Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device with a self-cleaning function. Background Art

[0002] Sewage discharge is mostly divided into two categories: industrial wastewater and domestic wastewater. Industrial wastewater often contains heavy metals and chemicals, and needs to be treated by supporting sewage treatment equipment to meet the standards before it can be discharged. Domestic wastewater contains a large amount of floating matter and is more complex in impurities.

[0003] For example, Publication No. CN203333400U, titled "A Sewage Treatment Device," includes a water inlet, a first valve, a sewage tank, a filter, a water outlet, a second valve, and an activated carbon layer. This utility model's sewage treatment device effectively addresses the treatment of medium- and small-scale industrial wastewater, ensuring that treated industrial wastewater meets discharge requirements while reducing capital investment for small and medium-sized enterprises. Furthermore, the utility model is simple to operate and low-cost.

[0004] The above device does not have a self-cleaning function during use. A large amount of unfiltered sewage will adhere to the inner wall of the sewage filter box, which is not convenient for subsequent cleaning. Using a fixed filter plate to filter out impurities in the sewage can easily cause the filter plate to be blocked, affecting the treatment effect and rate. Therefore, we propose a sewage treatment device with a self-cleaning function to solve the above problems. Utility Model Content

[0022] See also Figure 1 A liquid inlet 3 is installed on the other side of the top of the filter tank 1. During the sewage treatment process, chemicals can be added through the liquid inlet 3, which improves the sewage treatment efficiency and can effectively remove impurities and pollutants in the water so that the water quality meets the discharge standards. After the sewage treatment is completed, the cleaning liquid can be injected through the liquid inlet 3 to clean the device, thereby improving the practicality of the device.

[0023] See also Figure 4 The first rotating shaft 11 and the second rotating shaft 13 are connected by a coupling 12. The coupling 12 can ensure that the first rotating shaft 11 and the second rotating shaft 13 rotate at the same time, thereby improving the stability of the device.

[0024] See also Figure 3 and Figure 4A reinforcement rod 21 is installed between the second vertical rod 17 and the third vertical rod 19.

[0025] See also Figure 3 and Figure 4 The bottom of the second vertical rod 17 and the third vertical rod 19 are connected by a scraper 22. The scraper 22 can scrape and clean the sewage impurities adhering to the bottom of the filter tank 1, thereby improving the self-cleaning effect of the device.

[0026] See also Figure 2 A valve 25 is installed at one end of the first slag discharge port 23 and the second slag discharge port 24. The valve 25 can control the opening and closing of the first slag discharge port 23 and the second slag discharge port 24 to prevent sewage from flowing out of the first slag discharge port 23 and the second slag discharge port 24, thereby affecting the sewage treatment quality of the device.

[0027] See also Figure 4 The first slag discharge port 23 is communicated with the first filter area 6, the second slag discharge port 24 is communicated with the second filter area 7, and the water outlet 26 is communicated with the water collection chamber 8. Impurities can be collected through the first slag discharge port 23 and the second slag discharge port 24, thereby avoiding manual impurity removal.

[0028] Working principle: When in use, sewage enters the first filter area 6 from the water inlet 2, and is filtered for the first time through the filter plate 4. The filtered sewage enters the second filter area 7, and is filtered for the second time through the filter mesh cylinder 5 so that the sewage meets the discharge standard. The treated sewage flows into the water collection chamber 8 and is discharged from the water outlet 26. The drive motor 9 is started, and the first rotating shaft 11 is driven to rotate through the rotating shaft 10, thereby driving the cleaning brush 20 on the first horizontal bar 14 and the first vertical bar 15 to rotate to clean the inner wall of the filter tank 1 and the filter plate 4. The cleaned impurities are discharged from the first slag discharge port 23. The first rotating shaft 11 drives the second rotating shaft 13 to rotate through the coupling 12, and drives the cleaning brush 20 on the side of the second vertical bar 17 to rotate through the second horizontal bar 16 to clean the inner wall of the filter tank 1. The cleaning brush 20 on the side of the third vertical bar 19 is driven to rotate through the third horizontal bar 18 to clean the filter mesh cylinder 5, and the cleaned impurities are discharged from the second slag discharge port 24.
