Description

Technical Field

[0001] The present invention relates to the field of wastewater treatment, and more particularly, to a disinfection tank for wastewater treatment. Background Art

[0002] Wastewater treatment refers to the removal of pollutants contained in wastewater through a series of technical means to meet the discharge standards or reuse requirements. The process of wastewater treatment usually includes several stages such as physical treatment, chemical treatment, and biological treatment. The disinfection of wastewater is the last link in the whole treatment process, and its main purpose is to eliminate pathogenic microorganisms (such as bacteria, viruses, and parasites, etc.) that may exist in the wastewater to ensure that the water discharged into the environment or reused will not pose a threat to public health.

[0003] During the wastewater disinfection process, fungicides are used. Commonly used chemical disinfectants include chlorine and its compounds, chlorine dioxide, ozone, hydrogen peroxide, and bromine, etc. Among them, chlorine-based disinfectants (such as sodium hypochlorite, chlorine gas) have become one of the most commonly used wastewater disinfection methods due to their high efficiency and economy. However, due to their high chemical stability, these disinfectants can maintain their effectiveness for a long time during use and are not easily decomposed or degraded under natural water body conditions. Although chlorine-based disinfectants will undergo a series of chemical reactions in wastewater, they will not be completely consumed, and part of them will remain in the treated wastewater in a dissolved form. In addition, by-products (such as trihalomethanes and haloacetic acids, etc.) generated by the reaction of chlorine with organic matter in wastewater will also remain. These unreacted chlorine components and their by-products will not only cause harm to the ecological environment but also pose a threat to human health. Summary of the Invention

[0011] Further, a circular plate is fixedly installed in the inner cavity of the sleeve frame, a T-shaped rod is slidably installed on the circular plate, a return spring is fixedly installed between the T-shaped rod and the circular plate, magnet blocks are fixedly installed at the bottom end of the T-shaped rod and the top end of the square rod respectively, the two magnet blocks are magnetically attracted and installed, and the two magnet blocks and the T-shaped rod are all slidably installed in the inner cavity of the sleeve frame.

[0012] Further, a mounting pipe is fixedly installed on one side of the top of the disinfection tank, the mounting pipe is communicated with the inner cavity of the disinfection tank, a blocking block is slidably installed in the inner cavity of the mounting pipe, and a telescopic spring is fixedly installed between the blocking block and the inner cavity top wall of the mounting pipe.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) In this solution, the heating plate is used to heat the wastewater and the fungicide in the disinfection tank. While the stirring rod rotates, it will move up and down. This way can better break the liquid stratification phenomenon, ensure that the fungicide is more evenly distributed in the whole water body, make the fungicide contact with the target microorganisms faster and play a role, so as to shorten the required treatment time. At the same time, it improves the fluidity of the wastewater and the fungicide, helps to maintain the consistency of the temperature in the disinfection tank, and can better transfer the heat to the whole water body to achieve faster and more uniform temperature rise. Through heating combined with efficient mixing, the process of the fungicide decomposing into active ingredients can be accelerated, reducing the problems of too high or too low local concentration caused by uneven distribution, thereby reducing the generation of unreacted fungicide residues and potential pollutants, and further improving the disinfection efficiency.

[0020] (2) In this solution, during the up-and-down movement of the movable plate, the gas in the inner cavity of the disinfection tank can be reciprocally extracted by the movable plate and discharged into the wastewater. This way can reintroduce the unreacted active ingredients contained in the waste gas into the wastewater, increase the opportunity for these active ingredients to contact the wastewater, avoid waste of resources, improve the overall utilization rate of the fungicide and the disinfection effect. At the same time, by contacting the inner cavity wall of the disinfection tank with the exhaust pipe, the cylinder drives the exhaust pipe to rotate, which can help to remix the liquid attached to the container wall into the main fluid, ensuring that all components can fully contact and participate in the reaction. This helps to improve the mixing uniformity between the fungicide and the wastewater, thereby enhancing the disinfection effect, and can reduce the possibility of bacteria or other microorganisms growing on the surface, and further reduce the risk of secondary pollution.

