Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, and more particularly to a retractable tubular aerator. Background Technology

[0002] Aeration is a common process in water treatment. Common aeration gases include air, ozone, and oxygen. Ozone technology is a water treatment process with multiple functions such as disinfection, oxidation of pollutants, and reaction of large molecules into smaller molecules. Ozone contact tanks are usually divided into 2-3 sections: first aeration, then a reaction zone, then aeration again, and then another reaction zone. Ozone / hydrogen peroxide technology is an advanced oxidation water treatment process that mainly relies on the free radicals generated to react with pollutants. In ozone / hydrogen peroxide advanced oxidation tanks, the influent usually passes through a guide wall for a period of time for aeration, then hydrogen peroxide is added before entering the reaction zone.

[0003] Ozone processes require dispersed ozone aeration over a smaller area, thus requiring fewer tubular aerators. Ozone / hydrogen peroxide processes, on the other hand, require concentrated ozone aeration at the front end, necessitating a larger aeration area and thus requiring more tubular aerators. Since the same water treatment tank frequently switches between ozone and ozone / hydrogen peroxide processes, a sufficient number of tubular aerators are typically installed to meet operational needs. However, this practice leads to overflow of the total efficiency of the tubular aerators when using the ozone process, necessitating the shutdown of some aerators and wasting equipment resources. Furthermore, the repeated shutdown and restarting of some tubular aerators also affects their working efficiency.

[0004] Therefore, it is necessary to propose improvements to the retractable tubular aerator to save equipment resources and improve the working efficiency of the tubular aerator. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the existing tubular aerators are too numerous when installed, resulting in waste of equipment resources and affecting the working efficiency of the tubular aerators. A telescopic tubular aerator is now provided.

[0006] The technical solution of this invention is:

[0007] A telescopic tubular aerator includes a sleeve and an aeration rod placed inside the sleeve. A piston is provided inside the sleeve and is sleeved on the outside of the aeration rod. One end of the sleeve is open, and the aeration rod between the piston and the opening can be aerated. The other end of the sleeve is provided with a sealing cap, which forms a sealing area with the piston to restrict the aeration of the aeration rod in this area. A telescopic rod is provided between the sealing cap and the piston, and the telescopic rod drives the piston to move axially along the aeration rod.

[0008] Furthermore, it also includes aeration heads placed outside the sleeve. When the telescopic rod retracts, the aeration heads aerate. Because the telescopic rod drives the piston to move, and the telescopic rods currently on the market, whether pneumatic or electric, have limited strokes and are shorter than the length of traditional aeration pipes, while the length of the aeration rod on this device matches the stroke of the telescopic rod, the length of the aeration rod with the telescopic rod installed is shorter than the length of a traditional aeration pipe. Therefore, even if the aeration range of the aeration rod of this device is adjusted to the maximum, it is still smaller than the aeration range of a traditional aeration pipe. To compensate for this deficiency without affecting the piston's adjustment effect on the aeration range, the aeration heads are added. The aeration heads can aerate independently outside the sleeve, further expanding the aeration range, while not occupying a large ground area, making them highly practical.

[0009] Furthermore, a sliding tube is provided between the sealing cap and the piston. The sliding tube is sleeved on the outside of the aeration rod. A sliding hole is provided on the sealing cap for the sliding tube to pass through. One end of the sliding tube is fixedly connected to the piston. The sliding tube is slidably connected to the sliding hole. The sliding tube moves axially synchronously with the piston. The sliding tube can provide support for the piston, satisfy the structural stability of the piston in the sleeve, and enable the piston to move axially stably.

[0010] Furthermore, it also includes a bogie placed outside the casing. The aeration head is fixedly mounted on the bogie, which is equipped with a lever located on the sliding tube's movement path. When the telescopic rod retracts, the sliding tube pushes the lever to move, causing the aeration head on the bogie to change from a horizontal to a vertical orientation. When performing ozone / hydrogen peroxide processes, a larger aeration range is required. At this time, the telescopic rod retracts, driving the piston to move towards the sealing cover, expanding the aeration range of the aeration rod. Simultaneously, the sliding tube moves outward through the sliding hole, pushing the lever to move. The lever drives the bogie to rotate, thus turning the aeration head. When the aeration head is vertically upward, it begins to aerate, further increasing the aeration range in conjunction with the aeration rod.

