned with a matched feeding pipe. The screen drum comprises an upper drum and a lower drum which are connected through a bolt; the screen mesh is positioned at the lower part of the upper drum; and the fine material disc is positioned at the lower part of the lower drum. The novel rotary vibrating screen has the advantages of simple structure, convenience in disassembly and assembly, long service life of the screen mesh and long work period, is suitable for screening various slurries and is particularly suitable for screening coal water slurries.
Description
Technical field
The utility model relates to a kind of novel sieve that shakes that revolves.
Background technology
Existing when revolving the sieve that shakes and handling water-coal-slurry, the water-coal-slurry that contains a large amount of coal grains is directly washed away screen cloth, every at a distance from the couple of days screen cloth will repair and replacement once; Cause frequent parking; Be unfavorable for long-period stable operation, and adopt the beam ring padlock tight between the upper and lower screen drum, and revolve the riddler that shakes when doing; Ceaselessly the dropout accident often takes place in vibration.
The utility model content
The technical problem that the utility model will solve is the above-mentioned defective that how to overcome prior art, and a kind of novel sieve that shakes that revolves is provided.
For solving the problems of the technologies described above, this novel sieve that shakes that revolves comprises cylindrical base and screen drum; Cylindrical base includes vibration generating arrangement and drive motors, and screen drum is provided with coarse fodder outlet and fine fodder outlet outward, and screen drum includes screen cloth and fines dish; Screen drum is provided with the sieve lid, and sieve covers and has charging aperture, it is characterized in that: be provided with the buffering blender in the said screen drum; This buffering blender is positioned at the screen cloth top, over against the feed pipe of adapted.So design, behind the installation buffering blender, three months nothings of screen cloth continuous operation are damaged.
As optimization, said screen drum comprises top cylinder and doffing, and the two connects through bolt, and wherein screen cloth is positioned at the top cylinder bottom, and the fines dish is positioned at the doffing bottom.So design, the dropout accident has been stopped in fixation, and folding is adorned, maintenance is convenient.
As optimization, said buffering blender is in the form of annular discs, and its periphery is provided with downflow weir.So design fully mixes in water-coal-slurry and other materials shallow liquid in downflow weir, and then gets into thick slurry and revolve the sieve that shakes, when playing cushioning effect, and the effect that also played mixing, is uniformly distributed with.
This is novel to revolve the sieve that shakes and has simple in structure, easy accessibility, screen life-span is long, the work period is long advantage, is suitable for screening various slurries, is particularly suitable for the screening water coal slurry.
Description of drawings
Below in conjunction with accompanying drawing this novel sieve that shakes that revolves is described further:
Fig. 1 is this novel structural representation that revolves the sieve that shakes.
Among the figure: 1 be cylindrical base, 2 for coarse fodder outlet, 3 for the fine fodder outlet, 4 for the sieve lid, 5 for the buffering blender, 6 for feed pipe, 7 for top cylinder, 8 be doffing.
The specific embodiment
Embodiment one: as shown in Figure 1, this novel sieve that shakes that revolves comprises cylindrical base 1 and screen drum, and cylindrical base 1 includes vibration generating arrangement and drive motors; Screen drum is provided with coarse fodder outlet 2 and fine fodder outlet 3 outward, and screen drum includes screen cloth and fines dish (not shown), and screen drum is provided with sieve and covers 4; Sieve covers and has charging aperture on 4; It is characterized in that: be provided with buffering blender 5 in the said screen drum, this buffering blender 5 is positioned at the screen cloth top, over against the feed pipe 6 of adapted.Said buffering blender 5 is in the form of annular discs, and its periphery is provided with downflow weir.
Said screen drum comprises top cylinder 7 and doffing 8, and the two connects through bolt 9, and wherein screen cloth is positioned at top cylinder 7 bottoms, and the fines dish is positioned at doffing 8 bottoms.
