Description

Technical Field

[0001] This utility model relates to the field of air flotation slag removal technology, specifically an adaptive slag removal air flotation device. Background Technology

[0002] In existing air flotation slag removal devices, when scraping off debris and impurities from the surface of the air flotation tank, the surface of the scraper plate is prone to adhesion of debris and impurities during the scraping process. Since the scraper plate for scraping off air bubbles and debris is rotating in a cycle, it is easy for the debris on the surface of the scraper plate to re-enter the air flotation tank, causing secondary pollution and reducing the effectiveness of air flotation slag removal.

[0003] Therefore, this invention provides an adaptive slag removal air flotation device to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing air flotation slag removal devices are prone to having debris and impurities attached during the scraping process, which can lead to secondary entry into the air flotation tank and cause pollution.

[0005] This utility model provides the following technical solution: an adaptive slag removal flotation device, including a flotation tank and a slag removal structure. The slag removal structure is fixedly installed above the flotation tank. The slag removal structure includes a driving component, a skimmer component, and a slag removal component. The skimmer component is fixedly installed on the surface of the slag removal structure, and the slag removal component is fixedly installed on the surface of the driving component. The driving component drives the skimmer component to skim the skimmer and then contacts the slag removal component, causing elastic displacement to achieve self-cleaning and slag removal.

[0006] In a preferred embodiment of this utility model, the driving assembly includes a base shell, a driving body, a rotating shaft, a connecting body, and a conveyor belt. The base shells are symmetrically fixedly installed on both sides above the flotation tank, and the driving body is fixedly installed on the side of the base shell. At least two rotating shafts in a horizontal array are rotatably installed between the two base shells. A connecting body is installed between adjacent rotating shafts. A conveyor belt is installed on the surface of the rotating shaft, and a skimming assembly is fixedly installed on the surface of the conveyor belt.

[0007] In a preferred embodiment of the present invention, the descaling assembly includes a substrate, a descaling plate, and an elastic element. The substrate is fixedly installed on the surface of the conveyor belt, the descaling plate is slidably installed in the substrate, and an elastic element is slidably placed between the substrate and the descaling plate. Only one end of the elastic element is fixedly connected to the substrate or the descaling plate.

[0008] In a preferred embodiment of this utility model, the shaving plate includes a straight section and an arc section. The straight section is slidably installed in the substrate, the arc section is fixedly installed in the straight section away from the substrate, and the limiting section is fixedly installed in the straight section close to the substrate.

[0009] In a preferred embodiment of this utility model, a float plate is fixedly installed on the slag scraper in the opposite direction of the movement of the transmission belt.

[0010] In a preferred embodiment of the present invention, the slag removal assembly includes a horizontal body, a support, and a rotating wheel. The horizontal body is fixedly installed above the base shell, the support is fixedly installed below the horizontal body, and the rotating wheel is rotatably installed below the support.

[0011] In a preferred embodiment of this utility model, the flotation tank includes a reaction zone, a sludge collection zone, and a drainage zone. The sludge collection zone and the drainage zone are fixedly installed sequentially along the direction of water flow in the reaction zone. A filter screen is installed at an angle in the sludge collection zone, and the bottoms of the sludge collection zone and the drainage zone are interconnected.

[0012] In a preferred embodiment of this invention, the slag collection area is located above the filter screen and a defoamer is fixedly installed thereon.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In the process of the drive component driving the scum scraper to rotate in a cycle, the arc-shaped scum scraper can reduce the bubble rupture caused by local pressure changes during the scraping of debris and impurities on the surface of the flotation tank, which is conducive to improving the integrity of the bubbles and thus improving the scum removal effect. At the same time, during the rotation after scum removal, it will contact the rotating wheel and be squeezed to move towards the substrate and cooperate with the squeezing elastomer, thereby improving the overall longitudinal jumping of the scum scraper, thereby improving the effect of the scum scraper to remove debris and impurities through longitudinal jumping, thus achieving both improved scum removal effect and self-cleaning of the scum scraper.

[0015] 2. In this invention, during the cyclic rotation of the skimmer driven by the drive assembly, the float plate can float on the surface of the flotation tank, thereby fixing the depth and distance at which the skimmer penetrates the wastewater in the flotation tank. Thus, when the wastewater level in the flotation tank changes, the skimmer can adaptively scrape off the debris and impurities on the surface of the flotation tank at a stable distance and depth. Furthermore, the auxiliary scraper fixed vertically below the float plate can move along with the skimmer and scrape off the debris together, which helps to improve the debris removal effect.