[0011] Furthermore, it also includes a collection chamber. When the aeration head is in a horizontal position, it is located in the collection chamber. There is a lot of sludge and impurities in the sewage treatment tank. When the aeration head is in a horizontal position, it is not in working state. At this time, the sludge and impurities in the water are easy to accumulate on the aeration head and block it. The collection chamber can cover and protect the aeration head, prevent the accumulation of sludge and impurities, and improve the use effect and service life of the aeration head.

[0012] Furthermore, the aeration surface of the aeration head is an arc surface, the opening of the storage chamber faces horizontally, and the interior of the storage chamber is an arc shape that matches the aeration surface. The arc surface of the aeration surface allows for easy turning, and the arc shape inside the storage chamber that matches the aeration surface can avoid obstructing the aeration head when it rotates.

[0013] Furthermore, the storage compartment is equipped with bristles that face the aeration head. The bristles can brush away sludge and impurities on the aeration surface when the aeration head rotates, ensuring the aeration effect of the aeration head.

[0014] Furthermore, multiple aeration heads are provided, arranged in a straight line on the bogie. The multiple aeration heads can expand the aeration range and ensure the usage requirements.

[0015] Furthermore, the sliding tube has a buckle at one end opposite to the lever that matches the lever. When the telescopic rod retracts, the sliding tube pushes the lever to move and simultaneously squeezes the lever into the buckle. When the telescopic rod extends, the sliding tube pulls the lever back to its original position through the buckle, thereby disengaging the lever from the buckle. The buckle ensures the lever's reset, allowing the bogie to turn smoothly when the sliding tube moves into the sleeve, so that the aeration head rotates back into the collection chamber.

[0016] Furthermore, the telescopic rod is fixedly installed on the sealing cover.

[0017] The retractable tubular aerator of this invention can reduce the aeration range required for ozone processes when the required aeration area is small. In this case, the telescopic rod moves the piston along the aeration rod, reducing the distance between the piston and the opening, thus narrowing the aeration range on the aeration rod. Conversely, for ozone / hydrogen peroxide processes, when a larger aeration range is required, the telescopic rod moves the piston along the aeration rod, increasing the distance between the piston and the opening, thus expanding the aeration range on the aeration rod. The aeration rod in the sealed area between the sealing cap and the piston will not come into contact with water and will not generate aeration due to the sealing effect. By adjusting the position of the piston, the aeration range of the aeration rod can be flexibly controlled, eliminating the need to repeatedly start and stop parts of the tubular aerator. Compared with traditional technologies, this technical solution saves equipment resources and improves the working efficiency of the tubular aerator. Attached Figure Description

[0026] To make the technical means, technical features, inventive purpose and technical effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0027] Example 1:

[0028] like Figure 1 As shown, this embodiment provides a retractable tubular aerator, including a sleeve 1 and an aeration rod 2 placed inside the sleeve 1. The sleeve 1 is a rigid pipe, but a flexible pipe can also be used. When the sleeve 1 is a rigid pipe, as shown... Figure 2 As shown, when sleeve 1 is a soft pipe, as Figure 3 As shown, a bracket 15 is installed inside the sleeve 1 to support the shaped sleeve 1; a piston 3 is provided inside the sleeve 1, and the piston 3 is sleeved on the outside of the aeration rod 2. One end of the sleeve 1 is an opening 4, through which sewage can enter the sleeve 1. The aeration rod 2 between the piston 3 and the opening 4 can be aerated. The other end of the sleeve 1 is provided with a sealing cap 5, which forms a sealing area with the piston 3 to restrict the aeration of the aeration rod 2 here. A telescopic rod 6 is provided between the sealing cap 5 and the piston 3. The telescopic rod 6 drives the piston 3 to move axially along the aeration rod 2. Preferably, the telescopic rod 6 is fixedly installed on the sealing cap 5 with screws. Preferably, the telescopic rod 6 is a pneumatic telescopic rod 6, and the telescopic head of the pneumatic telescopic rod 6 is fixedly connected to the piston 3 with screws. The aeration rod 2 is a perforated rigid aeration rod 2, which is connected to the ozone generating system to introduce ozone into the aeration rod 2. The aeration rod 2 is fixedly connected to the sleeve 1 with screws.

