[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 4 As shown, this utility model embodiment provides a high-efficiency decolorizing and filtering device, including a decolorizing box 1, an elastic component 11, and a water supply component 12; a sewage pipe 2 and a decolorizing pipe 3 are respectively connected to one side of the decolorizing box 1; a filter screen 4 is fixed inside the decolorizing box 1; a drive motor 5 is fixed to the top of the decolorizing box 1; a first stirring shaft 6 that rotates through the filter screen 4 is fixed to the output shaft of the drive motor 5; a rotating plate 7 located above the filter screen 4 is fixed to the outer wall of the first stirring shaft 6; a cleaning brush 8 that abuts against the filter screen 4 is provided at the bottom end of the rotating plate 7; a spray pipe 9 located below the filter screen 4 is fixed to the outer wall of the first stirring shaft 6; a plurality of nozzles 10 facing the filter screen 4 are obliquely connected to the top end of the spray pipe 9; the elastic component 11 is disposed between the rotating plate 7 and the cleaning brush 8 for driving the elastic movement of the cleaning brush 8; the water supply component 12 is disposed at the bottom end of the decolorizing box 1 and is connected to the spray pipe 9 for supplying water to the spray pipe 9.

[0019] In this embodiment, wastewater is discharged into the decolorization tank 1 through the wastewater pipe 2. First, the waste material in the wastewater is filtered through the filter screen 4. Then, the wastewater flows to the bottom of the decolorization tank 1, where a decolorizing agent is added. The specific composition of the decolorizing agent can be adjusted according to different types of wastewater. This process decolorizes and filters the wastewater. After treatment, the wastewater is discharged through the drain outlet at the bottom of the decolorization tank 1. When a large amount of waste material adheres to the filter screen 4, the decolorization tank 1 is emptied. Then, the water supply assembly 12 is connected to an external water source, allowing the water supply assembly 12 to supply water to the spray pipe 9. The water is then sprayed through the nozzle 10 onto the bottom of the filter screen 4. The water sprayed from the nozzle 10 can rinse the filter screen 4 from bottom to top. Under the action of reverse rinsing, the waste material on the filter screen 4 can be fully rinsed onto the surface of the filter screen 4. Then, with the cooperation of the elastic component 11, the cleaning brush 8 is driven to move elastically, so that the cleaning brush 8 can fully contact the surface of the filter screen 4, and the waste material on the surface of the filter screen 4 can be scraped and cleaned. Then, as the drive motor 5 drives the first stirring shaft 6 to rotate, the cleaning brush 8 and the nozzle 10 can rotate circumferentially, so as to fully clean the filter screen 4, reduce the residue of waste material on the surface of the filter screen 4, facilitate the use of the filter screen 4 for filtration, and thus facilitate the treatment of sewage and improve the sewage treatment efficiency.

[0020] In a further embodiment, such as Figure 4As shown, the elastic component 11 includes two connecting rods 111, both of which are hinged to the top of the cleaning brush 8. The top of each of the two connecting rods 111 is hinged to a slider 112. The bottom of the rotating plate 7 is provided with a groove 113 for the slider 112 to slide. Both sides of the inner wall of the groove 113 are elastically connected to the slider 112 by springs 114.

[0021] In this embodiment, under the elastic action of the spring 114, the slider 112 is driven to move elastically. The slider 112 drives the connecting rod 111 to move elastically, and the connecting rod 111 can drive the cleaning brush 8 to move elastically, so that the cleaning brush 8 can fully contact the surface of the filter screen 4, which facilitates the cleaning brush 8 to clean the surface of the filter screen 4.

[0022] In a further embodiment, such as Figure 3 As shown, the water supply assembly 12 includes a connecting pipe 121, which is fixedly installed inside the first stirring shaft 6 and connected to the spray pipe 9. The bottom end of the connecting pipe 121 is connected to a rotary joint 122, and the bottom end of the decolorizing box 1 is fixed with a water pump 123 connected to the rotary joint 122.

[0023] In this embodiment, the water pump 123 is connected to an external water source, and the rotary joint 122 allows the connecting pipe 121 and the water pump 123 to be in a rotating state. The first stirring shaft 6 is hollow, which facilitates the placement of the connecting pipe 121 inside the first stirring shaft 6, thus facilitating the normal rotation of the first stirring shaft 6 and avoiding interference with its movement. Under the operation of the water pump 123, the external water source can be transported, and the external water source is transported to the spray pipe 9 through the rotary joint 122 and the connecting pipe 121, and then sprayed out through the nozzle 10 to rinse the surface of the filter screen 4.

