Description

Technical Field

[0001] The present invention relates to the technical field of biodegradation of organic pollutants, and particularly to a mixing device for biodegradation of organic pollutants. Background Art

[0002] With the rapid development of industrialization and urbanization, the problem of organic pollutant pollution in the environment has become increasingly serious. These pollutants not only affect the quality of water bodies and soil, but also pose a threat to human health. To address this challenge, people have been searching for effective methods to treat these pollutants. Among them, biodegradation, as an environmentally friendly and efficient treatment method, has received extensive attention in recent years. This method uses the metabolic action of microorganisms to convert organic pollutants into harmless or low-toxic substances, and has advantages such as high cost-effectiveness and environmental friendliness.

[0003] Although the biodegradation technology shows great potential, there are still some challenges in its practical application. In existing sewage treatment systems, the traditional method is to manually add a solution containing microorganisms to the sewage, and then achieve the mixing of microorganisms and pollutants through the natural diffusion process. However, due to the slow natural diffusion rate, it is difficult to achieve a uniform distribution of microorganisms in the sewage, resulting in too high a concentration of microorganisms in some areas while too low in other areas. This non-uniformity limits the overall efficiency of biodegradation, and in order to achieve an ideal mixing effect, it is necessary to wait for a long time for the microorganisms to naturally diffuse throughout the water body, which greatly increases the treatment cycle and reduces the overall efficiency of sewage treatment. Summary of the Invention

[0004] In view of this, the present invention provides a mixing device for biodegradation of organic pollutants, which can solve the drawbacks that when manually pouring a solution containing microorganisms into sewage and using the natural diffusion process to achieve the mixing of microorganisms and pollutants, not only is it difficult to achieve a uniform distribution of microorganisms in the sewage, but also the treatment cycle is greatly increased and the overall efficiency of sewage treatment is reduced.

[0005] The technical solution of the present invention is as follows: A mixing device for biodegradation of organic pollutants includes a liquid storage barrel for loading sewage.

The connecting rod 4 and the connecting plates 5 are both located inside the liquid storage barrel 1. By driving the connecting rod 4 and the connecting plates 5 to rotate through the first motor 3, the connecting plates 5 can stir the sewage in the liquid storage barrel 1; three hollow shafts 6 are rotatably arranged on the connecting plates 5 at intervals; three rotating plates 7 are connected to the hollow shafts 6 at intervals.

The channel 9 is communicated with the through holes 8 and is also communicated with the inside of the hollow shaft 6; a liquid infusion mechanism is arranged on the support frame 2, and the liquid infusion mechanism is used to input the solution containing microorganisms into the inside of the hollow shaft 6, so that the solution containing microorganisms is discharged into the sewage through the channel 9 and the through holes 8 for mixing, so that the microorganisms can degrade the organic pollutants in the sewage; a cleaning mechanism is arranged inside the liquid storage barrel 1, and the cleaning mechanism is used to clean the inside of the liquid storage barrel 1; a stirring mechanism is also arranged on the support frame 2, and the stirring mechanism is used to pre-stir the solution containing microorganisms. Through stirring, these components of the microorganisms can be evenly distributed in the solution, avoiding the situation of too high or too low local concentration.

[0030] See Figure 6 and Figure 7 As shown in the figure, the liquid infusion mechanism includes a feeding barrel 1001, a sleeve 1002, a connecting pipe 1003, a hollow pipe 1004 and a valve 1005; a feeding barrel 1001 is installed on the upper right side of the support frame 2, and the feeding barrel 1001 is used for feeding the solution containing microorganisms; a sleeve 1002 is rotatably arranged on the upper side of the connecting rod 4, and the inside of the sleeve 1002 is a hollow structure. A connecting pipe 1003 is arranged on the upper side of the support frame 2. The left end of the connecting pipe 1003 is communicated with the sleeve 1002, and the right end of the connecting pipe 1003 is communicated with the feeding barrel 1001; a hollow pipe 1004 is connected to the connecting rod 4, and the top of the hollow pipe 1004 is rotatably communicated with the sleeve 1002 and is also rotatably communicated with the hollow shaft 6. A valve 1005 is arranged on the connecting pipe 1003.

[0031] See Figure 7 As shown in the figure, the cleaning mechanism includes a first spray pipe 1101, a second spray pipe 1102 and an electromagnetic valve 1103; the first spray pipe 1101 is communicated with the connecting pipe 1003 at intervals; the second spray pipe 1102 is communicated with the left side of the sleeve 1002, and electromagnetic valves 1103 are installed on both the first spray pipe 1101 and the second spray pipe 1102.

