Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and specifically relates to a sewage treatment device capable of classified collection. Background Art

[0002] The production sewage generated during the production processes of various industries and the domestic sewage generated in people's daily lives need to be treated before being discharged into natural rivers to meet the water quality requirements for discharging into a certain water body or being reused. The existing technology generally uses a dissolved air flotation machine for sewage treatment. A dissolved air flotation machine is a device that uses air flotation technology to treat sewage. It mainly injects tiny bubbles into the sewage, making the suspended substances adhere to the bubbles and float to the water surface, thereby achieving solid-liquid separation.

[0003] A patent application with the publication number CN117585755B discloses a dissolved air flotation slag scraping device, which includes a base frame. Inside the base frame, there are a reaction zone, a contact zone, a scraping structure, and a waste residue pool arranged in sequence from left to right; the reaction zone includes a water inlet opened at one end of the base frame close to the reaction zone. Through the adjustment device, this device can adjust the length of the scraper when the water level in the contact zone rises due to rain, so that while the scraper fully scrapes the floating slag, it will not contact the liquid below the floating slag, and the scraping of the floating slag can be completed before the floating slag overflows the device.

[0004] The above solution still has some problems in actual application. When the above device is in use, it uses air flotation technology to treat sewage. However, when the sewage enters the device, it is often accompanied by a large amount of solid impurities. When these impurities enter the device together with the sewage, they will not only occupy the internal space of the device, reduce the contact efficiency between the bubbles and the suspended substances, affect the air flotation effect, but also easily block some water flow passages, causing water flow blockage. Moreover, these sewage may contain heavy metals and chemical pollutants, and when these impurities are fished out of the sewage, it is very easy to cause harm to the bodies of the operators.

[0005] Therefore, the present invention provides a sewage treatment device capable of classified collection. Summary of the Invention

[0017] The beneficial effects of the present invention are as follows: 1. A sewage treatment device capable of classified collection according to the present invention. When treating sewage, sewage is first poured from the upper end of the feeding frame. At this time, the separation bar is started to rotate. The notches formed on the surface of the separation bar will temporarily store relatively large impurity blocks on the surface, and transfer them from the dropping groove to the inside of the storage cylinder as the separation bar rotates. The sewage that continues to fall will move to the surface of the first inclined plate. Since the first inclined plate is inclined, the sewage will then move to the surface of the second inclined plate, and the sewage will move towards the water outlet on the surface of the second inclined plate and be transferred to the inside of the feeding cavity through the water outlet. During the transfer process, the first waste frame, the second waste frame and the third waste frame will filter the sewage step by step, ultimately greatly reducing the impurity content of the sewage entering the inside of the feeding cavity. Moreover, the first waste frame, the second waste frame and the third waste frame can also classify and collect impurities of different volumes for subsequent cleaning work.

[0018] 2. A sewage treatment device capable of classified collection according to the present invention. When the sewage is transferred to the surface of the second inclined plate for filtration, some non-filterable suspended solids are likely to adhere to the inner wall of the water outlet and eventually accumulate to block the water outlet. Since the sewage cannot be discharged normally at this time, the sewage will gradually move upward and drive the floating ball to move upward. During the movement, the floating ball will abut against the pressing switch and finally transmit a signal to the driver, causing the cutting knife to rotate. During the rotation of the cutting knife, the blocked solid impurities will be broken, thereby ensuring the smoothness of the water outlet. And when the sewage is no longer blocked, the floating ball will automatically descend along with the water level line, causing the cutting knife to stop rotating. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0022] Example 1: As Figures 1 to 8 shown, a sewage treatment device capable of classified collection according to an embodiment of the present invention includes a base frame 1. An inlet chamber 11, a separation chamber 12 and a waste residue chamber 13 are sequentially arranged inside the base frame 1 from left to right. A reaction structure 3 including a bubble pump 32 is arranged inside the inlet chamber 11. A partition board 14 is arranged between the separation chamber 12 and the waste residue chamber 13. A separation structure 2 including a plurality of scrapers 23 is arranged at the upper end of the partition board 14. A collection structure 4 is arranged at the upper end of the inlet chamber 11; the collection structure 4 includes: a feeding frame 401 arranged at the upper end of the inlet chamber 11; a storage cylinder 403 arranged inside the feeding frame 401; a separation strip 402 rotatably connected to the surface of the storage cylinder 403, and a dropping groove 418 is opened at one end of the separation strip 402 close to the storage cylinder 403; a first inclined plate 404 arranged at the lower end of the separation strip 402; a water outlet 424 opened on the side wall of the feeding frame 401; a second inclined plate 405 arranged at the lower end of the first inclined plate 404, and the end of the second inclined plate 405 is close to the water outlet 424. A plurality of notches are opened on the surface of the second inclined plate 405, and the size of the notch increases sequentially in the direction of the water outlet 424; a cutting knife 435 rotatably connected to one end of the feeding frame 401 close to the water outlet 424.

