Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a detachable wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. People often dump household garbage into rivers or ditches, which adds trouble to wastewater treatment. In wastewater treatment, additives such as activated carbon are usually used to treat wastewater. At present, most of them use a single rotating agitator shaft to mix wastewater and additives, and the mixing efficiency is difficult to improve in one step.

[0003] Chinese Patent CN114560539B, published on January 12, 2024, discloses a high-efficiency wastewater treatment device, including a baffle, a mounting ring, fixing plates, an electromagnet, a rotating frame, and stirring rods. The mounting ring can move up and down inside the baffle. Multiple fixing plates are detachably connected to the mounting ring by bolts. Each fixing plate is equipped with an electromagnet. The rotating frame can rotate around its own axis directly below the baffle. Multiple stirring rods are installed on the rotating frame. The device also includes a rotating shaft, grooved rods, and telescopic nets. The rotating shaft is rotatably connected to the baffle. Two grooved rods are installed on the rotating shaft. Two telescopic nets are provided on the rotating shaft. One end of each telescopic net is fixed to the rotating shaft, and the other end of each telescopic net can be unfolded along the two grooved rods. This device facilitates the collection of metals from wastewater. However, the device is prone to causing localized high-concentration suspensions of deposited sludge during agitation, which may increase the load on subsequent filtration. The drive motor, cylinders and other electrical control components are exposed to a high-humidity and corrosive wastewater environment for a long time, requiring high protection levels and sealing. The external lifting device is prone to vibration and fatigue cracks under the reaction force of agitation.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example 1 Please see Figures 1-13 The present invention provides a technical solution: a detachable sewage treatment device, including a treatment tank 1 and a clean water inlet 2 installed on the outer wall of the treatment tank 1. A door 3 is slidably connected to the outer wall of the treatment tank 1. Observation windows 4 are provided on the outer walls on both sides of the treatment tank 1. A sludge tank 5 is provided inside the treatment tank 1. A sewage inlet 6 is fixedly connected to the outer wall of the treatment tank 1. A clean water tank 7 is fixedly connected inside the treatment tank 1, and a clean water inlet 2 is fixedly connected inside the clean water tank 7. A lifting mechanism is provided inside the treatment tank 1. A filtration mechanism is provided on the outer wall of the bottom end of the lifting mechanism. A rotating component 19 is provided on the inner wall of the filtration mechanism. A quick-release mechanism 26 is provided on the outer wall of the filtration mechanism. The filtration mechanism includes a pressure-boosting filtration device for increasing the pressure above the sewage and filtering it, and a sewage discharge device for discharging the sludge generated after the sewage is filtered.

[0022] In use, the treatment tank 1 serves as the overall frame, with a clean water outlet 2 on the outer wall for discharging purified water. The hatch 3 moves up and down along the slide rail for sealing and maintenance. The observation window 4 allows for real-time observation of the internal operation. The sludge tank 5 is located at the bottom to collect sludge after filter pressing. The wastewater outlet 6 directs raw water into the retention tank 10. The clean water pool 7 is connected to the clean water outlet 2 to complete secondary water purification and storage. The lifting mechanism consists of a lifting box 8, a reduction motor 12, pulleys 13, and steel cables 14. The reduction motor 12 drives the pulleys 13 to raise and lower the steel cables 14 to lift the sliding frame 11, achieving overall lifting. The sliding frame 11 is supported by columns 9. Connected to the retention tank 10, the filtration mechanism is installed at the bottom of the sliding frame 11, including a booster roller 21 and a filter roller 24. The liquid-blocking fan blades 22 on the outer wall of the booster roller 21 rotate to draw in the liquid, the filtrate holes 23 perform preliminary filtration, and the conveying blades 28 inside the threaded booster pipe 27 rotate in the opposite direction to push the sludge to the connecting pipe 29 and discharge it into the sludge tank 5 through the anti-clogging drain pipe 18. The rotating component 19 realizes the differential rotation of the booster roller 21 and the filter roller 24 to enhance centrifugal filtration. The quick-release mechanism 26 can separate the rollers for easy cleaning. The whole system completes booster filtration and continuous sewage discharge under mechanical linkage and sealing structure.

