Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to a mobile integrated nano-aeration wastewater treatment device. Background Technology

[0002] A nano aerator is a wastewater treatment device that uses a water pump to draw wastewater into a nano aerator head and an air pump to inject air into the aerator head. High-pressure nanobubbles are formed in the mixing chamber through the Venturi effect or swirling shear, and then sprayed into the water. These bubbles diffuse in the water, increasing dissolved oxygen levels and enhancing the activity of aerobic microorganisms. This decomposes organic matter, inhibits algae growth, and improves water transparency, effectively improving water quality. To expand the scope of water treatment, nano aerators are currently typically installed on a floating platform. A traction device can move the floating platform and the nano aerator as a whole to change the aeration position.

[0003] When the water pump delivers water to the nano-aerator, the extremely small pore size of the nano-aerator allows impurities such as silt, organic debris, and microbial films in the water to easily penetrate into the nano-aerator. These impurities can accelerate the clogging of the nano-aerator's pores, causing a decrease in aeration efficiency. Existing solutions rely on manual disassembly and cleaning of the nano-aerator or chemical soaking after shutdown, which is time-consuming. In addition, frequent interruptions to the aeration process also lead to a decrease in wastewater treatment capacity. Although some equipment is now equipped with a filtration structure to prevent impurities from clogging the nano-aerator, these filtration structures still require regular manual cleaning and maintenance, which still affects the overall wastewater treatment efficiency. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mobile integrated nano-aeration wastewater treatment device to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: a mobile integrated nano-aeration sewage treatment device, comprising a float plate, a nano-aeration head and a guide pipe, wherein an equipment box is fixedly installed on the top of the float plate, and a water pump and an air pump are installed inside the equipment box, the nano-aeration head is connected to the output end of the air pump through an air supply pipe, the nano-aeration head is connected to the output end of the water pump through a water supply pipe, and the input end of the water pump is connected to a connecting pipe.

[0006] An anti-clogging mechanism is installed between the guide pipe and the connecting pipe. The anti-clogging mechanism includes a filter component, a power storage component, and a discharge component. The filter component is used to filter impurities in the water to prevent the nano-aeration head from clogging and to convert the kinetic energy of the water. The power storage component is used to absorb the converted energy when the water level in the filter component reaches a preset value and to pull the discharge component to move. The discharge component is used to output the impurities intercepted by the filter component to the outside when the water level in the filter component reaches a preset value.

[0007] Preferably, the filter assembly includes an upper shell, a lower shell, and a filter cartridge. Both the upper and lower shells are fixedly installed on the surface of the equipment housing. The top of the upper shell is fixedly connected to the guide pipe, and the bottom of the filter cartridge is rotatably connected to the bottom of the inner cavity of the lower shell. A drain nozzle is fixedly connected to the bottom of the filter cartridge. The bottom end of the drain nozzle passes through the bottom of the lower shell and extends downward.

[0009] Preferably, the energy storage component includes a rotating ring, the upper and lower cylinder shells are rotatably connected by the rotating ring, an extension ring is fixedly connected to the inner side of the rotating ring, and a spring and traction components are also provided on the rotating ring.

[0010] Preferably, the bottom of the extension ring is provided with a groove segment and a flat segment, and a trigger surface is provided at the separation between the groove segment and the flat segment.

[0011] Preferably, the traction component includes a rotating shaft, a pawl, and a compression spring. The rotating shaft is fixedly mounted on the rotating ring, and the pawl is rotatably mounted on the surface of the rotating shaft. The elastic force of the compression spring drives the pawl to move away from the rotating ring around the axis of the rotating shaft.

[0012] Preferably, the discharge assembly includes a receiving ring and a sealing component. The receiving ring is rotatably mounted on the upper cylinder shell. A ratchet is provided on the inner side of the receiving ring, and a positioning surface is provided on the ratchet. A guide plate is provided at the bottom of the receiving ring, and multiple sets of guide plates are evenly arranged.

[0013] Preferably, two sets of sealing components are symmetrically arranged. The sealing components include a sealing plate, a sliding rod, and a stabilizing block.

The stabilizing block is fixedly installed on the outer surface of the lower cylinder shell. The bottom end of the sliding rod is fixedly connected to the fixing block. The surface of the sliding rod is slidably connected to the inside of the stabilizing block.

[0014] Preferably, a positioning spring is fitted on the surface of the sliding rod. The elastic force of the positioning spring drives the sealing plate to move upward and seal the sewage outlet. The two sealing plates are fixedly connected by a connecting rod.

