Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an aeration device for an integrated wastewater treatment system. Background Technology

[0002] The core objective of wastewater treatment is to purify wastewater to meet the water quality requirements for discharge into water bodies or for reuse. It treats wastewater containing organic matter, inorganic matter, suspended solids, and pathogens, including domestic sewage and industrial wastewater, with the aim of protecting water resource quality and public health.

[0003] Aeration devices are used in wastewater treatment. These devices drive aeration impellers via a stirring shaft to achieve thorough mixing of wastewater and air and oxygen transfer, playing a decisive role in the efficiency of the biodegradation process. However, during prolonged use, aeration impellers may accumulate solid impurities from the wastewater or be corroded by the wastewater. When disassembling, replacing, or maintaining the aeration impeller is necessary, it is often inconvenient and inefficient, thus reducing the practicality of the device. To address these issues, this application proposes an aeration device for an integrated wastewater treatment system. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides an aeration device for an integrated sewage treatment equipment, which is easy to clean.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aeration device for an integrated sewage treatment equipment, comprising a support base, a driver provided on the top of the support base, an insertion mechanism provided on the outside of the driver, a limit mechanism provided on the outside of the insertion mechanism, and an aeration impeller provided on the outside of the insertion mechanism.

[0006] The limiting mechanism includes a support arm, which is disposed outside the insertion mechanism. A threaded rod is rotatably connected to the inner side of the support arm. A threaded block is threadedly connected to the outer wall of the threaded rod. A support plate is fixedly connected to the left side of the threaded block. A locking block is fixedly connected inside the support plate.

[0007] Preferably, the threads on the outer walls of the two ends of the threaded rod are in opposite directions, and a torsion sleeve is fixedly connected to the outer wall of the threaded rod to facilitate the rotation of the threaded rod through the torsion sleeve.

[0008] Preferably, the support arm has a sliding opening inside, and the threaded block is slidably connected to the inner wall of the sliding opening to stably limit the position of the threaded block.

[0009] Preferably, the insertion mechanism includes an internal spline, which is fixedly connected to one end of the aeration impeller. A protrusion is fixedly connected to the outer wall of the internal spline. A fixing plate is fixedly connected to the outer wall of the driver. A fixing groove is fixedly connected to one side of the fixing plate. An external spline is fixedly connected to the outer wall of the driver. The fixing groove is fixedly connected to one side of the support arm, which facilitates better rotation and aeration of the aeration impeller.

[0010] Preferably, the top of the fixed groove has a movable opening, through which the card block passes, allowing the card block to move.

[0011] Preferably, the outer wall of the outer spline meshes with the inner wall of the inner spline, and the protrusion is slidably connected to the inner wall of the fixing groove to support the aeration impeller.

[0012] Preferably, a slot is provided on one side of the external spline, and the locking block is movably connected to the inner wall of the slot, so that the locking block can limit the protrusion through the slot, thereby preventing the aeration impeller from moving.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this utility model, the limiting mechanism allows the locking block to be pulled out from the slot of the protrusion, thus removing the limiting effect on the protrusion and facilitating further disassembly of the aeration impeller. When the aeration impeller needs to be disassembled, replaced, or maintained, good disassembly efficiency is achieved, enhancing the practicality of the device and also achieving good disassembly and assembly efficiency.

[0015] In this invention, the inner spline is pulled out from the inside of the outer spline through the insertion mechanism, and the protrusion can be pulled out from the inside of the fixing groove, thus enabling the disassembly of the aeration impeller. Similarly, the inner spline is inserted into the outer wall of the outer spline for engagement, and the protrusion is inserted into the inside of the fixing groove, so that the output shaft of the driver can drive the aeration impeller to rotate, thereby achieving the purpose of stable rotational aeration. This also facilitates further disassembly and assembly operations, improving the flexibility of the device.

[0016] Other additional advantages and benefits of this application 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 this application. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figures 1-4 The present invention provides the following technical solution: an aeration device for an integrated sewage treatment equipment, including a support base 1, a driver 2 is provided on the top of the support base 1, an insertion mechanism 3 is provided on the outside of the driver 2, a limit mechanism 4 is provided on the outside of the insertion mechanism 3, and an aeration impeller 5 is provided on the outside of the insertion mechanism 3.

