Description

Technical Field

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

[0002] As we all know, sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. With the improvement of living standards, the acceleration of pace, and the need for development, the discharge of sewage has increased year by year, and how to treat sewage has become the main problem to be solved.

[0003] In the process of sewage treatment, any kind of sewage will contain more or less sand and mud, which are usually filtered first. Now a horizontal filtering device is used, in which a filter cartridge is driven by a motor, a mud outlet trough is arranged inside, a water pump and a water spray pipe are arranged outside, and a plurality of nozzles are installed on the water spray pipe. Clean water is sprayed to the filter cartridge through the nozzle to wash away the mud and sand from the filter cartridge to prevent clogging of the filter cartridge. However, the use of the device not only wastes water resources, but also carries a large amount of water when the mud and sand slide out of the mud outlet trough, resulting in the need for filtration.

[0004] For this purpose, we designed a filtering device for a sewage treatment plant. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , a filtering device of a sewage processor of the present invention, including a water tank 1. Openings are provided at the top and one side of the water tank 1. A support frame 2 is installed on the other side of the water tank 1. The support frame 2 includes a connecting plate, and two support rods are fixedly connected to the top of the connecting plate. A fixing ring 4 is fixedly connected to the inner wall of the water tank 1. An outer wall of one end of the fixing ring 4 is fixedly connected to an orbital ring 7. A rotating groove is provided on the inner wall of one end of the filtering cylinder 6, and the rotating groove is matched with the orbital ring 7. A support plate 3 is installed inside the water tank 1. A motor 5 is installed on the top of the support plate 3. A filtering cylinder 6 is installed on the motor 5. A blower 8 is installed on the top of the support plate 3. An air inlet pipe 9 is installed on the blower 8. An air outlet pipe 10 is installed on the blower 8. A plurality of nozzles 11 are installed on the air outlet pipe 10 and are disposed on the top of the filtering cylinder 6. A sewage pipe 12 is installed at one end of the water tank 1. A plurality of sewage holes 15 are provided at the bottom of the sewage pipe 12, and the sewage holes 15 are disposed inside the filtering cylinder 6. A sludge discharge tank 13 is installed on the top of the support frame 2. The sludge discharge tank 13 is L-shaped and one end is inclined downward. A scraper 14 is fixedly connected to the sludge discharge tank 13, and the scraper 14 is in contact with the inner wall of the filtering cylinder 6.
