[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] The present invention provides a filtering tank for wastewater treatment, as shown in Figure 1 , Figure 3 and Figure 4 , the filtering tank includes a pool body 1, a partition board 14 fixedly installed inside the pool body 1, a mounting plate 16 fixedly installed on the pool body 1, a water pump 2 fixedly installed on the top of the mounting plate 16, and a filtering mechanism for filtering wastewater arranged on the top of the mounting plate 16.

[0028] The filtering mechanism includes a filter box 3 fixedly installed on the top of the mounting plate 16, a filter frame 8 slidably installed inside the filter box 3, a filter plate 9 movably installed inside the filter frame 8, a slide bar 7 fixedly installed at the bottom of the filter frame 8, a support bar 5 fixedly installed inside the filter box 3, and a slide rail 6 fixedly installed on the top of the support bar 5.

[0029] The tank body 1 of the filtration tank is divided into two chambers by a partition plate 14. The first chamber is used to introduce wastewater. Through the action of a water pump 2, the wastewater inside the first chamber is transported to the inside of a filtration box 3, enabling the wastewater to be filtered through a filter plate 9. After the filtration is completed, the wastewater will flow into the second chamber of the tank body 1 for subsequent use. There are two sets of filter frames 8 and filter plates 9 inside the filtration box 3, and all related parts also have two sets. The filter frame 8 can move the filter plate 9 out of the filtration box 3 to facilitate cleaning or replacing the dirty filter plate 9. The advantage of having two sets of filter frames 8 and filter plates 9 is that they can be used alternately. And when cleaning or replacing one of the filter plates 9, there is still another filter plate 9 inside the filtration box 3 performing the filtration work, so the operation of the filtration tank will not stop due to cleaning or replacing the filter plate 9.

[0030] Further, to facilitate the staff to clean or replace the filter plate 9, as Figure 2 、 Figure 3 and Figure 6 shown, a plug post 13 is fixedly connected inside the filter frame 8. A notch adapted to the plug post 13 is provided on the filter plate 9. A handle is fixedly connected to the filter plate 9. A sliding groove for the filter frame 8 to slide is provided on the filtration box 3. A sliding strip 7 is slidably connected inside a slide rail 6, and the slide rail 6 penetrates through the filtration box 3.

[0031] The setting of the sliding strip 7 enables the filter frame 8 to move the filter plate 9 stably on the slide rail 6. The filter plate 9 is sleeved on the plug post 13 through the notch. The setting of the plug post 13 provides stability for the installation of the filter plate 9 inside the filter frame 8. The handle provided on the filter plate 9 enables the staff to conveniently install the filter plate 9 inside the filter frame 8 or take out the filter plate 9 from inside the filter frame 8.

[0032] Even further, to enable the filter frame 8 to drive the filter plate 9 to move, as Figure 2 、 Figure 3 and Figure 4 shown, a push plate 10 is fixedly connected to one side of the filter frame 8. An electric push rod 11 is fixedly connected to the filtration box 3, and the movable end of the electric push rod 11 is fixedly connected to the push plate 10.

[0033] The setting of the electric push rod 11 is used to drive the filter frame 8 to move. The filter frame 8 is connected to the push plate 10, and the electric push rod 11 is also connected to the push plate 10. After starting the electric push rod 11, the electric push rod 11 drives the push plate 10 to move, and then drives the filter frame 8 to move, so that the filter frame 8 can drive the filter plate 9 to move.

[0034] Among them, to enable the wastewater to be filtered, as Figure 2 、 Figure 3 and Figure 5As shown, a top plate 4 is fixedly connected to the top of the filtration tank 3. A first communication groove is provided on the top plate 4. The water pump 2 is connected to the inner cavity of the pool body 1 through a water pipe, and the water pump 2 is connected to the inner cavity of the filtration tank 3 through the water pipe and the first communication groove.

[0035] The water inlet and outlet of the water pump 2 are respectively connected to the first chamber of the inner cavity of the pool body 1 and the inner cavity of the filtration tank 3 through water pipes. Through the action of the water pump 2, the wastewater inside the first chamber can be transported to the inside of the filtration tank 3 for filtration, thereby realizing the filtration of the wastewater.

[0036] It should be noted that in order to enable the filtered wastewater to enter the second chamber of the pool body 1, as Figure 2 、 Figure 4 and Figure 5 shown, a baffle 12 is rotatably connected inside the filtration tank 3. A second communication groove is provided on the mounting plate 16. The inner cavity of the filtration tank 3 is connected to the inner cavity of the pool body 1 through the second communication groove. A water outlet pipe 15 is fixedly connected to the pool body 1.

[0037] One end of the baffle 12 is rotatably connected inside the filtration tank 3. The setting of the baffle 12 can automatically rotate after the filter frame 8 leaves the inside of the filtration tank 3 to close the chute on the filtration tank 3 for the filter frame 8 to slide, reducing the possibility of sewage flowing to the outside of the filtration tank 3. When the filter frame 8 returns to the filtration tank 3, it will squeeze the baffle 12 to make it rotate. At this time, the baffle 12 will be above the filter frame 8 and will not affect the operation of the filter frame 8. The inner cavity of the filtration tank 3 is connected to the inner cavity of the pool body 1. After the wastewater is filtered by the filtration tank 3, it will directly flow into the second chamber of the inner cavity of the pool body 1. The water outlet pipe 15 is connected to the second chamber, and the filtered wastewater stored in the second chamber can be used by opening the water outlet pipe 15.

[0038] Furthermore, in order to improve the stability of the slide rail 6 during operation, as Figure 1 、 Figure 2 and Figure 5 shown, a support 17 is fixedly connected to the top of the mounting plate 16. One end of the slide rail 6 passing through the filtration tank 3 is fixedly connected to the support 17.

[0039] The slide rail 6 is provided to assist the filter frame 8 to move with the filter plate 9. A part of the slide rail 6 itself is installed on the strip 5 inside the filtration tank 3. Since the filter frame 8 needs to move the filter plate 9 out of the filtration tank 3, the length of the slide rail 6 is approximately twice that of the filter frame 8, and the slide rail 6 extending outside the filtration tank 3 is fixed to the support 17. The setting of the support 17 provides stability for the whole slide rail 6.

[0040] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
