Description

Technical Field

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

[0002] Dyeing wastewater is wastewater discharged from printing and dyeing, wool dyeing and finishing, and silk factories that mainly process cotton, linen, chemical fibers and their blended products, and silk. The amount and quality of printing and dyeing wastewater vary depending on the type of fiber and the processing technology. Among them, the amount of wastewater from printing and dyeing factories is relatively large. Each printing and dyeing process of 1 ton of textile consumes 100 to 200 tons of water, of which 80% to 90% is discharged as wastewater. Printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. It is one of the difficult-to-treat industrial wastewaters. The wastewater contains dyes, slurries, additives, oils, acids and alkalis, fiber impurities, sand substances, inorganic salts, etc. Wastewater treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. When treating printing and dyeing wastewater, filtering devices are usually used for filtering.

[0003] When the existing filtering device is used to filter printing and dyeing wastewater, since the printing and dyeing wastewater contains many fiber impurities such as lint, the filter screen of the filtering device needs to be frequently disassembled and cleaned, which is inconvenient to use. Moreover, when the filter screen is cleaned, filtering treatment cannot be performed, which affects the treatment efficiency. For this reason, we propose a filtering device for dyeing and sewage treatment to solve the above problems. Utility Model Content

A support shaft 18 is fixedly provided on the outer side of the tilting barrel 5. A connecting frame 19 is rotatably provided on the outer side of the support shaft 18. The connecting frame 19 is fixed to the upper side of the bottom of the trough 16. Two water baffles 20 are fixedly provided on the upper side of the trough 16. When in use, the water inlet pipe 2 needs to be connected to the printing and dyeing sewage that needs to be filtered and treated. The printing and dyeing sewage will flow into the tilting barrel 5 through the water inlet pipe 2. The printing and dyeing sewage in the tilting barrel 5 will automatically flow out of the tilting barrel 5 through the arc filter 6 and the arc grid frame 7, and then fall into the trough 16. The water in the trough 16 can be discharged through the drainage pipe 17. In this process, the arc filter 6 will filter out impurities such as fluff in the printing and dyeing sewage, so that filtering treatment can be carried out;

[0022] A driving rotating assembly is provided on one side of the tilting barrel 5, and the driving rotating assembly includes a motor 8, which is fixed on the outer periphery of the tilting ring 4, and the motor 8 is connected to an external power supply and a switch through a wire. A driving gear 9 is fixed on the shaft end of the motor 8, and a driven gear 10 is fixed on the outer periphery of the tilting barrel 5. The driven gear 10 is connected to the driving gear 9 through meshing transmission. An arc-shaped oblique brush 13 is fixed on one side of the fixing plate 11, and the arc-shaped oblique brush 13 contacts the inner wall of the tilting barrel 5, and the arc-shaped oblique brush 13 contacts the arc-shaped filter 6.

During this period, it is necessary to turn on the motor 8. When the motor 8 is turned on, it will drive the driving gear 9 to rotate. When the driving gear 9 rotates, it will drive the driven gear 10 and the tilting barrel 5 to rotate together. At this time, the tilting barrel 5 and the arc filter 6 will rotate. When the tilting barrel 5 rotates, the arc-shaped oblique brush 13 will brush off the impurities filtered out of the arc filter 6, thereby realizing automatic cleaning. After the impurities on the arc filter 6 are brushed off, water can also quickly pass through the arc filter 6, thereby improving the filtration efficiency. The impurities on the arc-shaped oblique brush 13 will slowly move to the barrel mouth of the tilting barrel 5 when the tilting barrel 5 keeps rotating, and finally fall into the debris bucket 14 and the collection box 15, so that manual cleaning is not required, which is convenient for use.
