Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, and in particular to a multi-stage integrated filtration wastewater treatment device. Background Technology
[0002] With the acceleration of urbanization and rapid industrial development, the volume of sewage discharge is increasing daily, and the composition of sewage is becoming increasingly complex, including large amounts of solid waste, silt, and inorganic substances such as nitrogen and phosphorus. If this sewage is discharged directly without effective treatment, it will cause serious pollution to water bodies, soil, and other ecological environments, affecting ecological balance and human health.
[0003] Traditional wastewater treatment methods primarily rely on processes such as sedimentation, filtration, and biological treatment. However, in the initial stages of wastewater treatment, the handling of larger solid waste items, such as plastic bags and tree branches, is often inefficient. Most existing filtration devices use fixed filter screens, which are easily clogged by larger debris, leading to decreased filtration efficiency, frequent cleaning, increased maintenance costs, and increased labor intensity. Furthermore, cleaning debris attached to the filter screen is difficult and incomplete, negatively impacting subsequent wastewater treatment outcomes.
[0004] Furthermore, the collection and transportation of waste during wastewater treatment lacks effective automation, typically requiring manual cleaning and handling, which is not only inefficient but also poses certain safety hazards. At the same time, traditional wastewater treatment processes have limited effectiveness in removing inorganic substances such as nitrogen and phosphorus, making it difficult to meet increasingly stringent wastewater discharge standards.
[0005] Therefore, a multi-stage integrated filtration wastewater treatment device is proposed to solve the problem of large debris clogging the initial stage of traditional wastewater treatment. Summary of the Invention
[0006] The purpose of this invention is to provide a multi-stage integrated filtration wastewater treatment device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: A multi-stage integrated filtration wastewater treatment device includes a filtration assembly. The filtration assembly is provided with two symmetrically arranged mounting plates. Both mounting plates are provided with annular channels. A plurality of support shaft groups are slidably arranged between the two annular channels. Each support shaft group includes two support shafts. In the same support shaft group, both ends of the two support shafts are rotatably connected to a connector 1. In two adjacent support shaft groups, the two adjacent support shafts are rotatably connected to a connector 2. The connector 1 and connector 2 are arranged sequentially on the outside of the mounting plate. Between the two mounting plates and between two adjacent support shafts, there are several connecting parts three rotatably connected, and the connecting parts three between two adjacent support shafts in the longitudinal direction are staggered. A connecting plate is fixedly connected between two adjacent connecting parts three. The connecting plate is fixed with hooks, and several sets of independent double hook channels are formed along the length of the support shaft. Each set of double hook channels contains two independent hook channels. The filter assembly is divided into a lifting zone, a tilting zone, a primary cleaning zone, and a secondary cleaning zone along the sliding trajectory of the support axis. The four zones are connected in sequence and arranged in a closed loop. Each zone covers the entire length of the filter assembly and is matched with several sets of double hook channels.
[0008] Preferably, the lifting area is inclined upwards, so that the hook can hook up garbage in the sewage. The dumping area has a 90° bent structure. When the hook slides into the dumping area with the support shaft, it will gradually become horizontal. Then, after bending and turning, it will become inverted, so that the garbage hooked on the hook can be dumped smoothly. The primary cleaning zone is horizontally aligned with the horizontal section of the dumping zone. The primary cleaning zone includes a primary cleaning roller, which is positioned below the movement path of the hook to perform preliminary cleaning of the garbage remaining on the hook after dumping. The secondary cleaning zone is arranged in parallel with the lifting zone and is connected to the primary cleaning zone and the lifting zone through a corner to form a closed loop. The secondary cleaning zone includes a secondary cleaning roller, which is installed at the connection between the primary cleaning zone and the secondary cleaning zone.
[0009] Preferably, a transmission assembly is also installed on the two mounting plates. The transmission assembly includes a main drive shaft located at the junction of the primary cleaning zone and the secondary cleaning zone. The main drive shaft passes through the two mounting plates and is rotatably connected to them. Both ends of the main drive shaft are fixed with active gear discs, and the teeth of the active gear discs mesh with the transmission chain formed by the first connector and the second connector. The transmission assembly also includes several secondary transmission shafts and driven gear discs. Each driven gear disc is rotatably connected to a secondary transmission shaft. Each secondary transmission shaft is fixed on the opposite sides of the two mounting plates and is located at the intersection between the lifting area, the tilting area, the primary cleaning area, and the secondary cleaning area and the lifting area. Each driven gear disc meshes with the transmission chain and forms a chain drive with the driving gear disc, making the transmission trajectory of the transmission chain the same as the channel trajectory of the annular channel.
