Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to a high-efficiency sludge oil-water separation and treatment device. Background Technology

[0002] Urban wastewater treatment plants, industrial wastewater treatment stations, and some livestock wastewater treatment systems generate large amounts of excess sludge during operation. Traditional sludge treatment processes often involve overall mixing, with typical steps including thickening, dewatering, anaerobic digestion, drying, incineration, and landfill. In recent years, to improve sludge resource utilization efficiency and reduce energy consumption and treatment costs, sludge is typically treated by separation. Sludge is collected and treated according to its source (e.g., primary sludge, excess sludge, chemical sludge) or properties (e.g., moisture content, organic matter content, heavy metal content), thereby achieving precise control, differentiated utilization, and efficient treatment. Through separation, high-organic-matter sludge enters the anaerobic digestion system, increasing gas production; while low-organic-matter or high-inorganic-matter sludge can be used for brick making, building material fillers, etc.

[0003] A search revealed that utility model patent CN222700181U discloses an impurity separation device for industrial sludge treatment. Through connecting components and filtering components, the device can be effectively protected and its service life extended. When the device needs cleaning or replacement of parts, it can be operated quickly and conveniently, thereby reducing downtime and improving overall maintenance efficiency.

[0004] In traditional sludge separation systems, oil-water separation usually relies on buoyancy and natural stratification. However, the oil and water layers may not be completely separated, resulting in unclear oil-water separation and oil-water mixing. In addition, the introduction of water into the scum and oil layer also affects the oil-water separation effect. Summary of the Invention

A grid is fixedly connected to one side surface of a fitted circular plate; Another grid is fixedly connected to one side surface of the fitting circular plate.

[0010] A further technical improvement of the present invention is that: the inner cavity of the water inlet channel is provided with a limiting groove below the first and second grids, and a waste box is slidably provided inside the limiting groove along the track direction; The processing box is equipped with an actuator cylinder that drives the waste box to move; The limiting groove cavity is equipped with a sealing unit to limit the movement of the waste bin.

[0011] A further technical improvement of the present invention is that: the sealing unit includes a side plate, and a reference plate is fixed on each of the four edge surfaces of the side plate. An expansion member is connected to the surface of each reference plate, and a pushing member that slides along the side plate is connected to the expansion end of each expansion member. The distance between two adjacent reference plates at the same height matches the length of the waste bin; The bottom surface of the inner cavity of the waste bin is equipped with a grid plate.

[0012] A further technical improvement of the present invention is that: the upper surface of the processing box is provided with a sludge scraping chamber for scraping off the sludge on both sides of the blockage plate; A fixing post is fixedly provided on the bottom surface of the inner cavity at the connection between the two processing cavities, and a slot is provided in the middle of the bottom surface of the blocking plate; The slot fits into the surface of the fixed column, and the blocking plate contacts the inner wall of the connection between the two processing cavities through a sealing gasket.

[0013] A further technical improvement of the present invention is that: the end of the main shaft extends into another processing cavity, and a sieve plate is installed on the outer surface of the main shaft, and sieves with different apertures are respectively provided on both sides of the interior of the other processing cavity.

[0014] A further technical improvement of the present invention is that: the outer surface of one processing chamber is provided with a cleaning hole plate that is pushed by a transverse cylinder and slidably limited to another processing chamber, and two cleaning hole plates are provided; The airflow ejected from the cleaning plate acts on the screen holes that are clogged.