[0016] The beneficial effects of this invention are: This invention features a three-tiered mechanism: a filtration component to intercept impurities, an energy storage component to convert energy, and a discharge component to periodically discharge wastewater. Before water enters the nano-aeration head, the filter cartridge effectively filters and intercepts impurities in the water within the lower shell, preventing blockage and avoiding frequent shutdowns for cleaning. Furthermore, when the water level in the lower shell rises to a preset value (indicating that impurities have accumulated and affected filtration efficiency), the stored energy is automatically released, driving the receiving ring to rotate. Guided by a three-stage trajectory of the guide plate, the opening and closing of the sealing plate is precisely controlled, flushing impurities from the lower shell out along with the water. This achieves on-demand wastewater discharge without manual intervention, ensuring the filter cartridge maintains extremely high filtration efficiency and improving wastewater treatment efficiency.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1-Figure 4 This invention provides a mobile integrated nano-aeration wastewater treatment device, including a float plate 1, nano-aeration heads 3, and a guide pipe 6. An equipment housing 2 is fixedly installed on the top of the float plate 1. A water pump and an air pump are installed inside the equipment housing 2. The nano-aeration heads 3 are connected to the output end of the air pump through an air supply pipe 4, and the nano-aeration heads 3 are connected to the output end of the water pump through a water supply pipe 5. A connecting pipe 8 is connected to the input end of the water pump. The float plate 1 floats on the water surface. A traction device (such as a ship) can move the entire device by traction of the float plate 1 to change the aeration position. The above is the prior art in the field of nano-aerators and will not be described in detail here.

[0033] An anti-clogging mechanism 7 is provided between the guide pipe 6 and the connecting pipe 8. The anti-clogging mechanism 7 includes a filter component 71, a power storage component 72, and a discharge component 73. The filter component 71 is used to filter impurities in the water to prevent the nano aeration head 3 from clogging and to convert the kinetic energy of the water. The power storage component 72 is used to absorb the converted energy when the water level in the filter component 71 reaches a preset value and to pull the discharge component 73 to move. The discharge component 73 is used to output the impurities intercepted by the filter component 71 to the outside when the water level in the filter component 71 reaches a preset value.

[0034] Reference Figures 1-6 The filter assembly 71 includes an upper cylindrical shell 711, a lower cylindrical shell 712, and a filter cylinder 713. The upper cylindrical shell 711 and the lower cylindrical shell 712 are both fixedly installed on the surface of the equipment housing 2. The top of the upper cylindrical shell 711 is fixedly connected to the guide pipe 6. The bottom of the filter cylinder 713 is rotatably connected to the bottom of the inner cavity of the lower cylindrical shell 712. A drain nozzle 718 is fixedly connected to the bottom of the filter cylinder 713. The bottom end of the drain nozzle 718 passes through the bottom of the lower cylindrical shell 712 and extends downward. The bottom end of the drain nozzle 718 is rotatably connected to the connecting pipe 8. A drain port 719 is provided through the bottom of the lower cylindrical shell 712.

[0035] Furthermore, a rotating shaft 714 is fixedly connected to the top of the filter cylinder 713, an impeller 715 is fixedly connected to the top of the rotating shaft 714, a through-hole frame 716 is fixedly connected to the outer surface of the filter cylinder 713, and a float ball 717 that can float on the water surface is installed inside the through-hole frame 716.

[0036] During use, under the action of the air pump, air passes through the air supply pipe 4 and enters the nano aeration head 3. Under the action of the water pump, sewage passes through the guide pipe 6, the anti-clogging mechanism 7, the connecting pipe 8 and the water supply pipe 5 in sequence and enters the nano aeration head 3. The air and water mix to form nano bubbles. The nano aeration head 3 sprays the nano bubbles into the water. These bubbles diffuse in the water, increase the dissolved oxygen content of the water, enhance the activity of aerobic microorganisms, thereby decompose organic matter, inhibit algae growth, optimize water transparency, and effectively improve water quality. During the process of sewage entering the anti-clogging mechanism 7 through the guide pipe 6, the water first passes through the impeller 715. Under the impact of the water, the kinetic energy of the water is gradually converted into mechanical energy that makes the impeller 715 rotate. This causes the impeller 715, the rotating shaft 714, the filter cylinder 713, the drain nozzle 718, and the through hole frame 716 to rotate clockwise around the axis of the rotating shaft 714. Then the water enters the lower cylinder shell 712. Impurities in the water cannot pass through the holes on the filter cylinder 713 and are intercepted in the lower cylinder shell 712. The water passes through the holes on the filter cylinder 713 and enters the connecting pipe 8 through the drain nozzle 718, and finally enters the nano aeration head 3. When there are few impurities accumulated in the lower cylinder shell 712, water can quickly pass through the holes on the filter cylinder 713 and enter the drain nozzle 718. The water level in the lower cylinder shell 712 remains low. As time goes by, more and more impurities accumulate in the lower cylinder shell 712, and the water level in the lower cylinder shell 712 gradually increases. When the water level is level with the float ball 717, the float ball 717 rises synchronously with the rise in water level.

