Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment device that utilizes renewable energy. Background Technology

[0002] With the acceleration of urbanization and the concentration of population in cities, the discharge of domestic sewage has increased significantly. For example, a medium-sized city can generate hundreds of thousands of tons of domestic sewage every day, which contains a large amount of solid impurities. Wastewater generated during industrial production also contains a large amount of solid impurities. Therefore, solid-liquid separation is required as a preliminary treatment before advanced treatment.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220834341U, which discloses a wastewater treatment device utilizing renewable energy. The device includes an inlet and a power assembly disposed on one side of the inlet. The power assembly includes a power fan blade, a rotating cone, an input gear, an output gear, a transmission rod, a stabilizing plate, a column, a filter chamber, a filter plate, and a reciprocating lead screw.

[0004] The aforementioned device requires the external sewage supply to be stopped when discharging impurities, making it unable to operate continuously. Furthermore, the impurities have low fluidity and are difficult to flow out of the sewage outlet on their own, making cleaning inconvenient. Adding external water flow to flush them would increase the wetness of the impurities, leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment device that utilizes renewable energy to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device utilizing renewable energy, comprising a treatment tank, a separation component at the top of the treatment tank, the separation component including a mounting frame slidably connected to the top of the treatment tank, an arc-shaped metal filter screen fixedly connected to the mounting frame, a scraper rotatably connected inside the mounting frame, one bottom end of the scraper contacting the top outer wall of the metal filter screen, two connecting claws fixedly connected to the outside of the scraper's rotating shaft, a common sealing plate fixedly connected between the two connecting claws, the centers of the sealing plate and the metal filter screen coinciding with the axis of the scraper's rotating shaft, a support frame fixedly connected to one end of the mounting frame, a temporary storage hopper fixedly connected to the top end of the support frame, the sealing plate contacting the bottom opening of the temporary storage hopper, a driving structure fixedly connected to the other end of the mounting frame, a deodorization box fixedly connected to one side of the treatment tank's outer wall, an inlet opening on one side of the deodorization box's outer wall, the end of the mounting frame near the deodorization box extending into the inlet, and two symmetrically arranged deodorization components fixedly connected to the outside of the deodorization box.

[0007] This device can quickly remove solid impurities from the surface of a metal filter screen without interrupting the water supply. The cleaning process is convenient and quick, which improves the practicality of the device. After running for a period of time, the telescopic electric cylinder is turned on to retract. The telescopic electric cylinder drives the drive rod to slide along the guide rail. The drive rod drives one end of the extension wall to rotate. The extension wall drives the scraper and connecting claw to rotate synchronously. The scraper can then push the solid impurities from one side of the metal filter screen. Before the scraper comes into contact with the sewage flow, the sealing plate can block the bottom opening of the temporary storage hopper. The sewage will be temporarily stored in the temporary storage hopper. As the scraper moves, the sealing plate will always keep the bottom opening of the temporary storage hopper blocked. This way, there is no need to stop the external sewage supply, and the sewage can be prevented from affecting the discharge of impurities.

[0008] As a further preferred embodiment of this technical solution, the driving structure includes a guide rail fixedly connected to the outer wall of the other end of the mounting frame. The guide rail is T-shaped. A vertically arranged driving rod is slidably connected to the outside of the guide rail. One end of the scraper rotation shaft is fixedly connected to an L-shaped extension wall. A vertical groove is opened at the top of the driving rod. The vertical groove is slidably sleeved on the outside of the bottom end of the extension wall. A horizontally arranged telescopic electric cylinder is fixedly connected to the other end of the mounting frame. The output end of the telescopic electric cylinder is fixedly connected to the bottom end of the driving rod.

[0009] As a further preferred embodiment of this technical solution, the deodorization component includes a negative pressure fan fixedly connected to the upper part of the outer wall of one end of the deodorization box. The air inlet of the negative pressure fan is located inside the deodorization box. A pipe is fixedly connected to the outside of the air outlet of the negative pressure fan. An installation cover is fixedly connected to the outer wall of the other end of the deodorization box. The pipe is connected to the installation cover. A mesh frame is slidably connected inside the installation cover. The end cap of the mesh frame is fixedly connected to the installation cover by bolts. Activated carbon particles are filled inside the mesh frame. A reinforcing structure is fixedly connected to the outside of the installation cover.

