Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a highly efficient integrated chemical phosphorus removal control system for an EGA intelligent tank and its usage method. Background Technology

[0002] Wastewater treatment generally requires nitrogen and phosphorus removal, which can lead to eutrophication of water bodies after treatment. Currently, phosphorus removal from wastewater typically involves anaerobic-aerobic biological methods and chemical flocculation. Chemical flocculation removes phosphorus by adding inorganic metal salts (such as iron and aluminum salts) to the wastewater, which react with soluble phosphates to form insoluble phosphate precipitates. Simultaneously, these metal salts undergo hydrolysis and polymerization in the water, generating polynuclear hydroxy complexes with long linear structures. These complexes effectively reduce or eliminate the potential of colloids in the water. Through charge neutralization, adsorption bridging, and floc sweeping, the colloids coagulate into larger flocs. Finally, phosphorus-containing flocs are removed from the wastewater through solid-liquid separation.

[0003] A search revealed that the invention with publication number CN117699977B discloses a BGA intelligent tank and method for wastewater treatment based on aerobic MBBR tanks. However, this method has the following drawbacks when switching to chemical flocculation:

[0004] In the process of treating wastewater by chemical flocculation, an appropriate amount of chemicals need to be added. Different types of chemicals are available in solid and liquid forms. During the addition process, granular chemicals may clump together, making the addition process difficult.

[0005] Furthermore, the amount of chemicals added during wastewater treatment needs to be adjusted according to the pH value of the water. Manual dosing is not precise enough and can easily lead to waste. Summary of the Invention

[0006] The purpose of this invention is to solve the shortcomings of existing technologies, such as the clumping of granular agents during the feeding process, which makes the feeding process difficult, and the imprecise manual feeding, which easily leads to waste.

[0017] In one possible design, a first sliding rod is slidably sleeved on the outer wall of the rotating tube, and a plurality of fixed shafts corresponding to the stirring spoon are fixedly provided on the outer wall of the rotating tube. The stirring spoon is rotatably sleeved on the corresponding fixed shaft. A rectangular opening corresponding to the plurality of fixed shafts is opened on the outer wall of the first sliding rod.

An electric push rod is fixedly provided on the bottom wall of the first sliding rod, and the output end of the electric push rod is fixedly connected to the bottom of the rotating tube.

[0018] In one possible design, a fixing ring is fixedly fitted on the outer wall of the rotating tube, and multiple support bars are fixedly fitted on the outer wall of the fixing ring. A slider is slidably mounted inside the support bars, and a positioning ball is embedded on the outer side of the slider. A groove for cooperating with the positioning ball is opened on the inner wall of the exhaust pipe. A sliding ring is slidably fitted on the outer wall of the rotating tube, and a connecting rod is rotatably mounted between the sliding ring and the multiple sliders. Multiple connecting rods are slidably mounted through the top of the fixing ring, and the two ends of the connecting rods are fixedly connected to the sliding ring and the adjacent side of the first sliding rod, respectively, to limit the position of the rotating tube during the opening of the stirring spoon.

[0019] In one possible design, an air chamber is formed between the two rotating plates, a piston block is slidably disposed within the stop block, an air inlet is provided at one end of the second sliding rod and the air inlet is located between the stop block and the piston block, a connecting pipe is fixedly provided at one end of the second sliding rod and the outer wall of the first material cylinder, the connecting pipe on the first material cylinder extends into the air chamber, a micro air pump is provided at the top of the support frame, the other end of the connecting pipe is connected to the micro air pump for inflating the air chamber and the space between the stop block and the piston block, and a three-way solenoid valve for venting is provided on the connecting pipe to adjust the feeding amount.

[0020] A method for using a high-efficiency integrated chemical phosphorus removal control system in an EGA smart tank includes the following steps:

[0021] S1. First, install the mounting plate on the EGA smart tank and insert the stirring spoon into the EGA smart tank. Then, start the electric push rod to move the first sliding rod downward, which can open the stirring spoon and move the positioning ball to the groove in the exhaust pipe to fix the rotating tube.

