Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an industrial wastewater treatment device with water quality detection function. Background Technology

[0002] Dissolved air flotation (DAF) is a process used in industrial wastewater treatment to achieve solid-liquid separation. Its basic principle is to introduce a large number of highly dispersed microbubbles into the wastewater, causing them to adhere to the surface of hydrophobic pollutant particles, forming a particle complex with an overall density less than water. These particles then rapidly rise to the surface under buoyancy and are removed by a scraper, thus separating the pollutants. Existing DAF machines, such as the dissolved air flotation machine disclosed in patent announcement number CN220502729U, include a treatment tank. The interior of the treatment tank, from front to back, comprises a reaction tank, a flotation tank, a separation tank, and a filter. The reaction tank has symmetrically installed stirring devices at the top and near both sides. Between the two stirring devices and inside the reaction tank, there is a wastewater auxiliary mixing treatment mechanism. Each of the two stirring devices has a coagulant filling channel on the side near the flotation tank. Multiple sets of wastewater through holes make the wastewater discharge more uniform. In conjunction with the discharge holes that are equally spaced from top to bottom on the coagulant filling channel, the flocculant and coagulant aid pipes are discharged respectively. Under the operation of the stirring devices, a space with good mixing effect between wastewater and coagulant is formed in the reaction tank, which improves the solid-liquid separation stability of the flotation tank.

[0003] In existing air flotation equipment, the wastewater to be treated is first introduced into the reaction zone and mixed with added flocculants (such as PAC) and coagulants (such as PAM) to react. Then, the wastewater enters the contact zone, where microbubbles combine with flocs to form scum. This scum is then skimmed off by a mechanical scraper and discharged to the sludge collection zone. The lower clarified water overflows into the clear water zone. Currently, commonly used scraping devices mainly include core components such as a drive motor, drive shaft, pulley, drive belt, and scraper blades, similar to the scraping structures in the aforementioned existing technologies. The scraper blades need to continuously reciprocate to complete the skimming process. In slag scraping operations, however, after a single scraping action, when the scraper returns to the upper area, some of the particles adhering to its surface fall onto the drive belt. During continuous operation, the belt continuously transports these particles to the pulley area. Since the structure of commonly used pulleys is usually designed with high flanges on both sides and a groove in the middle of the wheel surface, the drive belt runs precisely within this groove. When the fallen particles accumulate in the contact area between the belt and the pulley for a long time and reach a certain amount, the belt may come off the preset groove track, leading to transmission failure and ultimately interrupting the normal operation of the entire slag scraping process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an industrial wastewater treatment device with water quality detection capabilities, aiming to improve the long-term operational reliability and self-maintenance capability of the sludge scraping assembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an industrial wastewater treatment device with water quality detection function, comprising a flotation unit body, a water quality analyzer installed inside the flotation unit body, and a scraper assembly installed on the flotation unit body. The scraper assembly includes a conveyor belt and a scraper plate fixedly installed on the conveyor belt.

Cylindrical scrapers are rotatably mounted on both the mounting plate and the mounting housing on the side of the conveyor belt. A rotating shaft is fixedly installed on each of the cylindrical scraper blades. The outer ends of the two rotating shafts pass through the mounting plate and the mounting housing, respectively, and a cross-shaped push plate is fixedly installed on them.

A cleaning assembly for cleaning the cylindrical scraper blade is rotatably installed at the lower end of the mounting housing. A rotating assembly for controlling the vibration of the cleaning assembly is rotatably installed inside the mounting housing. Connecting blocks for pushing the rotating assembly are also fixedly installed on both sides of the scraper blade. The connecting blocks are fixed to the conveyor belt. A suction assembly for cleaning the cleaning assembly is rotatably installed inside the mounting housing.

[0006] Preferably, the slag scraping assembly further includes two conveying rods rotatably mounted on the main body of the flotation machine, each of the two conveying rods being fixedly fitted with two pulleys, the conveying belt being fitted onto the pulleys, and a motor for controlling the rotation of the conveying rods being fixedly mounted on the main body of the flotation machine.