[0010] Preferably, a support base is fixed between the two mounting plates, the support base being located below the annular channel and extending to the ground to contact the ground; Two mounting plates are fixed with sealing plates along their length on their sidewalls. A water storage tank is fixed to the other end of each sealing plate. The water storage tank has an inlet on the side near the sealing plate. The sealing plate, the support base, the mounting plate, and the water storage tank together form a closed water flow channel. The water storage tank is connected to the water flow channel through the inlet. Sewage enters the water flow channel from the inlet of the water storage tank.
[0011] Preferably, a support base is fixed between the two mounting plates, the support base being located below the annular channel and extending to the ground to contact the ground; Two mounting plates are fixed with sealing plates along their length on their sidewalls. A water storage tank is fixed to the other end of each sealing plate. The water storage tank has an inlet on the side near the sealing plate. The sealing plate, the support base, the mounting plate, and the water storage tank together form a closed water flow channel. The water storage tank is connected to the water flow channel through the inlet. Sewage enters the water flow channel from the inlet of the water storage tank.
[0012] Preferably, a guide plate is fixed between the two sealing plates. The bottom of the guide plate is in contact with the ground. Several sets of baffles are fixed on the top of the guide plate. The several sets of baffles are evenly arranged along the length direction of the first-stage cleaning roller. Each set of baffles includes two baffles. The positions of the baffles correspond one-to-one with the positions of the annular grooves and extend into their interiors. The top of the baffles does not contact the bottom of the annular grooves to form a mud-pressing channel.
[0013] Preferably, the secondary cleaning roller is fixedly connected to the main drive shaft. The outer wall of the secondary cleaning roller is also provided with several sets of annular grooves along the circumferential direction. The outer wall of the secondary cleaning roller is also provided with several mounting grooves in a circumferential array along the longitudinal direction. A spring is fixed in each mounting groove. A cleaning plate is fixed at the other end of each spring. Several rectangular grooves are provided on the side of the cleaning plate away from the main drive shaft. Each rectangular groove includes two rectangular grooves. Each rectangular groove corresponds one-to-one with an annular groove.
[0014] Preferably, a dust collection device is fixed between the two sealing plates. The dust collection device is located between the water storage tank and the primary cleaning roller and is lower than the rotation axis. It is used to promptly remove the debris and debris cleaned by the primary cleaning roller. The output end of the dust collection device faces the outer wall of the primary cleaning roller and can be accurately aligned with the annular groove area of the cleaning roller to clean the sediment at the bottom of the annular groove. Its input end is fixed with a collection box through a sealed pipeline.
[0015] Preferably, a residue collection box is installed below the secondary cleaning roller, the residue collection box is fixed to the sealing plate, and one end of the residue collection box penetrates the sealing plate to form an opening.
[0016] Preferably, a trash can is fixed to the side walls of the two mounting plates, the trash can is open at both ends, the trash can corresponds to the dumping area, and a conveyor belt is provided at the bottom of the trash can to guide the trash. A partition is fixed to the side of the garbage bin near the primary cleaning roller. The partition is attached to the outer wall of the primary cleaning roller to prevent garbage from falling into the water passage.
[0017] The beneficial effects of the present invention are as follows: By setting up an lifting zone, the present invention uses hooks on the connecting plate to hang up and lift larger garbage such as plastic bags and branches in the sewage during the movement process, thereby achieving preliminary and efficient filtration of sewage, effectively preventing larger garbage from entering the subsequent treatment stage, avoiding blockage and damage to subsequent equipment, and improving the stability and reliability of the entire sewage treatment system. By setting a primary cleaning roller, the hook is embedded in the annular groove as it passes through. The cleaning roller rotates synchronously with the movement of the hook, accurately cleaning the garbage remaining on the hook surface. The cleaning is thorough and leaves no blind spots, effectively removing most of the garbage attached to the hook. By setting up a secondary cleaning roller, the cleaning plate on the secondary roller contacts the surface of the primary cleaning roller under the action of a spring, further cleaning the hook, ensuring the cleanliness of the hook, guaranteeing the subsequent hooking effect, and improving the continuous operation capability of the device.

