Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device. Background Art

[0002] The roof of the garage sometimes forms a large amount of stagnant water due to precipitation. When the accumulated water rises to a certain height, it will not only cause a certain amount of pressure on the garage roof, but also cause a certain amount of erosion on the garage roof. Long-term accumulation of water will also cause rainwater to penetrate the garage roof. Generally, the drainage of the accumulated water on the garage roof is collected by siphoning away. The siphon principle is to use the principle of pressure difference. In a closed container, the liquid height is the same and the pressure is equal. The siphon tube is filled with water and there is no air. The water level at the incoming water end is high, and the outlet is closed with a palm or other object. At this time, the pressure in the tube is equal everywhere. After everything is arranged, open the outlet. Although the atmospheric pressure on both sides is equal, the water level at the incoming water end is high and the pressure is strong, which pushes the incoming water to flow out of the outlet continuously.

[0003] In the existing filtering device, filtering is generally performed by setting a filter net inside the device, but the filtering area of ​​the filter net is small, the filtering effect is insufficient, and the mesh is prone to clogging during long-term use. In addition, it is not convenient to clean the surface of the filter net in the existing filtering device, and it is not convenient to discharge the cleaned dirt, which affects the filtering effect. For this reason, we propose a filtering device. Utility Model Content

[0020] See also Figure 1-5 The utility model provides a technical solution: a filtering device, comprising a mounting frame 1, in which a first filtering mechanism 2 and a second filtering mechanism 3 are symmetrically fixedly installed.

[0021] The first filter mechanism 2 and the second filter mechanism 3 both include a fixed cylinder 19, a first filter cylinder 16, a connecting cylinder 9 and a second filter cylinder 10. The fixed cylinder 19 is symmetrically fixedly connected inside the mounting frame 1.

The end of the rotating shaft 6 is fixedly connected to the first filter cylinder 16. The bottom of the inner wall of the fixed cylinder 19 is rotatably connected to the supporting cylinder 18. The top of the supporting cylinder 18 is communicated with the interior of the first filter cylinder 16. The bottom of the supporting cylinder 18 passes through the fixed cylinder 19. The bottom of the fixed cylinder 19 is fixedly connected to the connecting cylinder 9. The top of the inner wall of the connecting cylinder 9 is fixedly connected to the second filter cylinder 10. The bottom of the supporting cylinder 18 extends into the second filter cylinder 10. The bottom end of the connecting cylinder 9 is connected to the purified water outlet pipe 14.

[0022] It should be noted that when the utility model is used, the mounting bracket 1 is installed in the use position, the water is siphoned into the water inlet main pipe 5, the electric control valve 15 on the water inlet pipe 4 of the first filter mechanism 2 is closed through the control system arranged in the device, and the water flows into the fixed cylinder 19 of the second filter mechanism 3 through the water inlet pipe 4 on the second filter mechanism 3, and into the space between the outer side of the first filter cylinder 16 and the inner wall of the fixed cylinder 19. The water in the fixed cylinder 19 is filtered once through the first filter cylinder 16, and the filtered water is placed in the first filter cylinder 16. Then the water in the first filter cylinder 16 enters the second filter cylinder 10 through the supporting cylinder 18, and is filtered twice through the second filter cylinder 10. The filtered water reaches the area between the outer side of the second filter cylinder 10 and the inner wall of the connecting cylinder 9, and is finally discharged and collected through the clean water outlet pipe 14. When the second filter cylinder 10 and the first filter cylinder 16 on the second filter mechanism 3 need to be cleaned after long-term use, the electric control valve 15 on the water inlet pipe 4 of the second filter mechanism 3 is closed. The electric control valve 15 is then opened on the water inlet pipe 4 of the first filter mechanism 2, and filtering is performed through the first filter mechanism 2. When the second filter cartridge 10 and the first filter cartridge 16 are cleaned, the motor 7 on the fixed cylinder 19 of the second filter mechanism 3 is controlled to work, and the first filter cartridge 16 is driven to rotate. During the rotation process of the first filter cartridge 16, the outer side of the first filter cartridge 16 contacts the cleaning brush rod 8, and the brush on the cleaning brush rod 8 brushes the outer side of the first filter cartridge 16 to scrape off the dirt on the first filter cartridge 16. The electric control valve 15 on the first sewage outlet 13 is only needed to discharge the dirt. During the control process of the first filter cartridge 16 rotating, the rotating rod 11 rotates with the first filter cartridge 16, and the dirt removal brush 12 on the rotating rod 11 continuously brushes the inner wall of the second filter cartridge 10, so that the dirt is placed at the bottom end of the second filter cartridge 10. At this time, the electric control valve 15 on the second sewage outlet 17 is opened, so that the dirt in the second filter cartridge 10 can be discharged, thereby realizing the cleaning of the second filter cartridge 10 and the first filter cartridge 16.

[0023] A rotating rod 11 is fixedly connected to the top of the inner wall of the first filter cartridge 16, and the end of the rotating rod 11 extends into the second filter cartridge 10.