[0022] S2. Then, according to the state of the agent, put it into the first and second material cylinders respectively, and start the external water pump to pump sewage into the EGA smart tank. During the flow of sewage, the rubber sleeve will be aligned with the through hole. At this time, the liquid agent in the first material cylinder will flow into the EGA smart tank through the liquid inlet pipe for dosing.

[0023] S3. Simultaneously start the motor to drive the stirring spoon to rotate and stir, so that the agent and sewage are mixed and reacted.

[0024] S4. During the motor start-up process, it can drive the baffle and block to move back and forth in the discharge pipe, so that the granular medicine in the second material cylinder can be put into the rotating pipe and discharged through the discharge hole to mix and react with water.

[0025] S5. When it is necessary to adjust the amount of material fed, start the micro air pump to inflate the air chamber and the baffle, change the size of the rubber sleeve and the position of the baffle reset, and the amount of medicine can be increased or decreased.

[0026] In this application, the mounting plate is first installed on the EGA smart tank, and multiple stirring spoons are inserted into the EGA smart tank through the exhaust pipe. Then, the electric push rod is activated to drive the first sliding rod to move downward. The downward movement of the first sliding rod can drive the connecting column to move downward. During the downward movement of the connecting column, it can move in the waist-shaped hole, thereby driving the stirring spoon to open. The downward movement of the first sliding rod can drive the sliding ring to move downward through the connecting rod. The downward movement of the sliding ring can drive the slider to move in the support bar through the connecting rod, which can drive the positioning ball to move into the groove in the exhaust pipe to limit the rotation tube.

[0027] Then, depending on the state of the agent, it is put into the first and second material cylinders respectively, and the external water pump is started to pump sewage into the EGA smart tank. During the flow of sewage, the rotating shaft is driven to rotate through the blades. The rotation of the rotating shaft can drive the two rotating plates to rotate. When the rubber sleeve corresponds to the through hole, the liquid agent in the first material cylinder will flow into the EGA smart tank through the liquid inlet pipe for dosing.

[0028] Simultaneously, the motor is started to drive the rotating tube to rotate. The rotation of the rotating tube can drive the first sliding rod to rotate through the fixed shaft. The rotation of the first sliding rod can drive the stirring spoon to rotate to stir, so that the reagent and sewage are mixed and reacted.

[0029] During the rotation of the rotating tube, the cam can be driven to rotate. When the cam's convex part contacts the sliding frame, it can drive the sliding frame to move and compress the spring. When the sliding frame moves, it can drive the second sliding rod to move in the discharge pipe and stretch the tension spring. The movement of the second sliding rod can drive the baffle and the stop block to move, so that the stop block moves to one side of the discharge port and to one side of the extension pipe. At this time, the particles in the second material cylinder will fall into the discharge pipe. When the sliding frame moves, it can also drive the rack to move. The movement of the rack can drive the gear to rotate. The rotation of the gear can drive the stirring shaft to rotate. The rotation of the stirring shaft can stir the agent in the second material cylinder and accelerate the discharge speed. When the cam's convex part moves away from the sliding frame, the sliding frame can be reset and moved under the action of the spring. The second sliding rod can be reset and moved under the action of the tension spring, driving the baffle and the stop block to be reset and moved. When the baffle moves to the other side of the discharge port, the stop block moves to the bottom of the extension pipe to block the extension pipe. At this time, the agent in the discharge pipe will be discharged into the rotating tube through the discharge port and discharged through the discharge hole to mix with the sewage.

