Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a purification device for river and lake ecological restoration. Background Art

[0002] Lake pollution refers to the phenomenon that lakes are polluted due to the influx of sewage. When the amount of sewage flowing into a lake exceeds the self-purification capacity of the lake, the water quality of the lake changes, causing the lake environment to deteriorate seriously. There are organic matter and heavy metals suspended on the water surface, and some organic matter is difficult to dissolve in water. Silt, clay, organic matter, algae and microorganisms, etc. are one of the indicators to measure the degree of water pollution.

[0003] Most of the existing ecological restoration purification devices use large-scale water pumping for water source treatment when dealing with suspended matter, but it is easy to damage the ecological environment of the biota and cause fish losses. The suspended matter purification efficiency is low, and the cost of using the device is high. Small devices will become clogged after a certain period of use and need to be shut down for cleaning. In addition, heavy metals or other organic matter in the water cannot be completely cleaned.

[0037] In this embodiment, the unloading mechanism 3 includes a mounting bracket 31 fixedly connected to the sewage tank 15, and a storage box 32 is fixedly connected to one side of the servo motor 33 at the upper end of the mounting bracket 31, and a first fixed bracket 310 is fixedly connected to the inner side of the discharge port of the storage box 32, and the lower end of the first fixed bracket 310 is fixedly connected to a return rope 327, and the lower end of the return rope 327 is fixedly connected to a second fixed bracket 312, and the outer side of the second fixed bracket 312 is fixedly connected to a first feed pipe 313, and the lower end of the first feed pipe 313 is fixedly connected to the sewage tank 15, and the outer side of the return rope 327 is fixedly connected to a block 311, which is spherical, and the outer side of the block 311 fits the discharge port of the storage box 32.

[0038] Specifically, the rotating rod 37 drives the sweeping plate 314 to move back and forth, and the sweeping plate 314 will touch the return rope 327, and pull the stopper 311 open through the return rope 327, so that the activated carbon inside the storage box 32 falls into the first feed pipe 313, and then enters the sewage tank 15 through the first feed pipe 313 to mix with the sewage to absorb the floating objects. The first fixed bracket 310 and the second fixed bracket 312 limit the position of the return rope 327. After the sweeping plate 314 staggers the return rope 327, the return rope 327 drives the stopper 311 to reset, so as to avoid wasting activated carbon and make the activated carbon fully mixed.

[0039] In this embodiment, the outer side of the fixed rotating shaft 35 is rotatably connected to the first sleeve 315, the outer side of the first sleeve 315 is fixedly connected to the third connecting rod 316, one end of the third connecting rod 316 is fixedly connected to the clamping plate 317, the inner side of the clamping plate 317 is rotatably connected to the second sleeve 318 through the rotating shaft, the outer side of the second sleeve 318 is fixedly connected to the fourth connecting rod 319, the outer side of the fourth connecting rod 319 is slidably connected to the limited baffle 328, the front and rear ends of the limited baffle 328 are fixedly connected to the mounting bracket 31, and one end of the fourth connecting rod 319 is fixedly connected to the mounting bracket 31. A fifth connecting rod 320 is fixedly connected, and a separation tank 322 is slidably connected to the outer side of the fifth connecting rod 320. A second scraper 323 is fixedly connected to the inner side of the separation tank 322 at one end of the fifth connecting rod 320, a filter plate 321 is fixedly connected to the inner side of the separation tank 322, a reflux pipe 325 is fixedly connected to the lower end of the separation tank 322, a collecting pipe 324 is fixedly connected above the outer filter plate 321 of the separation tank 322, a collecting box 326 is fixedly connected to the lower end of the collecting pipe 324, and the collecting box 326 is fixedly connected to the inner side of the second mounting box 2.

[0040] Specifically, the sewage containing impurities is diverted to the separation tank 322 through the diversion pipe 411, and then the filter plate 321 filters the sewage so that the impurities are present above the filter plate 321. The filtered water enters the return pipe 325 and then flows back to the second feed pipe 41. When the servo motor 33 rotates, the first sleeve 315 on the outer side of the fixed shaft 35 is driven, and the first sleeve 315 is connected to the clamping plate 317 through the third connecting rod 316. The clamping plate 317 drives the second sleeve 318 through the rotating shaft, and the second sleeve 318 drives the fourth connecting rod 319. The limit baffle 328 limits the position of the fourth connecting rod 319, so that the fourth connecting rod 319 maintains a linear sliding. The fourth connecting rod 319 drives the second scraper 323 to slide back and forth on the upper end of the filter plate 321 through the fifth connecting rod 320, thereby cleaning the filtered impurities, so that the impurities enter the collection pipe 324 and are concentrated in the collection box 326 for recycling.

