Description

Technical Field

[0001] The invention relates to the technical field of filtered water treatment, and in particular to an aerated filtered water treatment device. Background Art

[0002] In daily life, people's various activities will produce wastewater containing organic matter, such as food residues and grease in kitchen wastewater, surfactants in laundry wastewater, and urea and feces in toilet wastewater. At the same time, many industrial production processes will also produce a large amount of wastewater rich in organic matter, such as wastewater containing lignin and cellulose in the papermaking industry, wastewater containing benzene, phenol, alcohol, etc. in the chemical industry, and wastewater containing dyes and auxiliaries in the printing and dyeing industry.

[0003] Common filtration methods such as sand filtration and carbon filtration mainly rely on physical interception and adsorption, and it is difficult to completely remove organic matter in the water, so the filtered water may still contain organic matter. The aeration filtration water treatment device combines aeration and filtration functions, and can be used to remove suspended matter, organic matter, ammonia nitrogen and other pollutants in the water. It increases the oxygen supply by adjusting the air content, provides sufficient oxidants for the oxidation reaction, and allows organic matter to be quickly decomposed into harmless substances such as carbon dioxide and water under the action of microorganisms, thereby achieving sewage purification. For example, an aeration filtration water treatment device and method disclosed in Publication No. CN115093018A can aerate the filtered water.

[0004] In actual sewage pool treatment, it is necessary to adjust the oxygen content in the aeration device according to the real-time situation of the sewage pool. When the concentration of organic matter in the sewage suddenly increases, such as when a large amount of industrial wastewater is received or when domestic sewage is discharged at a peak, the oxygen demand of microorganisms to decompose organic matter increases, and the oxygen content needs to be increased at this time. In addition, when the temperature is low, although the dissolved oxygen saturation in the water increases, the activity of microorganisms decreases. In order to increase their activity, the air content also needs to be appropriately increased. However, in daily life, the aeration treatment time is relatively long to allow the microorganisms to fully decompose and metabolize. The detection in the existing technology cannot monitor the situation in the sewage pool in real time, and when a large amount of sewage enters the sewage pool, the environment in the sewage pool will become complicated, and the detection device therein cannot be adjusted accordingly.

At the same time, by extracting sewage from the pipeline for monitoring, the monitoring effect is effectively guaranteed. The sewage entering the sealing sleeve drives the sealing leaf to rotate, and then drives the protective collar and protective frame to rotate.

When one of the filters is blocked, it will be reversely flushed with clean water, so that the entire aeration device can be used continuously and uninterruptedly. The sealing pipes and the pipes staggered in the aeration pipes will prevent the sewage in the sewage aeration tank from flowing into the pipes when the aeration device is in the stop state, further ensuring that the device will not be blocked.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0032] The present invention will be further described below in conjunction with the embodiments.

[0033] Example: Refer to Figures 1 to 9 An aeration and filtration water treatment device includes a sewage aeration tank 1, an air compressor 2 fixed on the sewage aeration tank 1, a cross connecting pipe 6 fixed in the sewage aeration tank 1, the air compressor 2 and the cross connecting pipe 6 are connected by a pipeline, a floating monitoring mechanism 3 arranged in the sewage aeration tank 1, including an aeration mechanism 4 fixed on the cross connecting pipe 6, and also including a filtering mechanism 5 fixed in the sewage aeration tank 1.

[0034] It should be noted that the device extracts sewage from the sewage aeration tank 1 through the filtering mechanism 5. In the process of extracting sewage, the colloidal substances therein are filtered to prevent the device from being blocked. Then, compressed air is added to the pipeline through the air compressor 2. Finally, the aeration mechanism 4 is used to spray in the sewage aeration tank 1, so that the device can achieve the aeration effect. The floating monitoring mechanism 3 therein can monitor the sewage content and temperature in the sewage aeration tank 1, so as to increase the oxygen content in the sewage during aeration in real time. Since there are many colloidal substances in the sewage in the sewage aeration tank 1, the two filtering components are used alternately, and the blocked filtering component is backwashed, so that the device can always be started;

[0035] When the concentration of organic matter in sewage increases suddenly, such as when a large amount of industrial wastewater or domestic sewage is discharged at a peak, the workload of microorganisms to decompose organic matter increases, and the oxygen demand also increases accordingly. In the case of low temperature, the dissolved oxygen saturation in the water will increase, but the activity of the microorganisms will decrease. In order to improve the activity of microorganisms, it is necessary to appropriately increase the air content to promote the metabolic reaction of microorganisms and maintain a better treatment effect. That is to say, when a large amount of sewage is suddenly added to the sewage aeration tank 1 and the sewage temperature drops rapidly due to weather reasons, the float monitoring mechanism 3 will control the air compressor 2 to add more oxygen into the pipeline to maintain the treatment efficiency of the microorganisms in the sewage aeration tank 1.

