Description

[0001] The invention relates to the technical field of sewage treatment, in particular to a polyferric sulfate processing and delivery device and method for sewage treatment. Background Art

[0002] During the sewage treatment process, the water contains a large amount of suspended solids, organic matter, heavy metals, and nutrients such as phosphorus. If these pollutants are discharged directly without effective treatment, they will cause serious pollution to the water environment and trigger a series of ecological problems, such as eutrophication of water bodies and death of aquatic organisms. Polyferric sulfate processing and delivery devices are now often used to pre-treat sewage.

[0003] There are many existing technologies for delivery devices, such as:

[0004] Chinese patent publication number CN117164091B discloses a catalytic agent delivery device and delivery method for sewage treatment. The catalytic agent delivery device includes: a treatment tank, a dosing component, a moving component and a control component; the moving component is arranged above the treatment tank, the dosing component includes a stirring mechanism and a dosing mechanism driven by pressure, the dosing component is connected to the moving component, and the catalytic agent is delivered to different areas of the treatment tank by movement; the control component is signal-connected to the moving component and the dosing component, and is used to control the movement of the moving component and the delivery of the catalytic agent in the dosing component. The dosing component and the moving component of the invention cooperate with each other, so that the catalytic agent can be evenly delivered into the sewage, the delivery efficiency of the agent can be improved, and the degree of degradation of the sewage can be increased.

[0005] The existing dosing device inputs the polyferric sulfate agent into the sewage tank through the infusion end during the dosing process. Since the polyferric sulfate agent diffuses slowly, the reaction process between the agent and the impurities in the sewage is relatively slow, which affects the sewage treatment efficiency. At the same time, after the agent is added, it is usually necessary for operators to stir it, which increases the labor intensity of the operators.

[0010] As a further improvement of the technical solution, a return spring is provided between the slide rod and the inner wall of the column, and when the pressure on the pressure head stops, the slide rod is reset by the force of the return spring.

[0016] The second object of the present invention is to provide a method for processing and placing polyferric sulfate for sewage treatment, comprising any one of the above-mentioned polyferric sulfate processing and placing devices for sewage treatment, comprising the following steps:

[0017] S1. The output end of the rotating motor drives the screw to rotate, so that the moving seat moves horizontally on the surface of the screw. When the moving seat moves, the moving seat drives the solution tank to move horizontally above the sewage tank, and discharges the polyferric sulfate agent to the sewage in the sewage tank through the infusion tube at the output end of the metering pump, so that the polyferric sulfate agent is evenly sprinkled on the sewage in the sewage tank;

[0018] S2.

At the same time, when the moving seat moves, it drives the cleaning component to move horizontally to brush the surface of the mixing component, thereby removing the sediment attached to the surface of the mixing component;

[0019] S3. After the polyferric sulfate agent is added, the shaking wastewater in the sewage tank is quickly blocked and leveled through the leveling component, so that the suspended particles in the sewage settle to the bottom of the water.

While the water is being ejected, it impacts the nearby water. When the injection disk impacts the sewage inside the sewage tank in turn, there is a large impact force between the wastewaters, so that the sewages are mixed, thereby improving the mixing efficiency of the sewage and the polyferric sulfate agent.

[0022] 2. In the polyferric sulfate processing and delivery device for sewage treatment, the moving seat drives the supporting block to move in the horizontal direction. At this time, the moving roller is attached to the bottom of the sewage tank and is caught inside the supporting block by friction. When the moving roller rotates, it drives the cleaning brush to rotate. Since the bristles on the surface of the cleaning brush are arc-shaped and fit with the top of the spray disc, the cleaning brush brushes the surface of the spray disc when it rotates, thereby avoiding the spray port on the surface of the spray disc from being blocked and ensuring the spray effect of the spray disc.