[0030] When the amount of material to be fed needs to be adjusted, the micro air pump is started to inflate the air chamber and the baffle. When the gas enters the air chamber through the connecting pipe, it can squeeze the rubber sleeve, causing the rubber sleeve to deform and reducing the size of the feeding port. When the gas enters the second sliding rod through the connecting pipe, it can be discharged between the baffle and the piston block through the air inlet, which can drive the piston block to move within the baffle, change the reset position, and slow down the feeding. However, the moving speed of the baffle and the piston block remains unchanged, which can change the feeding amount. When the adjustment is too large, the three-way solenoid valve can be opened to discharge the gas, which can realize the increase or decrease of the dosage of the agent. Beneficial effects

[0031] In this invention, the highly efficient integrated chemical dephosphorization control system in the EGA intelligent tank, through the cooperation of structures such as the first sliding rod, fixed shaft, connecting column, and waist-shaped hole, allows the stirring spoon to be flexibly unfolded and retracted while maintaining a stable stirring effect. The drive of the electric push rod makes the unfolding and retraction process of the stirring spoon more stable and reliable, improving the overall stability and service life of the system. During the unfolding process of the stirring spoon, the position limit of the rotating tube is achieved through the cooperation of structures such as the fixed ring, support bar, slider, positioning ball, sliding ring, connecting rod, and connecting rod. This limiting mechanism not only ensures the stability of the stirring spoon during the unfolding process, but also avoids damage or failure of the rotating tube due to excessive movement, thus improving the safety and reliability of the system.

[0032] In this invention, the highly efficient integrated chemical phosphorus removal control system in the EGA intelligent tank uses a first and a second feed cylinder to respectively handle the dispensing of different agents. Through the coordinated operation of the discharge mechanism and the rotating tube, the two agents can be dispensed alternately or simultaneously, thus meeting the diverse needs of complex water quality treatment.

[0033] In this invention, the highly efficient integrated chemical phosphorus removal control system in the EGA intelligent tank can flexibly control the amount of chemical agent to be added by adjusting the size of the rubber sleeve and the position of the piston block in the baffle, so as to adapt to different water qualities and treatment needs. At the same time, the use of a three-way solenoid valve further refines the adjustment range of the amount of chemical agent, ensuring the optimization of the phosphorus removal effect.

[0034] In this invention, by making the stirring spoon retractable and positioning the mounting plate and exhaust pipe together, it can be easily installed on the EGA smart tank later, which can improve its applicability. Moreover, it can automatically limit the position after installation, making installation and use convenient. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0047] Example 1

[0048] Reference Figures 1-10 A highly efficient integrated chemical phosphorus removal control system for an EGA smart tank, which is used in the field of wastewater treatment, includes: an EGA smart tank 1, which is the same as the one used in patent document CN117699977B, with an inlet pipe 2 and a drain pipe 3 respectively installed on both sides of the EGA smart tank 1 to ensure that water can flow smoothly in and out.

[0049] At least two exhaust pipes 4 are fixedly installed through the top of the EGA intelligent tank 1 to discharge the gas generated during the treatment process. Then, a mounting plate 5 is fitted on the top of the two exhaust pipes 4 to fix the subsequent reagent dosing and stirring device.

[0050] A first material cylinder 6 is installed through the top of the mounting plate 5 to store liquid chemical dephosphorization agent. The bottom of the first material cylinder 6 is connected to the EGA intelligent tank 1 through the liquid inlet pipe 19 to ensure that the agent can be smoothly added into the tank.

[0051] A fixing plate 20 is fixedly installed inside the first material cylinder 6, and two mounting grooves 22 are opened on the inner wall of the first material cylinder 6. A rotating plate 23 is rotatably installed in the mounting grooves 22 to ensure that the rotating plate 23 can rotate freely. Through holes 21 are opened on the top of both the rotating plate 23 and the fixing plate 20, and the same rubber sleeve 25 is fixedly installed in the through holes 21 of the two rotating plates 23 to control the amount of agent to be dispensed. The size of the rubber sleeve 25 can be adjusted to change the amount of agent to be dispensed.

