Abstract
The utility model discloses filter cloth flushing equipment for a belt filter. The filter cloth flushing equipment comprises a support pipe (1), a water inlet main pipe (2), a slag moisturizing pipe (3), a slag flushing pipe (4), a backsurge pipe (5) and control valves (6), wherein the support pipe (1) and the water inlet main pipe (2) form a support frame; the slag moisturizing pipe (3) is arranged at the upper part of the support frame; the slag flushing pipe (4) is arranged in the middle of the support frame, and the backsurge pipe (5) is arranged at the lower part of the support frame; and the control valves (6) are mounted at the water inlet ends of all the pipes. The filter cloth flushing equipment can be manufactured simply, solves the problems that the belt filter requires lots of flushing water and can not flush cleanly, and reduces the filter cloth flushing water by about 20% and the phosphorus content of a filter cake by about 0.5-1%.
Description
Technical field
The utility model relates to separation, relates in particular to a kind of band filter filter cloth washing equipment in the wet phosphoric acid purifying process.
Background technology
In the wet phosphoric acid purifying process, be to guarantee large-scale production, use band filter that the particulate matter in the acid is carried out isolated by filtration at the production link of preliminary treatment acid.In order to guarantee that filter cloth cleans up, must wash with a large amount of flushing waters at present, but still have a small amount of filter residue to take away with filter cloth and drop to be deposited in below the band filter frame, need stop during cleaning and expend great amount of manpower.Because flushing does not totally cause the filter opening of filter cloth to stop up, and has a strong impact on filter effect.
Summary of the invention
The purpose of this utility model be to overcome above-mentioned difficulties and provide a kind of simple in structure, easy to operate, save flushing water and guarantee the flushing device of developing result.
Band filter filter cloth washing equipment of the present utility model comprises: slag pipe, flushing cinder pipe, recoil tube and by-pass valve control are responsible for, are moistened in stay pipe, water inlet; Stay pipe is responsible for water inlet and is formed bracing frame; Profit slag pipe is on the top of bracing frame, and the flushing cinder pipe is at the middle part of bracing frame, and recoil tube is in the bottom of bracing frame; The entrance point of each pipeline arranges the water control valve door.
The material of described pipeline customizes according to flushing water quality.
Described recoil tube adopts pipeline boring and forms, and pitch of holes is 1cm.
The utility model moistens the upper end that the slag pipe is arranged on band filter outlet cylinder in use, and filter cloth separates the place with belt.The flushing water outlet pressure is less than 0.1MPa, and infiltrating time is controlled the second at 10-12.The flushing cinder pipe is arranged on the vertical plane of filter cloth.The flushing water outlet pressure is 0.4-0.5MPa, and amount of flush water is about 60% of Total Water, and the filter residue on the filter cloth that guarantees to be invisible to the naked eye is as the criterion, and washing water quantity is regulated by control valve; Recoil tube is arranged between the filter cloth cylinder, the back side of filter cloth, and flushing water washes to the front from the back side of filter cloth, and the bath outlet pressure guarantees that 0.5-0.6MPa is advisable, and mainly washes the filter residue in the filter cloth filter opening.
The utility model is compared with other flushing devices, simple in structure, processing extremely easy to use, particularly filter residue is soaked into after, make the flushing cinder process become very easy, and can economize on water about 20%, can guarantee the normal operation of band filter fully, greatly improved the operational efficiency of band filter, and made the phosphorus content of the filter cake 0.1-1% that descended.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
1, stay pipe 2, water inlet are responsible for 3, are moistened slag pipe 4, cleaning hose 5, recoil tube 6, by-pass valve control.