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] Reference Figures 1-11 A multi-stage integrated filtration wastewater treatment device includes a filter assembly 1. The filter assembly 1 is provided with two parallel and symmetrically arranged mounting plates 101. Both mounting plates 101 are provided with annular channels 102. Several support shaft groups are slidably arranged between the two annular channels 102. Each support shaft group includes two support shafts 103.
[0022] Both ends of the two support shafts 103 in the same support shaft group are rotatably connected to a first connector 104. In two adjacent groups of support shafts 103, two adjacent support shafts 103 are rotatably connected to a second connector 105. The first connector 104 and the second connector 105 are arranged sequentially on the outside of the mounting plate 101.
[0023] By interlacing and sequentially arranging connector 104 and connector 2 105 on the support shaft 103, a transmission chain with a chain-like structure is formed, thereby achieving the effect of synchronously moving each support shaft 103 within the annular channel 102.
[0024] A plurality of connecting parts 106 are rotatably connected between the two mounting plates 101 and between two adjacent support shafts 103, and the connecting parts 106 between two longitudinally adjacent support shafts 103 are staggered, and a connecting plate 107 is fixedly connected between two adjacent connecting parts 106.
[0025] The connecting plate 107 is fixed with hooks 108, and several sets of independent double hook channels are formed along the length direction of the support shaft 103. Each set of double hook channels contains two independent hook channels.
[0026] By driving the transmission chain, the support shaft 103 moves synchronously within the annular channel 102, thereby causing the connecting plate 107 to move between two adjacent support shafts 103 and follow the support shaft 103.
[0027] The filter assembly 1 is divided into a lifting area 2, a tilting area 3, a primary cleaning area 4 and a secondary cleaning area 5 along the sliding trajectory of the support shaft 103. The four areas are connected in sequence and arranged in a closed loop. Each area covers the overall length of the filter assembly 1 and is adapted to several sets of double hook channels.
[0028] In some preferred embodiments, the lifting zone 2 is inclined upwards as a whole, and is used to hook up garbage in sewage through the hook 108.
[0029] The dumping area 3 has a 90° bent structure. When the hook 108 enters the dumping area 3, it will gradually become horizontal and then bend and turn to become inverted, so that the garbage hooked on the hook 108 can be dumped smoothly.
[0030] The primary cleaning zone 4 is horizontally aligned with the horizontal section of the dumping zone 3. The primary cleaning zone 4 includes a primary cleaning roller 401, which is correspondingly positioned below the movement path of the hook 108 and is used to perform preliminary cleaning of the garbage remaining on the hook 108 after dumping.
[0031] The secondary cleaning zone 5 is arranged in parallel with the lifting zone 2, and is connected to the primary cleaning zone 4 and the lifting zone 2 respectively through a corner to form a closed loop. The secondary cleaning zone 5 includes a secondary cleaning roller 501, which is installed at the connection between the primary cleaning zone 4 and the secondary cleaning zone 5. It is used to perform secondary cleaning on the hook 108 after primary cleaning to ensure the cleanliness of the hook 108 and ensure the subsequent hooking effect.
[0032] During the operation of the sewage treatment device, the lifting zone 2 is located in the sewage. As the connecting plate 107 moves with the support shaft 103, the hooks 108 on the connecting plate 107 in the lifting zone 2 hang up and lift up the garbage such as plastic bags and branches in the water. When the garbage on the hooks 108 moves with the connecting plate 107 to the dumping zone 3, the garbage on the hooks 108 flips with the connecting plate 107 and falls off the hooks 108 under the action of gravity. Then, when the connecting plate 107 moves to the primary cleaning zone 4 and the secondary cleaning zone 5, the garbage residue on the hooks 108 will be further cleaned.
