Description

Technical Field

[0001] This invention relates to the field of municipal wastewater purification technology, and more particularly to a municipal wastewater purification device. Background Technology

[0002] In municipal engineering, wastewater purification is essential. This requires wastewater purification and sedimentation to allow larger, heavy particles such as sand and gravel to settle before the purified wastewater is discharged, preventing pollution of the environment by wastewater that does not meet discharge standards.

[0003] Currently, after wastewater is purified and settled, a large amount of large heavy particles such as sand and gravel accumulate at the bottom of the grit chamber. In order to prevent these large heavy particles from affecting subsequent structures and installations, they need to be removed. The removal method is to close the inlet valve to stop wastewater from entering the grit chamber. After all the wastewater in the sedimentation tank is discharged, the particles in the grit chamber can be manually removed using a cleaning machine. This method is relatively troublesome, as it requires stopping the wastewater purification and sedimentation work, which affects the wastewater purification efficiency.

[0004] Therefore, there is a need to design a municipal wastewater purification device that can remove the precipitated particulate matter during wastewater purification and sedimentation, thereby improving the efficiency of wastewater purification. Summary of the Invention

[0005] To overcome the drawbacks of the cumbersome method of manually removing particulate matter from the sedimentation tank by closing the inlet valve to stop sewage from entering the sedimentation tank and discharging all sewage, which requires stopping the sewage purification and sedimentation process and affects the sewage purification efficiency, this invention provides a municipal sewage purification device that can remove the settled particulate matter during the sewage purification and sedimentation process, thereby improving the sewage purification efficiency.

[0006] This invention is achieved through the following technical means:

[0007] A municipal wastewater purification device includes a grit chamber and a housing mounted on the grit chamber. The bottom rear side of the grit chamber is inclined, and an inlet pipe is connected to the grit chamber. An annular plate is rotatably connected inside the housing. The annular plate has openings spaced apart to allow wastewater to pass through. A gear ring I is fixedly connected to the outer side of the annular plate. A servo motor is mounted on the housing, and a spur gear meshing with the gear ring I is fixedly connected to the end of the output shaft of the servo motor. The device also includes a U-shaped plate, a grid plate, an L-shaped rod, a guide ring, a trigger plate, a torsion spring, and a conveying assembly. The conveying assembly is mounted on the housing. The U-shaped plates are evenly spaced and fixed to the inner circumferential side of the annular plate. The U-shaped plates rotate... A grid plate is dynamically connected, forming a frame with a U-shaped plate. A torsion spring connects the rotating parts of the grid plate and the U-shaped plate. An L-shaped rod is fixedly fitted to the axial end of the grid plate. A guide ring is fixedly connected to the inner wall of the housing along the circumference. The inner wall of the guide ring contacts the end of the L-shaped rod. A trigger plate is fixedly connected to the guide ring. When the ring plate reverses, it drives the U-shaped plate to reverse, and the U-shaped plate reverses, which in turn drives the grid plate to reverse. The U-shaped plate and the grid plate work together to scoop up the particles at the bottom of the sedimentation tank and remove them. The L-shaped rod swings under the control of the trigger plate, causing the grid plate to swing and disengage from the particles. The particles fall onto the conveying assembly and are transported and collected.

[0008] To further explain, the trigger plate consists of an arc-shaped segment and two straight segments, wherein the two straight segments are fixed to the ends of the guide ring, and the arc-shaped segment is connected to the two straight segments.

[0009] To further explain, the bottom of the sedimentation tank is provided with an arc-shaped groove in the middle that is in reverse contact with the grid plate, so as to collect the purified sedimented particles.

[0010] Further explanation: The conveying assembly includes two mounting plates fixedly connected to the housing, and a conveyor is installed between the two mounting plates to move and convey the particles. A drive motor is mounted on one of the mounting plates, and the output shaft end of the drive motor is fixedly connected to the end of one of the conveyor wheels of the conveyor. A guide bucket is fixedly connected between the two mounting plates to guide the particles.

[0011] Further explanation includes a striking assembly, which includes fixed plates symmetrically fixed inside the housing. A rotating shaft is rotatably connected between the fixed plates. A striking rod is fixedly mounted on the rotating shaft for striking and vibrating the annular plate, thereby causing the grid plate to vibrate. A transmission assembly is provided between the annular plate and the rotating shaft for driving the rotating shaft to rotate.

[0012] To further explain, the adjacent striking rods are staggered, and the ends of the striking rods are made of rubber.

[0013] Further explanation: the transmission assembly includes a drive gear fixed to the end of the rotating shaft, and a gear ring II that meshes with the drive gear is fixed to the outer side of the annular plate to drive the drive gear to rotate.

[0014] Further explanation includes observation windows that are symmetrically fixed and inserted into the housing.