[0023] Specifically, a sewage treatment device capable of classified collection is used to treat sewage. When in use, first pour the sewage into the interior of the feeding frame 401, and at this time start the separation bar 402 to rotate. During the rotation of the separation bar 402, the notches formed on the surface of the separation bar 402 will temporarily store the relatively large impurity blocks on the surface. The sewage will pass through the separation bar 402 and continue to move downward. And as the separation bar 402 rotates, the impurities located on the surface of the separation bar 402 will be transferred to the interior of the storage cylinder 403 through the dropping groove 418. The falling sewage will contact the first inclined plate 404 and then be transferred to the surface of the second inclined plate 405. At this time, the sewage will move in the direction of the water outlet 424 and be transferred to the interior of the feeding cavity 11 through the water outlet 424. During the transfer of the sewage, since the sizes of the notches on the surface of the second inclined plate 405 increase successively in the direction of the water outlet 424, by installing a plurality of collecting barrels at the lower end of the second inclined plate 405, impurities of different volumes can be classified and collected for subsequent cleaning work. And if some non-filterable suspended solids adhere to the inner wall of the water outlet 424 and accumulate to block the water outlet 424, start the cutting knife 435 to rotate. During the rotation of the cutting knife 435, the blocked solid impurities will be broken up, thus ensuring the smoothness of the water outlet 424. When the sewage enters the interior of the feeding cavity 11, add a coagulant to the feeding cavity 11, and then stir the interior of the feeding cavity 11, so that the wastewater and the coagulant are in full contact. The coagulant can change the hydrophilicity of the suspended particles in the wastewater, causing these suspended particles to flocculate into larger flocs. Then start the bubble pump 32. The bubble pump 32 will generate bubbles in the sewage. These bubbles will adhere to the flocs and rise to the liquid surface to form scum, realizing solid-liquid separation and entering the separation cavity 12. At this time, start the scraper 23. The scraper 23 will scrape the scum above the liquid surface and finally scrape the scum into the waste residue cavity 13, finally completing the sewage treatment. Through the collection structure 4, during the sewage treatment process, the separation bar 402 and the second inclined plate 405 will filter the sewage step by step, ultimately greatly reducing the impurity content of the sewage entering the interior of the feeding cavity 11. And the storage cylinder 403 and the barrels located below the second inclined plate 405 can also classify and collect impurities of different volumes for subsequent cleaning work.

[0024] Such as Figures 1 to 8As shown in the figure, a stirring shaft 16 is rotatably connected inside the feeding cavity 11, and a plurality of stirring blades 15 are arranged on the surface of the stirring shaft 16. The separation structure 2 further includes: a mounting frame 21, which is arranged at the upper end of the base frame 1; a chain 22, which is rotatably connected inside the mounting frame 21, and a plurality of scraping plates 23 are arranged on the surface of the chain 22; the reaction structure 3 further includes: a driving pipe 31, which is arranged at the upper end of the feeding cavity 11, and the driving pipe 31 is used to control the bubble pump 32 to generate bubbles; the collection structure 4 further includes: a driving shaft 415, which is arranged at one end of the separation strip 402; a first crawler 409, which is sleeved at one end of the driving shaft 415; a motor 410, which is arranged on the side wall of the base frame 1, and one end of the first crawler 409 is connected to the motor 410; a trigger frame 428, which is arranged at one end of the feeding frame 401 close to the water outlet 424; a rotating shaft 429, which is arranged inside the trigger frame 428; a floating ball 430, which is rotatably connected to the surface of the rotating shaft 429; a driver 434, which is arranged at one end of the cutting knife 435; a push switch 431, which is arranged at the upper end of the inner wall of the trigger frame 428, and the floating ball 430 contacts the push switch 431 during operation; a connecting line 432, which is arranged at one end of the driver 434, and the other end of the connecting line 432 is communicated with the push switch 431.

