Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to an integrated coagulation and sedimentation equipment for water conservancy projects. Background Technology

[0002] Coagulation and sedimentation is a commonly used water treatment method in hydraulic engineering, particularly suitable for treating high-turbidity raw water generated from river water intake, drainage during cofferdam construction, and reservoir operation. Its basic principle is to add a coagulant to the water, causing suspended sediment, colloids, and other tiny particles to coagulate into larger flocs, which are then separated by gravity settling, thus achieving water purification.

[0003] Existing integrated coagulation and sedimentation equipment used in water conservancy projects separates the control of sewage inflow and coagulant addition. Sewage enters the treatment tank through a water pump, while the coagulant is injected by an independent dosing device. This separate operation makes it difficult for the two to enter the treatment tank simultaneously, directly affecting floc formation and reducing treatment efficiency. Furthermore, the amount of coagulant added cannot be adjusted according to the sewage flow rate. When the flow rate fluctuates rapidly in water conservancy projects, the amount of coagulant added cannot keep up with the changes in water flow, which can easily lead to insufficient or excessive dosing, affecting the effluent quality and wasting chemicals. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated coagulation and sedimentation equipment for water conservancy projects, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an integrated coagulation and sedimentation equipment for water conservancy projects, comprising: a treatment tank, an inlet pipe fixed to the side wall of the treatment tank, a drain pipe fixed to the right side of the treatment tank, a reaction tank and a filter tank opened inside the treatment tank, a control panel fixed to the front of the treatment tank, a connecting pipe fixed to the bottom of the reaction tank, an electromagnetic valve provided on the outer wall of the connecting pipe, the electromagnetic valve being electrically connected to the control panel, and a filter frame fixed to the inner side of the filter tank; A stirring device is installed on the reaction tank.

The motor is fixed to the side wall of the treatment tank, the rotating shaft is fixed to the output end of the motor, and the stirring plate is fixed to the outer wall of the rotating shaft. A dosing tank is fixed to the top of the treatment tank. Coagulant is added to the dosing tank. The mixing of the chemical solution and the wastewater can be accelerated by setting the stirring plate. A dosing pipe runs through the treatment tank and is fixedly connected at the penetration point. The dosing pipe is connected to the dosing tank. A flip plate is hinged to the inside of the processing box, and an extrusion plate is fixed to the outer wall of the flip plate; A partition is fixed to the inside of the dosing tank, and the partition has through holes.

[0006] According to the above technical solution, a transmission rod passes through the bottom of the dosing tank and the top of the treatment tank, and the passage is slidably connected. A connecting plate is fixed to the top of the transmission rod, and a spring plate is fixed to the bottom of the connecting plate. The bottom of the spring plate is fixed to the inside of the dosing tank. By setting the spring plate, the connecting plate can be reset.

[0007] According to the above technical solution, a baffle is fixed at the end of the connecting plate, and the side wall of the baffle is in contact with the side wall of the partition. When the water inlet pipe discharges sewage into the reaction tank, the baffle can move upward to open the through hole, so that coagulant can be added at the same time.

[0008] According to the above technical solution, a diffusion device is provided above the treatment tank to improve the mixing efficiency of coagulant and sewage, and an anti-clogging device is provided on the dosing pipe to scrape off the crystals attached to the inner wall of the dosing pipe.

[0009] According to the above technical solution, the diffusion device includes: a fixing block, which is fixed to the inside of the reaction tank; A rotating rod is rotatably mounted on the inner side of a fixed block. The rotating rod passes through the side wall of the fixed block and is rotatably connected at the point of penetration. A diffusion plate is fixed to the outer wall of the rotating rod. The diffusion plate is used to diffuse the coagulant flowing into the reaction tank.

[0010] According to the above technical solution, a double-sided rack passes through the bottom of the fixed block and is slidably connected at the penetration point. A gear is fixed to the outer wall of the rotating rod. The double-sided rack meshes with the gear. An L-shaped block is fixed to the bottom of the double-sided rack. A protrusion is provided on the side of the L-shaped block away from the fixed block. An extrusion block is fixed to the outer wall of the transmission rod. An elastic sheet is fixed to the top of the L-shaped block. The top of the elastic sheet is fixed to the inner side of the reaction tank. The angle of the diffuser plate can be adjusted by the movement of the double-sided rack on the gear.

