[0027] In detail, the diameter of the transmission spur gear 8 is smaller than the diameter of the reduction spur gear 9;

[0028] Embodiment 2:

[0029] See also Figure 2-5 , this embodiment provides a technical solution based on the first embodiment: the placement component 4 includes a displacement frame 10, a placement plate 11, an assembly seat 12, a positioning frame 13, a support frame 14 and a hydraulic cylinder 15, one end of the carrying frame 3 is slidably connected to the displacement frame 10, one side of the bottom of the displacement frame 10 is fixedly connected to the placement plate 11, both sides of the placement plate 11 are fixedly connected to the assembly seat 12, and the positioning frame 13 is rotatably connected between the two assembly seats 12, the top of the displacement frame 10 is fixedly connected to the support frame 14, the top of the support frame 14 is rotatably connected to the hydraulic cylinder 15, and the output end of the hydraulic cylinder 15 is rotatably connected to the positioning frame 13, and the middle of the carrying frame 3 is fixedly connected to the transmission seat 16;

[0030] It can be understood that the hydraulic cylinder 15 is started to push the positioning frame 13 to rotate under the support of the assembly seat 12 until the positioning frame 13 contacts the nanofiltration membrane, thereby positioning the nanofiltration membrane between the placement plate 11 and the positioning frame 13;

[0031] In detail, a limiting slot is provided at one end of the mounting frame 3, and the displacement frame 10 is connected inside the limiting slot. By setting the limiting slot, the displacement direction of the displacement frame 10 can be stably guided to avoid uncontrollable displacement of the displacement frame 10;

[0032] Furthermore, the ends of the two assembly seats 12 close to each other are each provided with a support hole, and the end of the positioning frame 13 close to the assembly seat 12 is fixedly connected with a rotating shaft, and the rotating shaft is connected to the inside of the support hole through a ball bearing. The setting of the rotating shaft can improve the smoothness of the connection between the positioning frame 13 and the assembly seat 12;

[0033] The placement component 4 also includes a linkage shaft 17, a transmission plate 18, a drive motor 19, an eccentric drive plate 20, a linkage spur gear 21 and a linkage rack 22. The bottom end of one side of the transmission seat 16 is rotatably connected to the linkage shaft 17, one end of the linkage shaft 17 is fixedly connected to the transmission plate 18, the top of the transmission seat 16 is fixedly connected to the drive motor 19, the output end of the drive motor 19 is fixedly connected to the eccentric drive plate 20, and one end of the eccentric drive plate 20 is also slidably connected to the inside of the transmission plate 18, the outer side of the linkage shaft 17 is fixedly connected to the linkage spur gear 21, and the top of the displacement frame 10 near one end of the linkage spur gear 21 is fixedly connected to the linkage rack 22, and the linkage rack 22 is meshed with the linkage spur gear 21.

[0034] In summary, the driving motor 19 is started to drive the eccentric driving plate 20 to rotate, and the connection between the eccentric driving plate 20 and the transmission plate 18 is coordinated, so that the eccentric driving plate 20 continuously pushes the transmission plate 18, and because the transmission plate 18 is supported by the linkage shaft 17, it can drive the linkage shaft 17 to rotate, so that the linkage spur gear 21 reciprocates to shift the linkage rack 22, thereby driving the displacement frame 10 to slide back and forth at the mounting frame 3;

[0035] Furthermore, a guide shaft is fixedly connected to one end of the eccentric drive plate 20 away from the drive motor 19, a linkage groove is opened in the middle of the transmission plate 18, and the eccentric drive plate 20 is connected to the inside of the linkage groove through the guide shaft. By utilizing the structural coordination of the guide shaft and the linkage groove, during the continuous rotation of the eccentric drive plate 20, the guide shaft will be driven to slide adaptively inside the linkage groove, and since the eccentric drive plate 20 rotates in a circle, when the eccentric drive plate 20 rotates one circle, the transmission plate 18 returns to the origin.

[0036] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0037] When working, firstly place the nanofiltration membrane on the side of the placement plate 11 close to the positioning frame 13, then start the hydraulic cylinder 15 to push the positioning frame 13 to rotate under the support of the assembly seat 12 until the positioning frame 13 contacts the nanofiltration membrane, so as to position the nanofiltration membrane between the placement plate 11 and the positioning frame 13;

[0038] Restart the transmission motor 7 to drive the transmission shaft 6 to rotate, prompting the transmission spur gear 8 to shift the reduction spur gear 9, thereby driving the support shaft 2 to rotate, and immersing the placement plate 11 into the immersion box 1, and at the same time start the drive motor 19 to drive the eccentric drive plate 20 to rotate, and cooperate with the connection between the eccentric drive plate 20 and the transmission plate 18, so that the eccentric drive plate 20 continues to push the transmission plate 18, and because the transmission plate 18 is supported by the linkage shaft 17, it can drive the linkage shaft 17 to rotate, prompting the linkage spur gear 21 to reciprocate and shift the linkage rack 22, thereby driving the displacement frame 10 to slide back and forth at the mounting frame 3, and shaking the nanofiltration membrane at the placement plate 11, thereby forming an immersion cleaning of the nanofiltration membrane.
