Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an automatic spraying and foam removal device for a sewage treatment station. Background Art

[0002] When treating sewage, sewage treatment plants usually follow a series of complex steps to ensure effective improvement of water quality. Oxidation treatment is a key step for sewage treatment plants, mainly used to remove organic matter in the water. This treatment process usually involves adding oxidants such as oxygen or ozone to the oxidation tank to promote the oxidation reaction of organic matter in the water and convert it into inorganic matter. This conversion process helps to reduce the pollution level of sewage and improve water quality.

[0003] During the oxidation process, the generation of bubbles is a common phenomenon. These bubbles may come from the added oxidants or the original gases in the sewage. The presence of bubbles may affect the efficiency of the oxidation treatment because they may hinder the oxidants from fully contacting with the organic matter in the sewage, thereby reducing the speed and effect of the oxidation reaction.

[0004] Existing defoaming devices usually use a spray system to eliminate bubbles. During use observation, it was found that microorganisms would multiply rapidly on the inner wall of the spray pipe and cause blockage, which would reduce the water output of the spray system and reduce the device's ability to eliminate bubbles.

[0005] Therefore, in view of the above problems, an automatic spraying and foam removal device for a sewage treatment station is proposed. Utility Model Content

[0030] See also Figure 4 As shown, a plurality of guide plates 5 are fixedly connected to the middle of the sleeve 4; a plurality of fourth circular holes 52 are opened in the middle of the guide plate 5; the guide plate 5 is an arc-shaped structure; after the gas is ejected from the sleeve 4, it will enter the sewage and form bubbles, and the bubbles will pass through the guide plate 5 and flow along the surface of the guide plate 5. Because the surface of the guide plate 5 is an arc-shaped structure, the bubbles will diffuse along the surface of the guide plate 5; by providing the guide plate 5, the bubbles will diffuse when passing through the guide plate 5, thereby increasing the distribution range of the bubbles in the sewage and enhancing the treatment effect of the bubbles on the sewage.

[0031] See also Figure 2 and Figure 5 As shown, the inner side wall of the feed port 102 is fixedly connected with a rotating seat 6; the middle part of the rotating seat 6 is fixedly connected with an auger 62; when the sewage enters the box body 1 from the feed port 102, the sewage will pass through the auger 62, and the auger 62 will be affected by the flow of the sewage and rotate, and the auger 62 will transport the sewage when rotating, reducing the possibility of blockage in the feed port 102.

[0033] Working principle: After the sewage is injected into the interior of the box 1 through the feed port 102, the device is started. After the device is started, the water pump 112 is started, and air is injected into the air inlet pipe 104 at the same time. After passing through the air inlet pipe 104, the gas will enter the interior of the air outlet pipe 105 and spray out from the air outlet 106. After the gas enters the sewage, the sewage will start to be aerated aerobically. After the gas flows in the sewage, it will diffuse and form bubbles. The bubbles will float in the sewage and reach the surface of the sewage. After the water pump 112 is started, the water in the water tank 113 will enter the interior of the spray plate 107 through the pipe, and then the water will flow out from the second circular hole 114 and reach the interior of the water distribution plate 110. Then the water will flow out from the first circular hole 111 and spray the sewage to remove bubbles. When the water flows through the second circular hole 114, it will contact the ball 109 and make the ball 109 slide along the water diversion plate 110 under the action of the water flow. When the ball 109 and the water diversion plate 110 rub against each other, the inner wall of the water diversion plate 110 will be cleaned, and the dirt attached to the inner wall of the water diversion plate 110 will be reduced. The treated sewage can be discharged through the discharge port 103 and proceed to the next step of treatment. When the device stops working, the first baffle plate 22 will block the end of the water diversion plate 110 to reduce the impurities entering the water diversion plate 110. When the device starts, the ball 109 will slide along the water diversion plate 110 and contact the first baffle plate 22. The first baffle plate 22 will rotate under the pressure of the ball 109. The angle of the first baffle plate 22 will change when it rotates. When the water flows out from the first circular hole 111, it will reach the surface of the first baffle plate 22. Part of the water will flow along the surface of the first baffle plate 22 and flow out from the edge of the first baffle plate 22, and part of the water will be directly ejected from the third circular hole 23, thereby increasing the distribution range of the water flow in the device; when the first baffle plate 22 rotates, it will drive the slide bar 3 to rotate together, and when the slide bar 3 rotates, it will also drive the bristles 32 to rotate together. When the slide bar 3 moves, it will enter the interior of the first circular hole 111, and when the bristles 32 move, they will contact the inner wall of the first circular hole 111 and clean the inner wall of the first circular hole 111, thereby reducing impurities attached to the inner wall of the first circular hole 111; when the gas is ejected from the air outlet 106, it will enter the interior of the sleeve 4, and then the airflow will interact with the second baffle plate 42. The second baffle plate 42 contacts and deforms, and then the airflow is ejected from the sleeve 4 and enters the sewage. When the device stops conveying air, the adjacent second baffle plates 42 are pressed against each other to seal the sleeve 4, thereby reducing impurities entering the air outlet pipe 105. After the gas is ejected from the sleeve 4, it enters the sewage and forms bubbles. The bubbles pass through the guide plate 5 and flow along the surface of the guide plate 5. Because the surface of the guide plate 5 is an arc-shaped structure, the bubbles diffuse along the surface of the guide plate 5. When the sewage enters the box body 1 from the feed port 102, the sewage passes through the auger 62. The auger 62 is affected by the flow of the sewage and rotates. When the auger 62 rotates, the sewage is transported, thereby reducing the possibility of blockage in the feed port 102.When the auger 62 rotates, it drives the second connecting rod 7 to rotate together, and when the second connecting rod 7 rotates, it drives the scraper 72 to rotate together. When the scraper 72 rotates, it contacts the inner wall of the feed port 102 and cleans the inner wall of the feed port 102, thereby reducing impurities attached to the inner wall of the feed port 102 and reducing blockage when the feed port 102 transmits sewage.
