Abstract
The utility model relates to a centrifugal self-cleaning filter which comprises a filter body (1), a centrifugal filtering element (2), a backflushing sewage discharge device (3) and an instrument control unit (4), wherein the centrifugal element (2) and the backflushing sewage discharge device (3) are both positioned in the filter body (1), the backflushing sewage discharged device (3) is arranged on the outer side of the cylindrical wall of the centrifugal filtering element (2), the instrument control unit (4) is arranged on the outer wall of the filter body (1), and the filter body (1) and the centrifugal filtering element (2) are both made of special metal. According to the invention, the centrifugal filtering element and the mechanical removing type backflushing sewage discharge device overcome the defects that screen filters are not thorough in backflushing and short in service life, and as a special material is adopted, the filter can run for a long term in a seawater medium.
Description
Technical field
The present invention relates to a kind of self-cleaning strainer, especially service life high, can be at the filter of the medium-term and long-term operation of seawater medium, specifically a kind of centrifugal self-cleaning filter.
Background technology
Self-cleaning strainer is claimed the through type piping filter again, is widely used in the water treatment system of industry-by-industry.
In general, present self-cleaning strainer is that fixedly filter net type, filter unit are mainly braiding filter screen, wedge filter screen mostly, and this type filter is prone to following problem at present:
1, this type filter is owing to limited by filter screen, and treating capacity is limited;
When 2, this type filter adapts to the influent quality variation, the backwash weak effect;
3, general 316 or 304 materials that adopt of this filter are made, and are difficult to adapt to nuclear power and seawater corrosion, and service life is shorter, is prone to accident, jeopardizes the operation of whole water treatment system.
Summary of the invention
The objective of the invention is short to limited, life-span of the existing treating capacity of existing self-cleaning strainer, can not be in the problem of the medium-term and long-term operation of seawater medium, propose a kind of service life high, can be at the centrifugal self-cleaning filter of the medium-term and long-term operation of seawater medium.
Technical scheme of the present invention is:
A kind of centrifugal self-cleaning filter; It comprises filter body, centrifugal filter unit, backwash blowdown apparatus and instrument control module; Described centrifugal filter unit and backwash blowdown apparatus all are positioned at filter body; The backwash blowdown apparatus is installed in the barrel outside of centrifugal filter unit, and the instrument control module is installed on the outer wall of filter body, and described filter body and centrifugal filter unit are super-duplex stainless steel.
Instrument control module of the present invention comprises automatic program control, the first differential pressure detecting sensor of filter and transmitter.
Beneficial effect of the present invention:
It is not thorough that the present invention has overcome the well strainer backwash through centrifugal filter unit and mechanical removal formula backwash blowdown apparatus, and the shortcoming that service life is low adopts extraordinary material, and filter can be moved in the seawater medium midium or long term.
Description of drawings
Fig. 1 is one of structural representation of the present invention.
Fig. 2 is a structure for amplifying sketch map of the present invention.。
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Shown in Fig. 1-3; A kind of centrifugal self-cleaning filter; It comprises filter body 1, centrifugal filter unit 2, backwash blowdown apparatus 3 and instrument control module 4, it is characterized in that described centrifugal filter unit 2 and backwash blowdown apparatus 3 all are positioned at filter body 1, and backwash blowdown apparatus 3 is installed in the barrel outside of centrifugal filter first 2; Be to clean the device that filter unit back dirt is discharged automatically; Instrument control module 4 is installed on the outer wall of filter body 1, and described filter body 1 is the specialty metal super-duplex stainless steel with centrifugal filter unit 2, can be medium-term and long-term operation of the Korrosionsmedium that contains the CC ion (like seawater etc.).
Centrifugal filter first 2 of the present invention is that centrifugal rotation filter is first, extraordinary material manufacturing.Filtering backwash, produce centrifugal force by driving machine, auxiliary backwash.
Instrument control module 4 of the present invention comprises automatic program control, the first differential pressure detecting sensor of filter and transmitter, and the waterpower in the filter running, flow are detected, and accomplishes processes such as filter operation, cleaning automatically.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
Claims (2)
