In addition, existing filtration disk outer rim is prismatic, is not only unfavorable for installing, and is also unfavorable for the normal circulation of bottom land current simultaneously; Form the fanning strip filtering disk to be made up of lath and filter screen, structure is comparatively thin; Filter gap between lath is gradual change form, have impact on filter quality and effect.
By retrieval, find one section of patent document relevant to present patent application:
A kind of improvement (CN201023002) of belt vacuum filter, framework is provided with in vacuum pan, framework is horizontally disposed with little carrying roller supporting drive strainer, using the ring-shaped filtering belt of loopy moving as filter medium, the negative pressure utilizing vacuum equipment to provide and Action of Gravity Field, filtrate infiltration filter cloth, flows into vacuum pan from little carrying roller space, be provided with leakage fluid dram bottom vacuum pan, be connected with liquid header through soft suction hose.Automatically can complete filtration, Washing of Filter Cake continuously, blot, discharging, the technological operation such as filter cloth cleaning.Can decide little carrying roller material according to the extent of corrosion of different filter material, between roller and roller, space controls at 1.8-2.5mm.Have that intensity is high, corrosion-resistant, passage is happy, gas-liquid two-phase can fully circulate, reduce friction, reduce noise, extend strainer service life, save the features such as cost.
Through technical comparison, above-mentioned patent document and the utility model are not identical.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the disk vacuum filter being suitable for processing paper mill sludge and waste water that a kind of scientific structure is reliable, filter quality good, filter effect is excellent.
The purpose of this utility model is achieved by the following technical solution:
A kind of disk vacuum filter being suitable for process paper mill sludge and waste water, comprise filtration cell body, hollow rotating shaft, variable-frequency motor, sewage inlet pipe, sewage goes out pipe, pure water pipe and filtration disk, filtering disk is packed in rotating shaft, filter in cell body and be communicated with sewage inlet pipe respectively and sewage goes out pipe, on hollow rotating shaft, uniform interval is fixedly mounted with filtration disk, filter disk and the water filtered is discharged filtration cell body by hollow rotating shaft through pure water pipe, it is characterized in that: described filtration disk is disc-shaped structure, this filtration disk is made up of multiple identical fanning strip, each fanning strip is by outer rim channel-section steel, limit channel-section steel and outer rim channel-section steel, translot steel between the channel-section steel of limit, support lath and screen pack formation, the outer rim channel-section steel of each fanning strip is arc, be combined into after filtering disk and form discoidal filtration disk, at filtration disk outer package screen pack, the outer rim channel-section steel of adjacent fanning strip adopts clip to carry out outer rim and fixes, and the side of adjacent fanning strip adopts limit channel-section steel to fix, the longitude and latitude of each fanning strip adopts the translot steel at uniform interval, support lath is arranged, translot steel, support lath are uniform interval and arrange.
And the gap of the support lath between described adjacent translot steel is all identical.
And, filter all to be provided with between the adjacent head disk in cell body one with the flushing head of bath cross current, this flushing head is oval chondritic, uniformly on oval ball is shaped with through hole.
Advantage of the present utility model and good effect are:
1, this filter changes outer cause many ribs structure of filtering disk into circular configuration, is conducive to the top formed between the fanning strip filtering disk and compresses and connect, thus improve the reliability of filtering disk and connecting; Meanwhile, the circular configuration filtering disk outer rim is conducive to filtering the flowing of the current bottom cell body, and the good sealing effect with filtering cell body, also effectively improves filter effect.
2, this filter changes by laths of metal the framework filtering disk fanning strip side into channel steel support, and adopt unified forming frock manufacture, production, group right, not only enhance the intensity of fanning strip, be also conducive to ensureing fanning strip appearance and size and presentation quality simultaneously.
3, the longitudinal direction radiation floor filtering disk fanning strip is designed to radiate segmental structure by this filter, makes the gap between floor keep basically identical, greatly can improve the filter efficiency of filtering disk.
4, this filter changes flushing pipeline into uniform current ring-type flushing head by straight tube flushing head, is conducive to the filter effect improving whole fanning strip, improves filter quality, and the filter effect that avoiding directly washes by water simultaneously causes is difficult to the problem ensured.
5, this filter global design science, solve the multiple technologies difficult problem that existing filter exists, improve filter effect and the filter quality of filter, enhance intensity and the behavior in service of fanning strip, be that the novelty of existing filter is improved, facilitate environmental protection and produce.
