Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment device and an aeration device thereof. Background Art

[0002] As we all know, wastewater treatment often involves oxygenation, and the most commonly used oxygen supply is a microporous aeration disc, which is connected to the aeration pipe at the bottom of the pool via a saddle. To prevent corrosion, the aeration disc (including the gland, aeration membrane, and base), saddle, and bottom aeration pipe are generally made of non-metallic materials. Currently, the main sealing connection method for aeration heads is threaded, with a threaded connection between the gland and base, and a threaded connection between the aeration head inlet pipe and the saddle.

[0003] The main problems with threaded connections are as follows: First, because polymer plastics are relatively soft, their threads will be damaged to a certain extent when tightened. Once disassembled, they are difficult to tighten again. Damage to the threads will make the aerator difficult to reuse, reducing the service life of the aerator. Second, the short life of threaded connections is due to plastic creep (creep refers to the continuous, irreversible deformation of polymer materials over time under continuous stress). During installation, the degree of tightening causes the force on the threads to far exceed the elastic deformation range. Excessive tightening causes the thread teeth to creep and deform. After years of continuous creep, the threads are difficult to reset after disassembly. Utility Model Content

[0004] Based on this, it is necessary to provide a wastewater treatment device and an aeration device thereof to address the problem that the threaded connection between the aeration head air inlet pipe and the saddle seat is easily damaged and creeps, resulting in the aeration equipment being unable to be reused.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] In one embodiment, the wastewater treatment device comprises Figure 1 The aeration device shown includes a saddle seat 10 and an aeration plate 20 , and the saddle seat 10 is installed on an aeration cross pipe 30 .

[0037] The aeration plate 20 has an air inlet pipe 21 , which is sealed to the saddle 10 via a socket structure 40 , so that the gas in the aeration cross pipe 30 can flow into the aeration plate 20 through the saddle 10 and the air inlet pipe 21 in sequence.

[0038] Specifically, the spigot structure 40 includes a spigot portion 41 and a bell portion 42, with the spigot portion 41 inserted into the bell portion 42. The inlet pipe 21 may have a smaller outer diameter to form the spigot portion 41, while the outlet pipe of the saddle seat 10 may have a larger inner diameter to form the bell portion 42. Alternatively, the inlet pipe 21 may have a larger inner diameter to form the bell portion 42, while the outlet pipe of the saddle seat 10 may have a smaller outer diameter to form the spigot portion 41.

[0039] A sealing ring 43 is provided around the socket portion 41. When the socket portion 41 is inserted into the bell portion 42, the sealing ring 43 seals the gap between the two. In one embodiment, the socket portion 41 has an annular groove formed on its surface, and the sealing ring 43 is fitted within the groove. A portion of the sealing ring 43 is located within the groove, while a portion of the sealing ring 43 is exposed outside the socket portion 41. When the socket portion 41 and bell portion 42 are connected, the sealing ring 43, squeezed by the inner and outer walls, provides a seal, preventing gas leakage from the pipe or water from outside the pipe from seeping into the aeration pipe.

[0040] The socket portion 41 and the bell portion 42 are provided with an axial limiting structure 50 to prevent the two from slipping, and the axial limiting structure 50 connects the socket portion 41 and the bell portion 42 in a detachable manner. Figure 2 As shown, in one embodiment, the axial limiting structure 50 includes a connecting plate 51 and a connector 52. The connecting plate 51 is arranged on the socket portion 41. The connecting plate 51 is provided with a snap-in hole 511. The connector 52 is arranged on the socket portion 42. The connector 52 is inserted into the snap-in hole 511.

[0041] In one embodiment, the connector 52 is an elastic hook 521. The inner diameter of the engaging hole 511 is increased to form a step. The step serves as the buckle 512. The elastic hook 521 engages with the buckle 512 to achieve a detachable connection between the connector 52 and the connecting plate 51. The elastic hook 521 can be designed as one or two as needed. Figure 3 As shown, when there are two elastic hooks 521, the two elastic hooks 521 are designed to face each other, or face each other, and the two elastic hooks 521 have a gap between them to provide space for the elastic hooks 521 to deform, and two buckles 512 are correspondingly designed in the snap-in hole 511.

