In operation, when the filtration is completed and the gap between the high-precision membrane modules 71 is filled with fresh water, the water valve 12 is opened and the fresh water flows out to the water storage tank for storage.

Specifically, every two high-precision membrane assemblies 71 are provided with a top plate 14 above the interval, and a plurality of the top plates 14 are provided with holes for connecting shunt pipelines.

Specifically, each high-precision membrane assembly 71 comprises a guide plate 711, a membrane frame 712, a high-precision membrane 713, a supporting plate 714 and a baffle 715, the membrane frame 712 is arranged on one side of the guide plate 711, the high-precision membrane 713 is arranged on the other side of the membrane frame 712, the supporting plate 714 is arranged on one side of the high-precision membrane 713, the baffle 715 is arranged on one side of the supporting plate 714, a retention cavity with a certain space is formed between each supporting plate 714 and the high-precision membrane 713, an opening is formed in each baffle 715, and a pipeline connected with a one-way valve 716 is arranged on each opening.

The working principle is as follows: inputting raw water to be treated into a raw liquid tank 4, conveying the raw water in the raw liquid tank 4 to a pretreatment cartridge filter 1 through a feed pump 2 for primary filtration, wherein the treated raw water needs to meet the requirement that suspended matters are less than 100mg/L, oil matters are less than 50mg/L, the operation effect of free residual chlorine is the best below 1mg/L, after filtration is completed, filtration treatment is carried out through a primary filter 5, the treated raw water enters a primary filter water tank 6 for storage after passing treatment, a first electromagnetic valve 72 is opened while the pretreated liquid in the primary filter water tank 6 is pumped out through a high-pressure water pump 3, at the moment, the liquid flows into a gap between a first high-precision membrane module 71 and an end plate 73 from a pipeline, at the moment, the high-pressure water pump 3 continuously conveys the liquid into the gap between the end plate 73 and the first high-precision membrane module 71, and a large amount of solutes pass through the first high-precision membrane module 71 due to pressure, then filtered to a gap between the first high-precision membrane assembly 71 and the second high-precision membrane assembly 71 through a check valve 716, the setting of the check valve 716 can prevent the filtered liquid from flowing back to the gap between the end plate 73 and the first high-precision membrane assembly 71, when water molecules in the gap between the end plate 73 and the first high-precision membrane assembly 71 reach a certain amount, the first electromagnetic valve 72 is controlled to be closed, the first partial electromagnetic valve 76 is opened, raw water enters the gap between the first high-precision membrane assembly 71 and the second high-precision membrane assembly 71 from a shunt pipe to be filtered, the working steps are repeated until the filtered raw water is discharged and collected from a water outlet, and the water valve 12 on the water outlet pipe 11 communicated with the gap between the end plate 73 and the first high-precision membrane assembly 71 is opened while the first partial electromagnetic valve 76 is opened, so that the water molecules between the end plate 73 and the first high-precision membrane assembly 71 are discharged to the fresh water tank 10, when the device needs to be disassembled, replaced or cleaned, the output end of the hydraulic cylinder 81 drives the U-shaped plate 82 to push towards the direction of the high-precision membrane group device 7, two sliding blocks 83 arranged on the U-shaped plate 82 slide in sliding grooves arranged on two fixed clamping blocks 84 below the U-shaped plate 82 during movement, so that the two fixed clamping blocks 84 are tightened inwards, as the L-shaped supporting plates 85 arranged below the two fixed blocks respectively abut against the two fixed clamping blocks 84, the two fixed clamping blocks 84 can only translate along the edge of the high-precision membrane group device 7, when the hydraulic cylinder 81 drives the U-shaped plate 82 to move, the driving strip 94 arranged below the U-shaped plate 82 also moves simultaneously and drives the strip 94 to drive a fixed shaft fixed with the fixed strip 94 to move, when the fixed shaft moves, one end of the diamond-shaped telescopic piece 92 drives a plurality of telescopic connecting rods connected with the fixed shaft to move, and a plurality of telescopic connecting rods move to drive the high-precision membrane assembly 71 to be opened, because the distance between the diamond-shaped telescopic parts 92 is increased when the diamond-shaped telescopic parts 92 are driven by the hydraulic cylinder 81 to move towards the direction of the high-precision membrane assembly 7, and the high-precision membrane assembly 71 is pushed back to reset, when cleaning or disassembly is needed, the two fixed clamping blocks 84 reset when the U-shaped plate 82 is pulled out by the contraction of the output end of the hydraulic cylinder 81, so that the clamping and fixing of the two end plates 73 on the high-precision membrane assembly 71 are released, and the slide rails 15 arranged below the high-precision membrane assembly 71 prevent the U-shaped plate 82 from being misaligned when being pulled out and retracted, the middle part of the U-shaped plate 82 is of a telescopic structure, the output end of the hydraulic cylinder 81 contracts and simultaneously drives the whole diamond-shaped telescopic part 92 to reset, and simultaneously the diamond-shaped telescopic part 92 drives a plurality of telescopic connecting rods to move, the telescopic connecting rods drive the high-precision membrane components 71 connected with the telescopic connecting rods to contract and clamp.
