Description

Technical Field

[0001] The utility model relates to the technical field of automatic aeration, in particular to an automatic control aeration device. Background Art

[0002] In the water treatment process, the aeration device is a key device for biological pretreatment of water supply and biological treatment of sewage. Its function is to take certain technical measures to transfer the oxygen in the air into the liquid in the aeration tank through the aeration device, so as to supply the oxygen required for the aerobic biological metabolism, and at the same time fully and evenly mix the water body in the tank to achieve the purpose of biological treatment.

[0003] A Chinese patent with the publication number CN109019848A discloses an aeration device, which includes a box body, a driving motor arranged on the top of the box body, and a movable aeration device arranged at the bottom of the box body. An inlet is arranged on one side of the box body, an outlet is arranged on the other side of the box body, a first valve is arranged on the inlet, a second valve is arranged on the outlet, and a filtering device capable of generating vibration is arranged at the outlet; the purified sewage is discharged from the box body after passing through the filtering effect of the filtering device, so as to avoid the problem that when the water flows out of the box body, the dirt at the bottom of the box body is carried out together, causing secondary pollution to the water flow, and improving the purification effect of the sewage through the setting of the filtering device.

[0004] Currently, in the prior art, when the existing sewage is biologically treated, it takes a long time to wait for the biological substances to biologically treat the inside of the sewage. When the sewage is treated, the impurities inside will settle and accumulate inside the reaction tank, and the clear water separated at the top is collected. Only when the clear water is collected, the internal impurity sewage is discharged and cleaned. Since the clear water is cleaned, the remaining sewage volume inside will be relatively small. When collecting the sewage, without the subsequent injection of clear water, a large part of the sludge will be left inside the sewage tank and cannot be cleaned. If the clear water and sewage are absorbed simultaneously, when the clear water is absorbed, it will drive the sewage to flow, and the sewage cannot be absorbed.

[0005] Therefore, the utility model provides an automatic control aeration device. Summary of the Utility Model

[0006] Therefore, the technical problem to be solved by the utility model is to overcome the problem in the prior art that when the water source of the sewage is extracted after biological treatment, the water source cannot be absorbed simultaneously, and when a certain type of water source is collected alone, it will take too much time and the sewage cannot be absorbed.

[0007] To solve the above technical problem, the utility model provides an automatic control aeration device.

[0008] In one embodiment of the utility model, a conical aeration tank is included, on the inner surface of which an aeration unit is fixedly installed, the aeration unit includes an aerator and a nano bubble spray strip, and on the top outer surface of the conical aeration tank a sewage filtration and discharge unit is movably overlapped, the sewage filtration and discharge unit includes a conical seepage collection shell and a filtration seepage net.

[0009] In one embodiment of the utility model, the outer surface of the aerator is fixedly connected to the inner surface of the conical aeration tank, and the sewage is diverted into the interior of the conical aeration tank through the sewage diversion pipe. At the same time, the aerator cooperates to infuse high-pressure oxygen into the interior of the nanobubble spray strip so that it is discharged in the form of nanobubbles, providing the required oxygen for the metabolism of aerobic organisms in the sewage, and fully and evenly mixing the water in the tank to achieve the effect of biological treatment. At the same time, a sedimentation agent is infused into the interior of the sewage to settle large particles of impurities such as mud and sand in the sewage. A pad support column is fixedly connected to the inner surface of the top of the conical aeration tank.

[0010] In one embodiment of the utility model, the bottom surface of the nano bubble spraying strip is fixedly connected to the top surface of the elevated support column, and the inner surface of the nano bubble spraying strip is fixedly connected to an air guide tube.

[0011] In one embodiment of the utility model, a support frame is movably overlapped on the top surface of the conical aeration tank, and one end of the support frame is fixedly connected to the outer surface of the conical seepage collection shell.

[0012] In one embodiment of the utility model, a water source extraction pipe is fixedly connected to the outer surface of the conical water seepage collection shell, which cooperates with the water source extraction pipe to absorb the clean water inside the conical water seepage collection shell and discharge it. The filter seepage net is located on the bottom inner surface of the conical water seepage collection shell. The clean water separated on the top surface will pass through the filter seepage net to perform secondary filtration on the sewage, and the water source will penetrate into the interior of the conical water seepage collection shell.