[0021] (3) When the cylinder rotates in this solution, it will drive each group of cross plates on it to rotate through the sleeve plate. Through the cooperation of the rolling balls and the wave grooves, the cross plates can move up and down during rotation. Through the rotation and up-and-down movement of the cross plates, the unreacted gas components can be more evenly distributed in the disinfection tank. This helps to avoid gas accumulation and form local high-concentration areas, ensuring that the gas extracted each time has similar components and concentrations, so that it can participate in the disinfection process more effectively. This can not only reduce the waste of disinfectant but also improve the overall disinfection effect. Description of the Drawings

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 7 , a disinfection tank for wastewater treatment, including a disinfection tank 1, and a liquid inlet 2 is fixedly installed on one side of the disinfection tank 1;

[0033] It further includes:

[0034] A quick decomposition component, the quick decomposition component includes a heating plate 3 fixedly installed on the bottom wall of the inner cavity of the disinfection tank 1, a square rod 4 is rotatably installed on the bottom wall of the inner cavity of the disinfection tank 1, a sleeve frame 5 is sleeved on the outer side of the square rod 4, a cylinder 6 is rotatably installed on the top wall of the inner cavity of the disinfection tank 1, a reciprocating lead screw 7 is arranged in the inner cavity of the cylinder 6, the reciprocating lead screw 7 is rotatably installed with both the disinfection tank 1 and the cylinder 6, a movable plate 8 is slidably installed in the inner cavity of the cylinder 6, the movable plate 8 is threadedly installed with the reciprocating lead screw 7, two vertical rods 9 are fixedly installed at the bottom of the movable plate 8, the bottom ends of the two vertical rods 9 both penetrate through the cylinder 6 and are fixedly installed with the top of the sleeve frame 5, the two vertical rods 9 are both slidably installed with the cylinder 6, stirring rods 21 are evenly fixedly installed on the outer wall of the sleeve frame 5, and a driving component is arranged at the top wall of the inner cavity of the disinfection tank 1.

[0035] The driving component includes a gear one 10 rotatably installed on the top wall of the inner cavity of the disinfection tank 1, the gear one 10 is arranged inside the cylinder 6, a gear two 11 is fixedly installed on the rod wall of the reciprocating lead screw 7, the gear two 11 is meshed and installed with the gear one 10, teeth 12 are evenly fixedly installed on the inner cavity wall of the cylinder 6, the gear one 10 is meshed and installed with the adjacent liquid inlet 2, air inlet holes 13 are evenly opened on the movable plate 8, air suction holes 14 are evenly opened on the side wall of the cylinder 6 near the top, exhaust pipes 15 are evenly fixedly installed on the side wall of the cylinder 6 near the bottom, the bottom end of each exhaust pipe 15 extends to the bottom wall of the inner cavity of the disinfection tank 1, and each exhaust pipe 15 is in contact with the inner cavity wall of the disinfection tank 1, teeth 12 are fixedly installed at the bottom of the disinfection tank 1, and the output end of the teeth 12 is fixedly installed with the square rod 4.

[0036] First, connect the pipeline on the liquid inlet device 2 to the container filled with the bactericide. Then, pour the wastewater to be disinfected into the disinfection tank 1 through the liquid inlet pipe on one side of the top of the disinfection tank 1. After pouring, seal the liquid inlet pipe to make the inside of the disinfection tank 1 in a sealed state. Start the gear teeth 12. The output end of the gear teeth 12 will drive the sleeve frame 5 to rotate through the square rod 4. While the sleeve frame 5 rotates, it will drive each group of stirring rods 21 on it to rotate synchronously, so as to realize the rotation of the stirring rods 21 to stir the wastewater in the disinfection tank 1. At this time, appropriately extract the bactericide in the container through the liquid inlet device 2 and discharge it into the wastewater in the disinfection tank 1. Through the stirring of the stirring rods 21, the bactericide can be fully mixed in the wastewater. Start the heating plate 3. The heating plate 3 can heat the wastewater and the bactericide in the disinfection tank 1. While the sleeve frame 5 rotates, it will also drive the cylinder 6 and the movable plate 8 to rotate synchronously through the vertical rod 9. While the cylinder 6 rotates, it will drive each group of gear teeth 12 inside it to rotate synchronously, so as to realize the cylinder 6 driving the gear one 10 to rotate in the same direction through the gear teeth 12. While the gear one 10 rotates, it will drive the gear two 11 to rotate in the opposite direction. While the gear two 11 rotates, it will drive the reciprocating lead screw 7 to rotate synchronously. At this time, it can be realized that while the cylinder 6 drives the movable plate 8 to rotate, the reciprocating lead screw 7 rotates in the opposite direction. The reverse rotation of the reciprocating lead screw 7 and the movable plate 8 can make the movable plate 8 quickly move up and down on the rod wall of the reciprocating lead screw 7. While the movable plate 8 moves up and down, it will drive the sleeve frame 5 to move up and down on the outer wall of the square rod 4 through the vertical rod 9. While the sleeve frame 5 moves up and down, it will drive each group of stirring rods 21 on it to move synchronously. At this time, it can be realized that each group of stirring rods 21 will move up and down while rotating. This way can better break the liquid stratification phenomenon, ensure that the bactericide is more evenly distributed in the whole water body, make the bactericide contact the target microorganisms faster and play a role, so as to shorten the required treatment time. At the same time, it improves the fluidity of the wastewater and the bactericide, helps to maintain the consistency of the temperature in the disinfection tank 1, and can better transfer the heat to the whole water body to realize faster and more uniform heating. Through heating combined with efficient mixing, the process of the bactericide decomposing into active ingredients can be accelerated, reducing the problems of too high or too low local concentration caused by uneven distribution, thereby reducing the generation of unreacted bactericide residues and potential pollutants, and further improving the disinfection efficiency;