[0015] A further technical improvement of the present invention is that: both sides of the processing box are provided with discharge channels, and each discharge channel is slidably installed with a mud collection box for collecting mud of the corresponding aperture. The two mud collection boxes are moved closer or further apart by a two-way screw and a guide rail on the discharge channel.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up an oil-pushing plate, contact components, and a transition ramp, initially, the water inlet channel accurately aligns with the opening on the top surface of the treatment tank, facilitating the passage of sludge fluid. Dissolved air in the return water is introduced through a multi-hole nozzle, releasing microbubbles. These microbubbles adhere to the surface of oil droplets and suspended particles, forming gas-solid aggregates that quickly float to the liquid surface. Through stirring, sludge deposition is prevented, increasing the contact frequency and collision probability, thus improving the probability of oil droplets and suspended solids being captured by the microbubbles. This further maintains sufficient contact between oil droplets and microbubbles, improving the oil-water separation effect. Subsequently, the water inlet channel is raised and lowered, the slide slides along the linear guide rail, and the contact components are guided along the transition ramp. At this point... The spring changes from its initial compressed state to its elastic recovery state; at this time, the pusher plate enters the edge of the opening on the top surface of the treatment box, the pusher plate extends into the bottom of the scum layer, and is pushed towards the oil outlet as the slide block slides, pushing the floating oil and some scum as a whole until it reaches the position of the pusher part. The inclined surface on one side of the pusher plate abuts against the pusher part, and the pusher plate pushes the connecting plate upward. At this time, the sewage carried in the scum layer flows back into the treatment chamber along the narrow channel to prevent water from being carried out of the system. The scum is then transported to the position of the oil outlet and sent to the oil collection tank to ensure that the scum is accurately and stably pushed to the oil outlet, avoiding incomplete separation of the scum layer or water in the oil layer. 2. By setting up independently rotating grid one, grid two and sealing unit, when one side of the area is blocked, the other side can still intercept normally, thus working effectively and preventing the entire filtration system from failing due to blockage on one side. In addition, the waste box intercepts the sludge flow secondary. When using the waste box, the sealing unit fits tightly to the waste box to ensure the airtightness of the entire device and prevent the leakage of impurities. 3. By transferring the sludge from one processing chamber to another, the sludge passes through the screens on both sides in sequence as the screen plate rotates. After passing through the screens, sludge particles of different sizes are separated and enter different flow paths. The horizontal cylinder pushes the cleaning orifice plate to slide to the position of the screen. High-pressure airflow is sprayed onto the screen through the holes of the cleaning orifice plate to remove the suspended solids, oil droplets or other impurities accumulated in the screen and restore the filtration capacity of the screen.

Detailed Implementation

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0021] Please see Figures 1-9 As shown, the present invention provides a sludge oil-water high-efficiency separation and treatment device, including a treatment box 1, a liftable water inlet channel 2 connected to the opening on the top surface of the treatment box 1, and two treatment chambers inside the treatment box 1, one of which is connected to the opening on the top surface of the treatment box 1. A blocking plate 32 for sealing is provided at the connection between the two processing chambers; A stirring rod 20 for stirring sludge is installed at intervals on the main shaft inside a processing chamber, and a porous nozzle 21 for introducing dissolved air into the sludge and releasing microbubbles is installed on one side of the upper part of a processing chamber. Oil droplets and suspended particles are adsorbed by microbubbles, forming gas-solid aggregates that float to the water surface; The outer side of the opening on the top surface of the processing box 1 is provided with a downwardly recessed strip groove 33, and a linear guide rail 34 is installed inside the strip groove 33. A transition ramp 36 is provided on one side of the linear guide rail 34. The linear guide rail 34 is slidably provided with a slide block 18, and the inner cavity of the slide block 18 is provided with a spring 37. One end of the spring 37 is fixed with a connecting plate 35, and the bottom edge of the connecting plate 35 is provided with a contact member 38 that abuts and cooperates with the transition inclined platform 36. The bottom center of the connecting plate 35 is provided with an oil-scraping plate 19 for horizontally scraping the floating oil stains. The bottom side of the oil-scraping plate 19 is inclined, and the inner surface of the oil-scraping plate 19 is provided with a slope that is narrow at the top and wide at the bottom. The interior of the processing box 1 is provided with an oil collection tank 24 that communicates with a processing chamber. An oil outlet is provided at the connection between the processing chamber and the oil collection tank 24. A docking plate 22 is rotatably installed inside the oil outlet. The interior of a processing chamber is provided with a pusher 23, which is used in conjunction with the inclined surface at the bottom of the oil-pushing plate 19. The surface of the pusher 23 is provided with fine grooves.

