Abstract

The utility model discloses a large-flow-capacity filter which comprises a water inlet manifold, a water outlet manifold and at least two filtering units, wherein the water inlets of the filtering units are connected to the water inlet manifold after being connected in parallel, and the water outlets of the filtering units are connected to the water outlet manifold after being connected in parallel. In the utility model, the water inlets of a plurality of filtering units are connected to the water inlet manifold after being connected in parallel, and the water outlets of the plurality of filtering units are connected to the water outlet manifold after being connected in parallel. In this way, the volume of a manifold is very small when the water inlets and the water outlets of the filtering units are connected to one manifold in parallel, and in addition, the size of a filter case is not necessary to be too large, and only one filter element is mounted in each filter case to meet the requirement of large flow capacity; the filtering units are simple in structure and convenient in disassembly; and the flow capacity can be randomly adjusted according to the requirements. The utility model adopts simple structure to realize large-flow-capacity filtration, thereby greatly reducing the cost.

Description

A kind of big flow filter

[technical field]

The utility model relates to water treatment product, relates in particular to a kind of big flow filter.

[technical background]

Filtration is an important step in the water treatment technology.All need the filter of big flux (big flow) to filter in fields such as desalinizations.

Present big flow filter all is to consider in the shell at one to adorn many filter cores, to form bigger flow.This structure need be accomplished the volume of considering shell very big, and many filter cores to consider in the shell assembling and dismounting at one all very inconvenient, more can not make cross-current type structure with backwashing function.For satisfying the requirement of bigger flow, generally need in a worry shell, prop up filter core by dress 50-60, structure is very complicated.Therefore, consider the big flow filter complex structure not only of adorning many filter cores in the shell for this one, and assembling and dismounting are inconvenient, use dumb.

Require each parts in the whole system all to have decay resistance preferably in the seawater desalination system.Therefore the worry shell that adopts stainless steel material is the cost height not only, and is corroded easily, therefore, requires to consider shell in the seawater desalination system and preferably adopts corrosion resistant plastic material.And the dismounting to many filter cores is inconvenient more in the plastic material, and technology is complicated more, and currently used plastics are considered generally can only be with the filter core of about 5 in fashionable dress in the shell, and Duo words will increase the dismounting difficulty greatly again, influence properties of product.

[summary of the invention]

The purpose of this utility model is exactly in order to solve problems of the prior art, proposes a kind of big flow filter, can realize big traffic filtering with simple structure.

For achieving the above object, the utility model patent has proposed a kind of big flow filter, comprise water inlet manifold, outfall sewer, at least two filter elements, be connected to water inlet manifold after the water inlet parallel connection of described filter element, be connected to outfall sewer after the delivery port parallel connection of filter element.

As preferably, described filter element comprises filter core and considers shell that a filter core is installed in the described worry shell, and the two ends of considering shell are respectively water inlet and delivery port.

As preferably, described filter core comprises top sub, filter course, bottom fitting, guard protective layer, and described filter course is columniform collapsible corrugated, and two ends are connected with top sub and bottom fitting respectively, and the outer setting of filter course has the guard protective layer.

As preferably, the mesh on the described guard protective layer becomes cellular.

As preferably, also be provided with sealing ring on the described top sub.

As preferably, described top sub and bottom fitting are made by polypropylene material, and filter course is made by the polyester material.

The beneficial effect of the utility model patent: be connected to water inlet manifold after the water inlet parallel connection of the utility model with a plurality of filter elements, be connected to outfall sewer after the delivery port parallel connection of a plurality of filter elements.Upward house steward's volume is very little later on to be parallel to a house steward like this, and the worry shell does not need very big yet, and each is considered only needs 1 filter core of installation just can satisfy the requirement of big flow in shell, and the structure of filter element is very simple, easy accessibility, and flow can be adjusted arbitrarily as required.Adopt simple structure to realize big traffic filtering, and cost reduce greatly.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.

[specific embodiment]

Consult Fig. 1,2,3, a kind of big flow filter, comprise water inlet manifold 1, outfall sewer 2, at least two filter elements 3, be connected to water inlet manifold 1 after water inlet 31 parallel connections of described filter element 3, be connected to outfall sewer 2 after delivery port 32 parallel connections of filter element 3.During filtration, current enter from water inlet manifold 1, and flow into each filter element 3 respectively, and the current in each filter element 3 are flowed to outfall sewer 2 again and flow out, and realize big traffic filtering.The quantity of filter element 3 can suitably be adjusted as required, and the quantity of filter element 3 flow of multi-filter more is big more, and the size of water inlet manifold 1, outfall sewer 2 is also wanted corresponding increase.

Consult Fig. 4, described filter element 3 comprises filter core 33 and considers shell 34 that a filter core 33 is installed in the described worry shell 34, and the two ends of considering shell 34 are respectively water inlet 31 and delivery port 32.

Consult Fig. 5; described filter core 33 comprises top sub 331, filter course 332, bottom fitting 333, guard protective layer 334; described filter course 332 is columniform collapsible corrugated; two ends are connected with top sub 331 and bottom fitting 333 respectively, and the outer setting of filter course 332 has guard protective layer 334.Mesh on the described guard protective layer 334 becomes cellular.Also be provided with sealing ring 335 on the described top sub 331.Described top sub 331 and bottom fitting 333 are made by polypropylene material, and filter course 332 is made by the polyester material.This folding type filter element can adopt the inner pressed structure, and promptly the liquid being filtered flow direction is by outward interior, and the inner chamber at filter course 332 does not just need very fine and close skeleton to support like this, simplifies the structure, and has reduced cost yet.The superficies of filter course 332 are long-pending to be several times of inner layer sheet area, has also satisfied the big flux requirement of filter core preferably.Guard protective layer 334 is simple in structure, easy to process, and intensity is higher than gauze and spraying plastics.The filter core two ends of the utility model inner pressed all are through holes, do not need to resemble to adopt an end to be designed to dead end the external-compression type, therefore, have cross flow effects, can carry out backwash to filter core easily.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
