Description
Technical field
The present invention relates to aluminum oxide production device vertical-disk filter, the blowing point of a kind of novel vertical-disk filter cake discharge
Stream pressurized construction.
Background technology
Vertical-disk filter is the visual plant in alumina producing, is responsible for the aluminum hydroxide slurry in seeded precipitation operation
Separate, to provide corresponding crystal seed and mother solution.Vertical-disk filter cake discharge mainly passes through the dispensing head back-blowing mouth of pipe at main shaft
Blow malleation wind when forwarding discharge zone to main shaft storehouse, malleation wind is delivered to filter disc fan intralaminar part by main shaft storehouse, makes fan intralaminar part pressure
Power is more than external pressure, thus discharging of blowing off.
At present, the main shaft of import and the domestic vertical-disk filter blowing many employings in storehouse " trapezoidal add taper ", malleation wind is become owner of
During axle, allocation of the amount of air is uneven, and first row filter disc (near distribution rostral) distribution air quantity is superfluous, and second, third row takes second place, the 4th row
Filter disc (distance dispensing head distalmost end) distribution air quantity is minimum, there are about 150-200mm between main shaft storehouse bottommost and the 4th row's filter disc
So-called " dead band ".Malleation wind easily forms " eddy current " at " dead band " place, and " eddy current " wind can be offset a part and be arrived the after being formed
The malleation wind of four row's filter discs, material properties change (material viscosity increase) during causing vertical plate to use, make the 4th row's filter disc filter
Cake discharging is not smooth, the 4th row's not discharging substantially time serious, and production capacity reduces, causes the equipment underproduction.To this end, equipment uses producer the most general
This problem is solved all over using the method improving blowback malleation wind pressure.After blowback malleation wind pressure increases, although can make
There is a change for the better in 4th row's filter disc discharging, but to also result in first row filter disc malleation wind air quantity superfluous simultaneously, reduces first row
Filter disc fan plate and the service life of filter cloth.Moreover, improve blowback malleation wind pressure and too increase energy resource consumption, increase and produce into
This.
Summary of the invention
For the drawback overcoming the deficiency existing for domestic and international vertical-disk filter to bring to production, we are to vertical-disk filter
Carried out structure improvement, have developed a kind of novel vertical-disk filter cake discharge blowing shunting pressurized construction, the improvement of this structure, no
But the problem solving the not smooth underproduction of vertical-disk filter filter disc cake discharge discharging, in the case of not improving energy resource consumption, i.e. improves
Production capacity, will not reduce again fan plate and service life of filter cloth.
The present invention adopts the following technical scheme that a kind of novel vertical-disk filter cake discharge blowing shunting pressurized construction, its feature
Being: arrange flow distribution plate below corresponding each diffluence pass in main shaft storehouse, flow distribution plate is welded on main shaft bulkhead, and main shaft storehouse is split
Become upper and lower two-layer, flow distribution plate angle all at an acute angle with diffluence pass, deflector, deflector end are set below the end diffluence pass of main shaft storehouse
End is welded on main shaft Hold Ceiling, and near end diffluence pass, deflector front end is welded on the base plate of main shaft storehouse, with end diffluence pass
Angle the most at an acute angle.
Described flow distribution plate, deflector are according to process and equipment thickness value between 8mm～12mm.
Described deflector and end diffluence pass inclination angle >=45 ° ,≤60 ° of values.
Beneficial effect: owing to using above structure, flow distribution plate has shunted air quantity effectively, makes each diffluence pass air quantity more equal
Weighing apparatus, deflector eliminates main shaft storehouse end eddy current, makes end diffluence pass air quantity increase, in the case of not increasing plant capacity,
Customer service end filter disc cake discharge is smooth due to deficiency in draught discharging, or the problem of not discharging.Improve the production capacity of vertical-disk filter,
And save the energy, add spare part service life.

Detailed description of the invention
As it is shown in figure 1, a kind of novel vertical-disk filter cake discharge blowing shunting pressurized construction, each point of correspondence in main shaft storehouse
Arranging flow distribution plate below head piece, flow distribution plate is welded on main shaft silo wall, and main shaft storehouse is divided into upper and lower two-layer, flow distribution plate all with
Diffluence pass angle at an acute angle, arranges deflector below the end diffluence pass of main shaft storehouse, deflector end is welded on main shaft Hold Ceiling,
Near end diffluence pass, deflector front end is welded on the base plate of main shaft storehouse, angle the most at an acute angle with end diffluence pass.Equipment runs
During, malleation wind is divided into two parts through diffluence pass A, and the top malleation wind being split is absorbed by first row filter disc, is divided
The bottom malleation wind of stream continues through main shaft storehouse 5 and carries inwards, sequentially passes through diffluence pass B, diffluence pass C and continues shunting, to main shaft
During 5 bottommost of storehouse, malleation wind is directly transported to diffluence pass D by deflector 4.