[0022] When using, such as Figure 1 As shown, at this time, the water inlet channel 2 is accurately connected to the opening on the top surface of the treatment tank 1, which facilitates the passage of sludge fluid and allows the sludge fluid to smoothly enter one of the treatment chambers. The connection between the two processing chambers is sealed by the blocking plate 32 to prevent sludge from flowing into the other processing chamber and causing disturbance; Then, the rotating main shaft drives the staggered stirring rods 20 to stir the sludge fluid at a uniform speed, so that the sludge is suspended evenly. Then, dissolved air reflux water is introduced into the treatment chamber through the porous nozzle 21. When the reflux water enters under reduced pressure, it releases micro (small) bubbles, providing a bubble medium. The micro bubbles attach to the surface of oil droplets and suspended particles, reducing their density and causing them to form gas-solid aggregates that quickly float to the liquid surface. After settling, a scum (oil) layer is enriched in the upper layer of the treatment chamber, water is in the middle layer, and sediment is in the lower layer, thus achieving oil-water stratification. The stirring action prevents sludge deposition, increases the contact frequency and collision probability, and improves the probability of oil droplets and suspended solids being captured by microbubbles, further maintaining full contact between oil droplets and microbubbles and improving the oil-water separation effect. Immediately afterwards, such as Figure 5 As shown, the shaded area represents the height of the scum (oil) layer. The water inlet channel 2 is lifted and opened. At this time, the slide 18 slides along the linear guide rail 34. When it reaches the opening on the top surface of the treatment box 1, the contact piece 38 is guided by the transition ramp 36, that is, it moves from the upper platform to the lower platform. At this time, the spring 37 changes from the initial compressed state to the elastic recovery state. like Figure 7As shown, the contact member 38 is subjected to the downward elastic thrust of the connecting plate 35. At this time, the oil pusher 19 enters the edge of the opening on the top surface of the treatment box 1. The oil pusher 19 extends into the bottom of the scum (oil) layer and is pushed towards the oil outlet as the slide seat 18 slides. The oil pusher 19 is close to the bottom of the oil layer and pushes the oil and part of the scum as a whole until it reaches the position of the pusher 23. The inclined surface on one side of the oil pusher 19 abuts against the pusher 23. The oil pusher 19 pushes the connecting plate 35 upward. At this time, the sewage carried in the scum (oil) layer flows back into the treatment chamber along the narrow channel to prevent water from being carried out of the system. The scum (oil) is then transported to the position of the oil outlet. At this time, the docking plate 22 automatically opens, and the scum (oil) enters the oil collection tank 24 to ensure that the scum (oil) layer is accurately and stably pushed to the oil outlet, avoiding incomplete separation of the scum (oil) layer or water in the oil layer.

[0023] See Figure 1 and Figure 5 As shown, the front surface of the processing box 1 is provided with an oil drain port 5 that communicates with the oil collection tank 24; An electric push rod is hinged to the top of the inner cavity of the oil collection tank 24, and the pushing end of the electric push rod is hinged to the docking plate 22. A drain outlet with a valve is provided in the middle of a processing chamber. When the valve is opened, the sewage in the middle is discharged through the drain outlet. The docking plate 22 is rotated and opened by an electric push rod, so that the scum layer can enter the oil collection tank 24. The opening and closing state of the oil collection tank 24 is controlled to ensure that the oil scum can enter the oil collection tank 24 smoothly. After closing, the oil scum is prevented from flowing back. The scum layer in the oil collection tank 24 is discharged from the oil outlet 5.

[0024] See Figure 2 As shown, a partition 6 is fixedly provided in the middle of the inner cavity of the water inlet channel 2. Two limiting grooves 8 are provided on the arc surface at the bottom of the partition 6, and two fitting circular plates 9 are rotatably provided at the two edges inside the arc surface of the partition 6. The two fitting circular plates 9 are rotatably set by bearings. The outer surface of the fitting circular plate 9 is slidably set with the corresponding limiting groove 8; A grid 10 is fixedly connected to one side surface of a fitted circular plate 9; Another mesh 11 is fixedly connected to one side surface of the fitting circular plate 9.