[0023] 3. In the polyferric sulfate processing and delivery device for sewage treatment, the piston rod at the end of the control cylinder drives the second rack to move horizontally, and the second rack drives the fixed gear to rotate during the movement, so that the baffle rotates on the surface of the fixed block. When the baffle rotates to be vertical to the sewage, it stops rotating. The baffle blocks the sewage ripples in the impact and stirring, so that the sewage can be quickly calmed without external force, which makes it easier for suspended particles in the sewage to settle to the bottom of the water, thereby accelerating the treatment efficiency of sediment in the sewage.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] One of the purposes of the present invention is to provide a polyferric sulfate processing and delivery device for sewage treatment, referring to Figure 1-Figure 7As shown, it includes a sewage tank 100, a rotating motor 101 is provided at the end of the sewage tank 100, a screw rod 102 is provided at the output end of the rotating motor 101, a moving seat 103 is provided on the surface of the screw rod 102, pressing rods 104 are provided on both sides of the moving seat 103, and the ends of the pressing rods 104 extend to the outer wall of the sewage tank 100, and a mixing component 300 is provided below the pressing rod 104. When the pressing rod 104 moves horizontally, it squeezes the mixing component 300, and the mixing component 300 impacts the sewage inside the sewage tank 100, so that the sewage is in a mixed state. When the moving seat 103 moves, it drives the pressing rod 104 to move horizontally. A support frame 200 is provided on the top of the moving seat 103, and the support frame 200 00 is provided with a solution tank 201 on the surface, and polyferric sulfate is contained in the solution tank 201. A metering pump 202 is provided at the bottom of the solution tank 201. An infusion tube 203 is provided at the end of the metering pump 202. The free end of the infusion tube 203 extends to the inside of the sewage tank 100. A cleaning component 400 is provided at the bottom of the movable seat 103. When the movable seat 103 moves, the water outlet on the surface of the mixing component 300 is cleaned. Leveling components 500 are provided on both sides of the inner wall of the sewage tank 100. After the polyferric sulfate is added to the inside of the sewage tank 100, the sewage in the mixed state in the sewage tank 100 is stopped by the leveling component 500, so that the impurities in the sewage react with the polyferric sulfate and precipitate.

[0039] When treating sewage by injecting polyferric sulfate agent into the sewage, since the diffusion velocity of polyferric sulfate in the sewage in the sewage tank 100 is slow, it takes a long time to mix, and the sewage and the polyferric sulfate agent are not mixed evenly during the mixing process, resulting in low sewage treatment efficiency. Therefore, the mixing component 300 includes a column 301 arranged on the outer wall of the sewage tank 100, a sliding rod 302 is slidably provided on the inner wall of the column 301, a pressure head 303 is provided on the top of the sliding rod 302, a curved tube 305 is provided at the end of the column 301, and a jet disk 306 is provided at the end of the curved tube 305, and the jet disk 306 is fixed at the bottom of the sewage tank 100. Pressing the pressure head 303 drives the sliding rod 302 to move downward in the vertical direction, and the sliding rod 302 squeezes the sewage inside the column 301, so that the sewage is ejected from the top of the jet disk 306 under pressure, and at the same time, the sewage near the jet disk 306 is impacted and stirred. During the treatment, the output end of the rotating motor 101 drives the screw rod 102 to rotate, so that the movable seat 103 drives the solution tank 201 to move horizontally above the sewage tank 100, and the polyferric sulfate agent is discharged to the sewage in the sewage tank 100 through the infusion tube 203 at the output end of the metering pump 202, so that the polyferric sulfate agent is evenly sprinkled on the sewage in the sewage tank 100. At the same time, when the movable seat 103 moves, it drives the pressing rod 104 to press the top of the pressure head 303, and the pressure head 303 pushes the sliding rod 302 to slide on the inner wall of the column 301 and squeezes the water inside the column 301, so that the water is ejected through the top of the injection disc 306, and the nearby water body is impacted while the water body is ejected. When the injection disc 306 impacts the sewage inside the sewage tank 100 in turn, there is an increased impact force between the wastewaters, so that the sewage is mixed, thereby improving the mixing efficiency of the sewage and the polyferric sulfate agent.

[0040] When the polyferric sulfate agent is injected into the sewage, in order to make the injection disc 306 perform multiple periodic injections into the sewage and accelerate the mixing efficiency of the polyferric sulfate agent and the sewage, a return spring 304 is provided between the slide bar 302 and the inner wall of the column 301. When the pressure on the pressure head 303 stops, the slide bar 302 is reset by the force of the return spring 304. When the pressing rod 104 moves to the end of the pressure head 303 to press it, the pressure head 303 squeezes the slide bar 302 to slide on the inner wall of the column 301. When the moving seat 103 drives the pressing rod 104 to continue moving, the pressure on the pressure head 303 disappears. At this time, the slide bar 302 is pulled by the restoring force of the return spring 304 to reset the return spring 304, so that the pressing rod 104 repeatedly presses the pressure head 303 when it moves, so that the water injected by the injection disc 306 impacts the sewage, thereby improving the sewage treatment efficiency.

