Description
Technical field
It is especially a kind of to add the filter filtered after activated carbon decolorizing for concentrated phosphoric acid the present invention relates to filter.
Background technology
In industrial phosphoric acid production process, the filter that concentrated phosphoric acid decolorization filtering uses is vertical filter, and chimney filter upper end is fixed on card, and chimney filter lower end be sealing state, is not fixed, side-fed during work, upper end discharging, bottom end cover opening slag dumping.Its shortcoming is filtered after cleaning filter every time, and before filter cake is formed, the sour quality in chimney filter is unqualified, due to being flowed out from upper end, then needs displacement to be lot more time to qualified., can not slag dumping if discharged using lower end.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of concentrated phosphoric acid decolorizing filter, can solve the problems, such as sour quality it is unqualified or can not slag dumping, can be quickly qualified by the acid displacement in chimney filter, slag dumping and easy to clean.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of concentrated phosphoric acid decolorizing filter, including support, filter housing is installed on support, a arrangements at an angle between filter housing and horizontal plane, filter housing both ends are each provided with card, card is the plate body for offering multiple mounting holes, the more screwed chimney filters in both ends are arranged in filter housing and are fixedly connected by fixing bolt with two cards, filter housing is provided at both ends with end cover, filter housing top is provided with charging aperture, filter housing bottom, which is provided with, unloads cinder notch, close to unloading discharging opening is provided with the end cover of cinder notch side.
A=0-90 degree.
Charging aperture is arranged at the upper lateral part away from the filter housing for unloading cinder notch.
Concentrated phosphoric acid decolorizing filter provided by the invention, has the beneficial effect that：
1st, it is easy to use, filter angle of inclination can be arbitrarily adjusted as needed.
2nd, before filter cake is formed, the unqualified phosphoric acid velocity of discharge is fast, is not detained in chimney filter, substantially reduces the initial filter time, improves production efficiency.
3rd, cinder notch is unloaded to be opened on filter housing, after each filter cycle terminates, slag dumping and easy to clean.
Can solve the problems, such as sour quality it is unqualified or can not slag dumping, can be quickly qualified by the acid displacement in chimney filter, slag dumping and easy to clean.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the top view that chimney filter of the present invention is arranged on card；
Fig. 3 is the front view that chimney filter of the present invention is arranged on card.
Embodiment
As Figure 1-3, a kind of concentrated phosphoric acid decolorizing filter, including support 5, filter housing 1 is installed on support 5, a arrangements at an angle between filter housing 1 and horizontal plane, the both ends of filter housing 1 are each provided with card 3, card 3 is the plate body for offering multiple mounting holes, the screwed chimney filter 2 in more both ends is arranged in filter housing 1 and is fixedly connected by fixing bolt 6 with two cards 3, filter housing 1 is provided at both ends with end cover 4, the top of filter housing 1 is provided with charging aperture 7, the bottom of filter housing 1, which is provided with, unloads cinder notch 9, close to unloading discharging opening 8 is provided with the end cover 4 of the side of cinder notch 9.
A=0-90 degree.
Charging aperture 7 is arranged at the upper lateral part away from the filter housing 1 for unloading cinder notch 9.
The course of work of the present invention is as follows：
1st, the qualified present invention is cleaned, the concentrated phosphoric acid containing activated carbon after decolouring is added by the charging aperture 7 of filter housing 1, initial activity charcoal can form filter cake in each outside of chimney filter 2, and unqualified phosphoric acid is quickly discharged by the discharging opening 8 of filter housing 1.
2nd, after filter cake reaches certain thickness, the discharging opening 8 of filter housing 1 discharges phosphoric acid and switchs to qualified phosphoric acid, then qualified phosphoric acid is collected into phosphoric acid groove.
3rd, once thickened when filter cake enters, filter capacity is reduced when can not meet production to a certain extent, then stops feeding to charging aperture 7, stops discharging opening 8 and discharge, and opening unloads cinder notch 9 and draws off activated carbon filter cake, and it is qualified to cleaning in charging aperture 7 to add water to rinse.
Can solve the problems, such as sour quality it is unqualified or can not slag dumping, can be quickly qualified by the acid displacement in chimney filter, slag dumping and easy to clean.