[0025] In this state, the sludge flow enters the two sides of the baffle 6 through the inlet channel 2, that is, it is evenly distributed to both sides. The bar screen 10 and bar screen 21 intercept the branches or plastic impurities in the sludge flow. Both bar screen 10 and bar screen 211 can rotate independently. When rotating, the fitting circular plate 9 always rotates within the limiting groove 8. With two independently rotating grilles 10 and 11, if one side of the filter becomes clogged, the other side will still block the blockage, thus preventing the entire filter system from failing due to unilateral blockage.

[0026] See Figure 3 As shown, the inner cavity of the water inlet channel 2 is provided with a limiting groove 13 located below the first grid 10 and the second grid 11. The waste box 12 is slidably provided inside the limiting groove 13 along the track direction. The bottom surface of the inner cavity of the waste box 12 is provided with a grid plate. An actuator cylinder is installed on the processing box 1 to move the waste box 12; The interior of the limiting groove 13 is equipped with a sealing unit that limits the movement of the waste container 12; After passing through the first grid 10 and the second grid 11, the sludge flows into the waste bin 12. The waste bin 12 performs secondary interception of the sludge flows to prevent impurities such as branches from entering the treatment box 1. During the secondary interception, the waste bin 12 slides into the limiting groove 13, and the sealing unit fits tightly against the waste bin 12 at this time to ensure the airtightness of the entire device and prevent the leakage of impurities. After the first grid 10 and the second grid 11 rotate 180 degrees, the intercepted branches or plastic impurities are dumped into the waste bin 12 below. Then the sealing unit releases the pressing action, and the waste bin 12 is instructed by the execution cylinder to slide along the track direction of the limit groove 13, and the impurities in the waste bin 12 are cleaned by machine or manually.

[0027] See Figure 4 As shown, the sealing unit includes a side plate, and a reference plate 14 is fixed on each of the four edge surfaces of the side plate. An expansion member 15 is connected to the surface of each reference plate 14, and a push member 16 that slides along the side plate is connected to the expansion end of each expansion member 15. The expansion member 15 is an airbag. The distance between two adjacent reference plates 14 at the same height matches the length of the waste bin 12; When the waste bin 12 enters the limiting groove 13 and starts working, the expansion of the air bladder causes the pushing part 16 to seal and fit tightly with the waste bin 12, preventing sludge fluid and impurities from leaking out of the gaps and ensuring that the sludge fluid treatment process is not disturbed.

[0028] See Figure 1 and Figure 8 As shown, the upper surface of the processing box 1 is provided with a sludge scraping chamber 3 for scraping off the sludge on both sides of the blockage plate 32. A fixing post 30 is fixedly provided on the bottom surface of the inner cavity at the connection between the two processing cavities, and a slot 31 is provided in the middle of the bottom surface of the blocking plate 32; The card slot 31 fits against the surface of the fixed post 30, and the blocking plate 32 contacts the inner wall of the connection between the two processing cavities through a sealing gasket. When the sludge fluid enters the processing chamber where the stirring rod 20 is located, the blocking plate 32 is given a downward command by the lifting cylinder. When the blocking plate 32 moves downward, it slides and fits against the outer wall of the fixed column 30 until the end of the slot 31 fits tightly against the main shaft. At this time, the blocking plate 32 contacts the inner wall of the connection between the two processing chambers through the sealing gasket to prevent the sludge fluid from leaking and improve the sealing of the entire processing process. When the blockage plate 32 rises, the sludge on both sides of the blockage plate 32 is scraped and disposed of in a timely manner by the sludge scraping chamber 3, thus avoiding sludge accumulation and blockage.

[0029] See Figure 9 As shown, the end of the main shaft extends into another processing chamber, and a sieve plate 28 is installed on the outer surface of the main shaft. The inner sides of the other processing chamber are respectively provided with sieves 26 of different apertures. An electric pump is installed inside the processing chamber 1 to transfer sludge from one processing chamber to another. During the transfer, the blocking plate 32 is in normal sealing operation. After the sludge is completely transferred to another processing chamber, the main shaft continues to drive the screen plate 28 to rotate, which accelerates the screening of sludge impurities. During screening, the mud particles pass through the screens 26 on both sides in sequence as the screen plate 28 rotates. After passing through the screens 26, mud particles of different sizes are separated and enter different flow paths.

