Description

Technical Field

[0001] This invention relates to the field of water pollution treatment equipment technology, specifically to a multi-element ozone catalytic water pollution treatment equipment. Background Technology

[0002] Water pollution treatment is a water conservancy technology that uses engineering and non-engineering methods to make wastewater meet the water quality requirements for discharge or reuse, and to improve or eliminate water pollution. It mainly targets industrial wastewater, agricultural wastewater, medical wastewater and other production wastewater and domestic sewage. Treatment technologies are divided into physical methods (sedimentation, filtration), chemical methods (coagulation, oxidation) and biological methods (activated sludge process, contact oxidation process). Commonly used equipment includes aerators, centrifuges, etc. The treated wastewater can be reused for industrial, agricultural and ecological water replenishment.

[0003] Among them, multi-element ozone catalytic oxidation is an advanced oxidation water treatment technology that uses multiple transition metal composite oxide catalysts to enhance ozone decomposition and generate strong oxidizing hydroxyl radicals on the basis of ordinary ozone catalysis. It is highly efficient in treating recalcitrant and highly toxic industrial wastewater, biochemical effluent, and surface water. It is a mainstream process for deep wastewater treatment. Its supporting equipment mainly includes: mechanical bar screen, equalization tank and submersible agitator, coagulation and dosing system, oxygen source ozone generator, ozone dosing system, catalytic oxidation reaction tower, etc.

[0004] Chinese patent document CN222312754U discloses a chemical wastewater pretreatment device for ozone oxidation, including a shell, an air pump at the top of the shell, an exhaust pipe at the top of the air pump, a ladder on the outside of the shell, a first water inlet pipe on the outside of the shell, a motor on one side of the shell, a second water inlet pipe on one side of the shell, a first drain pipe on the other side of the shell, a second drain pipe on the other side of the shell, and a stirring mechanism at one end of the motor.

[0005] When using the device, the medicine is first put into the inside of the shell through the feeding port. Then the motor is started, which drives the rotating shaft to rotate. The rotating shaft then drives the connecting rod to rotate. When the connecting rod rotates, the fixing plate on its outer side will drive the fixing plate to rotate. The fixing plate stirs the sewage inside the shell. During the stirring process, the middle section of the connecting rod will drive the rectangular plate to rotate, thereby realizing that the rectangular plate drives the sewage in the middle section of the shell to rotate.

[0006] In the above technology, the fixed plate and rectangular plate are rotated by the rotating shaft to mix the drug and sewage. During the mixing process, a large number of bubbles are generated inside the shell. It is difficult to quickly eliminate the bubbles on the liquid surface during the rotation of the fixed plate and rectangular plate, resulting in insufficient reaction between the drug and sewage and low sewage treatment efficiency. Summary of the Invention

[0007] This invention provides a multi-element ozone catalytic water pollution treatment equipment, aiming to solve the technical problem in the prior art where a rotating shaft drives a fixed plate and a rectangular plate to rotate, mixing drugs and sewage. During the mixing process, a large number of bubbles are generated inside the outer shell, and it is difficult to quickly eliminate the bubbles on the liquid surface during the rotation of the fixed plate and the rectangular plate, resulting in insufficient reaction between the drugs and sewage and low sewage treatment efficiency.

[0008] This invention discloses a multi-element ozone catalytic water pollution treatment equipment, comprising a treatment tank, a stirring rod disposed within the treatment tank, and stirring blades disposed on the stirring rod for stirring wastewater. The treatment tank is equipped with a defoaming device, which includes an mounting sleeve disposed on the stirring rod, multiple defoaming frames rotatably fitted onto the mounting sleeve, and an adjustment mechanism for adjusting the vertical rotation of the defoaming frames. The defoaming frames are inclined vertically upwards from one end near the mounting sleeve to the other end. The adjustment mechanism drives the defoaming frames to move, adjusting their inclination angle. When the stirring rod rotates, it drives the mounting sleeve and defoaming frames to rotate, thereby defoaming the air bubbles at the liquid surface.

[0009] Beneficial effects: By setting up a defoaming device, when it is necessary to eliminate bubbles in the treatment tank, the defoaming frame is rotated by the adjustment mechanism, and the tilt angle of the defoaming frame is adjusted. After the defoaming frame is rotated, the stirring rod can drive the installation sleeve and the defoaming frame to rotate. When the defoaming frame rotates, it defoams the bubbles on the liquid surface, making the reaction between the drug and the sewage more complete and improving the sewage treatment efficiency.

