Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device capable of intelligent control. Background Art

[0002] Sewage treatment has always been an important part of environmental protection projects. Through sewage treatment, the sewage can reach the discharge standard, thereby preventing negative impacts on the environment. During the sewage treatment process, it is usually necessary to filter the sewage.

[0003] There is a sewage treatment device currently (its authorization announcement number is: CN216653737U). It respectively conducts primary filtration, secondary filtration, and tertiary filtration on sewage by arranging a rotating sieve barrel, a filter screen, and a filter layer inside the barrel. An external toothed ring is arranged on the upper part of the rotating sieve barrel and meshes with the driving gear, enabling the rotating sieve barrel to filter sewage during rotation. Since there is centrifugal force during the filtration process, it can effectively accelerate the filtration process. A brush roller is arranged at the bottom of the rotating sieve barrel, enabling the rotating sieve barrel to clean the mesh holes of the filter screen during rotation to prevent blockage and affect filtration.

[0004] However, there are some deficiencies in the actual use of this sewage treatment device: Since there may be some sundries in domestic sewage, during the long-term filtration of domestic sewage by the rotating sieve barrel, some sundries will be filtered and retained in the rotating sieve barrel. Over time, these sundries will block the rotating sieve barrel, affecting the filtration efficiency of the rotating sieve barrel for domestic sewage. Therefore, it is necessary for staff to regularly handle the sundries filtered and retained in the rotating sieve barrel. This method requires manual intervention and has a low degree of automation. Therefore, we have proposed a sewage treatment device capable of intelligent control to solve the above problems. Content of the Utility Model

The driven gear meshes with the external gear ring. A first motor is fixedly installed on the outer wall of one side of the sewage treatment filter tank. The output shaft of the first motor is fixedly installed with a driving gear. The driving gear meshes with the driven gear. By starting the first motor, the driving gear, the driven gear, the external gear ring and the sewage inlet ring are driven to rotate, and then the rotating sieve barrel is driven to rotate in the filter chamber of the sewage treatment filter tank. The rotating sieve barrel filters domestic sewage during the rotation process. Since there is centrifugal force during the filtering process, the filtering process can be effectively accelerated. A brush plate is arranged at the bottom of the rotating sieve barrel, and the mesh holes of the filter screen are cleaned through the brush plate to prevent the mesh holes of the filter screen from being blocked and affecting the filtering of sewage.

[0009] Preferably, one side outer wall of the discharge pipe is attached to the inner wall of the rotating sieve barrel. The cross section of the discharge pipe is arranged in an L-shaped structure. The discharge end of the discharge pipe is arranged to incline downward. An inlet is opened at the bottom end of the discharge pipe. When the rotating sieve barrel rotates, it is convenient for the sundries in the rotating sieve barrel to enter the discharge pipe through the inlet.

[0010] Preferably, the elastic connection mechanism includes a movable circular plate and a spring. A movable circular plate is movably installed in the cylinder chamber.

By starting the second motor, the driving rod drives the spiral conveyor blade to rotate inside the discharge pipe. Through the spiral conveyor blade, the sundries accumulated at the bottom inside the rotating sieve barrel are conveyed upward inside the discharge pipe through the feed inlet until the sundries accumulated at the bottom inside the rotating sieve barrel are discharged to the outside from the discharge end of the discharge pipe.

The contact pressure sensor detects that a blockage signal has occurred inside the rotating sieve barrel at this time and transmits it to the controller. The controller starts the second motor, causing the driving rod to drive the spiral conveyor blade to rotate inside the discharge pipe. Through the spiral conveyor blade, the sundries accumulated at the bottom inside the rotating sieve barrel are conveyed upward inside the discharge pipe through the feed inlet until the sundries accumulated at the bottom inside the rotating sieve barrel are discharged to the outside from the discharge end of the discharge pipe. Thus, it can intelligently and automatically clean the filtered and accumulated sundries inside the rotating sieve barrel without manual intervention, with a high degree of intelligent automation, and at the same time, it also improves the working efficiency of the sewage treatment filter tank for treating domestic sewage.

[0024] Furthermore, the rotation drive mechanism includes a driven gear 6, a first motor 7, and a drive gear 8.

A first motor 7 is fixedly installed on the outer wall of one side of the sewage treatment filter tank 1. The output shaft of the first motor 7 is fixedly installed with a drive gear 8. The drive gear 8 meshes with the driven gear 6. By starting the first motor 7, the drive gear 8, the driven gear 6, the external tooth ring 5, and the sewage inlet ring 3 are driven to rotate, thereby driving the rotating sieve barrel 4 to rotate in the filter chamber 2 of the sewage treatment filter tank 1. The rotating sieve barrel 4 filters domestic sewage during rotation. Since there is centrifugal force during the filtering process, the filtering process can be effectively accelerated. A brush plate is provided at the bottom of the rotating sieve barrel 4 to clean the mesh holes of the filter screen through the brush plate, preventing the mesh holes of the filter screen from being blocked and affecting the filtering of sewage.

