[0021] The present utility model will be further described below with reference to the accompanying drawings.

[0022] According to Figures 1-6 As shown: The present utility model provides a wastewater treatment device for a polymer catalytic system, including a leg 1, and the leg 1 is fixedly connected upward with a treatment tank 2; a feed hole 3 is opened at the upper end of the treatment tank 2, and a discharge pipe 7 is connected to the lower end; a partition board 10 is fixedly arranged in the treatment tank 2, the upper part of the partition board 10 is a precipitation layer, the lower part of the partition board 10 is a filtration layer, and the precipitation layer and the filtration layer are communicated through a pipeline with a valve; a filtration structure is arranged in the treatment tank 2 below the partition board 10, there are two sets of upper and lower filtration structures, and the filtration structure includes two mutually spliced filter plates 11; the filter plate 11 is slidably arranged relative to the treatment tank 2, and an operation board 17 fixedly connected with the filter plate 11 is arranged on the outer wall of the treatment tank 2; a fixed hole 13 is opened on the filter plate 11, and a plugging structure inserted into the fixed hole 13 is slidably arranged in the treatment tank 2; cleaning structures corresponding to the filter plates 11 are arranged on both sides of the treatment tank 2.

[0023] The filter plate 11 is fixed through the plugging structure, which is convenient for the disassembly and installation during the cleaning of the filter plate 11; at the same time, two sets of upper and lower filter plates 11 are provided, which can ensure that the wastewater treatment process does not need to be paused when the filtration structure is disassembled and cleaned, thus ensuring the continuity of wastewater treatment.

[0024] As Figure 4 、 5 As shown, the plugging structure includes a fixed rod 12, the fixed rod 12 is slidably arranged in the treatment tank 2, and the fixed rod 12 is inserted into the fixed hole 13; fixed cylinders 14 are fixedly arranged at the upper and lower ends of the treatment tank 2, and the fixed rod 12 is located in the fixed cylinder 14. A compression plate 16 fixedly sleeved on the fixed rod 12 is arranged in the fixed cylinder 14, and a spring 15 sleeved on the fixed rod 12 is arranged in the fixed cylinder 14; the spring 15 has a reserved compression amount, which can continuously generate pressure on the compression plate 16, thereby increasing the stability of the fixed rod 12 for fixing the filter plate 11.

[0025] There are two fixed holes 13, and the two fixed holes 13 are respectively located at both ends of the filter plate 11, which can ensure that the fixed rod 12 can fix the filter plate 11 in both the installation and disassembly states.

[0026] As Figure 2 shown, the cleaning structure includes a support plate 4, a cleaning nozzle 5 communicated with an external water source, and a water receiving tank 6. The support plate 4 is fixedly arranged on both sides of the treatment tank 2. The cleaning nozzle 5 is arranged below the support plate 4 and above the two groups of filtering structures, which is convenient for cleaning the two groups of filtering structures. The water receiving tank 6 is fixedly arranged on both sides of the treatment tank 2 and below the two groups of filtering structures. The water receiving tank 6 can collect the wastewater after cleaning and prevent the sewage from flowing randomly.

[0027] As Figure 3 、 4 shown, a motor 8 is arranged on the treatment tank 2. A stirring shaft 9 located in the precipitation layer is fixedly connected to the output shaft of the motor 8, and stirring blades are fixedly connected to the stirring shaft 9. The arrangement of the stirring shaft 9 and the stirring blades can stir the precipitation layer, thereby accelerating the reaction between the reducing agent and the sewage and increasing the precipitation efficiency of solid substances.

[0028] The principle of the present utility model

[0029] As Figures 1-3 shown, when the present application works normally, the wastewater of the polymer catalytic system to be treated and the reducing agent are added from the feed hole 3, the motor 8 is started, and the stirring shaft 9 is used to mix them evenly. After the solid substances are completely precipitated, the pipeline valves of the precipitation layer and the filtering layer are opened, so that the wastewater with solid impurities enters the filtering layer. After being filtered by the filtering structure, the solid impurities remain on the filter plate 11, and the filtered wastewater finally flows out from the discharge pipe 7.

[0030] Since there are two sets of filtering structures, upper and lower, after the filtering structure is used for a long time, a lot of impurities often accumulate in the upper filtering structure, and these impurities need to be removed and the filtering structure needs to be cleaned at the same time. As Figure 4 、 5 shown, pull up the fixing rod 12 to make the fixing rod 12 disengage from the fixing hole 13, and at the same time, the compression plate 16 compresses the spring 15. Operate the operation plate 17 to directly pull out the filter plate 11. When another fixing hole 13 is aligned with the fixing rod 12, release the fixing rod 12. Under the action of the resilience of the spring 15, the fixing rod 12 is inserted into the fixing hole 13, thereby fixing the filter plate 11 again, and quickly completing the disassembly of the filter plate 11. And during the disassembly process, due to the existence of the other set of filtering structures, the filtration of the wastewater can still be ensured, and there is no need to pause the wastewater treatment process, thereby improving the efficiency of wastewater treatment. Introduce the external water source into the cleaning nozzle 5 to clean the pulled-out filter plate 11. After the cleaning, when the filter plate 11 is slid into the treatment tank 2, the filter plate 11 is still fixed by the plugging structure, and the installation of the filter plate 11 can be quickly completed.

[0031] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