[0010] Preferably, the mounting sleeve slides vertically onto the stirring rod, and the adjustment mechanism includes a driver for raising and lowering the mounting sleeve and an adjustment component for raising and lowering one end of the defoaming frame away from the mounting sleeve. One end of the driver is mounted on the stirring rod, and the other end is connected to the mounting sleeve.

[0011] Preferably, the adjustment assembly includes an adjustment rod and a positioning float ring disposed on the defoaming frame. One end of the adjustment rod is rotatably engaged with the upper surface of the positioning float ring. The positioning float ring is disposed on the inner wall of the treatment tank. The liquid level near the inner wall of the treatment tank can push the positioning float ring to rise. The positioning float ring drives the defoaming frame to tilt and rotate through the adjustment rod.

[0012] Preferably, the processing tank is provided with a telescopic rod, which is vertically arranged and one end of the telescopic rod is connected to a positioning float ring.

[0013] Preferably, the defoaming frame includes a rotating part rotatably fitted onto the mounting sleeve and an adjusting part slidably fitted onto the rotating part along the radial direction of the stirring rod, the adjusting part being connected to the adjusting rod.

[0014] Beneficial effects: By setting up the rotating part and the adjusting part, when the positioning float ring drives the adjusting rod to move, the adjusting rod can drive the adjusting part to slide and adjust, thereby realizing the adjustment of the length of the defoaming rack, so as to meet the needs of defoaming racks of different lengths when rotating and adjusting.

[0015] Preferably, the lower surface of the defoaming frame is provided with a mounting plate, and the mounting plate is provided with defoaming needles for puncturing bubbles.

[0016] Preferably, the mounting plate is rotatably fitted to the defoaming frame along the length of the defoaming frame, and the defoaming frame is provided with a rotating device for driving the mounting plate to rotate.

[0017] Beneficial effects: By setting up a rotating device, the rotating device can drive the mounting plate to rotate, which in turn drives the defoaming needle to rotate. When the defoaming needle rotates, it can defoam the air bubbles present below the surface of the sewage, further improving the efficiency of air bubble treatment.

[0018] Preferably, the rotating device includes a rotating assembly for driving the mounting plate to rotate and a torsion spring for driving the mounting plate to reset. One end of the torsion spring is connected to the defoaming frame and the other end is connected to the mounting plate. The defoaming frame is provided with a flow port. The end of the flow port facing the direction of rotation of the stirring blade is designated as the large end and the other end is designated as the small end.

[0019] Preferably, the rotating assembly includes a support frame mounted on the defoaming frame, a rotating impeller rotatably fitted on the support frame, and a cam connected to the rotating impeller. After the sewage flows out from the large end of the flow port through the small end of the flow port, it drives the rotating impeller to rotate. The rotating impeller drives the cam to rotate, and the cam presses against the mounting plate, thereby driving the defoaming needle to rotate.

[0020] Preferably, a defoaming filter is provided at the small end of the flow port.

[0021] Beneficial effects: By setting up the defoaming filter, bubbles enter the flow port and are defoamed when they reach the defoaming filter.

[0022] The beneficial effects of this invention are as follows: 1. In this invention, by setting up a defoaming device, when it is necessary to eliminate bubbles in the treatment tank, the defoaming frame is rotated by an adjusting mechanism to adjust the tilt angle of the defoaming frame. After the defoaming frame is adjusted, when the stirring rod rotates, it can drive the mounting sleeve and the defoaming frame to rotate. When the defoaming frame rotates, it defoams the bubbles at the liquid surface, making the reaction between the drug and the sewage more complete and improving the sewage treatment efficiency. In addition, during the mixing process, the liquid surface is in the form of a conical vortex with a "low center and high edge". At this time, one end of the defoaming frame actively descends, and the other end is pushed up by the buoyancy provided by the liquid surface. During the mixing process, when the height of the liquid surface changes, such as when the stirring speed, liquid viscosity and other working conditions change and the tilt angle of the vortex changes, the height of the liquid surface at the edge of the inner wall of the tank will change synchronously. The positioning float ring will automatically rise or fall with the height of the liquid surface. The adjusting rod drives the defoaming frame to move, and the length of the defoaming frame changes to match the change of the tilt angle of the liquid surface in real time.

