Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, specifically to an anti-clogging swirl aerator head. Background Technology

[0002] Currently, widely used air aeration devices in wastewater treatment include flexible aerators with variable orifice, microporous aeration discs, and diaphragm aeration heads. Their working principle is that high-pressure air is ejected from the micropores and mixed with wastewater to provide oxygen. The main drawback is that the air flow resistance is large, which leads to a decrease in oxygenation efficiency and an increase in pressure loss.

[0003] The micropores on the surface of the aeration head are prone to clogging or enlargement, which can lead to aging of the device and a significantly shortened lifespan. This is especially true in wastewater treatment facilities with high sludge concentrations. Existing wastewater treatment equipment has significant shortcomings in terms of energy efficiency and anti-clogging capabilities. During prolonged aeration, floating scale can adhere to the inner wall of the cylinder, affecting the aeration effect. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-clogging swirl aerator head to solve the above-mentioned defects caused by the prior art.

[0005] A clog-resistant swirl aerator head includes a cylinder, a bubble generating roller, a cutting disc, and brush strips. A base is provided on the outer side of the cylinder, and a flange tray is provided at the bottom of the base. A pneumatic mechanism is located directly above the flange tray. The pneumatic mechanism drives the bottom of the bubble generating roller to rotate. The rotating blades generate a centrifugal force field, causing the liquid or suspended solids to separate under centrifugal force. A cleaning mechanism is provided inside the cylinder. The bubble generating roller cuts impurities in the wastewater through the cutting disc at its bottom, while the brush strips simultaneously clean the dirt inside the cylinder, preventing large amounts of dirt from adhering to the inside of the cylinder and causing blockages during long-term operation.

[0006] Preferably, the pneumatic mechanism includes an air inlet box, a flange interface, a drive shaft, a bubble generating roller, blades, and an impeller. The impeller is disposed inside the air inlet box, a portion of the air inlet box is connected to a cylinder, a flange interface is connected to one side of the air inlet box, a drive shaft is connected to the outside of the air inlet box, a bubble generating roller is connected to the outside of the drive shaft, multiple sets of blades are disposed on the outside of the bubble generating roller, and the inner end of the impeller is keyed to the outside of the drive shaft.

[0007] Preferably, the bubble generating roller is connected to the outer side of the impeller via a drive shaft that passes through the outer side.

[0008] Preferably, the cleaning mechanism includes a cutting disc, a vertical groove, an aeration disc, a brush strip, and a vertical retaining strip. The cutting disc is located at the bottom of the inner part of the cylinder. The bottom of the drive shaft is keyed to the outer side of the cutting disc. A vertical groove is provided on the outer side of the bubble generating roller. A vertical retaining strip is connected to the outer side of the vertical groove. A vertical retaining strip is connected to one side of the vertical retaining strip. A brush strip is connected to one side of the vertical retaining strip. The aeration disc pipe is connected to both sides of the air inlet box.

[0009] Preferably, the bubble generating roller is connected to the outer side of the vertical clip through a vertical groove provided on the outer side, and the length of the vertical clip is greater than the length of the brush strip.

[0010] Preferably, the impeller is connected to a drive shaft and a slitting disc via an inner key, and the contact end of the drive shaft with the air inlet box is connected by a bearing.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The slitting disc at the bottom of the cylinder is used to cut and crush solid impurities in the sewage at high speed when the roller rotates. The centrifugal force breaks down large particles into small fragments. Compressed air is released through the micropores on the surface of the roller to form a cluster of microbubbles. As the bubbles rise, they carry the crushed impurities to the surface, accelerating solid-liquid separation. At the same time, the vertical groove on the outside of the cylinder is connected to the brush strip. The brush strip removes the adhering sludge and fiber impurities by rotating and rubbing against the inner wall of the cylinder.

[0013] The impeller drives the bubble generating roller and blades to rotate synchronously via shaft drive. Gas drives the impeller to achieve self-circulation of mechanical energy, reducing external energy consumption. The rotation speed of the impeller is controlled by the gas flow rate. The aeration discs on both sides receive residual gas from the compression system and discharge it directly into the wastewater. The aeration discs adopt a microporous structure to release tiny bubbles to increase dissolved oxygen transfer efficiency. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, an anti-clogging swirl aerator head includes a cylinder 1, a bubble generating roller 8, a cutting disc 11, and brush strips 15. A base 2 is provided on the outer side of the cylinder 1, and a flange tray 3 is provided at the bottom end of the base 2. A pneumatic mechanism 6 is provided directly above the flange tray 3. The pneumatic mechanism 6 drives the bottom end of the bubble generating roller 8 to rotate. The rotating blades 9 generate a centrifugal force field, causing the liquid or suspended matter to separate under centrifugal action. A cleaning mechanism 10 is provided inside the cylinder 1. The bubble generating roller 8 cuts and processes impurities in the sewage through the cutting disc 11 at the bottom end, and at the same time, the brush strips 15 are used to brush the dirt inside the cylinder 1, avoiding a large amount of dirt adhering to the inside of the cylinder 1 and causing blockage during long-term operation.

