Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water treatment membrane element protective liquid replacement device. Background Art

[0002] The existing Chinese patent document with announcement number CN208526330U discloses a water treatment membrane element protective liquid replacement device, which proposes that the utility model provides a water treatment membrane element protective liquid replacement device with reasonable structural design, low labor intensity, sufficient perfusion, and thorough draining. The inlet and outlet trolleys are movably installed on the ground; the material frame is used to load the water treatment membrane elements, and it cooperates with the inlet and outlet trolleys, the front lifting trolley, and the rear lifting trolley; the front lifting trolley and the rear lifting trolley are both installed in the replacement chamber; the front lifting trolley includes a front moving mechanism and a front lifting mechanism, the front moving mechanism is installed in a translational manner on the top of the replacement chamber, and the front lifting mechanism is installed in a lifting manner on the front moving mechanism; the rear lifting trolley includes a rear moving mechanism and a rear lifting mechanism, the rear moving mechanism is installed in a translational manner on the top of the replacement chamber, and the rear lifting mechanism is installed in a lifting manner on the rear moving mechanism; the liquid storage tank is installed in the replacement chamber.

[0003] However, the above scheme lacks a limiting mechanism for the material frame. When the front lifting mechanism of the front lifting trolley and the rear lifting mechanism of the rear lifting trolley are lifted to different heights, the material frame and the water treatment membrane elements are separated from the liquid storage tank and form a certain angle with the ground. In the process of draining the water treatment membrane elements and allowing the excess protective liquid in the material frame to flow back into the liquid storage tank, the stability of the water treatment membrane elements therein cannot be guaranteed when the angle of the material frame changes. When multiple water treatment membrane elements are placed in the material frame, the water treatment membrane elements in the material frame are very likely to fall off as the angle of the material frame changes. The falling off will cause damage to the water treatment membrane elements, thereby affecting their use effect. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-Figure 3The utility model provides a technical solution: a water treatment membrane element protective liquid replacement device; in order to improve the use effect of the material frame 1, a limit frame 2 is provided on the surface of the material frame 1, a limit groove 3 is provided on the surface of the limit frame 2, and a through groove 8, a through hole 12 and a through hole 2 13 are provided on the surface of the material frame 1, a guide rod 7 and a slider 14 and a limit shell 15 are provided on the surface of the limit plate 5, and a spring 6 is provided on the guide rod 7, a positioning block 16 is provided on the surface of the driving rod 9, and a plurality of through grooves 10 are provided on the outer surface of the material frame 1, and the limit plate 5 is provided inside the material frame 1 , there are two groups of limit frames 2, and the two groups of limit frames 2 are correspondingly arranged in the material frame 1. One group of limit frames 2 is fixed on an inner wall surface of the material frame 1, and the other group of limit frames 2 is fixed on the inner end surface of the limit plate 5. A plurality of water treatment membrane elements 4 are provided in the material frame 1, and the end of the water treatment membrane element 4 is provided in the limit groove 3. The outer end of the drive rod 9 passes through the through hole 2 13, the positioning block 16 corresponds to the through groove 8, the guide rod 7 corresponds to the through hole 12, and the outer end of the guide rod 7 passes through the through hole 12. The spring 6 is provided inside the material frame 1; when the water treatment membrane element 4 is moved toward the material frame 1, the internal space of the material frame 1 is increased by pulling the driving rod 9 to drive the limiting plate 5 to move outward. When the positioning block 16 passes through the through slot 8 and moves to the outside of the material frame 1, the driving rod 9 is rotated to change the orientation of the positioning block 16 so that the positioning block 16 abuts against the surface of the material frame 1 to limit the limiting plate 5. The elastic performance of the spring 6 ensures the stability of the limiting plate 5 when it is limited. Then, the water treatment membrane element 4 is placed in the feed frame 1 so that one end of the water treatment membrane element 4 is in the limiting slot 3 of the limiting frame 2 for one end limit, and then the driving rod 9 is rotated. The positioning block 16 is rotated to the through groove 8, and the driving rod 9 is slowly loosened so that the limiting plate 5 is driven to move inward by the elastic support of the spring 6, so that the other end of the water treatment membrane element 4 enters the limiting groove 3 of the other set of limiting frames 2 to limit it. The water treatment membrane element 4 is limited by the two sets of limiting frames 2, which effectively ensures its stability in the material frame 1 and prevents the water treatment membrane element 4 from falling from the material frame 1 when the angle of the material frame 1 changes. When the angle of the material frame 1 changes, the liquid inside the material frame 1 is discharged from the through groove 10, thereby improving the use effect of the material frame 1.

[0023] Example 2

[0024] On the basis of Example 1, in order to improve the stability of the limit plate 5, two groups of slide grooves 11 are symmetrically opened on both sides of the inner wall surface of the material frame 1, and the slide grooves 11 are trapezoidal. The limit plate 5 is arranged inside the material frame 1, and the slider 14 is trapezoidal. The slider 14 corresponds to and fits the slide groove 11, and the slider 14 is slidably connected in the slide groove 11; when the limit plate 5 is displaced, the slider 14 moves in the slide groove 11 to ensure its stability, thereby avoiding the limit plate 5 from tilting during displacement, thereby further improving the stability and reliability of the limit plate 5 when in use.

[0025] In actual use, the protective liquid replacement process of the water treatment membrane element 4 is the same as that of a water treatment membrane element protective liquid replacement device disclosed in the Chinese patent document with announcement number CN208526330U. When the water treatment membrane element 4 is installed in the material frame 1, the limit plate 5 is driven outward by pulling the drive rod 9 to increase the internal space of the material frame 1. When the positioning block 16 passes through the through groove 8 and moves to the outside of the material frame 1, the drive rod 9 is rotated to change the orientation of the positioning block 16 so that the positioning block 16 is pressed against the surface of the material frame 1 to limit the limit plate 5. The elastic performance of the spring 6 is used to ensure the stability of the limit plate 5 when it is limited. Then, the water treatment membrane element 4 is placed in the feed frame 1 so that one end of the water treatment membrane element 4 is in the limit groove 3 of the limit frame 2 for one end limit, and then the drive rod is rotated. The movable rod 9 rotates the positioning block 16 to the through groove 8, and slowly loosens the driving rod 9 so that the limit plate 5 is driven inward by the elastic support of the spring 6, so that the other end of the water treatment membrane element 4 enters the limit groove 3 of the other group of limit frames 2 to limit it. The water treatment membrane element 4 is limited by the two groups of limit frames 2, which effectively ensures its stability in the material frame 1 and prevents the water treatment membrane element 4 from falling from the material frame 1 when the angle of the material frame 1 changes. When the angle of the material frame 1 changes, the liquid inside the material frame is discharged from the through groove 10, thereby improving the use effect of the material frame 1; when the limit plate 5 is displaced, the slider 14 moves in the slide groove 11 to ensure its stability, and prevents the limit plate 5 from tilting during displacement, thereby further improving the stability and reliability of the limit plate 5 when in use.
