Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment aerator. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] The existing Chinese patent announcement number CN219620928U, entitled "A Wastewater Treatment Aerator," explicitly states in its abstract that "This utility model provides a wastewater treatment aerator, relating to the field of wastewater treatment, including an aeration device, an air inlet pipe, and a spray pipe. A spray pipe is provided on one side of the aeration device, and an air inlet pipe is provided at the top of the spray pipe on one side. A leather bag is provided around the spray pipe via clamps, and a locking block is provided at one end of each clamp. A fixing bolt is provided between the locking blocks at one end of each clamp. During the use of this utility model, if the aeration device is in operation, the high-speed water flow from the spray nozzle can open the leather bag. The open leather bag will not affect the water flow from the spray pipe for aeration. After aeration, the leather bag returns to its original shape after losing the impact force of the water flow from the spray pipe, becoming a flat bag. At this time, debris and impurities in the wastewater are difficult to pass through the flat bag and enter the spray pipe, causing scaling or blockage on the inner wall of the spray pipe, thus increasing the practicality of this device."

[0004] However, in this technology, the leather bag may be easily worn, broken or aged due to long-term impact from high-speed water flow and the chemical substances in sewage, requiring regular replacement, which is somewhat inconvenient to operate. Although the leather bag can prevent some debris and impurities from entering the nozzle, it may be difficult to block some smaller particles or sticky substances, which may still enter the nozzle and cause the risk of clogging the nozzle. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment aerator to solve the problems mentioned in the background art, such as the need for regular replacement of the filter bags and the difficulty in blocking some smaller particles or sticky substances.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wastewater treatment aerator includes an aeration device, an air inlet pipe, a spray pipe, and an installation sleeve. A connecting component is provided at the end of the spray pipe, and a baffle component is provided inside the installation sleeve.

[0008] The connecting assembly includes an external thread, and a rotating sleeve is rotatably disposed on the front of the mounting sleeve.

[0009] The baffle assembly includes a second spring, on which a baffle is provided, and the mounting sleeve is provided with aeration ports around its perimeter.

[0010] In a preferred embodiment of this utility model, the inner side of the rotating sleeve is provided with an internal thread, and the internal thread is threadedly connected to the external thread.

[0011] In a preferred embodiment of this utility model, a hexagonal post is provided on one side of the external thread, and a first spring is provided on the outside of the hexagonal post.

[0012] In a preferred embodiment of this utility model, the top of the first spring is provided with an internal hexagonal slider, which is slidably connected to the hexagonal column.

[0013] In a preferred embodiment of this utility model, a rotating component is rotatably provided on the outer side of the internal hexagonal slider, and a limit block is provided on one side of the bottom of the rotating component.

[0014] In a preferred embodiment of this utility model, a limiting port is provided on one side of the outer side of the rotating sleeve, and the limiting block is installed and removed in the limiting port.

[0015] In a preferred embodiment of this utility model, the second spring is connected to the rear of the inner side of the mounting sleeve, and the partition is slidably connected to the mounting sleeve.

[0016] In a preferred embodiment of this utility model, a blocking net is provided on the aeration port, and the front of the blocking member is in contact with the nozzle.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0018] Beneficial effects: The blocking net blocks large particles of impurities. Under normal conditions, the second spring pushes the baffle, causing its outer side to contact the inner wall of the aeration port. This blocks smaller impurities outside the aeration port. The baffle also contacts the nozzle, effectively blocking it. This double blocking, compared to a leather bag, effectively reduces and prevents small impurities from entering the nozzle and causing blockages. When the aeration equipment is running, the high-speed water flow from the nozzle can open the baffle, causing the second spring to contract and open the aeration port, thus not affecting aeration. After aeration, the second spring pushes the baffle again. The mounting sleeve and its internal structure are made of corrosion-resistant metal, effectively reducing the frequency of replacement.

[0019] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please refer to Figures 1-4This utility model discloses a wastewater treatment aerator, including an aeration device 1, an air inlet pipe 11, a spray pipe 12, and an installation sleeve 3. The aeration device 1, air inlet pipe 11, and spray pipe 12 are the aeration devices, air inlet pipes, spray pipes, etc., as described in the background technology patent. This patent improves the structure at the end of the spray pipe. The installation sleeve 3 is the installation structure. A connecting component is provided at the end of the spray pipe 12. The connecting component includes an external thread 13. A rotating sleeve 31 is rotatably provided at the front of the installation sleeve 3. An internal thread 32 is provided on the inner side of the rotating sleeve 31. The internal thread 32 is threadedly connected to the external thread 13, that is, the external thread 13 is connected through the internal thread 32, so that the installation sleeve 3 is installed at the end of the spray pipe 12. The installation sleeve 3 and its internal structure are made of corrosion-resistant metal material, which can effectively reduce the frequency of replacement.

