Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] like Figure 1-Figure 7 As shown, the utility model provides the following technical solutions: a DTRO guide plate assembly, comprising a plurality of adjacent guide plates 1 that are fitted together on a central pull rod, a DTRO membrane 2 that is fitted on the central pull rod is provided between adjacent guide plates 1, the guide plate 1 comprises a first semicircular clamping ring 1.1 and a second semicircular clamping ring 1.2, the end faces of the first semicircular clamping ring 1.1 and the second semicircular clamping ring 1.2 are fitted together, the first semicircular clamping ring 1.1 and the second semicircular clamping ring 1.2 are detachably connected through a connecting assembly, the surfaces of the first semicircular clamping ring 1.1 and the second semicircular clamping ring 1.2 are respectively fixedly connected with support assemblies, and the support assemblies can support the first semicircular clamping ring 1.1 and the second semicircular clamping ring 1.2.

[0029] Please combine Figure 1 As shown, during use, if the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 are deformed or damaged, they need to be replaced with new first semicircular snap ring 1.1 and second semicircular snap ring 1.2. If the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 are at both ends, you only need to unscrew the end plates at both ends. At this time, the corresponding first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 are exposed, and then the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 are removed, and replaced with new first semicircular snap ring 1.1 and the second semicircular snap ring 1.2, and then the end plates are screwed on.

[0030] When it is necessary to replace the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 in the middle part, the connecting components corresponding to the side ends of the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 are disassembled, and then the damaged first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 are removed. At this time, there is a gap between the two adjacent first semicircular snap rings 1.1 or the second semicircular snap ring 1.2, and the supporting component supports the first semicircular snap ring 1.1 or the second semicircular snap ring 1.2, effectively preventing the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 from being biased downward. Then, the new first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 are inserted into the corresponding positions, and then the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 are connected and fixed through the connecting component, thereby realizing the replacement of the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2, without having to remove the other guide plates at the upper or lower end of the guide plate, thereby reducing the working intensity.

[0031] The inner ring cross-section of the first semicircular clamping ring 1.1 and the second semicircular clamping ring 1.2 is an outwardly protruding arc surface, and the inner side wall cross-section of the outer ring of the first semicircular clamping ring 1.1 and the second semicircular clamping ring 1.2 is an inwardly concave arc surface, which reduces the resistance to the flow of sewage, thereby reducing the impact force on the first semicircular clamping ring 1.1 and the second semicircular clamping ring 1.2 and improving the service life of the first semicircular clamping ring 1.1 and the second semicircular clamping ring 1.2.

[0032] Please combine Figure 2 、 Figure 5 、 Figure 6 As shown, an embodiment of the connecting component, the connecting component includes a positioning pin 3 fixed at both ends of the first semicircular snap ring 1.1, the positioning pin 3 is inserted into the positioning groove 4, the positioning groove 4 is opened at both ends of the second semicircular snap ring 1.2, and the side wall of the second semicircular snap ring 1.2 is symmetrically provided with two positioning holes 5 communicating with the positioning groove 4, and the side wall of the positioning pin 3 is provided with a pin hole 6, and the positioning hole 5 is communicated with the pin hole 6. The first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 are detachably connected by a pin 7 that passes through the positioning hole 5 and the pin hole 6 in sequence.

[0033] Please combine Figure 1 As shown, during use, when it is necessary to disassemble and assemble the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2, pull out the corresponding pin 7, and then take out the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 to replace them with new first semicircular snap ring 1.1 and the second semicircular snap ring 1.2. The new first semicircular snap ring 1.1 drives the positioning pin 3 to move and insert into the positioning groove 4. At this time, the positioning hole 5 and the pin hole 6 correspond exactly to each other. The pin 7 is passed through the positioning hole 5 and the pin hole 6 in turn to limit the positioning pin 3, thereby realizing the connection and fixation of the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2.

[0034] The planes where the two ends of two adjacent first semicircular clamping rings 1.1 are located are not in the same vertical plane.

[0035] Please combine Figure 1 As shown, during use, when the first semicircular snap ring 1.1 in the middle part is taken out in turn and a new first semicircular snap ring 1.1 is inserted, and the old second semicircular snap ring 1.2 is taken out and a new second semicircular snap ring 1.2 is inserted, the corresponding first semicircular snap ring 1.1 and second semicircular snap ring 1.2 can respectively provide auxiliary support to the second semicircular snap ring 1.2 and the first semicircular snap ring 1.1, effectively preventing the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2 at the top from being biased downward.

[0036] Please combine Figure 1-Figure 7 As shown, the support assembly embodiment, the support assembly includes two grooves 12, the grooves 12 are respectively opened on the bottom and top surfaces of the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2, the two grooves 12 are communicated, and a T-shaped slide bar 9 is fitted and slid in the groove 12, one end of the two T-shaped slide bars 9 is fitted and slid, and the other end of the T-shaped slide bar 9 passes through the slide groove 8.

The first semicircular snap ring 1.1 drives the groove 12 to slide and pushes the T-shaped slide bar 9 to move and squeeze the compression spring 11 to deform. When the first semicircular snap ring 1.1 is taken out, the top end of the first semicircular snap ring 1.1 and the T-shaped slide bar 9 at the bottom end are fitted again, as shown in FIG. Figure 7As shown, the support for the first semicircular snap ring 1.1 at the top is achieved, and then a new first semicircular snap ring 1.1 is inserted. The arc surface of the inner ring of the first semicircular snap ring 1.1 pushes the two T-shaped slide bars 9 to move in opposite directions. When the groove 12 on the new first semicircular snap ring 1.1 corresponds to the T-shaped slide bar 9, the two T-shaped slide bars 9 are inserted into the groove 12 and one end is fitted together. Then, the second semicircular snap ring 1.2 is replaced in the above manner, and finally, the pin 7 is inserted into the positioning hole 5 and the pin hole 6 to fix the first semicircular snap ring 1.1 and the second semicircular snap ring 1.2.

The obtuse angle formed by the hypotenuses of the two right-angled trapezoids in the longitudinal section of the groove 12 is 140°-170°.

[0040] This facilitates the T-shaped slide bar 9 to slide in the groove 12 .

[0041] A plurality of protrusions 13 are fixedly connected to the surfaces of the first semicircular clamping ring 1.1 and the second semicircular clamping ring 1.2, and the directions of the protrusions 13 are different.

[0042] Please combine Figure 6 As shown, during use, the arrangement of the plurality of ridges 13 can change the flow direction of sewage, reduce the impact force on the guide plate 1 and the DTRO membrane 2, protect the integrity of the guide plate 1 and the DTRO membrane 2, and extend their service life.