[0033] In some preferred embodiments, a transmission assembly 6 is also installed on the two mounting plates 101. The transmission assembly 6 includes a main drive shaft 602, which is located at the junction of the primary cleaning zone 4 and the secondary cleaning zone 5. The main drive shaft 602 passes through the two mounting plates 101 and is rotatably connected to them. The two ends of the main drive shaft 602 are fixed with drive gear discs 601, and the teeth of the drive gear discs 601 mesh with the transmission chain formed by the first connector 104 and the second connector 105.
[0034] The rotation of the main drive shaft 602 drives the drive gear 601 to rotate, thereby driving the movement of the transmission chain.
[0035] The transmission assembly 6 further includes several secondary transmission shafts 603 and driven gear discs 604. Each driven gear disc 604 is rotatably connected to a secondary transmission shaft 603. Each secondary transmission shaft 603 is fixed on the opposite sides of the two mounting plates 101 and is located at the intersection between the lifting zone 2, the tilting zone 3, the primary cleaning zone 4, and the secondary cleaning zone 5 and the lifting zone 2. Each driven gear disc 604 meshes with the transmission chain and forms a chain drive with the driving gear disc 601, making the transmission trajectory of the transmission chain the same as the channel trajectory of the annular channel 102.
[0036] A protective shell 605 is also fixed on the mounting plate 101 to prevent the active gear plate 601 and the driven gear plate 604 from being interfered with by the external environment. A motor 606 is fixed on one side of the protective shell 605. The output end of the motor 606 passes through the protective shell 605 and is fixedly connected to the main drive shaft 602. A sealing cover for preventing water ingress is fixed on the outside of the motor 606.
[0037] When sewage needs to be treated, the motor 606 is started to drive the active gear disk 601 to rotate, and the support shaft 103 is moved through the chain drive formed between the active gear disk 601, the driven gear disk 604 and the transmission chain.
[0038] In some preferred embodiments, a support base 109 is fixed between the two mounting plates 101. The support base 109 is located below the annular channel 102 and extends to the ground to contact the ground, so as to provide stable support for the entire filter assembly 1 and prevent the filter assembly 1 from shaking during operation.
[0039] Sealing plates 110 are fixed to the side walls of the two mounting plates 101 along their length. A water storage tank 111 is fixed to the other end of the sealing plates 110. The water storage tank 111 has an inlet on the side near the sealing plates 110. The sealing plates 110, the support base 109, the mounting plates 101, and the water storage tank 111 together form a closed water flow channel. The water storage tank 111 is connected to the water flow channel through the inlet. Sewage can enter the water flow channel from the inlet of the water storage tank 111, which facilitates the hook 108 to accurately hook and filter the garbage in the sewage. At the same time, the sealing plates 110 can prevent sewage leakage and ensure the cleanliness of sewage treatment operations.
[0040] In some preferred embodiments, the primary cleaning roller 401 includes a rotating shaft 4011, which is located between the two sealing plates 110 and fixedly connected to them. A cleaning roller 4012 is rotatably connected to the outer wall of the rotating shaft 4011. The outer wall of the cleaning roller 4012 is provided with several sets of annular grooves along the circumference. Each set of annular grooves includes two annular grooves 4013. The two annular grooves 4013 correspond one-to-one with the positions and sizes of the two hook channels in each set of double hook channels. When the hook 108 passes through the primary cleaning roller 401, the hook 108 can be embedded in the annular groove 4013. The cleaning roller 4012 rotates synchronously with the movement of the hook 108, thereby accurately cleaning the garbage remaining on the surface of the hook 108, improving the effect of primary cleaning, and ensuring that there are no dead corners in the cleaning.
[0041] Several water passages 4014 for water storage are provided circumferentially between two adjacent annular groove groups.
[0042] In some preferred embodiments, a guide plate 112 is fixed between the two sealing plates 110. The bottom of the guide plate 112 is in contact with the ground, and a number of baffles 113 are fixed on the top of the guide plate 112. The number of baffles 113 are evenly arranged along the length of the primary cleaning roller 401. Each set of baffles 113 includes two baffles 113. The positions of the baffles 113 correspond one-to-one with the positions of the annular groove 4013 and extend into its interior. The top of the baffles 113 does not contact the bottom of the annular groove 4013 to form a mud-pressing channel.