[0015] The significant advancement of this invention lies in:

[0016] 1. Wastewater is discharged into a grit chamber for sedimentation and purification. Flocculant is also discharged into the grit chamber through the inlet pipe to mix with the wastewater, further purifying the wastewater. The settled particles fall into the arc-shaped groove of the grit chamber. Then, the servo motor is activated, causing the annular plate to drive the U-shaped plate and grid plate to reverse. The U-shaped plate and grid plate reverse to scoop up the particles at the bottom of the sedimentation tank and separate them from the wastewater. The particles are then transported and collected by a conveyor, thus completing the wastewater purification without the need for manual removal of particles, thereby improving the wastewater purification efficiency.

[0017] 2. Under the action of the striking rod, whenever the annular plate drives the U-shaped plate and the grid plate to reverse, the rotation of the striking rod can strike and vibrate the annular plate, which in turn strikes and vibrates the U-shaped plate and the grid plate. The U-shaped plate and the grid plate vibrate the attached particles, which can prevent the particles from adhering to the grid plate and the U-shaped plate and making them difficult to collect, thus ensuring that all particles can be transported and collected.

[0018] 3. With the help of the observation window, whenever the U-shaped plate and grid plate dredge the particles, the operator can check the dredging situation through the observation window and take appropriate action in a timely manner based on the removal of the particles.

[0029] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0030] Example: A municipal wastewater purification device, please refer to [link / reference]. Figures 1-7As shown, the system includes a grit chamber 1 and a housing 2 installed in the middle of the grit chamber 1. The bottom rear side of the grit chamber 1 is inclined. An inlet pipe 3 is connected to the rear side of the left side of the grit chamber 1. An annular plate 4 is rotatably connected between the middle of the left and right sides inside the housing 2. The annular plate 4 has openings spaced apart to allow sewage to pass through. A gear ring I5 is fixedly connected circumferentially to the right side of the outer side of the annular plate 4. A servo motor 6 is installed on the upper right side of the housing 2. A spur gear 7 is fixedly connected to the end of the output shaft of the servo motor 6. The spur gear 7 meshes with the gear ring I5. The system also includes a U-shaped plate 8, a grid plate 9, an L-shaped rod 10, a guide ring 11, a trigger plate 12, a torsion spring 13, and a conveying assembly. The conveying assembly is installed on the housing 2. The U-shaped plates 8 are evenly spaced and fixed to the inner circumferential side of the annular plate 4. A grid plate 9 is rotatably connected to the U-shaped plate 8. The grid plate 9 and the U-shaped plate 8 form a frame. The rotation points of the grid plate 9 and the U-shaped plate 8 are separated by... Four torsion springs 13 are connected. An L-shaped rod 10 is fixedly fitted to the right end of the shaft of the grid plate 9. A guide ring 11 is fixedly connected to the right side of the inner side of the housing 2 along the circumference. The inner wall of the guide ring 11 contacts the end of the L-shaped rod 10. A trigger plate 12 is fixedly connected to the top of the guide ring 11. The trigger plate 12 consists of an arc-shaped segment and two straight segments. The two straight segments are respectively fixed to the end of the guide ring 11. The arc-shaped segment is connected to the two straight segments. The bottom of the sedimentation tank 1 is provided with an arc-shaped groove in the middle that contacts the grid plate 9 in reverse. This groove is used to collect the purified sedimented particles. Then, the annular plate 4 reverses and drives the U-shaped plate 8 to reverse. The U-shaped plate 8 reverses and drives the grid plate 9 to reverse. The U-shaped plate 8 and the grid plate 9 work together to lift the particles at the bottom of the sedimentation tank to the top for removal. The L-shaped rod 10 is controlled to swing by the trigger plate 12, so that the grid plate 9 swings and disengages from the particles. The particles fall onto the conveying assembly and are conveyed and collected.

[0031] Please see Figure 7 As shown, the conveying assembly includes a guide bucket 14, a mounting plate 141, a conveyor 142, and a drive motor 143. Two mounting plates 141 are fixedly connected to the upper right side of the housing 2, and the conveyor 142 is installed between the two mounting plates 141. The conveyor 142 consists of two conveying wheels and a conveyor belt. The conveying wheels are symmetrically rotated and connected between the two mounting plates 141, and the conveyor belt is wound between the two conveying wheels. When the conveyor 142 rotates forward, it can drive the particles to move to the right for conveying. The drive motor 143 is installed on the right side of the front side of the front mounting plate 141. The output shaft end of the drive motor 143 is fixedly connected to the front end of the conveying wheel on the right side of the conveyor 142. The guide bucket 14 is fixedly connected between the top left side of the front and rear mounting plates 141, and the guide bucket 14 can guide the particles.

