Description

Technical Field

[0001] The utility model belongs to the technical field of sewage aeration, and in particular relates to energy-saving aeration equipment. Background Art

[0002] Aeration refers to the process of forcibly transferring oxygen from the air into the liquid in order to obtain sufficient dissolved oxygen. In addition, aeration also prevents the suspended matter in the pool from sinking and strengthens the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, thereby ensuring that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. Cyclone aeration is a wastewater treatment technology based on fluid dynamics as its core principle. It uses a multi-layer spiral cutting structure to crush bubbles into microbubbles, significantly improving the oxygen transfer efficiency.

[0003] The existing cyclone aerator generates bubbles by rotating the bubble generator inside the cylinder to react with the water. Since the bubble generator rotates in one direction, some gas cannot collide with the generator to generate bubbles, resulting in gas waste and increasing the energy consumption of the aerator.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] It will be understood that the terms "first" and "second" used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

[0032] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0033] like Figures 1 to 6 As shown, an energy-saving aeration device provided by an embodiment of the utility model includes:

[0034] A fixed base 1 is provided with a cylinder 2, and a vertical guide plate 21 and an air inlet pipe 22 are fixedly provided on the inner wall of the cylinder 2;

[0035] The bubble cutting assembly 3 is provided on the cylinder 2 and is used to cut the bubbles. The bubble cutting assembly 3 includes:

[0036] The positive cutting shaft 31 is rotatably engaged with the cylinder 2. The positive cutting shaft 31 is connected to the reverse cutting shaft 35 via a reversing mechanism 34. The reverse cutting shaft 35 is also rotatably engaged with the cylinder 2.

[0037] The gas-liquid driving blade 32 is fixedly mounted on the outer wall of the cutting shaft 31 and is used to drive the cutting shaft 31;

[0038] The positive bubble cutter 33 is fixedly mounted on the outer wall of the positive cutting shaft 31 above the gas-liquid driving blade 32;

[0039] The anti-bubble cutter 36 is fixedly mounted on the anti-cutting shaft 35. The rotation direction of the anti-bubble cutter 36 is opposite to the rotation direction of the positive bubble cutter 33.

[0040] Specifically, as a further embodiment of the present invention, the reversing mechanism 34 includes:

[0041] The sealing shell 341 is fixedly mounted on the inner wall of the cylinder 2, and the positive cutting shaft 31 is also rotatably engaged with the sealing shell 341;

[0042] The spur gear 342 is fixedly mounted on the shaft end of the spur cutting shaft 31;

[0043] The transmission gear 343 is meshed with the spur gear 342 and is also rotatably coupled to the sealing housing 341 via the first rotating shaft.

[0044] The driving gear 344 is meshed with the transmission gear 343 and is also rotatably coupled to the sealing housing 341 via a second rotating shaft;

[0045] The counter gear 345 is fixedly mounted on the shaft end of the counter cutting shaft 35 . The counter gear 345 is also meshed with the driving gear 344 . The counter cutting shaft 35 is rotatably matched with the sealing housing 341 .

[0046] In the embodiment of the present utility model, in actual application, the device is installed in a sewage treatment pool, and the air inlet pipe 22 is connected to the air supply equipment. The air enters the cylinder 2 and mixes with the liquid to drive the gas-liquid driving blade 32 to rotate, driving the positive cutting shaft 31 to rotate, so that the positive bubble cutter 33 cuts the air. At this time, the air flows upward through the vertical guide plate 21, and the spur gear 342 is driven by the positive cutting shaft 31. The reverse cutting shaft 35 is rotated by the meshing force between the transmission gear 343, the driving gear 344 and the reverse gear 345, and the reverse cutting shaft 35 rotates in the opposite direction to the positive cutting shaft 31. The reverse cutting shaft 35 drives the reverse bubble cutter 36 to cut the air again. The air first undergoes a clockwise cutting force and then a counterclockwise cutting force, which has a better effect on air cutting and improves the efficiency of sewage aeration.

[0047] The vertical guide plate 21 and the bubble cutting assembly 3 are arranged to achieve clockwise and counterclockwise cutting of the gas. This design increases the chance of collision between the gas and the bubble cutting assembly 3, improves the probability of the gas being cut, and avoids the situation where part of the gas is not cut into bubbles due to unidirectional flow, thereby reducing energy consumption and cost during the sewage aeration process.

[0048] It should be noted that the spur gear 342, transmission gear 343, drive gear 344 and counter gear 345 can be stainless steel gears or plated gears. As long as the gears can maintain waterproof and corrosion-resistant effects, the applicant does not make too many restrictions here.

[0049] like Figures 1 to 6 As shown, as a further embodiment of the present invention, the number of vertical guide plates 21 is two groups, which are respectively arranged on the inner wall surface of the cylinder 2 near the positive bubble cutter 33 side and the inner wall surface of the cylinder 2 near the negative bubble cutter 36 side, and the number of vertical guide plates 21 in each group is several;

[0050] In the embodiment of the present invention, in actual application, a large number of vertical guide plates 21 can guide the gas so that the gas can be cut better during its flow.

[0051] like Figures 1 to 6As shown, as a further embodiment of the present invention, a plurality of groups of positive cutting knife mechanisms 331 are fixedly mounted on the positive bubble cutter 33, and positive guide grooves 332 are provided on the positive bubble cutters 33 between adjacent positive cutting knife mechanisms 331, and each group of the positive cutting knife mechanisms 331 includes a plurality of positive bubble cutters, and a plurality of groups of reverse cutting knife mechanisms 361 are fixedly mounted on the reverse bubble cutter 36, and reverse guide grooves 362 are provided on the reverse bubble cutters 36 between adjacent reverse cutting knife mechanisms 361, and each group of the reverse cutting knife mechanisms 361 includes a plurality of reverse bubble cutters;

[0052] In the embodiment of the present invention, in actual application, when the positive bubble cutter 33 and the negative bubble cutter 36 rotate to cut the gas, due to the presence of the positive guide groove 332 and the negative guide groove 362, the gas flow time will be increased, thereby increasing the probability of being cut by the positive cutting knife mechanism 331 and the negative cutting knife mechanism 361, and improving the efficiency of bubble cutting.

[0053] like Figures 1 to 6 As shown, as a further embodiment of the present invention, a mounting tube 11 is fixedly installed on one side of the fixing base 1 close to the cylinder 2. A floating airbag 12 is also installed on the fixing base 1. The floating airbag 12 is connected to the mounting tube 11. The floating airbag 12 is located in a water storage chamber provided in the fixing base 1. Holes 13 are provided on the side and bottom of the fixing base 1, and the holes 13 are connected to the water storage chamber.

[0054] In the embodiment of the present invention, in actual application, the mounting tube 11 is connected to an air pump or other air supply equipment to inflate the floating airbag 12, so that the floating airbag 12 expands to increase the buoyancy effect of the device, making it easier to disassemble the device.

[0055] like Figures 1 to 6 As shown, as a further embodiment of the present invention, a filter hole 23 is further provided at the bottom of the cylinder 2, and a fixed brush 37 is fixedly mounted on the free end of the cutting shaft 31 for cleaning the filter hole 23;

[0056] In the embodiment of the present invention, in actual application, the rotation of the cutting shaft 31 will simultaneously drive the fixed brush 37 to rotate, cleaning the filter holes 23 of the cylinder 2 to prevent impurities in the sewage from clogging the filter holes 23, thereby achieving a better effect of mixing and flowing gas and sewage.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