[0043] By rotating the primary cleaning roller 401, the sewage contains easily sedimentable impurities such as mud and sand, which settle at the bottom between the primary cleaning roller 401 and the guide plate 112 and enter the sludge pressing channel. Since the width of the annular groove 4013 is relatively narrow, the sedimentation structure in the sludge pressing channel is relatively stable and moves towards the secondary cleaning zone 5 along with the primary cleaning roller 401.
[0044] In some preferred embodiments, the secondary cleaning roller 501 is fixedly connected to the main drive shaft 602. By starting the motor 606, the main drive shaft 602 and the secondary cleaning roller 501 are driven to rotate, thereby cleaning the hook 108 that has passed through the secondary cleaning roller 501.
[0045] The outer wall of the secondary cleaning roller 501 is also provided with several sets of annular grooves along the circumferential direction. The outer wall of the secondary cleaning roller 501 is also provided with several mounting grooves 502 in a circumferential array along the longitudinal direction. A spring 503 is fixed in each mounting groove 502. A cleaning plate 504 is fixed at the other end of each spring 503. Several rectangular grooves are provided on the side of the cleaning plate 504 away from the main drive shaft 602. Each rectangular groove includes two rectangular grooves 5041. Each rectangular groove 5041 corresponds one-to-one with an annular groove 4013.
[0046] When the hook 108 passes the secondary cleaning roller 501, the hook 108 can be embedded in the annular groove 4013 to clean the hook 108. During the rotation of the secondary cleaning roller 501, the cleaning plate 504 will contact the surface of the primary cleaning roller 401 and generate an interaction force. Under the action of the force, the cleaning plate 504 compresses the spring 503 and moves in the direction of the support shaft 103.
[0047] The cross-section of the cleaning roller 4012 is serrated. When the cleaning plate 504 contacts the surface of the cleaning roller 4012, the cleaning roller 4012 is rotated by friction.
[0048] In some preferred embodiments, a vacuuming device 7 is fixed between the two sealing plates 110. The vacuuming device 7 is located between the water storage tank 111 and the primary cleaning roller 401 and is lower than the rotating shaft 4011. It is used to promptly suck up the debris and debris cleaned by the primary cleaning roller 401. The output end of the vacuuming device 7 faces the outer wall of the primary cleaning roller 401 and can be precisely aligned with the annular groove 4013 area of the cleaning roller 4012 to clean the sediment at the bottom of the annular groove 4013. Its input end is fixed with a collection box 701 through a sealed pipeline. The collection box 701 can be fixed on the outside of the sealing plate 110 or on the ground to centrally store the debris and debris sucked up by the vacuuming device 7 for subsequent unified cleaning and processing.
[0049] As the cleaning roller 4012 rotates, the sewage located between the support base 109 and the cleaning roller 4012 enters the water passage 4014 and flows out from the water passage 4014 under the action of gravity when it rotates above the dust collection device 7.
[0050] A residue collection box 505 is installed below the secondary cleaning roller 501. The residue collection box 505 is fixed to the sealing plate 110. One end of the residue collection box 505 passes through the sealing plate 110 and forms an opening. The residue collection box 505 is used to collect the garbage cleaned out of the secondary cleaning zone 5 and discharge it through the opening on the sealing plate 110.
[0051] In some preferred embodiments, two mounting plates 101 are fixed together on their side walls with a garbage bin 8. The garbage bin 8 is open at both ends and corresponds to the dumping area 3. It is located on the path of garbage dumping and is used to receive the garbage dumped by the hook 108 in the dumping area 3. A conveyor belt 9 is provided at the bottom of the garbage bin 8. The conveyor belt 9 is used to guide the garbage and transport the garbage collected in the garbage bin 8 to a designated location, so as to realize the automated transfer of garbage and reduce the intensity of manual cleaning.
[0052] In some preferred embodiments, a partition 801 is fixed to the side of the trash can 8 near the primary cleaning roller 401. The partition 801 is attached to the outer wall of the primary cleaning roller 401 to prevent trash from falling into the water passage hole 4014.
