Description

Technical Field

[0001] The invention relates to the technical field of sewage filtration, in particular to a sewage filtration centralized treatment device for water environment monitoring. Background Art

[0002] With the acceleration of urbanization and the improvement of industrialization, water resource protection and management has become a major global issue. Water environment monitoring, as an important part of water resource management, is of great significance for ensuring water quality safety and preventing water pollution.

[0003] During rainfall, rain will directly wash away the streets and roads near the construction site. These surfaces usually accumulate a lot of silt and construction waste. Uncleared silt will enter the sewage pipes under the scouring of rainwater, causing the silt content in the sewage pipes to increase. Since silt and other particulate matter in sewage will affect the determination of indicators such as chemical oxygen demand (COD) and biochemical oxygen demand (BOD), it is necessary to filter the silt in the sewage to ensure the accuracy of the water environment monitoring results. However, a large amount of silt mixed with rainwater enters the sewage pipes during the rainfall period, causing the silt content in the sewage to exceed the filtering capacity of the filtering equipment, causing the silt to gradually accumulate and clog the filtering equipment, resulting in a decrease in the sewage flow in the pipe. The low flow after the blockage will make the collected water samples unable to accurately reflect the actual sewage water quality, resulting in a lack of representativeness of the water samples, affecting the accuracy of the water environment monitoring results. Summary of the invention

[0009] As a preferred solution of the centralized sewage filtration and treatment equipment for water environment monitoring of the present invention, a docking block is provided on the filter ring, an air inlet groove is provided on the docking block, and an air pipe is provided on the filter ring.

[0010] As a preferred solution of the centralized sewage filtration and treatment equipment for water environment monitoring of the present invention, the switching assembly includes a cover body, an arc groove arranged on the cover body, and a key groove arranged in the arc groove.

[0011] As a preferred solution of the centralized sewage filtration and treatment equipment for water environment monitoring of the present invention, a synchronization rod is arranged in the keyway, a synchronization block is arranged on the synchronization rod, and a limit ring is arranged on the synchronization rod.

[0012] As a preferred solution of the centralized sewage filtration and treatment equipment for water environment monitoring described in the present invention, the cover body is provided with a rotating rod, a rotating disk arranged on the rotating rod, a swing rod arranged on the rotating rod, and a contact block arranged on the swing rod.

[0013] As a preferred solution of the centralized sewage filtration and treatment equipment for water environment monitoring of the present invention, a telescopic block is arranged in the contact block, and an air outlet groove is arranged in the telescopic block.

[0014] As a preferred solution of the centralized sewage filtration and treatment equipment for water environment monitoring described in the present invention, the driving assembly includes a fixed rod, a movable rod arranged outside the fixed rod, a movable block arranged on the movable rod, a movable groove 1 arranged on the movable block, and a movable groove 2 arranged on the movable block.

[0015] As a preferred solution of the centralized sewage filtration and treatment equipment for water environment monitoring described in the present invention, the driving assembly further includes a semi-arc plate, a semi-arc ring arranged on the semi-arc plate, and an intermittent rod arranged on the semi-arc plate.

[0016] As a preferred solution of the centralized sewage filtration treatment equipment for water environment monitoring of the present invention, the clarification component includes a substrate, a clarification tank arranged on the substrate, a stirring tank arranged in the clarification tank, a feeding tank arranged in the clarification tank, a feeding cavity arranged in the feeding tank, and an adjusting rod arranged in the feeding tank.

[0017] The clarification component also includes a driving cylinder, a driving plate arranged in the driving cylinder, a feeding plate arranged on the driving plate, a supporting plate arranged on the driving plate, a clamping ring arranged on the driving cylinder, and a paddle arranged on the clamping ring.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By arranging partitions in an array on the filter cartridge and controlling the intermittent rotation of the filter cartridge by using a driving assembly, part of the filter holes of the filter cartridge will no longer clean the sewage after filtering part of the sewage under the rotation of the filter cartridge. At this time, the other part of the filter holes of the filter cartridge will filter the sediment in the sewage under the rotation of the filter cartridge, thereby avoiding the increase of sediment content in the sewage during the rainy period, resulting in sediment accumulation and clogging the filter cartridge, affecting the flow rate of sewage after filtration, and improving the measurement accuracy of water environment monitoring results;

[0020] 2. At the same time, the rotation of the filter cartridge drives the guide plate and the piston plate to rise, so that the gas in the air pressure cylinder enters the rodless cylinder through the switching component, so that the scraper bar sweeps the surface of the filter cartridge that is not currently involved in sewage filtration and has previously participated in sewage filtration, thereby scraping off the silt attached to the surface of the filter cartridge. At the same time, the rotation of the filter cartridge drives the partition plate, causing the partition plate to push the silt scraped off by the scraper bar to the discharge port, so that the silt is discharged from the guide plate under the action of its own gravity, avoiding the gradual accumulation of silt in the area between the filter cartridge and the working column, thereby improving the filtering effect of the filter cartridge;

