Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment devices, and more particularly to a sewage treatment device with a filtering mechanism. Background Art

[0002] The sewage treatment device is one of the equipments specially used for sewage treatment. Among them, the common sewage treatment device is mainly composed of water inlet device, pretreatment unit, biological treatment unit, deep treatment unit, sludge treatment unit, water outlet device and control system. The specific working process of the sewage treatment device is as follows: 1. Pretreatment: sewage enters the water inlet device, and the large particles of impurities in the sewage are removed through the internal grille; 2. Biological treatment: sewage enters the aeration tank, and the aeration system provides sufficient oxygen to promote microbial degradation of organic matter; 3. Deep treatment: sewage after biological treatment enters the deep treatment unit, and trace harmful substances are removed by activated carbon adsorption, ozone oxidation and other methods; 4. Sludge treatment: the sludge generated in the biological treatment process enters the sludge treatment unit for treatment; 5. Effluent and disinfection: the treated sewage is discharged or reused through the effluent device; In actual operation, we found that the grid inside the water inlet device is prone to clogging. The common method for this situation is to use a mechanical structure to drive a scraping device to scrape and clean the surface of the grid. However, in actual use, we found that the device can only remove impurities on the surface of the grid, while impurities in the grid filter holes cannot be cleaned in time, so the cleaned grid is still clogged, which leads to a decrease in the overall efficiency of the sewage treatment device. Therefore, we are in urgent need of a sewage treatment device with a filtering mechanism to solve the above-mentioned problems. Summary of the invention

The two sets of clamping plates 509 are vertically installed with auxiliary springs near the first clamping plate 504. A set of auxiliary springs are vertically installed with a pressure sensor 511 at one end away from the corresponding clamping plate 509. The sewage passes through the outer surface of the grid 503 to generate an additional squeezing force, which is transmitted to the surface of the pressure sensor 511 through a set of clamping plates 509 and a set of auxiliary springs.

[0027] In the embodiment of the present application, the edge of the auxiliary filter plate 505 is in an inclined state, which is conducive to scraping and cleaning the inner wall of the main conveying pipe 3.

[0028] The specific working process of the embodiments of this part of the application is as follows: when the control system determines that the grille 503 is blocked, the control system controls the second electric hydraulic column 516 and the third electric hydraulic column 519 to input a stable working current, and the third electric hydraulic column 519 drives the support plate 517 and the limit frame 520 to drive the auxiliary scraping plate 512 to contact the water-facing surface of the grille 503 to scrape and clean the impurities on the surface. When the third electric hydraulic column 519 drives the main scraping plate 514 and the auxiliary scraping plate 512 to move to the position of the first clamping plate 504, the main scraping plate 514 contacts the edge of the first clamping plate 504. At this time, the main scraping plate 514 rotates ninety degrees clockwise, and at the same time, the support plate 517 contacts the surface of the auxiliary filter plate 505. At this time, the second hollow rubber plate 518 and the support plate 517 will form an isolation mechanism inside the preliminary filter box 5, and the preliminary filter box 5 is isolated into two groups of independent storage spaces; the second electric hydraulic column 516 inputs a stable working current to drive the hollow telescopic plate 515 to stretch. When the hollow telescopic plate 515 contacts the inner side of the bottom of the preliminary filter box 5, the hollow telescopic plate 515 and the second hollow rubber plate 518 and the support plate 517 will form an independent storage space, and the grille 503 is in the storage space. At this time, the adsorption pump 6 inputs a stable working current to generate compressed air, which is input into the hollow telescopic plate 515 through a group of air outlets of the conveying pipe 603, and is input into the filter holes of the grille 503 through the air outlet holes on the surface of the hollow telescopic plate 515, and the blockages in the filter holes are cleaned by wind. At the same time, the solenoid valve inside the conveying pipe 603 is in an open state, and the impurities cleaned in the independent space are input into the storage cylinder 602 through the conveying pipe 603 for storage management; When the control system determines that the grille 503 is damaged, the first electric hydraulic column 507 inputs a stable working current to drive the first clamping plate 504 and the grille 503 to move upward. When the first clamping plate 504 moves to the top position of the preliminary filter box 5, the staff can manually pull the grille 503 for corresponding replacement. At the same time, the auxiliary filter plate 505 can be driven to move upward during the movement of the first clamping plate 504. The auxiliary filter plate 505 scrapes part of the inner wall of the preliminary filter box 5 to clean the impurities on the inner wall of this part. At the same time, during the rise of the auxiliary filter plate 505, large impurities remaining on its upper surface can be filtered, and the scraped impurities and some large impurities move to the top of the preliminary filter box 5 together with the auxiliary filter plate 505. After the auxiliary filter plate 505 moves to the designated area, the adsorption pump 6 inputs a stable working current to generate adsorption force, and moves to the inside of the storage cylinder 602 through another set of air outlets of the three-way pipe 601, and then is transported to the surface of the auxiliary filter plate 505 through the U-shaped delivery pipe 604, and the impurities remaining on the surface are adsorbed and cleaned.

The control system simulates the simulated pressure data generated by the pressure sensor 511 when the grille 503 is in a normal working state, and integrates the simulated pressure data to form a threshold range. The control system compares the real-time pressure data with the threshold range. When the real-time pressure data is less than the threshold range, it is determined that the grille 503 is damaged. When the real-time pressure data is greater than the threshold range, it is determined that the grille 503 is blocked.

[0031] In the embodiment of the present application, after the grille 503 is cleaned, the control system compares the real-time pressure data with the threshold range for a second time. When the real-time pressure data is still greater than the threshold range, it is determined that the grille 503 is damaged. When the control system detects that the grille 503 is damaged, it controls its internal communication device to remotely send a warning message to the staff, reminding them to go to the site for inspection.

At the same time, the auxiliary filter plate 505 can be driven to move upward during the movement of the first clamping plate 504. The auxiliary filter plate 505 scrapes part of the inner wall of the preliminary filter box 5 to clean the impurities on the inner wall of this part. At the same time, during the rise of the auxiliary filter plate 505, large impurities remaining on its upper surface can be filtered, and the scraped impurities and some large impurities move to the top of the preliminary filter box 5 together with the auxiliary filter plate 505. After the auxiliary filter plate 505 moves to the designated area, the adsorption pump 6 inputs a stable working current to generate adsorption force, and moves to the inside of the storage cylinder 602 through another set of air outlets of the three-way pipe 601, and then is transported to the surface of the auxiliary filter plate 505 through the U-shaped delivery pipe 604 to adsorb and clean the impurities remaining on its surface.