[0027] Addressing the technical problem that existing air flotation sludge removal devices easily accumulate debris and impurities during the scraping process, leading to secondary contamination of the air flotation tank, this disclosure provides an adaptive sludge removal air flotation device, such as... Figure 1 As shown, the system includes an air flotation tank 1 and a slag removal structure. The slag removal structure is fixedly installed above the air flotation tank 1. The slag removal structure includes a drive component 2, a skimmer component 3, and a slag removal component 4. The skimmer component 3 is fixedly installed on the surface of the slag removal structure. The slag removal component 4 is fixedly installed above the drive component 2. The drive component 2 drives the skimmer component 3 to skim the foam and then contacts the slag removal component 4, resulting in elastic displacement and self-cleaning slag removal.

[0028] like Figure 1 As shown, the drive assembly 2 includes a base shell 21, a drive body 22, a rotating shaft 23, a connecting body 24, and a conveyor belt 25. The base shells 21 are symmetrically fixedly installed on both sides above the flotation tank 1. The drive body 22 is fixedly installed on the side of the base shells 21. At least two rotating shafts 23 in a horizontal array are rotatably installed between the two base shells 21. The connecting body 24 is installed between adjacent rotating shafts 23. The conveyor belt 25 is installed on the surface of the rotating shaft 23. The skimmer assembly 3 is fixedly installed on the surface of the conveyor belt 25.

[0029] like Figure 1 As shown, it should be noted that the driving body 22 is coaxially fixed with any one of the rotating shafts 23 for driving, so that all the rotating shafts 23 can rotate synchronously and in the same direction through the connecting body 24.

[0030] It should be noted that the drive body 22 in this embodiment adopts a motor in the prior art. The extremely mature motor technology will not be described in detail here. In addition, any other structure or device that can drive the rotating shaft 23 to rotate can also be adopted.

[0031] It should be noted that the connecting body 24 can be any structure or device in the prior art that can make adjacent rotating shafts 23 rotate synchronously and in the same direction, such as chains, belts, or gears. In this embodiment, the connecting body 24 uses a belt and pulleys. The pulleys are fixedly installed at the ends of the rotating shafts 23, and the belts cause all the pulleys and rotating shafts 23 to rotate synchronously, thereby driving the conveyor belt 25 to work.

[0032] like Figure 1 As shown, the conveyor belt 25 has a ring structure and rotates cyclically around the rotating shaft 23.

[0033] When removing sludge from the flotation tank 1, the operator first starts the drive body 22, which drives the rotating shaft 23 to rotate. This causes at least two rotating shafts 23 in the horizontal array to rotate synchronously through the connecting body 24, thereby driving the conveyor belt 25 and the skimmer assembly 3 to work along the direction of water flow. This allows the skimmer assembly 3 on the surface of the conveyor belt 25 to move and scrape off the bubbles and debris on the surface of the flotation tank 1. After the film attachment assembly removes the sludge, it comes into contact with the impurity removal assembly for self-cleaning.

[0034] like Figure 2 and 3 As shown, the slag removal assembly 3 includes a base 31, a slag removal plate 32, and an elastic element 33. The base 31 is fixedly installed on the surface of the conveyor belt 25. A groove 311 is formed in the base 31. The slag removal plate 32 is slidably installed in the groove 311. An elastic element 33 is slidably placed between the base 31 and the slag removal plate 32. Only one end of the elastic element 33 is fixedly connected to the base 31 or the slag removal plate 32.

[0035] like Figure 2 and 3 As shown in the embodiments of this disclosure, the elastomer is a spring. In addition, any other structure or device capable of deformation to provide elasticity can be used, such as an airbag.

[0036] During the rotation of the conveyor belt 25, when the substrate 31 and the skimmer 32 move on the lower surface of the conveyor belt 25, they scrape off the bubbles and debris on the surface of the flotation tank 1. When the substrate 31 and the skimmer 32 are on the upper surface of the conveyor belt 25, they return to the lower surface for the next cycle to scrape off the bubbles and remove the debris.

[0037] like Figure 1As shown, the substrate 31 and the skimmer 32 rotate in a cycle following the conveyor belt 25, thereby continuously scraping off the bubbles and debris on the surface of the flotation tank 1.

[0038] like Figure 2 and 3 As shown, during the process of scraping and removing slag by the skimmer 32 located below the conveyor belt 25, the skimmer 32 is located in the substrate 31 and slides in the chute 311 in a direction away from the substrate 31, that is, it moves downward due to its own weight. During the downward sliding process of the skimmer 32 located below the conveyor belt 25, the skimmer 32 can fully extend to scrape and remove slag and impurities from the surface of the flotation tank 1.

[0039] like Figure 2 and 3 As shown, it should be noted that after the scraper plate 32 slides downwards below the conveyor belt 25, the length of the space inside the groove 311 is greater than that of the elastic body. Furthermore, if one end of the elastic body is fixedly connected to the inner side of the groove 311 of the base 31, the elastic body remains stationary; if one end of the elastic body is fixedly connected to the surface of the scraper plate 32, the elastic body slides synchronously with the scraper plate 32.