[0036] Further explanation, in order to monitor the sewage in the sewage aeration tank 1 in real time, the following settings are made, such as Figure 3 As shown, the float monitoring mechanism 3 includes a sealed shell 31, a micro water pump 32 is fixed to the bottom wall of the sealed shell 31, and an input end of the micro water pump 32 is connected to an L-shaped tube 30. The micro water pump 32 will slowly draw the sewage in the sewage aeration tank 1 into the L-shaped tube 30. A thermistor is fixed in the L-shaped tube 30. The thermistor is arranged in the L-shaped tube 30, which can not only ensure that the thermistor will not be affected by the ambient temperature, but also prevent the sewage flow rate from reducing the accuracy of the thermistor. A rectangular groove is opened in the middle of the upper end of the sealed shell 31, and a pressure sensor 33 is fixed in the rectangular groove. Since the float monitoring mechanism 3 is located in the sewage aeration tank 1, when a large amount of sewage is admitted in the sewage aeration tank 1, the water pressure therein will be enhanced, which can be accurately sensed by the pressure sensor 33;

[0037] Then, a PLC controller 34 is also fixed to the bottom wall of the sealed housing 31. The micro water pump 32, the pressure sensor 33 and the PLC controller 34 are connected by electrical signals to form a monitoring loop. The PLC controller 34 is connected to the air compressor 2 by electrical signals to form a processing loop. The thermistor is connected to the PLC controller 34 by electrical signals. The pressure sensor 33 is a piezoelectric type. When the pressure sensor 33 is subjected to a greater water pressure, the current therein will increase. The thermistor is a negative temperature series. When the sewage temperature decreases, the resistance of the thermistor will decrease, so that the current will also increase. When the current increases, an electrical signal will be transmitted to the air compressor 2 through the PLC controller 34, so that the air compressor 2 will add more oxygen into the device.

[0038] Then, a protective cover 35 is fixed to the lower end of the sealed shell 31, a driving assembly 36 is fixed to the middle part of the lower end of the sewage aeration tank 1, and the output end of the micro pump 32 is connected to the driving assembly 36 through a pipeline, and the sewage extracted by the micro pump 32 will enter the driving assembly 36. The outer surface of the protective cover 35 is attached with a protective collar 37, and the outer surface array of the protective collar 37 is provided with a plurality of rectangular holes 38. A protective frame 39 is fixed to the upper end of the protective collar 37. In order to ensure that the thermistor and the pressure sensor 33 can always be used normally, when the sewage extracted by the micro pump 32 enters the driving assembly 36, the components in the driving assembly 36 can drive the protective collar 37 and the protective frame 39 to rotate. The purpose of the rotation of the protective collar 37 is to prevent large pieces of colloidal substances from entering the pipeline so that impurities will not affect the thermistor, and the purpose of the rotation of the protective frame 39 is to clean the colloidal substances on the sealed shell 31 so that the weight of the impurities will not affect the pressure sensor 33.

[0039] It should be noted that when a large amount of sewage enters the sewage aeration tank 1, the sewage liquid level will rise, and the pressure sensor 33 will maintain a constant height along with the sealing shell 31. That is to say, the more sewage enters the sewage aeration tank 1, the higher the liquid level, and the greater the water pressure on the pressure sensor 33. By monitoring the water pressure of the sewage in the sewage aeration tank 1, real-time monitoring of the sewage status in the sewage aeration tank 1 can be achieved.

[0040] To further illustrate, in order to drive the components in the float monitoring mechanism 3 to rotate, the following settings are performed, such as Figure 4As shown, the driving assembly 36 includes a sealing sleeve 361, a water inlet hole 362 is opened on the outer surface of the sealing sleeve 361, and a water outlet hole 363 is opened on the other side of the outer surface of the sealing sleeve 361. The diameter of the water inlet hole 362 is smaller than the diameter of the water outlet hole 363, so that the sewage entering the sealing sleeve 361 has a larger driving force. A connecting shaft 364 is rotatably connected inside the sealing sleeve 361, and a sealing leaf 365 is fixed on the outer surface of the connecting shaft 364. The outer surface of the sealing leaf 365 is airtightly attached to the inner wall of the sealing sleeve 361. The sewage will not flow through the gap between the sealing leaf 365 and the inner wall of the sealing sleeve 361, but will push the sealing leaf 365 to rotate, so that the sealing leaf 365 can drive the protective collar 37 to rotate through the connecting shaft 364. The lower end of the connecting shaft 364 passes through the outside of the sealing sleeve 361, and the lower end of the connecting shaft 364 is fixedly connected to the protective collar 37.