[0023] 2. In this invention, by setting the defoaming needles, when the lower surface of the defoaming frame gradually rises from the center to the edge, which corresponds to different depth areas below the liquid surface from the center to the edge, the defoaming needles set on the lower surface of the defoaming frame are also inclined, and their needle tips just extend into the bubble-rich area below the liquid surface to puncture the suspended bubbles below the liquid surface. The defoaming frame body is used to break large bubbles at the liquid surface. The two work together to further improve the bubble elimination effect. Attached Figure Description

[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] Reference Figures 1-7 This invention discloses a multi-element ozone catalytic water pollution treatment equipment, comprising a treatment tank 1, a stirring rod 2 disposed within the treatment tank 1, stirring blades 3 fixedly disposed on the stirring rod 2 for stirring wastewater, and a defoaming device 4 disposed within the treatment tank 1. The top of the treatment tank 1 is provided with multiple filling ports for adding wastewater and other materials (such as drugs or agents), and the bottom of the treatment tank 1 is provided with a discharge port for discharging treated wastewater. A control valve for controlling the opening and closing of the discharge port is fixedly installed at the discharge port. The stirring rod 2 is vertically arranged and rotatably engaged within the treatment tank 1. The defoaming device 4 is used to defoam the bubbles generated during wastewater treatment within the treatment tank 1. A driving component is fixedly installed on the top of the treatment tank 1. 9. The drive unit 9 is directly powered by an electric motor. The housing of the drive unit 9 is fixedly mounted on the treatment tank 1. The output shaft of the drive unit 9 is fixedly connected to the stirring rod 2. The drive unit 9 is used to drive the stirring rod 2 to rotate. When sewage needs to be treated, sewage and other materials are first added to the treatment tank 1 through multiple filling ports. After the addition is completed, the drive unit 9 starts working, driving the stirring rod 2 to rotate. The stirring rod 2 drives the stirring blades 3 and the defoaming device 4 to rotate. During the rotation of the stirring blades 3, the sewage and the medicine are mixed. During the rotation of the defoaming device 4, the bubbles inside the treatment tank 1 are defoamed. After the sewage and the medicine are mixed, the drive unit 9 is turned off. Then the treated sewage is discharged through the discharge port, completing the sewage treatment operation.

[0034] Reference Figure 2 , Figure 3 and Figure 4The defoaming device 4 includes an mounting sleeve 41 mounted on the stirring rod 2, multiple defoaming frames 42 rotatably fitted on the mounting sleeve 41, and an adjustment mechanism for adjusting the rotation of the defoaming frames 42 in the vertical direction. The mounting sleeve 41 is an annular structure and is slidably fitted to the stirring rod 2 in the vertical direction. When the stirring rod 2 rotates, it can drive the mounting sleeve 41 to rotate. The defoaming frames 42 are inclined vertically upward from one end near the mounting sleeve 41 to the other end. When it is necessary to defoam the bubbles, the adjustment mechanism is first used to move the defoaming frames 42 to adjust the inclination angle of the defoaming frames 42. Then, when the stirring rod 2 rotates, it drives the mounting sleeve 41 and the defoaming frames 42 to rotate, thereby defoaming the bubbles at the liquid surface.

[0035] Among them, reference Figure 2 , Figure 3 and Figure 5 The defoaming frame 42 includes a rotating part 421 rotatably fitted on the mounting sleeve 41 and an adjusting part 422 slidably fitted on the rotating part 421 along the radial direction of the stirring rod 2. Both the rotating part 421 and the adjusting part 422 are hollow structures and are made of lightweight metal materials (such as aluminum alloy). A rotating seat is fixedly installed on the mounting sleeve 41, and the rotating part 421 is rotatably fitted with the mounting sleeve 41 through the rotating seat. When the adjusting part 422 slides along the length direction of the rotating part 421, the length of the defoaming frame 42 can be adjusted.

[0036] Reference Figure 2 , Figure 3 and Figure 5 The adjustment mechanism includes a driver 43 for raising and lowering the mounting sleeve 41 and an adjustment component 44 for raising and lowering the end of the defoaming frame 42 away from the mounting sleeve 41. The driver 43 can be a hydraulic cylinder. The driver 43 is set vertically, with one end fixedly mounted on the stirring rod 2 and the other end fixedly connected to the mounting sleeve 41. When the driver 43 is started, the mounting sleeve 41 can be slidably adjusted along the stirring rod 2 to make a preliminary adjustment to the position of the mounting sleeve 41. This allows the driver 43 to be initially positioned according to the tank volume and the expected amount of filling material, so that the center end of the defoaming frame 42 is approximately at the center height of the liquid vortex.

