Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to an automatically controlled aerator. Background Technology

[0002] In the field of wastewater treatment, aerators are core equipment. By introducing oxygen into wastewater, they provide a suitable living environment for microorganisms, thereby promoting the decomposition and purification of organic matter in the wastewater.

[0003] The aeration discs of existing aerators are difficult to maintain. They are constantly exposed to wastewater, making them prone to accumulating impurities and corrosion, which affects the aeration effect. The traditional installation and disassembly of aeration discs are complicated, requiring specialized tools and personnel, which consumes a lot of time and effort. This not only increases maintenance costs but also causes long downtime, reducing the continuity and efficiency of wastewater treatment. Therefore, we propose an automatically controlled aerator to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide an automatically controlled aerator to solve the problems mentioned in the background art.

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

[0006] An automatically controlled aerator includes: a float, a dissolved oxygen sensor and a pH sensor installed at the bottom of the float, two sets of brackets fixedly installed at the top of the float, an air pump fixedly installed between the two sets of brackets, an air collection hood connected to the air inlet of the air pump, a hollow tube connected to the air outlet of the air pump, a drive motor installed inside the top of the float, a small gear fixedly installed on the output end of the drive motor, a transmission sleeve rotatably installed inside the float, a large gear fixedly installed on the outer side of the transmission sleeve, and a mounting base fixedly installed at the bottom of the transmission sleeve, the outer side of the mounting base sliding. A connecting seat is installed, and an aeration disc is installed inside the connecting seat. The hollow tube is installed inside the mounting seat. Two sets of guide rods are provided inside the mounting seat. A movable plate is slidably installed on the outer side of each set of guide rods. A locking block is fixedly installed on one side of each set of movable plates. The locking blocks are slidably installed inside the mounting seat and movably inserted into the outer side of the connecting seat. A return spring is sleeved on the outer side of each set of guide rods. An inclined plate is fixedly installed on the top of each set of movable plates. Two sets of limiting rods are fixedly installed on the top of the mounting seat. The same linkage plate is slidably installed on the outer side of the two sets of inclined plates and the two sets of limiting rods.

[0007] Preferably, the air inlet of the gas collecting hood is provided with a filter plate, and two sets of limiting plates are slidably installed inside the gas collecting hood. Each of the two sets of limiting plates has a plug fixedly installed on one side. The two sets of plugs are movably inserted into the outside of the filter plate and slidably installed inside the gas collecting hood. Each of the two sets of limiting plates has a pull rod fixedly installed on the other side. The two sets of pull rods are slidably installed inside the gas collecting hood. Each of the two sets of pull rods has a handle fixedly installed at one end, and a tension spring is sleeved on the outside of each of the two sets of pull rods.

[0008] Preferably, the hollow tube is disposed inside the float and rotatably mounted in the mounting base, the hollow tube is connected to the aeration disc, the large gear and the small gear mesh with each other, and the transmission sleeve is rotatably mounted on the outside of the hollow tube.

[0009] Preferably, the mounting base has two sets of movable slots inside, the two sets of movable plates are slidably installed in the corresponding movable slots, the two sets of guide rods are arranged on both sides of the corresponding movable slots, and the two ends of the two sets of return springs are respectively fixedly installed on one side of the corresponding movable plate and one side of the corresponding movable slot.

[0010] Preferably, the outer side of the connecting seat has two sets of locking grooves, and the two sets of locking blocks are movably inserted into the corresponding locking grooves.

[0011] Preferably, the inside of the gas collection hood is provided with two sets of limiting grooves, the two sets of limiting plates are slidably installed in the corresponding limiting grooves, the two ends of the two sets of tension springs are respectively fixedly installed on one side of the corresponding limiting plate and one side of the corresponding limiting groove, and the outside of the filter plate is provided with two sets of slots, the two sets of inserts are movably inserted into the corresponding slots.

[0012] In this utility model, an automatically controlled aerator is provided. By setting a handle to drive its pull rod and limiting plate to move relative to each other in corresponding limiting grooves, the tension spring contracts and the insert block disengages from the filter plate, thereby enabling quick disassembly of the filter plate. During installation, simply align the slot with the insert block and release the handle. Under the elastic force of the tension spring, the filter plate can be quickly installed without external force, which greatly improves equipment maintenance efficiency, reduces equipment downtime caused by maintenance, and ensures continuous and stable operation of the aerator.

[0013] In this invention, an automatically controlled aerator is provided. By setting up a float, the aerator can float stably on the surface of sewage using its own buoyancy, ensuring that the aeration device is in a suitable working position. By setting up dissolved oxygen sensors and pH sensors, the dissolved oxygen content and pH value in the sewage are monitored in real time, the preset value range is monitored in real time, and the drive motor and air pump are controlled to adjust the aeration value. This avoids the aeration device from malfunctioning or being damaged due to water level fluctuations, and provides a basic guarantee for the continuous and stable operation of the aerator.

[0014] This utility model features a reasonable structural design. Through the interaction of a drive motor, a small gear, and a large gear, the large gear drives the transmission sleeve to rotate within the float, which in turn drives the connected mounting base, connecting base, locking blocks, and aeration disc to rotate. An air pump draws filtered air from the filter plate into the hollow tube and then into the aeration disc, which in turn fills the wastewater with air, achieving the aeration function. Furthermore, a linkage plate moves upward under the constraint of a limit rod, causing two sets of inclined plates and two sets of moving plates to move relative to each other under the constraint of a guide rod and a moving groove. When the return spring contracts, the two sets of locking blocks disengage from the locking groove. The connecting seat and aeration disc can then be quickly disassembled and replaced. During replacement, the connecting seat is placed outside the mounting base, the locking groove is aligned with the locking block, the linkage plate is released, and under the elastic force of the return spring, all components reset. The locking block is then inserted into the locking groove to lock, thus enabling rapid installation of the aeration disc. This quick-replacement of the aeration disc ensures the aerator is always in good working condition, preventing the wastewater treatment effect from being affected by a decline in aeration disc performance. It also prevents the aeration disc from loosening or falling off due to vibration, water flow impact, or other factors, ensuring the stability and safety of the aerator's operation. This greatly improves the automation and intelligence level of wastewater treatment, allowing the equipment to quickly respond to changes in wastewater parameters and maintain efficient operation.

[0022] In this embodiment, the air inlet of the gas collection hood 6 is provided with a filter plate 7. Two sets of limiting plates 23 are slidably installed inside the gas collection hood 6. Insert blocks 24 are fixedly installed on one side of each of the two sets of limiting plates 23. The two sets of insert blocks 24 are movably inserted into the outside of the filter plate 7 and slidably installed inside the gas collection hood 6. Pull rods 25 are fixedly installed on the other side of each of the two sets of limiting plates 23. The two sets of pull rods 25 are slidably installed inside the gas collection hood 6.

[0023] In this embodiment, the hollow tube 22 is disposed inside the float 1 and rotatably mounted in the mounting base 12. The hollow tube 22 is connected to the aeration disc 18. The large gear 10 and the small gear 9 mesh with each other.

[0027] In this embodiment, during use, by setting up a float 1, the aerator can be stably floated on the surface of sewage by its own buoyancy, ensuring that the aeration device is in a suitable working position. By setting up a dissolved oxygen sensor 2 and a pH sensor 3, the dissolved oxygen content and pH value in the sewage are monitored in real time, the preset value range is monitored in real time, and the drive motor 8 and air pump 5 are controlled to adjust the aeration value.
