DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1-3 A novel energy-saving deep well aeration device shown includes a cylinder body 2 and an air pump 11 installed inside the cylinder body 2;

[0028] An exhaust pipe 12 is fixedly connected to the inner part of the outer wall of the lower end of the air pump 11 to guide the flow direction of the gas;

[0029] The lower end outer wall of the exhaust pipe 12 is fixedly connected with an aeration head 14 to spray the gas in the form of dispersed bubbles;

[0030] The filter screen 3 is fixedly connected to the outer wall of the lower end of the cylinder body 2, and the base 6 is fixedly connected to the outer wall of the lower end of the filter screen 3. When the sewage pool is aerated, the outside air is sucked by the air pump 11 and discharged from the exhaust pipe 12 after being pressurized. After the gas moves in the exhaust pipe 12, it will be discharged from the aeration head 14 and diffused outward through the filter screen 3 to perform aeration operation inside the sewage pool;

[0031] The outer walls of the left and right ends of the exhaust pipe 12 are fixedly connected with diverter pipes 20 near the lower side to divert the flow direction of the gas. The other ends of the two diverter pipes 20 are fixedly connected with guide pipes 21. The inner walls of the left and right ends of the filter 3 are provided with scrapers 15 to scrape off the sludge attached to the inner wall of the filter 3 under the drive of the gas ejected from the guide pipe 21. In the process of gas transportation and movement of the exhaust pipe 12, the gas will be diverted through the diverter pipe 20 and discharged from the guide pipe 21. The gas discharged from the guide pipe 21 will push the scraper 15 abutting the inner wall of the filter 3 to rotate, thereby scraping off the sludge attached to the mesh of the filter 3 and on the inner wall of the filter 3, and pushing it out along with the bubbles discharged from the aeration head 14, thereby avoiding the blockage of the mesh of the filter 3.

[0032] like Figure 3 and Figure 4 As shown, a filter plate 17 is fixedly connected between the lower outer walls of the two scrapers 15 to guide the sludge inside the filter screen 3 to move downward, a mud discharge port 16 is opened inside the base 6 to discharge the sludge guided by the filter plate 17 to the outside, a positioning rod 18 is fixedly connected to the center of the lower inner wall of the mud discharge port 16, and a support plate 19 is fixedly connected between the left and right outer walls of the positioning rod 18 to lift the filter plate 17.

[0033] When the sludge in the sewage pool enters the filter 3, it will move downward through the filter plate 17 and guide the sludge outward from the sludge discharge port 16 to prevent the sludge from accumulating inside the filter 3. When the scraper 15 drives the filter plate 17 to rotate, the rotation center and position of the filter plate 17 are limited by the positioning rod 18, and the height of the filter plate is limited by the support plate 19.

[0034] like Figure 5 As shown, the guide pipe 21 is inclined, and the outer wall of the lower end of the guide pipe 21 is higher than the outer wall of the upper end of the scraper 15.

[0035] The inclined guide tube 21 can provide the gas with an accurate moving direction, thereby pushing the scraper 15 to rotate clockwise. The lowermost outer wall of the guide tube 21 is higher than the upper outer wall of the scraper 15 to prevent the scraper 15 from hitting the guide tube 21 when rotating.

[0036] like Figure 3 As shown, when the two scrapers 15 are driven to rotate by the gas blown out of the guide pipe 21, they will synchronously drive the filter plate 17 to rotate, and the two scrapers 15 and the filter plate 17 are fixedly connected by welding.

[0037] When the scraper 15 rotates, it drives the filter plate 17 to rotate simultaneously, so as to avoid the filter plate 17 from being blocked and increase the discharge speed of the sludge accumulated inside the filter screen 3.

[0038] like Figure 1 and Figure 2As shown, the upper outer wall of the cylinder body 2 is fixedly connected with a fixed end 1, the upper outer wall of the vacuum pump 11 is fixedly connected with a vacuum fan blade 9 to inhale air and guide it to the exhaust pipe 12, a fixture 10 is fixedly connected between the left and right outer walls of the vacuum pump 11 to limit the position of the vacuum pump 11 inside the cylinder body 2, an air inlet 8 is opened inside the upper outer wall of the fixture 10, a cable 7 is fixedly connected to the leftmost side of the upper outer wall of the fixture 10 to provide power to the vacuum pump 11, and the other end of the cable 7 is electrically connected to an external power supply, a waterproof plate 13 is fixedly connected between the left and right inner walls of the cylinder body 2 near the lower side, and the left and right outer walls of the base 6 are fixedly connected with fixed feet 5, and the upper outer walls of the two fixed feet 5 are provided with fixing bolts 4 to be fixedly connected to the bottom of the sewage pool.

[0039] When the vacuum pump 11 is working, it is powered by the cable 7, driving the vacuum fan blades 9 to rotate, inputting gas from the air inlet 8 and discharging it from the exhaust pipe 12. During the operation, the waterproof plate 13 can prevent the liquid in the sewage pool from contacting the vacuum pump 11. When the cylinder body 2 is installed and fixed, the fixing foot 5 is placed close to the bottom of the sewage pool and fixedly connected to the bottom of the sewage pool through the fixing bolts 4.

[0040] The implementation principle of this embodiment is as follows: when the sewage pool is aerated, the outside air is sucked in by the vacuum pump 11 and pressurized before being discharged from the exhaust pipe 12. When the vacuum pump 11 is working, it is powered by the cable 7 to drive the vacuum fan blades 9 to rotate, and the gas is input from the air inlet 8 and discharged from the exhaust pipe 12. After the gas moves in the exhaust pipe 12, it will be discharged from the aeration head 14 and diffuse outward through the filter 3 to perform aeration operation inside the sewage pool. In the process of the exhaust pipe 12 conveying and moving the gas, the gas will be diverted through the diverter pipe 20 and discharged from the guide pipe 21. The gas discharged from the guide pipe 21 will push the scraper 15 abutting the inner wall of the filter 3 to rotate, thereby scraping off the sludge attached to the mesh of the filter 3 and the inner wall of the filter 3, and pushing it out along with the bubbles discharged from the aeration head 14, thereby avoiding the blockage of the mesh of the filter 3.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