[0025] Specifically, when sewage enters the inside of the feeding frame 401, the motor 410 is started. The motor 410 will drive the first crawler 409 to rotate. During the rotation of the first crawler 409, it will drive the separation strip 402 to rotate through the driving shaft 415, so as to separate and collect impurities. When some non-filterable suspended solids adhere to the inner wall of the water outlet 424 and accumulate to block the water outlet 424, since the sewage cannot normally drain from the water outlet 424 at this time, the sewage will gradually move upward and drive the floating ball 430 to move upward. During the movement, the floating ball 430 will abut against the push switch 431. At this time, the push switch 431 will transmit a signal to the driver 434, causing the cutting knife 435 to rotate. When the sewage enters the inside of the feeding cavity 11, the stirring shaft 16 is started. The stirring shaft 16 will drive the stirring blades 15 to stir the sewage. After scum forms on the upper end of the sewage, the chain 22 is started. The chain 22 will drive the scraping plates 23 to move, so as to scrape the scum.

[0026] As Figures 1 to 6As shown in the figure, at one end of the lower surface of the second inclined plate 405 close to the water outlet 424, a third waste frame 408 is provided. At one end of the third waste frame 408 away from the water outlet 424, a second waste frame 407 is provided. At one end of the second waste frame 407 away from the third waste frame 408, a first waste frame 406 is provided. And holes are provided on the small surfaces of the first waste frame 406, the second waste frame 407, and the third waste frame 408.

[0027] Specifically, by providing the first waste frame 406, the second waste frame 407, and the third waste frame 408 on the lower surface of the second inclined plate 405, when the sewage passes through the second inclined plate 405, the three waste frames can collect the filtered impurities, and the holes provided on the lower surface can also discharge the excess sewage, realizing the transfer of the excess sewage.

[0028] As Figures 1 to 6 shown in the figure, a plurality of filter cloths 413 are provided inside the first waste frame 406.

[0029] Specifically, since the volume of the impurities temporarily stored inside the first waste frame 406 may be too small and easily discharged together with the sewage through the holes provided on the lower surface of the first waste frame 406, by providing the filter cloths 413 inside the first waste frame 406, it is possible to avoid the phenomenon that the impurities are transferred together with the sewage during the transfer of the sewage.

[0030] As Figures 1 to 6 shown in the figure, the second inclined plate 405 is slidably connected inside the feeding frame 401, and one end of the second inclined plate 405 extends to the outside of the feeding frame 401. A return spring 423 is provided at one end of the second inclined plate 405 close to the water outlet 424. A toothed plate 411 is provided on the upper surface of the other end of the second inclined plate 405. An intermittent gear 412 is rotatably connected to the outer wall of the feeding frame 401, and the intermittent gear 412 meshes with the toothed plate 411.

[0031] Specifically, by setting the second inclined plate 405 to be slidably connected, when the sewage is transferred to the surface of the second inclined plate 405, the intermittent gear 412 is started to rotate. The intermittent gear 412 will drive the toothed plate 411 to slide. Since the toothed plate 411 is connected to the second inclined plate 405, the second inclined plate 405 will also slide inside the feeding frame 401 at this time. When the intermittent gear 412 no longer meshes with the toothed plate 411, the return spring 423 will release its elastic force, thereby pulling the second inclined plate 405 back to its original position. This cyclic working process will cause the second inclined plate 405 to shake, so that the impurities can enter the first waste frame 406, the second waste frame 407, and the third waste frame 408 more smoothly.

[0032] As Figures 3 to 6As shown, a second crawler belt 414 is sleeved on the surface of the drive shaft 415. A worm 419 is rotatably connected to the outer wall of the feeding frame 401, and the worm 419 meshes with the intermittent gear 412. One end of the second crawler belt 414 is sleeved on the surface of the worm 419.

[0033] Specifically, by setting the second crawler belt 414, when the drive shaft 415 drives the separation bar 402 to rotate, the drive shaft 415 will drive the worm 419 to rotate through the second crawler belt 414. Since the worm 419 meshes with the intermittent gear 412, the intermittent gear 412 will keep rotating at this time, so as to ensure that the second inclined plate 405 can shake continuously.

[0034] Embodiment 2: As Figure 5 shown, compared with Embodiment 1, another implementation manner of the present invention is: a clamping plate 422 is fixedly connected to the side wall of the feeding frame 401, and clamping bars 421 are provided at the upper ends of the first waste frame 406, the second waste frame 407 and the third waste frame 408, and the clamping bars 421 are clamped with the clamping plate 422.

[0035] Specifically, by setting the clamping bars 421, when it is necessary to install the first waste frame 406, the second waste frame 407 and the third waste frame 408, only need to clamp the clamping bars 421 into the inside of the clamping plate 422 to fix them. When removing, only need to pull them out. This fixing method will greatly speed up the subsequent cleaning and installation.

[0036] As Figure 8 shown, a water outlet groove 433 is provided on the inner wall of the trigger frame 428.