[0041] In the process of sewage treatment, in order to prevent the metal precipitation generated in the process of decontamination from clogging the injection port on the top of the injection disk 306, resulting in reduced mixing efficiency, the cleaning component 400 includes a support block 401 fixed to the bottom of the movable seat 103, and a moving roller 402 is provided inside the support block 401 for rotation. The moving roller 402 is attached to the bottom of the sewage tank 100. When the movable seat 103 drives the support block 401 to move, the moving roller 402 is rotated inside the support block 401 by friction. Cleaning brushes 403 are connected to both sides of the moving roller 402, and the bristles on the surface of the cleaning brush 403 are The movable seat 103 is arc-shaped and fits with the top of the injection disc 306. When the movable seat 103 moves, it drives the support block 401 to move horizontally. At this time, the movable roller 402 is attached to the bottom of the sewage tank 100 and is caught by the friction force inside the support block 401. When the movable roller 402 rotates, it drives the cleaning brush 403 to rotate. Since the bristles on the surface of the cleaning brush 403 are arc-shaped and fit with the top of the injection disc 306, the cleaning brush 403 brushes the surface of the injection disc 306 when it rotates, thereby avoiding the injection port on the surface of the injection disc 306 from being blocked, thereby ensuring the injection effect of the injection disc 306.

[0042] Considering that the effective ingredients of the polyferric sulfate agent in the solution tank 201 are easily precipitated during the static process, resulting in uneven concentration of polyferric sulfate, it is easy to cause uneven distribution of the agent amount during the sewage treatment process. After the effective ingredients are precipitated, the concentration of the polyferric sulfate agent in the upper layer of the solution tank 201 is lower than the set standard, resulting in failure to achieve the expected treatment effect and increased treatment costs. Therefore, a gear rod 404 is rotatably provided at the top of the support block 401, and a connecting shaft sleeve 405 is provided at the end of the gear rod 404. A stirring blade 406 is provided at the top of the connecting shaft sleeve 405. The stirring blade 406 penetrates into the solution tank 201, and the support block When 401 moves, the gear rod 404 meshes and rotates with the first rack 105, and the gear rod 404 drives the stirring blade 406 at the end of the connecting sleeve 405 to stir the solution inside the solution tank 201. When the moving roller 402 moves, the gear rod 404 meshes and rotates at the end of the first rack 105, and the gear rod 404 drives the stirring blade 406 at the end of the connecting sleeve 405 to rotate, so that the polyferric sulfate agent inside the solution tank 201 is always in a stirred and mixed state, so that when performing sewage treatment operations, it is possible to avoid different concentrations of polyferric sulfate agents to treat sewage, and avoid cost waste caused by excessive concentration due to polyferric sulfate deposition.

[0043] Considering that the polyferric sulfate agent inside the solution tank 201 is easily deposited on the inner wall of the solution tank 201, in order to ensure the metering concentration of the agent, an extension arm 407 is provided on one side of the stirring blade 406, and a slide groove is provided at the end of the extension arm 407. A scraper 408 is slidably provided in the slide groove. An elastic member 409 is provided between the slide groove and the scraper 408, and the scraper 408 is in contact with the inner wall of the solution tank 201. When the stirring blade 406 stirs the agent solution inside the sewage tank 100, the extension arm 407 rotates coaxially with the stirring blade 406, and the scraper 408 provided at the end of the extension arm 407 is pressed against the inner wall of the solution tank 201 by the force of the elastic member 409, so that the scraper 408 scrapes the inner wall of the solution tank 201, so that the deposited adhering to the inner wall of the solution tank 201 is dissolved again, thereby ensuring the metering concentration of the agent, maintaining an ideal dosage during the decontamination process, and improving the use efficiency of the agent.