[0021] 3. The rotation of the filter cartridge drives the moving rod to move, so that the feeding plate presses the adjusting rod, and the adjusting rod rotates under the thrust of the feeding plate, so that the flocculant in the feeding chamber enters the feeding tank from the liquid outlet groove, and then the feeding plate is driven up by the moving rod. At this time, the adjusting rod re-blocks the liquid outlet groove, and the flocculant entering the feeding tank will be discharged into the stirring tank through the one-way valve, so that the suspended particles and colloids in the sewage from which the sediment is filtered out are flocculated by the flocculant, and the liquid level in the stirring tank is higher than the liquid level in the clarification tank, so that the clarified sewage overflows into the diversion groove and is discharged through the diversion port. The sewage becomes clarified through the flocculation effect of the flocculant, avoiding the turbid water sample interfering with the light path and affecting the absorbance measurement when using a spectrophotometer to detect trace organic matter in the sewage;

[0022] 4. The driving plate drives the support plate to move synchronously, so that when the driving plate rotates, the support plate will drive the clamping ring and the paddles arranged on the clamping ring to rotate, so that the paddles disturb the fluid in the stirring tank, promote the mixing of flocculant and sewage, and at the same time, the driving assembly drives the movable block to rotate intermittently, so that the paddles rotate intermittently, avoiding the paddles from disturbing the water body too violently, so that the flocculent flocs are broken up by the shear force of the fluid, causing the clarified water body to become turbid again.

The cover 341 is connected to one end of the air cylinder 33 away from the guide cylinder 32 , and a fixing shell is disposed on the cover 341 .

[0049] A synchronization rod 344 is arranged in the key slot 343, a synchronization block 345 is arranged on the synchronization rod 344, and a limit ring 346 is arranged on the synchronization rod 344.

[0050] The cover body 341 is provided with a rotating rod 347, a rotating disk 3471 arranged on the rotating rod 347, a swing rod 3472 arranged on the rotating rod 347, and a contact block 348 arranged on the swing rod 3472. The rotating rod 347 is rotatably connected to the cover body 341, the rotating disk 3471 is rotatably connected to the rotating rod 347, the rotating disk 3471 is arranged inside the air pressure cylinder 33, a spring four is sleeved on the outer side of the rotating rod 347, one end of the spring four is connected to the cover body 341, and the other end is connected to the rotating disk 3471, a rotating hole is arranged in the rotating rod 347, a swing hole is arranged in the swing rod 3472, and the rotating hole is connected to the inside of the swing hole, the contact block 348 is arranged at one end of the swing rod 3472 away from the rotating rod 347, a contact groove is arranged in the contact block 348, an elastic groove is arranged in the contact block 348, the contact groove is connected to the inside of the elastic groove, and the contact groove is connected to the inside of the swing hole.

[0051] A telescopic block 349 is provided in the contact block 348, and an air outlet groove 3491 is provided in the telescopic block 349. The telescopic block 349 is slidably set in the elastic groove. A spring five is connected to the end of the telescopic block 349 close to the elastic groove, and the end of the spring five away from the telescopic block 349 is connected to the bottom of the elastic groove. Initially, the spring five pushes the telescopic block 349. At this time, the air outlet groove 3491 is located in the slot area close to the elastic groove, causing the contact groove and the air outlet groove 3491 to be misaligned, and the telescopic block 349 blocks the contact groove. When the spring five is deformed and compressed, the air outlet groove 3491 coincides with the contact groove, and the gas can enter the air outlet groove 3491 from the contact groove, and when the docking block 261 rotates to contact the contact block 348, the air outlet groove 3491 can coincide with the air inlet groove 262.

[0052] During use, the sewage pipe is first connected to the mounting plate, and the sewage enters the inner area of ​​the working column 23 through the water inlet groove. At this time, the sewage will enter the inner side of the filter cartridge 24 through the filter holes on the filter cartridge 24, and enter the clarification component 4 through the water outlet groove on the bottom plate 22;

[0053] The filter cylinder 24 is controlled to rotate by the driving assembly 21, and the guide cylinder 32 will rotate synchronously with the filter cylinder 24, so that during the rotation of the guide cylinder 32, the fixed plate 31 limits the moving rod 35, causing the sliding shaft 361 on the guide plate 36 to slide along the spiral groove 321. At this time, the guide plate 36 will move in a direction away from the bottom plate 22, and the moving rod 35 will move synchronously with the guide plate 36. Once the spring is deformed, the piston plate 351 will be pushed by the moving rod 35.

[0054] At the same time, the filter ring 26 rotates synchronously with the filter cartridge 24, and the docking block 261 will push the contact block 348, so that the rotating rod 347 rotates, and the swing rod 3472 and the contact block 348 move synchronously with the docking block 261, and the spring three is deformed, causing the spring five to deform, and the telescopic block 349 is compressed into the elastic groove under pressure. At this time, the air outlet groove 3491 is connected with the inside of the contact groove, and the air inlet groove 262 overlaps with the air outlet groove 3491 and communicates with each other. At this time, the gas in the air pressure cylinder 33 will pass through the rotating hole, the swing hole, the contact groove, the air outlet groove 3491, the air inlet groove 262, and finally enter the air pipe 27;

[0055] Then, the gas in the air pipe 27 drives the piston in the rodless cylinder 37 to shift, causing the limit block 372 to drive the scraper bar 373 to slide along the limit rod 371, and the spring 2 is deformed. At this time, the scraper bar 373 will scrape the sediment remaining on the surface of the filter cartridge 24, so that the sediment on the surface of the filter cartridge 24 is separated from the surface of the filter cartridge 24 and finally falls onto the bottom plate 22. As the partition plate 25 shifts synchronously with the filter cartridge 24, the sediment separated from the filter cartridge 24 is pushed to the area of ​​the discharge port 221 by the partition plate 25, so that the sediment separated from the sewage falls onto the guide plate through the discharge port 221, and the sediment slides out from the guide plate under the action of its own gravity.