[0041] In this embodiment, the filter plate 321 is designed with a symmetrical inclined angle, and the lower end of the second scraper 323 is in contact with the upper end of the filter plate 321 .

[0042] Specifically, the filter plate 321 is designed with a symmetrical inclined angle, which can concentrate impurities at the middle angle of the filter plate 321, so that the cleaning efficiency of the second scraper 323 is higher, and the sewage and impurities can be separated quickly.

[0043] In this embodiment, the filtering mechanism 4 includes a second feed pipe 41 fixedly connected to the output port of the second sewage pump 16, the outer side of the second feed pipe 41 is fixedly connected to the return pipe 325 near the upper part, the upper end of the second feed pipe 41 is fixedly connected to a buffer tank 410, the inner side of the buffer tank 410 is fixedly connected to a first fixed plate 42 near the upper end, the upper end of the first fixed plate 42 is installed with a cylinder 43, the output shaft of the cylinder 43 is fixedly connected to a pressure plate 48, and a filter cartridge 47 is provided on the inner side of the buffer tank 410, and the outer wall of the pressure plate 48 does not fit the inner wall of the filter cartridge 47.

[0044] Specifically, the second sewage pump 16 outputs sewage to the outside, allowing the sewage to enter the second feed pipe 41 and then enter the buffer tank 410. The first fixed plate 42 is used for the installation of the cylinder 43 and the closing of the buffer tank 410. The pressure plate 48 is pressed downward to two-thirds of the filter cartridge 47 through the cylinder 43 and then pressed back and forth. The water pressure under the pressure plate 48 will increase and be output upward through the space between the pressure plate 48 and the filter cartridge 47, and the inner wall of the filter cartridge 47 is flushed with the pressurized water pressure.

[0045] In this embodiment, the lower end of the first fixed plate 42 is fixedly connected to two groups of symmetrical fixed rods 44, and the two groups of fixed rods 44 are commonly fixedly connected to the second fixed plate 45. The outer side of the second fixed plate 45 is in contact with the inner wall of the buffer tank 410. The lower ends of the two groups of fixed rods 44 are commonly fixedly connected to a circular scraper 46. The outer side of the circular scraper 46 is in contact with the inner wall of the buffer tank 410. Brushes are provided on both the inner and outer sides of the circular scraper 46. The inner side of the circular scraper 46 is in contact with the outer wall of the filter cartridge 47.

[0046] Specifically, after the second fixing plate 45 is installed, it presses the filter cartridge 47 to prevent cross-flow and divides the internal space of the buffer tank 410 into two parts. When the first fixing plate 42 is disassembled and pulled out, the fixing rod 44 can drive the circular scraper 46 to stretch outward together and clean the inner wall of the buffer tank 410 and the outer side of the filter cartridge 47 by sliding. After the upper end of the circular scraper 46 is fitted with the filter cartridge 47, the filter cartridge 47 is pulled out together.

[0047] In this embodiment, a discharge pipe 49 is fixedly connected below the second fixed plate 45 on the outside of the buffer tank 410, a pressure gauge is installed on the outside of the discharge pipe 49, a diversion pipe 411 is fixedly connected above the second fixed plate 45 on the outside of the buffer tank 410, the lower end of the diversion pipe 411 is fixedly connected to the separation tank 322, and a solenoid valve is installed on the outside of the diversion pipe 411.

[0048] Specifically, when the treatment is continued, the output water pressure change can be detected by the pressure gauge on the outside of the discharge pipe 49, and it can be determined whether the filter cartridge 47 is blocked. The solenoid valve of the diversion pipe 411 is opened to divert the sewage and allow part of the sewage to enter the separation tank 322 for treatment.

[0049] In this embodiment, the front end of the first installation box 1 is fixedly connected to the third fixed plate 5, the upper end of the third fixed plate 5 is installed with an electric telescopic rod 6, the output shaft of the electric telescopic rod 6 is fixedly connected to a hose 8 through a sleeve, the upper end of the hose 8 is fixedly connected to a first water pumping pipe 7, the first water pumping pipe 7 is fixedly connected to the input port of the first sewage pump 14, and the lower end of the hose 8 is fixedly connected to a second water pumping pipe 9.

[0050] Specifically, the third fixing plate 5 provides installation and fixation for the electric telescopic rod 6, and the output shaft of the electric telescopic rod 6 is used to pull the hose 8 to adjust the height of the second water pumping pipe 9, so that the input port of the second water pumping pipe 9 is submerged above the water surface, and the first sewage pump 14 is started, so that floating objects on the water surface are pumped into the sewage tank 15 together with the water through the first water pumping pipe 7.

