Abstract
The utility model discloses a rotation mechanical bar screen, it sets up the flexible harrow bars area in grid frame cell body including the grid frame cell body of slope setting to and be used for driving rot. Rotary sprocket in flexible harrow bars area and chain, flexible harrow bars area comprises the mutual rectangle harrow bars and the trapezoidal harrow bars that set up of separating, rectangle harrow bars and trapezoidal harrow bars include all that both ends all are provided with the enhancement strake at the stainless steel orifice plate of end plate, setting upper and lower both ends between the end plate to and set up two end plate outer ends, be used for the bars axle be connected with the drive chain drive, the upwards installation of bottom surface of trapezoidal harrow bars, and the front portion of point portion towards mechanical bar screen, it blocks dirty precision height, and whole rigidity is good, is favorable to the bars sediment to fall and can take place the winding card hindering the phenomenon, and the bars shape of face that is coupleed in turn by trapezoidal harrow bars and rectangle harrow bars has become a plurality of steps, can drag for large -scale floater.
Description
Technical field
This utility model relates to cities and towns and Industrial Waste Water Treatments factory preprocessing technical field, particularly relates to one
Plant the rotatable mechanical grille with modular flexible harrow grid.
Background technology
At present, the sewage blocking device overwhelming majority being applied to sewage treatment plant's pretreating process section is
Rotatable mechanical grille, this device block dirty work surface (grid face) by several rows of monolithic tooth harrow grid
Bar forms, and the gap formed between tooth harrow grizzly bar became water space (grid gap).Driving dress
Under the driving put, grid face upstream face from bottom to top moves, the foreign material band water outlet that will intercept in water
Face, the effect of rake hook is to pull large-scale floating thing out.When rotatable grid face runs to back side,
From top to bottom moving in grid face, the foreign material (grid slag) on grid face are action of gravity or auxiliary at hairbrush
Effect is helped to drop into (equipment typically tilts backwards 60 °-75 ° installations) in collection device.
This plant automation degree is fine, but and imperfect.Main three aspects of its defect:
One is that filtering accuracy is restricted, and the version of its grizzly bar determines its grid gap can not be less than 5mm,
And the grid of reality application acceptance of the bid fixed grid gap 5mm can be by solid the biggest for diameter 7mm
Particulate matter；Two is monolithic rake hook (being typically stamped to form by the thickness stainless steel plate less than 1mm)
Insufficient strength, the easily deformed damaged when running into large-scale floating thing or fabric, this also becomes
One of modal fault of such device；Three be some dry goods, plastic bags etc. be easily wound around,
Jam, on rake hook and between grid gap, can not come off in slag dumping district and enter current, thus after impact
The techniques such as sequence pumping, filtration are normally carried out.
Utility model content
This utility model purpose is to provide one to have mould for above-mentioned the deficiencies in the prior art
The rotatable mechanical grille of block formula flexible harrow grid.
This utility model realizes above-mentioned purpose and is adopted the technical scheme that: a kind of rotatable machinery
Grid, it includes the grid frame cell body being obliquely installed, is arranged on the net in grid frame cell body
Shape rake grid band, and it is used for revolution sprocket wheel and the chain driving flexible harrow grid band to turn round；Described
Flexible harrow grid band is harrowed grid by the rectangle of spaced setting and trapezoidal rake grid form, described rectangle
Rake grid and trapezoidal rake grid all include that two ends are provided with the rustless steel orifice plate of end plate, are arranged on end plate
Between the reinforcement edge strip at upper and lower two ends, and be arranged on two end plate outer ends, for driving
The grid axle that chain drive connects；The bottom surface of described trapezoidal rake grid is upwards installed, and tip is towards machine
The front portion of tool grid.
Further, it is provided with below described grid frame cell body top and unloads cinder notch.
The beneficial effects of the utility model are: rotatable mechanical grille one of the present utility model is to block
Dirty (filtration) precision is higher, can accomplish 2mm；Two be modular unit be one quite
The rigidity combined in tens monolithic tooth harrow grizzly bars (rectangle rake grid and trapezoidal rake grid) is overall,
Be equivalent to chopsticks tie together its strength and stiffness and increase；Three is grid face flat smooth, has
It is beneficial to grid slag fall and will not occur to be wound around jam phenomenon, trapezoidal rake grid and rectangle harrows grid alternately
The grid face coupled defines multiple step, can pick up large-scale floating thing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of trapezoidal rake grid.
Fig. 3 is the structural representation of rectangle rake grid.
In figure: 1, grid frame cell body；2, flexible harrow grid band；3, revolution sprocket wheel；4, chain
Bar；5, rectangle rake grid；6, trapezoidal rake grid；7, end plate；8, rustless steel orifice plate；9, add
Strong edge strip；10, grid axle；11, cinder notch is unloaded.
Detailed description of the invention
This utility model is below with reference to accompanying drawing further description.
As Figure 1-3, rotatable mechanical grille of the present utility model, it includes being obliquely installed
Grid frame cell body 1, the flexible harrow grid band 2, Yi Jiyong being arranged in grid frame cell body
In the revolution sprocket wheel 3 and the chain 4 that drive the revolution of flexible harrow grid band；Described flexible harrow grid band is
Harrowed grid 5 by the rectangle of spaced setting and trapezoidal rake grid 6 form, described rectangle rake grid 5 He
Trapezoidal rake grid 6 all include being provided with the rustless steel orifice plate 8 of end plate 7 in two ends, and (it is whole by one
Block rustless steel punching web plate bending forms, and its intersection accuracy depends on its aperture size, aperture chi
The very little 2.0mm that can accomplish, mechanical grille therefore can be greatly improved blocks dirty precision)；End plate
And by argon arc welding spot welding link between rustless steel orifice plate, become a rigidity entirety, and at end plate
Termination up and down install and strengthen edge strip 9 so that it is firmer be unlikely to deform；And it is arranged on two
Individual end plate outer end, for and drive the grid axle 10 that is connected of chain drive, for joining with grid axle
Closing, its axis hole and pitch of holes determine according to the diameter of axle and the distance between axles of universal machine grid, in order to
Standardization and renovating, rectangle rake grid and trapezoidal rake grid are alternately mounted on chain by grid axle
On, define a grid face turned；The bottom surface of described trapezoidal rake grid 6 is upwards installed, and point
Portion is towards the front portion of mechanical grille, thus defines step one by one, in order to salvage large-scale drift
Float；It is provided with below described grid frame cell body top and unloads cinder notch 11.
During utility model works state, whole equipment is placed in the most constructed grid canal,
In the lower half encroached water of equipment, work surface meets water, body tilts backwards 60 degree of installations.Work
Make face to move from bottom to top and the float retained salvaged, when work surface rotates to slag dumping district
During 2-6, owing to the effect grid slag of gravity and subsidiary brush falls naturally.
