When immersed in the liquid to be filtered, the liquid to be filtered is located on the water inlet side of the filter membrane 12, and one end of the membrane-side pipe 13 is communicated with the water outlet-side space formed by the bracket 11 and the filter membrane 12. The pumping line assembly 20 includes a pump-side pipe 21 and a pump 22, and one end of the pump-side pipe 21 is connected to the pump 22. The other end of the membrane-side pipe 13 and the other end of the pump-side pipe 21 are detachably connected by a connecting structure. When liquid is filtered, the pump-side pipeline 21 and the membrane-side pipeline 13 are connected together, liquid to be filtered enters the water outlet-side space of the filtering membrane 12 after being filtered by the filtering membrane 12 from the water inlet side of the filtering membrane 12 through the driving action of the pump 22, and is pumped out through the membrane-side pipeline 13 and the pump-side pipeline 21 in sequence, when the filtering membrane module 10 needs to be taken out for cleaning, the pump-side pipeline 21 and the membrane-side pipeline 13 are disassembled, the filtering membrane module 10 can be lifted to the position above the liquid level through the lifting chain 30, and the filtering membrane module 10 is moved out so as to be thoroughly cleaned.

In general, in order to facilitate the assembly and disassembly of the pump-side pipe 21 and the membrane-side pipe 13, referring to fig. 1, the connection position of the pump-side pipe 21 and the membrane-side pipe 13 is located above the liquid level, and if the filtration membrane module 10 can be lifted from the liquid level, a higher lifting space is required to ensure that the membrane-side pipe 13 does not interfere with the top of the space, which increases the height of the lifting frame, increases the engineering cost, and limits the use of the submerged filtration system in a low space, and in this regard, as shown in fig. 1, in the present application, the connection structure employs a self-coupling sealer 50, and the self-coupling sealer 50 includes a first portion 51 connected to the membrane-side pipe 13 and a second portion 52 connected to the pump-side pipe 21, and the first portion 51 is located below the top surface of the filtration membrane module 10, preferably located near the bottom of the filtration membrane module 10, the first portion 51 includes a first sealing surface, and the second portion 52 includes a second sealing surface, the first sealing surface being capable of engaging and disengaging with the second sealing surface by lifting and lowering, and the membrane-side pipe 13 communicates with the pump-side pipe 21 when the first sealing surface and the second sealing surface are engaged. Through setting up self coupling sealer 50, need not the manual work and carry out the dismouting to connecting line, the self sealss of first part 51 and second part 52 can be realized to the guide effect that utilizes spacing guide structure 40, so, can be less than the top surface setting of filtration membrane module 10 with first part 51, for example, the setting is in the position that is close to filtration membrane module 10 bottom as shown in FIG. 1, so, refer to FIG. 2, play the gallows only need be higher than the support 11 the highest position can, reduced by a wide margin and lifted required space height, application scope is wider.
For the convenience of arrangement, the membrane-side pipe 13 and the first guide portion are located on the same side of the filtering membrane module 10 in the radial direction of the filtering membrane, so that, referring to fig. 1, the pump-side pipe 21 and the second guide portion can be both disposed on one side of the space for containing the liquid to be filtered, which is more convenient for arrangement of each structure.
Because membrane side pipeline 13 and first guide part all set up the homonymy at filtration membrane module 10, and the chain of lifting by crane all is the geometric center of connecting at support 11 top usually, cause very easily like this to lift by crane the in-process and take place crooked, to this problem, preferably, filtration membrane module 10 in this application still includes second counter weight structure 70, the axis that filtration membrane can be guaranteed to second counter weight structure 70 sets up keeps vertical extension all the time, thereby avoid all setting up the problem that takes place crooked at filtration membrane module 10's homonymy because of membrane side pipeline 13 and first guide part, further guarantee to lift by crane the stable and reliable nature of reset process.
The second weight structure 70 may be a structure attached to the bracket 11, for example, in the embodiment shown in fig. 1, the bracket 11 includes a longitudinal beam 111 and a cross beam 112, the second weight structure 70 includes a weight strip 71, the weight strip 71 is aligned with the extending direction of the longitudinal beam 111 and is attached to the outer side surface of the longitudinal beam 111, so that the overall shape of the bracket 11 is not affected, a good weight effect can be achieved, and the arrangement of the second weight structure 70 is facilitated, for example, the weight strip 71 is formed by turning one of the longitudinal beams 111 outward, or the weight strip 71 is fixed to the longitudinal beam 111 through a fastener.