[0026] The limiting mechanism 4 includes a support arm 41, which is located outside the insertion mechanism 3. A threaded rod 42 is rotatably connected to the inner side of the support arm 41. A threaded block 43 is threadedly connected to the outer wall of the threaded rod 42. A support plate 44 is fixedly connected to the left side of the threaded block 43. A locking block 45 is fixedly connected inside the support plate 44.

[0027] The threads on the outer walls of the two ends of the threaded rod 42 are in opposite directions. A torsion sleeve is fixedly connected to the outer wall of the threaded rod 42, which facilitates the rotation of the threaded rod 42 through the torsion sleeve.

[0028] The support arm 41 has a sliding opening inside, and the threaded block 43 is slidably connected to the inner wall of the sliding opening to stabilize and limit the position of the threaded block 43.

[0029] Preferably, by Figure 1 and Figure 2As shown, in this embodiment, the insertion mechanism 3 includes an internal spline 31, which is fixedly connected to one end of the aeration impeller 5. A protrusion 33 is fixedly connected to the outer wall of the internal spline 31. A fixing plate 35 is fixedly connected to the outer wall of the driver 2. A fixing groove 34 is fixedly connected to one side of the fixing plate 35. An external spline 32 is fixedly connected to the outer wall of the driver 2. The fixing groove 34 is fixedly connected to one side of the support arm 41, so that the aeration impeller 5 can rotate and aerate better.

[0030] The top of the fixed groove 34 has a movable opening, through which the locking block 45 passes, allowing the locking block 45 to move.

[0031] The outer wall of the outer spline 32 meshes with the inner wall of the inner spline 31, and the protrusion 33 is slidably connected to the inner wall of the fixing groove 34 to support the aeration impeller 5.

[0032] A slot is provided on one side of the external spline 32, and a locking block 45 is movably connected to the inner wall of the slot, so that the locking block 45 can limit the protrusion 33 through the slot, thereby preventing the aeration impeller 5 from moving.

[0033] Components not described in detail in this article are existing technologies.

[0034] The working principle and usage process of this utility model are as follows: First, the device is placed inside the sewage treatment tank by the support base 1. Then, the driver 2 can be started. The output shaft of the driver 2 can drive the aeration impeller 5 to rotate through the cooperation of the external spline 32 and the internal spline 31, so that the aeration impeller 5 can turn over the sewage inside the sewage treatment tank, thereby achieving the purpose of aeration.

[0035] During prolonged use, when it is necessary to disassemble, clean, maintain, or replace the aeration impeller 5, the torsion sleeve on the outer wall of the threaded rod 42 can be rotated to drive the threaded rod 42 to rotate. Since the threads on the outer walls at both ends of the threaded rod 42 are in opposite directions, the rotational motion of the threaded rod 42 is converted into the linear motion of the threaded block 43. The threaded block 43 can be moved through the support plate 44 with the locking block 45, allowing the locking block 45 to be pulled out from the slot opened in the protrusion 33, thus removing the limit on the protrusion 33. This facilitates further disassembly of the aeration impeller 5. When it is necessary to disassemble, replace, or maintain the aeration impeller 5, good disassembly efficiency is achieved, enhancing the practicality of the device, while also achieving good disassembly and assembly efficiency.

[0036] When the limiting position of the protrusion 33 is removed, the inner spline 31 can be pulled out from the inside of the outer spline 32 through the aeration impeller 5, and the protrusion 33 can be pulled out from the inside of the fixing groove 34, thus realizing the disassembly of the aeration impeller 5. Similarly, the inner spline 31 is inserted into the outer wall of the outer spline 32 for engagement, and the protrusion 33 is inserted into the inside of the fixing groove 34, so that the output shaft of the driver 2 can drive the aeration impeller 5 to rotate, thereby achieving the purpose of stable rotational aeration. Similarly, it also facilitates further disassembly and assembly operations, improving the flexibility of the device.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