[0040] After the skimmer 32 scrapes off the bubbles and debris on the surface of the flotation tank 1, the skimmer 32 moves to the upper side with the rotation of the conveyor belt 25. During the process of the skimmer 32 moving to the upper side, the skimmer 32 slides towards the substrate 31 due to its own weight. When the skimmer 32 slides towards the substrate 31, the elastic body is squeezed and longitudinally jumps. The longitudinal jumping of the skimmer causes the debris attached to the surface of the skimmer 32 to fall off, thereby cleaning the impurities attached to the surface of the skimmer 32.

[0041] Example 2: Based on Example 1 above, only the differences are described below, and the similarities will not be repeated.

[0042] In this embodiment, water quality monitoring instruments, such as suspended solids concentration sensors, turbidity meters, and flow sensors, are installed at the inlet and outlet of the flotation tank 1 to monitor water quality and flow rate changes in real time. For example, parameters such as the concentration, size distribution, and flow rate of suspended particles in the water are measured and transmitted to the control system. The system then compares and analyzes the water quality against preset standards using existing control mechanisms. When water quality parameters deviate from the set values, the operating parameters of relevant equipment are automatically adjusted, such as the dosage of coagulants and flocculants, and the flow rate and pressure of dissolved air water. When the influent flow rate increases, the pump speed is increased to increase the dissolved air water flow rate, allowing more air bubbles to contact suspended particles, while appropriately extending the residence time of wastewater in the flotation tank 1 to ensure solid-liquid separation. Conversely, when the influent flow rate decreases, the pump speed is reduced to decrease the dissolved air water flow rate, avoiding energy waste and excessive equipment operation. This allows the system to adapt to changes in water quality and flow rate, achieving adaptive sludge removal and ensuring stable sludge removal performance. It should be noted that the structure and equipment for achieving adaptive sludge removal are existing technologies and will not be elaborated upon here.

[0043] like Figure 2 and 3 As shown, the slag scraper 32 includes a straight section 321 and an arc section 322. The straight section 321 is slidably installed inside the base 31. An arc section is fixedly installed on the straight section 321 away from the base 31. A limiting section is fixedly installed on the straight section 321 close to the base 31.

[0044] During the process of the scraper plate 32 following the conveyor belt 25 in a cyclical rotation to clean the debris and impurities on the surface of the flotation tank 1, the straight section 321 slides within the chute 311, and the limiting part ensures that the straight section 321 does not detach from the chute 311 during the sliding process. When the arc section 322 extends outward from the straight section 321 within the chute 311, that is, when it slides away from the substrate 31, the arc section 322 contacts and scrapes away the debris and impurities on the surface of the flotation tank 1 to achieve slag removal.

[0045] The arc section 322 of the arc structure gradually transitions when it comes into contact with the bubble. The curvature causes the contact point to change continuously, and the force on the bubble is more dispersed. It will not generate excessive stress at a certain point or in a certain area, reducing the bubble rupture caused by sudden changes in local pressure, which is conducive to improving the effect of scraping bubbles for deslagging.

[0046] like Figure 2 and 3As shown, a float plate 34 is fixedly installed on the scraper plate 32 in the opposite direction of the transmission belt movement. When the straight portion 321 of the scraper plate 32 slides away from the substrate 31 in the chute 311, the float plate 34 can float on the surface of the flotation tank 1, thereby fixing the depth and distance at which the scraper plate 32 penetrates the sewage in the flotation tank 1. Thus, when the sewage level in the flotation tank 1 changes, the scraper plate 32 can adaptively scrape and remove debris and impurities from the surface of the flotation tank 1 at a stable distance and depth.

[0047] like Figure 1 As shown, the slag removal assembly 4 includes a horizontal body 41, a support 42, and a rotating wheel 43. The horizontal body 41 is fixedly installed above the base shell 21, the support 42 is fixedly installed below the horizontal body 41, and the rotating wheel 43 is rotatably installed below the support 42.

[0048] After the scraper plate 32 scrapes and removes the slag and impurities in the flotation tank 1, the scraper plate 32 rotates with the conveyor belt 25 to the top of the conveyor belt 25. When the scraper plate 32 is above the conveyor belt 25, it will contact the rotating wheel 43 and be squeezed, thereby causing the scraper plate 32 to move towards the substrate 31 and cooperate with the squeezing elastomer, thereby improving the overall longitudinal jumping of the scraper plate 32, and thus improving the effect of the scraper plate 32 in removing slag and impurities through longitudinal jumping.