[0042] Please also refer to Figure 4 In another embodiment, the connector 52 includes a connecting rod 522 and a pin 523. The connecting rod 522 is provided on the outer wall of the socket portion 42. A pin hole is provided at the top of the connecting rod 522. After the socket portion 41 is inserted into the socket portion 42, the pin hole is coaxial with the engaging hole 511 on the connecting plate 51. At this time, the pin 523 is inserted into the pin hole and the engaging hole 511 to achieve a detachable connection between the socket portion 41 and the socket portion 42.

[0043] See also Figure 5In one embodiment, the axial limiting structure 50 may also adopt other forms. Specifically, the axial limiting structure 50 includes a spigot flange 53, a bell flange 54, and a connector 55. The spigot flange 53 is provided on the spigot portion 41, and the bell flange 54 is provided on the bell portion 42. The connector 55 detachably connects the spigot flange 53 and the bell flange 54 to achieve a detachable connection between the spigot portion 41 and the bell portion 42.

[0044] Specifically, both the spigot flange 53 and the bell flange 54 are provided with a connecting hole 56 extending through the spigot flange 53 and the bell flange 54 in the axial direction. After the spigot portion 41 is inserted into the bell portion 42, the spigot flange 53 and the bell flange 54 are docked, and the connecting holes 56 on the spigot flange 53 and the bell flange 54 correspond one to one. The connecting member 55 can be a bolt, the screw of the bolt being passed through the connecting holes 56 of the spigot flange 53 and the bell flange 54 in sequence and then being fastened with a nut.

[0045] Please also refer to Figure 6 Alternatively, the connector 55 is a positioning pin having enlarged snap-fit joints 551 at both ends. A deformation groove is provided at one end of the positioning pin to enable compression and deformation of the end of the positioning pin. When the positioning pin needs to be inserted into the connecting hole 56, the compressed end of the positioning pin is inserted into the connecting hole 56. After the positioning pin passes through the connecting hole 56, the snap-fit joints 551 compressed by the positioning pin expand and become larger. The snap-fit joints 551 at both ends of the positioning pin engage with the socket flange 54 and the spigot flange 53, thereby achieving a detachable connection between the spigot flange 53 and the socket flange 54.

[0046] See also Figure 7 Alternatively, the connecting member 55 is a clamp, which is provided with a receiving groove 552 for accommodating the socket flange 53 and the socket flange 54, so as to clamp the socket flange 53 and the socket flange 54 in the receiving groove 552, and connect the socket flange 53 and the socket flange 54 detachably.

[0047] Please also refer to Figure 8 , wherein the clamp includes a first fixing ring 553 and a second fixing ring 554, and the first fixing ring 553 and the second fixing ring 554 are hinged. After the socket part 41 is inserted into the socket part 42 and the socket flange 53 and the socket flange 54 are connected, the clamp is unfolded so that the socket flange 53 and the socket flange 54 are located in the accommodating groove 552, and then after the first fixing ring 553 and the second fixing ring 554 of the clamp are connected, the first fixing ring 553 and the second fixing ring 554 are locked and fixed with bolts.

[0048] See also Figure 4 and Figure 9In one embodiment, a vibration-damping pad 60 is provided on the horizontal overlapping surface of the bell portion 42 and the socket portion 41. The vibration-damping pad 60 can prevent the bell portion 42 from colliding with the flange of the socket portion 41 or the connecting plate 51 during the insertion of the socket portion 41 into the bell portion 42. At the same time, the vibration-damping pad 60 can play a positioning role, positioning the depth of the socket portion 41 inserted into the bell portion 42. The elasticity of the vibration-damping pad 60 can also reduce the vibration between the structures and ensure that the distance between the two remains stable, preventing frequent collisions and damage between the connectors 55. Specifically, the vibration-damping pad 60 can be made of rubber or silicone. The socket flange 53 and the bell flange 54 can be a whole disc shape, or a partial disc, a rectangle, etc.