[0023] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The pressurized filtration device includes a pressurized drum 21, with liquid intercepting fan blades 22 on the outer wall of the pressurized drum 21 and filtrate holes 23 adapted to the liquid intercepting fan blades 22 on the outer wall of the pressurized drum 21. A filter drum 24 is connected to the bottom end of the pressurized drum 21, and a quick-release mechanism 26 adapted to the filter drum 24 is provided on the outer wall of the bottom end of the pressurized drum 21. A filter element plate 25 is slidably connected in the inner wall interlayer of the filter drum 24. The filter element plate 25 is shaped as a corrugated ring and is made of polyester fiber.

[0024] In use, the booster drum 21 is driven to rotate by the rotating component 19. The liquid intercepting fan blades 22 on the outer wall agitate the liquid to form a low-pressure zone, which draws the sewage in the retention tank 10 radially. The liquid first completes the initial filtration through the filter holes 23 on the inner side of the liquid intercepting fan blades 22, and then enters the filter drum 24 downward. The inner wall of the filter drum 24 is interlayered with corrugated annular polyester fiber filter element plates 25. The corrugated structure increases the effective filtration area. Under the action of centrifugal force and pressure difference, the polyester fiber layer intercepts sludge, allowing water to pass through the filter element plates 25 and be discharged outward. The bottom end of the filter drum 24 is connected to the flange of the booster drum 21 through the quick-release mechanism 26. The sliding of the pin 2603 and the reset seat 2605 realizes tool-free disassembly and assembly. The filter element plates 25 can be slid out and replaced along the interlayer. The entire device achieves continuous high-pressure filtration and convenient maintenance through the synergy of rotational pressurization and quick disassembly.

[0025] Please see Figure 6 , Figure 7 and Figure 9 The sewage discharge device includes a booster roller 21, with a threaded booster pipe 27 rotatably connected inside the booster roller 21. One end of the threaded booster pipe 27 is connected to the rotating assembly 19. A conveying blade 28 is provided inside the threaded booster pipe 27, and the bottom end of the conveying blade 28 is rotatably connected to the center of the inner wall of the filter roller 24. A spiral blade is fixedly connected to the threaded booster pipe 27, and a connecting pipe 29 is rotatably connected to the top end of the threaded booster pipe 27. A sealing ring adapted to the threaded booster pipe 27 is provided inside the connecting pipe 29. One end of the connecting pipe 29 is connected to the inside of the anti-clogging sewage pipe 18, and one end of the anti-clogging sewage pipe 18 is connected to the inside of the sludge tank 5.

[0026] In use, the rotating component 19 drives the threaded pressure boosting pipe 27 to rotate inside the pressure boosting drum 21. The spiral blades on the outer wall of the threaded pressure boosting pipe 27 push the filtrate downward to form high pressure. The conveying blades 28 in the inner cavity rotate in the opposite direction to convey the sludge accumulated at the bottom of the filter drum 24 upward along the inner cavity of the threaded pressure boosting pipe 27. The sludge enters the anti-clogging drain pipe 18 through the connecting pipe 29. The anti-clogging drain pipe 18 is connected to the sludge tank 5 to achieve continuous discharge. The sealing ring in the connecting pipe 29 prevents high-pressure oil and water backflow. The whole system completes high-pressure filtration and non-clogging discharge under mechanical linkage. The corrugated ring polyester fiber filter plate 25 provides a large surface area for efficient interception, reduces the frequency of downtime cleaning, and improves system stability and processing efficiency.

