Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a sewage filtering device. Background Art

[0002] Sewage filtration equipment usually refers to the general term for various filtration equipment in the sewage purification process. During the filtration process, sewage generally needs to be filtered through multiple different media in turn to meet the standards for domestic water and be reused. In the primary filtration process, a filter is usually used to filter large-volume impurities in the sewage.

[0003] In the sewage filtering equipment used in the prior art, sewage is directly discharged through the sewage pipe and contacts the filter. However, the flow path of sewage usually remains unchanged during the flow. Therefore, the contact between sewage and the filter is not uniform, resulting in part of the filter area not being fully utilized, thereby affecting the subsequent sewage filtering effect.

[0004] In view of this, we propose a sewage filtering device. Utility Model Content

[0026] Reference Figure 1-4 The present application provides a sewage filtering device, including a filter tank 1, the bottom of the filter tank 1 is designed to be funnel-shaped, a drainage hole is opened at the bottom of the filter tank 1, a sewage pipe is connected to the drainage hole, a cover body 2 is detachably installed on the top of the filter tank 1, a liquid inlet is arranged at the center of the top of the cover body 2, a pipe 3 is installed in the liquid inlet, and the outlet end of the pipe 3 extends into the cover body 2, a filter 10 is arranged in the filter tank 1, the outer side of the filter 10 is fixed to the inner wall of the filter tank 1, and at least three filter layers are filled between the bottom of the filter 10 and the bottom of the filter tank 1, wherein the three filter layers are respectively an upper sand and gravel layer, a coarse sand layer and a lower sand and gravel layer, which are used for fine filtering of sewage.

[0027] A rotating disk 4 is rotatably connected to the center of the top of the inner wall of the cover body 2 through a bearing, a first gear 5 is fixed to the bottom end of the rotating disk 4, the rotating disk 4 and the first gear 5 are both rotatably sleeved on the outer wall of the pipe 3, an arc-shaped guide plate 6 is fixed to one side of the bottom end of the first gear 5, the arc-shaped guide plate 6 is located below the outlet of the pipe 3, and the width of the arc-shaped guide plate 6 is greater than the inner diameter of the pipe 3, the arc-shaped guide plate 6 can well catch the sewage, and a rotating component is provided on one side of the first gear 5, the rotating component is used to drive the arc-shaped guide plate 6 to rotate, so that the sewage discharged from the pipe 3 is guided and diverted by the rotation of the arc-shaped guide plate 6, so that the sewage can evenly contact the periphery of the filter 10;

[0028] Among them, the rotating component provided in the present application includes a second gear 7, which is meshed on one side of the first gear 5. A motor 9 is installed on the upper surface of the cover body 2 through a bracket. The output end of the motor 9 is fixedly connected to a rotating shaft 8 through a coupling. The bottom end of the rotating shaft 8 extends into the cover body 2 and is fixed to the top of the second gear 7. The second gear 7 is rotatably connected to the inside of the cover body 2 through a bearing. When the motor 9 controls the rotating shaft 8 and the second gear 7 to rotate, the second gear 7 can control the rotation of the first gear 5, the rotating disk 4 and the arc guide plate 6. The arc guide plate 6 rotates below one end of the pipe 3, and can guide and divert the sewage discharged through the pipe 3, so that the flow path of the sewage is changed, and the sewage is discharged to the periphery of the filter 10 in a dispersed manner, and is evenly contacted with the filter 10, thereby improving the filtering effect of the filter 10.

[0029] Reference Figure 5-6 The filter 10 provided in the present application is of bucket-shaped design. A sewage outlet is provided in the middle of the bottom end of the filter 10. A collecting cylinder 11 is detachably installed in the sewage outlet. As the arc-shaped guide plate 6 rotates to control the continuous flow of sewage, the sewage can impact the impurities filtered from the periphery of the filter 10, causing the impurities to slide into the collecting cylinder 11 for collection, thereby facilitating subsequent cleaning. The inner wall of the bottom end of the collecting cylinder 11 is provided with a plurality of filter holes, through which the filtered sewage can be conveniently discharged;

[0030] Among them, a plug-in block 12 is provided below the upper edge of the collecting barrel 11, and two sets of card grooves that cooperate with the plug-in block 12 are opened on the inner wall of the filter 10. A handle is fixed above the upper edge of the collecting barrel 11. By holding the handle upwards, the collecting barrel 11 can be easily lifted out. By providing the plug-in block 12, the collecting barrel 11 can be easily installed, wherein the upper edge of the collecting barrel 11 is flush with the inner wall of the filter 10, thereby facilitating impurities to slide into the collecting barrel 11 for collection.

[0031] The implementation principle of a sewage filtration device in the embodiment of the present application is:

[0032] First, when it is necessary to filter the sewage, the motor 9 is started to control the rotation of the rotating shaft 8 and the second gear 7. When the second gear 7 rotates, the first gear 5 and the rotating disk 4 are controlled to rotate, so that the arc guide plate 6 rotates below one end of the pipe 3. When the sewage is discharged through one end of the pipe 3, it contacts the arc guide plate 6. At this time, as the arc guide plate 6 rotates, the sewage is guided and diverted, so that the sewage contacts the filter 10 evenly. After the sewage passes through the filter 10, it contacts the three filter layers again for filtration. Finally, the filtered water is discharged through the sewage pipe.

[0033] Among them, as the sewage continues to flow, the sewage can impact the impurities filtered around the filter 10, causing the impurities to slide into the collection barrel 11 for collection. When the impurities collected in the collection barrel 11 need to be processed, the installation between the filter tank 1 and the cover body 2 is released, and then the collection barrel 11 can be lifted out by holding the handle upwards to process the impurities collected in the collection barrel 11.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