[0037] Specifically, by setting the water outlet groove 433, when the inside of the feeding frame 401 is blocked and the water level rises, the water outlet groove 433 can limit the height of the water level, so as to ensure that the water level will not be higher than the pressing switch 431, thus causing damage to the pressing switch 431.

[0038] As Figure 5 shown, an auxiliary baffle 420 is provided on the side wall of the separation bar 402.

[0039] Specifically, by providing the auxiliary baffle 420 on the side wall of the separation bar 402, when the sewage enters the inside of the feeding frame 401 and contacts the separation bar 402, the auxiliary baffle 420 can block some impurities that cannot pass through the separation bar 402 from leaking out from both sides.

[0040] As Figures 1 to 7As shown in the figure, a reciprocating lead screw 416 is provided at one end of the drive shaft 415 close to the storage cylinder 403. A sliding strip 426 is provided at one end of the side wall of the feeding frame 401 close to the reciprocating lead screw 416. A connecting plate 425 is slidably connected to the surface of the sliding strip 426. A pushing piece 427 is provided at the lower end of the connecting plate 425. A connecting block 417 is provided on the right side of the connecting plate 425, and the connecting block 417 is slidably connected to the reciprocating lead screw 416.

[0041] Specifically, by providing a reciprocating lead screw 416 at one end of the drive shaft 415, during the rotation of the drive shaft 415, the drive shaft 415 will drive the reciprocating lead screw 416 to rotate together. Since the connecting block 417 is slidably connected to the reciprocating lead screw 416 and the connecting block 417 slides on the surface of the sliding strip 426, the connecting block 417 can reciprocate on the surface of the reciprocating lead screw 416 at this time, so that the pushing piece 427 connected to the connecting block 417 can gradually push the impurities stored inside the storage cylinder 403 to the outside of the cylinder.

[0042] Working principle: When in use, first pour the sewage into the interior of the feeding frame 401, and then start the motor 410. The motor 410 will drive the first track 409 to rotate. During the rotation of the first track 409, the separation bar 402 will be driven to rotate through the drive shaft 415. During the rotation of the separation bar 402, the notches formed on the surface of the separation bar 402 will temporarily store the larger impurity blocks on the surface. The sewage will pass through the separation bar 402 and continue to move downward. And as the separation bar 402 rotates, the impurities located on the surface of the separation bar 402 will be transferred to the interior of the storage cylinder 403 through the dropping slot 418. The falling sewage will come into contact with the first inclined plate 404 and then be transferred to the surface of the second inclined plate 405. At this time, the sewage will move in the direction of the water outlet 424 and be transferred to the interior of the feeding chamber 11 through the water outlet 424. During the transfer of the sewage, since the sizes of the notches on the surface of the second inclined plate 405 increase successively in the direction of the water outlet 424, by installing multiple collecting barrels at the lower end of the second inclined plate 405, impurities of different volumes can be classified and collected for subsequent cleaning work. And if some non-filterable suspended solids adhere to the inner wall of the water outlet 424 and accumulate to block the water outlet 424, since the sewage cannot normally drain from the water outlet 424 at this time, the sewage will gradually move upward and drive the float ball 430 to move upward. During the movement, the float ball 430 will abut against the pressing switch 431. The pressing switch 431 will then transmit a signal to the driver 434, causing the cutting knife 435 to rotate. When the sewage enters the interior of the feeding chamber 11, start the stirring shaft 16. The stirring shaft 16 will drive the stirring blades 15 to stir the sewage. During the rotation of the cutting knife 435, the blocked solid impurities will be broken up, thus ensuring the smoothness of the water outlet 424. When the sewage enters the interior of the feeding chamber 11, add a coagulant to the feeding chamber 11, and then stir the interior of the feeding chamber 11, so that the wastewater and the coagulant are fully in contact. The coagulant can change the hydrophilicity of the suspended particles in the wastewater, causing these suspended particles to flocculate into larger flocs. Then start the bubble pump 32. The bubble pump 32 will generate bubbles in the sewage. These bubbles will adhere to the flocs and rise to the liquid surface to form scum, realizing solid-liquid separation and entering the interior of the separation chamber 12. At this time, start the scraper 23. The scraper 23 will scrape the scum above the liquid surface and finally scrape the scum into the waste residue chamber 13, finally completing the sewage treatment. Through the collection structure 4, during the sewage treatment process, the separation bar 402 and the second inclined plate 405 will filter the sewage step by step, finally greatly reducing the impurity content of the sewage entering the interior of the feeding chamber 11. And the storage cylinder 403 and the barrels located below the second inclined plate 405 can also classify and collect impurities of different volumes for subsequent cleaning work.