[0011] According to the above technical solution, the anti-clogging device includes: a long rod that passes through the top of the dosing tank and is slidably connected at the point of penetration; An L-shaped plate extends through the top of the dosing tank and is slidably connected at the point of penetration; the bottom of the L-shaped plate is fitted to the top of the baffle. A scraper ring is fixed to the outer wall of a long rod, and the outer wall of the scraper ring is in contact with the inner side of the dosing tube.

[0012] According to the above technical solution, a return spring is fixed to the bottom of the L-shaped plate, the bottom of the return spring is fixed to the top of the dosing tank, an L-shaped rod is fixed to the outer wall of the long rod, and a striking ball is fixed to the end of the L-shaped rod. The striking ball is used to strike the top of the dosing tube, which can treat the coagulant adhering inside the dosing tube.

[0013] This invention provides an integrated coagulation and sedimentation device for water conservancy projects. It has the following beneficial effects: 1. This invention achieves synchronous addition and adaptive adjustment of wastewater and coagulant by setting up components such as a flipping plate, a squeezing plate, a partition, a transmission rod, a connecting plate, a spring plate, a baffle, and a dosing pipe. Specifically, when wastewater enters the reaction tank through the inlet pipe, the water flow pushes the tilting plate to move, which in turn drives the baffle to move upward against the elastic force of the spring plates via the transmission rod and connecting plate. This gradually exposes the through holes on the baffle. At this time, the coagulant on the left side of the baffle flows smoothly into the right side through the through holes and finally enters the reaction tank through the dosing pipe. This achieves the simultaneous addition of coagulant and wastewater, solving the problem of low mixing efficiency caused by adding coagulant and wastewater separately. At the same time, the coagulant dosage can be automatically adjusted according to the wastewater flow rate. The larger the wastewater flow, the stronger the impact on the tilting plate, the greater the upward movement of the baffle, and the larger the opening of the through holes, allowing more coagulant to flow into the reaction tank. Conversely, when the flow rate decreases, the impact weakens, the baffle returns to its original position by the spring plates, the opening of the through holes decreases, and the dosage is reduced accordingly. This prevents waste caused by excessive coagulant addition and avoids problems such as insufficient coagulation and substandard treatment effect caused by insufficient addition.

[0014] 2. By setting up a fixed block, a rotating rod, and a diffuser plate, this invention enables some of the coagulant to remain on the diffuser plate when the dosing pipe adds coagulant to the reaction tank. The diffuser plate diffuses the coagulant entering the reaction tank, allowing the coagulant to come into contact with the wastewater over a wider range. This solves the problem that when coagulant is added to the reaction tank, it is discharged to only one place, resulting in the coagulant not being able to fully mix with the wastewater.

[0015] 3. By incorporating gears, double-sided racks, L-shaped blocks, elastic sheets, and extrusion blocks, this invention enables the diffuser plates to rotate downwards when the sewage flow rate entering the inlet pipe is too high. This reduces the angle between the two sets of diffuser plates, allowing the coagulant to flow quickly downwards into the reaction tank. This prevents the sewage flow rate entering the reaction tank from being too fast, which could prevent the coagulant from being discharged quickly from the diffuser plates and cause uneven mixing of sewage and coagulant.

[0016] 4. This invention, by setting up an L-shaped plate, a long rod, a return spring, and a scraper ring, can drive the scraper ring to move upward when the baffle moves upward to discharge coagulant into the dosing pipe. This allows the scraper ring to scrape off the crystals that grow inside the dosing pipe due to coagulant residue, thus avoiding the problem of long-term crystal growth in the dosing pipe, which can easily lead to blockage.

