Description

Band rotates the broken mud feed bin that encircles mechanism
Technical field
The utility model relates to technical field of sludge treatment, is a kind of with rotating the broken mud feed bin that encircles mechanism specifically, is particularly useful for the flat shape feed bin of sewage or full-bodied sticky material.
Background technology
In current sewage treatment plant, treatment process is sewage becomes water ratio about 98% after the processing of process chemical method in the pond sewage, enter into the sludge filter cake that diaphragm filter press carries out becoming behind the mechanical dehydration water ratio 60%-70% by transmission pump, carry out drying and other treatment after depositing through the mud feed bin again, reach desired water ratio (below 45%) back entrucking and transport.Because the mud of water ratio 60%-70% has heavy body, characteristics such as tack is strong, rely on the gravity of himself to be difficult to flow to bin outlet, phenomenons such as arch camber, sticking storehouse, obstruction take place in feed bin easily, and feed bin is in case stop up, not only have influence on giving full play to of feed bin effect, also havoc the continuity of production process.Therefore, as how the safest, the most energy-conservation, method is removed situations such as feed bin arch camber, obstruction, sticking storehouse the most rapidly, has become urgent problem.
The method of current broken arch is more, and artificial broken arch, the broken arch of waterpower, the broken arch of wind-force, the broken arch of vibrations, the broken arch of mechanical device etc. are arranged.Wherein adopting the broken arch of balladeur train is current use a kind of arch breaking apparatus comparatively very widely, and the mud feed bin of studying for representative as the general thatch maistre of Germany, Shi Weiying etc. all is to adopt balladeur train to break arch.This device is for to be provided with brokenly the cascade frame in the lower end of feed bin, and balladeur train is placed on the guide rail, and the linear slide back and forth of not stopping under the driving of power system realizes broken arch.This technology can effectively solve the arch camber problem of material, but have following problem: (1) a large amount of material is pressed on the balladeur train, balladeur train directly slides at guide rail, balladeur train be subjected to very big pressure and friction coefficient big, need very big hydraulic pressure could drive balladeur train work, also namely require bigger Hydraulic Station and power consumption that hydraulic-driven power is provided; (2) if between balladeur train and guide rail, roller is set, make balladeur train roll at guide rail, balladeur train is become friction of rolling by cliding friction, though can reduce the pulling force of balladeur train, for the seal request height of roller; (3) because the push-and-pull back and forth that balladeur train does not stop always, and directly contact contains hard sandstone etc. between balladeur train and the guide rail in the materials such as mud, and balladeur train and guide rail are wearing and tearing after the motion for a long time easily, be difficult to ensure the horizontal motion of the hydraulic ram that drives balladeur train, cause the damage of oil cylinder; (4) push-and-pull that is not stopping along with balladeur train, balladeur train with mud squeeze pile up feed bin on the two side, the mud of feed bin both sides can be piled up more and morely and balladeur train pushes more and more solidly, will influence the stroke of oil cylinder as untimely cleaning, and serious meeting damages hydraulic ram.