[0041] It should be noted that the water entering the aeration tank will undergo multi-stage treatment, that is, most of the impurities have been removed from the water entering the aeration tank, but it may still contain some fine suspended particles and colloidal substances, the particles of which will cause the device to be blocked, and the colloidal substances in which will affect the monitoring function of the pressure sensor 33. Since a large amount of sewage enters the sewage aeration tank 1, more colloidal substances will be added to the sewage aeration tank 1. The substances will float upward under the action of buoyancy, and they will not float vertically upward during the floating process. When the colloidal substances in them become more, some substances with gravity will float to the vicinity of the pressure sensor 33. When the colloidal impurities are connected, they will fall onto the pressure sensor 33 under the action of their own gravity, affecting the detection effect of the pressure sensor 33. In order to prevent the substances from affecting the normal use of the pressure sensor 33, when the pressure sensor 33 is subjected to greater pressure, the working efficiency of the micro water pump 32 will be increased, so that the micro water pump 32 can draw more sewage into the drive assembly 36, increase the rotation speed of the protective collar 37 and the protective frame 39, and reduce the impact of the substances on the device.

[0042] Further explanation, in order to better perform aeration work in the sewage aeration tank 1, the following settings are made, such as Figure 5 and Figure 6As shown, the aeration mechanism 4 includes an aeration pipe 41 connected to the cross connecting pipe 6. The sewage in the cross connecting pipe 6 has been mixed with compressed air. A plurality of blocks 42 are symmetrically fixed in the aeration pipe 41. The blocks 42 separate the aeration pipe 41 into four sealed cavities. The horizontal end faces of the blocks 42 are all fixed with elastic members 43. The other ends of the elastic members 43 are all fixed with sealing pipes 44. The four lower ports of the cross connecting pipe 6 are all located between the two sealing pipes 44. The outer surfaces of the sealing pipes 44 are all provided with air holes. 45. The outer surface of the aeration pipe 41 is provided with a plurality of air holes 46 matched with the air holes 45. An aeration head 47 is fixed in each of the air holes 46. Only when sewage enters the aeration pipe 41 can the two sealed pipes 44 located in the same sealed cavity be pushed to move away from each other, so that the air holes 45 and the air holes 46 overlap, and then are sprayed into the sewage aeration tank 1 through the aeration head 47, thereby increasing the oxygen content in the sewage aeration tank 1 and enabling the microorganisms therein to decompose and metabolize better.

[0043] To further explain, in order to filter the sewage entering the aeration device, the following settings are made, such as Figure 7 and Figure 8 As shown, the filtering mechanism 5 includes a water pump 51 fixed on the sewage aeration tank 1, an adjusting component 52 is fixed on the output end of the water pump 51, and one end of the adjusting component 52 away from the water pump 51 is connected to two filters 53, and a clean water tank 54 is provided on the upper side of the water pump 51. The clean water tank 54 is connected to the other ends of the two filters 53 by two pipes, and a liquid pumping device is provided in the clean water tank 54. By controlling the opening and closing of the valve, the pumping device pumps clean water into the filter 53 that has been blocked by impurities, so as to realize reverse flushing to achieve the purpose of cleaning;

[0044] A rectangular shell 56 is provided on the upper side of the filter 53. The rectangular shell 56 is connected to the cross connecting pipe 6 by a pipeline, and a one-way valve is provided at the connection between the rectangular shell 56 and the air compressor 2. Two connecting rings 57 are fixed to the end of the rectangular shell 56 away from the adjusting component 52. The rectangular shell 56 is connected to the two filters 53 by the connecting rings 57. Two telescopic rods 58 are symmetrically fixed in the rectangular shell 56. Sealing blocks 59 are fixed to the ends of the two telescopic rods 58 close to each other. The position of the sealing block 59 is adjusted according to the use of the filter 53. When the filter 53 on one side is in working state, the telescopic rod 58 on the same side is in an extended state, while the telescopic rod 58 on the other side is in a shortened state, so that only the filter 53 on one side can be connected to the cross connecting pipe 6.

[0045] Further explanation: In order to allow the two filters 53 to be used alternately, the following settings are made: Fig. 9As shown, the adjustment component 52 includes an adjustment shell 521, a rectangular block 522 is fixed in the middle of the inner cavity of the adjustment shell 521, a movable shell 523 is slidably connected to the inner wall of the adjustment shell 521, and the movable shell 523 is connected to the output end of the water pump 51. A telescopic rod 2 524 is symmetrically fixed in the adjustment shell 521, and the state of the telescopic rod 2 524 is opposite to that of the telescopic rod 1 58 located on the same side, wherein the telescopic rod 1 58 and the telescopic rod 2 524 are connected by a group of hydraulic pumping devices. When the filter 53 on one side is in the working state, the telescopic rod 1 58 on the same side is in the shortened state, and the telescopic rod 1 58 on the other side is in the extended state, so that only one side of the filter 53 can be connected with the adjustment shell 521, so that the sewage entering the adjustment shell 521 can only enter one filter 53;