[0017] 5. By setting an L-shaped rod and a striking ball, the present invention can move the baffle downward. When no dosing operation is being performed, the striking ball can move downward to strike the top of the dosing pipe, thereby causing the dosing pipe to vibrate. The vibration can shake off a large amount of coagulant adhering to the inner wall of the dosing pipe, thus solving the problem that if a large amount of coagulant adheres to the dosing pipe, it will easily accelerate the crystallization of the coagulant.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-6 One embodiment of the present invention is: an integrated coagulation and sedimentation device for water conservancy projects, comprising: a treatment tank 1, an inlet pipe 2, a reaction tank 3, a filter tank 4, a drain pipe 5, a connecting pipe 6, a solenoid valve 7, a filter frame 8, a tilting plate 9, a stirring device 10, a dosing tank 11, a squeezing plate 12, a partition plate 13, a transmission rod 14, a connecting plate 15, a spring plate 16, and a baffle plate 17; the inlet pipe 2 is fixed to the side wall of the treatment tank 1, the drain pipe 5 is fixed to the right side of the treatment tank 1, and a reaction tank is opened inside the treatment tank 1. The reaction tank 1 consists of a tank 3 and a filter tank 4. A control panel is fixed to the front of the reaction tank 1. A connecting pipe 6 is fixed to the bottom of the reaction tank 3, and a solenoid valve 7 is installed on the outer wall of the connecting pipe 6. The solenoid valve 7 is electrically connected to the control panel. A filter frame 8 is fixed to the inner side of the filter tank 4. A stirring device 10 is installed on the reaction tank 3. The stirring device 10 includes a motor, a rotating shaft, and a stirring plate. The motor is fixed to the side wall of the reaction tank 1, the rotating shaft is fixed to the output end of the motor, and the stirring plate is fixed to the outer wall of the rotating shaft. A dosing device is fixed to the top of the reaction tank 1. The treatment tank 11 contains a dosing tank filled with coagulant. A stirring plate accelerates the mixing of the coagulant with the wastewater. A dosing pipe 18 passes through the treatment tank 1 and is fixedly connected at the penetration point. The dosing pipe 18 communicates with the inside of the dosing tank 11. A tilting plate 9 is hinged to the inside of the treatment tank 1, and a pressing plate 12 is fixed to the outer wall of the tilting plate 9. A partition plate 13 is fixed to the inside of the dosing tank 11 and has through holes. A transmission rod 14 passes through the bottom of the dosing tank 11 and the top of the treatment tank 1, and slides at the penetration point. The connection is as follows: a connecting plate 15 is fixed to the top of the transmission rod 14, and a spring plate 16 is fixed to the bottom of the connecting plate 15. The bottom of the spring plate 16 is fixed to the inside of the dosing tank 11. By setting the spring plate 16, the connecting plate 15 can be reset. A baffle 17 is fixed to the end of the connecting plate 15. The side wall of the baffle 17 is in contact with the side wall of the partition 13. When the water inlet pipe 2 discharges sewage into the reaction tank 3, the baffle 17 can move upward to open the through hole, so that coagulant can be added at the same time.

[0022] By setting up a flip plate 9, a squeezing plate 12, a partition plate 13, a transmission rod 14, a connecting plate 15, a spring plate 16, a baffle 17, and a dosing pipe 18, the wastewater can enter the reaction tank 3 through the inlet pipe 2, while the baffle 17 can move upward, exposing the through hole on the partition plate 13. This allows the coagulant on the left side of the partition plate 13 to flow through the through hole to the right side of the partition plate 13, and then the dosing pipe 18 can be added into the reaction tank 3. This achieves the effect of adding coagulant and wastewater simultaneously, solving the problem of poor mixing efficiency caused by adding coagulant and wastewater separately. Furthermore, by adjusting the sewage flow rate, the impact force on the tilting plate 9 can be changed, thereby allowing the baffle 17 to move up and down. This enables the dosage of the coagulant to be adjusted according to the sewage flow rate, preventing waste caused by excessive coagulant addition or insufficient coagulation and substandard treatment results due to insufficient coagulant addition.