[0051] Working principle: when in use, the device is pushed into the water through the roller 12, and then the air bag 11 is used to make the device float on the water surface. After starting the propeller 13, the remote control device is moved on the water surface. The electric telescopic rod 6 installed on the upper end of the third fixed plate 5 is started, and the height of the second water pumping pipe 9 is adjusted by using the electric telescopic rod 6 and the hose 8, so that the input port of the second water pumping pipe 9 is submerged above the water surface. The first sewage pump 14 is started, so that the floating objects on the water surface are pumped into the sewage tank 15 together with the water through the first water pumping pipe 7. The servo motor 33 is started, so that the output shaft of the servo motor 33 drives the first connecting rod 34 to rotate, the first connecting rod 34 drives the fixed rotating shaft 35 to rotate, the fixed rotating shaft 35 drives the second connecting rod 36 to rotate, and the second connecting rod 36 drives the rotating rod 37 to rotate. The rotating rod 37 stirs the sewage inside the sewage tank 15 through the stirring plate 38, and uses the first scraper 39 to prevent the inner wall of the sewage tank 15 from missing pollutants during stirring. The rotating rod 37 drives the sweeping plate 314 to move back and forth. The sweeping plate 314 touches the pull-back rope 327, and pulls the stopper 311 open through the pull-back rope 327, so that the active carbon inside the storage box 32 falls into the first feeding pipe 313, and then enters the sewage tank 15 through the first feeding pipe 313 to mix with the sewage to absorb floating objects. The first fixed bracket 310 and the second fixed bracket 312 limit the position of the pull-back rope 327. After the sweeping plate 314 staggers the pull-back rope 327, the pull-back rope 327 drives the stopper 311 to reset, so as to avoid wasting the activated carbon and fully mix the put-in activated carbon.

[0052] When the sewage in the sewage tank 15 reaches a certain capacity, the second sewage pump 16 is started to output the sewage to the outside, so that the sewage enters the second feeding pipe 41 and then enters the buffer tank 410. The shunt pipe 411 is equipped with an electromagnetic valve in a closed state. After the sewage passes through the filter cartridge 47 to filter impurities, the filtered water is discharged to the lake again through the discharge pipe 49. When the treatment is continued, the output water pressure change can be detected by the pressure gauge on the outside of the discharge pipe 49, so that it can be judged whether the filter cartridge 47 is blocked. After opening the electromagnetic valve of the shunt pipe 411, the cylinder 43 is started to extend the pressure plate 48 into the filter cartridge 47. The pressure plate 48 does not fit the inner wall of the filter cartridge 47. The pressure plate 48 is squeezed downward to two-thirds of the filter cartridge 47 and then pressed back and forth. The water pressure below the pressure plate 48 will increase and be output upward through the space between the pressure plate 48 and the filter cartridge 47. The inner wall of the filter cartridge 47 is flushed by the pressurized water pressure, and the three below the filter cartridge 47 are One-third of the total volume of the buffer tank 410 is backflowed, and the Bernoulli effect causes the sewage below the second fixed plate 45 inside the buffer tank 410 to impact the outer wall of the filter cartridge 47 inwardly, thereby achieving a recoil effect. After the second fixed plate 45 is installed, the filter cartridge 47 is pressed tightly to avoid cross-flow. The first fixed plate 42 is used for the installation of the cylinder 43 and the closing of the buffer tank 410. The first fixed plate 42 drives the second fixed plate 45 through the fixed rod 44 to press the filter cartridge 47, and the internal space of the buffer tank 410 is divided into two parts by the second fixed plate 45. The sewage at the upper end of the second fixed plate 45 contains impurities, and the sewage at the lower end of the second fixed plate 45 is filtered by the filter cartridge 47. When the first fixed plate 42 is disassembled and pulled out, the circular scraper 46 can be driven by the fixed rod 44 to stretch outward together and clean the inner wall of the buffer tank 410 and the outer side of the filter cartridge 47 by sliding, and the filter cartridge 47 is pulled out together after the upper end of the circular scraper 46 is attached to the filter cartridge 47.

[0053] The sewage containing impurities is diverted to the separation tank 322 through the diversion pipe 411, and then the filter plate 321 filters the sewage so that the impurities are present above the filter plate 321. The filtered water enters the return pipe 325 and then flows back to the second feed pipe 41. When the servo motor 33 rotates, the first sleeve 315 on the outer side of the fixed shaft 35 is driven, and the first sleeve 315 is connected to the clamping plate 317 through the third connecting rod 316. The clamping plate 317 drives the second sleeve 318 through the rotating shaft, and the second sleeve 318 drives the fourth connecting rod 319.