[0052] A connecting cylinder 12 is fixedly installed on the water inlet pipe 2, and the connecting cylinder 12 and the water inlet pipe 2 are eccentrically positioned. A rotating shaft 17 is rotatably installed through the top of the connecting cylinder 12, and multiple blades 18 are fixedly installed on the outer wall of the rotating shaft 17. The top of the rotating shaft 17 passes through the first feed cylinder 6 and the fixing plate 20, and is fixedly connected to two rotating plates 23. When water flows through the water inlet pipe 2, it will drive the blades 18 to rotate, thereby driving the rotating plates 23 and the rubber sleeve 25 to rotate. When the rubber sleeve 25 corresponds to the through hole 21, the automatic dispensing of the agent is realized.

[0053] A support frame 7 is set on the top of the mounting plate 5, and one end is fixedly connected to the first material cylinder 6. A rotating tube 14 is rotatably installed through the top of the support frame 7, and multiple retractable stirring spoons 16 are set on the rotating tube 14 to avoid interference with the exhaust pipe 4 during installation.

[0054] A motor 15 is installed at the bottom of the support frame 7, and the output end of the motor 15 is connected to the rotating tube 14 to provide rotational power to the rotating tube 14, thereby driving the stirring spoon 16 to rotate and realize the stirring of the liquid in the tank.

[0055] A second material cylinder 8 is fixedly installed on the top of the support frame 7 for storing granular chemical dephosphorization agent. An extension pipe 40 is provided at the bottom of the second material cylinder 8, and a discharge pipe 41 is obliquely installed through the bottom end of the extension pipe 40. A second sliding rod 43 is slidably installed through one side of the discharge pipe 41, and a baffle 44 and a stop block 45 are fixedly sleeved on the outer wall of the second sliding rod 43 to form a receiving cavity. A discharge port 42 is opened at the bottom of the discharge pipe 41 and corresponds to the hopper 13 at the top of the rotating pipe 14. When the stop block 45 moves to the bottom of the extension pipe 40 to seal the extension pipe 40, the baffle 44 moves to the side of the discharge port 42, and the agent in the receiving cavity is discharged.

[0056] A cam 51 is fixedly sleeved on the outer wall of the rotating tube 14, and a sliding seat 53 is fixedly installed on the top of the support frame 7. A sliding frame 48 that works with the cam 51 is slidably installed through one side of the sliding seat 53, and one end of the second sliding rod 43 is slidably sleeved on the sliding frame 48.

A tension spring 49 is sleeved on the outer wall of the second sliding rod 43, with both ends fixedly connected to the discharge pipe 41 and the second sliding rod 43 respectively, to provide reset power for the second sliding rod 43.

[0057] Meanwhile, a stirring shaft 50 is rotatably mounted through the top of the second material cylinder 8, and a gear 54 is fixedly mounted on the outer wall of the stirring shaft 50. A rack 55 that meshes with the gear 54 is fixedly mounted on one side of the sliding frame 48, which is used to stir the medicine in the second material cylinder 8, prevent clumping, and enable the movement of the lumpy medicine.

[0058] Example 2

[0059] refer to Figures 1-10 Improvements based on Example 1: To adjust the dosage, an air chamber 24 is formed between the two rotating plates 23. A piston block 47 is slidably disposed within the stop block 45. An air inlet 46 is provided at one end of the second sliding rod 43, located between the stop block 45 and the piston block 47. A connecting pipe 10 is fixedly provided at one end of the second sliding rod 43 and on the outer wall of the first material cylinder 6. The connecting pipe 10 on the first material cylinder 6 extends into the air chamber 24. A micro air pump 9 is provided at the top of the support frame 7. The other end of the connecting pipe 10 is connected to the micro air pump 9. The micro air pump 9 is the same as that used in patent document CN221414143U, used to inflate the air chamber 24 and the space between the stop block 45 and the piston block 47. The device is equipped with a three-way solenoid valve 11 for venting. The three-way solenoid valve 11 adopts the three-way solenoid valve in patent document CN106594318B. It adjusts the feeding amount. When the gas enters the gas chamber 24 through the connecting pipe 10, it can squeeze the rubber sleeve 25, causing the rubber sleeve 25 to deform and making the feeding port smaller. The rotation speed of the rotating plate 23 remains unchanged, and the feeding port is reduced, thereby changing the feeding amount. When the gas enters the second sliding rod 43 through the connecting pipe 10, it can be discharged between the baffle 45 and the piston block 47 through the air inlet 46. It can drive the piston block 47 to move within the baffle 45, change the reset position, and slow down the feeding. The moving speed of the baffle 45 and the piston block 47 remains unchanged, thereby changing the feeding amount.

