[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] Combined with Figure 1-3 The utility model provides a filtering device for wastewater treatment, including a treatment box 1, the upper end of the treatment box 1 is connected with an inlet pipe 11, the lower end of the treatment box 1 is connected with an outlet pipe 12, a pushing mechanism 2 is rotatably connected to the top center position in the treatment box 1, a coarse screening mechanism 3 is fixedly connected under the pushing mechanism 2 in the treatment box 1, and two collecting mechanisms 4 are movably connected under the coarse screening mechanism 3 in the treatment box 1, the pushing mechanism 2 includes a motor 21, a rotating shaft 22, a connecting rod 23, and a pushing rod 24, the motor 21 is fixedly connected to the center position on the treatment box 1, the output shaft of the motor 21 passes through the top of the treatment box 1 and is fixedly connected to the rotating shaft 22, the lower end of the rotating shaft 22 is fixedly connected to the connecting rod 23, and a plurality of pushing rods 24 are rotatably sleeved on the side of the connecting rod 23, and when filtering the wastewater, the motor 21 drives the rotating shaft 22 and the connecting rod 23 to rotate. The connecting rod 23 rotates, so that the pushing rod 24 under the connecting rod 23 rotates on the coarse screening mechanism 3. The pushing rod 24 uses its own vertical downward gravity to push the large garbage into the collecting mechanism 4 during the rotation around the rotating shaft 22. The collecting mechanism 4 includes a microfilter 41, a partition net 42, and a collecting bucket 43. The collecting bucket 43 is in contact with the inner wall of the treatment box 1. The partition net 42 is vertically arranged in the collecting bucket 43 and is fixedly connected to both ends of the collecting bucket 43. The microfilter 41 is located on one side of the partition net 42 and is connected to the bottom surface of the collecting bucket 43. The microfilter 41 is a semicircle that is in contact with the inner wall of one side of the treatment box 1. After the coarse screening mechanism 3 filters, the microfilter 41 further filters the wastewater and intercepts fine impurities on the microfilter 41. During the filtration process, one of the collecting mechanisms 4 can be pulled out without affecting the filtration.

[0025] Embodiment 2

[0026] Combined with Figure 1-3On the basis of the first embodiment, the coarse screening mechanism 3 includes a coarse screening mesh 31, a connecting plate 1 32, and a connecting plate 2 33. The coarse screening mesh 31 is a semicircular shape that fits the inner wall of one side of the processing box 1 and is connected to the inner wall of one side of the processing box 1. One side of the connecting plate 1 32 and the connecting plate 2 33 are respectively connected to the two ends of the coarse screening mesh 31. The top surfaces of the connecting plate 1 32 and the connecting plate 2 33 are provided with a slope inclined to one side. The coarse screening mesh 31 can intercept large garbage on the coarse screening mesh 31. The connecting plate blocks the wastewater to prevent excessive water from flowing into the collecting mechanism 4. A handle 44 is fixedly connected to one side of the collecting bucket 43. A hole adapted to the collecting mechanism 4 is provided on one side of the processing box 1 to facilitate the collection bucket 43 to be drawn out from the processing box 1. A rotating ring 25 is provided at the top of the pushing rod 24. The rotating ring 25 is rotatably connected to the connecting rod 23 to adapt to the slope of the connecting plate.

[0027] The working principle of the present application is as follows: when filtering wastewater, the motor 21 drives the rotating shaft 22 and the connecting rod 23 to rotate, so that the connecting rod 23 pushes the material rod 24 downward to rotate on the coarse screen 31, and pushes the large garbage into the corresponding position of the collecting bucket 43 in the collecting mechanism 4. The microfilter 41 further filters the wastewater and intercepts the fine impurities on the microfilter 41. During the filtering process, the filtered material can be processed by pulling out the upper collecting mechanism 4. The filtering device uses the lower collecting mechanism 4 for filtering without affecting the filtering process. A partition net 42 is provided in the collecting bucket 43 to classify and collect large garbage and fine debris, so as to facilitate the subsequent further processing of garbage and debris.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