[0053] The water storage tank 111 is connected to a sedimentation tank 10 via a pipe. The sedimentation tank 10 is used to separate mud and water in the sewage. A biological reaction tank 11 is fixed on one side of the sedimentation tank 10. The water in the sedimentation tank 10 overflows into the biological reaction tank 11. The biological reaction tank 11 is used to remove inorganic substances such as nitrogen and phosphorus from the water.
[0054] Working principle: Sewage introduction and preliminary filtration: Sewage enters the closed water flow channel formed by the sealing plate 110, support base 109, mounting plate 101 and water storage tank 111 from the inlet of the water storage tank 111.
[0055] The hook 108 on the connecting plate 107 is located in the sewage in the lifting zone 2. As it moves with the support shaft 103, the hook 108 hangs up and lifts up the garbage such as plastic bags and branches in the water, thus achieving preliminary filtration of the sewage and preventing larger garbage from entering the subsequent treatment stage.
[0056] Garbage dumping: When the garbage on the hook 108 moves to the dumping area 3 along with the connecting plate 107, the dumping area 3 has a 90° bent structure. After the hook 108 enters the dumping area 3, it gradually becomes horizontal. Then, after bending and turning, it becomes inverted. Under the action of gravity, the garbage hooked on the hook 108 is successfully released from the hook 108 and falls into the garbage bin 8 located on the path of the dumping area 3, realizing the centralized collection of garbage.
[0057] First-level cleaning: When the connecting plate 107 drives the hook 108 to continue moving to the first-level cleaning area 4, the hook 108 passes through the first-level cleaning roller 401 and is embedded in the annular groove 4013. The cleaning roller 4012 rotates synchronously with the movement of the hook 108 to accurately clean the garbage remaining on the surface of the hook 108, improve the effect of the first-level cleaning, and ensure that there are no dead corners in the cleaning.
[0058] Secondary cleaning: When the connecting plate 107 moves the hook 108 to the secondary cleaning zone 5, the hook 108 passes through the secondary cleaning roller 501 and is embedded in the annular groove 4013. During the rotation of the secondary cleaning roller 501, the cleaning plate 504 comes into contact with the surface of the primary cleaning roller 401 and generates an interaction force. Under the action of the force, the cleaning plate 504 compresses the spring 503 and moves towards the support shaft 103, cleaning the hook 108 that has passed through the secondary cleaning roller 501 to ensure the cleanliness of the hook 108 and guarantee the subsequent hooking effect.
[0059] By rotating the primary cleaning roller 401, the sewage contains easily sedimentable impurities such as mud and sand, which settle at the bottom between the primary cleaning roller 401 and the guide plate 112 and enter the sludge pressing channel. Since the width of the annular groove 4013 is relatively narrow, the sedimentation structure in the sludge pressing channel is relatively stable and moves towards the secondary cleaning zone 5 along with the primary cleaning roller 401.
[0060] After moving to the vacuuming device 7, the vacuuming device 7 sucks away the sediment at the bottom of the annular groove 4013. The sucked-in debris enters the collection box 701 through a sealed pipe for centralized storage, facilitating subsequent unified cleaning and treatment. At the same time, the wastewater located between the support base 109 and the cleaning roller 4012 enters the water passage 4014 and flows out from the water passage 4014 under the action of gravity when it rotates above the vacuuming device 7 with the cleaning roller 4012.
[0061] The garbage collected in the secondary cleaning zone 5 falls into the residue collection box 505 and is discharged through the opening on the sealing plate 110, so as to achieve further collection and processing of the garbage.
[0062] Waste transfer: The conveyor belt 9 at the bottom of the waste bin 8 is activated to transport the waste collected in the waste bin 8 to the designated location, realizing automated waste transfer and reducing the intensity of manual cleaning.
[0063] Wastewater post-treatment: The storage tank 111 is connected to the sedimentation tank 10 through a pipeline. After preliminary filtration and garbage removal, the wastewater enters the sedimentation tank 10. The sedimentation tank 10 separates the mud and water in the wastewater, causing impurities such as mud and sand to settle at the bottom of the tank.
[0064] Biological reaction treatment: A biological reaction tank 11 is fixed on one side of the sedimentation tank 10.
