Description

Technical Field

[0001] This utility model relates to the technical field of degreasing wastewater treatment, specifically a treatment device for degreasing wastewater from aluminum alloy components. Background Technology

[0002] Degreasing wastewater from aluminum alloy components refers to industrial wastewater generated during the aluminum alloy processing, after the use of alkaline or acidic cleaning agents, surfactants, and other degreasing agents to remove oil, grease, and impurities from the surface of the components. Its typical characteristics include high levels of grease, suspended solids, acidic and alkaline components, and possibly small amounts of metal ions and organic additives. It is a complex industrial wastewater with high pollutant concentrations and requires specialized treatment before discharge or reuse.

[0003] Currently, the treatment of degreasing wastewater usually adopts the air flotation separation method. The compressed air released from the bottom forms an upward airflow, which will significantly agitate and mix the water, removing emulsified oil and suspended solids. This is a common treatment method.

[0004] Currently, when using air flotation separation for treatment, the air inlets are mostly fixed, making it impossible to dynamically adjust the compressed air intake according to changes in the real-time oil content, suspended solids concentration, and other operating conditions of the wastewater. When the air intake is insufficient, it leads to inadequate gas-liquid contact, uneven bubble dispersion, poor demulsification effect, and difficulty in effectively separating suspended solids. Excessive air intake results in energy waste and may also damage the stability of the wastewater treatment system.

[0005] In addition, although some devices attempt to adjust the ventilation volume, they rely heavily on additional sensors, controllers and other auxiliary components, which not only further increases the complexity of the equipment and the risk of failure, but also results in a delayed adjustment response and an inability to coordinate with the stirring action. Utility Model Content

[0006] The purpose of this invention is to provide a treatment device for degreasing wastewater from aluminum alloy components, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A device for treating degreasing wastewater from aluminum alloy components includes a wastewater treatment tank and a drive motor connected to the top of the wastewater treatment tank. A rotating shaft and multiple sets of agitating blades for stirring the wastewater are connected to the output shaft of the drive motor. A circular outer shell and a transmission plate disposed within the circular outer shell are connected to the bottom of the wastewater treatment tank. The transmission plate is fixedly disposed at the bottom of the rotating shaft. A centrifugal mechanism is provided on the transmission plate. The centrifugal mechanism cooperates with a tilting assembly fixed within the circular outer shell. A housing and a venting assembly are connected to the bottom of the circular outer shell. An air supply assembly is provided at one end of the wastewater treatment tank.

[0009] The aluminum alloy component degreasing wastewater treatment device described above: the centrifugal mechanism includes slots opened at both ends of the transmission plate and a column connected to the slots, and a sliding counterweight is slidably installed on the column.

[0010] The aluminum alloy component degreasing wastewater treatment device described above: each of the two columns is fitted with a first spring, and the first spring abuts against the sliding counterweight on the side.

[0011] The aluminum alloy component degreasing wastewater treatment device described above: the bottom of the sliding counterweight is connected to a connecting column and a second spring sleeved on the connecting column, and a sloping slider is slidably installed at the bottom of the connecting column, with the second spring abutting against the sloping slider.

[0012] The aluminum alloy component degreasing wastewater treatment device described above: the flipping assembly includes a support frame connected to the circular outer shell and a flipping disc rotatably mounted on the support frame, with two inclined sliders cooperating with the flipping disc.

[0013] The above-mentioned treatment device for degreasing wastewater of aluminum alloy components: the ventilation component includes a cylinder connected inside the shell and an air vent opened on the cylinder. A cover is slidably installed on the outside of the cylinder. One end of the cover is connected to a connecting rod, and the connecting rod is rotatably connected to a rotating disc.

[0014] The aluminum alloy component degreasing wastewater treatment device described above: the air supply component includes a booster pump located at one end of the wastewater treatment tank and a pipe located on one side of the booster pump. The pipe is connected to the bottom of the cylinder. One end of the top of the shell is connected to an air jet pipe, and the end of the air jet pipe extends into the interior of the wastewater treatment tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The output shaft of the stirring motor works in conjunction with a centrifugal actuator. When the motor starts and accelerates, the centrifugal force drives the slider to move radially, lifting the bottom cover through a linkage mechanism. This proportionally opens the circumferential vent, enabling the aeration volume of compressed air to increase synchronously and precisely linearly with the stirring speed. This achieves intelligent matching and synergistic effect between stirring intensity and aeration volume. Under high pollutant load conditions, the high-speed stirring and a large number of microbubbles work together to form intense fluid shearing and efficient air flotation separation, significantly improving demulsification and oil removal efficiency. During low-load periods, the system automatically enters a low-speed, low-volume energy-saving mode.

