Description

Technical Field

[0001] This utility model relates to the field of aeration head technology, specifically a membrane aeration head for sewage treatment. Background Technology

[0002] Aeration heads are a practical tool in aerobic biological wastewater treatment. The main function of aeration heads is to promote the exchange of matter between gases and liquids. This is achieved through strong contact between air and water, dissolving oxygen from the air into the water, or expelling unwanted gases and volatile substances from the water into the air. By enhancing the contact between water and air, the mass transfer of oxygen from the gas phase to the liquid phase is promoted.

[0003] Upon investigation, a novel self-cleaning aeration head with publication number CN207973581U was found, which includes an aeration chamber shell and an aeration membrane fixedly tensioned on the opening surface of the aeration chamber shell. This is used to solve the problem of blockage caused by sediment accumulation inside the aeration head. However, the interface of this aeration head in practical use is relatively simple, and its applicability to sewage pipelines of different specifications and connection methods is poor. Therefore, we propose a membrane aeration head for sewage treatment. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] This utility model provides an improved membrane aeration head for wastewater treatment. Please refer to [link / reference]. Figures 1-4 The system includes: an aeration head housing 1, with a membrane ring 2 bolted to the upper end of the aeration head housing 1, the membrane ring 2 conforming to the external structure of the aeration head housing 1, an aeration membrane 3 laid on the inner side of the membrane ring 2, the aeration membrane 3 forming a detachable structure with the aeration head housing 1 via the membrane ring 2, the detachable aeration membrane 3 and membrane ring 2 facilitating maintenance and replacement; a connector ring 4 bolted to the lower end of the aeration head housing 1, a sleeve 5 connected to the lower end of the connector ring 4, the sleeve 5 forming a connection between the aeration head housing 1 and the membrane ring 2 via the connector ring 4, a convex ring 6 circumferentially distributed along the outer surface of the sleeve 5, and an opening 7 symmetrically positioned about the central axis of the sleeve 5, the opening 7 providing sewage input to the aeration head housing 1 when the sleeve 5 is not connected to a sewage pipeline; the lower end of the connector ring 4 bolted to the lower end of the aeration head housing 1. The aeration head is connected by an expansion ring 8, and a threaded sleeve 9 is connected to the lower end of the expansion ring 8. The threaded sleeve 9 forms a detachable structure with the connector ring 4 through the expansion ring 8, and the threaded sleeve 9 forms a communication connection with the connector ring 4 through the opening 7 and the sleeve 5. The threaded sleeve 9 and the sleeve 5 are used to adapt and connect to sewage pipes of different specifications and sizes, so that both the sleeve 5 and large-diameter threaded pipes can be easily connected to the aeration head. When sewage is input through the threaded sleeve 9, the multiple openings 7 on the sleeve 5 do not affect the sewage input rate, making the aeration head more applicable. A sealing ring 10 is provided at the connection between the expansion ring 8 and the sleeve 5, and the expansion ring 8 forms a sealing structure with the connector ring 4 through the sealing ring 10. The sealing ring 10 is used to prevent sewage input into the aeration head through the threaded sleeve 9 from seeping out from the connection between the expansion ring 8 and the connector ring 4, thereby improving the airtightness of the combined aeration head.

[0022] Please see Figure 2 and Figure 4 A wastewater treatment membrane aerator includes: an eccentric outlet hole 11 is provided on the upper outer wall of a connector ring 4, the eccentric outlet hole 11 is used to enable the wastewater output from the connector ring 4 to drive a roller brush 14 to rotate inside the aerator head housing 1 through potential energy; a support plate 12 is fixed on the upper inner wall of the aerator head housing 1, a support column is fixed on the lower surface of the middle part of the support plate 12, and the roller brush 14 is connected to the middle part of the support column through a rotating shaft, the rotating shaft is used to make the rotation of the roller brush 14 inside the aerator head housing 1 smoother and more stable; the roller brush 14 is symmetrically arranged about the central axis of the support column, and the roller brush 14 is rotatably connected to the aerator head housing 1 through the support column, the roller brush 14 is used to rotate inside the aerator head housing 1 through the drive of the wastewater output from the eccentric outlet hole 11 to clean the inside of the aerator head housing 1, and prevent the deposition of impurities and sediments that cause blockage of the aerator head.

[0023] Working principle: For this type of wastewater treatment membrane aerator, the operator first selects, based on the connection method of the wastewater pipeline, whether to directly install the wastewater pipeline onto the sleeve 5 for wastewater input, using multiple raised rings 6 on the sleeve 5 to strengthen the connection, or to install an expansion ring 8 on the connector ring 4 using threads and a sealing ring 10, and then thread a wastewater pipeline with a larger diameter onto the threaded sleeve 9, with wastewater input through the opening 7 on the sleeve 5. This aerator connects to the lower end of the detachable threaded sleeve 9 and the sleeve... Pipe 5 provides multiple sewage pipeline connection methods, making it more applicable in different sewage treatment scenarios. Subsequently, the sewage input in the sewage pipeline enters the aeration head housing 1, membrane ring 2, and aeration membrane 3 through the eccentric outlet hole 11 from the inside of the connector ring 4 for aeration. Finally, the sewage output from the eccentric outlet hole 11 will drive the roller brush 14 installed under the support plate 12 through the column 13 and the rotating shaft to rotate inside the aeration head housing 1, thereby cleaning the roller brush 14 inside the aeration head and preventing impurities or other sediments from accumulating and causing blockage of the aeration head.