[0037] Reference Figure 2 , Figure 3 and Figure 5The adjusting assembly 44 includes an adjusting rod 441 and a positioning float 442 mounted on the defoaming frame 42. One end of the adjusting rod 441 is fixedly connected to the adjusting part 422, and the other end of the adjusting rod 441 is rotatably fitted onto the upper surface of the positioning float 442. A rotating seat may be provided on the positioning float 442, and the adjusting rod 441 is rotatably fitted with the rotating seat. The positioning float 442 is located on the inner wall of the treatment tank 1. The positioning float 442 is made directly from a lightweight material. With a hollow structure, when the liquid level near the inner wall of the treatment tank 1 rises, the buoyancy of the liquid on the positioning float 442 is greater than the weight of the positioning float 442 itself, thus pushing the positioning float 442 to rise. The positioning float 442 drives the defoaming frame 42 to tilt and rotate via the adjusting rod 441. Conversely, when the liquid level near the inner wall of the treatment tank 1 falls, the buoyancy of the liquid on the positioning float 442 is less than the weight of the positioning float 442 itself, and the positioning float 442 falls with the liquid level.

[0038] Reference Figure 2 and Figure 3 The treatment tank 1 is equipped with a telescopic rod 5, which is vertically positioned. One end of the telescopic rod 5 is connected to the positioning float 442, and the other end is connected to the treatment tank 1. The telescopic rod 5 can be adjusted vertically to ensure that the positioning float 442 can only move vertically. When defoaming is required, the driver 43 is activated, which drives the mounting sleeve 41 to descend. As the mounting sleeve 41 descends, it also drives one end of the rotating part 421 to descend. Simultaneously, the liquid level near the inner wall of the treatment tank 1 provides buoyancy to the positioning float 442, causing it to be positioned above the mounting sleeve 41. During the upward movement of the positioning float 442... In the process, the positioning float 442 can drive one end of the adjusting rod 441 to rise and rotate simultaneously. The adjusting rod 441 drives the adjusting part 422 to move. One end of the rotating part 421 descends and rotates simultaneously, driving the adjusting part 422 to move synchronously. At this time, the adjusting part 422 and the rotating part 421 move away from each other. After the defoaming frame 42 is tilted and adjusted, the driver 43 is turned off. At this time, the tilt angle of the defoaming frame 42 is matched with the tilt angle of the sewage surface. When the positioning float 442 descends, it can drive one end of the adjusting rod 441 to descend and rotate simultaneously. The adjusting rod 441 drives the adjusting part 422 to move simultaneously. At this time, the adjusting part 422 and the rotating part 421 move closer to each other.

[0039] Reference Figure 2 , Figure 5 and Figure 6 The defoaming frame 42 is provided with a flow port 423. The flow port 423 is a conical structure. One end of the flow port 423 facing the direction of rotation of the stirring blade 3 is a large end, and the other end is a small end. A defoaming filter 8 is fixedly installed at the small end of the flow port 423. The defoaming filter 8 is set vertically.

[0040] Reference Figure 5 , Figure 6 and Figure 7 The lower surface of the defoaming frame 42 is provided with a mounting plate 6. The mounting plate 6 is arranged along the length direction of the defoaming frame 42 and is rotatably fitted to the defoaming frame 42 along the length direction of the defoaming frame 42. The mounting plate 6 includes a fixing part and a sliding part that is slidably fitted to the fixing part along the length direction of the defoaming frame 42. A defoaming needle 61 for puncturing bubbles at a certain depth below the liquid surface is fixedly provided on the mounting plate 6. The defoaming needle 61 adopts a smooth, fine needle-like structure.