[0023] In this embodiment, when wastewater for water flow engineering needs to be treated, the wastewater is added to the reaction tank 3 through the inlet pipe 2. When the inlet pipe 2 enters the reaction tank 3, the wastewater impacts the tilting plate 9, causing it to rotate upwards. This rotation drives the extrusion plate 12 to rotate upwards. As the extrusion plate 12 rotates upwards, it compresses the transmission rod 14, causing it to move into the dosing tank 11. This movement drives the connecting plate 15 upwards. As the connecting plate 15 moves upwards, the spring plate 16 is stretched and reduced in size. Simultaneously, the through hole on the baffle 17 opens, allowing the coagulant on the left side of the baffle 17 to flow through the through hole to the right side of the baffle 17. This allows the coagulant to enter the dosing pipe 18. Through the dosing pipe 18, the coagulant can... The coagulant is added to the reaction tank 3 simultaneously. When the flow rate of sewage into the reaction tank 3 is too large, the pressure on the tilting plate 9 is too large, which increases the upward tilting range of the pressure plate 12. This causes the transmission rod 14 to move the connecting plate 15 upward a greater distance, which reduces the obstruction of the through hole by the baffle 17 driven by the connecting plate 15. This increases the flow rate of coagulant added to the reaction tank 3 by the dosing pipe 18. When the inlet pipe 2 stops discharging sewage, the spring plate 16 is in a stretched state, which causes the spring plate 16 to move the connecting plate 15 downward. This causes the connecting plate 15 to move the transmission rod 14 downward, and the connecting plate 15 to move the baffle 17 downward, thus sealing the through hole and stopping the dosing operation of the dosing pipe 18. When the transmission rod 14 moves downward, it can squeeze the pressure plate 12 downward and rotate it back to its original position.

[0024] By starting the motor, the rotating shaft can be turned, which in turn drives the stirring plate to rotate, thus agitating the wastewater and coagulant. After the wastewater coagulation is completed, the solenoid valve 7 is activated through the control panel to open the connecting pipe 6. When the connecting pipe 6 is open, the coagulated wastewater can be added to the filter tank 4, allowing the wastewater to enter the filter frame 8 for filtration. Clean water is then discharged through the mesh of the filter frame 8 and discharged from the filter tank 4 through the drain pipe 5.

[0025] Please see Figures 1-6Based on the above embodiments, in another embodiment of the present invention, a diffusion device is provided above the treatment tank 1, which is used to improve the mixing efficiency of coagulant and sewage. The diffusion device includes: a fixed block 191, a rotating rod 192, a diffusion plate 193, a gear 194, a double-sided rack 195, an L-shaped block 196, an elastic sheet 197, and a pressing block 198. The fixed block 191 is fixed to the inner side of the reaction tank 3. The rotating rod 192 is rotatably mounted on the inner side of the fixed block 191. The rotating rod 192 passes through the side wall of the fixed block 191 and is rotatably connected at the penetration point. The outer wall of the rotating rod 192 is fixed with a diffusion plate 193, which is used to diffuse the coagulant flowing into the reaction tank 3. A double-sided rack passes through the bottom of the fixed block 191. 195, and sliding connection at the through point, gear 194 is fixed on the outer wall of rotating rod 192, double-sided rack 195 meshes with gear 194, L-shaped block 196 is fixed at the bottom of double-sided rack 195, protrusion is provided on the side of L-shaped block 196 away from fixed block 191, extrusion block 198 is fixed on the outer wall of transmission rod 14, elastic sheet 197 is fixed at the top of L-shaped block 196, the top of elastic sheet 197 is fixed on the inner side of reaction tank 3, and the angle of diffuser plate 193 can be adjusted by moving double-sided rack 195 on gear 194.

[0026] By setting up the fixed block 191, the rotating rod 192 and the diffuser plate 193, when the dosing pipe 18 adds coagulant to the reaction tank 3, some of the coagulant can remain on the diffuser plate 193. The diffuser plate 193 can diffuse the coagulant entering the reaction tank 3, so that the coagulant can come into contact with the sewage more widely. This solves the problem that when the coagulant is added to the reaction tank 3, it is discharged to one place, which results in the coagulant not being able to fully contact and mix with the sewage. By setting gear 194, double-sided rack 195, L-shaped block 196, elastic sheet 197 and extrusion block 198, when the sewage flow rate entering the inlet pipe 2 is too large, the diffuser plate 193 will rotate downward, thereby reducing the angle between the two sets of diffuser plates 193. This allows the coagulant to flow downward into the reaction tank 3 quickly, preventing the sewage flow rate entering the reaction tank 3 from being too fast, which would cause the coagulant to not be discharged quickly on the diffuser plate 193, resulting in uneven mixing of sewage and coagulant.