[0037] In summary, wastewater flows into the upper shell 711 through the guide pipe 6 and enters the lower shell 712 under gravity. The filter cartridge 713, as the core filter element, has precision pores on its surface that allow water to flow through and eventually to the drain nozzle 718 and connecting pipe 8. This effectively intercepts impurities in the water, such as silt, organic debris, and microbial films, that are larger than the pore size. These impurities are trapped in the inner cavity of the lower shell 712, thus protecting the downstream nano-aeration head 3 from clogging and avoiding frequent shutdowns for cleaning the nano-aeration head 3. Furthermore, the impeller 715 is cleverly driven to rotate by the impact force of the water flow, converting the kinetic energy of the water flow into the mechanical energy of the continuously rotating filter cartridge 713. This rotation process not only helps prevent impurities from caking on the surface of the filter cartridge 713 and maintaining its filtration efficiency, but also drives the float 717 inside the through-hole frame 716 to move synchronously. As a water level sensing unit, the rising height of the float 717 accurately reflects the water level in the lower shell 712 caused by the accumulation of impurities, providing a key trigger signal for subsequent automatic sewage discharge.

[0038] Preferably, a metal wire mesh is installed at the inlet end of the guide pipe 6. The metal wire mesh serves as the first physical barrier, which can effectively intercept large debris in the water (such as leaves, plastic fragments, aquatic plants, and fibers), preventing these large debris from impacting or entangling the impeller 715 after entering the guide pipe 6. It also significantly reduces the burden on the filter cartridge 713 in the downstream filter assembly 71, reduces the risk of it being quickly blocked, and extends its automatic sewage discharge cycle.

[0039] Reference Figures 1-12 The power storage component 72 includes a rotating ring 721. The upper cylinder shell 711 and the lower cylinder shell 712 are rotatably connected through the rotating ring 721. An extension ring 722 is fixedly connected to the inner side of the rotating ring 721. The rotating ring 721 is also provided with a spring 723 and a traction component 724. Multiple sets of traction components 724 are provided, and the multiple sets of traction components 724 are arranged in an array around the circumference of the rotating ring 721.

[0040] Furthermore, the bottom of the extension ring 722 is provided with a groove segment 7221 and a flat segment 7222, and a trigger surface 7223 is provided at the separation between the groove segment 7221 and the flat segment 7222.

[0041] Furthermore, the traction component 724 includes a rotating shaft 7241, a pawl 7242, and a compression spring 7243. The rotating shaft 7241 is fixedly mounted on the rotating ring 721, and the pawl 7242 is rotatably mounted on the surface of the rotating shaft 7241. The elastic force of the compression spring 7243 drives the pawl 7242 to move away from the rotating ring 721 around the axis of the rotating shaft 7241.

[0042] The discharge assembly 73 includes a receiving ring 731 and a sealing component 734. The receiving ring 731 is rotatably mounted on the upper cylinder shell 711. A ratchet 732 is provided on the inner side of the receiving ring 731. A positioning surface 7321 is provided on the ratchet 732. A guide plate 733 is provided at the bottom of the receiving ring 731. Multiple sets of guide plates 733 are evenly arranged.

[0043] Furthermore, two sets of sealing components 734 are symmetrically arranged. The sealing components 734 include a sealing plate 7341, a sliding rod 7343, and a stabilizing block 7345. The sealing plate 7341 matches the drain outlet 719. A fixing block 7342 is fixedly connected to the bottom of the sealing plate 7341. The stabilizing block 7345 is fixedly installed on the outer surface of the lower cylinder shell 712. The bottom end of the sliding rod 7343 is fixedly connected to the fixing block 7342. The surface of the sliding rod 7343 is slidably connected to the inside of the stabilizing block 7345.