[0028] A hexagonal post 2 is provided on one side of the external thread 13. A first spring 22 is provided on the outside of the hexagonal post 2. An internal hexagonal slider 21 is provided on the top of the first spring 22. The first spring 22 is always in the state of pulling the internal hexagonal slider 21 downward. The internal hexagonal slider 21 is slidably connected to the hexagonal post 2. A rotating part 23 is rotatably provided on the outside of the internal hexagonal slider 21. A limit block 24 is provided on one side of the bottom of the rotating part 23. A limit port 33 is provided on one side of the outside of the rotating sleeve 31. The limit block 24 is installed and removed in the limit port 33. After the installation sleeve 3 is installed, the limit block 24 is installed in the limit port 33. 4. The device will connect to the limiting port 33. At this time, the first spring 22 pulls the hexagonal slider 21, so that the limiting block 24 is inserted into the limiting port 33. At this time, the rotating sleeve 31 cannot rotate, thus effectively preventing the connection between the installation sleeve 3 and the nozzle 12 from becoming loose. When the rotating sleeve 31 is rotating, the limiting block 24 is moved to the other side by rotating the rotating part 23 in advance, thus avoiding affecting the rotation of the rotating sleeve 31. After the rotating sleeve 31 is installed, the rotating part 23 is pulled upward and rotated to its original position.

[0029] The mounting sleeve 3 has an internal baffle assembly, which includes a second spring 42. A baffle 43 is mounted on the second spring 42. Aeration ports 4 are arranged around the perimeter of the mounting sleeve 3. The second spring 42 is connected to the rear interior of the mounting sleeve 3. The baffle 43 is slidably connected to the mounting sleeve 3. A blocking net 41 is mounted on the aeration port 4 to block large particles of impurities. The front of the baffle 43 contacts the nozzle 12. Under normal conditions, the second spring 42 pushes the baffle 43, causing the outer side of the baffle 43 to contact the aeration port. When the aeration port 4 is in contact with the inner wall, it can block smaller impurities on the outside of the aeration port 4. The front of the baffle 43 is in contact with the nozzle 12, which effectively blocks the nozzle 12. Through double blocking, impurities are effectively prevented from entering the nozzle 12 and causing blockage. When the aeration equipment 1 is in operation, the high-speed water flow sprayed from the nozzle of the nozzle 12 can push the baffle 43 open, thus opening the aeration port 4 and not affecting the aeration work. When the aeration work is over, the second spring 42 pushes the baffle 43 again.

[0030] The working principle of this utility model is as follows: The internal thread 32 connects to the external thread 13, allowing the mounting sleeve 3 to be installed at the end of the nozzle 12. When the rotating sleeve 31 rotates, the rotating component 23 is rotated in advance, causing the limiting block 24 to move to the other side. After the mounting sleeve 3 is installed, the rotating component 23 is pulled upwards and rotated back to its original position. At this time, the limiting block 24 aligns with the limiting port 33. The first spring 22 pulls the internal hexagonal slider 21, causing the limiting block 24 to insert into the limiting port 33. At this point, the rotating sleeve 31 cannot rotate, effectively preventing loosening of the connection between the mounting sleeve 3 and the nozzle 12. The blocking net 41 is used for... To block large particles of impurities, under normal conditions, the second spring 42 pushes the baffle 43, causing the outer side of the baffle 43 to contact the inner wall of the aeration port 4. This blocks smaller impurities on the outer side of the aeration port 4. Furthermore, the front of the baffle 43 contacts the spray pipe 12, effectively blocking the spray pipe 12. Through this double blocking, impurities are effectively prevented from entering the spray pipe 12 and causing blockage. When the aeration device 1 is in operation, the high-speed water flow from the nozzle of the spray pipe 12 can open the baffle 43, thus opening the aeration port 4 without affecting the aeration operation. After the aeration operation is completed, the second spring 42 pushes the baffle 43 again.