[0032] See Figure 6 and Figure 8As shown in the figure, the stirring mechanism includes a second motor 1201 and a stirrer 1202; the second motor 1201 is installed on the upper right side of the support frame 2, and the second motor 1201 is located directly below the feeding barrel 1001; a stirrer 1202 is rotatably arranged in the feeding barrel 1001, and the bottom end of the stirrer 1202 is connected to the output shaft of the second motor 1201. The stirrer 1202 is used for pre-stirring the solution containing microorganisms.

[0033] During use, first pour the sewage into the liquid storage barrel 1 so that the sewage submerges the connecting plate 5. Then pour the solution containing microorganisms into the feeding barrel 1001. Then drive the stirrer 1202 to rotate through the second motor 1201, so that the stirrer 1202 pre-stirs the solution containing microorganisms in the feeding barrel 1001, so that these components of the microorganisms are evenly distributed in the solution, avoiding the occurrence of too high or too low local concentration. After the solution containing microorganisms in the feeding barrel 1001 is pre-stirred, then drive the stirrer 1202 to stop rotating through the second motor 1201. Then open the valve 1005 so that the solution containing microorganisms in the feeding barrel 1001 flows into the inner side of the connecting pipe 1003 and the sleeve 1002, so that the solution containing microorganisms enters the inner side of the hollow shaft 6 along the hollow pipe 1004, and then the solution containing microorganisms is discharged into the sewage through the channel 9 and the through hole 8, so that the solution containing microorganisms is mixed with the sewage, and the microorganisms degrade the organic pollutants in the sewage. At the same time, drive the connecting rod 4, the connecting plate 5, the hollow shaft 6 and the rotating plate 7 to rotate through the first motor 3, so that the through holes 8 on the rotating plate 7 evenly discharge the solution containing microorganisms into the sewage, thereby accelerating the diffusion process of the microorganisms, avoiding the problem of too high or too low concentration of microorganisms in a local area. At the same time, use the connecting plate 5 to stir the sewage, which can keep the microorganisms in the sewage in a suspended state, maintain a high biological activity, avoid the microorganisms from settling to the bottom of the liquid storage barrel 1, and can also increase the dissolved oxygen content in the sewage, provide sufficient oxygen for the microorganisms, and promote their metabolic activities and the decomposition of organic matter. During the rotation of the connecting plate 5, affected by the resistance of the sewage in the rotating plate 7, the sewage will squeeze the rotating plate 7 to rotate, so that the through holes 8 on the rotating plate 7 discharge the solution containing microorganisms in different directions through self-rotation, thereby further accelerating the diffusion of the microorganisms. After all the solution containing microorganisms in the feeding barrel 1001 is drained, then close the valve 1005, and then wait for the microorganisms to degrade the organic pollutants in the sewage in the liquid storage barrel 1. After all the organic pollutants in the sewage in the liquid storage barrel 1 are degraded, then drive the connecting rod 4, the connecting plate 5, the hollow shaft 6 and the rotating plate 7 to stop rotating through the first motor 3. As the connecting plate 5 stops rotating, the water resistance received by the rotating plate 7 will gradually decrease until the rotating plate 7 stops rotating, and then drain the sewage in the liquid storage barrel 1 through the drain valve; Afterwards, when it is necessary to clean the inner side of the liquid storage barrel 1, open the valve 1005 and the solenoid valve 1103, and pour clean water into the feeding barrel 1001, so that the clean water flows into the connecting pipe 1003, the sleeve 1002, the hollow pipe 1004 and the hollow shaft 6, and the clean water is discharged into the inner side of the liquid storage barrel 1 through the channel 9 and the through hole 8, so as to wash the inner side of the liquid storage barrel 1, the surface of the connecting rod 4, the connecting plate 5 and the hollow shaft 6. At the same time, when the clean water flows through the connecting pipe 1003 and the sleeve 1002, the clean water will be sprayed out through the first spray pipe 1101 and the second spray pipe 1102, so that the clean water sprayed out by the first spray pipe 1101 washes the upper surface of the connecting rod 4, and the clean water sprayed out by the second spray pipe 1102 washes the surface of the hollow pipe 1004. In this way, the inner side of the liquid storage barrel 1 can be washed clean, and the washed clean water is discharged through the drain valve on the liquid storage barrel 1. After the inner side of the liquid storage barrel 1 is washed clean, close the valve 1005 and the solenoid valve 1103.

