Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment auxiliary devices, and in particular to a precision aeration control system. Background Technology

[0002] As is well known, precision aeration control systems play a crucial role in many industrial and agricultural fields, such as wastewater treatment, bio-fermentation, and aquaculture. Their core objective is to ensure thorough mixing of gas and liquid in the reaction tank, providing a suitable environment for the growth and metabolism of microorganisms, thereby efficiently achieving processes such as pollutant degradation and material transformation.

[0003] In existing aeration devices, the mixing mechanism is usually responsible for uniformly mixing the activated sludge and treatment agents in the wastewater to prevent sludge sedimentation; the aeration mechanism provides the necessary dissolved oxygen for microorganisms by injecting air or oxygen into the wastewater, promoting their decomposition of pollutants. However, in practice, it has been found that most of these devices exist as independent units. When the system needs maintenance, upgrades, or component replacements due to malfunctions, operators need to disassemble them one by one, which reduces the convenience of the device and thus results in poor practicality.

A fixing component is installed at the left end of the mounting frame 2. The operator rotates the support rod using the power component, causing multiple sets of evenly distributed stirring blades on the outer side of the support rod to stir the liquid in the aeration tank, promoting liquid mixing. Simultaneously, gas is generated through the air conveying component and transported to the aeration pipe. Finally, multiple sets of evenly distributed nozzles on the outer side of the aeration pipe evenly spray the gas into the aeration tank, increasing the dissolved oxygen content in the liquid and achieving the aeration function. During system operation... In real time, key parameters such as dissolved oxygen content and liquid mixing uniformity in the aeration tank are monitored. The output power of the power unit can be adjusted to change the rotation speed of the drive module, thereby adjusting the stirring speed of the stirring blades to optimize liquid mixing. Simultaneously, the gas flow rate of the air pump can be adjusted to change the aeration volume, achieving precise aeration control to meet the aeration and stirring needs of different processes until the end of operation. When disassembly is required, it can be completed by adjusting the fixing components and then lifting the mounting bracket 2. Integrating aeration and stirring functions into one unit solves the problem of cumbersome disassembly caused by the separate setting of existing stirring and aeration mechanisms.

The left and right ends of the first screw 11 are rotatably connected to one end of the sliding groove of the fixing plate 10, respectively. The first slider 12 is threadedly connected to the first screw 11, and the bottom of the first slider 12 is slidably connected to the sliding groove of the fixing plate 10.

The left end of the mounting frame 2 is evenly provided with two sets of locking holes. The right ends of the two sets of third locking blocks 14 are slidably locked to one set of locking holes of the mounting frame 2, respectively.

[0020] As a preferred embodiment of the above, the power assembly includes a power module 15, an output module 16, a first gear 17, and a second gear 18.

The power of the power module is efficiently transmitted to the first gear through the second gear, thereby driving the support rod to rotate and driving the stirring blades to achieve powerful stirring, providing continuous and stable power support for liquid mixing, thus enhancing practicality.

[0021] As a preferred embodiment of the above, the gas supply assembly includes an air pump device 19, a connecting pipe 20, and an air supply pipe 21. The top outer side of the aeration pipe 8 and the bottom inner side of the connecting pipe 20 are rotatably connected. The right end of the connecting pipe 20 is connected to the left end of the air supply pipe 21. The top right end of the mounting bracket 2 is connected to the bottom of the air pump device 19. The left output end of the air pump device 19 is connected to the right end of the air supply pipe 21. The rotatable connection design between the connecting pipe and the aeration pipe cleverly solves the problem of poor gas delivery that may be caused by the rotation of the aeration pipe during the stirring process, ensuring that the aeration function is not affected when stirring and aeration work together, thus enhancing practicality.

[0022] As a preferred embodiment of the above, the buffer mechanism includes a pressure plate 22, multiple sets of damping rods 23, multiple sets of connecting springs 24, and a guide assembly. The bottom of the groove of the mounting block 4 is uniformly connected to the bottom of the multiple sets of damping rods 23, and the bottom of the pressure plate 22 is uniformly connected to the top of the multiple sets of damping rods 23. A set of connecting springs 24 is respectively provided on the outer side of the multiple sets of damping rods 23. The outer side of the pressure plate 22 is slidably fitted with the groove of the mounting block 4 through the guide assembly, and the top of the pressure plate 22 is in close contact with the bottom of the support rod 5.

[0024] As a preferred embodiment of the above, it also includes a rotating handle 26, with the left end of the first screw 11 passing through the left end of the groove of the fixing plate 10 and connecting to the right end of the rotating handle 26; the operator can easily rotate the rotating handle to operate the fixing component, which significantly improves the convenience of operation, reduces labor intensity, and thus enhances practicality.

[0025] This invention discloses a precise aeration control system. During operation, the power module is activated, outputting power to the drive module, which transmits this power to the second gear. The second gear drives the meshing first gear to rotate, causing the support rod to rotate. This causes multiple sets of evenly arranged stirring blades on the outer side of the support rod to stir the liquid in the aeration tank, promoting mixing. Simultaneously, the air pump is activated, generating gas. This gas is transmitted through a gas delivery pipe to a connecting pipe, and then from the connecting pipe to the aeration pipe. Finally, multiple sets of evenly arranged nozzles on the outer side of the aeration pipe spray the gas evenly into the aeration tank, increasing the dissolved oxygen content in the liquid and achieving aeration. During system operation, key parameters such as dissolved oxygen content and liquid mixing uniformity in the aeration tank are monitored in real time. The output power of the power module can be adjusted to change the rotation speed of the drive module, thereby adjusting the stirring speed of the stirring blades to optimize the liquid mixing effect. The gas flow rate of the air pump can also be adjusted to change the aeration volume, achieving precise aeration control to meet the aeration and stirring requirements of different processes until the end of operation.

[0026] When disassembly is required, turn the rotary handle to rotate the first screw, causing the first slider to slide within the groove of the fixed plate. This moves the connecting plate and the two sets of third locking blocks to the left until the third locking blocks slide out of the mounting bracket's locking holes, releasing the mounting bracket from the aeration tank. Then, the operator lifts the mounting bracket, causing the support rod to disengage the first locking block and the mounting block's locking groove until the support rod is disengaged from the mounting block's groove. This completes the disassembly. Before completing the above actions, the device should first be moved to the user's desired position.

[0028] In this utility model, the terms "first," "second," and "third" do not represent a specific quantity or order, but are merely used to distinguish names.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
