The present invention will be described in more detail below with reference to the drawings. In the drawings, like component numbers are used for components having substantially the same function, such as component numbers 100, 100a, 100b, 100c shown in fig. 1, 4, 5, and 7.
Fig. 1 to 3 illustrate a first embodiment of the present invention, in which the structure and connection relationship of the membrane filter assembly 1, the backwash support pipe 2, the first water spraying structure 3 and the backwash pump 4 of the filter structure 100 of the present invention are illustrated. As shown in fig. 1 to 3, the filter structure 100 of the present invention includes:
a membrane filtration module 1 having a plurality of micro-pores, being tubular, having a first end 11, a second end 12 and a first space 13; the first end 11 of the membrane filtration module is provided with a closing plate 14; the second end 12 of the membrane filtration module 1 has a first opening 15; and
a backwash support pipe 2 having a first end 21 and a second end 22, the first end 21 of the backwash support pipe being rotatably pivoted on the closing plate 14; and
at least one first water spraying structure 3, which is composed of a first communication pipe 31 and a first water spraying pipe 32; the first communication pipe 31 is communicated with the back washing supporting pipe 2 and the first water spraying pipe 32, and the first water spraying pipe 32 is arranged at the position close to the membrane filtering component 1; the first water jet pipe 32 has a plurality of first water jet ports 321 (shown in fig. 2) on the pipe wall facing the membrane filter assembly 1; and
a back washing pump 4 having a first water inlet pipe 41 and a first water outlet pipe 42, the first water outlet pipe 42 being connected to the back washing support pipe 2 for injecting pressurized water, so that the pressurized water is sprayed from the first water spraying port 321 of the first water spraying pipe 32; by the structure, the purposes of filtering and backwashing simultaneously and continuously can be achieved. As will be described in detail below.
The membrane filter element 1 has a plurality of pores and is tubular, having a first end 11, a second end 12 and a first space 13. The pore diameter of the micropores of the membrane filtration module 1 may be (but is not limited to) 3 to 30 micrometers (μm), and various materials applicable to membrane filtration, such as stainless steel, may be used.
As shown in fig. 3, after the membrane filtration module 1 is inserted into the raw water 101, the membrane filtration module 1 can filter the raw water to form a separation liquid that can pass through the membrane filtration module and a sludge that cannot pass through the membrane filtration module, and the separation liquid enters the first space 13 of the membrane filtration module 1.
As shown in fig. 1, the first end 11 of the membrane filtration module 1 is provided with a closing plate 14 for closing the first end 11 of the membrane filtration module 1. The second end 12 of the membrane filtration module 1 has a first opening 15 for facilitating drainage of the separated liquid in the first space 13 of the membrane filtration module 1.
The backwash support pipe 2 has a first end 21 and a second end 22, and is mainly used for connecting the first water spraying structure 3 and the backwash pump 4. The first end of the back-washing supporting pipe 2 is rotatably pivoted on the closing plate 14, which can conveniently drive the first water spraying structure 3 to rotate, so that the first water spraying structure 3 can perform comprehensive back washing inside the membrane filtering component 1.
A first support bearing 16 may be provided on the closing plate 14 for pivoting a first end 21 of the backwash support pipe 2.
As shown in fig. 1-2, the first water spraying structure 3 is composed of a first communicating pipe 31 and a first water spraying pipe 32; the first communication pipe 31 is communicated with the back washing support pipe 2 and the first water spraying pipe 32, and the first water spraying pipe 32 is arranged at a position close to the membrane filtering component 1; the first water jet pipe 32 has a plurality of first water jet ports 321 on the pipe wall facing the membrane filtration module 1 for performing back flushing from the inside of the membrane filtration module 1. The first water spraying pipe 32 can be as close as possible to the membrane filtration module 1 to reduce power loss and increase the backwashing efficiency.
The back washing pump 4 has a first water inlet pipe 41 and a first water outlet pipe 42, and the first water outlet pipe 42 is connected to the back washing support pipe 2 for injecting pressurized water, so that the pressurized water is sprayed from the first water spraying port 321 of the first water spraying pipe 32. The backwashing using the first water spray pipe 32 affects only a part of the filtering function of the membrane filtering unit (as shown in fig. 2), so that the filtering and the backwashing can be simultaneously and continuously performed.
The first water inlet pipe 41 may be connected to a back flush water source (not shown). In addition, the first water inlet pipe 41 can also be directly communicated with the first space 13 of the membrane filter assembly 1; in this case, the backwash pump 4 is started after sufficient separation liquid has been present in the first space 13 of the membrane filtration module 1, and the separation liquid can be withdrawn for backwash, thereby eliminating the cost of an additional source of backwash water.