[0024] In a further embodiment, such as Figure 2 As shown, a plurality of first stirring blades 13 located below the filter screen 4 are fixed on the outer wall of the first stirring shaft 6. Two second stirring shafts 14 located on both sides of the first stirring shaft 6 are rotatably connected inside the decolorizing box 1. A plurality of second stirring blades 15 are fixed on the outer wall of each of the two second stirring shafts 14. A support box 16 that rotates with the first stirring shaft 6 and the second stirring shaft 14 is fixed inside the decolorizing box 1. A linkage component 17 that drives the second stirring shaft 14 to move is provided inside the support box 16.

[0025] In this embodiment, after the decolorizing agent is added to the wastewater through the decolorizing pipe 3, the drive motor 5 drives the first stirring shaft 6 and the first stirring blade 13 to rotate. At the same time, with the cooperation of the linkage component 17, the second stirring shaft 14 and the second stirring blade 15 can be driven to rotate. In this way, with the cooperation of the first stirring shaft 6, the first stirring blade 13, the second stirring shaft 14 and the second stirring blade 15, the wastewater and the decolorizing agent can be fully mixed, thereby facilitating the full decolorization of the wastewater and improving the decolorization effect of the wastewater.

[0026] In a further embodiment, such as Figure 3 As shown, the linkage assembly 17 includes two first synchronous pulleys 171, both of which are sleeved on the outer wall of the first stirring shaft 6, and both of the outer walls of the two second stirring shafts 14 are sleeved with second synchronous pulleys 172. The two first synchronous pulleys 171 are respectively connected to the second synchronous pulleys 172 via synchronous belts 173.

[0027] In this embodiment, when the drive motor 5 drives the first stirring shaft 6 and the first stirring blade 13 to rotate, the first stirring shaft 6 drives the first synchronous wheel 171 to rotate. The first synchronous wheel 171 drives the second synchronous wheel 172 to rotate through the synchronous belt 173. The second synchronous wheel 172 can then drive the second stirring shaft 14 and the second stirring blade 15 to rotate, thereby facilitating the thorough mixing of sewage and decolorizing agent and ensuring thorough decolorization of sewage. Furthermore, the first synchronous wheel 171, the second synchronous wheel 172, and the synchronous belt 173 are all housed inside the support box 16 for easy protection and to prevent corrosion from sewage.

[0028] In a further embodiment, such as Figure 3 As shown, the first stirring blade 13 and the second stirring blade 15 are arranged alternately.

[0029] In this embodiment, the staggered arrangement of the first stirring blade 13 and the second stirring blade 15 avoids dead corners during the stirring and mixing process, facilitating the thorough mixing of wastewater and decolorizing agent.

[0030] The working principle of this high-efficiency decolorizing filtration device is as follows: Wastewater is discharged into the decolorizing tank 1 through the wastewater pipe 2. First, the waste in the wastewater is filtered through the filter screen 4. Then, the wastewater flows to the bottom of the decolorizing tank 1. Decolorizing agent is then added into the decolorizing tank 1 through the decolorizing pipe 3. Under the movement of the drive motor 5, the first stirring shaft 6 and the first stirring blade 13 are rotated. The first stirring shaft 6 drives the first synchronous wheel 171 to rotate. The first synchronous wheel 171 drives the second synchronous wheel 172 to rotate through the synchronous belt 173. The second synchronous wheel 172 then drives the second stirring shaft 14 and the second stirring blade 15 to rotate. In this way, with the cooperation of the first stirring shaft 6, the first stirring blade 13, the second stirring shaft 14 and the second stirring blade 15, the wastewater and the decolorizing agent are easily and thoroughly mixed, thereby facilitating the thorough decolorization of the wastewater and improving the decolorization effect. After the treatment is completed, the wastewater is discharged through the drain at the bottom of the decolorizing tank 1. When a large amount of waste adheres to the filter screen 4, the decolorizing tank 1 is emptied first. The water pump 123 is then connected to an external water source. Under the operation of the water pump 123, the external water source is transported through the rotary joint 122 and connecting pipe 121 to the spray pipe 9, and then sprayed out through the nozzle 10 to rinse the surface of the filter screen 4. Under the elastic action of the spring 114, the slider 112 is driven to move elastically. The slider 112 drives the connecting rod 111 to move elastically, which in turn drives the cleaning brush 8 to move elastically, ensuring that the cleaning brush 8 makes full contact with the surface of the filter screen 4. Then, as the drive motor 5 drives the first stirring shaft 6 to rotate, the cleaning brush 8 and the nozzle 10 rotate circumferentially, thus thoroughly cleaning the filter screen 4, reducing the residue of waste on the surface of the filter screen 4, facilitating the use of the filter screen 4 for filtration, thereby facilitating the treatment of sewage and improving the efficiency of sewage treatment.