In another preferred embodiment, the support 11 itself is weighted by the material or structure thereof, so that the support 11 itself constitutes the second weighting structure 70, for example, a plurality of weight ports may be provided on the structure of the support 11 on the side thereof adjacent to the membrane-side duct 13 and the first guide portion, and further for example, the support 11 includes a first material portion and a second material portion, the first material portion being located on the side thereof adjacent to the membrane-side duct 13 and the second material portion being located on the side thereof facing away from the membrane-side duct 13 in the radial direction of the filtration membrane, the material density of the first material portion being lower than that of the second material portion, so that the shape structure of the support 11 does not need to be changed, thereby ensuring the shape integrity of the support 11.
Of course, it will be understood that the balance of the lifting process can also be ensured by changing the connection position of the lifting chain to the filtration membrane module 10, i.e. the connection position of the lifting chain is arranged above the overall center of gravity of the filtration membrane module 10.
The limiting and guiding structure 40 may be any structure that can achieve a guiding function through cooperation, for example, a matching structure of a sliding block and a sliding chute, in a preferred embodiment, as shown in fig. 1, the first guiding portion includes a sliding part 42, a guiding hole 421 is formed in the sliding part 42, the second guiding portion includes a vertical guiding rail 41, the vertical guiding rail 41 is fixedly disposed in a space for containing liquid to be filtered and extends vertically, the sliding part 42 is connected to the bracket 11, the sliding part 42 can be sleeved on the vertical guiding rail 41 and slide along the vertical guiding rail 41, so that the filtering membrane assembly 10 can be lifted along with the sliding part 42 along the vertical guiding rail 41, and the sliding part 42 can be separated from the vertical guiding rail 41 by the top of the vertical guiding rail 41. Therefore, the hole wall of the guide hole 421 is matched with the vertical guide rail 41, so that the stability and reliability of the lifting reset process are ensured.
In the embodiment shown in fig. 1, since the bottom of the filtering membrane module 10 is suspended, in the state shown in fig. 1, the filtering membrane module 10 has a risk of rolling (for example, the left side in fig. 1), and for this problem, preferably, the sliding member 42 is provided with a first counterweight structure on the side of the vertical guide rail 41 away from the filtering membrane module 10 (i.e., the right side in fig. 1), and by providing the first counterweight structure, the stress condition of the whole filtering system can be improved, so that the rolling of the filtering membrane module 10 is effectively avoided. The first counterweight structure may be any structure capable of performing counterweight, for example, a counterweight fixedly connected to the sliding member 42, and for example, the weight of the sliding member 42 on the side of the vertical guide rail 41 away from the filtering membrane module 10 may be increased, so that the sliding member 42 itself constitutes the first counterweight structure.
Because some shaking inevitably occurs in the process that the lifting chain 30 drives the filtering membrane assembly 10 to horizontally move, if the hole wall of the guide hole 421 needs to be well matched with the vertical guide rail 41, the shape of the guide hole 421 and the vertical guide rail 41 needs to be adapted, so that the alignment of the guide hole 421 and the vertical guide rail 41 is difficult, in order to facilitate the alignment of the guide hole 421 and the vertical guide rail 41, preferably, as shown in fig. 5, in the vertical direction, the guide hole 421 includes a first large-diameter section 4211 and a small-diameter section 4212, the small-diameter section 4212 is located above the first large-diameter section 4211, the small-diameter section 4212 is adapted to the cross section of the vertical guide rail 41, and the cross section area of the first large-diameter section 4211 is larger than the cross section area of the vertical guide rail 41. Because the cross-sectional area of the first large-diameter section 4211 is larger than the cross-sectional area of the vertical guide rail 41, even if the filter membrane assembly 10 slightly shakes in the horizontal direction, the vertical guide rail 41 can conveniently penetrate into the first large-diameter section 4211, and then the first large-diameter section 4211 slides into the small-diameter section 4212 and is matched with the inner wall of the small-diameter section 4212, so that guiding is realized.
It is further preferable that the top surface of the vertical guide rail 41 is provided as a spherical surface so that the vertical guide rail 41 is more smoothly slid into the guide hole 421.
Further preferably, the guiding hole 421 further includes a second large diameter section 4213, the second large diameter section 4213 is located above the small diameter section 4212, the cross-sectional area of the second large diameter section 4213 is larger than the cross-sectional area of the vertical guide rail 41, and the first large diameter section 4211 and the small diameter section 4212, and the second large diameter section 4213 and the small diameter section 4212 are connected by smooth curved surface transition. The second large-diameter section 4213 can effectively prevent the sliding part 42 from being stuck in the sliding process, and even if the sliding part 42 is shifted horizontally due to horizontal component force in the up-and-down movement process, a space is provided for the vertical guide rail 41 due to the existence of the second large-diameter section 4213, so that the phenomenon of being stuck is effectively avoided.
In order to achieve the guiding function of the sliding of the vertical guide rail 41 into the guide hole 421, it is further preferable that the cross-sectional area of the first large-diameter section 4211 is gradually reduced from bottom to top as shown in fig. 5.