[0037] During the process of mixing and disinfecting the fungicide with the wastewater, waste gas or by-products will be generated, which will contain unreacted components. These gases will be placed in the space above the wastewater in the disinfection tank 1. Check valves are installed in the air inlet hole 13, the suction hole 14, and the exhaust pipe 15. The gas in the disinfection tank 1 can only enter the cylinder 6 through the square rod 4. The gas in the cylinder 6 above the movable plate 8 can only be discharged to the lower side of the movable plate 8 through the air inlet hole 13. The gas in the cylinder 6 below the movable plate 8 can only be discharged through the exhaust pipe 15, and the gas cannot flow back. During the up and down movement of the movable plate 8, when the movable plate 8 moves upward, the movable plate 8 will squeeze the gas in the inner cavity of the cylinder 6 above it in the disinfection tank 1 to be discharged into the cylinder 6 on the lower side of the movable plate 8 through the air inlet hole 13. When the movable plate 8 moves downward, the movable plate 8 will squeeze the gas in the inner cavity of the cylinder 6 below it into each group of exhaust pipes 15. These gases will be discharged into the wastewater through the bottom end of the exhaust pipe 15. At the same time, the movable plate 8 will extract the gas in the inner cavity of the disinfection tank 1 through the suction hole 14 and discharge it into the inner cavity of the cylinder 6 above the movable plate 8. At this time, during the up and down movement of the movable plate 8, the movable plate 8 can reciprocally extract the gas in the inner cavity of the disinfection tank 1 and discharge it into the wastewater. This method can reintroduce the unreacted effective components in the waste gas, such as uncompletely dissolved chlorine, into the wastewater, increase the contact opportunity between these effective components and the wastewater, avoid waste of resources, thereby improving the overall utilization rate of the fungicide and further improving the disinfection effect;

[0038] At the same time, by contacting the inner cavity wall of the disinfection tank 1 through the exhaust pipe 15, the cylinder 6 can drive the exhaust pipe 15 to help remix the liquid attached to the container wall into the main fluid during rotation, ensuring that all components can fully contact and participate in the reaction. This helps to improve the mixing uniformity between the fungicide and the wastewater, thereby enhancing the disinfection effect, and can reduce the possibility of bacteria or other microorganisms growing on the surface, and further reduce the risk of secondary pollution.

[0039] As Figure 3 and Figure 4 shown, the outer wall of the cylinder 6 is evenly and slidably installed with a sleeve plate 16. The outer walls of each group of sleeve plates 16 are evenly and fixedly installed with a cross plate 17. One group of cross plates 17 in the horizontal direction are fixedly installed with a cylinder 18 on the side close to the inner wall of the disinfection tank 1. One end of each group of cylinders 18 close to the inner wall of the disinfection tank 1 is rotatably installed with a ball 19. The inner wall of the disinfection tank 1 is evenly provided with a wave groove 20 adapted to the ball 19.