[0034] See Figure 9 and Figure 10 As shown, it further includes an oxygen supply mechanism. The oxygen supply mechanism includes a connecting frame 13, a guide rod 14, an arc-shaped movable plate 15, a ventilation pipe 16, an aeration stone 17, an arc-shaped pipe 18, an air delivery member and a lifting member; a connecting frame 13 is installed on the top of the support frame 2; guide rods 14 are symmetrically arranged front and back on the upper side of the connecting frame 13; an arc-shaped movable plate 15 is slidably arranged between the two guide rods 14; ventilation pipes 16 are arranged at intervals on the arc-shaped movable plate 15, and the ventilation pipes 16 are located directly above the liquid storage barrel 1; the bottom end of the ventilation pipe 16 is connected with an aeration stone 17. When the ventilation pipe 16 extends into the sewage and air is discharged from the ventilation pipe 16, the aeration stone 17 can allow air to pass through and form bubbles in the water, thereby increasing the oxygen content in the water; the top ends of the ventilation pipes 16 are communicated with an arc-shaped pipe 18; the air delivery member includes an air pump 19 and an air delivery pipe 20. An air pump 19 is installed on the top of the support frame 2, the air pump 19 is located on the right side of the connecting frame 13, and the air outlet of the air pump 19 is communicated with the arc-shaped pipe 18 through the air delivery pipe 20. The air pump 19 is used to input air into the arc-shaped pipe 18 through the air delivery pipe 20; the lifting member includes a third motor 21 and a lead screw 22. Third motors 21 are symmetrically arranged front and back on the upper side of the connecting frame 13, lead screws 22 are symmetrically arranged front and back and rotatably on the upper side of the connecting frame 13. The two lead screws 22 are located outside the two guide rods 14, and the lead screws 22 are located directly below the third motors 21. The arc-shaped movable plate 15 is threadedly connected with the lead screws 22, and the top end of the lead screw 22 is connected with the output shaft of the third motor 21.

[0035] By setting up an oxygen supply mechanism, when waiting for microorganisms to degrade organic pollutants in the sewage in the liquid storage tank 1, the first motor 3 can be intermittently driven to rotate the connecting rod 4, the connecting plate 5, the hollow shaft 6 and the rotating plate 7. When the connecting rod 4, the connecting plate 5, the hollow shaft 6 and the rotating plate 7 rotate, the sewage is agitated by the connecting plate 5 to ensure the suspended state of microorganisms in the sewage and maintain a high biological activity. When the connecting rod 4, the connecting plate 5, the hollow shaft 6 and the rotating plate 7 stop rotating, the third motor 21 is driven to rotate the lead screw 22, so that the arc-shaped movable plate 15, the air pipe 16 and the aeration stone 17 move downward, so that the air pipe 16 and the aeration stone 17 are immersed in the sewage. Then, the air pump 19 is started to pump air into the arc-shaped pipe 18 and the air pipe 16 through the air delivery pipe 20, and the air is discharged through the aeration stone 17. The aeration stone 17 allows air to pass through and form bubbles in the sewage, thereby increasing the oxygen content in the sewage, providing sufficient oxygen for microorganisms, and promoting their metabolic activities and the decomposition of organic matter. Then, when it is necessary to drive the connecting rod 4, the connecting plate 5, the hollow shaft 6 and the rotating plate 7 to rotate again by the first motor 3, the air pump 19 is first turned off, and then the third motor 21 is driven to reverse and reset the lead screw 22, so that the arc-shaped movable plate 15, the air pipe 16 and the aeration stone 17 move upward and reset, so that the air pipe 16 and the aeration stone 17 leave the sewage. Then, the connecting rod 4, the connecting plate 5, the hollow shaft 6 and the rotating plate 7 can be driven by the first motor 3 to rotate again, and the above operations are repeated. In this way, when the oxygen content in the sewage is appropriate, the sewage can be intermittently stirred to prevent mechanical damage to some microorganisms caused by overly strong stirring, especially relatively fragile strains, which may affect their growth and metabolic functions.

[0036] See Figure 11 As shown, it further includes a scraper 23; a scraper 23 is provided at the top of the liquid storage tank 1, and the air pipe 16 slidably passes through the scraper 23. The scraper 23 is used to scrape off the microorganisms attached to the outer surface of the air pipe 16.

[0037] By setting up the scraper 23, when the air pipe 16 moves upward and resets, the scraper 23 can scrape off the microorganisms attached to the outer surface of the air pipe 16, so that the microorganisms fall back into the sewage again.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention.