[0027] Please see Figure 6 , Figure 9 and Figure 10The lifting mechanism includes a lifting box 8, a column 9 fixedly connected to the bottom of the lifting box 8, a holding box 10 fixedly connected to the bottom of the column 9, a sliding frame 11 slidably connected in a groove on the inner wall of the column 9, a reduction motor 12 fixedly connected inside the lifting box 8, a pulley 13 fixedly connected inside the lifting box 8, a steel cable 14 slidably connected inside the pulley 13, a housing cover 15 fixedly connected to the outer wall of the sliding frame 11, a telescopic column 16 fixedly connected to the inner wall of the housing cover 15, and the bottom end of the telescopic column 16 fixedly connected to the holding box 10, a motor box 17 fixedly connected to the bottom of the housing cover 15, an anti-clogging drain pipe 18 fixedly connected inside the motor box 17, a rotating component 19 fixedly connected to the inner wall at the bottom of the motor box 17, a gearbox 20 connected to the bottom of the rotating component 19, and a quick-release mechanism 26 provided on the outer wall of the gearbox 20.

[0028] In use, the output shaft of the geared motor 12 is fitted with a take-up reel to actively wind the steel cable 14. The outer wall of the movable end of the steel cable 14 is connected to the sliding frame 11, and the fixed end of the steel cable 14 is connected to the take-up reel. After the steel cable 14 is led out from the take-up reel, it first passes upward through the pulley 13 fixed to the top of the lifting car 8 to form tension guidance, and then connects downward to the sliding frame 11. The sliding frame 11 rises and falls along the inner slot of the column 9. The telescopic column 16 extends and extends between the car cover 15 and the holding box 10 to guide and absorb vibration. The car cover 15 and the motor car 17 rise and fall as a whole with the sliding frame 11. The rotating component 19 inside the motor car 17 is output through the gearbox 20. The quick-release mechanism 26 on the outer wall of the gearbox 20 realizes quick disassembly and assembly when the pin 2603 and the reset seat 2605 are pulled by external force. The holding box 10 provides rigid support for the column 9 and the lifting system. The lifting mechanism completes the lifting positioning and maintenance operations through the cooperation of the take-up reel and the pulley 13.

[0029] Please see Figure 12 and Figure 13 The rotating assembly 19 includes a power gear 1901. A fixed frame 1902 is rotatably connected to the outer wall of one end of the power gear 1901, and the fixed frame 1902 is fixed inside the motor housing 17. An auxiliary gear 1904 is rotatably connected to the shaft at each end of the fixed frame 1902. A rotating gear 1903 meshes with the outer wall of the auxiliary gear 1904, and a gear ring 1905 meshes with the outer wall of the auxiliary gear 1904.

[0030] In use, the torque of the servo motor 32 is input to the power gear 1901 via the transmission belt 50, which directly drives the threaded pressure tube 27 to rotate. The rotating gear 1903 on the same axis rotates synchronously with the threaded pressure tube 27 and drives the auxiliary gear 1904 to rotate on the fixed frame 1902. The auxiliary gear 1904 then drives the gear ring 1905 to rotate in the opposite direction around the threaded pressure tube 27. The gear ring 1905 is connected to the rotating disk 37 by the bolt 36, which in turn drives the gear box 20 and the pressure drum 21 to rotate in the opposite direction at a low speed, forming an inner and outer coaxial differential rotation system. This generates additional shearing force inside the filter drum 24 to prevent sludge from solidifying and clumping. The fixed frame 1902 remains stationary to provide rigid support for the auxiliary gear 1904 to avoid shaking. The overall structure is compact and the torque transmission is stable. The differential motion improves the filtration and sludge discharge efficiency. During disassembly and assembly, only the retaining ring needs to be removed to remove the rotating assembly 19 as a whole, making maintenance quick.

[0031] Please see Figure 12 and Figure 13 The quick-release mechanism 26 includes a first mounting base 2601 disposed at the bottom of the gearbox 20 and the booster roller 21, and a second mounting base 2607 disposed on the outer wall of the top of the booster roller 21 and the filter roller 24. The first mounting base 2601 has a first sliding groove 2602 inside. The second mounting base 2607 has a reset seat 2605 slidably connected inside. The bottom end of the reset seat 2605 is fixedly connected to a pull ring 2606. The top end of the first mounting base 2601 is fixedly connected to a magnet 2608. The first mounting base 2601 has a pin 2603 that matches the first sliding groove 2602 inside, and the pin 2603 is slidably connected to the first sliding groove 2602.