[0041] Reference Figure 2 , Figure 4 and Figure 6 The defoaming rack 42 is equipped with a rotating device 7 for driving the mounting plate 6 to rotate, combined with Figure 7 The rotating device 7 includes a rotating assembly 71 for driving the mounting plate 6 to rotate and a torsion spring 72 for driving the mounting plate 6 to return to its original position. One end of the torsion spring 72 is fixedly connected to the defoaming frame 42, and the other end is fixedly connected to the mounting plate 6. The rotating assembly 71 includes a support frame 711 fixedly mounted on the defoaming frame 42, a rotating impeller 712 rotatably fitted on the support frame 711, and a cam 713 connected to the rotating impeller 712. The rotating impeller 712 includes a rotating shaft rotatably fitted on the support frame 711 and multiple rotating blades fixedly mounted on the outer circumferential surface of the rotating shaft. The cam 713 has two protruding ends, which are diagonally positioned at the two corners of the cam 713. The cam 713 is fixedly connected to the rotating shaft, and the protruding ends on the cam 713 can abut against the mounting plate 6 and press against it. When the defoaming frame 42 rotates, wastewater can flow into the defoaming frame 42 from the large end of the flow port 423. The wastewater flows out through the small end of the flow port 423. When the wastewater flows out, it drives the rotating impeller 712 to rotate. The rotating impeller 712 drives the cam 713 to rotate. The protruding end on the cam 713 can squeeze the mounting plate 6, causing the mounting plate 6 to rotate and compressing the torsion spring 72. When the mounting plate 6 rotates, it can drive the defoaming needle 61 to rotate. The defoaming needle 61 defoams the air bubbles. When the protruding end on the cam 713 passes the mounting plate 6, the cam 713 no longer squeezes the mounting plate 6. At this time, the torsion spring 72 releases its elastic restoring force, driving the mounting plate 6 to reset and rotate. The mounting plate 6 drives the defoaming needle 61 to reset. After the mounting plate 6 and the defoaming needle 61 are reset, the protruding end on the cam 713 can continue to squeeze the mounting plate 6 and drive the mounting plate 6 to rotate, thereby realizing the cyclic reciprocating oscillation of the defoaming needle 61. This reciprocating oscillation is a small-amplitude, high-frequency reciprocating oscillation, which defoams the air bubbles below the surface of the wastewater.

[0042] The implementation principle of the multi-element ozone catalytic water pollution treatment equipment of the present invention is as follows: When sewage needs to be treated, sewage and other materials are first added to the treatment tank 1 through multiple filling ports. After the addition is completed, the sewage and the medicine are mixed. During the mixing, the driving component 9 works, the driving component 9 drives the stirring rod 2 to rotate, and the stirring rod 2 drives the stirring blade 3, the mounting sleeve 41 and the defoaming frame 42 to rotate. Next, start the driver 43. The driver 43 can drive the mounting sleeve 41 to descend. When the mounting sleeve 41 descends, it drives one end of the rotating part 421 to descend. At the same time, since the liquid surface of the sewage near the inner wall of the treatment tank 1 can provide buoyancy for the positioning float ring 442, the positioning float ring 442 is located above the mounting sleeve 41. During the upward floating process of the positioning float ring 442, the positioning float ring 442 can drive one end of the adjusting rod 441 to rise and rotate at the same time. The adjusting rod 441 drives the adjusting part 422 to move. The rotating part 421 rotates while descending near the stirring rod 2, which can drive the adjusting part 422 to move synchronously. The adjusting part 422 and the rotating part 421 move away from each other. When the defoaming frame 42 is tilted and adjusted, the driver 43 is turned off. At this time, the tilt angle of the defoaming frame 42 is matched with the tilt angle of the sewage liquid surface. During the rotation of the stirring blade 3, the wastewater and the medicine are mixed, and during the rotation of the defoaming rack 42, the air bubbles inside the treatment tank 1 are defoamed. Meanwhile, as the defoaming frame 42 rotates, wastewater can flow into the defoaming frame 42 from the large end of the flow port 423 and flow out through the small end of the flow port 423. After the wastewater flows out, it can drive the rotating impeller 712 to rotate. The rotating impeller 712 drives the cam 713 to rotate. The protruding end on the cam 713 can squeeze the mounting plate 6, causing the mounting plate 6 to rotate and compressing the torsion spring 72. When the mounting plate 6 rotates, it can drive the defoaming needle 61 to rotate. The defoaming needle 61 defoams the bubbles. When the protruding end on the cam 713 passes the mounting plate 6, the cam 713 no longer squeezes the mounting plate 6. At this time, the torsion spring 72 releases its elastic restoring force, driving the mounting plate 6 to reset and rotate. The mounting plate 6 drives the defoaming needle 61 to reset. When the mounting plate 6 and the defoaming needle 61 are reset, the protruding end on the cam 713 can continue to squeeze the mounting plate 6 and drive the mounting plate 6 to rotate, thereby realizing the cyclical oscillation of the defoaming needle 61 to defoam the bubbles below the surface of the wastewater. After the sewage treatment is completed, the drive unit 9 is turned off, and then the treated sewage is discharged through the discharge port, completing the sewage treatment operation.

[0043] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
