Description
Technical field
This utility model relates to filter, a kind of filter filtered after strong phosphoric acid adds activated carbon decolorizing.
Background technology
In industrial phosphoric acid production process, the filter that strong phosphoric acid decolorization filtering uses is vertical filter, on chimney filter
End is fixed on card, and chimney filter lower end is sealing state, does not fixes, side-fed during work, upper end discharging, and bottom end cover is opened and unloaded
Slag.Its shortcoming is to filter after each cleaned filter, and before filter cake is formed, the sour quality in chimney filter is defective, owing to being from upper
End flows out, then need displacement to be lot more time to qualified.If using lower end discharging, then cannot slag dumping.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of strong phosphoric acid decolorizing filter, can solve acid quality
Defective or cannot the problem of slag dumping, it is qualified quickly the acid in chimney filter to be replaced, slag dumping and easy to clean.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of strong phosphoric acid decolorizing filter,
Including support, support being provided with filter housing, between filter housing and horizontal plane, a at an angle arranges, filters
Device shell two ends are each provided with card, and card is the plate body offering multiple installing hole, many two ends screwed chimney filter cloth
Connecting in being placed in filter housing and by fixing bolt and two cards are fixing, filter housing two ends are provided with end cover,
Filter housing top is provided with charging aperture, and filter housing bottom is provided with unloads cinder notch, near the sealed end unloading cinder notch side
Cover and be provided with discharging opening.
A=0-90 degree.
Charging aperture is arranged at the upper lateral part away from the filter housing unloading cinder notch.
The strong phosphoric acid decolorizing filter that this utility model provides, has the beneficial effect that:
1, easy to use, can the most arbitrarily regulate filter angle of inclination.
2, before filter cake is formed, the defective phosphoric acid velocity of discharge is fast, is not detained in chimney filter, when substantially reducing initial filter
Between, improve production efficiency.
3, unload cinder notch to be opened on filter housing, after each filter cycle terminates, slag dumping and easy to clean.
Can solve acid quality defective or cannot the problem of slag dumping, can be quickly by qualified for the acid displacement in chimney filter, slag dumping
With easy to clean.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view that this utility model chimney filter is arranged on card；
Fig. 3 is the front view that this utility model chimney filter is arranged on card.
Detailed description of the invention
As Figure 1-3, a kind of strong phosphoric acid decolorizing filter, including support 5, support 5 is provided with filter housing 1,
Between filter housing 1 and horizontal plane, a at an angle arranges, filter housing 1 two ends are each provided with card 3, and card 3 is
Offer the plate body of multiple installing hole, in the many screwed chimney filters in two ends 2 are arranged in filter housing 1 and by fixing spiral shell
Bolt 6 is fixing with two cards 3 to be connected, and filter housing 1 two ends are provided with end cover 4, and filter housing 1 top is provided with charging
Mouth 7, filter housing 1 bottom is provided with unloads cinder notch 9, is provided with discharging opening 8 near unloading on the end cover 4 of cinder notch 9 side.
A=0-90 degree.
Charging aperture 7 is arranged at the upper lateral part away from the filter housing 1 unloading cinder notch 9.
Work process of the present utility model is as follows:
1, clean qualified this utility model, the strong phosphoric acid of activated carbon will be contained after decolouring by the charging aperture 7 of filter housing 1
Adding, initial activity charcoal can form filter cake outside each chimney filter 2, and defective phosphoric acid is quickly arranged by the discharging opening 8 of filter housing 1
Go out.
2, after filter cake reaches certain thickness, the discharging opening 8 of filter housing 1 is discharged phosphoric acid and is transferred qualified phosphoric acid to, then will
Qualified phosphoric acid collects phosphoric acid groove.
3, once thickened when filter cake enters, when filter capacity is reduced to a certain degree can not meet production, then stopped to charging
Mouthfuls 7 chargings, stop discharging opening 8 discharging, open and unload cinder notch 9 and draw off activated carbon filter cake, and add water flushing to cleaning conjunction at charging aperture 7
Lattice.
Can solve acid quality defective or cannot the problem of slag dumping, can be quickly by qualified for the acid displacement in chimney filter, slag dumping
With easy to clean.
