Abstract
The utility model discloses a milipore filter subassembly that is favorable to back flush, including the barrel, set up milipore filter subassembly body in the barrel, it has a plurality of wash ports to correspond the distribution of milipore filter subassembly body on the upper end cover of barrel, and it has back flush inlet port, its characterized in that to correspond the distribution of milipore filter subassembly body on the bottom end cover: the centre of the lateral wall of barrel is round ring packing portion, it has a plurality of inlet openings of going up to distribute on the lateral wall of the barrel of ring packing portion top, it has a plurality of inlet openings down also to distribute on the lateral wall of the barrel of ring packing troops under one's command side, go up the big or small the same of inlet opening and inlet opening down, the number of inlet opening only is fourth to the half of the number of inlet opening under and. The utility model relates to a rationally, simple structure, the equipment investment is few, improves back flush efficiency, and the backwashing effect on milipore filter subassembly upper portion is better.
Description
Technical field
This utility model relates to a kind of hyperfiltration membrane assembly, particularly to a kind of hyperfiltration membrane assembly being conducive to backwash.
Background technology
Existing rural area integrated ultrafiltration membrane water treatment device includes the mixing pit, ultra-filtration membrane device and the clear water reserviors that are connected by pipeline. Former water is extracted into mixing pit, is subsequently adding coagulant, installs agitator, coagulant and Yuan Shui are stirred with agitator, then the medicament in mixing pit and water are extracted into ultra-filtration membrane device process in mixing pit, and the water purification after having processed removes clear water reserviors.
Existing hyperfiltration membrane assembly includes cylinder, in cylinder (1), hyperfiltration membrane assembly body is set, hyperfiltration membrane assembly body is made up of some cannulated ultrafilter membranes, on the upper end cover of described cylinder (1), corresponding hyperfiltration membrane assembly body distribution has some osculums (the corresponding cannulated ultrafilter membrane of each osculum), on bottom end cover, corresponding hyperfiltration membrane assembly body distribution has backwash air inlet, this is prior art, does not repeat at this. Being evenly distributed with some inlet openings on the sidewall of cylinder, inlet opening can be longitudinal arrangement. When with gas hyperfiltration membrane assembly body being carried out backwash (gas enters in the middle of the ultrafilter membrane of cannulated from bottom), owing to air-flow can not effectively arrive the top of hyperfiltration membrane assembly body, (air-flow has just gone out hyperfiltration membrane assembly body when bottom, then discharge from inlet opening), causing that the backwash effect on top is poor, backwash efficiency is low.
Utility model content
For existing problem, the purpose of this utility model is in that the hyperfiltration membrane assembly being conducive to backwash providing a kind of backwash effect good.
To achieve these goals, the technical solution of the utility model is: a kind of hyperfiltration membrane assembly being conducive to backwash, including cylinder, hyperfiltration membrane assembly body is set in cylinder, on the upper end cover of described cylinder, corresponding hyperfiltration membrane assembly body distribution has some osculums, on bottom end cover, corresponding hyperfiltration membrane assembly body distribution has backwash air inlet, it is characterized in that: the centre of the sidewall of described cylinder is a circle annular seal, on the sidewall of the cylinder above described annular seal, distribution has some upper inlet openings, on the sidewall of the cylinder below described annular seal, also distribution has some lower inlet openings, described upper inlet opening is identical with the size of lower inlet opening, and the number of lower inlet opening be only inlet opening number 1/1 to two/4ths.
Adopt such scheme, the number of lower inlet opening reduces, not affecting water inlet, but but mean when backwash, the steam vent of bottom reduces, so, air-flow is conducive to enter into the top of hyperfiltration membrane assembly body, it is achieved the backwash to top, after so improving, the backwash effect on top improves, and backwash efficiency improves 50%.
In such scheme: 1/2nd of the number that number is upper inlet opening of described lower inlet opening. Good backwash effect can be reached.
In such scheme, on the sidewall of the cylinder above described annular seal, distribution has the upper inlet opening of number row's longitudinal arrangement, on the sidewall of the cylinder below described annular seal, distribution has the lower inlet opening of number row's longitudinal arrangement, the half of the draining that row is upper inlet opening of described lower inlet opening. By upper inlet opening and lower inlet opening longitudinal arrangement, it appears more attractive.
The beneficial effects of the utility model are: this utility model is reasonable in design, simple in construction, and equipment investment is few, improve backwash efficiency, and the backwash effect on hyperfiltration membrane assembly top is better.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described:
Relative position in the nouns of locality such as front, back, left, right, up, down of the present utility model only representative graph, does not indicate that the absolute position of product.
Embodiment 1
As it is shown in figure 1, the hyperfiltration membrane assembly being conducive to backwash of the present utility model is made up of parts such as cylinder 1, annular seal 2, upper inlet opening 3, lower inlet openings 4.
Arranging hyperfiltration membrane assembly body in cylinder 1, on the upper end cover of cylinder 1, corresponding hyperfiltration membrane assembly body distribution has some osculums, and on bottom end cover, corresponding hyperfiltration membrane assembly body distribution has backwash air inlet, and this is prior art, does not repeat at this.
The centre of the sidewall of cylinder 1 is a circle annular seal 2, the sidewall of the cylinder 1 above annular seal 2 is identical with the length of the sidewall of the cylinder 1 of lower section, on the sidewall of the cylinder 1 above annular seal 2, distribution has some upper inlet openings 3, on the sidewall of the cylinder 1 below annular seal 2, also distribution has some lower inlet openings 4, upper inlet opening 3 and lower inlet opening 4 are bar hole, upper inlet opening 3 is identical with the size of lower inlet opening 4, and the number of lower inlet opening 4 be only inlet opening 3 number 1/1 to two/4ths. It is preferably 1/2nd.
Watch more neatly so that cylinder 1 is outer, more attractive. We select: on the sidewall of the cylinder 1 above annular seal 2, distribution has the upper inlet opening 3 of number row's longitudinal arrangement, on the sidewall of the cylinder 1 below annular seal 2, distribution has the lower inlet opening 4 of number row's longitudinal arrangement, and the row of lower inlet opening 4 is the half of the draining of upper inlet opening 3.
This utility model is not limited to above-described embodiment, it will be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work. Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in the protection domain being defined in the patent claims.
