Description

Technical Field

[0001] The invention relates to the technical field of sewage filtration, and in particular to a sewage filtration device and a treatment method for river channel management. Background Art

[0002] With the continuous development of living standards and industrial production, more and more garbage and sewage are continuously discharged into the river, causing the river water to be polluted and the river to become a gathering place for sewage. In order to protect the environment, relevant units need to purify the sewage in the river so that the sewage can be purified for reuse. Filtration is an important process for sewage purification. Traditional filtering devices simply filter the solid waste in the sewage. When the solid waste is large and there are many of them, it is easy to cause clogging of the filtering device, causing the sewage filtration to stagnate and the filtration efficiency to be low. At the same time, the existing filtering devices only focus on filtering the floating objects in the sewage, but ignore the dehydration of the floating objects in the sewage, which makes the existing filtering devices have the problem of sewage residue during processing.

[0003] The announcement number is: CN110734176B, which discloses a purification treatment device for treating river water pollution. The purification device allows the river sewage to be purified to enter the interior of the dehydration cylinder through a liquid inlet pipe. After the sewage flows through the dehydration cylinder, floating objects, solid wastes and other impurities in the river water are filtered out through the dehydration cylinder, and the sewage with solid impurities filtered out then enters the purification chamber. When the dehydration cylinder is rotated, dehydration is performed under the action of a centrifuge. After dehydration, the hydraulic rod is manually controlled to work so that the dehydrated solid waste is then discharged. Although the above-mentioned purification device can separate the sewage from the solid impurities, when separating, the sewage is separated by centrifugal force generated by rotating the dehydration cylinder, but when separating, the solid impurities will cling to the inner wall of the dehydration cylinder, and the above-mentioned purification device needs to be manually operated when discharging the solid impurities, which makes it inconvenient to perform continuous work in actual use. Although the above-mentioned dehydration cylinder is tilted, the impurities are not easy to be discharged automatically after centrifugal dehydration, and the staff needs to use tools to assist in discharging, thereby increasing the workload of the staff.

[0004] Based on this, a sewage filtering device and treatment method for river management are now provided, which can eliminate the disadvantages of existing devices. Summary of the invention

After the sewage with solid impurities is filtered by the filter belt 11, the solid impurities are intercepted at the upper end of the filter belt 11, and the filtered sewage is guided by the two liquid guide plates 14 and flows into the bottom of the filter chamber.

[0037] The switching mechanism includes a worm gear 34, which is fixed on a rotating shaft at one end of the mounting shaft 22, and the rotating shafts at both ends of the mounting shaft 22 are rotatably arranged in the rotating holes on the inner side of the outer box body 13. A worm 35 is meshed on the worm gear 34, and a first rotating plate is rotatably arranged on the rotating shafts at both ends of the worm 35. The first rotating plates are fixed on one side of the outer box body 13, and the rotating shaft at one end of the worm 35 is fixedly connected to the output end of the second motor 36. The second motor 36 is fixed on one side of the outer box body 13. A circular plate is slidably arranged at one end of the connecting tube 21, and a first return spring 26 is arranged between one side of the circular plate and one end of the first spring telescopic rod 24.

When the sewage water level in the first liquid tank 42 drops, the push frame 55 gradually returns to the initial position under the action of the second counterweight. Since the rotating top frame 53 is rotatably connected with the output end of the third spring telescopic rod 54, when the output end of the third spring telescopic rod 54 is restored, the rotating top frame 53 no longer pushes the guide rod 52 to move.

[0043] Example 2

[0044] The difference from Example 1 is that a recoil pipe 18 is provided at the bottom end of the filter belt 11, and the recoil pipe 18 is arranged above the first guide plate 17. The recoil pipe 18 is fixed inside the outer box body 13, and a plurality of exhaust holes are provided at the bottom end of the recoil pipe 18. The output end of the recoil pipe 18 is connected with the output end of the air pump 19. When in use, after the filter belt 11 transports solid impurities to the inside of the collecting box 20, the scraper 16 can clean the solid impurities attached to the outside of the filter belt 11. Then, after the filter belt 11 continues to rotate to the bottom of the recoil pipe 18, the exhaust holes of the recoil pipe 18 discharge air, so that the filter holes on the filter belt 11 are recoiled, so that the solid impurities in the filter holes of the filter belt 11 fall onto the first guide plate 17, and under the action of the gas, the solid impurities on the first guide plate 17 fall into the inside of the collecting box 20.