[0030] See Figure 5 and Figure 9 As shown, the outer surface of one processing chamber is provided with a cleaning orifice plate 25 that is pushed by a transverse cylinder and slidably limited to another processing chamber. There are two cleaning orifice plates 25. The airflow ejected from the cleaning perforated plate 25 acts on the clogged sieve holes of the screen 26; The cleaning perforated plate 25 is pushed by the horizontal cylinder to slide in a limited position and move towards another processing chamber. When it reaches the position of the screen 26, high-pressure airflow is sprayed onto the screen 26 through the holes of the cleaning perforated plate 25 to remove the suspended solids, oil droplets or other impurities accumulated in the screen 26 and restore the filtration capacity of the screen 26.

[0031] See Figure 9 As shown, both sides of the processing box 1 are provided with discharge channels, and each discharge channel is slidably installed with a mud collection box 7 for collecting mud of the corresponding aperture. The two mud collection boxes 7 are brought closer or further apart by a two-way screw and a guide rail on the discharge channel; When the sludge flows through the treatment device, the sludge particles are separated by the screen 26 and enter the corresponding sludge collection box 7. The sludge collection box 7 accumulates the particles and prepares them for subsequent processing. The two sludge collection boxes 7 are driven by a two-way screw to move away from each other along the guide rail on the discharge channel until they reach the outlet end of the discharge channel, which facilitates the subsequent extrusion and dewatering treatment of the sludge collection box 7.

[0032] In use, this invention, through the setting of the oil-pushing plate 19, contact element 38, and transition ramp 36, initially ensures that the water inlet channel 2 is accurately aligned with the opening on the top surface of the treatment tank 1, facilitating the passage of sludge fluid. Dissolved air in the return water, introduced through the porous nozzle 21, releases microbubbles. These microbubbles adhere to the surface of oil droplets and suspended particles, forming gas-solid aggregates that quickly float to the liquid surface. The stirring action prevents sludge deposition, increases the contact frequency and collision probability, and enhances the probability of oil droplets and suspended matter being captured by the microbubbles, further maintaining sufficient contact between oil droplets and microbubbles and improving the oil-water separation effect. Subsequently, the water inlet channel 2 is raised and lowered to open, the slide 18 slides along the linear guide rail 34, and the contact element 38 is guided by the transition ramp 36. At this time, the spring 37 changes from the initial compressed state to the elastic recovery state; at this time, the oil pusher 19 enters the edge of the opening on the top surface of the processing box 1, the oil pusher 19 extends into the bottom of the scum layer, and is pushed towards the oil outlet as the slide seat 18 slides, pushing the floating oil and part of the scum as a whole until it reaches the position of the push part 23. The inclined surface on one side of the oil pusher 19 abuts against the push part 23, and the oil pusher 19 pushes the connecting plate 35 upward. At this time, the sewage carried in the scum layer flows back into the processing chamber along the trough to prevent water from being carried out of the system. The scum is transported to the position of the oil outlet and sent to the oil collection tank 24 to ensure that the scum is accurately and stably pushed to the oil outlet, avoiding incomplete separation of the scum layer or water in the oil layer. By setting up independently rotating grid 10, grid 2 11 and sealing unit, when one side of the area is blocked, the other side can still intercept normally and work effectively, thus preventing the entire filtration system from failing due to blockage on one side. In addition, the waste box 12 intercepts the sludge flow secondary. When using the waste box 12, the sealing unit fits tightly against the waste box 12 to ensure the airtightness of the entire device and prevent the leakage of impurities. By transferring the sludge from one processing chamber to another, the sludge passes sequentially through the screens 26 on both sides as the screen plate 28 rotates. After passing through the screens 26, sludge particles of different sizes are separated and enter different flow paths. Driven by the transverse cylinder, the cleaning perforated plate 25 is limited to slide to the position of the screen 26. High-pressure airflow is sprayed onto the screen 26 through the holes of the cleaning perforated plate 25 to remove suspended solids, oil droplets or other impurities accumulated in the screen 26 and restore the filtration capacity of the screen 26.
