Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a complete set of membrane concentration equipment. Background Technology

[0002] A membrane concentration system is a combination of equipment that uses membrane separation technology to concentrate liquids. Based on the selective permeability of membranes, under pressure, solvents (usually water) and small molecules permeate through the membrane, while large solute molecules (such as proteins, polysaccharides, and salts) are retained, thus concentrating the solution. Different types of membranes have different retention effects on molecules of different sizes and properties. Common membrane separation technologies include reverse osmosis, nanofiltration, ultrafiltration, and microfiltration. The appropriate membrane separation technology and corresponding membrane modules are selected based on the specific concentration requirements.

[0003] In existing technologies, such as patent CN210419508U, a membrane concentration system is proposed. A security filter is installed below the high-pressure membrane module, and the high-pressure pump and circulation pump are simultaneously mounted on a base. A low-pressure hose is installed at the inlet of the high-pressure pump, a high-pressure hose at the outlet, and a shock absorber is installed below the high-pressure pump base. The high-pressure membrane module consists of multiple membrane housings connected in parallel, with each group of multiple membrane housings forming a single unit. An exhaust cap is installed at the highest point of the low-pressure inlet pipe of the energy recovery unit. Key components such as valves are installed on the side of the frame. A shut-off valve is installed between the concentrate pipe of the high-pressure membrane module and the inlet pipe of the circulation pump. Through optimized design of the membrane concentration system, problems such as low space utilization, high pump vibration and noise, low membrane element efficiency, fluctuating energy recovery unit efficiency, difficulty in valve operation, disassembly, and maintenance, and fluctuating system efficiency are effectively solved.

[0004] However, when some equipment malfunctions, such as membrane module leakage or internal pipe blockage, it is difficult to disassemble, making it difficult for maintenance personnel to directly enter the interior for inspection and repair. This increases the difficulty of troubleshooting and repair, prolongs equipment downtime, affects production efficiency, and makes it impossible to thoroughly clean the inner wall of the tank and the surface of the membrane elements. This can easily lead to the accumulation of dirt and impurities, accelerate membrane contamination and damage, and shorten the membrane's service life. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a complete membrane concentration system that can easily separate microfiltration membrane tanks and ultrafiltration membrane tanks, allowing for the inspection, maintenance, or replacement of individual membrane modules without large-scale disassembly of the entire system. This significantly improves maintenance efficiency and reduces equipment downtime. During the membrane concentration process, the liquid to be treated needs to be continuously fed to components such as the microfiltration membrane tank and ultrafiltration membrane tank for filtration and concentration. The centrifugal pump ensures that the liquid passes through the membrane modules at a stable flow rate, guaranteeing the smooth progress of the membrane separation process.

[0006] To achieve the above objectives, a complete membrane concentration device is provided, including a support frame. A first limiting block is fixedly connected to the outside of the support frame. Multiple sliding blocks are slidably connected inside the first limiting block. A first connecting rod is rotatably connected to the outside of the sliding blocks. A first rotating rod is rotatably connected to one end of the first connecting rod. A locking block is rotatably connected to the outside of the first rotating rod. A fixing block is fixedly connected to the outside of the locking block. A second rotating rod is rotatably connected inside the fixing block. A second connecting rod is provided inside the locking block. A microfiltration membrane tank and an ultrafiltration membrane tank are fixedly connected to one end of the second connecting rod.

[0007] According to the membrane concentration equipment described above, a control box is fixedly connected inside the support, and a first motor is fixedly connected inside the support.

[0008] According to the membrane concentration equipment described above, the output end of the first motor is rotatably connected to a rotating shaft, the bottom of the rotating shaft is fixedly connected to a first connecting pipe, and a protective shell is fixedly connected to the outside of the first connecting pipe.

[0009] According to the membrane concentration equipment described above, a drive rod is rotatably connected inside the protective shell, a second motor is fixedly connected to the output end of the drive rod, and a first gear is fixedly connected to the outside of the drive rod.

[0010] According to the membrane concentration equipment described above, a second gear is meshed with the top of the first gear, a third rotating rod is fixedly connected inside the second gear, a fan blade is rotatably connected to one end of the third rotating rod, and a housing is rotatably connected to the outside of the fan blade.

[0011] According to the membrane concentration equipment described above, a base is fixedly connected to the bottom of the protective shell, and multiple suction cups are fixedly connected inside the base.

[0012] According to the membrane concentration equipment, a first pressure gauge is fixedly connected to the top of the first connecting pipe, a second connecting pipe is fixedly connected to the outside of the first connecting pipe, a support column is fixedly connected to one end of the second connecting pipe, and a discharge pipe is fixedly connected to the outside of the support column.

[0013] According to the membrane concentration equipment described above, a second pressure gauge is fixedly connected to the top of the first connecting pipe, a pipe is fixedly connected to the outside of the first connecting pipe, a fourth rotating rod is fixedly connected to the inside of the pipe, a piston is fixedly connected to the bottom of the fourth rotating rod, and a second limiting block is fixedly connected to the inside of the pipe.

[0014] Beneficial effects:

[0015] 1. By pulling the sliding block inside the first limiting block, the sliding block moves within the first limiting block, thereby driving the first connecting rod outside to move. Under the movement of the first connecting rod, the first rotating rod at one end rotates inside the locking block, causing the locking blocks to retract. Then, the microfiltration membrane tank and the ultrafiltration membrane tank are fixed. This allows maintenance personnel to easily separate the microfiltration membrane tank and the ultrafiltration membrane tank, and inspect, repair or replace the membrane module of the individual tank without having to disassemble the entire equipment on a large scale, thus greatly improving maintenance efficiency and shortening equipment downtime.