[0029] When performing ozone processing, a smaller aeration range is required. In this case, the telescopic rod 6 moves the piston 3 along the aeration rod 2, reducing the distance between the piston 3 and the opening 4, thus narrowing the aeration range on the aeration rod 2. When performing ozone / hydrogen peroxide processing, a larger aeration range is required. In this case, the telescopic rod 6 moves the piston 3 along the aeration rod 2, increasing the distance between the piston 3 and the opening 4, thus expanding the aeration range on the aeration rod 2. The aeration rod 2 in the sealed area between the sealing cover 5 and the piston 3 will not come into contact with water and will not produce an aeration effect due to the sealing effect. By adjusting the position of the piston 3, the aeration range of the aeration rod 2 can be flexibly controlled, eliminating the need to repeatedly start and stop some tubular aerators. Compared with traditional technology, this technical solution saves equipment resources and improves the working efficiency of tubular aerators.

[0030] Example 2:

[0031] like Figure 4 As shown, this embodiment provides a retractable tubular aerator, including a sleeve 1 and an aeration rod 2 placed inside the sleeve 1. The sleeve 1 is a rigid pipe, but a flexible pipe can also be used. When the sleeve 1 is a rigid pipe, as shown... Figure 2 As shown, when sleeve 1 is a soft pipe, as Figure 3 As shown, a bracket 15 is installed inside the sleeve 1 to support the shaped sleeve 1; a piston 3 is provided inside the sleeve 1, and the piston 3 is sleeved on the outside of the aeration rod 2. One end of the sleeve 1 is an opening 4, through which sewage can enter the sleeve 1. The aeration rod 2 between the piston 3 and the opening 4 can be aerated. The other end of the sleeve 1 is provided with a sealing cap 5, which forms a sealing area with the piston 3 to restrict the aeration of the aeration rod 2 here. A telescopic rod 6 is provided between the sealing cap 5 and the piston 3. The telescopic rod 6 drives the piston 3 to move axially along the aeration rod 2. Preferably, the telescopic rod 6 is fixedly installed on the sealing cap 5 with screws. Preferably, the telescopic rod 6 is a pneumatic telescopic rod 6, and the telescopic head of the pneumatic telescopic rod 6 is fixedly connected to the piston 3 with screws. The aeration rod 2 is a perforated rigid aeration rod 2, which is connected to the ozone generating system to introduce ozone into the aeration rod 2. The aeration rod 2 is fixedly connected to the sleeve 1 with screws.

[0032] When performing ozone processing, a smaller aeration range is required. In this case, the telescopic rod 6 moves the piston 3 along the aeration rod 2, reducing the distance between the piston 3 and the opening 4, thus narrowing the aeration range on the aeration rod 2. When performing ozone / hydrogen peroxide processing, a larger aeration range is required. In this case, the telescopic rod 6 moves the piston 3 along the aeration rod 2, increasing the distance between the piston 3 and the opening 4, thus expanding the aeration range on the aeration rod 2. The aeration rod 2 in the sealed area between the sealing cover 5 and the piston 3 will not come into contact with water and will not produce an aeration effect due to the sealing effect. By adjusting the position of the piston 3, the aeration range of the aeration rod 2 can be flexibly controlled, eliminating the need to repeatedly start and stop some tubular aerators. Compared with traditional technology, this technical solution saves equipment resources and improves the working efficiency of tubular aerators.

[0033] Preferred, such as Figure 5As shown, it also includes an aeration head 7 placed outside the sleeve 1. When the telescopic rod 6 retracts, the aeration head 7 aerates. Since the telescopic rod 6 drives the piston 3 to move, and the telescopic rod 6 currently on the market, whether pneumatic or electric, has a limited stroke, it is shorter than the length of traditional aeration pipes. The length of the aeration rod 2 on this device matches the stroke of the telescopic rod 6. Therefore, the length of the aeration rod 2 with the telescopic rod 6 installed is less than the length of traditional aeration pipes. So even if the aeration range of the aeration rod 2 on this device is adjusted to the maximum, it is still less than the aeration range of traditional aeration pipes. In order to make up for this deficiency without affecting the adjustment effect of the piston 3 on the aeration range, the aeration head 7 is added. The aeration head 7 can aerate independently outside the sleeve 1, further expanding the aeration range, while not occupying a large ground area, and has high practicality.