[0060] A first sliding rod 26 is slidably sleeved on the outer wall of the rotating tube 14, and a rectangular opening 27 corresponding to multiple fixed shafts 28 is opened on it. The stirring spoon 16 is rotatably sleeved on the fixed shaft 28, and the connecting post 38 on the first sliding rod 26 cooperates with the waist-shaped hole 37 on one side of the stirring spoon 16 to realize the storage and unfolding of the stirring spoon 16. An electric push rod 39 is installed on the bottom wall of the first sliding rod 26, and its output end is fixedly connected to the bottom of the rotating tube 14. The unfolding and storage of the stirring spoon 16 is controlled by the extension and retraction of the electric push rod.

[0061] A fixing ring 31 is fixedly sleeved on the outer wall of the rotating tube 14, and multiple support bars 29 are installed on it. A slider 32 is slidably arranged inside the support bar 29, and a positioning ball 35 is embedded on the outside of the slider 32, which cooperates with the groove on the inner wall of the exhaust pipe 4 to achieve the initial positioning of the rotating tube 14 in the vertical direction.

[0062] A sliding ring 30 is slidably sleeved on the outer wall of the rotating tube 14 and connected to multiple sliders 32 via a connecting rod 33. At the same time, the sliding ring 30 is connected to the first sliding rod 26 via a connecting rod 34. In this way, when the electric push rod 39 pushes the first sliding rod 26, it can drive the sliding ring 30 and the connecting rod 33 to move, thereby adjusting the position of the sliders 32 and the positioning ball 35, and realizing the position limit of the rotating tube 14 during the opening of the stirring spoon 16.

[0063] A method for using a high-efficiency integrated chemical phosphorus removal control system in an EGA smart tank, characterized by comprising the following steps:

[0064] S1. First, install the mounting plate 5 on the EGA smart tank 1 and insert the stirring spoon 16 into the EGA smart tank 1. Then, start the electric push rod 39 to drive the first sliding rod 26 to move downward, which can drive the stirring spoon 16 to open and drive the positioning ball 35 to move into the groove in the exhaust pipe 4 to fix the rotating tube 14.

[0065] S2. Then, according to the state of the agent, it is put into the first material cylinder 6 and the second material cylinder 8 respectively, and the external water pump is started to pump sewage into the EGA smart tank 1. During the flow of sewage, the rubber sleeve 25 will be aligned with the through hole 21. At this time, the liquid agent in the first material cylinder 6 will flow into the EGA smart tank 1 through the liquid inlet pipe 19 for dosing.

[0066] S3. Simultaneously start motor 15 to drive stirring spoon 16 to rotate and stir, so that the agent and sewage are mixed and reacted.

[0067] S4. During the start-up process of motor 15, it can drive baffle 44 and block 45 to move back and forth in discharge pipe 41, so that the granular medicine in second material cylinder 8 can be put into rotating pipe 14 and discharged through discharge hole 36 to mix and react with water.

[0068] S5. When it is necessary to adjust the amount of material to be dispensed, start the micro air pump 9 to inflate the air chamber 24 and the stop block 45, change the size of the rubber sleeve 25 and the reset position of the stop block 45, so as to increase or decrease the amount of medicine dispensed.

[0069] However, as is well known to those skilled in the art, the working principles and wiring methods of the EGA intelligent slot 1, micro air pump 9, three-way solenoid valve 11, motor 15 and electric push rod 39 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0070] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