[0044] Furthermore, a positioning spring 7346 is fitted on the surface of the sliding rod 7343. The elastic force of the positioning spring 7346 drives the sealing plate 7341 to move upward and seal the drain port 719. The two sealing plates 7341 are fixedly connected by a connecting rod 735. A roller 7344 is rotatably installed at the top of the sliding rod 7343. The bottom of the guide plate 733 is provided with a pressing section 7331, a holding section 7332 and a reset section 7333. The roller 7344 can roll along the pressing section 7331, the holding section 7332 and the reset section 7333.

[0045] During use, when the water level inside the lower cylinder shell 712 reaches the preset value (indicating that impurities have accumulated and affected the filtration efficiency), the float 717 enters the groove section 7221. Due to the limiting effect of the through-hole frame 716, the float 717 cannot detach from the through-hole frame 716. As the through-hole frame 716 rotates clockwise around the axis of rotation 714, the float 717 rotates clockwise synchronously along the groove section 7221. During this process, the rotating ring 721 and the extension ring 722 remain stationary. When the float 717... When the float 717 moves to the trigger surface 7223, it abuts against the trigger surface 7223. Under the push of the float 717, the rotating ring 721 and the extension ring 722 rotate clockwise synchronously. During the rotation of the rotating ring 721, the mainspring 723 gradually tightens and the elastic force increases. The pawl 7242 moves between the ratchet teeth 732. The compression spring 7243 continuously tightens and extends. The pawl 7242 cannot pull the excretion assembly 73 to move, and the excretion assembly 73 remains stationary. When the mainspring 723 is tightened, the float 717 can no longer push the rotating ring 721 to rotate. At this time, under the pressure of the trigger surface 7223, the height of the float 717 decreases and retracts into the through hole frame 716. Then, with the rotation of the through hole frame 716, the float 717 moves along the planar section 7222. During this process, the elasticity of the mainspring 723 is released and drives the rotating ring 721 and the extension ring 722 to rotate counterclockwise as a whole. The rotating ring 721 rotates and drives the pawl 7242 to rotate counterclockwise synchronously. The pawl 7242 abuts against the positioning surface 7321. Under the push of the pawl 7242, the receiving ring 731 rotates counterclockwise synchronously. During the counterclockwise rotation of the receiving ring 731, the roller 7344 first rolls along the pressing section 7331. During this process, the roller 7344 and the sliding rod 7343 move downwards as a whole. The positioning spring 7346 gradually tightens and its elastic force increases. The sliding rod 7343 moves and drives the sealing plate 7341 downwards synchronously via the fixing block 7342. The sealing plate 7341 gradually releases the blockage on the drain outlet 719. After the roller 7344 leaves the pressing section 7331, it enters the holding section 7332. As the roller 7344 moves along the holding section 7332... During the rolling process, the position of the sealing plate 7341 remains unchanged, the drain port 719 remains open, and impurities in the lower cylinder shell 712 are flushed out along with the water. When the roller 7344 leaves the holding section 7332, the roller 7344 enters the reset section 7333. As the roller 7344 rolls along the reset section 7333, the elastic force of the positioning spring 7346 is released and drives the sealing plate 7341 to move upward. When the sealing plate 7341 seals the drain port 719, the energy of the spring 723 is released, and the receiving ring 731 remains stationary and no longer rotates.

[0046] In summary, when the float 717 detects that the water level has reached the preset critical value (indicating that the accumulation of impurities has affected the filtration efficiency), its position change will precisely trigger the energy storage component 72. This triggering action drives the rotating ring 721 to rotate, converting part of the mechanical energy transmitted from the filter component 71 into the elastic potential energy of the spring 723 for storage, thus completing the energy preparation before sewage discharge. Once the triggering conditions are met, the stored energy is automatically released, precisely pulling the receiving ring 731 to rotate. The guide plate 733 at the bottom of the receiving ring 731 has a specific three-segment trajectory, which controls the movement of the roller 7344 of the sealing component 734, thereby precisely manipulating the sealing plate 7341. During the holding phase with the drain port 719 open, the impurities accumulated in the lower cylinder shell 712 are flushed out at high speed and in a concentrated manner under the action of the water pressure inside the lower cylinder shell 712, achieving thorough sewage discharge. After the sewage discharge is completed, the drain port 719 automatically and reliably closes (the kinetic energy of the water decreases after passing through the impeller 715, and it cannot overcome the positioning spring 7346 to directly open the sealing plate 7341). The system returns to the initial filtration state and waits for the next trigger. The entire process does not require manual intervention and is only executed automatically when the impurities accumulate to a critical point that affects the filtration efficiency, ensuring that the filter component 71 continues to operate efficiently.