[0007] Preferably, the mounting bracket includes a fixed rod fixedly mounted on the air flotation machine body, and two connecting rods are fixedly sleeved on the fixed rod, with both ends of the connecting rods being fixedly connected to the mounting bracket.

[0008] Preferably, the cleaning assembly includes a rotating rod rotatably connected to the mounting housing, with an arc-shaped scraper sleeved at the lower end of the rotating rod, and the rotating rod is rotatably connected to the upper wall of the mounting housing via a torsion spring.

[0009] Preferably, the rotating assembly includes a rotating column rotatably connected to the mounting housing. The rotating column is rotatably connected to the side wall of the mounting housing via a torsion spring. A fixing block is fixedly installed at one end of the rotating column outside the mounting housing. A semi-ring is fixedly sleeved on the rotating column. Multiple hemispheres are fixedly installed on one side of the semi-ring. A push block is fixedly installed on one side of the rotating rod. The vertical distance between two adjacent hemispheres is greater than the thickness of the push block.

[0010] Preferably, the suction assembly includes a tripod fixedly mounted on a rotating rod, with rollers rotatably mounted on the outer ends of the tripod. A circular shell is fixedly mounted inside the mounting housing, and the circular shell is fitted onto the outside of the tripod. A flexible tube is placed on the inner wall of the circular shell, and the rollers and the flexible tube are in compression contact. A rigid tube is fixedly connected to the outside of the air flotation machine body, and one end of the rigid tube is connected to the flexible tube. A connector is mounted on the rotating rod, and the other end of the flexible tube is connected to the connector.

[0011] Preferably, the connector includes a circular cavity fixedly installed at the bottom of the mounting housing, the rotating rod is rotatably connected to the circular cavity, the rotating rod has a cavity inside, and the rotating rod has multiple through holes communicating with the cavity on its outer side. Some of the through holes communicate with the circular cavity, and some of the through holes are located above the arc-shaped scraper and below the mounting housing. The flexible hose is fixedly connected to the circular cavity.

[0012] Preferably, there is a gap between the first push plate and the second push plate and the corresponding cylindrical scraper.

[0013] Preferably, a toothed ring is fixedly fitted on the motor output end and one of the transmission rods, and a toothed belt is fitted between the two toothed rings.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention involves rotating cylindrical scrapers on both the mounting plate and the mounting housing on one side of the conveyor belt. The two cylindrical scrapers slide in contact with the upper and lower sides of the conveyor belt, respectively. Their function is to continuously scrape away fixed particles and other impurities from the surface of the conveyor belt. Due to the geometric characteristics of the cylindrical scrapers, the scraping surface is arc-shaped. Some of the scraped impurities fall onto the floating scum below, while some adhere to the cylindrical scraper. When the scraper passes one side of the cylindrical scraper, the first and second push plates on the scraper push the corresponding cross-shaped push plates to rotate. This rotation process achieves two key technical objectives: firstly, it allows the cylindrical scraper to rotate around its axis, updating different arc-shaped surfaces for subsequent scraping to maintain an effective scraping surface; secondly, while switching arc-shaped surfaces, the coordinated action of the linked cleaning components automatically cleans the floating scum adhering to the surface of the cylindrical scraper, thereby ensuring the continuous and effective operation of the self-cleaning device and reducing the occurrence of conveyor belt detachment or deviation due to particle accumulation.

[0015] 2. In this invention, when the scraper plate moves to the side of the cylindrical scraper plate and pushes the corresponding cross-shaped pusher plate to complete the rotation, the connecting block on the side of the scraper plate will push the fixed block to rotate. The fixed block is linked with the rotating column, thereby driving the rotating column to rotate. During the rotation of the rotating column, multiple hemispheres will periodically push the pusher block on the rotating rod, causing the pusher block to move back and forth. This displacement is converted into the repeated oscillation of the arc-shaped scraper through the rotating rod, shaking the scraped particles onto the scum below.