[0023] In this embodiment, the pneumatic mechanism 6 includes an air inlet box 4, a flange interface 5, a drive shaft 7, a bubble generating roller 8, blades 9, and an impeller 12. The impeller 12 is disposed inside the air inlet box 4. A portion of the air inlet box 4 is connected to a cylinder 1. A flange interface 5 is connected to one side of the air inlet box 4. The drive shaft 7 is connected to the outside of the air inlet box 4. The bubble generating roller 8 is connected to the outside of the drive shaft 7. Multiple sets of blades 9 are disposed on the outside of the bubble generating roller 8. The inner end of the impeller 12 is keyed to the outside of the drive shaft 7. While driving the bubble generating roller 8 through the air inlet box 4, the oxidation rate in the wastewater is increased by the discharged ozone or air.

[0024] In this embodiment, the bubble generating roller 8 is connected to the outer side of the impeller 12 via a drive shaft 7 that passes through its outer side. The impeller 12 drives the bubble generating roller 8 to rotate, thereby controlling the rotation speed of the bubble generating roller 8.

[0025] In this embodiment, the cleaning mechanism 10 includes a cutting disc 11, a vertical groove 13, an aeration disc 14, a brush strip 15, and a vertical retaining strip 16. The cutting disc 11 is located at the bottom of the inner part of the cylinder 1. The bottom of the drive shaft 7 is keyed to the outer side of the cutting disc 11. The outer side of the bubble generating roller 8 is provided with a vertical groove 13. The outer side of the vertical groove 13 is connected to a vertical retaining strip 16. A vertical retaining strip 16 is connected to one side of the vertical retaining strip 16. A brush strip 15 is connected to one side of the vertical retaining strip 16. The aeration disc 14 is pipe-connected to both sides of the air inlet box 4.

[0026] In this embodiment, the bubble generating roller 8 is connected to the outer side of the vertical clip 16 via the vertical groove 13 provided on the outer side. The length of the vertical clip 16 is greater than the length of the brush strip 15. The vertical groove 13 is used to position and disassemble one side of the brush strip 15, which facilitates the replacement and maintenance of the brush strip 15.

[0027] In this embodiment, the impeller 12 is connected to the slitting disc 11 via an inner key, and the contact end of the drive shaft 7 with the air inlet box 4 is connected by a bearing. The drive shaft 7 drives the slitting disc 11 to rotate, thereby crushing the residual solids in the sewage.

[0028] In practical applications, this type of anti-clogging swirl aerator head includes the following functions:

[0029] Step 1: First, install the flange tray 3 at the bottom of the cylinder 1 inside the sewage tank, so that the flange tray 3 is connected and positioned with the overhead structure in the sewage tank, so that the bottom of the cylinder 1 comes into contact with the sewage, allowing a portion of the sewage to be injected into the inside of the cylinder 1. Then, directly connect the flange interface 5 to the compressed air pipe, so that the compressed gas from the outside is injected into the inside of the air inlet box 4. The high-pressure gas impacts the blades of the impeller 12, causing it to rotate at high speed. The impeller 12 acts as an energy conversion hub, converting the pressure energy of the gas into rotational kinetic energy.

[0030] Step 2: The impeller 12 drives the bubble generating roller 8 and blades 9 to rotate synchronously through the drive shaft 7 set on the outside. The rotation of the blades 9 generates strong shearing force, crushes solid impurities in the sewage, and promotes the micro-mixing of gas and liquid through eddy current, making the bubble distribution more uniform. At the same time, the aeration disc 14 can be connected to both sides of the air inlet box 4 through pipe fittings, so that the aeration discs 14 on both sides receive the residual gas from the inside of the air inlet box 4 and discharge it directly into the sewage.

[0031] Step 3: The bottom end of the cylinder 1 is connected to the cutting disc 11 through the drive shaft 7. When the drive shaft 7 rotates, the cutting disc 11 cuts and crushes the solid impurities in the sewage at high speed. The centrifugal force decomposes the large particles into small fragments. Compressed air is released through the micropores on the surface of the roller to form a group of microbubbles. During the rise of the bubbles, the crushed impurities float to the surface, which accelerates the solid-liquid separation.

[0032] Step 4: After a period of use, the operator aligns the brush strip 15 on the outer side of the vertical clamping strip 16 with the vertical clamping groove 13, inserts the vertical clamping strip 16 into the vertical clamping groove 13, and then positions the vertical clamping groove 13 and the vertical clamping strip 16 with bolts. Subsequently, the brush strip 15 is connected to the outer side of the bubble generating roller 8. By rotating the brush strip 15, the sticky sludge in the cylinder 1 is removed through friction, thereby preventing sludge from adhering and causing blockage inside the cylinder 1.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