[0016] 2. Driven by a second motor and a drive rod, the external first gear rotates. The first gear drives the top second gear, which in turn drives the internal third rotating rod, causing the fan blades inside the outer casing to rotate. This provides sufficient pressure and flow rate for the liquid in the equipment, allowing it to circulate within the system. During membrane concentration, the liquid to be treated needs to be continuously fed into components such as microfiltration membrane tanks and ultrafiltration membrane tanks for filtration and concentration. The centrifugal pump ensures that the liquid passes through the membrane modules at a stable flow rate, guaranteeing the smooth operation of the membrane separation process.

A microfiltration membrane tank 8 is fixedly connected to one end of the second connecting rod 21. An ultrafiltration membrane tank 9 is fixedly connected to one end of the second connecting rod 21.

[0027] Specifically: by pulling the sliding block 16 inside the first limiting block 15, the sliding block 16 moves within the first limiting block 15, thereby driving the first connecting rod 17 outside to move. Under the movement of the first connecting rod 17, the first rotating rod 18 at one end rotates inside the locking block 19, causing the locking blocks 19 to retract, and then fixing the microfiltration membrane tank 8 and the ultrafiltration membrane tank 9.

[0028] The control box 2 is fixedly connected inside the bracket 1, and the first motor 3 is fixedly connected inside the bracket 1.

[0029] The output end of the first motor 3 is rotatably connected to a rotating shaft 4, the bottom of the rotating shaft 4 is fixedly connected to a first connecting pipe 5, and a protective shell 6 is fixedly connected to the outside of the first connecting pipe 5.

[0030] The protective shell 6 is rotatably connected to a drive rod 24, the output end of the drive rod 24 is fixedly connected to a second motor 23, and the drive rod 24 is fixedly connected to a first gear 25.

[0031] Specifically: Driven by the second motor 23, the drive rod 24 drives the external first gear 25 to rotate.

[0032] The top of the first gear 25 is meshed with the second gear 26. The inside of the second gear 26 is fixedly connected to the third rotating rod 27. One end of the third rotating rod 27 is rotatably connected to the fan blade 28. The outside of the fan blade 28 is rotatably connected to the outer casing 29.

[0033] Specifically: the first gear 25 drives the second gear 26 at the top to rotate, and the second gear 26 drives the third rotating rod 27 inside to rotate, which in turn rotates the fan blade 28 inside the outer casing 29 at one end.

[0034] The bottom of the protective shell 6 is fixedly connected to a base 30, and multiple suction cups 31 are fixedly connected inside the base 30.

[0035] The top of the first connecting pipe 5 is fixedly connected to a first pressure gauge 7, the outside of the first connecting pipe 5 is fixedly connected to a second connecting pipe 10, one end of the second connecting pipe 10 is fixedly connected to a support column 13, and the outside of the support column 13 is fixedly connected to a discharge pipe 14.

[0036] The top of the first connecting pipe 5 is fixedly connected to a second pressure gauge 11, the outside of the first connecting pipe 5 is fixedly connected to a pipe 12, the inside of the pipe 12 is fixedly connected to a fourth rotating rod 32, the bottom of the fourth rotating rod 32 is fixedly connected to a piston 33, and the inside of the pipe 12 is fixedly connected to a second limiting block 34.

[0037] Specifically: by rotating the fourth rotating rod 32, the bottom piston 33 is disengaged from the groove inside the second limiting block 34.

[0038] Working Principle: The microfiltration membrane tank 8 and the ultrafiltration membrane tank 9 are placed in front of the locking block 19. Pulling the sliding block 16 inside the first limiting block 15 causes the sliding block 16 to move within the first limiting block 15, thereby driving the external first connecting rod 17 to move. The movement of the first connecting rod 17 causes one end of the first rotating rod 18 to rotate inside the locking block 19, causing the locking blocks 19 to retract. This then fixes the microfiltration membrane tank 8 and the ultrafiltration membrane tank 9 in place. This allows maintenance personnel to easily separate the microfiltration membrane tank 8 and the ultrafiltration membrane tank 9 for inspection, repair, or replacement of individual tanks and membrane modules without large-scale disassembly of the entire equipment, greatly improving maintenance efficiency and shortening equipment downtime. The feed solution then enters the microfiltration membrane tank 8 and the ultrafiltration membrane tank 9 for pretreatment to remove large particulate impurities, suspended solids, colloids, etc. To prevent these substances from clogging the membrane modules and affecting the membrane's performance and lifespan, under pressure or concentration gradient, the solvent permeates through the semi-permeable membrane, forming the permeate that is discharged from the system; while the solute and some large molecules are retained on the feed side of the membrane. As the solvent is continuously separated out, the solute concentration in the solution gradually increases, achieving a concentration effect. Finally, according to actual needs, the concentrated solution and permeate are further processed. At the bottom of the microfiltration membrane tank 8 and ultrafiltration membrane tank 9, driven by the second motor 23 and the drive rod 24, the external first gear 25 rotates. The first gear 25 drives the top second gear 26 to rotate, which in turn drives the internal third rotating rod 27 to rotate, rotating the fan blade 28 inside the outer casing 29 at one end. This provides sufficient pressure and flow rate for the liquid in the equipment, allowing it to circulate in the system. During the membrane concentration process, the liquid to be treated needs to be continuously transported to the microfiltration membrane tank 8, ultrafiltration membrane tank 9, and other components for filtration and concentration. The centrifugal pump ensures that the liquid passes through the membrane modules at a stable flow rate, guaranteeing the smooth progress of the membrane separation process.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