[0013] In an embodiment of the present utility model, a padding gap is provided between the bottom surface of the nano-bubble spraying strip and the inner bottom surface of the conical aeration tank. By using the gap between the nano-bubble spraying strip and the inner surface of the conical aeration tank, the sludge is concentrated. After the sewage is initially completely separated, a solid impurity recovery pipe is fixedly connected to the outer surface of the conical aeration tank. While the clear water source is being absorbed, the solid impurity recovery pipe is used to absorb the sludge settled at the inner bottom of the conical aeration tank. With the different lengths of multiple solid impurity recovery pipes extending, the sludge impurities at the middle position and the four peripheral positions inside the conical aeration tank are simultaneously absorbed. When the sludge water is being absorbed, it drives the flow of the sewage. With the subsequent water source provided by the clear water to push, the flow rate of the sewage is greatly increased, and the accumulation of the sludge water is quickly reduced, achieving the simultaneous absorption of sewage and clear water and accelerating the water source discharge rate.

[0014] In an embodiment of the present utility model, one end of the solid impurity recovery pipe extends to the inner surface of the padding gap. A sewage diversion pipe is fixedly installed at the left edge position of the top of the conical aeration tank. When the water source is completely absorbed, the conical water seepage collection shell is removed, and the sewage diversion pipe is used to pour new sewage into the conical aeration tank, reducing the time for each sewage sedimentation and water source replacement and increasing the sewage aeration efficiency.

[0015] For the automatic control aeration equipment of the present utility model, the sewage is diverted into the conical aeration tank through the sewage diversion pipe. At the same time, the nano-bubble spraying strip is filled with high-pressure oxygen through an aerator and discharged in the form of nano-bubbles, providing the required oxygen for the metabolism of aerobic organisms in the sewage and fully and evenly mixing the water body in the tank to achieve the biological treatment effect. At the same time, a sedimentation agent is poured into the sewage to cause large particle impurities such as sediment in the sewage to settle. By using the gap between the nano-bubble spraying strip and the inner surface of the conical aeration tank, the sludge is concentrated. After the sewage is initially completely separated, the conical water seepage collection shell is placed into the conical aeration tank and supported by a support frame on the top surface of the conical aeration tank. The clear water separated on the top surface will pass through the filter seepage net to filter the sewage for the second time, and the water source will seep into the conical water seepage collection shell. The clear water inside the conical water seepage collection shell is absorbed through the water source extraction pipe and discharged.

[0016] The automatic control aeration equipment described in the utility model, when the clean water source is absorbing, cooperates with the solid impurity recovery pipe to absorb the sludge settled at the bottom of the inner side of the conical aeration tank, cooperates with a plurality of solid impurity recovery pipes extending at different lengths, and simultaneously absorbs the sludge impurities in the middle position of the inner side and the surrounding edge positions of the conical aeration tank. The sludge water will drive the flow of sewage when being absorbed, and the subsequent water source is driven by the clean water, which greatly increases the flow speed of the sewage, increases and quickly reduces the accumulation of sludge water, achieves the simultaneous absorption of sewage and clean water, and accelerates the water source discharge speed. When the water source is completely absorbed, the conical seepage collection shell is removed, and the sewage diversion pipe is cooperated to infuse new sewage into the interior of the conical aeration tank, thereby reducing the sewage sedimentation time and water source replacement time each time, and increasing the sewage aeration efficiency.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] Reference Figures 1 to 5As shown in the figure, the automatic control aeration device of the present utility model includes a conical aeration tank 11. An aeration unit is fixedly installed on the inner surface of the conical aeration tank 11. The aeration unit includes an aerator 16 and a nano-bubble spraying strip 17. A sewage filtration and discharge unit is movably lapped on the outer surface of the top of the conical aeration tank 11. The sewage filtration and discharge unit includes a conical water seepage collection shell 13 and a filtration water seepage net 110. The outer surface of the aerator 16 is fixedly connected to the inner surface of the conical aeration tank 11. Sewage is diverted into the interior of the conical aeration tank 11 through a sewage diversion pipe 15. At the same time, the aerator 16 is used to infuse high-pressure oxygen into the interior of the nano-bubble spraying strip 17, so that it is discharged in the form of nano-bubbles, providing the required amount of oxygen for the metabolism of aerobic organisms in the sewage, and at the same time fully and evenly mixing the water body in the tank to achieve the effect of biological treatment. At the same time, a settling agent is infused into the sewage, so that large-particle impurities such as sediment in the sewage settle. A heightening support column 111 is fixedly connected to the inner surface of the top of the conical aeration tank 11. The bottom surface of the nano-bubble spraying strip 17 is fixedly connected to the top surface of the heightening support column 111. An air duct 18 is fixedly connected to the inner surface of the nano-bubble spraying strip 17. A support frame 12 is movably lapped on the top surface of the conical aeration tank 11. One end of the support frame 12 is fixedly connected to the outer surface of the conical water seepage collection shell 13. The conical water seepage collection shell 13 is placed into the interior of the conical aeration tank 11 and is supported by the support frame 12 lapping on the top surface of the conical aeration tank 11 to support its position. A water source extraction pipe 14 is fixedly connected to the outer surface of the conical water seepage collection shell 13. The clear water inside the conical water seepage collection shell 13 is absorbed through the water source extraction pipe 14 and discharged. The position of the filtration water seepage net 110 is arranged on the inner surface of the bottom of the conical water seepage collection shell 13. The clear water separated on the top surface will pass through the filtration water seepage net 110 to filter the sewage again, and the water source will seep into the interior of the conical water seepage collection shell 13.

