Description

Technical Field

[0001] The utility model relates to the technical field of cyclone aerators, in particular to a multi-nozzle large-flux cyclone aerator. Background Art

[0002] Aerators are essential equipment for aeration and oxygenation of water supply and drainage. They increase the dissolved oxygen content in water by introducing air into the water. The working principle of the aerator is to introduce air into the biochemical aeration tank through appropriate equipment, so that the liquid in the tank comes into contact with the air and becomes oxygenated. This process not only increases the dissolved oxygen in the water, but also helps prevent suspended matter from sinking, strengthens the contact between organic matter and microorganisms, and thus promotes the biodegradation process.

[0003] In the water treatment process, aeration equipment is crucial for aquatic biological pretreatment and sewage biological treatment. They ensure the oxygen supply required for the metabolism of aerobic organisms, and at the same time fully and evenly stir the water in the pool to improve treatment efficiency.

[0004] During actual operation of existing aeration equipment, uneven aeration occurs in the sewage pool, which may cause blockage of the aerator and reduce the oxygen utilization rate of the aerator. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, by installing a splitting component and a blocking component, the bubble generator and the sewage gas generate tiny bubbles. With the rotation of multiple splitting blades, the volume of the tiny bubbles in the aeration cylinder is reduced, making the bubbles smaller and smaller.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 6 The utility model provides a technical solution: a multi-nozzle large-flux cyclone aerator, comprising an aeration cylinder 1 and a segmentation component 2, the segmentation component 2 is arranged inside the aeration cylinder 1, the segmentation component 2 comprises a limit bracket 201, the limit bracket 201 is fixedly connected to both sides of the aeration cylinder 1, a transmission impeller 202 is arranged inside the aeration cylinder 1, a transmission shaft 203 is fixedly connected to the top of the transmission impeller 202, segmentation blades 204 are fixedly connected to both sides of the transmission shaft 203, a cutting blade 205 is arranged on the upper side of the top of the segmentation blade 204, and blocking components 3 are arranged on both sides of the aeration cylinder 1.

[0023] In this embodiment, Figure 1 , Figure 2 and Figure 4As shown, the blocking component 3 includes a bubble generator 301, and the bubble generator 301 is fixedly connected to both sides of the inside of the aeration cylinder 1. A baffle 302 is arranged on the upper side of the top of the bubble generator 301, and guide plates 303 are fixedly connected to both sides of the baffle 302. An air intake component 4 is arranged at the bottom of the aeration cylinder 1. The gas blows the stationary impeller 9 to rotate at the beginning, and the gas rises along the blades of the stationary impeller 9 to generate a strong centrifugal force to make the sewage and air collide and mix violently. The sewage and gas continue to rise, and the gas spirally rises while driving the transmission impeller 202, and the transmission impeller 202 drives the transmission shaft 203, and the transmission shaft 203 drives the dividing blade 204 and the cutting blade 205 to rotate. At this time, the bubble generator 301 and the sewage gas generate tiny bubbles. The rotation of multiple dividing blades 204 assists in dividing the high-pressure gas and sewage, reducing the volume of tiny bubbles in the aeration cylinder 1, making the bubbles smaller and smaller, and ejected from the outflow port 6. Due to the vacuum negative pressure at the bottom of the aeration cylinder 1, the ejected mixed flow can re-enter the aeration process for circulation, increasing the retention time of tiny bubbles in the sewage and improving the oxygen utilization rate. The installed multiple cutting blades 205 crush the sludge in the sewage, and the crushed sludge and high-pressure air achieve the best mixing state and the longest retention time, so that the sludge impurities in the sewage are more fully treated aerobically, and there is no sludge deposition in the whole process. When the air intake is stopped, the check valve core 804 falls back without being affected by the gas, blocking the double-nozzle air intake pipe to prevent water backflow.

[0024] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the air intake assembly 4 includes an air intake joint 401, which is fixedly connected to the bottom of the aeration cylinder 1, and the two sides of the air intake joint 401 are fixedly connected to double-nozzle air intake pipes 402, and the outer side of the double-nozzle air intake pipe 402 is fixedly connected to a fixed flange 403.

[0025] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the air inlet joint 401 is fixedly connected to a water inlet pipe 5 , an outflow port 6 is provided at the top of the aeration cylinder 1 , and a connecting component 7 is provided on the outside of the aeration cylinder 1 .

[0026] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the connecting component 7 includes a first lifting ear 701, the first lifting ear 701 is fixedly connected to the outer side of the aeration cylinder 1, the outer side of the aeration cylinder 1 is sleeved with a reinforcement ring 702, the outer side of the reinforcement ring 702 is fixedly connected with a second lifting ear 703, and check assemblies 8 are arranged on both sides of the inside of the air inlet joint 401. When using the device, the staff installs the device inside the sewage pool through the first lifting ear 701 and the second lifting ear 703, and the gas enters the air inlet joint 401 through the double-nozzle air inlet pipe 402. When the gas enters the air inlet joint 401, the check valve core 804 is pushed open, and the check valve core 804 drives the slider 802 to slide upward along the slide rail 801, and at the same time, the sewage enters the air inlet joint 401 through the water inlet pipe 5.

[0027] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the check assembly 8 includes a slide rail 801, which is fixedly connected to both sides of the inside of the air inlet connector 401, the inner cavity of the slide rail 801 is slidably connected to a slider 802, the bottom of the slider 802 is fixedly connected to a connecting rod 803, the top of the connecting rod 803 is fixedly connected to a check valve core 804, and the inside of the air inlet connector 401 is fixedly connected to a stationary impeller 9.

[0028] The use method and advantages of the utility model: When the multi-nozzle large-flux cyclone aerator is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when using the device, the staff installs the device inside the sewage pool through the first lifting ear 701 and the second lifting ear 703, and the gas enters the air inlet joint 401 through the double-nozzle air inlet pipe 402. When the gas enters the air inlet joint 401, the check valve core 804 is pushed open, and the check valve core 804 drives the slider 802 to slide upward along the slide rail 801. At the same time, the sewage enters the air inlet joint 401 through the water inlet pipe 5. The gas further blows the stationary impeller 9 to start rotating. When the gas rises along the blades of the stationary impeller 9 and generates a strong centrifugal force, the sewage and air collide and mix violently, and the sewage and gas continue to rise. While the gas spirally rises, it drives the transmission impeller 202, and the transmission impeller 202 drives the transmission shaft 203, and the transmission shaft 203 drives the dividing blade 204 and the cutting blade 205 to rotate. At this time, the gas The bubble generator 301 and the sewage gas generate tiny bubbles, and as the multiple dividing blades 204 rotate, they play an auxiliary role in dividing the high-pressure gas and the sewage, reducing the volume of the tiny bubbles in the aeration cylinder 1, making the bubbles smaller and smaller, and ejected from the outflow port 6. Due to the vacuum negative pressure at the bottom of the aeration cylinder 1, the ejected mixed flow can re-enter the aeration process for circulation, increasing the retention time of the tiny bubbles in the sewage and improving the oxygen utilization rate. The installed multiple cutting blades 205 crush the sludge in the sewage, and the crushed sludge and high-pressure air reach the best mixing state and the longest retention time, so that the sludge impurities in the sewage are more fully treated aerobically, and there is no sludge deposition in the whole process. When the air intake is stopped, the check valve core 804 falls back without being affected by the gas, blocking the double nozzle air intake pipe to prevent water backflow.