[0032] In use, the reset seat 2605 is first placed inside the second mounting seat 2607. Pushing the reset seat 2605 causes the magnet 2608 to attract the reset seat 2605 and keep it locked. The pin 2603 is then slid into the first groove 2602 of the first mounting seat 2601, with its front end extending into the reset seat 2605 to form an axial position. To disassemble, the pin 2603 is pulled out along the first groove 2602 to release the connection between the first mounting seat 2601 and the second mounting seat 2607. Pulling the pull ring 2606 causes the reset seat 2605 to slide along the second mounting seat 2607 and disengage from the magnetic field of the magnet 2608, achieving tool-free quick disassembly between the gearbox 20, the booster roller 21, and the filter roller 24. The magnet 2608 provides continuous magnetic force to achieve quick installation and disassembly and prevent vibration from causing loosening. The reset seat 2605 and the pin 2603 form a secondary lock to improve connection reliability. The overall structure shortens on-site maintenance time and reduces labor intensity.

[0033] Please see Figure 6 , Figure 8 , Figure 9 and Figure 10The quick-release mechanism 26 also includes a reset seat 2605 disposed inside the second mounting base 2607. The reset seat 2605 is provided with a second sliding groove 2604 adapted to the pin 2603. The second mounting base 2607 is provided with a limiting groove 2609 adapted to the second sliding groove 2604. The first mounting base 2601 is provided with a limiting groove 2609 adapted to the second sliding groove 2604, and the limiting groove 2609 is slidably connected to the second sliding groove 2604. The outer wall of the reset seat 2605 is provided with a slider 2610 adapted to the limiting groove 2609, and the slider 2610 is slidably connected to the limiting groove 2609.

[0034] In use, the reset seat 2605 and the pin 2603 are axially clamped together by the second slide groove 2604. The limiting groove 2609 and the slider 2610 provide radial guidance and prevent the reset seat 2605 from rotating or tilting. The first mounting seat 2601 and the second mounting seat 2607 are both provided with symmetrical limiting grooves 2609 to ensure that the pin 2603 always slides in a straight line. During quick release, only the pull ring 2606 needs to be pulled to release all constraints. The slider 2610 and the limiting groove 2609 cooperate to make the movement trajectory of the reset seat 2605 accurate and avoid jamming. The secondary guide structure improves the coaxiality of the pin 2603 and reduces wear. The whole system realizes one-handed operation and tool-free quick release, shortening downtime for maintenance.

[0035] Please see Figure 4 , Figure 5 ,and Figure 8 An electromagnetic coil 30 is fixedly connected inside the motor housing 17. A rotor 31 is rotatably connected inside the electromagnetic coil 30. A servo motor 32 is fixedly connected inside the motor housing 17. A transmission gear 49 is fixedly connected to the output shaft of the servo motor 32. A transmission toothed belt 50 is connected to the outer wall of the transmission gear 49, and the transmission toothed belt 50 meshes with the transmission gear 49. The transmission gear 49 is rotatably connected to the inner wall of the motor housing 17. A fixed disk 38 is fixedly connected inside the motor housing 17. A rotating disk 37 is rotatably connected to the outer side of the fixed disk 38. Bolts 36 are provided on the inner wall of the rotating disk 37. The rotating disk 37 is connected to the gearbox 20 by bolts 36.

[0036] In use, the servo motor 32 drives the transmission gear 49 to rotate. The transmission gear 49 transmits torque to the power gear 1901 through the meshing transmission belt 50. The power gear 1901 drives the threaded pressure tube 27 to rotate. The electromagnetic coil 30 is energized to generate a rotating magnetic field, which causes the rotor 31 to drive the conveying blades 28 to rotate in the opposite direction without contact. The rotor 31 and the threaded pressure tube 27 run at different speeds. The rotating disk 37 is fixed to the gearbox 20 by bolts 36 and cooperates with the bearing of the fixed disk 38, so that the filter roller 24 below rotates synchronously at a slow speed. The whole system forms a differential transmission cooperative system of motor drive, transmission belt and electromagnetic coupling.