[0032] First, wastewater is continuously discharged into the sedimentation tank from the rear. The wastewater passes through the opening of the annular plate 4, and flocculant is discharged into the sedimentation tank through the inlet pipe 3 to react with the wastewater. The wastewater undergoes sedimentation and purification in the sedimentation tank. Due to the inclined surface of the sedimentation tank, the settled particles are concentrated in the arc-shaped groove of the sedimentation tank. Then, the servo motor 6 is started to drive the spur gear 7 to rotate forward. The forward rotation of the spur gear 7 drives the gear ring I5 to rotate backward. The rotation of the gear ring I5 drives the annular plate 4 to rotate backward. The rotation of the annular plate 4 drives the U-shaped plate 8 to rotate backward. The rotation of the U-shaped plate 8 drives the grid plate 9 to rotate backward. When the grid plate 9 and the U-shaped plate 8 rotate backward and contact the arc-shaped groove of the sedimentation tank, the grid plate 9 and the U-shaped plate 8 cooperate to scoop up the particles at the bottom of the sedimentation tank, so that the particles rotate backward and are separated from the wastewater. At the same time, the rotation of the grid plate 9 drives the L-shaped rod 10 to rotate backward. The L-shaped rod 10 rotates and slides on the inner wall of the guide ring 11. When the L-shaped rod 10 reverses and contacts the trigger plate 12, the trigger plate 12 drives the L-shaped rod 10 to swing downwards. The L-shaped rod 10 drives the grid plate 9 to swing downwards, compressing the torsion spring 13. The grid plate 9 swings downwards and loses contact with the particles, which fall into the guide hopper 14. The particles in the guide hopper 14 fall onto the conveyor 142, which starts the drive motor 143 to rotate forward, driving the conveyor 142 to rotate forward. The conveyor 142 rotates forward, causing the particles to move to the right for collection. As the L-shaped rod 10 continues to reverse and lose contact with the trigger plate 12, the grid plate 9 swings upwards to reset due to the action of the torsion spring 13, driving the L-shaped rod 10 to swing upwards to reset. This process is repeated, continuously removing the particles from the bottom of the sedimentation tank 1, thus completing the wastewater purification without the need for manual removal of particles, thereby improving wastewater purification efficiency. After all the particles at the bottom of the sedimentation tank 1 are removed, the drive motor 143 is turned off, the conveyor 142 stops rotating forward, the servo motor 6 is turned off, the annular plate 4 stops driving the U-shaped plate 8 to rotate in reverse, and the U-shaped plate 8 stops driving the grid plate 9 to rotate in reverse.

[0033] Please see Figure 8As shown, it also includes a striking assembly installed between the housing 2 and the annular plate 4. The striking assembly includes a fixed plate 15, a rotating shaft 151, striking rods 152, and a transmission assembly. Fixed plates 15 are symmetrically fixed to the top of the housing 2. A rotating shaft 151 is rotatably connected between the lower parts of the fixed plates 15 on both sides. Four striking rods 152 are fixedly mounted on the rotating shaft 151. Adjacent striking rods 152 are staggered, and the ends of the striking rods 152 are made of rubber. When the striking rods 152 rotate and contact the annular plate 4, the striking rods 152 can achieve the striking action... The annular plate 4 is struck and vibrated to make the grid plate 9 vibrate. A transmission component is provided between the annular plate 4 and the rotating shaft 151. When the transmission component is in operation, it can drive the rotating shaft 151 to rotate. The transmission component includes a drive gear 153 and a gear ring II 154. The drive gear 153 is fixedly mounted on the left end of the rotating shaft 151. The gear ring II 154 is fixedly connected to the left side of the outer side of the annular plate 4 along the circumferential direction. The gear ring II 154 meshes with the drive gear 153. When the gear ring II 154 rotates, it can drive the drive gear 153 to rotate.

[0034] When the annular plate 4 reverses, it drives the gear ring II 154 to reverse as well. The reverse rotation of gear ring II 154 drives the drive gear 153 to rotate forward, which in turn drives the rotating shaft 151 to rotate forward. The rotating shaft 151 then drives the striking rod 152 to rotate forward. When the striking rod 152 contacts the annular plate 4, it vibrates and strikes the annular plate 4. Since the end of the striking rod 152 is made of rubber, it prevents damage to the annular plate 4. The vibration of the annular plate 4 vibrates the U-shaped plate 8 and the grid plate 9, thus dislodging and collecting the particles attached to them. When the annular plate 4 stops reversing, it stops driving gear ring II 154 to reverse, gear ring II 154 stops driving drive gear 153 to rotate forward, the rotating shaft 151 stops driving striking rod 152 to rotate forward, and the U-shaped plate 8 and grid plate 9 stop vibrating. This prevents particulate matter from adhering to the grid plate 9 and U-shaped plate 8, making it difficult to collect, thus ensuring that all particulate matter can be transported and collected.

[0035] Please see Figure 9 As shown, it also includes an observation window 16, which is symmetrically fixed and connected to the right side of the housing 2.

[0036] As particulate matter is being retrieved and removed, operators can observe the retrieval process through the observation window 16. This allows for timely adjustments based on the progress of particulate matter removal.