[0016] 3. In this invention, during the rotation of the cross-shaped pusher plate, the tripod structure is driven to rotate synchronously. The rotational motion of the tripod is converted into the displacement of the roller, thereby periodically squeezing a flexible tube. This squeezing action constitutes a peristaltic pumping mechanism, which can draw clean water from the main body of the air flotation machine into the circular cavity through the rigid pipe and flexible tube. Subsequently, the water flow is guided to the outer surface of the arc-shaped scraper through the cavity and perforation connected to the circular cavity, thereby achieving auxiliary rinsing of the working surface of the arc-shaped scraper. The key to this design is the linkage between its action and the main slag circulation. The above-mentioned suction and rinsing process is triggered only once when the scraper plate completes a complete reciprocating cycle. The water volume pumped each time is small. This intermittent, low-flow rinsing method can effectively clean the scraper while minimizing the disturbance of the separated slag layer below due to the impact of large water volume, preventing the slag from re-settling or breaking, thereby ensuring the stability of the overall air flotation separation process.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] Please see Figures 1-8An industrial wastewater treatment device with water quality testing function includes a flotation unit body 1 (including a reaction zone I, a contact zone II, a clear water zone III, and a sludge collection zone IV), a water quality analyzer 32 installed inside the flotation unit body 1 (the water quality analyzer 32 is installed in the clear water zone III for testing the water quality in the clear water zone III, and for cooperating with other equipment to provide feedback on the test results; this equipment and testing process are existing technologies and will not be described in detail here), and a sludge scraping assembly installed on the flotation unit body 1. The sludge scraping assembly includes a conveyor belt 3 and a scraper plate 6 fixedly installed on the conveyor belt 3 (the scraper plate 6 operates slowly during operation). A mounting frame is fixedly installed on the flotation unit body 1. Multiple mounting brackets 11 are fixedly installed on the mounting frame. The slag scraping assembly also includes two conveying rods 8 rotatably mounted on the main body 1 of the flotation machine. Two pulleys 7 are fixedly fitted on each of the two conveying rods 8, and a conveying belt 3 is fitted on the pulleys 7. A motor 2 for controlling the rotation of the conveying rods 8 is fixedly installed on the main body 1 of the flotation machine (a toothed ring is fixedly fitted on the output end of the motor 2 and on one of the conveying rods 8, and a toothed belt is fitted between the two toothed rings). The mounting frame includes a fixing rod 4 fixedly mounted on the main body 1 of the flotation machine. Two connecting rods 9 are fixedly fitted on the fixing rod 4, and the two ends of the connecting rods 9 are fixedly connected to the mounting brackets 11 respectively (the two ends of the connecting rods 9 are located on one side of the pulleys 7 respectively). Mounting bracket 1 A mounting plate 19 and a mounting housing 15 are fixedly installed on one side of the conveyor belt 3. Cylindrical scrapers 10 are rotatably mounted on both the mounting plate 19 and the mounting housing 15 on one side of the conveyor belt 3. Rotating shafts 16 are fixedly mounted on both cylindrical scrapers 10. The outer ends of the two rotating shafts 16 pass through the mounting plate 19 and the mounting housing 15 respectively, and cross-shaped push plates 17 are fixedly mounted on them. A first push plate 14 and a second push plate 12 for pushing the cross-shaped push plates 17 to rotate are fixedly mounted on both sides of the scraper 6. A cleaning assembly for cleaning the cylindrical scrapers 10 is rotatably mounted on the lower end of the mounting housing 15. The two cylindrical scrapers 10 slide in contact with the upper and lower sides of the conveyor belt 3 respectively, their function being to continuously scrape the surface of the conveyor belt 3. Fixed particles and other impurities on the surface, due to the geometric characteristics of the cylindrical scraper 10, the scraping surface is an arc-shaped surface. Some of the scraped impurities will fall onto the floating slag below, and some will stick to the cylindrical scraper 10. When the scraper 6 passes one side of the cylindrical scraper 10, the first push plate 14 and the second push plate 12 on the scraper 6 will push the corresponding cross-shaped push plate 17 to rotate (there are gaps between the first push plate 14 and the second push plate 12 and the corresponding cylindrical scraper 10 to avoid interference with the cylindrical scraper 10). This rotation process achieves two key technical objectives: first, to make the cylindrical scraper 10 rotate around its axis, update different arc-shaped surfaces for subsequent scraping, so as to always maintain an effective scraping surface;Secondly, while switching the arc-shaped surface, the cleaning components linked to it can automatically clean the scum adhering to the surface of the cylindrical scraper 10, thereby ensuring the continuous and effective operation of the self-cleaning device. A rotating assembly for controlling the vibration of the cleaning component is rotatably installed inside the mounting housing 15. Connecting blocks 13 for pushing the rotating assembly are fixedly installed on both sides of the scraper 6. The connecting blocks 13 are fixed to the conveyor belt 3. The cleaning component includes a rotating rod 28 rotatably connected to the mounting housing 15. An arc-shaped scraper 18 is sleeved at the lower end of the rotating rod 28. The rotating rod 28 is rotatably connected to the upper wall of the mounting housing 15 via a torsion spring. While switching the arc-shaped surface of the cylindrical scraper 10, the scraper 18 automatically cleans the floating debris adhering to the surface of the cylindrical scraper 10, thereby ensuring the continuous and effective operation of the self-cleaning device. The rotating assembly includes a rotating column 21 rotatably connected to the mounting housing 15. The rotating column 21 is rotatably connected to the side wall of the mounting housing 15 via a torsion spring. A fixing block 22 is fixedly installed at one end of the rotating column 21 outside the mounting housing 15. A semi-ring 24 is fixedly sleeved on the column 21. Multiple hemispheres 29 are fixedly installed on one side of the semi-ring 24. A push block 30 is fixedly installed on one side of the rotating rod 28. The vertical distance between two adjacent hemispheres 29 is greater than the thickness of the push block 30. When the scraper 6 moves to the side of the cylindrical scraper 10 and pushes the corresponding cross-shaped push plate 17 to complete the rotation, the connecting block 13 on the side of the scraper 6 will push the fixed block 22 to rotate. The fixed block 22 is linked with the rotating column 21, thereby driving the rotating column 21 to rotate. During the rotation of the rotating column 21, multiple hemispheres 29 will periodically push the push block 30 on the rotating rod 28, causing the push block 30 to move back and forth. This displacement is converted into the repeated oscillation of the arc-shaped scraper 18 through the rotating rod 28, shaking the scraped particles onto the scum below. A suction component for cleaning the cleaning component is rotatably installed inside the housing 15.