[0049] like Figure 9 As shown, in one embodiment, due to the design of the spigot flange 53 and the bell flange 54, the base of the aerator 20 is shaped to be smaller in the middle and larger at both ends. The saddle seat 10 is also shaped to be smaller in the middle and larger at both ends. Since the saddle seat 10 and the base are plastic parts, the base and the saddle seat 10 are not easy to remove from the mold during production. Therefore, in this embodiment, the bell portion 42 and the bell flange 54 are integrally formed, and the spigot portion 41 and the spigot flange 53 are integrally formed.

[0050] At least one of the parts between the bell mouth 42 and the air inlet pipe 21 and between the socket 41 and the saddle seat 10 is designed separately. That is, the bell mouth 42 and the air inlet pipe 21 can be designed separately, while the socket 41 and the saddle seat 10 can be designed separately; or the bell mouth 42 and the air inlet pipe 21 can be designed separately, while the socket 41 and the saddle seat 10 can be designed as a whole; or the bell mouth 42 and the air inlet pipe 21 can be designed as a whole, while the socket 41 and the saddle seat 10 can be designed separately.

[0051] Of course, it is also possible to have at least one of the two groups of separate designs between the bell portion 42 and the saddle seat 10 and between the socket portion 41 and the air intake pipe 21. That is, the bell portion 42 and the saddle seat 10 are designed separately, and the socket portion 41 and the air intake pipe 21 are designed separately; or the bell portion 42 and the saddle seat 10 are designed separately, and the socket portion 41 and the air intake pipe 21 are designed as a whole; or the bell portion 42 and the saddle seat 10 are designed as a whole, and the socket portion 41 and the air intake pipe 21 are designed as separate parts.

[0052] Because the socket portion 42 and the socket flange 54 are integrally formed, and the socket portion 41 and the socket flange 53 are integrally formed, and the socket portion 41 and the socket portion 42 are designed separately from the base and the saddle seat 10, the base and the saddle seat 10 do not have a structure that is small in the middle and large at both ends. The base and the saddle seat 10 do not have the problem of inconvenience in demolding during the production process, which is conducive to reducing production costs and improving production efficiency. The connection between the socket portion 41 and the socket portion 42 and the base and the air intake pipe 21 can be welded, bonded, or threaded after being sleeved.

[0053] In one embodiment, a speed-limiting pipe 70 is installed within the gas passage formed by the inlet pipe 21, the socket structure 40, and the saddle 10. The speed-limiting pipe 70 primarily controls the resistance to gas entering the various aeration discs 20, ensuring a more uniform gas output from each disc 20. Furthermore, if the aeration membrane of a disc 20 ruptures, air will not escape through the damaged section of the pipe, thereby impacting the oxygenation of other discs 20. Specifically, in this embodiment, the speed-limiting pipe 70 has an inner diameter of 4-8 mm and a length of 10-100 mm.

[0054] In one embodiment, the base of the aeration plate 20 and the air inlet pipe 21 are preferably made of polymer materials such as ABS, PE, PP, and fiberglass. The saddle seat 10 and the aeration cross pipe 30 are preferably made of ABS, PE, PP, 304, and 316.

[0055] In the above-mentioned wastewater treatment device and aeration device thereof, the socket portion 41 is inserted into the socket portion 42 and the gap between the two is sealed by the sealing ring 43, which can prevent air from escaping from the gap between the two. The socket portion 41 and the socket portion 42 are detachably connected by an axial limiting structure 50. When the aeration disc 20 needs to be removed, the fixing of the socket portion 41 and the socket portion 42 by the axial limiting structure 50 is released, and the aeration disc 20 can be removed so as to repair or replace the aeration disc 20. When installing the aeration disc 20, the socket portion 41 is inserted into the socket portion 42, and then the socket portion 41 and the socket portion 42 are fixed by the axial limiting structure 50. The aeration disc 20 is easy to install and disassemble, has a high reuse rate, and reduces the time of shutdown and maintenance.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