[0044] When the polyferric sulfate agent is mixed with the sewage, the liquid sprayed by the injection disk 306 impacts and stirs the sewage. When the injection of the polyferric sulfate agent into the sewage is stopped, the sewage needs to be calmed so that the floating objects in the water can be settled. In order to quickly calm the sewage in the sewage tank 100, the calming component 500 includes a fixed block 501 arranged on the inner wall of the sewage tank 100, and a baffle 502 is rotatably arranged on the inner wall of the fixed block 501. A torsion spring 503 is arranged between the fixed block 501 and the baffle 502. The baffle 502 is flush with the inside of the sewage tank 100 due to the force of the torsion spring 503. A groove is opened at the center of the baffle 502, and a fixed gear 504 is arranged in the groove. The sewage tank 100 is twice A cylinder 505 is provided, and a second rack 506 is provided at the end of the cylinder 505. The second rack 506 slides on the inner wall of the sewage tank 100. When the second rack 506 moves, it drives the fixed gear 504 to rotate. The second rack 506 is driven to move horizontally by controlling the piston rod at the end of the cylinder 505. The second rack 506 drives the fixed gear 504 to rotate during the movement, so that the baffle 502 rotates on the surface of the fixed block 501. When the baffle 502 rotates to be vertical to the sewage, it stops rotating. The baffle 502 blocks the sewage ripples in the impact stirring, so that the sewage can be quickly calmed without external force, which is convenient for the suspended particles in the sewage to settle to the bottom of the water, thereby increasing the sewage treatment efficiency.

[0045] When in use, the output end of the rotating motor 101 drives the screw rod 102 to rotate, so that the movable seat 103 moves horizontally. When the movable seat 103 moves on the surface of the screw rod 102, the movable seat 103 drives the solution tank 201 to move horizontally above the sewage tank 100, and the polyferric sulfate agent is discharged to the sewage in the sewage tank 100 through the infusion tube 203 at the output end of the metering pump 202, so that the polyferric sulfate agent is evenly sprinkled in the sewage tank 100. When the movable seat 103 moves, it drives the pressing rod 104 to press the top of the pressure head 303, and the pressure head 303 pushes the sliding rod 302 to slide on the inner wall of the column 301 and squeezes the water inside the column 301, so that the water is ejected through the top of the injection disc 306, and the water is impacted on the nearby water body while the water is ejected. When the injection disc 306 impacts the sewage inside the sewage tank 100 in turn, there is a large impact force between the wastewater, so that the sewage is mixed, thereby improving the mixing efficiency of the sewage and the polyferric sulfate agent;

[0046] When the movable seat 103 moves, it drives the support block 401 to move horizontally. At this time, the movable roller 402 is attached to the bottom of the sewage tank 100 and is caught inside the support block 401 by the friction force. When the movable roller 402 rotates, it drives the cleaning brush 403 to rotate. Since the bristles on the surface of the cleaning brush 403 are in an arc shape and fit with the top of the spray disc 306, the cleaning brush 403 brushes the surface of the spray disc 306 when it rotates, thereby preventing the spray port on the surface of the spray disc 306 from being blocked, thereby ensuring that the spray disc 306 is kept away from the dirt. 06 spray effect; the piston rod at the end of the control cylinder 505 drives the second rack 506 to move horizontally, and the second rack 506 drives the fixed gear 504 to rotate during the movement, so that the baffle 502 rotates on the surface of the fixed block 501, and stops rotating when the baffle 502 rotates to be vertical to the sewage. The baffle 502 blocks the sewage ripples in the impact and stirring, so that the sewage can be quickly calmed without external force, which is convenient for the suspended particles in the sewage to settle to the bottom of the water, thereby increasing the sewage treatment efficiency.

[0047] The second object of the present invention is to provide a method for processing and delivering polyferric sulfate for sewage treatment, comprising any one of the above-mentioned polyferric sulfate processing and delivering devices for sewage treatment, comprising the following steps:

[0048] S1. The output end of the rotating motor 101 drives the screw rod 102 to rotate, so that the movable seat 103 moves horizontally on the surface of the screw rod 102. When the movable seat 103 moves, the movable seat 103 drives the solution tank 201 to move horizontally above the sewage tank 100, and discharges the polyferric sulfate agent to the sewage in the sewage tank 100 through the infusion tube 203 at the output end of the metering pump 202, so that the polyferric sulfate agent is evenly sprinkled on the sewage in the sewage tank 100;

[0049] S2. When the moving seat 103 moves, it drives the pressing rod 104 to move horizontally, pressing the mixing assembly 300, so that the mixing assembly 300 aerates the sewage and impacts the sewage, so that the polyferric sulfate agent is quickly mixed with the sewage, thereby improving the agent mixing efficiency. At the same time, when the moving seat 103 moves, it drives the cleaning assembly 400 to move horizontally to brush the surface of the mixing assembly 300, thereby removing the sediment attached to the surface of the mixing assembly 300;

[0050] S3. After the polyferric sulfate agent is added, the shaking wastewater in the sewage tank 100 is quickly blocked and leveled by the leveling component 500, so that the suspended particles in the sewage are settled to the bottom of the water.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