[0037] Please see Figure 6 , Figure 7 and Figure 8 The filter basket 39 is slidably connected inside the retention box 10. The filter brick 40 is slidably connected inside the filter basket 39. The outer surface of the filter brick 40 is provided with a slot 33. The outer surface of the filter brick 40 is provided with a plug-in block 34, and the plug-in block 34 is slidably connected to the slot 33. The outer wall of the filter brick 40 is provided with a separation seam 35. The top of the filter basket 39 is fixedly connected with a handle 41. The bottom of the filter basket 39 is provided with a mounting groove 42. The retention box 10 is fixedly connected with a mounting block 43, and the mounting block 43 is slidably connected to the mounting groove 42.

[0038] In use, first gently tap along the separation seam 35 to separate the filter bricks, then slide the plug-in block 34 into the slot 33 to form a filter wall. Assemble multiple filter bricks 40 facing each other, and then push the assembled filter bricks 40 into the filter basket 39 to make them fit tightly. Then, lower the filter basket 39 vertically along the slide rail on the inner wall of the retention box 10 until the bottom end engages with the mounting block 43 for limitation. The plug-in block 34 and the slot 33 are tenon-and-mortise engaged to achieve quick positioning and expandable assembly of the filter bricks 40. The separation seam 35 undergoes slight deformation when compressed to improve sealing and prevent the bricks from cracking. The openings on the side wall of the filter basket 39 and the pores of the filter bricks 40 form multi-stage interception. The whole unit constitutes a pull-out modular primary filter unit. Tool-free assembly shortens replacement time. The separation seam 35 allows workers to quickly disassemble and install the bricks and release thermal expansion and contraction stress to extend the life of the filter bricks 40. The filter basket 39 can be pulled out as a whole for offline cleaning, reducing workers' contact with sewage. The plug-in structure allows for mass production of filter bricks 40.

[0039] Please see Figure 6 , Figure 7 and Figure 9 The inside of the retention box 10 is fixedly connected to a limiting rotating seat 44. A limiting rack 45 is provided on the inner wall of the retention box 10. A lifting gear 46 is meshed on the limiting rack 45. A sliding head 47 is fixedly connected to one side of the lifting gear 46, and the sliding head 47 is slidably connected to the inside of the limiting rack 45. A cleaning brush 48 is fixedly connected between the two sets of lifting gears 46.

[0040] In use, the filter basket 39 is vertically placed into the retention box 10 by pulling the handle 41, aligning the mounting groove 42 with the mounting block 43 and sliding it in to complete the limiting position. The bottom end of the filter roller 24 is inserted into the limiting rotating seat 44 to form a rotation fulcrum. When cleaning is required, the lower end of the steel cable 14 is fixed to the inner shaft between the two sets of sliding heads 47. The outer wall of the inner shaft rotates with a cleaning brush 48, and the lifting gears 46 mesh and roll synchronously. The cleaning brush 48 between the two sets of lifting gears 46 rotates against the wall to scrape off the sludge. When it descends to its original position, the mounting groove 42 engages with the mounting block 43 again to ensure the filter basket 39 is positioned. The cooperation between the mounting groove 42 and the mounting block 43 limits the radial displacement of the filter basket 39. The filter roller 24 is kept coaxial with the retention box 10 during rotation and bears the axial load. The limiting rack 45 provides guidance for the sliding head 47. The lifting gear 46 meshes with the involute of the limiting rack 45 to ensure smooth lifting. The silicone spiral blade of the cleaning brush 48 scrapes the inner wall of the retention box 10 evenly during rotation and lifting and removes the attached substances. The handle 41 enables quick loading and unloading by a single person to reduce downtime. The plug-in structure of the mounting slot 42 and the mounting block 43 avoids tool maintenance. The limiting rotating seat 44 reduces roller vibration and wear. The synchronous lifting and lowering of the cleaning brush 48 realizes automatic cleaning and reduces the risk of manual exposure. The whole keeps the filter channel unobstructed and extends the continuous operation cycle.