[0010] The pushed-down impurities fall into the trolley inside the deodorization box. After the solid impurities are separated from the sewage and accumulate together, microorganisms will multiply in large numbers and produce a strong odor. Turning on a negative pressure fan on the side of the deodorization box will draw the air inside the deodorization box outward, while external air and air above the metal filter screen will be continuously drawn in. This air will enter the installation cover through the pipe and be adsorbed by the activated carbon filled inside the mesh frame before flowing out, effectively preventing the odor from affecting the working environment.

[0011] As a further preferred embodiment of this technical solution, the reinforcing structure includes a second pipe fixedly connected to the outer wall of one side of the mounting cover, the second pipe being connected to the mounting cover, a horizontally arranged nozzle fixedly connected to the outer wall of one side of the treatment box, the outlet of the nozzle being oriented towards the inlet of the deodorizing box, one bottom end of the second pipe being connected to the nozzle, and a valve fixedly connected inside the second pipe.

[0012] As a further preferred embodiment of this technical solution, a mounting frame is fixedly connected to the outside of the processing box, and a plurality of photovoltaic panels distributed at equal intervals are fixedly connected to the top of the mounting frame. A collection component is fixedly connected to the outside of the processing box.

[0013] As a further preferred embodiment of this technical solution, the collecting component includes a battery fixedly connected to the outer wall of one end of the processing box, several photovoltaic panels are electrically connected to the battery via wires, and the battery is electrically connected to a telescopic cylinder and two negative pressure fans via wires.

[0014] As a further preferred embodiment of this technical solution, a rubber gasket is provided on the top outer wall of the sealing plate.

[0015] This utility model provides a wastewater treatment device that utilizes renewable energy, and has the following beneficial effects: (1) By setting a separation component, this utility model can quickly clean the solid impurities on the surface of the metal filter screen without stopping the water supply. The cleaning process is convenient and quick, which is conducive to improving the practicality of the device. After running for a period of time, turn on the switch of the telescopic electric cylinder to make it retract. The telescopic electric cylinder drives the drive rod to slide along the guide rail. The drive rod drives one end of the extension wall to start to flip. The extension wall drives the scraper and connecting claw to flip synchronously. The scraper can push the solid impurities from one side of the metal filter screen. Before the scraper comes into contact with the sewage flow, the sealing plate can block the bottom opening of the temporary storage hopper. The sewage will be temporarily stored in the temporary storage hopper. As the scraper moves, the sealing plate will always block the bottom opening of the temporary storage hopper. In this way, there is no need to stop the external sewage supply and the sewage can be prevented from affecting the discharge of impurities.

[0016] (2) By setting up a deodorization component, the impurities pushed down will fall into the inside of the deodorization box. After the solid impurities are separated from the sewage and piled up together, microorganisms will multiply in large quantities and produce a strong odor. When a negative pressure fan on the side of the deodorization box is turned on, the air inside the deodorization box is drawn outward, and the outside air and the air above the metal filter screen are continuously drawn in. As soon as this air enters the installation cover through the pipe, it will be adsorbed by the activated carbon filled inside the mesh frame before flowing out, effectively preventing the odor from affecting the working environment.

[0018] 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.

[0019] This utility model provides a technical solution: such as Figure 2 , Figure 3 As shown in Figure 4, in this embodiment, a wastewater treatment device utilizing renewable energy includes a treatment tank 1. A separation component 5 is provided on the top of the treatment tank 1. The separation component 5 includes a mounting frame 501 slidably connected to the top of the treatment tank 1. An arc-shaped metal filter screen 502 is fixedly connected to the mounting frame 501. A scraper 503 is rotatably connected inside the mounting frame 501. One bottom end of the scraper 503 contacts the top outer wall of the metal filter screen 502. Two connecting claws 504 are fixedly connected to the outside of the rotating shaft of the scraper 503. A single sealing plate 5 is fixedly connected between the two connecting claws 504. 05. The centers of the sealing plate 505 and the metal filter screen 502 are both aligned with the axis of the scraper 503. A support frame is fixedly connected to the outer wall of one end of the mounting frame 501. A temporary storage hopper 506 is fixedly connected to the top end of the support frame. The sealing plate 505 contacts the bottom opening of the temporary storage hopper 506. A drive structure is fixedly connected to the outer wall of the other end of the mounting frame 501. A deodorizing box 4 is fixedly connected to the outer wall of one side of the treatment box 1. An inlet is opened on the outer wall of one side of the deodorizing box 4. The end of the mounting frame 501 near the deodorizing box 4 extends into the inlet. Two symmetrically arranged deodorizing components 6 are fixedly connected to the outside of the deodorizing box 4.