[0040] While the cylinder 6 is rotating, it will drive the cross plates 17 on it to rotate synchronously through the sleeve plate 16. The cross plates 17 with cylinders 18 will drive the cylinders 18 to move synchronously while rotating. While the cylinders 18 are moving, they will drive the balls 19 to move in the inner cavity of the wave groove 20. Through the setting of the wave groove 20 itself, it can be realized that as the balls 19 move along the path of the wave groove 20, they will drive the cylinders 18 to move up and down during the movement. While the cylinders 18 are moving, they will drive the sleeve plate 16 to move synchronously through the cross plates 17. At this time, it can be realized that while the cylinder 6 drives the cross plates 17 to rotate through the sleeve plate 16, the cross plates 17 will also move up and down. Through the rotation and up and down movement of the cross plates 17, the unreacted gas components can be more evenly distributed in the disinfection tank 1, which helps to avoid the formation of local high-concentration areas due to gas aggregation, ensures that the gas extracted each time has similar components and concentrations, and thus can participate more effectively in the disinfection process, not only reducing the waste of the fungicide but also improving the overall disinfection effect.

[0041] As Figure 5 shown, a circular plate 22 is fixedly installed in the inner cavity of the sleeve frame 5. A T-shaped rod 23 is slidably installed on the circular plate 22. A return spring 24 is fixedly installed between the T-shaped rod 23 and the circular plate 22. Magnet blocks 25 are fixedly installed at the bottom end of the T-shaped rod 23 and the top end of the square rod 4 respectively. The two magnet blocks 25 are magnetically installed, and the two magnet blocks 25 and the T-shaped rod 23 are all slidably installed in the inner cavity of the sleeve frame 5.

[0042] In the initial state, two sets of magnet blocks 25 are magnetically attracted to each other, and the return spring 24 is in a compressed state. When the movable plate 8 drives the vertical rod 9 to move upward, the vertical rod 9 will drive the circular plate 22 to move upward through the sleeve frame 5 and compress the return spring 24. When the return spring 24 is compressed beyond the magnetic attraction of the two sets of magnet blocks 25, the sleeve frame 5 continues to move upward will drive the upper magnet block 25 to move upward and away from the lower magnet block 25. At this time, under the action of the return spring 24, the return spring 24 returns to its initial state and pushes the T-shaped rod 23 upward to the initial position, realizing that the T-shaped rod 23 will hit the inner cavity top wall of the sleeve frame 5. When the sleeve frame 5 moves downward and the two sets of magnet blocks 25 enter the magnetic attraction range, the lower magnet block 25 will adsorb the upper magnet block 25 and move downward to be magnetically attracted together. When the upper magnet block 25 moves downward, it will drive the T-shaped rod 23 to move downward and away from the inner cavity of the sleeve frame 5, and at the same time squeeze the return spring 24 downward. At this time, during the up and down movement of the sleeve frame 5, the T-shaped rod 23 can reciprocally hit the inner cavity top wall of the sleeve frame 5 and generate vibrations. The shock waves will be transmitted to each stirring rod 21, and on the basis of the stirring of the stirring rod 21, vibrating it can generate complex flow patterns in the liquid, such as eddy currents, turbulence, etc. This helps to break the boundaries between liquid layers, making the contact between the wastewater and the bactericide more sufficient, thereby improving the mixing uniformity. Through more thorough mixing and faster reaction rates, the amount of bactericide input can be utilized to the maximum extent, further reducing the residue of unreacted components.

[0043] As Figure 6 shown, on one side of the top of the disinfection tank 1, an installation pipe 26 is fixedly installed. The installation pipe 26 is communicated with the inner cavity of the disinfection tank 1. A plugging block 28 is slidably installed in the inner cavity of the installation pipe 26. A telescopic spring 29 is fixedly installed between the plugging block 28 and the inner cavity top wall of the installation pipe 26.

[0044] Exhaust holes 30 are evenly arranged on the outer side of the plugging block 28, and each group of exhaust holes 30 is opened on the side wall of the installation pipe 26.

[0045] A purification frame 27 is arranged on the outer side of the installation pipe 26. The purification frame 27 is fixedly installed on the top of the disinfection tank 1. An activated carbon layer 31 is arranged above the installation pipe 26, and the activated carbon layer 31 is fixedly installed on the inner cavity wall of the purification frame 27.

