Description

But super large flow filter core of backwash

Technical Field

The utility model relates to a but super large flow filter core of backwash.

Background

At present, domestic and foreign micropore folding filter elements are designed according to a deep layer filtering mode, and filter membranes are in a compact arrangement structure no matter what folding mode is adopted; and the filter membrane is at least a composite membrane with more than three layers, namely, the inner layer and the outer layer are respectively non-woven fabrics, the middle layer is a microporous membrane, after the filter core structure is used for a long time, tiny pollutants enter the multi-layer structure of the filter core and then gradually agglomerate together, the pollutants can not be removed through normal backwashing, the pollution of the filter membrane is irreversible, and the filter core can only be scrapped after the pollution is serious, so that the great waste is caused.

There are many water purification cartridges for water filtration in the prior art, but these cartridges are generally non-replaceable, non-backwashable, disposable cartridges, such as the well-known cylindrical, solvent-jet PP cartridges, microporous ceramic cartridges, which have been commonly used in cartridge filter devices, but which are disposable and cannot be backwashed and cleaned before use.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at not enough in the prior art, provide a but super large flow filter core of backwash, through single opening and by outer and interior rivers direction design, save the renew cartridge time by a wide margin, reduce the filter vat size, reduce factory building and filter vat investment cost.

The technical scheme is as follows: in order to achieve the above object, the utility model provides a but super large flow filter core of backwash, its characterized in that: the filter membrane fixing device is characterized by comprising a filter membrane, a supporting cylinder and an upper end cover, wherein the filter membrane is sleeved on the outer wall of the supporting cylinder, the upper end cover is fixedly connected with the upper end face of the supporting cylinder, the lower end face of the supporting cylinder is an opening, the sealing ring is arranged between the lower end cover and the upper end face of the supporting cylinder, the plastic shell is arranged on the outer wall of the supporting cylinder, and the filter membrane is positioned between the plastic shell and the supporting cylinder.

As an improvement of the scheme, the filter element is provided with filter holes, and the aperture of each filter hole is 1 mu m, 5 mu m, 6 mu m, 20 mu m, 25 mu m, 50 mu m and 75 mu m.

As an improvement of the scheme, the inner diameter of the supporting cylinder is 3mm, and the outer diameter of the supporting cylinder is 6 mm.

Compared with the prior art the utility model discloses the beneficial effect who has: the utility model discloses simple structure, convenient to use height receive dirty volume, long-life and low cost, the pollutant does not remain when guaranteeing the renew cartridge, through single opening and by interior and outer rivers direction design, the pollutant does not remain when guaranteeing the renew cartridge.

List of reference numerals: 1. plastic shells; 2. a lower end cover; 3. a support cylinder; 4. a water inlet; 5. filtering the membrane; 6. and (5) sealing rings.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

A backwashable ultra-high flow filter element as shown in fig. 1-2, which is characterized in that: the water inlet device comprises a filter membrane 5, a supporting cylinder 3 and an upper end cover, wherein the filter membrane 5 is sleeved on the outer wall of the supporting cylinder 3, the upper end cover is fixedly connected with the upper end face of the supporting cylinder 3, and the lower end face of the supporting cylinder 3 is a water inlet 4.

The sealing ring 6 is arranged between the lower end cover 2 and the upper end surface of the supporting cylinder 3; the filter element is provided with filter holes, and the aperture of each filter hole is 1 mu m, 5 mu m, 6 mu m, 20 mu m, 25 mu m, 50 mu m and 75 mu m; the filter membrane filtration device is characterized by further comprising a plastic shell 1, wherein the plastic shell 1 is installed on the outer wall of the support cylinder 3, and the filter membrane 5 is located between the plastic shell 1 and the support cylinder 3; the internal diameter of the support cylinder 3 is 3mm, and the external diameter of the support cylinder 3 is 6 mm.

The utility model discloses a theory of operation: with the raw water through the opening input to a support section of thick bamboo 3 on the support section of thick bamboo 3, because the other end of a support section of thick bamboo 3 seals fixedly through the upper end cover, along with the water yield increase in the support section of thick bamboo 3, cup joint the filter membrane 5 at its outer wall and can filter the water of 3 inside supports, water outflow support section of thick bamboo 3 after filtering, impurity after filtering is stayed in the support section of thick bamboo 3, the space in the support section of thick bamboo 3 is great, make it have bigger dirt volume of receiving, it need not often clean, when the dirt in the support section of thick bamboo 3 is cleared up to needs, dismantle flow filter core wholly, wash the inner wall of a support section of thick bamboo 3, after taking out the dirt, can realize repetitious usage, it is.

Removal rate and flow rate differential pressure:

the technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features.