[0046] Then, the output ends of the second telescopic rod 524 are connected to the movable shell 523. The movable shell 523 is symmetrically provided with wedge-shaped holes 525 on the inner wall near the rectangular block 522. Isolation plates 526 are symmetrically fixed at both ends of the movable shell 523. The two ends of the isolation plate 526 are symmetrically rotatably connected with connecting leaves 527. When the device is in working state, the port of the filter 53 is located between the rectangular block 522 and the isolation plate 526. When the device is in cleaning state, the port of the filter 53 is located between the isolation plate 526 and the inner wall of the adjustment shell 521.

[0047] The working principle of the present invention is as follows: the water pump 51 in the start-up device extracts the sewage in the sewage aeration tank 1 into the regulating shell 521. At this time, one of the telescopic rods 524 is in an extended state, and the other telescopic rod 524 is in a shortened state. The wedge-shaped hole 525 on the same side of the telescopic rod 524 in the extended state will be connected to the sealed cavity, and the sewage entering the movable shell 523 will flow into the filter 53 on the same side through the sealed cavity. The sewage filtered by the filter 53 will enter the rectangular shell 56 and then merge with the compressed air injected into the device by the air compressor 2. After a period of use, the filter 53 will be blocked by the colloidal substance, and the states of the telescopic rod 1 58 and the telescopic rod 2 524 will be reversed (connected by the pumping device). The pumping device uses two pipes to connect the telescopic rod 1 58 and the telescopic rod 2 524 on the same side. When the telescopic rod 1 58 is extended, the telescopic rod 2 524 will be shortened, thereby achieving the purpose of state reversal). The sewage entering the movable housing 523 will flow into the filter 53 on the other side. The pumping device located in the clean water tank 54 will add clean water to the blocked filter 53 through the pipe. After the clean water flows through the filter 53 and is completely cleaned, it flows into the regulating housing 521. Under the blocking of the isolation plate 526 and the connecting leaf 527, the clean water with impurities will not completely fill the regulating housing 521, but will be discharged from the regulating housing 521 into the sewage aeration tank 1. The pumping device will automatically close after it is turned on and the cleaning is completed.

[0048] The sewage mixed with oxygen in the cross connecting pipe 6 will enter the four sealed chambers of the aeration pipe 41. When the sewage enters the aeration pipe 41, it can push the two sealed pipes 44 located in the same sealed chamber to move away from each other, so that the air hole 1 45 and the air hole 2 46 overlap, and then spray it into the sewage aeration tank 1 through the aeration head 47, so as to increase the oxygen content in the sewage aeration tank 1, so that the microorganisms therein can decompose and metabolize better. When the aeration device stops, the sealed pipes 44 will be pushed by the elastic member 43 to move in the direction of approaching each other, so that the sewage in the sewage aeration tank 1 will not enter the aeration pipe 41, and will not cause blockage to the aeration head 47.

[0049] When the device is in the startup state, when the pressure sensor 33 is subjected to a greater water pressure, the current therein will increase. When the sewage temperature decreases, the resistance of the thermistor will decrease, causing the current to increase. When the current increases, an electrical signal will be transmitted to the air compressor 2 through the PLC controller 34, increasing the power of the air compressor 2, so that the air compressor 2 can add more oxygen into the device, ensuring that the microorganisms in the sewage aeration tank 1 can be decomposed and metabolized better. The sewage extracted by the micro pump 32 will enter the driving component 36, and the outer surface of the sealing leaf 365 will be airtightly attached to the inner wall of the sealing sleeve 361. The sewage will not flow through the gap between the sealing leaf 365 and the inner wall of the sealing sleeve 361, but will push the sealing leaf 365 to rotate, so that the sealing leaf 365 can drive the protective collar 37 to rotate through the connecting shaft 364;

[0050] The protective collar 37 will drive the protective frame 39 to rotate at the same time. The purpose of the rotation of the protective collar 37 is to prevent large pieces of colloidal substances from entering the pipeline so that impurities will not affect the thermistor, and the purpose of the rotation of the protective frame 39 is to clean the colloidal substances on the sealing shell 31 so that the weight of the impurities will not affect the pressure sensor 33. It should be noted that when the pressure sensor 33 is subjected to a greater pressure, the working efficiency of the micro water pump 32 will increase, so that the micro water pump 32 will draw more sewage into the driving assembly 36, and the rotation speed of the protective collar 37 and the protective frame 39 will increase, so as to prevent a large amount of sewage from entering the sewage aeration tank 1 and causing blockage.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
