Description
Technical field
The utility model relates to sewage water filtration field, particularly relates to a kind of sewage purification filter.
Background technology
In biochemical processing procedure of sewage, certainly lead to a large amount of biochemical sludges and be suspended in and purify waste water.In order to make the middle suspension content of purifying waste water of discharge reach requirement, equipment such as comprising second pond must be adopted to carry out mud-water separation to purifying waste water.Separating effect
Just, directly determine sewage discharge whether to be up to state standards.In existing sedimentation basin technology, owing to being subject to place and cost
Restriction, sedimentation effect is difficult to completely up to standard, and what adopt comprises sloping plate deposition for this reason, the idetified separation modes such as tube settling, although energy
Improve mud-water separation effect, but easily block, safeguard inconvenience, hydraulic performance decline is very fast.Also has the mode adopting membrane filtration, although effect
Fruit very well.But the throughput of film is generally less than 30 L/(m
2and expensive h).The little water yield can only be used for, the occasion of particular/special requirement.
For the deficiencies in the prior art described above, adopting new filtering material and method, reliable regeneration technology system, is all innovative point place of the present utility model.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, designs a kind of filter of unique texture, meets the requirement of sewage water filtration.
Adopt following technical scheme for achieving the above object:
A kind of sewage purification filter, comprise a seal case, box house is provided with upper box and the lower box that seal case is divided into sealing by one piece of dividing plate; The side of described lower box is provided with water inlet, and the bottom surface of lower box is provided with sewage draining exit, and sewage draining exit is provided with valve; The side of described upper box is provided with delivery port; Described dividing plate is provided with several holes and bracing frame, a corresponding hole of bracing frame, one end of bracing frame is fixed on the hole on dividing plate, and the other end is arranged in lower box; Each bracing frame overlaps a filter bag.
In technique scheme, support frame as described above is hollow structure.
In technique scheme, described in be supported for cage structure.
In technique scheme, described filter bag is fibrofelt filter bag.
Compared with prior art, the beneficial effects of the utility model are:
1) concentration of the suspended material SS in sewage can significantly reduce, and the suspended material SS concentration in purifying waste water can lower than 5mg/L, and suspended material particle diameter is lower than 1 micron.Meet the standard of sewage discharge and reuse;
2) the utility model High-efficiency sewage filter can not be subject to processing water quantitative limitation, and the process water yield is changeable.Install the fibrofelt filter bag of varying number according to the process water yield, design meets raw water box and the filtered water tank of the process water yield;
3) loss of flood peak of fibrofelt filter bag is little, and a raw water inlet place demand fulfillment overcomes the hydrostatic pressing of delivery port and the filter bag loss of flood peak can keep continuous operation, and operating cost is low;
4) filter bag automatic back-flushing function.The utility model High-efficiency sewage filter achieves continuous operation in unmanned situation and filter bag automatic back-flushing function.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model structure;
Wherein: 1 be casing, 2 are water inlets, 3 is lower boxes, 4 is that to cover filter bag, 5 are bracing frames, 6 to fibrofelt are sewage draining exits, 7 are dividing plates, 8 are upper boxes, 9 are delivery ports, 10 is blowoff valves.
Detailed description of the invention
As shown in Figure 1, the utility model is a seal case, by horizontally set one piece of dividing plate, casing is divided into upper box and lower box in casing, two casings are alone seal case, the side of upper box is provided with delivery port, the side of lower box is provided with water inlet, the bottom surface of lower box is provided with sewage draining exit simultaneously, sewage draining exit arranges blowoff valve.Dividing plate is provided with several through holes, each through hole is arranged a bracing frame, bracing frame is cage structure; Bracing frame and dividing plate keep vertical relation, and one end is fixed on the through hole of dividing plate, and remainder is arranged in lower box.Each bracing frame overlaps a filter bag, and sack and the through hole of filter bag realize seamless link, make between upper box and lower box completely isolated by filter bag.
When starting working, the blowoff valve of sewage draining exit closes, a large amount of sewage flows to lower box from water inlet, is filled up by lower box rapidly, hydraulic pressure make sewage by filter bag tightly be pressed on bracing frame, because filter bag is fibrofelt filter bag, water can only be allowed to pass through, and the water therefore in sewage enters in bracing frame through filter bag, and a large amount of water enters upper box by bracing frame, can be overflowed by delivery port after the water in upper box is full, the discharge water after the water of spilling is and is cleaned filtration.The outer surface that suspension in sewage is then blocked in filter bag is stayed in lower box.
When after lower box work a period of time, make to affect during the mud overheap in lower box water permeation when crossing filter bag, just opened by blowoff valve, a large amount of mud will discharge lower box together along with sewage, then closes blowoff valve, and lower box works on.
When long work, can cause more foreign material piled up by filter bag, therefore, cleaning is needed to worry too much bag, only need will purify waste water from the delivery port of casing to pouring into casing during cleaning, a large amount of water will flow into from upper box, then penetrates into lower box through filter bag.In the process the mud be attached on the filter bag of lower box side is washed out, and discharge from sewage draining exit with sewage.Thus reach the object of clear filter bag, and do not need to take off separately clear.
In superincumbent cleaning process, sewage draining valve can carry out automatic controlling system, after whole system runs a period of time, open sewage draining valve, in lower box, mud is excluded, and the clear water simultaneously in upper box to lower box, achieves the automatic cleaning process of filter bag with regard to reverse flow.
All features disclosed in this description, except mutually exclusive feature, all can combine by any way.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
