DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1-Figure 2As shown, the printing and dyeing wastewater treatment mechanism includes a bracket 1 and a conveying pipe 6 arranged on the bracket 1 for inputting printing and dyeing wastewater, and the conveying pipe 6 can convey the wastewater generated in the printing and dyeing workshop; two discs 4 are arranged on the bracket 1, and the two discs 4 are connected by two symmetrically arranged arc-shaped separators 11, one of the discs 4 is connected to the transmission shaft 3, and the transmission shaft 3 is also connected to a driving structure that can make it rotate, and two filter screen assemblies are symmetrically arranged between the two discs 4, and the filter screen assemblies are used in conjunction with the arc-shaped separator 11, and the bottom of the arc-shaped separator 11 has an outlet 11a, and an output pipe 10 is also horizontally fixed on the bracket 1, and a part of the output pipe 10 passes through another disc 4 and is located between the two arc-shaped separators 11, and the top of the side of the output pipe 10 has an inlet 10a that matches the outlet 11a, and in practice, an existing sealing structure can be installed at the inlet 10a.

[0018] The driving structure includes a conversion motor 15, a sprocket 14, a sprocket 2 and a chain belt 16. The conversion motor 15 is installed on the bracket 1, and the output shaft of the conversion motor 15 is arranged horizontally. The sprocket 14 is installed at the end of the output shaft of the conversion motor 15, the sprocket 2 is installed on the transmission shaft 3, and the chain belt 16 is sleeved between the sprocket 14 and the sprocket 2. With this structure, the conversion motor 15 drives the sprocket 14 to rotate, the sprocket 14 drives the sprocket 2 to rotate through the chain belt 16, the sprocket 2 drives the transmission shaft 3 to rotate, and the transmission shaft 3 can drive the disc 4 to rotate, thereby realizing the back and forth switching between the two filter screen assemblies.

[0019] A tensioning sprocket 13 matching with the chain belt 16 is also installed on the bracket 1 .

[0020] The filter screen assembly includes a fixed screen plate 9 and two movable screen plates 7. The fixed screen plate 9 is installed between two discs 4. The discs 4 have a limiting edge 8. The movable screen plate 7 is inserted into the limiting edge 8. The movable screen plate 7 and the fixed screen plate 9 form a U-shaped structure. The discs 4 are also threaded with locking screws 5 for locking the movable screen plates 7. In this embodiment, the two movable screen plates 7 can be disassembled and assembled as needed.

[0021] The locking screw 5 is a hand-tightened part.

[0022] The bracket 1 is also provided with a solid waste collection box 12. With this structure, when the filter assembly is facing downward, the solid waste filtered out can be automatically poured into the solid waste collection box 12, and manual cleaning is only required to simply clean the remaining parts.

[0023] In the utility model, the printing and dyeing wastewater is transported to the filter screen assembly through the delivery pipe 6. After the solid waste is initially filtered, the outlet 11a enters the inlet 10a and is then discharged from the output pipe 10 to the next processing step. Since two switchable filter screen groups are provided, there is no need to close the pipeline to clean the filter part.

[0024] In this embodiment, the mechanism mainly realizes the preliminary filtering treatment of the solid waste in the printing and dyeing wastewater. The solid waste collection box 12 may have some wastewater but it will not affect its normal use.
