DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1-4, A multi - stage filtration treatment device for pigment production wastewater, including a filtration tank 1. At the bottom end on the right side of the filtration tank 1, there is a treatment tank 14. At the bottom end on the left side of the front of the filtration tank 1, a second water pump 19 is installed. The output end and the input end of the second water pump 19 are respectively fixedly connected with pipelines. At the top end of the inner side wall on the left side of the filtration tank 1, a reserved opening 7 is provided. At the top end on the left side of the filtration tank 1, there is a sewage discharge structure for convenience;

[0026] The sewage discharge structure includes a spiral conveyor shaft 3, a guide plate 4, and a first motor 6. At the top end on the left side of the filtration tank 1, a collection shell 2 is fixedly connected. At the top of the collection shell 2, a first motor 6 is installed. The output end of the first motor 6 is fixedly connected with a connecting shaft 5. The bottom end of the connecting shaft 5 is fixedly connected with a spiral conveyor shaft 3. At the bottom end inside the collection shell 2, a sewage discharge opening 20 is provided. At both ends at the top of the sewage discharge opening 20, guide plates 4 are fixedly connected;

[0027] The collection shell 2 is arranged on the left side of the reserved opening 7. The spiral conveyor shaft 3 rotates inside the sewage discharge opening 20. Both sides of the pipeline respectively penetrate inside the filtration tank 1 and the treatment tank 14. At the bottom end on the right side of the treatment tank 1, a drain pipe 16 is fixedly connected. At the front end of the drain pipe 16, a valve is installed;

[0028] Specifically, as Figure 1 and Figure 2 shown, impurities enter the inside of the collection shell 2 through the reserved opening 7. The guide plates 4 inside the collection shell 2 guide the impurities, so that the impurities are introduced into the inside of the sewage discharge opening 20. Then, the first motor 6 is started. The first motor 6 drives the spiral conveyor shaft 3 to rotate inside the sewage discharge opening 20 through the connecting shaft 5. Thus, the impurities can be pushed to discharge from the bottom end of the sewage discharge opening 20. When the spiral conveyor shaft 3 rotates inside the sewage discharge opening 20, it can not only improve the sewage discharge efficiency, but also prevent the impurities from blocking inside the sewage discharge opening 20.

[0029] Embodiment 2: Inside the reserved opening 7, a filter plate 9 is movably hinged. At both ends at the top of the filter plate 9, side plates 8 are fixedly connected. The filter plate 9 is arranged at the top end inside the filtration tank 1. There are three groups of filter plates 9. On both sides between the filter plates 9, connecting rods 10 are fixedly connected. At the left side of the back end of the filtration tank 1, a third motor 24 is installed. The output end of the third motor 24 is fixedly connected with a rotating shaft 25. Outside the rotating shaft 25, a top block 11 is fixedly connected. The top block 11 is arranged on the right side at the bottom end of the filter plate 9;

[0030] Specifically, as Figure 1 and Figure 4As shown, the connecting rod 10 connects the three groups of filter plates 9 together. When it is necessary to process the impurities on the filter plate 9, the third motor 24 is started. The third motor 24 drives the top block 11 to rotate through the rotating shaft 25, so that the top block 11 abuts against the right side of the bottom end of the filter plate 9, thereby raising the right side of the filter plate 9. The impurities on the filter plate 9 fall into the interior of the collection shell 2 through the reserved port 7, preventing the impurities from being on the top of the filter plate 9 and causing the filter holes inside the filter plate 9 to be blocked by the impurities, which affects the filtration efficiency.

[0031] Embodiment 3: A second motor 15 is installed on the right side of the treatment tank 14. The output end of the second motor 15 is fixedly connected to a stirring shaft 18. Stirring rods 17 are fixedly connected to the upper and lower ends of the stirring shaft 18. The stirring shaft 18 is arranged inside the treatment tank 14. A water tank 12 is arranged at the top of the treatment tank 14. A first water pump 13 is installed at the front end of the water tank 12. The output end and the input end of the first water pump 13 are respectively fixedly connected to a connecting pipe 21. The bottom end of the connecting pipe 21 is fixedly connected to a branch pipe 22. A spray head 23 is installed at the bottom end of the branch pipe 22. The branch pipe 22 is arranged at the top end inside the treatment tank 14. The top end of the connecting pipe 21 penetrates inside the water tank 12;

[0032] Specifically, as Figure 1 and Figure 3 shown, the second motor 15 drives the stirring rod 17 to rotate inside the treatment tank 14 through the stirring shaft 18, so that the sewage and the treatment liquid are mixed evenly. When it is necessary to clean the stirring rod 17 and the stirring shaft 18, the first water pump 13 is started. The first water pump 13 pumps the water inside the water tank 12 into the branch pipe 22 through the connecting pipe 21, and then sprays it onto the stirring rod 17 and the stirring shaft 18 through the spray head 23 to clean the stirring shaft 18 and the stirring rod 17.

[0033] Working principle: When the utility model is in use, the connecting rod 10 connects the three groups of filter plates 9 together. The filter plates 9 can filter sewage, and the impurities on the sewage will be filtered to the top of the filter plates 9. When it is necessary to process the impurities on the filter plates 9, the third motor 24 is started. The third motor 24 drives the top block 11 to rotate through the rotating shaft 25, so that the top block 11 abuts against the right side of the bottom end of the filter plate 9, thereby raising the right side of the filter plate 9. The impurities on the filter plate 9 fall into the interior of the collection shell 2 through the reserved port 7. The guide plate 4 inside the collection shell 2 guides the impurities, causing the impurities to be introduced into the interior of the sewage discharge port 20. Then, the first motor 6 is started. The first motor 6 drives the screw conveyor shaft 3 to rotate inside the sewage discharge port 20 through the connecting shaft 5, thereby pushing the impurities to discharge from the bottom end of the sewage discharge port 20. Rotating the screw conveyor shaft 3 inside the sewage discharge port 20 can not only improve the sewage discharge efficiency but also prevent the impurities from clogging inside the sewage discharge port 20. The second motor 15 drives the stirring rod 17 to rotate inside the treatment tank 14 through the stirring shaft 18, making the sewage and the treatment liquid mix evenly. When it is necessary to clean the stirring rod 17 and the stirring shaft 18, the first water pump 13 is started. The first water pump 13 pumps the water inside the water tank 12 into the branch pipe 22 through the connecting pipe 21, and then sprays it onto the stirring rod 17 and the stirring shaft 18 through the nozzle 23 to clean the stirring shaft 18 and the stirring rod 17.
