[0029] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] Refer to Figures 1-5 As shown, the first embodiment of the present application provides a sedimentation and filtration device for an ecological tailwater treatment system, comprising at least one brush treatment pool 1, in which multiple rows of equidistant brush members 2 are installed. The multiple rows of brush members 2 each include a connecting frame 3, which is higher than the water level of the brush treatment pool 1. The connecting frame 3 is evenly distributed with multiple filter brushes 4 on the connecting frame 3, and the filter brushes 4 are used to intercept organic matter in the pool. Multiple expansion pools 5 or a main expansion pool 5 are opened on the side of the brush treatment pool 1. The expansion pool 5 and the brush treatment pool 1 are interconnected through a first opening 6, and the first opening 6 allows the filter brushes 4 to enter the expansion pool 5.

[0031] Since the brush in the prior art is hung on a hanging rod, which is then placed on a steel frame, when the brush needs to be cleaned, the brush is taken out of the hanging rod and cleaned, and then reinstalled on the hanging rod. First of all, there are a large number of brushes in the entire brush treatment pool 1, and some brush treatment pools 1 are deep, resulting in a long overall length of the brush, which requires great strength for manual removal or cleaning. Therefore, the present application improves it; specifically, the connecting frame 3 includes a straight section 7 and a flat spiral section 8. The connection between the flat spiral section 8 and the straight section 7 is detachable, and the detachable connection is preferably a snap connection. The straight section 7 is provided with a protrusion on the end face facing the flat spiral section 8, and the straight section 7 is provided with a bayonet corresponding to the protrusion. Both the straight section 7 and the flat spiral section 8 are provided with a track 9 for sliding the filter brush 4. The track 9 is slidably connected with a traction push block 10. The traction push block 10 includes two mutually attractive first magnet blocks 101 and second magnet blocks 102. The first magnet block 101 is fixedly connected to the first traction rope 11. The first traction rope 11 is provided with a first winding end 111. The second magnet block 102 is fixedly connected to the second traction rope 12. The first magnet block 101 and the second magnet block 102 are both connected to the guide sliding connection of the side wall of the track 9. The reason for setting the traction push block 10 as the first magnet block 101 and the second magnet block 102 is to adapt to the detachability of the straight section 7 and the flat spiral section 8, thereby ensuring the switching back and forth between the collection and reset of the filter brush 4. The first reel-up end 111 and the second reel-up end 121 are preferably motor-driven traction rope reeling. When the first reel-up end 111 rotates forward to start the reeling of the first traction rope 11, the second reel-up end 121 reverses to start the coiling of the second traction rope 12, thereby realizing the first magnet block 101 to move the filter brush 4 to the flat spiral section 8, and transform the horizontal setting of the filter brush 4 into a reeling setting. The first magnet block 101 is restricted by the reeling length of the first traction rope 11 to limit the unfolding of the filter brush 4, and reel the filter brush 4 in At the same time, the filter brush 4 is taken out of the expansion pool 5 for cleaning: all the filter brushes 4 can be taken out by pulling the flat spiral section 8 and the filter brushes 4 are rolled up and gathered together for easy cleaning. The filter brush 4 is rinsed from multiple angles by a high-pressure water gun. After rinsing, the flat spiral section 8 with the filter brush 4 is placed back into the expansion pool 5, and the first magnet block 101 and the second magnet block 102 are re-attracted, the second winding end 121 is started to rotate forward, and the first winding end is reversed to make the filter brush 4 return to the straight section 7.

[0032] like Figure 3 、 Figure 4As shown, in order to keep the adjacent spacing of the filter brush 4 consistent after returning to the flat section 7, and to be able to roll onto the flat spiral section 8 when the filter brush 4 needs to be cleaned, a spacing adjusting member 13 is arranged between adjacent filter brushes 4. The spacing adjusting member 13 includes V-shaped articulated rods 131 arranged between adjacent filter brushes 4, the ends of the V-shaped articulated rods 131 are rotatably connected to adjacent filter brushes 4, and a reset telescopic part 132 is arranged between the V-shaped articulated rods 131. The reset telescopic part 132 is used to restore the original adjacent spacing when the adjacent spacing of the filter brush 4 is compressed and rearranged during cleaning, thereby reducing manual adjustment of the spacing of the filter brush 4. The reset telescopic part 132 includes arc-shaped telescopic blocks arranged between the V-shaped articulated rods 131, and telescopic springs arranged between the arc-shaped telescopic blocks. The reset telescopic part 132 is prior art and will not be described in detail here.