As shown in fig. 2, the water spraying direction of the first water spraying port 321 of the first water spraying pipe 32 may be substantially parallel to the diameter direction of the membrane filter assembly 1, thereby efficiently backwashing the membrane filter assembly 1. In addition, at least one second water spraying structure 5 can be further arranged on the back washing support pipe 2. The second water spraying structure 5 is composed of a second communicating pipe 51 and a second water spraying pipe 52; the second communicating pipe 51 communicates the backwash support pipe 2 and the second water spraying pipe 52; the wall of the second water spraying pipe 52 is provided with a plurality of second water spraying nozzles 521. The water spraying direction of the second water spraying opening 521 of the second water spraying pipe 52 can be substantially parallel to the tangential direction of the membrane filter assembly 1, so as to drive the backwashing support pipe 2 to rotate when spraying water, thereby achieving the purpose of saving the cost of the structure for arranging other rotating backwashing support pipes. At least one first water spraying structure 3 and at least one second water spraying structure 5, for example, six first water spraying structures 3 and two second water spraying structures 5, may be disposed on the backwashing support pipe 2 to improve the backwashing efficiency.
After the second water spraying structure 5 is provided, the backwash support pipe 2 is driven to rotate, so that a rotatable anti-leakage joint 23 can be provided at the connection between the second end 22 of the backwash support pipe 2 and the first water outlet pipe 42 of the backwash pump 4, as shown in fig. 1.
In the case where the first and second water spray pipes 32 and 52 have a predetermined length, more than one support rod 24 may be respectively provided between the first and second water spray pipes 32 and 52 and the backwash support pipe 2, thereby increasing the strength.
Fig. 4 shows a second embodiment of the present invention, in which an embodiment in which the filtering structure 100a, the membrane filtering unit 1a, the backwash support pipe 2a, the first water spraying structure 3a, and the backwash pump 4a are applied to the submersible filtering apparatus 200a is illustrated. As shown in fig. 4, the submersible filter device 200a includes the filter structure 100a described above, and further includes: a cover plate 61a disposed at the first opening 15a of the membrane filtration module 1 a; and a water pump 62a having a second water inlet pipe 621a and a second water outlet pipe 622 a; the second inlet pipe 621a communicates with the first space 13a of the membrane filtration module 1 a; by the structure, the purposes of filtering and backwashing simultaneously and continuously can be achieved.
The cover plate 61a is disposed at the first opening 15a of the membrane filtration module 1a, and prevents the separated liquid entering the first space 13a of the membrane filtration module 1a from accidentally overflowing. In addition, a second supporting bearing 63a may be disposed on the cover sealing plate 61a for pivotally mounting the upper section of the backwashing supporting tube 2 a.
The water pump 62a has a second inlet pipe 621a and a second outlet pipe 622 a; the second water inlet pipe 621a is communicated with the first space 13a of the membrane filtration module 1a, so that the water pump 62a can conveniently pump the separated liquid from the first space 13a of the membrane filtration module 1 a.
In the second embodiment, both the backwash pump 4a and the suction pump 62a may be submerged pumps, so as to facilitate the entire submersible filtration device 200a to sink into raw water, such as stream water; with this configuration, even when the stream is too turbid, for example, the separated liquid can be easily obtained, thereby reducing the burden on the subsequent treatment apparatus and eliminating the cost for treating the sludge that cannot pass through the membrane filtration module 1 a.
Fig. 5 to 6 show a third embodiment of the present invention, in which an embodiment in which the filtering structure 100b, the membrane filtering unit 1b, the backwashing support pipe 2b, the first water spraying structure 3b, and the backwashing pump 4b are applied to the vertical filtering apparatus 300b is illustrated. As shown in fig. 5 to 6, the vertical filter device 300b includes the filter structure 100b described above, and further includes: a vertical storage tank 71b, wherein a partition plate 72b is provided inside the vertical storage tank 71b to form an upper space 73b and a lower space 74 b; the isolation plate 72b has a second opening 721 b; the membrane filtration module 1b is arranged at the bottom of the partition plate 72b, and the first opening 15b of the membrane filtration module 1b is communicated with the second opening 721b of the partition plate 72 b; and a raw water supply structure 75b communicating with the lower space 74b of the vertical storage tank 71 b; and a drainage structure 76b communicating with the upper space 73b of the vertical reserve tank 71 b; by the structure, the purposes of filtering and backwashing simultaneously and continuously can be achieved.