[0020] External sewage flows into the temporary storage hopper 506, then falls down through the outlet at its bottom, and then falls onto the top of the metal filter screen 502 for filtration. Solid impurities are intercepted at the top of the metal filter screen 502, while the remaining sewage passes through the mesh and falls into the treatment tank 1, and then flows to the external sewage treatment pond for further treatment.

[0021] The drive structure includes a guide rail 510 fixedly connected to the outer wall of the other end of the mounting frame 501. The guide rail 510 is T-shaped. A vertically arranged drive rod 509 is slidably connected to the outside of the guide rail 510. One end of the rotating shaft of the scraper 503 is fixedly connected to an L-shaped extension wall 507. A vertical groove is opened at the top of the drive rod 509. The vertical groove is slidably sleeved on the outside of the bottom end of the extension wall 507. A horizontally arranged telescopic electric cylinder 508 is fixedly connected to the other end of the mounting frame 501. The output end of the telescopic electric cylinder 508 is fixedly connected to the bottom end of the drive rod 509.

[0022] After running for a period of time, turn on the switch of the telescopic electric cylinder 508 to make it retract. The telescopic electric cylinder 508 drives the drive rod 509 to slide along the guide rail 510. The drive rod 509 drives one end of the extension wall 507 to start to flip. The extension wall 507 drives the scraper 503 and the connecting claw 504 to flip synchronously. The scraper 503 can push solid impurities from one side of the metal filter screen 502. Before the scraper 503 comes into contact with the sewage flow, the sealing plate 505 can block the bottom opening of the temporary storage hopper 506. The sewage will be temporarily stored in the temporary storage hopper 506. As the scraper 503 moves, the sealing plate 505 will always block the bottom opening of the temporary storage hopper 506. In this way, there is no need to stop the external sewage supply and the sewage can be prevented from affecting the discharge of impurities.

[0023] like Figure 1 As shown in Figure 2, the deodorization component 6 includes a negative pressure fan 601 fixedly connected to the upper part of the outer wall of one end of the deodorization box 4. The air inlet of the negative pressure fan 601 is located inside the deodorization box 4, and a pipe 602 is fixedly connected to the outside of the air outlet of the negative pressure fan 601. A mounting cover 603 is fixedly connected to the outer wall of the other end of the deodorization box 4. The pipe 602 is connected to the mounting cover 603. A mesh frame 604 is slidably connected inside the mounting cover 603. The end cap of the mesh frame 604 is fixedly connected to the mounting cover 603 by bolts. The mesh frame 604 is filled with activated carbon particles. A reinforcing structure is fixedly connected to the outside of the mounting cover 603.

[0024] The reinforced structure includes a second pipe 605 fixedly connected to the outer wall of one side of the mounting cover 603. The second pipe 605 is connected to the mounting cover 603. A horizontally arranged nozzle 606 is fixedly connected to the outer wall of one side of the treatment box 1. The outlet of the nozzle 606 is set towards the inlet of the deodorizing box 4. One end of the bottom of the second pipe 605 is connected to the nozzle 606. A valve is fixedly connected inside the second pipe 605.

[0025] The pushed-down impurities fall into the inner trolley of the deodorization box 4. After the solid impurities are separated from the sewage and accumulate together, microorganisms will multiply in large quantities and produce a strong odor. Turn on a negative pressure fan 601 on the side of the deodorization box 4, and the air inside the deodorization box 4 will be drawn out. The outside air and the air above the metal filter screen 502 will be continuously drawn in. This air will enter the mounting cover 603 through the first pipe 602. After being adsorbed by the activated carbon filled inside the mesh frame 604, it will flow out, effectively preventing the odor from affecting the working environment. When the activated carbon inside one of the mesh frames 604 loses its effectiveness, first close the valve on the same side and open the valve on the other side, and start another negative pressure fan 601 to achieve continuous deodorization. The two deodorization components 6 are used alternately, which can effectively prevent the odor from overflowing. The air entering the second pipe 605 then enters the nozzle 606 and is then shot outward through the outlet of the nozzle 606. The shot airflow can blow the air above the metal filter screen 502 toward the opening of the deodorization box 4, which can further suppress the diffusion of odor.

