Description

Technical Field

[0001] This utility model relates to the field of aerator technology, and in particular to a high-efficiency oxygenation aerator device. Background Technology

[0002] An aeration device is a device that supplies oxygen to the aeration tank during the activated sludge process of wastewater treatment. Aeration refers to the artificial introduction of air into a biological aeration tank through appropriate equipment to achieve the desired purpose. Aeration not only brings oxygen into the tank by contacting the liquid with air, but also accelerates the transfer of oxygen from the air to the liquid due to liquid agitation, thus achieving the purpose of oxygenation. In addition, aeration also prevents suspended solids from settling and enhances the contact between organic matter and microorganisms and dissolved oxygen, thereby ensuring that microorganisms in the tank can oxidize and decompose organic matter in wastewater under conditions of sufficient dissolved oxygen. The quality of the aeration device not only affects the biological treatment effect of wastewater, but also directly affects the land area, investment, and operating costs of the treatment plant.

[0003] When in use, existing devices are difficult to adjust the position and height of the aeration device. Since the aeration device is located inside the water body for a long time, debris in the sewage will block the pipes, requiring staff to clean them regularly, which makes the work efficiency low. Therefore, we have proposed a high-efficiency oxygenation aeration device. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient oxygenation aerator device, which solves the existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency oxygenation aerator device includes a mounting plate, a support frame fixedly mounted on the top of the mounting plate, a motor fixedly mounted on the top of the support frame, a lead screw fixedly mounted on the output end of the motor, a lifting plate threaded onto the outer side of the lead screw, a replaceable aeration pipe provided on the inner side of the lifting plate, and a blower fixedly mounted on the top of the mounting plate.

[0007] As a further improvement to the above solution, a gas transmission pipe is fixedly installed at the output end of the blower, and a connecting flange is fixedly installed on the outside of the gas transmission pipe and the replaceable aeration pipe.

[0008] As a further improvement to the above solution, the replaceable aeration pipe has multiple ventilation holes on its outer side, a mounting bracket is fixedly installed on the inner side of the replaceable aeration pipe, and a sealing box is fixedly installed on the inner side of the mounting bracket.

[0009] By adopting the above technical solution, the sealing box can seal and protect the inner drive components, preventing water from entering and damaging the drive motor.

[0010] As a further improvement to the above solution, a driving component is fixedly installed on the inner side of the sealed box, a driving shaft is fixedly installed on the output end of the driving component, and a fan blade is fixedly installed on the outer side of the driving shaft.

[0011] By adopting the above technical solution, during the aeration process, the drive shaft and fan blades can be driven to rotate at high speed by the drive component. The rotation of the fan blades propels the water, preventing anaerobic conditions caused by the sedimentation of activated sludge in the water. The high-speed rotating spiral impeller creates a strong propulsion effect on the water, causing water carrying oxygen molecules and microbubbles to be sprayed and diffused towards the bottom of the tank, thereby driving the sludge to rise. At this time, the slowly rising bubbles are gradually dissolved by the water during the ascent, and the residence time of the microbubbles in the water is greatly extended, allowing the oxygen to be further absorbed by the water, forming secondary dissolved oxygen. Through secondary dissolved oxygen, the oxygen content in the wastewater is greatly increased, thereby improving the ability of microorganisms to treat wastewater.

[0012] As a further improvement to the above solution, a storage battery is fixedly installed on the top of the lifting plate, a power supply cable is fixedly installed on the inner side of the drive component, and a power supply connector is fixedly installed on the outer side of one end of the power supply cable.

[0013] As a further improvement to the above solution, a power supply slot is provided on one side of the battery, and the power supply connector is fitted into the power supply slot.

[0014] As a further improvement to the above solution, threaded holes are provided at the top four corners of the lifting plate and the top four corners of the connecting flange. The connecting flange is connected to the lifting plate by bolts. A guide groove is provided on the front side of the support frame, and the lifting plate is slidably installed inside the guide groove.

[0015] By adopting the above technical solution, the threaded hole allows the bolt to install the connecting flange on the top of the lifting plate, and the connecting flange allows the gas transmission pipe and the replaceable aeration pipe to be connected and fixed above the lifting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (1) The present invention provides a high-efficiency oxygenation aerator device. During the aeration process, the drive shaft and fan blades can be driven to rotate at high speed by the drive component. The fan blades rotate and push the water to flow, which avoids the anaerobic situation caused by the sedimentation of activated sludge in the water. The high-speed rotating spiral impeller forms a strong push on the water, which causes water carrying oxygen molecules and micro bubbles to be sprayed and diffused to the bottom of the pool, thereby driving the sludge to rise. At this time, the slowly rising bubbles are gradually dissolved by the water during the rising process. The residence time of the micro bubbles in the water is greatly extended, which allows the oxygen to be further absorbed by the water and forms secondary dissolved oxygen. Through two dissolutions, the oxygen content in the sewage is greatly increased, thereby improving the ability of microorganisms to treat sewage.

[0018] (2) The present invention provides a high-efficiency oxygenation aerator device, which connects the replaceable aeration pipe and the gas transmission pipe through a connecting flange, so that the airflow generated by the blower can be transmitted to the replaceable aeration pipe through the gas transmission pipe. A drive component is provided inside the sealed box, and the power supply connector above the power supply cable can be inserted into the battery, so that the battery can supply power to the drive component. When aeration is needed, the motor can be controlled to drive the screw to rotate. The screw can be driven to move up and down through the threaded engagement of the lifting plate, thereby adjusting the height of the replaceable aeration pipe in the sewage and increasing the aeration range of the device.

The lifting plate 5 is slidably installed on the inner side of the guide groove.

[0033] The implementation principle of a high-efficiency oxygenation aerator device in this embodiment is as follows: Before aeration of sewage is required, the replaceable aeration pipe 6 can be connected to the gas transmission pipe 8 via a connecting flange 9, allowing the airflow generated by the blower 7 to be transmitted to the replaceable aeration pipe 6 through the gas transmission pipe 8. A drive component is provided inside the sealed box 12, and the power connector 17 above the power cable 16 can be inserted into the battery 15, allowing the battery 15 to supply power to the drive component.

The rotating fan blades 14 propel the water, preventing anaerobic conditions caused by the sedimentation of activated sludge in the water. The high-speed rotating spiral impeller creates a powerful propulsion effect on the water, causing oxygen-carrying water and microbubbles to be sprayed and diffused towards the bottom of the tank, thereby driving the sludge to rise. As the bubbles rise slowly, they are gradually dissolved by the water, greatly extending the residence time of the microbubbles in the water, allowing for further oxygen absorption and forming secondary dissolved oxygen. Through this secondary oxygenation, the oxygen content in the wastewater is greatly increased, thereby enhancing the ability of microorganisms to treat wastewater.