[0045] The above embodiment discloses a sewage filtering device for river management, wherein, when it is necessary to filter the river sewage, the sewage is added to the outer box body 13 through the liquid inlet pipe, and then the first motor 12 is started, and the first motor 12 drives the filter belt 11 to rotate. After the sewage with solid impurities passes through the filter belt 11 and is filtered, the solid impurities are intercepted at the upper end of the filter belt 11, and the filtered sewage is guided by two liquid guide plates 14 and flows into the bottom end of the filter chamber. When the filter belt 11 rotates, the solid impurities are transported to the inside of the collection box 20 below one end of the filter belt 11. As the solid impurities in the collection box 20 increase, the weight of the upper end of the sliding bottom plate 23 increases. When one end of the sliding push rod 25 squeezes the squeezing button 27, the control box 28 starts the second motor 36, so that the output end of the second motor 36 drives the mounting shaft 22 to rotate 120 degrees, so that the other end of the second motor 36 is pressed. The collecting box 20 is switched, and during the switching process, the baffle plate 32 can close the open end of the collecting box 20, the guide plate 30 guides the fixed column 29, and the fixed column 29 drives the first spring telescopic rod 24 to slide inside the connecting pipe 21, and the first spring telescopic rod 24 pushes the sliding bottom plate 23 to move, so that the sliding bottom plate 23 squeezes the solid impurities inside the collecting box 20, so that the sewage is discharged into the bottom end of the filter chamber. When the open end of the collecting box 20 is separated from the baffle plate 32, under the action of the first spring telescopic rod 24, the sliding bottom plate 23 is pushed to slide inside the collecting box 20, and the sliding bottom plate 23 pushes out the solid impurities inside the collecting box 20, so that the solid impurities are guided by the second guide plate 37 and fall into the collecting cart 38 for automatic collection. At the same time, the sliding bottom plate 23 can scrape off the solid impurities attached to the inner side of the collecting box 20 when sliding;

[0046] Subsequently, the input end of the water pump 41 continuously draws sewage from the filter chamber into the first liquid tank 42. As the water level in the first liquid tank 42 increases, the first floating plate 56 drives the fifth fixed plate to be in close contact with one end of the push frame 55. The fifth fixed plate pushes the output end of the third spring telescopic rod 54 to contract through the push frame 55. At the same time, the output end of the third spring telescopic rod 54 drives the rotating top frame 53 to move. When the rotating top frame 53 is in close contact with the inclined end of the guide rod 52, under the action of the fourth fixed plate, the rotating top frame 53 drives the sliding plate to move, and the sliding plate drives the sealing baffle 50 to move. The second liquid tank 48 is moved so that the second liquid tank 48 is connected with the second liquid discharge pipe 49, so that the purified sewage in the second liquid tank 48 is discharged. When the rotating top frame 53 is separated from one end of the guide rod 52 and is located above the rotating top frame 53, the sealing baffle 50 returns to the initial position under the action of the second spring telescopic rods 51, and the sewage in the second liquid tank 48 is completely discharged. The interior of the second liquid tank 48 is in a closed state. When the adsorption plate approaches the permanent magnet 59, the permanent magnet 59 causes the second floating plate 58 to drop rapidly, and at the same time, the fixed rod 45 is pulled The movable plug 44 is separated from the output end of the first liquid tank 42, so that the sewage in the first liquid tank 42 flows into the drain tank 43, and the drain tank 43 flows into the second liquid tank 48 through the two first drain pipes 47. At the same time, one end of the limit block 60 is tightly attached to the bottom end of the limit frame 61, so that the fixing rod 45 is fixed. When the water level in the second liquid tank 48 increases, the adsorption plate is separated from the permanent magnet 59. When the permanent magnet 59 drives the second fixing plate 57 to contact with the reset guide block 63, the reset guide block 63 pushes the limit frame 61 to move. When one end of the second fixing plate 57 is in contact with the reset guide When the block 63 is in plane contact, the limit block 60 is completely separated from the limit frame 61. Under the action of the second return spring 46, the block 44 closes the output end of the first liquid tank 42, and the water level inside the second liquid tank 48 no longer increases. When the sewage level inside the first liquid tank 42 drops, under the action of the second counterweight, the push frame 55 gradually returns to the initial position. Since the rotating top frame 53 is rotatably connected to the output end of the third spring telescopic rod 54, when the output end of the third spring telescopic rod 54 is restored, the rotating top frame 53 no longer pushes the guide rod 52 to move.

[0047] At the same time, when the second fixed plate 57 pulls the fixed rod 45 to move, the fixed rod 45 drives the rack to move through the support frame, so that the rack engages with the gear 66 to drive the valve stem of the valve 65 to rotate, so that the valve 65 is in an open state, so that when the sewage inside the first liquid tank 42 enters the second liquid tank 48, the medicine inside the medicine tank 64 can be added to the second liquid tank 48 simultaneously. When the fixed rod 45 returns to the initial position, the valve 65 is in a closed state, and then the air supply machine 69 and the aerator 68 aerate the sewage inside the second liquid tank 48, so that the medicine and the sewage are fully mixed to purify the sewage.
