Description

Technical Field

[0001] The utility model relates to the technical field of ultrafiltration membranes, and specifically relates to an ultrafiltration membrane module that is convenient for installation. Background Art

[0002] An ultrafiltration membrane is a membrane filtration technology in separation technology, which can physically separate macromolecular substances (such as proteins, colloids, etc.) from small molecular substances (such as water, ions, etc.) in a solution. Ultrafiltration membranes are widely used in fields such as drinking water, wastewater treatment, biotechnology, and the food industry. However, in the prior art, ultrafiltration membrane modules have problems such as difficult installation and disassembly, and high costs.

[0003] The utility model patent with the publication number CN213942698U discloses an ultrafiltration membrane rack that is convenient for the tie bars of a water tank. In this ultrafiltration membrane rack, membrane curtain mounting holes are used to install ultrafiltration membrane curtains; the equidistantly arranged membrane curtain mounting holes are not completely continuously distributed on the transverse columns; two skipped hole positions are provided on the transverse columns to reserve a passage for the tie bars; the tie bar reserved passage is used to give space for the longitudinal tie bars to pass through. When the ultrafiltration membrane curtain is installed on the ultrafiltration membrane rack, it is installed in a side-by-side manner in two rows; therefore, in the middle of a pair of transverse columns of the ultrafiltration membrane rack where there are membrane curtain mounting holes, there is also a middle cross beam parallel to this pair of transverse columns; on the left and right sides corresponding to the middle cross beam, there are also equidistantly arranged membrane curtain mounting holes that are not completely continuous. Above and below the ultrafiltration membrane rack, there is a middle cross beam each to correspondingly install two rows of ultrafiltration membrane curtains. At the same time, a water outlet pipeline is provided between the upper and lower parallel middle cross beams; the water outlet pipeline is parallel to the longitudinal columns to provide longitudinal support for the ultrafiltration membrane rack. The position where the middle cross beam is located is the reserved space for the water tank transverse tie bars to pass through. Below the transverse column at the lower part, there is also a pair of parallel bottom transverse columns; there are multiple parallel exhaust pipelines between the bottom transverse columns; the bottom transverse columns and the exhaust pipelines further strengthen the structural strength of the ultrafiltration membrane rack. Above the ultrafiltration membrane rack, there is also an additional cross beam; an air inlet is provided on this cross beam, and a water outlet is provided on the middle cross beam. During actual operation, the water filtered by the ultrafiltration membrane curtain is concentrated by the water outlet pipeline and discharged through the water outlet; the other end is connected to the outside pipeline through the air inlet to transport the gas required for the operation of the ultrafiltration membrane curtain, and is discharged through the exhaust pipeline.

[0004] This solution improves the existing ultrafiltration membrane rack, enabling the tie bars of the water tank to pass through the membrane rack and the inner surface of the corresponding side of the water tank, thereby preventing the ultrafiltration membrane rack from deforming due to the tension of the tie bars and affecting the normal operation and service life of the ultrafiltration membrane rack. However, there are still problems such as difficult installation and disassembly, and high costs. Content of the Utility Model

[0026] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments:

[0027] The present utility model mainly consists of three structures: a membrane rack, a water collection system, and a gas collection system.

[0028] 1. Membrane rack

[0029] It includes a membrane rack base and membrane rack splicing parts. As shown in the attached Figure 2 figure, the outer frame of the membrane rack base is composed of two mutually perpendicular or parallel columns, namely the long horizontal column 12 and the short horizontal column 13. Specifically, it includes two long horizontal columns 12 and two short horizontal columns 13 located above, as well as four longitudinal columns 11 connecting the corresponding lower parts; on a pair of relatively parallel short horizontal columns 13, several membrane curtain fixing parts 16 are arranged at equal intervals, and the membrane curtain fixing parts 16 are used to install the ultrafiltration membrane curtain 1; below the short horizontal column 13, a pair of relatively parallel short horizontal angle steels 14 are connected inside the two longitudinal columns 11, and several threaded holes are arranged at equal intervals on the short horizontal angle steels 14 for connecting the U-shaped pipe clamps 15 to facilitate the fixation of the aeration branch pipes 27; and at the positions corresponding to the longitudinal columns 11 on the long horizontal column 12 and the short horizontal column 13, four longitudinal inner pipes of the sleeve 17 are connected for splicing the upper splicing parts of the membrane rack. As shown in the attached Figure 3 figure, in the membrane rack splicing parts, four outer pipes of the sleeve 18 are connected to the inner pipes of the sleeve 17 of the membrane rack base, and the fixing part 19 is connected above the inner side of the outer pipe of the sleeve 18. The fixing part 19 and the angle steel limiting part 20 are bolt-connected through threaded holes, and several threaded holes are arranged at equal intervals on the angle steel limiting part for fixing the membrane curtain 1. Thus, the membrane rack base and the membrane rack splicing parts jointly form the membrane rack.