[0056] At the same time, when the piston plate 351 moves to contact the rotating disk 3471, the rotating disk 3471 will be pushed up by the piston plate 351, the spring four is deformed, the docking block 261 is separated from the contact block 348, and the rotating rod 347 is displaced in the opposite direction to the docking block 261 under the action of the return elastic force of the spring three. At this time, the sliding shaft 361 moves to the return groove 322, and the return elastic force of the spring one pulls the guide plate 36, the piston plate 351, and the moving rod 35 to return to their original positions. The piston plate 351 is separated from the rotating disk 3471, and the rotating disk 3471 and the rotating rod 347 are returned to their original positions under the return elastic force of the spring four.

[0057] As the docking block 261 is separated from the contact block 348, the internal air pressure of the rodless cylinder 37 is released from the air inlet groove 262. At this time, the spring 2 pushes the limit block 372 and the scraper strip 373 is reset.

[0058] During the rotation of the rocker arm 3472 , the synchronization rod 344 will slide along the arc groove 342 . When the piston plate 351 pushes the turntable 3471 to make the turntable 347 synchronously shift, the rocker arm 3472 will slide linearly along the limiting groove in the limiting ring 346 .

[0071] The driving cylinder 47 is provided at one end of the feeding tank 44 away from the base plate 41, and a driving groove is arranged in an array inside the driving cylinder 47. A guide block is symmetrically arranged on the driving plate 48. The driving plate 48 is slidably arranged in the driving cylinder 47, and the guide block is slidably arranged in the driving groove. One side of the driving plate 48 is connected to the moving rod 35. One end of the spring is connected to the bottom plate 22, and the other end is connected to the driving plate 48. A plug rod is connected to one side of the driving plate 48 away from the moving rod 35. The plug rod passes through the feeding tank 44. The end of the plug rod away from the driving plate 48 is connected to the feeding plate 481, and the feeding plate 481 is slidably arranged in the feeding tank 44.

[0072] The support plate 482 is arranged on a side of the driving plate 48 close to the moving rod 35, and support grooves are symmetrically opened on the support plate 482. The snap ring 49 is rotatably arranged at the end of the driving cylinder 47 away from the feeding tank 44. The snap ring 49 is slidably arranged in the support groove, and the paddles 491 are symmetrically arranged on the snap ring 49.

[0073] During use, the water discharged from the water outlet tank enters the mixing tank 43 through the water guide plate, and slides along the guide groove through the sliding shaft 361 on the guide plate 36, causing the moving rod 35 to perform linear reciprocating lifting and lowering motion;

[0074] When the moving rod 35 descends, the guide block on the driving plate 48 will slide along the driving groove, and the driving plate 48 will rotate at this time, and the support plate 482 will rotate synchronously with the driving plate 48, and at the same time, the driving plate 48 will move toward the direction of the base plate 41, so that the driving plate 48 drives the feeding plate 481 to slide in the feeding tank 44, and then the feeding plate 481 will push the adjusting rod 46, and the torsion spring will deform. At this time, the adjusting rod 46 will no longer block the liquid outlet groove. At this time, the flocculant in the feeding chamber 45 enters the control groove and the inside of the feeding tank 44 through the liquid outlet groove;

[0075] When the moving rod 35 rises, the feeding plate 481 will rise. During the rising process of the feeding plate 481, the feeding plate 481 will push the adjusting rod 46 and separate from the adjusting rod 46. At this time, the adjusting rod 46 will re-block the liquid outlet tank under the elastic force of the torsion spring. The feeding plate 481 carries a certain amount of flocculant and moves toward the direction of the one-way valve. Finally, the flocculant is discharged into the stirring tank 43 through the one-way valve.

[0076] During the lifting and rotating process of the driving plate 48, the support plate 482 will move simultaneously with the driving plate 48. At this time, the retaining ring 49 will rotate synchronously with the driving plate 48 driven by the support plate 482, causing the paddle 491 to rotate. The rotation of the paddle 491 will disturb the water body and flocculant in the stirring tank 43. Under the action of the flocculant, the suspended particles and colloids in the water body will coagulate and settle, and then the clarified water body will enter the clarification tank 42 through the stirring tank 43. Since the liquid level in the stirring tank 43 is higher than the liquid level in the clarification tank 42, the water in the clarification tank 42 overflows into the diversion tank and is discharged through the diversion port.

[0077] The remaining structure is the same as that of Example 2.