[0034] Preferred, such as Figure 4 As shown, a sliding tube 8 is provided between the sealing cover 5 and the piston 3. The sliding tube 8 is sleeved on the outside of the aeration rod 2. A sliding hole 9 is provided on the sealing cover 5 for the sliding tube 8 to pass through. One end of the sliding tube 8 is fixedly connected to the piston 3. The sliding tube 8 is slidably connected to the sliding hole 9. The sliding tube 8 moves axially synchronously with the piston 3. The sliding tube 8 can provide support for the piston 3, satisfy the structural stability of the piston 3 in the sleeve 1, and enable the piston 3 to move axially stably. Sealing measures are taken between the sliding tube 8 and the sliding hole 9, such as adding a sealing gasket, to ensure the sealing of the area between the piston 3 and the sealing cover 5. The aeration rod 2 and the sliding tube 8 are coaxial. The end of the aeration rod 2 where the sealing cover 5 is located can slide relative to the sliding tube 8, and sealing measures are taken between the two, such as adding a sealing gasket.

[0035] Preferred, such as Figure 5 and Figure 7 As shown, it also includes a bogie 10 placed outside the sleeve 1. The bogie 10 is fixedly installed on the outside of the sleeve 1 by screws or welding. The aeration head 7 is fixedly installed on the bogie 10 by screws. The bogie 10 is provided with a lever 11, which is fixed on the bogie 10 by screws or welding. The lever 11 is located on the moving path of the sliding tube 8. When the telescopic rod 6 retracts, the sliding tube 8 pushes the lever 11 to move, causing the aeration head 7 on the bogie 10 to turn from horizontal to vertical. When performing ozone / hydrogen peroxide process, a larger aeration range is required. At this time, the telescopic rod 6 retracts, driving the piston 3 to move towards the sealing cover 5, expanding the aeration range of the aeration rod 2. At the same time, the sliding tube 8 moves to the outside of the sleeve 1 through the sliding hole 9 and pushes the lever 11 to move. The lever 11 drives the bogie 10 to rotate, realizing the turning of the aeration head 7. When the aeration head 7 is vertically upward, the aeration head 7 starts to aerate, which, together with the aeration rod 2, further increases the aeration range.

[0036] Preferred, such as Figure 5As shown, it also includes a collection chamber 12, which is fixed to one side of the bogie 10 of the sleeve 1 by screws or welding. When the aeration head 7 is in the horizontal direction, it is located in the collection chamber 12. There is a lot of sludge and impurities in the sewage treatment tank. When the aeration head 7 is in the horizontal direction, it is not in working state. At this time, the sludge and impurities in the water are easy to accumulate on the aeration head 7 and block the aeration head 7. The collection chamber 12 can cover and protect the aeration head 7, prevent the accumulation of sludge and impurities, and improve the use effect and service life of the aeration head 7.

[0037] Preferred, such as Figure 5 As shown, the aeration surface of the aeration head 7 is an arc surface, the opening 4 of the storage chamber 12 faces the horizontal direction, and the inside of the storage chamber 12 is an arc shape that matches the aeration surface. The arc surface of the aeration surface can be easily turned, and the arc shape inside the storage chamber 12 that matches the aeration surface can avoid obstructing the aeration head 7 when it rotates.

[0038] Preferred, such as Figure 5 As shown, brush bristles 13 are glued or screwed into the storage compartment 12. The brush bristles 13 are opposite to the aeration head 7. When the aeration head 7 rotates, the brush bristles 13 can brush away the sludge and impurities on the aeration surface, ensuring the aeration effect of the aeration head 7.

[0039] Preferred, such as Figure 6 As shown, multiple aeration heads 7 are provided, and the multiple aeration heads 7 are arranged in a straight line on the bogie 10. The multiple aeration heads 7 can expand the aeration range and ensure the usage requirements.

[0040] Preferred, such as Figure 6 As shown, the sliding tube 8 has a buckle 14 at one end opposite to the lever 11, which matches the lever 11. When the telescopic rod 6 retracts, the sliding tube 8 pushes the lever 11 to move and simultaneously squeezes the lever 11 into the buckle 14. When the telescopic rod 6 extends, the sliding tube 8 pulls the lever 11 back to its original position through the buckle 14, thereby disengaging the lever 11 from the buckle 14. The buckle 14 ensures the reset of the lever 11, allowing the bogie 10 to turn smoothly when the sliding tube 8 moves into the sleeve 1, so that the aeration head 7 can rotate back into the collection chamber 12.