[0030] 2. Water collection system

[0031] It includes a water collection pipe and other pipe fittings. Several round holes are arranged at equal intervals on the water collection pipe 2 for connecting the saddle joints 23. Both ends of the water collection pipe 2 are respectively connected with a plug 21 and a loose flange 22 to facilitate subsequent connection to the water production pipeline; the saddle joints 23 are sequentially connected with a union 24, an elbow 25, and an external thread joint 26 through pipes, and the external thread joint 26 is connected to the water outlet of the membrane curtain 1. Thus, the water filtered by the ultrafiltration membrane curtain 1 is concentrated through the water collection pipe 2 and discharged through the loose flange 22 to connect to the water production pipeline.

[0032] 3. Gas collection system

[0033] It includes a header pipe, aeration branch pipes and other pipe fittings. There are several round holes arranged at equal intervals on the header pipe 3 for connecting the second saddle joint 23-2. The two ends of the header pipe 3 are respectively connected to the second plug 21-2 and the second loose flange 22-2 to facilitate subsequent connection of the aeration pipeline. The second saddle joint 23-2 is successively connected to the second union 24-2, the second elbow 25-2, the aeration branch pipe 27 and the aeration branch pipe plug 28 by pipes. Thus, the gas required for the operation of the ultrafiltration membrane curtain 1 is conveyed through the connection between the second loose flange 22-2 and the external aeration pipeline and discharged through several air holes arranged at equal intervals on the aeration branch pipe 27.

[0034] The working process of the utility model is as follows: During actual operation, first fix the four longitudinal columns 11 in the membrane rack bottom frame to the bottom of the pool. Then connect the four outer sleeves 18 in the membrane rack splicing parts to the inner sleeves 17 of the membrane rack base. Then fix the membrane curtain 1 with the membrane curtain fixing part 16, and connect the membrane curtain 1 and the angle steel limiting part 20 with bolts through threaded holes. Finally, connect the fixing part 19 and the angle steel limiting part 20 with bolts, thus completing the fixation of the membrane curtain 1 and the membrane rack. The water outlet above the membrane curtain 1 is connected to the water collection system. The water filtered by the ultrafiltration membrane curtain 1 is concentrated through the header pipe 2 and discharged through the loose flange 22 of the water collection system to connect to the water production pipeline. The gas collection system is configured below the membrane curtain 1. The aeration branch pipe 27 is fixed by the short transverse angle steel 14 and the U-shaped pipe clamp 15 of the membrane rack bottom frame. The gas required for the operation of the ultrafiltration membrane curtain 1 is conveyed through the connection between the second loose flange 22-2 of the gas collection system and the external aeration pipeline, and finally discharged through several air holes arranged at equal intervals on the aeration branch pipe 27. The utility model adopts a spliced membrane rack and combined pipe fittings, which is more convenient for the installation and disassembly operations of the ultrafiltration membrane module during actual work.

[0035] In addition, in the water collection system of the utility model, a metal hose can be used to replace the plastic hard pipe to connect the header pipe and the membrane curtain, so that the membrane curtain can move up and down within a small range to prevent the breakage of the header pipe caused by the deformation of the lower bottom plate where the membrane rack is fixed. The main body of the membrane rack of the utility model adopts a splicing method, which greatly reduces the overall weight and volume and solves the problem of inconvenient installation and disassembly. At the same time, the utility model can reduce the material used for the membrane rack and utilize the gas collection and water collection functions of UPVC pipe fittings instead of steel pipes, so as to achieve the purpose of cost saving.

[0036] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. The standard parts used can be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding in the prior art.
