Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, and specifically relates to a sewage purification device for sewage treatment. Background Technique

[0002] Sewage treatment is a process of removing pollutants from sewage to meet the discharge standards or enable reuse. Sewage treatment is of great significance for protecting the environment, public health, and the sustainable use of water resources. Sewage purification devices are the main equipment for sewage treatment;

[0003] In the prior art, a patent with the publication number of CN218539470U discloses a sewage purification device for sewage treatment. When treating sewage, sewage can enter the treatment pool through the water inlet pipe. Larger impurities such as metal waste can be intercepted by the grille, and strip-shaped impurities such as plastic bags can be intercepted by the thorns on the upper end of the filter rack. Subsequently, the sewage enters the filter assembly through the through holes, so that the filter assembly can filter out fine impurities in the sewage, thus avoiding the influence of impurities such as plastic bags and metal waste on the sewage treatment effect. Then, the sewage can enter the treatment pool, and the sewage is pumped into the reaction pool by a water pump, and then the sewage can be purified by the MBR membrane assembly, and the purified sewage is sent into the clear water pool. Subsequently, the purified sewage is discharged through the drain pipe;

[0004] However, in the above technology, when the filter assembly filters fine impurities, the fine impurities will accumulate on the filter screen, resulting in a gradual decrease in the permeability of the filter screen, reducing the efficiency of sewage passing through the filter screen, and further reducing the efficiency of sewage purification.

[0020] 1. By arranging an inclined filter plate inside the filter box, when the sewage passes through the filter screen, the fine impurities in the sewage are filtered by the filter screen. And because the filter screen is obliquely arranged, the fine impurities filtered by the filter screen stay on the downward side of the filter screen. Under the action of gravity, the fine impurities staying on the surface of the filter screen will fall into the inside of the collecting hopper, thus avoiding the problem that the passing performance of the filter screen decreases due to excessive accumulation of impurities on the surface of the filter screen.

[0021] 2. By setting the fan blades and the rotary brush, when water flows through the filter screen, the fan blades drive the sleeve to rotate on the surface of the first mounting shaft under the impact of the water flow.

[0037] For a sewage purification device for sewage treatment proposed by the present utility model, when sewage treatment is carried out, the rear water inlet pipe 3 is connected to the treatment tank, and then sewage is introduced into the interior of the filter box 2 through the front water inlet pipe 1. When the sewage passes through the interior of the front water inlet pipe 1, the filter grille arranged inside the front water inlet pipe 1 filters large impurities such as plastic bags and metal waste in the sewage. After the sewage successively passes through the bottom of the first baffle 11 and the top of the second baffle 23, it flows towards the filter screen 41. When the sewage passes through the filter screen 41, the fine impurities in the sewage are filtered by the filter screen 41. And because the filter screen 41 is obliquely arranged, the fine impurities filtered by the filter screen 41 stay on the downward side of the filter screen 41. Under the action of gravity, the fine impurities staying on the surface of the filter screen 41 will fall into the interior of the collection hopper 21, thus avoiding the problem that the impurity accumulation on the surface of the filter screen 41 is excessive and the permeability of the filter screen 41 decreases;

[0038] Meanwhile, by arranging the first baffle 11 and the second baffle 23, the backflow of sewage inside the filter box 2 is avoided, so that the impurities falling into the interior of the collection hopper 21 are not washed out by the water flow. Embodiment

[0039] On the basis of Embodiment 1, by arranging the fan blade 51 and the rotary brush 53, when the water flow passes through the filter screen 41, under the impact of the water flow, the fan blade 51 drives the shaft sleeve 5 to rotate on the surface of the first mounting shaft 25. At this time, the shaft sleeve 5 drives the rotary brush 53 to rotate through the second mounting shaft 52, so that the rotary brush 53 rolls on the surface of the filter screen 41 to loosen the impurities adhered to the surface of the filter screen 41, further ensuring the permeability of the filter screen 41.

[0040] Working principle: Sewage treatment is a process to remove pollutants in sewage so that it meets the discharge standards or can be reused. A sewage purification device for sewage treatment proposed by the present utility model, when treating sewage, connects the rear water inlet pipe 3 to the treatment tank, and then passes the sewage into the interior of the filtration box 2 through the front water inlet pipe 1. When the sewage passes through the interior of the front water inlet pipe 1, the filter grille provided inside the front water inlet pipe 1 filters large impurities such as plastic bags and metal waste carried in the sewage. After the sewage successively passes through the bottom of the first baffle 11 and the top of the second baffle 23, it flows towards the filter screen 41. When the sewage passes through the filter screen 41, the fine impurities in the sewage are filtered by the filter screen 41. And because the filter screen 41 is inclined, the fine impurities filtered by the filter screen 41 stay on the downward side of the filter screen 41. Under the action of gravity, the fine impurities staying on the surface of the filter screen 41 will fall into the interior of the collection hopper 21. When the water flow passes through the filter screen 41, under the impact of the water flow, the fan blade 51 drives the bushing 5 to rotate on the surface of the first mounting shaft 25. At this time, the bushing 5 drives the rotary brush 53 to rotate through the second mounting shaft 52, so that the rotary brush 53 rolls on the surface of the filter screen 41 to loosen the impurities adhered to the surface of the filter screen 41.