[0026] like Figure 1 As shown in Figure 2, a mounting frame 2 is fixedly connected to the outside of the processing box 1, and several photovoltaic panels 3 are fixedly connected to the top of the mounting frame 2 at equal intervals. A collection component is fixedly connected to the outside of the processing box 1.

[0027] The collection unit includes a battery fixedly connected to the outer wall of one end of the processing box 1, several photovoltaic panels 3 are electrically connected to the battery through wires, and the battery is electrically connected to the telescopic cylinder 508 and two negative pressure fans 601 through wires. The photovoltaic panels 3 convert solar energy into electrical energy and store it in the battery to power the telescopic cylinder 508 and the negative pressure fans 601.

[0028] like Figure 3 As shown, a rubber gasket is provided on the top outer wall of the sealing plate 505. The rubber gasket can reduce the gap between the sealing plate 505 and the outlet of the temporary storage hopper 506, thereby ensuring a better sealing effect.

[0029] This utility model provides a wastewater treatment device that utilizes renewable energy, and its specific working principle is as follows: When the device is working, external sewage flows into the temporary storage hopper 506, then falls downwards through the outlet at its bottom, and then falls onto the top of the metal filter screen 502 for filtration. Solid impurities are intercepted at the top of the metal filter screen 502, while the remaining sewage passes through the mesh and falls into the treatment tank 1, and then flows to the external sewage treatment pond for further treatment. After running for a period of time, the switch of the telescopic electric cylinder 508 is turned on to make it retract. The telescopic electric cylinder 508 drives the drive rod 509 to slide along the guide rail 510. The drive rod 509 drives one end of the extension wall 507 to start to rotate. The extension wall 507 drives the scraper 503 and the connecting claw 504 to rotate synchronously. The scraper 503 can then be removed from the metal filter screen. Solid impurities are pushed away from one side of the filter screen 502. Before the scraper 503 comes into contact with the sewage flow, the sealing plate 505 can block the bottom opening of the temporary storage hopper 506. The sewage will be temporarily stored in the temporary storage hopper 506. As the scraper 503 moves, the sealing plate 505 will always keep the bottom opening of the temporary storage hopper 506 blocked. This way, there is no need to stop the external sewage supply, and the sewage can be prevented from affecting the discharge of impurities. Finally, the telescopic electric cylinder 508 drives the drive rod 509 back to its original position, and the sewage treatment can continue. It should be noted that the flow rate of the outlet of the temporary storage hopper 506 is greater than the inlet flow rate of the external sewage to ensure that the sewage temporarily stored in the temporary storage hopper 506 can be discharged in time for the next operation.

[0030] The pushed-down impurities fall into the inner trolley of the deodorization box 4. After the solid impurities are separated from the sewage and accumulate together, microorganisms will multiply in large quantities and produce a strong odor. Turn on a negative pressure fan 601 on the side of the deodorization box 4, and the air inside the deodorization box 4 will be drawn out. The outside air and the air above the metal filter screen 502 will be continuously drawn in. This air will enter the mounting cover 603 through the first pipe 602. After being adsorbed by the activated carbon filled inside the mesh frame 604, it will flow out, effectively preventing the odor from affecting the working environment. When the activated carbon inside one of the mesh frames 604 loses its effectiveness, first close the valve on the same side and open the valve on the other side, and start another negative pressure fan 601 to achieve continuous deodorization. The two deodorization components 6 are used alternately, which can effectively prevent the odor from overflowing. The air entering the second pipe 605 then enters the nozzle 606 and is then shot outward through the outlet of the nozzle 606. The shot airflow can blow the air above the metal filter screen 502 toward the opening of the deodorization box 4, which can further suppress the diffusion of odor.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