[0049] The rotating wheel 43 can rotate in the support 42, thereby reducing frictional resistance when squeezing the slag scraper 32.

[0050] like Figure 2 and 3 As shown, an auxiliary scraper 341 is vertically fixed below the float plate 34. Through the auxiliary scraper 341, the distance and depth at which the skimmer 32 penetrates the wastewater in the flotation tank 1 are adaptively fixed by the float plate 34. While the skimmer 32 moves to scrape and remove debris and impurities from the surface of the flotation tank 1, the auxiliary scraper 341 moves synchronously with the skimmer 32 to scrape and remove debris and impurities from the flotation tank 1, thus improving the scraping and removal effect of debris and impurities in the flotation tank 1 while adaptively controlling the distance and depth of penetration into the wastewater.

[0051] like Figure 2 and 3 As shown, the auxiliary scraper 341 has an arc-shaped structure. The arc-shaped auxiliary scraper 341 gradually transitions into contact with the air bubbles, reducing horizontal shear force and preventing excessive stress at any point or in any area. This reduces the risk of air bubble rupture caused by sudden changes in local pressure, thereby improving the effect of removing air bubbles and slag.

[0052] It should be noted that the rotating wheel 43 can sequentially squeeze the arc portion 322 of the slag scraper 32 and the auxiliary scraper 341. When squeezing the slag scraper 32 and the auxiliary scraper 341, the slag scraper 32 will squeeze the elastic body and vibrate, thereby further improving the cleaning effect on the surface of the slag scraper 32.

[0053] When removing debris and impurities from the inner surface of the flotation tank 1, the operator first starts the drive body 22, which drives any one of the rotating shafts 23 to rotate. At least two rotating shafts 23 in the horizontal array rotate synchronously through the connecting body 24, thereby driving the conveyor belt 25 and the skimmer 32 to work along the direction of water flow.

[0054] When the skimmer 32 moves below the conveyor belt 25, the skimmer 32 is located in the substrate 31 and slides in the chute 311 in a direction away from the substrate 31, so that the skimmer 32 can be fully extended and move with the conveyor belt 25 to scrape off the bubbles and debris on the surface of the flotation tank 1.

[0055] During the process of the scraper plate 32 fully extending and moving to scrape and remove sludge, the float plate 34 can float on the surface of the flotation tank 1, thereby fixing the depth and distance at which the scraper plate 32 penetrates the sewage in the flotation tank 1. This allows the scraper plate 32 to adaptively scrape and remove debris and impurities from the surface of the flotation tank 1 at a stable distance and depth, even when the sewage level changes. Furthermore, the auxiliary scraper plate 341, vertically fixed below the float plate 34, can move along with the scraper plate 32 and scrape and remove sludge together, which helps improve the sludge removal effect.

[0056] After the scraper blade 32 removes slag, it moves along the conveyor belt 25 to above it. There, it contacts and is compressed by the rotating wheel 43, causing it to move closer to the substrate 31 and cooperate with the compression elastomer. This increases the overall longitudinal movement of the scraper blade 32, thereby improving its ability to remove debris and impurities through longitudinal movement. Furthermore, after the arc portion 322 of the scraper blade 32 contacts and compresses the rotating wheel 43 to clean the attached impurities, the auxiliary scraper blade 341 can again contact the rotating wheel 43 and cause the scraper blade 32 to vibrate, further improving the cleaning effect on the surface of the scraper blade 32.

[0057] Example 3: Based on Examples 1 and 2 above, only the differences will be described below, and the similarities will not be repeated.

[0058] like Figure 4 and 5 As shown, a horizontal body 41 is fixedly installed on the base shell 21 in the horizontal direction, a bracket 42 is fixedly installed on the horizontal body 41 in the horizontal direction, and a rotating wheel 43 is rotatably installed on the bracket 42 in the horizontal direction.

[0059] During the cleaning and slag removal process of the scraper plate 32, when the scraper plate 32 moves to a horizontal position, it contacts the horizontal support 42 and the rotating wheel 43, thereby causing the straight section 321 to slide horizontally in the slide groove 311 and squeeze the elastic element 33. Thus, by sliding horizontally without overcoming its own weight, the vibration of the straight section 321 in the slide groove 311 is further improved, thereby improving the slag removal effect of the scraper plate 32.

[0060] like Figure 5 As shown, it should be noted that in this embodiment, the entire slag removal assembly 4 is not located inside the flotation tank 1. Therefore, during the slag removal process when the scraper plate 32 is in a horizontal state, the slag and impurities will not fall onto the surface of the conveyor belt 25, thus avoiding secondary adsorption of slag and impurities on the surface of the conveyor belt 25, which would cause backflow into the flotation tank 1 and cause pollution.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