[0027] An anti-clogging device is installed on the dosing tube 18. This device scrapes away crystals adhering to the inner wall of the dosing tube 18. The anti-clogging device includes: an L-shaped plate 201, a long rod 202, a return spring 203, an L-shaped rod 204, a striking ball 205, and a scraping ring 206. The long rod 202 passes through the top of the dosing tank 11 and is slidably connected at the penetration point. The L-shaped plate 201 passes through the top of the dosing tank 11 and is slidably connected at the penetration point. The bottom of the L-shaped plate 201 is flush with the top of the baffle 17. Ring 206 is fixed to the outer wall of long rod 202. The outer wall of scraper ring 206 is in contact with the inner side of dosing tube 18. A return spring 203 is fixed to the bottom of L-shaped plate 201. The bottom of return spring 203 is fixed to the top of dosing tank 11. An L-shaped rod 204 is fixed to the outer wall of long rod 202. A striking ball 205 is fixed to the end of L-shaped rod 204. The striking ball 205 is used to strike the top of dosing tube 18, which can treat the coagulant adhering inside dosing tube 18.

[0028] By setting up an L-shaped plate 201, a long rod 202, a return spring 203, and a scraper ring 206, when the baffle 17 moves upward to discharge coagulant into the dosing pipe 18, it can drive the scraper ring 206 to move upward, so that the scraper ring 206 can scrape off the crystals that grow inside the dosing pipe 18 due to coagulant residue, thus avoiding the problem of long-term crystal growth in the dosing pipe 18, which can easily lead to blockage of the dosing pipe 18; By setting up the L-shaped rod 204 and the striking ball 205, the baffle 17 can be moved downwards. When no dosing operation is being performed, the striking ball 205 can be moved downwards to strike the top of the dosing pipe 18, thereby causing the dosing pipe 18 to vibrate. Through vibration, a large amount of coagulant adhering to the inner wall of the dosing pipe 18 can be shaken off, solving the problem that if a large amount of coagulant adheres to the inside of the dosing pipe 18, it will easily accelerate the crystallization of the coagulant.

[0029] In this embodiment, during operation: when the coagulant is discharged from the dosing pipe 18, a portion of the coagulant is discharged onto the diffuser plate 193, allowing it to be discharged into the reaction tank 3. This diffuses the coagulant, ensuring uniform contact between the coagulant and the wastewater. When the flow of wastewater into the reaction tank 3 is excessive, the extrusion plate 12 can press the transmission rod 14 upwards. When the transmission rod 14 moves upwards, the extrusion block 198 presses against the protrusion of the L-shaped block 196, causing the L-shaped block 196 to move upwards under pressure. This compresses and deforms the elastic sheet 197. When the L-shaped block 196... When the transmission rod 14 moves upward, it can drive the double-sided rack 195 to move upward, so that the double-sided rack 195 moves on the gear 194, causing the gear 194 to rotate. The gear 194 drives the rotating rod 192 to rotate, causing the two sets of diffuser plates 193 to rotate downward, thus reducing the angle between the two sets of diffuser plates 193. When the transmission rod 14 moves downward and does not press the protrusion of the L-shaped block 196, because the elastic sheet 197 is in a compressed state, the elastic sheet 197 can drive the L-shaped block 196 to move downward, causing the double-sided rack 195 to move downward on the gear 194, thus causing the diffuser plate 193 to flip and reset. When the baffle 17 moves upward, it can press the L-shaped plate 201 upward, which in turn causes the L-shaped plate 201 to move the long rod 202 upward. When the L-shaped plate 201 moves upward, it will stretch and deform the return spring 203. When the long rod 202 moves upward, it can move the scraper ring 206 upward, which can scrape the inner wall of the dosing tube 18 and remove the crystals inside the dosing tube 18. When the baffle 17 returns to its original position and does not press the L-shaped plate 201, the return spring 203 can move the long rod 202 downward, which in turn causes the L-shaped rod 204 and the striking ball 205 to move downward, allowing the striking ball 205 to strike the top of the dosing tube 18 and knock off the coagulant attached to the inside of the dosing tube 18.

[0030] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
