Abstract

A kind of modified filter, upper layer and lower layer filter bag (3,6) are installed in tank body (10), water inlet pipe (5) in upper layer filter bag (3) connection, lower layer's filter bag (6) connects lower water inlet pipe (2), upper water inlet pipe connects external plumbing drain by water inlet (8), and upper and lower water inlet pipe (5,2) is connected by connecting tube (9), and tank body (10) upper end has oil discharge outlet (7), lower end has water outlet (11), is placed with molecular modification coalescence material filter core in the filter bag (3,6).Its advantage is that structure is simple, easy access and maintenance.Filter bag filter core uses molecular modification coalescence material, has filtering, coalescence and suction-operated, is convenient for regeneration treatment, can Reusability.

Description

A kind of modified filter

Technical field

The utility model relates to the separation of immiscible liquid, it is related to that the filtering of filtering material is housed in a closed container Device, espespecially a kind of modified filter.

Background technique

Currently, the processing oil-containing quarrel higher sewage of ingredient in domestic city is still without suitable device, prior art portion big absolutely Separating device is made of water-oil separating and filter device.Oily-water seperating equipment combines waste-oil scavenger, filtering dress using natural subsidence It sets using walnut shell, quartz sand and glauconite filter.These existing processing units are found to ask there are following in use Topic: firstly, in order to guarantee that sewage treatment can reach standard, needing to add a large amount of efficient demulsifying flocculants in treatment process, System after processing is caused to generate a large amount of drosses；Secondly, water viscosity increases in sewage, greasy dirt and filtrate binding force is caused to increase, For lightweight shell filtrate, relative density is further decreased, and is easy to cause backwash filtrate expansion excessively high, is built the pressure, is run and expect to ask Topic is serious, and for heavy filter material, it is easy to form one layer of gluey hardening layer on filtrate surface layer in filter process, it is non-breakable, it makes Decline at backwash effect, it is difficult to realize the thorough regeneration of filtrate；It again, is that added amount of chemical is big, operating cost is high, produces simultaneously Raw a large amount of drosses, and mature technology is had no at present for the processing of dross.In conclusion existing urban sewage treating device When handling the oil-containing quarrel higher sewage of ingredient, that there are oil removal efficiencies is not high, dross yield is excessive and internal filtrate is difficult The problem of to regenerate.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of modified filters, it is intended to will contain Oil-solids, while the oily wastewater again containing dispersion oils are completed at the same time screening filtering and dispersion oils by an equipment Coalescence, make water outlet the primary processing up to standard in equipment of oil and suspended matter.

The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of modified filter, including tank Body, it is characterised in that: upper layer and lower layer filter bag is equipped in tank body, upper layer filter bag connects upper water inlet pipe, under the connection of lower layer's filter bag Water inlet pipe, upper water inlet pipe connect external plumbing drain by water inlet, and upper and lower water inlet pipe is interconnected by connecting tube, tank body There is oil discharge outlet in upper end, and there is water outlet in lower end, and molecular modification coalescence material filter core is placed in the filter bag.

Molecular modification coalescence material is novel nano active material, is led in electronics industry, biological medicine, environmental protection, optics etc. The application in domain all shows its tremendous potential.

Compared with the existing technology compared with the beneficial effects of the utility model are: structure is simple, easy access and maintenance.Filter bag Filter core uses molecular modification coalescence material, has filtering, coalescence and suction-operated, can Reusability convenient for regeneration treatment.

Detailed description of the invention

Fig. 1 is the structure perspective diagram of the utility model.

Fig. 2 is the left view schematic diagram of Fig. 1.

Fig. 3 is the schematic diagram in top down perspective of Fig. 1.

In figure: 1 be supporting leg, 2 be lower water inlet pipe, 3 be filter bag, 5 be upper water inlet pipe, 6 be filter core, 7 be oil discharge outlet, 8 for into The mouth of a river, 9 be connecting tube, 10 be tank body, 11 be water outlet.

Specific embodiment

The utility model will be further described with reference to the accompanying drawing.

Referring to attached drawing 1, a kind of modified filter of the utility model, including tank body 10, upper and lower two are equipped in tank body 10 Layer filter bag 3,6, upper layer filter bag 3 connect upper water inlet pipe 5, and lower layer's filter bag 6 connects lower water inlet pipe 2, and upper water inlet pipe is connected by water inlet 8 External plumbing drain is connect, upper and lower water inlet pipe 5,2 is connected by connecting tube 9, and there is oil discharge outlet 7 in 10 upper end of tank body, and there is water outlet in lower end 11, molecular modification coalescence material filter core is placed in the filter bag 3,6.

When use: sewage to be processed enters upper water inlet pipe 5 from water inlet 8, while the sewage in water inlet pipe 5 is through connecting tube 9 are input to lower water inlet pipe 2, and the sewage in upper and lower two water inlet pipe is through being placed with the mistake of filter bag 3 and 6 of molecular modification coalescence material filter core Enter tank body 10 after filter, the greasy dirt of lightweight is discharged from the oil discharge outlet 7 on top, and the water of heavy is flowed out through water outlet 11.

Claims

1. a kind of modified filter, including tank body (10), it is characterised in that: be equipped with upper layer and lower layer filter bag in tank body (10) (3,6), water inlet pipe (5) in upper layer filter bag (3) connection, lower layer's filter bag (6) connect lower water inlet pipe (2), upper water inlet pipe (5) by into The mouth of a river (8) connects external plumbing drain, and upper and lower water inlet pipe (5,2) is connected by connecting tube (9)；There is oil discharge outlet in tank body (10) upper end (7), lower end has water outlet (11), is placed with molecular modification coalescence material filter core in the filter bag (3,6).