[0046] During the wastewater disinfection process, since the disinfection is carried out in a sealed environment, the internal pressure of the disinfection tank 1 will increase due to the generation of waste gas or by-products. When the pressure in the disinfection tank 1 increases, it will push the plugging block 28 to move upward in the inner cavity of the installation pipe 26 and squeeze the telescopic spring 29. When the bottom of the plugging block 28 moves higher than the bottom of the inner cavity of the exhaust hole 30, the gas in the inner cavity of the disinfection tank 1 will be discharged into the purification frame 27 through the exhaust hole 30. The harmful substances in the gas entering the purification frame 27 will be adsorbed and purified by the activated carbon layer 31 and then discharged into the air. When the pressure in the disinfection tank 1 returns to normal after the gas is discharged, under the action of the telescopic spring 29, the telescopic spring 29 will return to its initial state and push the plugging block 28 to move downward to the initial position, which can block the exhaust hole 30 by the plugging block 28 and play a role in automatic air release.

[0047] As Figure 3 and Figure 5 shown, a ventilation pipe 32 is fixedly installed on one side wall of the disinfection tank 1, and a fan 33 is fixedly installed in the inner cavity of the ventilation pipe 32.

[0048] In the initial state, the reset spring 24 is in a compressed state, and the magnetic attraction of the two magnet blocks 25 is greater than the elastic force of the reset spring 24.

[0049] The range of the up and down movement of the movable plate 8 is between the air inlet hole 14 and the exhaust pipe 15.

[0050] When the wastewater disinfection in the disinfection tank 1 is completed, before opening the disinfection tank 1 to discharge the wastewater, since there will be residual waste gas or other by-products in the disinfection tank 1, at this time, the fan 33 is turned on and the valve in the ventilation pipe 32 is opened to make the ventilation pipe 32 communicate with the inside of the disinfection tank 1. The fan 33 will work to suck the outside air through the ventilation pipe 32 and then discharge it into the disinfection tank 1. The gas discharged into the disinfection tank 1 will increase the pressure in the disinfection tank 1 again. The gas in the disinfection tank 1 will be discharged into the purification frame 27 through the exhaust hole 30 again and discharged after being purified by the activated carbon layer 31. By the fan 33, the residual waste gas in the disinfection tank 1 can be blown out. After the blowing is completed, the wastewater in the disinfection tank 1 can be discharged through the pipe on one side of the bottom of the disinfection tank 1 to ensure safe operation and the safety of the maintenance working environment.

[0051] Working principle: First, pour the wastewater to be disinfected into the disinfection tank 1 through the liquid inlet pipe on one side of the top of the disinfection tank 1. Then, start the toothed teeth 12 to drive the sleeve frame 5 to rotate through the square rod 4, so that the stirring rod 21 stirs the wastewater. Start the liquid injector 2 to extract an appropriate amount of bactericide for the wastewater and discharge it into the disinfection tank 1 to mix with the wastewater. Start the heating plate 3 to heat the wastewater and bactericide in the disinfection tank 1 to promote the decomposition of the bactericide. When the sleeve frame 5 rotates, it will drive the toothed teeth 12 to rotate through the cylinder 6, so that the first gear 10 drives the reciprocating screw rod 7 to rotate rapidly in the reverse direction through the second gear 11. At this time, the movable plate 8 will drive the stirring rod 21 to move up and down through the sleeve frame 5 to uniformly mix the wastewater and bactericide in the disinfection tank 1. During the mixing process of the wastewater and the bactericide, incompletely reacted gas will be discharged above the liquid level. The up and down movement of the movable plate 8 will reciprocally extract the incompletely reacted gas and discharge it into the wastewater again to further promote the reaction. During the rotation of the cylinder 6, it will drive the cross plate 17 to rotate. Through the cooperation of the ball 19 and the wave groove 20, the cross plate 17 will move up and down during the rotation, which can make the components of the incompletely reacted gas more evenly distributed, so as to extract it more effectively to participate in the disinfection process. During the up and down movement of the sleeve frame 5, under the cooperation of the two magnet blocks 25 and the return spring 24, the T-shaped rod 23 will impact the sleeve frame 5, making the stirring rod 21 vibrate, further promoting the mixing effect of the wastewater and the bactericide. When the gas pressure in the disinfection tank 1 increases, the gas will automatically be discharged into the purification frame 27 through the exhaust hole 30 for purification and then discharged. When the wastewater disinfection is completed, blow air into the disinfection tank 1 through the blower 33, so that the remaining harmful gas inside can be blown into the purification frame 27 for purification and then discharged. After completion, the wastewater in the disinfection tank 1 can be discharged.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