[0026] Further, as Figures 1 to 5As shown, there is a cushion gap between the bottom surface of the nano-bubble discharge strip 17 and the inner bottom surface of the conical aeration tank 11. The gap between the nano-bubble discharge strip 17 and the inner surface of the conical aeration tank 11 is used to concentrate the sludge. After the sewage is initially completely separated, a solid impurity recovery pipe 19 is fixedly connected to the outer surface of the conical aeration tank 11. While the clean water source is being absorbed, the solid impurity recovery pipe 19 is used to absorb the sludge settled at the inner bottom of the conical aeration tank 11. With the different lengths of multiple solid impurity recovery pipes 19 extending, the sludge impurities at the middle position and the four peripheral positions inside the conical aeration tank 11 are simultaneously absorbed. When the sludge water is being absorbed, it will drive the flow of the sewage. With the subsequent water source provided by the clean water to push, the flow rate of the sewage is greatly increased, and the accumulation of the sludge water is quickly reduced, achieving the simultaneous absorption of sewage and clean water, accelerating the water discharge speed. One end of the solid impurity recovery pipe 19 extends to the inner surface of the cushion gap. A sewage diversion pipe 15 is fixedly installed at the top left edge position of the conical aeration tank 11. After the water source is completely absorbed, the conical water-permeable collection shell 13 is removed, and new sewage is poured into the conical aeration tank 11 through the sewage diversion pipe 15, reducing the sewage sedimentation and water replacement time each time and increasing the sewage aeration efficiency.

[0027] Working principle: The sewage is diverted into the conical aeration tank 11 through the sewage diversion pipe 15. At the same time, the high-pressure oxygen is injected into the nano-bubble discharge strip 17 by the aerator 16, and it is discharged in the form of nano-bubbles, providing the required oxygen for the metabolism of aerobic organisms in the sewage. At the same time, the water body in the tank is fully and evenly mixed to achieve the biological treatment effect. At the same time, a sedimentation agent is injected into the sewage to make the large particle impurities such as sediment in the sewage settle, resulting in the separation state of sludge and water in the sewage. The gap between the nano-bubble discharge strip 17 and the inner surface of the conical aeration tank 11 is used to concentrate the sludge. After the sewage is initially completely separated, the conical water-permeable collection shell 13 is placed into the conical aeration tank 11, and it is supported on the top surface of the conical aeration tank 11 by the support frame 12. The clean water separated on the top surface will filter the sewage again through the filter water-permeable net 110, and the water source will penetrate into the conical water-permeable collection shell 13. The clean water inside the conical water-permeable collection shell 13 is absorbed through the water source extraction pipe 14 and discharged.

[0028] While Qingshuiyuan is performing absorption, it cooperates with the solid impurity recovery pipe 19 to absorb the sludge sedimented at the inner bottom of the conical aeration tank 11. Since the lengths of the multiple solid impurity recovery pipes 19 are different, the sludge impurities at the middle position and the four peripheral positions inside the conical aeration tank 11 can be absorbed simultaneously. When the sludge water is being absorbed, it will drive the flow of the sewage. With the subsequent water source provided by the clear water to push, the flow rate of the sewage is greatly increased, and the accumulation of the sludge water is quickly reduced. Thus, the sewage and the clear water are absorbed simultaneously, and the water source discharge speed is accelerated. When the water source is completely absorbed, the conical water seepage collection shell 13 is removed, and new sewage is poured into the inside of the conical aeration tank 11 through the sewage diversion pipe 15, reducing the time for each sewage sedimentation and water source replacement and increasing the sewage aeration efficiency.

[0029] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