[0033] As shown in FIG. 1, Figures 6-9 The second embodiment provided by the present application is basically the same as the first embodiment, and the only difference is that the connecting frame 3 includes a flat section 7 and a flat spiral section 8, the flat section 7 and the flat spiral section 8 are integrally formed, and the flat section 7 and the flat spiral section 8 are installed in the brush treatment tank 1 and the expansion tank 5 through limiting members.

[0034] The first opening 6 is provided with a telescopic water baffle 14 for blocking the communication between the expansion tank 5 and the brush treatment tank 1.

[0035] The plurality of expansion tanks 5 are provided with a water drainage pipeline 18 for draining tail water in the expansion tank 5 back into the brush treatment tank 1, and a drainage and washing member 17 is arranged between the plurality of expansion tanks 5 for washing the filter brush 4.

[0036] The expansion tank 5 is provided with a brush cleaning member 15, the brush cleaning member 15 includes a plurality of filter plates combined to form a shell cavity 151 with a flat spiral, the shell cavity 151 is provided with an inclined plate 152 facing the filter brush 4 at the upper end, the end of the inclined plate 152 is transversely provided with cleaning brush or cleaning roller, and the shell cavity 151 is provided with a lifting member 16 between the shell cavity 151 and the expansion tank 5, the lifting member 16 is used to lift the shell cavity 151.

[0037] The above specific improvements, in order to reduce the back and forth movement of the filter brush 4, set up in the extension pool 5 to clean the filter brush 4, so the flat section 7 and the flat spiral section 8 in the connecting frame 3 can be set as one body, installed on the brush processing pool 1 and the extension pool 5 by the limiting piece, which includes steel frame or other objects that can support the connecting frame 3. Of course, the detachable connecting mode of the connecting frame 3 in example one can also be continued to be used, and the selection is made according to the actual situation. The telescopic water baffle 14 is arranged at the first opening 6, which can be used to separate the brush processing pool 1 from the extension pool 5 after the filter brush 4 is wound into the extension pool 5 by the first traction rope 11, reduce the flow exchange between the two pool bodies, so as to reduce the interception on the brush when the filter brush 4 is cleaned in the extension pool 5. According to the situation that all filter brushes 4 are cleaned together or the filter brushes 4 are cleaned in batches, it is determined whether the telescopic water baffle 14 is separately configured with a drive or the telescopic water baffles 14 on the same side are used together to realize the closing of the first opening 6 on the same side to clean the filter brush 4. Further, the drain pipeline 18 is arranged between the brush processing pool 1 and the extension pool 5, which is used to drain the tail water in the extension pool 5 back to the brush processing pool 1. The brush cleaning piece 15 is arranged in the extension pool 5, which includes a plurality of filter plates spliced to form a shell cavity 151 with a flat spiral, an inclined plate 152 towards the filter brush 4 is arranged at the upper end of the shell cavity 151, a cleaning brush or a cleaning roller is transversely arranged at the end of the inclined plate 152, the cleaning brush and the cleaning roller are both made of flexible material, and the lifting piece 16 is arranged between the shell cavity 151 and the extension pool 5, which is a lead screw drive or other lifting piece 16 that can realize the vertical linear motion of the shell cavity 151. When the brush cleaning piece 15 is cleaned, the extension pool 5 is provided with the drainage and spray cleaning piece 17, which includes a drainage pipeline for the water in the tail water system that can be used for cleaning the brush, and a high-pressure spray head arranged on the extension pool 5 after the drainage to wash the filter brush 4. At the same time of the upward cleaning of the inclined plate 152, the cleaning brush or the cleaning roller, the high-pressure spray head washes the filter brush 4 downward, so that the interception on the filter brush 4 is collected into the shell cavity 151 to the greatest extent, and the interception in the shell cavity 151 is cleaned subsequently. In this way, manual cleaning is not required, and the corresponding components can be started by the controller to clean them, and the traction driving block 10 is started to move after the cleaning is completed, so that the filter brush 4 returns to the brush processing pool 1.