[0021] As a further technical solution of the present invention, the suction assembly includes a tripod 26 fixedly sleeved on a rotating rod 28. Rollers 27 are rotatably mounted on the outer ends of the tripod 26. A circular shell 23 is fixedly installed inside the mounting housing 15. The circular shell 23 is sleeved on the outside of the tripod 26. A flexible tube 20 is placed on the inner wall of the circular shell 23. The rollers 27 and the flexible tube 20 are in compression contact. A rigid tube 5 is fixedly connected to the outside of the air flotation machine body 1. The rigid tube 5 is connected to one end of the flexible tube 20. A connector is sleeved on the rotating rod 28. The other end of the flexible tube 20 is connected to the connector. The connector includes a circular cavity 25 fixedly installed at the bottom of the mounting housing 15. The rotating rod 28 is rotatably connected to the circular cavity 25. A cavity is opened inside the rotating rod 28. Multiple through holes 31 communicating with the cavity are opened on the outside of the rotating rod 28. Some of the through holes 31 are connected to the circular cavity 25. Some of the through holes 31 are located above the arc-shaped scraper 18 and below the mounting housing 15. The flexible tube 20 is fixedly connected to the circular cavity 25. During the rotation of the push plate 17, the tripod 26 is driven to rotate synchronously. The rotational motion of the tripod 26 is converted into the displacement of the roller 27, which periodically squeezes the hose 20. This squeezing action constitutes a peristaltic pumping mechanism, which can draw clean water in the main body 1 of the air flotation machine through the hard pipe 5 and the hose 20 into the circular cavity 25. Subsequently, the water flow is guided to the outer surface of the arc-shaped scraper 18 through the cavity and perforation 31 connected to the circular cavity 25, thereby achieving auxiliary rinsing of the working surface of the arc-shaped scraper 18. The key to this design is the linkage between its action and the main slag circulation. The above-mentioned suction and rinsing process is triggered only once when the scraper plate 6 completes a complete reciprocating cycle. The amount of water pumped each time is small. This intermittent, low-flow rinsing method can effectively clean the scraper while minimizing the disturbance of the separated slag layer below due to the impact of large water volume, preventing the slag from settling or breaking again, thereby ensuring the stability of the overall air flotation separation process.