[0047] The working principle of this invention is as follows: Under the action of the air pump, air passes through the air supply pipe 4 and enters the nano-aeration head 3. Under the action of the water pump, sewage passes through the guide pipe 6, the anti-clogging mechanism 7, the connecting pipe 8, and the water supply pipe 5 in sequence and enters the nano-aeration head 3. The air and water mix to form nano bubbles. The nano-aeration head 3 sprays the nano bubbles into the water. These bubbles diffuse in the water, increase the dissolved oxygen content of the water, enhance the activity of aerobic microorganisms, thereby decompose organic matter, inhibit algae growth, optimize water transparency, and effectively improve water quality.

[0048] During the process of sewage entering the anti-clogging mechanism 7 through the guide pipe 6, the water first passes through the impeller 715. Under the impact of the water, the kinetic energy of the water is gradually converted into mechanical energy that makes the impeller 715 rotate. This causes the impeller 715, the rotating shaft 714, the filter cylinder 713, the drain nozzle 718, and the through-hole frame 716 to rotate clockwise around the axis of the rotating shaft 714. After that, the water enters the lower cylinder shell 712. Impurities in the water cannot pass through the holes on the filter cylinder 713 and are intercepted in the lower cylinder shell 712. The water passes through the holes on the filter cylinder 713 and enters the connecting pipe 8 through the drain nozzle 718, and finally enters the nano aeration head 3.

[0049] When there are few impurities accumulated in the lower cylinder shell 712, water can quickly pass through the holes on the filter cylinder 713 and enter the drain nozzle 718. The water level in the lower cylinder shell 712 remains low. As time goes by, more and more impurities accumulate in the lower cylinder shell 712, and the water level in the lower cylinder shell 712 gradually increases. When the water level is level with the float ball 717, the float ball 717 rises synchronously with the rise in water level.

[0050] When the water level inside the lower cylinder shell 712 reaches the preset value (indicating that impurities have accumulated and affected filtration efficiency), the float 717 enters the groove section 7221. Due to the limiting effect of the through-hole bracket 716, the float 717 cannot detach from the through-hole bracket 716. As the through-hole bracket 716 rotates clockwise around the axis of rotation 714, the float 717 rotates clockwise synchronously along the groove section 7221. During this process, the rotating ring 721 and the extension ring 722 remain stationary. When the float 717 moves... When the float 717 moves to the trigger surface 7223, it comes into contact with the trigger surface 7223. Under the push of the float 717, the rotating ring 721 and the extension ring 722 rotate clockwise synchronously. During the rotation of the rotating ring 721, the mainspring 723 gradually tightens and the elasticity increases. The pawl 7242 moves between the ratchet teeth 732. The compression spring 7243 continuously tightens and extends. The pawl 7242 cannot pull the excretion assembly 73 to move, and the excretion assembly 73 remains stationary.

[0051] When the mainspring 723 is tightened, the float 717 can no longer push the rotating ring 721 to rotate. At this time, under the pressure of the trigger surface 7223, the height of the float 717 decreases and retracts into the through hole frame 716. Then, with the rotation of the through hole frame 716, the float 717 moves along the planar section 7222. During this process, the elasticity of the mainspring 723 is released and drives the rotating ring 721 and the extension ring 722 to rotate counterclockwise as a whole. The rotating ring 721 rotates and drives the pawl 7242 to rotate counterclockwise synchronously. The pawl 7242 abuts against the positioning surface 7321. Under the push of the pawl 7242, the receiving ring 731 rotates counterclockwise synchronously.

[0052] During the counterclockwise rotation of the receiving ring 731, the roller 7344 first rolls along the pressing section 7331. During this process, the roller 7344 and the sliding rod 7343 move downwards as a whole. The positioning spring 7346 gradually tightens and its elastic force increases. The sliding rod 7343 moves and drives the sealing plate 7341 downwards synchronously via the fixing block 7342. The sealing plate 7341 gradually releases the blockage on the drain outlet 719. After the roller 7344 leaves the pressing section 7331, it enters the holding section 7332. As the roller 7344 moves along the holding section 7332... During the rolling process, the position of the sealing plate 7341 remains unchanged, the drain port 719 remains open, and impurities in the lower cylinder shell 712 are flushed out along with the water. When the roller 7344 leaves the holding section 7332, the roller 7344 enters the reset section 7333. As the roller 7344 rolls along the reset section 7333, the elastic force of the positioning spring 7346 is released and drives the sealing plate 7341 to move upward. When the sealing plate 7341 seals the drain port 719, the energy of the spring 723 is released, and the receiving ring 731 remains stationary and no longer rotates.
