Description

Technical Field

[0002] In some suburban areas or rural areas, the concentration of residents is not as high as in cities, and the settlements are relatively scattered. In many cases, the treatment methods for domestic sewage generated by residents are relatively simple and direct, and even kitchen wastewater and toilet sewage are directly discharged into the surface or rivers, causing a certain degree of soil pollution or water pollution. As people's living conditions continue to improve, people's requirements for living environment are getting higher and higher, and the treatment methods of kitchen sewage, toilet sewage, etc. have also received attention.

[0003] The existing aeration device for rural sewage treatment needs to filter the sewage before aeration to remove the dirt in the wastewater. After filtration, aeration is performed. First, the wastewater passes through the filter, and then the particles in the wastewater are intercepted on the surface of the filter. However, the filter will be blocked during long-term use. People cannot find the blockage of the filter in time, resulting in reduced wastewater treatment efficiency. In addition, the intercepted objects on the filter need to be cleaned manually, which is time-consuming and labor-intensive. At the same time, the work of cleaning the intercepted objects on the filter will interrupt the wastewater treatment process, resulting in lower wastewater treatment efficiency. Therefore, it is urgent to design a photovoltaic-driven aeration device for rural sewage treatment. Summary of the invention

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] First, by shielding the protective shell, it is not only convenient for people to replace the conical filter element, but also convenient for people to clean the intercepted objects. The cleaning process will not interrupt the wastewater treatment process, which helps to increase the wastewater treatment efficiency. The filter component can filter the wastewater to purify the wastewater. The conical filter element is set in a conical shape, so that the wastewater can flush the intercepted objects on the surface of the conical filter element, exert an oblique downward thrust on the intercepted objects, and then make the intercepted objects slide downward along the surface of the conical filter element to avoid the conical filter element from being blocked, which helps to further increase the wastewater treatment efficiency. The anti-blocking reinforcer allows people to discover the status of the filter element in time. At the same time, the anti-blocking reinforcer can drive the filter element to move, so that the intercepted objects on the surface of the conical filter element obtain centrifugal force, and use the centrifugal force to make the intercepted objects fall off the surface of the conical filter element, again avoiding the conical filter element from being blocked, which helps to once again increase the wastewater treatment efficiency and improve the practicality of the photovoltaic-driven aeration device for rural sewage treatment.

[0019] Secondly, the anti-blocking reinforcer can drive the radial pusher to rotate, so that the running direction of the radial pusher is opposite to the running direction of the filter assembly. Through the operation of the radial pusher, centrifugal force is applied to the detached intercepted objects, so that the intercepted objects adhere to the inner wall of the centrifugal pusher barrel and promote the intercepted objects to stay away from the conical filter element, thereby avoiding the conical filter element from being blocked, which helps to increase the wastewater treatment efficiency. The conical filter element is synchronized with the automatic cleaner to make the running direction of the automatic cleaner opposite to that of the radial pusher. The automatic cleaner can exert an upward push force on the intercepted objects on the inner wall of the centrifugal pusher barrel. The delivery force is used to clean out the intercepted objects inside the centrifugal pusher barrel. There is no need to manually interrupt the wastewater treatment process to clean out the intercepted objects inside the centrifugal pusher barrel, which helps to further increase the wastewater treatment efficiency. The hydraulic drive can drive the rotary scraper to rotate, and the rotary scraper can scrape off the intercepted objects adhering to the inner wall of the tapered cone shell. The pressure compensator can make the rotary scraper fit more closely with the inner wall of the tapered cone shell, ensuring that the rotary scraper can more fully clean the inner wall of the tapered cone shell, thereby improving the practicability of the photovoltaic driven aeration device for rural sewage treatment.

[0020] Thirdly, solar energy is converted into electrical energy through solar panels and stored in batteries. The batteries power the aeration pumps through the aeration controller, thereby saving energy while achieving the mobility of the device, which is very suitable for the dispersed living conditions in rural areas and improves the practicality of the photovoltaic-driven aeration device for rural sewage treatment.

[0043] Working principle:

[0044] First, wastewater enters the hydraulic drive disc box 61 at a constant flow rate through the wastewater injection pipe 112, and then the wastewater impacts the stressed water wheel blades 63, and then the stressed water wheel blades 63 rotate with the transmission expansion tube 62 under the action of the impact force, and then the transmission expansion tube 62 rotates with the rotating scraper block 71, and then the rotating scraper block 71 rotates with the pressure-applying shifting rod 75, and then the pressure-applying shifting rod 75 rotates with the rotating scraper bar 76, and then the stress storage piston 74 applies a thrust to the top of the rotating scraper bar 76 through the pressure-applying shifting rod 75 under the action of the elastic force of the stress storage spring 73, so that the top of the rotating scraper bar 76 is pressed on the inner wall of the tapered cone shell 110, and then the pressure compensation disc 84 applies a thrust to the rotating scraper bar 76 through the pressure compensation rod 85 under the action of the elastic force of the pressure compensation spring 83 The bottom end of the rotating scraping strip 76 applies a thrust so that the bottom end of the rotating scraping strip 76 is pressed against the inner wall of the tapered cone shell 110, so that the rotating scraping strip 76 fits against the inner wall of the tapered cone shell 110, and then the rotating scraping strip 76 slides on the inner wall of the tapered cone shell 110 to scrape off the intercepted objects adhering to the inner wall of the tapered cone shell 110, and then the scraped intercepted objects fall downward and pass through the bearing base ring 106 and fall into the inside of the collection opening box 102, and then the wastewater falls on the surface of the conical filter element 23 through the transmission expansion pipe 62 and the wastewater drop pipe 24, and then the wastewater passes through the through hole on the conical filter element 23 and enters its interior, and then the wastewater passes through the through hole on the bottom surface of the conical filter element 23 and passes through the straightening plug pipe 45 to enter the transfer water Inside the barrel 47, the liquid level inside the transfer water storage barrel 47 gradually rises, and the water entering the transfer water storage barrel 47 is aerated by the aeration pump 12. The aeration pump 12 is connected to the microporous aeration disk through the aeration pipe. The microporous aeration disk is arranged at the bottom of the transfer water storage barrel 47. A control cabin is arranged at the bottom of the transfer water storage barrel 47. The aeration pump 12 and the aeration controller 11 are located in the control cabin. A conductive ring is arranged on the outer surface of the control cabin. The aeration controller 11 is connected to the battery 10 through the conductive ring; then the wastewater is discharged to the next treatment link through the water drop hole 48, the rotating vertical pipe 311, the rotating joint 310, and the drainage pipe 107. In this process, the particulate matter in the wastewater is intercepted on the surface of the conical filter element 23 to form an interception object, and then the wastewater falls to the bottom of the pipe 24. The wastewater subsequently ejected from the end exerts a downward impact force on the intercepted objects on the surface of the conical filter element 23, and then the intercepted objects slide downward along the surface of the conical filter element 23 under the action of the impact force to prevent the conical filter element 23 from being blocked, and then the intercepted objects move to the bottom surface of the inner cavity of the centrifugal push-off barrel 43, and then the electronic liquid level meter 315 detects the liquid level inside the transfer water storage barrel 47 in real time and sends the detected data to the power distribution intelligent control box 105, and the power distribution intelligent control box 105 is provided with a minimum liquid level value, and then the power distribution intelligent control box 105 compares the received data with the minimum liquid level value. When the data received by the power distribution intelligent control box 105 is greater than the minimum liquid level value, it indicates that the conical filter element 23 has good permeability. When the data received by the power distribution intelligent control box 105 is less than the minimum liquid level value,This indicates that the permeability of the conical filter element 23 is reduced, and the intercepted objects inside the centrifugal push-off barrel 43 need to be cleaned. Then the power distribution intelligent control box 105 controls the anti-blocking drive motor 305 to run, and then the anti-blocking drive motor 305 drives the driving bevel gear 306 to rotate. Then the driving bevel gear 306 drives the linkage cross bar 307 to rotate through the meshing action between it and the transmission bevel gear 308, and then the linkage cross bar 307 drives the transfer bevel gear 309 to rotate, and then the transfer bevel gear 309 drives the rotating vertical pipe through the meshing action between it and the synchronous bevel gear 312. 311 rotates, and then the rotating vertical pipe 311 rotates forward with the conical filter element 23 through the plugging effect between the angular docking column 313 and the inner angular pipe 314, and then the intercepted objects on the surface of the conical filter element 23 and in its pores are thrown off under the action of centrifugal force, so as to achieve the effect of plugging, and then the transfer bevel gear 309 rotates with the transfer water bucket 47 through the meshing effect between it and the asynchronous bevel gear 49, and then the transfer water bucket 47 rotates in the opposite direction with the centrifugal push-off bucket 43, and then the intercepted objects inside the centrifugal push-off bucket 43 are attached to the centrifugal push-off bucket 43 under the action of centrifugal force. On its inner wall, the conical filter element 23 then rotates forward with the spiral rotary scraper 53 by installing the track bar 51 and the centering diagonal support bar 52, and then the spiral rotary scraper 53 rotates relative to the centrifugal push-off barrel 43, and then the spiral rotary scraper 53 applies an upward thrust to the intercepted objects inside the centrifugal push-off barrel 43, and then the intercepted objects slide upward along the inner wall of the centrifugal push-off barrel 43, and then the intercepted objects emerge from the top of the centrifugal push-off barrel 43, and then the intercepted objects slide to the top surface of the centrifugal fly-off circle 44 under the action of centrifugal force and fly out from its edge, and then the intercepted objects hit On the inner wall of the tapered cone housing 110, some intercepted objects remain on the inner wall of the tapered cone housing 110, and most of the intercepted objects fall into the inside of the collection opening box 102 under the action of gravity. Then, the power distribution intelligent control box 105 counts the running time of the anti-blocking drive motor 305. When the running time of the anti-blocking drive motor 305 reaches the preset value inside the power distribution intelligent control box 105, the power distribution intelligent control box 105 turns off the anti-blocking drive motor 305, then takes out the collection opening box 102 and pours out the intercepted objects inside it, and then puts it back to its original position.