[0022] When using: Wastewater is first pumped to reaction zone I, and flocculant PAC and coagulant aid PAM are injected into reaction zone I. After flocculation reaction, raw water enters contact zone II. In contact zone II, microbubbles in dissolved air water attach to the flocculated suspended solids. The overall density of the suspended solids with a large number of microbubbles attached is less than one. Then the flocs and bubbles rise to the liquid surface together to form scum, thus achieving solid-liquid separation. The scum is scraped to sludge zone IV by scraper plate 6. The clear water in the lower layer flows by gravity to clear water zone III through water collection pipe. Water quality detector 32 installed in clear water zone (III) continuously monitors the quality of the treated effluent online. During the sludge scraping process, the motor 2 is turned on to drive the conveyor rod 8 and the pulley 7 to rotate, which in turn drives the conveyor belt 3 to circulate. The sludge scraper 6, which is fixedly installed on the conveyor belt 3, moves accordingly, scraping the sludge on the surface of the liquid in the contact area II of the air flotation machine body 1 towards the sludge collection area IV. When the scraper blade 6 runs to the return section of the conveyor belt 3 near the side of the mounting plate 19 and the mounting housing 15, the following self-cleaning process is triggered: 1. Cleaning the conveyor belt 3: The two cylindrical scrapers 10 on the mounting plate 19 and the mounting housing 15 continuously slide in contact with the upper and lower working surfaces of the conveyor belt 3 to scrape off the particulate impurities adhering to the belt.

[0023] 2. Update the working surface of the scraper: The first push plate 14 and the second push plate 12 on the side of the scraper 6 respectively push the corresponding cross-shaped push plate 17 to rotate. The cross-shaped push plate 17 drives the rotating shaft 16 and the cylindrical scraper 10 to rotate at a certain angle, so that the new arc-shaped surface of the cylindrical scraper 10 without impurities is turned into the working position, realizing self-renewal. 3. Cleaning the cylindrical scraper 10: After pushing the cross-shaped pusher 17 to rotate, the connecting block 13 of the scraper 6 pushes the fixing block 22. The fixing block 22 drives the rotating column 21 to rotate and the torsion spring resets. The hemisphere 29 on the rotating column 21 periodically pushes the pusher 30. The reciprocating motion of the pusher 30 is converted into the repeated swinging of the arc scraper 18 through the rotating rod 28, and the repeated knocking of the cylindrical scraper 10 and the torsion spring resets, shaking the particles adhering to it to the scum area below. 4. Flushing and cleaning tools: The rotation of the cross-shaped push plate 17 simultaneously drives the rotating rod 28 and its tripod 26 to rotate. The roller 27 on the tripod 26 squeezes the hose 20 during rotation, forming a peristaltic pump effect, which draws the clean water in the clear water zone III of the air flotation machine through the hard pipe 5 and the hose 20 to the circular cavity 25. The clean water enters the cavity of the rotating rod 28 from the circular cavity 25 and then flows out through the perforation 31, which performs a small-flow, low-impact flushing of the surface of the arc-shaped scraper 18 to prevent the scum layer from being disturbed. By utilizing the cyclical motion of the scraper 6 itself as the power source to trigger all subsequent cleaning actions, the first push plate 14, the second push plate 12, the cross-shaped push plate 17, the rotating column 21, the hemisphere 29, the push block 30 and other components are linked together to realize the automatic renewal of the working surface of the cylindrical scraper 10, the mechanical shaking off the particles attached to its surface, and the intermittent small-flow water flushing of the arc-shaped scraper 18. This reduces the occurrence of faults such as the conveyor belt 3 falling off or running off track due to particle accumulation, and thus extends the maintenance interval.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will readily make equivalent substitutions for its features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
