Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a sludge scraping device for environmentally friendly wastewater treatment. Background Technology

[0002] Wastewater treatment is a process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. However, when wastewater is poured into the tank, the presence of relatively large particles in the wastewater can affect the mixing of wastewater and chemicals, and is not conducive to the subsequent discharge of the mixture. Furthermore, direct discharge of the mixture of chemicals and wastewater results in the presence of trace impurities in the wastewater, which in turn affects the wastewater purification process and thus impacts environmental protection efforts.

[0003] Sludge in wastewater is a challenge in the treatment process. Wastewater treatment ponds are needed to clean the sludge in the wastewater. After the sludge settles, the sludge inside the wastewater treatment pond needs to be cleaned. However, existing equipment cannot clean the adsorbents on the inner wall of the wastewater treatment pond, resulting in insufficient cleaning. Furthermore, current sludge scraping methods often rely on manual labor or simple mechanical tools, which are inefficient, labor-intensive, and difficult to guarantee the thoroughness of sludge scraping.

[0004] Based on this, a sludge scraping device for wastewater environmental treatment is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

A first sludge scraping mechanism is provided on the inner wall of the wastewater treatment tank 1, and a second sludge scraping mechanism is provided on the guide bottom 2. A cleaning mechanism is provided inside the wastewater treatment tank 1 at the bottom of the mounting plates 7. The first sludge scraping mechanism can clean the adsorbed dirt on the inner wall of the wastewater treatment tank 1, and the second cleaning mechanism can clean the dirt on the guide bottom 2 at the bottom of the wastewater treatment tank 1. This avoids the need for manual scraping of sludge using simple mechanical tools, greatly improving work efficiency. The cleaning mechanism can spray water on the sludge to dilute it and make it easier to scrape off, improving practicality.

[0021] In one embodiment, such as Figure 3 As shown, a support plate 17 is provided inside the drain outlet 3. The support plate 17 is fixedly connected to the inner wall of the drain outlet 3 by several support rods 18. A motor 9 is provided on the fixed plate 6. A rotating shaft 10 is provided at the output end of the motor 9. The bottom end of the rotating shaft 10 is rotatably connected to the support plate 17. The motor 9 can drive the rotating shaft 10 to rotate.

[0022] In one embodiment, such as Figure 3 As shown, the first sludge scraping mechanism includes a first connecting rod 11. One end of the first connecting rod 11 is fixedly connected to the rotating shaft 10, and the other end of the first connecting rod 11 is provided with a first connecting plate 12. A first scraper 13 is provided on the outer side of the first connecting plate 12 and contacts the side wall of the sewage treatment tank 1. During the rotation of the rotating shaft 10, the first connecting rod 11 is driven to rotate synchronously, thereby driving the first connecting plate 12 to rotate. The first scraper 13 on the first connecting plate 12 cleans the adsorbed dirt on the inner wall of the sewage treatment tank 1.

[0023] In one embodiment, such as Figure 3 As shown, the second sludge scraping mechanism includes a second connecting rod 14. One end of the second connecting rod 14 is fixedly connected to the rotating shaft 10, and a second connecting plate 15 is provided on the other side of the second connecting rod 14. A second scraper 16 is provided on the outer side of the second connecting plate 15 and contacts the inner surface of the guide bottom 2. When the rotating shaft 10 rotates, it drives the second connecting rod 14 to rotate synchronously, thereby driving the second connecting plate 15 to rotate. The second scraper 16 on the second connecting plate 15 cleans the dirt on the guide bottom 2 at the bottom of the sewage treatment tank 1.

[0024] In one embodiment, such as Figure 3 and Figure 4 As shown, the cleaning mechanism includes an annular water spray pipe 19, which is fixedly connected to the bottom of the mounting plate 7 via an annular buckle 20. Several nozzles 21 are provided on the outside of the annular water spray pipe 19.

[0027] Working principle: When the inner wall and bottom of the sewage treatment tank 1 contain a large amount of sludge, the water pump 23 is started to inject water into the annular spray pipe 19. The annular spray pipe 19 can spray water to dilute the sludge in the sewage treatment tank 1, making it cleaner to scrape off. The motor 9 is started to drive the rotating shaft 10 to rotate. During the rotation of the rotating shaft 10, the first connecting rod 11 rotates synchronously, thereby driving the first connecting plate 12 to rotate. The first scraper 13 on the first connecting plate 12 cleans the adsorbed dirt on the inner wall of the sewage treatment tank 1. At the same time, the rotating shaft 10 drives the second connecting rod 14 to rotate synchronously, thereby driving the second connecting plate 15 to rotate. The second scraper 16 on the second connecting plate 15 cleans the dirt on the bottom guide bottom 2 of the sewage treatment tank 1. This avoids the need for manual scraping of sludge using simple mechanical tools, greatly improving work efficiency.