The raw water supply structure 75b allows raw water to be injected into the lower space 74b of the vertical storage tank 71 b. Depending on the usage, the raw water supply structure 75b may be provided with a pressure pump or may be configured to use a level difference (not shown) to inject the pressurized raw water into the lower space 74b of the vertical storage tank 71b, thereby increasing the efficiency of raw water filtration, generating power to flow the separated liquid into the upper space 73b of the vertical storage tank 71b, and facilitating the discharge of the separated liquid from the drainage structure 76 b; in this case, the sludge is gradually accumulated in the lower space 74b of the vertical storage tank 71b and gradually settled downward. A drain pipe 77b may be provided at the bottom of the vertical storage tank 71b to facilitate the removal of sludge.
The vertical storage tank 71b may have a cylindrical structure. In addition, the raw water supply structure 75b can communicate with the lower space 74b of the vertical storage tank 71b along the tangential direction of the vertical storage tank 71b (as shown in fig. 6), and inject raw water, thereby generating the effect of vortex sand settling. In addition, a supporting seat 722b and a second supporting bearing 723b are disposed around the second opening 721b of the isolation plate 72b for pivotally installing the upper section of the backwashing supporting pipe 2 b.
As shown in fig. 5, since the filtering structure 100b is disposed in the vertical storage tank 71b and the separated water flows into the upper space 73b of the vertical storage tank 71b, the first water inlet pipe 41b of the backwash pump 4b can be directly connected to the upper space 73b of the vertical storage tank 71b, in addition to a backwash water source (not shown) or the first space 13b (not shown) of the membrane filtering assembly 1b, thereby saving the cost of separately providing a backwash water source.
Fig. 7 to 8 show a fourth embodiment of the present invention, in which an embodiment in which the filtering structure 100c, the membrane filtering unit 1c, the backwashing support pipe 2c, the first water spraying structure 3c, and the backwashing pump 4c are applied to the horizontal filtering apparatus 400c is illustrated. As shown in fig. 7 to 8, the horizontal filter device 400c includes the filter structure 100c described above, and further includes: a horizontal type storage tank 81c, in which a partition plate 82c is provided inside the horizontal type storage tank 81c to form a left space 83c and a right space 84 c; the isolation plate 82c has a second opening 821 c; the membrane filtration module 1c is arranged at the left side of the partition plate 82c, and the first opening 15c of the membrane filtration module 1c is communicated with the second opening 821c of the partition plate 82 c; and a raw water supply structure 86c communicating with the left space 83c of the horizontal storage tank 81 c; and a drainage structure 87c communicating with the right space 84c of the horizontal storage tank 81 c; by the structure, the purposes of filtering and backwashing simultaneously and continuously can be achieved.
The raw water supply structure 86c can inject raw water into the left space 83c of the horizontal storage tank 81 c. Depending on the usage, the raw water supply structure 86c may be provided with a pressure pump or may be configured to use a level difference (not shown) to inject the pressurized raw water into the left space 83c of the horizontal storage tank 81c, thereby increasing the efficiency of raw water filtration, generating power to flow the separation liquid to the right space 84c of the horizontal storage tank 81c, and facilitating the discharge of the separation liquid from the drainage structure 87 c; in this case, the sludge is gradually accumulated in the left space 83c of the horizontal storage tank 81c and gradually settled downward. A sewage collecting pipe 88c and a sewage draining pipe 89c are disposed at the bottom of the horizontal storage tank 81c for conveniently draining the sludge. The wall of the sewage collecting pipe 88c is provided with a plurality of openings, so that the sludge can be collected and discharged through the sewage discharging pipe 89 c.
As shown in fig. 7, the backwash support pipe 2c is disposed approximately horizontally in the horizontal storage tank 81 c. In addition, since the filtering structure 100c is disposed in the horizontal storage tank 81c and the separated water flows into the right space 84c of the horizontal storage tank 81c, the first water inlet pipe 41c of the backwash pump 4c can be directly connected to the right space 84c of the horizontal storage tank 81c, in addition to a backwash water source (not shown) or the first space 13c (not shown) of the membrane filtering assembly 1c, thereby saving the cost of separately providing a backwash water source.
FIG. 9 is a variation of the first sprinkler tube. The water spraying direction of the first water spraying opening 321d of the first water spraying pipe 32d may also be slightly deviated from the diameter direction of the membrane filtering assembly 1d, so as to simultaneously achieve the effects of backwashing the membrane filtering assembly and rotating the backwashing support pipe 2 d.
The above-mentioned embodiments are provided for illustrative purposes only, and should not be construed as limiting the present application, i.e., all modifications and variations that fall within the scope of the appended claims are intended to be embraced therein.