[0017] This invention achieves an adaptive and precise match between stirring intensity and aeration volume. When the wastewater pollutant concentration is high and requires intensive treatment, the high motor speed provides both intense stirring and shearing and a large number of microbubbles. The synergistic effect of these two factors greatly enhances the demulsification, mass transfer, and air flotation separation effects. Conversely, when the load is low, the device automatically enters an energy-saving mode with low speed and low air volume. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Please see Figures 1-13 As an embodiment of this utility model, the treatment device for degreasing wastewater of aluminum alloy components includes a wastewater treatment tank 1 and a drive motor 2 connected to the top of the wastewater treatment tank 1. A rotating shaft 3 and multiple sets of stirring blades 4 for stirring wastewater are connected to the output shaft of the drive motor 2. A circular outer shell 5 and a transmission plate 6 disposed inside the circular outer shell 5 are connected to the bottom of the wastewater treatment tank 1. The transmission plate 6 is fixedly disposed at the bottom of the rotating shaft 3. A centrifugal mechanism is provided on the transmission plate 6. The centrifugal mechanism cooperates with a flipping component fixed inside the circular outer shell 5. A housing 13 and a ventilation component connected inside the housing 13 are connected to the bottom of the circular outer shell 5. An air supply component is provided at one end of the wastewater treatment tank 1.

[0034] In this embodiment, the degreasing wastewater treatment device innovatively sets a stirring motor on the wastewater treatment tank 1, and fixes the centrifugal mechanism and the motor coaxially. The centrifugal force generated by the motor operation drives the slider to slide outward, thereby adjusting the air supply volume of the air supply component. The motor speed and the air supply volume form a precise linkage. The faster the speed, the greater the centrifugal force, which causes the subsequent compressed air introduction volume to increase synchronously, realizing the adaptive and precise matching of stirring intensity and aeration volume.

[0035] As a further embodiment of this utility model, the centrifugal mechanism includes slots formed at both ends of the transmission plate 6 and a column connected to the slots, with a sliding counterweight 7 slidably mounted on the column.

[0036] In this embodiment, when the transmission plate 6 rotates rapidly with the motor shaft, the centrifugal force generated by it will cause the sliding counterweights 7 on both sides to be thrown to the outside.

[0037] As a further embodiment of this utility model, a first spring 8 is fitted on each of the two columns, and the first spring 8 abuts against the sliding counterweight 7 on the side.

[0038] In this embodiment, when the two sliding counterweights 7 are thrown to the outermost position, the first spring 8 can generate an elastic force, and the sliding of the sliding counterweights 7 will cause the first spring 8 to be compressed.

[0039] As a further embodiment of this utility model, the bottom of the sliding counterweight 7 is connected to a connecting column and a second spring 10 sleeved on the connecting column. A slanted slider 9 is slidably installed at the bottom of the connecting column, and the second spring 10 abuts against the slanted slider 9.

[0040] In this embodiment, the bottom of the sliding counterweight 7 moves synchronously with the inclined slider 9, and the inclined slider 9 slides up and down onto the connecting column. The inclined slider 9 can slide on the connecting column, and the second spring 10 provides elastic restoring force for the inclined slider 9.

[0041] As a further embodiment of this utility model, the flipping assembly includes a support frame 11 connected to the circular outer shell 5 and a flipping disk 12 rotatably mounted on the support frame 11, with both inclined sliders 9 cooperating with the flipping disk 12.

[0042] In this embodiment, the support frame 11 is fixed inside the circular outer shell 5, the flip disk 12 is rotatably mounted on the top of the support frame 11, and the inclined slider 9 is in a pressing fit with the flip disk 12.

[0043] As a further embodiment of this utility model, the ventilation assembly includes a cylinder 17 connected inside the housing 13 and an air vent opened on the cylinder 17. A cover 18 is slidably installed on the outside of the cylinder 17, and a connecting rod 19 is connected to one end of the cover 18. The connecting rod 19 is rotatably connected to the rotating disc 12.

[0044] In this embodiment, the housing 13 is fixed to the bottom of the circular outer shell 5, the cylinder 17 has multiple sets of vents along the axial direction, the cover 18 slides outside the cylinder 17 and can block the vents, the cover 18 is rotatably connected to the rotating disc 12 via the connecting rod 19, and when the rotating disc 12 is rotated, it can drive the cover 18 to slide upward via the connecting rod 19.

[0045] As a further embodiment of this utility model, the air supply assembly includes a booster pump 15 disposed at one end of the wastewater treatment tank 1 and a pipe 16 disposed on one side of the booster pump 15. The pipe 16 is connected to the bottom of the cylinder 17, and a jet pipe 14 is connected to one end of the top of the shell 13. The end of the jet pipe 14 extends into the interior of the wastewater treatment tank 1.

[0046] In this embodiment, the centrifugal force generated by the motor drives the two sliding counterweights 7 to slide outward, compressing the first spring 8 and rotating accordingly. At the same time, the inclined sliders 9 at the bottom slide outward synchronously. During high-speed rotation, the two inclined sliders 9 will rotate on the outermost side. At this time, the bottom rotating disc 12 is squeezed, causing the rotating disc 12 to rotate. The two inclined sliders 9 maintain alternating contact with the rotating disc 12 at all times to maintain the state of the rotating disc 12. The rotating disc 12 drives the cover 18 to slide upward through the connecting rod 19. During the process, the vent of the cylinder 17 will gradually be exposed. The more the cover 18 slides, the more air is released from the vent. The gas will be introduced into the jet pipe 14 through the shell 13, and then the jet pipe 14 will spray the gas into the bottom of the wastewater treatment tank 1. Under high pollutant load conditions, high-speed stirring and a large number of microbubbles work together to form intense fluid shearing and efficient air flotation separation, significantly improving the demulsification and oil removal efficiency. During low-load periods, the system automatically enters a low-speed, low-volume energy-saving mode.

[0047] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