[0025] Furthermore, one side outer wall of the discharge pipe 18 is attached to the inner wall of the rotating sieve barrel 4. The cross-section of the discharge pipe 18 is arranged in an L-shaped structure. The discharge end of the discharge pipe 18 is arranged obliquely downward. The bottom end of the discharge pipe 18 is provided with a feed inlet 19. When the rotating sieve barrel 4 rotates, it is convenient for the sundries in the rotating sieve barrel 4 to enter the discharge pipe 18 through the feed inlet 19.

[0026] Furthermore, the elastic connection mechanism includes a movable circular plate 12 and a spring 13. The movable circular plate 12 is movably installed in the cylinder chamber 11.

[0027] Specifically, the detection mechanism includes a mounting rod 16 and a contact pressure sensor 17. One end of the mounting rod 16 is fixedly installed on the inner wall of the top side of the cylinder chamber 11, and the other end of the mounting rod 16 is fixedly installed with a contact pressure sensor 17. The contact point of the contact pressure sensor 17 is located on the top side of the movable circular plate 12. When the top side of the movable circular plate 12 rises and abuts against the contact point at the bottom end of the contact pressure sensor 17, at this time, the contact pressure sensor 17 detects a blockage signal in the rotating sieve barrel 4.

[0028] Further, the discharging driving mechanism includes a second motor 20, a driving rod 21 and a spiral conveyor blade 22. The second motor 20 is fixedly installed on the top side of the mounting frame 9. One end of the driving rod 21 is fixedly installed on the output shaft of the second motor 20. The other end of the driving rod 21 extends into the discharging pipe 18 and is fixedly installed with the spiral conveyor blade 22. By starting the second motor 20, the driving rod 21 drives the spiral conveyor blade 22 to rotate in the discharging pipe 18. The sundries accumulated at the bottom of the rotating sieve barrel 4 are conveyed upward in the discharging pipe 18 through the feeding port 19 until the sundries accumulated at the bottom of the rotating sieve barrel 4 are discharged from the discharging end of the discharging pipe 18 to the outside world.

[0029] Specifically, the controller 23 is electrically connected to the contact pressure sensor 17 and the second motor 20, and the controller 23 is electrically connected to the first motor 7. When the contact pressure sensor 17 detects a blockage signal in the rotating sieve barrel 4 at this time and transmits it to the controller 23, the second motor 20 is started by the controller 23.

[0030] During use: When the rotating sieve barrel 4 is treating domestic sewage, some sundries are filtered by the filter screen in the rotating sieve barrel 4, which hinders the normal filtration of domestic sewage by the rotating sieve barrel 4. When the sundries in the rotating sieve barrel 4 accumulate to a certain height, the floating block 15, the connecting rod 14 and the movable circular plate 12 are pushed upward, causing the spring 13 to be deformed and compressed. When the top side of the movable circular plate 12 rises and abuts against the contact point at the bottom end of the contact pressure sensor 17, the contact pressure sensor 17 detects a blockage signal in the rotating sieve barrel 4 at this time and transmits it to the controller 23. The second motor 20 is started by the controller 23, so that the driving rod 21 drives the spiral conveyor blade 22 to rotate in the discharging pipe 18. The sundries accumulated at the bottom of the rotating sieve barrel 4 are conveyed upward in the discharging pipe 18 through the feeding port 19 until the sundries accumulated at the bottom of the rotating sieve barrel 4 are discharged from the discharging end of the discharging pipe 18 to the outside world.

[0031] In summary, by arranging a floating block 15 in the rotating sieve barrel 4, when the sundries accumulated during the filtration of domestic sewage in the rotating sieve barrel 4 reach a certain height, the floating block 15, the connecting rod 14 and the movable circular plate 12 are pushed to move upward, so that the top side of the movable circular plate 12 rises and abuts against the contact point at the bottom end of the contact pressure sensor 17. The contact pressure sensor 17 detects that a blockage signal is generated in the rotating sieve barrel 4 at this time and transmits it to the controller 23. The controller 23 starts the second motor 20, so that the driving rod 21 drives the spiral conveying blade 22 to rotate in the discharge pipe 18. The sundries accumulated at the bottom in the rotating sieve barrel 4 are conveyed upward in the discharge pipe 18 through the spiral conveying blade 22 until the sundries accumulated at the bottom in the rotating sieve barrel 4 are discharged from the discharge end of the discharge pipe 18 to the outside. Thus, the automatic cleaning of the filtered and accumulated sundries in the rotating sieve barrel 4 is intelligently realized without manual intervention, with a relatively high degree of intelligent automation, and at the same time, the working efficiency of the domestic sewage treatment by the sewage treatment filter tank 1 is improved.
